Description

Technical Field

[0001] The utility model relates to the technical field of clothing manufacturing, in particular to an automatic cutting device for fabrics used in clothing manufacturing. Background Art

[0002] In the clothing manufacturing process, fabrics are indispensable raw materials. After production, fabrics are usually stored in whole rolls, with relatively large widths and lengths. For subsequent processing, the bundled fabrics need to be cut in the middle first, divided into two halves or smaller segments, so as to facilitate subsequent processes such as cutting and sewing, making the entire production process smoother and more efficient.

[0003] There are many types of fabrics used in clothing manufacturing, including cotton, linen, silk, chemical fiber, leather and other materials. The physical properties (such as thickness, hardness, elasticity, etc.) and cutting requirements of each material are also different. This requires the cutting device to be able to flexibly handle fabrics of different thicknesses to ensure cutting quality and efficiency. Moreover, during the fabric segmentation process, as the fabric is continuously wound up, the diameter of the winding wheel gradually increases, resulting in a decrease in the fit between the cutting tool and the fabric, which may lead to insufficient fabric cutting. Summary of the Invention

[0004] To solve the above problems, the present application provides an automatic cutting device for fabrics used in clothing manufacturing, which is provided with a frame. A fabric winding mechanism and a fabric roller are arranged on the frame. A fabric cutting mechanism is arranged on one side of the fabric winding mechanism. The fabric cutting mechanism is provided with a cutting support frame. A cutting lifting unit is arranged on the cutting support frame. A cutter support frame is arranged on the cutting lifting unit. A cutting tool is arranged on the cutter support frame.

[0005] In one embodiment, tool rotation drivers and tool clamping drivers are respectively arranged on both sides of the cutter support frame. A rotating disk is arranged at the output end of the tool rotation driver. A clamping disk is rotatably arranged at the output end of the tool clamping driver.

[0006] In one embodiment, the fabric winding mechanism includes a winding support frame. A winding motor is arranged on the winding support frame. The winding motor is connected to the winding roller through a coupling. A winding cutting groove is arranged on the winding roller.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application 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 only used to explain the present application and are not used to limit the present application.

[0028] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0029] As Figures 1-4 shown, an automatic cutting device for fabric used in clothing manufacturing is provided with a frame 1. A fabric winding mechanism 2 and a fabric roller 3 are arranged on the frame 1. A fabric cutting mechanism 4 is arranged on one side of the fabric winding mechanism 2. The fabric cutting mechanism 4 is provided with a cutting support frame 41. A cutting lifting unit 42 is arranged on the cutting support frame 41. A cutter support frame 43 is arranged on the cutting lifting unit 42. A cutting tool 44 is arranged on the cutter support frame 43.

[0030] Specifically, the fabric winding mechanism 2 is used to wind and roll up the fabric on the fabric roller 3. The fabric on the fabric roller 3 is the fabric to be cut. The fabric cutting mechanism 4 is used to precisely cut the fabric during the fabric winding process. The cutting support frame 41 is stably installed on the frame 1. The cutting lifting unit 42 automatically adjusts its height according to the winding progress of the fabric to ensure a constant degree of fit between the cutting tool 44 and the fabric. When the equipment is running, the fabric on the fabric roller 3 is fed onto the fabric winding mechanism 2, and the fabric winding mechanism 2 starts to work, winding and rolling up the fabric. As the fabric is wound, the diameter of the fabric winding wheel gradually increases. The cutting lifting unit 42 controls the height of the cutting tool 44 according to the change in the diameter of the winding wheel to ensure the degree of fit between the cutting tool 44 and the fabric. Through the automatic adjustment function of the cutting lifting unit 42, it can ensure a constant degree of fit between the cutting tool 44 and the fabric, achieve precise cutting, and avoid the problem of inaccurate cutting caused by the increase in the diameter of the winding wheel. This device can process fabrics of different materials and different thicknesses. By adjusting the parameters of the cutting lifting unit 42, it can easily adapt to the cutting requirements of different fabrics. In addition, precise cutting results in better flatness and consistency of the cutting edge, which helps to improve the overall quality of the product.

[0031] As Figure 2 shown, on both sides of the cutter support frame 43, there are respectively arranged a tool rotation drive 45 and a tool clamping drive 46. The output end of the tool rotation drive 45 is provided with a rotating disk 451, and the output end of the tool clamping drive 46 is rotatably provided with a clamping disk 461.

[0032] Specifically, the tool rotation drive 45 is a servo motor, and the tool clamping drive 46 is a cylinder. The output end of the tool clamping drive 46 is rotatably provided with a clamping disk 461. When the cutting tool 44 needs to be installed, the clamping drive 46 drives the clamping disk 461 to move towards the rotating disk 451 side, clamping the cutting tool 44 between the rotating disk 451 and the clamping disk 461. The output end of the tool rotation drive 45 is connected to the rotating disk 451. When the tool rotation drive 45 is started, the rotating disk 451 drives the cutting tool 44 to rotate, realizing dynamic cutting. The rotating cutting method helps to reduce the cutting resistance, making the cutting smoother, and also helps to improve the flatness and precision of the cutting surface. In addition, by setting the clamping disk 461, the replacement of the cutting tool 44 becomes simple and fast, without a complex disassembly process.

[0033] As Figure 3 shown, the fabric winding mechanism 2 includes a winding support frame 21. On the winding support frame 21, there is arranged a winding motor 22. The winding motor 22 is connected to the winding roller 23 through a coupling. The winding roller 23 is provided with a winding cutting groove 24.

[0034] Specifically, when the rewinding motor 22 rotates, its power is transmitted to the winding roller 23 through a coupling, causing the winding roller 23 to start rotating. As the winding roller 23 rotates, the fabric is gradually wound around the winding roller 23, achieving the rewinding of the fabric. The rotation of the winding roller 23 provides a stable winding center for the fabric, enabling the fabric to be wound orderly. A winding cutting groove 24 is provided on the winding roller 23 to accurately position the fabric to be cut.

[0035] As Figure 4 shown, the cutting lifting unit 42 includes a cutting lifting motor 421, the cutting lifting motor 421 is connected to a lead screw 422, a lifting slider 423 is provided on the lead screw 422, and a cutter support frame 43 is fixedly installed on the lifting slider 423.

[0036] Specifically, the output shaft of the cutting lifting motor 421 is connected to the lead screw 422. As the cutting lifting motor 421 rotates, power is transmitted to the lead screw 422, and the lead screw 422 starts to rotate. When the lead screw 422 rotates, due to the meshing effect of the threads, the lifting slider 423 moves up and down along the length direction of the lead screw 422. Since the cutter support frame 43 is fixedly installed on the lifting slider 423, when the lifting slider 423 moves, the cutter support frame 43 also moves up and down accordingly. By controlling the rotation speed of the cutting lifting motor 421, the moving speed of the cutter support frame 43 can be accurately controlled, thereby achieving precise cutting.

[0037] As Figure 4 shown, there are two cutting lifting units 42, which are respectively located on both sides of the cutter support frame 43 and are both connected to the cutter support frame 43.

[0038] Specifically, arranging the cutting lifting units 42 on both sides can provide more stable support. When the cutter support frame 43 and the cutting tool 44 thereon are lifting, the two cutting lifting units 42 can jointly share the weight and load, reducing the shaking or tilting caused by uneven force on one side, thereby improving the stability of the entire cutting system. The design of the bilateral cutting lifting units 42 helps to achieve the dynamic balance of the cutter support frame 43 during the lifting process. By precisely controlling the synchronous movement of the two cutting lifting units 42, the cutting accuracy and efficiency are guaranteed. Moreover, when dealing with thick or large-sized fabrics, the two lifting units can jointly provide greater lifting force and support force.

The cutting lifting unit 42 automatically adjusts the height according to the winding progress of the fabric to ensure a constant degree of fit between the cutting tool 44 and the fabric. When the device is running, the fabric on the fabric roller 3 is fed onto the fabric winding mechanism 2, and the fabric winding mechanism 2 starts to work, winding and rolling up the fabric. As the fabric is wound up, the diameter of the fabric winding wheel gradually increases. The cutting lifting unit 42 controls the height of the cutting tool 44 according to the change in the diameter of the winding wheel to ensure the degree of fit between the cutting tool 44 and the fabric.
