Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1 to Figure 6 As shown, this embodiment provides an extrusion device for processing a cluster tube, comprising:

[0038] An extruder 1, wherein the extruder 1 has a die channel 2;

[0039] A cleaning piece 3, the cleaning piece 3 is arranged on the extruder 1, located on one side of the die head channel 2, the cleaning piece 3 is used to clean the die head channel 2, and the cleaning piece 3 includes:

[0040] A cleaning rack 301, wherein the cleaning rack 301 is arranged on the extruder 1 and located at the die head channel 2;

[0041] A sliding frame 302, wherein the sliding frame 302 is slidably disposed on the cleaning frame 301;

[0042] A plurality of cleaning blocks 303 are arranged circumferentially along the sliding frame 302 . After the sliding frame 302 slides, the cleaning blocks 303 extend into or out of the machine head channel 2 .

[0043] In this embodiment, when using the extruder 1 to wrap the cluster tube on the cable surface, the following problems exist: after shutdown, the plastic cluster tube is likely to remain on the head part of the extruder 1, and when it is restarted, it is easy to get stuck in the head part, making it inconvenient to discharge the material and affecting the quality of subsequent operations. In order to solve the above problems, an extrusion device for processing cluster tubes is designed.

[0044] The traditional method is basically unable to solve the problem of blocking the head channel 2. Usually, after the blockage occurs, the machine is stopped for processing, and the blockage in the head channel 2 is removed manually using tools. The removal process is cumbersome, so a cleaning piece 3 is installed at the head channel 2 of the extruder 1. After the cleaning piece 3 works, the blockage is automatically discharged.

[0045] The cleaning piece 3 is composed of a cleaning frame 301, a sliding frame 302 and a plurality of cleaning blocks 303. The cleaning frame 301 provides a stable support to prevent the cleaning structure from being suspended in the air. The sliding frame 302 is slidably arranged to drive a plurality of cleaning blocks 303 to extend into the head channel 2. After extending into the head channel 2, they are aligned with the inner wall of the head channel 2 and then extended out. In this process, a part of the blockage can be pushed into the extruder 1 for subsequent recycling, and the other part is directly scraped out by the cleaning block 303 to dredge the entire head channel 2 without the intervention of workers. In addition, a plurality of cleaning blocks 303 are arranged circumferentially for more comprehensive cleaning.

[0046] Further, the cleaning member 3 also includes:

[0047] The rotating disk 304 is rotatably disposed on the sliding frame 302 , and a plurality of cleaning blocks 303 are circumferentially disposed along the rotating disk 304 .

[0048] In this embodiment, a rotating disk 304 is added during the extension process of the cleaning block 303, so that the rotating disk 304 can drive several cleaning blocks 303 to more comprehensively clean the inside of the head channel 2, thereby increasing the contact time between the two and improving the cleaning quality.

[0049] Furthermore, the head channel 2 is cylindrical, and the axial direction of the head channel 2, the sliding direction of the sliding frame 302 and the rotational axis of the rotating disk 304 are arranged in a colinear manner.

[0050] In this embodiment, in order to improve the overall operation stability and reduce the occupied area, the head channel 2 is set to be cylindrical, and the axial direction of the head channel 2, the sliding direction of the sliding frame 302 and the rotation axis of the rotating disk 304 are arranged in the same line.

[0051] Further, the cleaning rack 301 includes:

[0052] A column frame 305, wherein the column frame 305 is sleeved on the machine head channel 2, and a gap 306 is formed between the inner wall of the column frame 305 and the machine head channel 2;

[0053] A plurality of fasteners 307 are arranged along the circumference of the column frame 305 and are located in the gap 1 306 . One end of the fastener 307 abuts against the nose channel 2 .

[0054] In this embodiment, in order to facilitate the workers to install the cleaning frame 301 on the head channel 2 in the early stage, a column frame 305 with a similar shape and larger size is used to be sleeved on the head channel 2. After the sleeve is put on, due to the different sizes of the two, the cross-sectional area of ​​the column frame 305 is larger than the cross-sectional area of ​​the head channel 2, so a gap 306 is formed between the two. In order to fix the position of the column frame 305, a plurality of fasteners 307 are installed around the column frame 305. During installation, the worker screws the fastener 307 to make one end of it press against the head channel 2 to complete the installation operation. The sliding frame 302 is slidably set on the column frame 305, the rotating disk 304 rotates on the sliding frame 302, and the cleaning block 303 is still set on the rotating disk 304.

[0055] Furthermore, it also includes a position adjusting member 4, which is used to adjust the position of the cleaning block 303 on the rotating disk 304, and the position adjusting member 4 includes:

[0056] A positioning disk 401, the positioning disk 401 is rotatably disposed on the rotating disk 304, and the positioning disk 401 has an arc-shaped through hole 402;

[0057] The chassis 403 is rotatably connected to the positioning disk 401, the chassis 403 has a gap 2 406, the gap 2 406 has a linear through hole 404, a plurality of cleaning blocks 303 are circumferentially slidably arranged in the gap 2 406 along the chassis 403, the cleaning blocks 303 have a driving part 405, the driving part 405 passes through the linear through hole 404 and the arc through hole 402, and the positioning disk 401 rotates to drive the plurality of cleaning blocks 303 to move closer to or away from each other.

[0058] In this embodiment, in order to discharge the blockage as much as possible instead of pushing it in, so as to prevent damage to the subsequent extrusion process or affect the extrusion quality, an adjusting member 4 is added, and a plurality of cleaning blocks 303 are set on the rotating disk 304 through the adjusting member 4. Before the sliding frame 302 drives it to extend into the head channel 2, the position of the cleaning block 303 on the rotating disk 304 is adjusted by the adjusting member 4 to ensure that the cleaning block 303 does not abut against the inner wall when extending, and then the position of the cleaning blocks 303 is adjusted to abut against the inner wall, and then extended, and at the same time the rotating disk 304 rotates to discharge almost all the blockage.

[0059] The positioning member 4 is similar to a shutter mechanism, and consists of a positioning disk 401 and a chassis 403. Several cleaning blocks 303 are radially slidably arranged in the gap 2 406 along the chassis 403, and the driving part 405 of the cleaning block 303 passes through the linear through hole 404 of the chassis 403 and the arc through hole 402 of the positioning disk 401. Since the chassis 403 is rotatably connected with the positioning disk 401, when the positioning disk 401 is driven to rotate manually or by an electric structure, the chassis 403 will not rotate either, and the arc-shaped channel will abut and drive the driving part 405 to move along the length direction of the linear through hole 404 during this process, that is, several cleaning blocks 303 are moved closer to or farther from each other, so as to achieve the purpose of abutting or canceling the abutment against the inner wall through the rotation of the positioning disk 401.

[0060] Further, the cleaning block 303 includes:

[0061] A V-shaped plate 308, wherein the V-shaped plate 308 is slidably disposed in the second gap 406, and the V-shaped plate 308 has the driving portion 405;

[0062] The scraper 309 is arranged at one end of the V-shaped plate 308 away from the chassis 403. After the V-shaped plate 308 slides, it is used to drive the scraper 309 to abut against the inner wall of the head channel 2, and a scraping area 310 is formed between the scraper 309 and the V-shaped plate 308.

[0063] In this embodiment, in order to improve the cleaning block 303 to better clean the inner wall during movement, a combined structure of a V-shaped plate 308 and a scraper 309 is used. The scraper 309 is set at the end of the V-shaped plate 308 away from the chassis 403, which can scrape more blockages and achieve a better scraping effect. At the same time, the V-shaped plate 308 and the scraper 309 form a scraping area 310, which is convenient for limiting the blockage therein. After scraping, it is also convenient for workers to collect it. The V-shaped plate 308 also separates various areas of the inner wall for quick cleaning.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
