Description

Technical Field

[0001] The utility model belongs to the technical field of plastic pallets and relates to a temperature control system for preparing plastic pallets. Background Technique

[0002] A plastic pallet is a logistics unit that is used in conjunction with logistics equipment such as forklifts and shelves. It can be used to store, load, and transport goods and is one of the essential logistics equipment in modern logistics warehousing. The emergence of plastic pallets meets the need for environmental protection, and using plastic pallets instead of wooden pallets is the best product to reduce the damage to forests; it is an inevitable product of the development of the logistics industry. With the continuous strengthening of the concept of food safety and the high requirements for hygiene in the pharmaceutical industry, plastic pallets are favored and sought after by the food and pharmaceutical industries due to their characteristics such as corrosion resistance, moisture resistance, rust resistance, insect resistance, and non-mildewing.

[0003] In the prior art, plastic pallets are mostly produced by injection molding, so injection molding equipment is commonly used in the production of plastic pallets. During the use of the above equipment, the raw materials need to be melted at a high temperature and then injected into the mold, and the plastic pallet is formed through the mold. During the above process, water cooling is required. When using normal-temperature water cooling, the temperature of the water will change with the external environment during the change of seasons, thereby reducing the cooling efficiency. Especially in summer, when using normal-temperature water, the cooling speed is 122 - 126 S / piece.

[0004] To sum up, to solve the deficiencies in the prior art, the utility model relates to a temperature control system for preparing plastic pallets. The temperature control system for preparing plastic pallets not only effectively improves the working efficiency of plastic pallets, so that the cooling speed does not change due to seasonal changes during the pallet preparation process, but also is convenient to operate.
