Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting equipment production, in particular to automatic spraying equipment for a fire extinguisher bottle. Background Art

[0002] As a common fire prevention facility, fire extinguishers are widely used in various public places and areas with potential fire risks. The cylinder body serves as a carrier for fire extinguishing agents and highly compressed driving gases. After the cylinder is produced, it needs to be sprayed with paint on its surface to avoid oxidation and rust on the surface, thereby extending its storage and use time. The corrosion resistance of the bottle body can be enhanced by painting, and eye-catching appearance logos can be sprayed to ensure that it can be quickly identified and used in an emergency.

[0003] At present, automatic spraying is usually adopted for fire extinguisher bottles. The bottles are hung by hooks to enter the spraying equipment. The nozzles are located on both sides of the bottles for spraying. The bottles rotate during movement to complete the spraying around the bottles. The bottles rotate during movement and often lose balance and shake during rotation due to the unfixed hanging part. This will cause uneven spraying thickness of the bottles. Moreover, because there is no shielding between the bottles at the spraying point, the paint mist sprayed by the nozzles will continuously adhere to other bottles, resulting in inconsistent spraying thickness of the bottles, affecting the spraying quality. It will also cause inconsistent drying and curing time, affecting the curing effect. Therefore, an automatic spraying equipment for fire extinguisher bottles is proposed to solve the above problems. Summary of the invention

The present invention is provided with a fixed air suction hood and a movable air suction hood, wherein a spraying module is arranged inside the fixed air suction hood and the movable air suction hood, and a spray head is arranged in the spraying module. When the moving block rotates, the sliding plate is driven to move up and down, and the sliding plate is driven to move the sleeve ring, so that the sleeve ring drives the spray head to rotate along the rotating column connected to the connecting ring, thereby causing the nozzle of the spray head to swing up and down.

[0016] 2. The present invention is provided with a fixed air suction hood and a movable air suction hood.

The fixed air suction hood and the movable air suction hood fit together to cover the outside of the fire extinguisher bottle, and atomized paint is sprayed on the fire extinguisher bottle through the spray module. The fan in the collecting box generates negative pressure to suck the excess paint mist inside the fixed air suction hood into the collecting box for collection.

[0017] 3. The present invention is provided with a clamping assembly, and the bottle body fixing block inside the external connecting column can rotate to both sides under the squeezing of the push rod, and then can clamp the fire extinguisher bottle mouth to fix the fire extinguisher bottle, and the second spring provides elastic force to the limit moving block so that the limit moving block is close to the push rod, and the positioning block fixed on the push rod will be stuck between the limiting teeth to prevent the push rod from moving upward and limit the push rod. By setting a plurality of limiting teeth, the expansion angle of the bottle body fixing block can be adjusted in multiple stages to adapt to fire extinguisher bottles of different specifications. When the fire extinguisher bottle needs to be released, it is only necessary to pull the handle to both sides to make the positioning block disengage from the limiting teeth, and the push rod moves upward under the elastic force of the first spring, and the bottle body fixing blocks approach each other under the elastic force of the tensioning spring to release the fire extinguisher bottle. Compared with the hanging method, the fire extinguisher bottle is clamped by the two bottle body fixing blocks without shaking during the rotation spraying process of the fire extinguisher, the spraying thickness is consistent, and the spraying effect is better.

A plurality of filter cottons 57 are arranged on the side of the fan 56 close to the collecting box 5. The residual paint mist and water vapor are filtered by the filter cotton 57.

[0028] The principle of the present invention is as follows: the clamping assembly 4 is driven to move to the clamping position by the transfer assembly 3, and the positioning module 33 drives the mobile positioning block 331 to extend to position the clamping assembly 4. After the mouth of the fire extinguisher bottle is sleeved on the outside of the bottle body fixing block 42, the pneumatic telescopic column 32 drives the telescopic rod 321 to extend and push the push rod 43 downward, so that the extrusion block 431 moves downward to squeeze the bottle body fixing block 42, so that the tensioning spring 421 rotates to both sides to expand outward to clamp the bottle mouth of the fire extinguisher bottle, thereby fixing the fire extinguisher. When the clamping assembly 4 drives the fire extinguisher bottle to move above the fixed air suction hood 21, it is positioned through the positioning module 33, and the second driving motor 34 is started to drive the driving gear 35 to rotate and then drive the external connecting column 41 to rotate along the sliding block 413, and then the driving cylinder 223 is started to push the mobile air suction hood 22 to approach the fixed air suction hood 21 and fit the fixed air suction hood 21, and then the air suction hood 21 is started. The first driving motor 238 drives the turntable 236 to rotate, and then drives the sliding plate 235 to move up and down along the sliding limit plate 2351, so that the nozzle 234 swings, and the atomized paint is sprayed out to spray the surface of the fire extinguisher bottle. The swing prevents the accumulation of paint in the spraying area, so that the surface spraying thickness is consistent, and the fan 56 generates negative pressure to suck the residual paint mist into the collection box 5. The paint mist enters the collection box 5 through the connecting pipe 51 and contacts the guide plate 52. After being guided by the guide plate 52, it moves to one side, and the atomizing nozzle 54 sprays water mist. The paint mist and water mist are mixed and contact the baffle 53. The baffle 53 is provided with a plurality of through holes, so that the mixed mist can condense and fall into the collection box 5 for collection. This not only avoids the paint mist from diffusing to the outside and contacting other fire extinguisher bottles to cause inconsistent spraying thickness, but also reduces the paint mist from diffusing to the outside to pollute the environment and the health of the operators.

[0029] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.

[0030] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
