[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A silk fabric cutting device includes a cutting frame 1, one end of which is rotatably connected to a feeding roller 2. During cutting, the fabric roll can be placed onto the feeding roller 2 for convenient feeding. Four leveling rollers 3 are rotatably connected to the inner side of the cutting frame 1. The fabric is inserted into the four leveling rollers 3 for tensioning and leveling. The four leveling rollers 3 are grouped in pairs, with the fabric between the two leveling rollers 3 in the same group forming an S-shape for leveling and tensioning, ensuring the fabric is taut before passing through the cutting shears 7. The top of the cutting frame 1... A U-shaped support rod 4 is fixedly connected, which conveniently supports the cutting scissors 7, allowing them to cut the fabric from above. The number of cutting scissors 7 can be increased according to the fabric cutting requirements. When not in use, they can be moved directly to the edge of the support rod 4 to prevent interference with fabric cutting. A sliding sleeve 5 is slidably connected to the surface of the support rod 4. When the position of the cutting scissors 7 needs to be adjusted according to the required fabric width, the position of the cutting scissors 7 can be easily adjusted by sliding the sliding sleeve 5 on the support rod 4, thus meeting the needs of different fabric cutting widths and enabling better fabric cutting. The cutting scissors 7 are mounted on the surface of the sliding sleeve 5 via a mounting mechanism 6, which stably fixes the cutting scissors 7 onto the sliding sleeve 5. Four flattening rollers 3 are located on both sides of the cutting scissors 7. Before cutting, the flattening rollers 3 are used to flatten and tension the fabric, and after cutting, the flattening rollers 3 are also used to flatten and tension the fabric to ensure that the fabric remains flat throughout the cutting process, preventing any impact on the cutting effect. A screw is threadedly connected to the top of the sliding sleeve 5. 8. When the sliding sleeve 5 moves to the position where the fabric needs to be cut, the screw 8 can be rotated. The screw 8 squeezes the support rod 4 to stabilize the position of the sliding sleeve 5, thereby stabilizing the position of the cutting scissors 7 to cut the fabric and ensure the cutting effect. The top of the cutting frame 1 is rotatably connected to the take-up roller 9. The take-up roller 9 can take up the cut fabric. When taking up the fabric, the motor drives the take-up roller 9 to move, thereby causing the take-up roller 9 to pull the fabric on the feed roller 2 to move, thus facilitating the take-up.

[0024] Furthermore, the mounting mechanism 6 includes a mounting groove 601 formed on the surface of the sliding sleeve 5. An insertion block 602 is fixedly connected to the top of the cutting shears 7. The insertion block 602 is located inside the mounting groove 601. A U-shaped fastening block 603 is rotatably connected to the surface of the screw 8. When the fabric needs to be cut, the cutting shears 7 needs to be fixed on the sliding sleeve 5 first. During this process, the insertion block 602 needs to be placed inside the mounting groove 601. Then, the fastening block 603 is lowered by the rotation of the screw 8 to restrict the insertion block 602, ensuring the stability of the insertion block 602. This allows the cutting shears 7 to cut the fabric stably.

[0025] Furthermore, a stabilizing groove 604 is provided at the bottom of the mounting groove 601. A stabilizing ball 606 is elastically connected to the bottom of the stabilizing groove 604 via a compression spring 605. A force-receiving groove 607 is provided on the surface of the insertion block 602. One end of the fastening block 603 is located inside the force-receiving groove 607. When the insertion block 602 is inserted into the mounting groove 601, the stabilizing ball 606 is subjected to the elastic force of the compression spring 605, causing a portion of the stabilizing ball 606 to enter the force-receiving groove 607, thus preventing the insertion block 602 from moving horizontally. At the same time, the fastening block 603 compresses the insertion block 602, and one end of the fastening block 603 is stuck inside the force-receiving groove 607, thereby preventing the insertion block 602 from shaking inside the mounting groove 601. The insertion block 602 is stably fixed by the cooperation of the stabilizing ball 606 and the fastening block 603, ensuring that the insertion block 602 will not shake during use and guaranteeing the stability of the cutting scissors 7 in cutting the fabric.

[0026] Furthermore, a pressure plate 608 is rotatably connected to the bottom of the screw 8, and a friction plate 609 is fixedly connected to the top of the support rod 4. When it is necessary to stabilize the sliding sleeve 5, the pressure plate 608 can be lowered by rotating the screw 8 to press against the friction plate 609, thereby increasing the friction between the pressure plate 608 and the friction plate 609, so that the sliding sleeve 5 will not slip, ensuring the stability of the cutting shears 7 and enabling the cutting of fabric to meet the required width.

[0027] Furthermore, the top of the sliding sleeve 5 is provided with an auxiliary groove 610. The interior of the auxiliary groove 610 is elastically connected to the bottom of the fastening block 603 through a pop-out spring 611. During the rotation of the screw 8, the fastening block 603 is subjected to the elastic force of the pop-out spring 611, so that the fastening block 603 will not wobble after the screw 8 rotates, which enables the fastening block 603 to be used stably and ensures the restriction of the insertion block 602.

[0028] Furthermore, two flat blocks 10 are fixedly connected to the surface of the cutting scissors 7. When the cutting scissors 7 cuts the fabric, the fabric is restricted by the flat blocks 10 to ensure that the fabric is in a horizontal position during cutting when it is pulled by the take-up roller 9, so that the fabric can be cut better.

[0029] In summary:

[0030] During cutting, the sliding sleeve 5 needs to be slid on the surface of the support rod 4 first, so that the sliding sleeve 5 moves to a position that meets the cutting requirements of the fabric. Then, the insertion block 602 is sent into the installation groove 601 so that the cutting shears 7 are connected to the sliding sleeve 5. After the insertion block 602 enters the installation groove 601, part of the stabilizing ball 606 enters the force groove 607 through the elastic force of the compression spring 605 inside the stabilizing groove 604. With one end of the fastening block 603 stuck in the force groove 607, the insertion block 602 is stably fixed inside the installation groove 601. When the screw 8 rotates, it drives the fastening block 603 to fall off. During this process, the fastening block 603 is subjected to the elastic force of the pop-out spring 611 inside the auxiliary groove 610, which can ensure that the fastening block 603 will not wobble on the screw 8. The fastening block 603 stably restricts the force groove 607, so that the insertion block 602 can be more stably fixed on the sliding sleeve 5. During rotation, the rod 8 can press the friction plate 609 by lowering the pressure plate 608, thereby improving the stability of the sliding sleeve 5 and ensuring that the sliding sleeve 5 can be stably fixed on the support rod 4. This ensures the stability of the cutting scissors 7, allowing them to stably cut the fabric. Afterward, the fabric is pulled and wound around the take-up roller 9. The motor is started to make the take-up roller 9 rotate, which pulls the fabric on the feed roller 2, making the fabric flat and taut. During the cutting process, the flattening block 10 can keep the fabric flat when it is being cut. With the above structure, when it is necessary to cut silk fabric, the position of the cutting scissors 7 can be easily adjusted according to the needs, so that the fabric can be cut to different widths to meet the needs of different fabrics. Furthermore, the cutting scissors 7 will not wobble or misalign during the cutting process, ensuring that the cutting scissors 7 can cut the fabric stably.
