Description

Technical Field

[0001] This utility model relates to the field of fabric production technology, and in particular to a waste edge cutting device for the weaving process. Background Technology

[0002] During the fabric production process, after the initial weaving on the loom, the edges of the fabric inevitably have waste edges or frayed edges. If these waste edges are not removed in time, they will affect the quality and appearance of the fabric. Therefore, removing waste edges can ensure the neatness and consistency of the fabric, thereby improving product quality.

[0003] In existing technologies, removing fabric scraps typically involves fixing a blade directly to the side of the machine tool and cutting off the scraps. However, because fabric scraps are usually rough and soft, the blade cannot completely remove them, resulting in poor trimming and uneven fabric edges. Furthermore, the removed fabric scraps scatter into fine fibers, which are difficult to remove from the fabric or machinery, polluting the environment and wasting raw materials, which contradicts the principles of environmental protection and sustainable development.

[0004] Therefore, this utility model provides a device that can effectively remove fabric scraps. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a waste edge cutting device for the weaving process, which solves the problem that existing fabric trimming methods cannot neatly remove fabric waste edges.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A waste edge cutting device for the weaving process includes a mounting platform, a movable plate slidably disposed on the mounting platform, a blade assembly mounted on the movable plate, and a power assembly being drivenly connected to the blade assembly.

[0008] In this solution, the moving plate is moved along the mounting platform so that the blade assembly on its top is close to the waste edge of the fabric. The power unit drives the blade assembly to rotate, and the waste edge of the fabric is cut off during the rotation. The resulting fabric has a neat and consistent boundary, which improves product quality.

[0009] Furthermore, the blade assembly includes a shaft holder mounted on a movable plate; a rotating shaft is movably connected in a shaft hole at the top of the shaft holder, and a rotating blade is connected to the rotating shaft on the side near the waste edge of the fabric.

[0010] A rectangular hole is provided on the movable plate located directly below the rotating blade, and the edge of the rotating blade is located inside the rectangular hole.

[0011] In this solution, the rotating blade rotates rapidly around the rotating axis. As the fabric passes over the moving plate during rotation, its waste edges are quickly cut off, resulting in high waste edge removal efficiency.

[0012] Furthermore, a stepped groove is provided on the edge of the rectangular hole near the waste edge of the fabric, and a blade rest is placed in the stepped groove; the two ends of the blade rest are fixed in the stepped groove by two pressing blocks; the pressing blocks are installed on the side of the stepped groove by bolts.

[0013] In this design, a blade rest is designed inside the rectangular hole. The waste edge of the fabric is cut by the shearing action of the blade and the blade rest, ensuring the sharpness of the blade. At the same time, it avoids the waste edge of the fabric acting on the moving plate during cutting, which would cause severe wear on the edge of the rectangular hole.

[0014] Furthermore, two pressing rollers are installed on the movable plate, and the two pressing rollers are respectively distributed on both sides along the long side of the rectangular hole.

[0015] In this design, the two pressing rollers can make the fabric flatter, ensuring that the edges of the fabric lie flat on the moving plate when the rotating blade cuts.

[0016] Furthermore, the pressing roller includes a mounting base, which is fixed to the top of the movable plate by bolts; a roller shaft is movably connected to the mounting base, and the roller body is connected to the side of the roller shaft near the waste edge of the fabric.

[0017] In this design, the roller body is fixed only by a mounting base on one side, while the other side can be used for the fabric to pass through.

[0018] Furthermore, a groove is provided on the top of the mounting platform, and the movable plate is slidably disposed inside the groove;

[0019] The top of the movable plate has a threaded hole, and a positioning bolt is installed in the threaded hole. The positioning bolt passes through the threaded hole and abuts against the bottom of the slide.

[0020] In this solution, the movable plate is pushed along the chute until it is positioned so that the rotating blade can completely cut the waste edge of the fabric. After moving, the positioning bolts are tightened to fix the movable plate inside the chute, preventing it from moving during cutting.

[0021] Furthermore, the power assembly includes an electric motor mounted on top of the moving plate, and the electric motor and the rotating shaft are connected by a pulley assembly.

[0022] Furthermore, a suction funnel is installed at the bottom of the rectangular hole, and the bottom of the suction funnel is connected to the vacuum cleaner via a tube.

[0023] In this solution, a vacuum cleaner removes the waste material from the cutting process, preventing the waste from polluting the workshop environment.

[0024] The beneficial effects of this utility model are:

[0025] In the waste edge cutting device for the weaving process provided by this utility model, a movable plate is located in a groove on the top of the mounting platform. Pushing the movable plate along the groove adjusts the cutting distance of the rotating blade on the waste edge, ensuring that the rotating blade can completely cut the fabric waste edge. Positioning bolts are designed on the movable plate to fix it inside the groove, preventing movement during cutting. During cutting, the motor drives the rotating blade to rotate rapidly around the rotation axis. As the fabric passes over the movable plate during rotation, its waste edge is quickly cut, resulting in high waste edge removal efficiency and clean cut fabric edges. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The specific embodiments of the present invention are described below to facilitate understanding by those skilled in the art. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they fall within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0033] like Figure 1 As shown, this embodiment provides a waste edge cutting device for the weaving process. This waste edge cutting device can neatly cut off the waste edges of the fabric, maintaining the aesthetic appearance of the fabric; specifically, it includes:

[0034] Mounting platform 1, moving plate 2, blade assembly 3, and power assembly 4;

[0035] The mounting platform 1 has a sliding plate 2, on which a blade assembly 3 is mounted. The blade assembly 3 is connected to a power unit 4. When the sliding plate 2 is moved along the mounting platform 1, the blade assembly 3 on its top is brought close to the waste edge of the fabric 5. The power unit 4 drives the blade assembly 3 to rotate, cutting off the waste edge of the fabric 5 during rotation, resulting in a neat and consistent edge of the fabric 5.

[0036] The blade assembly 3 includes a shaft holder 31, a rotating shaft 32, and a rotating blade 33. The shaft holder 31 is mounted on a movable plate 2. The rotating shaft 32 is movably connected to a shaft hole at the top of the shaft holder 31, and the rotating blade 33 is connected to the side of the rotating shaft 32 near the waste edge of the fabric 5. A rectangular hole is provided on the movable plate directly below the rotating blade 33, and the edge of the rotating blade 33 is located inside the rectangular hole. The rotating blade 33 rotates rapidly around the rotating shaft 32. As the fabric 5 passes over the movable plate 2 during rotation, its waste edge is quickly cut off, resulting in high waste edge removal efficiency.

[0037] like Figure 2 As shown, a stepped groove is formed on the edge of the rectangular hole near the waste edge of the fabric 5, and a blade rest 34 is placed inside the stepped groove. The two ends of the blade rest 34 are fixed in the stepped groove by two pressing blocks 35. The pressing blocks 35 are installed on the side of the stepped groove by bolts. The blade rest 34 is designed in the rectangular hole so that the waste edge of the fabric 5 is cut by the shearing action of the blade and the blade rest 34, ensuring the sharpness of the blade; at the same time, it avoids the waste edge of the fabric 5 acting on the moving plate 2 during cutting, which would cause severe wear on the edge of the rectangular hole.

[0038] Two pressing rollers 36 are installed on the movable plate 2. The two pressing rollers 36 are distributed on both sides along the long side of the rectangular hole. The two pressing rollers 36 can make the fabric 5 flatter and ensure that the edge of the fabric 5 is laid flat on the movable plate 2 when the rotating blade 33 cuts.

[0039] The pressing roller 36 includes a mounting base 361, which is fixed to the top of the movable plate 2 by bolts; a roller shaft 362 is movably connected to the mounting base 361, and a roller body 363 is connected to the side of the roller shaft 362 near the waste edge of the fabric 5.

[0040] like Figure 3As shown, the top of the mounting platform 1 has a sliding groove, and the movable plate 2 is slidably disposed inside the sliding groove; the top of the movable plate 2 has a threaded hole, and a positioning bolt 21 is disposed in the threaded hole, the positioning bolt 21 passing through the threaded hole and abutting against the bottom of the sliding groove. The movable plate 2 is pushed along the sliding groove until it moves to a position where the rotating blade 33 can just completely cut the waste edge of the fabric 5; after moving, tighten the positioning bolt 21 to fix the movable plate 2 inside the sliding groove and prevent the movable plate 2 from moving during cutting.

[0041] The power assembly 4 includes an electric motor, which is mounted on top of the movable plate 2. The electric motor and the rotating shaft 32 are connected by a pulley assembly.

[0042] A dust collection funnel 61 is installed at the bottom of the rectangular hole, and the bottom of the dust collection funnel 61 is connected to a vacuum cleaner 62 via a pipe. The vacuum cleaner 62 sucks up the waste material cut off, preventing the waste material from polluting the workshop environment.

[0043] In this embodiment, the waste edge cutting device can be installed along the fabric transport path or on the side of the machine tool. When installed along the fabric transport path, the mounting platform 1 is directly fixed to the ground, such as... Figure 4 As shown; when installed on the side of the machine tool, the mounting platform 1 can be directly fixed to the side of the machine tool frame with bolts.

[0044] The working principle of this embodiment is as follows:

[0045] When using the waste edge cutting device for the weaving process provided in this embodiment, loosen the positioning bolt 21 and push the moving plate 2 along the slide groove to adjust the cutting distance of the rotating blade 33 on the waste edge, ensuring that the rotating blade 33 can completely cut the waste edge of the fabric 5. After adjusting the distance, tighten the positioning bolt 21. The positioning bolt 21 can fix the moving plate 2 inside the slide groove to prevent the moving plate 2 from moving during cutting. During cutting, the motor drives the rotating blade 33 to rotate rapidly around the rotating shaft 32. When the fabric 5 passes over the moving plate 2 during rotation, its waste edge is quickly cut off.

[0046] Those skilled in the art will recognize that the embodiments described herein are intended to help the reader understand the principles of this invention, and should be understood that the scope of protection of this invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific modifications and combinations based on these technical teachings disclosed in this invention without departing from the essence of this invention, and these modifications and combinations are still within the scope of protection of this invention.
