An oil tank is fixedly installed on the top of the square frame. A threaded cap is threadedly connected to the top of the oil tank. A clamping block is held on the outer edge of the oil tank.

[0006] As a preferred technical solution of this utility model: the second gear meshes with the conveyor belt, the second sprocket meshes with the chain, and the fourth gear meshes with the toothed belt.

[0007] As a preferred technical solution of this utility model: the top of the rotating block is rotatably connected to the bottom of the block, and there are two sets of sprockets and support rods. The first set of support rods is fixedly installed with the movable frame, and the second set of sprockets and support rods is located at the end away from sprocket one.

[0008] As a preferred technical solution of this utility model: the bottom of the support frame is fixedly equipped with support legs, and the number of support legs is four sets; a food placement rack is placed on the top of the conveyor belt; and a conical oil drip nozzle is fixedly installed on the bottom of the oil tank.

[0009] As a preferred technical solution of this utility model: a controller is fixedly installed on the outside of the support block, and the first motor, the second motor, the third motor and the electric push rod are all electrically connected to the controller. There are three electric push rods, which are located on the inner wall of the three rotating blocks. The brush plate is slidably connected to the inner wall of the rotating block.

[0010] As a preferred technical solution of this utility model: there are two gears, one gear and two gears, and an egg liquid frame and an egg liquid collection plate are fixedly installed on the top of the support frame, and a serrated blocking plate is provided above the egg liquid collection plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This rotary egg brushing machine with adjustable brush length, through the combined use of clamping blocks and an oil tank, addresses the issue of rust appearing on the chain after prolonged use, affecting the normal operation of the moving frame, blocks, and rotating blocks. The user can open the threaded cap and inject oil into the inner wall of the oil tank. The clamping blocks, held by the outer edge of the oil tank, compress the opening, reducing the angle and causing the lubricating oil to drip onto the chain surface through the conical drip nozzle at the bottom of the oil tank. This lubricates and removes rust from the chain, extending its service life and maintaining the device's efficiency.

[0013] 2. This rotary egg brushing machine with adjustable brush length uses an electric push rod and a third motor in conjunction. The controller then operates the third motor, whose power output shaft drives a third gear to rotate. This gear drives a toothed belt, and the rotation of the belt, along with the meshing of the fourth gear and the belt, causes two rotating rods to rotate together. This, in turn, rotates the rotating block, causing the electric push rod and brush plate located on the inner wall of the rotating block to rotate at high speed. This achieves the purpose of high-speed coating of egg wash onto mooncakes or pastries. Simultaneously, by controlling the electric push rod through the rotating block, the brush plate can be lowered along the inner wall of the rotating block, making its length adjustable. This increases the contact area between the brush plate and mooncakes / pastries, resulting in more comprehensive coating and improved efficiency. It also avoids the problem of smaller items not being coated. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-6 A rotary egg brushing machine with adjustable brush length includes a support frame 1. A motor 2 is fixedly mounted on the outer side of the support frame 1. A gear 3 is fixedly mounted on the power output shaft of the motor 2. A conveyor belt 4 meshes with the outer edge of the gear 3. A round rod 5 is fixedly mounted on the inner wall of the support frame 1. A gear 6 is rotatably connected to the outer edge of the round rod 5. A support block 11 is fixedly mounted on the top of the support frame 1. A square frame 12 is fixedly mounted on the top of the support block 11. A motor 13 is fixedly mounted on the outer side of the square frame 12. A sprocket 14 is fixedly mounted on the power output shaft of the motor 13. A chain 15 meshes with the outer edge of the sprocket 14. A support rod 17 is slidably connected to the inner wall of the square frame 12. A sprocket 16 is fixedly mounted on the outer edge of the support rod 17. A movable frame 18 is slidably connected to the outside of frame 12. A block 19 is fixedly installed at the bottom of the movable frame 18. A motor 20 is fixedly installed at the top of the block 19. A gear 21 is fixedly installed on the power output shaft of the motor 20. A toothed belt 22 meshes with the outer edge of the gear 21. A rotating rod 23 is rotatably connected to the inner wall of the block 19. A gear 24 is fixedly installed on the outer edge of the rotating rod 23. A rotating block 31 is fixedly installed on the outer edge of the rotating rod 23. An electric push rod 25 is fixedly installed on the inner wall of the rotating block 31. A brush plate 26 is fixedly installed at the extended end of the electric push rod 25. An oil tank 27 is fixedly installed at the top of the frame 12. A threaded cap 28 is threadedly connected to the top of the oil tank 27. A clamping block 29 is held on the outer edge of the oil tank 27.

[0023] In the above structure, through the cooperation of clamping block 29 and oil tank 27, when the chain 15 develops rust after prolonged use, affecting the normal operation of the movable frame 18, block 19, and rotating block 31, the user can unscrew the threaded cover 28 and inject oil into the inner wall of the oil tank 27. Then, by squeezing the opening of clamping block 29 held by the outer edge of oil tank 27, the opening angle of clamping block 29 is reduced, causing the lubricating oil in oil tank 27 to drip onto the surface of chain 15 through the conical oil drip nozzle 32 at the bottom of oil tank 27. This achieves the purpose of lubricating and removing rust from chain 15, extending the actual service life of chain 15, and ensuring that the efficiency of the device is not reduced.

[0024] In a preferred embodiment: gear 2 6 meshes with conveyor belt 4, sprocket 2 16 meshes with chain 15, and gear 4 24 meshes with toothed belt 22.

[0025] In the above structure, the meshing between gear 26 and conveyor belt 4, sprocket 216 and chain 15, and gear 424 and toothed belt 22 causes the power output shaft of motor 2 to drive gear 3 to rotate, which in turn drives gear 26 to rotate. This allows conveyor belt 4 to stably move the food rack 33 at the top of conveyor belt 4. Furthermore, the meshing between sprocket 216 and chain 15 allows chain 15 to smoothly drive sprocket 216 to mesh and rotate within chain 15, thereby driving the moving parts... Frame 18, block 19, and rotating block 31 move normally on the outer wall of frame 12. Then, through the meshing between gear 4 24 and toothed belt 22, when the power output shaft of motor 3 20 drives gear 3 21 to rotate, gear 3 21 drives toothed belt 22 to rotate. The rotation of toothed belt 22 enables gear 4 24 and the power output shaft of motor 3 20 to smoothly drive rotating block 31 to rotate, so that the electric push rod 25 and brush plate 26 located on the inner wall of rotating block 31 rotate together at high speed, thereby achieving the purpose of high-speed coating of egg liquid on mooncakes or pastries.

[0026] In a preferred embodiment: the top of the rotating block 31 is rotatably connected to the bottom of the block 19, and there are two sets of sprockets 16 and support rods 17. The first set of support rods 17 is fixedly installed with the movable frame 18, and the second set of sprockets 16 and support rods 17 is located at the end away from sprocket 14.

[0027] In the above structure, the second set of sprockets 16 and support rods 17 are used to enable the chain 15 to rotate stably, while the first set of sprockets 16 and support rods 17 can drive the movable frame 18, block 19 and rotating block 31 to slide back and forth smoothly on the outside of the frame 12.

[0028] In a preferred embodiment: support legs 10 are fixedly installed at the bottom of the support frame 1, and the number of support legs 10 is four sets; a food placement rack 33 is placed on the top of the conveyor belt 4; and a conical oil drip nozzle 32 is fixedly installed at the bottom of the oil tank 27.

[0029] In the above structure, the four sets of support legs 10 enable the device to operate stably.

[0030] In a preferred embodiment: a controller 30 is fixedly installed on the outside of the support block 11. Motor 1 2, motor 2 13, motor 3 20 and electric push rod 25 are all electrically connected to the controller 30. There are three electric push rods 25, which are located on the inner wall of the three rotating blocks 31. The brush plate 26 is slidably connected to the inner wall of the rotating block 31.

[0031] In the above structure, the controller 30 is electrically connected to the first motor 2, the second motor 13, the third motor 20, and the electric push rod 25, so that the controller 30 can start or stop the first motor 2, the second motor 13, the third motor 20, and the electric push rod 25.

[0032] In a preferred embodiment: there are two gears 3 and two gears 6. An egg liquid frame 7 and an egg liquid collection plate 8 are fixedly installed on the top of the support frame 1. A serrated baffle plate 9 is provided above the egg liquid collection plate 8.

[0033] In the above structure, the serrated baffle plate 9 can separate the excess egg liquid adhering to the brush plate 26, thus avoiding waste of egg liquid during the application process.

[0034] Working Principle: When this device is needed, it is first used in conjunction with the clamping block 29 and the oil tank 27. When the chain 15 develops rust after prolonged use, affecting the normal operation of the movable frame 18, block 19, and rotating block 31, the user can unscrew the threaded cap 28 and inject oil into the inner wall of the oil tank 27. Then, the clamping block 29, held by the outer edge of the oil tank 27, is used to squeeze the opening of the clamping block 29, reducing the angle at the opening. This causes the lubricating oil in the oil tank 27 to drip onto the surface of the chain 15 through the conical drip nozzle 32 at the bottom of the oil tank 27, thus achieving the purpose of lubricating and removing rust from the chain 15, extending its service life, and ensuring the device's efficiency is not reduced. Secondly, the serrated baffle plate 9 separates excess egg wash from the brush plate 26, preventing waste during egg wash application. By utilizing the combined use of electric push rod 25 and motor 20, the controller 30 controls motor 20 to operate. The power output shaft of motor 20 drives gear 21 to rotate, which in turn drives toothed belt 22. Through the transmission of toothed belt 22 and the meshing of gear 24 with toothed belt 22, two rotating rods 23 rotate together, thereby driving rotating block 31 to rotate. This causes electric push rod 25 and brush plate 26 located on the inner wall of rotating block 31 to rotate at high speed, achieving the purpose of high-speed coating of egg wash on mooncakes or pastries. Simultaneously, by controlling electric push rod 25 to operate through rotating block 31, brush plate 26 can be lowered on the inner wall of rotating block 31. The length of brush plate 26 is adjustable, resulting in a larger contact area between brush plate 26 and mooncakes or pastries, which has the advantages of more comprehensive coating and improved coating efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
