[0022] ​Firstly, the raw materials to be stirred are poured into the interior of the stirring kettle 2, and then the motor 3 is started, and the motor 3 rotates to drive the stirring rod 4 to rotate, and the stirring rod 4 strikes the raw materials in the interior of the stirring kettle 2 to mix the raw materials, when the stirring is completed, the electronic valve is opened, and the raw materials in the interior of the stirring kettle 2 fall freely under the action of gravity, and then the electronic valve is controlled to be closed and then opened again, so that the function of quantitative intermittent discharging is achieved, however, in order to achieve the function of quantitative intermittent discharging, the electronic valve needs to be frequently started and stopped, which undoubtedly reduces the service life of the electronic valve and improves the service life of the device, in the use of the utility model, the rubber baffle 6 is used instead of the electronic valve, the rubber baffle 6 is made of rubber material and has good sealing performance, when the stirring is completed, the rubber baffle 6 is moved by the power mechanism, and when the rubber baffle 6 moves, the fixed plate 7 moves along the outside of the limiting rod 8, the fixed plate 7 presses the spring 10 at this time, the spring 10 is deformed and generates elastic potential energy, and when the rubber baffle 6 moves, the rubber baffle 6 stops blocking the bottom end of the stirring kettle 2, and the raw materials in the interior of the stirring kettle 2 can fall, along with the continuous operation of the power mechanism, the power mechanism stops dragging the rubber baffle 6, the spring 10 stops being stressed at this time, and releases the elastic potential energy, the rubber baffle 6 is reset by the fixed plate 7, at this time, the rubber baffle 6 blocks the bottom end of the stirring kettle 2 again, and the internal raw materials cannot be discharged, and after the power mechanism operates for a period of time, the rubber baffle 6 is moved again, and the above-mentioned action is repeated, so that the function of quantitative intermittent discharging is achieved.

[0023] As shown in Figure 3 The power mechanism comprises a motor 11, a half gear 12 and a rack 13, the half gear 12 is fixedly connected with the outside of the output end of the motor 11, the rack 13 is engaged with the half gear 12, and the rack 13 is fixedly connected with the bottom end of the rubber baffle 6.

[0024] When the motor 11 is started, the motor 11 rotates, and the half gear 12 rotates, and since the half gear 12 is in the engaged state with the rack 13, the half gear 12 drives the rack 13 to move, and the movement of the rack 13 drives the rubber baffle 6 to move, along with the rotation of the half gear 12 for a certain number of turns, the half gear 12 is disengaged from the rack 13, and the rubber baffle 6 is reset under the action of the spring 10, and then, since the half gear 12 continuously rotates, the half gear 12 rotates again to engage with the rack 13, so that the above-mentioned action is repeated.

[0025] As shown in Figure 3 and Figure 4As shown, the output end of the motor 11 is fixed with a three-quarter gear 14 and a quarter gear 15, the motor 11 is installed with a cylinder 16 away from the three-quarter gear 14, the output end of the cylinder 16 is fixed with the motor 11, the connecting plate 17 is fixed at the top end of the supporting plate 5.

[0026] In order to realize the adjustment of the amount of the stirring kettle 2, when the amount of the discharge needs to be increased, the cylinder 16 is started, the cylinder 16 drives the motor 11 to move towards the direction of the cylinder 16, and the movement of the motor 11 drives the three-quarter gear 14 to move, at this time, the half gear 12 is disengaged from the engagement with the rack 13, and the three-quarter gear 14 is engaged with the rack 13, because the number of gear rings of the three-quarter gear 14 is more than the number of gear rings of the half gear 12, therefore, the engagement time of the three-quarter gear 14 and the rack 13 is increased compared with the engagement time of the half gear 12 and the rack 13, at this time, the opening time of the rubber baffle 6 is also increased, and the raw materials in the stirring kettle 2 have more time to fall, thereby achieving the function of increasing the amount of the discharge, when the amount of the discharge of the stirring kettle 2 needs to be reduced, only the quarter gear 15 is engaged with the rack 13 through the cylinder 16, at this time, the movement time of the rubber baffle 6 is reduced, and the amount of the discharge is also reduced.

[0027] As shown in Figure 2 and Figure 3 As shown, the outer side of the cylinder 16 is fixed with a limiting frame 18, and the limiting frame 18 is fixed at the top end of the supporting plate 5 away from the cylinder 16.

[0028] The support of the cylinder 16 by the connecting plate 17 alone can be unstable, the limiting frame 18 is fixed on the outer side of the cylinder 16, which can strengthen the support of the cylinder 16 and effectively avoid the unstable condition of the cylinder 16 during operation.

[0029] As shown in Figure 3 The spring 10 is provided with a pair of springs 10, and the pair of springs 10 is respectively sleeved on the outer side of the pair of limiting rods 8.

[0030] Because the spring 10 is a consumable product, the service life of the spring 10 can be greatly reduced after a long time of operation, therefore, the spring 10 is installed on the outer side of the pair of limiting rods 8, so that when a group of springs 10 is damaged, another group of springs 10 can also work instead.

[0031] Working principle: the rubber baffle 6 is used instead of the electronic valve, the rubber baffle 6 is of rubber material, has good sealing property, after stirring is finished, the rubber baffle 6 is moved by the power mechanism, when the rubber baffle 6 moves, the fixed plate 7 moves along the outside of the limiting rod 8, the fixed plate 7 extrudes the spring 10, the spring 10 is deformed and generates elastic potential energy, when the rubber baffle 6 moves, the rubber baffle 6 blocks the bottom end of the stirring kettle 2, the raw materials in the stirring kettle 2 can fall, along with the continuous operation of the power mechanism, the power mechanism ends the traction of the rubber baffle 6, the spring 10 releases the elastic potential energy, the rubber baffle 6 is reset by the fixed plate 7, at this time, the rubber baffle 6 blocks the bottom end of the stirring kettle 2 again, the internal raw materials cannot be discharged, and the power mechanism operates for a period of time, then the rubber baffle 6 is moved again, the above-mentioned action is repeated, thereby the function of quantitative intermittent discharging is achieved.

[0032] When the motor 11 starts, it rotates, and the half gear 12 rotates, since it is in meshing state with the rack 13, the half gear 12 drives the rack 13 to move, and the rack 13 moves to drive the rubber baffle 6 to move, along with the rotation of the half gear 12 for a certain number of turns, the half gear 12 is disengaged from the meshing with the rack 13, and the rubber baffle 6 is reset under the action of the spring 10, and then, since the half gear 12 continues to rotate, the half gear 12 rotates to mesh with the rack 13 again, thereby the above-mentioned action is repeated.

[0033] When it is needed to increase the discharging amount, the air cylinder 16 can be started, the air cylinder 16 drives the motor 11 to move towards the air cylinder 16, the motor 11 moves to drive the three-quarter gear 14 to move, at this time, the half gear 12 is disengaged from the meshing with the rack 13, and the three-quarter gear 14 meshes with the rack 13, since the gear number of the three-quarter gear 14 is more than that of the half gear 12, therefore, the rotating meshing time of the three-quarter gear 14 with the rack 13 is increased compared with that of the half gear 12 with the rack 13, at this time, the opening time of the rubber baffle 6 is also increased, the raw materials in the stirring kettle 2 have more time to fall, thereby the function of increasing the discharging amount is achieved, when it is needed to reduce the discharging amount of the stirring kettle 2, only the one-quarter gear 15 is needed to mesh with the rack 13 by the air cylinder 16, at this time, the moving time of the rubber baffle 6 is reduced, and the discharging amount is also reduced.

[0034] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
