Description

Technical fields:

[0001] This utility model relates to the field of wire braiding technology, and specifically to a device for preventing vibration and bending of braided wire. Background technology:

[0002] Cables are essential components for communication, transmission, and power supply, and are ubiquitous in daily life. The typical layered structure of cables generally includes a core wire, an insulation layer, a shielding layer, and an outer sheath. The outer sheath, being the outermost layer, primarily protects the insulation layer from mechanical damage, moisture intrusion, and chemical corrosion, and is usually made of materials such as PVC and polyethylene. With advancements in cable manufacturing technology, it has been discovered that braiding techniques can replace the conventional outer sheath, offering superior wear resistance, corrosion resistance, and high toughness, making it suitable for numerous fields such as home appliances, automobiles, power generation, and medical devices.

[0003] Generally, the production of braided wire is more difficult than that of ordinary PVC wire. It requires braiding an outer layer after the core wire and shielding layer are formed using a braiding machine. For example, utility model patent application CN107359021A discloses a horizontal high-speed cable braiding machine, which includes: a bare cable, braiding machine support feet, a spindle shaft, and a ceramic ball support frame. A braiding machine support leg is located above the support feet, and the machine body is located above the support leg. A bare cable reel frame is located on the upper left end of the machine body, and a bare cable reel is located at the middle of the left end of the cable reel frame. The ceramic ball has low friction, reducing friction in the braided wire, lowering the temperature at the outlet, and preventing wire breakage due to high outlet temperature. Furthermore, a tensioning wheel is installed outside the cable channel tube, ensuring that each braided wire passes through it, resulting in consistent tension and better braiding performance. This also prevents wire breakage due to inconsistent tension, reducing the number of wire breaks during braiding and improving production efficiency.

[0004] However, this existing structure still has the following shortcomings:

[0005] In this technical solution, the distance between the braided cable reel and the cable delivery pipe is too far. During the braiding process, especially during high-speed braiding, the braided pattern is easily bent due to the vibration of the wire, resulting in defective products. This not only affects production efficiency but also wastes resources, and in severe cases, it can even damage the braiding machine.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for preventing vibration and bending of braided yarn.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a device for preventing vibration and bending of braided yarn, comprising: a base on which a yarn conveying pipe is disposed; a traction wheel assembly disposed above the yarn conveying pipe; a yarn passing through the yarn conveying pipe and moved by the traction wheel assembly; multiple sets of braiding spools distributed around the yarn conveying pipe for braiding the yarn; and a double-wheel yarn guide fixture disposed between the yarn conveying pipe and the traction wheel assembly for limiting the yarn to prevent vibration and rotation of the yarn.

[0009] Furthermore, in the above technical solution, a first column is vertically arranged on the base, and a first shaft for installing the double-wheel cable guide fixture is horizontally arranged on the first column, and the first shaft extends to the bottom of the traction wheel assembly.

[0010] Furthermore, in the above technical solution, the dual-wheel wire guide fixture includes: a second shaft disposed on the first shaft, a wire guide wheel clamp disposed in the middle of the second shaft, a first wire guide wheel and a second wire guide wheel respectively disposed at the upper and lower ends of the wire guide wheel clamp in a slidable manner, and a positioning clamp disposed at the lower end of the second shaft for positioning the wire, wherein the positioning clamp has a positioning hole for the wire to pass through.

[0011] Furthermore, in the above technical solution, the upper and lower ends of the wire guide wheel clamp are respectively provided with a first sliding groove and a second sliding groove. The first wire guide wheel is slidably inserted into the first sliding groove, and the second wire guide wheel is slidably inserted into the second sliding groove.

[0012] Furthermore, in the above technical solution, the traction wheel assembly includes: a first traction wheel located above the wire conveying pipe and used for traction of the wire, and a second traction wheel installed on the first column and used to drive the first traction wheel to rotate.

[0013] Furthermore, in the above technical solution, the size of the first traction wheel is larger than the size of the second traction wheel; the first traction wheel is formed with a first wire-locking groove around its periphery for the wire to pass through, and the second traction wheel is formed with a second wire-locking groove around its periphery for the wire to pass through.

[0014] Furthermore, in the above technical solution, a workbench is provided on the base, and the wire conveying pipe and the braided spool assembly are both disposed on the workbench.

[0015] Furthermore, in the above technical solution, the braided bobbin assembly includes a braiding disc mounted on a workbench and at least two braided bobbins mounted on the braiding disc.

[0016] Furthermore, in the above technical solution, braided yarn is wound on the braided spool, and the braided yarn is used to braid the wire to form a braided layer on the surface of the wire.

[0017] Furthermore, in the above technical solution, the base is also provided with at least four support columns, and the four support columns are provided with top covers for preventing foreign objects; the lower end of the base is provided with at least four feet for supporting the base.

[0018] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: In this utility model, by adding a double-wheel thread guide fixture between the traction wheel assembly and the thread conveying pipe, the double-wheel thread guide fixture is adjustable during high-speed braiding. The double-wheel thread guide fixture can control the thread by changing the distance between the first and second thread guide wheels, thereby suppressing the rotation and vibration of the thread during the take-up process, thus preventing the braided thread pattern from becoming distorted. It is suitable for various braiding equipment. Furthermore, without changing the original structure, it effectively solves the problem of thread vibration, improves production efficiency, avoids resource waste, greatly reduces losses caused by vibration, and extends the service life of the entire machine.

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] See Figures 1 to 5As shown, a device for preventing vibration and bending of braided yarn is provided, comprising: a base 1 on which a yarn conveying pipe 11 is disposed; a traction wheel set 2 disposed above the yarn conveying pipe 11; a yarn 3 passing through the yarn conveying pipe 11 and moved by the traction wheel set 2; multiple sets of braiding spools 4 distributed around the yarn conveying pipe 11 for braiding the yarn 3; and a double-wheel yarn guide fixture 5 disposed between the yarn conveying pipe 11 and the traction wheel set 2 for limiting the yarn 3 to prevent vibration and rotation of the yarn 3.

[0026] In this invention, a double-wheel thread guide fixture 5 is added between the traction wheel assembly 2 and the thread conveying pipe 11. During high-speed weaving, the double-wheel thread guide fixture 5 is adjustable. It controls the thread 3 by changing the distance between the first thread guide wheel 53 and the second thread guide wheel 54, thereby suppressing the rotation and vibration of the thread 3 during take-up. This prevents distortion of the braided thread pattern and is suitable for various weaving equipment. Furthermore, without altering the original structure, it effectively solves the problem of thread vibration, improves production efficiency, avoids resource waste, significantly reduces losses caused by vibration, and extends the overall service life of the machine.

[0027] A first column 110 is vertically mounted on the base 1. A first shaft 111 for mounting the double-wheel thread guide fixture 5 is horizontally mounted on the first column 110, and the first shaft 111 extends below the traction wheel assembly 2. Here, by horizontally mounting the first shaft 111 on the first column 110, the added double-wheel thread guide fixture 5 can be mounted on the first shaft 111 without modifying the original structure of the braiding machine. This method is highly feasible, easy to assemble, and has good adaptability.

[0028] The dual-wheel wire guide fixture 5 includes: a second shaft 52 disposed on the first shaft 111; a wire guide wheel clamp 51 disposed in the middle of the second shaft 52; a first wire guide wheel 53 and a second wire guide wheel 54 slidably disposed at the upper and lower ends of the wire guide wheel clamp 51; and a positioning clamp 55 disposed at the lower end of the second shaft 52 for positioning the wire 3. The positioning clamp 55 has a positioning hole 551 for the wire 3 to pass through. Here, in conjunction with... Figure 4As shown, it can be understood that the first guide roller 53 and the second guide roller 54 are respectively located on the left and right sides of the wire 3, and together they generate a clamping force on the wire 3 to prevent excessive rotation and vibration of the wire 3. When the equipment is performing high-speed braiding, the distance between the first guide roller 53 and the second guide roller 54 can be adjusted. When the rotation and vibration of the wire 3 are large and will affect the braiding, the first guide roller 53 and the second guide roller 54 can be brought closer together to reduce the distance and increase the clamping force, thereby reducing the rotation and vibration of the wire 3. When the clamping force between the first guide roller 53 and the second guide roller 54 is too large, and the rotation and vibration of the wire 3 are small and will not affect the braiding, the distance between the first guide roller 53 and the second guide roller 54 can be appropriately increased to reduce the clamping force and ensure normal braiding.

[0029] The wire guide wheel clamp 51 has a first groove 511 and a second groove 512 at its upper and lower ends, respectively. The first wire guide wheel 53 is slidably inserted into the first groove 511, and the second wire guide wheel 54 is slidably inserted into the second groove 512. Here, both the first groove 511 and the second groove 512 are arranged laterally. The first wire guide wheel 53 and the second wire guide wheel 54 slide laterally along the first groove 511 and the second groove 512, respectively, to clamp the wire 3 in the middle and ensure that it does not vibrate excessively.

[0030] The traction wheel assembly 2 includes: a first traction wheel 21 located above the wire conveying pipe 11 for traction of the wire 3, and a second traction wheel 22 mounted on the first column 110 for driving the first traction wheel 21 to rotate. Here, the traction wheel assembly 2 is located above the wire conveying pipe 11, and it not only needs to pull the wire 3 out of the wire conveying pipe 11, but also needs to control the braiding tension at an appropriate speed. The tension will affect the braiding pattern and the three-dimensional effect of the texture.

[0031] The first traction wheel 21 is larger than the second traction wheel 22. The first traction wheel 21 has a first wire-locking groove 211 formed around its circumference for the wire 3 to pass through, and the second traction wheel 22 has a second wire-locking groove 212 formed around its circumference for the wire 3 to pass through. Here, the first wire-locking groove 211 and the second wire-locking groove 212 effectively prevent the wire 3 from tangling during high-speed operation, avoiding the situation where the wire 3 becomes stuck after tangling.

[0032] A workbench 120 is provided on the base 1, and the wire conveying pipe 11 and the braiding spool assembly 4 are both disposed on the workbench 120. The braiding spool assembly 4 includes a braiding disc 41 mounted on the workbench 120 and at least two braiding spools 42 mounted on the braiding disc 41. Braiding thread 421 is wound on the braiding spools 42, and the braiding thread 421 is used to braid the wire 3 through the braiding spools 42 to form a braided layer 30 on the surface of the wire 3.

[0033] The base 1 is also provided with at least four support columns 130, and the four support columns 130 are provided with top covers 140 for preventing foreign objects; the lower end of the base 1 is provided with at least four foot legs 150 for supporting the base 1.

[0034] In summary, this invention adds a double-wheel thread guide fixture 5 between the traction wheel assembly 2 and the thread conveying pipe 11. During high-speed braiding, the double-wheel thread guide fixture 5 is adjustable. It controls the thread 3 by changing the distance between the first thread guide wheel 53 and the second thread guide wheel 54, thus suppressing the rotation and vibration of the thread 3 during take-up. This prevents distortion of the braided thread pattern and is suitable for various braiding equipment. Furthermore, without altering the original structure, it effectively solves the problem of thread vibration, improves production efficiency, avoids resource waste, significantly reduces losses caused by vibration, and extends the overall service life of the machine.

All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
