Technical Field
[0001] This utility model relates to the field of mooncake production technology, specifically to an egg wash applicator for mooncake production. Background Technology
[0002] Mooncakes, also known as moon cakes, harvest cakes, reunion cakes, etc., are a traditional Chinese delicacy that carries rich cultural connotations and people's yearning for reunion and happiness. During the mooncake production process, to increase the mooncake's luster and impart an egg aroma, an egg wash applicator is used to evenly coat the surface of the mooncake.
[0003] The existing egg wash applicator continuously transports mooncakes via a conveyor belt and uses an electric slide rail and electric push rod assembly to drive a brush to pick up and apply egg wash. However, existing egg wash applicators make it inconvenient to clean the brushes promptly after use, which can easily lead to the egg wash solidifying on the brushes, increasing the difficulty of cleaning. Furthermore, it is difficult to use the brush to pick up egg wash when the container is low. Therefore, this paper proposes an egg wash applicator for mooncake production to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an egg wash applicator for mooncake production, in order to solve the problems mentioned in the background art, such as the inconvenience of timely cleaning of the brush after use, which easily leads to the solidification of egg wash on the brush, thus increasing the difficulty of cleaning the brush, and the inconvenience of using the brush to pick up the egg wash when there is little egg wash in the container.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an egg wash applicator for mooncake production, comprising a support frame, wherein a first motor is disposed inside the support frame, and one end of the output shaft of the first motor is connected to a drive wheel via a coupling; a driven wheel is correspondingly inserted between the support frame and one side of the drive wheel; a conveyor belt is fitted around the outer wall of the drive wheel and the driven wheel; a tray is placed on the upper surface of the conveyor belt, and mooncakes are placed in the tray; a fixed frame is provided above the support frame, and an electric slide rail is disposed inside the fixed frame; an electric drive wheel is inserted on the electric slide rail. The slider has an electric push rod below it, and a telescopic arm is provided below the electric push rod. The telescopic arm has a first fixing plate at its lower end, and a brush is provided on the lower end face of the first fixing plate. The support frame has a support plate on one side of its outer wall, and a servo motor is provided on the upper end face of the support plate. One end of the output shaft of the servo motor is connected to a first rotating shaft through a coupling. The first rotating shaft has multiple sets of connecting blocks on its outer wall. The other end of the connecting block has a connecting plate, and a liquid box is provided on the connecting plate. The liquid box has a liquid inlet pipe at one end, and a fixing rod is provided inside the liquid box.
[0006] The support frame has a second fixing plate on its upper end face, and the second fixing plate has a spray arm on its right side. The spray arm has multiple sets of nozzles evenly distributed on it, and a first water inlet pipe is provided on the spray arm. The other end of the first water inlet pipe is connected to a water source through a water pump. A cleaning tank is provided below the nozzles, and a second water inlet pipe is provided on the outer wall of the upper end of the cleaning tank, and a drain pipe is provided on the outer wall of the lower end of the cleaning tank.
[0007] The cleaning tank has multiple sets of second motors at the upper part inside, and one end of the output shaft of the second motor is connected to a second rotating shaft through a coupling. The second rotating shaft has multiple sets of blades on its outer wall.
[0008] Preferably, the conveyor belt, under the action of the first motor, forms a conveying structure through the driving wheel, the driven wheel and the support frame, and the brush, under the action of the electric push rod, forms a vertical lifting structure through the telescopic arm, the first fixed plate and the liquid box.
[0009] Preferably, the liquid container forms a rotating structure with the first support plate via a first rotating shaft under the action of a servo motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The liquid container of the egg liquid applicator for mooncake production forms a rotating structure with the first support plate through the first rotating shaft under the action of the servo motor. Thus, when there is little egg liquid in the liquid container, the servo motor can drive the liquid container to rotate, thereby concentrating the egg liquid on one side for easy brush dipping. The nozzle of the device forms a connected structure with the water source through the first water inlet pipe and the spray arm under the action of the water pump. Thus, the brush can be rinsed in time after use by the nozzle, thereby avoiding egg liquid residue on the brush from solidifying and making it inconvenient for subsequent cleaning. The blades of the device form a rotating structure in the cleaning tank through the second rotating shaft under the action of the second motor. Thus, the relatively rotating blades facilitate the initial cleaning of the brush, thereby facilitating the subsequent brush treatment. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution: an egg wash applicator for mooncake production, comprising a support frame 1, a first motor 2 internally mounted on the support frame 1, one end of the output shaft of the first motor 2 connected to a drive wheel via a coupling, a driven wheel correspondingly inserted between the drive wheel and the support frame 1 on one side, a conveyor belt 3 fitted onto the outer wall of the drive wheel and driven wheel, a tray placed on the upper surface of the conveyor belt 3, and mooncakes placed in the tray, a fixed frame mounted on the upper part of the support frame 1, and an electric slide rail 4 internally mounted on the fixed frame, with an electric slider 5 inserted on the electric slide rail 4, and the electric slider... Block 5 is equipped with an electric push rod 6 below it, and an electric push rod 6 is equipped with a telescopic arm 7 below it. The telescopic arm 7 is equipped with a first fixing plate 8 at its lower end, and the first fixing plate 8 is equipped with a brush 9 on its lower end face. It should be noted that the egg liquid spreader is equipped with a mounting frame above the conveyor belt, and the fixing frame is installed on the mounting frame to install and use the electric push rod 6 assembly. In addition, the device uses the corresponding electric slide rail 4 assembly according to the mooncake production needs. The electric slide rail 4 converts the rotational motion into linear motion through the motor and transmission mechanism to drive the electric slider 5 to perform limited sliding.
[0020] Furthermore, under the action of the first motor 2, the conveyor belt 3 forms a conveying structure through the driving wheel, the driven wheel and the support frame 1, so that the mooncakes can be continuously transported by the conveyor belt 3. Under the action of the electric push rod 6, the brush 9 forms a vertical lifting structure through the telescopic arm 7, the first fixed plate 8 and the liquid box 13, so that the brush 9 can be driven to lift and lower by the electric push rod 6 assembly, so as to dip, apply and clean the brush 9 with egg liquid.
[0021] The support frame 1 has a support plate 10 on one outer wall, and the support plate 10 has a servo motor 11 on its upper surface. One end of the output shaft of the servo motor 11 is connected to the first rotating shaft 12 through a coupling. The first rotating shaft 12 has multiple sets of connecting blocks on its outer wall. The other end of the connecting blocks has a connecting plate, and the connecting plate has a liquid box 13. The liquid box 13 has a liquid inlet pipe at one end, and a fixing rod 14 inside the liquid box 13.
[0022] Furthermore, under the action of the servo motor 11, the liquid container 13 forms a rotating structure with the first support plate 10 through the first rotating shaft 12, thereby concentrating the egg liquid on one side through the rotatable liquid container 13, which makes it easier for the brush 9 to dip the egg liquid.
[0023] The support frame 1 has a second fixing plate 15 on its upper end face, and the second fixing plate 15 has a spray arm 16 on its right side. Multiple sets of nozzles 17 are evenly arranged on the spray arm 16, and a first water inlet pipe is provided on the spray arm 16. The other end of the first water inlet pipe is connected to the water source through a water pump. A cleaning tank 18 is provided below the nozzles 17, and a second water inlet pipe is provided on the outer wall of the upper end of the cleaning tank 18, and a drain pipe is provided on the outer wall of the lower end of the cleaning tank 18.
[0024] Furthermore, under the action of the water pump, the nozzle 17 forms a communication structure with the water source through the first water inlet pipe and the spray arm 16, so that the brush 9 can be rinsed in time after use through the nozzle 17, thereby avoiding egg liquid residue on the brush 9 and increasing the difficulty of subsequent cleaning.
[0025] The cleaning tank 18 has multiple sets of second motors 19 located at its upper interior. One end of the output shaft of the second motor 19 is connected to the second rotating shaft 20 via a coupling. The second rotating shaft 20 has multiple sets of blades 21 on its outer wall. It should be noted that multiple sets of electrical equipment in this device are connected to power supply equipment via power lines, and the working status of the electrical equipment is monitored by corresponding sensors, controllers and other equipment to ensure that the electrical equipment in this device can perform normal control operations.
[0026] Furthermore, under the action of the second motor 19, the blades 21 form a rotating structure in the cleaning tank 18 via the second rotating shaft 20, thereby driving the two sets of blades 21 to rotate relative to each other via the second motor 19, so that the brush 9 can be initially cleaned by the rotating blades 21.
[0027] Working Principle: When using the egg wash applicator for mooncake production, mooncakes are first neatly arranged in a tray, which is then placed on conveyor belt 3. The first motor 2 is then started. The output shaft of the first motor 2 drives the drive wheel to rotate via a coupling, which in turn drives the conveyor belt 3 via the driven wheel, allowing continuous feeding of mooncakes. Simultaneously, the electric slide rail 4 is activated. The electric slide rail 4 drives the brush 9 assembly to move horizontally via an electric slider 5, and drives the telescopic arm 7 to extend and retract via an electric push rod 6. This telescopic arm 7 then raises and lowers the brush 9, allowing it to pick up the egg wash from the liquid container 13. After picking up the egg wash, excess egg wash on the brush 9 can be scraped off via a fixing rod 14. Then, the electric slide rail 4 and electric push rod 6 allow the brush 9 to apply egg wash to the surface of the mooncakes. During the egg wash application process, the servo motor 11 can be activated. The output shaft of the servo motor 11 is connected via a coupling... The device drives the first rotating shaft 12 to rotate, which in turn drives the liquid container 13 to rotate. When there is a small amount of egg liquid, the tilted liquid container 13 can concentrate the egg liquid on one side, making it easier for the brush 9 to pick it up. After the egg liquid is applied to the mooncake, the first water inlet pipe drives the spray head 17 to work, so that the brush 9 can be rinsed in time in the cleaning tank 18. At the same time, hot water can be introduced into the cleaning tank 18 through the second water inlet pipe, and the electric push rod 6 can immerse the brush 9 into the cleaning tank 18, so as to avoid the egg liquid from solidifying on the brush 9 and affecting the subsequent cleaning efficiency. During the initial cleaning of the brush 9, the second motor 19 can be started. The output shaft of the second motor 19 drives the second rotating shaft 20 to rotate through the coupling, so that the relatively rotating blades 21 can further clean the brush 9, thereby increasing the convenience of subsequent cleaning of the brush 9. This is the usage process of the egg liquid applicator used for mooncake production.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
