[0001] The utility model relates to the technical field of fireproof door processing and production, in particular to a fireproof door panel spraying and drying integrated machine. Background Art

[0002] A fire door is a door that, in addition to having the functions of an ordinary door, also has the function of preventing the spread of fire and smoke volcanoes, which helps to evacuate people safely. During the processing and production of fire doors, the surface of the fire doors needs to be sprayed with fire-retardant paint that has fire-retardant and flame-retardant effects. At the same time, it also protects the fire doors from rust and corrosion. After the fire doors are painted, they need to be dried.

[0003] At present, the painting and drying of fire doors are usually divided into two steps. After the fire doors are painted in the painting equipment, they need to be transferred to the lower drying equipment for drying, which reduces the production and processing efficiency. For this reason, we propose a fire door panel spraying and drying all-in-one machine. Utility Model Content

[0004] The purpose of the utility model is to provide an all-in-one spraying and drying machine for fireproof door panels, which has the advantages of being able to continuously complete the painting and drying of fireproof doors, and the painting and drying are carried out simultaneously, thereby improving the production and processing efficiency, and solving the problem that the painting and drying of fireproof doors are usually divided into two steps at present, and the fireproof doors need to be transferred to the lower drying equipment for drying after the painting is completed in the painting equipment, thereby reducing the production and processing efficiency.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a fireproof door panel spraying and drying machine, comprising a cover shell, a paint liquid pipe and a hot air pipe, wherein a first conveying rack and a second conveying rack are respectively installed inside the cover shell near the lower surface and the upper surface, and conveying chain plates are arranged inside the first conveying rack and the second conveying rack, and a plurality of friction blocks are equidistantly installed on the outer surfaces of the two conveying chain plates, and branch pipes are symmetrically installed on one side of the cover shell near the front surface and the rear surface, and a plurality of nozzles are equidistantly installed on the opposite sides of the two branch pipes, and a drying air hood is installed on the side of the inner wall of the cover shell away from the two branch pipes.

[0006] Preferably, one end of the paint liquid tube is connected to a connecting liquid tube, and both ends of the connecting liquid tube are respectively connected to the outer surfaces of the two branch tubes.

[0007] Preferably, one end of the hot air duct is connected to a connecting air duct, and both ends of the connecting air duct are respectively connected to the outer surfaces of two drying air hoods.

[0008] Preferably, a collecting tank is installed on the lower surface of the cover shell.

[0009] Preferably, a porous flow equalizing plate is installed inside the two drying air hoods.

[0010] Preferably, two partitions are provided inside the casing between the branch pipe and the drying air hood, and the two partitions are symmetrically installed on the inner wall of the casing near the front surface and the rear surface.

[0011] Preferably, brush plates are symmetrically installed on the side of the outer surface of the housing facing away from the drying air hood, near the front surface and the rear surface.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model achieves the effect of continuously completing the painting and drying of the fire door by arranging a cover shell, a first conveyor frame, a second conveyor frame, a conveyor chain plate, a friction block, a branch pipe, a nozzle and a drying hood, and the painting and drying are carried out simultaneously, thereby improving the production and processing efficiency. The top and bottom ends of the fire door are respectively in contact with and clamped by the friction blocks on the two conveyor chain plates, and the two conveyor chain plates rotate synchronously to allow the fire door to enter the inside of the cover shell, and the nozzles on the two branch pipes spray fire retardant paint on the front and rear surfaces of the fire door respectively. When the fire door after painting enters between the two drying hoods, the paint on its surface is dried, and the dried fire door is transported away.

[0014] 2. The utility model achieves the effect of facilitating the adhesion of fire retardant paint to the surface of the fire door by providing a brush plate. Before the fire door enters the interior of the cover, the dust and impurities on the front and rear surfaces of the fire door are brushed off by the brush plate to prevent the dust and impurities from affecting the adhesion of the fire retardant paint to the surface of the fire door.

[0015] 3. The utility model achieves the effect of evenly drying the paint on the surface of the fire door by setting a porous equalizing plate. The porous equalizing plate allows the drying hot air inside the drying hood to be evenly blown out, thereby evenly blowing to the paint on the surface of the fire door, thereby evenly drying the paint on the surface of the fire door.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1-Figure 3 As shown, the utility model proposes a fireproof door panel spraying and drying integrated machine, which includes a cover shell 2, a paint liquid pipe 9 and a hot air pipe 11, and the two sides of the cover shell 2 are connected, and the first conveying frame 3 and the second conveying frame 7 are respectively installed near the lower surface and the upper surface inside the cover shell 2, and the first conveying frame 3 and the second conveying frame 7 pass through the cover shell 2, and the two ends of the first conveying frame 3 and the second conveying frame 7 are respectively located on both sides of the cover shell 2, and conveying chain plates 4 are arranged inside the first conveying frame 3 and the second conveying frame 7, and the two conveying chain plates 4 rotate synchronously, and a plurality of friction blocks 5 are equidistantly installed on the outer surfaces of the two conveying chain plates 4, and the friction blocks 5 on the two conveying chain plates 4 correspond to each other one by one.

[0022] Branch pipes 13 are symmetrically installed on one side of the interior of the cover shell 2 near the front surface and the rear surface, and a number of nozzles 12 are equidistantly installed on the opposite sides of the two branch pipes 13. One end of the paint liquid pipe 9 is connected to the connecting liquid pipe 8, and the two ends of the connecting liquid pipe 8 are respectively connected to the outer surfaces of the two branch pipes 13. The fire-retardant paint enters the branch pipe 13 through the paint liquid pipe 9 and the connecting liquid pipe 8, and the end of the paint liquid pipe 9 is connected to the output end of the spray pump. A collecting tank 1 is installed on the lower surface of the cover shell 2, and the upper part of the collecting tank 1 is open, so the paint liquid dripped during the spraying process falls into the collecting tank 1. A drying air hood 15 is installed on the side of the inner wall of the cover shell 2 away from the two branch pipes 13, and the air outlets of the two drying air hoods 15 are arranged on the opposite side, so that the two drying air hoods 15 can transport dry hot air to the front and back surfaces of the fire door.

[0023] A porous flow equalizing plate 16 is installed inside the two drying hoods 15. The porous flow equalizing plate 16 allows the drying hot air inside the drying hood 15 to be blown out evenly, thereby evenly blowing toward the paint on the surface of the fire door, thereby evenly drying the paint on the surface of the fire door. One end of the hot air duct 11 is connected to a connecting air duct 10, and both ends of the connecting air duct 10 are respectively connected to the outer surfaces of the two drying hoods 15, and the end of the hot air duct 11 is connected to the output end of the hot air blower, and the drying hot air enters the drying hood 15 through the hot air duct 11 and the connecting air duct 10.

[0024] Brush plates 6 are symmetrically installed on the side of the outer surface of the cover 2 away from the drying air hood 15 near the front surface and the rear surface. The fire door passes between the two brush plates 6 before painting. The dust and impurities on the front and rear surfaces of the fire door are brushed off by the brush plates 6 to prevent the dust and impurities from affecting the adhesion of the fire retardant paint on the surface of the fire door. Two partitions 14 are arranged inside the cover 2 between the branch pipe 13 and the drying air hood 15, and the two partitions 14 are symmetrically installed on the inner wall of the cover 2 near the front surface and the rear surface. A gap is set between the two partitions 14 for only the fire door to pass through, so as to reduce the entry of drying hot air into the painting area inside the cover 2.

[0025] When the utility model is in use, the top and bottom ends of the fire door are in contact with the friction blocks 5 on the two conveying chain plates 4 respectively and are clamped, and the two conveying chain plates 4 rotate synchronously to allow the fire door to enter the interior of the cover shell 2, and before the fire door enters the interior of the cover shell 2, the dust and impurities adhering to the front and rear surfaces of the fire door are brushed off by two brush plates 6, and after the fire door enters the interior of the cover shell 2, the nozzles 12 on the two branch pipes 13 spray fire retardant paint on the front and rear surfaces of the fire door respectively, and when the fire door after painting passes between the two partitions 14 and enters between the two drying hoods 15, the paint on its surface is dried, and the dried fire door is transported away.
