A water baffle 13 is fixedly connected to the middle of the top wall of the workbench 1, and a water vapor collection mechanism 2 is arranged on the left side of the bottom wall of the workbench 1;

[0040] Specifically, the conveyor component is started to convey the felt cloth after gluing into the interior of the workbench 1. At the same time, the water pump 6 is turned on. The water pump 6 extracts water from the water tank 5 and then pumps it into the shunt pipe 7. The shunt pipe 7 distributes the water into the upper water supply pipe 8 and the lower water supply pipe 10. A plurality of upper spray heads 11 are equidistantly communicated with the bottom wall of the upper water supply pipe 8, and a plurality of lower spray heads 12 are equidistantly communicated with the top wall of the lower water supply pipe 10. The water flow reaches the upper spray heads 11 through the upper water supply pipe 8 and sprays downward from the upper spray heads 11. At the same time, it reaches the lower spray heads 12 through the lower water supply pipe 10 and sprays upward from the lower spray heads 12 to perform a water spraying operation on the lower surface of the felt cloth. The design of the upper and lower opposite spray heads can ensure that both the upper and lower surfaces of the felt cloth can be fully sprayed. The water baffle 13 fixedly connected to the middle of the top wall of the workbench 1 can prevent water from splashing everywhere during the water spraying process, ensure the cleanliness of the working environment, and make the sprayed water concentrate on the felt cloth as much as possible, improving the water spraying efficiency. The automatic water spraying operation for the felt cloth after gluing is realized, improving the efficiency and quality of the felt cloth water spraying operation and reducing the complexity and uncertainty of manual operation.

[0041] Referring to Figure 1 , Figure 4 and Figure 5 , the water vapor collection mechanism 2 includes a suction fan 201. The top end of the suction fan 201 is communicated with a long suction groove 202. The long suction groove 202 penetrates through the workbench 1 and is fixedly connected to the left side of the inner bottom wall of the groove 9. The front side of the top end of the suction fan 201 is communicated with a suction pipe 203. The top end of the suction pipe 203 is communicated with a collection plate 204. The collection plate 204 is in an inclined state, and a plurality of water baffle strips 205 are fixedly connected to the bottom wall. A plurality of suction holes 206 are equidistantly opened in the middle of the bottom wall of the collection plate 204. The plurality of suction holes 206 are all communicated with the suction pipe 203. A filter barrel 207 is fixedly connected to the left side of the top wall of the carrier plate 4.

The top end of the return pipe 208 is communicated with the front side bottom end of the inner wall of the groove 9. The filter barrel 207 is communicated with the left bottom end of the water tank 5 through a water pipe;

[0042] Specifically, during the operation of the automatic sprinkler device, a large amount of water vapor is generated due to the water spraying operation on the felt cloth. By starting the suction fan 201, the long suction groove 202 begins to suck the water vapor in the water baffle 13. The long suction groove 202 penetrates through the workbench 1 and is fixedly connected to the left side of the inner bottom wall of the groove 9, which can effectively collect the water vapor in the area near the workbench 1. At the same time, the suction fan 201 is connected to the inclined collecting plate 204 through the suction pipe 203. Multiple water baffle strips 205 on the bottom wall of the collecting plate 204 can prevent the water droplets sprayed by the lower sprinkler 12 from directly spraying into the suction holes 206, and the suction holes 206 convey the collected water vapor to the suction pipe 203. After the suction fan 201 sucks in the water vapor, it conveys the water vapor to the filter barrel 207 through the water pipe. At the same time, the water accumulated at the bottom of the groove 9 is conveyed to the filter barrel 207 through the return pipe 208. The filter barrel 207 filters the water vapor and water, removing the impurities therein. The water after filtration flows into the water tank 5 through the water pipe, realizing the recycling of water. The water vapor collection mechanism 2 can not only reduce the water vapor content in the working environment, keep the working environment dry, but also filter the collected water and send it back to the water tank 5, improving the utilization rate of water resources, reducing the operation cost of the automatic sprinkler device, and preventing the water vapor from diffusing upward and affecting the use of the device.

[0043] Refer to Figure 1 and Figure 2 , the conveying assembly includes a rotating motor 14. The output end of the rotating motor 14 is fixedly connected with a driving gear 15. The top of the driving gear 15 is meshed and connected with a driven gear 16. Both the driving gear 15 and the driven gear 16 are fixedly connected with conveying rollers 17 at the rear ends. The rear ends of the two conveying rollers 17 are rotatably connected to the inner rear side of the workbench 1; the right end of the front side of the top wall of the workbench 1 is fixedly connected with a horizontal frame 18. A plurality of spirit levels 19 are fixedly connected to the inner wall of the horizontal frame 18; the bottom ends of the plurality of fixing columns 3 are all fixedly connected with anti-slip pads 20. The plurality of anti-slip pads 20 are all in the shape of being smaller at the top and larger at the bottom, and the bottom is circular;

[0044] Specifically, the rotating motor 14 in the conveying assembly provides power, drives the driven gear 16 to rotate through the driving gear 15, so that the two conveying rollers 17 rotate synchronously, realizing the stable and accurate conveying of the felt cloth after glue rolling to the water spraying area of the workbench 1, ensuring that the felt cloth can continuously perform the water spraying operation in the automatic sprinkler device, improving the production efficiency. The horizontal frame 18 provides an installation position for the plurality of spirit levels 19, and the spirit levels 19 can monitor the horizontal state of the workbench 1 in real time, ensuring the uniformity and stability of water spraying. The anti-slip pads 20 at the bottom ends of the fixing columns 3 are smaller at the top and larger at the bottom and the bottom is circular, which can increase the contact area with the ground, improve the stability of the device, and at the same time, the anti-slip pads 20 can effectively prevent the automatic sprinkler device from sliding due to the vibration generated during the spraying process.

[0045] Refer to Figure 1, at the front left end of the top wall of the workbench 1, a control console 21 is fixedly connected, and a plurality of control buttons 22 are fixedly connected to the top of the control console 21; in the middle of the front side of the top wall of the workbench 1, a water pressure gauge 23 is fixedly connected, and the water pressure gauge 23 is electrically connected to the control console 21; anti-collision gaskets 24 are fixedly connected to the four corners of the top wall of the workbench 1, and an observation window 25 is arranged on the front side of the water baffle 13, and the observation window 25 is installed using transparent glass;

[0046] Specifically, the control console 21 serves as the signal concentration panel of the entire device. The multiple control buttons 22 on its top can control the suction fan 201, the water pump 6, and the rotating motor 14 to meet different production requirements. The water pressure gauge 23 is electrically connected to the control console 21 and can display the water spraying pressure value in real time. The operator can understand the water spraying pressure situation at any time through the control console 21 so as to make adjustments according to the material of the felt cloth and the water spraying requirements. The anti-collision gaskets 24 at the four corners of the top wall of the workbench 1 can prevent personnel from being accidentally injured by colliding with the corners of the workbench 1 during operation. The observation window 25 on the front side of the water baffle 13 is installed using transparent glass, which is convenient for the operator to observe the water spraying situation of the felt cloth in real time without opening the water baffle 13, so as to timely discover problems and make adjustments.

[0047] Working principle: The felt cloth after glue rolling is conveyed into the workbench 1 by starting the conveying component. At the same time, the water pump 6 is started. The water pump 6 extracts water from the water tank 5 and then pumps it into the shunt pipe 7. The shunt pipe 7 distributes the water to the upper water supply pipe 8 and the lower water supply pipe 10. A plurality of upper spray heads 11 are equidistantly communicated with the bottom wall of the upper water supply pipe 8, and a plurality of lower spray heads 12 are equidistantly communicated with the top wall of the lower water supply pipe 10. The water flow reaches the upper spray heads 11 through the upper water supply pipe 8 and sprays downward from the upper spray heads 11. At the same time, it reaches the lower spray heads 12 through the lower water supply pipe 10 and sprays upward from the lower spray heads 12 to perform a water spraying operation on the lower surface of the felt cloth. The design of the upper and lower opposite spray heads can ensure that both the upper and lower surfaces of the felt cloth can be fully water-sprayed. The water baffle 13 fixedly connected to the middle of the top wall of the workbench 1 can prevent water from splashing everywhere during the water spraying process, ensure the cleanliness of the working environment, and make the sprayed water as concentrated on the felt cloth as possible to improve the water spraying efficiency;

[0048] Moreover, during the operation of the automatic sprinkler device, a large amount of water vapor is generated due to the water spraying operation on the felt cloth. By starting the suction fan 201, the long suction groove 202 begins to suck the water vapor in the water baffle 13. The long suction groove 202 penetrates through the workbench 1 and is fixedly connected to the left inner bottom wall of the groove 9, which can effectively collect the water vapor in the area near the workbench 1. At the same time, the suction fan 201 is connected to the inclined collecting plate 204 through the suction pipe 203. Multiple water baffle strips 205 on the bottom wall of the collecting plate 204 can prevent the water droplets sprayed by the lower nozzle 12 from directly spraying into the suction holes 206, and the suction holes 206 convey the collected water vapor to the suction pipe 203. After the suction fan 201 sucks in the water vapor, it conveys the water vapor to the filter barrel 207 through a water pipe. At the same time, the water accumulated at the bottom of the groove 9 is conveyed to the filter barrel 207 through the return pipe 208. The filter barrel 207 filters the water vapor and water to remove the impurities therein. The water after filtration flows into the water tank 5 through a water pipe, realizing the recycling of water.
