Technical Field

[0001] The present invention relates to the technical field of garment fabric production and processing, and in particular to a garment fabric production and processing defect detection device and a use method thereof. Background Art

[0002] During the production and processing of clothing fabrics, due to the instability of weaving, dyeing, printing and other links, the fabrics may have defects such as broken yarn and holes. Therefore, a defect detection device is needed to detect the clothing fabrics to ensure the production quality of the product.

[0003] Currently, when detecting defects such as holes and broken yarns on clothing fabrics, it is usually necessary to place the clothing fabrics on a light board and then inspect them through manual visual inspection or industrial camera photography. The former is inefficient and easily affected by subjective factors, and the detection accuracy is relatively general.

[0009] Furthermore, the lifting plate is fixedly connected to the support plate, and the lifting plate is slidably connected to the support plate and the guide rod respectively.

[0010] Furthermore, a width adjustment component is provided on the upper part of the workbench, and the width adjustment component includes a limit frame, positive and negative threaded screws, a drive plate, a sealing plate and a guide groove.

[0011] Furthermore, a pressure regulating assembly is connected to the top of the driving rod, and the pressure regulating assembly includes a side plate, a worm, a worm wheel and a stud.

[0012] Furthermore, the voltage regulating assembly also includes a top plate, a limit rod and a return spring. The outer side of the lower end of the stud is threadedly connected to the top plate, and the inner side of the top plate is slidably connected to the limit rod. The limit rod is fixedly connected to the driving rod, and the outer side of the driving rod is sleeved with a return spring.

[0015] Furthermore, the method for using the clothing fabric production and processing defect detection device is applied to the clothing fabric production and processing defect detection device, and comprises the following steps: Step 1: Lift the lifting plate and spread the clothing fabric all over the top of the workbench, then let go. The lifting plate will move downward under the push of the compression spring, so that the pressing roller presses the fabric tightly, and then rotate the positive and negative thread screws inside the limit frame, so that the driving plates at both ends drive the sealing plates to slide, so that the opening width of the booster chamber can be adjusted according to the width of the clothing fabric; Step 2: Turn the worm, the worm wheel will drive the stud to rotate, so that the height of the top plate changes. At this time, the length of the return spring will also change, so as to adjust the default pressure on the drive rod according to the air permeability of the fabric; Step 3: Start the fan to deliver the air filtered by the filter to the boost chamber. At this time, since the clothing fabric covers the top of the workbench, the top of the boost chamber will be blocked, so that the airflow can only pass through the small gap inside the clothing fabric, dispersing the pressure of the airflow; Step 4: During the movement of the fabric, when the surface yarn or hole of the fabric passes through the top of the boost chamber, due to the large gap there, more airflow will be concentrated to pass through, so that the airflow thrust can be used to push the detection cover, so that the driving rod moves up, the rotating plate will rotate with the center of the support plate, and the guide rod will drive the pressing block to move down. At the same time, the sponge is stained with a water-soluble marking liquid of a wake-up color, so when the sponge contacts the fabric, the defects on the fabric can be automatically marked. At the same time, the space between the buffer box and the lifting plate will become larger, so that the airbag has a larger deformation recovery space, so that negative pressure can be formed inside the buffer box. At this time, the marking liquid inside the liquid storage tank will flow into the buffer box through the pressure valve and the first one-way valve; Step 5: When the defective part of the fabric is moved away from the bottom of the detection cover, the reset spring will push the driving rod to move down and reset under the limit of the top plate and the limit rod, so that the guide rod will move up and reset. At this time, the buffer box can be driven to squeeze the airbag, thereby increasing the pressure inside the second one-way valve, and the internal marking liquid will flow into the diversion hole through the hose, and flow out from the evenly distributed bottom holes to replenish the marking liquid stored in the sponge.

[0016] The present invention provides a clothing fabric production and processing defect detection device and a use method thereof, which have the following beneficial effects: 1. The fan of the present invention delivers the air filtered by the filter to the boost chamber. At this time, since the clothing fabric covers the top of the workbench, the top of the boost chamber is blocked, so that the airflow can only pass through the tiny gap inside the clothing fabric. When there are no broken yarns and holes on the surface of the fabric, the airflow passing through various parts of the fabric will be evenly distributed to disperse the pressure of the airflow. Since the pressure on the detection cover is small, it will not move. In the process of fabric movement, when the surface of the fabric has broken yarns or holes that pass through the top of the boost chamber, the fabric blocking force becomes smaller due to the larger gap there, and the detection cover will not move. Most of the airflow will be concentrated through it, so that the airflow thrust can be used to push the detection cover, so that the driving rod moves up, the rotating plate will rotate about the center of the support plate, and the guide rod will drive the pressure block to move down. At the same time, the sponge is stained with a water-soluble marking liquid of a bright color. Therefore, when the sponge comes into contact with the fabric, the defects on the fabric can be automatically marked, and subsequent personnel can observe the defects. Compared with the existing detection equipment, which requires manual and careful observation of the entire position of the fabric or the use of machine vision for shooting and identification, this application will not use too much cost while improving the detection efficiency, which is beneficial to improving the production efficiency of the enterprise.

[0017] 2. Before detecting clothing fabrics, the present invention first lifts the lifting plate and spreads the clothing fabrics on the top of the workbench and then lets go. The lifting plate will move downward under the push of the compression spring, so that the pressure roller presses the fabric, thereby limiting the bottom height of the detection component, so that clothing fabrics of different thicknesses can be detected. Subsequently, the positive and negative threaded screws inside the limit frame can be rotated so that the driving plates at both ends are centered or moved in the opposite direction at the same time, so that the sealing plate can slide along the guide groove, so that the opening width of the boost chamber can be adjusted according to the width of the clothing fabric, further improving the adaptation range of the equipment, and when detecting some clothing fabrics with good air permeability, by rotating the worm, the worm wheel drives the stud to rotate, so that the height of the top plate is reduced. At this time, the reset spring will provide a larger elastic force due to compression, avoiding pushing the detection cover due to more airflow. Therefore, the present application uses a multiple adjustment structure to enable the detection structure to adapt to various types of clothing fabrics, which is conducive to meeting the use requirements in different scenarios and is worthy of promotion.

[0018] 3. Since the present invention utilizes the airflow discharged by the fan for detection, the exhaust pipe can be connected to the front dust suction mechanism of the clothing fabric according to needs during use, providing a negative pressure environment for the dust suction mechanism, thereby making full use of energy and saving use costs. In the subsequent marking process, when the guide rod moves down, the space between the buffer box and the lifting plate will become larger, so that the airbag has a larger deformation recovery space, so that a negative pressure can be formed inside the buffer box. At this time, the pressure valve will be subjected to a large pressure and be in an open state, and the marking liquid inside the liquid storage tank will flow into the buffer box through the first one-way valve. After that, after the sponge contacts the clothing fabric and marks it, the guide rod will move up and reset, and at this time, the buffer box can be driven to squeeze the airbag, thereby increasing the pressure inside the second one-way valve, and the internal marking liquid will flow into the diversion hole through the hose, and flow out from the evenly distributed bottom holes to replenish the marking liquid stored in the sponge. Therefore, the equipment can be kept in operation for a long time during use, avoiding the impact of frequent shutdowns for maintenance on the product detection efficiency.

[0022] See also Figures 1 to 5The pressure supply component 2 includes a fan 201, a filter 202, an exhaust pipe 203, a pressurization chamber 204 and a perforated plate 205. The fan 201 is connected to one side of the workbench 1, and the filter 202 is arranged at one end of the fan 201, and the exhaust pipe 203 is arranged on one side of the filter 202. The pressurization chamber 204 is opened inside the workbench 1, and the pressurization chamber 204 is connected to the inside of the fan 201, and the perforated plate 205 is fixed inside the pressurization chamber 204. The four ends of the top of the workbench 1 are fixed with vertical rods 301, and the outer side of the upper end of the vertical rod 301 is sleeved with a compression spring 302, and the bottom of the compression spring 302 is connected to a lifting plate 303, and the lifting plate 303 is slidably connected to the vertical rod 301, and both sides of the lifting plate 303 are provided with A pressure roller 304 is arranged, the lifting plate 303 is fixedly connected with the support plate 401, and the lifting plate 303 is slidably connected with the support plate 401 and the guide rod 405 respectively, and a width adjustment component 5 is arranged on the upper part of the workbench 1, and the width adjustment component 5 comprises a limit frame 501, a positive and negative threaded screw 502, a driving plate 503, a sealing plate 504 and a guide groove 505, and the limit frames 501 are symmetrically arranged on both sides of the workbench 1, and the positive and negative threaded screw 502 is rotatably connected inside the limit frame 501, and the outer sides of the two ends of the positive and negative threaded screw 502 are threadedly connected with the driving plate 503, and the upper end of the driving plate 503 is fixed with a sealing plate 504, and a guide groove 505 is opened at the upper end of the middle part of the workbench 1, and the sealing plate 504 is slidably connected with the workbench 1 through the guide groove 505; The specific operation is as follows: lift the lifting plate 303 and spread the clothing fabric all over the top of the workbench 1, then let go, and the lifting plate 303 will move downward under the push of the compression spring 302, so that the pressing roller 304 presses the fabric, thereby limiting the bottom height of the detection component 4, so as to detect clothing fabrics of different thicknesses, and a hydrophobic layer is arranged on the outer side of the pressing roller 304, which will not adhere to the marking liquid, and the table top of the workbench 1 is made of smooth ceramic material, and the friction resistance between the workbench 1 and the clothing fabric is extremely small, which will not affect the subsequent normal movement of the clothing fabric. Subsequently, the forward and reverse threaded screws 502 inside the limit frame 501 can be rotated to make the driving plates 503 at both ends move in the middle or in the opposite direction at the same time, so that the sealing plate 504 can slide along the guide groove 505, so that the opening width of the boost chamber 204 can be adjusted according to the width of the clothing fabric, further improving the adaptation range of the device, and then the fan 201 is started to transport the air filtered by the filter 202 outside to the boost chamber 204. At this time, since the clothing fabric covers the top of the workbench 1, the top of the boost chamber 204 will be compressed. The airflow can only pass through the tiny gaps inside the clothing fabric, and when there are no broken yarns or holes on the surface of the fabric, the airflow passing through various parts of the fabric will be evenly distributed, dispersing the pressure of the airflow. Since the pressure on the detection cover 404 is small, it will not move. At the same time, the orifice plate 205 will guide the airflow that initially enters the pressurization chamber 204 to make it evenly distributed. Later, during the movement of the fabric, when the broken yarn or holes on the surface of the fabric pass through the top of the pressurization chamber 204, the gap there is larger, the blocking force of the fabric becomes smaller, and more air The airflow will be concentrated and pass through from here, so that the thrust of the airflow can be used to push the detection cover 404, so that the driving rod 403 moves up, the rotating plate 402 will rotate with the center of the support plate 401, and the guide rod 405 will drive the pressing block 406 to move down.

[0023] See also Figure 6 to Figure 7, a pressure regulating assembly 6 is connected to the top of the driving rod 403, and the pressure regulating assembly 6 includes a side plate 601, a worm 602, a worm wheel 603 and a stud 604. A side plate 601 is arranged at one end of the top of the lifting plate 303, and the upper end of the side plate 601 is rotatably connected to the worm 602, a worm wheel 603 is meshed on one side of the worm 602, and a stud 604 is fixed inside the worm wheel 603, and the stud 604 is rotatably connected to the side plate 601. The pressure regulating assembly 6 also includes a top plate 605, a limit rod 606 and a return spring 607. The outer side of the lower end of the stud 604 is threadedly connected to the top plate 605, and the inner side of the top plate 605 is slidably connected to the limit rod 606. The limit rod 606 is fixedly connected to the driving rod 403, and the outer side of the driving rod 403 is sleeved with a return spring 607. A liquid replenishing assembly 7 is arranged at the other end of the top of the lifting plate 303. The liquid replenishing assembly 7 includes a liquid storage tank 701, a pressure valve 702, a first one-way valve 703, and a buffer box 704. The other end of the top of the lifting plate 303 is provided with a liquid storage tank 701, and a pressure valve 702 is connected to one side of the liquid storage tank 701. The pressure valve 702 is connected to the first one-way valve 703 through a hose, and a buffer box 704 is provided on one side of the first one-way valve 703, and the buffer box 704 is fixedly connected to the guide rod 405. The liquid replenishing component 7 also includes an air bag 705, a second one-way valve 706 and a diverter hole 707. The top of the buffer box 704 is connected with the air bag 705, and the interior of the air bag 705 is connected to the interior of the buffer box 704, and a second one-way valve 706 is provided on one side of the buffer box 704. The interior of the pressing block 406 is provided with a diverter hole 707, and the second one-way valve 706 is connected to the interior of the diverter hole 707 through a hose; The specific operation is as follows. When testing some clothing fabrics with good air permeability, the worm 602 is rotated to make the worm wheel 603 drive the stud 604 to rotate, so that the height of the top plate 605 is reduced. At this time, the return spring 607 will provide a larger elastic force due to compression to avoid pushing the detection cover 404 due to the large amount of airflow passing through. Therefore, the present application uses a multiple adjustment structure to make the detection structure adaptable to various types of clothing fabrics, which is conducive to meeting the use requirements in different scenarios. In the subsequent process of marking the fabric, the space between the buffer box 704 and the lifting plate 303 will become larger, so that the airbag 705 has a larger deformation recovery space, so that a negative pressure can be formed inside the buffer box 704. At this time, the pressure valve 70 2 will be subjected to greater pressure and open, and the marking liquid inside the liquid storage tank 701 will flow into the buffer tank 704 through the first one-way valve 703. When the defective part of the fabric moves away from the bottom of the detection cover 404, the reset spring 607 will push the driving rod 403 to move down and reset under the limit of the top plate 605 and the limit rod 606, so that the guide rod 405 moves up and resets. At this time, the buffer tank 704 can be driven to squeeze the airbag 705, so that the pressure inside the second one-way valve 706 increases, and the internal marking liquid will flow into the diversion hole 707 through the hose, and flow out from the evenly distributed bottom holes to replenish the marking liquid stored in the sponge 407, so that the device can be kept in operation for a long time during use.

[0024] In summary, the device for detecting defects in the production and processing of clothing fabrics and the method for using the same, when in use, first lift the lifting plate 303 and spread the clothing fabrics all over the top of the workbench 1 and then release the lifting plate 303, the lifting plate 303 will move downward under the push of the compression spring 302, so that the pressing roller 304 presses the fabric, so as to detect clothing fabrics of different thicknesses, and then rotate the positive and negative threaded screws 502 inside the limit frame 501, so that the driving plates 503 at both ends are centered or moved in the opposite direction at the same time, so that the sealing plate 504 can slide along the guide groove 505, so that the opening width of the boost chamber 204 can be adjusted according to the width of the clothing fabric, and secondly, when detecting some clothing fabrics with good air permeability, by rotating the worm 602, the worm wheel 60 3 drives the stud 604 to rotate, so that the height of the top plate 605 is reduced. At this time, the return spring 607 will provide a larger elastic force due to compression to prevent the detection cover 404 from being pushed due to the large amount of airflow passing through. Then, the fan 201 is started to transport the air filtered by the filter 202 outside to the boost chamber 204. At the same time, the orifice plate 205 will guide the airflow entering the boost chamber 204 to make it evenly distributed. At this time, since the clothing fabric covers the top of the workbench 1, the top of the boost chamber 204 will be blocked, so that the airflow can only pass through the small gap inside the clothing fabric. When there is no broken yarn or hole on the surface of the fabric, the airflow passing through various parts of the fabric will be evenly distributed to disperse the pressure of the airflow. Then, when the fabric moves, During the movement, when the surface yarn of the fabric is broken or the hole passes through the top of the boost chamber 204, due to the larger gap there, the fabric blocking force becomes smaller, and more airflow will be concentrated to pass through it, so that the airflow thrust can be used to push the detection cover 404, so that the driving rod 403 moves up, the rotating plate 402 will rotate around the center of the support plate 401, and the guide rod 405 will drive the pressing block 406 to move down. At the same time, the sponge 407 is stained with a water-soluble marking liquid of a wake-up color. Therefore, when the sponge 407 contacts the fabric, the defects on the fabric can be automatically marked. In this process, the space between the buffer box 704 and the lifting plate 303 will become larger, so that the airbag 705 has a larger deformation recovery space, so that the internal shape of the buffer box 704 can be When the pressure valve 702 is under a relatively high pressure, it will open, and the marking liquid in the liquid storage tank 701 will flow into the buffer tank 704 through the first one-way valve 703. Finally, when the defective part of the fabric is removed from the bottom of the detection cover 404, the reset spring 607 will push the driving rod 403 to move down and reset under the limit of the top plate 605 and the limit rod 606, so that the guide rod 405 will move up and reset. At this time, the buffer tank 704 can be driven to squeeze the airbag 705, thereby increasing the pressure inside the second one-way valve 706, and the internal marking liquid will flow into the diversion hole 707 through the hose, and flow out from the evenly distributed bottom holes to replenish the marking liquid stored in the sponge 407, which is beneficial to maintain the continuous operation of the equipment.

10. A method for using a device for detecting defects in the production and processing of clothing fabrics, characterized in that: The garment fabric production and processing defect detection device as claimed in claim 9 comprises the following steps: Step 1: lift the lifting plate (303) and spread the clothing fabric all over the top of the workbench (1), then release the lifting plate (303), which will move downward under the push of the compression spring (302), so that the pressing roller (304) presses the fabric tightly, and then rotate the positive and negative threaded screws (502) inside the limit frame (501), so that the driving plates (503) at both ends drive the sealing plates (504) to slide, thereby adjusting the opening width of the boosting chamber (204) according to the width of the clothing fabric; Step 2: Rotate the worm (602), the worm wheel (603) drives the stud (604) to rotate, so that the height of the top plate (605) changes, and the length of the return spring (607) also changes, so as to adjust the default pressure of the driving rod (403) according to the air permeability of the fabric; Step 3: Start the fan (201) to deliver the air filtered by the filter (202) to the pressurizing chamber (204). At this time, since the clothing fabric covers the top of the workbench (1), the top of the pressurizing chamber (204) is blocked, so that the airflow can only pass through the small gaps inside the clothing fabric, thereby dispersing the pressure of the airflow; Step 4: During the movement of the fabric, when the surface yarn or hole of the fabric passes through the top of the boost chamber (204), due to the larger gap there, more airflow will be concentrated and pass through it, so that the thrust of the airflow can be used to push the detection cover (404), so that the driving rod (403) moves up, the rotating plate (402) will rotate around the center of the support plate (401), and the guide rod (405) will drive the pressing block (406) to move down. At the same time, the sponge (407) is stained with water of the color of the face. Soluble marking liquid, when the sponge (407) contacts the fabric, the defect on the fabric can be automatically marked, and at the same time, the space between the buffer box (704) and the lifting plate (303) will be enlarged, so that the airbag (705) has a larger deformation recovery space, so that negative pressure can be formed inside the buffer box (704), and the marking liquid inside the liquid storage tank (701) will flow into the buffer box (704) through the pressure valve (702) and the first one-way valve (703); Step 5: When the defective part of the fabric is moved away from the bottom of the detection cover (404), the reset spring (607) will push the driving rod (403) to move down and reset under the limit of the top plate (605) and the limit rod (606), thereby causing the guide rod (405) to move up and reset. At this time, the buffer box (704) can be driven to squeeze the airbag (705), thereby increasing the pressure inside the second one-way valve (706), and the marking liquid inside will flow into the diversion hole (707) through the hose, and flow out from the evenly distributed bottom holes to replenish the marking liquid stored in the sponge (407).
