[0031] Furthermore, a metering mechanism 2 is provided above the mixing barrel 11, and the metering mechanism 2 includes a mounting plate 21, the bottom of the mounting plate 21 is fixedly connected to the top of the mixing barrel 11 by bolts, and an electronic scale 22 is symmetrically fixedly connected by bolts near the left and right sides of the top of the mounting plate 21, which is used to weigh the weight of the raw materials in the metering box 23, and a metering box 23 is provided on the top of the electronic scale 22.

[0032] It should be supplemented that a connecting pipe 24 is fixedly connected to the bottom of the inner wall of the metering box 23 by bolts, and the bottom end of the connecting pipe 24 passes through the bottom of the metering box 23, the bottom of the mounting plate 21 and the top of the mixing barrel 11 corresponding to its position in sequence and passes into the inner cavity of the mixing barrel 11. A discharge valve 25 is installed on the connecting pipe 24 to control whether the raw materials can pass through the connecting pipe 24.

[0033] As a preferred embodiment of the present invention, a mixing mechanism 3 is provided above the base 1 , and the mixing mechanism 3 includes a driving motor 31 , and the driving motor 31 is fixedly connected to the top of the base 1 by bolts to drive the cam plate 32 to rotate.

[0034] Specifically, the output shaft of the driving motor 31 is coaxially connected with the cam plate 32 to drive the connecting rod 33 to move. The top of the cam plate 32 near the right side is rotatably connected with the connecting rod 33 through a bearing to drive the mounting frame 34 to move.

[0035] Specifically, the top of the connecting rod 33 near the right side is rotatably connected to a mounting bracket 34 through a bearing to drive the stirring motor 35 to move, and the top of the mounting bracket 34 is fixedly connected to the stirring motor 35 through bolts to drive the mounting rod 36 to rotate.

[0037] Specifically, a plurality of stirring rods 37 are symmetrically fixedly connected to the upper and lower sides of the circumferential outer wall of the mounting rod 36 by bolts, and the stirring rods 37 are evenly arranged at equal intervals for stirring the raw materials.

[0038] Specifically, arc scrapers 38 are symmetrically provided on the upper and lower sides of the mounting rod 36. The inner surface of the arc scraper 38 and one end of the stirring rod 37 corresponding to its position are fixedly connected by bolts. The outer surface of the arc scraper 38 is in contact with the inner wall of the circumference of the mixing barrel 11, so as to scrape off the raw materials adhering to the inner wall of the circumference of the mixing barrel 11.

[0039] It is worth noting that the structure and working principle of the electronic scale 22 involved in this embodiment are well known to those skilled in the art and will not be elaborated herein.

[0040] During the specific use process, the user first pours the two raw materials into the two measuring boxes 23 respectively, and then checks the weight of the raw materials in the two measuring boxes 23 displayed on the screens of the two electronic scales 22 until the weight displayed on one of the electronic scales 22 reaches the specified weight, and then stops pouring the raw materials into the measuring box 23 corresponding to the position of the electronic scale 22;

The stirring motor 35 drives the mounting rod 36 to rotate, thereby driving all the stirring rods 37 to rotate and stir the raw materials. In this process, the two arc-shaped scrapers 38 rotate and scrape off the raw materials adhering to the inner wall of the circumference of the mixing barrel 11;

[0042] Turn on the driving motor 31, and the driving motor 31 drives the cam plate 32 to rotate, so that the protruding end of the cam plate 32 rotates to the left, thereby driving the connecting rod 33 to move to the left, thereby driving the mounting frame 34 to move to the left. When the protruding end of the designated cam plate 32 rotates to the leftmost, the protruding end of the cam plate 32 starts to rotate to the right, thereby driving the connecting rod 33 to move to the right, thereby driving the mounting frame 34 to move to the right;

[0043] During this process, the mounting frame 34 makes left-right reciprocating motion, thereby driving the stirring motor 35 to make left-right reciprocating motion, thereby driving the mounting rod 36 to make left-right linear reciprocating motion during the rotation, thereby driving all stirring rods 37 to make left-right linear reciprocating motion during the stirring of the raw materials, until the raw materials are stirred evenly, turn off the drive motor 31 and the stirring motor 35, turn on the feeding pump 14, and the feeding pump 14 sucks out the raw materials in the mixing barrel 11 through the feed pipe 15 and transmits the raw materials to the transmission channel connected to the left end of the transmission pipe 16 through the transmission pipe 16.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
