Description

Technical Field

[0001] This utility model relates to the field of fabric testing, and in particular to a fabric testing table. Background Technology

[0002] In existing technologies, color difference detection of fabric rolls is required before they are cut into car seat cushions. Currently, most fabric color difference detection relies on manual visual observation, which is not precise enough. Small color differences are difficult to detect, resulting in low efficiency and compromised quality. Furthermore, existing detection methods often involve moving the fabric at a constant speed using two sets of rollers, detecting color differences during this process. However, the movement of the fabric makes it difficult for workers to accurately pinpoint the location of color differences, leading to inaccurate observation. Additionally, the cutting section needs to be marked and the fabric needs to be flattened during the fabric movement. Utility Model Content

[0003] This application provides a fabric inspection station, which solves the problem that in the prior art, the inspection is often carried out by moving the fabric at a constant speed with two sets of rollers. The color difference of the fabric is detected during the movement of the fabric. However, the movement of the fabric makes it difficult for the staff to accurately capture the position of the color difference, resulting in inaccurate observation. At the same time, the cutting part needs to be marked and the fabric needs to be flattened during the movement of the fabric.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0005] A fabric inspection table includes a support, a worktable mounted on the support, a light source for detecting fabric color, a first roller for keeping the fabric in constant contact with the worktable, a take-up roller, an unwinding roller, a leveling component for leveling the fabric on the worktable, and an intermittent device for intermittently moving the fabric; the intermittent device is mounted on the support and its actuating end is connected to the unwinding roller; the first roller is mounted on both sides of the worktable.

[0006] The first roller is tangent to the top surface of the worktable; the leveling component moves along the worktable; the light source of the lamp body faces the worktable; the take-up roller and the unwind roller are respectively disposed on both sides of the support.

[0007] As a further improvement to the above technical solution: the intermittent device includes a first block, a second block disposed on the first block, a driving member disposed on the support, and a third block that drives the first block to rotate; the third block has a sliding groove; first grooves are formed on both sides of the sliding groove; first baffles are provided at the diagonal positions on both sides of the first groove; the second block slides in the first groove; when the second block abuts against the first baffle, the second block currently located in the sliding groove moves out of the sliding groove and simultaneously drives the adjacent second block to move into the sliding groove, so that the first block moves intermittently; a plurality of second blocks are arranged in a circumferential array; the first block is connected to the unwinding roller and the first block drives the unwinding roller to rotate synchronously.

[0008] As a further improvement to the above technical solution: the leveling component includes a fourth piece, a connecting rod hinged to the fourth piece, a pressure roller for leveling the fabric, and a handle for lifting or lowering the pressure roller; a second groove is provided on the support; the fourth piece slides in the second groove; a guide rod is provided in the second groove; the guide rod passes through the fourth piece; the handle is provided on the end face of the connecting rod away from the fourth piece; the pressure roller rotates on the connecting rod; when the connecting rod is horizontal, the pressure roller contacts the top surface of the worktable.

[0009] As a further improvement to the above technical solution: a fifth block is provided on the handle; a third groove is provided on the support; the fifth block corresponds to the third groove; a second baffle is provided on the handle; a fourth groove is provided on the connecting rod; the second baffle slides within the fourth groove; an elastic element is sleeved on the handle; one end of the elastic element abuts against the second baffle, and the other end of the elastic element abuts against the side wall of the fourth groove; the elastic element drives the handle to move towards the connecting rod at all times.

[0010] As a further improvement to the above technical solution: rotate the connecting rod so that the pressure roller moves toward the worktable, then pull the handle outward until the fifth block extends beyond the outside of the worktable, so that the pressure roller contacts the top surface of the worktable, then release the handle and use the elastic element to insert the fifth block into the third groove, and move the handle to drive the pressure roller to move along the worktable.

[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0012] 1. Due to the intermittent device of the chute and the first baffle, the unwinding roller is periodically stopped, ensuring the fabric remains completely still under the illumination of the lamp, eliminating motion blur interference to the naked eye or optical sensors; the lamp covers the detection area of ​​the worktable at a vertical angle, forming a shadowless and uniform light field on the fabric surface after the pressure roller has leveled it, avoiding misjudgments caused by textures or wrinkles; the elastic element of the leveling component automatically engages the handle in the third groove, allowing for single-handed pressure to fix the pressure roller in contact with the fabric, while simultaneously moving the handle to slide the pressure roller along the worktable, completing leveling and pre-marking in sync, reducing manual step-by-step operations; the pressure roller uses a soft covering layer to avoid scratching high-gloss fabrics (such as automotive seat leather) during the leveling process. It is designed to meet the testing needs of various materials. The second block of the circumferential array achieves intermittent movement of the unwinding roller through a sliding groove, and the fabric movement-stationary rhythm is adjustable to adapt to the response time requirements of different testing equipment (such as manual visual inspection or machine vision). The first roller is designed to be tangent to the top surface of the worktable, which automatically counteracts the inertial relaxation of the fabric during intermittent pauses, maintains constant tension in the testing section, and avoids wrinkles from rebounding and affecting the testing results. The unwinding and take-up rollers are placed on both sides of the support, and with the mechanical transmission of the intermittent device, the fabric is automatically rewound after testing. A single person can complete the entire process of testing-marking-rewinding in one operation. The sliding limit of the second baffle and the fourth groove prevents the handle from accidentally coming off, ensures stable pressure of the pressure roller during the leveling process, and reduces the frequency of repetitive operations.

[0018] This application provides a fabric inspection station, which solves the problem that in the prior art, the inspection is often carried out by moving the fabric at a constant speed with two sets of rollers. The color difference of the fabric is detected during the movement of the fabric. However, the movement of the fabric makes it difficult for the staff to accurately capture the position of the color difference, resulting in inaccurate observation. At the same time, the cutting part needs to be marked and the fabric needs to be flattened during the movement of the fabric.

[0019] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] A fabric inspection table includes a support 1, a worktable 2 mounted on the support 1, a lamp body 3 for detecting fabric color, a first roller 4 for keeping the fabric in constant contact with the worktable 2, a take-up roller 5, an unwinding roller 6, a leveling component 7 for leveling the fabric on the worktable 2, and an intermittent device 8 for intermittently moving the fabric; the intermittent device 8 is mounted on the support 1 and its working end is connected to the unwinding roller 6; the first roller 4 is mounted on both sides of the worktable 2; the first roller 4 is tangent to the top surface of the worktable 2; the leveling component 7 moves along the worktable 2; the light source of the lamp body 3 faces the worktable 2; the take-up roller 5 and the unwinding roller 6 are respectively mounted on both sides of the support 1.

[0022] The intermittent device 8 includes a first block 81, a second block 82 disposed on the first block 81, a driving member 83 disposed on the support 1, and a third block 84 that drives the first block 81 to rotate; the third block 84 has a sliding groove 841; the sliding groove 841 has first grooves 842 on both sides; the first grooves 842 have first baffles 843 at opposite corners on both sides; the second block 82 slides in the first grooves 842; when the second block 82 abuts against the first baffles 843, the second block 82 currently located in the sliding groove 841 moves out of the sliding groove 841 and simultaneously drives the adjacent second block 82 to move into the sliding groove 841, so that the first block 81 moves intermittently; several second blocks 82 are arranged in a circumferential array; the first block 81 is connected to the unwinding roller 6 and the first block 81 drives the unwinding roller 6 to rotate synchronously.

[0023] The leveling component 7 includes a fourth block 71, a connecting rod 72 hinged to the fourth block 71, a pressure roller 73 for leveling the fabric, and a handle 74 for raising or lowering the pressure roller 73. A second groove 11 is provided on the support 1. The fourth block 71 slides in the second groove 11. A guide rod 12 is provided in the second groove 11. The guide rod 12 passes through the fourth block 71. The handle 74 is provided on the end face of the connecting rod 72 away from the fourth block 71. The pressure roller 73 rotates on the connecting rod 72. When the connecting rod 72 is horizontal, the pressure roller 73 contacts the top surface of the worktable 2.

[0024] A fifth piece 741 is provided on the handle 74; a third groove 21 is provided on the support 1; the fifth piece 741 corresponds to the third groove 21; a second baffle 742 is provided on the handle 74; a fourth groove 721 is provided on the connecting rod 72; the second baffle 742 slides within the fourth groove 721; an elastic element 743 is sleeved on the handle 74; one end of the elastic element 743 abuts against the second baffle 742, and the other end of the elastic element 743 abuts against the side wall of the fourth groove 721; the elastic element 743 drives the handle 74 to move towards the connecting rod 72 at all times.

[0025] Rotate the connecting rod 72 until the pressure roller 73 moves toward the worktable 2. Then pull the handle 74 outward until the fifth block 741 extends beyond the outside of the worktable 2, so that the pressure roller 73 contacts the top surface of the worktable 2. Then release the handle and use the elastic element 743 to insert the fifth block 741 into the third groove 21. Move the handle 74 to drive the pressure roller 73 to move along the worktable 2.

[0026] Because the intermittent device 8 uses a chute 841 that works in conjunction with the first baffle 843 to periodically stop the unwinding roller 6, the fabric remains completely still under the illumination of the lamp body 3, eliminating motion blur interference to the naked eye or optical sensors. The lamp body 3 covers the detection area of ​​the workbench 2 at a vertical angle, and combined with the fabric surface after being leveled by the pressure roller 73, it forms a shadow-free and uniform light field, avoiding misjudgments caused by textures or wrinkles. The elastic element 743 of the leveling component 7 drives the handle 74 to automatically engage with the third groove 21. Pressing down with one hand can fix the pressure roller 73 in contact with the fabric. At the same time, moving the handle 74 moves the pressure roller 73 along the workbench 2, completing leveling and pre-marking simultaneously, reducing manual step-by-step operations. The pressure roller 73 uses a soft covering layer to avoid scratching high-gloss fabrics (such as car seat leather) during the leveling process. The fabric is designed to be compatible with various materials for testing. The second block 82 of the circumferential array switches through the slide groove 841 to achieve intermittent movement of the unwinding roller 6. The fabric movement-stationary rhythm is adjustable to meet the response time requirements of different testing equipment (such as manual visual inspection or machine vision). The first roller 4 is designed to be tangent to the top surface of the worktable 2. During intermittent pauses, it automatically offsets the inertial relaxation of the fabric, maintains constant tension in the testing section, and avoids wrinkles from rebounding and affecting the testing results. The unwinding and winding rollers 6 are placed on both sides of the support 1. With the mechanical transmission of the intermittent device 8, the fabric is automatically wound up after testing. A single person can complete the entire process of testing-marking-winding in one go. The sliding limit of the second baffle 742 and the fourth groove 721 prevents the handle 74 from accidentally coming off, ensures stable pressure of the pressure roller 73 during the leveling process, and reduces the frequency of repeated operations.
