Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a novel granulating device for the production of fully degradable plastics. Background Art

[0002] In the process of plastic production, the adjusted plastic powder is usually granulated. Most granulating devices generally extrude columnar plastics through the extrusion holes on the extrusion head, and then cut them with blades to obtain formed plastic particles.

[0003] For example, the Chinese patent with the authorization announcement number: CN218803297U discloses a novel granulating device for the production of fully degradable plastics, belonging to the technical field of plastic production. It includes a conveying cylinder and a feed hopper arranged on one side of the upper end of the conveying cylinder. A spiral conveying rod is rotatably arranged inside the heat preservation conveying cylinder. A driving motor is arranged at one end of the conveying cylinder close to the feed hopper. A granulating assembly is arranged at one end of the conveying cylinder. First, the inner thread sleeve and the outer thread connecting rod are assembled so that the circular plate and the cutting knife are connected into one body. Then, the outer thread connecting rod is screwed into the inner thread hole. When adjusting the extrusion hole, the staff pulls one of the movable rods to make the T-shaped clamping seat disengage from the clamping groove. Then, the staff rotates the circular plate clockwise or counterclockwise to adjust the extrusion hole communicating with the inside of the conveying cylinder, avoiding the need to replace the extrusion head and solving the problem of complex replacement operation.

[0004] When feeding the plastic powder raw material, the above patent lacks a filtering and pulverizing mechanism to filter and pulverize the large raw materials doped in the plastic powder. If the large raw materials are not processed, the large raw materials are doped in the powder raw materials and directly enter the conveying cylinder. The large raw materials are usually not easily heated and melted, and are likely to cause blockage of the extrusion holes during the granulation process, affecting the normal operation of the granulating device, reducing the processing efficiency, and affecting the product quality.

[0031] Through the setting of the filter inclined plate 3, large raw materials doped in the plastic powder can be filtered and intercepted. The powder raw materials pass through the filter inclined plate 3 and enter the feeding cylinder 1 through the second feeding pipe 7 and the first feeding pipe 6 in sequence. The large raw materials intercepted by the filter inclined plate 3 are transported to the crushing box 4 through a plastic pipeline and are crushed by the crushing mechanism. The crushed raw materials enter the feeding cylinder 1 through the first feeding pipe 6. By filtering and crushing the large raw materials doped in the plastic powder, it is possible to prevent large raw materials from entering the feeding cylinder 1 and causing blockage of the extrusion holes 16, ensuring the normal operation of the granulating device and being beneficial to improving the granulating efficiency and product quality.

[0032] The crushing mechanism includes two first rotating shafts 8 rotatably installed on the inner wall of the crushing box 4. The other ends of the two first rotating shafts 8 rotatably penetrate through the crushing box 4 and are fixedly connected with gears 9. The outer surfaces of the two gears 9 are meshed with each other, and crushing rollers 10 are fixedly sleeved on the outer surfaces of the two first rotating shafts 8.

The output end of the driving motor 12 is fixedly connected to a second rotating shaft 13. A spiral conveyor blade 14 is fixedly sleeved on the outer surface of the second rotating shaft 13.

[0034] One end of the conveying cylinder 1 away from the driving motor 12 is provided with an extrusion head 15. A number of extrusion holes 16 are opened on the extrusion head 15.

And the heating plate 22 heats the raw materials to melt them. The melted raw materials are extruded through the extrusion holes 16. At the same time, the rotation of the second rotating shaft 13 drives the third rotating shaft 17 to rotate, and then drives the cutting blade 18 to rotate synchronously to cut the extruded plastic, and finally form columnar plastic particles.
