Description

Technical Field

[0001] The present application relates to the technical field of cloth production equipment, and in particular to a quality detection device for cloth. Background Art

[0002] Lace fabric usually refers to fabric with lace, also called lace fabric; because the fabric is light and transparent, it has an elegant and mysterious artistic effect. It covers almost the entire textile industry, and all textiles can be added with beautiful lace elements.

[0003] After production, lace fabrics are typically stored loosely in a rack. Before they can be sold, they must undergo quality inspection to detect any processing flaws. To facilitate sales, the inspected lace fabrics are rolled so they can be wound around a shaft for easy packaging and transportation.

[0004] In the prior art, most quality inspection devices for lace fabrics include an inspection table and a pair of pressing rollers. The inspection table is used for staff to inspect the lace fabric. The frame for storing the lace fabric is located on one side of the inspection table, and there is a distance between the frame and the inspection table. The two pressing rollers are both rotatably connected to the inspection table and are used to convey the lace fabric.

[0005] The lace fabric in the frame passes through the gap between the two pressing rollers. Under the action of friction, the two pressing rollers continuously transport the lace fabric to the table of the inspection table, and then the staff stands at the output position of the two pressing rollers to conduct inspection.

[0006] Regarding the aforementioned related technologies, during the inspection process, the lace fabric must first be stretched out to a certain length on the inspection table before being passed through two pressing rollers. Since the lace fabric must first be stretched out for a certain length on the inspection table, the overall length of the inspection table is relatively long, requiring a large amount of space, and thus needs to be improved. Summary of the Invention

[0007] In order to reduce the overall length of the inspection table when inspecting the quality of lace fabric, the present application provides a quality inspection device for fabric.

[0008] The present application provides a device for detecting the quality of fabrics using the following technical solutions:

[0009] A quality inspection device for fabrics, comprising an inspection table, a material feeding assembly, a lifting frame and a support member, wherein the lifting frame is arranged on the inspection table, the support member is arranged on the lifting frame and is located above the table top of the inspection table, and the support member is used to support lace fabric; the material feeding assembly is arranged on the inspection table and is located on the same side as the lifting frame, and the material feeding assembly is used to convey the lace fabric supported by the support member.

[0010] By adopting this technical solution, the frame for storing lace fabric is located on the side of the inspection table, near the elevated frame. During inspection, the lace fabric is pulled from the frame away from the ground onto the support member, which provides support for the lace fabric. The lace fabric on the support member is then pulled closer to the ground to the feed assembly, which exerts a tensile force on the lace fabric, allowing it to be continuously transported out of the frame. Finally, the staff inspects the lace fabric on the inspection table.

[0011] The lifting frame serves as a carrier for the installation of the support member, ensuring that the distance between the support member and the ground is greater than the distance between the inspection table and the ground. The support of the support member prevents the lace fabric from dripping onto the ground and coming into contact with it. By elevating the position of the lace fabric to be inspected, the lace fabric is always kept at a certain height from the ground. In other words, the lace fabric is spread out vertically, making full use of the vertical space and does not need to be spread horizontally on the inspection table. This reduces the overall length of the inspection table when inspecting the quality of the lace fabric, while also reducing the overall footprint of the inspection table.

[0012] Preferably, it also includes a first limiting rod, a second limiting rod and an adjusting member, the first limiting rod and the second limiting rod are both arranged on the lifting frame, and the adjusting member is simultaneously arranged on the first limiting rod and the second limiting rod, and a limiting groove is formed between the first limiting rod, the second limiting rod, the lifting frame and the adjusting member, and the limiting groove is located below the supporting member and is used for allowing lace fabric to pass through.

[0013] By adopting the above technical solution, the lace fabric in the frame can pass through the limiting groove and then pass through the support member. The limiting groove has a limiting effect on the lace fabric, preventing the lace fabric from shifting during the traction process.

[0014] In addition, the size of the limiting groove can be changed by changing the position of the adjusting member relative to the first limiting rod.

[0015] Preferably, an infrared sensor is further included, which is arranged on the lifting frame and close to the limiting groove, and the infrared sensor is used to detect whether there is lace fabric at the limiting groove.

[0016] By adopting the above technical solution, the infrared sensor uses infrared light for data processing. The infrared sensor is used to detect whether the lace fabric in the limit slot has been used up. When the sensor detects that no lace fabric has passed through the limit slot, an alarm signal is issued through a warning device, so that the staff at the inspection table can promptly know the status of the lace fabric in the frame. The warning device may include a warning light, a voice broadcast device, or an alarm.

[0017] Preferably, the lifting frame includes an upper frame and a lower frame, the lower frame is arranged on the inspection table, the upper frame is located above the lower frame and is rotatably connected to the lower frame, and the support member is arranged on the upper frame.

[0018] By adopting the above technical solution, the overall height of the lifting frame from the ground makes it difficult to pull the lace fabric onto the support. By configuring the lifting frame as an upper frame and a lower frame, the upper frame can be rotated from a vertical position to a nearly horizontal position before testing, allowing the lace fabric to be wound around the support. After winding is completed, the upper frame can be rotated back to a vertical position.

[0019] Preferably, it also includes a gas spring and a sliding assembly, the sliding assembly is slidably adjusted on the upper frame, the sliding assembly is arranged along the length direction of the upper frame, and the upper frame is provided with a sliding groove for the sliding assembly to slide; the gas spring is rotatably connected to the lower frame, and the piston rod of the gas spring is rotatably connected to the sliding assembly.

[0020] By adopting the above technical solution, the gas spring is used to control the rotation of the upper frame on the lower frame, while also supporting the upper frame to prevent the upper frame from spontaneously rotating under the action of gravity and posing a danger to personnel. A triangular structure is formed between the gas spring, the upper frame, and the lower frame. When the upper frame is in a vertical position, the gas spring's piston rod is supported on the end of the upper frame away from the lower frame. When the upper frame rotates, the gas spring's piston rod contracts (i.e., the length of the side of the gas spring shortens), causing the upper frame to begin to tilt. At this point, the sliding assembly slides within the slide groove in the direction closer to the lower frame to accommodate the changes in the gas spring's piston rod.

[0021] Preferably, the sliding assembly includes a ball bearing, a connecting block and a connecting plate, the ball bearing slides in the slide groove, and the outer ring is tangent to the slide groove, one end of the connecting block is connected to the inner ring of the ball bearing, and the other end passes through the slide groove and is connected to the connecting plate, and the piston rod of the gas spring is rotatably connected to the connecting block; a plurality of ridges are provided on the side of the connecting plate facing the upper frame, the length direction of the ridges is parallel to the sliding direction of the ball bearing, and the end face of the ridge in contact with the upper frame is arranged in an arc shape.

[0022] By adopting this technical solution, when the piston rod of the gas spring extends, the outer ring of the ball bearing slides within the chute, transforming sliding into rolling motion and reducing the friction of the ball bearing moving within the chute. Simultaneously, the connecting plate slides along with the ball bearing, and the ridges act to reduce friction between the connecting plate and the upper frame.

[0023] Preferably, it further includes a driving motor, the support member is rotatably connected to the lifting frame, and an anti-slip pad is provided on the surface of the support member; the driving motor is connected to the support member to control the rotation of the support member.

[0024] By adopting this technical solution, the surface roughness of the anti-slip mat is relatively high, ensuring friction between the lace fabric and the support when the lace fabric is placed on the support. The drive motor is used to control the rotation of the support on the lifting frame. Under the action of friction, the support actively pulls the lace fabric, allowing some lace fabric to drape between the support and the feed assembly. In other words, the conveyance of the lace fabric does not rely entirely on the traction of the feed assembly, preventing the lace fabric from being deformed by tension.

[0025] Preferably, the feeding assembly includes an active roller and a driven roller, and the active roller and the driven roller are both rotatably connected to the inspection table, and the rotation axes of the active roller and the driven roller are parallel to each other, and the lace fabric supported by the support member passes between the active roller and the driven roller.

[0026] By adopting the above technical solution, the lace fabric supported by the support member passes through the gap between the active roller and the driven roller. When the active roller rotates, under the action of pressure and friction, the driven roller rotates following the active roller, thereby achieving traction of the lace fabric.

[0027] Preferably, it also includes a rotating frame, a return spring and a sliding member, the rotating frame is rotatably connected to the inspection table, the rotation axis of the rotating frame is parallel to the rotation axis of the active roller, and the driven roller is rotatably connected to the rotating frame; the sliding member is slidably arranged on the inspection table, one end of the return spring is connected to the rotating frame, and the other end is connected to the sliding member, so that the driven roller is pressed on the active roller.

[0028] By adopting the above-mentioned technical solution, the rotating frame serves as a carrier for mounting the driven roller. The rotating frame is connected to the inspection table via a return spring. The return spring exerts a certain elastic force on the rotating frame, allowing the driven roller to press against the active roller. The pressing force between the driven roller and the active roller is related to the stretch of the return spring. When the sliding member is controlled to slide on the inspection table, the relative position of the sliding member and the rotating frame changes, and the length of the two ends of the return spring changes, thereby changing the stretch of the return spring. The elastic force of the return spring acting on the rotating frame also increases or decreases accordingly, thereby changing the pressing force between the active roller and the driven roller.

[0029] Preferably, it further includes a guide rod, which is arranged on the lifting frame. The lace fabric supported by the support member first passes through the guide rod and then enters the feeding assembly.

[0030] By adopting the above technical solution, the guide rod can play a guiding role so that the lace fabric can be better pulled from the support member to the feed assembly.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] (1) By setting up a lifting frame and a support, the lace fabric is pulled from the frame in a direction away from the ground to the support, and the support plays a supporting role for the lace fabric; then the lace fabric on the support is pulled in a direction close to the ground to the feeding assembly; the feeding assembly delivers the lace fabric to the surface of the inspection table, and finally the staff inspects the lace fabric on the inspection table. The lace fabric is spread out in a vertical direction, making full use of the vertical space, and does not need to be spread out horizontally on the inspection table, so that the overall length of the inspection table can be reduced when inspecting the quality of the lace fabric.

[0033] (2) By setting the lifting frame as an upper frame and a lower frame, the upper frame can be rotated from a vertical state to a nearly horizontal state before testing, so that the staff can wrap the lace fabric around the support; after the wrapping is completed, the upper frame can be rotated to a vertical state.

[0034] (3) By setting up a rotating frame, a sliding member, and a return spring, the rotating frame can press the driven roller against the active roller under the action of the return spring. When the sliding member is controlled to slide on the inspection table, the length of the two ends of the return spring changes, and the elastic force of the return spring acting on the rotating frame also changes accordingly, thereby changing the pressing force between the active roller and the driven roller.

[0045] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. Those skilled in the art can combine and combine the different embodiments or examples and the features of the different embodiments or examples indicated in the present application without conflict.

[0046] The embodiments of the present application disclose a quality detection device for cloth. Referring to Figure 1 , the quality detection device comprises an inspection table 1, a conveying assembly 2, a lifting frame 3 and a support 4. The inspection table 1 is installed on the ground, the table surface of the inspection table 1 is arranged in the horizontal direction, and the table surface is used for the quality inspection of the lace fabric by the worker. The lifting frame 3 is fixedly installed at one end of the inspection table 1, and the lifting frame 3 is arranged in the vertical direction; the support 4 is rod-shaped or tubular, and the support 4 is installed at the upper end of the lifting frame 3, so that the distance from the support 4 to the ground is much greater than the distance from the table surface of the inspection table 1 to the ground, and the support 4 is used to support the lace fabric. The conveying assembly 2 is installed at one end of the inspection table 1 and is located on the same side as the lifting frame 3, and the conveying assembly 2 is located above the table surface of the inspection table 1 and below the support 4, and the conveying assembly is used to convey the lace fabric supported by the support 4.

[0047] As shown, the frame body containing the lace fabric is located on the side of the inspection table 1 close to the lifting frame 3. During inspection, the lace fabric is pulled from the frame body in a direction away from the ground to the support 4, and the support 4 supports the lace fabric; then the lace fabric on the support 4 is pulled in a direction close to the ground to the conveying assembly 2, and the conveying assembly 2 has a pulling force on the lace fabric, so that the lace fabric can be continuously conveyed out of the frame body. Finally, the worker inspects the lace fabric on the inspection table 1.

[0048] By lifting the position of the lace fabric to be inspected, the lace fabric is always kept at a certain height from the ground. That is, the lace fabric is spread in the vertical direction, making full use of the vertical space, without spreading horizontally on the inspection table 1, so as to reduce the overall length of the inspection table 1 when inspecting the quality of the lace fabric, and also reduce the overall floor area of the inspection table 1.

[0049] According to some embodiments of the present application, optionally, please refer to Figure 2The lifting frame 3 includes an upper frame 31 and a lower frame 32. The lower frame 32 is fixedly mounted on the inspection table 1 in the vertical direction. The upper frame 31 is located above the lower frame 32 and is rotatably connected to the lower frame 32. The rotation axis of the upper frame 31 is parallel to the length direction of the support member 4. The upper frame 31 is also arranged in the vertical direction, and the support member 4 is installed at the end of the upper frame 31 away from the lower frame 32.

[0050] Because the lifting frame 3 is relatively high above the ground, it is difficult to pull the lace fabric onto the support 4. By configuring the lifting frame 3 with an upper frame 31 and a lower frame 32, the upper frame 31 can be rotated from a vertical position to a nearly horizontal position before testing to facilitate winding the lace fabric onto the support 4. After the lace fabric is wound, the upper frame 31 can be rotated back to a vertical position.

[0051] Specifically, a sliding assembly 5 is provided on the upper frame 31 for sliding movement, and the sliding assembly 5 slides along the length direction of the upper frame 31; a slide groove 6 for the sliding assembly 5 to slide is provided on the upper frame 31. A gas spring 7 is installed on the lower frame 32, and the gas spring 7 is rotatably connected to the lower frame 32, and the piston rod of the gas spring 7 is rotatably connected to the sliding assembly 5. In the prior art, the gas spring 7 is an industrial accessory that can perform functions such as support, buffering, braking, height adjustment and angle adjustment. In this embodiment, the gas spring 7 is used to support the upper frame 31 to prevent the upper frame 31 from spontaneously rotating under the action of gravity and causing danger to personnel. At the same time, the gas spring 7 can control the rotation of the upper frame 31 to achieve angle adjustment between the upper frame 31 and the lower frame 32.

[0052] The gas spring 7, upper frame 31, and lower frame 32 form a triangular structure. One side of the triangle is fixed, while the lengths of the other two sides and the sizes of the three internal angles vary during adjustment. When the upper frame 31 is in a vertical position, the piston rod of the gas spring 7 is supported on the end of the upper frame 31 away from the lower frame 32. When the upper frame 31 is in a vertical position, the piston rod of the gas spring 7 is supported on the end of the slide 6 away from the lower frame 32, and the sliding assembly 5 cannot move further within the slide 6.

[0053] When the upper frame 31 is rotated from vertical to horizontal, the piston rod of the gas spring 7 contracts (i.e., the length of the side of the gas spring 7 decreases), causing the upper frame 31 to begin to tilt. At this point, the sliding assembly 5 slides within the chute 6 toward the lower frame 32 to accommodate the movement of the piston rod of the gas spring 7.

[0054] Similarly, when the upper frame 31 rotates from horizontal to vertical, the piston rod of the gas spring 7 extends (i.e., the length of the side on which the gas spring 7 is located increases), causing the upper frame 31 to tilt. At this time, the sliding assembly 5 slides within the slide groove 6 in a direction away from the lower frame 32 to accommodate the movement of the piston rod of the gas spring 7.

[0055] Specific, combined Figure 3 The sliding assembly 5 includes a ball bearing 51, a connecting block 52, and a connecting plate 53. The sliding groove 6 is a T-shaped groove, with one end extending to the end of the upper frame 31 near the lower frame 32. A fixing sleeve 21 is mounted on the lower end of the upper frame 31 and secured to the upper frame 31 via fastening bolts or screws, making it removable. The ball bearing 51 slides within the sliding groove 6, with the outer ring of the ball bearing 51 tangential to the sliding groove 6. One end of the connecting block 52 is fixedly connected to the inner ring of the ball bearing 51, while the other end passes through the sliding groove 6 and connects to the connecting plate 53. The gas spring 7 is rotatably connected to the connecting block 52. The connecting plate 53 is rectangular in shape, with several ridges 22 integrally connected to the side of the connecting plate 53 facing the upper frame 31. The length of the ridges 22 is parallel to the sliding direction of the ball bearing 51, and the end faces of the ridges 22 that contact the upper frame 31 are arc-shaped.

[0056] When the piston rod of the gas spring 7 extends, the outer ring of the ball bearing 51 slides within the chute 6, transforming sliding into rolling, thereby reducing the friction of the ball bearing 51 moving within the chute 6. At the same time, the connecting plate 53 slides along with the ball bearing 51, and the ridges 22 act to reduce the friction between the connecting plate 53 and the upper frame 31.

[0057] According to some embodiments of the present application, optionally, please refer to Figure 2 . The first limiting rod 8, the second limiting rod 9 and the adjusting member 10 are respectively installed on the lower frame 32. The length of the first limiting rod 8 is parallel to the length direction of the support member 4, and one end of the first limiting rod 8 and one end of the second limiting rod 9 are both fixed on the lower frame 32; the first limiting rod 8 and the second limiting rod 9 are parallel to each other, and there is a distance between them, so that the first limiting rod 8 and the second limiting rod 9 are located on the same horizontal plane. The adjusting member 10 is also movably arranged on the first limiting rod 8 and the second limiting rod 9. The adjusting member 10 is block-shaped and is locked to the first limiting rod 8 and the second limiting rod 9 by bolts, so that the adjusting member 10 can move along the length direction of the first limiting rod 8 and be locked after movement.

[0058] The first limiting rod 8, the second limiting rod 9, the lower frame 32, and the adjusting member 10 enclose a limiting slot 11. This rectangular slot 11 is located below the support member 4 and is used to allow the lace fabric to pass through. Furthermore, when the adjusting member 10 is positioned relative to the first limiting rod 8, the size of the limiting slot 11 changes accordingly, allowing the space for the lace fabric to pass through the limiting slot 11 to be adjusted according to actual conditions. At this time, the force applied to the lace fabric as it passes through the limiting slot 11 also changes.

[0059] In addition, an infrared sensor 12 is mounted on the lower frame 32, and the infrared sensor 12 is located near the limit slot 11. In the prior art, an infrared sensor is a sensor that uses infrared light to process data. In this embodiment, the infrared sensor 12 is used to detect whether the lace fabric in the limit slot 11 has been used up. When the sensor detects that no lace fabric has passed through the limit slot 11, an alarm signal is issued through a warning device so that the staff on the inspection station 1 can promptly be informed of the condition of the lace fabric in the frame. The warning device may include a warning light, a voice broadcast device, or an alarm, so that the staff does not need to constantly pay attention to the lace fabric in the frame during the inspection process.

[0060] According to some embodiments of the present application, optionally, please refer to Figure 2 . A driving motor 13 is also installed on the upper frame 31, and the support member 4 is rotatably connected to the upper frame 31, and the support member 4 rotates with its own length direction as the axis of rotation. An anti-slip pad (not shown in the figure) is provided on the surface of the support member 4, and the anti-slip pad is made of polymer materials such as PVC soft glue, AB glue, rubber, PU, ​​and ordinary silicone. The polymer material has a strong adsorption capacity and a relatively rough surface, which increases the static friction coefficient of the contact between the lace fabric and the support member 4, thereby increasing the maximum static friction force between the lace fabric and the support member 4. The driving motor 13 and the support member 4 are connected by a belt drive, which is used to control the rotation of the support member 4. Of course, the driving motor 13 and the support member 4 can also be connected by a chain drive.

[0061] When the lace fabric is placed on the support member 4, friction between the lace fabric and the support member 4 is maintained. When the drive motor 13 controls the support member 4 to rotate, the friction force allows the support member 4 to actively pull the lace fabric, allowing some of the lace fabric to drape between the support member 4 and the feed assembly 2. In other words, the conveyance of the lace fabric does not rely entirely on the traction of the feed assembly 2, preventing the lace fabric from being deformed by tension.

[0062] According to some embodiments of the present application, optionally, please refer to Figure 2Several guide rods 14 are also mounted on the lifting frame 3. The length of the guide rods 14 is parallel to the length of the support member 4. As shown in the figure, there are two guide rods 14 on the lifting frame 3. One guide rod 14 is fixed to the upper frame 31 and is close to the support member 4. The other guide rod 14 is fixed to the lower frame 32 and is close to the feed assembly 2. The guide rods 14 serve as guides. The lace fabric supported by the support member 4 first passes through the two guide rods 14 in sequence before entering the feed assembly 2.

[0063] Two movable blocks 15 are mounted on the guide rod 14. These blocks 15 have a circular cross-section and move along the length of the guide rod 14. Both blocks 15 are bolted to the guide rod 14. As the lace fabric passes between the two blocks 15, they restrain the long sides of the fabric, thereby controlling its position on the guide rod 14.

[0064] Specifically, refer to Figure 4 The feed assembly 2 includes a driving roller 21 and a driven roller 22. A turret 16 is rotatably mounted on the inspection table 1. The driving roller 21 is rotatably connected to the inspection table 1, with its axis of rotation parallel to the length of the support member 4. The axis of rotation of the turret 16 is parallel to that of the driving roller 21. The driven roller 22 is rotatably connected to the turret 16, with its axis of rotation parallel to that of the driving roller 21. When the driving roller 21 rotates, the driven roller 22 rotates in tandem with the driving roller 21 under the action of pressure and friction, thereby pulling the lace fabric.

[0065] In addition, combined Figure 5 A return spring 17 and a sliding member 18 are also mounted on the inspection table 1. The sliding member 18 is slidably adjusted on the inspection table 1. One end of the return spring 17 is connected to the rotating frame 16, and the other end is connected to the sliding member 18. The return spring 17 is in a stretched state, allowing the driven roller 22 to press against the active roller 21.

[0066] The pressing force between the driven roller 22 and the driving roller 21 is related to the stretch of the return spring 17. When the control sliding member 18 slides on the inspection table 1, the relative position of the sliding member 18 and the rotating frame 16 changes, and the length of the two ends of the return spring 17 changes, which changes the stretch of the return spring 17. The elastic force of the return spring 17 acting on the rotating frame 16 also increases or decreases accordingly, thereby changing the pressing force between the driving roller 21 and the driven roller 22.

[0067] Specifically, a fixed block 19 is fixed to the inspection table 1. A strip-shaped hole 20 is formed in the fixed block 19 along the sliding direction of the slider 18. The slider 18 has an external thread on its outer surface. The slider 18 passes through the strip-shaped hole 20 and is screwed to a nut, which fixes the position of the slider 18 relative to the fixed block 19. When the slider 18 is locked to different positions on the fixed block 19, the tension of the return spring 17 can be changed.

[0068] The implementation principle of a quality inspection device for fabrics in an embodiment of the present application is as follows: during inspection, the lace fabric passes through the limiting groove 11 from the frame, and is then vertically pulled away from the ground to the support member 4, which supports the lace fabric.

[0069] The lace fabric, supported by the support member 4, passes around the guide rod 14 and then through the gap between the active roller 21 and the driven roller 22. As the active roller 21 rotates, the driven roller 22 rotates with it under the influence of pressure and friction, thereby pulling the lace fabric. Finally, the lace fabric is transported to the surface of the inspection table 1, where staff conduct quality inspections.

[0070] Lifting frame 3 serves as a carrier for mounting support member 4, ensuring that the distance between support member 4 and the ground is greater than the distance between the surface of test bench 1 and the ground. Supported by support member 4, lace fabric is prevented from dripping onto the ground and coming into contact with it. In other words, the lace fabric is spread vertically, fully utilizing the vertical space and eliminating the need for horizontal spreading on test bench 1. This reduces the overall length of test bench 1 and its overall footprint when inspecting lace fabric quality.

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
