Description

Technical Field

[0001] This utility model relates to the technical field of tension-regulating fixtures for raw material fabrics used in garment processing, specifically a tension-regulating fixture for raw material fabrics used in garment processing. Background Technology

[0002] If the tension of the raw fabric is unstable during a series of processing steps such as cutting, sewing, printing, dyeing, and embroidery, it can easily cause many problems. For example, uneven tension during the cutting process can lead to deviations in the fabric cutting size, making it difficult for the subsequent sewn garment parts to match accurately, thus affecting the overall pattern and wearing effect of the garment.

[0003] Currently, according to the publication number CN218476566U, an adjustable textile raw material fabric processing fixture relates to the field of raw material fabric processing technology. The adjustable textile raw material fabric processing fixture includes a base with a sliding groove inside and a sliding hole at the top. Multiple sliders are movably connected inside the sliding groove, and each slider has an electric lifting rod fixedly connected to its top. Springs are provided on both sides of the electric lifting rod, and a first pressure plate is fixedly connected to the top of each electric lifting rod. A motor is located on one side of the base, and a threaded rod is fixedly connected to the output end of each motor, with the threaded rod fixedly connected to the slider. This utility model, through the interaction of the base with the sliding groove and sliding hole, the sliders adapted to the sliding groove, the first pressure plate fixedly connected to the top of the sliders via the electric lifting rod, and the threaded rods fixedly connected to the output end of the motor and screwed to the sliders, allows the fixture to adjust the distance between the clamps according to the size of the textile raw material fabric, enhancing the practicality of the fixture.

[0004] The aforementioned adjustable textile raw material processing fixture has some problems in actual use. Excessive downward pressure during cutting can cause the raw material to be squeezed and deformed, generating additional tensile force, which may lead to the deviation of the raw material.

[0009] As a preferred technical solution, the U-shaped frame has limiting holes on both sides that are set along the height. Each set of limiting holes has a limiting post slidably connected to its inner cavity. The opposite ends of the two sets of limiting posts are respectively fixedly connected to the corresponding side ends of the pressure strip.

[0010] As a preferred technical solution, the second clamping member includes a square ring with a sliding seat top fixedly installed. A pressure plate is slidably connected to the inner cavity of the square ring. Connecting rods are fixedly connected to both ends of the pressure plate. The tops of the two sets of connecting rods pass through the square ring upwards. A connecting strip is fixedly connected to the tops of the two sets of connecting rods. A fixing bolt is fixedly installed on the top of the square ring. The end of the fixing bolt passes through the connecting strip upwards. An adjusting nut is threadedly connected to the end of the fixing bolt located on the upper part of the connecting strip. The bottom of the adjusting nut contacts the top of the connecting strip. A second spring is sleeved on the surface of the two sets of connecting rods located above the connecting strip. The two ends of the two sets of second springs contact the bottom of the corresponding side connecting strip and the top of the square ring, respectively.

[0011] As a preferred technical solution, the movable component includes sliding grooves formed on the lower inner walls of the front and rear sides of the square hole. Guide bars are slidably connected to the inner cavities of the two sets of sliding grooves. The top of the guide bar is fixedly connected to the bottom of the sliding ring, and a handle is fixedly connected to the bottom of the guide bar. Anti-deviation components are provided on both sides of the guide bar to fix the guide bar and prevent it from deviating.

[0012] As a preferred technical solution, the anti-deviation component includes a limiting groove formed at the bottom of the support platform and located at the corresponding position of each set of sliding grooves. The inner cavity of each set of limiting grooves is connected to the inner cavity of the corresponding side sliding groove.

The ends of the two sets of limiting bolts pass downward through the inner cavity of the corresponding side limiting groove. Limiting nuts are threadedly connected to the ends of the two sets of limiting bolts. The tops of the two sets of limiting nuts contact the bottom of the support platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of the first spring and the sliding seat, the sliding ring and the sliding seat cooperate with the first spring to make the second clamping member drive the fabric to tighten, ensuring the fabric is flat. In addition, during cutting, the elastic deformation of the first spring can absorb part of the pressure of the cutting tool, offset the instantaneous thrust, avoid the fabric from being squeezed and deformed due to local high pressure, improve the cutting accuracy, and effectively prevent the raw material fabric from shifting.

[0016] 2. This utility model, through the setting of the moving part, allows the sliding ring to move smoothly through the sliding cooperation between the slide groove and the guide bar. Furthermore, the position of the sliding ring can be easily adjusted by pushing the guide bar with the handle, thereby adjusting the compression of the first spring and thus increasing the elastic potential energy of the first spring. The higher the elastic potential energy of the first spring, the stronger its ability to absorb external forces. When the cutter presses down, a greater amount of compression can absorb more cutting pressure through the elastic deformation of the spring, reducing the rigid compression of the raw material layout part.

[0017] 3. This utility model uses a scale bar and a pointer to form a visual adjustment indicator. When the sliding ring is pushed, the pointer points to the scale bar, which can accurately locate the movement distance of the sliding ring, thereby quantifying the compression of the first spring. At the same time, the operator can intuitively control the tension of the fabric and the spring buffer force according to the scale value, which improves the accuracy and controllability of the operation and makes it easier to adapt to different cutting process requirements.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-3This embodiment provides a tension-constant adjusting fixture for raw fabric used in garment processing, including a support platform 100. A first clamping member for clamping the fabric is provided on the upper left side of the support platform 100, and a second clamping member for clamping the other end of the fabric is provided on the upper right side of the support platform 100. A square hole 101 is formed at the top right side of the support platform 100, extending along the length of the support platform 100. A round rod 500 is fixedly connected to the inner cavity of the square hole 101. A sliding ring 506 is slidably fitted on the left end of the round rod 500, and a sliding seat 400 is slidably fitted on the right end of the round rod 500. The surface of the round rod 500 located between the sliding ring 506 and the sliding seat 400... A first spring 501 is fitted on the sliding seat 400, and the top of the sliding seat 400 is fixedly connected to the bottom of the second clamping member. A movable member is provided at the bottom of the sliding ring 506. The movable member can push the sliding ring 506 to the right and compress the first spring 501. Through the arrangement of the first spring 501 and the sliding seat 400, the sliding ring 506 and the sliding seat 400 cooperate with the first spring 501 to make the second clamping member drive the fabric to tighten, ensuring that the fabric is flat. In addition, during cutting, the elastic deformation of the first spring 501 can absorb part of the pressure of the cutting tool, offset the instantaneous thrust, avoid the fabric from being squeezed and deformed due to local high pressure, improve the cutting accuracy, and effectively prevent the raw material fabric from shifting.

[0029] The first clamping component includes a U-shaped frame 200 fixedly installed on the upper left side of the support platform 100. A support bar 204 is fixedly installed on the top left side of the support platform 100 and at the opening of the U-shaped frame 200. A pressure bar 203 is slidably connected to the opening of the U-shaped frame 200. A hand-tightening bolt 202 is threadedly connected to the top of the U-shaped frame 200. The end of the hand-tightening bolt 202 is threaded downward through the U-shaped frame 200 and rotatably connected to the top of the pressure bar 203. Through the setting of the first clamping component, the U-shaped frame 200 and the support bar 204 form a fabric placement space. The hand-tightening bolt 202 drives the pressure bar 203 to slide downward, forming a clamping force with the support bar 204. The pressure can be adjusted by turning the hand-tightening bolt 202 to adapt to fabrics of different thicknesses.

[0030] The U-shaped frame 200 has limiting holes 205 on both sides, which are set along the height. Each set of limiting holes 205 has a limiting post 201 slidably connected to its inner cavity. The opposite ends of the two sets of limiting posts 201 are respectively fixedly connected to the corresponding side ends of the pressure strip 203. Through the setting of the limiting holes 205 and the limiting posts 201, the limiting posts 201 slide in the limiting holes 205, restricting the movement trajectory of the pressure strip 203, preventing the pressure strip 203 from tilting or deviating, ensuring that the fabric is subjected to uniform force when clamped, avoiding fabric deformation or loosening due to uneven clamping, and improving clamping stability.

[0031] The second clamping component includes a square ring 401 fixedly mounted on the top of a sliding seat 400. A pressure plate 402 is slidably connected to the inner cavity of the square ring 401. Connecting rods 407 are fixedly connected to both ends of the pressure plate 402. The tops of the two sets of connecting rods 407 extend upwards through the square ring 401. A connecting strip 404 is fixedly connected to the tops of the two sets of connecting rods 407. A fixing bolt 406 is fixedly mounted on the top of the square ring 401. The end of the fixing bolt 406 extends upwards through the connecting strip 404. An adjusting nut 405 is threadedly connected to the end of the fixing bolt 406 located above the connecting strip 404. The bottom of the connecting bar 404 contacts the top of the connecting bar 404. The surfaces of the two sets of connecting rods 407 located above the connecting bar 404 are each fitted with a second spring 403. The two ends of the two sets of second springs 403 respectively contact the bottom of the corresponding side connecting bar 404 and the top of the square ring 401. With the setting of the second clamping member, the adjusting nut 405 presses down the connecting bar 404 to drive the pressure plate 402 to clamp the fabric. The clamping force can be flexibly controlled by rotating the adjusting nut 405. At the same time, the second spring 403 is fitted on the connecting rod 407. When the cutter presses down, the second spring 403 is compressed to generate a buffer force, reducing the direct rigid compression of the fabric by the pressure plate 402.

[0032] The movable component includes sliding grooves 105 formed on the lower inner walls of the front and rear sides of the square hole 101. Guide bars 505 are slidably connected to the inner cavities of the two sets of sliding grooves 105. The top of the guide bar 505 is fixedly connected to the bottom of the sliding ring 506, and a handle 504 is fixedly connected to the bottom of the guide bar 505. Anti-deviation components are provided on both sides of the guide bar 505 to fix the guide bar 505 and prevent it from deviating. Through the movable component, the sliding cooperation between the sliding grooves 105 and the guide bars 505 makes the sliding ring 506 move smoothly. The position of the sliding ring 506 can be easily adjusted by pushing the guide bars 505 with the handle 504, thereby adjusting the compression of the first spring 501 and increasing the elastic potential energy of the first spring 501. The higher the elastic potential energy of the first spring 501, the stronger its ability to absorb external forces. When the cutter is pressed down, a larger compression can absorb more cutting pressure through the elastic deformation of the spring, reducing the rigid compression of the raw material layout section.

[0033] The anti-deviation component includes a limiting groove 104 located at the bottom of the support platform 100 and at a corresponding position in each set of sliding grooves 105. The inner cavity of each set of limiting grooves 104 is connected to the inner cavity of the corresponding side sliding groove 105. Limiting bolts 502 are fixedly connected to the bottom of both ends of the guide strip 505. The ends of the two sets of limiting bolts 502 pass downward through the inner cavity of the corresponding side limiting groove 104. Limiting nuts 503 are threadedly connected to the ends of the two sets of limiting bolts 502. The top of the 3 contacts the bottom of the support platform 100. Through the setting of the anti-offset component, the limiting bolt 502 passes through the limiting groove 104 and connects with the limiting nut 503 to fix the guide bar 505 to the bottom of the support platform 100, preventing the guide bar 505 from shaking up and down or left and right, enhancing the structural stability of the moving part. At the same time, it ensures that the sliding ring 506 is accurately positioned during the adjustment process, avoiding inaccurate compression of the first spring 501 due to the offset of the guide bar 505, thereby ensuring the consistency of the fabric tension.

[0034] The support platform 100 has a strip groove 300 on the top right side, which runs along the square hole 101. A scale bar 303 is fixedly connected to the inner cavity of the strip groove 300. A square bar 302 is fixedly connected to the top of the sliding ring 506. A pointer 301 for pointing to the scale bar 303 is fixedly connected to one end of the square bar 302. Through the setting of the scale bar 303 and the pointer 301, the scale bar 303 and the pointer 301 form a visual adjustment mark. When the sliding ring 506 is pushed, the pointer 301 points to the scale bar 303, which can accurately locate the movement distance of the sliding ring 506, thereby quantifying the compression of the first spring 501. At the same time, the operator can intuitively control the tension of the fabric and the buffer force of the spring according to the scale value, which improves the accuracy and controllability of the operation and makes it easier to adapt to different cutting process requirements.

[0035] Working principle;

[0036] When in use, first place one end of the fabric in the first clamping member. The U-shaped frame 200 and the support bar 204 of the first clamping member form a fabric placement space. By turning the hand-tightening bolt 202, the pressure bar 203 slides downward in the U-shaped frame 200, which, together with the support bar 204, clamps one end of the fabric. At the same time, the limiting post 201 slides in the limiting hole 205 to ensure that the pressure bar 203 moves up and down smoothly, prevents tilting, and ensures that the fabric is firmly clamped.

[0037] Next, place the other end of the fabric in the second clamping member, and push the sliding seat 400 to the left. At the same time, compress the first spring 501 and move the second clamping frame to the left. Then, turn the adjusting nut 405. The adjusting nut 405 presses the connecting strip 404 downward, which moves the pressure plate 402 downward. The square ring 401 clamps the other end of the fabric. Then, release the handle. The first spring 501 pushes the second clamping frame to the right, thereby tightening the raw fabric and applying an outward pushing force to the other end of the raw fabric.

[0038] When the blade presses down, pressure is applied to the raw fabric and transmitted through the sliding seat 400 to the first spring 501, thereby offsetting part of the thrust of the first spring 501 and preventing excessive direct pressure from the pressure plate 402 on the fabric. This buffering mechanism can reduce local compression deformation of the raw fabric caused by instantaneous high pressure.

[0039] At the same time, loosen the limiting nut 503 and push the handle to the right to increase the compression of the spring, and tighten the limiting nut 503 to prevent the handle 504 from resetting, thereby increasing the elastic potential energy of the first spring 501. The higher the elastic potential energy of the first spring 501, the stronger its ability to absorb external forces. When the cutter is pressed down, a greater amount of compression can absorb more cutting pressure through the elastic deformation of the spring, reducing the rigid compression of the raw material layout section.

[0040] 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 these 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.
