Description

Technical Field

[0001] This invention relates to the field of fabric clamping technology, and in particular to a clamping device for irregularly shaped fabrics and its method of use. Background Technology

[0002] Fabrics typically require clamping before sewing, but this is particularly challenging with irregularly shaped products. For irregularly shaped fabrics such as pyramids, frustums, or truncated cones with curved surfaces, there are currently no clamping devices available on the market. These fabrics are mostly sewn manually, but manual sewing of fabrics of varying thicknesses and densities demands a high level of skill from the operator, involves long continuous sewing times, high workload, and fatigue, leading to increased defects, poor consistency, and ultimately, products that fail to meet quality requirements.

[0003] Therefore, for sewing such irregularly shaped fabrics, a new type of fabric clamping device is needed to reduce the difficulty of sewing irregularly shaped fabrics and improve the sewing qualification rate. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

The vertical moving module is fixed on the slider at the top of the horizontal moving module, and the bottom four corners of the horizontal moving module are equipped with casters via a base.

[0009] In a preferred embodiment of the irregular fabric clamping device of the present invention, the bottom of the support clamping module slides on the moving guide rail, and several sets of support clamping modules and tension adjustment modules are arranged along the front end to the rear end of the moving guide rail, and the height of each set of support clamping modules is different.

[0010] As a preferred embodiment of the irregular fabric clamping device of the present invention, the supporting clamping module includes a rotating screw, a connecting slider, a supporting beam and a supporting member. The two ends of the rotating screw rotate symmetrically on the side wall of the connecting slider. The bottom of the connecting slider is detachably slidable on the upper end of the moving guide rail. The bottom of the supporting beam is hinged to the top of the connecting slider. The side of the supporting beam that is close to each other is connected to the rotating screw through the supporting member.

[0011] As a preferred embodiment of the irregular fabric clamping device of the present invention, the support member includes a support arm and a drive slider. One end of the support arm is hinged to the middle side wall of the support beam, and the other end is hinged to the top of the drive slider, while the drive slider is rotatably sleeved on the rotating lead screw.

[0012] As a preferred embodiment of the irregular fabric clamping device of the present invention, the rotating screw has symmetrically arranged threaded grooves in opposite directions on its body, each of which cooperates with the driving slider to rotate, and a rotating handle is provided at either end of the rotating screw through the side wall of the connecting slider.

[0013] In a preferred embodiment of the irregular fabric clamping device of the present invention, the tension adjustment module includes a fabric belt, a ratchet, and an adjustment box.

The ratchet is rotatably connected to the adjustment box via a rotating shaft, and one end of the ratchet passes through the side wall of the adjustment box and is connected to a dial. The adjustment box is symmetrically fixed on the side walls of the support beam that are far apart from each other. A pin is rotatably disposed in the side wall of the adjustment box. The pin is radially perpendicular to the rotating shaft of the ratchet, and its end movably abuts against the side wall of the rotating shaft of the ratchet.

[0014] As a preferred embodiment of the irregular fabric clamping device of the present invention, an independent binding cloth strap is also provided in the tension adjustment module at the front end, and the two ends of the binding cloth strap are each connected to the adjustment box through the ratchet.

[0015] As a preferred embodiment of the irregular fabric clamping device of the present invention, a limit post is symmetrically arranged on the side wall of the support beam in the rear support clamping module, and a baffle is movably arranged.

[0020] Adjust each of the ratchet wheels to adjust the tension of the belt, keep the binding belt loose, and move the baffle to unfold it;

[0021] Place the irregular fabric to be sewn on each set of the fabric strips, so that its tail end contacts the baffle, keeping the sewing side facing up, place the binding fabric strip on the upper surface of the irregular fabric, and adjust the ratchet to tighten it.

[0022] When it is necessary to adjust the sewing surface, first loosen the binding tape, then rotate the irregular fabric so that the target sewing surface faces upward. According to the sewing requirements, adjust the spacing and opening angle of each set of support beams and the tension of the tape and binding tape to keep the sewing surface stable.

[0023] Once sewing is complete, loosen the binding straps and remove the irregularly shaped fabric.

[0024] Repeat the above steps to sew the next irregular fabric, or reverse the above steps to restore the device to its initial state.

[0025] The beneficial effects of this invention are:

[0026] In this invention, the support and clamping modules that slide on the guide rail can adapt to irregularly shaped fabrics of different lengths, while the support beam with adjustable angle can adapt to irregularly shaped fabrics of different widths. The fabric strip will not damage the fabric and can adapt to the curved surface of the irregularly shaped fabric, which is conducive to the placement and clamping of the irregularly shaped fabric, greatly reducing the difficulty of sewing irregularly shaped fabrics and improving the sewing efficiency.

[0039] Example 1

[0040] Reference Figure 1 The first embodiment of the present invention provides a shaped fabric clamping device, which includes a moving adjustment unit 100 and a clamping adjustment unit 200. The moving adjustment unit 100 includes a moving module 101 and a moving guide rail 102, and the moving guide rail 102 is fixed on the top slider of the moving module 101. The clamping adjustment unit 200 is detachably slidable on the moving guide rail 102, and includes a support clamping module 201 and a tension adjustment module 202, which are symmetrically arranged on the outside of the support clamping module 201.

[0041] This device is used in conjunction with a fabric sewing equipment. The moving module 101 in the moving adjustment unit 100 is used to move the clamped irregular fabric. During sewing, it moves laterally or longitudinally in accordance with the sewing path. The moving guide rail 102 is installed on the moving module 101 for detachable installation of the clamping adjustment unit 200. The clamping adjustment unit 200 is the part for placing and clamping the irregular fabric. The supporting clamping module 201 adjusts its own state to form the main frame for placing the irregular fabric. The tension adjustment module 202 is set on the supporting clamping module 201. Through cooperation with the supporting clamping module 201, it forms a shape that matches the irregular fabric, clamps it, and limits its position, thereby cooperating with the fabric sewing equipment to complete the sewing work.

[0042] Example 2

[0043] Reference Figure 1 and 2This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the moving module 101 includes a horizontal moving module 101a and a vertical moving module 101b. The horizontal moving module 101a and the vertical moving module 101b have the same overall structure. The vertical moving module 101b is fixed to the slider on the top of the horizontal moving module 101a, and the four bottom corners of the horizontal moving module 101a are equipped with casters 101c via bases.

[0044] Compared to Embodiment 1, the moving module 101 further comprises two sets of moving modules: a horizontal moving module 101b and a vertical moving module 101b. The vertical moving module 101b moves in the opposite direction to the horizontal moving module 101a. These two modules are used to achieve horizontal and vertical movement, respectively, enabling the clamping adjustment unit 200 to move to any position within the plane, corresponding to the sewing work at any point on the irregular fabric sewing surface. It should be noted that the horizontal moving module 101a and the vertical moving module 101b have the same structure and can be constructed using commercially available finished products, as long as they can achieve movement to any point within the plane. A caster wheel 101c is installed at the bottom of the horizontal moving module 101a to facilitate moving the device to the desired position during use.

[0045] The remaining structure is the same as that in Example 1.

[0046] Example 3

[0047] Reference Figures 2-5 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the bottom of the support clamping module 201 slides on the moving guide rail 102. Several sets of support clamping modules 201 and tension adjustment modules 202 are arranged along the front end to the rear end of the moving guide rail 102, and the height of each set of support clamping modules 201 is different.

[0048] The support clamping module 201 includes a rotating lead screw 201a, a connecting slider 201b, a support beam 201c, and a support member 201d. The two ends of the rotating lead screw 201a rotate symmetrically on the side wall of the connecting slider 201b. The bottom of the connecting slider 201b is detachably slidable on the upper end of the moving guide rail 102. The bottom of the support beam 201c is hinged to the top of the connecting slider 201b. The side of the support beams 201c that are close to each other is connected to the rotating lead screw 201a through the support member 201d.

[0049] The support 201d includes a support arm 201d-1 and a drive slider 201d-2. One end of the support arm 201d-1 is hinged to the middle side wall of the support beam 201c, and the other end is hinged to the top of the drive slider 201d-2. The drive slider 201d-2 is rotatably sleeved on the rotating lead screw 201a.

[0050] The rotating screw 201a has symmetrically arranged threaded grooves in opposite directions on its body. Each of these bidirectional threaded grooves is engaged with the drive slider 201d-2 to rotate. A rotating handle 201a-1 is provided at either end of the rotating screw 201a, which passes through the side wall of the slider 201b.

[0051] Compared to embodiment 2, furthermore, the support clamping module 201 is provided with multiple sets, such as... Figure 3 In this embodiment, three sets are used as an example, and they can be detachably slidable on the moving guide rail 102. The purpose is to add any set of support clamping modules 201 on the moving guide rail 102 for different lengths of irregular fabrics. Multiple sets of support clamping modules 201 also have better clamping stability. The support clamping modules 201 of different heights are designed to adapt to the shape of different positions of irregular fabrics by adjusting the height and degree of opening and closing.

[0052] Specifically, in combination Figure 3 and 4 The rotating lead screw 201a has identical structures symmetrically arranged on both sides. The bottom of the connecting slider 201b has a groove that slides in conjunction with the moving guide rail 102. The support beam 201c is U-shaped, meaning it has a certain width. The U-shaped opening is hinged to the top of the connecting slider 201b. The support beams 201c on both sides of the rotating lead screw 201a form different opening and closing angles through the hinged ends, which are used to match irregularly shaped fabrics of different widths. In order to maintain the mirror-symmetrical movement of the support beams 201c, the support member 201d is used in conjunction with... The two-way thread on the rotating lead screw 201a is used to achieve this. The drive sliders 201d-2 located on both sides of the rotating lead screw 201a are matched with the corresponding thread grooves. When the rotating lead screw 201a rotates, the two drive sliders 201d-2 always maintain opposite symmetrical movement. The support arm 201d-1 has the function of increasing the strength of the support beam 201c and pushing the support beam 201c to deflect. It should be noted that the movement of the drive slider 201d-2 on one side can also be manually rotated to cope with more irregular and irregular shaped fabrics.

[0053] The remaining structure is the same as that in Example 2.

[0054] Example 4

[0055] Reference Figure 3 and 5~7 is the fourth embodiment of the present invention. This embodiment differs from the third embodiment in that: the tension adjustment module 202 includes a cloth belt 202a, a ratchet 202b, and an adjustment box 202c. The two ends of the cloth belt 202a are rotatably stored on the ratchet 202b, and the middle part is placed on the top of the support beam 201c. The ratchet 202b is rotatably connected to the adjustment box 202c through a rotating shaft, and one end of it passes through the side wall of the adjustment box 202c and is connected to the dial. The adjustment box 202c is symmetrically fixed on the side walls of the support beam 201c that are far apart from each other.

[0056] A pin 202c-1 is rotatably disposed in the side wall of the adjusting box 202c. The pin 202c-1 is radially perpendicular to the rotating shaft of the ratchet 202b, and its end is movably abutting against the side wall of the rotating shaft of the ratchet 202b.

[0057] Located in the front tension adjustment module 202, there is also an independent restraint cloth 202d. Both ends of the restraint cloth 202d are connected to the adjustment box 202c through ratchet 202b.

[0058] Compared to embodiment 3, further, in the tension adjustment module 202, the fabric belt 202a is used for direct contact with the irregular fabric. The fabric belt 202a is soft and will not damage the irregular fabric it contacts. Its tension is easily adjustable, allowing it to easily adapt to the contours of the irregular fabric. It can be made of low-elasticity, high-strength nylon material. At least one fabric belt 202a is placed on each support beam 201c. The ratchet 202b is used to store the fabric belt 202a and can easily adjust the overall tension of the fabric belt 202a. The ratchet 202b is rotatably mounted in the adjustment box 202c via a central rotating shaft. Its rotation is achieved through... The dial extending outside the box achieves this. When the belt 202a is taut, the ratchet 202b needs to be stationary. This is achieved by pin 202c-1, which is rotatably connected to the side wall of the adjustment box 202c from the outside. The pivot of the ratchet 202b is located at the top of the insertion hole of pin 202c-1, meaning that pin 202c-1 can abut against the pivot of the ratchet 202b, thereby preventing the ratchet 202b from rotating. The adjustment box 202c is symmetrically installed on the side wall of each set of support beams 201c on the side away from each other, for the purpose of installing and protecting the ratchet 202b.

[0059] Furthermore, two sets of ratchet wheels 202b are installed in the adjustment box 202c located at the front end of the longitudinal movement module 101b. These ratchet wheels are used to store and adjust the binding straps 202d. The binding straps 202d are used to place on the upper surface of the irregular fabric and, together with each strap 202a, clamp the placed irregular fabric.

[0060] The remaining structure is the same as that in Example 3.

[0061] Example 5

[0062] Reference Figure 5 This is the fifth embodiment of the present invention. The difference between this embodiment and the fourth embodiment is that: limit posts 201c-1 and movable baffles 201c-2 are symmetrically arranged on the side wall of the support beam 201c in the rear support clamping module 201.

[0063] The baffle 201c-2 includes a first baffle 201c-21 and a second baffle 201c-22. One end of the first baffle 201c-21 and the second baffle 201c-22 are rotatably connected, and a limiting groove 201c-23 is formed on the side wall of the other end. The limiting post 201c-1 passes through and slides in the limiting groove 201c-23.

[0064] Compared to embodiment 4, furthermore, to prevent the placed irregular fabric from moving within the support clamping module 201, it is necessary to limit the placement of the irregular fabric at the tail end of the longitudinal moving module 101b; preferably, this is achieved by symmetrically arranged baffles 201c-2. Specifically, the baffles 201c-2 can be housed on the side wall of the support beam 201c. As shown in the attached figure, on the outer side wall of the support beam 201c at the tail end of the longitudinal moving module 101b, limit posts 201c-1 are symmetrically distributed vertically to limit the first stop bar 201. At positions c-21 and the second stop 201c-22, both stop rods have elongated straight grooves on their side walls. A limiting post 201c-1 passes through the straight groove. One end of the two stop rods is rotatably connected, while the other end is movable. The distance between the two limiting posts 201c-1 is greater than the maximum distance between the two straight grooves, but less than the maximum distance between the two stop rods. This makes it easy to move the two stop rods through the limiting post 201c-1 to form a triangular baffle 201c-2. When not in use, the baffle can be retracted onto the side wall of the support beam 201c for convenient use.

[0065] The remaining structure is the same as that in Example 4.

[0066] Example 6

[0067] Reference Figures 1-7 The sixth embodiment of the present invention provides a method for using the irregular fabric clamping device: this method uses the above-mentioned irregular fabric clamping device and further includes the following steps:

[0068] Adjust the spacing of each set of support clamping modules 201 and the opening angle of each set of support beams 201c according to the size and length of the irregular fabric to be sewn.

[0069] Adjust each ratchet 202b, adjust the tension of the cloth belt 202a, keep the binding cloth belt 202d loose, and move the baffle 201c-2 to unfold it;

[0070] Place the irregular fabric to be sewn on each set of fabric tapes 202a, so that its tail end contacts the baffle 201c-2, keeping the sewing side facing up, place the binding fabric tape 202d on the upper surface of the irregular fabric, and adjust the ratchet 202b to make it taut.

[0071] When it is necessary to adjust the sewing surface, first loosen the binding tape 202d, then rotate the irregular fabric so that the target sewing surface faces upward. According to the sewing requirements, adjust the spacing and opening angle of each set of support beams 201c and the tension of tape 202a and binding tape 202d to maintain the stability of the sewing surface.

[0072] Once sewing is complete, loosen the binding tape 202d and remove the irregular fabric.

[0073] Repeat the above steps to sew the next irregular fabric, or reverse the above steps to restore the device to its initial state.

[0074] Before use, based on the size, length, and shape of the irregular fabric to be sewn, install and allocate the appropriate number, spacing, and height combination of support clamping modules 201. Then, by controlling the rotation of the lead screw 201a, the drive slider 201d-2 is moved on the lead screw, which in turn drives the corresponding set of support beams 201c to open at the corresponding angle through the support arm 201d-1. Then, by rotating each ratchet 202b, the tightness of each set of corresponding fabric tapes 202a is adjusted. At the same time, by rotating the ratchet 202b corresponding to the binding fabric tape 202d, the binding fabric tape 202d is kept in a relaxed state, and the baffle 201c-2 is unfolded, completing all the preparation work. Place the irregularly shaped fabric to be sewn on each set of fabric tapes 202a. Once it is stable under its own weight, ensure the tail end of the fabric contacts the baffle 201c-2 and as many fabric tapes 202a as possible to maintain stability. Keep the sewing surface facing upwards and adjust the tension of the fabric tapes 202a to maximize the sewing surface's fit to the sewing equipment's requirements. After positioning, place the restraining fabric tape 202d on the upper surface of the irregularly shaped fabric and tighten it using the corresponding ratchet 202b. This ensures stable clamping of the irregularly shaped fabric. The sewing equipment performs the sewing operation. When changing the sewing surface, first loosen the restraining fabric tape 202d, then rotate the irregularly shaped fabric to achieve the desired sewing surface. Adjust each set of fabric tapes 202a to maintain the fabric's stability, and then tighten the restraining fabric tape 202d to re-clamp the irregularly shaped fabric.

[0075] Once all sewn surfaces are complete, release the binding tape 202d and remove the finished shaped fabric. Repeat the above steps to sew the next shaped fabric, or reverse the steps to return the clamping device to its initial state.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
