Technical Field

[0001] This utility model relates to a cutting device, and more particularly to a cutting device for patchwork fabrics, belonging to the field of fabric cutting technology. Background Technology

[0002] As a traditional handicraft, patchwork has been widely used in clothing, home decoration, and other fields in recent years. Cutting patchwork fabric is a crucial step in the production process of patchwork crafts, and its precision and efficiency directly affect the subsequent sewing and the overall quality of the finished product.

[0003] The "Fabric Cutting Device" disclosed in application number "202322212907.1" "includes a side plate and a dust collection component. The inner walls of the side plate are embedded with the worktable on both sides. The upper surface of the worktable has drainage holes on both sides. The lower end of the side plate is fixedly connected to the dust collection component. The upper surface of the side plate is fixedly connected to the slide rail. The inner wall of the slide rail is movably connected to the sliding component. The outer wall of the sliding component is connected through the sliding table. The lower end of the sliding table is fixedly connected to the cutting tool." In this utility model, the cutting tool is moved laterally by a sliding rod on the inner wall of the slide rail. The sliding rod is movably connected through the sliding table by a sliding groove, which facilitates the longitudinal movement of the cutting tool. This makes it easier to adjust the angle of the fabric for cutting and improves the accuracy and efficiency of fabric cutting.

[0004] However, the above method still has the following drawbacks: While the cutting accuracy and efficiency of the fabric can be improved by moving the cutting blade longitudinally, in the actual process of cutting the fabric, given that the fabric itself is soft, it is difficult to fix it firmly during the cutting operation. This can easily cause the fabric to shift during the cutting process, which in turn has an adverse effect on the cutting accuracy of the fabric. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for patchwork fabrics to solve the problems mentioned in the background art, such as the fabric being soft and difficult to fix, easily shifting during cutting, and affecting cutting accuracy.

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.

[0025] Please see Figure 1-6 This utility model provides a cutting device for patchwork fabric, including a workbench 1. A support 2 is slidably mounted inside the workbench 1. A cutting blade 3 is mounted inside the support 2 to facilitate cutting the fabric 16. Fixed frames 4 are mounted on the top of both sides of the support 2. A rotating frame 5 is mounted in the middle of the bottom of the fixed frame 4. A rotating rod 6 is rotatably mounted in the middle of the rotating frame 5. A gear 7 is fixedly mounted in the middle of the rotating rod 6. An adjusting component 11 for adjusting the gear 7 is located at the bottom of the fixed frame 4. The rotation of the gear 7 drives... The rotating rod 6 and the first support arm 8 rotate synchronously, which can drive the first support arm 8 and the second support arm 9 to swing, thereby allowing the pressure plate 10 to move in the vertical direction. This allows the pressure plate 10 to press and fix the fabric, thus preventing displacement during cutting and ensuring the accuracy of the fabric during the cutting process. The surface of the rotating rod 6 is fixedly equipped with the first support arm 8, and the bottom end of the first support arm 8 is rotatably equipped with the second support arm 9. The bottom end of the second support arm 9 is rotatably equipped with the pressure plate 10, and the bottom end of the pressure plate 10 is equipped with an anti-slip pad for anti-slip purposes.

[0026] The adjusting assembly 11 includes a rack plate 1101, which is slidably disposed at the bottom of the fixed frame 4. The bottom of the fixed frame 4 has a limiting groove for movement of the rack plate 1101, and limiting plates are provided on both sides of the rack plate 1101. A gear 7 meshes with the rack plate 1101. A moving rod 1102 is provided on one side of the rack plate 1101, and a horizontal plate 1103 is provided at the top of one side of the support 2. An electric push rod 1104 is fixedly disposed at the top of the horizontal plate 1103. A moving plate 1105 is provided on the telescopic rod of the electric push rod 1104. One end of the moving rod 1102 is fixedly connected to one side of the moving plate 1105. The adjusting assembly 11 also includes two guide blocks 1106, which are respectively fixedly installed on the fixed frame 4. At the bottom of both sides, a guide rod 1107 is slidably provided inside the guide block 1106, and the bottom end of the guide rod 1107 is fixedly connected to the top end of the pressure plate 10. The shortening of the telescopic rod of the electric push rod 1104 drives the moving plate 1105, the two moving rods 1102, and the two rack plates 1101 to move in the horizontal direction. The movement of the rack plates 1101 drives the gear 7 to rotate, which in turn drives the rotating rod 6 and the first support arm 8 to rotate synchronously. Combined with the guide rod 1107, the second support arm 9 swings, which in turn drives the pressure plate 10 to move in the vertical direction, which facilitates the pressing and fixing of the fabric 16 at the workbench 1, avoids the fabric from shifting during the cutting process, and improves the accuracy of subsequent fabric cutting.

[0027] The bottom of the workbench 1 is provided with a moving assembly 12 for moving the support 2. The moving assembly 12 includes two support plates 1201, which are fixedly installed on both sides of the bottom of the workbench 1. A lead screw 1202 is rotatably provided between the two support plates 1201. The lead screw 1202 is threadedly set at the bottom of the support 2 through a lead screw nut. The moving assembly 12 also includes a forward and reverse motor 1203. The forward and reverse motor 1203 is fixedly installed on one side of one of the support plates 1201, and the output shaft of the forward and reverse motor 1203 passes through the support plate 1201 and is fixedly connected to one end of the lead screw 1202. Through the moving assembly 12, the forward and reverse motor 1203 is controlled to drive the lead screw 1202 to rotate in the forward and reverse directions. Combined with the lead screw nut, the support 2 can be moved in the horizontal direction, which facilitates the position adjustment of the cutting blade 3 and improves the flexibility when cutting the fabric 16.

[0028] The workbench 1 has a sliding groove 20 that slides with the support 2 inside, and a sliding rod 21 is provided inside the sliding groove 20. The bottom of the support 2 has a guide hole that slides with the sliding rod 21. The sliding groove 20 and the sliding rod 21 provide a limiting and guiding function when the support 2 moves in the horizontal direction.

[0029] A hydraulic cylinder 13 is provided at the middle of the top of the support 2. The telescopic rod of the hydraulic cylinder 13 passes through the support 2 and is fixedly connected to the middle of the top of the cutter 3. By extending the hydraulic rod of the hydraulic cylinder 13, the cutter 3 is driven to move in the vertical direction, so as to cut the fabric at the workbench 1.

[0030] Two mounting plates 14 are symmetrically arranged on one side of the workbench 1. A winding rod 15 is slidably arranged in the middle of the two mounting plates 14. Fabric 16 is wound around the surface of the winding rod 15. A screw 17 is threadedly connected to the middle of the mounting plate 14. A knob 18 is provided at the top of the screw 17. A moving groove 19 is provided on one side of the mounting plate 14 for moving the winding rod 15. This facilitates the use of the screw 17 to pick up and put in the mounting plate 14, limits the winding rod 15, and facilitates the disassembly of the winding rod 15 and the fabric 16, making it convenient to replace the fabric 16.

[0031] In use, first, place the fabric 16, wound up to the take-up rod 15, onto the two mounting plates 14. The take-up rod 15 is placed inside the moving groove 19 on the mounting plate 14, allowing it to rotate. Next, insert the screw 17 into the mounting plate 14 and rotate it using the knob 18, causing the screw 17 to block and limit the take-up rod 15. Then, stretch the fabric 16 and lay it on the worktable 1. As needed, cut the fabric 16. Control the forward and reverse rotation motor 1203 to drive the lead screw 1202 to rotate forward or in the reverse direction. Combined with the lead screw nut, this causes the bracket 2 to move along the slide groove 20, thereby adjusting the position of the cutter 3 for easy cutting. After cutting fabric pieces 16 of different sizes and determining their positions, the extension rod of the electric push rod 1104 is shortened, which drives the two moving rods 1102 and the two rack plates 1101 to move smoothly in the horizontal direction. Since the rack plate 1101 is meshed with the gear 7, it drives the rotating rod 6 and the first support arm 8 to rotate synchronously. Combined with the guiding action of the guide rod 1107, the second support arm 9 swings accordingly, which causes the pressure plate 10 to move in the vertical direction, effectively pressing the fabric 16 on the worktable 1 firmly. Then, the hydraulic cylinder 13 is controlled to drive the cutting blade 3 to move downward, so that the fabric 16 can be cut. This ensures that the fabric 16 will not shift during the cutting process, which greatly improves the accuracy of subsequent fabric cutting.
