Description

Technical Field

[0001] This application relates to the field of cable production technology, and more specifically, to a production apparatus for low-smoke, halogen-free, high-temperature resistant cables. Background Technology

[0002] High-temperature resistant wires and cables are cables capable of transmitting signals or electrical energy normally at high temperatures. They typically use solid or stranded silver-plated or nickel-plated copper wire, a common type of wire with excellent flame retardancy, aging resistance, and long service life. They are widely used in industries such as communications, automobiles, motors, and construction. In the production process of high-temperature resistant cables, an extrusion molding machine is used to coat the cable surface with plastic to provide protection. In existing technology, when using the extrusion molding machine, plastic granules are first heated to a molten state, and then a certain pushing force is applied to the molten plastic, causing it to be extruded from inside the extrusion molding machine. The extruded plastic then enters the molding die. However, existing extrusion blocks and shells are generally integrated, making it difficult to clean the inside of the shell after use. Therefore, this paper proposes a low-smoke halogen-free high-temperature resistant cable production device that facilitates cleaning. Utility Model Content

[0025] Reference Figure 1-6A low-smoke, halogen-free, high-temperature resistant cable production apparatus 100 includes: a support base 101, a housing 102, an auger 103, a motor 104, an extrusion block 105, and fastening components for loosening and tightening the extrusion block 105 to the housing 102. The housing 102 is located above and fixedly connected to the support base 101. The auger 103 is located inside the housing 102 and rotatably connected to it. The motor 104 is fixedly connected to the housing 102, and its output shaft is fixed to the auger 103. The extrusion block 105 is rotatably connected to the housing 102. A heating wire is provided inside the housing 102 for heating and melting the material. The material used is halogen-free (chlorine, bromine, etc.) and produces low smoke during combustion (such as halogen-free flame-retardant polyolefins and halogen-free elastomers). These materials are typically based on polyolefins and contain a high proportion of halogen-free flame retardants (such as aluminum hydroxide and magnesium hydroxide) to ensure the low-smoke, halogen-free performance of the manufactured cable. Furthermore, high-temperature resistant materials (such as silicone rubber, fluoroplastics, and cross-linked polyolefins) are added, giving the cable high-temperature resistance.

[0026] The housing 102 has a first fixing block 102a at one end, and the extrusion block 105 includes a first connecting plate 105a, which is rotatably connected to the first fixing block 102a. The first fixing block 102a includes a clearance groove for the first connecting block to move. The housing 102 has a feeding port at its upper end for feeding materials.

[0027] The tensioning element is used to loosen and tighten the extrusion block 105 and the housing 102. The tensioning element includes: a second fixing block 106, a second connecting plate 107, a first slider 108, a first spring 109, a limiting block 110, and a push plate 112. The second fixing block 106 is fixedly connected to the housing 102. The second connecting plate 107 is fixedly connected to the extrusion block 105. The first slider 108 is vertically slidably connected to the second connecting plate 107. Specifically, the second connecting plate 107 has a first groove 107a extending along the height direction of the second connecting plate 107, and the first slider 108 moves along the first groove 107a.

[0028] The first spring 109 is fixedly connected at both ends to the second connecting plate 107 and the first slider 108, respectively. The limiting block 110 is fixedly connected to the first slider 108. The push plate 112 is fixedly connected to the first slider 108. The second fixing block includes an insertion groove 106a for the limiting block 110 to be inserted into. The second fixing block also includes a limiting groove 106b for limiting the position of the limiting block 110. The insertion groove 106a and the limiting groove 106b communicate. The push plate 112 is located at one end of the first slider 108, and the limiting block 110 is located at the other end of the first slider 108. The first fixing block 102a is located on one side of the housing 102, and the second fixing block is located on the other side of the housing 102. When it is necessary to clean the extrusion block 105, push the push plate 112. The movement of the push plate 112 causes the first slider 108 to move. The movement of the first slider 108 causes the limiting block 110 to move, so that the limiting block 110 disengages from the limiting groove 106b and moves to the insertion groove 106a. Then rotate the extrusion head to clean the inside of the extrusion head, preventing the extrusion block 105 from becoming clogged due to prolonged disuse.

[0029] Workflow: Production materials are poured into the feeding port, then motor 104 drives auger 103 to rotate, and the material is heated by internal heating wires, thus extruding and melting the material, which is then extruded from extrusion block 105 to shape the plastic and wrap it around the outer arc surface of the cable. When it is necessary to clean extrusion block 105, push plate 112 is pushed, and the movement of push plate 112 drives the first slider 108 to move. The movement of the first slider 108 drives the limiting block 110 to move, causing the limiting block 110 to disengage from the limiting groove 106b and move to the insertion groove 106a. Then, the extrusion head is rotated to clean the inside of the extrusion head, preventing the extrusion block 105 from becoming clogged due to prolonged disuse. The above description is only a few preferred embodiments of this disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-mentioned technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, technical solutions can be formed by replacing the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
