[0002] Ton bags are a relatively common type of waste in plastic film waste. In the process of ton bag treatment, in order to solve the problem of their large volume, ton bag crushing equipment is needed to reduce the volume and facilitate transportation and treatment.

[0003] Existing ton bag crushing equipment usually crushes ton bags through a pair of crushing drums. However, the shredded ton bag strips are easily wound around the crushing drums, resulting in the jamming of the crushing drums, and even burning out the motor, causing certain economic losses. Moreover, the daily maintenance and repair of the crushing equipment are crucial for ensuring its long-term stable operation. Regular maintenance can not only prevent small problems from evolving into big problems, but also significantly extend the service life of the equipment. However, the housing of existing ton bag crushing equipment is usually installed by bolts, which is not convenient for installation and disassembly, thus making the maintenance of the equipment relatively inconvenient.

One end of the pair of rotating cylinders 4 on the same side passes through the support plate 3 and is respectively connected with a first helical gear 12 and a second helical gear 13 that mesh with each other. The output end of the motor 11 is drivingly connected to the second helical gear 13.

[0028] Combined with the above structure, when the power assembly 6 is used, the second helical gear 13 is driven to rotate by the motor 11, so that the first helical gear 12 meshing with the second helical gear 13 rotates relatively, so that the pair of rotating cylinders 4 rotate relatively.

[0029] Combined with the attached Figure 1 , a protective cover 14 covering the power assembly 6 is installed at the upper end of the horizontal plate 1, which is convenient for protecting the power assembly 6.

[0030] Combined with the attached Figure 3 , on both sides inside the housing 7, there are sliding grooves 701 that cooperate with a pair of the support plates 3. Through grooves 702, through which the ends of a pair of the rotating cylinders 4 pass and are open at the lower end, are provided on the sliding grooves 701, which is convenient for the housing 7 to longitudinally move on a pair of support plates 3.

[0031] Combined with the attached Figure 3 , the scraping assembly 9 includes a connecting plate 15 screwed to the inner side wall of the housing 7.

The crushed ton bags are discharged through the discharge port 101 to achieve the crushing of ton bags. Through a number of scraping plates 16 on the scraping assembly 9 that are in contact with the curved surface of the rotating cylinder 4 and are located between adjacent crushing teeth 5, it is convenient to scrape off the shredded ton bag strips wound around the crushing teeth 5 to prevent the rotating cylinder 4 from getting stuck. When the device needs to be repaired, rotate the knob 21 of the positioning assembly 10 to make the threaded rod 20 rotate. The moving plate 19 cannot rotate through the cooperation of the positioning rod 18 and the second support plate 17, so that the moving plate 19 drives the positioning rod 18 to move out of the positioning hole 703, and then the housing 7 can be taken out for easy repair.
