Printing device for woven bag production

Abstract

The utility model discloses a printing device for woven bag production, relates to the technical field of woven bag processing, and aims to solve the problems that when an existing printing device for woven bag production is used for winding a woven bag, traction force acting on the woven bag can be changed due to a mechanical structure and manual operation of the device, and the woven bag is difficult to roll. When the traction force is large, the woven bag is deformed and even damaged, and when the traction force is small, the woven bag is wound and loosened, and the product quality is affected. By arranging the woven bag buffer roller, tension acting on the woven bag is reasonably controlled, so that the tension is kept in a proper range, when traction acting on the woven bag is increased, the woven bag buffer roller moves downwards to relieve the increased traction, and when the traction acting on the woven bag is reduced, the woven bag buffer roller moves upwards to relieve the increased traction. And the woven bag is tightened, so that the tension stability is ensured.
