[0029] The electrostatic generating mechanism 200 is used to generate static electricity on the surface of the film during the winding and rewinding and breaking process by the high-voltage electrostatic generator 203, so that the film has adsorption force, and the film can be attached to the axis of the new roll without using consumables such as double-sided tape, thereby effectively reducing the production cost.

[0030] Specifically, the bearing mechanism 100 further comprises a first winding shaft rod 106 hingedly arranged in the inner cavity of the bearing frame 101, a second winding shaft rod 107 hingedly arranged in the inner cavity of the bearing frame 101, and an electrostatic eliminator 108 fixedly installed on the bottom of the horizontal plate 202.

[0031] The electrostatic eliminator 108 is installed above the surface of the film at a distance of 2 to 10 cm from the film, can neutralize the static electricity on the surface of the film instantly, avoid the static electricity attracting dust and other impurities, and further improve the quality of the product.

[0032] Further, the film breaking assembly 102 comprises a support arm 102a fixedly installed on the top of the bearing frame 101, a rotating rod 102b rotatably installed on the inner side of the support arm 102a, and a cylinder 102c fixedly installed on the outer surface of the rotating rod 102b, and the film breaking assembly 102 further comprises a limiting disc 102d fixedly installed on the outer surface of the cylinder 102c, and a pneumatic cylinder 102e fixedly installed on the outer side of the support arm 102a.

[0033] The pneumatic cylinder 102e and the rotating rod 102b in the film breaking assembly 102 cooperate to automatically complete the film breaking operation during rewinding, which is connected with the automatic rewinding function, so that the whole winding process is more smooth and efficient, and the production efficiency is further improved.

[0035] The driving motor 103b in the flying knife assembly 103 drives the connecting rod 103c and the high-speed steel blade 103d to rotate, which can quickly and accurately cut the film, ensure the flatness of the film cutting position, and facilitate the subsequent winding work, thereby improving the overall quality of the product.

[0036] Further, the blowing assembly 105 includes a fixed seat 105a fixedly installed in the inner cavity of the bearing frame 101, a gas increasing pump 105b fixedly installed outside the fixed seat 105a, a positioning piece 105c fixedly installed on the top of the gas increasing pump 105b, and a blowing plate 105d fixedly installed on the top of the positioning piece 105c.

[0037] During the winding process, the blowing assembly 105 blows gas to the film through the gas increasing pump 105b, the positioning piece 105c and the blowing plate 105d, thereby improving the success rate of the film adhering to the winding core and reducing the adhesion of dust and impurities on the film surface.

[0039] The servo motor 104b, the first rotating disc 104c and the second rotating disc 104d in the driving assembly 104 work cooperatively to realize automatic winding change operation, and when the first winding shaft 106 completes winding, the second winding shaft 107 can be automatically switched to continue winding without frequent manual intervention, thereby ensuring the continuity of the production line and improving the production efficiency.

[0040] In use, when winding work is performed, the film runs above the bearing frame 101 of the bearing mechanism 100, and when winding change is needed, the film cutting assembly 102 starts to work, the cylinder 102e on the supporting arm 102a acts to drive the rotating rod 102b and the cylinder 102c fixedly installed on the outer surface of the rotating rod 102b to rotate, and the limiting disc 102d on the outer surface of the cylinder 102c plays a limiting role to complete the film cutting operation.

[0041] Then, the driving motor 103b in the flying knife assembly 103 is started to drive the high-speed steel blade 103d to rotate through the connecting rod 103c on the output end, thereby cutting the film and ensuring the flatness of the film cutting position.

[0042] Meanwhile, the servo motor 104b in the driving assembly 104 works to drive the first rotating disc 104c to rotate, and the second rotating disc 104d is synchronously rotated through a belt wheel transmission, the first rotating disc 104c is fixedly connected with the end of the first winding shaft 106, and the second rotating disc 104d is fixedly connected with the end of the second winding shaft 107, so as to realize the switching of the winding shafts and complete the automatic roll changing;

[0043] In the winding process, the high-voltage electrostatic generator 203 of the electrostatic generating mechanism 200 works to make the electrostatic generating rod 204 at the bottom generate electrostatic on the surface of the film, so that the film has adsorption force, so that the film can be attached to the shaft center of the new roll, meanwhile, the air pressure pump 105b in the blowing assembly 105 works to blow air to the film through the positioning sheet 105c and the blowing plate 105d, so as to improve the success rate of the film attached to the roll core; when the winding is completed, the electrostatic eliminator 108 fixedly installed at the bottom of the horizontal plate 202 is started to instantaneously neutralize the electrostatic on the surface of the film.

[0044] In summary, the film breaking assembly 102, the flying knife assembly 103, the driving assembly 104 and the blowing assembly 105 in the bearing mechanism 100 and the electrostatic generating mechanism 200 are reasonably distributed and closely cooperate with each other, so that the overall structure of the device is compact, the operation is stable and reliable, and the electrostatic adsorption and winding work can be stably performed for a long time.
