Description

Technical Field

[0001] The present application relates to the technical field of pre-coating equipment, and in particular to a cooling device for a pre-coating machine. Background Art

[0002] Pre-coated film laminating machine is a commonly used laminating equipment. The production process is similar to that of the pre-coated film. The colloid is dissolved in an organic solvent, and the colloid is rolled on the base film with a concave anilox roller, and then cooled by a cooling roller.

[0003] Most of the existing pre-coating machine cooling devices adopt a single cooling method, which has a poor cooling effect. In addition, when the cooling roller cools the high-temperature film, water droplets may be generated on the cooling roller during the cooling process. The traditional method is to wipe them manually, which is time-consuming and labor-intensive. Some of them clean the water droplets on the cooling roller by installing a cleaning mechanism. The cleaning mechanism generally uses a material that is easy to absorb water. However, when too much water is absorbed, the cleaning effect of the cleaning mechanism on the water droplets on the cooling roller will deteriorate, affecting the quality of the film.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0012] Preferably, the cooling box further comprises a partition plate, which is located in the box body and divides the box body into a cooling chamber and a dewatering chamber, and the cold air pipe and the negative pressure suction pipe are respectively arranged in the cooling chamber and the dewatering chamber.
