[0025] The following will be combined with Figures 1 - 3 A metering and weighing machine according to an embodiment of the present utility model will be described in detail.
[0026] Embodiment:
[0027] A metering and weighing machine includes:
[0028] Chain conveyor 1, on the upper surface of whose chain, a support plate 7 is fixedly installed. At the four corners of the bottom of the chain conveyor 1, universal wheels 19 are fixedly installed. By setting the universal wheels 19, it is convenient to move the equipment. On the upper surface of the support plate 7, an installation groove 8 is opened. Inside the installation groove 8, a jacking plate 9 is arranged. On the left and right sides of the upper surface of the jacking plate 9, pressure sensors 10 are fixedly installed. On the upper surface of the jacking plate 9, a material barrel 20 is arranged;
[0029] The first mounting bracket 2 is fixedly installed on the upper surface of the right side of the chain conveyor 1. On the upper surface of the first mounting bracket 2, a hopper 3 is fixedly installed. On one side of the hopper 3, a vibration motor 14 is fixedly installed. By the operation of the vibration motor 14, the outer wall of the hopper vibrates, so as to prevent the material from sticking to the inner wall of the hopper 3. On one side of the upper end of the first mounting bracket 2, a mounting plate 4 is fixedly installed. On one side of the mounting plate 4, a first cylinder 5 is fixedly installed. The first cylinder 5 is electrically connected to the pressure sensor 10. At the end of the output shaft of the first cylinder 5, a sealing plate 6 is fixedly installed. The sealing plate 6 is in contact with the discharge port of the hopper 3;
[0030] The connecting rod 11 is fixedly installed at the lower right end of the chain conveyor 1. On one side of the connecting rod 11, a fixing hoop 12 is fixedly installed. Inside the fixing hoop 12, a second cylinder 13 is inserted. Take out the second cylinder 13 from inside the fixing hoop 12 and place it directly below the support plate 7. By the elongation of the second cylinder 13, the jacking plate 9 is jacked up. At this time, the first cylinder 5 expands and contracts to pull out the sealing plate 6 from the bottom of the hopper 3. At this time, the material in the hopper 3 is fed into the material barrel 20. By the pressure sensor 10, the weight of the material barrel 20 is detected. When the material barrel 20 reaches the required weight, the first cylinder 5 elongates to insert the sealing plate 6 back into the bottom of the hopper 3 to seal the hopper 3, so as to realize the metering and weighing of the material. During the metering and weighing process, the material barrel is not in contact with the equipment, and it will not affect the weighing mechanism;
[0031] On the upper surface of the left side of the chain conveyor 1, a second mounting bracket 15 is fixedly installed. On one side of the second mounting bracket 15, a third cylinder 16 is fixedly installed. At the end of the output shaft of the third cylinder 16, a motor 17 is fixedly installed. On the top of the second mounting bracket 15, an electric control cabinet is fixedly installed. The first cylinder 5, the second cylinder 13, the third cylinder 16 and the motor 17 are all electrically connected to the electric control cabinet. At the end of the output shaft of the motor 17, a stirring blade 18 is fixedly installed. After the material metering is completed, the chain conveyor 1 conveys the material barrel to the bottom of the second mounting bracket 15. At this time, the third cylinder 16 elongates to insert the stirring blade 18 into the material barrel 20. By the operation of the motor 17, the stirring blade 18 rotates, so as to stir the material.
[0032] Working principle:
[0033] The support plate 7 is moved to directly below the hopper 3 by the operation of the chain conveyor 1. The second cylinder 13 is taken out from inside the fixing hoop 12 and placed directly below the support plate 7. The second cylinder 13 extends to lift the jacking plate 9. At this time, the first cylinder 5 expands and contracts to withdraw the sealing plate 6 from the bottom of the hopper 3. At this time, the material in the hopper 3 is fed into the inside of the barrel 20. The weight of the barrel 20 is detected by the pressure sensor 10. When the barrel 20 reaches the required weight, the first cylinder 5 extends to insert the sealing plate 6 back into the bottom of the hopper 3 to seal the hopper 3, thereby realizing the metering and weighing of the material. During the metering and weighing process, the barrel does not contact the equipment and will not affect the weighing mechanism.
