There are three kinds of automatic packaging machines in the domestic market: bag making, bag feeding and pot feeding. To analyze the difference and characteristics of the three packaging machines.
The bag type full automatic packing machine is usually made up of two parts of bag making machine and weighing machine. The weighing machine can be weighed or screw type, and all the particles and powder materials can be packed.
The machine is the automatic packing equipment that makes the packing film direct bag making, and completes the automatic packing equipment of measuring, filling, making code and cutting off in the process of making bags. The packing material is usually plastic composite film, aluminum platinum composite film, paper bag compound film and so on. It is characterized by high automation, high price, good shape, good anti-counterfeiting, and suitable for washing powder. The small size and large number of automated packaging of condiments, puffed foods and so on, the drawback is that changing the packaging specifications is not very convenient.
The bag type automatic packing machine is usually made up of two parts of the bag feeder and the weighing machine. The weighing machine can be a weighing type or a screw type. All the particles and powder materials can be packed. The working principle of the machine is to use the manipulator to take the bag, bag, bag and seal of the prefabricated bag of the user, and complete the function of filling and making the code under the coordinated control of the microcomputer, so as to realize the automatic packing of the prefabricated bag. It is characterized by the replacement of the manual bag by the manipulator, which can effectively reduce the bacterial contamination in the packaging, and improve the automation level. It is suitable for the small size and large volume automatic packaging of food and seasoning products. The shortcoming is that the prefabricated bag should be removed from the static electricity. Otherwise, it is easy to take the double bag and open the bag. It is not convenient for the machine to change the packing specification.
The automatic packaging machine is mainly used for automatic canning of cup - like containers such as iron cans and paper cans. The whole machine is usually made up of three parts: the tank feeder, the weighing machine and the upper cover machine. The tank feeder generally adopts intermittent rotating mechanism, which sends a blanking signal to the weighing machine at every rotation station to complete a quantitative canning. The weighing machine can be either a weighing or a screw type, and particles and powder materials can be packed. The upper cover machine is connected with the delivery machine through the conveyor belt. The two are essentially single machine linkage, and the work is independent of each other. The machine is mainly used for automatic packaging of chicken essence, chicken powder, milk powder, milk powder and so on. It is characterized by high automation, less pollution, high price, high efficiency and good image. The disadvantage is that it is not convenient to change the specifications.
In addition, there are sealing and contracting equipment, filling and locking machine, ball machine, labeling machine and special packaging equipment, such as the Qingdao three field mask machine, and eye film agent all belong to the packaging machine category. Let's have a detailed understanding of the characteristics and applications of these packaging machines.
