本发明的工作原理如下：The working principle of the present invention is as follows:
当开关11开启后，开关11带动顶杆8向后移动，顶杆8通过弹性连接件9带动阀芯10向后拉扯，在限位销10-3的压力下，使弹簧13开始压缩，同时阀芯10离开喷嘴口，此时发泡料从喷嘴口喷出；When the switch 11 is turned on, the switch 11 drives the ejector rod 8 to move backward, and the ejector rod 8 drives the valve core 10 to pull backward through the elastic connector 9. Under the pressure of the limit pin 10-3, the spring 13 starts to compress, and at the same time The valve core 10 leaves the nozzle opening, and the foaming material is ejected from the nozzle opening at this time;
若在喷涂时遇到角度的限制，可以握住阀芯管6，相对于阀芯管6旋转喷嘴7，从而实现对喷嘴7角度的调节；由于钢丝9-3以及球头5的存在，所以不会发生无法旋转的情况；并且球头5与球头连接座3尺寸相匹配，因此不转动阀芯管6时，球头5不会随意转动；If you encounter angle restrictions during spraying, you can hold the valve core tube 6 and rotate the nozzle 7 relative to the valve core tube 6 to realize the adjustment of the angle of the nozzle 7; due to the existence of the steel wire 9-3 and the ball head 5, so There will be no inability to rotate; and the ball head 5 matches the size of the ball head connecting seat 3, so when the valve core tube 6 is not rotated, the ball head 5 will not rotate at will;
当喷涂工作结束后，松开开关11，在弹簧13弹力的作用下，阀芯10复位，再次堵住喷嘴口，此时发生刚性密封，发泡料无法喷出。After the spraying work finished, unclamp switch 11, under the effect of spring 13 elastic force, spool 10 resets, blocked nozzle mouth again, and now rigid sealing takes place, and foaming material can't be ejected.
经过简单改装，本发明可以作为气枪使用。如图4、图5所示，枪管1的后部设置有用于连接上壶的上壶接口，上壶接口的一侧设置有快速接头18，快速接头18通过气管与外接气源相连接；上壶接口的顶部开设有上壶安装口19，上壶安装口19内活动设置有钢珠19-1，钢珠19-1在气压作用下能够向上运动，将上壶安装口19堵住。Through simple modification, the present invention can be used as an air gun. As shown in Figure 4 and Figure 5, the rear portion of the gun barrel 1 is provided with an upper pot interface for connecting the upper pot, and one side of the upper pot interface is provided with a quick joint 18, and the quick joint 18 is connected to an external air source through a gas pipe; The top of the last pot interface offers the last pot installation port 19, and steel ball 19-1 is movable in the last pot installation port 19, and steel ball 19-1 can move upwards under the action of air pressure, and the last pot installation port 19 is blocked.
当不使用发泡料进行喷涂作业时，打开外接气源，该发泡枪可作为气枪使用；由于钢珠19-1的存在，当气体进入枪管1的内腔后，钢珠19-1上顶，将上壶安装孔19堵住，因此不会发生漏气的情况。When the foaming material is not used for spraying operations, the external air source is turned on, and the foaming gun can be used as an air gun; due to the existence of the steel ball 19-1, when the gas enters the inner cavity of the gun barrel 1, the steel ball 19-1 goes up to the top , The upper pot installation hole 19 is blocked, so the situation of air leakage will not take place.
如图6所示，喷嘴7的前端可以连接辅助气嘴17。辅助气嘴17为前小后大的锥形气嘴。将发泡枪当作气枪使用时，辅助气嘴17能够将从喷嘴7喷出的气流形状整流成圆柱形，使气流更具有冲击力。As shown in FIG. 6 , the front end of the nozzle 7 can be connected with an auxiliary air nozzle 17 . The auxiliary gas nozzle 17 is a tapered gas nozzle with a small front and a large rear. When the foaming gun is used as an air gun, the auxiliary air nozzle 17 can rectify the shape of the airflow ejected from the nozzle 7 into a cylindrical shape, so that the airflow has more impact.
如图7所示，喷嘴7可以通过多个喷嘴连接件20连接阀芯管6的前端；喷嘴连接件20的后端螺纹部与阀芯管6的前端内螺纹部相配合，喷嘴连接件20的前端通过内螺纹部与喷嘴7的外螺纹部相配合。该结构通过拼装连接，能够使发泡枪进行弯折旋转，从而改变旋转角度，多个弯折角度的叠加能够使弯折的角度增大。As shown in Figure 7, the nozzle 7 can be connected to the front end of the valve core pipe 6 through a plurality of nozzle connectors 20; The front end of the nozzle is matched with the external thread portion of the nozzle 7 through the internal thread portion. The structure can be assembled and connected so that the foaming gun can be bent and rotated to change the rotation angle, and the superposition of multiple bending angles can increase the bending angle.
