Embodiment Construction
[0015] refer to figure 1 , figure 2 , a release film coating production line, including an unwinding unit 1, a corona unit 2, a feeding traction unit 7, a coating unit 3, a heating system 4, a cooling traction unit 5 and a winding unit 6 connected in sequence, heating The system 4 is provided with a rack 41, and a plurality of ovens 42 are installed above the rack 41, and a fan 43 is installed on the oven 42. By placing the fan 43 directly on the top of the oven 42, the distance to the oven opening is shortened, thereby reducing the air duct. At the same time, the heat source is changed from traditional electric heating and oil heating to natural gas heating, which saves energy and reduces costs; unwinding unit 1, corona unit 2, feeding traction unit 7, coating unit 3, cooling traction unit 5 and The winding units 6 are respectively arranged under the frame 41 , and both the unwinding unit 1 and the winding unit 6 are provided with a dust removal device 11 . A release film ...

The invention discloses a coating production line for release films. The coating production line comprises an unrolling unit, a corona unit, a feeding traction unit, a coating unit, a heating system, a cooling traction unit and a rolling unit, wherein the unrolling unit, the corona unit, the feeding traction unit, the coating unit, the heating system, the cooling traction unit and the rolling unit are sequentially connected; the heating system is provided with a machine frame, and a plurality of drying ovens are installed on the machine frame and are provided with fans; the unrolling unit, the corona unit, the feeding traction unit, the coating unit, the cooling traction unit and the rolling unit are arranged below the machine frame, and the unrolling unit and the rolling unit are provided with dust removal devices. According to the coating production line, the film moving length is reduced, the film moving path is simpler, the distance from moving films to the ground is increased, and the surface cleanliness of base material is high; the machine frame is separated from the coating unit, the feeding traction unit and the cooling traction unit through wallboards, and vibration of the machine frame is prevented from causing adverse effect on the units. The coating production line has the advantages that the film moving length is small, the coating accuracy is high, the product quality is high and the practicality is high.
Description
technical field [0001] The invention relates to a coating production line, in particular to a release film coating production line. Background technique [0002] The coating machine is a device used to coat a layer of glue, paint or ink with a specific function on a rolled soft substrate, such as a release film, PP film and other plastic films, and then wind it up after drying. However, the traditional release film coating production line has the following disadvantages: the process film route is complicated, which affects product quality; the frame is connected to the coating wallboard, and the vibration of the fan affects the coating accuracy of the coating head, which reduces the product quality. Quality: The heating part of the coating machine has long air ducts, many bends, large wind resistance and high energy consumption. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a release film coating ...
