It can not only improve production efficiency but also reduce energy consumption and production costs, and is an essential device in industrial production.

[0003] However, when using the existing rotor scale to weigh powdery materials, since the powdery materials inside are prone to getting damp and caking, it will affect the flow and measurement accuracy of the powdery materials; in addition, if the humidity of the powdery materials is relatively high, it will also lead to inaccurate measurement and even block the equipment, thus affecting the normal progress of production.

[0028] Referring to Figures 1-4 , a multi-layer rotor scale provided by an embodiment of the present utility model will now be described. A multi-layer rotor scale includes a bottom plate 1. A support rod 2 is fixedly connected to the top of the bottom plate 1. There are a plurality of support rods 2 distributed in a ring. A housing 3 is fixedly connected to the top of the support rod 2. A drive motor 4 is fixedly installed at the bottom of the housing 3. An output end of the drive motor 4 is fixedly installed with a rotating shaft 5. The rotating shaft 5 is movably installed inside the housing 3. A feed pipe 6 is fixedly connected to the outer wall of the housing 3. A discharge pipe 7 is fixedly connected to the bottom of the housing 3. A crushing assembly 8 is installed inside the housing 3. A weighing assembly 9 is installed inside the housing 3; the crushing assembly 8 includes a turntable 801, a first grinding block 802, and a second grinding block 803. The turntable 801 is fixedly connected to the outer wall of the rotating shaft 5. There are a plurality of first grinding blocks 802 fixedly connected to the outer wall of the turntable 801 in a ring. There are a plurality of second grinding blocks 803 distributed in a ring on the inner wall of the housing 3. The first grinding block 802 and the second grinding block 803 are meshed with each other.

[0029] After adding the powdery material into the housing 3 through the feed pipe 6, the drive motor 4 is started. The output end of the drive motor 4 drives the rotating shaft 5 to rotate, thereby driving the turntable 801 fixedly connected to the outer wall of the rotating shaft 5 to rotate, and further driving the plurality of first grinding blocks 802 fixedly connected to the turntable 801 in a ring to rotate. Since the plurality of first grinding blocks 802 mesh with the plurality of second grinding blocks 803 distributed in a ring on the inner wall of the housing 3, when the powdery material passes between the first grinding block 802 and the second grinding block 803, the caked powdery material can be squeezed and ground to be broken.

[0030] A funnel 804 is fixedly connected to the inner wall of the housing 3. The funnel 804 is located at the bottom of the turntable 801. A discharge port 805 is fixedly connected to the bottom of the funnel 804.

[0031] After being crushed, the powdered material falls into the funnel 804 under the action of gravity, and then is discharged through the discharge port 805 at the bottom of the funnel 804, ensuring that the powdered material can smoothly enter the next process and enhancing the stability of the powdered material transportation.

[0032] The weighing assembly 9 includes a connecting rod 901 and a pushing plate 902. There are multiple connecting rods 901 installed on the outer wall of the rotating shaft 5 in a circular bolt pattern. The connecting rod 901 is located at the bottom of the funnel 804. The pushing plate 902 is fixedly connected to one end of the connecting rod 901 away from the pushing plate 902. The front end of the outer wall of the pushing plate 902 is in contact with the inner wall of the housing 3.

[0033] When the powdered material enters the inner bottom of the housing 3 through the discharge port 805, the rotating shaft 5 drives the connecting rod 901 and the pushing plate 902 to rotate. During the rotation of the pushing plate 902, it pushes the powdered material to move, and pushes the powdered material towards the discharge pipe 7 to be discharged. During the movement of the powdered material, by using the principle of a rotor scale, parameters such as the force exerted by the powdered material on the pushing plate 902 and the rotation speed of the rotating shaft 5 are measured, and the flow rate and weight of the powdered material are calculated to ensure the accurate feeding of the powdered material during the production process, thereby improving the product quality.

[0034] The inner wall of the housing 3 is fixedly connected with an annular baffle 903. There are two annular baffles 903 distributed up and down. The connecting rod 901 is located between the two annular baffles 903. The rear end of the outer wall of the pushing plate 902 is in contact with the outer wall of the pushing plate 902.

[0035] The annular baffle 903 plays a role in limiting the powdered material, preventing the powdered material from spreading to both sides during the process of the pushing plate 902 pushing the powdered material, and ensuring that the powdered material can be accurately pushed towards the discharge pipe 7.

[0036] A fan 10 is fixedly installed at the top of the rotating shaft 5. The fan 10 is located at the top of the fan 10. The feed pipe 6 is located between the fan 10 and the crushing assembly 8.

[0037] When the rotating shaft 5 rotates, it drives the fan 10 to rotate to generate an air flow. The air flow can reduce the humidity of the powdered material, prevent the powdered material from caking due to excessive humidity, and at the same time helps the flow of the powdered material.

[0038] The top of the housing 3 is provided with air inlet grooves 301, and the number of air inlet grooves 301 is multiple.

[0039] The air flow can enter the interior of the housing 3 through the air inlet grooves 301.

[0040] A support seat 101 is fixedly connected to the top of the bottom plate 1. The bottom of the driving motor 4 is fixedly installed on the top of the support seat 101.

[0041] The support base 101 is used to provide stable support for the driving motor 4, reduce the vibration of the driving motor 4 during operation, and ensure the normal operation of the present utility model.

[0042] The bottom of the bottom plate 1 is fixedly installed with universal wheels 11, and there are multiple universal wheels 11 distributed in a ring.

[0043] By providing the universal wheels 11, it is convenient to move the present utility model to a designated position according to the production environment and actual needs.

[0044] Working principle: First, after adding the powdery material into the interior of the outer shell 3 through the feed pipe 6, the driving motor 4 operates. The output end of the driving motor 4 drives the rotating shaft 5 to rotate, thereby driving the turntable 801 fixed on the outer wall of the rotating shaft 5 to rotate. Since the first grinding block 802 on the turntable 801 meshes with the second grinding block 803 on the inner wall of the outer shell 3, the caked powdery material can be crushed. The crushed powdery material falls into the funnel 804 under the action of gravity and is discharged through the discharge port 805 at the bottom of the funnel 804.

[0045] After the powdery material enters the inner bottom of the outer shell 3 through the discharge port 805, the rotating shaft 5 drives the connecting rod 901 and the pushing plate 902 to rotate. During the rotation process, the pushing plate 902 pushes the powdery material to move and pushes the powdery material towards the discharge pipe 7 for discharge. In this process, using the principle of a rotor scale, by measuring parameters such as the force exerted by the powdery material on the pushing plate 902 and the rotational speed of the rotating shaft 5, the flow rate and weight of the powdery material are calculated, thereby achieving accurate weighing.

[0046] At the same time, the fan 10 at the top of the rotating shaft 5 rotates with the rotating shaft 5 to generate an air flow. The air flow enters the interior of the outer shell 3 through the air inlet groove 301 at the top of the outer shell 3, which can reduce the humidity of the powdery material, prevent the powdery material from caking due to excessive humidity, and contribute to the flow of the powdery material.

[0047] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
