[0002] Fire extinguisher boxes are specially designed to store and protect fire safety equipment such as fire extinguishers, fire hoses, and fire hydrants. They are typically installed in prominent locations in public places or buildings for quick access in emergencies. During production, fire extinguisher boxes are often painted to improve their corrosion resistance, aesthetics, and brand recognition. Common painting types include powder coating and liquid coating. Painting not only provides a durable protective layer but also increases the product's visual appeal, and different colors can be chosen to meet specific requirements or brand image. The common practice in fire extinguisher box painting is to paint one side at a time, followed by the other. This method is inefficient, has a low yield rate, and requires significant manual labor, which cannot meet the production needs of fire extinguisher boxes. Furthermore, the paint becomes thicker at low temperatures, affecting its flowability and the painting effect. Utility Model Content

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figures 1-8As shown, a multi-angle spraying device for fire box production includes: a spraying box 1, an equipment box 101 installed at the bottom of the spraying box 1, the equipment box 101 and the spraying box 1 being in communication, a workbench 102 set between the equipment box 101 and the spraying box 1, a storage box 103 set outside the spraying box 1, a spraying assembly set inside the spraying box 1, the spraying assembly including: a spraying pipe 2, a horizontal spray head 201, a rotating shaft 202, a rotating hole 203, a transmission gear 204, a uniform speed motor 205 and a drive gear 206, and a mixing assembly set inside the storage box 103, the mixing assembly including: a heating box 3, a heating block 301, a control switch 302, a stirring motor 303, a motor shaft 304 and a stirring rod 305.

[0028] The workbench 102 is equipped with a suction cup 104, a vacuum pump 105 is installed at the bottom of the workbench 102, a vacuum pipe 106 connected to the vacuum pump 105 is installed at the bottom of the suction cup 104, and an exhaust pipe 107 is installed at the outer end of the vacuum pump 105.

[0029] When spraying the fire extinguisher box, place the fire extinguisher box into the spraying box 1 and place it neatly on the workbench 102. At this time, start the air pump 105. The air pump 105 generates negative pressure suction in the air extraction pipe 106 and the suction cup 104, evacuating the air inside the suction cup 104 and then expelling the air from the exhaust pipe 107, so that the inside of the suction cup 104 is in a vacuum state, which can firmly fix the fire extinguisher box on the workbench 102 and prevent the fire extinguisher box from shifting and affecting the spraying quality or falling off.

[0030] The spraying box 1 has a spraying pipe 2 installed on one side inside, and a horizontal spray nozzle 201 installed on the outside of the spraying pipe 2. A rotating shaft 202 is installed at the bottom of the workbench 102. A rotating hole 203 is opened at the bottom inside the equipment box 101. A bearing that is rotatably connected to the rotating shaft 202 is installed inside the rotating hole 203. A transmission gear 204 is installed on the rotating shaft 202. A constant speed motor 205 is installed on one side of the bottom of the equipment box 101. A drive gear 206 is installed on the output shaft of the constant speed motor 205. The drive gear 206 is meshed with the transmission gear 204. A liquid pump 4 is installed on the outside of the storage box 103. A liquid extraction pipe 401 is installed between the liquid pump 4 and the storage box 103. A delivery pipe 402 is installed between the liquid pump 4 and the spraying pipe 2.

[0031] After fixing the fire box onto the workbench 102, start the liquid pump 4 and the constant speed motor 205. The pumping pipe 401 draws out the paint stored in the storage tank 103, which is then pumped into the delivery pipe 402 via the liquid pump 4. From the delivery pipe 402, the paint is discharged into the spray pipe 2. The spray pipe 2 is equipped with a solenoid valve a. Opening the solenoid valve a allows the paint to be delivered to the horizontal spray nozzle 201 and sprayed onto the outer surface of the fire box. Meanwhile, the constant speed motor 205 drives the output shaft, which in turn drives the drive gear 206 to rotate. The drive gear 206 meshes with the transmission gear 204, enabling the drive gear 206 to drive the transmission gear 204 and the rotating shaft 202 to rotate. In turn, the rotating shaft 202 drives the worktable 102 to rotate at a constant speed. During the constant speed rotation, the horizontal spray head 201 can spray different surfaces of the fire box to achieve multi-directional and multi-angle spraying. This solves the problem of low efficiency in the current method of spraying one side and then the other side, improves the coating qualification rate of the fire box, and can meet the coating production needs of the fire box.

[0032] Among them, a diversion pipe 5 is installed on the outside of the spray pipe 2, a solenoid valve 501 is installed on the diversion pipe 5, a vertical spray head 502 is installed at the bottom of the diversion pipe 5, and inclined spray heads 503 are installed on both sides of the bottom of the diversion pipe 5.

[0033] After the exterior of the fire box is coated, the solenoid valve a and the constant speed motor 205 are turned off, and the solenoid valve 501 is turned on so that the paint in the spray pipe 2 can be discharged to the diversion pipe 5. That is, the paint can be delivered to the vertical nozzle 502 and the inclined nozzle 503 for spraying. The vertical nozzle 502 can spray the paint around the center of the fire box for coating, while the inclined nozzle 503 sprays the paint onto both sides of the fire box for coating. This can speed up the coating of the fire box and save coating time.

[0034] The storage bin 103 has a heating box 3 installed on one side inside, a heating block 301 installed inside the heating box 3, a control switch 302 installed at the outer end of the storage bin 103, a stirring motor 303 installed at the top of the storage bin 103, a motor shaft 304 installed at the bottom of the stirring motor 303, the motor shaft 304 passes through the inside of the storage bin 103, and multiple stirring rods 305 are installed on both sides of the outer end of the motor shaft 304.

[0035] When storing paint in storage bin 103, the paint inside may become thick due to low temperatures, resulting in poor flowability. Control switch 302 can activate heating block 301 and stirring motor 303. Once heating block 301 is activated, the temperature inside heating box 3 gradually rises and is conducted to storage bin 103, heating the paint stored in bin 103. This heating reduces the viscosity of the paint, making it easier for the nozzle to atomize and spray evenly onto the fire extinguisher box, ensuring the quality and efficiency of the fire extinguisher box spraying operation. During the paint heating process, stirring motor 303 drives motor shaft 304 to rotate and agitate multiple stirring rods 305, ensuring even heating and good flowability of the paint and preventing nozzle clogging.

[0036] The top of the storage bin 103 is equipped with a feeding port and a sealing cap. When the paint inside the storage bin 103 is used up, the sealing cap can be opened and paint can be added into the storage bin 103 through the feeding port.

[0037] Among them, a vent pipe 108 is installed on one side of the bottom of the vent pipe 106, and a vent valve 109 is installed on the vent pipe 108.

[0038] After the fire box is painted, the ventilation valve 109 is turned on to allow air to enter the ventilation pipe 108, the extraction pipe 106 and the suction cup 104. At this time, the suction cup 104 does not hold the fire box in place, making it easy to remove the fire box from the workbench 102.

[0039] Working principle:

[0040] During the spraying operation of the fire extinguisher box, the fire extinguisher box is placed in the spraying box 1 and placed neatly on the workbench 102 for support. At this time, the air pump 105 is started, which generates negative pressure suction in the air extraction pipe 106 and the suction cup 104, evacuating the air inside the suction cup 104 and then expelling the air from the exhaust pipe 107, so that the inside of the suction cup 104 is in a vacuum state, which can firmly hold the fire extinguisher box on the workbench 102 and prevent the fire extinguisher box from shifting and affecting the spraying quality or falling off. The liquid pump 4 and the constant speed motor 205 are started, so that the liquid extraction pipe 401 extracts the paint stored in the storage tank 103 and discharges it into the delivery pipe 402 through the liquid pump 4. From the delivery pipe 402, it is discharged into the spraying pipe 2, which is equipped with an electromagnetic spraying device. When valve a is opened, solenoid valve a operates, allowing paint to be delivered to the horizontal spray head 201 for spraying. The sprayed paint mist can be applied to the outer surface of the fire box. Meanwhile, the uniform speed motor 205 drives the output shaft to rotate the drive gear 206. Since the drive gear 206 is meshed with the transmission gear 204, the drive gear 206 can drive the transmission gear 204 and the rotating shaft 202 to rotate. In turn, the rotating shaft 202 can drive the worktable 102 to rotate at a uniform speed. During the uniform speed rotation, the horizontal spray head 201 can spray different surfaces of the fire box, achieving the purpose of multi-directional and multi-angle spraying. This solves the problem of low efficiency in the existing method of spraying one side and then spraying the other side, improves the coating qualification rate of the fire box, and can meet the coating production needs of the fire box.

[0041] When storing paint in storage bin 103, the paint inside may become thick due to low temperatures, resulting in poor flowability. Control switch 302 can activate heating block 301 and stirring motor 303. After heating block 301 is activated, the temperature inside heating box 3 gradually rises and is conducted to storage bin 103, heating the paint stored in storage bin 103. This heating reduces the viscosity of the paint, making it easier for the nozzle to atomize and spray evenly onto the fire extinguisher box, ensuring the quality and efficiency of the fire extinguisher box spraying operation. During the paint heating process, stirring motor 303 drives motor shaft 304 to rotate and agitate multiple stirring rods 305, ensuring the paint is evenly heated and has good flowability, preventing nozzle clogging.
