The invention relates to a tension deviation rectification device for a bag making machine, in particular to a device for rectifying deviation of folded films, and belongs to the technical field of bag making machines. The tension deviation rectification device comprises a left supporting plate and a right supporting plate, the left supporting plate is fixed onto a left body wall plate, the right supporting plate is fixed onto a right body wall plate, a long circular left adjusting hole is formed in the left supporting plate, and a left slider is slidably mounted in the left adjusting hole. The left supporting plate is connected with a left adjusting screw in a threaded manner, and the lower end of the left adjusting screw is connected with the left slider. A long circular right adjusting hole is formed in the right supporting plate, and a right slider is slidably mounted in the right adjusting hole. The right supporting plate is connected with a right adjusting screw in a threaded manner, and the lower end of the right adjusting screw is connected with the right slider. Two movable rollers are jointly connected between the left slider and the right slider, vertically distributed and mutually parallel. The positions of an upper film and a lower film can be adjusted to align patterns, front and back misplacement of the two films is prevented, product quality is improved, and cost is low.
Description
technical field [0001] The invention relates to a tension correction device of a bag-making machine, in particular to a device for correcting the deviation of a folded film, and belongs to the technical field of bag-making machines. Background technique [0002] The bag making machine generally includes several processing devices, which are connected and driven by the driving mechanism, so as to realize the processing of plastic films into plastic bags. [0003] The single-layer film for bag making is cut into two layers after being folded in half before longitudinal ironing. The upper and lower layers of the film need to be aligned in pattern. During this process, position deviation will occur, and the front and rear of the two layers of film may be misaligned, thus affecting product quality. Contents of the invention [0004] The purpose of the present invention is to overcome the above disadvantages, thereby providing a tension correction device for bag making machines...
