Description

A wide-width positioning fixture adaptable to various specifications of flame-retardant polyester-viscose fabric Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically a wide positioning tooling adapted to flame-retardant polyester-viscose fabrics of various specifications. Background Technology

[0002] Flame-retardant polyester-viscose blend is a functional fabric made from a blend of polyester and viscose, treated with flame retardants. It is widely used in specialty clothing, vehicle interiors, and public space decoration. Because of its smooth surface and moderate flexibility, this type of fabric is prone to slippage or wrinkling if not kept taut during processing, affecting the accuracy of precision operations such as spraying or laser coating.

[0003] Patent CN215164049U discloses a positioning fixture for processing flame-retardant polyester fabric. Addressing the problem that existing technologies cannot meet the positioning requirements of fabrics of different lengths and widths, the patent proposes the following solution: A processing table has two slots at its top. Each slot has a first threaded rod rotatably connected to its interior. These first threaded rods are driven by a transmission mechanism mounted on one side of the processing table. Each of the first threaded rods has two threaded sleeves threaded to its exterior. A support plate is fixedly connected to the top of each of the four threaded sleeves. This patent can meet the need for fixing flame-retardant polyester fabrics of different lengths and widths, preventing movement of the fabric during cutting, improving cutting accuracy, and eliminating the need for manual measurement during the cutting process, thus avoiding errors caused by manual measurement.

[0004] As described above, in the processing of functional fabrics such as flame-retardant polyester-viscose fabrics, including processes like spraying, hot pressing, laser cutting, positioning punching, and inspection, it is often necessary to keep the fabric flat and taut. Existing technologies typically employ static platform laying or manual tensioning of the fabric before fixing it to fixtures, which is cumbersome, time-consuming, and prone to inconsistent fabric tension control, easily causing processing deviations, wrinkles, or curling edges, affecting processing accuracy and quality. Furthermore, the fabric changeover process is complex; if frequent changes to different fabric specifications are required or small-batch, diversified production is needed, existing platforms are inefficient.

[0005] Especially for flame-retardant polyester-viscose fabrics, which have a certain rigidity and strong sliding properties, slippage and insufficient tension are more likely to occur during clamping and tensioning. Traditional fixing methods cannot meet the dual requirements of quick loading and unloading and tension retention. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a wide-width positioning fixture that is compatible with flame-retardant polyester-viscose fabrics of various specifications, solving the problem that traditional fixing methods cannot simultaneously meet the dual requirements of rapid loading and unloading and tension retention.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wide-width positioning fixture adaptable to various specifications of flame-retardant polyester-viscose fabric, comprising:

[0008] The supporting base frame has a left circular groove on its top, a fixing groove on one side of its surface, and a stable base at its bottom.

[0009] A positioning and tensioning assembly, one side of which is fixedly connected to one side of the supporting base frame, is used to tension and position the flame-retardant polyester-viscose fabric.

[0010] A clamping assembly, one side of which is movably connected to the inner wall of a positioning and tensioning assembly, is used to stably clamp flame-retardant polyester-viscose fabrics of various specifications.

[0011] Preferably, the positioning and tensioning assembly includes a guide rod fixedly connected to the top of the supporting base frame, a movable sleeve movably sleeved on the surface of the guide rod, an adjusting groove block fixedly connected to the bottom of the movable sleeve, a right circular groove opened on the top of the adjusting groove block, an adjusting slider movably connected to the inner wall of the adjusting groove block, and a positioning slider movably connected to the inner wall of the fixed groove.

[0012] Preferably, one side of both the positioning slider and the adjusting slider is fixedly connected to a surrounding frame, and the top of each surrounding frame is provided with a mounting groove, the inner wall of which is movably connected to a pin plate.

[0013] Preferably, a horizontal plate is fixedly connected to the bottom of the adjusting groove block, and a screw rod is rotatably connected to the surface of the horizontal plate. One end of the screw rod passes through the supporting bottom frame and extends to the outside of the supporting bottom frame.

[0014] Preferably, the clamping assembly includes an outer frame movably connected to the positioning and tensioning assembly, and a spring is fixedly connected to one side of the inner wall of the outer frame.

[0015] Preferably, one end of the spring is fixedly connected to a clamping plate, and one side of the clamping plate is fixedly connected to a handle.

[0016] This invention provides a wide-width positioning fixture adaptable to various specifications of flame-retardant polyester-viscose fabrics. Compared with the prior art, it has the following advantages:

[0017] 1. This wide-width positioning fixture, compatible with various specifications of flame-retardant polyester-viscose fabrics, utilizes a clamping assembly to pre-clamp the fabric within a detachable outer frame. The entire frame can be quickly docked with or detached from the fixture. Fabric changes no longer require repeated tensioning and manual positioning, significantly reducing changeover time. Users simply assemble the clamping frame with the new fabric, insert it into the fixture with a single click, and can immediately begin processing. This method is particularly suitable for processing multiple batches and specifications of fabrics, greatly improving production cycle time and automation. Simultaneously, standardized fixtures control fabric tension and positional accuracy, effectively reducing waste caused by human error.

[0018] 2. This wide-width positioning fixture, adaptable to various specifications of flame-retardant polyester-viscose fabrics, features a positioning and tensioning component. Another core advantage of this equipment is its manually adjustable tensioning mechanism, which continuously applies constant tension to the other end of the fabric, achieving automatic tensioning and preventing wrinkles and slippage caused by slack during processing. Regardless of fabric size or thickness, the fabric surface remains flat. It is particularly suitable for flame-retardant polyester-viscose fabrics, which have a certain thickness and are difficult to adhere to platforms, improving processing quality, avoiding rework, and meeting the high precision and consistency requirements of modern flexible manufacturing.

[0025] 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.

[0026] Please refer to Figures 1-5. This utility model provides two technical solutions:

[0027] Example 1: A wide-width positioning fixture adapted to various specifications of flame-retardant polyester-viscose fabric, comprising:

[0028] The supporting base frame 1 has a lifting ring on its top and multiple sets of mounting holes on its inner wall bottom for connection with subsequent equipment. The top of the supporting base frame 1 has a left circular groove 2, and one side of the surface of the supporting base frame 1 has a fixing groove 3. The cross-section of the fixing groove 3 is dovetail-shaped. The bottom of the supporting base frame 1 has a stable base 4.

[0029] Positioning and tensioning component 5, one side of positioning and tensioning component 5 is fixedly connected to one side of the supporting bottom frame 1, and positioning and tensioning component 5 is used to tension and position the flame-retardant polyester-viscose fabric;

[0030] The clamping component 6 is movably connected to the inner wall of the positioning and tensioning component 5 on one side. The clamping component 6 is used to stably clamp flame-retardant polyester-viscose fabrics of various specifications. Utilizing the clamping component 6, the device pre-clamps the fabric within the detachable outer frame 61. The entire frame can be quickly docked with or detached from the tooling. Fabric changes do not require repeated tensioning and manual positioning each time, greatly saving changeover time. Users simply assemble the clamping frame with the new fabric, insert it into the tooling with one click, and can immediately begin processing. This method is particularly suitable for processing multiple batches and specifications of fabrics, greatly improving production cycle time and automation. Simultaneously, by controlling fabric tension and positional accuracy through standardized clamps, the scrap rate caused by human error is effectively reduced.

[0031] Example 2 differs from Example 1 primarily in that it includes a wide-width positioning fixture adaptable to various specifications of flame-retardant polyester-viscose fabric. The positioning and tensioning assembly 5 includes a guide rod 51 fixedly connected to the top of the supporting base frame 1. A movable sleeve 52 is movably fitted onto the surface of the guide rod 51. An adjusting groove block 53 is fixedly connected to the bottom of the movable sleeve 52. The adjusting groove block 53 has a built-in dovetail groove and a right circular groove 54 at its top. An adjusting slider 55 is movably connected to the inner wall of the adjusting groove block 53. The adjusting slider 55 has a dovetail-shaped cross-section. A positioning slider 56 is movably connected to the inner wall of the fixed groove 3. A surrounding frame 57 is fixedly connected to one side of both the positioning slider 56 and the adjusting slider 55. A mounting circular groove 58 is opened at the top of each surrounding frame 57. A pin plate 59 is movably connected to the inner wall of the mounting circular groove 58. Two cylinders are provided at the bottom of the pin plate 59, which can be adapted to the mounting circular groove 58, the left circular groove 2, and the right circular groove 54. The grooves are of the same specifications. A horizontal plate 510 is fixedly connected to the bottom of the adjusting groove block 53. A screw rod 511 is rotatably connected to the surface of the horizontal plate 510. One end of the screw rod 511 passes through the supporting base frame 1 and extends to the outside of the supporting base frame 1. A handle is provided at one end of the screw rod 511. The clamping assembly 6 includes an outer frame 61 that is movably connected to the positioning and tensioning assembly 5. A spring 62 is fixedly connected to one side of the inner wall of the outer frame 61. A damper is provided on the inner wall of the spring 62. A clamping plate 63 is fixedly connected to one end of the spring 62. A silicone pad is provided on the side of the clamping plate 63 that contacts the fabric. A handle 64 is fixedly connected to one side of the clamping plate 63. An anti-slip pad is provided on the surface of the handle 64. With the setting of the positioning and tensioning assembly 5, another core advantage of this equipment is its manually adjustable tensioning mechanism, which can continuously apply a constant tension to the other end of the fabric to achieve automatic tensioning and prevent wrinkling, slippage, and other phenomena caused by loosening during processing. Regardless of the size or thickness of the fabric, the fabric surface always remains flat. It is especially suitable for flame-retardant polyester-viscose fabrics, which have a certain thickness and are not easy to adhere to the platform, thus improving the processing quality, avoiding repeated rework, and meeting the requirements of modern flexible manufacturing for high precision and high consistency.

[0032] This equipment effectively secures and maintains constant tension on flame-retardant polyester-viscose fabric through pre-clamping and tooling tension, making it particularly suitable for large-format unfolding and tension-sensitive processing. For example, the fabric must be completely flat before laser cutting, otherwise the cutting accuracy will be affected; this device keeps it under stable tension at all times, greatly improving processing accuracy and efficiency, and reducing the defect rate caused by fabric movement. Furthermore, this type of fabric is commonly used in batch processing scenarios, and the device's quick changeover capability enhances the overall production line adaptability.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, select two different clamping components 6, pull the handle 64 to move the clamping plate 63 to both sides, and pass the flame-retardant polyester-adhesive fabric through the two different clamping components 6 on the left and right sides respectively. At the same time, the spring 62 in the outer frame 61 is compressed. After the flame-retardant polyester-adhesive fabric passes through the clamping plate 63, release the handle 64. The spring 62 extends and pushes the clamping plate 63 to clamp and fix the flame-retardant polyester-adhesive fabric. Place the outer frame 61 in the predetermined position on the tooling surface. First, fix the clamping component 6 on the left side, slide the positioning slider 56 on the inner wall of the sliding fixing groove 3, and move the surrounding frame 57. Hold the clamping component 6 and place it stably. Push the positioning slider 56 along the fixing groove 3 to restore the position of the surrounding frame 57. The surrounding frames 57 on both sides of the supporting bottom frame 1 will fit the clamping component 6. When the surrounding frame 57 moves to its original position... Then, insert the pin plate 59 into the left circular groove 2 and the mounting circular groove 58, effectively fixing the surrounding frame 57 and the left clamping component 6. Similarly, after placing the right clamping component 6 stably, move the adjusting slider 55 along the adjusting groove block 53 to fit the surrounding frame 57 onto the surface of the right clamping component 6. Then, align the right circular groove 54 and the mounting circular groove 58 and insert the pin plate 59, fixing the right surrounding frame 57 and thus fixing the right clamping component 6. To tighten the fabric in the clamping component 6, rotate the screw rod 511, causing the horizontal plate 510 to move. The moving sleeve 52 slides along the guide rod 51. When the flame-retardant polyester woven fabric is straightened and tightened, stop rotating the screw rod 511, allowing the operator to perform subsequent operations on the flame-retardant polyester woven fabric. When the tooling is finished, restore it to its original state.
