Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of plastic bag degradation, and specifically to an automatic loading and unloading device for environmental protection plastic bag degradation. Background Technique
[0002] Plastic bag degradation refers to the process in which plastic bags gradually decompose into small molecule substances under natural or artificial conditions, mainly including three main ways: photodegradation, biodegradation, and oxidative degradation. Among them, photodegradation relies on ultraviolet radiation to break the plastic molecular chains; biodegradation requires the participation of specific microorganisms, such as the decomposition process of compostable plastic bags; oxidative degradation accelerates the decomposition of plastics by adding pro-oxidants. However, traditional polyethylene (PE) plastic bags still take hundreds of years to completely degrade in the natural environment, which highlights the necessity of reducing use, promoting environmental protection alternatives, and improving the recycling system, rather than simply relying on degradation technology.
[0003] Currently, in the actual operation of plastic bag degradation treatment, there are often problems with imperfect treatment processes. For example, in the feeding link, a large number of plastic bags are usually directly concentrated and put in, lacking necessary pre-treatment processes. The recycled plastic bags are often attached with pollutants such as oil stains and food residues. These impurities will not only interfere with the degradation process but also may reduce the final treatment effect, so improvements are needed. Summary of the Invention

The output end of the water supply pump 8 is fixedly communicated with a water delivery pipe 9. The other end of the water delivery pipe 9 is connected to the input end of the sprayer 7. A number of first water leakage holes are arranged on the conveyor belt 5, and a number of overflow ports 11 are opened on the device main body 1. Specifically, water for cleaning can be stored in the water storage area. The provided water supply pump 8 can extract water and convey the water to the sprayer 7 through the water delivery pipe 9 for spraying outward to flush the plastic bag fragments on the conveyor belt 5. A dryer 12 is fixedly connected inside the device main body 1. Both the sprayer 7 and the dryer 12 are arranged above the conveyor belt 5.

[0027] Inside the conveyor belt 5, there is a vibrating plate 14. A number of through holes are provided on the vibrating plate 14. Two groups of springs 16 are fixedly connected to the lower end surface of the vibrating plate 14. The bottom end of each spring 16 is fixedly connected to a connecting seat 15.

[0031] Working principle: After the device is started, the staff puts the plastic bag to be processed into the device main body 1 through the feed hopper 2. First, two crushing rollers 3 driven by the drive box 4 rotate to crush the plastic bag and decompose it into small pieces. The crushed pieces then fall onto the conveyor belt 5. During the conveying process, the water supply pump 8 transports the water in the water storage area to the sprayer 7 through the water supply pipe 9, and the pieces can be sprayed and washed. The waste water after washing flows back to the water storage area through the first water leakage holes on the conveyor belt 5 and the overflow port 11 on the device main body 1 for recycling. At the same time, driven by the drive motor 6, the movement of the conveyor belt 5 drives the first gear 18 through the second gear 19, causing the cam roller 17 to rotate, and then pushing the vibration plate 14 to vibrate with the cooperation of the spring 16 to promote the dehydration of the pieces. Subsequently, the dryer 12 dries the pieces, and finally the processed plastic pieces are discharged through the discharge hopper 13 and enter the subsequent degradation process.
