DETAILED DESCRIPTION

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

[0021] The fire retardant coating spraying device of the utility model is as follows Figures 1 to 4 As shown, it includes a frame 1, on which a plate conveying channel and a feeding conveying mechanism, a spraying mechanism, a drying mechanism and a discharging conveying mechanism are sequentially arranged along the plate conveying channel.

[0022] The plate conveying channel is a channel for conveying plates, which is arranged horizontally so as to convey the plates horizontally. The feed conveying mechanism is used to convey the plates to be sprayed to the spraying mechanism, and the discharge conveying mechanism is used to drive the plates after spraying to move outside the spraying device. The plates are generally metal plates. The feed conveying mechanism and the discharge conveying mechanism of the utility model specifically include an upper transmission roller 11 and a lower transmission roller 12. There is a gap between the upper transmission roller 11 and the lower transmission roller 12, and the upper transmission roller 11 or the lower transmission roller 12 is connected to a transmission motor 13. The upper transmission roller 11 and the lower transmission roller 12 are metal rollers, and both ends of the metal rollers are rotatably mounted on the frame 1. The gap between the upper transmission roller 11 and the lower transmission roller 12 is the plate conveying channel. The size of the plate conveying channel is adapted to the size of the plate. After the plate enters between the upper transmission roller 11 and the lower transmission roller 12, it can be in close contact with the upper transmission roller 11 and the lower transmission roller 12, ensuring that when the upper transmission roller 11 and the lower transmission roller 12 rotate, it can drive the plate to move horizontally. The transmission motor 13 can be connected to the upper transmission roller 11 or the lower transmission roller 12 through a transmission member such as a coupling and a gear.

[0023] The spraying mechanism is used to spray the fire retardant coating onto the plate. In order to improve the efficiency of spraying, the utility model sprays the upper and lower surfaces of the plate at the same time. The specific structure includes an upper crossbeam 2 and a lower crossbeam 3. The upper crossbeam 2 is provided with a plurality of upper nozzles 4 with a spraying direction facing downward, and the lower crossbeam 3 is provided with a plurality of lower nozzles 5 with a spraying direction facing upward. The upper nozzle 4 and the lower nozzle 5 are both connected to a delivery pipe 6, which is connected to a storage container 7, and a delivery pump 8 is provided on the delivery pipe 6. The upper nozzle 4 and the lower nozzle 5 are respectively located above and below the plate delivery channel.

[0024] The upper crossbeam 2 and the lower crossbeam 3 are fixed horizontally on the frame 1, and the length direction of the upper crossbeam 2 and the lower crossbeam 3 is perpendicular to the transmission direction of the plate. A plurality of upper nozzles 4 are evenly installed on the upper crossbeam 2, and a plurality of lower nozzles 5 are evenly installed on the lower crossbeam 3. The spacing between two adjacent upper nozzles 4 and the spacing between two adjacent lower nozzles 5 are determined according to the spraying range of each nozzle, so as to ensure that the total spraying range of the upper nozzles 4 and the lower nozzles 5 covers the width direction of the plate. The storage container 7 is used to store the fire retardant coating, and equipment such as storage boxes, storage barrels, and storage pools can be used. The delivery pump 8 is used to deliver the fire retardant coating in the storage container 7 to each upper nozzle 4 and the lower nozzle 5, and then use the upper nozzle 4 and the lower nozzle 5 to spray the fire retardant coating onto the upper and lower surfaces of the plate. The upper nozzle 4 and the lower nozzle 5 spray at the same time to improve the spraying efficiency.

[0025] The drying mechanism is used to dry the fire retardant coating sprayed on the plate. Specifically, the drying mechanism includes a horizontally arranged upper heating plate 9 and a horizontally arranged lower heating plate 10. The upper heating plate 9 and the lower heating plate 10 are respectively located above and below the plate conveying channel. The upper heating plate 9 and the lower heating plate 10 can be electric heating plates. The ends of the upper heating plate 9 and the lower heating plate 10 are fixed to the frame 1 by insulating materials. The upper heating plate 9 and the lower heating plate 10 generate heat after being powered on, and the fire retardant coating on the upper and lower surfaces of the plate is baked, so that the fire retardant coating is dried quickly, so as to quickly enter the next process.

[0026] In order to prevent the plate from deviating to the left or right during movement, a guide mechanism is provided between the feeding conveying mechanism and the spraying mechanism, and between the spraying mechanism and the drying mechanism. The guide mechanism guides the plate to ensure that the plate moves stably and linearly.

[0027] Specifically, the guide mechanism includes a left guide wheel 14 and a right guide wheel 15, the axial direction of the left guide wheel 14 and the right guide wheel 15 is in the vertical direction, and the left guide wheel 14 and the right guide wheel 15 are rotatably mounted on the frame 1. The left guide wheel 14 and the right guide wheel 15 are cylindrical, and the distance between the left guide wheel 14 and the right guide wheel 15 is the same as the width of the plate, so that the left and right sides of the plate can fit the circumferential outer wall of the left guide wheel 14 and the right guide wheel 15, and the upper surface and the lower surface of the plate will not contact the circumferential outer wall of the left guide wheel 14 and the right guide wheel 15, so the sprayed fire retardant paint will not be wiped off. The left guide wheel 14 and the right guide wheel 15 limit the position of the left and right sides of the plate, which can prevent the plate from shifting left and right. During the movement of the plate, the plate drives the left guide wheel 14 and the right guide wheel 15 to rotate under the action of friction, thereby reducing friction.

[0028] In order to facilitate the adjustment of the spacing between the left guide wheel 14 and the right guide wheel 15, so as to facilitate the positioning and guiding of plates of different widths, the frame 1 of the utility model is provided with a left telescopic mechanism 16 and a right telescopic mechanism 17, the left telescopic mechanism 16 is connected to a left slider 18, the right telescopic mechanism 17 is connected to a right slider 19, the left guide wheel 14 is mounted on the left slider 18, and the right guide wheel 15 is mounted on the right slider 19. The left slider 18 and the right slider 19 are both slidably matched with the frame 1, and the left telescopic mechanism 16 and the right telescopic mechanism 17 can push the left slider 18 and the right slider 19 to slide, thereby driving the left guide wheel 14 and the right guide wheel 15 to move, thereby changing the spacing between the left guide wheel 14 and the right guide wheel 15. The left telescopic mechanism 16 and the right telescopic mechanism 17 both use linear motors, and can also use cylinders and other devices.

[0029] Fire retardant coatings contain volatile harmful gases, which will endanger the health of workers if they enter the air of the workshop. Therefore, the utility model is provided with a gas collecting hood 20 on one side of the spraying mechanism, and the gas collecting hood 20 is connected to an air pipe 21, and the air pipe 21 is connected to a purification mechanism 22, and an air suction fan 23 is provided on the air pipe 21. When spraying, the air suction fan 23 is started, and the air suction fan 23 sucks the gas near the spraying mechanism into the gas collecting hood 20, and transports the gas to the purification mechanism 22 through the air pipe 21, and is emptied after being purified by the purification mechanism. The gas volatilized by the fire retardant coating will also enter the purification mechanism 22 with the air, so that harmful gases can be prevented from gathering in the workshop and the workshop environment can be improved.

[0030] The purification mechanism 22 can adopt various existing tail gas purification equipment, preferably a water scrubber. The water scrubber can remove easily soluble components in the gas and absorb dust in the gas to play a purification role. In addition, according to the specific components of the harmful gas, a reagent can be added to the suction water of the water scrubber, and the reagent reacts with the harmful gas to absorb the harmful gas.

[0031] The specific working process of the utility model is as follows: the plate is horizontally placed in the feeding conveying mechanism, the feeding conveying mechanism drives the plate to move to the spraying mechanism, and the upper nozzle 4 and the lower nozzle 5 of the spraying mechanism spray the fire retardant coating onto the upper and lower surfaces of the plate. When the plate reaches between the upper heating plate 9 and the lower heating plate 10, the upper heating plate 9 and the lower heating plate 10 generate heat to dry the fire retardant coating on the upper and lower surfaces of the plate. Then the plate reaches the discharging conveying mechanism, and the discharging conveying mechanism outputs the sprayed plate to the outside of the equipment.

[0032] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
