Description

Technical Field

[0001] This utility model relates to the technical field of fabric cutting equipment, and in particular to a fabric cutting equipment. Background Technology

[0002] After the fabric is processed, it needs to be sampled or cut. The existing fabric cutting method generally uses scissors for manual cutting, which is slow and the cuts are uneven and prone to slant. The precision is not high. Therefore, a cutting machine is needed to cut the fabric.

[0003] An existing fabric cutting device (publication number: CN222700704U) has at least the following drawbacks: Before cutting the fabric, the device requires the fabric to hang on one side of the cutting blade, and then press the fabric to cut. Since the device does not have a tensioning mechanism to tighten the fabric, the fabric may produce certain ripples or wrinkles when it hangs naturally, which makes it impossible to completely eliminate these undulations when pressing it later, thus affecting the straightness and dimensional accuracy of the cut edge. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fabric cutting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fabric cutting device includes a cutting frame. The cutting frame has a cutting component for cutting fabric inside. The cutting component includes a fixed frame fixed inside the cutting frame. Two upper clamps are slidably arranged inside the fixed frame. A cutter frame is fixed inside the cutting frame below the fixed frame. A cutting blade and a cutting seat are slidably arranged inside the cutter frame. A drag frame is slidably arranged inside the cutting frame below the cutter frame. Two lower clamps are slidably arranged inside the drag frame. The bottom surface of the upper clamp and the top surface of the lower clamp are both provided with misalignment openings. The misalignment openings of the upper clamp and the lower clamp are misaligned and adapted to each other.

[0006] As a further embodiment of this utility model, a drive screw is rotatably connected to one side of the cutting frame, and the other side of the drag frame is threadedly connected to the outer wall of the drive screw. A first motor is also fixed to one side of the cutting frame, and the output shaft of the first motor is fixed to the top end of the drive screw.

[0007] As a further embodiment of this utility model, a bidirectional lead screw is rotatably connected to one side of the fixed frame, the cutter frame, and the drag frame. The two upper clamps, the cutter and the cutter seat, and the two lower clamps are respectively threaded to the outer wall of the three bidirectional lead screws. A second motor is fixed to the front side of the fixed frame, the cutter frame, and the drag frame. The output shaft of the second motor is fixed to the front end of the bidirectional lead screw.

[0008] As a further embodiment of this utility model, an unwinding roller is rotatably connected inside the cutting frame near the top surface, and a third motor is fixed on one side of the cutting frame, with the output shaft of the third motor fixed to one end of the unwinding roller.

[0009] As a further embodiment of this utility model, the unwinding roller consists of a roller body and a mounting base, and the roller body and the mounting base are detachably mounted by flanges and bolts.

[0010] As a further embodiment of this utility model, a receiving box is placed on the inner top surface of the cutting frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The upper clamp holds one end of the fabric, and then the driving frame moves to the fixed frame, so that the lower clamp overlaps with the upper clamp and the lower clamp holds one end of the fabric. The upper clamp then releases. The driving frame moves down a certain distance according to the required cutting length of the fabric. Then the upper clamp holds the fabric again, and the lower clamp moves to a distance equal to the height of the cutting seat between the upper clamp and the lower clamp. The lower clamp also holds the fabric and pulls it down to straighten the fabric. Then the cutting blade cuts the fabric along the lower edge of the upper clamp to complete the cutting process. During the cutting process, the fabric can be effectively positioned and straightened to prevent the fabric from being too loose and producing ripples or wrinkles, which would affect the straightness and dimensional accuracy of the cut edge.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figures 1-4 As shown, a fabric cutting device includes a cutting frame 1. The cutting frame 1 is equipped with a cutting component for cutting fabric. The cutting component includes a fixing frame 2 fixed inside the cutting frame 1. Two upper clamps 201 are slidably arranged inside the fixing frame 2. A cutter frame 202 is fixed inside the cutting frame 1 below the fixing frame 2. A cutting blade 203 and a cutting seat 204 are slidably arranged inside the cutter frame 1 below the cutter frame 202. A drag frame 205 is slidably arranged inside the drag frame 205 below the cutter frame 202. Two lower clamps 206 are slidably arranged inside the drag frame 205. The bottom surface of the upper clamp 201 and the top surface of the lower clamp 206 are both provided with misalignment openings. The misalignment openings of the upper clamp 201 and the lower clamp 206 are misaligned and adapted to each other.

[0018] like Figures 2-4As shown, in this embodiment, a drive screw 3 is rotatably connected to one side of the cutting frame 1, and a drag frame 205 is threadedly connected to the outer wall of the drive screw 3 on one side. A first motor is also fixed to one side of the cutting frame 1, and the output shaft of the first motor is fixed to the top end of the drive screw 3. By pulling one end of the fabric and placing it at the upper clamp 201, the two upper clamps 201 are driven to move closer to each other to clamp one end of the fabric. Then, the first motor is started to drive the drive screw 3 to rotate, thereby driving the drag frame 205, which is threadedly connected to the drive screw 3, to move to the bottom of the fixed frame 2, so that the lower clamp 206 and the upper clamp 201 are matched, and the lower clamp 206 and the upper clamp 201 overlap. Then, the two lower clamps 206 clamp one end of the fabric, and at this time, the upper clamp 201 releases the fabric. Then, according to the required cut length of the fabric, the drive frame 205 moves down a certain distance. At this time, the upper clamp 201 clamps the fabric again. Then, the lower clamp 206 moves to a distance of the height of the cutting seat 204 from the upper clamp 201. The lower clamp 206 also clamps the fabric and moves down slightly, pulling the fabric to make it straight. Then, the cutter 203 and the cutting seat 204 are driven to move closer to each other and cut the fabric along the lower edge of the upper clamp 201 to complete the cutting process. Then, the lower clamp 206 releases the cut fabric, and the lower clamp 206 continues to overlap with the upper clamp 201 to clamp the fabric and drag it for cutting. During the cutting process, the fabric can be effectively positioned and straightened to prevent the fabric from being too loose and producing ripples or wrinkles, which would affect the straightness and dimensional accuracy of the cut edge.

[0019] like Figures 2-4 As shown in this embodiment, the fixed frame 2, the cutter holder 202, and the drag frame 205 are all rotatably connected to one side of a bidirectional lead screw 207. The two upper clamps 201, the cutter 203 and the cutter seat 204, and the two lower clamps 206 are respectively threaded to the outer wall of the three bidirectional lead screws 207. The front side of the fixed frame 2, the cutter holder 202, and the drag frame 205 are all fixed with a second motor. The output shaft of the second motor is fixed to the front end of the bidirectional lead screw 207. By starting the second motor, the bidirectional lead screw 207 is rotated, which causes the two upper clamps 201, the cutter 203 and the cutter seat 204, and the two lower clamps 206 that are threaded to the bidirectional lead screw 207 to move closer to each other and clamp and cut the fabric.

[0020] like Figures 2-4 As shown in this embodiment, the inside of the cutting frame 1 is rotatably connected to the unwinding roller 4 near the top surface. A third motor is fixed on one side of the cutting frame 1. The output shaft of the third motor is fixed to one end of the unwinding roller 4. By starting the third motor, the unwinding roller 4 can be driven to rotate slowly and release the fabric, ensuring that the fabric is released at a uniform and slow speed.

[0021] like Figures 2-4As shown, in this embodiment, the unwinding roller 4 is composed of a roller body 401 and a mounting base 402. The roller body 401 and the mounting base 402 are detachably installed by a flange and bolts. By setting the roller body 401 and the mounting base 402 to be detachably installed by a flange and bolts, it is convenient to replace the roller body 401 after the fabric on the roller body 401 has been cut.

[0022] like Figures 2-4 As shown in this embodiment, a receiving box 5 is placed on the inner top surface of the cutting frame 1. By setting up the receiving box 5, the cut fabric can be collected in a centralized manner.

[0023] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when it is necessary to cut the fabric, the roller 401 is detachably installed to the mounting base 402 by bolts. Then, one end of the fabric is pulled up and placed at the upper clamp 201. During this process, the third motor drives the unwinding roller 4 to rotate slowly and release the fabric. Then, the second motor is started to drive the bidirectional lead screw 207 to rotate, causing the two upper clamps 201 threaded to the bidirectional lead screw 207 to move closer to each other and clamp one end of the fabric. Then, the first motor is started to drive the drive lead screw 3 to rotate, thereby driving the drag frame 205 threaded to the drive lead screw 3 to move to the bottom of the fixed frame 2, so that the lower clamp 206 and the upper clamp 201 are matched and overlapped. Then, the second motor is started to drive the lower clamp 206 to clamp one end of the fabric. When the upper clamp 201 releases the fabric, the driving frame 205 moves down a certain distance according to the required cutting length of the fabric. At this time, the upper clamp 201 clamps the fabric again. Then, the lower clamp 206 moves to a distance of the height of the cutting seat 204 from the upper clamp 201. The lower clamp 206 also clamps the fabric and moves down slightly, pulling the fabric to make it straight. Then, the second motor is started to drive the cutting blade 203 and the cutting seat 204 to move closer to each other and cut the fabric along the lower edge of the upper clamp 201 to complete the cutting process. Then, the lower clamp 206 releases the cut fabric, allowing the fabric to fall into the collection box 5 for centralized collection. The lower clamp 206 continues to overlap with the upper clamp 201 to clamp the fabric and drag it for cutting. During the cutting process, the fabric can be effectively positioned and straightened to prevent the fabric from being too loose during cutting, causing ripples or wrinkles, which would affect the straightness and dimensional accuracy of the cutting edge.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
