Description

Technical Field

[0001] The utility model relates to the field of carton packaging machinery, in particular to a folding and forming tool assembly in a carton forming machine. Background Art

[0002] During the forming process of cartons, especially paper food boxes, processes such as die cutting, indentation, folding, and bonding are required. Among them, the folding process is to fold and combine a relatively thin fold-resistant cardboard after die cutting and indentation. The folding process requires a kind of tool. Due to the mismatch of shape and material, the traditional hook-shaped folding tool has poor contact with the paper crease, and will break and damage the paper to be folded, resulting in a low yield. And the traditional hook-shaped folding tool is inconvenient to replace. Usually made of metal, it is easy to break the paper, resulting in a low yield and waste. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the defects existing in the prior art and provide an improved carton folding and forming tool, which can adapt to the folding and forming processes of different cartons and realize the functions of quickly replacing and adjusting the tool.

Its characteristics are that: the tool head and the tool handle are connected by a rotary fastening component, and the tool head includes at least two blade shapes;

[0005] For more convenient adjustment, the technical solution provided by the utility model is to integrate two or more blade shapes onto one tool head;

[0006] Further, the blade shape includes a straight knife;

[0007] Further, the blade shape includes an arc knife.

[0008] For the quick replacement of the blade shape of the tool head, the technical solution provided by the utility model is to connect the tool head and the tool handle through a rotary fastening component;

[0009] Further, the rotary fastening component is composed of an engaging part, a rotating shaft, a handle, an eccentric wheel, and a connecting rod. The handle and the eccentric wheel are an integral component. One end of the connecting rod is connected to the eccentric wheel through the rotating shaft, and the other end is fixed on the tool handle. An engaging part is opened on the contact surface between the tool handle and the tool head. When the handle is toggled, the eccentric wheel will squeeze the tool handle, and then tighten the connecting rod, and the engaging part between the tool handle and the tool head is locked to fix the tool head.

[0010] Further, the rotary fastening component is composed of a special-shaped through hole opened on the tool head and a special-shaped pin for an adapted through hole;

[0011] Further, the shaped through-hole is a regular polygon, and the number of sides of the polygon is equal to the number of blade shapes.

[0012] To adapt to different folding angles required for the folding and forming of the paper box, the technical solution provided by the present utility model is that a through groove is provided at the outer edge of the tool head of the paper box folding and forming tool assembly; a rubber layer is provided outside the through groove, and a convex portion is provided on the rubber layer. The convex portion can cooperate with the through groove to combine the rubber layer and the tool head into one body.

[0013] Further, the rubber layer can be replaced through the through groove with a rubber layer having a different cross-sectional shape.

[0014] Further, the cross-sectional shape of the replaced rubber layer is adapted to the angle required by the paper box forming process.

[0015] The advantages and beneficial effects of the present utility model are as follows: The tool head integrates different blade types, and different tool types can be quickly adjusted by rotating the fastening member; through the design of the through groove and the convex portion, rubber layers with different cross-sectional shapes can be replaced to adapt to different angles required for the folding of the paper box; thus, it better meets the requirements of the paper box forming production line, can effectively prevent the paper to be folded from being broken, and improves the finished product rate and production efficiency.
