[0001] This utility model relates to the field of fabric cutting technology, and more specifically, it relates to a cutting device for high-elastic decorative fabrics. Background Technology

[0002] Decorative fabrics can be categorized by material, including pure cotton, cotton-polyester blends, pure polyester, wool-polyester blends, and pure wool. These fabrics can be printed and dyed in various colors, or printed or woven into various patterns to suit the needs of different environments.

[0003] Currently, decorative fabrics are typically cut manually by laying the fabric flat on a processing table and then cutting it using a cutting device. After cutting, the fabric is then manually removed, which is laborious and reduces processing efficiency.

[0004] Therefore, a solution needs to be proposed to address this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a high-elasticity decorative fabric cutting device. By setting an unwinding roller, the fabric is lowered into a clamping groove, and then the fabric is clamped by moving two clamping rollers, which facilitates the cutting blade to cut the fabric. The cut fabric will fall into a collection groove by itself, making collection more convenient and improving cutting efficiency.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] A high-elastic decorative fabric cutting device, such as Figures 1-2 As shown, the device includes a main body, which includes a support 1 and an unwinding roller 2 rotatably connected to the support 1. A clamping roller 3 rotatably connected to the support 1 is located directly below the unwinding roller 2. A base 5 is located on one side of the support 1. A vertical rod 6 is slidably connected to the upper end face of the base 5. A clamping roller 4 is rotatably connected to the side of the vertical rod 6 near the vertical rod 6. A clamping groove 8 for the fabric to pass through is formed between the clamping roller 4 and the clamping roller 3. A collection box 7 is located below the clamping groove 8.

[0022] The upper end face of the base 5 is provided with a receiving groove 10, and a movable rod 11 is slidably connected to it in the receiving groove 10. The vertical rod 6 is fixedly connected to one end of the movable rod 11. The upper end face of the movable rod 11 is provided with a plurality of arrayed teeth 12. The upper end face of the base 5 is fixedly connected with a mounting plate. A gear 13 that meshes with the teeth 12 is rotatably connected to the mounting plate. A motor 1 for driving the gear 13 to rotate is mounted on the mounting plate. The motor 1 is a servo motor. The output shaft of the motor 1 is connected to the gear 13 for transmission. A limit rod 18 is fixedly connected to the inner wall of the receiving groove 10. A through groove for the limit rod 18 to pass through is provided on the movable rod 11.

[0023] As the moving rod 11 moves along with the rotation of the gear 13, the moving rod 11 will rotate along the limiting rod 18, making the moving rod 11 more stable during the movement.

[0024] A cutting blade 9 is slidably connected to the side wall of the vertical rod 6. A driving device is provided on the vertical rod 6 to drive the cutting blade 9 to move. When the clamping roller 2 4 and clamping roller 1 3 clamp the fabric, the cutting blade 9 can just make contact with the fabric to cut.

[0025] The driving device includes a groove 14 on the side wall of the vertical rod 6. A lead screw 15 is rotatably connected to the inner wall of the groove 14. A second motor, a servo motor, is installed on the outer wall of the vertical rod 6 to drive the lead screw 15 to rotate. One end of the lead screw 15 is connected to the output shaft of the servo motor. A nut seat 16 is sleeved on the lead screw 15. A driving rod 17 is fixedly connected to the side wall of the nut seat 16. The cutting blade 9 is fixedly connected to the end of the driving rod 17 away from the nut seat 16. A limit block 19 is fixedly connected to the side wall of the nut seat 16. A limit groove 20 is provided on the inner wall of the groove 14 for the limit block 19 to be inserted and moved.

[0026] As the nut seat 16 moves with the rotation of the lead screw 15, the limiting block 19 will be inserted into the limiting groove 20 and move, making the nut seat 16 more stable during the movement.

[0027] Working principle: When decorative fabric needs to be cut into multiple segments, firstly, rotate the unwind roller 2 so that the starting end of the fabric naturally falls into the clamping groove 8. When the unwind reaches the required cutting length, the motor drives the gear 13 to rotate. Since the gear 13 meshes with the clamping teeth 12 on the moving rod 11, the rotation of the gear 13 drives the moving rod 11 to move. The moving rod 11 then moves the vertical rod 6 closer to the support 1. The clamping roller 4 and the cutting blade 9 on the vertical rod 6 also move closer to the falling fabric until the fabric is clamped between the clamping roller 4 and the clamping roller 3. At this time, the cutting blade 9 will also be in contact with the fabric. Then, turn off the motor and the vertical rod 6 will stop at its current position.

[0028] Then, the second motor drives the lead screw 15 to rotate, which in turn drives the nut seat 16 to rotate. The nut seat 16 then drives the cutting blade 9 to move via the driving rod 17, cutting the fabric horizontally. Then, the first motor drives the gear 13 to rotate in the opposite direction, which in turn drives the moving rod 11 to move in the opposite direction via the clamping teeth 12. The clamping roller 4 and the cutting blade 9 on the vertical rod 6 move away from the bracket 1, releasing the fabric. The cut fabric falls from the clamping groove 8 into the collecting groove, completing the collection. Meanwhile, the unwinding roller 2 continues to unwind, allowing the next section of fabric to be cut to fall into the clamping groove 8, waiting for the clamping roller 4 to clamp and the cutting blade 9 to cut. This cycle repeats, achieving the cutting and collection of the fabric. The operation is convenient and improves the cutting efficiency of the fabric.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
