Description

Technical Field

[0001] This utility model belongs to the field of tension adjustment technology for fabric inspection machines, specifically a tension adjustment device for fabric inspection machines. Background Technology

[0002] The tension adjustment device of the fabric inspection machine is a key component of the machine. It is mainly used to regulate the tension of the fabric during the inspection process to ensure that the fabric is always in a flat and stable state, thereby ensuring the accuracy and effectiveness of the inspection and facilitating the detection of fabric defects, color differences and other problems.

[0003] For example, the utility model with publication number CN223225456U relates to the field of fabric inspection machines, specifically disclosing a tension adjustment device for a fabric inspection machine used in garment processing. The device includes a worktable, an inspection table, a feeding roller, a receiving roller, and a tension adjustment roller. The inspection table is fixed on the worktable, and the feeding roller and receiving roller are fixed at the front and rear ends of the worktable, respectively. A groove and a cavity are provided in the middle of the inspection table, with the cavity located below the groove. A through hole is provided at the bottom of the groove, communicating with the cavity. A cylinder is installed inside the cavity. An adjustment roller base is provided at the bottom of the groove. The tension adjustment roller is rotatably connected to the adjustment roller base. By setting up the tension adjustment roller and installing it on the inspection table, and by providing a cylinder at the bottom of the tension adjustment roller, the height of the tension adjustment roller can be adjusted via the cylinder. This causes the fabric to be arched by the tension adjustment roller, increasing the tension of the fabric on the inspection table and making the fabric easier to observe. The above-mentioned device adjusts the tension of the fabric by using a cylinder and a tension adjusting roller. However, the above adjustment method has obvious defects. The cylinder adjustment is a rigid drive, so it is difficult to make accurate and timely adaptive adjustments according to the real-time state of the fabric (such as fabric thickness, material changes, running speed fluctuations, etc.). This results in insufficient tension control accuracy and the fabric is prone to being too loose or too tight, which affects the quality of fabric inspection. Therefore, a tension adjusting device for a fabric inspection machine is proposed to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a tension adjustment device for a fabric inspection machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension adjustment device for a fabric inspection machine, including a support base, a storage rack fixedly connected to one end of the top of the support base, a fabric roll placed on the top of the storage rack, friction arc plates bolted to the inner walls on both sides of the support base, and an adjustment component movably connected inside the support base; The adjustment assembly includes a first adjustment roller and a second adjustment roller. Two limiting blocks are symmetrically arranged on both sides of the inner wall of the support base. A connecting rod is movably sleeved on one end of each limiting block. Friction plates are fixedly connected to both ends of the second adjustment roller. A slider is fixedly connected to both ends of the first adjustment roller. A limiting rod is fixedly connected to the bottom of the slider. Two springs are movably sleeved on the surface of the limiting rod.

[0006] Preferably, the two ends of the connecting rod are hinged to the bottom ends of the two connecting rods respectively, and the two ends of the second adjusting roller are hinged to the top ends of the connecting rod respectively.

[0007] Preferably, the connecting rod has a straight groove in the middle that cooperates with the limiting block, and the connecting rod rotates about one end of the first adjusting roller as the axis.

[0008] Preferably, the raised surface of the friction arc plate is made of rubber material, and the adjusting component abuts against the raised surface of the friction arc plate.

[0009] Preferably, the bottom end of the limiting rod is slidably connected inside the support base, and the two ends of the spring are fixedly connected to the slider and the support base, respectively.

[0010] Preferably, the bottom of the first adjusting roller contacts the top of the fabric on the roll, and the top of the second adjusting roller contacts the bottom of the fabric.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves adaptive adjustment of fabric tension through the cooperation between the friction arc plate and the adjustment component. When the fabric tension is too high, the first adjustment roller is pulled upward and moves downward through the connecting rod, thereby shortening the fabric path length and reducing the tension. When the tension is too low, the spring pulls the first adjustment roller downward and moves the second adjustment roller upward in conjunction, thereby increasing the path length and increasing the tension until the tension and the spring force reach a balance. Thus, through the linkage of the first adjustment roller, the second adjustment roller, the connecting rod and the spring, adaptive adjustment of fabric tension is achieved without frequent manual intervention.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 4 As shown, this utility model provides a tension adjustment device for a fabric inspection machine, including a support base 1, a storage rack 2 fixedly connected to one end of the top of the support base 1, a fabric roll 3 placed on the top of the storage rack 2, friction arc plates 4 bolted to the inner walls on both sides of the support base 1, and an adjustment component 5 movably connected inside the support base 1. The adjusting component 5 includes a first adjusting roller 53 and a second adjusting roller 54. Two limiting blocks 51 are symmetrically arranged on both sides of the inner wall of the support base 1. A connecting rod 52 is movably sleeved at one end of the limiting block 51. Friction plates 55 are fixedly connected to both ends of the second adjusting roller 54. A slider 56 is fixedly connected to both ends of the first adjusting roller 53. A limiting rod 57 is fixedly connected to the bottom of the slider 56. Two springs 58 are movably sleeved on the surface of the limiting rod 57.

[0016] like Figure 3 and Figure 4 As shown, the two ends of the connecting rod 52 are respectively hinged to the bottom ends of the two connecting rods 52, the two ends of the second adjusting roller 54 are respectively hinged to the top ends of the connecting rod 52, and the middle part of the connecting rod 52 is provided with a straight groove that cooperates with the limiting block 51. The connecting rod 52 rotates about one end of the first adjusting roller 53 as the axis.

[0017] The above solution involves a straight slot in the middle of the connecting rod 52. The function of this slot is to allow the limiting block 51 to be movably engaged inside the straight slot of the connecting rod 52, thereby providing a fulcrum for the rotation of the connecting rod 52. This ensures that the connecting rod 52 can rotate stably around the limiting block 51 when under force. At the same time, the straight slot can compensate for the length difference of the connecting rod 52 during rotation, making the movement of the connecting rod 52 smoother, avoiding structural jamming, and ensuring the stability of tension adjustment.

[0018] like Figures 1 to 3As shown, the raised surface of the friction arc plate 4 is made of rubber material. The adjusting component 5 abuts against the raised surface of the friction arc plate 4. The bottom end of the limiting rod 57 is slidably connected inside the support base 1. The two ends of the spring 58 are fixedly connected to the slider 56 and the support base 1 respectively. The bottom of the first adjusting roller 53 contacts the top of the fabric on the fabric roll 3, and the top of the second adjusting roller 54 contacts the bottom of the fabric.

[0019] The above scheme involves the friction plate 55 abutting against the raised surface of the friction arc plate 4. Since the raised surface of the friction arc plate 4 is made of rubber, frictional resistance is generated when the friction plate 55 abuts against the raised surface. When the connecting rod 52 rotates due to changes in fabric tension, attempting to drive the second adjusting roller 54 directly downwards, the frictional resistance between the friction plate 55 and the raised surface of the friction arc plate 4 dampens the movement of the second adjusting roller 54. Therefore, the second adjusting roller 54 will only move the friction plate 55 when the force generated by the change in fabric tension is sufficient to overcome the frictional resistance of the rubber. This achieves precise and gradual tension adjustment, preventing drastic fluctuations in fabric tension due to excessive adjustment, thus ensuring the flatness and accuracy of the fabric during inspection and preventing uncontrolled rapid movement.

[0020] The working principle and usage process of this utility model are as follows: First, the operator inserts both ends of the fabric roll 3 into the storage rack 2 and pulls the fabric out of the fabric roll 3. Then, following the device path, the fabric passes through the bottom of the first adjusting roller 53 and the top of the second adjusting roller 54 in sequence, and then enters the inspection area of ​​the fabric inspection machine. Subsequently, the fabric defects, color differences, etc. are detected through the inspection area. After inspection, the other end of the fabric is wrapped around the take-up roller of the fabric inspection machine. The take-up roller provides traction force to drive the fabric to be continuously conveyed, so as to realize the continuous operation of the fabric inspection process. During the fabric conveying process, when the fabric tension is too high, the tension of the fabric will act on the first adjusting roller 53. The excessive tension will cause the first adjusting roller 53 to move upward against its own weight and the elastic force of the spring 58. As the first adjusting roller 53 moves upward, it will drive the connecting rod 52 to rotate around one end of the first adjusting roller 53 as the axis. Then, the connecting rod 52 will drive the second adjusting roller 54 to move downward. Thus, by moving the first adjusting roller 53 and the second adjusting roller 54, the wrapping angle of the fabric between the two rollers is changed, the path length is shortened, and the adaptive adjustment of the fabric tension is achieved, so that the fabric tension is restored to a suitable range, thereby avoiding the stretching and deformation of the fabric due to excessive tension. When the fabric has low tension, the tension of the fabric on the first adjusting roller 53 is insufficient, which cannot counteract the elastic tension of the spring 58 on the limiting rod 57. As a result, the spring 58 pulls the limiting rods 57 at both ends of the first adjusting roller 53 downward. At the same time, the first adjusting roller 53 also drives the second adjusting roller 54 upward through the connecting rod 52, thereby increasing the path length of the fabric between the two and thus adjusting the tension of the fabric, preventing the fabric from becoming loose and wrinkled due to insufficient tension. Until the fabric tension and the spring force of spring 58 reach equilibrium, the first adjusting roller 53 and the second adjusting roller 54 stop moving, thus achieving adaptive adjustment of the fabric tension and ensuring the flatness of the fabric and the accuracy of the inspection during the fabric inspection process.
