Description

Technical Field

[0002] Bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products.

The thickness detection mechanism of the bag making machine works by the fan arranged on the discharge channel, and transmits the wind to the air outlet through the connecting pipe, so as to cool down the bags just produced from the bag making machine body, and prevent the bags from being deformed during production. The bag making machine is started by the electric push rod, and the height of the air outlet is adjusted by the mounting plate, so that the air outlet can cool down the bags at the most suitable height. The reel motor arranged on the discharge channel is started to drive the second rotating shaft to rotate, and the second rotating shaft drives the reel to rotate, so as to roll up the bags produced by the bag making machine body. However, in the above device, the discharge channel, the fan, the electric push rod and other components cooperate with each other, so it is difficult to achieve the effect of fixing the bag making machine, and it is difficult to ensure that the bag making machine reaches the required precise thickness requirements during the production process, and it needs to be improved.
