Description
Technical Field
[0001] This utility model relates to the field of extruder technology, and in particular to an extruder barrel structure that is easy to clean. Background Technology
[0002] Extruders are core equipment for processing polymer materials such as plastics and rubber. Through the rotation of the screw and the cooperation of the barrel, solid materials are heated, melted, and plasticized under pressure before being continuously extruded into specific shapes. The core component, the barrel, is a cylindrical metal cylinder. The core function of the barrel is to work in conjunction with the screw to process the materials. It receives and transports the solid materials entering from the feed inlet. By cooperating with an external temperature control system, heat is provided to the materials to promote their gradual melting. At the same time, under the push of the screw, the barrel assists in compacting the materials, reducing voids, and accelerating the plasticizing process.
[0003] In the field of plastics processing, the extruder barrel is the core component for material plasticization and conveying. The cleanliness of its inner wall directly affects product quality and production efficiency. However, during long-term operation, due to the viscosity of the plastic melt and the inevitable temperature fluctuations and material residues during processing, some plastic can easily form an adhesive layer on the inner wall of the barrel. If these adhesive plastics are not removed in time, they will gradually solidify and accumulate, which not only affects the plasticization uniformity of subsequent materials, but may also produce impurities due to high-temperature decomposition, leading to defects in the extruded products, or even barrel blockage, forcing production to stop. Currently, regarding the cleaning needs of the inner wall of the extruder barrel, on the one hand, traditional barrels mostly adopt an integral or fixed structure design, which is closely connected to the main body of the extruder. The disassembly process is complicated and requires a lot of manpower and time, which seriously affects the continuity of production. On the other hand, if a non-disassembly cleaning method is adopted, operators often need to use rigid tools to directly scrape off the residue on the inner wall. This can easily cause the smooth surface of the inner wall of the barrel to be scratched, forming scratches or dents. Once the inner wall is damaged, it will increase the probability of subsequent material adhesion, significantly shorten the service life of the barrel, and increase equipment maintenance costs and production risks.
[0004] Therefore, it is necessary to invent an extruder barrel structure that is easy to clean in order to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide an extruder barrel structure that is easy to clean, in order to solve the problem mentioned in the background art. Currently, for the cleaning needs of the inner wall of the barrel, on the one hand, traditional barrels mostly adopt an integral or fixed structure design, which is closely connected to the main body of the extruder. The disassembly process is complicated and requires a lot of manpower and time, which seriously affects the continuity of production.

[0016] Please see the appendix Figure 1 - Appendix Figure 4 An easy-to-clean extruder barrel structure includes an extruder body 1, a base plate 11 fixedly connected to the bottom end of the extruder body 1, a feed pipe 12 provided on one side of the extruder body 1, and a connecting pipe 13 fixedly connected to the top end of the feed pipe 12. The extruder body 1 is an existing mature technology, which can effectively drive the internal plastic raw material to move and be extruded from the end of the feed pipe 12. A barrel body 2 is provided at the top end of the connecting pipe 13, and a guide pipe 25 is provided between the barrel body 2 and the connecting pipe 13. A connecting flange 24 is fixedly connected to the bottom end of the barrel body 2 and the top end of the guide pipe 25. A connecting flange 24 is fixedly connected to the top end of the connecting pipe 13 and the bottom end of the guide pipe 25. A connecting arc plate 3 is provided on the inner side of the barrel body 2, and a protective layer 31 is provided on the inner side of the connecting arc plate 3.
[0017] Specifically, by setting up a barrel body 2, a guide pipe 25 is set at the bottom end of the barrel body 2, and a connecting pipe 13 is set at the bottom end of the guide pipe 25. The barrel body 2 and the guide pipe 25 are fixedly connected by a connecting flange 24. At the same time, the connecting pipe 13 and the guide pipe 25 are also fixedly connected by a connecting flange 24. Thus, when it is necessary to clean the barrel body 2 and the guide pipe 25, they can be quickly disassembled for subsequent cleaning work. By setting a connecting arc plate 3 on the inner side of the barrel body 2, and a protective layer 31 on the inner side of the connecting arc plate 3, the plastic can remain on the protective layer 31, which is convenient for subsequent replacement or cleaning work and avoids damage to the inner wall of the barrel body 2. The protective layer 31 is made of Teflon, which can effectively reduce heating loss and avoid the additional energy consumption caused by the carbonization of residual materials.
[0018] Please see the appendix Figure 2 and Figure 3 The barrel body 2 is composed of a first arc plate 21 and a second arc plate 22. The upper and lower ends of the first arc plate 21 and the second arc plate 22 are fixedly connected to side fixing blocks 212 on opposite sides.

[0019] Specifically, by setting the first arc-shaped plate 21 and the second arc-shaped plate 22, they can be quickly assembled and used. Side fixing blocks 212 are fixedly connected to the sides of both the first arc-shaped plate 21 and the second arc-shaped plate 22, which can be fixed with bolts and nuts, thereby effectively splicing and fixing the first arc-shaped plate 21 and the second arc-shaped plate 22. By setting the second positioning block 216, the side of the second arc-shaped plate 22 is provided with holes corresponding to the second positioning block 216, thereby enabling the first arc-shaped plate 21 and the second arc-shaped plate 22 to be quickly spliced.
[0020] Please see the appendix Figure 3 The inner side of the first arc plate 21 is provided with a cross-shaped slot 211, and multiple heating elements 213 are symmetrically arranged on the inner side of the first arc plate 21.
[0021] Specifically, by setting a heating element 213, a connector electrically connected to the heating element 213 is provided on the outer side of the first arc plate 21, which facilitates connection with an external power source. When it is necessary to heat the heating element 213, the connector can be connected to an external power source to heat the heating element 213.

The cross-shaped locking block 32 is slidably connected to the inner side of the cross-shaped locking groove 211. An installation hole 33 is opened on the inner side of the middle part of the cross-shaped locking block 32. A fastening bolt 23 is threadedly connected to the inner side of the installation hole 33.
[0025] Specifically, a cross-shaped locking block 32 is fixedly connected to one side of the connecting arc plate 3. The cross-shaped locking block 32 is slidably connected to the inside of the cross-shaped locking groove 211, thereby effectively limiting the sliding of the cross-shaped locking block 32 to the inside of the cross-shaped locking groove 211. An installation hole 33 is provided on the inside of the cross-shaped locking block 32. The first arc plate 21 is provided with a hole corresponding to the installation hole 33 at the corresponding position, which can effectively thread the fastening bolt 23 to the inside of the installation hole 33, thereby effectively fixing the cross-shaped locking block 32 to the inside of the cross-shaped locking groove 211, thereby effectively fixing the connecting arc plate 3 to the inside of the first arc plate 21.
[0026] The working principle of this utility model is as follows: In specific use, a material cylinder body 2 is set, and a guide pipe 25 is set at the bottom end of the material cylinder body 2. A connecting pipe 13 is set at the bottom end of the guide pipe 25. The material cylinder body 2 and the guide pipe 25 are fixedly connected by a connecting flange 24.
