Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging processing, in particular to a molding device for plastic packaging. Background Art

[0002] Plastic packaging is a common necessity in our daily lives, with a wide range of applications, including food packaging, craft packaging, and express delivery packaging. Currently, most packaging box production requires hot pressing of soft raw material sheets for initial forming, allowing them to be formed and released from the mold. After initial forming, the plastic is still relatively hot and has not yet fully set, requiring cooling before the next processing step.

[0003] At present, most plastic packaging molding equipment often uses room temperature cooling to cool and solidify the plastic packaging after initial molding. However, due to the high temperature inside the production workshop, the cooling rate is slow, resulting in unsatisfactory production efficiency. Therefore, those skilled in the art provide a plastic packaging molding equipment to solve the problems raised in the above background technology. Utility Model Content

The excess water mist condenses and falls through the surface of the conveyor belt into the water tank for recycling, so that the device can increase the cooling rate of the preliminarily formed packaging material, thereby improving production efficiency.

[0008] An air pump is installed to draw in and pressurize outside air. The compressed air enters the return air duct through the air inlet pipe. The pressurized air inside the return air duct is blown toward the cooling packaging material through the expander, further accelerating the cooling of the packaging material while removing the water mist on the packaging material surface, further improving production efficiency.

[0019] Furthermore, the return air duct is made of stainless steel;

[0020] According to the above technical solution, the return-shaped air duct is made of stainless steel, which prolongs the service life of the return-shaped air duct.

[0021] Furthermore, the number of the plurality of connection terminals is four, and the four connection terminals and the resistor network form a group with two connection terminals and one resistor network;

[0022] Through the above technical solution, since every two connection terminals and one resistor network form a group, the resistor network can be powered on and used normally.
