Description

Technical Field

[0001] This utility model relates to the field of fabric processing equipment technology, specifically to a fabric cutting machine. Background Technology

[0002] In the production process of textiles, apparel, and home furnishings, it is often necessary to cut rolls of fabric to obtain fabric segments of the required length or shape for subsequent processing.

[0003] Currently, existing fabric cutting machines often encounter several problems when cutting incoming materials. Due to the inherent flexibility and elasticity of fabrics, wrinkles and shifting are common during the cutting process. Traditional cutting machines typically use pressure plates to hold the fabric in place before cutting; however, this method struggles to ensure the fabric remains flat and taut in the cutting area. When the fabric is not flat and taut enough, uneven cut edges and fabric skewing can occur, affecting cutting quality, increasing the difficulty of subsequent processing, and reducing production efficiency. Furthermore, some existing cutting machines fail to effectively limit and tension the fabric in stages, resulting in poor fabric stability during cutting and further impacting the cutting effect. Utility Model Content

[0004] In view of the problems of fabric wrinkling and displacement, poor cutting edge effect, and poor limiting and tensioning effect in the existing fabric cutting machine, this utility model provides a fabric cutting machine to achieve effective limiting and tensioning of the fabric, thereby improving cutting quality and efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fabric cutting machine, including a support, a winding mechanism on the support, a pair of U-shaped brackets on the support, and a tensioning strip on the support. A cylinder is fixed to the inner bottom of the U-shaped brackets. A pair of guide rods are provided between the U-shaped brackets and the support, and guide blocks are slidably connected to the guide rods. The bottom end of the piston rod of the cylinder is fixedly connected to the guide blocks. A rear pressure plate is fixed between the two guide blocks. A pressure groove adapted to the tensioning strip is opened at the bottom of the rear pressure plate. A tensioning strip is fixed on the rear pressure plate. The guide rail has a sliding guide seat that is engaged with the guide rail. A cutting blade is mounted on the guide seat. The support also has a cutting groove adapted to the cutting blade. The two guide blocks are connected to a front pressure plate by a pressing mechanism. The pressing mechanism includes a support block fixed on the guide block. The support block has a guide groove. A guide rod is longitudinally arranged inside the guide groove. A T-shaped guide block is slidably connected to the guide rod. The front pressure plate is fixed between the two T-shaped guide blocks. A spring is sleeved on the guide rod of the T-shaped guide block. When the spring is in its initial state, the lowest point of the front pressure plate is lower than the rear pressure plate.

[0006] Furthermore, the unwinding mechanism includes an unwinding shaft fixed on a support, and the end of the unwinding shaft is provided with a limiting disc for limiting the position of the fabric roll, the limiting disc being threadedly connected to the unwinding shaft.

[0007] Furthermore, the cutting blade is detachably connected to the guide seat by bolts, and the cutting edge of the cutting blade is provided with a wear-resistant coating.

[0008] Furthermore, a rubber pad is provided on the top of the tensioning strip, and the surface of the rubber pad is provided with anti-slip texture.

[0009] Furthermore, a buffer pad is fixed to the bottom of the front pressure plate, and the buffer pad is made of silicone material.

[0010] Furthermore, each of the four bottom corners of the support is provided with an adjusting foot, which includes a screw threaded to the support and a foot pad fixed to the bottom end of the screw.

[0011] Furthermore, a control panel is fixed on the outer wall of the U-shaped bracket, and the control panel is electrically connected to the cylinder.

[0012] When the fabric cutting machine is working, it first installs the rolled fabric on the unwinding shaft of the unwinding mechanism. By adjusting the position of the limiting plate, the fabric roll is limited to prevent axial displacement during the unwinding process.

[0013] When the fabric needs to be cut, the operator starts the cylinder through the control panel. The piston rod of the cylinder begins to extend downward. Since the bottom end of the piston rod of the cylinder is fixedly connected to the guide block, the guide block moves downward under the guidance of the guide rod.

[0014] Because the lowest point of the front pressure plate is lower than the rear pressure plate when the spring is in its initial state, the front pressure plate will first contact the fabric and limit one end of the fabric as the guide block moves downward. As the cylinder piston rod continues to move downward, the guide block continues to drive the rear pressure plate and the pressing mechanism to move downward. At this time, the front pressure plate has pressed down on the fabric, and the T-shaped guide block will slide upward along the guide rod, compressing the spring.

[0015] When the guide block moves to a certain position, the rear pressure plate begins to contact the fabric, limiting the other end of the fabric. During this process, the pressure groove at the bottom of the rear pressure plate cooperates with the tensioning strip on the support. Due to the continuous downward pressure of the rear pressure plate, the tensioning strip is embedded in the pressure groove, so that the fabric to be cut between the front and rear pressure plates is gradually tightened, thereby ensuring that the fabric is in a flat and taut state in the cutting area.

[0016] After the fabric is tensioned and limited, the operator pushes the guide seat, causing it to slide left and right along the guide rail on the rear pressure plate. The cutting blade on the guide seat moves accordingly, engaging with the cutting groove on the support to complete the cutting of the fabric. Because the fabric is in a flat and taut state, the cut edges are neat, resulting in excellent quality.

[0017] After the cutting is completed, the piston rod of the cylinder is retracted by controlling the control panel. The guide block moves upward under the guidance of the guide rod, and the rear pressure plate and the front pressure plate move upward accordingly. The spring returns to its initial state, and the front pressure plate returns to the lowest point, which is lower than the rear pressure plate, waiting for the next cutting operation.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention uses a cylinder to push the guide block downwards. By utilizing the design that the lowest point of the front pressure plate is lower than that of the rear pressure plate, the front pressure plate first limits one end of the fabric. After the cylinder continues to move, the rear pressure plate limits the other end of the fabric. During this process, the tensioning strip and the pressure groove work together to tension and limit the fabric to be cut, effectively preventing wrinkles and displacement of the fabric during the cutting process, ensuring the neatness of the cut edges, and improving the cutting quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figure 1-5 As shown;

[0031] A fabric cutting machine.

[0032] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "Currently, existing fabric cutting machines often encounter problems when cutting incoming materials. Due to the inherent flexibility and elasticity of fabrics, wrinkles and displacement are prone to occur during the cutting process. Traditional cutting machines typically simply press the fabric down with a pressure plate before cutting; however, this method makes it difficult to ensure that the fabric is flat and taut in the cutting area. When the fabric is not flat and taut enough, uneven cut edges and fabric skewing are likely to occur during the cutting process, affecting the cutting quality, increasing the difficulty of subsequent processing, and reducing production efficiency. Moreover, some existing cutting machines cannot effectively achieve step-by-step limiting and tensioning when limiting the fabric, resulting in poor fabric stability during cutting and further affecting the cutting effect." In practical terms, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, a fabric cutting machine is provided.

[0033] like Figure 1-5 As shown in the figure;

[0034] This utility model provides a technical solution: a fabric cutting machine, including a support 1, with adjustable feet provided at the four corners of the bottom of the support 1. Each adjustable foot includes a screw threaded to the support 1 and a foot pad fixed to the bottom of the screw. The height and level of the support 1 can be adjusted by rotating the screw to ensure the stability of the equipment during operation.

[0035] A unwinding mechanism 2 is provided on the support 1. The unwinding mechanism 2 includes an unwinding shaft fixed on the support 1. A limiting plate for limiting the position of the fabric roll is provided at the end of the unwinding shaft. The limiting plate is threadedly connected to the unwinding shaft. After the fabric roll is installed on the unwinding shaft, the limiting plate is rotated to contact the end of the fabric roll, thereby preventing the fabric roll from shifting axially during the unwinding process.

[0036] A pair of U-shaped brackets 3 are installed on the support 1. A control panel is fixed on the outer wall of the U-shaped brackets 3. The control panel is electrically connected to the cylinder 5, which allows the operator to control the movement of the cylinder 5. A pair of guide rods 6 are installed between the U-shaped brackets 3 and the support 1. Guide blocks 7 are slidably connected to the guide rods 6. The cylinder 5 is fixed to the inner bottom of the U-shaped brackets 3. The bottom end of the piston rod of the cylinder 5 is fixedly connected to the guide block 7. When the cylinder 5 is working, it can drive the guide block 7 to slide up and down along the guide rods 6.

[0037] The rear pressure plate 8 is fixed between the two guide blocks 7. The support 1 is also provided with a tensioning strip 4. The top of the tensioning strip 4 is provided with a rubber pad layer. The surface of the rubber pad layer is provided with anti-slip texture. The bottom of the rear pressure plate 8 is provided with a pressure groove 9 that matches the tensioning strip 4. When the rear pressure plate 8 moves downward, the tensioning strip 4 can be embedded in the pressure groove 9. With the rubber pad layer and anti-slip texture, the fabric can be effectively tensioned and limited.

[0038] A guide rail 10 is fixed on the rear pressure plate 8. A sliding guide seat 11 is engaged with the guide rail 10. A cutting blade 12 is mounted on the guide seat 11. The cutting blade 12 is detachably connected to the guide seat 11 by bolts for easy replacement and maintenance. The blade of the cutting blade 12 is coated with a wear-resistant coating to improve its service life. The support 1 also has a cutting groove 13 that matches the cutting blade 12. When the cutting blade 12 slides along the guide rail 10 under the drive of the guide seat 11, it cooperates with the cutting groove 13 to cut the fabric.

[0039] Two guide blocks 7 are connected to a front pressure plate 15 via a pressing mechanism 14. The pressing mechanism 14 includes a support block 141 fixed to the guide blocks 7. A guide groove 142 is provided on the support block 141. A guide rod 143 is longitudinally arranged inside the guide groove 142. A T-shaped guide block 144 is slidably connected to the guide rod 143. The front pressure plate 15 is fixed between the two T-shaped guide blocks 144. A buffer pad is fixed to the bottom of the front pressure plate 15. The buffer pad is made of silicone material and can play a buffering role when limiting the fabric to avoid damaging the fabric. A spring 145 is sleeved on the guide rod 143 of the T-shaped guide block 144. When the spring 145 is in the initial state, the lowest point of the front pressure plate 15 is lower than the rear pressure plate 8.

[0040] The working principle of this embodiment is as follows: In use, the fabric roll is first installed on the unwinding shaft of the unwinding mechanism 2, and the limiting plate is adjusted to limit its position. Then, one end of the fabric is led out from the unwinding mechanism 2 and laid on the support 1, so that the part to be cut is above the tension strip 4 and the cutting groove 13.

[0041] The operator starts cylinder 5 via the control panel. The piston rod of cylinder 5 extends downward, causing guide block 7 to move downward along guide rod 6. Since the lowest point of front pressure plate 15 is lower than rear pressure plate 8 when spring 145 is in its initial state, front pressure plate 15 contacts the fabric first, limiting one end of the fabric.

[0042] Cylinder 5 continues to operate, the piston rod extends further, and guide block 7 continues to move downward. At this time, front pressure plate 15 has pressed down on the fabric, and T-shaped guide block 144 slides upward along guide rod 143, compressing spring 145. Subsequently, rear pressure plate 8 contacts the fabric, limiting the other end of the fabric. At the same time, the pressure groove 9 at the bottom of rear pressure plate 8 cooperates with tensioning strip 4 to tighten the fabric to be cut.

[0043] Afterwards, the operator pushes the guide seat 11 to slide along the guide rail 10, and the cutting blade 12 moves accordingly, cooperating with the cutting groove 13 to complete the cutting of the fabric. After the cutting is completed, the piston rod of the cylinder 5 is controlled to retract through the control panel, the guide block 7 moves upward, and the front pressure plate 15 is reset under the action of the spring 145, waiting for the next operation.

[0044] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
