Specific implementation

[0026] This part will describe the specific embodiment of the utility model in detail, and the preferred embodiment of the utility model is shown in the attached drawings, and the function of the attached drawings is to supplement the description of the text part with graphics, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the utility model, but it cannot be understood as the limitation of the protection scope of the utility model.

[0027] Referring to Figures 1-4 , the utility model discloses material feeding and material distributing automatic testing device, including work platform 1, its characterized in that, the upper end of work platform 1 is fixedly connected with weighing box 7, the bottom of weighing box 7 is installed high-precision electronic scale, and the graduation value is 2g, can satisfy the use demand, and the electronic scale also has the communication function and can transmit the gram weight in real time and has the data recording function, one side of weighing box 7 is provided with suction pump 2, the other end of suction pump 2 is provided with experiment table 3, the bottom of experiment table 3 is fixedly connected with motor two 19, and gear three 20 is installed on motor two 19, and rotary table 8 is rotatably connected to the upper middle part of experiment table 3, a plurality of moulds 4 are correspondingly installed on the outer end of rotary table 8, and the moulds 4 are mutually matched, and the connecting part of motor two 19 and gear three 20 can be connected using bevel gears, so that the horizontally arranged force is converted into the longitudinal gear three 20 rotating force, and the rotating operation of rotary table 8 is completed in cooperation with pawl 21, and, in order to reach the rotating speed of 12RPM, when motor two 19 is selected, a motor with larger power and lower speed is used to meet the actual production requirement;

[0028] The rotating platform 8 has an open structure in the middle. A retaining tooth 21 is fixedly connected to the inner end of the opening of the rotating platform 8. Gear 3 20 meshes with retaining tooth 21. A bracket 6 is fixedly connected to one end of the upper part of the experimental platform 3. Gear 2 15 and a fixed seat 16 are fixedly connected to the bracket 6. A crossbeam 9 is rotatably connected to the bracket 6. A motor 13 is fixedly connected to one end of the outer side of the crossbeam 9. The output end of motor 13 passes through the crossbeam 9 and is fixedly connected to gear 14 downwards. Gear 14 meshes with gear 2 15. The rotating assembly of the upper cover 12 is rotary. The support structure is biased towards the mold 4 because the center of gravity of the upper cover 12 is located on the upper part of the mold 4, while the bracket 6 is located on one side of the mold 4. This makes the center of gravity of the entire support structure biased towards the mold 4. The general support structure cannot meet the working conditions of eccentric load. Therefore, the motor 13 drives the gear 14 to rotate. Then, under the meshing action, the gear 14 can drive the crossbeam 9 to rotate and adjust around the bracket 6. The advantage of the rotary support is that it can withstand a large eccentric load. Therefore, the use of the rotary support can solve the problem of eccentric load on the upper cover.

[0029] A cylinder 11 is fixedly connected to the end of the crossbeam 9. The extension end of the cylinder 11 is fixedly connected to the top cover 12 through and downward. The cylinder 11 can drive the top cover 12 to move downward. When the top cover 12 is pressed down, there will be a certain gap between the outer edge of the top cover 12 and the outer side of the mold 4. This gap can effectively reduce the friction between the mold 4 and the edge. The inner edge of the mold 4 is in slight contact with the inner edge. In this state, the gap between the inner edge and the inner edge of the mold 4 is very small, which can effectively prevent the graphite powder inside from splashing to the outside of the mold 4. The top of the top cover 12 is in slight contact with the top of the mold 4. This state has the same effect as the inner edge.

[0030] The upper cover 12 corresponds to the mold 4. A cylinder 10 is fixedly connected to the middle of the crossbeam 9. The extension end of the cylinder 10 passes through the crossbeam 9 and the upper cover 12 and is fixedly connected to a smearing plate 18. Slide rods 17 are fixedly connected to both ends of the upper part of the smearing plate 18, and the slide rods 17 are also slidably connected inside the crossbeam 9 and the upper cover 12. A control cabinet 5 is set on one side of the experimental table 3. When the bottom motor 2 19 is started, it drives the gear 3 20 to rotate. Under the meshing action, the cleat 21 drives the bottom rotating table 8 to rotate. The rotating table 8 drives the material above to cooperate with the smearing plate 18 to complete the smoothing operation during the rotation. The smearing plate 18 and its mounting parts are all made of non-metallic materials, which can effectively avoid the damage caused by metal. The product contains metallic impurities due to corrosion. The scraper is electrically driven. Before smoothing, the scraper plate is set to a height (which can be measured). This height is slightly lower than the material height. During rotation, it is slowly raised and then slowly raised while rotating, smoothing the material gradually. At the same time, the control cabinet 5 in this device can be a PLC control cabinet. The thickness sensor is installed in the middle of the lower part of the upper cover 12, directly above the material feeding area. This installation method allows for direct measurement of the powder layer thickness on the rotary table 8 after the graphite raw material powder is fed onto the rotary table 8. This avoids the influence of subsequent transmission or other operations on the powder layer thickness and can accurately obtain the powder layer thickness information before entering the grinding process.

[0031] Working principle: During use, the electronic scale inside the weighing box 7 monitors the initial weight of the raw material package, the PLC control cabinet 5 sets the target feeding amount, the suction pump 2 starts, and the graphite powder is sucked from the raw material package into the mold 4 on the test bench 3 through the pipeline. The electronic scale provides real-time feedback on the weight difference. When the target value is reached, the suction pump 2 is turned off. After the pumping is completed, the cylinder 11 is started to drive the upper cover 12 to move downwards, completing the closing of the mold 4. Then, the cylinder 10 is started to drive the smearing plate 18 to descend to 1-2cm above the powder layer. Subsequently, the motor 19 at the bottom is started to drive the gear 20 to rotate. Under the meshing action, the cleat 21 drives the bottom rotating table 8 to rotate. The rotating table 8 drives the material above to cooperate with the smearing plate 18 to complete the smoothing operation. Finally, the thickness sensor (laser or ultrasonic optional) is used to detect the thickness of the powder layer after the material is spread, and the data is fed back to the PLC control cabinet 5. If the thickness does not match the set amount, the PLC control cabinet 5 will automatically adjust the suction pump flow rate or the smoothing speed.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
