In the domestic market, there are mainly three types of bag making, bag feeding and tank feeding. For you to analyze the differences and characteristics of these three packaging machines.
The bag-type automatic packaging machine is usually composed of a bag making machine and a weighing machine. The weighing machine can be either a weighing type or a screw type, and the granule and powder materials can be packaged.
The machine is an automatic packaging equipment for directly forming a packaging film and performing measurement, filling, coding, cutting and the like in the bag making process. The packaging material is usually a plastic composite film, an aluminum-platinum composite film, a paper bag composite film, etc. It is characterized by high degree of automation, high price, good image and good anti-counterfeiting. It is suitable for small-size and high-volume automatic packaging of washing powder, seasonings, puffed foods, etc. The disadvantage is that it is not convenient to change the packaging specifications.
The bag type automatic packaging machine is usually composed of two parts: a bag feeding machine and a weighing machine. The weighing machine can be either a weighing type or a screw type, and the granule and powder materials can be packaged. The working principle of the machine is to use the robot to take the bag, open the bag, bag and seal the user's pre-made bag, and at the same time complete the filling, coding and other functions under the coordinated control of the microcomputer, thereby realizing the automatic packaging of the pre-made bag. Its characteristic is that the robot replaces the artificial bagging, which can effectively reduce the bacterial contamination 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. The disadvantage is that the pre-made bag needs to remove static electricity, otherwise it is easy. Take double bags and open bags are not allowed. It is also not convenient to change the packaging specifications of this machine.
The automatic tank 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 tank feeding machine generally adopts an intermittent rotating mechanism, and each time one station is rotated, a weighing signal is sent to the weighing machine to complete a quantitative canning. The weighing machine can be either weighing or screw type, and the granule and powder materials can be packaged. The capping machine is connected to the canning machine through a conveyor belt, and 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, malt extract, 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.
