Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a tension adjusting roller. Background Art

[0002] A weaving machine is a machine that combines yarns into cloth, and is used to make grey cloth or finished cloth from the yarns made in the spinning department through processes such as weaving preparation, weaving, and finishing. It mainly includes two systems of yarns, namely warp yarns and weft yarns, and these two systems of yarns are interwoven on the loom according to certain rules to form products. There are many types of weaving machinery, which are mainly divided into two categories: shuttle looms and shuttleless looms. Shuttle looms use shuttles to carry weft yarns through warp yarns, while shuttleless looms introduce weft yarns into the loom for weaving through other methods (such as jet, rapier, projectile, etc.). The development of weaving machinery has experienced the evolution from primitive looms to modern mechanical looms. The primitive loom is a simple textile tool, using wooden sticks and manual operations, while modern mechanical looms are operated by mechanical power, greatly improving production efficiency and the quality of fabrics. With the development of technology, weaving machinery has not only been improved in structure, but also innovated in function to meet different textile needs. The auxiliary equipment of weaving machinery is also very important, including warping machines, sizing machines, etc. These equipment are used to prepare yarns to make them suitable for use on the loom. The warping machine arranges the yarns on the warp beam according to certain rules, while the sizing machine coats a layer of sizing agent on the surface of the yarns to increase the strength and wear resistance of the yarns. The existence of these equipment ensures the normal operation of the weaving machinery and the production of high-quality products.

[0003] Most commonly used weaving machines are unable to adjust the tension of the yarns. If the tension of the yarns is too small, it is easy to cause accumulation, reducing the flatness of the finished cloth. If the tension of the yarns is too large, it is easy to cause the finished cloth to shrink and even break the yarns. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a tension adjusting roller to solve the problem that the weaving machine in the related technology cannot adjust the tension of the yarns, resulting in a decrease in the flatness of the finished cloth and even breaking the yarns.

[0005] To achieve the above purpose, according to one aspect of the utility model, a tension adjusting roller is provided, which includes a base and a weaving part, and further includes: a yarn feeding part, which is fixedly arranged on the upper part of one end of the base and releases yarns outward for the weaving part to weave.

The adjustment group is arranged on the upper part of one end of the base and is located at the same end as the winding group. The adjustment group is used to adjust the tension of the finished fabric. When the tension of the finished fabric is too small, the adjustment group moves upward to extend the path of the fabric and increase its tension. When the tension of the finished fabric is too large, the adjustment group moves downward to reduce the path of the fabric and reduce its tension.

[0007] Further, the winding group includes two first brackets, a winding roller and a guiding roller. The first brackets are respectively fixedly arranged on both sides of the base. The first brackets are both provided with bracket holes, and both sides of the bracket holes are provided with a plurality of sliding grooves.

[0008] Further, the winding roller is arranged between the two first brackets and can rotate along the first brackets. A power source is fixedly arranged at one end of the winding roller for driving the winding roller to rotate. The power source is fixedly arranged inside the first bracket.

[0010] Further, the adjustment group includes an adjustment roller and two adjustment parts. The adjustment roller is rotationally connected to the adjustment parts and is located between the winding roller and the guiding roller. The adjustment parts are respectively arranged in the bracket holes of the first brackets on both sides and can move up and down along the bracket holes.

[0011] Further, the adjustment part includes a connection group, a sliding group and a roller. The sliding group pulls the roller to move up and down. The sliding group restricts the roller to move up and down along the sliding groove in the bracket hole.

[0012] Further, the roller includes an outer wheel, an inner wheel, a plurality of annular grooves and a plurality of balls. The inner wheel is concentrically arranged inside the outer wheel. A plurality of annular grooves are arranged on both the inner ring of the outer wheel and the outer ring of the inner wheel, and the annular grooves on the inner ring of the outer wheel and the outer ring of the inner wheel correspond one by one. The balls are all arranged to roll in the annular grooves so that the outer wheel and the inner wheel can rotate relative to each other. Both ends of the adjustment roller are fixedly connected to the inner wheel.

[0013] Further, the sliding group includes two slider plates and a plurality of ribs. The slider plates are respectively fixedly arranged on both sides of the outer wheel. A plurality of ribs are fixedly arranged on the outer surfaces of the slider plates. The ribs can slide up and down along the sliding grooves.

[0014] Further, the connecting group includes a first fixing block, a spring, and a second fixing block. The first fixing block is fixedly connected to the inner wheel.

[0016] Compared with the prior art, the utility model has the following beneficial effects: when the tension of the fabric is too small, the downward pressure of the fabric on the adjusting roller also decreases correspondingly, and it cannot offset the pulling force of the spring. The spring contracts, driving the roller to move upward. The distance between the adjusting roller and the winding roller and the guiding roller becomes larger and larger, and the path of the fabric from the guiding roller to the winding roller becomes longer and longer, and its tension also increases accordingly. When the tension of the fabric balances with the pulling force of the spring, the roller stops rising, keeping the fabric tension at a normal value; when the tension of the fabric is too large, the downward pressure of the fabric on the adjusting roller also increases correspondingly, being greater than the pulling force of the spring. The adjusting roller drives the roller to move downward, and the path of the fabric from the guiding roller to the winding roller becomes shorter and shorter, and its tension also decreases accordingly. When the tension of the fabric balances with the pulling force of the spring, the roller stops descending, keeping the fabric tension at a normal value. Description of the Drawings

Detailed implementation mode

[0028] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation mode, structure, features and their effects of the present utility model as follows.

[0029] Please refer to Figures 1 to 6 , this embodiment provides a tension adjusting roller, which includes a base 1 and a weaving section 2, and further includes: a yarn feeding section 3, which is fixedly arranged on the upper part of one end of the base 1 and releases yarn outward for the weaving section 2 to weave;

[0030] A weaving and winding section 4, the weaving and winding section 4 includes an adjusting group and a winding group. The winding group is fixedly arranged on the upper part of the other end of the base 1, and the winding group winds up the finished fabric woven by the weaving section 2. The adjusting group is arranged on the upper part of one end of the base 1 and is located at the same end as the winding group. The adjusting group is used to adjust the tension of the finished fabric. When the tension of the finished fabric is too small, the adjusting group moves upward to extend the path of the fabric and increase its tension. When the tension of the finished fabric is too large, the adjusting group moves downward to reduce the path of the fabric and reduce its tension.

[0031] The winding group includes two first supports 41, a winding roller 42 and a guide roller 44. The first supports 41 are respectively fixedly arranged on both sides of the base 1.

One end of the guide roller 44 is fixedly provided with a power source. In this embodiment, a motor is preferably used as the power source, which is simple and easy to operate and is used to drive the guide roller 44 to rotate. The power source is fixedly arranged inside the first support 41. The guide roller 44 flattens the fabric to prevent the fabric from being skewed and wound around the winding roller 42, affecting the flatness of the finished fabric.

[0034] The adjusting group includes an adjusting roller 43 and two adjusting parts 45. The adjusting roller 43 is rotatably connected to the adjusting parts 45 and is located between the winding roller 42 and the guiding roller 44. The adjusting parts 45 are respectively arranged in the support holes 411 of the first support 41 on both sides and can move up and down along the support holes 411.

[0035] The adjusting part 45 includes a connecting group, a sliding group and a roller 456. The sliding group pulls the roller 456 to move up and down, and the sliding group restricts the roller 456 to move up and down along the chute 412 in the support hole 411.

[0036] The roller 456 includes an outer wheel 4561, an inner wheel 4562, a plurality of annular grooves 4563 and a plurality of balls 4564. The inner wheel 4562 is concentrically arranged inside the outer wheel 4561. A plurality of annular grooves 4563 are provided on both the inner ring of the outer wheel 4561 and the outer ring of the inner wheel 4562, and the annular grooves 4563 on the inner ring of the outer wheel 4561 and the outer ring of the inner wheel 4562 correspond to each other one by one. The balls 4564 are all arranged to roll in the annular grooves 4563, so that the outer wheel 4561 and the inner wheel 4562 can rotate relative to each other. Both ends of the adjusting roller 43 are fixedly connected to the inner wheel 4562.

[0037] The sliding group includes two slider 454 and a plurality of ribs 455. In this embodiment, three ribs 455 are preferably provided, which are equal in number to the number of chutes 412. Each rib 455 corresponds to one chute 412. The sliders 454 are respectively fixedly arranged on both sides of the outer wheel 4561. A plurality of ribs 455 are fixedly arranged on the outer surfaces of the sliders 454, and the ribs 455 can slide up and down along the chutes 412.

[0038] The connecting group includes a first fixing block 451, a spring 452 and a second fixing block 453. The first fixing block 451 is fixedly connected to the inner wheel 4562. The second fixing block 453 is fixedly arranged on the outside of the first support 41 and is located above the support hole 411. One end of the spring 452 is fixedly connected to the first fixing block 451, and the other end is fixedly connected to the second fixing block 453.

[0039] The weaving part 2 is fixedly arranged on the upper surface of the base 1 and is located between the yarn feeding part 3 and the winding and weaving part 4, and weaves the yarn released by the yarn feeding part 3 into cloth.

[0040] Start the motors inside the second support 32 and the first support 41 simultaneously. The motors drive the unwinding roller 31 and the winding roller 42 to rotate respectively. The unwinding roller 31 releases the yarn outward. After passing through the weaving section 2, the yarn is woven into fabric. The fabric passes under the guiding roller 44 and is guided and flattened by it to prevent the fabric from skewing and winding around the winding roller 42, which affects the flatness of the finished fabric. The fabric passes under the guiding roller 44 and then bypasses above the adjusting roller 43, and then winds around the winding roller 42 and is wound and stored by the winding roller 42. When the winding speed decreases and the tension of the fabric is too small, the downward pressure of the fabric on the adjusting roller 43 also decreases correspondingly and cannot offset the pulling force of the spring 452. The spring 452 contracts, pulls the roller 456 upward through the first fixing block 451, and the rib 455 moves upward along the chute 412. The chute 412 guides the adjusting part 45 to prevent the roller 456 from shifting out of the chute 412 when moving, resulting in the skewing of the adjusting roller 43 and causing the fabric to not be wound flatly around the winding roller 42 and generate wrinkles. As the roller 456 moves upward, the distances between the adjusting roller 43 and the winding roller 42 and the guiding roller 44 become larger and larger, and the path of the fabric from the guiding roller 44 to the winding roller 42 also becomes longer and longer, and its tension also increases accordingly. When the tension of the fabric balances with the pulling force of the spring 452, the roller 456 stops rising, maintaining the fabric tension at a normal value. When the tension of the fabric is too large, the downward pressure of the fabric on the adjusting roller 43 also increases correspondingly and is greater than the pulling force of the spring 452. The adjusting roller 43 drives the roller 456 to move downward, the spring 452 elongates, the distances between the adjusting roller 43 and the winding roller 42 and the guiding roller 44 become smaller and smaller, and the path of the fabric from the guiding roller 44 to the winding roller 42 also becomes shorter and shorter, and its tension also decreases accordingly. When the tension of the fabric balances with the pulling force of the spring 452, the roller 456 stops descending, maintaining the fabric tension at a normal value.

[0041] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
