Description

Technical Field

[0001] The utility model relates to the technical field of color-coated plate production, in particular to a drying device for color-coated plates. Background Art

[0002] Color-coated plates are a kind of building materials that are widely used at present. During the production process of color-coated plates, paint needs to be applied to their surfaces, and after painting, the color-coated plates need to be dried by a drying device. The current production process in the workshop is as follows: The color-coated plate is first painted on one side, then conveyed to the drying device for single-sided drying. After the drying treatment, the other side of the color-coated plate is painted, and then dried again.

[0003] The existing processing method can only dry one side, and it is impossible to dry both sides simultaneously. The reason why it is impossible to dry both sides simultaneously is that if both sides are painted, when the color-coated plate enters the drying device, the edge position of the lower surface of the color-coated plate will surely contact the supporting roller at the entrance of the drying device, causing the roller to rub off the paint at the contact position, thus affecting the product quality of the color-coated plate.

[0004] Based on the above technical problems, in order to improve production efficiency and achieve simultaneous drying of both sides, the inventor has carried out technical transformation on the structure of the drying device, and proposed a drying device for color-coated plates that can dry both sides simultaneously. Summary of the Utility Model

[0005] The utility model aims at the deficiencies of the prior art and provides a drying device for color-coated plates.

[0006] The utility model is realized through the following technical solutions: A drying device for color-coated plates is provided, which includes a workbench. Two side plates are vertically and fixedly connected to the workbench. An upper heating box and a lower heating box are arranged between the two side plates. The color-coated plate after being painted on both sides passes through between the upper heating box and the lower heating box and completes the drying treatment. The position of the lower heating box is fixed, and the height of the upper heating box can be adjusted. The upper heating box, the lower heating box and the two side plates enclose a conveying channel. A supplementary paint roller for supporting the color-coated plate is arranged at the entrance of the conveying channel, and a conveying roller for supporting the color-coated plate is arranged at the exit of the conveying channel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific implementation manners.

[0021] As Figure 1 , 2 shown, the utility model includes a workbench 1. Two side plates 16 are vertically and fixedly connected to the workbench 1. An upper heating box 7 and a lower heating box 2 are arranged between the two side plates 16. The color-coated plate after double-sided painting passes through between the upper heating box 7 and the lower heating box 2 and completes the drying process. The position of the lower heating box 2 is fixed, and the upper heating box 7 can be adjusted in height. The upper heating box 7, the lower heating box 2 and the two side plates 16 enclose a conveying channel. A paint replenishing roller for supporting the color-coated plate is arranged at the entrance of the conveying channel, and a conveying roller for supporting the color-coated plate is arranged at the exit of the conveying channel.
