Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloth production equipment, and particularly relates to an automatic cloth hanging machine. BACKGROUND

[0002] After cloth production, the cloth generally needs to be printed with patterns to improve the competitiveness of the products, such as blankets, towels and the like. After the pattern printing is completed, the cloth needs to be quickly dried to prevent the seepage of free water in the color paste and the mutual color mixing of the color paste due to wetting. After the drying of the cloth, the cloth needs to be transported to a steaming and fixing process and steamed in the steaming and fixing process. After the drying of the cloth, the cloth is usually hung on a cloth hanging frame to realize the transportation of the cloth and the subsequent steaming and fixing treatment. At present, the cloth hanging operation of the cloth on the cloth hanging frame is usually completed by manual operation. Since the cloth is cut after the fixing process is completed, the dried cloth is integrated and long. The manual cloth hanging operation is not only complicated and inconvenient, but also low in efficiency and high in labor intensity. In addition, the cloth hanging quality cannot be guaranteed, and the cloth hanging is not uniform, which causes the cloth to be pasted together. If the cloth hanging operation is not proper, the cloth hanging is not flat and wrinkles appear, which finally causes the color mixing and color mixing of the cloth and affects the quality of the cloth. The qualified rate of the cloth is low. CN206511559U and CN211169119U both disclose a cloth hanging machine capable of automatic operation. However, the cloth hanging machine cannot complete the position change of the cloth hanging rod because the cloth hanging vehicle needs to keep moving forward during the cloth hanging process. Since the color paste has not been fixed during the movement of the cloth, the cloth is often dyed together during the position change. In addition, the cloth pressing mechanism in CN206511559U uses a downward pressing cloth hook. Due to the deviation of the cloth pressing position or direction, the cloth pressing force is not enough, and the cloth is easily slipped and damaged. In order to solve the above technical problems, a synchronous automatic cloth hanging machine is developed to solve the above technical problems. SUMMARY
