Folding and cutting integrated machine for valve bag

Abstract

The invention relates to a folding and cutting integrated machine for a valve bag. The folding and cutting integrated machine comprises a rack, wherein a folding mechanism for folding a bag body at anoriginal bag opening and a cutting mechanism for carrying out one-word cutting to the folded bag body at the folding mechanism are arranged on the rack, the rack is provided with a cutting placing surface for placing the valve bag at the cutting mechanism, the cutting mechanism comprises a cutter and a cutting drive mechanism for driving the cutter to conduct a cutting movement along the cuttingplacing surface, and the cutter is provided with a one-word extending mechanism in the cutting placing surface. By adopting the above scheme, the folding and cutting integrated machine for the valve bag, which can fold the bag body by the folding mechanism so that two cutting sides needing reverse L-shaped cutting are overlapped, and cut single by the one-word blade in the cutting mechanism to realize flat cutting side and simplified process, is provided.

Description

technical field [0001] The invention relates to the technical field of valve pocket production, in particular to an integrated machine for folding and cutting valve pockets. Background technique [0002] As a kind of packaging bag, the valve bag is often used in the industry to pack cement powder, flour and other materials. It feeds from the top or bottom valve port, and has the advantages of neat stacking, beautiful appearance, high packaging efficiency, convenient transportation, and low damage rate. . [0003] Existing valve pockets are usually made of figure 1 , figure 2 The bag body shown is used as a product to be processed, and one end of the bag body is provided with an original bag mouth, and then image 3 , Figure 4 As shown, by cutting the bag body at the mouth of the bag, a 7-character cutting will be made to cut the next piece of cutting waste in a square shape, so that the bag body will form a cut pocket mouth and the bag body will be located between the ...

AI Technical Summary

Problems solved by technology

[0004] The problem with the existing valve pockets is that the 1.7-shaped cutting needs to be cut horizontally and vertically twice, so the production efficiency is low due to too many cutting times; the 2.7-shaped cutting is easy to cut in the horizontal and vertical Excessive cutting at the intersection of cuts leads to damage to the bag body, resulting in insufficient strength of the bag body or insufficient cutting so that the cutting waste is connected to the bag body and affects subsequent processing
