Technical Field

[0001] The utility model relates to the technical field of automatic powder feeding, in particular to a powder feeding device capable of automatic high-precision quantitative feeding. Background Art

[0002] In the glass melting method of cement chemical composition analysis, the corresponding sample powder and flux need to be manually and quantitatively added into the crucible container. The existing sample powder and flux are quantitatively measured by experienced experimenters using a scale with an accuracy of 0.1 mg to repeatedly weigh until the powder and flux with the required accuracy are obtained. This is inefficient and requires a high level of work experience on the part of the personnel.

[0003] The existing method can only be calculated by manual weighing, which is not only labor-intensive but also prone to errors. It is also unable to automatically match the feeding speed according to the required material quantity, and the efficiency is low. Based on the above reasons, the utility model designs a powder feeding device that can automatically and accurately feed the powder. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1-4As shown, a powder feeding device capable of automatic high-precision quantitative feeding includes a frame 1 and a frame 2 8, the frame 1 and the frame 2 8 are connected with a moving component that allows both to move, the moving component includes a linear module 11, the linear module 11 is respectively connected to the frame 1 and the frame 2 8 through two slide blocks, a vibrating feeder 2 is installed in the frame 1, the vibrating feeder 2 is connected to a conveying trough 3, the top of the conveying trough 3 is connected to a silo 4 for feeding multiple materials, and the side of the silo 4 is connected to a silo installed on the frame 1 The pendulum mechanism 5 is provided on the frame 8, and the pendulum mechanism 5 is used for vibrating and removing the residual materials attached to the inner wall of the silo 4. The frame 8 is installed with a conveying trough 2 12, and the conveying trough 2 12 is connected to the silo 2 7 for feeding single materials. The specification of the silo 4 is smaller than that of the silo 2 7. The end of the conveying trough 3 is connected to a dust collecting mechanism 6, and the dust collecting mechanism 6 is used for processing and collecting the residual materials in the silo 4 and the conveying trough 3. The end parts of the conveying trough 3 and the conveying trough 2 12 are connected to a crucible container 10, and a scale module 9 is arranged below the crucible container 10.

[0021] The pendulum mechanism 5 includes a swing cylinder 51, the top of which is connected to a swing transmission block 52, the other end of which is connected to a protective nylon block 53, the protective nylon block 53 abuts against the outer wall of the silo 4, after the equipment completes the quantitative feeding work, the swing cylinder 51 drives the swing transmission block 52 to rotate and knock the silo 4, vibrating and removing the residual material attached to the inner wall of the silo 4 into the conveying trough 3, and the subsequent dust collection mechanism 6 sucks out the residual material under negative pressure, and the dust collection mechanism 6 comprises a telescopic cylinder 61, the movable end of the telescopic cylinder 61 is connected to a suction nozzle mounting plate 62, the other end of the suction nozzle mounting plate 62 is mounted with a dust collecting suction nozzle 63, the telescopic cylinder 61 is kept in an extended state in the standby state, so as to facilitate the conveying trough 3 to vibrate and feed materials into the crucible container 10; the telescopic cylinder 61 is kept in a retracted state in the dust collecting state, and the dust collecting suction nozzle 63 moves to the conveying trough 3, starts negative pressure dust collection, and cleans the residual materials in the conveying trough 3 and the crucible container 10.

[0022] When in use, a required quantitative material sample is poured into the silo 4 manually or by a robot. After the feeding is completed, the vibrating feeder 2 vibrates so that the material in the silo 4 is quantitatively fed to the crucible container 10 through the conveying trough 3. At this time, the position of the frame 1 in the linear module 11 is in a state where the conveying trough 3 and the crucible container 10 cooperate. Then, the material weight is recorded and fed back in real time through the scale module 9. When the required weight is reached, the action of the vibrating feeder 2 is stopped. After the quantitative feeding process is completed, the pendulum mechanism 5 is used to feed the silo 4. Vibration and knocking are performed to remove residual materials on the warehouse wall, and then the residual materials in the conveying trough and the silo 4 are subjected to negative pressure dust collection through the dust collecting mechanism 6. Then, the linear module 11 drives the frame 1 and the frame 2 8 to move as a whole, and switches to the state where the silo 2 7 and the crucible container 10 cooperate with each other. At this time, a large amount of single raw material in the silo 2 7 will be directly poured into the crucible container 10 for quantitative feeding. Among them, the silo 2 7 is only for feeding a single material, and its feeding amount is large, so there is no need to set a pendulum mechanism 5 and a dust collecting mechanism 6.
