Abstract
Description
Technical Field
[0001] This utility model relates to auxiliary tools for extruders, specifically to a high-efficiency auxiliary cleaning device for the extruder head. Background Technology
[0002] In the extrusion production process of wires and cables, after the plastic is heated and plasticized by the screw at high temperature inside the extruder head, it will wrap around the surface of the cable core through the small holes evenly distributed on the perforated plate of the extruder head.
[0003] like Figure 4 As shown, the perforated plate 3 is a disc-shaped structure with holes 31 extending through both ends. When the extruder stops and the die head needs to be replaced, plastic residue remains inside the holes 31 of the perforated plate 3. Because the temperature drops rapidly after the perforated plate 3 is removed, cleaning the remaining plastic residue inside the holes 31 is extremely difficult. Currently, the common cleaning method is to use needle-nose pliers to pull out the plastic residue piece by piece; however, this method is ineffective for plastic residue that is not exposed within the holes 31. This traditional cleaning method is not only time-consuming and labor-intensive, but also seriously affects production efficiency and increases the workload of operators.
[0004] In view of this, it is necessary to design a cleaning device to solve the above-mentioned technical problems. Utility Model Content

[0013] Furthermore, the outer end of the straight column is chamfered or configured as a pointed structure.
[0014] Furthermore, the pointed structure has a cylindrical head at the outer end of the straight column, the diameter of which is smaller than the diameter of the straight column.
[0015] Furthermore, the pressing part includes a first disk and a second disk that are stacked and fixed together, wherein the diameter of the second disk is smaller than the diameter of the first disk and the first disk and the second disk are concentrically arranged.
[0016] Furthermore, the first disc is a plastic disc.
[0017] Furthermore, the second disk is a metal disk used as a counterweight.
[0018] Furthermore, the handle is a T-shaped rod, the vertical part of which is connected to the center of the second disc.

[0029] Example 1: The specific structure of this utility model is as follows:
[0030] Please refer to the appendix. Figure 1-6 This utility model discloses a high-efficiency auxiliary cleaning device for the extruder head, comprising:
[0031] The cylinder 4 has a through cavity that extends through both ends, and its wall surface has a plurality of side holes 41 that serve as viewing windows. There are three side holes 41, which are arranged in a ring array on the side circumferential surface of the cylinder 4. The function of the side holes 41 is to check whether the cleaning mold 2 is pressed into place.
[0032] A cleaning mold 2 has an outer rafter profile adapted to the cavity, its first surface is a plane, and its second surface is distributed with multiple straight columns 22;
[0033] The pressure tool 1 has a counterweight pressure part and a handle 11 connected to the pressure part. The pressure part can enter the through cavity and apply pressure to the first surface of the cleaning mold 2 by external force.
[0034] The cylinder 4 has a cylindrical structure.
[0035] The inner wall of the cylinder 4 is provided with a circumferential retaining ring 42. The retaining ring 42 is located near the side hole 41. After the straight column 22 on the cleaning mold 2 and the hole 31 on the perforated plate 3 are manually aligned from the outside, they are placed into the through cavity of the cylinder 4. The retaining ring 42 blocks the perforated plate 3, and a residue collection space is formed below the retaining ring 42.
[0036] The cleaning mold 2 is an integral structure, comprising a disc body 21, with multiple straight pillars 22 vertically distributed on the second surface of the disc body 21. The outer ends of the straight pillars 22 are chamfered or set as pointed structures, which makes it easier for the straight pillars 22 to enter the holes 31 of the perforated plate 3.
[0037] The pointed structure is provided with a cylindrical head 23 at the outer end of the straight column 22, the diameter of which is smaller than the diameter of the straight column 22.
[0038] The pressing part includes a first disk 13 and a second disk 12 that are stacked and fixed together. The diameter of the second disk 12 is smaller than the diameter of the first disk 13, and the first disk 13 and the second disk 12 are concentrically arranged.
[0039] The first disc 13 is a plastic disc.
[0040] The second disc 12 is a metal disc used as a counterweight, and the metal disc is a counterweight iron block.
[0041] The handle 11 is a T-shaped rod, and the vertical part of the T-shaped rod is connected to the center of the second disk 12.
[0042] Example 2:
[0043] The following describes the working process of this utility model's high-efficiency auxiliary cleaning device for cleaning plastic residue:
[0044] In actual use, first take out the perforated plate 3 from the extruder head, take a cleaning mold 2, make the straight column 22 on the cleaning mold 2 correspond to the hole 31 on the perforated plate 3, and finally put the corresponding perforated plate 3 and cleaning mold 2 into the cylinder 4 together, wherein the perforated plate 3 is at the bottom and is blocked by the retaining ring 42.
[0045] Finally, the operator holds the handle 11 of the press 1, puts the pressing part of the press 1 into the cavity of the cylinder 4, and repeatedly hammers the first side of the cleaning mold 2 to apply pressure, and checks through the side hole 41 whether the straight column 22 has completely entered the hole.
[0046] Under pressure, the straight column 22 on the cleaning mold 2 pushes out the plastic residue in the hole 31, thus completing the cleaning work.
[0047] In summary, the high-efficiency auxiliary cleaning device for the extruder head provided by this utility model, through the coordinated design of the cylinder, cleaning mold, and pressure fixture, can quickly and easily clean plastic residue from the perforated plate of the extruder head in one go. During the cleaning process, simply place the cleaning mold on the perforated plate, then place the cylinder over the cleaning mold, and apply pressure through the pressure fixture. This causes the straight column on the cleaning mold to push the plastic residue out of the small holes in the perforated plate, making operation simple and convenient. This device not only saves time and labor, reducing the workload of the main operator, but also significantly improves production efficiency. Furthermore, it has advantages such as simple structure, high reliability, good applicability, and cost-effectiveness, making it highly valuable for widespread application.
