Description

Cooling device for vacuum plastic suction box Technical Field The utility model particularly relates to the technical field of vacuum plastic sucking box cooling, in particular to a vacuum plastic sucking box cooling device. Background The vacuum plastic box needs to be cooled after molding because in the plastic sucking process, the plastic sheet is heated and softened and then molded on a mold through vacuum adsorption; if the plastic box is not cooled, the plastic box can not keep the formed shape due to the flexibility and internal stress of the plastic box, and the cooling process can enable plastic molecules to be converted into a relatively stable state from an active state after being heated, so that the plastic box is solidified, and the designed shape and size precision are maintained; When the vacuum forming is carried out on the existing plastic sucking box, the rapid cooling of the plastic sucking box is required to be realized by adopting a cooling device, the forming cooling of the plastic sucking box is realized when the vacuum forming is carried out, but the traditional air cooling device needs longer cooling time and can not effectively ensure the uniform cooling of products, so that the deformation condition of the products can be caused and the quality of the products can not be effectively ensured, and when the cooling is carried out in a water cooling mode, the products are required to be placed in cooling water, and thus, larger interference can be caused when the products are vacuum formed. Through retrieval, chinese patent publication No. CN202323630166.5 discloses a demolding cooling device for a plastic suction box, which comprises a workbench, wherein an air cylinder is arranged on the workbench, a telescopic rod is arranged on the workbench, a supporting plate for placing a mold is arranged at the telescopic end of the telescopic rod, the supporting plate is connected with a movable rod of the air cylinder, so that the air cylinder can drive the supporting plate to move up and down during operation, a plastic suction groove is formed in the middle of the workbench, a supporting frame is arranged on one side of the workbench, a motor is arranged on the supporting frame, rotating shafts are arranged on two parts of the workbench in a rotating manner, rollers are sleeved on the rotating shafts, the rotation of the two rollers can respectively input and output plastic sheets for manufacturing the plastic suction box to the workbench, and a belt pulley set is jointly arranged on an output shaft of the motor and the rotating shaft on the far side; The product in above-mentioned patent is moving up through cylinder drive backup pad, makes the mould tensile hug closely the plastic sheet, then takes out the air between plastic sheet and mould, and after the shaping of plastic uptake box, starts the thermantidote, realizes the cooling shaping to the plastic uptake box, and simple forced air cooling can not carry out even cooling to the product in the short time, and the in-process of product at the transmission like this can take place the circumstances of deformation, can not effectually guarantee the quality of product, causes production efficiency's reduction.
