Adjustable flanged plate used for making accordion pockets

Abstract

The invention relates to an adjustable flanged plate used for making accordion pockets. The adjustable flanged plate is characterized by comprising a first tetrahedron and a second tetrahedron which are symmetrical; in the first tetrahedron, the bottom edge of a first triangular plane is connected with the bottom edge of a fourth triangular plane, a second triangular plane and a third triangular plane are connected between two side edges of the first triangular plane and two side edges of the fourth triangular plane, and the connecting edge of the second triangular plane and the third triangular plane is perpendicular to the bottom edge of the first triangular plane; in the second tetrahedron, the bottom edge of a fifth triangular plane is connected with the bottom edge of an eighth triangular plane, a sixth triangular plane and a seventh triangular plane are connected between two side edges of the fifth triangular plane and two side edges of the eighth triangular plane, and the connecting edge of the sixth triangular plane and the seventh triangular plane is perpendicular to the bottom edge of the fifth triangular plane. By the adjustable flanged plate, yield of the accordion pockets can be increased, and production cost is lowered.

Description

technical field [0001] The invention relates to a packing flap, in particular to an adjustable flap used for making organ bags, and belongs to the technical field of packaging molds. Background technique [0002] In many flexible packaging companies, organ bags are almost always involved. When making organ bags with ordinary sheet material composite films, they are usually completed on the center-seal bag-making machine. material cannot be produced. Therefore, a kind of folding machine for making barrel material came into being. However, the molds used to make organ bags from barrel materials in the market are all custom-made edge folding sizing devices according to the actual size of the organ bag. There are many disadvantages in the production process. For example, when the material width deviation is large, it is difficult to ensure the alignment of the folded edges. Especially, the edge of the bag folded out by the large width of the drum will produce many folds. Since ...

Therefore, a kind of folding machine for making barrel material came into being. However, the molds used to make organ bags from barrel materials in the market are all custom-made edge folding sizing devices according to the actual size of the organ bag. There are many disadvantages in the production process. For example, when the material width deviation is large, it is difficult to ensure the alignment of the folded edges. Especially, the edge of the bag folded out by the large width of the drum will produce many folds. Since the size of the folded shaper is fixed, it cannot be adjusted. , so that the slight deviation in the size of the raw material will cause a very large loss
