A high-speed thick packaging film bag making machine

Abstract

The invention discloses a high-speed thick package film bag making machine, which comprises an air expansion shaft, a clamping motor, an ironing corner mechanism, a cooling air mechanism, an ironing cutter mechanism, a cutter mechanism, a water circulating cooling mechanism, a conveying motor, a conveying mechanism and a programmable logic control mechanism, wherein the ironing corner mechanism, the cooling air mechanism, the ironing cutter mechanism, the cutter mechanism and the water circulating cooling mechanism are sequentially connected with the working surface of the bag making machine. The high-speed thick package film bag making machine is characterized in that the working surface of the ironing cutter machine is higher than the working surface of the ironing corner mechanism, a rubber roll servo motor is arranged at the right side of the working surface of the ironing cutter mechanism, and is used for driving a pressing rubber roll to convey a to-be-processed film bag to the fixing position of the ironing cutter mechanism for seam ironing, the film bag after the seam ironing by an ironing cutter vertically falls onto the water circulating cooling mechanism and the working surface of the cutter mechanism along the tail end of the right side of the ironing cutter mechanism under the action of gravity, and the conveying motor drives the conveying mechanism to continuously work when the package film bag making machine starts to work. The package film bag making machine has the advantages that the production efficiency is improved by two times, and the seam ironing strength of the film bag is improved by five times.

Description

technical field [0001] The invention relates to a bag making machine on an automatic filling line in the chemical industry, in particular to a high-speed thick packaging film bag making machine. Background technique [0002] A 25kg three-layer co-extruded thick film bag used in the automatic filling line of the chemical industry has high requirements on the heat sealing of the bottom of the bag, and requires both sides of the bottom of the bag to be ironed firmly. The traditional production of thick film bags The technology is to paste Teflon tape on the middle two layers of the ironing knife, use a blower to cool the film bag after the heat-sealing knife, use rubber rollers to transport the scalding angle and the film bag after heat-sealing the ironing knife, and use slow Slow ironing, slow cooling, the method of transporting after the heat seal is cooled, this method is not only slow in speed and low in output, only 8 bags can be ironed per minute, but also the quality can...

[0002] A 25kg three-layer co-extruded thick film bag used in the automatic filling line of the chemical industry has high requirements for the heat sealing of the bottom of the bag, and requires both sides of the bottom of the bag to be ironed firmly. The traditional production of thick film bags The technology is to paste Teflon tape on the middle two layers of the ironing knife, use the air blower to cool the film bag after the heat sealing of the ironing knife, use the rubber roller to transport the film bag after the heat sealing of the ironing angle and the ironing knife, and use slow Slow ironing, slow cooling, the method of transporting after the heat seal is cooled, this method is not only slow in speed and low in output, only 8 bags can be ironed per minute, but also the quality cannot be guaranteed, the four layers are not bonded firmly, and it is easy to Burnt or stretched at the hot seal

[0003] As a result, the first generation of FFS thick packaging film bag making machine was produced. The first generation of FFS thick packaging film paper bags used servo motors to drive a set of pressing rubber rollers to transfer the processed film bags between the ironing angle mechanism and the ironing knife mechanism. In addition, the cooling water circulation is adopted to cool the film bag after the ironing knife mechanism is ironed, and the cooling and ironing knife structure cutting are carried out at the same time, which improves the production efficiency of the film bag to 18 pieces per minute, and the efficiency of the film bag has also been improved. However, for large-scale production of thick packaging film bags, the production speed of film bags is still low and the efficiency is not high enough. Therefore, we have improved it on the basis of the first generation of FFS thick packaging film bag making machine, so that Its production efficiency is higher
