[0002] Most textile enterprises are in the state of manual cloth inspection. On ordinary cloth inspection machines, inspectors rely on eyesight to observe and find defects on the cloth surface. Some enterprises use the method of manual cloth turning to inspect the defects on the cloth surface, which has disadvantages such as low detection rate, slow speed, and high labor intensity. In recent years, with the emergence of machine vision intelligent cloth inspection machines, there has been a breakthrough change in the traditional cloth inspection method. Although there are various problems with machine vision intelligent cloth inspection machines at present, machine vision intelligent cloth inspection is gradually replacing manual cloth inspection, and during the cloth inspection process, the cloth needs to be laid flat for transportation.

The rotating gear is meshed with a supporting rack, and the cloth pulling power device includes a cloth pulling motor.

[0007] As a preferred solution, cloth pulling blocks constrained in the longitudinal strip through holes are provided at both lateral ends of the cloth pulling rod, and the cloth pulling rod slides back and forth in the longitudinal strip through holes by manual traction.

[0013] As a preferred solution, the automatic cloth inspection platform is also provided with a lighting lamp group.

[0014] After adopting the above technical solution, the effects of the present utility model are as follows: A coiled material unwinding and cloth pulling device includes a frame. Mounting plates are fixedly installed on both lateral sides of the frame horizontally. Between the mounting plates, at the upstream position, there is an unwinding station for installing an unwinding cloth device. Between the mounting plates, at the downstream position, there is a winding station for installing a winding cloth device. On the mounting plates, between the unwinding station and the winding station, there is a detection station. On the mounting plates at the detection station, a transition roller group for changing the conveying direction of the cloth is rotatably installed. Downstream of the transition roller group, an upstream cloth unfolding device, an automatic cloth inspection platform, a downstream cloth unfolding device, and a manual cloth inspection platform are sequentially arranged and are all installed between the mounting plates. The manual cloth inspection platform is upstream of the winding station. An automatic detection device is arranged above the automatic cloth inspection platform. On the mounting plates at the detection station, there is a longitudinal strip-shaped through hole. The opening height of the longitudinal strip-shaped through hole is higher than the installation height of the automatic cloth inspection platform. A cloth pulling rod is longitudinally slidably installed in the longitudinal strip-shaped through hole. The cloth pulling rod is driven by a cloth pulling power device to reciprocate in the longitudinal strip-shaped through hole; First, a certain length of cloth is unwound at the unwinding station. Then, the cloth is wound around the cloth pulling rod through the transition roller group. Then, the cloth pulling power device drives the cloth pulling rod to move longitudinally, so that the cloth moves from the unwinding station to the winding station. Then, the cloth is conveyed to the automatic cloth inspection platform through the transition roller group. The upstream cloth unfolding device ensures that the cloth on the automatic cloth inspection platform is flat, which is convenient for detecting the quality. Then, the downstream cloth unfolding device ensures that the cloth on the manual cloth inspection platform is flat, further ensuring the detection quality; This cloth pulling device can quickly pull the cloth to complete the traction of the cloth, and at the same time can ensure that the surface of the cloth is flat during the conveying and detection processes, the detection is accurate, and the efficiency is improved.

[0015] Also, since rotating gears are rotatably installed at both lateral ends of the cloth pulling rod, and straight tooth racks corresponding to the longitudinal strip-shaped through holes are arranged on the mounting plates, the rotating gears are meshed with the support racks. The cloth pulling power device includes a cloth pulling motor. The cloth pulling motor is installed on one lateral side of the cloth pulling rod to drive the rotating gear to rotate. The cloth pulling motor moves synchronously with the cloth pulling rod; In this way, by driving the rotating gear to rotate through the cloth pulling motor, it can cooperate with the straight tooth rack, so that the cloth pulling rod can move along the longitudinal strip-shaped through hole to complete the cloth pulling, saving manpower and improving efficiency.

[0016] Also, since cloth pulling blocks that are constrained in the longitudinal strip-shaped through hole are arranged at both lateral ends of the cloth pulling rod, the cloth pulling rod reciprocates in the longitudinal strip-shaped through hole by manual traction; In this way, directly pulling by a single person can further reduce the difficulty of cloth pulling and improve the efficiency.

[0017] Also, since the transition roller group includes a cloth inspection transition roller for traction and transition during cloth inspection and a cloth pulling transition roller for traction and transition during cloth pulling, the cloth pulling transition roller and the cloth inspection transition roller are sequentially installed between the mounting plates; Effectively distinguish the transition rollers used when pulling and conveying the cloth, improving the accuracy of the work.

[0018] Furthermore, since the upstream cloth unfolding device and the downstream cloth unfolding device have the same structure, the upstream cloth unfolding device comprises a laterally extending upstream transverse support rod, and the lateral sides of the upstream transverse support rod are respectively provided with circulating transverse transmission belts, and the transverse transmission belts are driven to rotate by a pulley driving power device, and the transverse transmission belts are respectively transmitted toward the mounting plate close to one side, and auxiliary conveying rollers are provided between the transverse transmission belts; since the transverse transmission belts can continuously perform cyclic transmission, the passing cloth can be unfolded toward the lateral sides, thereby effectively conveying and smoothing, facilitating subsequent detection, and improving the accuracy of detection.

[0019] Furthermore, since the outer array of the transverse transmission belt is equipped with shifting blocks, the leveling effect of the transverse transmission belt is improved.

[0020] Furthermore, since the automatic cloth inspection platform is fixedly mounted between the mounting plates via the cloth inspection bracket, inspection transition rollers rotatably mounted on the mounting plates are provided at both longitudinal ends of the automatic cloth inspection platform, ensuring stable and accurate transportation on the automatic cloth inspection platform and improving the detection accuracy of the automatic cloth inspection platform.

[0021] Furthermore, since the automatic detection device includes a plurality of automatic detection cameras and a lighting group installed around the automatic detection cameras, the automatic detection cameras are fixedly installed in the top cover shell, the automatic detection cameras are arranged horizontally and correspond to the horizontal length of the automatic cloth inspection platform, the top cover shell is fixedly installed on the mounting plate through the detection bracket, and the lighting group is also installed in the top cover shell; the automatic detection cameras can ensure that the cloth in the horizontal direction can be effectively detected, and the lighting group ensures that the cloth can be illuminated for a clearer display.

[0022] In addition, since the automatic cloth inspection platform is also provided with a lighting group, the display is further clear and the detection accuracy is improved. BRIEF DESCRIPTION OF THE DRAWINGS
