Description

Technical Field

[0001] This utility model relates to the field of fabric cutting equipment technology, specifically to a trimming device for home textile fabrics. Background Technology

[0002] In the home textile production process, the edges of fabrics need to be trimmed and adjusted to meet specified dimensions and neatness. Trimming equipment is often used and plays a key role in the production of home textile products such as bed sheets, duvet covers, and curtains.

[0003] Trimming equipment generally includes a frame, a conveying mechanism, trimming cutters, and a drive mechanism. After the fabric is transported to the cutting table, due to the fabric's certain toughness, the clamping parts need to press the fabric tightly during positioning and cutting. However, uneven clamping force can easily cause the fabric to become crooked and wrinkled, which is inconvenient to adjust. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing edge-cutting devices apply uneven pressure when clamping and fixing the fabric, which affects the accuracy of the cut.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: The present utility model proposes a cutting device for home textile fabrics, including a cutting table, two sets of guide rails are arranged in the length direction on the cutting table, a movable frame slides on the guide rails, a ball screw module is installed on the guide rails, a linear motor module is arranged at the bottom of the movable frame, a laser cutting head is installed on the moving end of the linear motor module, and pressing components for positioning and adjusting the fabric are arranged on both sides of the cutting table.

[0006] Preferred technical solution 1: The pressing assembly includes a C-shaped support frame mounted on a cutting table. Guide grooves are provided on both sides of the support frame, and a lifting platform slides up and down within these guide grooves. An electric telescopic rod is provided on the top of the support frame, and its free end is connected to the lifting platform. A drive cavity is provided within the lifting platform, and a through groove is formed at the bottom of the drive cavity. A screw support block is provided within the drive cavity, and a drive screw rotates between the screw support block and the inner wall of the drive cavity. A drive motor is provided on one side of the screw support block, and the motor's power output shaft is connected to the drive screw. Two sets of threads with opposite directions are provided on the drive screw. An upper pressure plate slides at the bottom of the lifting platform. Slider blocks are threadedly connected to each of the two sets of threads, and the bottom of the sliders passes through the through groove and connects to the upper pressure plate.

[0007] Preferred technical solution 2: Positioning grooves are provided at the four corners of the cutting table, and the positions of the positioning grooves correspond to the upper pressure plate. Guide slide rods are provided on both sides of the positioning groove. A lower pressure plate also slides in the positioning groove and slides through the guide slide rod. A buffer spring is sleeved on the guide slide rod, and the two ends of the buffer spring abut against the side wall of the lower pressure plate and the side wall of the positioning groove, respectively.

[0008] Preferred technical solution 3: Mounting frames are provided on both sides of the cutting table. A winding roller is rotatably mounted on one set of mounting frames, and a winding motor is also provided on the mounting frame, with the power output shaft of the winding motor connected to the winding roller. A mounting groove is provided on the other set of mounting frames, and a fabric roller is detachably placed in the mounting groove. A locking block is also hinged on the mounting frame, and a waist-shaped hole is provided at the other end of the locking block. A threaded hole is provided at the corresponding position on the mounting frame. By passing a bolt through the waist-shaped hole and engaging with the threaded hole, the locking block can be locked and fixed to the mounting frame.

[0009] Preferred technical solution four: The side wall of the cutting table is equipped with a controller, and the ball screw module, linear motor module, drive motor, electric telescopic rod and winding motor are all electrically connected to the controller. The controller is also connected to an operation panel and a touch screen.

[0010] Preferred technical solution five: The opposing surfaces of the upper pressure plate and the lower pressure plate are covered with a rubber anti-slip layer.

[0011] The edge-cutting device for home textile fabrics proposed in this utility model has the following beneficial effects achieved by adopting the above structure:

[0012] (1) The sliding blocks of two sets of reverse threaded groups are driven by the drive screw in the pressing assembly, and the lifting platform is lifted and lowered in conjunction with the electric telescopic rod, so as to achieve uniform pressing of the home textile fabric by the upper and lower pressure plates, avoiding fabric wrinkles or displacement caused by uneven local force. At the same time, the high-precision transmission of the ball screw module and the linear motor module further ensures the accuracy of the laser cutting head's motion trajectory and greatly improves the accuracy of edge cutting.

[0013] (2) The detachable fabric roller design, combined with the quick-fixing structure of the locking block, facilitates the quick replacement and installation of the fabric; the take-up roller automatically takes up the cut fabric under the drive of the take-up motor. Combined with the controller's automated control of each component and the parameter setting functions of the operation panel and touch screen, manual intervention is reduced, and the continuity and convenience of the overall operation are improved.

[0014] (3) The rubber anti-slip layer set on the opposite surfaces of the upper and lower pressure plates can increase the friction between the upper and lower pressure plates and the fabric, prevent the fabric from sliding during the cutting process, and avoid damage to the fabric caused by the hard pressure plate. The elastic buffer design of the lower pressure plate with the buffer spring can adapt to the pressing requirements of fabrics of different widths and improve the equipment's adaptability to different types of fabrics.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagrams, while the terms “inner” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] Example 1

[0024] like Figures 1-4As shown, the technical solution adopted by this utility model is as follows: A cutting device for home textile fabrics includes a cutting table 1, two sets of guide rails 2 are arranged in the length direction on the cutting table 1, a movable frame 3 slides on the guide rails 2, and a ball screw module is installed on the guide rails 2 to drive the movable frame 3 to move. The ball screw module drives the ball screw to rotate through a motor. The rotational motion is converted into linear motion of the nut driving the movable frame 3 by the rolling of the balls between the screw and the nut. The parallel guide rails ensure the accuracy and stability of the motion. A linear motor module is set at the bottom of the movable frame 3. A laser cutting head is installed on the moving end of the linear motor module. The linear motor module consists of a stator, a mover, a linear guide rail, and a position feedback device. Based on the principle of electromagnetic induction, the stator generates a magnetic field. After current is passed through the coil of the mover, an electromagnetic force is generated, which directly drives the mover to make linear motion without the need for an intermediate conversion mechanism. Both the linear motor module and the ball screw module are relatively mature existing technologies and will not be described in detail. Pressing components for positioning and adjusting the fabric are set on both sides of the cutting table 1. The pressing assembly includes a C-shaped support frame 4 mounted on a cutting table 1. Guide grooves are provided on both sides of the support frame 4, and a lifting platform 5 slides up and down within the guide grooves. An electric telescopic rod is provided on the top of the support frame 4, and the free end of the electric telescopic rod is connected to the lifting platform 5. A drive cavity is provided inside the lifting platform 5, and a through groove 6 is provided at the bottom of the drive cavity. A screw support block 7 is provided inside the drive cavity, and a drive screw 8 rotates between the screw support block 7 and the inner side wall of the drive cavity. A drive motor 9 is provided on one side of the screw support block 7, and the power output shaft of the motor is connected to the drive screw 8. Two sets of threads with opposite directions are provided on the drive screw 8. An upper pressure plate 10 also slides on the bottom of the lifting platform 5. A slider 11 is threadedly connected to each of the two sets of threads, and the bottom of the slider 11 passes through the through groove 6 and is connected to the upper pressure plate 10.

[0025] Example 2

[0026] Based on Example 1, such as Figure 3 and Figure 4 As shown, positioning grooves 12 are provided at the four corners of the cutting table 1. The positions of the positioning grooves 12 correspond to the upper pressure plate. Guide slide rods 13 are provided on the two inner side walls of the positioning grooves 12. A lower pressure plate 14 also slides in the positioning grooves 12 and slides through the guide slide rods 13. A buffer spring 15 is sleeved on the guide slide rod 13, and the two ends of the buffer spring 15 abut against the side wall of the lower pressure plate 14 and the side wall of the positioning groove 12, respectively. The spring constant of the buffer spring 15 is 50-100N / m. Through the cooperation of the upper pressure plate 10 and the lower pressure plate 14, the four corners of the fabric can be dragged to ensure uniform pressing force and avoid fabric wrinkles. A rubber anti-slip layer is pasted on the opposite surfaces of the upper pressure plate 10 and the lower pressure plate 14. The thickness of the rubber layer is 3-5mm.

[0027] like Figure 4As shown, mounting frames 16 are provided on both sides of the cutting table 1. A take-up roller 17 is rotatably mounted on one set of mounting frames 16 for winding the cut fabric. A take-up motor 18 is also provided on the mounting frame 16, and the power output shaft of the take-up motor 18 is connected to the take-up roller 17. A mounting groove 19 is provided on the other set of mounting frames 16, and a fabric roller 20 is detachably placed in the mounting groove 19. A locking block 21 is also hinged on the mounting frame 16. The other end of the locking block 21 is provided with a waist-shaped hole, and a threaded hole is provided at the corresponding position on the mounting frame 16. By passing a bolt through the waist-shaped hole and engaging with the threaded hole, the locking block 21 can be locked and fixed to the mounting frame 16, thereby limiting the position of the installed fabric roller 20 and facilitating fabric replacement.

[0028] The cutting table 1 is equipped with a controller 22 on its side wall. The ball screw module, linear motor module, drive motor 9, electric telescopic rod and winding motor 18 are all electrically connected to the controller 22. The controller 22 is also connected to an operation panel and a touch screen, which can realize the automated control and parameter setting of each component.

[0029] Specific usage methods of fabric cutting equipment

[0030] Fabric roller installation: First, open the locking block 21 on the mounting bracket 16 on one side of the cutting table 1, unscrew the bolts to rotate the locking block 21 around the hinge, and place the fabric roller 20 into the mounting slot 19. Then, reset the locking block 21, and lock it in place by passing the bolt through the slotted hole and engaging with the threaded hole on the mounting bracket 16. This completes the limiting installation of the fabric roller 20, ensuring that the fabric can be released smoothly. Check the take-up roller 17 on the other side of the mounting bracket 16 to ensure that the take-up motor 18 is securely connected to the take-up roller 17 and that there are no foreign objects on the surface of the take-up roller 17, ensuring smooth subsequent take-up operations.

[0031] Turn on the controller 22 and confirm through the operation panel or touch screen that the ball screw module, linear motor module, drive motor 9, electric telescopic rod and winding motor 18 are all in power-on standby state and the parameter setting interface is displayed normally.

[0032] Initial fabric laying: Pull out one end of the fabric from the fabric roller 20 and lay it flat on the surface of the cutting table 1, ensuring that the fabric covers the cutting area and that the edges are roughly aligned with the length of the cutting table 1. Fix the free end of the fabric to the take-up roller 17, and drive the take-up motor 18 to rotate slightly through the controller 22 to keep the fabric in an initial tension state.

[0033] The operating controller 22 controls the extension of the electric telescopic rod, causing the lifting platform 5 to descend along the guide groove of the C-shaped support frame 4. This causes the upper pressure plate 10 to press down until it contacts the lower pressure plate 14 in the four corner positioning grooves 12 of the cutting table 1. The four corners of the fabric are clamped between the upper pressure plate 10 and the lower pressure plate 14. The drive motor 9 is started, driving the drive screw 8 to rotate. Since the two sets of threads on the drive screw 8 are in opposite directions, the slider 11 will move in opposite directions along the through groove 6, thereby causing the two sets of upper pressure plates 10 to open or close synchronously, adjusting to correspond to the positions of the four corners of the fabric. At this time, the lower pressure plate 14 slides slightly along the guide slide bar 13, while the rubber anti-slip layer increases friction to prevent the fabric from wrinkling or sliding.

[0034] Input cutting dimensions, path and other parameters through the touch screen of controller 22, set the movement speed of ball screw module and linear motor module, power of laser cutting head and other parameters, and save the settings after confirming the parameters.

[0035] After cutting, the winding motor 18 drives the winding roller 17 to rotate, wrapping the cut fabric around the winding roller 17. The winding speed matches the operating rhythm of the equipment to avoid fabric accumulation or pulling.
