Abstract
Description
Technical Field
[0001] This utility model belongs to the field of garment processing technology, specifically relating to a fabric cutting machine for PU garment processing. Background Technology
[0002] In the processing of PU garments, the fabric cutting machine is the core equipment for cutting fabric. Its main function is to precisely cut the roll of PU fabric according to the design dimensions, providing qualified cut pieces for subsequent sewing processes. Currently, fabric cutting machines for PU garment processing on the market typically include a worktable, a cutting device mounted on the worktable, and a fabric winding device for conveying the fabric. Some machines will add a simple fabric pressing structure between the cutting device and the fabric winding device to reduce fabric displacement during cutting.
[0003] Existing fabric cutting machines for PU garment processing are inadequate because PU fabrics are highly elastic and have a smooth surface. Traditional pressing structures often use rigid downward pressure, which cannot achieve dynamic tensioning of the fabric. Before cutting, the fabric must be smoothed and the tension adjusted manually, which is not only time-consuming but also prone to wrinkles and displacement due to human error, ultimately leading to dimensional deviations in the cut. Furthermore, cutting PU fabric in a non-tensioned state is prone to burrs and snags, severely affecting the quality of the cut pieces. The pressing action of traditional fabric cutting machines often requires manual triggering, and the operator must simultaneously ensure the fabric alignment and start the pressing action, resulting in a heavy load on both hands and easy operational errors due to fatigue. In addition, some machines lack an automatic reset structure, requiring manual repositioning of the pressing components after each pressing action, further extending the single cutting cycle time and making them unsuitable for batch processing. Utility Model Content
[0004] The purpose of this utility model is to provide a fabric cutting machine for PU garment processing, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A fabric cutting machine for PU garment processing includes a worktable. The surface of the workbench is provided with a cutting device, and the rear of the workbench is provided with a fabric rolling device. Two support columns are symmetrically arranged on both sides of the workbench and between the cutting device and the fabric rolling device. A fabric pressing mechanism is provided between the two support columns. An operating groove is opened inside one of the support columns, and a drive component is provided inside the operating groove. The fabric pressing mechanism includes a light rod, which is rotatably installed between two support columns and located above the worktable. A fixed fabric plate is movably provided on the surface of the light rod. Swing rods are fixedly installed at both ends of the light rod, and a crossbar is fixedly connected to the top of the swing rod. A fabric pressing plate is installed at the top of the crossbar through a rotating shaft. The drive assembly includes a gear, with the optical rod fixedly connected to the center of the gear. A movable rod is provided on the side of the gear, and a rack is provided at the top of the movable rod to mesh with the gear.
[0006] In a preferred embodiment of this utility model, the interior of the optical rod is provided with a movable groove, and a first spring is provided inside the movable groove. A connecting post is connected to the top of the first spring, and the top of the connecting post is fixedly connected to the fixed fabric plate. The fixed fabric plate movably covers the surface of the optical rod, and the end of the fixed fabric plate is set to be arc-shaped.
[0007] In a preferred embodiment of this utility model, the end of the pressing plate is arc-shaped, and a tension spring is connected between the top of the crossbar and the bottom surface of the pressing plate.
[0008] As a preferred embodiment of this utility model, a limiting strip is provided at the top of the crossbar, and the pressing plate is in an inclined state when it contacts the limiting strip.
[0009] As a preferred embodiment of this utility model, a bottom strip is fixedly provided at the bottom end of the movable rod, a sliding groove is provided on the side of the bottom strip, and a protruding strip is provided at the bottom end inside the operating groove, and the sliding groove is slidably sleeved on the surface of the protruding strip.
[0010] As a preferred embodiment of this utility model, a second spring is provided at the bottom of the operating groove, and the top of the second spring is fixedly connected to the bottom strip.
[0011] As a preferred embodiment of this utility model, a foot pedal is provided at one end of the bottom strip near the cutting device, and the surface of the foot pedal is provided with anti-slip texture.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the synergistic action of the fixed fabric plate and the pressing fabric plate, the fixed fabric plate acts as an anchor point to prevent the fabric from sliding, and the pressing fabric plate simultaneously tensions the fabric when it is pushed forward, which can flatly press the PU fabric onto the workbench surface, avoiding the offset of the cut caused by fabric wrinkles and displacement during cutting. Cutting under tension can effectively reduce the phenomena of burrs, snags and uneven melting of PU fabric, directly improving the cutting quality. The foot pedal drive design allows the operator to focus on laying and aligning the fabric with both hands, and only needs to step on the foot to start the pressing fabric process, realizing an efficient operation mode of using both hands and feet, greatly shortening the cutting preparation time and reducing the time spent on process changeover.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0018] Example Reference Figure 1-4 This is an embodiment of the present invention, which provides a fabric cutting machine for PU garment processing, including a worktable 1. A cutting device 2 is provided on the surface of the workbench 1, and a cloth rolling device is provided behind the workbench 1. Two support columns 3 are symmetrically arranged on both sides of the workbench 1 and between the cutting device 2 and the cloth rolling device. A cloth pressing mechanism 4 is provided between the two support columns 3. An operating groove is opened inside one of the support columns 3, and a drive component is provided inside the operating groove. The pressing mechanism 4 includes a straight rod 5, which is rotatably installed between two support columns 3 and is located above the worktable 1. A fixed cloth plate 14 is movably provided on the surface of the straight rod 5. Swing rods 6 are fixedly installed at both ends of the straight rod 5. A crossbar 7 is fixedly connected to the top of the swing rod 6. A pressing plate 8 is installed at the top of the crossbar 7 through a rotating shaft. The drive assembly includes a gear 15, with a light rod 5 fixedly connected to the center of the gear 15. A movable rod 16 is provided on the side of the gear 15, and a rack is provided at the top of the movable rod 16 to mesh with the gear 15.
[0019] During use, as the movable rod 16 descends, the rack at its top moves downwards. Since the rack meshes with the gear 15, the linear motion of the rack is converted into the rotational motion of the gear 15. This rotation of the gear 15 causes the guide rod 5 to rotate as well. Swing rods 6 are fixedly mounted at both ends of the guide rod 5. When the guide rod 5 rotates, it causes the two swing rods 6 to swing forward synchronously. Since the crossbar 7 and the pressure plate 8 are connected to the top of the swing rods 6, when the swing rods 6 swing downwards and backwards, they cause the pressure plate 8 to move downwards. Upon contact with the fabric, its lower edge adheres tightly to the fabric surface due to friction. As the entire mechanism swings forward, it generates a forward thrust on the fabric. Eventually, the end of the pressure plate 8 presses onto the fabric in front of the cutting device 2. Simultaneously, as the guide rod 5 rotates, the fixed fabric plate 14 also rotates synchronously. When the pressure plate 8 pushes the fabric forward, the fixed fabric plate 14 acts as an anchor point, preventing the fabric from sliding forward. Under the combined action of the fixed fabric plate 14 and the pressure plate 8, the fabric located between the two is tensioned and flatly pressed onto the worktable 1, awaiting cutting by the cutting device 2.
[0020] In summary, under the action of the drive component and the pressing mechanism 4, the pressing plate 8 can iron out any wrinkles that may exist in the fabric by pressing down and pushing forward, eliminating the need for manual smoothing and tightening of the fabric, which greatly shortens the preparation time for each cut and thus improves the overall processing efficiency. In particular, for chemical fiber fabrics such as PU, cutting under tension can effectively prevent the appearance of rough edges, fraying, or uneven melting at the cut.
[0021] Furthermore, the interior of the light rod 5 is provided with a movable groove 11, and a first spring 12 is provided inside the movable groove 11. The top end of the first spring 12 is connected to a connecting post 13, and the top end of the connecting post 13 is fixedly connected to a fixed cloth plate 14. The fixed cloth plate 14 movably covers the surface of the light rod 5, and the end of the fixed cloth plate 14 is set to be arc-shaped.
[0022] In use, when not in operation, the first spring 12 is in a naturally extended or slightly compressed state, supporting the fixed fabric plate 14 at a default height through the connecting column 13. When the light rod 5 starts to rotate, it drives the entire fixed fabric plate 14 mechanism to swing forward and downward, so that the arc-shaped end of the fixed fabric plate 14 contacts the fabric surface. During the process of the fixed fabric plate 14 continuing to press down, if it encounters uneven fabric thickness, slight unevenness on the worktable 1 surface, or protrusions such as seams in the fabric itself, the fixed fabric plate 14 will be subjected to an upward reaction force. This structure can automatically adapt to changes in the thickness of the fabric itself, or uneven edges during multi-layer cutting.
[0023] Furthermore, the end of the pressing plate 8 is set to be arc-shaped, and a tension spring 9 is connected between the top of the crossbar 7 and the bottom surface of the pressing plate 8. A limit strip 10 is provided at the top of the crossbar 7. When the pressing plate 8 contacts the limit strip 10, the pressing plate 8 is in an inclined state.
[0024] During use, when the pressure plate 8 is not in contact with the fabric, under the tension of the tension spring 9, the top of the pressure plate 8 will lean back against the limiting strip 10. At this time, the pressure plate 8 is fixed in a preset inclined state. When the drive assembly is activated, the swing rod 6 drives the crossbar 7 and the pressure plate 8 to swing downward and forward. The pressure plate 8 first contacts the fabric surface with its arc-shaped end. Because the pressure plate 8 is inclined and the bottom is arc-shaped, this structure allows it to cut into the fabric surface very smoothly, effectively preventing the fabric from being pushed forward and wrinkled. During the process of the pressure plate 8 contacting the fabric and continuing to push forward, the tension spring 9 plays a key role. It provides a continuous, flexible downward pull to ensure that the pressure plate 8 is in close contact with the fabric surface.
[0025] Furthermore, a bottom strip 17 is fixedly provided at the bottom end of the movable rod 16. A sliding groove is provided on the side of the bottom strip 17. A protruding strip is provided at the bottom end of the operating groove. The sliding groove is slidably fitted on the surface of the protruding strip. A second spring 18 is provided at the bottom end of the operating groove. The top of the second spring 18 is fixedly connected to the bottom strip 17. A foot pedal is provided at the end of the bottom strip 17 near the cutting device 2. The surface of the foot pedal is provided with anti-slip texture.
[0026] In use, the bottom end of the movable rod 16 is fixed to the bottom strip 17. The sliding groove on the side of the bottom strip 17 slides onto the protruding strip at the bottom end of the operating groove. This structure forms a precise guide rail. When the movable rod 16 moves, it can only move vertically up and down in the direction specified by the protruding strip without shaking or rotating, ensuring the stability of the drive assembly during operation. The second spring 18 is set at the bottom end of the operating groove, and its top abuts against the bottom strip 17. When the movable rod 16 moves downward, the bottom strip 17 compresses the second spring 18. After the downward force disappears, the compressed second spring 18 pushes the bottom strip 17 upward, thereby causing the entire movable rod 16 to automatically return to its original position, preparing for the next fabric pressing cycle. The foot pedal provides the operator with a way to manually trigger or control the operation in an emergency. The operator can step on the foot pedal, which drives the bottom strip 17 to overcome the elasticity of the second spring 18 and force the movable rod 16 to descend, thereby manually starting the fabric pressing process. The anti-slip texture on the surface of the foot pedal ensures that the foot will not slip when stepping on it, making the operation safe and reliable.
[0027] In summary, the operator's hands can be fully focused on laying, aligning, and organizing the fabric. Once the fabric is in place, the operator can simply step on the foot pedal to start the pressing and tensioning process, achieving a highly efficient operation mode that combines hands and feet. This significantly saves process changeover time and improves work efficiency.
