What is the working principle of the automatic hot sealing cold cutting bag machine?

Automatic hot sealing cold cutting bag making machine is a common packaging equipment, widely used in food, medicine, chemical industry and other industries. Its working principle is to achieve the cutting, sealing and molding of plastic film through a series of power systems and control systems.

The working principle of the automatic hot sealing cold cutting bag machine can be divided into the following steps:

1, pull the film: place the plastic reel on the bag making machine, and pull the film from the reel through the tension control system. At the same time, the position and tension of the film are detected by the sensor to maintain the stable tension of the film.

2. Parallel folding: After the film is detected by the sensor, it enters the folding device. The folding device folds the film in parallel at a preset width to form a rectangular shape.

3. Sealing and cutting: the folded film enters the sealing and cutting system. The sealing and cutting system consists of a heating device and a cutting knife. The heating device heats the edge of the film to the sealing temperature through the heating element, then the cutter moves quickly and cuts the film into a bag shape by shear force.

4. Cold cutting: After sealing and cutting, the bag-like film enters the cold cutting system. The cold cutting system rapidly reduces the temperature of the film through the cooling device, allowing it to cool and cure quickly. At the same time, the cold cutting device cuts the bag-like film to the required length to form an individual plastic bag.

5, conveying and stacking: cold cut plastic bags through the conveyor belt to the stacking device. The stacking device will stack the bag-like film according to the preset stacking mode and place it in the specified position.

6, the whole working process, automatic hot sealing cold cutting bag machine through the control system to coordinate the control of each device. The control system adjusts the working speed and strength of each power system according to the preset parameters to maintain a stable working state.

7, automatic hot sealing cold cutting bag machine also has some auxiliary functions, such as automatic counting, automatic alarm, automatic detection. These functions are achieved through sensors and monitoring devices, which can improve the accuracy and efficiency of packaging.

The working principle of the automatic hot sealing cold cutting bag making machine is to process and package the plastic film through the steps of film drawing, parallel folding, sealing and cutting, cold cutting, conveying and stacking. The working process mainly relies on the coordinated control of the power system and the control system to achieve efficient and accurate automatic packaging.
