The role of the pressure head of the sealing machine

The main function of the pressure head of the can sealing machine is to fix the position of the can body and the lid, so that the can body is in a fixed position when the roller is crimped and pressed tightly. The size of the indenter should be selected according to the diameter of the can. The indenter should be standardized, and the size cannot be changed at will to ensure the standard of the inner diameter of the can and the lid. Generally, the outer diameter of the indenter should be slightly larger than the outer diameter of the mold core on the can lid and have a positive tolerance (negative tolerance is not allowed), but the buckle is inclined upward to an angle of 4°C. If the indenter is too large, the empty can is not easy to fall after sealing; If it is too small, it will cause defects such as friction and slippage of the can lid, which can easily scratch the lid surface and cause the can to rust, or cause uneven sealing tightness.
