There are three main types of automatic packaging machines: bag-making, bag-feeding, and can-feeding. The differences and characteristics of these three packaging machines are analyzed separately below.
1. The bag-making automatic packaging machine is usually composed of two parts: a bag-making machine and a weighing machine. The weighing machine can be a weighing type or a screw type. Granules and powder materials can be packaged.
This machine is an automatic packaging equipment that directly makes packaging film into bags, and completes the actions of measuring, filling, coding, cutting, etc. during the bag making process. The packaging materials are usually plastic composite films, aluminum-platinum composite films, paper bag composite films, etc. , is characterized by high degree of automation, high price, good image, and good anti-counterfeiting. It is suitable for small-sized and large-scale automatic packaging of washing powder, condiments, puffed food and other products. The disadvantage is that it is not convenient to change the packaging specifications.
2. The bag-feeding automatic packaging machine is usually composed of two parts: a bag-feeding machine and a weighing machine. The weighing machine can be a weighing type or a screw type. Granules and powder materials can be packed. The working principle of this machine is to use the manipulator to take out, open, cover and seal the user's prefabricated bags, and at the same time complete the functions of filling and coding under the coordinated control of the microcomputer, so as to realize the automatic packaging of prefabricated bags.
Its characteristic is that the manipulator replaces the manual bagging, which can effectively reduce the bacterial pollution in the packaging process, and at the same time improve the automation level. It is suitable for small-scale and large-volume automatic packaging of food, condiment and other products. It is not allowed to take double bags and open bags. It is also not very convenient to change the packaging specifications of this machine.
3. The can-feeding automatic packaging machine is mainly used for automatic canning of cup-shaped containers such as iron cans and paper cans. The whole machine is usually composed of three parts: a can feeding machine, a weighing machine and a capping machine.
The can feeding machine generally adopts an intermittent rotating mechanism, and every time a station is rotated, a feeding signal is sent to the weighing machine to complete a quantitative canning. The weighing machine can be a weighing type or a screw type, and both granular and powder materials can be packed.
The capping machine is connected to the can feeding machine through a conveyor belt, and the two are essentially single-machine linkage and work independently of each other. This machine is mainly used for automatic packaging of chicken essence, chicken powder, malted milk essence, milk powder and other products. It is characterized by high degree of automation, less pollution, high price, high efficiency and good image. The disadvantage is that it is not convenient to change specifications.
