Description

Technical Field

[0001] The utility model relates to the technical field of wire extruders, in particular to a power line fixing device for an electric heating rod of a wire extruder head. Background Art

[0002] A cable extruder is a piece of machinery specifically designed for producing cables. During operation, a heating rod is typically installed in the die head to heat the extruder. This process is crucial for ensuring a smooth cable extrusion process, as proper heating ensures the plasticity and fluidity of the cable material, thereby guaranteeing cable quality and performance. For example, Chinese Patent Publication No. "CN207834018U" discloses a Teflon cable extruder die head.

[0003] However, current heating rod power cords are typically exposed outside the die head, making them susceptible to high temperatures and potentially damaging their surface. Furthermore, without a secure, protective barrier, the power cord is susceptible to accidental contact or pulling, potentially causing damage. These issues not only impact the stability and reliability of cable extruders but also increase maintenance costs and safety risks. Therefore, it is necessary to design a power cord securing device for heating rods in cable extruder die heads to address these issues. Utility Model Content

[0004] The purpose of the utility model is to solve the disadvantage in the prior art that the power cord of the heating rod is usually exposed outside the head, which poses a hidden danger in use, and to propose a power cord fixing device for the electric heating rod of the wire extrusion head.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A power cord fixing device for an electric heating rod of an electric wire extruder head is designed, comprising a fixing block fixed to one side of the extruder head, a wire fixing block installed at the upper and lower ends of the fixing block, and a wire end pressing structure detachably connected to the outer side of the wire fixing block;

[0007] A surface wire pressing structure is detachably connected to the front end surfaces of the fixing block and the wire fixing block, and a channel for laying the power line is formed between the end wire pressing structure and the surface wire pressing structure.

[0008] Furthermore, the end wire pressing structure includes a wire pressing block, on the end face of the wire pressing block facing away from the wire fixing block is fixedly mounted a reinforcing piece 1, wherein the reinforcing piece 1 is provided with a locking piece 1 connected to the wire fixing block.

[0009] Furthermore, the surface pressing structure includes a protective cover, and a second reinforcing piece is fixedly installed on the end surface of the protective cover facing away from the fixed block, wherein the second reinforcing piece is fixed to the fixed block via a second locking piece.

[0010] Furthermore, the wire pressing block and the first reinforcing sheet, as well as the protective cover and the second reinforcing sheet are detachably connected via connectors.

[0011] Furthermore, the wire pressing block and the protective cover are both configured as alloy stone parts, and the first reinforcement sheet and the second reinforcement sheet are both configured as stainless steel parts.

[0012] Furthermore, the channel includes a wire passing groove formed on the wire fixing block and an avoidance groove formed on the inner side of the protective cover.

[0013] Furthermore, the wire passing groove is arranged obliquely on the end surface of the wire fixing block.

[0014] The utility model proposes a power cord fixing device for the electric heating rod of the wire extrusion machine head, and the beneficial effect is that the utility model design adopts an end-pressing wire structure and a surface-pressing wire structure. The main function of these two structures is to compress and fix the power cord. The advantage of this design is that it adopts two vertical surface fixing methods, so that the power cord can be fixed more effectively. In addition, the power cord is hidden in the channel inside the end-pressing wire structure and the surface-pressing wire structure. This hidden design reduces the contact of the power cord with the outside world and is more beautiful as a whole. In general, this design can effectively fix the power cord of the electric heating rod at the machine head, improve its stability and protection, and thus reduce the probability of damage.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1An embodiment of the present utility model discloses a power cord fixing device for an electric heating rod of an electric wire extruder head. The fixing device is used to fix the power cord of the electric heating rod at the head of the extruder to improve its stability and protection and reduce the probability of damage. Specifically, the fixing device includes a fixing block 2 fixed to one side of the extruder head 1. The fixing block 2 described in this embodiment is preferably set as an iron block, which can be fixed to the outside of the extruder head 1 by welding. A wire fixing block 3 is installed at the upper and lower ends of the fixing block 2. The outer side of the wire fixing block 3 is detachably connected to an end pressure structure 4;

[0019] A surface wire pressing structure 5 is detachably connected to the front end surfaces of the fixing block 2 and the wire fixing block 3 , and a channel for laying the power line 6 is formed between the end wire pressing structure 4 and the surface wire pressing structure 5 .

[0020] In some embodiments, the end wire pressing structure 4 in the present invention includes a wire pressing block 41, and a reinforcing piece 42 is fixedly installed on the end face of the wire pressing block 41 facing away from the wire fixing block 3, wherein the reinforcing piece 42 is provided with a locking piece 43 connected to the wire fixing block 3. Preferably, the locking piece 43 described in this embodiment is configured as a bolt, which is sequentially passed through the reinforcing piece 42 and the wire pressing block 41 and is threadedly connected to the wire fixing block 3.

[0021] In addition, based on the above embodiments, the surface pressing structure 5 in this embodiment includes a protective cover 51, and a reinforcing plate 2 52 is fixedly installed on the end face of the protective cover 51 facing away from the fixed block 2, wherein the reinforcing plate 2 52 is fixed to the fixed block 2 through a locking member 2 53. Similarly, the locking member 2 53 in this embodiment is also set as a bolt. As a preferred embodiment, two locking members 2 53 are designed in this embodiment to improve the installation stability of the protective cover 51. Of course, the bolts pass through the reinforcing plate 2 52 and the protective cover 51 in turn, and then are threadedly connected to the fixed block 2.

[0022] It should be noted that the wire pressing block 41 and the reinforcement piece 1 42, as well as the protective cover 51 and the reinforcement piece 2 52 in this embodiment are detachably connected via a connecting piece 7. Specifically, the connecting piece 7 in this embodiment is a flat-head bolt. By using flat-head bolts to install and fix the reinforcement piece 1 42 and the reinforcement piece 2 52, convenient assembly and disassembly can be achieved. In addition, the design of the reinforcement piece 1 42 and the reinforcement piece 2 52 is used to improve the connection strength of the wire pressing block 41 and the protective cover 51.

[0023] In addition, the wire pressing block 41 and the protective cover 51 in the embodiment of the present invention are both configured as alloy stone parts, and the alloy stone parts are processed from high-temperature resistant synthetic stone materials. Alloy stone is a composite material mixed with metal particles and resin. Common alloy stones on the market include marble quartz stone, granite quartz stone, etc., and the reinforcing plate 1 42 and the reinforcing plate 2 52 are both configured as stainless steel parts.

[0024] In some embodiments, the channel in the present invention includes a wire passing groove 8 formed on the wire fixing block 3 and an avoidance groove formed on the inner side of the protective cover 51. Specifically, the wire passing groove 8 in this embodiment is inclined on the end face of the wire fixing block 3. The inclined wire passing groove 8 can improve the tensile strength of the power cord 6. In this embodiment, every two wire passing grooves 8 form a group to adapt to the positive and negative wires in the power cord 6. The avoidance groove on the protective cover 51 is used to hide the power cord. The bottom end of the avoidance groove passes through the lower side of the protective cover 51 to facilitate the power cord 6 to pass through. Secondly, the power cord 6 is tightened by the side of the protective cover 51, which further improves the fixing stability of the power cord 6. It should be noted that the depth of the wire passing groove 8 and the avoidance groove described in the present invention are both less than the thickness of the power cord 6, so as to ensure that part of the power cord 6 protrudes to facilitate the tightening operation.

[0025] In summary, the design of the present invention adopts an end-pressing structure 4 and a surface-pressing structure 5. The main function of these two structures is to compress and fix the power cord 6. The advantage of this design is that it adopts two vertical surface fixing methods, so that the power cord 6 can be fixed more effectively. In addition, the power cord 6 is hidden in the channel inside the end-pressing structure 4 and the surface-pressing structure 5. This hidden design reduces the contact of the power cord 6 with the outside world and is more beautiful as a whole. In general, this design can effectively fix the electric heating rod power cord 6 at the head of the machine, improve its stability and protection, and thus reduce the probability of damage.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
