Anti-winding film type shredder

Abstract

This utility model discloses an anti-tangling film shredder, including a machine body. In this utility model, a film bag is added to the feed inlet. A first motor on the front surface of the feed inlet is activated, driving a rotating rod to rotate. Simultaneously, the rotating rod drives the dispersing teeth on the rotating rod to rotate, thus tucking the film bag into the machine body. Then, a second motor on the front surface of the machine body is activated, driving a shredding roller to rotate, thereby shredding the film bag. The use of an anti-static guide plate on the inner wall of the feed inlet prevents the film bag from directly rubbing against the inner wall and generating static electricity, thus preventing the film bag from adhering to the feed inlet. The use of the first motor, rotating rod, and dispersing teeth ensures the film bag is tucked into the machine body, resulting in more thorough feeding and improved working efficiency.

Description

Technical Field

[0001] This utility model relates to the field of shredder technology, and in particular to an anti-tangling film shredder. Background Technology

[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products are taking up an increasingly large share of the market, especially composite plastic flexible packaging, which is widely used in the food, pharmaceutical, and chemical industries. Food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, retortable food packaging, and fast food packaging. Since plastic film needs to be shredded during recycling, a film shredder is required to process it.

[0003] The existing Chinese patent with publication number CN215612128U discloses a biaxial shredder for plastic woven bag film. The existing technical solution has the following defects: Although the above technical solution can avoid workers from directly contacting the first blade fixedly installed on the outer circular wall of the first and second cutter shafts through the hopper, thus preventing accidents and protecting workers, when the film bag is added to the equipment through the feeding hopper, the film bag will come into frictional contact with the inner wall of the hopper, which can easily generate static electricity. This can cause the film bag to adhere to the hopper, resulting in incomplete feeding and reducing its working efficiency. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an anti-tangling film shredder, which allows film bags to enter the equipment, prevents the film bags from adhering to the inner wall of the feed inlet, ensures more thorough material feeding, and has high working efficiency, thereby solving the problems mentioned in the background technology.

[0005] (II) Technical Solution To achieve the above objectives, the present invention adopts the following technical solution: an anti-tangling film shredder, comprising a body, a feed inlet located at the center of the top surface of the body, and an anti-static guide plate on the inner wall of the feed inlet; a first motor mounted on the front surface of the feed inlet, with the output end of the first motor passing through the feed inlet and fixedly connected to a rotating rod; the rotating rod having disintegrating teeth located inside the feed inlet; shredding rollers mounted on both sides of the inner wall of the body; and a second motor mounted on both sides of the front surface of the body, the output end of the second motor being connected to the shredding rollers.

A limiting rod 17 is provided through the connecting block 14 in the groove 15, and a spring 16 is sleeved on the outer surface of the limiting rod 17 on one side of the connecting block 14. When the film bag is added into the feed port 2, the first motor 18 on the front surface of the feed port 2 is turned on. The first motor 18 drives the rotating rod 8 to rotate. At the same time, the rotating rod 8 drives the dispersing teeth 7 on the rotating rod 8 to rotate, which can twist the film bag in the feed port 2 into the machine body 1. Then, by turning on the second motor 19 on the front surface of the machine body 1, the second motor 19 drives the shredding roller 9 to rotate, which can shred the film bag that has entered the machine body 1. The use of the anti-static guide plate 3 on the inner wall of the feed port 2 can prevent the film bag from directly contacting the inner wall of the feed port 2 and generating static electricity, thereby preventing the film bag from adhering to the feed port 2. With the use of the first motor 18, the rotating rod 8 and the dispersing teeth 7, the film bag can be twisted into the machine body 1, so that the feeding can be more thorough and improve its working efficiency.

[0020] In one embodiment, a collection box 10 is provided on the bottom upper surface of the body 1, and a handle 21 is provided on the front surface of the collection box 10. The collection box 10 is movably connected to the body 1, and the shredded film bag can be collected by using the collection box 10.

[0021] In one embodiment, the front surface of the body 1 is provided with a box door 20 on both sides below the second motor 19, and the box door 20 is hinged to the body 1 by a hinge, wherein the collection box 10 can be taken out by opening the box door 20.

[0022] In one embodiment, a connecting rod 12 is provided through the connecting block 14 in the through groove 13. The connecting block 14 and the connecting rod 12 are slidably connected. The connecting rod 12 can limit the position of the connecting block 14, thereby facilitating the stability of the connecting block 14 during movement.

[0023] In one embodiment, the connecting block 14 matches the groove 15 and is slidably connected to the limiting rod 17. Through the use of the groove 15, the limiting rod 17 and the spring 16, the impact of the shredding roller 9 on the cleaning brush 6 during operation can be absorbed, thereby reducing the impact force of the shredding roller 9 on the cleaning brush 6 during operation, which can reduce the wear of the cleaning brush 6 during use and help extend the service life of the cleaning brush 6.

[0024] In one embodiment, two cleaning brushes 6 are provided, and the two cleaning brushes 6 are evenly distributed on both sides of the inner wall of the machine body 1. The cleaning brushes 6 are matched with the shredding roller 9. By opening the electric telescopic rod 5 on one side surface of the connecting frame 4, the electric telescopic rod 5 drives the connecting block 14 to move. While the connecting block 14 is moving, the cleaning brushes 6 are also moved. When the cleaning brushes 6 come into contact with the shredding roller 9 in the machine body 1, the film bag wrapped on the shredding roller 9 can be cleaned, preventing the film bag from getting wrapped on the shredding roller 9 during the processing, thereby facilitating the normal operation of the shredding roller 9.

[0025] In one embodiment, the bottom surface of the body 1 is provided with support legs 11 on both sides. There are multiple support legs 11, and the multiple support legs 11 are evenly distributed in pairs on both sides of the bottom surface of the body 1. The support legs 11 are fixedly welded to the body 1. The support legs 11 support the body 1, which helps to improve the stability of the body 1.

[0026] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0027] Working principle: In operation, the film bag is inserted into the feed inlet 2. The first motor 18 on the front surface of the feed inlet 2 is turned on, driving the rotating rod 8 to rotate. Simultaneously, the rotating rod 8 drives the shredding teeth 7 on it to rotate, thus shredding the film bag in the feed inlet 2 into the machine body 1. Then, the second motor 19 on the front surface of the machine body 1 is turned on, driving the shredding roller 9 to rotate, thus shredding the film bag entering the machine body 1. The use of the anti-static guide plate 3 on the inner wall of the feed inlet 2 prevents the film bag from directly rubbing against the inner wall of the feed inlet 2 and generating static electricity, thereby preventing the film bag from adhering to the feed inlet 2. The combined action of the first motor 18, rotating rod 8, and shredding teeth 7 ensures the film bag is shredded into the machine body 1, resulting in a more efficient shredding process. Thorough feeding improves work efficiency. By opening the electric telescopic rod 5 on one side of the connecting frame 4, the electric telescopic rod 5 moves the connecting block 14, which in turn moves the cleaning brush 6. When the cleaning brush 6 comes into contact with the shredding roller 9 in the machine body 1, the film bag wrapped around the shredding roller 9 can be cleaned, preventing the film bag from getting tangled on the shredding roller 9 during processing. This helps maintain the normal operation of the shredding roller 9. The use of the groove 15, the limiting rod 17, and the spring 16 can absorb the impact of the shredding roller 9 on the cleaning brush 6 during operation, reducing the impact force of the shredding roller 9 on the cleaning brush 6 during operation. This reduces the wear of the cleaning brush 6 during use and helps extend its service life.
