Description

Technical Field

[0001] This invention relates to the field of edge trimming machine technology, specifically an edge trimming machine with self-adjusting tension. Background Technology

[0002] Fabric edge trimming machines are core supporting equipment in the textile industry's post-processing stage. During the textile production process, after mechanical spinning and weaving, the edges of the fabrics often have rough edges, frayed edges, and inconsistent widths, directly affecting the overall quality of the fabric and its suitability for subsequent processing. To ensure the overall aesthetics of the textiles, the edges need to be trimmed and removed. Edge trimming is a necessary step before fabric shaping, dyeing, lamination, and garment sewing. Fabric edge trimming machines can neatly trim the edges of the fabric, standardize the fabric width, and keep the edges flat and tight.

[0003] Existing fabric trimming equipment lacks the function of cutting off rough edges and frayed edges located on the upper and lower surfaces of the fabric to the edge of the fabric before cutting them off, and also lacks the function of cleaning the fabric surface before winding. Summary of the Invention

[0004] The purpose of this invention is to provide a trimming machine with self-adjusting tension to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The edge trimming machine includes a frame, on which an unwinding roller, a fixed roller, and a shearing table are sequentially mounted. A heating roller and a front roller are respectively mounted at both ends of the shearing table. A humidifying roller is slidably mounted between the heating roller and the fixed roller. A rear roller and a take-up roller are mounted below the shearing table. A pressing roller is slidably mounted between the front roller and the rear roller. An edge-straightening assembly is provided between the unwinding roller and the fixed roller. A shearing assembly is provided on the frame above the shearing table. An edge-tightening assembly is provided on one side of the shearing assembly. A dust collection assembly is provided between the rear roller and the take-up roller. The shearing assembly includes a slide table, a crossbeam, a slider, a vibrating knife, and a pressing element; Both sides of the frame above the shearing table have sliding tables, each with a lifting rod. A crossbeam is mounted on the lifting rod, and sliders are symmetrically slidably mounted on the crossbeam. A vibrating knife and an edge-pressing component are installed at the bottom of each slider. When trimming the fabric edge, the fabric is first guided through the unwinding roller, then through the heating roller to the shearing table, and finally through the rear roller to the take-up roller. During this process, the edge-aligning component gathers any lint adhering to the bottom or surface of the fabric to the edge, preventing bulges caused by lint accumulation during shearing on the shearing table. Subsequently, the fabric is ironed to a certain extent by the humidifying roller and the heating roller. The effect is that, by moving the humidifying roller up and down, the tension of the fabric at the front end can be controlled, and then the tension at the rear end can be controlled by the pressing roller, so as to segment the tension of a piece of fabric and improve the response efficiency of tension control. By adjusting the distance between the two sliders, the vibrating knife and the edge of the fabric are appropriately spaced. At this time, the lowering beam makes the vibrating knife contact the fabric and cut the edge. During the descent, the edge pressing component contacts the fabric before the vibrating knife and presses the fabric with the shearing table. Since the fabric is moving forward, the excess fabric cut by the edge gathering component is collected.

[0006] As a preferred technical solution, the edge-mounted assembly includes a mounting base, a drive motor, a rotating shaft, threads, a mounting block, a cantilever beam, a fixing plate, an electric telescopic rod, and a guide plate; A mounting base is symmetrically installed on the frame between the unwinding roll and the stationary roll. A drive motor is mounted on each mounting base, and a rotating shaft is installed at the output end of the drive motor. Both ends of the rotating shaft are threaded with opposite directions of rotation. Mounting blocks are symmetrically slidably mounted on the rotating shaft, and a cantilever beam is mounted on each mounting block. A fixed plate is mounted on the end of the cantilever beam furthest from the mounting block. Two electric telescopic rods are mounted on the side of the fixed plate furthest from the mounting block. The actuator ends of the two electric telescopic rods pass through the fixed plate, and guide plates are rotatably mounted on the actuator ends of the two electric telescopic rods. When the weaving... When the fabric is being edge-trimmed, the drive motor rotates the rotating shaft, causing the two mounting blocks to move closer together. This, in turn, brings the two cantilever beams closer to the upper and lower surfaces of the fabric until the guide plate contacts the fabric. At this point, the angle and distance between the guide plate and the fabric edge are controlled by extending the two electric telescopic rods. Ultimately, when the fabric edge passes the guide plate, the nap on it is strongly shaped to the edge. At the same time, under the action of the fixed roller, even if the humidifying roller presses down to tension the fabric, it will not affect the horizontality of the fabric between the unwinding roller and the fixed roller, providing a stable environment for edge trimming.

[0007] As a preferred technical solution, the edge-following assembly also includes a driving pulley, a driven pulley, a starter motor, an adsorption plate, and an electric push rod; A starter motor is installed on the side wall of the frame at both ends of the fixed roller. A driven pulley is installed at the power input end of the starter motor. A drive pulley is installed at both ends of the fixed roller. A belt is fitted between the drive pulley and the driven pulley. An electric push rod is installed on the cantilever beam near the drive motor. An adsorption plate is installed at the actuation end of the electric push rod. Conductive plates are installed on both the guide plate and the adsorption plate. The positive and negative poles of the starter motor are connected to the two conductive plates respectively. When the fixed roller rotates, the starter motor is driven by the drive pulley and the driven pulley, so that the conductive plates on the guide plate and the adsorption plate are charged with different charges. When the guide plate contacts the fluff, the fluff is charged. The charged fluff is more likely to move towards the side under the traction of the adsorption plate with opposite charges.

[0008] As a preferred technical solution, the dust collection assembly includes a slide rail, a housing, a guide sleeve, a slide rod, a contact, a rotary motor, a drive shaft, a dial, an adjusting component, and a connecting rod; A slide rail is installed at the bottom of the frame between the rear roller and the take-up roller. A housing is slidably mounted on the slide rail, and a guide sleeve is installed on the top of the housing. The guide sleeve extends through the top of the housing, and a slide rod is slidably mounted inside the guide sleeve. A contact head is installed at the protruding end of the slide rod. A rotary motor is installed on one side of the housing. The output shaft of the rotary motor extends through the side wall of the housing, and a drive shaft is installed at the end of the output shaft. A dial is mounted on the drive shaft, and an adjustment component is set on the dial. A connecting rod is rotatably mounted on the actuating end of the adjustment component. The end of the connecting rod is rotatably connected to the slide rod. By driving the rotary motor, the drive shaft drives the dial to rotate, which in turn drives the slide rod to slide back and forth within the guide sleeve through the connecting rod. This causes the contact head to repeatedly touch the fabric, creating fluctuations, thereby reducing the lint and dust adhering to the fabric and achieving a cleaning effect.

[0009] As a preferred technical solution, the adjusting components include a slide, a mounting hole, a screw, an adjusting block, a mounting groove, an adjusting motor, and a gear set; The dial has a groove and a mounting hole, which are concentric with the dial. A screw is rotatably mounted in the groove, with one end of the screw penetrating the side wall of the mounting hole. A mounting groove is formed on the contact surface between the drive shaft and the dial, and an adjusting motor is installed in the mounting groove. The output shaft of the adjusting motor meshes with the screw through a gear set. By adjusting the forward and reverse rotation of the motor, the rotation direction of the screw is controlled, further controlling the distance from the adjusting block to the center of the dial, thereby controlling the reciprocating speed of the slide rod in the guide sleeve, and thus adjusting the contact frequency between the contact head and the cloth to achieve control of the cleaning effect.

[0010] As a preferred technical solution, a negative pressure machine is installed on one side of the frame, and a dust collection head is rotatably installed on one side of the slide rail. The dust collection head is connected to the negative pressure machine through a pipe.

[0011] As a preferred technical solution, the edge-trimming assembly includes a passageway, an exit roller, and a pressure roller; Both sides of the frame are equipped with lead-out rollers and pressure rollers near the shearing components, and passageways are opened on the side wall of the frame near the pressure rollers.

[0012] As a preferred technical solution, the bottom surface of the passageway is lower than the working surface of the shearing table.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. When trimming the edge of the fabric, this application uses an edge-guiding component to gather the fuzz attached to the bottom or surface of the fabric to the edge, so that the fabric will not bulge due to the accumulation of fuzz when it is cut on the shearing table. Then, the humidifying roller and the heating roller achieve a certain ironing effect. At the same time, by moving the humidifying roller up and down, the tension of the fabric at the front end can be controlled. Then, the tension at the rear end is controlled by the pressing roller, so as to segment the tension of a piece of fabric and improve the response efficiency of tension control.

[0014] 2. This application uses a drive motor to rotate the rotating shaft, causing the two cantilever beams to approach the upper and lower surfaces of the fabric until the guide plate contacts the fabric. At this point, the angle and distance between the guide plate and the fabric edge are controlled by controlling the extension length of the two electric telescopic rods. Ultimately, when the fabric edge passes the guide plate, the pile on it is strongly shaped to the fabric edge. At the same time, the starter motor is running, so that the conductive sheets on the guide plate and the adsorption plate are charged with different charges. When the guide plate contacts the pile, the pile is charged, and the charged pile is more easily pulled towards the edge under the traction of the adsorption plate with opposite charges.

[0015] 3. This application uses a drive motor to rotate the drive shaft and rotate the dial, which in turn drives the slide rod to slide back and forth in the guide sleeve via a connecting rod. This causes the contact point to repeatedly touch the fabric and create fluctuations, thereby reducing the lint and dust adhering to the fabric and achieving a cleaning effect. By adjusting the forward and reverse rotation of the motor to control the rotation direction of the screw, the distance from the adjusting block to the center of the dial is further controlled, thereby controlling the reciprocating speed of the slide rod in the guide sleeve.

[0018] 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.

[0019] Example: Figures 1-5As shown, the present invention provides a technical solution for an edge trimming machine with self-adjusting tension. The edge trimming machine includes a frame 1, on which an unwinding roller 101, a fixed roller 102 and a shearing table 103 are sequentially mounted. A heating roller 104 and a front roller 105 are respectively mounted at both ends of the shearing table 103. A humidifying roller 106 is slidably mounted between the heating roller 104 and the fixed roller 102. A rear roller 107 and a take-up roller 108 are mounted below the shearing table 103. A pressing roller 109 is slidably mounted between the front roller 105 and the rear roller 107. An edge-straightening component 2 is provided between the unwinding roller 101 and the fixed roller 102. A shearing component 3 is provided on the frame 1 above the shearing table 103. An edge-collecting component 4 is provided on one side of the shearing component 3. A dust collection component 5 is provided between the rear roller 107 and the take-up roller 108. The shearing assembly 3 includes a slide table 301, a crossbeam 302, a slider 303, a vibrating knife 304, and a pressing element 305; Slide tables 301 are slidably mounted on both sides of the frame 1 above the shearing table 103. Lifting rods are mounted on the slide tables 301, and crossbeams 302 are mounted on the lifting rods. Sliding blocks 303 are symmetrically mounted on the crossbeams 302. Vibrating blades 304 and edge-pressing components 305 are mounted at the bottom of the sliding blocks 303. When trimming the fabric edge, the fabric is first led out through the unwinding roller 101, passes through the heating roller 104, and reaches the shearing table 103. Then, it is led to the take-up roller 108 through the rear roller 107. During this process, the edge-aligning component 2 organizes the lint attached to the bottom or surface of the fabric to the edge, preventing bulges caused by lint accumulation during shearing on the shearing table 103. The fabric then passes through the humidifying roller 106. The heating roller 104 provides a certain ironing effect. At the same time, the humidifying roller 106 can control the tension of the fabric at the front end by moving up and down. Then, the tension at the rear end is controlled by the pressing roller 109, so that the tension of a piece of fabric can be segmented, improving the response efficiency of tension control. By adjusting the distance between the two sliders 303, the vibrating knife 304 is positioned at a suitable distance from the fabric edge. At this time, the descending beam 302 causes the vibrating knife 304 to contact the fabric and cut the edge. During the descent, the edge pressing component 305 contacts the fabric before the vibrating knife 304 and presses the fabric against the shearing table 103. Since the fabric is moving forward, the excess fabric is collected by the edge gathering component 4.

[0020] As shown in the figure, the side-mounted component 2 includes a mounting base 201, a drive motor 202, a rotating shaft 203, a thread 2031, a mounting block 204, a cantilever beam 205, a fixing plate 206, an electric telescopic rod 207, and a guide plate 208. A mounting base 201 is symmetrically mounted on the frame 1 between the unwinding roller 101 and the fixed roller 102. A drive motor 202 is mounted on the mounting base 201. A rotating shaft 203 is mounted on the output end of the drive motor 202. Both ends of the rotating shaft 203 are threaded 2031 with opposite directions of rotation. Mounting blocks 204 are symmetrically slidably mounted on the rotating shaft 203. A cantilever beam 205 is mounted on the mounting block 204. A fixing plate 206 is mounted on the end of the cantilever beam 205 away from the mounting block 204. Two electric telescopic rods 207 are mounted on the side of the fixing plate 206 away from the mounting block 204. The actuating ends of the two electric telescopic rods 207 penetrate the fixing plate 206. The actuator is rotatably mounted with a guide plate 208. When trimming the fabric edge, the drive motor 202 drives the rotating shaft 203 to rotate, thereby bringing the two mounting blocks 204 closer together, and then bringing the two cantilever beams 205 closer to the upper and lower surfaces of the fabric, until the guide plate 208 contacts the fabric. At this time, the angle and distance between the guide plate 208 and the fabric edge are controlled by controlling the extension length of the two electric telescopic rods 207. Finally, when the fabric edge passes through the guide plate 208, the pile on it is strongly shaped to the fabric edge. At the same time, under the action of the fixed roller 102, even if the humidifying roller 106 presses down to tension the fabric, it will not affect the horizontality of the fabric between the unwinding roller 101 and the fixed roller 102, providing a stable environment for edge trimming.

[0021] The edge-following assembly 2 also includes a drive pulley 209, a driven pulley 210, a starter motor 211, an adsorption plate 212, and an electric push rod 213; A starter motor 211 is installed on the side wall of the frame 1 at both ends of the fixed roller 102. A driven pulley 210 is installed at the power input end of the starter motor 211. A drive pulley 209 is installed at both ends of the fixed roller 102. A belt is sleeved between the drive pulley 209 and the driven pulley 210. An electric push rod 213 is installed on the cantilever beam 205 near the drive motor 202. An adsorption plate 212 is installed at the actuating end of the electric push rod 213. A guide plate 208 and an adsorption plate 212 are also installed. Each of the rollers is equipped with conductive plates. The positive and negative poles of the starter motor 211 are connected to the two conductive plates respectively. When the fixed roller 102 rotates, the starter motor 211 is driven to run through the driving pulley 209 and the driven pulley 210, so that the conductive plates on the guide plate 208 and the adsorption plate 212 are charged with different charges. When the guide plate 208 contacts the fluff, the fluff is charged. The charged fluff is more likely to move towards the side under the traction of the adsorption plate 212 with opposite charges.

[0022] As shown in the figure, the dust collection assembly 5 includes a slide rail 501, a housing 502, a guide sleeve 503, a slide rod 504, a contact 505, a rotary motor 506, a drive shaft 507, a dial 508, an adjusting component 509, and a connecting rod 510. A slide rail 501 is installed at the bottom of the frame 1 between the rear roller 107 and the take-up roller 108. A housing 502 is slidably mounted on the slide rail 501. A guide sleeve 503 is installed on the top of the housing 502, penetrating the top of the housing 502. A slide rod 504 is slidably mounted inside the guide sleeve 503. A contact head 505 is installed at the protruding end of the slide rod 504. A rotary motor 506 is installed on one side of the housing 502. The output shaft of the rotary motor 506 penetrates the side wall of the housing 502, and a drive shaft 50 is installed at the end of the output shaft of the rotary motor 506. 7. A dial 508 is mounted on the drive shaft 507. An adjustment component 509 is provided on the dial 508. A connecting rod 510 is rotatably mounted on the actuating end of the adjustment component 509. The end of the connecting rod 510 is rotatably connected to the slide rod 504. By driving the rotary motor 506, the drive shaft 507 drives the dial 508 to rotate. This causes the slide rod 504 to slide back and forth in the guide sleeve 503 through the connecting rod 510. This causes the contact 505 to reciprocate and touch the fabric, creating fluctuations. This reduces the lint and dust adhering to the fabric, achieving a cleaning effect.

[0023] The adjusting component 509 also includes a slide 5091, a mounting hole 5092, a screw 5093, an adjusting block 5094, a mounting groove 5095, an adjusting motor 5096, and a gear set 5097; The dial 508 has a sliding groove 5091 and a mounting hole 5092. The mounting hole 5092 is concentric with the dial 508. A screw 5093 is rotatably mounted in the sliding groove 5091. One end of the screw 5093 passes through the side wall of the mounting hole 5092. A mounting groove 5095 is provided on the contact surface between the drive shaft 507 and the dial 508. An adjusting motor 5096 is installed in the mounting groove 5095. The output shaft of the adjusting motor 5096 meshes with the screw 5093 through a gear set 5097. By adjusting the forward and reverse rotation of the adjusting motor 5096, the rotation direction of the screw 5093 is controlled, which further controls the distance from the adjusting block 5094 to the center of the dial 508, thereby controlling the reciprocating speed of the slide rod 504 in the guide sleeve 503, and thus adjusting the contact frequency between the contact head 505 and the cloth to achieve control of the cleaning effect.

[0024] A negative pressure machine 6 is installed on one side of the frame 1, and a dust collection head 601 is rotatably installed on one side of the slide rail 501. The dust collection head 601 is connected to the negative pressure machine 6 through a pipe.

[0025] The edge-trimming assembly 4 includes a passageway 401, an exit roller 402, and a pressure roller 403; Both sides of the frame 1 are equipped with lead-out rollers 402 and pressure rollers 403 near the shearing assembly 3. A passageway 401 is opened on the side wall of the frame 1 near the pressure roller 403.

[0026] The bottom surface of passageway 401 is lower than the working surface of shearing table 103.

[0027] Working principle of the invention: When trimming the fabric edges, the fabric is first drawn out through the unwind roller 101, passes through the heating roller 104, and reaches the shearing table 103. Then, it is guided to the take-up roller 108 through the rear roller 107. During this process, the edge-aligning assembly 2 organizes the lint attached to the bottom or surface of the fabric to the edge, preventing bulges caused by lint accumulation when the fabric is cut on the shearing table 103. Subsequently, the humidifying roller 106 and the heating roller 104 provide a certain ironing effect. At the same time, the up-and-down movement of the humidifying roller 106 controls the fabric tension at the front end. Then, the tension force at the rear end is controlled by the pressure roller 109 to achieve segmented tension of a piece of fabric, thereby improving the response efficiency of tension control. By adjusting the distance between the two sliders 303, the vibrating knife 304 is positioned at a suitable distance from the fabric edge. At this time, the descending beam 302 causes the vibrating knife 304 to contact the fabric and cut the edge. During the descent, the edge pressing component 305 contacts the fabric before the vibrating knife 304 and presses the fabric against the shearing table 103. Since the fabric is moving forward, the excess fabric is collected by the edge gathering component 4.

[0028] When trimming the fabric edge, the drive motor 202 drives the rotating shaft 203 to rotate, thereby bringing the two mounting blocks 204 closer together, and then bringing the two cantilever beams 205 closer to the upper and lower surfaces of the fabric, until the guide plate 208 contacts the fabric. At this time, the angle and distance between the guide plate 208 and the fabric edge are controlled by controlling the extension length of the two electric telescopic rods 207. Finally, when the fabric edge passes through the guide plate 208, the pile on it is strongly shaped to the fabric edge. At the same time, under the action of the fixed roller 102, even if the humidifying roller 106 presses down to tension the fabric, it will not affect the horizontality of the fabric between the unwinding roller 101 and the fixed roller 102, providing a stable environment for trimming the edge.

[0029] When the fixed roller 102 rotates, the motor 211 is driven by the driving pulley 209 and the driven pulley 210, so that the conductive sheets on the guide plate 208 and the adsorption plate 212 are charged with different charges. When the guide plate 208 contacts the fluff, the fluff is charged, and the charged fluff is more likely to move towards the side under the traction of the adsorption plate 212 with opposite charges.

[0030] By driving the rotary motor 506, the drive shaft 507 drives the dial 508 to rotate, which in turn drives the slide bar 504 to slide back and forth in the guide sleeve 503 via the connecting rod 510. This causes the contact 505 to repeatedly touch the fabric, creating fluctuations, thereby reducing the lint and dust attached to the fabric and achieving a cleaning effect.

[0031] By adjusting the forward and reverse rotation of the motor 5096 to control the rotation direction of the screw 5093, the distance between the adjusting block 5094 and the center of the dial 508 is further controlled, thereby controlling the reciprocating speed of the slide bar 504 within the guide sleeve 503, and thus adjusting the contact frequency between the contact 505 and the cloth, thereby achieving control over the cleaning effect.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
