Description

Technical Field

[0001] This application relates to the field of waste plastic treatment technology, and in particular to a compression mechanism for waste plastic treatment. Background Technology

[0002] With the widespread use of plastic products in daily life and industrial production, the amount of waste plastics generated is increasing daily. Waste plastics are characterized by their large volume and difficulty in degradation; if not properly handled, they not only occupy a large amount of land resources but also cause serious environmental pollution. Currently, the common method for handling waste plastics is recycling. In the recycling process, compressing and reducing the volume of waste plastics is a crucial step, as it reduces storage space and facilitates transportation and subsequent processing.

[0003] Existing waste plastic compression equipment often suffers from limited functionality. Many devices only perform compression, requiring manual handling of the shredded waste plastic to the compression mechanism, increasing labor intensity and reducing efficiency. Furthermore, while some devices integrate shredding and compression, they still have shortcomings in shredding effect, compression stability, and material transport smoothness. For example, the shredded plastic particles are uneven in size, affecting subsequent compression; blockages easily occur during material transport from the shredding to the compression mechanism; and insufficient compression force results in a still large volume of compressed waste plastic, leading to unsatisfactory volume reduction. Utility Model Content

[0013] Preferably, the top of the vertical pusher plate is provided with a horizontal filling plate on the side away from the receiving cavity, and the top of the receiving cavity is provided with a scraper on the side near the second frame. The scraper can scrape the waste plastic on the upper surface of the filling plate into the receiving cavity.

The second guide rod 27 is slidably connected to the second frame 12. The second frame 12 has through holes for the second guide rod 27 to slide. The vertical pusher plate 26 can cover the entire receiving cavity 9. The second telescopic component 25 can drive the vertical pusher plate 26 to move left and right along the length of the compression box 7, pushing the waste plastic in the receiving cavity 9 to the compression cavity 8, and cooperating with the vertical compression group 10 to compress the waste plastic, and also to discharge the compressed waste plastic.

A scraper 29 is fixedly to the top of the receiving cavity 9 near the second frame 12 by bolts.

[0035] The working process of the compression mechanism for waste plastic processing is as follows:

[0036] 1. Feed waste plastic into the feed hopper 4, and the waste plastic enters the crushing hopper 5.

[0037] 2. Start the drive motor 17. The drive motor 17 drives the drive wheel 18 to rotate, which drives the driven wheel 19 to rotate through the transmission belt 20.

[0039] 4. Activate the second telescopic component 25. The second telescopic component 25 drives the vertical pusher plate 26 to move towards the compression chamber 8, pushing the waste plastic in the receiving chamber 9 into the compression chamber 8. During the movement of the vertical pusher plate 26, the waste plastic on the upper surface of the filling plate 28 is scraped into the receiving chamber 9 by the scraper plate 29.

[0040] 5. The vertical pusher plate 26 is pushed between the compression chamber 8 and the receiving chamber 9 under the action of the second telescopic member 25, and the third telescopic member 31 is activated, which drives the gate 30 to move downward and close one side of the compression chamber 8.

[0041] 6. Activate the first telescopic component 22 to drive the horizontal compression plate 23 to move downward and compress the waste plastic in the compression chamber 8.

[0042] 7. After compression, the first telescopic component 22 drives the horizontal compression plate 23 to reset upward, the third telescopic component 31 drives the baffle 30 to reset upward, and the second telescopic component 25 drives the vertical pusher plate 26 to move towards the discharge plate 15, pushing the compressed waste plastic out of the discharge plate 15.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
