[0040] Specifically, the degumming component 10 includes a synchronous belt 11, a driving wheel 12 arranged at one end of the inner side of the synchronous belt 11, a driven wheel 13 arranged at the other end of the inner side of the synchronous belt 11, and a driving element 14 connected to the driving wheel 12; the driving element 14 drives the synchronous belt 11 to rotate. In this embodiment, the driving element 14 adopts a rotating motor.

[0041] Furthermore, the degumming mechanism also includes a guide block 15, on which a guide groove 151 is provided along the length direction of the synchronous belt 11; the synchronous belt 11 passes through the guide groove 151 and the top of the guide block 15 in sequence, and the guide block 15 limits the movement direction of the synchronous belt 11 and provides the working stability of the synchronous belt 11. A baffle 152 is fixedly provided on one side of the guide block 15, and the baffle 152 is provided on one side of the opening of the guide groove 151. The baffle 152 blocks the opening of the guide groove 151 to prevent the synchronous belt 11 from being disengaged. A limit block 153 is also provided at the upper end of the guide block 15. The limit block 153 and the baffle 152 are an integrated structure, and together form an L-shaped structure. A downwardly inclined pressing portion 154 is provided at one end of the limit plate, and the synchronous belt 11 passes between the limit block 153 and the guide block 15, and the pressing portion 154 presses the synchronous belt 11 downward, so that the synchronous belt 11 can work in contact with the top surface of the guide block 15. A clearance groove 155 is also provided on one side of the guide block 15 .

[0042] Specifically, the rubber cutting assembly 20 includes a driving cylinder 21 disposed on the side of the synchronous belt 11, a knife seat 22 drivingly connected to the driving cylinder 21 and facing the side of the synchronous belt 11, and a knife 23 fixed on the knife seat 22; the driving cylinder 21 drives the knife 23 to move along the length direction of the synchronous belt 11 to achieve cutting.

[0043] Specifically, the easy-tear cutting mechanism of the utility model also includes a supporting base plate 30. The degumming component 10 and the glue cutting component 20 are both arranged on the supporting base plate 30. The supporting base plate 30 plays the role of bearing and connecting with the external structure. A driving wheel mounting seat 31 rotatably connected to the driving wheel 12 and a driven wheel mounting seat 32 rotatably connected to the driven wheel 13 are fixedly provided on the supporting base plate 30. Rotating bearings are provided on the driving wheel mounting seat 31 and the driven wheel mounting seat 32.

[0044] The working principle of the easy-tear cutting mechanism involved in the utility model is as follows:

[0045] 1. If Figure 5 As shown, the double-sided tape 40 is attached to the synchronous belt 11 by utilizing the viscosity of the colloid 41;

[0046] 2. The driving cylinder 21 drives the cutter 23 to move along the length direction of the synchronous belt 11 to achieve cutting. Figure 6 As shown, a fracture 43 is formed on the colloid 41, and the colloid 41 is divided into a retaining portion 41a and a discarding portion 41b;

[0047] 3. If Figure 7 As shown, the double-sided tape 40 is lifted up, and due to the viscosity of the colloid 41 , the discarded portion 41 b is separated from the release paper 42 and adhered to the synchronous belt 11 , and the retained portion 41 a is lifted up along with the release paper 42 , thereby forming an easy-tear opening 44 .

[0048] Compared with the prior art, the easy-tear cutting mechanism involved in the utility model can automatically complete the processing of the easy-tear edge of the double-sided tape, ensuring processing accuracy and efficiency; specifically, a degumming component and a glue cutting component are provided, the degumming component includes a synchronous belt, and the glue cutting component includes a driving cylinder and a tool, the double-sided tape is bonded to the synchronous belt, the driving cylinder drives the tool to cut the colloid of the double-sided tape, the cut colloid is separated from the isolation paper and adhered to the synchronous belt, forming an easy-tear edge, and the processing efficiency and processing accuracy are high; at the same time, the driving cylinder drives the tool to move horizontally along the synchronous belt for cutting, which can avoid cutting the isolation paper.

[0049] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
