Problems solved by technology

However, the total length of the bag making machine is 18M, and it is continuous high-speed production. Therefore, from the off-line inspection of the deviation of the built-in stickers at the bag opening to the adjustment of the ironing knife and stickers, and then to re-checking the deviation of the stickers, the workpiece (composite film) has to be removed. It takes a certain amount of time for a long distance, during which a lot of waste products will be generated, especially when the composite film has quality defects such as swaying, there are more waste products, which greatly reduces the yield

Abstract

The invention provides a tracking and deviation rectifying device for a built-in sticking strip of a middle seal bag of a bag making machine. In the operating process of the bag making machine, automatic tracking and deviation rectifying of a hot knife and the sticking strip are achieved. The device is high in degree of automation, is good in deviation rectifying effect, ensures product quality and improves the bag making efficiency. The bag making machine comprises a middle seal hot knife, a horizontal linear guide rail pair and a vertical downwards pressing transmission mechanism; the two ends of the middle seal hot knife are connected with the horizontal linear guide rail pair; the two ends of the horizontal linear guide rail pair are connected with the vertical downwards pressing transmission mechanism; the tracking and deviation rectifying device comprises a movable horizontal shaft, a sticking strip guide board and a photoelectric sensor; the movable horizontal shaft is parallel with the horizontal linear guide rail pair and provided with a guide column base, the sticking strip guide board and the photoelectric sensor; a guide column is vertically arranged on the guide column base and sleeved with a linear bearing pedestal vertically moving along the guide column; the linear bearing pedestal is installed on a connection board; the connection board is connected with the middle seal hot knife; the sticking strip guide board and the photoelectric sensor correspond to the middle seal hot knife in position.

Description

technical field [0001] The invention relates to an automatic tracking and deviation correction device with built-in stickers for sealing bags in a bag making machine, which belongs to the field of packaging machinery. Background technique [0002] The center seal bag adopts the center seal or partial center seal with built-in tape structure. Compared with the traditional center seal bag, it has the advantages of flat center seal, high heat sealing strength, high drop height and high stacking height. Authorized Patent (patent number: ZL 2012 20516834.4), the sticker is set on the side of the bag body, and the sticker is connected to the two sides of the bag by heat sealing (see Figure 7 ). The quality of the back-sealing strip weld is the key to the strength of the strip bag. Since the middle seal bag is made by flat film gradually bending and folding, therefore, the formation of the middle seal edge on the bag making machine has to go through a long distance, and the middl...
