[0020] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0021] The present application provides a coating agent spraying device.

[0022] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the coating agent spraying device includes a sprayer 100 , a spraying assembly 200 and a cleaning assembly 300 .

[0023] A spray chamber 101 is defined in the middle of the spray machine 100. The spray assembly 200 includes a conveyor belt 201, a support plate 202, a telescopic arm 203, and a spray port 204. The conveyor belt 201 is fixedly connected to the side wall of the spray machine 100, one end of the telescopic arm 203 is fixedly connected to the conveyor belt 201, the support plate 202 is fixedly connected to the other end of the telescopic arm 203, and the spray port 204 is fixedly connected to the top surface of the spray chamber 101. The cleaning component 300 includes a recovery chamber 301, a water spray port 302, a filter plate 303, a drive motor 304, an oil pushing plate 305 and a recovery chamber 306. The recovery chamber 301 is arranged on the bottom surface of the sprayer 100 and is connected to the spray chamber 101. The water spray port 302 is fixedly connected to the top surface of the spray chamber 101. The filter plate 303 is vertically arranged in the recovery chamber 301. The drive motor 304 is arranged on the side wall of the filter plate 303. One end of the oil pushing plate 305 is fixedly connected to the drive rod of the drive motor 304. The recovery chamber 306 is arranged at the end of the recovery chamber 301.

[0024] In this embodiment, the raw material is placed on the top surface of the support plate 202, and the support plate 202 is moved by the conveyor belt 201, so that the raw material passes through the spray chamber 101. During the passage, the spray port 204 sprays the coating agent to the raw material. Since the specifications of the raw materials are different, the length of the telescopic arm 203 can be adjusted, and then the distance between the two support plates 202 can be adjusted, so that raw materials of different specifications can be fixed on the support plate 202. After the spraying is completed, water is sprayed into the spray chamber 101 through the water spray port 302 to complete the cleaning of the spray chamber 101. The wastewater and coating agent generated by the cleaning flow into the recovery chamber 301, and the driving motor 304 pushes the oil push plate 305 to move, so that the coating agent is separated from the wastewater. The separated wastewater enters the recovery chamber 306 to complete the recovery.

[0025] like Figure 2 As shown, in one embodiment of the present application, the telescopic arm 203 includes a sliding portion 203a and a fixed portion 203b, one end of the fixed portion 203b is fixedly connected to the conveyor belt 201, and the other end of the fixed portion 203b is provided with a slide groove 203c, one end of the sliding portion 203a is slidably connected to the slide groove 203c, and the support plate 202 is fixedly connected to the other end of the sliding portion 203a.

[0026] In this embodiment, the position of the support plate 202 is adjusted by adjusting the length of the telescopic arm 203 , so that the support plate 202 can be suitable for raw materials of different widths.

[0027] Move the sliding portion 203a along the slide groove 203c toward the bottom surface of the fixed portion 203b, thereby shortening the total length of the telescopic arm 203 and increasing the distance between the two support plates 202, so that raw materials with a larger width can be placed on the two support plates 202 and the spraying of the raw materials can be completed.

[0028] Move the sliding portion 203a along the slide groove 203c away from the bottom surface of the fixed portion 203b, thereby increasing the total length of the telescopic arm 203, thereby reducing the distance between the two support plates 202, so that raw materials with smaller widths can be placed on the two support plates 202 and the spraying of the raw materials can be completed.

[0029] like Figure 2 As shown, in one embodiment of the present application, there are multiple telescopic arms 203, and two conveyor belts 201 are provided. The two conveyor belts 201 are symmetrically arranged about the central axis of the sprayer 100, and each conveyor belt 201 is fixedly connected to at least one telescopic arm 203.

[0030] In this embodiment, the conveyor belt 201 drives the support plate 202 to move, so that the raw material gradually passes through the spraying chamber 101 under the drive of the support plate 202 and completes the spraying process.

[0031] Since the raw material is placed on the top surface of the support plate 202 and the spray port 204 is located on the top surface of the spray chamber 101, there is no other component blocking the spray port 204 and the raw material, thereby ensuring comprehensive spraying of the raw material and avoiding missed spraying areas.

[0032] like Figure 2 As shown, in one embodiment of the present application, the filter plate 303 is arranged between the recovery chamber 301 and the recovery chamber 306, and the filter plate 303 includes a built-in cavity 303a and a solid part 303b, and the built-in cavity 303a is arranged on the upper side of the solid part 303b.

[0033] In this embodiment, the recovery chamber 306 is separated from the recovery cavity 301 by the filter plate 303, and the larger volume impurities contained in the wastewater are filtered, which has the effect of preliminary filtration, so that the wastewater entering the recovery chamber 306 does not contain large volume impurities.

[0034] The internal cavity 303 a provides a space for storing the hydraulic cylinder 308 , and the solid portion 303 b can block the passage of wastewater, so that the wastewater can only enter the recovery chamber 306 through the filter hole 311 .

[0035] like Figure 1 As shown, in one embodiment of the present application, a sliding groove 312 is opened on the side wall of the filter plate 303, and the sliding groove 312 is connected to the built-in cavity 303a.

[0036] In this embodiment, since the hydraulic cylinder 308 drives the push plate 309 to move up and down, a sliding groove 312 is provided so that the hydraulic rod of the hydraulic cylinder 308 can move smoothly.

[0037] like Figure 3 As shown, in one embodiment of the present application, the coating agent spraying device also includes a lifting member 307, and the lifting member 307 includes a hydraulic cylinder 308 and a push plate 309. The bottom surface of the hydraulic cylinder 308 is fixedly connected to the bottom surface of the built-in cavity 303a, and the driving rod of the hydraulic cylinder 308 extends to the outside of the filter plate 303 through the sliding groove 312. One end of the push plate 309 is fixedly connected to the hydraulic rod of the hydraulic cylinder 308, and the bottom surface of the drive motor 304 is fixedly connected to the top surface of the push plate 309.

[0038] In this embodiment, since the height of the liquid level in the recovery chamber 301 is gradually reduced, in order to ensure that the oil push plate 305 can always maintain contact with the liquid surface, the hydraulic cylinder 308 drives the push plate 309 to move up and down, thereby driving the drive motor 304 located on the top surface of the push plate 309 to move up and down, so that the oil push plate 305 moves along with the movement of the drive motor 304, thereby ensuring that the oil push plate 305 can always maintain contact with the liquid surface.

[0039] like Figure 2 As shown, in one embodiment of the present application, there are multiple water spraying ports 302 , and the water spraying ports 302 are arranged at intervals from the spraying ports 204 .

[0040] Specifically, the water outlet 302 is connected to an external water source.

[0041] In this embodiment, after spraying is completed, in order to clean the spray chamber 101, water is sprayed into the cleaning chamber through the water nozzle 302 to clean the spray chamber 101. The waste water generated by cleaning will flow into the recovery chamber 301 at the bottom of the sprayer 100, and enter the recovery chamber 306 after passing through the filter plate 303.

[0042] like Figure 1 As shown, in one embodiment of the present application, the cleaning assembly 300 further includes a scraper 310 , one end of which is fixedly connected to the cavity wall of the recovery cavity 301 , and the other end of the scraper 310 abuts against the bottom surface of the oil pushing plate 305 .

[0043] In this embodiment, after the water spray port 302 cleans the spray chamber 101, the coating agent and wastewater will flow into the recovery chamber 301 together. Since the density of the coating agent is less than that of water, the coating agent will float on the surface of the wastewater. The driving motor 304 pushes the oil pushing plate 305 to move, so that the oil pushing plate 305 pushes away the coating agent on the surface of the wastewater during the movement, thereby preventing the coating agent from entering the recovery chamber 306.

[0044] Since a large amount of coating agent will adhere to the bottom surface of the oil pushing plate 305 after long-term use, if the oil pushing plate 305 is not cleaned in time, the working efficiency of the oil pushing plate 305 will be reduced. Therefore, a scraper 310 is provided to scrape off the coating agent attached to the bottom surface of the oil pushing plate 305.

[0045] When using the scraper 310, you only need to adjust the height of the oil pushing plate 305 so that the bottom surface of the oil pushing plate 305 is against the scraper 310, and repeatedly drive the oil pushing plate 305 to move by the driving motor 304, so that the coating agent can be separated from the bottom surface of the oil pushing plate 305 under the action of the scraper 310, thereby completing the cleaning of the oil pushing plate 305.

[0046] like Figure 2 As shown, in one embodiment of the present application, a plurality of spray ports 204 are provided, and the plurality of spray ports 204 are arranged at equal intervals on the top surface of the spray chamber 101 , and the support plate 202 is located below the spray ports 204 .

[0047] In this embodiment, the raw materials are sprayed separately through the multiple spray ports 204, thereby avoiding spraying dead angles and improving spraying efficiency.

[0048] like Figure 1 As shown, in one embodiment of the present application, the solid portion 303 b of the filter plate 303 is provided with a plurality of filter holes 311 , and the plurality of filter holes 311 are arranged on the solid portion 303 b of the filter plate 303 at equal intervals.

[0049] In this embodiment, wastewater enters the recovery chamber 306 through the filter hole 311. Since the oil pushing plate 305 pushes away the coating agent on the surface of the wastewater, only the wastewater enters the recovery chamber 306, thereby completing the separation of the wastewater and the coating agent.

[0050] The various technical features of the above-described embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. In order to make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
