Double-faced coating all-in-one machine and coating method thereof

Abstract

The invention discloses a double-faced coating all-in-one machine and a coating method thereof. The technical scheme has the key points that the double-faced coating all-in-one machine comprises a rack, a discharging roll with a base material, a first coating head for coating the front surface of the base material, a second coating head for coating the back surface of the base material, a drying box for drying the base material, a collecting roll for containing the base material, and a plurality of tension control devices for providing tension for the operation of the base material; the discharging roll, the first coating head, the second coating head, the collecting roll and the tension control devices are arranged on the rack; the collecting roll is arranged above the discharging roll; the base material is pulled out from the discharging roll; after the front surface of the base material is coated by the first coating head, the base material penetrates through the drying box and the back surface of the base material is coated by the second coating head; and then the base material returns to penetrate through the drying box and then is finally collected by the collecting roll. The coating method comprises the following steps: discharging, coating the front surface, drying the front surface, coating the back surface, drying the back surface, collecting and the like. The collection and discharging of the coating machine can be operated by one person so that the manual cost is reduced and a coating method is simple and convenient.

Description

【Technical field】 [0001] The invention relates to a double-sided coating integrated machine and a coating method thereof. 【Background technique】 [0002] The disadvantages of the existing diaphragm double-sided coating machine as a whole mainly include: long film running route and large loss; the whole machine is high and occupies a large area; the oven part and unwinding cannot be completely isolated, which leads to damage to the energy saving and environmental protection of the constant temperature workshop ; The distance between receiving and unwinding is far apart, resulting in an increase in the number of operators. The oven part is separated from the ground and it is very inconvenient to open the door to penetrate the film and clean it on the side. 【Content of invention】 [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a double-sided coating integrated machine with a reasonable structure and a coating method ...
