Abstract
Description
Technical Field
[0001] This invention relates to the field of textile manufacturing technology, specifically to an automatic tensioning and shearing device for textile manufacturing. Background Technology
[0002] Textile manufacturing shearing devices are specialized equipment for achieving high-precision cutting in textile production. They integrate an automatic tensioning mechanism, a laser cutting unit, an intelligent control system, and a dust and waste collection module. Core components include a tension sensor, a laser cutting head, a positioning encoder, and a PLC main control unit. During operation, the tensioning mechanism first stabilizes the fabric tension, then the positioning component calibrates the cutting position. Subsequently, the laser head uses a high-temperature beam to achieve non-contact melting and vaporization cutting, which can complete complex shape cutting. It is suitable for a variety of textiles and is widely used in clothing customization, home textile pattern cutting, medical and automotive interior fabric processing, and other scenarios. Regular calibration of the optical path, cleaning of the cutting head lens, and maintenance of sensor accuracy are required.
[0003] Chinese patent CN218836498U discloses a laser cutting machine for textiles. It involves pulling one end of a textile fabric through a roller shaft and placing it on the upper surface of a metal track. Simultaneously, pulling a connecting rod rotates a ratchet gear, activating a motor. This, along with a linkage shaft and spur gear, drives the roller shaft and metal track to move the textile fabric, thus enabling automatic feeding of textiles of varying thicknesses. While this device is capable of feeding textiles of different thicknesses and performing basic fabric transport, it suffers from significant technical defects. In the laser cutting process, it lacks an effective limiting structure and constraint mechanism for the textile fabric, making it impossible to accurately and stably position and fix the fabric. This causes the fabric to easily shift during laser cutting, leading to problems such as exceeding cutting dimension accuracy and poor cut quality. Summary of the Invention
[0004] To solve the above technical problems, the present invention provides the following technical solution: an automatic tensioning and shearing device for textile manufacturing, comprising: A workbench is provided, with a conveyor belt rotatably connected to its inner side. The conveyor belt has evenly spaced circular holes on its side. A laser component is fixedly connected to the top of the workbench. Contact components are fixedly connected to both sides of the workbench. A collection component is fixedly connected to the middle of the workbench. Tensioning components are used to guide the fabric on the workbench. The tensioning components are located on both sides of the top of the workbench, and the bottom of the tensioning components is fixedly connected to the top of the workbench. The tensioning component includes a fixed base, the side of which is fixedly connected to the top of the worktable. Adjusting seats are fixedly connected to both sides of the top of the fixed base. Supports are fixedly connected to the sides of the two adjusting seats. A roller shaft one is rotatably connected between the two supports. A roller shaft two is rotatably connected between the two adjusting seats. A driving component one is fixedly connected to the top of the adjusting base. A lead screw is rotatably connected to the inner side of the adjusting base. The side of the lead screw is threadedly connected to the inner side of the moving frame. The output end of the driving component one is fixedly connected to the top of the lead screw. A moving frame is slidably connected to the inner side of the adjusting base. Roller shaft three is rotatably connected to both sides of the moving frame. Before laser cutting, the area of the fabric to be cut is stabilized and limited to avoid displacement or deformation of the fabric due to thermal stress or airflow disturbance when the laser beam is applied. This greatly improves the accuracy of the cutting position and reduces defects such as skewed cuts and dimensional deviations. At the same time, the multi-roller coordinated pressing can make the fabric tension distribution more uniform, further ensuring the flatness of the cut after laser melting and cutting. Preferably, the contact component includes a contact housing, the bottom of which is fixedly connected to the inner side of the workbench, an air suction machine is fixedly connected to the bottom of the inner cavity of the contact housing, a baffle is fixedly connected to the top of the air suction machine, connecting shafts are slidably connected to both sides of the inner cavity of the contact housing, a contact frame is fixedly connected to the top of the connecting shaft, the side of the contact frame is slidably connected to the inner side of the contact housing, a contact roller is rotatably connected to the inner side of the contact frame, the side of the contact roller contacts the side of the conveyor belt, and a first spring is sleeved on the connecting shaft, the bottom of the first spring is fixedly connected to the inner side of the contact housing, and the top of the first spring is fixedly connected to the bottom of the contact frame. Preferably, the collecting component includes a collecting shell, the side of which is fixedly connected to the inner side of the middle of the workbench, a mesh plate one fixedly connected to the top of the collecting shell, a dropping plate fixedly connected to the bottom of the mesh plate one, a discharging mechanism fixedly connected to the inner side of the collecting shell, the discharging mechanism being located below the dropping plate, a filtering mechanism fixedly connected to the bottom of the collecting shell, and a mesh plate two fixedly connected to the top of the filtering mechanism. This prevents the fabric roll from shifting or moving during transport due to equipment vibration or airflow disturbance, ensuring that the fabric always maintains a precise transport posture, providing a reliable guarantee for the positioning accuracy of the subsequent laser cutting process, reducing contact damage to the fabric surface, preventing cutting debris from adhering to the fabric or equipment surface again, ensuring the cleanliness and cutting accuracy of the finished fabric, purifying the processing exhaust gas, and simultaneously achieving the classified treatment of waste materials and exhaust gas. Preferably, the discharge mechanism includes a discharge cylinder, the side of which is fixedly connected to the inner side of the collection shell. The side of the discharge cylinder has evenly spaced perforations, forming a double-layer protection of the primary screen and the secondary screen, preventing debris from escaping and contaminating the filter components or drifting into the workshop. One end of the discharge cylinder is fixedly connected to a second driving component, and a spiral blade is rotatably connected to the inner side of the discharge cylinder. One end of the spiral blade is fixedly connected to the output end of the second driving component. A discharge port is provided at the end of the discharge cylinder away from the second driving component. Connecting cylinders are evenly spaced at the top of the discharge cylinder, the bottom of which is fixedly connected to the inner side of the discharge cylinder, and the top of which is fixedly connected to the inner side of the discharge plate. This spiral conveying discharge method enables continuous and stable discharge of waste materials without the need for manual cleaning, significantly reducing downtime maintenance frequency and improving equipment operational continuity. Simultaneously, the pushing action of the spiral blades prevents waste materials from accumulating and clogging inside the cylinder, ensuring long-term unobstructed discharge channels. Preferably, the filtration mechanism includes an exhaust fan, which is fixedly connected to the bottom of the collection housing, the top of the exhaust fan is fixedly connected to the bottom of the mesh plate, and interception components are evenly arranged on the side of the exhaust fan. Preferably, the interception assembly includes an exhaust pipe, the side of which is fixedly connected to the inside of an exhaust fan. One end of the exhaust pipe is fixedly connected to an interceptor plate one, and the inside of the exhaust pipe is fixedly connected to an activated carbon cylinder. The other end of the activated carbon cylinder is fixedly connected to an interceptor plate two, and the end of the exhaust pipe away from the first interceptor plate is fixedly connected to an interceptor plate three. A rotating blade is rotatably connected to the side of the third interceptor plate near the second interceptor plate, and the other end of the rotating blade is fixedly connected to a rotating shaft. The other end of the rotating shaft is rotatably connected to the side of the second interceptor plate. Telescopic rods are fixedly connected to both sides of the rotating shaft, and a scraper is fixedly connected to the other end of each telescopic rod. A second spring is sleeved on the telescopic rod. The elastic buffering effect of the spring prevents the scraper from damaging the inner wall of the exhaust pipe due to excessive contact force. One end of the second spring is fixedly connected to the scraper, and the other end is fixedly connected to the side of the rotating shaft. This achieves a step-by-step removal of pollutants from the exhaust gas while avoiding the direct emission of harmful gases and their impact on the external environment.
[0005] This invention provides an automatic tensioning and shearing device for textile manufacturing. It has the following advantages: 1. The automatic tensioning and shearing device for textile manufacturing is equipped with a tensioning component, which forms a multi-roller coordinated guiding constraint on the moving fabric roll, avoiding fabric deviation, sagging or local wrinkles during feeding, and ensuring that the fabric is fed into the conveyor belt in a flat state, laying a good material posture foundation for subsequent tensioning and cutting processes.
[0006] 2. The automatic tensioning and shearing device for textile manufacturing is equipped with contact components. The contact rollers thoroughly scrape off cutting debris, fiber impurities, and other contaminants adhering to the surface of the conveyor belt. After the suction machine is started, it generates a stable negative pressure suction force to prevent the scraped-off impurities from drifting randomly in the working area and to prevent the impurities from adhering to the conveyor belt or fabric surface again, thus avoiding any impact on the accuracy of subsequent cutting processes and the quality of the finished fabric.
[0007] 3. The automatic tensioning and shearing device for textile manufacturing is equipped with a discharge mechanism. The physical screening through the holes realizes gas-solid separation, which prevents waste from entering the filter mechanism with the waste gas and causing filter material blockage. This not only ensures the waste gas filtration efficiency, but also centrally collects solid waste, reducing the difficulty of subsequent classification and treatment.
[0008] 4. The automatic tensioning and shearing device for textile manufacturing is equipped with an interception component to remove sticky impurities remaining on the inner wall of the exhaust pipe, preventing long-term adhesion of impurities from causing the pipe diameter to narrow and the resistance to exhaust gas flow to increase, thus ensuring the smooth transport of exhaust gas.

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0012] Example 1, please refer to Figures 1-2 The present invention provides a technical solution: an automatic tensioning and shearing device for textile manufacturing, comprising: Workbench 1, conveyor belt 2 is rotatably connected to the inner side of workbench 1, and round holes are evenly opened on the side of conveyor belt 2. Laser component 3 is fixedly connected to the top of workbench 1, contact component 5 is fixedly connected to both sides of workbench 1, and collection component 6 is fixedly connected to the middle of workbench 1. Tensioning component 4 is used to guide the fabric on the workbench 1. Tensioning component 4 is located on both sides of the top of the workbench 1, and the bottom of tensioning component 4 is fixedly connected to the top of the workbench 1. Please see Figure 3The tensioning component 4 includes a fixed seat 41, the side of which is fixedly connected to the top of the worktable 1. Adjusting seats 42 are fixedly connected to both sides of the top of the fixed seat 41. Supports 43 are fixedly connected to the sides of the two adjusting seats 42. A roller 44 is rotatably connected between the two supports 43. A roller 45 is rotatably connected between the two adjusting seats 42. A driving component 46 is fixedly connected to the top of the adjusting seat 42. A lead screw 47 is rotatably connected to the inner side of the adjusting seat 42. The side of the lead screw 47 is threadedly connected to the inner side of the moving frame 48. The output end of the driving component 46 is fixedly connected to the top of the lead screw 47. The moving frame 48 is slidably connected to the inner side of the adjusting seat 42. Rollers 49 are rotatably connected to both sides of the moving frame 48. During the fabric roll feeding stage, the operator first guides the roll through roller 44 and roller 45 in sequence to complete the initial guidance. Then, the drive unit 46 is started, and its output end drives the screw 47 inside the adjusting seat 42 to rotate synchronously. The screw 47 drives the moving frame 48 to complete the corresponding height adjustment along the adjusting seat 42, thereby driving the rollers 49 on both sides of the moving frame 48 to move down to the position of contacting the fabric roll and move synchronously with the roll. During the laser cutting operation, the drive unit 46 can be restarted. Its output end drives the lead screw 47 to rotate in the opposite direction inside the adjusting seat 42, driving the moving frame 48 to move downward along the adjusting seat 42, thereby driving the roller 3 49 to cooperate with the roller 1 44 to form a bidirectional extrusion and fixation on the fabric roll. Example 2, please refer to Figure 4 Based on Embodiment 1, the present invention provides a technical solution: The contact component 5 includes a contact housing 51. The bottom of the contact housing 51 is fixedly connected to the inner side of the workbench 1. An air suction machine 52 is fixedly connected to the bottom of the inner cavity of the contact housing 51. A baffle 53 is fixedly connected to the top of the air suction machine 52. A connecting shaft 54 is slidably connected to both sides of the inner cavity of the contact housing 51. A contact frame 56 is fixedly connected to the top of the connecting shaft 54. The side of the contact frame 56 is slidably connected to the inner side of the contact housing 51. A contact roller 57 is rotatably connected to the inner side of the contact frame 56. The side of the contact roller 57 contacts the side of the conveyor belt 2. A first spring 55 is sleeved on the connecting shaft 54. The bottom of the first spring 55 is fixedly connected to the inner side of the contact housing 51. The top of the first spring 55 is fixedly connected to the bottom of the contact frame 56. When the conveyor belt 2 enters normal operation with the workbench 1, the suction machine 52 can be started simultaneously. During the rotation of the conveyor belt 2, its side surface and the side surface of the contact roller 57 maintain continuous contact and relative movement. The contact roller 57 thoroughly scrapes off the cutting debris, fiber impurities and other materials adhering to the surface of the conveyor belt 2, thus completing the cleaning work of the conveyor belt 2. After the suction machine 52 is started, it generates a stable negative pressure suction force, which can immediately adsorb the impurities scraped off by the contact roller 57 to the collection area on the top of the special baffle 53, so as to achieve centralized collection of impurities. Example 3, please refer to Figure 5 Based on Embodiment 2, the present invention provides a technical solution: The collecting component 6 includes a collecting shell 61, the side of which is fixedly connected to the inner side of the middle of the workbench 1, a mesh plate 62 is fixedly connected to the top of the collecting shell 61, a dropping plate 63 is fixedly connected to the bottom of the mesh plate 62, a discharge mechanism 64 is fixedly connected to the inner side of the collecting shell 61, the discharge mechanism 64 is located below the dropping plate 63, a filtering mechanism 65 is fixedly connected to the bottom of the collecting shell 61, and a mesh plate 66 is fixedly connected to the top of the filtering mechanism 65. When the laser component 3 performs laser cutting on the fabric roll, the fiber debris and processing exhaust gas generated by the laser cutting will be sucked into the collection shell 61 through the mesh plate 62 of the worktable 1, and then guided to the discharge mechanism 64 through the material dropping plate 63 inside the shell. For solid waste, centralized discharge and delivery can be completed directly through the discharge mechanism 64, realizing the automated collection of waste. For gaseous exhaust gas, it will continue to enter the filtration mechanism 65, and after purification treatment, it will be discharged in compliance with standards. Please see Figure 6 The discharge mechanism 64 includes a discharge cylinder 641. The side of the discharge cylinder 641 is fixedly connected to the inside of the collection shell 61. Through holes 642 are evenly provided on the side of the discharge cylinder 641. A second driving component 643 is fixedly connected to one end of the discharge cylinder 641. A spiral blade 644 is rotatably connected to the inside of the discharge cylinder 641. One end of the spiral blade 644 is fixedly connected to the output end of the second driving component 643. A discharge port 645 is provided at the end of the discharge cylinder 641 away from the second driving component 643. Connecting cylinders 646 are evenly provided on the top of the discharge cylinder 641. The bottom of the connecting cylinder 646 is fixedly connected to the inside of the discharge cylinder 641. The top of the connecting cylinder 646 is fixedly connected to the inside of the dropping plate 63. Under the negative pressure suction of the filter mechanism 65, the solid waste and gaseous exhaust gas generated by laser cutting will enter the discharge cylinder 641 simultaneously through the discharge plate 63 and the connecting cylinder 646. The waste gas and waste material are initially separated. The side wall of the discharge cylinder 641 has uniformly opened through holes 642, which allow the waste gas to pass smoothly through the through holes 642 and move downwards to enter the subsequent waste gas filtration stage. Solid waste, due to its volume and weight limitations, cannot pass through the through hole 642 and will remain in the discharge cylinder 641, achieving preliminary gas-solid separation. A second mesh plate 66 is installed below the discharge cylinder 641. Even if a small amount of fine debris passes through the hole 642 with the exhaust gas, it will be intercepted by the second mesh plate 66 and will not be able to enter the exhaust gas filtration unit. After the waste material accumulates to a certain amount in the discharge cylinder 641, the second drive component 643 is activated. Its output end drives the spiral blade 644 in the discharge cylinder 641 to rotate synchronously. The spiral blade 644 can push the waste material in the cylinder towards the discharge port 645, and finally complete the automatic discharge of the waste material through the discharge port 645. After purification, the exhaust gas will be discharged in compliance with standards. After gas-solid separation and debris interception, the exhaust gas will continue to enter the filtration mechanism 65. After purification treatment, harmful components will be removed and the exhaust gas will be discharged in compliance with standards. Please see Figure 7 The filtration mechanism 65 includes an exhaust fan 651, which is fixedly connected to the bottom of the collection housing 61, and the top of the exhaust fan 651 is fixedly connected to the bottom of the mesh plate 66. Interception components 652 are evenly arranged on the side of the exhaust fan 651. During the laser cutting of fabric, the exhaust fan 651 can be started simultaneously. The stable negative pressure suction generated during its operation will draw the solid waste and gaseous waste generated during cutting into the collection shell 61, thereby achieving centralized collection of pollutants. Solid waste will be automatically discharged through a dedicated discharge cylinder 641, achieving centralized cleaning of waste; After the waste is separated, the remaining exhaust gas flows directionally through the interception component 652 under the continuous negative pressure of the exhaust fan 651, and the harmful impurities are intercepted and filtered to achieve clean emission in compliance with standards. Please see Figure 8 The interception assembly 652 includes an exhaust pipe 6521. The side of the exhaust pipe 6521 is fixedly connected to the inside of the exhaust fan 651. One end of the exhaust pipe 6521 is fixedly connected to an interception plate 6522. An activated carbon cylinder 6523 is fixedly connected to the inside of the exhaust pipe 6521. The other end of the activated carbon cylinder 6523 is fixedly connected to an interception plate 6524. The end of the exhaust pipe 6521 away from the first interception plate 6522 is fixedly connected to an interception plate 6525. The side of the third interception plate 6525 closest to the second interception plate 6524 is rotatably connected to... A rotating blade 6526 is provided, and a rotating shaft 6527 is fixedly connected to the other end of the rotating blade 6526. The other end of the rotating shaft 6527 is rotatably connected to the side of the second interceptor plate 6524. Telescopic rods 6528 are fixedly connected to both sides of the rotating shaft 6527. A scraper 6529 is fixedly connected to the other end of the telescopic rod 6528. A second spring 6530 is sleeved on the telescopic rod 6528. One end of the second spring 6530 is fixedly connected to the scraper 6529, and the other end of the second spring 6530 is fixedly connected to the side of the rotating shaft 6527. Under the negative pressure of the exhaust fan 651, the exhaust gas that has completed the initial separation of solid and gas enters the exhaust pipe 6521 through the interceptor plate 6525. The impact force generated by the flow of exhaust gas will drive the rotating blade 6526 inside the pipe to rotate synchronously. The rotating blade 6526 drives the coaxial rotating shaft 6527 to rotate accordingly. The telescopic rods 6528 connected to both ends of the rotating shaft 6527 will synchronously drive the scraper 6529 to keep in contact with the inner wall of the exhaust pipe 6521 and rotate with the shaft to continuously scrape and clean the pipe wall. When the scraper 6529 performs pipe wall cleaning operation, if the contact pressure between the scraper 6529 and the inner wall of the exhaust pipe 6521 exceeds the preset threshold. The telescopic rod 6528 will automatically retract and simultaneously stretch the second spring 6530 sleeved on the rod body, causing the scraper 6529 to retract adaptively. The exhaust gas that has completed pipe wall cleaning will continue to flow forward and enter the activated carbon cylinder 6523 through the second interceptor plate 6524. Under the adsorption of activated carbon, the harmful organic components and odor molecules in the exhaust gas are fully intercepted and purified. The purified exhaust gas is then discharged through the first interceptor plate 6522.
[0013] Specific workflow: The operator first clamps the fabric roll to the feeding end through the tensioning component 4 to complete the initial fabric feeding and guiding positioning; The conveyor belt 2 drives the fabric roll to be continuously conveyed forward. During this process, the tensioning component 4 applies adaptive tension to the fabric in real time to ensure that the fabric maintains a stable tension state that is flat and wrinkle-free throughout the process. When the fabric travels to the cutting area of the laser component 3, the high-precision encoder integrated into the conveying path completes the accurate measurement of the fabric's travel length, and the photoelectric sensor that is activated simultaneously performs secondary calibration on the fabric edge or the preset positioning mark. Once the fabric has been confirmed to have reached the preset cutting position, the control system immediately triggers the laser cutting head to emit a high-energy laser beam, which completes the precise cutting of the fabric in a non-contact melting and cutting manner. At the same time, the matching smoke and debris collection component 6 is activated simultaneously to instantly remove the smoke and fiber debris generated during the cutting process, ensuring a clean processing environment and the quality of the cutting edge. During the entire operation of the conveyor belt 2, it moves synchronously with the contact component 5 to ensure that the conveyor belt 2 operates stably for a long time and that no pollutants contaminate the fabric.
