Description

Technical Field

[0001] This application relates to the field of textile processing technology, and in particular to a fabric fastening device. Background Technology

[0002] Tufting is a widely used textile processing technique. Specifically, it involves inserting yarn into a base fabric and then cutting it to create a plush effect, resulting in tufted products. In the preparation stage of tufting, the fabric needs to be secured. Current technology typically uses nails to fasten the fabric to a frame around its perimeter. However, this method can easily lead to users being scratched by the nails during operation, compromising safety. Summary of the Invention

[0003] This application provides a fabric fixing device, which aims to fix taut fabric and improve operational safety when fixing fabric.

[0004] This application provides a fabric fastening device, including:

[0005] Support frame;

[0006] Two first clamping mechanisms are spaced apart along a first direction, and the opposite ends of the first clamping mechanisms are rotatably connected to the support frame.

[0007] The first clamping mechanism includes a first clamping member and a second clamping member for clamping the fabric. The second clamping member can move relatively close to or away from the first clamping member. When the fabric is located between the first clamping member and the second clamping member, the first clamping member and the second clamping member can rotate so that the first clamping member and the second clamping member drive the fabric to roll around. The second clamping member can move toward the first clamping member and clamp the fabric with the first clamping member under the drive of the fabric.

[0008] This application provides a fabric fixing device that uses two first clamping mechanisms to clamp two different positions of the fabric. Specifically, the fabric is placed between the first and second clamping members, and then the first and second clamping members are controlled to rotate relative to a support frame. This allows the first and second clamping members to wind the fabric, and the second clamping member moves towards the first clamping member, clamping the fabric together with the first clamping member, thus fixing the fabric. Furthermore, the two first clamping mechanisms, by winding the fabric at two different positions, also tighten the portion of the fabric between these two positions that is to be threaded, facilitating subsequent tufting, embroidery, or sewing on this portion. This fabric fixing device eliminates the need for sharp parts; by controlling the rotation of the first and second clamping members together, it achieves both fabric fixing and tightening, improving operational safety during fabric fixing.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0033] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Please refer to Figures 1 to 4 This application provides a fabric 100 fixing device, which includes a support frame 1 and two first clamping mechanisms 2. The two first clamping mechanisms 2 are spaced apart along a first direction, and their opposite ends are rotatably connected to the support frame 1. Each first clamping mechanism 2 includes a first clamping member 21 and a second clamping member 22 for clamping the fabric 100. The second clamping member 22 can move closer to or further away from the first clamping member 21. When the fabric 100 is located between the first clamping member 21 and the second clamping member 22, the first clamping member 21 and the second clamping member 22 can rotate, causing the first clamping member 21 and the second clamping member 22 to drive the fabric 100 to roll around. The second clamping member 22 can move towards the first clamping member 21 and, driven by the fabric 100, clamp the fabric 100 with the first clamping member 21.

[0036] For example, the first direction can be as follows: Figure 1 The Z0-Z1 direction is shown.

[0037] Understandably, the two first clamping mechanisms 2 can clamp two positions of the fabric 100 respectively. Specifically, by placing the fabric 100 between the first clamping member 21 and the second clamping member 22, and then controlling the first clamping member 21 and the second clamping member 22 to rotate relative to the support frame 1, the first clamping member 21 and the second clamping member 22 can drive the fabric 100 to be wound. The second clamping member 22 can move towards the first clamping member 21 and, driven by the fabric 100, clamp the fabric 100 with the first clamping member 21, thereby fixing the fabric 100. In addition, the two first clamping mechanisms 2 can also tighten the part of the fabric 100 between these two positions that is to be threaded, which is convenient for subsequent tufting, embroidery or sewing on the part to be threaded. The fabric 100 fixing device of this application embodiment does not require sharp parts. By controlling the first clamping member 21 and the second clamping member 22 to rotate together, the fabric 100 is fixed and tightened, which helps to improve the operational safety when fixing the fabric 100.

[0038] In some embodiments, when the fabric 100 is located between the first clamp 21 and the second clamp 22, and the first clamp 21 and the second clamp 22 rotate to cause the fabric 100 to wrap around the fabric 100 so that the fabric 100 wraps around at least part of the second clamp 22, the fabric 100 can exert force on the second clamp 22 so that the second clamp 22 moves closer to the first clamp 21. Understandably, the rotation of the first clamping member 21 and the second clamping member 22 causes the fabric 100 to be wound. The fabric 100 can be wound along the rotation direction of the first clamping member 21 and the second clamping member 22. During the process of the first clamping member 21 and the second clamping member 22 rotating and causing the fabric 100 to be wound, the fabric 100 can gradually wrap around the outer periphery of the second clamping member 22. When the fabric 100 wraps at least part of the second clamping member 22, as the first clamping member 21 and the second clamping member 22 continue to rotate, the fabric 100 can exert force on the second clamping member 22, so that the second clamping member 22 moves closer to the first clamping member 21 during rotation. The first clamping member 21 and the second clamping member 22 can clamp the fabric 100 and fix the fabric 100.

[0039] In some embodiments, when the fabric 100 is located between the first clamping member 21 and the second clamping member 22, the rotation of the first clamping member 21 and the second clamping member 22 causes the fabric 100 to be wound, and the second clamping member 22 can move closer to the first clamping member 21 under the action of gravity. When the fabric 100 is located between the first clamping member 21 and the second clamping member 22, and the rotation of the first clamping member 21 and the second clamping member 22 causes the fabric 100 to be wound, such that the fabric 100 wraps at least part of the second clamping member 22, the fabric 100 can exert force on the second clamping member 22, so that the second clamping member 22 moves closer to the first clamping member 21. Understandably, during the rotation of the first clamping member 21 and the second clamping member 22, when the second clamping member 22 is located above the first clamping member 21 in the direction of gravity, the second clamping member 22 can move closer to the first clamping member 21 under the action of gravity. Then, the fabric 100 continues to wrap around the outer periphery of the second clamping member 22, so that the fabric 100 can apply force to the second clamping member 22 to make the second clamping member 22 move further closer to the first clamping member 21, so that the first clamping member 21 and the second clamping member 22 stably clamp the fabric 100.

[0040] In some embodiments, a guide structure (not shown) is provided on the support frame 1. After the fabric 100 is placed between the first clamping member 21 and the second clamping member 22, during the synchronous rotation of the first clamping member 21 and the second clamping member 22, the first clamping member 21 and the second clamping member 22 drive the fabric 100 to roll around. Under the guidance of the guide structure, the second clamping member 22 can approach the first clamping member 21, and the fabric 100 is wrapped around the outer periphery of the second clamping member 22, so that the second clamping member 22 stably clamps the fabric 100 under the guidance of the guide structure and the force applied by the fabric 100.

[0041] For example, the guide structure is located on the outer periphery of the second clamping member 22, the second clamping member 22 can abut against the guide surface of the guide structure, and during the rotation of the second clamping member 22, the second clamping member 22 can slide along the guide surface of the guide structure, so that the second clamping member 22 gradually approaches the first clamping member 21 under the guidance of the guide structure.

[0042] In some embodiments, the second clamping member 22 is capable of moving away from the first clamping member 21 under the force applied by the fabric 100, and / or, the second clamping member 22 is capable of moving away from the first clamping member 21 under the action of gravity, and / or, the second clamping member 22 is capable of moving away from the first clamping member 21 under the action of an external force other than the force applied by the fabric 100. Understandably, if the rotation direction when the first clamping member 21 and the second clamping member 22 clamps and fixes the fabric 100 is taken as positive, then when it is necessary to remove the fabric 100 or adjust the fabric 100, the first clamping member 21 and the second clamping member 22 can rotate in opposite directions, and the fabric 100 is gradually unrolled. During this process, the second clamping member 22 can move away from the first clamping member 21 under the action of the force applied by the fabric 100, and / or under its own gravity, and / or under the action of an external force other than the force applied by the fabric 100. The first clamping member 21 and the second clamping member 22 release the fabric 100, so that the fabric 100 can be removed or moved.

[0043] In some embodiments, the first clamping member 21 and the second clamping member 22 are rotated by an angle α so that the first clamping member 21 and the second clamping member 22 clamp the fabric 100, where 240°≤α≤360°.

[0044] Furthermore, 270°≤a≤360°. It is understandable that when the rotation angles of the first clamping member 21 and the second clamping member 22 satisfy the above conditions, the fabric 100 can wrap around the outer periphery of the first clamping member 21 and the second clamping member 22, allowing the first clamping member 21 and the second clamping member 22 to clamp the fabric 100 more stably. This also facilitates the adhesion between adjacent loops formed by the winding of the fabric 100, creating friction between adjacent loops, thereby preventing the fabric 100 from being moved by external forces, and making the first clamping member 21 and the second clamping member 22 clamp the fabric 100 more stably.

[0045] For example, the rotation angle α of the first clamping member 21 and the second clamping member 22 can be 270°, 290°, 310°, 340° or 360°, etc.

[0046] For example, such as Figure 5 As shown, Figure 5 The diagram illustrates the winding of the fabric 100 when viewed along the rotation axis of the first clamp 21 and the second clamp 22, as they rotate to different angles. It is understood that this is done to clearly demonstrate the winding of the fabric 100. Figure 5 The spacing variation between the first clamping member 21 and the second clamping member 22 is not shown. Figure 5 Figure (d) is a schematic diagram of the winding of the fabric 100 when the first clamping member 21 and the second clamping member 22 rotate 270°. It can be seen that the inner and outer circles formed by the winding of the fabric 100 can fit together.

[0047] It is worth noting that the rotation angle α of the first clamping member 21 and the second clamping member 22 is the angle at which the fabric 100 is clamped and fixed by the rotation of the first clamping member 21 and the second clamping member 22 when the fabric 100 is located between the first clamping member 21 and the second clamping member 22. It does not limit the angle at which the first clamping member 21 and the second clamping member 22 can be relative to the support frame 1 when the fabric 100 is not placed between the first clamping member 21 and the second clamping member 22. Specifically, when the fabric 100 is not placed between the first clamping member 21 and the second clamping member 22, the first clamping member 21 and the second clamping member 22 can rotate freely about the rotation axis relative to the support frame 1, or the first clamping member 21 and the second clamping member 22 can rotate about the rotation axis about a preset angle relative to the support member.

[0048] like Figure 5 As shown, in some embodiments, the first clamping mechanism 2 has a first state, a second state, a third state, and a fourth state. In the first and third states, the first clamping member 21 and the second clamping member 22 are arranged along a first arrangement direction. In one of the first and third states, the first clamping member 21 is closer to the positive direction of the first arrangement direction relative to the second clamping member 22. In the other of the first and third states, the first clamping member 21 is further away from the positive direction of the first arrangement direction relative to the second clamping member 22. In the second and fourth states, the first clamping member 21 and the second clamping member 22 are arranged along a second arrangement direction perpendicular to the first arrangement direction. In one of the second and fourth states, the first clamping member 21 is closer to the positive direction of the second arrangement direction relative to the second clamping member 22. In the other of the second and fourth states, the first clamping member 21 is further away from the positive direction of the second arrangement direction relative to the second clamping member 22.

[0049] For example, the first arrangement direction can be a direction perpendicular to the first direction, such as... Figure 1 As shown in the Y0-Y1 direction, the second arrangement direction can be a direction parallel to the first direction, such as... Figure 1 The Z0-Z1 direction is shown in the figure.

[0050] For example, such as Figure 5 As shown, Figure 5 The diagram shows the relative positions of the first clamping members 21 and 22 of the two first clamping mechanisms 2 when rotated to different angles, as viewed along the rotation axis of the first clamping member 21 and the second clamping member 22. It is worth noting that... Figure 5 The spacing between the first clamping member 21 and the second clamping member 22 is not shown. The first arrangement direction can be horizontal, and the second arrangement direction can be vertical. The first state can be as follows: Figure 5As shown in Figure (a), the fabric 100 is located between the first clamping member 21 and the second clamping member 22. The first clamping member 21 and the second clamping member 22 are not rotated, and the third state can be as follows. Figure 5 As shown in Figure (c), the first clamping member 21 and the second clamping member 22 rotate 180° in the rotation direction. In the first and third states, the first clamping member 21 and the second clamping member 22 are arranged horizontally. Taking the leftward direction as the positive horizontal direction as an example, as... Figure 5 As shown in Figure (a), when the upper first clamping mechanism 2 is in the first state, the first clamping member 21 is closer to the positive direction of the horizontal direction relative to the second clamping member 22, as... Figure 5 As shown in Figure (c), when the upper first clamping mechanism 2 is in the third state, the first clamping member 21 is further away from the positive direction of the horizontal direction relative to the second clamping member 22. The second state can be as follows: Figure 5 As shown in Figure (b), the first clamping member 21 and the second clamping member 22 rotate 90° in the rotation direction, and the fourth state can be as follows: Figure 5 As shown in Figure (d), the first clamping member 21 and the second clamping member 22 rotate 270° in the rotation direction. In the second and fourth states, the first clamping member 21 and the second clamping member 22 are arranged vertically. Taking the upward vertical direction as the positive vertical direction as an example, as shown... Figure 5 As shown in Figure (b), when the upper first clamping mechanism 2 is in the second state, the first clamping member 21 is closer to the positive vertical direction relative to the second clamping member 22, as... Figure 5 As shown in Figure (d), when the upper first clamping mechanism 2 is in the fourth state, the first clamping member 21 is further away from the positive direction of the vertical direction relative to the second clamping member 22.

[0051] For example, the first clamping member 21 and the second clamping member 22 can rotate 360° in the rotation direction, and the first clamping member 21 and the second clamping member 22 can be switched to a first state, such as... Figure 5 As shown in Figure (d).

[0052] In some embodiments, when the two first clamping mechanisms 2 are in their initial state, i.e., when the two first clamping mechanisms 2 are not rotating to drive the fabric 100 to wind, the first clamping member 21 and the second clamping member 22 of the same first clamping mechanism 2 are arranged along the first fabric direction. The first clamping members 21 of the two first clamping mechanisms 2 are respectively located on opposite sides of the fabric 100 along the first fabric direction, and the second clamping members 22 of the two first clamping mechanisms 2 are respectively located on opposite sides of the fabric 100 along the first fabric direction. In other words, the two first clamping members 21 are separated by the fabric 100, and the two second clamping members 22 are separated by the fabric 100. Figure 5As shown in Figure (a), when viewed along the rotation axis of the first clamping member 21 and the second clamping member 22, the first clamping member 21 of the upper first clamping mechanism 2 is located on the left side of the fabric 100, the first clamping member 21 of the lower first clamping mechanism 2 is located on the right side of the fabric 100, the second clamping member 22 of the upper first clamping mechanism 2 is located on the right side of the fabric 100, and the second clamping member 22 of the lower first clamping mechanism 2 is located on the left side of the fabric 100.

[0053] In other embodiments, when the two first clamping mechanisms 2 are in the initial state, the first clamping member 21 and the second clamping member 22 of the same first clamping mechanism 2 are arranged along the first arrangement direction, and the first clamping member 21 of the two first clamping mechanisms 2 may also be located on the same side of the fabric 100 along the first arrangement direction, and the second clamping member 22 of the two first clamping mechanisms 2 may also be located on the same side of the fabric 100 along the first arrangement direction.

[0054] like Figure 5 As shown, in some embodiments, when the two first clamping mechanisms 2 are used to clamp and fix the fabric 100, the rotation directions of the two first clamping mechanisms 2 are opposite. In this way, the portion of the fabric 100 to be threaded between the positions clamped by the two first clamping mechanisms 2 is located on the same side of the two first clamping mechanisms 2, which facilitates subsequent tufting, embroidery or sewing on the portion to be threaded.

[0055] For example, such as Figure 5 As shown, the upper first clamping mechanism 2 rotates along the S0 direction, and the lower first clamping mechanism 2 rotates along the S1 direction, so that the portion of the fabric 100 to be threaded between the positions where it is clamped by the two first clamping mechanisms 2 is located to the left of the two first clamping mechanisms 2. The portion of the fabric 100 to be threaded is as follows: Figure 5 The dotted line indicates that this facilitates subsequent tufting, embroidery, or sewing on the fabric 100.

[0056] Of course, in other embodiments, when the two first clamping mechanisms 2 are used to clamp and fix the fabric 100, the rotation direction of the two first clamping mechanisms 2 may also be the same, and the specific adjustment can be made according to actual needs.

[0057] In some embodiments, such as Figure 5As shown in Figure (a), when the fabric 100 is placed between the first clamping member 21 and the second clamping member 22, both opposite ends of the fabric 100 extend out of the gap between the first clamping member 21 and the second clamping member 22. This helps to ensure that the first clamping member 21 and the second clamping member 22 clamp as much fabric 100 as possible in the end, ensuring the stability of the fabric 100 clamped by the first clamping member 21 and the second clamping member 22. Furthermore, when the rotation angle of the first clamping member 21 and the second clamping member 22 is greater than or equal to 270°, the adjacent loops formed by the winding of the fabric 100 are closely fitted, and there is friction between the adjacent loops, thereby preventing the fabric 100 from being moved by external forces, making the first clamping member 21 and the second clamping member 22 clamp the fabric 100 more stably.

[0058] For example, such as Figure 5 As shown, the first clamping member 21 has a first clamping plane 211, and the second clamping member 22 has a second clamping plane 221. The first clamping plane 211 and the second clamping plane 221 are arranged opposite to each other in the sliding direction of the second clamping member 22. The fabric 100 is placed between the first clamping plane 211 and the second clamping plane 221. The first clamping member 21 and the second clamping member 22 rotate to realize that the first clamping plane 211 and the second clamping plane 221 clamp the fabric 100.

[0059] Of course, in other embodiments, the first clamping member 21 may have a first clamping arc surface, and the second clamping member 22 may have a second clamping arc surface. The first clamping arc surface and the second clamping arc surface are arranged opposite to each other in the sliding direction of the second clamping member 22, and the fabric 100 is clamped by the first clamping arc surface and the second clamping arc surface.

[0060] like Figure 3 and Figure 4 As shown, in some embodiments, at least one of the first clamping member 21 and / or the second clamping member 22 has a protrusion 23 on its outer periphery. By providing the protrusion 23 on the outer periphery of the first clamping member 21 and the second clamping member 22, the first clamping member 21 and the second clamping member 22 can stretch the fabric 100 to compensate for the deformation that occurs when the fabric 100 fixing device is fixing and tightening the fabric 100, and to compensate for the positive Poisson shrinkage of the fabric 100, so that the fabric 100 is taut and the tension distribution is more uniform.

[0061] For example, such as Figure 3 As shown, both the first clamping member 21 and the second clamping member 22 have protrusions 23 on their outer peripheries, and the protrusions 23 extend along the axis of the rotation direction of the first clamping member 21 and the second clamping member 22.

[0062] like Figures 2 to 4As shown, in some embodiments, the support frame 1 includes a first support member 11 and a second support member 12, which are arranged opposite to each other along a second direction perpendicular to the first direction. The second support member 12 is provided with a first mounting hole 12a, which penetrates both opposite sides of the second support member 12 along the second direction. The first clamping mechanism 2 also includes a first connector and a second connector 24. The first connector is rotatably connected to the first support member 11, one end of the first clamping member 21 is connected to the first connector, one end of the second clamping member 22 is slidably connected to the first connector, the second connector 24 is rotatably connected to the first mounting hole 12a, the other end of the first clamping member 21 is connected to the second connector 24, and the other end of the second clamping member 22 is slidably connected to the second connector 24.

[0063] Understandably, the first clamping member 21 and the second clamping member 22 are connected to the first connecting member, the first connecting member is rotatably connected to the first support member 11, the first clamping member 21 and the second clamping frame are both connected to the second connecting member 24, and the second connecting member 24 is rotatably connected to the second support member 12, thereby realizing the rotatable connection between the first clamping mechanism 2 and the support frame 1. Furthermore, by driving one of the second connecting members 24 to move, the first clamping member 21 and the second clamping member 22 can be driven to rotate, simplifying the transmission structure of the fabric 100 fixing device, making the structure of the fabric 100 fixing device compact, improving the synchronicity of the movement of the first clamping member 21 and the second clamping member 22, and facilitating the rotation of the first clamping member 21 and the second clamping member 22 to clamp the fabric 100. In addition, a first mounting hole 12a is provided in the second support member 12, so that the second connector 24 is exposed, which makes it easier to apply force to the second connector 24. At the same time, the force application position can be far away from the first clamping member 21 and the second clamping member 22, avoiding obstruction to the rotation of the first clamping member 21 and the second clamping member 22, and reducing the structural complexity of driving the first clamping mechanism 2 to rotate.

[0064] For example, the second direction can be as follows Figure 1 The X0-X1 direction is shown in the figure.

[0065] For example, the first clamping member 21 may be a hollow clamping member, and the first connecting member and the second connecting member 24 are provided with protruding extensions 241, which pass through the first clamping member 21 to facilitate the connection between the first connecting member and the first clamping member 21, and the connection between the second connecting member 24 and the first clamping member 21. Furthermore, the first connecting member and the second connecting member 24 are provided with sliding grooves, and the opposite ends of the second clamping member 22 can be slidably engaged with the sliding grooves of the first connecting member and the second connecting member 24, respectively, to facilitate the sliding connection between the first connecting member and the second clamping member 22, and the sliding connection between the second connecting member 24 and the second clamping member 22.

[0066] In some embodiments, the fabric 100 fixing device includes a drive mechanism that is tractively connected to the second connecting members 24 of the two first clamping mechanisms 2. The drive mechanism drives the second connecting members 24 to rotate, thereby causing the second connecting members 24 to drive the corresponding first clamping members 21 and second clamping members 22 to rotate.

[0067] like Figures 1 to 4 As shown, in some embodiments, the fabric 100 fixing device further includes two first transmission mechanisms 3, each of which includes a first operating member 31, which is tractively connected to the second connecting member 24. Thus, the user can manipulate the first operating member 31 to drive the first clamping mechanism 2 to rotate.

[0068] It is worth noting that the order in which the user operates the two first operating components 31 can be adjusted according to the actual situation, and is not limited here. For example, the user can operate the first operating components 31 of the two first clamping mechanisms 2 simultaneously, so that the two first clamping mechanisms 2 rotate synchronously to clamp and fix the fabric 100 at two positions. Alternatively, the user can first operate the first operating component 31 of one of the first clamping mechanisms 2, so that the first clamping mechanism 2 rotates to clamp and fix the fabric 100 at one position, and then operate the first operating component 31 of the other first clamping mechanism 2, so that the other first clamping mechanism 2 rotates to clamp and fix the fabric 100 at another position.

[0069] For example, the first operating element 31 includes a handwheel, a joystick, etc.

[0070] In some embodiments, at least one of the two first transmission mechanisms 3 includes a reduction gear 32, which is drively connected to the first operating member 31 and the second connecting member 24. The reduction gear 32 reduces speed and increases torque, amplifying the force exerted on the first operating member 31 when the user operates it, making it easier for the user to operate the first operating member 31 to drive the second connecting member 24 to rotate.

[0071] Furthermore, the reduction assembly 32 includes a gear set, which is connected to the first operating member 31 and the second connecting member 24. By meshing gears with different numbers of teeth, the high speed and low torque of the first operating member 31 are converted into the low speed and high torque of the second connecting member 24, thereby achieving speed reduction and torque increase.

[0072] like Figure 3As shown, specifically, the reduction assembly 32 includes a planetary carrier 321, a sun gear 322, and planetary gears 323. The planetary carrier 321 is drivenly connected to the second connecting member 24. The sun gear 322 is rotatably connected to the side of the planetary carrier 321 away from the second connecting member 24, and is drivenly connected to the first operating member 31. The planetary gears 323 are rotatably connected to the side of the planetary carrier 321 away from the second connecting member 24. The planetary gears 323 mesh with the sun gear 322, and can rotate around the sun gear to drive the planetary carrier 321 to rotate around the axis of the sun gear 322. The sun gear 322 and planetary gears 323 not only achieve speed reduction and torque increase, but also contribute to a compact overall structure of the reduction assembly 32.

[0073] For example, there may be one or more planetary gears 323. Figure 3 As shown, there are three planetary gears 323, which are evenly spaced on the outer periphery of the sun gear 322, and the three planetary gears 323 mesh with the sun gear 322 respectively.

[0074] In some embodiments, the rotation axis of the first operating member 31 and the rotation axis of the sun gear 322 are collinear, so that the first operating member 31 can drive the sun gear 322 to rotate.

[0075] In some embodiments, the first operating member 31 is located on the side of the sun gear 322 away from the second connecting member 24. The first operating member 31 is provided with a first tooth groove, and the sun gear 322 is partially inserted into the first tooth groove to realize the transmission connection between the first operating member 31 and the sun gear 322. The first operating member 31 can drive the sun gear 322 to rotate.

[0076] In some embodiments, the first operating member 31 can be fastened to the sun gear 322 by fasteners to realize the transmission connection between the first operating member 31 and the sun gear 322, and the first operating member 31 can drive the sun gear 322 to rotate.

[0077] In some embodiments, the rotation axis of the planetary carrier 321 and the rotation axis of the sun gear 322 are configured to achieve a compact overall structure for the reduction gear assembly 32.

[0078] In some embodiments, the reduction assembly 32 further includes an internal gear ring 324. The internal gear ring 324 is provided on the side of the second support member 12 away from the first support member 11, and the internal gear ring 324 is arranged around the outer periphery of the first mounting hole 12a. By providing the internal gear ring 324, the internal gear protects the sun gear 322 and the planetary gear 323, while improving the activity stability of the planetary gear 323.

[0079] In some embodiments, the first operating member 31 is rotatably sleeved on the outer periphery of the inner gear ring 324, and the first operating member 31 can rotate around the inner gear ring 324, limiting the rotation direction of the first operating member 31, so that the rotation of the first operating member 31 is more stable.

[0080] like Figure 3 and Figure 4 As shown, in some embodiments, the second support member 12 has a boss 121 on the side away from the first support member 11. The boss 121 is arranged around the outer periphery of the first mounting hole 12a. The first operating member 31 is rotatably sleeved on the outer periphery of the boss 121, so that the first operating member 31 can rotate around the boss 121, limiting the rotation direction of the first operating member 31 and making the rotation of the first operating member 31 more stable.

[0081] For example, the boss 121 may be located on the outer periphery of the internal gear ring 324.

[0082] like Figure 4 As shown, in some embodiments, the first transmission mechanism 3 includes a first operating member 31 and a transmission assembly 33. The transmission assembly 33 is tractively connected to the second connecting member 24. One of the first operating member 31 and the transmission assembly 33 is provided with a first gear portion, and the other is provided with a second tooth groove. The first gear portion is inserted into the second tooth groove, so that the first operating member 31 and the transmission assembly 33 are tractively connected. The first operating member 31 can smoothly drive the transmission assembly 33 to rotate, thereby driving the first clamping mechanism 2 to rotate.

[0083] like Figure 3 and Figure 4 As shown, in some embodiments, the fabric 100 fixing device further includes a locking mechanism 4. One of the second support member 12 and the first operating member 31 is connected to the locking mechanism 4, and the other of the second support member 12 and the first operating member 31 can be engaged with or disengaged from the locking mechanism 4. It is understood that when the other of the second support member 12 and the first operating member 31 is disengaged from the locking mechanism 4, the first operating member 31 can drive the second connecting member 24 to rotate. When the other of the second support member 12 and the first operating member 31 is engaged with the locking mechanism 4, the first operating member 31 is locked, so that after the first operating member 31 drives the first clamping mechanism 2 to rotate, it remains at a certain angle, allowing the first clamping member 21 and the second clamping member 22 to stably clamp the fabric 100.

[0084] For example, there are two locking mechanisms 4, which are used to lock the first operating member 31 of different first clamping mechanisms 2 respectively.

[0085] In some embodiments, when the first operating member 31 is rotated to a preset angle, the other of the second support member 12 and the first operating member 31 can cooperate with the locking mechanism 4 to lock the first operating member 31. Alternatively, when the first operating member 31 is rotated to any angle, the other of the second support member 12 and the first operating member 31 can cooperate with the locking mechanism 4 to lock the first operating member 31.

[0086] like Figure 3 and Figure 4 As shown, in some embodiments, the locking mechanism 4 includes a ratchet 41, a locking member 42, and an elastic member 43. One of the second support member 12 and the first operating member 31 is provided with the ratchet 41, and the locking member 42 is provided with a pawl 421. The locking member 42 is movably connected to the other of the second support member 12 and the first operating member 31. The elastic member 43 is connected to the one of the second support member 12 and the first operating member 31 that is movably connected to the locking member 42, and is also connected to the locking member 42. When it is necessary to unlock the first operating member 31, the locking member 42 can be controlled to compress the elastic member 43 and move relative to the first operating member 31 or the second support member 12, causing the pawl 421 to separate from the ratchet 41, thereby allowing the first operating member 31 to rotate. When it is necessary to lock the first operating member 31, the external force applied to the locking member 42 is removed, and the pawl 421 can automatically engage with the ratchet 41 under the elastic force of the elastic member 43, thus locking the first operating member 31.

[0087] For example, the elastic element 43 includes, but is not limited to, a sheet, a spring, etc.

[0088] like Figure 3 and Figure 4 As shown, the ratchet 41 further includes an internal toothed ratchet. The first operating member 31 includes a connecting portion 311 and an annular portion 312 surrounding the connecting portion 311. The locking member 42 is slidably connected to the connecting portion 311. The annular portion 312 is provided with a second mounting hole 312a. The locking member 42 at least partially passes through the second mounting hole 312a and is located outside the first operating member 31. By allowing the locking member 42 to slide slidably connect to the first operating member 31 and extend at least partially outside the first operating member 31, when the user holds the first operating member 31, a portion of the hand presses on the locking member 42, causing the locking member 42 to overcome the elastic force and compress the elastic member 43. The locking member 42 slides relative to the first operating member 31, causing the pawl 421 to separate from the ratchet 41, thereby unlocking the first operating member 31. Then, the user can rotate the first operating member 31 while keeping it unlocked. In other words, the user can hold the first operating member 31 to unlock and rotate it, which is convenient and simplifies the operation. The pawl 421 separates from the ratchet 41 to unlock, making it convenient for the user to unlock and rotate the first operating member 31 with one hand.

[0089] For example, the pawl 421 protrudes from the locking member 42 and is located inside the ratchet 41, so that the pawl 421 can slide with the locking member 42 to engage or disengage with the ratchet 41, and can prevent the locking member 42 from disengaging from the first operating member 31 and the ratchet 41.

[0090] Combination Figure 7 As shown, in some embodiments, the connecting portion 311 includes a first portion 3111 and a second portion 3112. The second portion 3112 protrudes from the first portion 3111, and the annular portion 312 surrounds the outer periphery of the first portion 3111 and the second portion 3112 and is connected to the first portion 3111. The annular portion 312 and the second portion 3112 are spaced apart. The locking member 42 is located on the outer periphery of the second part 3112 and passes through the second mounting hole 312a of the annular part 312. The locking member 42 or the pawl 421 is provided with a first mounting groove 42a on the side facing the second part 3112, and the second part 3112 is provided with a second mounting groove 3112a on the side facing the locking member 42. The opposite ends of the elastic member 43 can respectively extend into the first mounting groove 42a and the second mounting groove 3112a. The relative position of the elastic member 43 is restricted by the first mounting groove 42a and the second mounting groove 3112a, thereby improving the stability of the elastic member 43 and simplifying the connection structure between the elastic member 43, the locking member 42 and the first operating member 31.

[0091] like Figure 3 As shown, in some embodiments, the ratchet 41 includes an internal gear ratchet, and the ratchet 41 and the internal gear ring 324 are arranged sequentially along the second direction. The sun gear 322 is connected to the first operating member 31 through the hollow part of the ratchet 41. The locking member 42 may be located on the outer periphery of the second part 3112 of the sun gear 322 or the first operating member 31 connected to the sun gear 322, making the structure of the fabric 100 fixing device more compact.

[0092] like Figure 1 and Figure 2 As shown, in some embodiments, the fabric 100 fixing device further includes a feeding member 5, which is rotatably connected to the support frame 1. The fabric 100 can be wound around the outer periphery of the feeding member 5. It can be understood that when the fabric 100 is long, the fabric 100 can be wound around the outer periphery of the feeding member 5. After unwinding as needed, the fabric 100 is clamped by two first clamping mechanisms 2. Then, tufting, embroidery, etc., are performed on the part of the fabric 100 to be threaded. The area of ​​the part to be threaded can be adjusted at any time by unwinding the fabric 100.

[0093] For example, the opposite ends of the feeding component 5 can be rotatably connected to the first support component 11 and the second support component 12, respectively. Specifically, the first support component 11 is provided with a first notch, and the second support component 12 is provided with a second notch. The opposite ends of the feeding component 5 can be rotatably engaged with the first notch and the second notch, respectively, so as to realize the rotatable connection between the feeding component 5 and the support frame 1, while restricting the rotation direction of the feeding component 5.

[0094] Specifically, the position of the material placement component 5 can be adjusted according to actual needs. For example... Figure 2 As shown, the feeding component 5 can be located on one side of the two first clamping mechanisms 2 along the Z0-Z1 direction, or the feeding component 5 can be located on one side of the first clamping mechanism 2 along the Y0-Y1 direction.

[0095] like Figure 2 , Figures 8 to 11 As shown, in some embodiments, the fabric 100 fixing device further includes two second clamping mechanisms 6. Each second clamping mechanism 6 includes a third clamping member 61 and a fourth clamping member 62. The third clamping members 61 of the two second clamping mechanisms 6 are respectively connected to opposite sides of the support frame 1 along a second direction, which is perpendicular to the first direction. The fourth clamping member 62 is movably connected to the third clamping member 61, allowing the fourth clamping member 62 to switch between clamping and releasing the fabric 100 with the third clamping member 61. Thus, the two second clamping mechanisms 6 can clamp the fabric 100 at two locations along the second direction, thereby clamping the surrounding area of ​​the portion of the fabric 100 to be threaded, making the portion of the fabric 100 to be threaded more secure and facilitating subsequent tufting, embroidery, or sewing on the portion of the fabric 100 to be threaded.

[0096] Understandably, the two second clamping mechanisms 6 are located between the two first clamping mechanisms 2, or the two first clamping mechanisms 2 are located between the two second clamping mechanisms 6, such that the two first clamping mechanisms 2 and the two second clamping mechanisms 6 clamp the four sides of the portion of the fabric 100 to be threaded.

[0097] For example, the third clamping member 61 and the fourth clamping member 62 may slide relative to each other, or the third clamping member 61 and the fourth clamping member 62 may rotate relative to each other.

[0098] like Figure 8 and Figure 9As shown, in some embodiments, at least one third clamping member 61 in the second clamping mechanism 6 includes a first rotating portion 611 and a first engaging portion 612 connected to the outer periphery of the first rotating portion 611. The fourth clamping member 62 includes a second rotating portion 621 and a second engaging portion 622 connected to the outer periphery of the second rotating portion 621. One of the first engaging portion 612 and the second engaging portion 622 is provided with a slot 612a. The first rotating portion 611 and the second rotating portion 621 are rotatably connected so that the other of the first engaging portion 612 and the second engaging portion 622 can engage with the slot 612a or separate from the slot 612a. It can be understood that when the other of the first engaging portion 612 and the second engaging portion 622 engages with the slot 612a, the fabric 100 can be clamped tightly in the slot 612a, so that the fabric 100 is stably clamped by the third clamping member 61 and the fourth clamping member 62. When the other of the first latching portion 612 and the second latching portion 622 separates from the slot 612a, the fabric 100 is released, allowing the fabric 100 to be disengaged or moved between the third clamping member 61 and the fourth clamping member 62. Furthermore, the relative rotation of the first and second latching members and the relatively small range of motion of the third clamping member 61 and the fourth clamping member 62 facilitate a compact structural design of the fabric 100 fixing device when the second clamping mechanism 6 is applied to the fabric 100 fixing device.

[0099] For example, the second rotating part 621 is disposed around the outer periphery of the first rotating part 611, and the second rotating part 621 is capable of rotating around the first rotating part 611, such as... Figure 8 and Figure 9 As shown. Alternatively, the first rotating part 611 is disposed around the outer periphery of the second rotating part 621, and the first rotating part 611 is capable of rotating around the second rotating part 621.

[0100] For example, such as Figure 8 As shown, the first rotating part 611 includes a rotating shaft, and the second rotating part 621 includes an open-loop structure. The open-loop structure is disposed around the outer periphery of the rotating shaft, allowing the second rotating part 621 to rotate around the first rotating part 611, thereby realizing the relative rotation of the third clamping member 61 and the fourth clamping member 62. For example, as... Figure 8 As shown, the rotating shaft can be a circular shaft, and the open-loop structure can be a circular ring structure larger than a semicircle, so that the open-loop structure is stably wrapped around the outer circumference of the rotating shaft, preventing the open-loop structure from detaching from the rotating shaft under the action of external force.

[0101] For example, the first engaging portion 612 can be connected to the outer periphery of the rotating shaft, and a slot 612a is formed on one side of the first engaging portion 612 along the rotation direction of the fourth clamping member 62. The second engaging portion 622 is connected to the outer periphery of the open-loop structure, and the second rotating portion 621 rotates around the first rotating portion 611, so that the second engaging portion 622 can engage with the slot 612a, or so that the second engaging portion 622 can separate from the slot 612a.

[0102] For example, such as Figure 7 As shown, the third clamping member 61 and the fourth clamping member 62 extend along the axis of the rotation direction to increase the area of ​​the fabric 100 clamped by the third clamping member 61 and the fourth clamping member 62, so that the third clamping member 61 and the fourth clamping member 62 stably clamp the fabric 100.

[0103] As shown in Figure 8 and Figure 9 As shown, Figure 8 The image shows the fabric 100 in an unclamped state. Figure 9 The diagram shows the fabric 100 in a clamped state. In some embodiments, the fabric 100 is located outside the first rotating part 611 and the second rotating part 621, and the first snap-fit ​​part 612 and the second snap-fit ​​part 622 clamp the fabric 100 to ensure a stable connection between the first rotating part 611 and the second rotating part 621 and to prevent the fabric 100 from affecting the relative movement between the first rotating part 611 and the second rotating part 621.

[0104] For example, such as Figure 8 As shown, the shapes of the first rotating part 611 and the second rotating part 621 are matched. For example, the first rotating part 611 is a circular shaft and the second rotating part 621 is a circular ring structure, so that when the second rotating part 621 is wrapped around the outer periphery of the first rotating part 611, the fabric 100 is difficult to extend between the first rotating part 611 and the second rotating part 621.

[0105] like Figure 8 and Figure 9 As shown, in some embodiments, an operating part 623 is provided on the side of the second engaging portion 622 away from the second rotating portion 621. When the second engaging portion 622 is engaged in the slot 612a, the operating part 623 is located outside the slot 612a. Thus, when it is necessary to rotate the fourth clamping member 62 relative to the third clamping member 61 to separate the second engaging portion 622 from the slot 612a, the user can operate the operating part 623. Furthermore, the operating part 623 is away from the second rotating portion 621, and the force applied to the operating part 623 when the user operates it has a component force along the rotation direction of the fourth clamping member 62, making it easier for the user to operate the operating part 623.

[0106] For example, the operation unit 623 may be as follows: Figure 8 The arc-shaped structure shown has an inwardly concave arc surface that extends away from the slot 612a, allowing the user's hand to rest stably against the arc surface and apply force to operate the control unit 623, thus facilitating user operation. Of course, in other examples, the control unit 623 can also be a straight structure; the specific design can be adjusted according to the actual situation and is not limited here.

[0107] like Figure 8 and Figure 9As shown, in some embodiments, the slot 612a has two opposing sidewalls 61201 and a bottom wall 61202 connecting the two sidewalls 61201. One of the two sidewalls 61201 is close to the first rotating part 611, and the other is away from the first rotating part 611. At least one sidewall 61201 is provided with a limiting part 613, and the second engaging part 622 forms a limiting groove 622a. When the second engaging part 622 engages with the slot 612a, the limiting part 613 can engage with the limiting groove 622a. Understandably, in addition to being clamped in the slot 612a by the second snap-fit ​​part 622, the fabric 100 can also be clamped in the limiting groove 622a by the limiting part 613, thereby achieving multiple clamping of the fabric 100, improving the clamping stability of the fabric 100 by the second clamping mechanism 6, and also making the snap-fit ​​between the second snap-fit ​​part 622 and the slot 612a more stable.

[0108] For example, such as Figure 8 As shown, the two sidewalls 61201 are the first sidewall and the second sidewall, respectively. The first sidewall is positioned close to the first rotating part 611, while the second sidewall is positioned away from the first rotating part 611. A limiting part 613 protrudes from the second sidewall towards the first sidewall. A limiting groove 622a is formed on the side of the second engaging part 622 away from the second rotating part 621. When the third clamping member 61 and the fourth clamping member 62 rotate relative to each other, the second engaging part 622 engages with the groove 612a, and the limiting part 613 can engage within the limiting groove 622a. Figure 8 As shown. By forming a limiting groove 622a on one side of the second rotating part 621 based on the principle of the second snap-fit ​​part 622, and providing a limiting part 613 on the second side wall away from the first rotating part 611, it is more conducive to restricting the relative rotation of the first rotating part 611 and the second rotating part 621, so that the clamping of the fabric 100 by the third clamping member 61 and the fourth clamping member 62 is more stable.

[0109] For example, the limiting part 613 may be a conical structure with its tip pointing towards the bottom wall surface 61202, and the limiting groove 622a is a matching conical groove, so that the limiting part 613 can be more stably engaged in the limiting groove 622a.

[0110] Optionally, the limiting groove 622a can be formed by thinning a portion of the second latching portion 622, or the limiting groove 622a can be formed in the center of the protrusion by making a portion of the second latching portion 622 protrude. The specific method can be adjusted according to the actual situation and is not limited here.

[0111] like Figure 8As shown, further, there are multiple limiting portions 613, which are arranged sequentially along the direction from the side wall surface 61201 to the bottom wall surface 61202. There are multiple limiting grooves 622a, and when the second engaging portion 622 engages with the groove 612a, the multiple limiting portions 613 are engaged with the multiple limiting grooves 622a respectively. In this way, the magnitude of the force required for the second engaging portion 622 to separate from the groove 612a can be increased, so that the first engaging portion 612 and the second engaging portion 622 can more stably clamp the fabric 100.

[0112] As shown in the figure, in some embodiments, the first rotating part 611 and the second rotating part 621 are rotatably connected, and the limiting part 613 and the limiting groove 622a can extend along the rotation direction to increase the area of ​​clamping the fabric 100, so that the limiting part 613 and the limiting groove 622a stably clamp the fabric 100.

[0113] In some embodiments, the first rotating part 611 and the second rotating part 621 are rotatably connected, a plurality of limiting grooves 622a are arranged sequentially along the rotation direction, a plurality of limiting parts 613 are arranged at intervals along the rotation direction, and the plurality of limiting parts 613 can be respectively engaged in the corresponding limiting grooves 622a.

[0114] In some embodiments, the second engaging portion 622 includes an elastically deformable member 6221, the deformable member 6221 having a second limiting portion 613, the deformable member 6221 having an elastic force pointing towards the side wall surface 61201, so that the limiting portion 613 is stably engaged in the limiting groove 622a.

[0115] like Figure 8 As shown, the deformable part further includes a serpentine spring, which allows the deformable part to deform in the direction from the second engaging part 622 to the second rotating part 621, and has an elastic force pointing towards the side wall surface 61201 when engaged in the slot 612a.

[0116] For example, such as Figure 8 As shown, the deformable part includes a serpentine spring. The serpentine spring extends continuously in a direction away from the second rotating part 621, and a limiting groove 622a is formed at one end of the serpentine spring relative to the second rotating part 621. A limiting part 613 is provided on the second side wall. When the limiting part 613 is engaged with the limiting groove 622a, the serpentine spring has an elastic force pointing towards the second side wall, so that the limiting part 613 is stably engaged with the limiting groove 622a.

[0117] In some embodiments, the deformable part can be made of an elastic material so that when the deformable part is engaged in the slot 612a, it has an elastic force pointing towards the side wall 61201.

[0118] like Figure 10As shown, in some embodiments, the first rotating part 611 or the second rotating part 621 is provided with a third mounting hole 611a. The third mounting hole 611a is used for the support frame 1 to pass through, so that the second clamping mechanism 6 can rotate around the predetermined component, thereby pulling the fabric 100 and making the fabric 100 taut, which facilitates subsequent tufting, embroidery and other processes on the fabric 100.

[0119] For example, the first rotating part 611 is provided with a third mounting hole 611a, and the third mounting hole 611a passes through the opposite ends of the first rotating part 611 along the rotation direction, thereby reducing the weight of the second clamping mechanism 6. The support frame 1 can extend into the opposite ends of the third mounting hole 611a respectively, so that the first rotating part 611 can rotate stably relative to the support frame 1.

[0120] like Figure 2 , Figure 10 and Figure 11 As shown, in some embodiments, at least one third clamping member 61 of the second clamping mechanism 6 is rotatably connected to the support frame 1. The fabric 100 fixing device also includes a second transmission mechanism 7, which is tractively connected to the third clamping member 61. The second transmission mechanism 7 can drive the second clamping mechanism 6 to rotate around a first direction. It can be understood that there is at least one second transmission mechanism 7. When the fourth clamping member 62 and the third clamping member 61 of the second clamping mechanism 6 clamp the fabric 100 at two locations, the second transmission mechanism 7 can drive the third clamping member 61 and the fourth clamping member 62 to rotate around the first direction, so that the fabric 100 is further tightened.

[0121] For example, there may be one or more second transmission mechanisms 7. For instance, two second transmission mechanisms 7 are respectively connected to the third clamping members 61 of two second clamping mechanisms 6, thereby driving the two second clamping mechanisms 6 to rotate in opposite directions, thereby tightening the fabric 100.

[0122] like Figure 10 and Figure 11As shown, in some embodiments, the third clamping member 61 has a first inclined surface 61101 that is tilted relative to the first direction. The second transmission mechanism 7 includes a sliding member 71, which is slidably connected to the support frame 1. The sliding member 71 abuts against the first inclined surface 61101. The sliding member 71 can slide relative to the support frame 1 in the first direction and relative to the first inclined surface 61101, so as to rotate the third clamping member 61 and the fourth clamping member 62. It can be understood that when the sliding member 71 abuts against the first inclined surface 61101 and the sliding member 71 is pressed to slide in the first direction, the sliding member 71 applies a force to the first inclined surface 61101. The force applied by the sliding member 71 to the first inclined surface 61101 includes a component force along the rotation direction of the third clamping member 61, thereby causing the third clamping member 61 to drive the fourth clamping member 62 to rotate, thereby pulling the fabric 100 in. The rotation of the second clamping mechanism 6 can be controlled by pressing the sliding member 71, which is convenient for user operation and reduces the difficulty of operation.

[0123] For example, the first rotating part 611 of the third clamping member 61 has a first inclined surface 61101.

[0124] like Figure 10 and Figure 11 As shown, the third clamping member 61 further includes a spiral groove 611b. The spiral groove 611b has a first inclined surface 61101 and a second inclined surface 61102 arranged opposite to each other. The sliding member 71 is movably engaged between the first inclined surface 61101 and the second inclined surface 61102, allowing the sliding member 71 to remain at any position within the spiral groove 611b. It is understood that by controlling the extension direction of the spiral groove 611b, the tilt angles of the first inclined surface 61101 and the second inclined surface 61102 can be adjusted, thereby allowing the sliding member 71 to remain at any position within the spiral groove 611b under the engaging action of the first inclined surface 61101 and the second inclined surface 61102, achieving locking of the sliding member 71, facilitating user operation, and reducing operational difficulty.

[0125] For example, when the slider 71 slides relative to the support frame 1 in the positive direction of the first direction, such as along... Figure 1 When sliding in the Z1 direction, the slider 71 applies force to the first inclined surface 61101, causing the third clamping member 61 and the fourth clamping member 62 to tighten the fabric 100 while clamping it. When the slider 71 slides in the opposite direction to the support frame 1 in the first direction, for example along... Figure 1When sliding in the Z0 direction, the slider 71 applies force to the second inclined surface 61102, causing the parts of the third clamping member 61 and the fourth clamping member 62 used to clamp the fabric 100 to get closer to the fabric 100, so that the third clamping member 61 and the fourth clamping member 62 can clamp the fabric 100, or, while clamping the fabric 100, the third clamping member 61 and the fourth clamping member 62 can release the tension on the fabric 100, so that the third clamping member 61 and the fourth clamping member 62 can release the fabric 100.

[0126] For example, such as Figure 10 and Figure 11 As shown, the slider 71 includes a pressing part 711 and a sliding part 712. The support frame 1 is provided with a first slide groove 1a extending in a first direction. The third clamping member 61 is provided with a second slide groove, which is a spiral groove 611b. The sliding part 712 is slidably connected to the first slide groove 1a and the second slide groove. The pressing part 711 is connected to the sliding part 712. The pressing part 711 is at least partially located on the outer periphery of the third clamping member 61, or at least partially located on the outer periphery of the support frame 1, so as to facilitate the user to press.

[0127] For example, the pressing part 711 is engaged with the sliding part 712, simplifying the connection structure between the pressing part 711 and the sliding part 712.

[0128] like Figure 11 As shown, for example, the slider 71 is movably engaged with the support frame 1, allowing the sliding frame to slide relative to the support frame 1 while limiting the sliding of the slider 71 to prevent the slider 71 from dislodging from the support frame 1. For example Figure 11 As shown, the first groove 1a is a T-shaped groove. The pressing part 711 and the sliding part 712 include a T-shaped structure that matches the T-shaped groove. The T-shaped structure is slidably engaged with the T-shaped groove, which restricts the relative position of the sliding member 71 and the support frame 1 and improves the activity stability of the sliding member 71.

[0129] In some embodiments, the slider 71 can also lock when it slides along the first inclined surface 61101 to a preset position.

[0130] For example, when the slider 71 slides relative to the support frame 1 to the first position, the third clamping member 61 and the fourth clamping member 62 pull the fabric 100 to make the fabric 100 taut, and the slider 71 can engage with the support frame 1, so that the slider 71 is held in the first position, and the third clamping member 61 and the fourth clamping member 62 keep the fabric 100 taut. Then, the slider 71 can disengage from the support frame 1 under the action of external force, so that the slider 71 can slide relative to the support frame 1 to the second position. The slider 71 can engage with the support frame 1, so that the fabric 100 is not stretched in the second direction and is held by the third clamping member 61 and the fourth clamping member 62. After the third clamping member 61 and the fourth clamping member 62 hold the fabric 100, the slider 71 can disengage from the support frame 1 under the action of external force, so that the slider 71 slides relative to the support frame 1 to the first position.

[0131] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the fabric 100 fixing device further includes a third clamping mechanism 8, which is disposed on the support frame 1 and is used to clamp a preset component to fix the fabric 100 fixing device.

[0132] For example, the preset components include a tabletop, a shelf, etc.

[0133] Specifically, the position of the third clamping mechanism 8 can be adjusted according to actual needs, and is not limited here. For example Figure 1 As shown, the third clamping mechanism 8 can be located on one side of the support frame 1 along the Z0-Z1 direction, or the material feeding component 5 can be located on one side of the first clamping mechanism 2 along the X0-X1 direction.

[0134] For example, the third clamping mechanism 8 includes a fifth clamping member 81 and a sixth clamping member 82. The fifth clamping member 81 is connected to the support frame 1, and the sixth clamping member 82 is connected to the fifth clamping member 81 by an adjusting screw 83. Rotating the adjusting screw 83 can adjust the distance between the fifth clamping member 81 and the sixth clamping member 82, so that the fifth clamping member 81 and the sixth clamping member 82 can clamp a predetermined component or release the predetermined component.
