Automatic uniform coating device of fireproof door

Abstract

The invention discloses an automatic uniform coating device of a fireproof door. The automatic uniform coating device of the fireproof door comprises a top plate, a sliding rail, a base plate and tightly-pressing plates. A middle support plate is fixedly welded to the middle position of the lower surface of the top plate. The left end and the right end of the middle support plate are both fixedlyprovided with electric push rods in a welded manner. The end, far away from the middle support plate, of each electric push rod is fixedly provided with an upper end connection sleeve in a welded manner. The lower end of each upper end connection sleeve is connected with a rotatable adjusting rod. According to the automatic uniform coating device of the fireproof door, the fireproof door body is fixed to the tightly-pressing plates on the two sides, the vertical positions of the tightly-pressing plates can be adjusted by rotating the rotatable adjusting rods, the tightly-pressing plates can move left and right in guide sliding grooves under the pushing action of the electric push rods, so that the purposes of adjustment fixing and loosening and conducting fixation according to the specification of the fireproof door body are achieved, and adjustment is convenient; after a coating material is fed in a coating material interval and naturally cooled, a protective film is released, the coating material can adhere to the fireproof door body; and besides, the thickness uniformity of the coating layer is guaranteed, and a good fireproof function is achieved.

Description

technical field [0001] The invention relates to the technical field of an automatic uniform coating device for a fire door, in particular to an automatic uniform coating device for a fire door. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke diffusion. It can prevent the spread of fire and ensure the evacuation of personnel, but it still has the following disadvantages in actual use: [0003] 1. In the actual production process of the fire door, the coating on the surface is often unevenly applied, and there is a phenomenon of over-coating and under-coating, which has a certain impact on i...
