Description

Technical Field

[0001] This invention relates to the field of garment processing technology, specifically to a fabric positioning device for garment processing. Background Technology

[0002] In the garment processing and production process, the positioning of the fabric is a key preliminary step in the cutting and sewing process, which directly affects the dimensional accuracy and appearance quality of the finished garment. Therefore, a positioning device is needed to fix the fabric before processing.

[0003] Most existing fabric positioning devices only have simple pressing and positioning functions and cannot simultaneously achieve automatic fabric flattening and wrinkle elimination. Manual assistance is still required for smoothing. At the same time, lint and debris generated during processing are easily scattered on the table. The lack of an automatic dust collection structure linked with the positioning mechanism not only pollutes the processing environment but also adheres to the fabric surface, affecting the quality of the finished product. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fabric positioning device for garment processing. This solves the problem that most existing fabric positioning devices only have simple pressing and positioning functions and cannot simultaneously achieve automatic fabric flattening and wrinkle elimination, still requiring manual assistance to smooth the fabric. At the same time, lint and debris generated during processing are easily scattered on the work surface, and there is a lack of an automatic dust collection structure linked with the positioning mechanism, which not only pollutes the processing environment but also adheres to the fabric surface, affecting the quality of the finished product.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fabric positioning device for garment processing, comprising a base, a support plate fixedly connected to one side of the base, a positioning component provided on the top of the support plate, the positioning component comprising a frame, the bottom of the frame fixedly connected to the top of the support plate, a movable block slidably connected inside the frame, fixed seats fixedly connected to both sides of the movable block, a swing rod hinged inside the fixed seat, a limit rod installed at the end of the swing rod away from the fixed seat, a pressing roller sleeved on the outer wall of the limit rod, a spring fixedly connected to the side of the movable block and the swing rod opposite to each other, through holes evenly distributed on the top of the base, a movable rod slidably connected within the through holes of the base, a placement plate fixedly connected to the top of the movable rod, a spring fixedly connected to the side of the base and the placement plate opposite to each other, an auxiliary leveling component provided on one side of the base, and a dust suction component provided at the bottom of the placement plate.

[0006] By adopting the above technical solution, the motor drives the lead screw to rotate. Under the guidance and limitation of the guide rod, the movable block moves the moving block downward. The moving block moves the swing rods, limit rods, pressing rollers and long plate on both sides downward as a whole. When the pressing rollers move down to contact the fabric surface, as the pressing rollers continue to move down, the movable rods are forced to move down along the through hole of the base. The second spring is compressed, and the placement plate and the second electrode block at the bottom move down synchronously. When the second electrode block moves down to contact the first electrode block, the indicator light is turned on and illuminates, indicating that the fabric has been fully pressed and reached the optimal pressing state. The placement plate stops moving down. At this time, the moving block continues to move down. Under the limitation constraint of the limit slide, the two swing rods drive the two limit rods to move away from each other, thereby driving the two pressing rollers to expand outward to both sides synchronously, spreading and smoothing the fabric laterally outward, effectively eliminating fabric wrinkles, and realizing the fabric pressing and positioning and lateral flattening operation.

[0007] Preferably, a motor is installed at the bottom of the support plate, and a lead screw is fixedly connected to the output end of the motor. The lead screw is rotatably connected to the frame, and a movable block is threadedly connected to the outer wall of the lead screw. One side of the movable block is fixedly connected to one side of the moving block. A guide rod is fixedly connected inside the frame, and a through hole is opened in the middle of the moving block. The outer wall of the guide rod is slidably connected to the through hole.

[0008] Preferably, the auxiliary leveling component includes two fixing ears 1, one side of which is symmetrically fixedly connected to one side of the base. A rod hole is opened in the middle of the two fixing ears 1, and a lifting rod is slidably connected in the rod hole of the fixing ears 1. The top of each of the two lifting rods is fixedly connected to a fixing ear 2. A long plate is fixedly connected to one side of the two fixing ears 2. A limiting groove is opened in the middle of the long plate, and the outer wall of the limiting rod is slidably connected in the limiting groove.

[0009] Preferably, a first electrode block is installed on the top of the base, a second electrode block is installed on the bottom of the placement plate, an installation plate is fixedly connected to the outer wall of the base, an indicator light is provided on the top of the installation plate, and the indicator light, the second electrode block and the first electrode block are electrically connected.

[0010] Preferably, the dust collection assembly includes a dust collection box, the top of which is fixedly connected to the bottom of the base, a dust collection hood is fixedly connected to the bottom of the long plate, a dust collection hose is fixedly connected between the dust collection hood and the dust collection box, an outer sleeve is fixedly connected to the middle of the dust collection hose, and the bottom of the outer sleeve is fixedly connected to the top of the base.

[0011] Preferably, a lifting column is slidably connected inside the outer sleeve, the lifting column has a communicating hole inside, and the top of the lifting column is fixedly connected to the bottom of the placement plate.

[0012] Preferably, a dust collection pump is installed on one side of the dust collection box, an air extraction pipe is fixedly connected to the input port of the dust collection pump, one end of the air extraction pipe is fixedly connected to one side of the dust collection box, and an air outlet pipe is fixedly connected to the output port of the dust collection pump.

[0013] Preferably, the dust collection box is provided with an arc-shaped filter screen inside, and the arc-shaped filter screen is arranged around the port of the air extraction pipe.

[0014] Preferably, the outer wall of the dust collection box is provided with a discharge port, and the outer wall of the dust collection box is symmetrically and fixedly connected with limit slide rails.

[0015] Preferably, the two limiting slide rails are located on both sides of the discharge port, and a sealing plate is slidably connected inside the two limiting slide rails.

[0016] Working principle: In use, first lay the fabric flat on the placement plate, then start the motor to drive the lead screw to rotate. Under the guidance and limit of the guide rod, the movable block drives the moving block to move steadily down along the frame. The moving block drives the swing rods, limit rods, pressing rollers and long plate on both sides to move down as a whole. When the pressing roller moves down to contact the surface of the fabric, as the pressing roller continues to move down, it forces the movable rod to move down along the through hole of the base. The second spring is compressed, and the placement plate and the second electrode block at the bottom move down synchronously. When the second electrode block moves down to contact the first electrode block, the indicator light circuit is turned on and illuminated, indicating that the fabric has been fully pressed and reached the optimal pressing state. The placement plate stops moving down. At this time, the moving block continues to move down. Under the limit constraint of the limit slide, the two swing rods drive the two limit rods to move away from each other, thereby driving the two pressing rollers to expand outward to both sides synchronously, spreading and smoothing the fabric laterally outward, completing the positioning and flattening process.

[0017] As the placement plate moves down, the lifting column at its bottom moves down simultaneously. After the fabric is pressed, flattened, and positioned, the lifting column moves down the internal connecting hole to precisely connect with the dust collection hose. With the cooperation of the dust pump, a negative pressure is formed in the dust collection box, which draws in the lint and debris generated during the processing through the dust hood and into the dust collection box along the dust collection hose, where the lint and debris are collected.

[0018] After processing is completed, the motor reverses and drives the moving block to move upward. Spring 1 pulls the swing arm to reset, the two pressing rollers move closer to each other, and at the same time, spring 2 rebounds, lifting the placement plate. The second electrode block separates from the first electrode block, the indicator light goes out, the lifting column moves upward to make the connecting hole and the dust suction hose misalign, the dust suction passage closes automatically, and the device returns to its initial state, making it convenient for the next material placement operation.

[0019] This invention provides a fabric positioning device for garment processing. It has the following beneficial effects:

[0020] 1. This invention utilizes a motor to drive a lead screw to rotate. Under the guidance and limitation of the guide rod, the movable block moves the moving block downwards. The moving block then moves the swing rods, limit rods, pressing rollers, and long plate on both sides downwards as a whole. When the pressing rollers reach contact with the fabric surface, the movable rods are forced to move downwards along the through hole of the base as the pressing rollers continue to move downwards. The second spring is compressed, and the placement plate and the second electrode block at the bottom move downwards synchronously. When the second electrode block reaches contact with the first electrode block, the indicator light is turned on and illuminates, indicating that the fabric has been fully pressed and reached the optimal pressing state. The placement plate stops moving downwards, and the moving block continues to move downwards. Under the limiting constraint of the limiting groove, the two swing rods move the two limit rods away from each other, thereby driving the two pressing rollers to expand outwards to both sides synchronously, spreading and smoothing the fabric laterally outwards, effectively eliminating fabric wrinkles, and realizing the fabric pressing and positioning and lateral flattening operation.

[0021] 2. In this invention, when the placement plate moves down, the lifting column at its bottom moves down synchronously along the inner wall of the outer sleeve. After the fabric is pressed, flattened, and positioned, the lifting column moves down the connecting hole inside to precisely connect with the vacuum hose. With the cooperation of the vacuum pump, a negative pressure is formed in the dust collection box. The lint and debris generated during the processing are efficiently sucked in by the vacuum hood under the action of negative pressure and transported to the dust collection box through the vacuum hose. This allows for the cleaning and collection of lint and debris generated during the processing, keeping the work surface clean and improving the processing environment and fabric quality.

[0022] 3. After processing, the present invention reverses the motor to move the moving block upward, the first spring pulls the swing arm to reset, the two pressing rollers move closer to each other, and at the same time the second spring rebounds to lift the placement plate, the second electrode block separates from the first electrode block, the indicator light goes out, the lifting column moves upward to make the connecting hole and the dust suction hose misalign, the dust suction passage is automatically closed, the device returns to the initial state, and it is convenient to carry out the next material positioning operation.

[0023] 4. This invention first presses the fabric, then expands and flattens it outwards to both sides simultaneously. After pressing and flattening, it automatically starts the dust extraction process. The entire process is achieved with a purely mechanical structure to achieve precise linkage. It is stable and reliable in operation, has a low failure rate, low mechanical wear, and a long service life. At the same time, it completes the pressing and positioning of the fabric, horizontal flattening, and debris removal, eliminating the need for manual smoothing and manual dust removal, and greatly improving the efficiency of garment processing.

[0035] The technical solution of the present invention will now be clearly and completely described 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.

[0036] Please see the appendix Figure 1 -Appendix Figure 5This invention provides a fabric positioning device for garment processing, including a base 1. A support plate 2 is fixedly connected to one side of the base 1. A positioning component is provided on the top of the support plate 2. The positioning component includes a frame 3. The bottom of the frame 3 is fixedly connected to the top of the support plate 2. A movable block 301 is slidably connected inside the frame 3. Fixed seats 302 are fixedly connected to both sides of the movable block 301. A swing rod 303 is hinged inside the fixed seat 302. A limiting device is installed at the end of the swing rod 303 away from the fixed seat 302. Positioning rod 305, with pressing roller 306 sleeved on the outer wall of positioning rod 305, spring 304 fixedly connected to the opposite side of moving block 301 and swing rod 303, through holes evenly opened on the top of base 1, movable rod 311 slidably connected in the through holes of base 1, placement plate 313 fixedly connected to the top of movable rod 311, spring 312 fixedly connected to the opposite side of base 1 and placement plate 313, auxiliary leveling component provided on one side of base 1, and dust suction component provided at the bottom of placement plate 313.

[0037] Specifically, when pressing and positioning the fabric, the fabric is first laid flat on the placement plate 313. Then, the motor 308 is started, driving the lead screw 309 to rotate. Under the guidance and limitation of the guide rod 307, the movable block 310 drives the moving block 301 to move steadily downward along the frame 3. The moving block 301 drives the swing rods 303, limit rods 305, pressing rollers 306 and long plate 403 on both sides to move downward as a whole. When the pressing roller 306 moves down to contact the fabric surface, as the pressing roller 306 continues to move downward, it forces the movable rod 311 to move down along the through hole of the base 1. The second spring 312 is compressed, and the placement plate 313 and the second electrode block 314 at the bottom are compressed. The second electrode block 314 moves down synchronously until it contacts the first electrode block 315. At this point, the indicator light 317 is energized and illuminates, indicating that the fabric has been fully pressed and reached the optimal pressing state. The placement plate 313 stops moving down, and the moving block 301 continues to move down. Under the limiting constraint of the limiting slide 404, the two swing rods 303 drive the two limiting rods 305 to move away from each other, thereby driving the two pressing rollers 306 to expand outward to both sides synchronously, spreading and smoothing the fabric laterally outward, effectively eliminating fabric wrinkles, and realizing the fabric pressing and positioning and lateral flattening operation; by setting a dust collection component, the lint and debris generated during the processing can be cleaned and collected.

[0038] Please see the appendix Figure 2 -Appendix Figure 5A motor 308 is installed at the bottom of the support plate 2. A lead screw 309 is fixedly connected to the output end of the motor 308. The lead screw 309 is rotatably connected inside the frame 3. A movable block 310 is threadedly connected to the outer wall of the lead screw 309. One side of the movable block 310 is fixedly connected to one side of the moving block 301. A guide rod 307 is fixedly connected inside the frame 3. A through hole is opened in the middle of the moving block 301. The outer wall of the guide rod 307 is slidably connected inside the through hole. A first electrode block 315 is installed at the top of the base 1. A second electrode block 314 is installed at the bottom of the placement plate 313. An installation plate 316 is fixedly connected to the outer wall of the base 1. An indicator light 317 is set at the top of the installation plate 316. The indicator light 317, the second electrode block 314 and the first electrode block 315 are electrically connected.

[0039] Specifically, the motor 308 is started, which drives the lead screw 309 to rotate. The lead screw 309 drives the movable block 310 to move downward in the vertical direction through the thread transmission. The movable block 310 then drives the moving block 301 to move downward in sync. The guide rod 307 passes through the through hole of the moving block 301 to limit and guide the moving block 301, so that it only makes vertical linear movement, effectively avoiding deflection and jamming, and ensuring that the pressing roller 306 presses down and flattens the fabric accurately, stably and smoothly.

[0040] When the pressing roller 306 contacts the fabric and continues to press down, the placement plate 313 is pressed down, which in turn drives the movable rod 311 to move down along the through hole of the base 1. The second spring 312 is compressed, and the placement plate 313 and the second electrode block 314 at the bottom move down synchronously until the second electrode block 314 moves down to contact the first electrode block 315. Then the indicator light 317 is powered on and becomes bright, indicating that the fabric has been fully pressed and reached the optimal pressing state.

[0041] Please see the appendix Figure 1 -Appendix Figure 3 The auxiliary leveling component includes two fixing ears 4. One side of each fixing ear 4 is symmetrically fixed to one side of the base 1. A rod hole is provided in the middle of each fixing ear 4. A lifting rod 401 is slidably connected in the rod hole of the fixing ear 4. The top of each lifting rod 401 is fixedly connected to a fixing ear 402. A long plate 403 is fixedly connected to one side of each fixing ear 402. A limiting groove 404 is provided in the middle of the long plate 403. The outer wall of the limiting rod 305 is slidably connected in the limiting groove 404.

[0042] Specifically, when the pressing roller 306 moves down to contact the fabric surface, as the pressing roller 306 continues to move down, it forces the movable rod 311 to move down along the through hole of the base 1. The second spring 312 is compressed, and the placement plate 313 and the second electrode block 314 at the bottom move down synchronously. When the second electrode block 314 moves down to contact the first electrode block 315, the indicator light 317 is energized and illuminates, indicating that the appropriate pressing height has been reached. The placement plate 313 stops moving down. At this time, the moving block 301 continues to move down. Under the limiting constraint of the limiting slide groove 404, the two swing rods 303 drive the two limiting rods 305 to move away from each other, thereby driving the two pressing rollers 306 to expand outward to both sides synchronously, so as to flatten the fabric laterally and effectively eliminate fabric wrinkles.

[0043] Please see the appendix Figure 5 -Appendix Figure 10 The dust collection assembly includes a dust collection box 5, the top of which is fixedly connected to the bottom of the base 1. A dust collection hood 501 is fixedly connected to the bottom of the long plate 403. A dust collection hose 502 is fixedly connected between the dust collection hood 501 and the dust collection box 5. An outer sleeve 503 is fixedly connected to the middle of the dust collection hose 502. The bottom of the outer sleeve 503 is fixedly connected to the top of the base 1. A lifting column 504 is slidably connected inside the outer sleeve 503. A connecting hole 505 is opened inside the lifting column 504. The top of the lifting column 504 is fixedly connected to the bottom of the placement plate 313. A dust collection pump 509 is installed on one side of the dust collection box 5. An air suction pipe is fixedly connected to the input port of the dust collection pump 509. One end of the air suction pipe is fixedly connected to one side of the dust collection box 5. An air outlet pipe is fixedly connected to the output port of the dust collection pump 509.

[0044] Specifically, when the placement plate 313 moves down, the lifting column 504 at its bottom moves down synchronously along the inner wall of the outer sleeve 503. After the fabric is pressed, flattened and positioned, the lifting column 504 moves down the connecting hole 505 inside it to precisely connect with the dust suction hose 502. With the cooperation of the dust suction pump 509, the gas inside the dust collection box 5 is extracted through the suction pipe and discharged through the exhaust pipe, so that a negative pressure is formed inside the dust collection box 5. The lint and debris generated during the processing are efficiently sucked in by the dust suction hood 501 under the action of negative pressure and transported to the dust collection box 5 through the dust suction hose 502. This allows the lint and debris generated during the processing to be cleaned and collected, keeping the work surface clean and improving the processing environment and fabric quality.

[0045] After processing, the motor 308 reverses and drives the moving block 301 to move upward. The spring 304 pulls the swing arm 303 to reset, the two pressing rollers 306 move closer to each other, and at the same time the spring 312 rebounds, lifting the placement plate 313. The second electrode block 314 separates from the first electrode block 315, the indicator light 317 goes out, the lifting column 504 moves upward to make the connecting hole 505 and the dust suction hose 502 misaligned, the dust suction passage is automatically closed, and the device returns to its initial state, which is convenient for the next material positioning operation.

[0046] Please see the appendix Figure 10 The dust collection box 5 is equipped with an arc-shaped filter screen inside, which is arranged around the port of the exhaust pipe. The outer wall of the dust collection box 5 has a discharge port 506. The outer wall of the dust collection box 5 is symmetrically and fixedly connected with limit slide rails 507. The two limit slide rails 507 are located on both sides of the discharge port 506. The two limit slide rails 507 are slidably connected with sealing plates 508 inside.

[0047] Specifically, during normal vacuuming operations, the sealing plate 508 completely blocks the discharge port 506, keeping the inside of the dust collection box 5 in a good sealed state, ensuring that a stable negative pressure is quickly formed inside the dust collection box 5 when the vacuum pump 509 is working, thus ensuring the vacuuming effect.

[0048] When there are many impurities accumulated in the dust collection box 5 and they need to be cleaned and removed, slide the sealing plate 508 upward along the limit slide rail 507 to open the discharge port 506, and quickly remove the lint, debris and other impurities collected in the dust collection box 5 through the discharge port 506. After cleaning, push the sealing plate 508 downward to reseal the discharge port 506 and restore the sealed state for continued use.

[0049] By installing an arc-shaped filter screen inside the dust collection box 5, blockage of the air extraction pipe port can be avoided, ensuring smooth dust collection operations.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
