[0004] In existing extruders, when processing wound structured wall tubes, the raw material is added into the feed hopper. However, it is not easy to scrape off the raw material adhering to the inner wall of the feed hopper after it is added. As a result, in subsequent processing, a lot of raw material is easily wasted due to the adhering material on the inner wall of the feed hopper.

[0005] Therefore, we propose an extruder for anti-clogging spiral wound structured wall pipes to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an anti-clogging extruder for spiral wound structured wall tubes, in order to solve the problem mentioned in the background art that existing extruders on the market, when processing spiral wound structured wall tubes, do not easily scrape off the material adhering to the inner wall of the feed hopper after the raw material is added into the feed hopper, resulting in waste due to the large amount of raw material adhering to the inner wall of the feed hopper during subsequent processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an extruder for anti-clogging spiral wound structure wall pipe, comprising an extruder body and a feeding hopper installed on the extruder body, wherein a feeding port for feeding raw materials is installed on the side of the feeding hopper, and a movable cleaning component is installed in the middle of the feeding hopper, and the movable cleaning component is used to agitate the raw materials inside the feeding hopper and scrape off the raw materials adhering to the inner wall of the feeding hopper.

A cleaning scraper is fixed on the transmission rod, and an agitator is connected to the middle of the transmission rod. A movable column is inserted into the middle of the transmission rod, and a limit rod is fixed at the lower end of the movable column. The limit rod is inserted into a snap-fit ​​plate fixed inside the feeding hopper.

[0009] By adopting the above technical solution, the cleaning scraper can be driven to rotate synchronously by the transmission rod through the activation of the servo motor.

The moving column and the transmission rod are reciprocating threaded connections.

[0013] By adopting the above technical solution, and using a limiting rod with a rectangular cross-section, it is possible to prevent the moving column from rotating synchronously with the transmission rod.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] Please see Figures 1-8 Existing extruders, when processing wound structured wall tubes, add raw materials into a feed hopper. However, it's difficult to scrape off the raw materials adhering to the inner wall of the feed hopper after the materials are added, leading to waste during subsequent processing due to excessive material buildup. To address this problem, this embodiment discloses the following technical content: an anti-clogging extruder for wound structured wall tubes, including an extruder body 1 and a feed hopper 2 mounted on the extruder body 1. The feed hopper 2 has a material feeding port 3 installed on its side, and a movable cleaning component 4 installed in the middle of the feed hopper 2 for cleaning the feed material. The moving cleaning component 4 includes a servo motor 401 for stirring the raw materials inside the hopper 2 and scraping off the raw materials adhering to the inner wall of the feeding hopper 2. The output end of the servo motor 401 is equipped with a transmission rod 402. A cleaning scraper 403 is fixed on the transmission rod 402. An agitator 404 is connected to the middle of the transmission rod 402. A moving column 405 is inserted into the middle of the transmission rod 402. A limit rod 406 is fixed at the lower end of the moving column 405. The limit rod 406 is inserted into a snap-fit ​​plate 407 fixed inside the feeding hopper 2. The cleaning scraper 403 is symmetrically arranged about the transverse central axis of the transmission rod 402. The cleaning scraper 403 and the inner wall of the feeding hopper 2 are in close contact with each other.

[0035] When it is necessary to extrude the spiral wound structure wall tube, the raw material is added into the inside of the feeding hopper 2 through the feeding port 3. The added raw material enters the inside of the extruder body 1, thereby carrying out normal extrusion production. The extruder body 1 is existing equipment, and the specific extrusion method is also the same as the existing technology.

[0036] After the raw materials are added into the hopper 2, the servo motor 401 is turned on. The servo motor 401 causes the transmission rod 402 to rotate. The rotation of the transmission rod 402 causes the cleaning scraper 403 to rotate synchronously. The rotation of the cleaning scraper 403 can scrape off the raw materials adhering to the inner wall of the hopper 2. At the same time, the rotation of the transmission rod 402 can drive the agitator 404 to rotate. The rotation of the agitator 404 can agitate the raw materials inside the hopper 2, improve the flowability of the raw materials inside the hopper 2, and prevent blockage.

[0037] The outer wall of the limiting rod 406 at the lower end of the moving column 405 and the inner wall of the middle part of the snap plate 407 are in contact with each other, and the limiting rod 406 with a rectangular cross-section can move on the snap plate 407. The moving column 405 and the transmission rod 402 are reciprocating threaded connections.

[0038] To further improve the agitation effect of the raw materials inside the feeding hopper 2, since the moving column 405 and the transmission rod 402 are connected by a reciprocating thread, the reciprocating thread can be referred to as the thread on the surface of the reciprocating screw. At the same time, the limiting rod 406 at the bottom of the moving column 405 can only move on the snap plate 407. When the transmission rod 402 rotates, the threaded moving column 405 can move up and down reciprocally. The up and down reciprocating movement of the moving column 405 can further improve the agitation effect of the raw materials inside the feeding hopper 2.

[0039] Example 2:

[0040] The technical content disclosed in this embodiment differs from that in Embodiment 1 above in that: the movable cleaning component 4 includes a cylinder 411, and a connecting column 412 is fixed to the telescopic end of the cylinder 411. A cleaning frame 413 is provided on the outside of the connecting column 412, and the upper middle part of the cleaning frame 413 can rotate inside the feeding hopper 2. A power block 414 fixed on the side of the connecting column 412 is inserted into the movable groove 415 on the inner side of the middle part of the cleaning frame 413. A positioning base plate 416 is fixed on the connecting column 412, and an adjustment vertical plate 417 is inserted into the inner side of the positioning base plate 416. The adjustment vertical plate 417 is connected to the positioning base plate 416 through an auxiliary spring 418. A pressure rod 419 fixed inside the feeding hopper 2 is provided on the lower side of the adjustment vertical plate 417. The outer wall of the power block 414 and the inner wall of the movable groove 415 are in contact with each other, and the movable groove 415 is set as a spiral structure.

[0041] In this embodiment, when the raw materials are turned over, the connecting column 412 is controlled by the cylinder 411 to move up and down reciprocally. The up and down reciprocating movement of the connecting column 412 can drive the positioning plate 416 to move synchronously. The reciprocating movement of the positioning plate 416 can turn over the raw materials inside the feeding hopper 2. At the same time, after the connecting column 412 moves downward, the power block 414 on the side can move in the spiral movable groove 415. This allows the cleaning frame 413 with the spiral movable groove 415 to rotate. The rotation of the cleaning frame 413 can also scrape off the raw materials attached to the inner wall of the feeding hopper 2.

[0042] The lower end of the regulating vertical plate 417 is set as an inclined surface on the side near the pressure rod 419, and the upper end of the pressure rod 419 is set as a spherical structure.

[0043] In this embodiment, the regulating vertical plate 417 is mounted on the positioning base plate 416. The reciprocating movement of the positioning base plate 416 can drive the regulating vertical plate 417 to move synchronously. After the regulating vertical plate 417 moves downward, its inclined surface can be squeezed by the spherical end of the pressure rod 419. At this time, the regulating vertical plate 417 moves on the positioning base plate 416. When the positioning base plate 416 moves upward, the regulating vertical plate 417 also moves upward. At this time, the regulating vertical plate 417 is reset under the action of the auxiliary spring 418. The reciprocating movement of the regulating vertical plate 417 can improve the turning effect of the raw materials and further improve the anti-blocking treatment effect of the raw materials.

[0044] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
