Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle production, and in particular relates to a heating plasticizing device used for plastic particle production. Background Art

[0002] Plastic granules are a kind of granular semi-finished products made from plastic raw materials or synthetic resins. They can be used to produce various plastic products or composite materials. There are many types of plastic granules. According to different properties and uses, they can be divided into three categories: general-purpose plastics, engineering plastics and special plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, etc. They are characterized by low cost, easy processing and wide application. Engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, polycarbonate, etc. They have the characteristics of high strength, high heat resistance and high corrosion resistance, and are often used to manufacture mechanical parts, electronic components, etc. Special plastics include thermosetting plastics, functional polymer plastics, etc. They have special physical or chemical properties and are often used to manufacture artificial organs, aerospace equipment, etc.

[0003] In the process of producing plastic particles, plastic particles of different products often require unique modified raw materials to achieve specific physical or chemical properties. When converting the production of plastic particles of different products, in order to prevent the modified raw materials of the current batch from reacting with the residual substances of the previous batch from undesirable chemical reactions. After completing the processing of the same batch of products, the heating and plasticizing device needs to be cleaned to ensure the purity and performance of the plastic particle products. Publication No. CN211416153U discloses a heating and plasticizing device for the production of engineering plastics. The raw material enters the heating cylinder through the feed pipe, and the driving motor drives the feeding auger to feed the material.

A driving motor 8 is arranged on the outer surface of the mounting plate 7, and the output shaft of the driving motor 8 passes through the mounting plate 7 and is connected to the screw conveyor 11. Specifically, a threaded hole is arranged on the side wall of the box body 1 relative to the mounting plate 7, and a fastener 14 matching the threaded hole is arranged on the mounting plate 7. The fastener 14 is a bolt or a screw, and the mounting plate 7 is detachably connected to the box body 1 through the fastener 14 and the threaded hole. It is convenient to disassemble and assemble the mounting plate 7, the driving motor 8 and the screw conveyor 11 through the fastener 14, so as to facilitate the cleaning and maintenance of the inside of the box body 1 and the screw conveyor 11.

[0025] Furthermore, a guide plate 17 is provided in the discharge pipe 6 through a rotating rod 15, and a torsion spring 16 for resetting the guide plate 17 is sleeved on the rotating rod 15. Specifically, one end of the torsion spring 16 is connected to the guide surface of the guide plate 17, and the other end is connected to the inner surface of the discharge pipe 6. The guide plate 17 guides the material when the material is discharged, so as to avoid splashing of the material when the material is discharged.

[0026] Preferably, the angle between the material guiding surface of the material guiding plate 17 and the horizontal plane is an acute angle.

[0027] Furthermore, a bracket 9 is provided on the lower end surface of the mounting plate 7, and a universal wheel 10 is provided at the lower end of the bracket 9.
