[0024] Example 1

[0025] A continuous pipe extruder with a feeding blockage prevention function includes an extruder body 1 and a feeding mechanism 2; the feeding mechanism 2 is connected to the feed port of the body; the feeding mechanism 2 includes: a feeding hopper 20, a crushing assembly 21 and a stirring member 22; the feeding hopper 20 is connected to the feed port of the extruder body 1, the crushing assembly 21 and the stirring member 22 are both arranged in the feeding hopper 20, and the stirring member 22 is arranged below the crushing assembly 21. The crushing assembly 21 is used to crush the material entering the feeding hopper 20, and the stirring member 22 is used to stir the crushed material.

[0026] The internal structure of the extruder body 1 is a common extruder structure in the prior art and is not improved in this application and will not be described in detail here. The feed hopper 20 is designed to be funnel-shaped, larger at the top and smaller at the bottom, to facilitate smooth material introduction. The material is selected from wear-resistant and corrosion-resistant stainless steel or alloy materials to ensure stability and durability under long-term use. The feed hopper 20 is tightly connected to the feed port of the extruder body 1 by flange connection or welding to ensure sealing and stability during material transmission.

[0027] For reference, the crushing assembly 21 includes a filter element 210, a driving element 211 and a crushing element 212. The filter element 210 is connected to the inner wall of the feeding hopper 20, and the driving element 211 is arranged below the filter element 210. The output end of the driving element 211 passes through the filter element 210 and is connected to the crushing element 212.

[0028] Filter element 210 is designed as a mesh or sieve plate structure with an appropriate aperture. The aperture size is set according to the maximum size of the material to be crushed, ensuring that large pieces of material larger than the aperture are retained on filter element 210, while materials smaller than or equal to the aperture can pass directly through. A drive element 211 (such as an electric motor or hydraulic motor) is installed below filter element 210. Its output end passes through filter element 210 and is connected to crushing element 212. Crushing element 212 is located above filter element 210 and directly acts on large pieces of material retained on filter element 210. Crushing element 212 can be a rotating cutter disc. Driven by drive element 211, crushing element 212 crushes large pieces of material on filter element 210 until the material size is reduced to a size that can pass through the aperture of filter element 210.

[0029] In this embodiment, raw materials (such as plastic particles) are fed into the feed port at the top of the feed hopper 20. Large pieces of material larger than the aperture are retained on the filter element 210, while materials smaller than or equal to the aperture pass directly through the filter element 210 and enter the next part of the feed hopper 20 or directly enter the stirring area. The large pieces of material retained on the filter element 210 are driven by the driving element 211 and acted upon by the crushing element 212 (such as a rotating cutter disc). The crushing element 212 crushes the large pieces of material by high-speed rotation or a specific motion trajectory until the size of the material is reduced to a size that can pass through the aperture of the filter element 210. The crushed material falls into the stirring area, and the stirring element 22 (such as a propeller, stirring rod, etc.) starts to work to stir the material to prevent the material from agglomerating or clogging when entering the feed port of the extruder body 1. The material entering the extruder undergoes heating, melting, extrusion and other processes inside the extruder to finally be made into a pipe product.

[0030] In this embodiment, the large bulk materials are pre-processed by the crushing component 21 to ensure that only small materials that meet the requirements enter the extruder body 1. At the same time, the crushed materials are continuously stirred by the stirring element 22, which effectively prevents blockage problems caused by excessive size or agglomeration of materials, thereby improving production efficiency and stability.

[0031] Example 2

[0032] like Figure 3 As shown, the filter element 210 includes a first inclined support portion 213, a horizontal filter portion 214, and a second inclined support portion 215. One side of the first inclined support portion 213 is connected to the inner wall of one side of the feeding hopper 20, and the other side of the first inclined support portion 213 is connected to one side of the horizontal filter portion 214. One side of the second inclined support portion 215 is connected to the other side of the horizontal filter portion 214, and the other side of the second inclined support portion 215 is connected to the other inner wall of the feeding hopper 20. The side of the first inclined support portion 213 connected to the feeding hopper 20 is higher than the side connected to the horizontal filter portion 214, and the side of the second inclined support portion 215 connected to the feeding hopper 20 is higher than the side connected to the horizontal filter portion 214. The driving member 211 is disposed below the horizontal filter portion 214, and the output end of the driving member 211 passes through the horizontal filter portion 214 and is connected to the crushing member 212. The crushing diameter of the crushing member 212 is the same as the length of the horizontal filter portion 214.

[0033] Among them, the first inclined support portion 213 starts from the inner wall of one side of the feeding hopper 20 and extends downward and inward at an angle. Its main function is to support and guide the material to slide toward the horizontal filter portion 214. The first inclined support portion 213 does not have filter holes and only serves as a support and guiding structure. The horizontal filter portion 214 connects the first inclined support portion 213 and the second inclined support portion 215 to form a horizontal filtering platform. The horizontal filter portion 214 is densely covered with filter holes of appropriate apertures to intercept large pieces of material and allow material smaller than the aperture to pass through. Appropriate space or holes are reserved on the horizontal filter portion 214 so that the output end of the drive member 211 can pass through these reserved positions to connect with the crushing member 212. The second inclined support portion 215 starts from the inner wall of the other side of the feeding hopper 20 and extends downward and inward at an angle to the horizontal filter portion 214. Similarly, the second inclined support portion 215 does not have a filtering function and only serves to support and guide.

[0034] In this embodiment, raw materials first enter through the top of the feed hopper 20 and, guided by the first inclined support portion 213 and the second inclined support portion 215, slide along its inclined surface to the horizontal filter portion 214. Large impurities are trapped in the horizontal filter portion 214, while fine plastic particles pass through the filter holes and fall into the stirring area below or directly into the extruder body 1. At this point, the drive element 211 is activated, driving the crushing element 212 to rotate and crush the large impurities trapped in the horizontal filter portion 214. The crushed material is reduced in size to a level that can pass through the filter holes and then enters the subsequent production process along with the fine plastic particles. This not only effectively prevents clogging of the extruder, but also improves the utilization rate of the raw materials and the quality of the pipe.

[0035] Example 3

[0036] like Figure 4 As shown, the driving member 211 is a double-headed motor. The first output end of the driving member 211 passes through the horizontal filtering part 214 and is connected to the crushing member 212. The second output end of the driving member 211 is connected to the stirring member 22. The stirring member 22 includes a stirring shaft 221 and a stirring blade 222. The stirring shaft 221 is connected to the second output end of the driving member 211, and the stirring blade 222 is connected to the stirring shaft 221. There are multiple stirring blades 222, and the multiple stirring blades 222 are distributed at intervals on the stirring shaft 221. The multiple stirring blades 222 are arranged on both sides of the stirring shaft 221, and the stirring blades 222 on both sides are staggered.

[0037] Among them, in order to further improve the efficiency and uniformity of material processing, a double-headed motor is used as the driving member 211, which drives the crushing member 212 and the stirring member 22 at the same time. This design enables the filtering, crushing and stirring processes to be carried out more coordinated, thereby optimizing the working performance of the entire feeding mechanism 2. The double-headed motor is fixed at an appropriate position below the horizontal filter section 214 to ensure that the two output ends can be connected to the crushing member 212 and the stirring member 22 respectively. The selection of the motor needs to be carried out according to actual needs to provide sufficient power support. The first output end of the double-headed motor passes through the horizontal filter section 214 through a sealing device and is connected to the crushing member 212 (such as a rotating cutter disc). The crushing member 212 rotates under the drive of the motor to crush the large pieces of material trapped on the horizontal filter section 214. The stirring shaft 221 is directly connected to the second output end of the double-headed motor. A plurality of stirring blades 222 are distributed at intervals on the stirring shaft 221 and are arranged on both sides of the stirring shaft 221. The stirring blades 222 on both sides are staggered to increase the stirring effect and coverage. The shape and number of the mixing blades 222 can be adjusted based on the material characteristics and processing requirements. When the dual-head motor is activated, its first output end rotates the crushing element 212, breaking up bulky materials. Simultaneously, the second output end rotates the stirring shaft 221, causing the mixing blades 222 to rotate accordingly. The staggered design of the mixing blades 222 ensures that the materials are thoroughly mixed and dispersed during the mixing process. The dual-head motor simultaneously drives the crushing element 212 and the mixing element 22, achieving simultaneous crushing and mixing.

[0038] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
