Description

Technical Field

[0001] This utility model relates to the field of PE protective film processing, and more specifically, to an automatic feeding machine for PE protective film. Background Technology

[0002] An automatic PE protective film feeder is a device used to automatically transport PE protective film to production equipment or processing steps. It effectively improves production efficiency and reduces the labor intensity and errors associated with manual feeding. PE protective film is typically used in roll form. The automatic feeder has an internal roller mechanism that mounts the protective film roll onto the roller. A motor drives the roller to rotate, releasing the protective film at a set speed and tension. Generally, a tension control system is also included, which uses sensors to detect the tension of the protective film and adjusts the motor speed to ensure smooth film transport.

[0003] Existing automatic PE protective film feeding machines use bolts to secure the PE film rolls. While this ensures a secure connection between the film rolls and the machine, replacing the film rolls requires operators to use tools to remove multiple bolts, impacting the efficiency of the replacement process. Solving these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-5 An automatic feeder for PE protective film includes a feeder body 1, a controller 2 and a driver 3. The controller 2 is fixedly connected to the outer wall of the feeder body 1, and the driver 3 is fixedly connected to the outer wall of the feeder body 1. A replacement component 4 is provided on the outer wall of the feeder body 1, and an auxiliary component 5 is provided on the outer wall of the replacement component 4.

[0031] Replacement component 4 includes a fixed plate 401, a support plate 402, a horizontal plate 403, a triangular plate 404, a movable plate 405, a rotating shaft 406, a slide rail 407, and a slider 408. The fixed plate 401 is fixedly connected to the outer wall of the feeding machine body 1. The support plate 402 is fixedly connected to the outer wall of the fixed plate 401. The horizontal plate 403 is fixedly connected to the top of the support plate 402. The triangular plate 404 is fixedly connected to the outer wall of the support plate 402. The outer wall of the triangular plate 404 abuts against the outer walls of the support plate 402 and the horizontal plate 403, respectively. The presence of the triangular plate 404 can strengthen the connection between the support plate 402 and the horizontal plate 403. The stabilizing effect between plates 403 is achieved by a movable plate 405 located at the top of the horizontal plate 403, with its bottom slidably connected to the top of the horizontal plate 403. The movable plate 405 can slide on the top of the horizontal plate 403. A rotating shaft 406 is rotatably connected to the outer wall of the movable plate 405. A slide rail 407 is opened inside the horizontal plate 403. A slider 408 is fixedly connected to the bottom of the movable plate 405, located inside the slide rail 407, and slidably connected to the inner wall of the slide rail 407. When the movable plate 405 moves, it can drive the slider 408 to move inside the slide rail 407.

[0032] By setting up a moving plate 405 and a rotating shaft 406, since the rotating shaft 406 is relatively short, when it is necessary to replace the PE film roll, the moving plate 405 is moved by sliding to separate the rotating shaft 406 from the PE film roll. At this time, the operator can remove the PE film roll by sliding and replace it, which solves the problem of low efficiency in replacing PE film rolls in existing automatic PE film feeding machines.

[0033] Auxiliary component 5 includes a bent tube 501, a slide rod 502, a pull rod 503, a pull ring 504, a stop plate 505, a first spring 506, a locking block 507, and a second spring 508. The bent tube 501 is fixedly connected to the outer wall of the horizontal plate 403, and an outer tube is fixedly connected to and communicates with the outer tube. The slide rod 502 is fixedly connected to the bottom of the movable plate 405, and one end of the slide rod 502 away from the movable plate 405 passes through the bent tube 501 and extends into the interior of the bent tube 501. The outer wall of the slide rod 502 is flush with the bent tube 501. A sliding connection is made through the inner wall of the tube 1. When the moving plate 405 moves, it can push the slide rod 502 to slide inside the bend 501. The pull rod 503 is located outside the bend 501. The pull ring 504 is fixedly connected to one end of the pull rod 503. The abutment plate 505 is fixedly connected to the end of the pull rod 503 away from the pull ring 504. The spring 506 is fixedly connected to the side where the abutment plate 505 is connected to the pull rod 503. The pull rod 503, the abutment plate 505, and the spring 506 are all located inside the outer tube. One end of the rod 503 penetrates the inner wall of the outer tube and extends to the outside of the outer tube. The outer wall of the rod 503 is slidably connected to the inner wall of the outer tube through which it is penetrated. The outer wall of the abutment plate 505 is slidably connected to the inner wall of the outer tube. The side of the spring 506 away from the abutment plate 505 is fixedly connected to the inner wall of the outer tube. The rod 503 can pull the abutment plate 505 to move inside the outer tube and apply pressure to the spring 506. The locking block 507 is fixedly connected to the outer wall of the abutment plate 505. The locking block 507 penetrates the outer tube and extends into the interior of the bend 501. The outer wall of the locking block 507 is slidably connected to the inner wall of the bent tube 501 through which it is penetrated. The first spring 506 can be moved by pushing the abutment plate 505, so that the abutment plate 505 pushes the locking block 507 to move into the inside of the bent tube 501. The second spring 508 is set inside the bent tube 501. The two sides of the second spring 508 are fixedly connected to the inner wall of the bent tube 501 and one end of the slide rod 502 extending into the inside of the bent tube 501, respectively. With the presence of the second spring 508, the moving plate 405 can be reset by pushing the slide rod 502.

[0034] By setting the locking block 507 and the second spring 508, when the moving plate 405 moves, it will apply pressure to the second spring 508 through the slide rod 502, and push the locking block 507 to slide inside the bend tube 501 until the slide rod 502 separates from the locking block 507. When the external force applied to the moving plate 405 stops, the locking block 507 will restrict the movement of the slide rod 502, so as to prevent the moving plate 405 from automatically resetting during the disassembly of the PE film roll by the operator.

[0035] The working principle of this automatic PE protective film feeder is as follows: When the PE film roll needs to be replaced, the moving plate 405 is moved by sliding, causing the rotating shaft 406 to separate from the roll. At the same time, when the moving plate 405 moves, it pushes the slide rod 502 to move inside the bent tube 501 and passes through the locking block 507. Then, the external force applied to the moving plate 405 stops, and the second spring 508 pushes the slide rod 502 to drive the moving plate 405 to reset, where it is blocked by the locking block 507. At this time, the PE film roll can be replaced. After the replacement is completed, the pull ring 504 is pulled, causing the pull ring 504 to drive the locking block 507 to separate from the slide rod 502 through the pull rod 503 and the abutment plate 505. At this time, the second spring 508 will push the slide rod 502 to move, causing the slide rod 502 to pull the moving plate 405 to reset, so that the rotating shaft 406 is engaged with the PE film roll, thus completing the fixation of the PE film roll.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
