Working Principle Of Bag Making Machine

1. Working principle of bag making machine

Bag making machine is a machine that makes plastic film into bags. Its main principle is to roll the film material inside the machine, go through multiple processes such as conveying, sealing, and bag cutting, and ultimately produce bags that meet user needs.

2. Structure composition of bag making machine

1. Bag conveying system

The bag conveying system is the fundamental element of the bag making machine, which can roll plastic films one by one from the winding shaft and transport them to the next station through the conveyor belt. In order to ensure the transmission effect, conveyor belts usually use conveyor belts or rollers. In addition, the bag conveying system can also be equipped with sensors to ensure the accurate position of the bag during transportation.

2. Sealing system

The sealing system is one of the important components of the bag making machine. Its main function is to heat the plastic film to a certain temperature, melt it, and seal it into a bag through pressure. Common sealing methods include hot sealing, cold sealing, radio frequency sealing, etc. The scope of application of different sealing methods also varies.

3. Bag cutting mechanism

The bag cutting mechanism is an important component of the bag making machine that can complete bag production. It can cut plastic film into the required bag length and perform processing such as punching and hanging holes when necessary. There are various types of common bag cutting mechanisms, such as knife type, rotary type, and hot cutting type, which can be selected according to user needs.

3. Application fields of bag making machines

Bag making machines are widely used in various fields such as food, medicine, chemical industry, logistics, etc. Among them, in the food industry, bag making machines are mainly used to produce various food bags, including biscuit bags, snack bags, instant noodle packaging bags, etc; In the pharmaceutical field, bag making machines are used to manufacture pharmaceutical packaging bags and reagent bags, etc; In the chemical and logistics industries, bag making machines are mainly used to produce various chemical bags, sealed bags, mail bags, etc.

The above is an introduction to the basic knowledge of bag making machine principles. There are various types of bag making machines, and different types of bag making machines have different purposes and principles. If you need to choose a bag making machine that suits you, please choose according to your own needs.
