Description

Technical Field

[0001] The utility model relates to the technical field of plastic molding, in particular to a composite thermoplastic elastomer plastic extruder. Background Art

[0002] Composite thermoplastic elastomer refers to a type of elastomer that has the elasticity of rubber at room temperature and can be plasticized and formed at high temperature. It can be produced by injection molding, extrusion, blow molding and other processing methods. It has the characteristics of environmental protection, non-toxicity, comfortable feel and exquisite appearance. Plastic extruders are now mostly used to complete the extrusion processing. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a composite thermoplastic elastomer plastic extruder with publication number: CN212736990U, comprising a machine body, a molding device, a machine head, a screw barrel, a hopper, a front heat dissipation frame, a front heat dissipation net, a side heat dissipation frame, a side heat dissipation net, a heat dissipation chamber, a positioning rod, a positioning groove, a return spring, a rotating groove, a support rod and a support groove. The heat dissipation panel of a conventional composite thermoplastic elastomer plastic extruder is generally a single-sided structure with limited heat dissipation effect. In particular, when the machine is used for a long time, heat is easily accumulated inside the machine, and it is necessary to increase the heat dissipation area to improve the heat dissipation effect of the machine. In this embodiment, a plurality of side heat dissipation nets are added behind the single-sided front heat dissipation frame, and then the side heat dissipation nets are pulled out of the heat dissipation chamber, so that the heat dissipation area can be greatly increased, thereby improving the heat dissipation effect. The conventional heat dissipation surface only has the front heat dissipation net, while in this embodiment In the embodiment, after the front heat dissipation frame is pulled outward, a part of space is left on the upper and lower surfaces and left and right surfaces behind the front heat dissipation frame, and this part of space can be used for heat dissipation, that is, the heat dissipation area is increased. However, this part of space lacks obstructions and is easy to enter debris. Therefore, adding a side heat dissipation net in this part of space will not affect the heat dissipation effect and can prevent foreign objects from entering the heat dissipation chamber at the same time. After the front heat dissipation frame is pulled outward, the support rod is rotated to a state perpendicular to the body, and the rear end of the support rod is inserted into the support groove, so that the front heat dissipation frame can be supported by the support rod. When the traditional heat dissipation effect can meet the use requirements, the side heat dissipation net can be stored in the heat dissipation chamber. At this time, the support rod is first rotated again to a horizontal state with the front heat dissipation frame, and the reset spring drives the side heat dissipation net to automatically move into the heat dissipation chamber for storage through elastic reset.

[0004] In the above utility model, the molded composite thermoplastic elastomer will enter the interior of the body. There is no heat dissipation structure. Even if the heat dissipation area is increased by the front heat dissipation net and the side heat dissipation net, the heat inside the body is difficult to dissipate quickly, and thus the heat dissipation efficiency of the composite thermoplastic elastomer molded by the composite thermoplastic elastomer plastic extruder is average.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a composite thermoplastic elastomer plastic extruder, which has the following beneficial effects:

[0018] (1) The utility model adopts a rotating cylinder.

Then, the control panel is used to make the driving motor and the electric gate valve work. The first sealed bearing is used.

[0035] Working principle:

[0036] When the composite thermoplastic elastomer plastic extruder is actually used, the operator opens and closes the control valve 11 by hand, and the raw materials in the feed hopper 10 will enter the interior of the conveying cylinder 1, and then use the control panel to make the drive motor 5 and the electric gate valve 8 work. Using the first sealed bearing 3, when the drive motor 5 is working, its output end drives the auger 12 to rotate through the connecting shaft 6. The rotating auger 12 can push the raw materials, so that the raw materials are extruded through the discharge hopper 7 into the interior of the external molding device. One end of the two sets of connecting hoses 19 can be connected with the output end of the molding device. The molded composite thermoplastic elastomer will enter the interior of the rotating cylinder 2 through the two sets of connecting pipes 15.

The rotating fan blades 29 can push air to the rotating cylinder 2, and the multiple groups of filter covers 28 play a role in covering and protecting the multiple groups of fan blades 29. The third pulley 32 drives the rotating cylinder 2 to rotate through a group of connecting pipes 15 on the right side.
