Description

Technical Field

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

[0002] In the garment manufacturing process, fabric cutting is a crucial step that directly determines the overall quality and appearance of the garment. However, existing fabric cutting equipment has many problems in actual use, resulting in poor fabric cutting quality. Specifically, the fabric cannot be completely secured during the cutting process, which makes it prone to skewing or producing frayed edges. Furthermore, the fabric may be uneven during the cutting process, causing wrinkles to form. This results in uneven force on the cutting blades, affecting the cutting accuracy and leading to fabric that does not meet the required dimensions, thus reducing the quality and efficiency of fabric cutting.

[0003] Therefore, how to design a fabric cutting device that can effectively fix and flatten the fabric, ensuring that the fabric remains flat during the cutting process, thereby improving the cutting quality, has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a fabric cutting device that addresses the problem of poor cutting quality in existing fabric cutting devices mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fabric cutting device, comprising a base, a guide groove on the upper surface of the base, guide rollers fixedly installed at the inlet and outlet of the guide groove, a portal frame on the base, a cutting knife for cutting fabric mounted on the portal frame via a horizontal drive mechanism, and a flattening mechanism mounted on the portal frame, the flattening mechanism comprising a bracket, a bidirectional screw, a stepper motor and two sets of pressing components, the bracket being mounted on the portal frame and perpendicular to the crossbeam of the portal frame, the bidirectional screw being rotatably connected to the bracket, the stepper motor being fixed on the bracket and its output end being drivenly connected to the bidirectional screw, the top ends of the two sets of pressing components being symmetrically threaded to the outer surface of the bidirectional screw and the bottom ends being slidably mounted inside the guide groove via sliders.

[0006] Furthermore, the pressing assembly includes an adjusting frame, which is a rectangular frame. The top of the adjusting frame is threaded to the outer surface of the bidirectional screw, and the bottom two sides are slidably installed inside the guide groove by sliders. An electric push rod is provided on the top inner side of the adjusting frame, and a pressure plate is provided at the output end of the electric push rod. The two side walls of the pressure plate are slidably engaged with the inner side wall of the adjusting frame.

[0007] Furthermore, the bottom end of the pressure plate is provided with a rubber layer to prevent the fabric from slipping.

[0016] like Figures 1 to 3As shown, a fabric cutting device includes a base 1, with a guide groove 2 on the upper surface of the base 1. Guide rollers 3 are fixedly installed at the inlet and outlet of the guide groove 2 on the base 1. A portal frame 4 is provided on the base 1, and a cutting blade 5 for cutting fabric is installed on the portal frame 4 through a horizontal drive mechanism. The device also includes a flattening mechanism on the portal frame 4, which includes a bracket 6, a bidirectional screw 7, a stepper motor 8, and two sets of pressing components. The bracket 6 is fixed on the portal frame 4 and is vertically arranged relative to the crossbeam of the portal frame 4. The bracket 6 and the portal frame 4 are integrally formed. The bidirectional screw 7 is rotatably connected to the bracket 6. The stepper motor 8 is fixed on the bracket 6 and its output end is connected to the bidirectional screw 7 for transmission. The top ends of the two sets of pressing components are symmetrically threaded to the outer surface of the bidirectional screw 7, and the bottom ends are slidably installed inside the guide groove 2 through sliders. The guide rollers 3 can guide the fabric smoothly into the guide groove 2, avoiding fabric deviation in the initial stage. Since the tops of the two sets of clamping components are symmetrically threaded onto the bidirectional screw 7 via mounting bases, when the bidirectional screw 7 rotates, the two sets of clamping components will move in opposite directions along the screw.

[0017] The pressing assembly includes an adjusting frame 9, which is a rectangular frame. The top of the adjusting frame 9 is threaded to the outer surface of the bidirectional screw 7, and the bottom two sides are slidably installed inside the guide groove 2 by sliders. An electric push rod 10 is provided on the top inner side of the adjusting frame 9. A pressure plate 11 is provided at the output end of the electric push rod 10. The two side walls of the pressure plate 11 are slidably engaged with the inner side wall of the adjusting frame 9.

[0018] The bottom of the pressure plate 11 is provided with a rubber layer to prevent the fabric from sliding, and the rubber layer increases the friction.

[0019] The upper surface of the base 1 is provided with a cutting groove 12, which is used in conjunction with the cutting blade 5.

[0020] The horizontal drive mechanism includes a lead screw 13 rotatably disposed inside the portal frame 4 and a motor 14 fixedly installed on the outside of the portal frame 4. The output end of the motor 14 passes through the portal frame 4 and is fixedly connected to the lead screw 13. A slider 15 is threadedly connected to the lead screw 13. A cutter 5 is fixedly installed at the bottom of the slider 15. A guide rod 16 is fixedly installed inside the portal frame 4. The guide rod 16 passes through the slider 15 and is slidably connected to the slider 15.

[0021] The specific operation process of this utility model is as follows:

[0022] Connect an external power source to provide the necessary power for the equipment to operate. Place the fabric to be cut in the guide groove 2 and ensure that the fabric passes through the guide roller 3 from the bottom. Both ends of the guide roller 3 are equipped with retaining rings to restrict the fabric in the guide groove 2. The fabric is laid flat on the upper surface of the base 1 along the guide groove 2, ensuring that the fabric covers the cutting groove 12 flat. Align the cutting position with the running trajectory of the cutter 5 to prepare for subsequent cutting.

[0023] The start motor drives the guide roller 3 to convey the fabric forward. When the fabric is conveyed to the cutting area, the guide roller 3 stops, the electric push rod 10 starts, and pushes the pressure plate 11 to move downward. The rubber layer at the bottom of the pressure plate 11 contacts the fabric and applies pressure. The rubber layer increases friction to prevent the fabric from sliding during the cutting process. The start stepper motor 8 drives the bidirectional screw 7 to rotate. At this time, the two sets of pressing components press the fabric on both sides through the synchronous adjustment of the bidirectional screw 7. At the same time, the transmission of the bidirectional screw 7 makes the fabric evenly tensioned, eliminating wrinkles on the fabric surface and ensuring that the fabric remains flat in the cutting area. The tension of the fabric can be adjusted as needed to ensure a more perfect cutting effect, that is, both pressing components pull the fabric away from the cutter 5.

[0024] Next, the horizontal drive mechanism is activated, and the motor 14 drives the lead screw 13 to rotate. The thread on the lead screw 13 causes the slider 15 to move in a straight line under the drive of the lead screw 13 for precise cutting. After the cutting is completed, the two guide rollers 3 are activated. The guide roller 3 near the outlet of the guide groove 2 can transport the cut fabric to the outlet of the guide groove 2, and the other guide roller 3 can continue to transport the remaining fabric to the cutting area, that is, the position of the cutter 5. After adjusting the position, the next cutting can begin.
