Semi-automatic can sealing machine：
The semi-automatic can sealing machine generally consists of a manual can sealing machine, a pneumatic

can sealing machine, an electric can sealing machine and so on. Generally suitable for small business

production, single-piece production, small batch production factories.
a, hand canning machine
The hand-operated can sealing machine is the most widely used semi-automatic can sealing machine. Due

to the advantages of stable mechanical quality and easy debugging, it is widely used by large and

small factories, small workshops, stall shops and other units.
The sealing principle of this model is simple. It adopts two-knife folding and pressing sealing. The

first knife is a folding knife, and the second knife is a bending fastening knife. It is generally

used for the sealing of non-vacuum and inflatable cans.
principle:
1. Put the jar with lid on the bottom support.
2. Step on the pedal to press the jar tightly on the upper mold.
3. Pull the handle to make the first knife and the second knife roll the lid quickly.
4. Put down the pedal and output the finished product.

b, Pneumatic sealing machine:
This model has a slightly higher degree of automation than the hand-held can sealing machine. Two air

cylinders are used to replace the manual arm and pedal respectively.
principle:
1. Put the jar with lid on the bottom support.
2. Step on the foot switch, the bottom support cylinder will push the jar tightly on the press mold.
3. The swing arm cylinder swings to make the first knife and the second knife roll the lid quickly.
4. Finished product output.

c, electric can sealing machine:
The difference between the electric can sealing machine and the lever and pneumatic is that the first

knife and the second knife are installed on both sides of the die.
principle:
1. Put the jar with lid on the bottom support.
2. Step on the foot switch or the can induction switch (different from manufacturers, and the method

is different), the bottom support relies on the motor cam to drive the bottom support to press the can

against the mold.
3. Due to the action of the side swing arm cam, the first knife first presses the cover curling. When

the cam rotates for half a turn, the second knife swing arm begins to press tightly.
4. Finished product output.
The above-mentioned models are semi-automatic can sealing models that are popular in China, and the

average can sealing speed of the models is between 15-30 cans/min. Because of the low cost, low

technical content, and stable quality, many individuals and units use this type of model. The

disadvantage is that it is not suitable for mass automated production lines.
