Description

Technical Field

[0001] The utility model belongs to the technical field of grinding mills, and particularly relates to a non-drifting automatic weighing mechanism of a grinding mill. Background Art

[0002] In the process of processing some powder materials, a grinding mill is usually used for processing. The grinding mill grinds the material into powder and discharges it through a discharge pipe. In order to increase the accuracy of the quality of each portion of powder, companies usually use automatic weighing mechanisms to complete weight detection. In order to ensure that the weighing data is not affected by temperature drift, temperature compensation technology is generally used, such as a built-in temperature sensor, to correct the weighing results according to temperature changes to ensure the accuracy of the weighing results in different temperature environments.

[0003] However, in the discharge process of the grinding mill, there is a problem that has long plagued the industry. When the existing discharge pipe puts the powder into the container, the container opening is usually large to accommodate different production scales and material characteristics. As a result, the powder material is prone to smoke-like diffusion and sputtering during the discharge process. On the one hand, these drifting smoke-like powders will permeate the air in the production workshop, causing serious air pollution, which not only affects the health of the operators, but also pollutes and damages other equipment and electrical lines in the workshop, increasing equipment maintenance costs and safety risks. On the other hand, the sputtered powder is directly scattered on the ground and workbench around the container, causing waste of materials and increasing the company's production costs. Moreover, it requires extra manpower and time costs for cleaning, further affecting production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 5 The utility model provides the following technical solutions: it includes a discharge pipe 1 and a discharge valve 11, a vertical support plate 2 is provided on one side of the discharge pipe 1, the discharge pipe 1 passes through the side wall of the vertical support plate 2, a lifting support plate 21 is slidably connected to one side of the vertical support plate 2, the bottom of the lifting support plate 21 is rotatably connected to a rotating bracket 3, a plurality of weighing cylinders 4 are provided on the outside of the rotating bracket 3, and the plurality of weighing cylinders 4 are aligned with the bottom of the discharge valve 11 in sequence, a weighing plate 41 for weighing the powder is installed on the bottom of the inner side of the weighing cylinder 4, a sliding rod 42 is slidably connected to the inner wall of the weighing cylinder 4, and a blocking ball 421 is installed on the top of the sliding rod 42, and the blocking ball 421 is consistent in size with the top opening of the weighing cylinder 4.

[0019] The lifting plate 21 is used to lift the material handling equipment 1 and the lifting plate 22, so that the material handling equipment 1 can be lifted up and the material handling equipment 1 can be lifted up. The powder is closed, so that the powder can be limited and blocked by the discharge pipe 1 and the weighing cylinder 4 when it is put downward. The powder uses its own gravity to press the weighing plate 41 downward, so that the weighing sensor on the weighing plate 41 can measure the mass of the powder and complete the weighing. The discharge valve 11 blocks the passage of the discharge pipe 1, so that the powder will no longer be put in when the quality reaches the specification. After the filling and weighing are completed, the control sliding rod 42 pushes the blocking ball 421 upward, so that the blocking ball 421 can enter the caliber at the top of the weighing cylinder 4 to complete the blocking, so that the weighing cylinder 4 can still ensure the stability of the powder during the transfer process, prevent external contamination and leakage, thereby solving the problem that the powder is easy to scatter and splash. The scattered smoke-like powder will permeate the air in the production workshop, causing serious air pollution, which not only affects the health of the operators, but also pollutes and damages other equipment and electrical lines in the workshop, and causes waste of materials and cleaning costs, increasing the production cost of the enterprise.

[0020] The bottom end of the lifting support plate 21 is rotatably connected to the driving rod 22, and the top of the lifting support plate 21 is installed with a driving mechanism 23. The output end of the driving mechanism 23 is installed at the top of the driving rod 22, and the rotating bracket 3 is installed at the bottom end of the vertical support plate 2; the lifting support plate 21 supports the rotating bracket 3 through the driving rod 22, and the driving mechanism 23 is a motor. The driving mechanism 23 drives the driving rod 22 to rotate, so that the rotating bracket 3 can drive several weighing cylinders 4 to rotate, thereby realizing the switching use of the weighing cylinders 4 and improving work efficiency.

[0021] A rotating connection mechanism 31 is provided between the rotating bracket 3 and several weighing cylinders 4. The rotating connection mechanism 31 is installed on one side of the corresponding weighing cylinder 4, and several rotating connection mechanisms 31 are rotatably connected to one end of the rotating bracket 3; the rotating bracket 3 supports the weighing cylinder 4 through the rotating connection mechanism 31, and a motor for adjusting its own angle is provided in the rotating connection mechanism 31. When the weighing cylinder 4 is loaded with powder and transferred to the next workstation, the weighing cylinder 4 is driven to rotate by controlling the rotating connection mechanism 31, so that the opening of the weighing cylinder 4 can face the material receiving unit, thereby completing the discharge of the powder, reducing the impact on the operation of the discharge pipe 1, and further improving work efficiency.

[0022] A connecting disk 43 is installed at the bottom end of the sliding rod 42, and a telescopic adjusting rod 44 is installed at the bottom of the connecting disk 43. The output end of the telescopic adjusting rod 44 passes through the top of the connecting disk 43, and the output end of the telescopic adjusting rod 44 is installed at the bottom of the corresponding weighing cylinder 4; the position of the end of the telescopic adjusting rod 44 is always consistent with that of the weighing cylinder 4, so that the weighing cylinder 4 can drive the connecting disk 43 to move closer to or further away from the weighing cylinder 4. When the connecting disk 43 approaches the direction of the weighing cylinder 4, the connecting disk 43 can push the sliding rod 42 to slide toward the opening direction of the weighing cylinder 4, so that the blocking ball 421 can complete the work of blocking the opening of the weighing cylinder 4.

[0023] An inner bevel 45 is provided on the inner side of the top of several weighing cylinders 4, and an outer bevel 12 corresponding to the shape of the inner bevel 45 is provided at the bottom of the discharge pipe 1. The discharge pipe 1 and the weighing cylinder 4 are connected by the outer bevel 12 and the inner bevel 45; when the weighing cylinder 4 and the discharge pipe 1 are docked, the outer bevel 12 is engaged into the inner bevel 45, which facilitates the docking of the weighing cylinder 4 and the discharge pipe 1, and increases the connection range between the weighing cylinder 4 and the discharge pipe 1, improves the sealing effect, and at the same time plays a role of mutual limitation to prevent shaking.

[0024] The working principle and use process of the present invention are as follows: after the grinding mill processes the powder, the grinding mill puts the powder into the discharge pipe 1 for weighing. After the weighing cylinder 4 is aligned with the bottom of the discharge pipe 1, the lifting support plate 21 is lifted upward so that the weighing cylinder 4 can dock with the outer oblique opening 12 at the bottom of the discharge pipe 1 through the inner oblique opening 45, completing the docking of the weighing cylinder 4 and the discharge pipe 1. When the discharge valve 11 is opened, the powder is poured into the weighing cylinder 4, and the weighing sensor on the weighing plate 41 can measure the mass of the powder to complete the weighing. When the powder is put downward, it can be limited and blocked by the discharge pipe 1 and the weighing cylinder 4. This solves the problem that powder is easily scattered and splashed. The scattered smoke-like powder will permeate the air in the production workshop, causing serious air pollution, which not only affects the health of the operators, but also pollutes and damages other equipment, electrical lines, etc. in the workshop, and causes waste of materials and cleaning costs, increasing the production cost of the enterprise. After filling and weighing are completed, the telescopic adjustment rod 44 drives the blocking ball 421 to seal the opening of the weighing cylinder 4 through the connecting plate 43 and the sliding rod 42, so that the weighing cylinder 4 can still ensure the stability of the powder during the transfer process to prevent external contamination and leakage.
