The cleaning device includes a cleaning material tank, a water pump, a three-way connecting pipe, and a switch.

[0004] The above technical solution includes an A-type material tank that provides raw materials to the mixing motor; a stirring motor that stirs the raw materials to prevent sedimentation; a screw pump that provides power for conveying the raw materials; a mixing motor that mixes the two raw materials; a B-type material tank that stores type B adhesive; and a cleaning device that cleans the adhesive in the mixing chamber to prevent it from hardening and clogging the chamber. However, simple rinsing of the inner wall of the grouting tank cannot remove the sticky solution inside, and it is not possible to perform scraping cleaning while rinsing to fully coordinate internal cleaning. Utility Model Content

[0005] The purpose of this invention is to provide an automatic cleaning device for a glue dispensing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic cleaning device for a glue dispensing machine includes a glue dispensing machine body, a grouting tank on the upper surface of the glue dispensing machine body, a water storage tank on the side of the grouting tank, a delivery pump on the upper surface of the water storage tank, a top cover on the top of the glue dispensing machine body, columns symmetrically arranged on the top cover, a scraper assembly for internal scraper cleaning between the columns, a positioning plate on the top of the columns, and electric push rods symmetrically arranged on the upper surface of the positioning plate.

[0008] The bottom of the grouting tank is equipped with a drain pipe that communicates with the interior. The drain pipe extends out from one side of the glue dispensing machine body and is equipped with a butterfly valve at the end of the drain pipe. A glue dispensing pipe is provided on the outer wall of the grouting tank near the bottom.

[0009] The scraper assembly includes a lifting plate and a motor located at the center of the upper surface of the lifting plate. The output shaft of the motor passes through the lifting plate and is coaxially connected to a main shaft at its end. A scraper is located at the bottom of the main shaft, and scraper blades are located at both ends of the scraper.

[0010] A sealing gasket is provided on the lower surface of the top cover, and an annular nozzle is provided below the sealing gasket. Several nozzles are provided on the outer wall of the annular nozzle, and the annular nozzle is connected to the delivery port of the delivery pump through a connecting pipe.

[0011] Furthermore, the upper surface of the glue dispensing machine body is symmetrically provided with two glue storage tanks. The glue storage tanks extend into the grouting tank through two conveying pipes, and the conveying pipes of the glue storage tanks are provided with valves at the end near the grouting tank.

[0012] In this invention, the adhesive storage tank stores different adhesives and transports them separately. With the help of valves, the valves are closed to prevent the mixed liquid inside the grouting tank from flowing back into the adhesive storage tank and contaminating the original adhesive. The adhesive storage tank is transported to the corresponding adhesive by an external pump.

[0013] Specifically, the bottom of the grouting bucket is fixed to the top of the glue dispensing machine body with screws, the water storage tank is fixedly connected to the grouting bucket with screws, the delivery pump is fixedly connected to the water storage tank with screws, and the pumping pipe of the delivery pump extends into the water storage tank.

The sealing element is made of alkali-resistant rubber, achieving a seal between the main shaft and the top cover without affecting the rotational engagement between the main shaft and the sealing element, thus increasing the sealing performance between the top cover and the grouting tank.

[0019] The ring-shaped nozzle is equipped with multiple nozzles to uniformly spray the inner wall of the grouting tank. The connecting pipe is connected to the delivery pump to continuously deliver the cleaning fluid to the inside of the grouting tank for internal spraying and cleaning.

[0023] In this invention, the motor is electrically connected to an external power source via a wire. When the control switch is activated, the output shaft rotates, driving the main shaft to rotate. When the scraper contacts the bottom of the grouting bucket, it scrapes the adhesive solution on the bottom surface. The scraper is arc-shaped, and the outer wall of the scraper is close to the inner wall of the grouting bucket, scraping the adhesive solution on the inner wall.

[0027] 1. This utility model features a grouting tank with a water storage container. A delivery pump provides power to transport the cleaning fluid, guiding it from the connecting pipe into the annular spray nozzle. Multiple nozzles work together to spray and clean the inner wall of the grouting tank. A positioning plate with an electric push rod, in conjunction with the column, allows the telescopic arm to extend or retract, enabling the scraper assembly to move up and down between the columns. The motor starts the main shaft to rotate continuously. With the cooperation of the scraper and the shovel, the sticky solution on the inner wall of the grouting tank is scraped, increasing the thoroughness of cleaning the inner wall. The mixed solution after cleaning the inner wall of the grouting tank is discharged and collected through the drain pipe.

[0028] 2. This utility model uses a glue-filling pipe to discharge the grouting liquid from the grouting tank. The main body of the grouting machine controls the start of the electric push rod, the delivery pump, and the motor. The two glue storage cylinders on the main body of the grouting machine are pumped with glue by a liquid pump. When it is necessary to clean the inside of the grouting tank, the ends of the delivery pipes of the two glue storage cylinders are closed, the lifting plate moves, and with the cooperation of the scraper and the shovel, and with the help of the sprayed cleaning liquid, the cleaning is automatically performed. After cleaning is completed, the butterfly valve opens, and the cleaning mixture is discharged from the drain pipe and collected. Attached Figure Description
