[0002] The fireproof door bears the vital fire safety function in the building, and its fireproof performance and airtightness directly affect the personnel safety and property protection when the fire occurs. In the production process of the fireproof door, the role of the gluing device is particularly significant. The gluing device can enhance the fireproof performance of the fireproof door. By applying glue between the fireproof materials, the bonding force between them can be improved, and a sealed structure is formed, thereby effectively preventing the spread of flames and heat. Secondly, the gluing device improves the airtightness of the fireproof door, which can fill the gap between the door frame and the door leaf, avoid the penetration of smoke and flames, and improve the overall fireproof effect.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] Please refer to Figures 1-5An embodiment of this utility model provides a fire door processing equipment, including a long, rectangular frame 1 and a double-belt transfer assembly 2 installed inside the long, rectangular frame 1 for pulling the fire door workpiece forward in the X-axis direction. The long, rectangular frame 1 has a cavity 3 inside. One end of the surface of the long, rectangular frame 1 is equipped with a double-sided adhesive spraying structure 4 for simultaneously spraying adhesive onto the upper and lower surfaces of the fire door. Both inner walls of the long, rectangular frame 1 are fixed with protruding plates 5. The top of the long, rectangular frame 1 above the protruding plates 5 is fixed with a support leg 6. An adaptive adhesive rolling structure 7 is installed between the two protruding plates 5 and between the two support legs 6 in the same Y-axis direction. A gap is provided between the two adaptive adhesive rolling structures 7 for the fire door workpiece to pass through.

[0019] The dual-belt transfer assembly 2 includes driven pulleys 203 rotatably mounted on the two inner walls of the U-shaped long frame 1, a drive shaft 201 rotatably mounted on one end of the inside of the U-shaped long frame 1, drive pulleys 202 fixed at both ends of the surface of the drive shaft 201, and a conveyor belt 204 fitted on the driven pulleys 203 and the drive pulleys 202. A servo motor 205 for driving the drive shaft 201 to rotate is installed on the outer wall of one side of the U-shaped long frame 1. Tensioning wheels rotate on both inner walls of the U-shaped long frame 1, and the tensioning wheels are in contact with the outer peripheral surface of the conveyor belt 204.

[0020] The fire door with adhesive coating is located on two conveyor belts 204. At this time, the servo motor 205 will drive the two drive pulleys 202 to rotate together through the drive shaft 201. Then the conveyor belt 204 can actively pull the fire door workpiece to move in the X-axis direction, so that it can move stably and smoothly along the preset path.

[0021] The double-sided adhesive spraying structure 4 includes two C-shaped tubes 401 mounted on one end of the surface of the U-shaped long frame 1, a short tube 402 installed between the two C-shaped tubes 401, and several nozzles 404 symmetrically installed on the top and bottom walls of the short tube 402. One of the C-shaped tubes 401 has a liquid inlet main pipe installed on the outer wall of the side away from the servo motor 205, and a solenoid valve 403 is installed at the top of the liquid inlet main pipe.

[0022] The operator opens the solenoid valve 403 and keeps it in the normally open state, so that the adhesive enters one of the C-tubes 401 through the solenoid valve 403. The short tube 402 guides the adhesive into the other C-tube 401. The two C-tubes 401 spray adhesive at the front and rear positions in the direction of movement of the fire door at the same time, while the nozzle 404 sprays adhesive towards the upper or lower surface of the fire door, so as to evenly spray the adhesive onto the workpiece.

[0023] The adaptive glue rolling structure 7 comprises a lower support platform 701 fixed on the outer walls of the two lugs 5, a roller seat 702 hingedly installed on one side of the top end of the lower support platform 701, and a glue rolling roller 703 rotatably installed between the two roller seats 702 in the Y-axis direction. The bottom of the lower support platform 701 is provided with a reset spring 704, the top end of the reset spring 704 is in contact with the lower surface of the roller seat 702, and the lower support platform 701 provides sufficient support area, so that the whole structure can be stably placed on the meandering long frame 1. When the workpiece is conveyed between the two adaptive glue rolling structures 7, it is in contact with the glue rolling roller 703, and the workpiece applies a certain pressure to the glue rolling roller 703, so that the reset spring 704 is deformed, and the reset spring 704 provides the necessary restoring force, so that the glue rolling roller 703 can be closely attached to the surface of the workpiece. Under the rolling action of the glue rolling roller 703, the glue is evenly applied on the surface of the workpiece, and with the movement of the workpiece and the braking of the glue rolling roller 703, the glue is gradually leveled and forms a uniform glue layer.

[0024] In use, the fireproof door workpiece to be glued is first placed by the worker at the starting position of the double-belt conveying assembly 2, which stably supports and conveys the workpiece. Then the worker connects the feeding end of the double-sided glue spraying structure 4 to the conveying end of the external glue, so that the conveying end of the external glue pumps the glue into the double-sided glue spraying structure 4. When the double-belt conveying assembly 2 receives the start signal, the motor in the double-belt conveying assembly 2 starts to work, driving the two conveying belts to move forward at a constant speed. The fireproof door workpiece is driven by the conveying belts to move smoothly along the preset path. During this process, the worker can manually fine-tune the position of the fireproof door workpiece. When the fireproof door workpiece enters the double-sided glue spraying structure 4, the spraying structure is already in standby state and starts to spray glue. The cavity 3 facilitates the double-sided glue spraying of the double-sided glue spraying structure 4, which can simultaneously spray glue on the upper and lower surfaces of the workpiece. With the movement of the fireproof door workpiece, the glue is evenly applied on the upper and lower surfaces of the fireproof door workpiece. During this process, the spraying amount, spraying speed and spraying angle of the spray head in the double-sided glue spraying structure 4 can be adjusted according to the material, size and glue application requirements of the workpiece. After the double-sided glue spraying is completed, the workpiece continues to move forward and enters the adaptive glue rolling structure 7, which can adaptively adjust and actively press the upper surface or the lower surface of the workpiece according to the shape and size of the workpiece. Under the rolling action of the adaptive glue rolling structure 7, the glue on the surface of the fireproof door workpiece is evenly leveled. After the glue application treatment of the adaptive glue rolling structure 7, the glue on the surface of the workpiece starts to solidify. At this time, the solidification process of the glue can be accelerated by heating device or natural air drying.
