High -speed bag making machines are suitable for high -density polyethylene (HDPE), low -density polyethylene (LDPE), tube strong and printing plastic film materials, and carried out hot -sealed bags.
The process of high -speed bag mechanisms usually has several main functions, including material feeding, sealing, cutting and code bags.
In the feeding part, the flexible packaging film feed on the roller is opened by a feeding roller. The feeding roller is used to move the film in the machine to perform the required operation. The feeding is usually intermittent operation, such as sealing and cutting other operations during the stop delivery period. The roller is used to maintain the constant tension on the film roll. The feeder and roller are used to maintain tension and key feeding accuracy.
In the sealing part, the temperature -controlled sealing element is moved to the specific time of contact with the film, so that the material is appropriately sealed. The sealing temperature and sealing duration variety according to the type of material, and must be kept constant at the speed of different high -speed bag making machines. The configuration of the sealing element and the related machine format depend on the sealing type specified in the bag design. In most machine operation forms, the sealing process is accompanied by the cutting process, and these two operations are performed when the feeding is completed.
During the operation of cutting and code bags, operations such as sealing are usually performed during the non -feeding cycle of the machine. Similar to the sealing process, the operation of cutting and code bag also determines the suitable high -speed bag making form. In addition to these basic functions, the execution of additional operations such as zipper, pore bags, handbags, anti -destruction sealing, bag mouth, hat crown treatment may depend on the design of the packaging bag, and the attachments connected to the basic machine are responsible for implementing this. Class additional operation.
