Technical Field

[0001] This utility model relates to the field of fire protection equipment manufacturing and processing technology, and in particular to a spray coating machine for the inside of a water-based fire extinguisher bottle. Background Technology

[0002] Water-based fire extinguishers are a commonly used physical fire extinguisher, suitable for extinguishing initial fires of flammable solids or liquids. They are widely used in oil fields, oil depots, ships, factories, shops, and other places, and are essential fire-fighting equipment for preventing fires and protecting people's lives and property.

[0003] Since fire extinguisher cylinders are typically made of steel, and the extinguishing agents in water-based fire extinguishers are corrosive, an anti-corrosion coating is usually applied to the inside of the cylinder before filling to extend its service life. Resin is a common anti-corrosion material for fire extinguishers, offering excellent protection. However, resin has poor adhesion and is difficult to apply evenly to the inside of the cylinder. Therefore, there is a need for an internal spraying device that can achieve a more uniform coating thickness inside the fire extinguisher cylinder. Utility Model Content

[0004] The purpose of this invention is to provide a water-based fire extinguisher bottle internal spraying machine, which aims to solve the problem of uneven spraying thickness in existing internal spraying devices.

[0005] To achieve the above objectives, this utility model provides a water-based fire extinguisher bottle internal spraying machine, including a frame, on which a spraying component and a conveying component are arranged. The spraying component is arranged above the frame and is used to spray the inside of the fire extinguisher bottle; the conveying component is arranged below the frame and is used to convey the fire extinguisher bottle to the area below the spraying component.

[0006] The spraying assembly includes a slider reduction motor, a lifting slider, spray guns, a paint recovery chamber, and a bottle mouth positioning ring.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0026] like Figures 1 to 3 As shown, this utility model provides a water-based fire extinguisher bottle internal spraying machine, including a frame 1, a spraying component 3 and a conveying component 2 arranged on the frame 1. The spraying component 3 is arranged above the frame 1 and is used to spray the inside of the fire extinguisher bottle; the conveying component 2 is arranged below the frame 1 and is used to convey the fire extinguisher bottle to the area below the spraying component 3.

[0027] The spraying assembly 3 includes a slider reduction motor 30, a lifting slider 32, a spray gun 33, a paint recovery chamber 34, and a bottle mouth positioning ring 36. A lifting guide rail 31 is provided on the frame 1, and a slider reduction motor 30 is installed on the lifting guide rail 31. The slider reduction motor 30 is used to drive the lifting slider 32 to slide on the lifting guide rail 31. Multiple spray guns 33 are installed on the lifting slider 32. The paint recovery chamber 34 is installed on the frame 1, and a bottle mouth positioning ring 36 is provided at the bottom of the paint recovery chamber 34. The central axis of the bottle mouth positioning ring 36 coincides with the central axis of the spray gun 33.

[0028] The frame 1 is equipped with a spraying position, which is located directly below the spray gun 33. The spraying position is equipped with a rotary reduction motor 5, and a tray 52 is mounted on the rotary reduction motor 5. The frame 1 is also equipped with a lifting cylinder 50, which is used to drive the rotary reduction motor 5 to rise or fall.

[0029] With the above design scheme, when spraying is required, the conveying component 2 controls the fire extinguisher bottle to come to the bottom of the spray gun 33. After the bottle mouth positioning ring 36 is put on the fire extinguisher bottle, the slider reduction motor 30 controls the spray gun 33 to insert into the fire extinguisher bottle. During the spraying process, the slider reduction motor 30 will also control the spray gun 33 to repeatedly rise and fall inside the fire extinguisher bottle to ensure that the resin can be evenly sprayed inside the fire extinguisher bottle.

[0030] With the above design, when the fire extinguisher bottle to be sprayed comes directly below the spray gun 33, the lifting cylinder 50 drives the rotary reduction motor 5 to lift up. The tray 52 above the lifted rotary reduction motor 5 will lift the fire extinguisher bottle until it touches the bottle mouth positioning ring 36. Then the rotary reduction motor 5 starts, and the tray 52 drives the fire extinguisher bottle to rotate. The rotating fire extinguisher bottle can spray the resin more evenly.

[0031] In this embodiment, the conveying assembly 2 includes a displacement cylinder 20, a displacement slide 21, and a bottle fixing ring 23; a transverse guide rail 22 is provided on the frame 1, the displacement cylinder 20 is installed on the frame 1, the displacement cylinder 20 is used to drive the displacement slide 21 to slide on the transverse guide rail 22, multiple sets of bottle fixing rings 23 are installed on the displacement slide 21, and the bottle fixing rings 23 correspond one-to-one with the bottle mouth positioning rings 36; a detachable bottle electromagnetic heating coil 4 is provided on the bottle fixing ring 23.

[0032] Through the above design scheme, the bottle-body electromagnetic heating coil 4 can heat the fire extinguisher bottle, increasing the internal temperature. The high temperature of the inner wall improves the resin adhesion, making the resin adhere more evenly to the inner wall. Simultaneously, the detachable bottle-body electromagnetic heating coil 4 can be replaced as needed to adapt to spraying fire extinguisher bottles of different sizes. The displacement cylinder 20 can push the fire extinguisher bottle under the spray gun 33 or move it away from under the spray gun 33. The bottle-body fixing ring 23 on the displacement slide 21 is used to fix the fire extinguisher bottle onto the displacement slide 21, preventing the fire extinguisher bottle from tipping over during the pushing process.

[0033] In this embodiment, a set of heating stations 10 are respectively provided at the front and rear ends of the frame 1, and the heating stations 10 correspond one-to-one with the bottle fixing rings 23. A set of conveying components 2 are respectively provided at the front and rear ends of the frame 1, and the heating stations 10 correspond to the conveying components 2. A bottle bottom heating cylinder 40 is installed at the heating station 10, and a bottle bottom electromagnetic heating coil 41 is provided above the bottle bottom heating cylinder 40.

[0034] With the above design scheme, when the displacement cylinder 20 moves the fire extinguisher bottle to the heating station 10, the bottle bottom heating cylinder 40 controls the bottle bottom electromagnetic heating coil 41 to rise, and works with the bottle body electromagnetic heating coil 4 to heat the fire extinguisher bottle located in the bottle body fixing ring 23 in all directions, so as to avoid the bottom temperature of the fire extinguisher bottle being too low and affecting the adhesion of the resin.

[0035] In this embodiment, a guide rod 51 is provided on the frame 1, and a lifting cylinder 50 is used to drive the rotary gear motor 5 to slide on the guide rod 51. The guide rod 51 can make the lifting process of the rotary gear motor 5 smoother, and at the same time ensure that the rotary gear motor 5 can rise or fall vertically under the drive of the lifting cylinder 50.

[0036] In this embodiment, a recovery chamber adjusting screw 35 is provided on the frame 1, which is used to adjust the height of the paint recovery chamber 34.

[0037] Through the above design, the paint recovery chamber 34 is used to house the spray gun 33. When the spray gun 33 is raised after spraying, the end of the spray gun 33 is pulled out of the fire extinguisher bottle and stops in the paint recovery chamber 34, preventing excess resin from dripping onto the frame 1 or the outer wall of the fire extinguisher bottle. At the same time, the paint recovery chamber 34 can also protect the spray gun 33, preventing dust and other impurities from contaminating the resin inside the spray gun 33. The operator can adjust the height of the paint recovery chamber 34 by rotating the recovery chamber adjusting screw 35 to accommodate fire extinguisher bottles of different heights. When it is necessary to perform internal spraying on fire extinguisher bottles of other models with different heights and diameters, the operator can replace the bottle body electromagnetic heating coil 4 with one of different sizes as needed, and then adjust the height of the paint recovery chamber 34 to meet different processing requirements.

[0038] In this embodiment, a guide ring 37 is provided above the paint recovery chamber 34, and the guide ring 37 is used to guide the spray gun 33.

[0039] With the above design, when it is necessary to spray the inner wall of the fire extinguisher bottle, the displacement cylinder 20 moves the displacement slide 21 to the heating station 10. The operator uses tools such as pliers to place the fire extinguisher bottle to be sprayed into the bottle body electromagnetic heating coil 4. At the same time, the bottle bottom heating cylinder 40 controls the bottle bottom heating electromagnetic coil to rise, which works in conjunction with the bottle body electromagnetic heating coil 4 to uniformly preheat the fire extinguisher bottle. After a certain period of time, the temperature of the fire extinguisher bottle rises, and the displacement cylinder 20 pushes the preheated fire extinguisher bottle to the spraying station. The lifting cylinder 50 drives the tray 52 and the rotary reduction motor 5 to lift until the fire extinguisher bottle touches the cylinder. The positioning ring 36 is activated, and the rotary reduction motor 5 starts rotating. The preheated fire extinguisher bottle is rotated through the tray 52. ​​Then, the spray gun 33 is lowered and inserted into the fire extinguisher bottle. During the spraying process, it repeatedly rises and falls inside the fire extinguisher bottle to ensure more even resin spraying. After the spraying operation is completed, the spray gun 33 retracts into the paint recovery chamber 34. At the same time, the rotary reduction motor 5 stops, and the lifting cylinder 50 controls the fire extinguisher bottle to fall. Then, the displacement cylinder 20 pulls the sprayed fire extinguisher bottle back to the heating station 10, making it convenient for the staff to take out the sprayed fire extinguisher bottle and put in the fire extinguisher bottle to be processed, and continue the spraying operation.

[0040] The water-based fire extinguisher bottle spraying machine provided by this utility model, compared with the prior art, can preheat the fire extinguisher bottle by using the bottom electromagnetic heating coil 41 and the bottle body electromagnetic heating coil 4, thereby increasing the temperature of the fire extinguisher bottle. During the spraying operation, the slider reduction motor 30 controls the spray gun 33 to enter the fire extinguisher bottle for spraying. The spray gun 33 will repeatedly rise and fall inside the fire extinguisher bottle under the drive of the slider reduction motor 30 to ensure that the resin is evenly sprayed into the inside of the fire extinguisher bottle. During this period, the fire extinguisher bottle will rotate at high speed under the drive of the rotary reduction motor 5. The preheated fire extinguisher bottle has a higher internal temperature, which will improve the adhesion of the resin. The combination of these two factors will make the resin more evenly distributed inside the bottle.

[0041] Where there is no conflict, the above embodiments and features can be combined with each other.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
