Description

Technical Field

[0001] This utility model relates to the field of cable extrusion, specifically to an anti-material accumulation cleaning structure for a multi-layer cable extruder head. Background Technology

[0002] In cable production, multilayer extrusion is a key technology for achieving composite molding of multiple insulation or sheath layers in cables. The extruder head, as the core component of this process, directly affects the quality of the cable product. During long-term use, existing multilayer cable extruder heads are prone to material accumulation on the inner wall of the die head, in the feeding channel, and at the discharge port due to the viscosity of the molten material.

[0003] Long-term accumulation of materials can lead to aging and carbonization, making them not only difficult to clean but also potentially causing wear and tear on the internal structure of the extruder head, thus shortening the equipment's lifespan. Furthermore, the complex design of traditional extruder heads makes disassembly and cleaning cumbersome, requiring significant manpower and time, resulting in reduced production efficiency and increased production costs. Utility Model Content

[0004] The purpose of this invention is to provide an anti-material accumulation cleaning structure for a multi-layer cable extruder head, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A material-preventing and cleaning structure for a multi-layer cable extruder head includes an outer cylinder, a support frame fixedly connected to the lower part of the outer wall of the outer cylinder, a front plate fixedly connected to the front end of the outer cylinder, an installation cylinder one fixedly connected to the end of the front plate away from the outer cylinder, a feed port opened at the upper part of the installation cylinder one, and a feeding pipe fixedly connected to the end of the installation cylinder one away from the front plate.

[0006] As a further embodiment of this utility model: the feeding pipes are arranged in three adjacent groups, and a docking plate is installed between the three adjacent feeding pipes. A fixing pin is fixedly connected to the end of the feeding pipe away from the mounting cylinder.

[0007] As a further embodiment of this utility model: a cavity tube two is fixedly connected to the center of the inner cavity of the outer cylinder, and a cavity tube one and an extrusion tube are fixedly connected to both ends of the cavity tube two, respectively.

[0008] As a further embodiment of this utility model: the inner cavity of the second hollow tube is hollow, and a feeding rod is installed in the inner cavity of the second hollow tube. A connecting rod is fixedly connected to one end of the feeding rod near the first hollow tube.

[0009] As a further improvement of this utility model, the feeding rod is adapted to the inner cavity of the hollow tube II.

[0010] As a further embodiment of this utility model: one end of the extrusion tube is fixedly connected to an opening plate, and one end of the opening plate is installed and fixed to the discharge port of the cavity tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting the feeding rod to be compatible with the inner cavity of the second hollow tube, can scrape the inner wall of the second hollow tube in real time when the feeding rod moves in the inner cavity of the second hollow tube, effectively preventing the molten material from accumulating on the inner wall of the second hollow tube; at the same time, the adjacent arrangement of the three sets of feeding tubes with matching docking plates makes the material conveying process smoother, reduces the residence time of the material in the feeding channel, and further reduces the probability of material accumulation.

[0012] This utility model, through the fixed connection structure between the feeding rod and the connecting rod, allows the feeding rod to reciprocate within the cavity of the second hollow tube when deep cleaning is required. This enables thorough scraping and cleaning of the inner wall of the second hollow tube. The fixed connection between the front plate, the mounting cylinder, and the feeding tube, as well as the setting of the fixing pin, facilitates the disassembly and assembly of each component, making it convenient to thoroughly clean the feeding tube, the connecting plate, and other parts, greatly shortening the cleaning time and improving production efficiency.

[0013] This utility model provides stable support for the entire device through a support frame fixedly connected to the lower part of the outer wall of the outer cylinder, ensuring that the device will not shake during operation. The fixed connections of the two ends of the cavity tube to the cavity tube one and the extrusion tube respectively, as well as the installation and fixation of the perforated plate to the discharge port of the cavity tube two, form a stable material conveying and extrusion channel, ensuring the stability of the extrusion process, improving the forming quality of cable products, and making its structure more optimized and its design more reasonable.

[0018] 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.

[0019] Please see Figures 1-3 In the embodiments of this utility model, please refer to Figure 1 This utility model provides a technical solution: a material-proof cleaning structure for a multi-layer cable extruder head, including an outer cylinder 1. The outer cylinder 1 is made of high-strength alloy steel, which has good high temperature resistance and corrosion resistance, and provides stable protection for the internal structure of the device. A support frame 8 is fixedly connected to the lower part of the outer wall of the outer cylinder 1. The support frame 8 is fixed to the outer cylinder 1 by welding. The bottom of the support frame 8 is provided with an anti-slip pad, which further improves the overall stability of the device and prevents shaking during operation. A front plate 2 is fixedly connected to the front end of the outer cylinder 1. The front plate 2 is detachably connected to the outer cylinder 1 by bolts, which facilitates the maintenance and repair of the internal structure of the device in the future. An installation cylinder 3 is fixedly connected to the end of the front plate 2 away from the outer cylinder 1. The installation cylinder 3 and the front plate 2 are integrally formed, which improves the connection strength. The upper part of the mounting cylinder 3 is provided with a feed inlet 4. The inner wall of the feed inlet 4 is provided with a wear-resistant coating to reduce the wear of the feed inlet 4 during material conveying. The end of the mounting cylinder 3 away from the front plate 2 is fixedly connected to a feeding pipe 5. The feeding pipes 5 are arranged in three adjacent sets with the same inner diameter to ensure that the material conveying volume of each layer is uniform. A connecting plate 6 is installed between three adjacent sets of feeding pipes 5. The connecting plate 6 is made of high-temperature resistant sealing material. It not only connects and fixes the three sets of feeding pipes 5, but also effectively prevents material leakage at the connection of the feeding pipes 5. A fixing pin 7 is fixedly connected to the end of the feeding pipe 5 away from the installation cylinder 1 3. The fixing pin 7 is made of stainless steel and fixes the feeding pipe 5 to the subsequent feeding device by inserting it, ensuring the stability of material feeding. A hollow tube 2 12 is fixedly connected to the center of the inner cavity of the outer cylinder 1. The inner wall of the hollow tube 2 12 is precision polished to reduce the friction between the material and the inner wall and reduce the probability of material accumulation. Hollow tube 1 11 and extrusion tube 9 are fixedly connected to the two ends of the hollow tube 2 12, respectively. The inner cavities of hollow tube 1 11, hollow tube 2 12 and extrusion tube 9 are connected. A complete material conveying channel is formed. One end of the extrusion tube 9 is fixedly connected to an opening plate 15. One end of the opening plate 15 is installed and fixed to the discharge port of the cavity tube 12. The opening specifications on the opening plate 15 are adapted to the extrusion molding requirements of the cable to ensure the molding quality of the cable. The inner cavity of the cavity tube 12 is hollow. A feeding rod 13 is installed in the inner cavity of the cavity tube 12. The feeding rod 13 is adapted to the inner cavity of the cavity tube 12. The outer wall of the feeding rod 13 is tightly fitted to the inner wall of the cavity tube 12. When the feeding rod 13 moves, it can scrape the inner wall of the cavity tube 12. A connecting rod 14 is fixedly connected to the end of the feeding rod 13 near the cavity tube 11. The connecting rod 14 extends to the outside of the outer cylinder 1, which makes it convenient for the operator to control the movement of the feeding rod 13 through the connecting rod 14.

[0020] The working principle of this invention is as follows: In the multi-layer extrusion production process of cables, molten materials of different materials are conveyed to the installation cylinder 3 through three sets of feeding pipes 5, and then enter the cavity tube 11 inside the outer cylinder 1 via the front plate 2, and subsequently flow into the cavity tube 12. During the material conveying process, the operator can pull the connecting rod 14 to drive the feeding rod 13 to move in the cavity of the cavity tube 12. The outer wall of the feeding rod 13 scrapes against the inner wall of the cavity tube 12, and the material accumulates on the inner wall of the cavity tube 12. After the material gathers in the cavity tube 12, it is extruded through the extrusion pipe 9 and the perforated plate 15 to form a multi-layer composite structure of the cable. When the device needs to be cleaned, the fixing pin 7 can be removed first to separate the feeding pipe from the subsequent feeding device. Then, the feeding rod 13 can be driven by the connecting rod 14 to reciprocate in the cavity of the second cavity tube 12 to thoroughly scrape and clean the inner wall of the second cavity tube 12. If the feeding pipe 5 and the connecting plate 6 need to be cleaned, the bolts on the front plate 2 can be removed, and the mounting cylinder 3 and the feeding pipe 5 can be removed as a whole for cleaning. After cleaning, they can be reassembled and put into use.

[0021] Although the present invention 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 invention should be included within the protection scope of the present invention.
