Technical Field

The invention belongs to the technical field of air floatation drying boxes, and particularly relates to an air floatation drying box with low energy consumption.

Background

At present, the double-sided release paper is solvent-free silicone oil, and can be directly coated and used without adding any solvent when in use, thereby saving the use amount of the solvent and protecting the production environment. And compared with solvent-type organic silicon release agent, the solvent-free silicone oil is suitable for release paper products with light release force and ultra-light release force. The structure of the solvent-free silicone oil double-sided release paper is as follows from top to bottom in sequence: 1 a first release agent layer, 2 a first laminated layer, 3 a raw paper layer, 4 a second laminated layer and 5 a second release agent layer.

The first release agent layer is solvent-free silicone oil, and the coating thickness is as follows: 0.3-1.5 μm;

thickness of first laminated film: 15-20 μm, preferably PE plastic particles;

the raw paper layer is made of white paper and glassine paper;

the thickness of the coating film of the second coating film layer is 15-20 mu m, and PE plastic particles are preferred;

the second release agent layer is solvent-free silicone oil, and the coating ration is that: 0.3-1.5 μm.

The traditional double-sided release paper coating process generally adopts a two-time coating mode, and the coating mode has the following problems

1. When the first surface is coated and then the second surface is coated, silicon is polluted to the other surface to generate adhesion;

2. the production efficiency is low, and the second surface coating speed is low;

3. the substrate is easily scratched.

In order to overcome the technical problems, the solvent-free silicone oil for the double-sided release paper adopts a double-sided simultaneous coating process, and is matched with a suspension type drying mode, and the double-sided simultaneous coating is beneficial to reducing the scratch of the silicon surface, improving the production efficiency and saving the energy consumption, and the double-sided release paper coating process has the following specific characteristics:

1. the double-sided simultaneous coating solves the problems of adhesion of the base material and silicon pollution, improves the production efficiency 2, and the suspension type coating process is in a suspension state after the base material enters the oven, so that the base material is suspended by using upper and lower hot air, the drying efficiency is high, and the problem of scratching the base material is also solved.

The substrate is released by the unreeling mechanism, silicone oil is coated on the upper surface and the lower surface of the substrate simultaneously through the coating mechanism, then the substrate is flatly fed into the suspension oven for drying, an upper nozzle and a lower nozzle are arranged in the suspension oven, the two surfaces of the substrate are dried simultaneously, and the substrate is always in a suspension state in the drying process; and (5) cooling the base material dried by the oven in a cooling mechanism, and finally rolling.

The material is dried simultaneously by the upper and lower array type air nozzles in the drying oven, the double-sided drying efficiency is higher, when the drying oven is used, the two ends of the material are tensioned by the tension provided by the preposed equipment and the postposition equipment, and the material transmitted in the drying oven is kept stable by the air thrust provided by the nozzles above and below the material, so that the material suspension is not interfered with the nozzles below along with the gravity.

The existing air-float drying boxes are all tunnel type ovens, so that the contact time and the contact area of the air-float drying boxes with materials are improved, the length of each oven is long, the materials cannot be effectively stretched when the tension provided by the front and rear equipment of the box body is relatively too small, the problem that the stability of the materials in the ovens is insufficient is easily caused, the problems that the materials interfere with the nozzles below and the materials are twisted are likely to occur, the problems that the nozzles are blocked and the coating layers of the materials are damaged are caused, and even the material clamping condition is caused, so that the working efficiency is affected.

Meanwhile, as the length of the drying box is large, hot gas needs to pass through a flow distribution main pipe with a long length, heat dissipation is easy to occur, and even if the drying box is wrapped by heat insulation materials, the heat dissipation problem still occurs, so that the energy consumption is influenced.
