Abstract
Description
Technical Field
[0001] This utility model relates to the field of covering yarn machine technology, specifically a covering yarn machine with a tension adjustment device. Background Technology
[0002] A covering yarn machine is a device used to produce covered yarn, a new type of yarn with a core of filament or staple fiber wrapped with another type of filament or staple fiber. The outer filament is continuously rotated and wound around the uniformly drawn core filament spandex, and twisted to give it twist. The outer filament and spandex filament are simultaneously drawn through a nozzle of a specific type, and rhythmically sprayed with high-compressed air to form a rhythmic network of dots. According to the number of covering layers, it can be divided into single-covering yarn machines and double-covering yarn machines. Single-covering yarn machines are suitable for producing single-covered yarns such as nylon-spandex and polyester-spandex; double-covering yarn machines can produce double-covered yarns with higher covering strength and stability.
[0003] Existing yarns are affected by various factors during processing, such as uneven yarn thickness and changes in friction of yarn guiding components. However, traditional covering yarn machines lack an effective tension adjustment mechanism, leading to unstable quality of covered yarns. Utility Model Content

[0006] Support legs fixedly installed at the bottom of the fixed plate;
[0007] A column fixedly installed on top of the fixing plate;
[0008] And a tension adjustment assembly disposed at the top of the fixed plate;
[0009] The tension adjustment assembly includes an adjustment mechanism disposed at the top of the fixed plate;
[0010] A guide mechanism is provided at the top of the fixed plate, and the guide mechanism is connected to the adjustment mechanism.
[0011] Preferably, a processing table is fixedly installed on the top of the column, a stabilizing column is fixedly installed on the top of the processing table, and a top plate is fixedly installed on the top of the stabilizing column.
[0012] Preferably, the adjusting mechanism includes a hydraulic cylinder, which is fixedly installed on the top of the processing table. An adjusting block is fixedly installed on the hydraulic cylinder via a hydraulic rod at its output end. A slide rod is slidably installed on the inner wall of the adjusting block, which has an arc-shaped groove. A displacement block is fixedly installed at one end of the slide rod. A long rod is slidably installed on the inner wall of the displacement block. One end of the long rod is fixedly connected to the inner wall of the stabilizing column. A tension adjusting roller is fixedly installed at the other end of the displacement block.
[0013] Preferably, there are two hydraulic cylinders, both of which are of equal shape and size, and are symmetrically arranged with respect to the center plane of the processing table in the left-right direction.
[0014] Preferably, the guiding mechanism includes a sleeve ring and a mounting plate. The sleeve ring is fixedly installed on the front of the processing table, and the mounting plate is fixedly installed on the top of the processing table. A guide roller one is rotatably mounted on the inner wall of the mounting plate via a bearing, and a guide roller two is rotatably mounted on the inner wall of the mounting plate via a bearing.
[0015] Preferably, the second guide roller is located above the first guide roller, and a yarn is disposed in contact with the side wall of the second guide roller. The side wall of the yarn is in contact with the side wall of the first guide roller, the side wall of the yarn is in contact with the inner wall of the sleeve ring, and the side wall of the yarn is in contact with the side wall of the tension adjusting roller.
[0016] Preferably, there are four support legs, all of which are of the same shape and size. The four support legs are fixedly installed at the four bottom corners of the fixed plate, and the support legs can support the position of the entire device.
[0017] This invention provides a covering yarn machine with a tension adjustment device. It has the following advantages:
[0018] (1) When the operator needs to adjust the tension of the yarn, the hydraulic cylinder can be opened directly. The hydraulic cylinder drives the position of the adjusting block to be raised through the hydraulic rod at the output end. The arc groove opened on the inner wall of the adjusting block will squeeze the side wall of the slide rod. The slide rod will drive the displacement block to slide on the side wall of the long rod. The displacement block will further drive the tension adjusting roller to move to the rear position, effectively squeezing the side wall of the yarn, thereby realizing the adjustment of the yarn tension. This solves the problem that the existing yarn is affected by a variety of factors during the processing, such as uneven yarn thickness and changes in the friction of the yarn guiding parts. However, the traditional covering yarn machine lacks an effective tension adjustment mechanism, resulting in unstable quality of the covered yarn.
[0019] (2) In this utility model, the operator passes one end of the yarn through the inner wall of the sleeve ring from bottom to top, contacts the inner walls of guide roller one and guide roller two, then connects to the side wall of the tension adjusting roller, and then connects to the winding end of the covering yarn machine. The sleeve ring, mounting plate and guide roller one can effectively guide the position of the yarn, prevent the yarn from getting tangled, and make it easier for the operator to use the device.

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0026] Example 1: A preferred embodiment of the covering yarn machine with tension adjustment device provided by this utility model is as follows: Figures 1 to 4 As shown: A covering yarn machine with a tension adjustment device includes a fixed plate 1.
[0027] The support legs 2 are fixedly installed at the bottom of the fixed plate 1. There are four support legs 2, and the four support legs 2 are all the same in shape and size. The four support legs 2 are fixedly installed at the four corners of the bottom of the fixed plate 1. The support legs 2 can support the position of the entire device.
[0028] A column 3 is fixedly installed on the top of the fixed plate 1. A processing table 5 is fixedly installed on the top of the column 3. A stabilizing column 6 is fixedly installed on the top of the processing table 5. A top plate 7 is fixedly installed on the top of the stabilizing column 6.
[0029] And a tension adjustment assembly 4 is installed at the top of the fixed plate 1;
[0030] The tension adjustment assembly 4 includes an adjustment mechanism 41 disposed at the top of the fixed plate 1;
[0031] A guide mechanism 42 is provided at the top of the fixed plate 1, and the guide mechanism 42 is connected to the adjustment mechanism 41.
[0032] The adjustment mechanism 41 includes a hydraulic cylinder 412, which is fixedly installed on the top of the processing table 5. An adjustment block 411 is fixedly installed on the hydraulic cylinder 412 via a hydraulic rod at the output end. A slide rod 413 is slidably installed on the inner wall of the adjustment block 411, which has an arc-shaped groove. A displacement block 414 is fixedly installed on one end of the slide rod 413. A long rod 416 is slidably installed on the inner wall of the displacement block 414. One end of the long rod 416 is fixedly connected to the inner wall of the stabilizing column 6. A tension adjustment roller 415 is fixedly installed on the other end of the displacement block 414.
[0033] In this embodiment, there are two hydraulic cylinders 412. The two hydraulic cylinders 412 are of equal shape and size and are symmetrically arranged with respect to the center plane of the processing table 5 in the left-right direction.
[0034] In the specific implementation process, when the operator needs to adjust the tension of the yarn 422, the hydraulic cylinder 412 can be opened directly. The hydraulic cylinder 412 drives the position of the adjusting block 411 to be raised through the hydraulic rod at the output end. The arc groove opened on the inner wall of the adjusting block 411 will squeeze the side wall of the slide rod 413. The slide rod 413 will drive the displacement block 414 to slide on the side wall of the long rod 416. The displacement block 414 will further drive the tension adjusting roller 415 to move to the rear position, effectively squeezing the side wall of the yarn 422, thereby realizing the adjustment of the tension of the yarn 422 (the controller can control the two hydraulic cylinders 412 to open and close simultaneously).
[0035] Example 2: Based on Example 1, a preferred embodiment of the covering yarn machine with a tension adjustment device provided by this utility model is as follows: Figures 1 to 4 As shown: The guide mechanism 42 includes a sleeve ring 421 and a mounting plate 423. The sleeve ring 421 is fixedly installed on the front of the processing table 5, and the mounting plate 423 is fixedly installed on the top of the processing table 5. A guide roller 424 is rotatably mounted on the inner wall of the mounting plate 423 through a bearing, and a guide roller 425 is rotatably mounted on the inner wall of the mounting plate 423 through a bearing.
[0036] In this embodiment, the second guide roller 425 is located above the first guide roller 424. The side wall of the second guide roller 425 is in contact with the yarn 422. The side wall of the yarn 422 is in contact with the side wall of the first guide roller 424. The side wall of the yarn 422 is in contact with the inner wall of the sleeve ring 421. The side wall of the yarn 422 is in contact with the side wall of the tension adjusting roller 415.
[0037] In the specific implementation process, when the operator uses the device, one end of the yarn 422 passes through the inner wall of the sleeve ring 421 from bottom to top, contacts the inner walls of the first guide roller 424 and the second guide roller 425, and then connects to the side wall of the tension adjusting roller 415, and then connects to the winding end of the covering yarn machine (the winding end of the covering yarn machine is existing publicly available technology, so it is not shown or described in detail in the figure). The sleeve ring 421, the mounting plate 423 and the first guide roller 424 can effectively guide the position of the yarn 422 and prevent the yarn 422 from getting tangled.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
