Description

TECHNICAL FIELD

[0001] The utility model relates to paper box production equipment, concretely relates to a short side plate edge folding transfer mechanism of paper box machine. BACKGROUND

[0002] The paper box machine is mainly used for the automatic production operation of various paper boxes. One kind of paper box machine adopts three paperboards to be combined into a paper box. The paperboard includes two short side plates and one middle paperboard. In the production process, the short side plate needs to be edge folded by the edge folding transfer mechanism. A three-piece paper box forming machine short side wall edge folding device is disclosed in Chinese patent document (publication number: CN 218660687 U; publication date: March 21, 2023), which includes a forming lower die installed on a rack, an upper die arranged above the forming lower die and movable up and down relative to the forming lower die, and a box body paper conveying mechanism arranged in front of the forming lower die for conveying box body die-cutting paper to the forming lower die. Its feature is that it further includes symmetrically arranged short side wall paper conveying mechanisms above both sides of the forming lower die and an edge folding mechanism. The short side wall paper conveying mechanism includes a conveying belt, a paper moving assembly arranged at the output end of the conveying belt, and limiting elastic sheets arranged above both sides of the output end of the conveying belt. The edge folding mechanism is located below the conveying belt and includes an edge folding plate pushed by an edge folding cylinder. The paper moving assembly includes a movable suction cup for sucking and releasing the frontmost short side wall die-cutting paper sample at the output end of the conveying belt to the support plate in front of the edge folding plate. When the edge folding plate is moved forward, the short side wall die-cutting paper sample in front of it is pushed along the support plate to the upper die to make the short side wall die-cutting paper sample board face adhere to the vertical wall of the upper die corresponding to the short side wall die-cutting paper sample. At the same time, at least one end of the short side wall die-cutting paper sample is folded inward to adhere to the corresponding side wall of the upper die. The upper die side wall upper part is equipped with a push block, and there is a gap L between the front end of the support plate and the corresponding vertical wall of the upper die.

[0003] The defects of the above structure are: the overall structure is relatively complex, especially the paper moving assembly and the edge folding mechanism are arranged very close, which is troublesome for production assembly and disassembly and maintenance; in addition, the short side wall paper is bent after being sent out from the limiting elastic sheet, which affects the bending quality of the subsequent paperboard, and the paperboard will naturally fall off during conveying, which easily causes the position of the paperboard to deviate, thereby affecting the edge folding forming quality.
