Description

Technical Field

[0001] The utility model relates to the technical field of material belt conveying, in particular to a double-row traction knife seat mechanism. Background Art

[0002] In the die-cutting equipment, a traction knife holder is used to pull the material strip. If two material strips need to be pulled at the same time and the two material strips are die-cut by the die-cutting holder at the same time, the traditional method is to use two traction knife holders to pull the two material strips respectively. Since this method uses two traction knife holders, it will take up a large space of the whole machine and the cost is high, and when two traction knife holders are used to pull the two material strips respectively, the volume of the traction knife holder is large. In order to reduce the overall volume of the equipment, the two traction knife holders are staggered. This causes the material strip on the traction knife holder far away from the die-cutting knife holder to have a longer portion suspended in the air, and the material strip will shift, thereby causing processing errors, and workers are required to debug the two traction knife holders. The installation and debugging are troublesome, which affects the processing accuracy.

[0003] Therefore, a double-row traction knife seat mechanism is needed to solve the above problems. Utility Model Content

[0004] The utility model provides a double-row traction knife seat mechanism, which realizes synchronous or asynchronous traction of two material strips, makes the mechanism suitable for different processing requirements, increases the application range of the mechanism, integrates traction and die cutting on one knife seat, shortens the suspended length of the material strip, and thus improves the processing accuracy.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A double-row traction knife seat mechanism comprises a traction frame installed on the die-cutting knife seat, a traction roller assembly is arranged on the traction frame, the traction roller assembly comprises a traction roller driven by a first driving mechanism, the traction roller is arranged horizontally, and an end shaft is arranged horizontally at both ends of the traction roller, and both end shafts are rotatably installed on the traction frame, one of the end shafts is rotatably installed with a traction sleeve driven by a second driving mechanism, a pressure roller assembly is arranged above the traction roller assembly, and the pressure roller assembly is slidably installed on the traction frame in a vertical direction through a pneumatic drive device, and the pressure roller assembly comprises a support shaft, a first pressure roller that cooperates with the traction sleeve to pull the first material strip is rotatably installed on the support shaft, and a second pressure roller that cooperates with the traction roller to pull the second material strip is rotatably installed on the support shaft.

[0007] As a preferred technical solution, a rubber coating layer is provided on the outer peripheral surfaces of the first pressing roller, the second pressing roller, the traction sleeve and the traction roller.

[0008] As a preferred technical solution, the pneumatic drive device includes a pair of drive cylinders arranged on the traction frame, the piston rods of the drive cylinders pass through the traction frame and are jointly connected to a sliding frame, the support shaft is installed on the sliding frame, and a pair of guide columns are arranged between the sliding frame and the traction frame.

[0009] As a preferred technical solution, a pair of first bearings are arranged between the traction sleeve and the corresponding end shaft, a pair of second bearings are arranged between the support shaft and the first pressure roller, and a pair of third bearings are arranged between the support shaft and the second pressure roller.

[0010] As a preferred technical solution, a pair of limiting grooves for limiting the lifting and lowering of the support shaft are arranged on the traction frame, and both ends of the support shaft extend into the corresponding limiting grooves.

[0011] As a preferred technical solution, the traction frame is mounted on the die-cutting tool holder through a pair of mounting bolts.

[0012] As a preferred technical solution, the first driving mechanism includes a first driving motor, the first driving motor is transmission-connected with a first reducer, the first reducer is transmission-connected to the traction roller through a first coupling, and the second driving mechanism includes a second driving motor, the second driving motor is transmission-connected with a second reducer, the second reducer is transmission-connected to the traction sleeve through a second coupling.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0014] Since the double-row traction knife seat mechanism includes a mounting frame, when using this mechanism, the support shaft is first moved away from the traction roller through the pneumatic drive device, and then the first material belt is passed between the traction sleeve and the first pressure roller and then inserted into the die-cutting knife seat, the first material belt is passed between the traction roller and the second pressure roller, and then the first material belt and the second material belt are pressed tightly through the pneumatic drive device, and the traction of the first material belt and the second material belt is achieved under the drive of the first drive motor and the second drive motor. In the utility model, through the cooperation of the traction roller assembly and the pressure roller body assembly, this mechanism can simultaneously pull two material belts into the die-cutting knife seat at one time. In the process of pulling the material belt, the first material belt is set at The second material belt is arranged between the traction sleeve and the first pressure roller. Since the traction roller is driven by the first driving mechanism and the traction sleeve is driven by the second driving mechanism, the forward speed of the first material belt and the second material belt is controlled by controlling the first driving motor and the second driving motor respectively, thereby realizing the control of the first material belt and the second material belt entering the die-cutting knife holder position, that is, realizing synchronous or asynchronous traction of the two material belts, making this mechanism suitable for different processing requirements, increasing the scope of use of this mechanism, integrating traction and die-cutting on one knife holder, simplifying the structure, reducing the occupied space, and shortening the suspended length of the material belt, thereby improving the processing accuracy.

[0015] Since the double-row traction knife seat mechanism includes a pneumatic drive device, during the use of this device, the position adjustment of the support shaft in the vertical direction is realized through two driving cylinders, that is, the distance adjustment between the traction sleeve and the first pressure roller, and the distance adjustment between the traction roller and the second pressure roller are realized, making this mechanism suitable for traction of material strips of different thicknesses.
