Description

A sheet metal spraying device Technical Field

[0001] This utility model relates to the field of fire door processing technology, specifically to a sheet metal spraying device. Background Technology

[0002] Fire doors are a type of door that provides separation and protection. They prevent the spread of fire and smoke, stopping the fire from spreading for a certain period and ensuring the evacuation of personnel. Fire doors can be classified by material as: wooden fire doors, steel fire doors, steel-wood fire doors, and fire doors made of other materials.

[0003] Chinese Patent No. CN220590416U discloses an automatic spraying device for steel fire doors, including a spraying box with a conveying port at the top center. A conveying guide rail is installed at the conveying port. Two sets of gears B are fixedly installed on one side wall of the conveying port, with gears B protruding from the side of the conveying port. Several hook assemblies are installed at the bottom of the conveying guide rail. Gears B can mesh with gears A in the hook assemblies. When the hook assemblies continuously convey to one side through the gears A and B, when gear A on the hook assembly contacts gear B at the conveying port, it will drive the base connected by a plane bearing to rotate, causing the door body to rotate 90 degrees. This allows the subsequent spray pipe A to spray the side of the door body or door frame. The structure is simple and practical, and can achieve side spraying after the door body or door frame is rotated, making the overall spraying of the fire door more uniform.

[0004] However, in the above technical solution, the fire door is only hooked by the hook assembly, and the door is rotated 90 degrees by turning to spray the side. However, when spraying wooden fire doors, it is necessary to spray the front, back and all four sides. The hook assembly will cause obstruction when the spraying equipment sprays from above. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a sheet metal spraying device.

[0006] The technical solution of this utility model is as follows: A panel spraying device includes a spraying box connected to a suspended conveyor, on which multiple suspended trolleys are mounted; a spraying assembly connected to the spraying assembly; in use, two front and rear spraying ends spray the front, back, and sides of the fire door panel; and a connecting assembly connected to the suspended conveyor; the connecting assembly includes a steering assembly and a stabilizing assembly, the steering assembly being connected to the suspended trolleys and including a moving base, a support shaft, and a toothed gear. The rack and pinion are connected to the support shaft, which is mounted on the suspended trolley.

The stabilization component includes a limit rod and a limit block. The symmetrically arranged limit rods are rotatably connected to the moving seat, and the other end of the limit rod is connected to the limit block. When the connecting component is in use, the fire door panel carried under the moving seat moves with the suspended trolley. The toothed gear meshes with the rack, causing the fire door panel to rotate. The limit rods and limit blocks limit the swaying of the fire door panel during movement.

[0008] Preferably, the steering assembly further includes a connecting seat, which is arranged parallel to the suspension trolley and connected to the suspension trolley. The lower end face of the connecting seat is rotatably connected to the support shaft. A hook is connected to the lower end face of the moving seat and is connected to the pre-reserved lifting ring of the fire door panel. A limiting assembly is connected to the support shaft. When the limiting assembly is in use, the limiting assembly restricts the rotation of the support shaft after it moves away from the rack, keeping it at a predetermined angle.

[0009] Preferably, the limiting component includes a fixing ring sleeved on the outside of the support shaft, the support shaft being connected to the connecting seat, and multiple slots being provided on the support shaft; multiple multi-stage telescopic rods being distributed, the multi-stage telescopic rods being connected to the movable seat, and locking blocks being connected to the multi-stage telescopic rods, the locking blocks cooperating with the slots; and elastic elements corresponding in number to the telescopic rods, the elastic elements being sleeved on the outside of the multi-stage telescopic rods.

[0011] Preferably, the stabilization component also includes two stop blocks arranged symmetrically, which are connected to the suspended conveyor and are slidably connected to the limit rod; two support blocks arranged symmetrically, which are connected to the connecting seat; and a positioning component connected to the movable seat. When the positioning component is in use, it restricts the rotated limit rod to keep it in a predetermined position to avoid interference with the spray pipe.

[0012] Preferably, the positioning component includes two magnetic suction components arranged in parallel, which are connected to the connecting seat; and magnetic attachments, the number of which corresponds to the number of magnetic suction components, which are connected to the limiting rod.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, the meshing of the toothed gear and rack in the steering assembly drives the support shaft and the moving seat to rotate, thereby causing the fire door panel to be sprayed to rotate. After passing the upstream spraying end of the spraying assembly to spray the front and back sides, it rotates in time to enter the downstream spraying end. The stabilizing component can keep the fire door panel stable as a whole when rotating, and rotates to avoid the spraying end before entering the spraying end to prevent it from affecting the normal spraying.

[0022] Example 1

[0023] As shown in Figures 1-6, the present invention proposes a panel spraying device, comprising a spraying box 1, a suspended conveyor 2, a suspended trolley 3, a spraying assembly, and a connecting assembly. The spraying box 1 is connected to the suspended conveyor 2, and multiple suspended trolleys 3 are mounted on the suspended conveyor 2. The spraying assembly is connected to the spraying assembly. In operation, the two front and rear spraying ends of the spraying assembly spray the front, back, and sides of the fire door panel.

The toothed gear 6 is connected to the support shaft 5, and the rack 7 is connected to the suspended conveyor 2 and meshes with the toothed gear 6. The stabilization component includes a limit rod 8 and a limit block 9. The symmetrically arranged limit rods 8 are rotatably connected to the moving seat 4, and the other end of the limit rods 8 is connected to the limit block 9. When the connecting component is in use, the fire door panel carried under the moving seat 4 moves with the suspended trolley 3. The toothed gear 6 meshes with the rack 7 to drive the fire door panel to rotate, and the limit rods 8 and limit blocks 9 limit the swaying of the fire door panel during movement.

[0024] Example 2

[0025] As shown in Figures 1 and 2, the present invention proposes a sheet metal spraying device. Compared with Embodiment 1, this embodiment describes the detailed structure of the spraying assembly. The spraying assembly includes a storage tank 10, a spraying frame 11, a spraying pipe 12, and a connecting pipe 13. Two storage tanks 10 are arranged in parallel, and each storage tank 10 is connected to a diaphragm pump. Multiple spraying frames 11 are provided, and the spraying frames 11 are connected to the ground. The spraying pipes 12 are connected to the spraying frames 11, and the spraying pipes 12 on the two spraying frames 11 have different shapes. Multiple spraying heads are connected to each spraying pipe 12. The number of connecting pipes 13 corresponds to the number of spraying frames 11, and the two ends of the connecting pipes 13 are connected to the diaphragm pump and the spraying pipe 12, respectively.

[0026] Example 3

[0027] As shown in Figures 2-6, the sheet metal spraying device proposed in this utility model, compared with Embodiment 2, describes the detailed structure of the connecting component. The steering component also includes a connecting seat 14, a hook 15, and a limiting component. The connecting seat 14 is arranged parallel to the suspension trolley 3 and is connected to the suspension trolley 3. The lower end face of the connecting seat 14 is rotatably connected to the bearing of the support shaft 5. The hook 15 is connected to the lower end face of the moving seat 4 and is connected to the reserved lifting ring of the fire door sheet metal. The limiting component is connected to the support shaft 5. In the use state, the limiting component restricts the rotation of the support shaft 5 after it moves away from the rack 7, keeping it at a predetermined angle.

[0028] In an optional embodiment, the hook 15 consists of a fixed rod 21 and a U-shaped plate 22. One end of the fixed rod 21 is connected to the movable seat 4, and the U-shaped plate 22 is connected to the other end of the fixed rod 21. The U-shaped plate 22 has a groove that matches the pre-reserved lifting ring of the fire door material. The fit between the U-shaped plate 22 and the lifting ring can reduce the shaking that occurs during transportation.

[0029] The limiting assembly includes a fixing ring 16, a telescopic rod 18, an elastic element 19, and a locking block 20. The fixing ring 16 is sleeved on the outside of the support shaft 5. The support shaft 5 is connected to the connecting seat 14. Multiple locking slots 17 are provided on the support shaft 5.

[0030] Multiple multi-stage telescopic rods 18 are distributed around the circumference. The multi-stage telescopic rods 18 are connected to the movable seat 4. The multi-stage telescopic rods 18 are connected to the locking blocks 20, which cooperate with the locking slots 17. The number of elastic elements 19 corresponds to the number of multi-stage telescopic rods 18. The elastic elements 19 are sleeved on the outside of the multi-stage telescopic rods 18. The elastic elements 19 are selected from, but are not limited to, springs.

[0031] The stabilization assembly also includes a stop block 23, a support block 24, and a positioning component. Two stop blocks 23 are symmetrically arranged and connected to the suspended conveyor 2. The stop blocks 23 are also slidably connected to the limit rod 8. The stop blocks 23 are U-shaped. Two support blocks 24 are symmetrically arranged and connected to the connecting seat 14. The support blocks 24 restrict the rotation direction of the limit rod 8, allowing it to rotate only in one direction. The positioning component is connected to the movable seat 4. In use, the positioning component restricts the rotated limit rod 8, keeping it in a predetermined position to avoid interference with the spray pipe 12.

[0032] The positioning assembly includes a magnetic suction element 25 and a magnetic attachment 26. Two magnetic suction elements 25 are arranged in parallel and are connected to the connecting seat 14. The magnetic suction element 25 is selected from, but is not limited to, permanent magnets. The number of magnetic attachments 26 corresponds to the number of magnetic suction elements 25, and the magnetic attachments 26 are connected to the limiting rod 8. The magnetic attachments 26 are selected from metal plates containing iron, cobalt and nickel elements.

[0033] In summary, when using this utility model, the worker restricts the position of the fire door panel by contacting the threaded lifting ring and hook 15 connected in the reserved hole on the fire door panel, and rotates the limiting rod 8 so that the limiting block 9 contacts both ends of the top of the fire door panel to prevent the fire door panel from tilting and shaking. After hoisting is completed, the suspended trolley 3 will travel on the suspended conveyor 2 to carry the fire door panel into the spray box 1. At this time, the spray head on the spray pipe 12 on the upstream spray frame 11 sprays the front and back sides of the fire door panel. During the spraying process, the suspended trolley 3 continues to move forward at a certain speed. During the movement, the front and back sides of the panel are gradually sprayed. Then, the toothed gear 6 on the support shaft 5 gradually contacts the rack 7 connected to the suspended conveyor 2. The toothed gear 6 meshes with the rack 7 and drives itself to drive the support shaft 5 and the moving seat 4. As the fire door panel rotates, the side wall of the fire door panel moves closer to the side wall of the spray box 1. At the same time, the telescopic rod 18 rotates synchronously, causing the locking block 20 to slide on the fixed ring 16. When the locking block 20 contacts the slot 17 on the fixed ring 16, the elastic element 19 rebounds and pushes the locking block 20 into the slot 17 to restrict the continued movement of the support shaft 5, preventing it from moving too far due to inertia and affecting the subsequent side spraying. At the same time as the locking is completed, the two limit rods 8 will contact the stop block 23. The stop block 23 pushes the limit rod 8 to rotate around its own hinge point, so that the limit block 9 moves away from the fire door panel, reducing the obstruction with the fire door panel and preventing the spraying from being incomplete and affecting the fire resistance performance of the wooden fire door. As the suspended trolley 3 continues to move, the two U-shaped spray racks 11 are sprayed near the side of the panel through the spray nozzles on the spray pipe 12, and then gradually moved out of the spray box 1 for centralized drying.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
