Description

Technical Field

[0001] This utility model relates to the field of tension adjustment, and in particular to a tension adjustment device for textiles. Background Technology

[0002] With the increasing speed and automation of textile machinery, the requirements for tension stability have increased significantly. Traditional methods rely on workers to manually adjust the pressure based on experience, resulting in large and unstable tension fluctuations, leading to high scrap rates and low production efficiency. Using a tension adjustment machine can stabilize the processing, reduce waste, and ensure that the finished products have consistent dimensions and smooth surfaces, thus meeting quality requirements.

[0003] Existing textile tension adjustment equipment uses the height of the adjusting roller to achieve tension control. The tension is adjusted by changing the contact distance between the roller and the fabric and the length of the stretching path. When the roller is raised, the fabric is stretched and the tension increases. When the roller is lowered, the fabric relaxes and the tension decreases. However, this type of equipment has significant limitations. The adjustment distance is limited by the mechanical structure and is a fixed range. It can only achieve step-like adjustment and cannot precisely adjust the fabric. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a textile tension adjustment device, which aims to improve the problem that stepped adjustment cannot accurately adjust the tension of textiles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a textile tension adjustment device, comprising a base plate, a plurality of support rods mounted on the top of the base plate, a square groove and a positioning hole formed on the outer wall of the support rods, an adjustment rod provided on the inner wall of the support rods, adjustment holes evenly distributed on the outer wall of the adjustment rods, a pin slidably connected to the inner wall of the adjustment rods, a first spring fixedly connected to one end of the pin, a rotating arm fixedly connected to one end of the adjustment rods, a rotating column provided on adjacent sides of the plurality of rotating arms, screws provided on the outer wall of the support rods, and auxiliary components provided on the top of the base plate.

[0006] The above technical solution involves: removing the screw to release the fixing position of the adjusting rod; manually pushing it to disengage the pin from the positioning hole; manually adjusting the height of the adjusting rod until it reaches the approximate position; the first spring pushing the pin to automatically insert it into the positioning hole; and then manually rotating the rotating arm to drive the rotating column, thereby precisely adjusting the tension of the fabric.

[0007] Preferably, the auxiliary component includes a support block, one end of which is fixedly connected to the top of the base plate. The base plate has a plurality of second springs inside, one end of which is fixedly connected to a fixing column. The outer wall of the fixing column is rotatably connected to a roller.

[0008] Preferably, the two ends of the rotating column are rotatably connected to the inner wall of the rotating arm.

[0009] Preferably, the pin is slidably connected to the surface of the positioning hole.

[0010] Preferably, the outer wall of the adjusting rod is slidably connected to the inner wall of the square groove.

[0011] Preferably, the screw passes through the support rod and is inserted into the adjustment hole.

[0012] Preferably, one end of the first spring is fixedly connected to the inner wall of the adjusting rod.

[0013] Preferably, the outer wall of the fixed column is slidably connected to the inner wall of the support block, and one end of the second spring is fixedly connected to the inner wall of the support block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by pulling out the screw, the position of the adjusting rod is released. The pin can be disengaged from the positioning hole by manually pushing it. When the height of the adjusting rod is adjusted manually and it reaches the approximate position, the first spring pushes the pin to automatically insert into the positioning hole. Then, the rotating arm is manually rotated, which drives the rotating column to move, thereby precisely adjusting the tension of the fabric.

[0015] 2. In this utility model, the second spring compresses the fixing column to make the fixing column move, and the fixing column drives the rollers to move relative to each other, so that the rollers are always in a state of compression, thereby fixing the fabric and preventing the fabric from slipping off.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-3 An embodiment of this utility model provides a textile tension adjustment device, comprising a base plate 1, a plurality of support rods 2 mounted on the top of the base plate 1, a square groove 3 and a positioning hole 4 formed on the outer wall of the support rods 2, an adjustment rod 5 provided on the inner wall of the support rods 2, adjustment holes 6 evenly distributed on the outer wall of the adjustment rods 5, a pin 7 slidably connected to the inner wall of the adjustment rods 5, a first spring 8 fixedly connected to one end of the pin 7, a rotating arm 9 fixedly connected to one end of the adjustment rods 5, a rotating column 10 provided on the adjacent side of the plurality of rotating arms 9, screws 15 provided on the outer wall of the support rods 2, and an auxiliary component provided on the top of the base plate 1.

[0020] Specifically, the two support rods 2 installed at the top provide support for the overall height adjustment parts, and the first spring 8 fixes the position of the pin 7 to prevent the pin 7 from dislodging from the inner wall of the adjustment rod 5 due to the spring force.

[0021] Reference Figures 4-5 The auxiliary components include a support block 11, one end of which is fixedly connected to the top of the base plate 1. The base plate 1 has a plurality of second springs 12 inside, one end of which is fixedly connected to a fixing column 13. The outer wall of the fixing column 13 is rotatably connected to a roller 14.

[0022] Specifically, the second spring 12, utilizing its own elastic restoring characteristics, can continuously apply a relative elastic thrust to the corresponding fixed post 13. This thrust is smoothly transmitted to the roller 14 connected to it through the fixed post 13. With the help of this continuous and stable elastic force, it can be ensured that the two opposing rollers 14 always maintain a tight mutual compression state. When the fabric passes between the two rollers 14, the compression action of the rollers 14 can reliably clamp and fix the fabric, effectively preventing the fabric from shifting or loosening due to external disturbances or its own deformation during transmission and processing. This ensures that the fabric is always within the preset tension range, providing a stable material state for subsequent cutting, sewing, printing and dyeing processes, and ensuring processing accuracy and finished product quality.

[0023] Reference Figure 2 The two ends of the rotating column 10 are rotatably connected to the inner wall of the rotating arm 9.

[0024] Specifically, the rotating column 10 is assembled to the inner wall of the rotating arm 9 through a rotating connection structure, and the two form a flexible rotatable fit. When the fabric comes into contact with the surface of the rotating column 10 in the transmission path and generates relative movement, the rotating column 10 can rotate synchronously with the conveying direction of the fabric, transforming the original sliding friction between the fabric and the rotating column 10 into smoother rolling friction, which greatly reduces the frictional resistance in the fabric conveying process.

[0025] Reference Figure 1 The pin 7 is slidably connected to the surface of the positioning hole 4.

[0026] Specifically, the pin 7 and the positioning hole 4 adopt a precise plug-in mating structure. The even distribution of the positioning holes 4 provides multiple adjustment positions for the adjustment of the position of the adjustment rod 5. When it is necessary to fix the adjustment rod 5, the first spring 8 pushes the pin 7 to be precisely inserted into the corresponding positioning hole 4. Through the tight fit between the pin 7 and the positioning hole 4, the adjustment rod 5 can be reliably limited axially and fixed radially.

[0027] Reference Figure 1 The outer wall of the adjusting rod 5 is slidably connected to the inner wall of the square groove 3.

[0028] Specifically, the square groove 3 adopts a rectangular cavity structure that is compatible with the adjusting rod 5. Its inner wall is precision machined to form a regular and smooth guide contact surface. The square groove 3 provides a clear movement channel for the adjusting rod 5, which can accurately guide the movement direction of the adjusting rod 5. The rectangular cross-sectional profile of the square groove 3 is precisely matched with the shape of the adjusting rod 5, which can effectively limit the adjusting rod 5 from the left and right sides in the horizontal direction.

[0029] Reference Figure 1 Screw 15 passes through support rod 2 and is inserted into adjustment hole 6.

[0030] Specifically, the screw 15 has its shank passing through the pre-set mounting hole on the support rod 2 and inserted into the adjustment hole 6. It achieves reliable locking through the precise engagement of the screw thread with the inner wall of the adjustment hole 6.

[0031] Reference Figure 3 One end of the first spring 8 is fixedly connected to the inner wall of the adjusting rod 5.

[0032] Specifically, the first spring 8 is firmly connected to the inner wall of the adjusting rod 5 through the fixing structure at both ends. This not only precisely defines the installation position of the first spring 8 inside the adjusting rod 5, but also provides reliable positioning support for the pin 7 through the matching assembly relationship between the first spring 8 and the pin 7.

[0033] Reference Figure 5The outer wall of the fixed column 13 is slidably connected to the inner wall of the support block 11, and one end of the second spring 12 is fixedly connected to the inner wall of the support block 11.

[0034] Specifically, the outer wall of the fixed column 13 and the inner wall of the support block 11 form a smooth sliding fit structure, which can ensure that the fixed column 13 can move stably along the inner wall of the support block 11 without jamming or displacement.

[0035] Working principle: During operation, the fabric passes through roller 14, rests on the outer wall of rotating column 10, and then exits through another roller 14. The second spring 12 compresses the fixing column 13, causing it to move. The fixing column 13 drives the roller 14 to move relative to each other, thus fixing the fabric. By pulling out the screw 15, the position of the adjusting rod 5 is released. By manually pushing it, the pin 7 can be disengaged from the positioning hole 4. By manually adjusting the height of the adjusting rod 5, when it reaches the approximate position, the first spring 8 pushes the pin 7 to automatically insert into the positioning hole 4. Then, the rotating arm 9 is manually rotated, which drives the rotating column 10 to move, thereby precisely adjusting the tension of the fabric. After adjustment, the adjusting position is fixed by inserting the screw 15 into the adjusting hole 6.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
