The cross-sectional area of ​​the positioning portion is larger than the cross-sectional area of ​​the through hole 421, and is fitted with the side wall of the connecting arm 42, which has a good positioning effect, so that the cam 41 can be well accommodated in the through hole 421; vertically arranged linear guide rails 16 are fixedly connected at both ends of the frame body 1, and the upper tool holder 3 extends into the linear guide rails 16 and is slidably connected to the inner wall of the linear guide rails 16. The setting of the linear guide rails 16 limits the moving trajectory of the upper tool holder 3, and by setting a transmission structure, the rotating shaft 4 is rotated to drive the cam 41 to rotate in the through hole 421. Due to the eccentric setting, the rotation of the cam 41 can drive the connecting arm 42 to move. Due to the limitation of the moving trajectory of the upper tool holder 3, the upper tool holder 3 performs reciprocating motion in the vertical direction;

[0024] The driving structure includes a first driving motor 61 and a first pulley 611 and a second pulley 612 connected by belt transmission, and one end of the rotating shaft 4 extends toward the second pulley 612 and is fixedly connected; a protective box 6 for accommodating the first pulley 611 and the second pulley 612 is fixedly connected to one side of the frame 1, and the first driving motor 61 is fixedly connected to one side of the protective box 6, and the output shaft of the first driving motor 61 extends into the protective box 6 and is fixedly connected to the first pulley 611 through a coupling; the protective box 6 can be used to protect the first pulley 611 and the second pulley 612, and the first pulley 611 and the second pulley 612 will not be exposed to the outside, thereby ensuring the service life, and the first pulley 611 and the second pulley 612 are set, and because they are connected by belt transmission, they are flexible transmission connections, thereby ensuring the range of false touch and ensuring the fixing effect of the rotating shaft 4 and the entire driving structure;

An inclined guide surface is provided at one end of the stripping member 5 facing the lower knife frame 2. Due to the setting of the guide surface, it has a good guiding effect. When stripping is required, the material passes over the pulling roller 111 and is fed to the top of the stripping member 5. It follows the gap between the stripping member 5 and the lower knife frame 2 and then passes through the pulling roller 111 from below again. Due to the action of the guide surface at the end of the stripping member 5, the upper and lower layers of the material are stripped, the upper layer of the material is fed to the top of the lower knife frame 2, and the lower layer of the material passes through the pulling roller 111 from below, thereby completing the automatic stripping of the material.

[0026] One side of the frame 1 is located above the first drive motor 61 and is fixedly connected to a second drive motor 11. The output shaft of the second drive motor 11 is fixedly connected to one end of the pulling roller 111 through a coupling. The tops of both sides of the frame 1 are fixedly connected to lifting cylinders 12. Both ends of the pressure roller 122 are rotatably connected to lifting blocks 121. The output end of the lifting cylinder 12 is fixedly connected to the lifting block 121.

A limiting roller 15 is provided on the top of the feeding end of the frame 1. A plurality of limit members 151 are sleeved on the limit roller 15, and the limit members 151 can be fixedly connected to the limit roller 15 by bolts. When the material needs to be compounded, the positions of the two limit members 151 on the limit roller 15 are adjusted, and the distance between the two limit members 151 is controlled, so that the composite material bypasses the top of the limit roller 15 and is located between the two limit members 151. The two limit members 151 are used to prevent the composite material from deflecting during transportation, and the transportation effect is guaranteed. After passing through the limit roller 15, the composite material is transported to the bottom of the pressing roller 122, and the lifting cylinder 12 is used to bring the root close to the pulling roller 111 to achieve pressing and ensure the compounding effect.

[0027] The top of the upper tool holder 3 is provided with three connecting seats 32, one side of two of the connecting seats 32 is fixedly connected with a dial indicator 322, and the side of the upper tool holder 3 away from the drawing roller 111 is movably connected with a blade clamp seat 31 for fixing the blade in the vertical direction, the measuring head of the dial indicator 322 contacts the top of the blade clamp seat 31, an adjusting screw 321 is threadedly connected to the connecting seat 32, and a limiting portion 3211 is integrally formed at the bottom end of the adjusting screw 321, and a groove 311 for accommodating the limiting portion 3211 is provided at the top of the blade clamp seat 31, and the limiting portion 3211 is accommodated in the groove 311, so as to realize that the bottom end of the adjusting screw 321 is aligned with the blade The blade clamp seat 31 is rotatably connected, and a strip groove is provided on the blade holder seat, and a bolt passes through the strip groove and is threadedly connected to the upper blade holder 3; the movement trajectory of the blade clamp seat 31 is limited by the cooperation of the bolt and the strip groove; an adjusting screw 321 is provided, and multiple screws are provided, so that the blade clamp seat 31 can be moved up and down more stably, and the threaded cooperation can more accurately control the distance of the up and down movement, and cooperate with the dial indicator 322, the accuracy of the dial indicator 322 is 0.01mm, which further ensures the accuracy of the blade clamp seat 31, and also ensures the reciprocating distance of the blade clamp seat 31, ensures the cutting accuracy, and prevents the bottom film from being cut off.

[0028] Two first guide rollers 13 are arranged at an interval up and down at the feeding end of the frame 1, and two second guide rollers 14 are arranged at an interval up and down below the supporting roller 51. The material to be stripped follows the upper first guide roller 13, passes above the pulling roller 111, and reaches the stripping piece 5 on the supporting roller 51, and bypasses the stripping piece 5, passes under the pulling roller 111, and returns to the first guide roller 13 located below. The two first guide rollers 13 have a good guiding effect and ensure the transportation effect; and the two second guide rollers 14 are provided. When the bottom film material is transported, it passes through the second guide rollers 14 and then reaches the top of the lower knife frame 2, which can effectively prevent the bottom film material from sticking to the material to be stripped in the early stage, further ensuring the transportation effect.

[0029] Working principle: the material to be peeled is passed along the first guide roller 13 located at the top, and passes above the material pulling roller 111, until it reaches the peeling piece 5 on the support roller 51, and bypasses the peeling piece 5. Due to the action of the guide surface at the end of the peeling piece 5, the upper and lower layers of the material are peeled off, and the upper layer of the material is sent to the top of the lower knife holder 2. The lower layer of the material passes through the material pulling roller 111 from below, until it is returned to the first guide roller 13 located at the bottom. The bottom film material passes between the two second guide rollers 14 and along the gap between the peeling piece 5 and the lower knife holder 2, and also reaches the top of the lower knife holder 2, and is located below the upper layer of the material. At this time, the first The driving motor 61 rotates the rotating shaft 4, driving the cam 41 to rotate in the through hole 421. Due to the eccentric setting, the rotation of the cam 41 can drive the connecting arm 42 to move. Due to the limitation of the moving trajectory of the upper tool holder 3, the upper tool holder 3 performs reciprocating motion in the vertical direction. The cutting knife clamp of the upper tool holder 3 presses the material and performs precise cutting. The second driving motor 11 drives the pulling roller 111 to complete the feeding of the upper material, which can arrange the upper material on the base film material at a certain interval. The overall structure is more automated, which ensures work efficiency and saves the consumption of raw materials.
