Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0034] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0035] See also Figures 1-6 As shown, the utility model is a follower roller system for controlling precise retraction, including a mounting frame 1:

[0036] The mounting frame 1 is provided with a winding roller 2, a positioning assembly 3, a driving assembly 4 and a following assembly 5 respectively;

[0037] The outer surface of the winding roller 2 is rotatably arranged with the interior of the mounting frame 1 so that the winding roller 2 can wind the film;

[0038] The outer surface of the positioning component 3 is in contact with the outer surface of the winding roller 2, so that the positioning component 3 can detect the thickness of the film wound by the winding roller 2;

[0039] The output end of the driving component 4 is fixedly mounted to one side of the following component 5 , so that the driving component 4 drives the following component 5 to apply pressure to the winding roller 2 .

[0040] During use, the film is wound around the outer surface of the winding roller 2, and the outer surface of the film is fitted with the outer surface of the positioning component 3. Then, the driving component 4 is started to drive the following component 5 installed at the output end to move so that its outer surface is fitted with the outer surface of the film, so that it cooperates with the winding roller 2 to clamp the film, and the position of the following component 5 is adjusted according to the required pressure. As the winding roller 2 continuously winds the film, its diameter continues to increase, and in the process of its continuous expansion, it can squeeze the positioning component 3 and move it downward. When it moves, it can release an electrical signal to control the driving component 4 to drive the following component 5 to move a corresponding distance, so that the pressure exerted on the film by the following component 5 in cooperation with the winding roller 2 can be maintained, which is more convenient.

[0041] The utility model starts the driving component 4 to drive the following component 5 installed at the output end to move, so that its outer surface fits with the outer surface of the film, so that it cooperates with the winding roller 2 to clamp the film, and adjusts the position of the following component 5 according to the required pressure. As the winding roller 2 continuously rewinds the film, its diameter continues to increase, and in the process of its continuous expansion, it can squeeze the positioning component 3 and move it downward. When it moves, it can release an electrical signal to control the driving component 4 to drive the following component 5 to move a corresponding distance, so that the pressure exerted on the film by the following component 5 in cooperation with the winding roller 2 can be maintained, thereby avoiding wrinkles in the process of winding the film and ensuring the production quality of the film.

[0042] In one embodiment, the positioning assembly 3 includes a sliding groove 301, which is provided inside the mounting frame 1. A mounting block 302 is slidably provided inside the sliding groove 301. An abutting roller 303 is rotatably provided inside the mounting block 302. The outer surface of the abutting roller 303 is in contact with the outer surface of the winding roller 2. The bottom end of the mounting block 302 is fixedly connected to a first spring 304.

[0043] The positioning assembly 3 also includes a feedback plate 305 and a fixing frame 306 . One side of the feedback plate 305 is fixedly mounted to one side of the mounting frame 1 . One side of the fixing frame 306 is fixedly mounted to one side of the mounting block 302 . A distance detector 307 is fixedly mounted inside the fixing frame 306 .

[0044] As the winding roller 2 continuously winds the film, its diameter continues to increase, and in the process of its continuous expansion, it can squeeze the abutting roller 303 that is fitted on its outer surface to make it move downward, and thus can drive the mounting block 302 installed on the outer surface to move. When the mounting block 302 moves, it can compress the first spring 304 fixedly connected to the bottom end, and at the same time drive the fixing frame 306 installed on one side thereof to move, so that it drives the distance detector 307 installed inside to move. Since the feedback plate 305 is set on one side of the distance detector 307, when the distance detector 307 moves, it can cooperate with the feedback plate 305 to obtain the moving distance data, so that it releases an electrical signal to start the driving component 4 to drive the following component 5 to move, so that the following component 5 can always maintain pressure on the film.

[0045] In one embodiment, for the above-mentioned driving assembly 4, the driving assembly 4 includes a mounting plate 401, one side of the mounting plate 401 is fixedly mounted to one side of the mounting frame 1, and a motor 402 is fixedly mounted on one side of the mounting plate 401;

[0046] The driving assembly 4 further includes a rotating base 403, one side of which is fixedly mounted to one side of the mounting frame 1, and a threaded rod 404 is rotatably provided inside the rotating base 403, one end of which is fixedly connected to the output end of the motor 402;

[0047] The threaded surface of the threaded rod 404 is threadedly connected to a sliding block 405 , and one side of the sliding block 405 is fixedly mounted to one side of the tightening assembly 5 .

[0048] By starting the motor 402 to drive the threaded rod 404 fixedly connected to the output end to rotate, the threaded rod 404 rotates with the rotating seat 403 as the center of the circle. Since the threaded surface of the threaded rod 404 is threadedly connected to the sliding block 405, and one side of the sliding block 405 is fixedly installed with one side of the tightening component 5, when the threaded rod 404 rotates, it can cooperate with the sliding block 405 to drive the tightening component 5 to move, thereby facilitating the adjustment of its position.

[0049] In one embodiment, the following assembly 5 includes a mounting groove 501, which is provided inside the mounting frame 1. A limiting rod 502 is fixedly connected to the interior of the mounting groove 501. A push block 503 is slidably provided on the outer surface of the limiting rod 502. One side of the push block 503 is fixedly mounted to one side of the sliding block 405.

[0050] One side of the pushing block 503 is fixedly connected to a second spring 504, one end of the second spring 504 is fixedly connected to a support block 505, and a follower roller 506 is rotatably provided inside the support block 505, and the outer surface of the follower roller 506 is in contact with the outer surface of the winding roller 2.

[0051] When the sliding block 405 moves with the rotation of the threaded rod 404, it can drive the pushing block 503 installed on one side to move along the direction of the limit rod 502, so that the second spring 504 fixedly connected to one side moves, so that the second spring 504 drives the support block 505 fixedly connected at one end to move. Since the internal rotation of the support block 505 is provided with a follower roller 506, and the interior of the support block 505 is slidingly arranged with the outer surface of the limit rod 502, when the support block 505 moves, it can drive the follower roller 506 to move along the direction of the limit rod 502, and make its outer surface fit with the outer surface of the winding roller 2, so that when the winding roller 2 winds the film, it can cooperate with the follower roller 506 to press the film.

[0052] In one embodiment, for the above-mentioned installation groove 501, a limiting groove 6 is opened inside the installation groove 501, and two groups of limiting blocks 7 are slidingly arranged inside the limiting groove 6. The top ends of the two groups of limiting blocks 7 are fixedly connected to the bottom ends of the pushing block 503 and the supporting block 505 respectively.

[0053] When the pushing block 503 and the supporting block 505 move, they can drive the limit block 7 fixed at their bottom ends to move. Due to the sliding arrangement of the outer surface of the limit block 7 and the internal limiting groove 6, when the limit block 7 moves, it can move along the direction of the limiting groove 6, thereby improving the stability of the pushing block 503 and the supporting block 505 during movement.

[0054] Through the above technical solution, 1. By starting the driving component 4, the following component 5 installed at the output end is driven to move, so that its outer surface is in contact with the outer surface of the film, so that it cooperates with the winding roller 2 to clamp the film, and the position of the following component 5 is adjusted according to the required pressure. As the winding roller 2 continuously winds the film, its diameter continues to increase, and in the process of its continuous increase, it can squeeze the positioning component 3 and move it downward. When it moves, it can release an electrical signal to control the driving component 4 to drive the following component 5 to move a corresponding distance, so that the pressure exerted by the following component 5 on the film in cooperation with the winding roller 2 can be maintained, thereby avoiding wrinkles in the process of winding the film and ensuring the production quality of the film;

[0055] 2. The sliding block 405 is driven to move by the threaded rod 404, which can drive the pushing block 503 installed on one side to move along the direction of the limit rod 502, so that the second spring 504 fixedly connected to one side moves, so that the second spring 504 drives the support block 505 fixedly connected at one end to move. Since the internal rotation of the support block 505 is provided with a follower roller 506, and the interior of the support block 505 is slidingly arranged with the outer surface of the limit rod 502, when the support block 505 moves, it can drive the follower roller 506 to move along the direction of the limit rod 502, and make its outer surface fit with the outer surface of the winding roller 2, so that when the winding roller 2 winds the film, it can cooperate with the follower roller 506 to press the film.
