Lockstitch button holder driving mechanismTechnical field
The utility model belongs to sewing machine technique field, is related to a kind of lockstitch button holder driving mechanism.
Background technology
Lockstitch button holder is very important a kind of equipment in garment machinery, and lockstitch button holder is mainly used for processing the button in all kinds of dress ornamentsHole is divided into straight buttonholing machine and eyelet buttonhole sewing machine, is divided into ending and does not finish up two kinds.
Traditional lockstitch button holder driving and transmission device are to be moved by a upper shaft rotation of servo motor driving, then pass through synchronous driveLower axle rotates, to realize that upper and lower axle links.Since upper and lower axle links, cause, when adjusting rotating shuttle position angle, to influence whetherThe variation of eedle position, so that eedle position is easy positioning, in order to enable rotating shuttle position angle and eedle position are adjusted toPosition may result in appearance and debug repeatedly.Simultaneously as sewing knitting fabric is different with the eedle high and low position of shuttle-woven fabric, everyWhen between secondary knitting fabric and shuttle-woven fabric switching, also it is required for being debugged again, it is very inconvenient, reduce efficiency.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, it is proposed that lockstitch button holder easy to use drivesMotivation structure.
The purpose of this utility model can be realized by following technical proposal：
Lockstitch button holder driving mechanism, including rack, the rack are equipped with upper axis and lower axle, which is characterized in that describedRack is equipped with motor one, and the motor one is drivingly connected with upper axis, and motor two, the electricity are additionally provided in the rackMachine two is drivingly connected with lower axle.
In this lockstitch button holder driving mechanism, since upper axis is controlled by different motor one and motor two respectively from lower axle, onThe position of both axis and lower axle in debugging process due to there is no upper and lower axle interaction relation, eedle position and rotating shuttle angleDegree position adjusting be independent from each other, be not associated with so that the adjusting of eedle position and rotating shuttle angle position it is more convenient andIt can be easier to adjust and arrive accurate location.When being replaced between knitting fabric and shuttle-woven fabric, the position of upper axis and lower axle is adjustedWill not influence each other so that lockstitch button holder it is more convenient to use.
In above-mentioned lockstitch button holder driving mechanism, the motor one and upper axis are coaxial, the motor one and upper axis itBetween be equipped with shaft coupling one.
This structure so that lockstitch button holder structure is compacter.
In above-mentioned lockstitch button holder driving mechanism, the motor two and lower axle are coaxial, the motor two and lower axle itBetween be equipped with shaft coupling two.
This structure so that lockstitch button holder structure is compacter.
In above-mentioned lockstitch button holder driving mechanism, the rack be equipped with it is automatically controlled, the motor one and motor two withAutomatically controlled electrical connection.
The angle and rotating speed of automatically controlled control motor one and motor two can be passed through.
In above-mentioned lockstitch button holder driving mechanism, it is described it is automatically controlled include storage unit, have in the storage unitIt is knitted fabric parameter and shuttle-woven fabric parameter.
Knitting fabric parameter is the one group of angle and rotary speed parameter of corresponding motor one and motor two, and shuttle-woven fabric parameter is pairAnother group of angle and rotary speed parameter of motor one and motor two are answered, therefore, after replacing fabric type, only needs to change eedle, soCorresponding parameter is called by automatically controlled so that lockstitch button holder uses more convenient afterwards.
It is also stored in above-mentioned lockstitch button holder driving mechanism, in the storage unit and corresponds to motor one and motor respectivelyTwo first zero arrange parameter and the second reset parameter, it is described it is automatically controlled can be according to first zero arrange parameter and secondReset parameter controls motor one respectively and dead-center position is arrived in the playback of motor two.
Compared with prior art, lockstitch button holder driving mechanism, since upper axis and lower axle are controlled by motor one and motor two respectively,So that upper axis and lower axle will not influence each other in debugging process so that lockstitch button holder debugging process and use process are more convenient.

Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made furtherDescription, but the utility model is not limited to these examples.
As depicted in figs. 1 and 2, this lockstitch button holder driving mechanism includes rack 1.Rack 1 is equipped with upper axis 2 and lower axle 3.Upper axis2 are connected with the eedle mechanism 8 being arranged in rack 1, and lower axle 3 is connected with the rotary shuttle mechanism 9 being arranged in rack 1.
Rack 1 is equipped with motor 1, and motor 1 is drivingly connected with upper axis 2, and motor 1 and upper axis 2 are coaxial, motor oneShaft coupling 1 is equipped between 4 and upper axis 2.Motor 25 is additionally provided in rack 1, motor 25 is drivingly connected with lower axle 3, and motor25 is coaxial with lower axle 3, and shaft coupling 27 is equipped between motor 25 and lower axle 3.This structure so that lockstitch button holder structure is more stepped upIt gathers.
Rack 1 be equipped with it is automatically controlled, motor 1 is electrically connected with motor 25 with automatically controlled.It can independently be controlled by automatically controlledThe angle and rotating speed of motor 1 and motor 25 processed.Automatically controlled includes storage element, and knitting is stored in storage elementFabric parameter and shuttle-woven fabric parameter.Knitting fabric parameter is one group of angle and the rotating speed ginseng of corresponding motor 1 and motor 25Number, shuttle-woven fabric parameter are another group of angle and rotary speed parameter of corresponding motor 1 and motor 25, therefore, are replacing fabric kindAfter class, eedle is only needed to change, then calls corresponding parameter by automatically controlled so that lockstitch button holder uses more convenient.StorageThe first zero arrange parameter for corresponding to motor one and motor two respectively and the second reset parameter are also stored in unit, it is describedIt is automatically controlled to control motor one and the playback of motor two respectively according to first zero arrange parameter and the second reset parameter to zeroPoint position.
In this lockstitch button holder driving mechanism, since upper axis 2 is controlled by different motors 1 and motor 25 respectively from lower axle 3The position of both system, upper axis 2 and lower axle 3 will not influence each other in debugging process, therefore so that the use of lockstitch button holder is more squareJust.When being replaced between knitting fabric and shuttle-woven fabric, the position of upper axis 2 and lower axle 3 adjusts and will not influence each other so that lockEye machine it is more convenient to use.
