[0003] In actual operation, the raw materials for Teflon plastic pipes are directly fed into the extruder through the hopper. The granular raw materials are heated and melted before being extruded from the outlet. During this process, the granular raw materials are prone to moisture absorption and clumping, which may cause the extruder to feed unevenly, affecting production efficiency. It may even cause blockages inside the extruder, leading to equipment failure, increased maintenance costs and downtime, which has a negative impact on the production of Teflon plastic pipes and is quite inconvenient.

Detailed Implementation

[0042] 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.

[0043] Example 1

[0044] This utility model provides, for example Figure 1-4 The high-temperature extruder shown includes a body 1, a motor 3, a feeding mechanism 4, and a filtering mechanism 5. A feeding hopper 2 is fixedly connected to the top of the body 1. The motor 3 is fixedly installed at the top of the feeding hopper 2 and is electrically connected to an external power supply via an external switch. The motor 3 drives the feeding mechanism 4 to rotate inside the feeding hopper 2. The filtering mechanism 5 is located inside the feeding hopper 2 and is used to work with the feeding mechanism 4 to filter, extrude, and crush materials. The filter plate 51 can block agglomerated materials from above. Driven by the motor 3, the stirring blades 43 and extrusion blocks 44 in the feeding mechanism 4 and the extrusion rod 52 interweave to form an extrusion and shearing action. This allows the conveying auger 42 to feed materials at a uniform speed while crushing agglomerated materials. This effectively prevents agglomerated materials from entering the extruder and causing blockages, ensuring the stability and continuity of feeding, avoiding equipment failures and production interruptions caused by material blockages, improving the efficiency and quality of Teflon plastic pipe production, and reducing equipment maintenance costs and worker labor intensity.

[0045] Specifically, the feeding mechanism 4 includes a rotating rod 41, a conveying auger 42, a stirring blade 43, and extrusion blocks 44. The output end of the motor 3 is connected to the rotating rod 41. One end of the conveying auger 42 is fixedly connected to the bottom end of the rotating rod 41. The stirring blade 43 is fixedly connected to the outer wall of the rotating rod 41 at equal intervals. Grooves are provided at equal intervals on the outer wall of the stirring blade 43. The extrusion blocks 44 are fixedly connected to the outer wall of the stirring blade 43 at equal intervals. The cross-section of the extrusion blocks 44 is triangular. The motor 3 can drive the rotating rod 41 to rotate, so that the conveying auger 42 can convey materials at a uniform speed while driving multiple extrusion blocks 44 on the stirring blade 43 to rotate. During the rotation, the triangular extrusion blocks 44 can more effectively squeeze and shear the agglomerated materials, and are less prone to deformation or displacement, ensuring a stable processing effect on the agglomerated materials. Secondly, the sharp corner of the triangle can better cut into the interior of the agglomerated materials and crush the agglomerated materials more efficiently. Compared with other shapes, it can play a better role in squeezing and crushing, thereby more effectively preventing the agglomerated materials from affecting the feeding process and equipment operation.

[0046] The specific filtration mechanism 5 includes a filter plate 51 and an extrusion rod 52. Installation grooves are provided on both sides of the feed hopper 2. The filter plate 51 is slidably inserted into the inner cavity of the installation groove. A through groove for the rotation of the rotating rod 41 is provided on the opposite side of the filter plate 51. The filter plate 51 can prevent agglomerated materials from directly entering the interior of the machine body 1. The extrusion rods 52 are fixedly connected at equal intervals to the top of the filter plate 51. The extrusion rods 52 cooperate with the extrusion blocks 44. When the stirring blade 43 rotates, the extrusion rods 52 can pass through the grooves opened on the stirring blade 43. Thus, when the stirring blade 43 rotates, the interlacing of multiple extrusion rods 52 and multiple extrusion blocks 44 forms a shearing action, causing the agglomerated materials to be broken into suitable sizes, facilitating subsequent feeding operations.

[0047] Example 2

[0048] Based on Example 1, such as Figure 5-6 As shown, the filter mechanism 5 also includes a positioning rod 53, a pull rod 54, a compression spring 55, and a limiting component 56. A positioning groove is provided at the top of the inner wall of the mounting groove, and a positioning hole is provided at the top of the filter plate 51. One end of the positioning rod 53 is slidably inserted into the inner cavity of the positioning groove, and the other end of the positioning rod 53 is slidably inserted into the inner cavity of the positioning hole. Pull grooves communicating with the positioning groove are provided on both sides of the feed hopper 2. The pull rod 54 passes through the pull groove and is fixedly connected to the positioning rod 53. The compression spring 55 is set inside the positioning groove. One end of the compression spring 55 is fixedly connected to the positioning rod 53, and the other end of the compression spring 55 is fixedly connected to the top of the inner wall of the positioning groove. The compression spring 55 is always in a compressed state, thereby providing a stable elastic force to the positioning rod 53, so that the positioning rod 53 can be stably inserted into the positioning hole, thereby stably fixing the filter plate 51 inside the feed hopper 2. The limiting component 56 is set on the pull rod 54 to limit the displacement of the positioning rod 53.

[0049] Specifically, the limiting component 56 includes a slider 561, a locking rod 562, a locking plate 563, a magnet 564, and an iron sheet 565. The top of the pull rod 54 has a groove, and the slider 561 is slidably inserted into the inner cavity of the groove. The locking rod 562 is fixedly connected to the top of the slider 561. The locking rod 562 has an L-shaped cross-section, and its top has an inclined surface. The locking plate 563 is fixedly connected to both sides of the feed hopper 2. The locking plate 563 has locking holes, and the locking rod 562 is slidably inserted into the inner cavity of the locking holes. After the locking rod 562 passes through the locking holes through a certain deformation, it can be stopped by its own weight and the elastic force of the compression spring 55. The positioning rod 53 is kept out of the positioning hole. Magnets 564 are fixedly connected to both sides of the slider 561. Iron pieces 565 are embedded in both sides of the inner wall of the slide groove. Magnets 564 and iron pieces 565 cooperate with each other. The magnets 564 on both sides of the slider 561 attract iron pieces 565 at different positions. The position of the locking rod 562 can be adjusted, thereby limiting the pull rod 54 that drives the positioning rod 53 to move. This can effectively prevent the installation failure due to machine vibration during use. At the same time, it can also keep the position unchanged after the pull rod 54 pulls the positioning rod 53 out of the positioning hole, which facilitates subsequent cleaning and reinstallation operations and makes it easy to use.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
