Description

Technical Field

[0001] This utility model relates to the technical field of slurry preparation devices, specifically a slurry preparation device for luminous advertising characters. Background Technology

[0002] Illuminated advertising signs are a type of illuminated sign widely used in commercial advertising, branding, and outdoor advertising. They emit light through a built-in light source (usually LEDs) to attract attention and convey information. During production, liquid resin or acrylic material is typically sprayed into a specific mold, and then cured quickly using UV curing light.

[0003] The slurry is typically poured into a reservoir, then pumped out and injected into the mold using a spray pump. However, after one letter is completed, residual slurry often overflows when the spray gun moves to the next letter. This not only causes slurry to stick to the workbench, affecting the cleanliness of the work environment, but also results in significant waste of slurry. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for luminous advertising lettering slurry. Through a reflux system, the slurry in the spray pipe is returned to the sleeve, and the slurry in the spray gun is also returned, thus preventing the liquid in the spray gun from dripping when the spray gun moves to the next letter.

[0005] To address the problems of existing technologies, this utility model provides a mixing device for luminous advertising letter slurry, comprising a main body, inside which a detachable storage cylinder for storing slurry is installed. Near the bottom of the storage cylinder inside the main body, a spraying system for extracting slurry from the storage cylinder is also provided. The spraying system includes a spray pump, the outlet end of which is connected to a spray pipe, one end of which is connected to a spray gun. The inlet end of the spray pump is also connected to a connecting pipe, and a sleeve is connected to the connecting pipe. The spraying system further includes a return system for drawing slurry remaining in the spray gun into the sleeve, and a cleaning system for cleaning slurry from the spray pipe.

[0006] Preferably, the reflux system includes a reflux pump fixed in the main body, the inlet end of the reflux pump is connected to a second reflux pipe, one end of the second reflux pipe is connected to the spray pipe, the outlet end of the reflux pump is connected to a first reflux pipe, and one end of the first reflux pipe is connected to the sleeve.

[0007] Preferably, a fourth solenoid valve is also connected to the second return pipe, and a first solenoid valve is also connected to the spray pipe at the location of the spray pump. After a character is sprayed, the first solenoid valve closes and the fourth solenoid valve opens, allowing the slurry to flow from the first return pipe into the sleeve.

[0008] Preferably, the cleaning system includes an air pump fixed on the main body, an air outlet pipe connected to the air pump's outlet end, one end of the air outlet pipe connected to a connecting pipe, and an air inlet pipe connected to the air pump's inlet end.

[0009] Preferably, a third solenoid valve is provided on the air outlet pipe, and a second solenoid valve is connected to the connecting pipe. When the second solenoid valve is closed and the third solenoid valve is open, gas can flow into the spray pipe to clean the slurry in the spray pipe.

[0010] Preferably, the bottom of the liquid storage cylinder is also connected to an insertion interface, one end of which can be inserted into the sleeve.

[0011] Preferably, the top of the main body is rotatably provided with a top cover, and the front of the main body is provided with a spray gun holder.

[0012] Preferably, a control system is provided on the side of the main body away from the liquid storage cylinder, and casters are fixed at the four corners of the bottom of the main body.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. This application includes a recirculation system comprising a recirculation pump. After the spray gun completes the spraying of one character, the first solenoid valve closes, and the spray pump stops. At this time, the fourth solenoid valve opens, the recirculation pump starts, drawing the slurry in the spray tube back to the sleeve, and ultimately returning it to the storage tank. Simultaneously, the slurry in the spray gun also flows back, effectively preventing slurry dripping.

[0015] 2. This application incorporates a cleaning system. When the mixing device finishes spraying the lettering, to prevent slurry residue in the pipes from clogging them, the second solenoid valve closes and the third solenoid valve opens. Subsequently, by starting the air pump, air enters the spray pump, which then sprays the slurry out of the spray pipe. Another portion of the gas enters through the second return pipe, causing the slurry in the second return pipe to flow from the first return pipe into the sleeve and then into the storage cylinder, facilitating subsequent cleaning.

[0016] 3. The liquid storage cylinder and the main body of this application are detachably connected. The liquid storage cylinder can be taken out from the main body, and the insertion interface is separated from the sleeve, which makes it easy to remove the liquid storage cylinder for cleaning.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-6 As shown, this utility model provides a mixing device for luminous advertising lettering slurry, including a main body 1. A detachable storage cylinder 3 for storing the slurry is installed inside the main body 1. Near the bottom of the storage cylinder 3, a spraying system 2 is also provided inside the main body 1 for extracting the slurry from the storage cylinder 3. The spraying system 2 includes a spray pump 21, with a spray pipe 211 connected to the outlet end of the spray pump 21. One end of the spray pipe 211 is connected to a spray gun 212, and a connecting pipe 213 is connected to the inlet end of the spray pump 211. A sleeve 214 is connected to the connecting pipe 213. The spray pump 21 provides power to extract and pressurize the slurry from the storage cylinder 3 so that it can be sprayed out through the spray pipe 211. The spraying system 2 also includes a return system 23 for drawing the slurry remaining in the spray gun 212 into the sleeve 214, and a cleaning system 22 for cleaning the slurry in the spray pipe 211.

[0026] The reflux system 23 includes a reflux pump 231 fixed in the main body 1. The inlet end of the reflux pump 231 is connected to a second reflux pipe 233, one end of which is connected to the spray pipe 211. The reflux pump 231 provides power to pump the residual slurry in the spray pipe 211 back to the sleeve 214. The outlet end of the reflux pump 231 is connected to a first reflux pipe 232, one end of which is connected to the sleeve 214.

[0027] A fourth solenoid valve 2331 is also connected to the second return pipe 233. A first solenoid valve 2111 is also connected to the spray pipe 211 at the location where it connects to the spray pump 21. After a character is sprayed, the first solenoid valve 2111 closes, cutting off the connection between the spray pipe 211 and the spray pump 21, preventing the slurry from continuing to flow from the spray pump 21 to the spray gun 212. After a character is sprayed, the first solenoid valve 2111 closes, and the fourth solenoid valve 2331 opens, allowing the slurry to flow from the first return pipe 232 into the sleeve 214.

[0028] After the spray gun 212 completes the spraying of one character, the first solenoid valve 2111 closes, and the spray pump 21 stops. At this time, the fourth solenoid valve 2331 opens, the return pump 231 starts, and the slurry in the spray pipe 211 is drawn back to the sleeve 214, and finally flows back to the storage tank 3. At the same time, the slurry in the spray gun 212 also flows back, effectively preventing slurry dripping.

[0029] The cleaning system 22 includes an air pump 221 fixed on the main body 1. The air outlet of the air pump 221 is connected to an air outlet pipe 222, one end of which is connected to a connecting pipe 213. The air inlet of the air pump 221 is connected to an air inlet pipe 223. A third solenoid valve 2221 is installed on the air outlet pipe 222, and a second solenoid valve 2131 is connected to the connecting pipe 213. When the second solenoid valve 2131 is closed and the third solenoid valve 2221 is open, gas can flow into the spray pipe 211 to clean the slurry in the spray pipe 211.

[0030] When the mixing device finishes spraying the lettering, in order to prevent the slurry residue in the pipeline from clogging the pipeline, the second solenoid valve 2131 is closed and the third solenoid valve 2221 is opened. Then, by starting the air pump 221, the air pump 221 introduces air into the spray pump 21, and then sprays the slurry out from the spray pipe 211. Another part of the gas enters from the second return pipe 233, and the slurry in the second return pipe 233 enters from the first return pipe 232 into the sleeve 214 and then into the storage cylinder 3 for easy subsequent cleaning.

[0031] The bottom of the liquid storage cylinder 3 is also connected to an insertion interface 31, one end of which can be inserted into the sleeve 214. The liquid storage cylinder 3 can be removed from the main body 1, and the insertion interface 31 is separated from the sleeve 214, making it easy to remove the liquid storage cylinder 3 for cleaning.

[0032] The main body 1 is also equipped with a top cover 13 that rotates on top, and a spray gun holder 12 is also provided at the front of the main body 1. A control system 11 is provided on the side of the main body 1 away from the liquid storage cylinder 3, and casters 14 are fixed at the four corners of the bottom of the main body 1.

[0033] Working Principle: In use, first insert the liquid storage cylinder 3 into the main body 1, with the connector 31 aligning with the sleeve 214. Then, pour the slurry into the storage cylinder 3. After starting the spray pump 21, it draws the slurry from the storage cylinder 3 into the spray pipe 211. The slurry is then sprayed from the spray gun 212 and enters the font area of ​​the mold. When the spray gun 212 completes the spraying of one font, the first solenoid valve 2111 closes, and the spray pump 21 stops working. At this time, the fourth solenoid valve 2331 opens, and the return pump 231 starts, drawing the remaining slurry in the spray pipe 211 back to the sleeve 214, and finally back into the storage cylinder 3. Simultaneously, the slurry in the spray gun 212 also flows back, effectively preventing slurry dripping. After the mixing device completes the spraying of all fonts, to prevent slurry residue in the pipes from causing blockage, the second solenoid valve 2131 closes, and the third solenoid valve 2221 opens. Subsequently, the air pump 221 is started, allowing air to enter the spray pump 21. The air propels the slurry out of the spray pipe 211, completing the initial cleaning of the pipeline. At the same time, another part of the gas enters from the second return pipe 233, pushing the slurry therein through the first return pipe 232 into the sleeve 214, and finally returning to the storage cylinder 3.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
