Description

Technical Field

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

[0002] In the field of modern mattress manufacturing, 3D fabrics, with their unique breathable structure, high elastic deformation recovery ability, and excellent mechanical support properties, have become the core material for new mattress cores. The 3D fabric production line, as the core equipment for producing this material, generates three-dimensional mesh panels through a continuous production mode.

[0003] Currently, mainstream cutting equipment in the industry still uses traditional mechanical transmission and fixed parameter control modes. The control system relies on preset programs to execute cutting tasks with fixed widths and fixed lengths. That is, existing cutting equipment can only cut products with fixed widths to fixed lengths, which cannot meet diverse production needs. For example, when the market needs to produce sleeper cores for both children's beds and adult beds at the same time, the core length required for children's beds is shorter, while that for adult beds is longer. Existing cutting equipment cannot cut the two products to different lengths at the same time, and can only operate in batches, resulting in a significant reduction in production efficiency. In particular, the need to stop and debug the equipment in the middle further exacerbates the problem of low production efficiency.

[0004] Therefore, the single cutting method limits the flexible production capacity of 3D fabric production lines, making it difficult to adapt to rapidly changing market demands. When faced with small-batch, multi-specification orders, the equipment has low flexibility and low production efficiency. Adjustments to equipment parameters can also lead to downtime for debugging, resulting in extended production cycles and significantly increased energy costs. Utility Model Content

[0005] To address the technical problem that existing cutting equipment can only cut products of fixed width to fixed length, making it difficult to adapt to rapidly changing market demands and resulting in low equipment flexibility and low production efficiency when facing small-batch, multi-specification orders, this utility model provides a multi-channel fabric cutting device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-channel fabric cutting device includes a frame on which several parallel rollers are rotatably mounted. The axial direction of each roller is transverse, and the rollers are spaced apart longitudinally. A transversely extending guide rail is mounted on the frame. The upper surface of the guide rail is lower than or flush with the highest point of the outer circumference of the roller. The guide rail is located between any two adjacent rollers. Four vertical plates are slidably and detachably mounted on the guide rail. The plates are vertically oriented, and their length is longitudinal. A table is provided on one side of the frame in the longitudinal direction. A cutting device, including a cutter, is mounted on the top of the table. The cutter is movable in both the transverse and vertical directions. Two limiting devices are provided on the other side of the frame in the longitudinal direction. The two limiting devices are respectively arranged on the transverse sides of the frame. Each limiting device is movable in the longitudinal direction of the frame and includes a limit switch.

[0008] Using the above structural design, roller one provides stable support and a stable conveying path for the fabric. The upper surface of guide rail one is lower than or flush with the highest point of the outer circumference of roller one, ensuring a smooth transition of the fabric and reducing jamming during conveying. Four detachable uprights can be flexibly adjusted in layout according to the width and quantity of the fabric to meet the placement requirements of fabrics of different specifications. The limit switch of the limit device can accurately control the conveying length of the fabric, avoiding inaccurate cutting dimensions caused by human judgment errors. Two limit devices are provided, allowing the equipment to control the cutting length of two fabrics. The cutting device's blade can move in both horizontal and vertical directions, allowing the blade to cut at any position with controllable cutting distance. This equipment can not only cut a single wide fabric but also cut two narrow fabrics of the same or different cutting lengths, resulting in high production efficiency.

[0009] As a preferred implementation of a multi-channel fabric cutting device, the cutting device includes a gantry truss, the length of which is arranged laterally. A transversely extending track is provided along the length of the truss, and a transverse moving seat is slidably mounted on the track. The transverse moving seat is connected to a transverse linear drive mechanism, which can drive the transverse moving seat to slide on the track. A vertically arranged track is provided at the bottom of the transverse moving seat, and a vertical moving seat is slidably mounted on the track. The vertical moving seat is connected to a vertical linear drive mechanism, which can drive the vertical moving seat to slide on the track. The cutting tool is mounted on the vertical moving seat.

[0010] The above-mentioned structural scheme adopts a gantry truss structure with a horizontal moving seat and a vertical moving seat. The horizontal linear drive mechanism and the vertical linear drive mechanism drive the cutter to move in the horizontal and vertical directions respectively, so that the cutter can move flexibly in the two-dimensional plane, quickly adjust the cutter position and cutting distance, greatly improve the flexibility and adaptability of the cutting equipment, and effectively solve the problem that the existing equipment can only perform fixed-length and fixed-position cutting.

[0011] As a preferred implementation of a multi-channel fabric cutting device, the table surface is flush with the highest point of the outer circumference of the roller, and the table surface has a horizontally arranged cutting slit, which is vertically opposite to the cutting tool.

[0012] With the above structural design, the tabletop is flush with the highest point of the outer circumference of roller one, preventing the fabric from wrinkling or being stretched due to height differences. The cutting slits on the tabletop are aligned vertically with the cutting tool, allowing the tool sufficient space to smoothly cut into and out of the fabric, preventing fabric displacement or damage to the tool during cutting, ensuring cutting stability and quality, and reducing the defect rate.

[0013] As a preferred implementation of a multi-channel fabric cutting device, two pressure plate devices are installed on the top of the table, located on opposite sides of the cutting device along its longitudinal direction. Each pressure plate device includes a gantry truss II, with each truss II arranged laterally along its length. A laterally arranged support rod is installed on the inner side of each truss II, and a pressure rod is provided below each support rod. Each pressure rod is also arranged laterally along its length and is divided into two equal sections in the lateral direction. Two cylinders I are installed at the top of each support rod, and the telescopic shaft of each cylinder I slides vertically downward through the support rod and connects to the top of one section of the pressure rod. A guide rod is installed at the top of each section of the pressure rod, and the guide rod slides vertically upward through the support rod.

[0014] Using the above structural design, the pressure plate devices on both sides of the table top, through the cooperation of gantry truss II, support rods, pressure rods, and cylinder I, can press and fix the fabric before cutting. During the cutting process, it effectively prevents the fabric from shifting due to vibrations generated by the cutting tool, ensuring the accuracy of the cutting dimensions. The pressure rod is designed in sections and is controlled by two cylinders I, allowing for independent pressing of two fabrics.

[0015] As a preferred implementation of a multi-channel fabric cutting device, a helical spring is installed at the bottom of the side of each pair of pressure bars that is away from each other. The helical spring is set vertically and its bottom abuts against the table surface.

[0016] With the above structural design, the helical spring installed at the bottom of the pressure rod plays a buffering role. When the cylinder drives the pressure rod to press down, the helical spring can absorb part of the pressure and prevent the pressure rod from causing hard damage to the fabric.

[0017] In a preferred implementation of a multi-channel fabric cutting device, each limiting device includes a longitudinally arranged guide rail II, which is fixedly connected to the frame. A slider II is slidably mounted on the upper surface of the guide rail II, and the slider II is connected to a longitudinal linear drive mechanism, which drives the slider II to move along the guide rail II. A cylinder II is mounted on the upper surface of the slider II, and the telescopic shaft of the cylinder II is connected to a rack. The rack is arranged longitudinally along its length and meshes with a gear. The gear is coaxially connected to a gear shaft, which is arranged transversely along its axial direction. A bearing is mounted on the outer circumferential surface of the gear shaft, and the bearing is connected to the slider II via a bearing seat. The outer circumferential surface of the gear shaft is connected to the support... The support plate is fixedly connected to the support plate. The length of the support plate is set laterally. One side of the support plate is connected to the rectangular mounting side plate in the width direction. The support plate is perpendicular to the mounting side plate. The length of the mounting side plate is set laterally. A limit switch is installed on the side of the mounting side plate away from the support plate in the width direction. The side of the mounting side plate away from the support plate in the width direction is connected to a limit plate. The limit plate is set parallel to the mounting side plate. When the limit plate rotates with the gear shaft to the bottom of the support plate and is in a vertical position, the limit switch is located on the side of the limit plate facing the table.

[0018] Using the above structural design, the limiting device can move flexibly in the longitudinal direction, and the position of the limit switch can be quickly adjusted according to the cutting length requirements of different fabrics. The transmission structure of cylinder two, rack, gear, and gear shaft enables the limiting plate to flip. When the fabric is conveyed to the correct position and triggers the limit switch, the limiting plate flips to a horizontal position to facilitate the passage of the cut fabric; after the fabric has passed, the limiting plate flips back to the limiting position to continue limiting subsequent fabrics.

[0019] As a preferred implementation method for multi-channel fabric cutting equipment, the limiting plate has several drag-reducing holes on its surface.

[0020] By adopting the above structural scheme, the drag-reducing holes opened on the limit plate can reduce the air resistance during the limit plate's flipping process, making the limit plate's flipping action smoother, reducing the wear of transmission components, reducing the noise during equipment operation, and improving the stability and reliability of equipment operation.

[0021] As a preferred implementation of a multi-channel fabric cutting device, a longitudinally set scale is installed on the upper surface of the guide rail two.

[0022] With the above structural design, the longitudinal scale installed on the guide rail provides an intuitive scale reference for operators to adjust the position of the limit switch, making it easy to quickly and accurately adjust the limit switch to the required position and avoid inaccurate cutting length due to manual measurement errors.

[0023] As a preferred implementation of a multi-channel fabric cutting device, there are two guide rails, which are located at the bottom of both sides of the vertical plate in the longitudinal direction.

[0024] With the above structural design, two guide rails are located at the bottom of the vertical plate on both sides, providing stable support and guidance for the plate. Compared with a single guide rail, the dual guide rail structure can better bear the weight of the plate and the fabric placed on it, preventing the plate from tilting or swaying during movement or load-bearing, ensuring the stability of fabric placement and conveying, and thus improving cutting accuracy and equipment operation reliability.

[0025] As a preferred implementation of a multi-channel fabric cutting device, four sliders are slidably installed on the upper surface of each guide rail, each vertical plate is vertically connected to a mounting plate, the mounting plate is horizontally set, the length direction of the mounting plate is set longitudinally, and the two sides of the mounting plate in the length direction are connected to the two guide rails respectively through a slider. The mounting plate and the slider are connected by bolts.

[0026] With the above structural design, the slider on the guide rail is connected to the upright plate through a mounting plate and bolts, making the installation and disassembly of the upright plate more convenient.

[0027] The beneficial effects of this utility model include:

[0028] Four detachable uprights allow for flexible layout adjustments based on fabric width and quantity, accommodating different fabric specifications. Limit switches on the positioning devices precisely control the fabric conveying length, preventing inaccurate cutting dimensions due to human error. Two limit switches allow for length control of two fabrics. The cutting blades can move horizontally and vertically, enabling them to cut at any position with controllable cutting distance. This equipment can cut not only single wide fabrics but also two narrow fabrics of the same or different cutting lengths, offering high production efficiency and flexibility to handle small-batch, multi-specification orders.

[0048] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Reference Figure 1-7 This embodiment proposes a multi-channel fabric cutting device, including a frame 1, a table 5, a cutting device 6, a pressure plate device 8, a limiting device 7, a conveying device 11, and a control operator 12. The actions of the cutting device 6, the pressure plate device 8, the limiting device 7, and the conveying device 11 are all automatically controlled by the control operator 12. Operators can also manually operate the control operator 12 to control the actions and operating parameters of the cutting device 6, the pressure plate device 8, the limiting device 7, and the conveying device 11.

[0050] Several parallel rollers 2 are rotatably mounted on the frame 1. The axial direction of each roller 2 is arranged in the transverse direction. The rollers 2 are arranged at intervals in the longitudinal direction. The rollers 2 provide rolling support for the fabric driven by the conveying device 11, so that the fabric can continue to be conveyed.

[0051] The frame 1 is equipped with two horizontally extending guide rails 3. The two guide rails 3 are distributed in the longitudinal direction. The two guide rails 3 are the same and their upper surfaces are at the same height. The two guide rails 3 are located between any two adjacent rollers 2. The upper surfaces of the two guide rails 3 are either lower than or at the highest point of the outer circumference of the roller 2, so as to avoid affecting the continued conveying of the fabric from the conveying device 11. Four sliders 9 are slidably mounted on the upper surface of each guide rail 3. The sliders 9 on the two guide rails 3 are arranged longitudinally opposite each other in pairs. A mounting plate 10 is connected to each pair of sliders 9 that are opposite each other in the longitudinal direction on the two guide rails 3. The mounting plate 10 and the sliders 9 are detachably connected by bolts. The plate surface of the mounting plate 10 is horizontal and the length direction of the mounting plate 10 is longitudinal. A vertical plate 4 is connected to the upper surface of each mounting plate 10. The plate surface of the vertical plate 4 is vertical and the length direction of the plate surface is longitudinal. That is, a total of four vertical plates 4 are detachably slidably mounted on the two guide rails 3.

[0052] Reference Figure 8 By removing the four uprights 4 from the frame 1, this device can cut a single wide fabric. In other embodiments, only two uprights 4 are provided on the frame 1. By adjusting the distance between the two uprights 4 so that the lateral distance between the two uprights 4 matches the width of the fabric, this device can cut a single narrow fabric. (Refer to...) Figure 9 and Figure 10 The frame 1 is equipped with four upright plates 4, which are arranged in pairs. Each pair of upright plates 4 forms a channel for the fabric to pass through. This equipment can cut two narrow fabrics.

[0053] A table 5 is provided on one side of the frame 1 along its longitudinal direction. The table surface of the table 5 is flush with the highest point of the outer periphery of the roller 2. A cutting device 6 is installed on the top of the table 5. The cutting device 6 includes a gantry truss 62, which is arranged laterally along its length. A laterally extending track 63 is provided along the length of the truss 62. A transverse moving seat 64 is slidably mounted on the track 63. The transverse moving seat 64 is connected to a transverse linear drive mechanism (not shown in the figure), which can drive the transverse moving seat 64 to slide on the track 63. The horizontal moving seat 64 has a vertically arranged second track 65 at its bottom. A vertical moving seat 66 is slidably mounted on the second track 65. The vertical moving seat 66 is connected to a vertical linear drive mechanism (not shown in the figure). The vertical linear drive mechanism can drive the vertical moving seat 66 to slide on the second track 65. The cutter 61 is mounted on the vertical moving seat 66. Under the drive of the horizontal moving seat 64 and the vertical moving seat 66, the cutter 61 can move in the horizontal and vertical directions respectively. Thus, the cutting position and horizontal cutting distance of the cutter 61 can be controlled. The table surface of the table 5 has a horizontally arranged cutting slit 51, which is vertically opposite to the cutter 61. In this embodiment, the horizontal linear drive mechanism and the vertical linear drive mechanism can be linear motors. Those skilled in the art are familiar with the installation method and working principle of linear motors.

[0054] Two limiting devices 7 are provided on the other side of the longitudinal direction of the frame 1. The two limiting devices 7 are respectively arranged on the transverse sides of the frame 1, and each limiting device 7 can move along the longitudinal direction of the frame 1. Each limiting device 7 includes a longitudinally arranged guide rail 72, which is fixedly connected to the frame 1. A longitudinally arranged scale 710 is installed on the upper surface of the guide rail 72, and a slider 711 is slidably installed on the upper surface of the guide rail 72. The slider 711 is connected to a longitudinal linear drive mechanism (not shown in the figure). The moving distance of the slider 711 can be referenced to the scale on the scale 710. The longitudinal linear drive mechanism can drive the slider 711 to move along the guide rail 72. The longitudinal linear drive mechanism can be a linear motor. A cylinder 73 is mounted on the upper surface of slider 711. The axial direction of the telescopic shaft of cylinder 73 is longitudinal. The telescopic shaft of cylinder 73 is connected to rack 74. The length direction of rack 74 is longitudinal. Rack 74 meshes with gear 75. Gear 75 is coaxially connected to gear shaft. The axial direction of gear shaft is transverse. A bearing is mounted on the outer circumferential surface of gear shaft. The bearing is connected to slider 711 through a bearing seat. The bearing seat supports the bearing and the bearing rotates to support the gear shaft. The outer circumferential surface of gear shaft is fixedly connected to the surface of support plate 76. Support plate 76 can rotate with gear shaft. The length direction of support plate 76 is transverse. One side of the width direction of support plate 76 is connected to a rectangular mounting side plate 77. The surface of support plate 76 is perpendicular to the surface of mounting side plate 77. The length direction of mounting side plate 77 is transverse. A limit switch 71 is mounted on the side of mounting side plate 77 away from support plate 76 in the width direction. The side of the mounting side plate 77, away from the support plate 76 in the width direction, is connected to the limiting plate 78. The surface of the limiting plate 78 is parallel to the surface of the mounting side plate 77. Several drag-reducing holes 79 are opened on the surface of the limiting plate 78 to reduce wind resistance during flipping. When the limiting plate 78 rotates with the gear shaft to the bottom of the support plate 76 and is in a vertical position, the limit switch 71 is located on the side of the limiting plate 78 facing the table 5.

[0055] The limiting plate 78 can move along the slider 711 on the longitudinally arranged guide rail 72. The longitudinal distance between the limiting plate 78 and the cutting tool 61 is the required length of the fabric.

[0056] Two pressure plate devices 8 are installed on the top of the table 5, located on either side of the cutting device 6 along its longitudinal direction. Each pressure plate device 8 includes a gantry truss 81, with each truss 81 extending laterally. A laterally positioned support rod 82 is installed on the inner side of each truss 81. Below each support rod 82 is a pressure rod 86, a rectangular hollow pressure rod 86, also extending laterally and divided into two equal sections. Two cylinders 83 are installed at the top of each support rod 82. The telescopic shaft of each cylinder 83 slides vertically downwards through the support rod 82 and connects to the top of the pressure rod 86 section directly below it. A guide rod 84 is installed at the top of each pressure rod 86 section, sliding vertically upwards through the support rod 82. Both pressure bars 86 have a helical spring 85 installed at the bottom of the side furthest from each other. The helical spring 85 is vertically set and its bottom abuts against the table surface of the table 5. The position of the helical spring 85 does not obstruct the fabric conveying. The two cylinders 83 of each pressure plate device 8 can work independently, allowing the two pressure bars 86 to operate independently, thereby pressing two narrow fabrics separately.

[0057] Reference Figure 1 and Figure 7 A conveying device 11 is provided on the side of the table 5 away from the frame 1. The conveying device 11 can actively convey fabric. The conveying device 11 includes a conveying frame 111, on which several parallel rollers 112 are rotatably mounted. The axial direction of each roller 112 is arranged laterally, and the rollers 112 are arranged longitudinally at intervals. The highest point of the outer circumference of each roller 112 is flush with the highest point of the outer circumference of each roller 112 to ensure that the fabric is conveyed without jamming. Each roller 112 is equipped with a drive sprocket 113, and the drive sprockets 113 on the rollers 112 are connected by a drive chain 114. The conveying frame 111 is equipped with a servo motor 115 connected to one of the drive sprockets 113, so that each roller 112 can rotate around its own central axis. (Refer to...) Figure 7 The same upright plate 4 as that on the frame 1 is also slidably provided on the conveyor frame 111.

[0058] For each limiting device 7, in the limiting state, the limiting plate 78 is located at the bottom of the support plate 76 and is in a vertical position. The bottom edge of the limiting plate 78 is above the highest point of the outer circumference of the roller 2. The gap between the bottom edge of the limiting plate 78 and the highest point of the outer circumference of the roller 2 is smaller than the thickness of the fabric to prevent the fabric from passing through. When the fabric is conveyed to contact the limit switch 71, the control operator 12 controls the conveying device 11 to stop, and at the same time controls the pressure plate device 8 and the cutting device 6 to operate. The pressure plate device 8 presses down on the fabric, and the cutting device 6 cuts the fabric. After the cutting is completed, the pressure plate device 8 and the cutting device 6 return to their original positions. The cylinder 73 drives the rack 74 to move, causing the gear 75 to rotate, which drives the limiting plate 78 to flip to a horizontal state. At this time, the conveying device 11 is turned on, and the cut fabric can pass through. After the cut fabric passes through, the limiting plate 78 flips to the limiting state.

[0059] Work process:

[0060] Depending on the fabric specifications to be cut (single width / double narrow width), the upright plates 4 are removed or installed using bolts: if cutting single width fabric, remove all upright plates 4; if cutting double narrow width fabric, retain all four upright plates 4 and adjust the spacing between the two sets of upright plates 4 to form an independent conveying channel. Move the slider 711 along the guide rail 72, determine the longitudinal position of the limit plate 78 using the scale 710, set the cutting length, and fix the position of the slider 711 using the longitudinal linear drive mechanism so that the longitudinal distance between the limit switch 71 and the cutting tool 61 matches the target length.

[0061] Reference Figure 8 The cutting process for a single wide fabric using this equipment is as follows:

[0062] The conveyor 11 transports the wide fabric to the frame 1, and the roller 2 supports the fabric for continued transport. If the front end of the fabric touches the limit switch 71 of the limit device 7 on both sides, the control operator 12 sends a signal and the conveyor 11 stops.

[0063] The cylinders 83 of the two pressure plate devices 8 synchronously drive the pressure rods 86 downward, and the helical springs 85 buffer the pressure, fixing the fabric to the tabletop 5. The gantry 62 of the cutting device 6 drives the cutter 61 to move laterally. The vertical linear drive mechanism controls the cutting depth, and the horizontal linear drive mechanism controls the lateral position of the cutter 61. The horizontal linear drive mechanism drives the cutter 61 to complete the lateral cutting along the cutting seam 51, avoiding fabric displacement.

[0064] After cutting, the cutter 61 is raised back to its original position. Cylinder 2 73 pushes the rack 74 to drive the gear 75 to rotate, the limit plate 78 flips to a horizontal state, the conveyor device 11 restarts, and the cut fabric is output through the gap of the limit plate 78. Then the limit plate 78 flips back to the vertical limit state.

[0065] The action of the pressure rod 86 of the pressure plate device 8, the flipping action of the limit plate 78, and the start / stop signal of the conveying device 11 are linked to prevent fabric accumulation.

[0066] Reference Figure 9 The process for this equipment to cut two narrow fabrics of equal length is as follows:

[0067] Two sets of vertical plates 4 form a dual channel, separating two narrow fabrics for synchronous conveying. Adjust the limiting devices 7 on both sides to the same longitudinal position to ensure that the cutting lengths of the two narrow fabrics are consistent.

[0068] When two narrow fabrics are simultaneously triggered to reach the limit switch 71, the conveyor device 11 stops. The four pressure rods 86 (two on each side) of the pressure plate device 8 press down synchronously, and the cylinder 83 independently controls to ensure uniform clamping force. The cutter 61 moves laterally to complete the dual-channel synchronous cutting.

[0069] After cutting, the pressure bar 86 and the cutter 61 are reset, and the two limit plates 78 are flipped to the horizontal state simultaneously. The two cut narrow fabrics are output through the conveying device 11. After the cut narrow fabrics are output, the two limit plates 78 are reset to the vertical limit state.

[0070] Reference Figure 10 The workflow of this equipment for cutting two narrow fabrics of unequal lengths is as follows:

[0071] The two limiting devices 7 are set to different longitudinal positions. When the narrow fabric on one side touches the limit switch 71 on the same side first, the conveying device 11 stops, and the two pressure rods 86 on the two pressure plate devices 8, which are located on the same side as the narrow fabric, press down to fix the narrow fabric. The cutter 61 of the cutting device 6 only cuts the narrow fabric on that side, while the fabric on the other side remains stationary.

[0072] After the narrow fabric on one side is cut, the limiting plate 78 on the same side as the narrow fabric flips to a horizontal position, the narrow fabric on that side is output, the conveying device 11 restarts, and the fabrics on both sides continue to be conveyed. After the narrow fabric cut on that side is output, the limiting plate 78 on that side returns to the vertical limiting position. When the fabric on the other side touches the corresponding limit switch 71, the above process is repeated to cut it individually, realizing batch cutting of fabrics of different lengths on the same device.

[0073] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
