Description

Technical Field

[0001] This invention relates to the field of fabric cutting technology, and more specifically, to a fabric cutting device for garment production. Background Technology

[0002] In garment manufacturing, fabric laying and cutting are crucial steps before sewing. Laying rolls of fabric flat on the cutting table and cutting them is an important part of the garment assembly line. The quality and efficiency of fabric laying and cutting directly affect the subsequent sewing processes and the overall economic benefits of the garment manufacturing company.

[0003] As the garment industry continues to demand higher production efficiency and quality, fabric cutting equipment is also constantly evolving. Currently, various automated cutting machines are available on the market, such as fabric cutting machines using vibrating blade cutting heads and high-speed fabric laying cutting machines equipped with fabric spreading mechanisms. Some machines are also equipped with positioning components to position the cutting area and prevent wrinkles from forming in the fabric during the cutting process; others use a structure with upper and lower cutting blades working together to improve cutting quality. Furthermore, some fabric laying machines can now achieve double-layer fabric laying, completing the laying of two layers of fabric in a single reciprocating motion by using double-layer fabric clamps; other solutions achieve double-layer fabric laying by using a double unwinding frame in conjunction with a fabric merging component.

[0004] However, all the existing fabric cutting equipment mentioned above shares a common fundamental limitation in their operating modes: all of them operate on a single-sided fabric laying mode. Whether it's a traditional fabric laying machine using a back-and-forth fabric clamp, an improved solution using double-layer fabric clamps to achieve double-layer laying, or an alternative solution using a double unwinding rack to achieve double-layer laying, the fabric laying method involves stacking and laying the fabric on a single plane of the cutting table. After the fabric is laid, cutting can only be performed on the upper surface of the fabric stack; that is, a single cutting action can only process the fabric laid on one side of the cutting table, and the cutting efficiency is limited by the number of fabric surfaces. When a large amount of fabric needs to be cut, it can only be achieved by increasing the number of fabric layers or repeating the laying and cutting process multiple times, which is difficult to meet the ever-increasing demands for production efficiency.

[0005] To address the aforementioned issues, the market needs a fabric cutting device that can overcome the limitations of the single-sided fabric laying operation mode and improve fabric cutting efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a fabric cutting device for garment production that can overcome the limitations of the single-sided fabric laying operation mode and improve fabric cutting efficiency.

[0007] The embodiments of the present invention are implemented as follows: This application provides a fabric cutting device for garment production, including: frame; A fabric laying board is rotatably mounted on the frame. The fabric laying board has a first laying surface and a second laying surface for supporting fabric. The first laying surface and the second laying surface are arranged opposite each other and are located on both sides of the thickness direction of the fabric laying board. The end of the fabric laying board is provided with a fastener for fixing the end of the fabric to the fabric laying board. The fabric supply assembly includes a fabric roll roller wound with fabric to be cut into rolls. The fabric roll roller is rotatably mounted on the frame and located on the outer side of one end of the fabric laying plate. The rotation axis of the fabric roll roller is parallel to the rotation center line of the fabric laying plate, and the two ends of the fabric roll roller along its axial direction are aligned with the two sides of the fabric laying plate along its width direction. The end pressing assembly includes a clamp for pressing the end of the fabric against the end of the fabric board, the clamp being fixedly mounted on the frame; The fabric cutting assembly includes two cutting mechanisms, both of which are mounted on the frame and located on the same side as the first and second fabric surfaces of the fabric laying board. The two cutting mechanisms are used to cut the fabric that is stacked layer by layer on the first and second fabric surfaces.

[0008] In some embodiments of the present invention, the above-mentioned fastener includes a telescopic member and a clamping member. The end of the fabric panel is provided with a strip groove along the width direction. The clamping member is a pressing strip adapted to the strip groove. The telescopic member is disposed on both sides of the fabric panel, and the telescopic end of the telescopic member is connected to the pressing strip to drive the pressing strip to move along the depth direction of the strip groove so as to press and fix the end of the fabric extending into the strip groove.

[0009] In some embodiments of the present invention, the clamping device includes a gripper and a telescopic device, the telescopic device being disposed on the frame, and the telescopic end of the telescopic device extending and retracting along a radial direction passing through the rotation center of the fabric board, and the gripper being disposed at the telescopic end of the telescopic device.

[0010] In some embodiments of the present invention, the two cutting mechanisms are symmetrically arranged on both sides of the diameter where the clamp is located, and the two cutting mechanisms are centrally symmetrical about the rotation center line of the fabric board.

[0011] In some embodiments of the present invention, each of the above-mentioned cutting mechanisms includes a three-axis slide module and a cutting tool. The three-axis slide module is disposed on the frame, and the cutting tool is disposed at the moving end of the three-axis slide module. The three moving axes of the three-axis slide module are respectively arranged along the width direction, length direction and thickness direction of the fabric laying board.

[0012] In some embodiments of the present invention, the cutting tool described above is any one of a vibrating knife, a laser cutting head, or a disc knife.

[0013] In some embodiments of the present invention, the above-mentioned fabric rolling roller includes a cylinder and a rotating shaft. The cylinder is disposed on the rotating shaft, the rotating shaft is rotatably disposed on the frame, and a damping element is disposed between the rotating shaft and the frame to dampen the rotation of the rotating shaft and the frame.

[0014] In some embodiments of the present invention, a rotating mechanism is provided between the fabric panel and the frame. The rotating mechanism includes two rotating frames, which are symmetrically fixed on both sides of the fabric panel along its width direction. The two rotating frames are coaxially rotatably mounted on the frame via the same central axis. A driving mechanism is connected to any one of the rotating frames. The driving mechanism is used to drive the rotating frame to rotate around the central axis, thereby causing the fabric panel to flip around its rotation center line.

[0015] In some embodiments of the present invention, the fabric slab is provided with limiting plates on both sides along its width direction. The limiting plates extend along the length direction of the fabric slab and protrude from the surface of the fabric slab to constrain the position of the fabric in the width direction.

[0016] In some embodiments of the present invention, the above-mentioned fabric supply assembly further includes a guide roller, which is rotatably disposed on the frame and located between the fabric roll roller and the fabric laying plate. The axis of the guide roller is parallel to the axis of the fabric roll roller. After the fabric is drawn out from the fabric roll roller, it passes through the guide roller and enters the surface of the fabric laying plate.

It rotates a fabric laying plate onto a frame, creating a first and second fabric laying surface positioned opposite each other. Two cutting mechanisms are located on opposite sides of the two fabric laying surfaces. During the plate's rotation, the fabric is simultaneously laid onto both surfaces. A complete laying cycle creates a fabric stack on both surfaces. After laying, the two cutting mechanisms simultaneously cut the fabric on both surfaces. Compared to existing devices that can only cut fabric stacks on a single plane, this invention overcomes the limitations of single-sided laying operations, doubling the fabric throughput within the same laying and cutting time, thus significantly improving cutting efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] Example Please refer to Figures 1-5This application provides a fabric cutting device for garment production, including a frame 1, a fabric laying plate 2, a fabric supply assembly, an end pressing assembly, and a fabric cutting assembly. The fabric laying plate 2 is rotatably mounted on the frame 1. The fabric laying plate 2 has a first laying surface 3 and a second laying surface 4 for supporting the fabric. The first laying surface 3 and the second laying surface 4 are arranged opposite each other and are located on opposite sides of the fabric laying plate 2 in the thickness direction. A fastener 5 is provided at the end of the fabric laying plate 2 for fixing the fabric end to the fabric laying plate 2. The fabric supply assembly includes a fabric rolling roller 6 wound with the fabric to be cut into rolls. The fabric rolling roller 6 is rotatably mounted on the frame 1 and located on the outer side of one end of the fabric laying plate 2. The rotation axis of the fabric rolling roller 6 is parallel to the rotation center line of the fabric laying plate 2, and the two ends of the fabric rolling roller 6 along its axial direction are aligned with the two sides of the fabric laying plate 2 along its width direction. The end-pressing assembly includes a clamp 7 for pressing the fabric end against the end of the fabric laying plate 2, and the clamp 7 is fixedly mounted on the frame 1. The fabric cutting assembly includes two cutting mechanisms 8, both of which are mounted on the frame 1 and located on the same side as the first fabric laying surface 3 and the second fabric laying surface 4 of the fabric laying plate 2, respectively. The two cutting mechanisms 8 are used to cut the fabric that is stacked layer by layer on the first fabric laying surface 3 and the second fabric laying surface 4.

[0024] During operation, the fabric end on the fabric roller 6 is first led out and placed at the end of the fabric laying plate 2. The fabric end is then fixed to the fabric laying plate 2 by the fixing device 5 located at the end of the fabric laying plate 2, at which point the fabric laying plate 2 is in its initial position. Subsequently, the fabric laying plate 2 is driven to rotate around its rotation center line. Under the traction of the fixing device 5, the fabric is continuously released from the fabric roller 6. Since the fabric laying plate 2 has a first laying surface 3 and a second laying surface 4 arranged opposite to each other, the fabric is alternately laid on the two laying surfaces during the rotation of the laying plate. Each half-turn of the fabric laying plate 2 completes one layer of laying on one laying surface. By controlling the number of rotations of the fabric laying plate 2, the required number of layers of fabric can be stacked on the two laying surfaces. When the fabric laying plate 2 rotates to the predetermined number of turns, it stops rotating. At this point, the fabric is laid... One end of the plate 2 is positioned corresponding to the clamp 7 fixed on the frame 1. The clamp 7 presses the fabric at that end against the end face of the fabric plate 2, keeping the fabric wrapped around the fabric plate 2 taut and preventing it from loosening under the clamping action of the clamp 7. Subsequently, the cutting mechanism located on one side of the clamp 7 cuts the fabric laterally along the width direction of the fabric plate 2 at the section of fabric between the clamp 7 and the roll roller 6, completely separating the fabric already stacked on the fabric plate 2 from the roll on the roll roller 6. Finally, the two cutting mechanisms located on the first fabric surface 3 and the second fabric surface 4 of the fabric plate 2 are activated simultaneously to perform graphic cutting on the stacked fabric layers on the two fabric surfaces, cutting the fabric into the required garment piece shape. In the above process, the starting end of the fabric on the fabric laying plate 2 is fixed to the end of the laying plate by the fixing device 5 which rotates with the laying plate, and the ending end of the fabric is pressed by the clamping device 7 fixed on the frame 1 at the end corresponding to the position of the clamping device 7 after the laying plate stops rotating. The end clamped by the clamping device 7 may be the end where the fixing device 5 is located, or it may be the other end of the fabric laying plate 2, depending on the position of the end corresponding to the clamping device 7 when the fabric laying plate 2 stops rotating. This position is determined by the number of fabric layers to be stacked on the two laying surfaces, and there is no need for a fixed positional correspondence between the two.

[0025] This embodiment transforms the traditional planar reciprocating fabric laying into a rotary winding double-sided fabric laying. In the prior art, the fabric laying plate 2 is a fixed planar cutting table, and the fabric can only be stacked back and forth on a single plane. The cutting mechanism can only cut the fabric stack on this single plane, and one cutting action corresponds to one fabric layer on the laying surface. This application sets the fabric laying plate 2 as a rotatable structure, and configures a fixing device 5 that rotates with the laying plate to fix the starting end of the fabric and a clamping device 7 fixed to the frame 1 to press the ending end of the fabric. This allows the fabric to be laid on two opposite laying surfaces simultaneously during the rotation of the laying plate. Thus, a complete laying cycle forms fabric stacks on both laying surfaces, and two cutting mechanisms respectively set on the outside of the two laying surfaces can cut the fabric layers on these two surfaces simultaneously after the laying is completed. Meanwhile, the structural characteristics of the fastener 5, which rotates with the fabric laying plate 2, enable it to always serve as the anchor point for the fabric winding. The clamp 7, which is fixed on the frame 1, clamps the fabric at the end corresponding to the position of the clamp 7 after the fabric is laid. The two work independently and do not interfere with each other. The position of the end clamped by the clamp 7 changes accordingly with the stop angle of the laying plate, which fully adapts to the working requirements under different numbers of fabric layers.

[0026] In summary, this embodiment utilizes the rotation of the fabric laying plate 2 to simultaneously lay the same roll of fabric on the first laying surface 3 and the second laying surface 4, and configures two cutting mechanisms to simultaneously cut the fabric on both laying surfaces. This doubles the fabric processing capacity within the same laying and cutting time using the same roll of fabric. This embodiment breaks through the limitations of existing single-sided laying operation modes, fundamentally changes the fabric stacking method, and provides a new technical path for improving cutting efficiency, thereby significantly enhancing cutting efficiency.

[0027] In addition, this implementation uses a plate-laying rotation to cooperate with the fabric rolling roller 6 to achieve plate laying. Its laying efficiency is simpler and the manufacturing cost is lower than that of the traditional reciprocating plate-laying structure, and its laying efficiency is also higher.

[0028] It is worth noting that in this embodiment, the number of fabric layers stacked on the two fabric surfaces can be precisely controlled by controlling the number of rotations of the fabric laying plate 2. The fabric is evenly wrapped around the two fabric surfaces during the rotation of the laying plate. Since the rotation axis of the fabric rolling roller 6 is parallel to the rotation center line of the fabric laying plate 2, and the two ends of the fabric rolling roller 6 along its axial direction are aligned with the two sides of the fabric laying plate 2 along its width direction, the alignment between fabric layers is good after the fabric is laid on the fabric laying plate 2, which can effectively prevent wrinkles and displacement of the stacked fabric.

[0029] In this embodiment, the processes of laying, fixing, cutting, and trimming are completed continuously on the same equipment, eliminating the need to transfer fabric between different workstations. This reduces waiting time between processes and fabric handling, further improving overall production efficiency.

[0030] Furthermore, in this embodiment, the aforementioned fastener 5 includes a telescopic member 501 and a clamping member. A strip groove 14 is formed along the width direction at the end of the fabric panel 2, and the clamping member is a pressing strip 502 adapted to the strip groove 14. The telescopic member 501 is disposed on both sides of the fabric panel 2, and the telescopic end of the telescopic member 501 is connected to the pressing strip 502, used to drive the pressing strip 502 to move along the depth direction of the strip groove 14, so as to press and fix the fabric end extending into the strip groove 14. The fabric panel 2 stops at the initial position, and the operator leads out the fabric end on the fabric rolling roller 6 and pulls it to the end of the fabric panel 2, extending the fabric end into the strip groove 14 formed at the end of the fabric panel 2. After the fabric end extends to an appropriate depth, the telescopic components 501 located on both sides of the fabric panel 2 are activated. The telescopic ends of the telescopic components 501 extend, driving the connected clamping strip 502 to move along the depth direction of the strip groove 14. The clamping strip 502 moves towards the bottom wall of the strip groove 14, pressing the fabric end extending into the strip groove 14 between the clamping strip 502 and the bottom wall of the strip groove 14, thus fixing the fabric end at the end of the fabric panel 2. In this way, the cooperation structure between the strip groove 14 and the clamping strip 502 achieves uniform clamping of the fabric end throughout the entire width direction, avoiding local deformation or damage to the fabric that is easily caused by point clamping methods, ensuring the reliability of the fabric end fixing and the integrity of the fabric.

[0031] Specifically, in this embodiment, the aforementioned telescopic component 501 is a hydraulic telescopic cylinder, which can effectively press and fix the fabric within the strip groove 14. At the same time, after the pressing strip 502 is pressed into the strip groove 14, the pressing strip 502 actually fills the strip groove 14, and the exposed surface of the pressing strip 502 is basically flush with the fabric laying surface of the fabric laying board 2, so it will not affect the laying and cutting of the fabric.

[0032] In this embodiment, the clamping device 7 includes a jaw 702 and a telescopic device 701. The telescopic device 701 is mounted on the frame 1, and its telescopic end extends and retracts along a radial direction passing through the rotation center of the fabric laying plate 2. The jaw 702 is located at the telescopic end of the telescopic device 701. The jaw 702 is used to press the fabric end against the end of the fabric laying plate 2, thereby clamping and fixing the fabric. The telescopic device 701 is used to drive the jaw 702 to extend and retract. The extension and retraction of the telescopic end of the telescopic device 701 along the radial direction passing through the rotation center of the fabric laying plate 2 allows the jaw 702 to stably clamp the fabric end in that direction.

[0033] Furthermore, in this embodiment, the two cutting mechanisms 8 are symmetrically arranged on both sides of the diameter line where the telescopic member 701 is located, and the two cutting mechanisms 8 are centrally symmetrically arranged with respect to the rotation center line of the fabric laying plate 2. The diameter line where the telescopic member 701 is located refers to the radial direction passing through the rotation center line of the fabric laying plate 2, and the telescopic member 501 of the fixing device 5 is located in the extension direction of this diameter line. After the fabric laying plate 2 fixes the starting end of the fabric at the end where the fixing device 5 is located, it begins to rotate. During the rotation of the laying plate, the fabric is wrapped around the outer periphery of the fabric laying plate 2 layer by layer, and alternately laid on the first laying surface 3 and the second laying surface 4. During this process, the two cutting mechanisms respectively located on both sides of the diameter line where the telescopic member 501 is located are always ready in their respective areas. When the fabric laying plate 2 rotates to a predetermined number of turns and stops rotating, the gripper 702 presses the ending end of the fabric. At this time, the two cutting mechanisms 8 are located on both sides of the first laying surface 3 and the second laying surface 4, respectively. In this way, the cutting mechanism 8 can complete the cutting of the corresponding laying surface.

[0034] Furthermore, in this embodiment, each of the above-mentioned cutting mechanisms 8 includes a three-axis slide module 801 and a cutting tool 802. The three-axis slide module 801 is mounted on the frame 1, and the cutting tool 802 is mounted on the moving end of the three-axis slide module 801. The three moving axes of the three-axis slide module 801 are arranged along the width direction, length direction, and thickness direction of the fabric laying board 2, respectively.

[0035] In this embodiment, when the fabric laying plate 2 completes a predetermined number of rotations and the clamping device 7 presses the end of the fabric, the cutting shears near the fabric roll are moved to the clamping device 7 under the drive of the corresponding three-axis slide module 801. Then, under the drive of the three-axis slide module 801, the fabric is laterally cut along the width direction. At this point, the fabric on the fabric laying plate 2 separates from the fabric on the fabric roll, facilitating subsequent cutting work by the two cutting mechanisms 8. At the start of the cutting operation, the three-axis slide module 801 drives the cutting shears 802 to move to the cutting start position in three-dimensional space. Specifically, the three-axis slide module 801 moves the cutting tool 802 along the width direction (i.e., the X-axis) of the fabric panel 2, positioning it at the starting point of the cutting pattern in the width direction of the fabric; moves the cutting tool 802 along the length direction (i.e., the Y-axis) of the fabric panel 2, positioning it at the starting point of the cutting pattern in the length direction of the fabric; and moves the cutting tool 802 along the thickness direction (i.e., the Z-axis) of the fabric panel 2, lowering it to contact the upper surface of the fabric stack layer or to reach a preset cutting depth.

[0036] Subsequently, the three-axis slide module 801 drives the cutting tool 802 to move in linkage along the width and length directions of the fabric panel 2 according to the preset cutting pattern path. Simultaneously, it makes fine adjustments in the thickness direction according to the fabric thickness and cutting process requirements, ensuring that the cutting tool 802 cuts on the fabric stack layer along a predetermined trajectory. Because the three-axis slide module 801 can perform precise linkage control in three directions, the cutting tool 802 can cut garment pieces of any shape, including straight lines, curves, arcs, and various complex contours. During the cutting process, the cutting mechanism located on one side of the first fabric panel 3 cuts the fabric stack layer on the first fabric panel 3, while another cutting mechanism located on one side of the second fabric panel 4 simultaneously cuts the fabric stack layer on the second fabric panel 4. The three-axis slide modules 801 of the two cutting mechanisms independently drive their respective cutting tools 802 to move along preset paths, allowing them to execute the exact same cutting pattern or different cutting patterns. After cutting is completed, the three-axis slide module 801 drives the cutting tool 802 to move, so that it is no longer in contact with the fabric, and waits for the next work cycle.

[0037] It should be noted that after the three-axis slide module 801 drives the cutting tool 802 to move away from the fabric, the cutting tool 802 needs to be moved to a position completely away from the rotation area of ​​the fabric laying plate 2, so as not to affect the normal rotation and stacking of new fabric on the fabric laying plate 2.

[0038] In this embodiment, the aforementioned three-axis slide module 801 is an existing precision linear motion module, typically comprising three mutually orthogonal linear motion axes. Each motion axis consists of a guide rail, a slider, a drive motor 10, and a transmission mechanism (such as a ball screw or synchronous belt). The three motion axes are arranged along the width, length, and thickness directions of the fabric panel 2, respectively, forming a complete Cartesian coordinate system motion system. The cutting tool 802 is fixedly mounted on the moving end of the three-axis slide module 801 (i.e., on the slider of the Z-axis slide). Driven by the three-axis slide module 801, the cutting tool 802 can reach any position on the surface of the fabric panel 2 in three-dimensional space and cut the fabric at any angle and depth. The three-axis slide module 801 realizes the precise positioning and flexible movement of the cutting tool 802 in three-dimensional space, enabling the cutting mechanism to cut garment pieces of any shape, meeting the cutting needs of various garment styles, and greatly improving the applicability and versatility of the equipment.

[0039] The arrangement of the three moving axes determines the range of motion and working accuracy of the cutting tool 802. Movement in the width direction (X-axis) allows the cutting tool 802 to traverse the entire width of the fabric panel 2, covering the entire cutting area of ​​the fabric in the width direction; movement in the length direction (Y-axis) allows the cutting tool 802 to move along the length direction of the fabric panel 2, covering the entire cutting area of ​​the fabric in the length direction; movement in the thickness direction (Z-axis) allows the cutting tool 802 to feed and retract along the thickness direction of the fabric panel 2, controlling the cutting depth to accommodate fabric stacks of different thicknesses. Optionally, in this embodiment, the cutting tool 802 is any one of a vibrating knife, a laser cutting head, or a disc cutter. Vibrating knives, laser cutting heads, and disc cutters are all existing technologies. The vibrating knife mainly consists of a blade body, a handle, a vibration drive mechanism, and a blade. The vibration drive mechanism is typically an electromagnet or piezoelectric ceramic actuator, capable of converting electrical energy into high-frequency mechanical vibration, driving the blade to perform a small reciprocating motion in the Z-axis direction. The blade of the vibrating knife is usually made of a high-hardness alloy material, possessing a sharp edge and good wear resistance, capable of adapting to the cutting needs of various types of fabrics. The laser cutting head mainly consists of a laser, an optical path system, a focusing lens, and a protective lens. The laser beam generated by the laser is transmitted to the cutting head through the optical path system, and after being focused by the focusing lens, forms a high-energy-density light spot that acts on the fabric surface. The power and focused spot size of the laser cutting head can be adjusted according to the material and thickness of the fabric to adapt to the requirements of different cutting processes. The disc cutter mainly consists of a cutter disc, a cutter shaft, and a drive motor 10. The cutter head is circular with sharp blades along its edges. It is connected to the drive motor 10 via a cutter shaft. The drive motor 10 rotates the cutter head at high speed, creating a continuous shearing motion. The blades of the circular cutter are typically made of cemented carbide or high-speed steel, offering good wear resistance and impact resistance. The aforementioned vibrating cutter is suitable for various fabric materials, especially for cutting where high edge quality is required. The laser cutting head is suitable for cutting thin fabrics and intricate patterns, offering high cutting speed and precision. The circular cutter is suitable for thick fabrics and cutting primarily straight lines, offering high cutting efficiency and low cost. Therefore, users can select one of the above-mentioned cutting tools 802 according to their actual cutting needs.

[0040] In some embodiments of this example, the fabric rolling roller 6 includes a cylinder 601 and a rotating shaft 602. The cylinder 601 is disposed on the rotating shaft 602, and the rotating shaft 602 is rotatably disposed on the frame 1. A damping element 13 is disposed between the rotating shaft 602 and the frame 1 to dampen the rotation of the rotating shaft 602 and the frame 1.

[0041] During operation, the fabric laying plate 2 rotates around its rotation center line. The starting end of the fabric, fixed to the end of the fabric laying plate 2, rotates together with the laying plate. Under the traction force generated by the rotation of the laying plate, the fabric is continuously released from the fabric roll. During this process, the shaft 602 of the fabric rolling roller 6 rotates on the frame 1, and the cylinder 601 rotates synchronously with the shaft 602. The fabric roll is rotated and released under the drive of the cylinder 601. Since a damping element 13 is provided between the shaft 602 and the frame 1, the shaft 602 is always subjected to a damping torque applied by the damping element 13 during rotation. The direction of this damping torque is opposite to the rotation direction of the shaft 602, so that the fabric always bears a certain tension when released from the fabric rolling roller 6, and will not suddenly loosen or over-release due to changes in the rotation speed of the laying plate or inertia.

[0042] Specifically, in this embodiment, the aforementioned fabric rolling roller 6 consists of two core components: a cylinder 601 and a rotating shaft 602. The cylinder 601 is coaxially fixed on the rotating shaft 602, forming a rigid whole. The cylinder 601 is a cylindrical hollow structure, and its outer surface is used to support and fix the rolled fabric. The outer diameter of the cylinder 601 matches the inner diameter of the fabric roll, ensuring that the fabric roll can be tightly fitted onto the cylinder 601 without relative slippage. The length of the cylinder 601 matches the width of the fabric laying plate 2, that is, the two ends of the cylinder 601 along its axial direction are aligned with the two sides of the fabric laying plate 2 along its width direction, so that after the fabric is released from the fabric rolling roller 6, it can be laid flat on the surface of the laying plate with a width that completely corresponds to the width of the fabric laying plate 2, avoiding the fabric from shifting or wrinkling in the width direction.

[0043] The two ends of the rotating shaft 602 are rotatably mounted on the frame 1 via bearing seats. Rolling or sliding bearings are installed inside the bearing seats to support the rotating shaft 602 and reduce rotational friction. One or both ends of the rotating shaft 602 extend beyond the bearing seats and connect to the damping element 13. The damping element 13 is positioned between the rotating shaft 602 and the frame 1. Its specific installation method can be as follows: the damping element 13 is fitted onto the end of the rotating shaft 602, the outer shell of the damping element 13 is fixed to the frame 1, and the inner ring of the damping element 13 is fixedly connected to the rotating shaft 602; or one end of the damping element 13 is connected to the rotating shaft 602, and the other end is connected to the frame 1, generating a resistance torque through the damping medium or friction element inside the damping element 13.

[0044] Optionally, in this embodiment, the damping element 13 is existing technology and can be any one of a friction damper, a magnetic powder brake, or a hydraulic damper. When it is a friction damper, it generates a constant damping torque by relying on the friction between the friction plates, which is simple in structure and low in cost. When it is a magnetic powder brake, it adjusts the damping torque by controlling the magnitude of the excitation current, which can achieve stepless adjustment and high tension control accuracy. When it is a hydraulic damper, it generates a damping torque by relying on the flow resistance of hydraulic oil in the throttle orifice, which has stable damping characteristics and long service life. Regardless of the type of damping element 13 used, its core function is to provide a resistance torque that is independent of the rotation speed or positively correlated with the rotation speed when the shaft 602 rotates, so that the fabric always bears a constant tension during the release process, avoiding fabric loosening and wrinkling due to insufficient tension or fabric stretching and deformation due to excessive tension, ensuring the flatness of the fabric laid on the board, and avoiding problems such as fabric offset and wrinkles.

[0045] Preferably, in this embodiment, a rotating mechanism is provided between the fabric laying plate 2 and the frame 1. The rotating mechanism includes two rotating frames 9, which are symmetrically fixed on both sides of the fabric laying plate 2 along its width direction. The two rotating frames 9 are coaxially rotatably mounted on the frame 1 via the same central axis. A driving mechanism is connected to either rotating frame 9, which drives the rotating frame 9 to rotate around the central axis, thereby causing the fabric laying plate 2 to rotate around its rotation center line. The rotating mechanism, with the two rotating frames 9 symmetrically arranged on both sides of the fabric laying plate 2, achieves dual-point support and symmetrical force on the fabric laying plate 2, making the fabric laying plate 2 subjected to uniform force during rotation and cutting, reducing vibration and deformation caused by eccentric loading, and improving the stability of the laying plate operation.

[0046] Preferably, in this embodiment, limiting plates 11 are respectively provided on both sides of the fabric laying plate 2 along its width direction. The limiting plates 11 extend along the length direction of the fabric laying plate 2 and protrude from the surface of the fabric laying plate 2, used to constrain the position of the fabric in the width direction. Specifically, in this embodiment, the driving mechanism is a drive motor 10, which is mounted on the frame 1 and directly connected to one of the rotating frames 9 to drive the rotating frame 9 to rotate. The two limiting plates 11 extend along the length direction of the fabric laying plate 2, and their length matches the length of the fabric laying plate 2, that is, the limiting plates 11 extend from one end of the fabric laying plate 2 to the other end, covering the entire laying area of ​​the fabric laying plate 2. The length direction of the limiting plates 11 is parallel to the length direction of the fabric laying plate 2, the width direction of the limiting plates 11 is perpendicular to the width direction of the fabric laying plate 2, and the height direction of the limiting plates 11 is parallel to the thickness direction of the fabric laying plate 2. The limiting plate 11 protrudes from the surface of the fabric laying plate 2, and its protrusion height is determined according to the maximum thickness of the stacked fabric. Specifically, the protrusion height of the limiting plate 11 should not be less than the maximum total thickness of the stacked fabric on the fabric laying plate 2, so as to ensure that when the number of fabric stacking layers reaches the maximum value, the limiting plate 11 can still restrain the side of the topmost fabric layer. In this embodiment, the protrusion height of the limiting plate 11 is 10mm to 50mm, and the specific value is determined according to the design of the number of fabric laying layers of the equipment and the thickness of a single layer of fabric.

[0047] In this embodiment, limiting plates 11 are set on both sides of the fabric laying plate 2 to forcibly constrain the fabric in the width direction during the process of the fabric being wrapped around the surface of the laying plate. This effectively prevents the fabric from shifting, curling or slipping due to centrifugal force, tension fluctuation or uneven width during the rotation of the laying plate, ensuring that each layer of fabric is neatly aligned in the width direction, and providing an accurate fabric position reference for subsequent cutting.

[0048] In some embodiments of this example, the fabric supply assembly further includes a guide roller 12. The guide roller 12 is rotatably mounted on the frame 1 and located between the fabric roll roller 6 and the fabric laying plate 2. The axis of the guide roller 12 is parallel to the axis of the fabric roll roller 6. After the fabric is drawn out from the fabric roll roller 6, it passes through the guide roller 12 and enters the surface of the fabric laying plate 2. The guide roller 12 is a roller assembly structure, and the fabric can pass through the gaps in the roller assembly structure. The guide roller 12 can guide the movement direction of the fabric, so that the fabric smoothly transitions from the output direction of the fabric roll roller 6 to the direction required to enter the fabric laying plate 2, avoiding creases, wrinkles, or twists caused by sudden changes in direction during the transmission of the fabric, and further ensuring the flatness and directional consistency of the fabric when it enters the laying plate surface.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
