Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic packaging box production, especially to a cooling device for plastic packaging box production. BACKGROUND

[0002] Plastic packaging boxes are a common packaging material, commonly used for packaging food, daily necessities, cosmetics and other goods. They are usually made of plastic materials such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). Plastic packaging boxes have the following characteristics and advantages: lightweight, durable, transparent, waterproof and moisture-proof, strong formability, and relatively low cost. After the plastic packaging box is processed and formed, it needs to be cooled.

[0003] In the prior art, the Chinese patent document with application number 202022209906.8 discloses a cooling device for plastic packaging box production, which includes legs, a rack, a conveyor belt, a cooling chamber, a refrigeration unit, a blower, a connecting pipe, a supply air pipe, a manifold, and an air outlet. The rack is fixedly installed on the top of the legs, and the top of the rack is provided with the cooling chamber. The conveyor belt is installed on the inner side of the rack and passes through the cooling chamber. The front of the cooling chamber is fixedly provided with a manifold. This cooling device for plastic packaging box production can accelerate the flow of cold air in the cooling chamber, thereby improving the cooling efficiency of the plastic packaging box. By installing an adsorption pipe filled with activated carbon on the exhaust pipe, the exhaust gas from the exhaust port can be adsorbed and purified, reducing the impact of odor exhaust gas generated during the cooling of the plastic packaging box on the environment and personnel, and improving the workshop environment.

[0004] However, the above technical solution has the following problems: the plastic packaging box is directly cooled by the cooling air after being conveyed by the conveyor belt into the cooling chamber. Since the plastic packaging box is prone to deformation, the rapid thermal expansion and contraction can cause the plastic packaging box to shrink and deform, which cannot guarantee the forming quality of the plastic packaging box. In addition, the position of the blower does not have a filtering structure, which directly draws external air into the cooling chamber, causing dust in the external air to enter the cooling chamber and adhere to the plastic packaging box, which contaminates the plastic packaging box. Therefore, we propose a cooling device for plastic packaging box production to solve the above problems. UTILITY MODEL CONTENTS
