Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, in particular to a drying device for coating. Background Art

[0002] Coating technology refers to coating a fluid such as an adhesive on a substrate through a coating device, and drying or curing the coated fluid coating through an oven by a conveying and winding system, so that the substrate is added with a film layer with special functions. This technology is widely used in dozens of industries such as industry, people's livelihood, electronics and optoelectronics, communication, new energy, and construction. Drying is an important step in the coating process, and its purpose is to remove moisture, solvents or other volatile components in the coating coated on the substrate, so that the coating is cured and tightly attached to the substrate. The drying step requires the use of a drying device.

[0003] Common drying devices for coating usually consist of structures such as a drying oven, inlets and outlets, a temperature control system, a heat source, a sewage disposal system, and a conveying system. The conveying system transports the substrate into the drying oven through the inlets and outlets. After the heat source is started and heated up, the temperature is controlled by the temperature control system, so as to dry the substrate, and then the generated waste gas is discharged by the sewage disposal system.

[0004] Traditional drying devices for coating can only perform single-sided drying. When double-sided drying is required, it is necessary to first dry and wind one side, and then dry the other side. This method requires a lot of operations, has complicated steps, is not easy to use, and has low efficiency. To solve the above problems, some drying devices for coating are provided with heating components at the upper and lower parts of the inner cavity of the device. When the substrate moves at the central position of the inner cavity of the device, the two groups of heated heating components can dry both sides of the substrate, and then wind the substrate. However, in this way, since the coating is not dried after coating, the solvent in the coating liquid will remain liquid, making the coating have a certain fluidity. At the same time, after the substrate and the coating move into the interior of the device, the liquid in the coating will drip, and the liquid will drip on the lower heating component. At the same time, since the liquid in the coating contains organic solvents or other chemical substances, it will not only damage the heating component, but also cause equipment failures or alarms, resulting in the stop of the drying step of the coating. For this reason, a drying device for coating is proposed. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a drying device for coating to solve the technical problem that the liquid in the coating drips on the heating component, causing damage, and triggering equipment failures or alarms, resulting in the stop of the drying step.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A drying device for coating, comprising:

Jet plates are additionally provided at the centers of the upper and lower parts of the inner cavity of the device housing, and jet holes are formed on the surfaces of the jet plates.

[0008] A blower, provided at the upper and lower parts of the center on the back of the device housing.

Air guiding plates are horizontally installed directly above the front and rear ends of the liquid receiving plate. After guiding the base material into the inner cavity of the device housing through the feed inlet, the blower sucks in the outside air, heats it up through the motor heat pipe inside the air heating box, then conveys the hot air into the jet plate, and sprays the hot air onto the surface of the base material through the jet holes for drying. The hot air sprayed by the jet plate located at the lower part of the inner cavity of the device housing rises along the front and back surfaces of the liquid receiving plate and moves towards the base material under the guidance of the air guiding plates. When the liquid in the coating on the moving base material drips, it enters the inside of the liquid receiving plate under the action of gravity. On the one hand, the dripping liquid can be collected to avoid damage caused by the liquid dripping on the heating component and prevent equipment failure or alarm, and the phenomenon of stopping the drying step. On the other hand, although the liquid receiving plate for collecting the dripping liquid is directly above the top of the jet plate, it does not affect the drying effect of the hot air on the base material.

[0010] Preferably, rotating rollers are vertically provided at the upper and lower parts of the inner cavities of the feed inlet and the discharge outlet, and the rotating rollers are rotatably connected to the inner wall of the device housing. The base material can touch and move with the rotating rollers to avoid the phenomenon of the base material being worn due to friction with the outside of the feed inlet and the discharge outlet.

[0011] Preferably, screws are threadedly connected to the centers of the front and rear ends of the top and bottom of the device housing, and the bottom ends of the screws are connected to the surface of the jet plate. The screws can be rotated on the device housing to adjust the use height of the jet plate in the inner cavity of the device housing, thereby accelerating the drying effect and speed of the base material.

[0012] Preferably, the liquid receiving plate is designed as a triangle as a whole and is directly above the top of the corresponding jet plate. The four corners of the liquid receiving plate are connected to the inner wall of the device housing. The liquid receiving plate with a triangular design and an inverted setting can make the liquid concentrate at the center position of the top of the liquid receiving plate.

[0013] Preferably, side connecting plates are additionally provided at the lower parts of the center positions on both sides of the device housing, and the side connecting plates are rotatably connected to the inner wall of the device housing. The side connecting plates can be rotated on the device housing to separate the side connecting plates from the device housing, and the liquid on the liquid receiving plate can be cleaned.

[0014] Preferably, positioning blocks are installed at the front and rear ends on the outer side of the side connection plate, and telescopic positioning rods are additionally provided at the front and rear ends directly below the bottom of the side connection plate. The telescopic positioning rods are connected to the device housing and correspond to the positioning blocks. When the side connection plate rotates outward on the device housing to a certain angle, the telescopic ends of the telescopic positioning rods can be pulled out and inserted into the inside of the positioning blocks for connection, ensuring the stability of the side connection plate when cleaning the docking liquid plate.

[0015] Preferably, an arc-shaped spring is vertically provided at the central position on the outer side of the side connection plate, and both ends of the arc-shaped spring are respectively connected between the side connection plate and the device housing. After the docking liquid plate is cleaned, when the telescopic end of the telescopic positioning rod is separated from the positioning block, the side connection plate is reset under the action of the arc-shaped spring and fits tightly with the device housing, thereby ensuring the tightness of the connection between the side connection plate and the device housing, preventing hot air from leaking and affecting the drying effect of the substrate.

[0017] For this drying device for coating, after guiding the substrate into the inner cavity of the device housing through the feeding port, the fan inhales the outside air, heats it up through the motor heat pipe inside the air heating box, then conveys the hot air into the jet plate, and sprays the hot air onto the surface of the substrate through the jet holes for drying. The hot air sprayed by the jet plate located in the lower part of the inner cavity of the device housing rises along the front and back sides of the liquid receiving plate and moves towards the substrate under the guidance of the air guiding plate. Although the liquid receiving plate for collecting the dripping liquid is directly above the top of the jet plate, it does not affect the drying effect of the hot air on the substrate. When the liquid in the coating on the substrate in the moving state drips, it enters the inside of the liquid receiving plate under the action of gravity. The dripping liquid can be collected, preventing the liquid from dripping on the heating component and causing damage, and triggering equipment failure or alarm, resulting in the drying step stopping.
