Description

Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to an automatic unwinding mechanism for bag making machines. Background Art

[0002] A bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products. Patent No. CN201921157625.3 discloses a fully automatic garbage bag making machine. A tension roller is added to the traction roller, which can stretch the garbage bag flat to avoid wrinkles that affect the normal winding of the garbage bag. In addition, the speeds of the front motor and the rear motor are different, and the speed of the rear motor is faster than that of the front motor, which is used to overcome the friction of the garbage bag on the multi-channel transmission roller, avoid inconsistent transmission speeds of the front and rear channels of the garbage bag, ensure that the tension of the garbage bag is constant, and avoid uneven wrinkles. However, since the discharge device at the feeding end of the bag making machine itself does not have a corresponding power structure, the material placed in the discharge structure needs to be discharged under the traction of the traction control structure, and the garbage bag raw material is relatively fragile, which causes the raw material placed on the periphery of the material roller inside the discharge device to be easily stretched and deformed due to tension, which is easy to have a certain impact on the quality after manufacturing. Therefore, we propose an automatic unwinding mechanism for a bag making machine. Utility Model Content
