At present, many mechanical parts and some commonly used powder or granular materials for daily necessities are used as the main raw materials and further processed into shapes. In the process of reproduction, the main raw materials often need to be weighed quantitatively and mixed and stirred if necessary. Generally speaking, in the production process, automatic weighing machines will be used for automatic weighing. The automatic weighing machine uses screws to rotate and unload, making screws the most commonly inspected and maintained component. The traditional method of fixing screws on automatic weighing machines is through bolts, which is cumbersome to disassemble and time-consuming.

Automatic material weighing machine

1. Research and development content and objectives:

The screw disassembly mechanism of the automatic weighing machine developed in this project includes a bracket and a coupling; The screw is fixed inside the bracket, and the screw and motor are driven through a coupling; One side of the motor and one side of the bracket are hinged, and the other side of the motor and the other side of the bracket are fixed by bolts.

The screw disassembly mechanism of the automatic weighing machine is hinged on one side of the motor and the bracket, and fixed on the other side of the motor and the bracket with bolts and bolts. When you want to disassemble, simply remove the bolts to disassemble the motor and screws for maintenance.

2. Technological innovation points:

1. The bracket adopts a card slot design, with the axial direction set inside the card slot. The bearing sleeve screws have a simple structure and strong stability;

2. The axial design of the card slot adopts a card structure, with a protrusion on the card to embed into the motor, better fixing the motor and effectively ensuring stable operation, less vibration, and strong stability of the motor;

3. Adopting dynamic and fixed bracket designs, the dynamic bracket is fixed to the fixed bracket by bolts; The bolt fixing holes of the fixed bracket are long sliding holes, which can adjust the fixing position of the dynamic bracket, with strong flexibility and easy operation and adjustment.

3. Main technical indicators of economic indicators:

1. Structure: including bracket and coupling;

2. Power supply: 220AC;

3. Screw and motor transmission method: coupling;

4. Connection method between motor and bracket: hinged and bolted;

5. Card structure: raised design;

6. Number of couplings: 2;

7. Number of shelves: 2.

Economic and social benefits and application prospects.

This project is being improved and refined based on current practical issues, especially the feedback from the on-site market. Abandoning the shortcomings of past structural design and technology, redesigning and developing to meet the rapid development of current society and industry, and achieving the goal of high quality, efficiency, and low cost;

This project adopts a long screw structure that can be quickly disassembled. Through the development of this project, the disassembly efficiency of the testing machine has been improved by over 47%, production efficiency has also been enhanced, stability has been improved, and weighing has been more accurate.
