[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1: Reference Figure 1-4 The insulation pipe extrusion device includes a body 1, a connecting shell 3 is fixedly installed on the body 1, and a hopper 2 is fixedly installed on the upper end of the connecting shell 3. The hopper 2 is a hopper structure in the prior art. The hopper 2 is used to provide materials for the body 1. The staff needs to put the granular materials into the hopper 2. The granular materials at the bottom of the hopper 2 will enter the body 1 through the connecting shell 3.

[0018] A rotating shaft 10 is installed on the top of the inner side of the feed hopper 2 through the rotation of the motor, and the rotating shaft 10 can be driven to rotate by the motor. A connecting rod 11 is fixedly installed on the outer side of the end of the rotating shaft 10, and a scraper 12 is fixedly installed on the end of the connecting rod 11. The rotation of the rotating shaft 10 can drive the scraper 12 to rotate through the connecting rod 11. The scraper 12 is tilted and fits the inner wall of the feed hopper 2. The rotation of the scraper 12 can mix the materials and prevent the materials from adhering to the inner wall surface of the feed hopper 2. A feeding rod 13 is fixedly installed at the lower end of the rotating shaft 10. The feeding rod 13 is located in the connecting shell 3. The feeding rod 13 is spiral. The rotating shaft 10 and the feeding rod 13 are coaxially arranged. The rotation of the rotating shaft 10 can drive the feeding rod 13 to rotate. The bottom of the feeding rod 13 extends into the body 1 and is located above the conveying part 6. When the feeding rod 13 rotates, it can transport the materials that fall into the connecting shell 3 downward, and the materials will fall above the conveying part 6. The rotation of the conveying part 6 can drive the materials to move.

[0019] The feeding rod 13 is located in the connecting shell 3, and the feeding rod 13 occupies the space inside the connecting shell 3, so that the material can only pass through the connecting shell 3 by being transported by the feeding rod 13. The feeding rod 13 rotates at a uniform speed to drive the material to fall evenly, and can ensure that the same amount of material is transported per unit time. Moreover, the scraper 12 can fully stir the material in the hopper 2, which can ensure that the material can continuously fall downward, and prevent the material from being blocked in the hopper 2. At least two scrapers 12 are provided, and the heights are different. The scraper 12 located at the top can fully stir the material in the hopper 2 to prevent uneven mixing of the material, and the scraper 12 located at the bottom can fully stir the material at the bottom of the hopper 2 to prevent the material from being blocked.

[0020] The body 1 is provided with a screw 4 for rotation, the end of the screw 4 is connected to an external power device, the external power device is a motor, and the screw 4 can be driven to rotate by the external power device. The screw 4 includes a kneading part 5 and a conveying part 6, the kneading part 5 is fixedly connected to the conveying part 6, the conveying part 6 is spiral, and the kneading part 5 has crushing pieces arranged in a circular array, as shown in the attached Figure 3 As shown, the conveying part 6 is used to convey the material, and the kneading part 5 is used to mix the material. The conveying part 6 and the kneading part 5 are arranged alternately, and the material can be stirred and mixed in the process of conveying the material. The body 1 generates high temperature through electric heating to melt the raw materials. There is a gap between the screw 4 and the inner wall of the body 1. In the process of conveying the material, the molten material can be plasticized by continuously squeezing the material, and extruded from the mold mouth through the diverter plate at the end of the body 1.

[0021] A diverter plate 8 is fixedly installed on the inner side of the end of the body 1. A through hole is opened inside the diverter plate 8 for the molten material to pass through. A filter screen 7 is fixedly installed on the surface of the diverter plate 8 close to the inner side of the body 1. The diverter plate 8 supports the filter screen 7. The two can effectively prevent impurities in the molten material from passing through. A tube extrusion die head 9 is fixedly installed on the end of the body 1 and on the outside of the diverter plate 8. The tube extrusion die head 9 is a structure that can filter materials in the prior art, and finally the material can be extruded through the tube extrusion die head 9.

[0022] Working principle: During the operation of the thermal insulation pipe extrusion device, the granular material is put into the hopper 2, and the rotating shaft 10 is driven to rotate. The rotating shaft 10 drives the scraper 12 to rotate through the connecting rod 11. The rotation of the scraper 12 can stir and mix the material in the hopper 2, and can prevent the material from being blocked or adhering to the surface of the hopper wall, and the material can fall down smoothly. The rotation of the rotating shaft 10 will also drive the feeding rod 13 to rotate. The rotation of the feeding rod 13 can uniformly transport the material entering the connecting shell 3 in equal amounts, so that the material falls to the conveying part 6. By driving the conveying part 6 and the kneading part 5 to rotate, the material can be mixed again during the material conveying process. The high temperature generated by the electric heating of the inner wall of the body 1 can melt the raw materials, and the material will be extruded when being transported in the body 1, which can plasticize the molten material. Then, the material will pass through the filter screen 7 and the diverter plate 8, which can effectively prevent impurities in the molten material from passing through, and finally the material is extruded through the tube extrusion die 9.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
