The existing cooling and forming roller device includes at least two cooling rollers arranged in the up and down direction, and the gap between the adjacent cooling rollers is melt. The melt extruded by the extruder passes through all the channels in turn and then is cooled and formed into a plate. The plate is punched by the punching knife of the punching die to obtain a perforated plate, and the orifice plate can be stretched to obtain a breeding grid. The mesh side length of existing breeding grids is generally greater than 20mm. In order to obtain breeding grids with smaller meshes to meet the breeding needs of small animals such as chicks and ducklings, it is necessary to reduce the diameter or side length of the punching knife. However, the following problem is that because the plate is hard, the thinned punching knife is easily damaged when punching, but in order to ensure the quality of the breeding grid, as long as the punching knife is damaged, it needs to be stopped for replacement. This will seriously affect production efficiency, and maintenance costs are high.

具体实施方式Detailed ways

下面结合附图和具体实施例对本发明做详细说明：The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments:

具体实施例，如图1至图9所示，18mm以下养殖格栅网生产用的冷却成型辊装置，包括沿上下方向排列的至少两个冷却辊1，相邻冷却辊1之间的间隙为熔体2的通道，在其中一个冷却辊1的外圆周面上设置有至少一个打孔针组，同一个打孔针组的所有打孔针3在冷却辊1的外圆周面上呈阵列式排列。打孔针组的数量为至少两个，所有的打孔针组在冷却辊1的外侧壁上沿圆周方向均匀排列，如图7和图8所示。A specific embodiment, as shown in Figures 1 to 9, the cooling forming roll device for the production of aquaculture grid nets below 18mm includes at least twocooling rolls 1 arranged in the up-down direction, and the gap betweenadjacent cooling rolls 1 is In the channel of themelt 2, at least one perforated needle group is arranged on the outer circumferential surface of one of thecooling rolls 1, and all theperforated needles 3 of the same perforated needle group are arranged on the outer circumferential surface of thecooling roll 1 in an array type arrangement. The number of punching needle groups is at least two, and all punching needle groups are evenly arranged along the circumferential direction on the outer side wall of thecooling roll 1 , as shown in FIG. 7 and FIG. 8 .

打孔针3的长度L小于等于3.5mm，在确保满足打孔深度需求的前提下，尽可能地减小打孔针3的长度，可以减少用料，节约成本。相邻两个打孔针3之间的中心距小于等于7mm，确保拉伸后获得所需大小的网孔。The length L of thepunching needle 3 is less than or equal to 3.5 mm. On the premise of ensuring that the punching depth requirement is met, the length of thepunching needle 3 can be reduced as much as possible, which can reduce materials and save costs. The center-to-center distance between twoadjacent punching needles 3 is less than or equal to 7 mm to ensure that the desired size of mesh can be obtained after stretching.

打孔针3与冷却辊1之间为可拆卸式连接。例如在冷却辊1上开设螺纹孔，将打孔针3与冷却辊1螺纹连接，或者是，利用螺钉或螺栓将打孔针3与冷却辊1固定在一起，当打孔针3损坏后，方便拆装更换。The punchingneedle 3 and thecooling roller 1 are detachably connected. For example, threaded holes are opened on thecooling roller 1, and the punchingneedle 3 is threadedly connected to thecooling roller 1, or, the punchingneedle 3 and thecooling roller 1 are fixed together with screws or bolts. When thepunching needle 3 is damaged, Easy to disassemble and replace.

打孔针3为圆锥体结构，如图4所示，或为圆台体结构，如图5和图6所示，圆锥体结构或圆台体结构的底面与冷却辊1连接。用户可以根据自己的实际需求选择打孔针3的形状，可以更好地满足不同用户的使用需求。打孔针3的顶部还可以设置成中间向外凸起的圆弧面或其他任何形状。Thepunching needle 3 has a cone structure, as shown in FIG. 4 , or a truncated cone structure, as shown in FIG. 5 and FIG. Users can choose the shape of thepunching needle 3 according to their actual needs, which can better meet the needs of different users. The top of thepunching needle 3 can also be set as a circular arc surface with the middle outwardly bulging or any other shape.

打孔针3为圆台体结构，在打孔针3的顶面上开设有凹槽3-1，凹槽3-1为倒置的圆台状结构。如图6所示，打孔针3插入到熔体2内时，部分多余的废料挤入到凹槽3-1内，使得位于打孔针3外围的待拉伸部分的形变量较小，可以提高后续产品的质量。为了使打孔针3具有足够大的强度，同时具有足够大的容纳空间，本发明将凹槽3-1的深度与打孔针3的长度L之比设置为1：(2-5)。Thepunching needle 3 has a circular truncated structure, a groove 3-1 is formed on the top surface of thepunching needle 3, and the groove 3-1 is an inverted circular truncated structure. As shown in FIG. 6 , when thepunching needle 3 is inserted into themelt 2, part of the excess waste material is squeezed into the groove 3-1, so that the deformation of the part to be stretched on the periphery of thepunching needle 3 is small, The quality of subsequent products can be improved. In order to make thepunching needle 3 have sufficient strength and a sufficient accommodation space, the present invention sets the ratio of the depth of the groove 3-1 to the length L of thepunching needle 3 as 1:(2-5).

打孔针3的底面直径小于等于2.5mm。避免孔太大而导致熔体2断裂。The diameter of the bottom surface of thepunching needle 3 is less than or equal to 2.5 mm. Avoid holes that are too large to causemelt 2 to break.

打孔针3的排列方式有很多种，本发明中给出以下两种：There are many arrangements ofpunching needles 3, and the following two are provided in the present invention:

第一种，阵列式排列为与冷却辊1的中心轴线平行的直线式等间距排列，如图7所示；第二种，阵列式排列为绕冷却辊1的中心轴线呈螺旋式的等间距排列，如图8所示，同一打孔针组中相邻两个打孔针3的中心点连线与冷却辊1的轴线之间的夹角α为锐角且优选为10°-30°。用户可以根据自己的需求选择打孔针3的排列方式。The first, the array arrangement is a linear and equal-spaced arrangement parallel to the central axis of thecooling roll 1, as shown in Figure 7; Arrangement, as shown in FIG. 8 , the included angle α between the center point connecting line of twoadjacent punching needles 3 in the same punching needle group and the axis of thecooling roller 1 is an acute angle and preferably 10°-30°. Users can choose the arrangement of thepunching needles 3 according to their own needs.

在满足将熔体2压平、冷却的前提下，尽可能地减少冷却辊1的数量可以节约成本，所以本发明将冷却辊1的数量设置为三个，三个冷却辊1沿竖直方向排列且下方两个冷却辊1之间的通道为冷却成型辊装置的进料口，打孔针组设置在最下方或中间的冷却辊1上，熔体2由挤压机出来后就与打孔针3接触，此时熔体2的温度较高，打孔针3更容易刺入熔体2内。On the premise of flattening and cooling themelt 2, reducing the number ofcooling rolls 1 as much as possible can save costs. Therefore, in the present invention, the number ofcooling rolls 1 is set to three, and the threecooling rolls 1 are in the vertical direction. The channel between the twocooling rolls 1 arranged and below is the feed port of the cooling forming roll device, the punching needle group is arranged on the lowermost ormiddle cooling roll 1, and themelt 2 is mixed with the punching machine after it comes out of the extruder. When theperforated needles 3 are in contact, the temperature of themelt 2 is higher at this time, and theperforated needles 3 are more likely to penetrate into themelt 2 .

打孔针3的长度L可以小于、等于或者是大于相邻两个冷却辊1之间的最小间隙，当打孔针3的长度L小于相邻两个冷却辊1之间的最小间隙时，如图1至图3所示，此时打孔针3不能穿透熔体2，在熔体2上打出的孔为盲孔。在这种情况下，打孔针3顶面上开设的凹槽3-1可以将熔体2分为位于打孔针3外围的待拉伸部分及位于凹槽3-1内部的废料部分，凹槽3-1的侧壁与打孔针3的轴线之间的夹角大于打孔针3的外壁与打孔针3的轴线之间的夹角，通过较大斜度的凹槽3-1，使得废料部分与待拉伸部分之间可以分离较大距离，避免被分离的部分再重新粘连，而且多余的废料部分挤入到凹槽3-1内，使得位于打孔针3外围的待拉伸部分的形变量较小，可以提高后续产品的质量。同时，因为打孔针3不能穿透熔体2，所以废料部分与待拉伸部分之间有部分粘连，废料部分不会被打孔针3切断，而是在后续拉伸中被扯断，可以防止打孔针3上的凹槽3-1被堵塞。本发明将凹槽3-1的侧壁与打孔针3的外壁之间的夹角设置为30°-60°。The length L of thepunching needle 3 can be less than, equal to or greater than the minimum gap between the twoadjacent cooling rolls 1. When the length L of the punchingneedle 3 is less than the minimum gap between the two adjacent cooling rolls 1, As shown in FIGS. 1 to 3 , at this time, the punchingneedle 3 cannot penetrate themelt 2 , and the holes punched in themelt 2 are blind holes. In this case, the groove 3-1 opened on the top surface of the punchingneedle 3 can divide themelt 2 into the part to be stretched on the periphery of the punchingneedle 3 and the waste part located inside the groove 3-1, The angle between the side wall of the groove 3-1 and the axis of the punchingneedle 3 is greater than the angle between the outer wall of the punchingneedle 3 and the axis of the punchingneedle 3, and the groove 3- 1, so that the waste part and the part to be stretched can be separated by a large distance, so as to avoid re-adhesion of the separated part, and the excess waste part is squeezed into the groove 3-1, so that the outer part of the punchingneedle 3 The deformation amount of the part to be stretched is small, which can improve the quality of subsequent products. At the same time, because the punchingneedle 3 cannot penetrate themelt 2, there is a partial adhesion between the waste part and the part to be stretched, and the waste part will not be cut by the punchingneedle 3, but will be torn off in the subsequent stretching, The groove 3-1 on thepunch 3 can be prevented from being blocked. In the present invention, the included angle between the side wall of the groove 3-1 and the outer wall of the punchingneedle 3 is set to 30°-60°.

当打孔针3的长度L大于等于相邻两个冷却辊1之间的最小间隙时，与带打孔针3的冷却辊1相邻的冷却辊1包括冷却辊本体1-1及固定在冷却辊本体1-1外围的硅胶层1-2。如图9所示，以冷却辊1的数量为三个且打孔针3位于中间的冷却辊1上为例，此时位于上方和下方的两个冷却辊1都是包括冷却辊本体1-1和硅胶层1-2，打孔针3的针尖穿过熔体2后插入到硅胶层1-2内，确保能在熔体2上打出通孔，拉伸时更加省力，同时可以避免打孔针3直接与硬质的冷却辊1接触而断裂或被磨损。When the length L of the perforated needles 3 is greater than or equal to the minimum gap between two adjacent cooling rolls 1, thecooling roll 1 adjacent to thecooling roll 1 with theperforated needles 3 includes a cooling roll body 1-1 and a The silica gel layer 1-2 on the periphery of the cooling roller body 1-1. As shown in FIG. 9 , taking the number ofcooling rollers 1 as three and the punching needles 3 located on thecooling roller 1 in the middle as an example, at this time, the twocooling rollers 1 located above and below both include the cooling roller body 1- 1 and the silicone layer 1-2, the tip of the punchingneedle 3 is inserted into the silicone layer 1-2 after passing through themelt 2 to ensure that through holes can be punched in themelt 2, which is more labor-saving when stretching, and can avoid punching. Thehole pin 3 is broken or worn in direct contact with thehard cooling roll 1 .

本发明在具体使用时，打孔针3可以设置在最下方的冷却辊1上，如图1所示；也可以设置在中间的冷却辊1上，如图2所示；或者是设置在最上方的冷却辊1上，如图3所示。以图2所示为例，三个冷却辊1直径相等且在挤压机的出料口后方沿竖直方向排列，冷却辊1的长度方向沿左右方向设置，打孔针3固定在中间的冷却辊1上，打孔针3的排列方式为上面说到的第一种，打孔针3的长度L与熔体2的厚度h之比为(0.55-0.95)：1，例如当熔体2的厚度h为3mm时，打孔针3的长度为2.8mm。打孔针3为方形时，打孔针3的边长小于等于2.5mm；打孔针3为圆形时，打孔针3的直径小于等于2.5mm；打孔针3为菱形时，打孔针3的对角线长度小于等于2.5mm。In the specific use of the present invention, the punchingneedle 3 can be arranged on thelowermost cooling roller 1, as shown in FIG. 1; it can also be arranged on themiddle cooling roller 1, as shown in FIG. 2; or it can be arranged at the lowest On top of thecooling roll 1, as shown in Figure 3. Taking Fig. 2 as an example, the threecooling rollers 1 have the same diameter and are arranged in the vertical direction behind the discharge port of the extruder. On thecooling roll 1, the arrangement of the punching needles 3 is the first one mentioned above, and the ratio of the length L of the punching needles 3 to the thickness h of themelt 2 is (0.55-0.95): 1. For example, when the melt When the thickness h of 2 is 3 mm, the length of thepunch 3 is 2.8 mm. When the punchingneedle 3 is a square, the side length of the punchingneedle 3 is less than or equal to 2.5mm; when the punchingneedle 3 is a circle, the diameter of the punchingneedle 3 is less than or equal to 2.5mm; when the punchingneedle 3 is a diamond, the punching The diagonal length of theneedle 3 is less than or equal to 2.5mm.

如图2所示，由挤压机挤出的熔体2由前向后经过最下方的冷却通道即下方两个冷却辊1之间的通道后，绕过中间冷却辊1的后侧，再经过上方两个冷却辊1之间的通道，然后绕过上方冷却辊1的前侧，经过上方冷却辊1的顶部后，冷却成型为带有盲孔的板材，将板材拉伸即可得到养殖格栅网。As shown in Figure 2, themelt 2 extruded by the extruder passes through the lowermost cooling channel, that is, the channel between the two lower cooling rolls 1, from front to back, then bypasses the rear side of themiddle cooling roll 1, and then After passing through the passage between the twoupper cooling rollers 1, and then bypassing the front side of theupper cooling roller 1, after passing through the top of theupper cooling roller 1, it is cooled and formed into a plate with blind holes, and the plate is stretched to obtain culture. grille mesh.

为了使得养殖格栅网具有足够高的韧性，在拉伸时需要对板材施加足够大的拉力，现有冲刀的直径或者是边长较大，所以得到的冲孔的直径或者是边长也就较大，如果减小拉力，也可以使最后所得养殖格栅网的网孔边长变小，但是拉力减小后，所得养殖格栅网的韧性就会降低，无法满足使用需求，所以才会采用减小冲刀的直径或者边长的方式来获得小网孔的养殖格栅网，但是冲刀变细后就容易损坏。所以，本发明在冷却辊1上增加打孔针3，在熔体2经过下方两个冷却辊1之间的通道时，打孔针3对熔体2进行打孔操作，在熔体2上形成盲孔，因为熔体2经过打孔针3时的温度较高，所以此时熔体2的硬度较低，打孔针3受到的阻力较小，所以打孔针3的损坏几率较低，停机更换打孔针3的频率也就较低，所以本发明可以提高生产效率，节约维护成本，而且结构简单，使用方便。In order to make the breeding grids have high enough toughness, it is necessary to exert a sufficient pulling force on the plate during stretching. The diameter or side length of the existing punching knife is relatively large, so the diameter or side length of the obtained punching hole is also If the tension is reduced, the side length of the mesh of the finally obtained aquaculture grid can also be reduced, but after the tension is reduced, the toughness of the obtained aquaculture grid will be reduced, which cannot meet the needs of use. The small-mesh aquaculture grille net will be obtained by reducing the diameter or side length of the punching knife, but it is easy to damage when the punching knife becomes thinner. Therefore, in the present invention, a punchingneedle 3 is added to thecooling roll 1. When themelt 2 passes through the channel between the twocooling rolls 1 below, the punchingneedle 3 performs a punching operation on themelt 2. Blind holes are formed, because the temperature of themelt 2 passing through the punchingneedle 3 is higher, so the hardness of themelt 2 is lower at this time, and the resistance of the punchingneedle 3 is smaller, so the damage probability of the punchingneedle 3 is lower. Therefore, the frequency of replacing the punchingneedle 3 when the machine is stopped is low, so the present invention can improve the production efficiency, save the maintenance cost, and has a simple structure and convenient use.

另外，因为本发明中的打孔针3较细，所以打出的孔也就较细，拉伸时，可以对板材施加足够大的拉力，从而获得既满足韧性需求、又使得网孔边长小于等于18mm的小网孔的养殖格栅网，从而满足雏鸡、雏鸭等小动物的养殖需求。In addition, because the punchingneedle 3 in the present invention is relatively thin, the punched holes are also relatively thin. When stretching, a sufficient pulling force can be applied to the plate, so as to meet the toughness requirements and make the mesh side length less than The breeding grille net with small meshes equal to 18mm can meet the breeding needs of small animals such as chicks and ducklings.
