Applications of valve pocket packaging machine in flour industry

At present, the application of valve bags in the flour industry is still relatively small. The main reason is that the cost of valve bags is higher than that of woven bags. Some baking powder, chicken powder, and high-end flour are packaged in valve bags. Now Wuxi Jianlong will tell you in detail that the valve pocket packaging machine is used in the flour industry.

The powder in the silo enters the discharge hopper shell of the valve bag packaging machine. When the bag is manually inserted, the travel switch is activated, the signal is transmitted to the microcomputer, the solenoid valve is activated, the air cylinder works, and the discharge nozzle is opened, and the powder is discharged by the high-speed impeller. The materials are continuously canned and woven bags through the discharge nozzle.

When the bag weight reaches the set amount, the sensor will transmit the signal to the microcomputer, the solenoid valve will be controlled by the microcomputer to start the cylinder, and the discharge nozzle will be closed to stop canning; Loosen to make the woven bag tilt off. The whole filling process is controlled by electrical integration. In addition to manual bag insertion, the opening and closing of the bag press and the discharge nozzle; the filling, weighing, and bag dropping of powder materials can be automatically Finish.

Advantages of valve pockets: moisture-proof, anti-corrosion, one-way ventilation, good sealing, environmentally friendly and degradable, suitable for high stacking, long-distance container transportation, etc. Valve bag packaging machines are widely used in chemical, plastic, dye, paint and other industries, and there are many mature models, ranging from semi-automatic manual bagging to fully automatic automatic bagging and multi-station turntable automatic bagging. Paper-plastic composite valve bag: It is made of plastic woven bag (referred to as base cloth) as the base material and is made by casting method (cloth/film/paper composite is three-in-one);

Kraft paper valve pocket: It is made of kraft paper, (kraft paper is mainly divided into imported kraft paper and domestic kraft paper). The number of layers of kraft paper generally varies from one layer to six layers according to the purpose, and the middle can be coated or added with PE plastic film. PE valve bag: commonly known as weight bag valve bag, made of polyethylene film, the thickness of the film is generally between 8-20 silk.

Low melting point valve bag: made of low melting point polyethylene film, the thickness of the film is generally between 8-20 filaments, suitable for chemical enterprises to use in large-scale production on the assembly line, which can reduce pollution and reduce labor intensity of workers.

Composite valve pocket: It has the printability of paper and the moisture resistance and firmness of plastic. It is a new material. Printing of valve pockets: generally one to four colors, up to eight colors.

The valve bag packaging machine adopts pneumatic conveying and feeding method to complete material packaging, with good environmental protection effect, perfect exhaust system and good sealing performance. The following specifically tells you the working principle of the valve bag packaging machine.

The powder in the silo enters the discharge hopper shell of the valve bag packaging machine. When the bag is manually inserted, the travel switch is activated, the signal is transmitted to the microcomputer, the solenoid valve is activated, the air cylinder works, and the discharge nozzle is opened, and the powder is discharged by the high-speed impeller. The materials are continuously canned and woven bags through the discharge nozzle.

When the bag weight reaches the set amount, the sensor will transmit the signal to the microcomputer, the solenoid valve will be controlled by the microcomputer to start the cylinder, and the discharge nozzle will be closed to stop canning; Loosen and tilt the woven bag off

The whole filling process is controlled by electrical integration. In addition to manual bag insertion, the opening and closing of the bag press and the discharge nozzle; the filling, weighing, and bag dropping of powder materials can be completed automatically.

The above is what Wuxi Jianlong brings to you about the application of valve pocket packaging machine in the flour industry. You are welcome to come to our company for consultation on the demand for valve pocket packaging machine.
