Description

Technical Field

[0001] The present invention belongs to the technical field of fire door production, and particularly relates to an efficient glue spraying device for fire doors. Background Art

[0002] When producing fire doors, multiple processes are required, including the glue spraying process. The traditional glue spraying methods are generally manual glue spraying by workers and machine glue spraying. Manual glue spraying has low efficiency and a large workload, which will bring a heavy work burden to workers. The traditional machine glue spraying generally installs multiple groups of glue guns above the conveyor belt and then sprays glue on the material plates passing through on the conveyor belt. Although this glue spraying method can improve the glue spraying efficiency to a certain extent, it also has great limitations. First, the specifications of the fire doors produced by the factory are not completely the same, and according to different fire prevention requirements, the thicknesses of the fire doors are also different. The traditional machine glue spraying method can only spray glue on material plates with fixed specifications and fixed thicknesses. Once it is necessary to spray glue on material plates with different specifications, it cannot be achieved. Therefore, an efficient glue spraying device for fire doors is proposed. By changing the traditional glue spraying method, the glue spraying efficiency can be increased, and it can be applied to material plates with different specifications and thicknesses, which is convenient and practical.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0021] Please refer to Figures 1-6, the present invention provides the following technical solutions: An efficient glue spraying device for fire doors, including a base 3 and a conveyor belt 20. The base 3 includes a load-bearing plate 301. Four support legs 302 are fixedly connected to the bottom of the load-bearing plate 301. Second chutes 303 are provided on four sides of each support leg 302. Second sliders 305 are arranged in the four second chutes 303 and are matched with them. Lift sleeves 304 are fixedly connected to the outside of the four second sliders 305. Four support frames 306 are fixedly connected to the bottom of the lift sleeves 304. A lift plate 307 is fixedly connected between the four lift sleeves 304. A hydraulic rod 308 is fixedly connected to the bottom of the load-bearing plate 301. The driving end of the hydraulic rod 308 is fixedly connected to the center of the top of the lift plate 307. When the hydraulic rod 308 works, it drives the lift plate 307 to move up and down. The lift plate 307 drives the four lift sleeves 304 to move up and down. The lift sleeves 304 drive the support frames 306 to move up and down. When the support legs 302 support the ground, the height of the base 3 is the lowest. When the support frames 306 support the ground, the height of the base 3 becomes higher. When the lift sleeves 304 move up and down, they will drive the second sliders 305 to move up and down in the second chutes 303, so that the lift plate 307 remains stable when moving up and down. The base 3 passes through below the conveyor belt 20. A first support plate 21 and a second support plate 19 are fixedly connected to the top of the base 3. A control switch 34, a PLC controller 2, and a fixing plate 8 are fixedly connected to the left side surface of the first support plate 21. The control switch 34 is externally connected to a power source, and the control switch 34 and the PLC controller 2 are electrically connected by a wire. The control switch 34 and the hydraulic rod 308 are electrically connected by a wire. The control switch 34 and the conveyor belt 20 are electrically connected by a wire. The working states of the PLC controller 2, the hydraulic rod 308, and the conveyor belt 20 can be controlled through the control switch 34. A motor 7 is fixedly connected to the top of the fixing plate 8. The motor 7 is a servo motor 7. The PLC controller 2 and the motor 7 are electrically connected by a wire. The rotation direction and speed of the motor 7 can be controlled through the PLC controller 2. First mounting plates 9 are fixedly connected to the tops of the first support plate 21 and the second support plate 19. A screw rod 18 is rotatably connected between the two first mounting plates 9. The output shaft of the motor 7 and one end of the screw rod 18 are fixedly connected. A sliding rod 17 is fixedly connected between the two first mounting plates 9. A sliding sleeve 12 matched with it is sleeved on the sliding rod 17. A threaded sleeve 11 is threadedly connected to the screw rod 18. The bottom of the threaded sleeve 11 and the sliding sleeve 12 are fixedly connected to a moving plate 15. A glue gun 24 is fixedly connected to the bottom of the moving plate 15. When the motor 7 works, it drives the screw rod 18 to rotate synchronously. Under the action of the thread, the threaded sleeve 11 moves left and right on the screw rod 18, and at the same time drives the moving plate 15 to move synchronously. The moving plate 15 drives the glue gun 24 to move synchronously.Thus, the glue gun 24 runs in a V-shaped route on the material plate to achieve the purpose of glue application. A feed joint 16 is arranged on the side of the glue gun 24. The feed joint 16 is externally connected to a glue bucket through a hose. On both sides of the top of the moving plate 15, an induction sheet 22 and a connecting rod 14 are respectively fixedly connected. A sixth inductor 25 is fixedly connected to the left side surface of the moving plate 15. Induction points 26 are arranged on the induction sheet 22. A spray head 13 is arranged on the connecting rod 14. The spray head 13 is externally connected to a water injection hose. During operation, the PLC controller 2 and the spray head 13 are electrically connected through a wire. The PLC controller 2 can control the opening and closing of the spray head 13. After the sixth inductor 25 senses the material plate, it automatically feeds back to the PLC controller 2. After receiving the signal, the PLC controller 2 automatically controls the spray head 13 to spray water. Two emergency stop rods 23 are fixedly connected to the back of the moving plate 15. Second mounting plates 5 are fixedly connected to the tops of the first support plate 21 and the second support plate 19. A fixing frame 31 is fixedly connected between the two second mounting plates 5. Two emergency stop switches 30 are fixedly connected to the front of the fixing frame 31. When the moving plate 15 moves, it drives the two emergency stop rods 23 to move left and right. When the emergency stop rod 23 toggles to the emergency stop switch 30, the PLC controller 2 controls the motor 7, the glue gun 24, and the spray head 13 to stop working simultaneously to avoid wasting resources. A first inductor 6 is fixedly connected to the front of the fixing frame 31. A first sliding groove 27 is formed in the front of the fixing frame 31. A first slider 27 matching with the first sliding groove 27 is arranged in the first sliding groove 27. A second inductor 29 is fixedly connected to the front of the first slider 27. The first inductor 6 and the second inductor 29 are located between the two emergency stop switches 30. The first inductor 6 and the second inductor 29 are exactly the same, and the first inductor 6 and the second inductor 29 can only sense the induction points 26. An activity groove 33 communicating with the first sliding groove 27 is formed in the top of the fixing frame 31. An activity rod 32 matching with the activity groove 33 is arranged in the activity groove 33. The bottom end of the activity rod 32 is fixedly connected to the top of the first slider 27. The first slider 27 can be driven to move left and right in the first sliding groove 27 through the activity rod 32, thereby driving the second inductor 29 to move left and right, achieving the purpose of adjusting the distance between the first inductor 6 and the second inductor 29, and thus adjusting the working route of the glue gun 24 to adapt to material plates of different specifications, so as to carry out non-standardized production. A third inductor 1, a fourth inductor 4, and a fifth inductor 10 are fixedly connected to the top of the first support plate 21. The third inductor 1 and the fourth inductor 4 are located behind the second mounting plate 5. The fifth inductor 10 is located in front of the first mounting plate 9. The third inductor 1, the fourth inductor 4, and the fifth inductor 10 are exactly the same. The PLC controller 2 is electrically connected to the first inductor 6, the second inductor 29, the third inductor 1, the fourth inductor 4, the fifth inductor 10, and the sixth inductor 25 through signal lines.,

[0022] Working principle and usage process of the present invention: When in use, first, turn on the PLC controller 2 by controlling the switch 34. Then, adjust the position of the second sensor 29 according to the specification of the material plate. The first slider 27 can be driven by the movable rod 32 to move left and right in the first chute 27 to adjust the second sensor 29 to a suitable position. Then, start the hydraulic rod 308 by controlling the switch 34 to adjust the adjusting base 3 to a suitable height so that the glue gun 24 and the material plate maintain an appropriate distance. Then, place the material plate flat on the conveyor belt 20. After the third sensor 1 detects the material plate, it automatically feeds back to the PLC controller 2, and the PLC controller starts timing. After the fourth sensor 4 detects the material plate, it automatically feeds back to the PLC controller 2. The PLC controller 2 automatically calculates the length of the material plate and the rotation speed of the conveyor belt 20 based on the time when the material plate reaches the third sensor 1 and the fourth sensor 4, and calculates the time when the material plate reaches below the glue gun 24 and the number of reciprocating operations of the glue gun 24. At the same time, the PLC controller 2 also calculates the number of reciprocating water spraying operations of the spray head 13. When the material plate reaches below the glue gun 24, the PLC controller 2 controls the motor 7 to drive the screw rod 18 to rotate forward. Under the action of the thread, the thread sleeve 11 drives the moving plate 15 to move to the right. As the moving plate 15 moves to the right, the PLC controller 2 controls the glue gun 24 to start pouring glue at the same time. When the second sensor 29 senses the sensing point 26, the PLC controller 2 controls the motor 7 to rotate in the reverse direction. When the first sensor 6 senses the sensing point 26, the motor 7 rotates forward again, so that conveying and pouring glue are carried out simultaneously, and the glue gun 24 runs on the material plate in a V-shaped route. After the sixth sensor 25 detects the material plate, it automatically feeds back to the PLC controller 2. After receiving the signal, the PLC controller 2 automatically controls the spray head 13 to spray water. The running route of the spray head 13 is the same as that of the glue gun 24. The first sensor 6 and the second sensor 29 will record the number of times the moving plate 15 drives the glue gun 24 to move back and forth and synchronously transmit it to the PLC controller 2. Until the number of operations of the glue gun 24 reaches the number calculated by the PLC controller 2, the PLC controller 2 controls the glue gun 24 to stop pouring glue. At this time, the PLC controller 2 controls the motor 7 to continue working. When the number of operations of the spray head 13 reaches the number calculated by the PLC controller 2, the PLC controller 2 controls the spray head 13 to stop working, and at the same time controls the motor 7 to drive the glue 24 and the spray head 13 to reset. And when the motor 7 is working, if the first sensor 6 and the second sensor 29 fail and the motor 7 does not adjust the steering in time according to the instruction, resulting in the moving plate 15 driving the glue gun 24 to move continuously in a certain direction to the left or right, the emergency stop rod 23 on the moving plate 15 will toggle the emergency stop switch 30 in the same direction, so that the PLC controller 2 controls the motor 7, the glue gun 24 and the spray head 13 to stop working, thus avoiding device damage and resource waste. In the present invention, by driving the screw rod 18 to rotate, the thread sleeve 11 drives the moving plate 15 to move left and right, so that the moving 15 plate drives the glue gun 24 to move and work, and cooperates with the conveyor belt 20 to work at the same time, so that conveying and pouring glue are carried out simultaneously.The glue gun 24 is made to run along a V-shaped path on the material plate, thereby accelerating the glue application efficiency. By setting the movable second inductor 29 and the base 3, it is convenient to adjust the glue application range of the glue gun 24 and the height of the glue gun 24 from the material plate, avoiding scratching the glue gun 24 due to the excessive thickness of the material plate. While ensuring the glue application efficiency, the device can be used for non-standardized production without being restricted by the size of the sheet material, and has higher practicability.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
