Abstract

The invention discloses a cement bag opening and folding device of a cement bag folding machine. The cement bag folding machine comprises a frame. The cement bag opening and folding device is mounted on the frame. The cement bag opening and folding device comprises an upper opening unit, a lower opening unit and a folding unit. The cement bag opening and folding device of the cement bag folding machine is simple in structure, light, quick and capable of overcoming the deficiency of infirm pneumatic suction due to air leakage of unsealed cement bags and meeting the requirements of continuous automatic production.

Description

technical field [0001] The invention relates to a cement bag opening and folding device on a cement bag folding machine. It can automatically open the cement bag, clamp and fix the opened cement bag, and then fold the cement bag according to the folding requirements. After the folding is completed, the crease is pressed to complete the folding work. Background technique [0002] Before sewing the cement bag, it is necessary to do some folding work on the seal of the cement bag mouth, in order to strengthen the strength of the cement bag seal and reserve the cement filling port. To strengthen the sealing strength of the cement bag, it is necessary to fold the reserved part of the cement bag mouth into the cement bag to form an inner lining; the formation of the cement bag filling mouth is to fold a corner of the cement bag mouth into the cement bag to form an oblique angle, and complete the above folding work The cement bag is then sewn and sealed. [0003] Usin...
