[0002] In plastic processing, it is also called extrusion molding or extrusion. In rubber processing, it is also called extrusion. It refers to a processing method in which materials are continuously made into various cross-section products or semi-products through the action between the barrel and the screw of an extruder and then through the die head. However, in the prior art, when plastic is extruded from the barrel, the plastic is prone to cooling and plasticization, which may cause the screw to become blocked when pushing the plastic, thus affecting the plastic molding. Therefore, a plastic extrusion processing device is proposed. Content of the Utility Model

One side of the gear transmission box is provided with a motor, and the motor is in driving connection with the gear transmission box. The motor is in transmission connection with the second transmission shaft through the gear transmission box. Thus, the screw is driven to rotate inside the barrel by the motor. A heating sleeve is sleeved outside the barrel, and the inner part of the heating sleeve is in mutual fit with the outer barrel wall of the barrel. A hot air blower is vertically arranged at the bottom of the heating sleeve.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-4 , in the embodiment of the present invention, a plastic extrusion processing device includes a workbench 1 and a support frame 2 arranged on one side of the workbench 1. A material cylinder 8 is horizontally arranged at the top of the support frame 2, and a screw 15 is horizontally arranged inside the material cylinder 8. One side of the top of the workbench 1 is provided with a gear transmission box 3, and a second transmission shaft 13 is driven on one side of the gear transmission box 3. The second transmission shaft 13 is in transmission connection with the screw 15. A motor 4 is arranged on one side of the gear transmission box 3, and the motor 4 is in driving connection with the gear transmission box 3. The motor 4 is in transmission connection with the second transmission shaft 13 through the gear transmission box 3. Thus, the screw 15 is driven to rotate inside the material cylinder 8 by the motor 4. A heating sleeve 6 is sleeved outside the material cylinder, and the inside of the heating sleeve 6 is in close fit with the outer barrel wall of the material cylinder 8. A hot air blower 7 is vertically arranged at the bottom of the heating sleeve 6. When the liquefied rubber material enters the inside of the material cylinder 8, the motor 4 and the gear transmission box 3 are in transmission cooperation, so as to drive the second transmission shaft 13 to drive the screw 15 to push the rubber material inside the material cylinder 8. At this time, the hot air blower 7 conveys hot air to the heating sleeve 6, so that the heating sleeve 6 generates heat and continuously conducts the heat to the material cylinder 8. Thus, the rubber material inside the material cylinder 8 is heated and plasticized while being pushed forward by the screw 15 and extruded from the other end of the material cylinder 8, so as to ensure that the rubber material will not be easily cooled and plasticized and stuck inside the material cylinder 8 when being extruded from the inside of the material cylinder 8.
[0019] A first transmission shaft 9 is horizontally driven inside one side of the gear transmission box 3. The first transmission shaft 9 is in driving connection with the motor 4 and in transmission connection with the second transmission shaft 13. Thus, when the motor 4 drives the first transmission shaft 9 to rotate, the second transmission shaft 13 is simultaneously driven to rotate.
[0020] On one side of the first transmission shaft 9, a first gear 10 is coaxially driven. On one side of the first gear 10, a gear shaft 11 is provided. The gear shaft 11 is rotatably arranged inside the gear transmission box 3. At one end of the gear shaft 11, a second gear 12 is coaxially driven. The first gear 10 meshes with the second gear 12. On one side of the gear shaft 11, a third gear 14 is provided. The third gear 14 is coaxially driven and connected to the second transmission shaft 13. The third gear 14 meshes with the gear shaft 11. Thus, through the transmission cooperation between the first transmission shaft 9 and the gear shaft 11, the second transmission shaft 13 and the connecting screw 15 are driven to rotate.
[0021] The material cylinder 8 is provided with a feeding funnel 5. The feeding funnel 5 is vertically located at the top of the material cylinder 8. The feeding funnel 5 is in through connection with the material cylinder 8. Thus, the liquefied rubber material flows into the interior of the material cylinder 8 through the feeding funnel 5.
[0022] On one side of the material cylinder 8, a discharge port 16 is formed. Vertically arranged on one side of the discharge port 16 is a grid screen (not shown in the figure). The grid screen and the discharge port 16 are in the same vertical plane. Thus, the plastic in the material cylinder 8 can be separated and extruded into plastic strips through the grid screen and the discharge port 16.
[0023] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments. Without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
