What types of common metal can sealing machines are there?
​​
(1) The working feature of the semi-automatic can sealing machine is that it is manually capped, and the can is tightly pressed between the head of the can sealing machine and the supporting bottom plate or the lifting plate, and then the can is sealed. There are two types of crimping sealing methods: ① the can itself rotates with the pressure head; ② the can is fixed between the pressure head and the bottom plate and cannot rotate. The latter type is more suitable for sealed juicy cans. Because the can body does not rotate, it can prevent the soup in the can from splashing out under the action of centrifugal force, resulting in insufficient net weight of the product.

(2) There are many types of automatic sealing machines, such as single-head, double-head, four-head, six-head or more fully automatic sealing machines. The more heads, the higher the production capacity. At present, foreign high-speed can sealing machines (such as Ankira 120L can sealing machine made in the United States) can seal cans of various sizes, and the sealing capacity is as high as 1200 cans/min.

(3) The vacuum automatic sealing machine is characterized in that the sealed cans enter the sealing chamber of the sealing machine, and the air in the can is drawn out by the pipeline connected to the vacuum pump, and then sealed. The machine seals when there are cans with lids, automatically stops when there are cans without lids, automatically stops when overloaded, cannot start and automatically stops when the vacuum is insufficient, and other automatic control devices, with a production capacity of 50 cans/min. It is suitable for special-shaped tanks with a maximum diagonal of 130 mm and a tank height of 22 to 96 mm. The can sealing machine has the advantages of simple structure, convenient maintenance and operation, small size and light weight.
