Technical Field
[0001] This utility model relates to the field of book wrapping film production technology, specifically a waste recycling device for book wrapping film production. Background Technology
[0002] Book wrapping film is a type of plastic film used to wrap books. Its main purpose is to protect the surface of books from pollution, moisture, friction, and other factors, while also extending the lifespan of the books. The production process of book wrapping film generates some waste, which needs to be recycled.
[0003] A waste recycling device for a plastic film production workshop, as disclosed in publication number CN 218256158 U, includes a recycling bin, a suction fan, a telescopic pipe, and a crushing assembly. The crushing assembly comprises a drive mechanism, two crushing shafts, two guide plates, and a placement box. When recycling is required, the drive mechanism is activated, causing the two crushing shafts to rotate in opposite directions. The suction fan is then activated, drawing the waste into the recycling bin through the telescopic pipe. After entering the recycling bin, the waste falls between the two crushing shafts, where their opposite rotation crushes the waste. The crushed waste then passes through the crushing shafts, passes through the guide plates, and falls into the placement box. This solves the problem that larger pieces of waste can easily clog the discharge pipe after entering the recycling bin through the telescopic pipe, causing inconvenience for workers during recycling.
[0004] However, the above-mentioned device still has some shortcomings in use. It has limited effect on crushing plastic film and can only crush it once, resulting in some plastic film not being crushed completely. Moreover, some dust and debris are generated during the crushing process and can easily escape, posing a health threat to users. Utility Model Content

The rotation of the first motor drives the crushing roller to initially crush the waste, which then falls onto the connecting plate. Simultaneously, the rotation of the first motor drives an eccentric wheel to continuously hammer the connecting plate, causing it to vibrate up and down continuously, thus initially crushing the waste. The shredded book wrapping film waste falls through the filter holes into the bottom receiving box. At the same time, some of the larger, incompletely shredded book wrapping film waste moves along the connecting plate to the empty trough and falls onto the crushing rollers. Then, the rotation of the second motor drives the two crushing rollers to rotate, further crushing the incompletely shredded book wrapping film waste, making the crushing effect better and facilitating subsequent recycling of the book wrapping film waste. During use, this device can crush the book wrapping film waste multiple times, resulting in a better crushing effect, while avoiding clogging of the filter holes and preventing dust and debris from escaping during the crushing process.

A rotating rod 12 is rotatably connected to one side wall of the crushing box 1. An eccentric wheel 13 is fixedly connected to one end of the rotating rod 12. The eccentric wheel 13 abuts against the connecting plate 7.
[0026] Example 2: The difference between this example and Example 1 is that, in this example, one end of the rotating rod 12 extends to the outside of the crushing box 1 and is fixedly sleeved with a drive sprocket 14, and one end of one of the crushing rollers 3 extends to the outside of the crushing box 1 and is fixedly sleeved with a driven sprocket 15. A chain 16 is connected between the drive sprocket 14 and the driven sprocket 15. A fixing plate 17 is fixedly connected to the side of the crushing box 1, and a first motor 18 is fixedly connected to the fixing plate 17. The output end of the first motor 18 is fixedly connected to the drive sprocket 14. The rotation of the first motor 18 can drive the crushing roller 3 to perform preliminary crushing and screening of the book wrapping film waste, which can avoid filter clogging.
[0027] Example 3: The difference between this example and Example 1 is that a second motor 19 is fixedly connected to the front of the crushing box 1. The output end of the second motor 19 extends into the interior of the crushing box 1 and is fixedly connected to one end of one of the crushing rollers 10.

[0031] In summary, this book wrapping film production waste recycling device works by feeding the book wrapping film waste into the feed hopper 2. The waste is then moved downwards by gravity, causing two baffles 22 to fall onto the crushing roller 3. The baffles 22 then close again under the force of the second spring 24. The rotation of the first motor 18 drives the crushing roller 3 to initially crush the waste, which then falls onto the connecting plate 7. Simultaneously, the rotation of the first motor 18 drives the eccentric wheel 13 to continuously hammer the connecting plate 7, causing it to vibrate up and down. This further crushes the book wrapping film waste on the connecting plate 7. The material falls through the filter holes into the bottom receiving box 25. At the same time, some of the larger, incompletely crushed book wrapping film waste moves along the connecting plate 7 to the empty trough 8 and falls from the empty trough 8 onto the crushing rollers 10. Then, the rotation of the second motor 19 drives the two crushing rollers 10 to rotate, which further crushes the incompletely crushed book wrapping film waste, making the crushing effect better and facilitating the subsequent recycling of the book wrapping film waste. When in use, this device can crush the book wrapping film waste multiple times, making the crushing effect better, while avoiding clogging of the filter holes and preventing some dust and flying debris from escaping during the crushing process.
