Blanking device for food box

Abstract

The invention provides a blanking device for a food box and belongs to the technical field of mechanical equipment. The technical problem that an existing blanking device for the food box is low in efficiency is solved. The blanking device for the food box comprises a base, an upper die and a lower die, wherein the upper die and the lower die are arranged on the base. The lower surface of the upper die is provided with an inwards-concave containing groove for containing the bottom of the food box, the upper die can reciprocate towards the lower die, and an annular upper cutter is arranged on the groove side of the containing groove. The lower die is fixedly arranged on the base, the upper surface of the lower die is provided with an annular lower cutter opposite to the upper cutter, one side of the lower die is provided with a transfer platform capable of vertically moving, and a push block capable of pushing the food box to the space between the upper die and the lower die is arranged on the transfer platform. The blanking device has the advantages of being high in blanking efficiency and side cutting precision and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a food box processing equipment, in particular to a food box punching device. Background technique [0002] In recent years, food boxes on the market have been made from foam materials to environmentally friendly materials, usually by injection molding or blister molding. The efficient and continuous production of automated equipment makes the initial product of injection molding or blister molding a combination of several Yes, the separation of individual products needs to be achieved by punching and blanking. Each food box has several food troughs for containing food. These food troughs form protrusions at the bottom of the food box. Two adjacent food Grooves are formed between the protrusions of the box, and arc-shaped flanges that are folded down are also designed around each food box. [0003] Our patent (notification number: CN104552434A; announcement date: 2015...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned patents, when cutting the edge of the product, the first manipulator is used to feed the material, and the action is carried out by clamping. The structure of the manipulator is complicated, and there are many actions to be completed, and the efficiency is low.

In addition, the food boxes in the above-mentioned patents are all placed in the forward direction when punching, and the arc-shaped flanging is not easy to maintain stability and accuracy when cutting. The precision requirements for the tool of the mold are high, and the thickness of the tool is generally thin and easy to damage. Moreover, the defective rate of punched food boxes is high, which also indirectly affects production efficiency
