AI Technical Summary
Existing plastic sheet cooling devices suffer from poor cooling effect due to residual water droplets on the plastic sheets when the fan blows air to cool them down, which increases power consumption. Furthermore, the plastic sheets are prone to bending or twisting when stacked.
A cooling device including a water removal component and a cooling component was designed. The water removal component removes water droplets from the surface and bottom of the plastic sheet using a scraper and a drying block. The cooling component cools the plastic sheet by blowing air through upper and lower fans, ensuring that the plastic sheet is dry and has mechanical strength.
It improves the cooling efficiency of plastic sheets, reduces power consumption, and prevents plastic sheets from bending or twisting when stacked, thereby improving production efficiency.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic board cooling, specifically relates to a cooling device for plastic board production. BACKGROUND
[0002] Plastic board is a kind of flat plate product made of plastic as main raw material through extrusion, calendering, injection molding and other processes, which has the characteristics of light weight, corrosion resistance, insulation, easy processing and is widely used in construction, advertising, transportation, home, electronics and other fields. In the production process of plastic board, plastic is melted and shaped at high temperature through extrusion or injection molding process. Once the shaping is completed, it needs to be cooled quickly to solidify the plastic to prevent deformation or shrinkage. The plastic board will pass through the cold water tank on the production line. The cold water is used to take away heat and accelerate the solidification of the plastic board in this process. The cold water can help the plastic board to solidify quickly, thereby improving the production efficiency.
[0003] However, when the existing plastic board is solidified through the cold water tank on the production line, although the cold water can take away the heat on the plastic board, since the plastic board is melted at high temperature and produced by extrusion, only part of the heat can be dissipated, and the plastic board still has heat. If the plastic board is not completely cooled and stacked, the gravity will cause the plastic board to bend or twist, so the plastic board needs to be further cooled and cooled by a cooling device. The existing cooling device generally uses a fan to cool and cool. Since there are still a large number of water droplets on the plastic board when it is removed from the cold water tank, if the water droplets adhere to the plastic board, the fan will produce a large resistance when blowing and cooling, resulting in poor cooling effect of the plastic board and increased power consumption.
