Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and particularly to a dust-free lifting and quantitative feeding device. Background Art

[0002] With the development of technology, pharmaceutical machinery is used to produce drugs, which are applied to human treatment. Drug raw materials need to be put into the pharmaceutical machinery, and drugs are manufactured in the pharmaceutical machinery. The drug raw materials are lifted to the feeding end of the pharmaceutical machinery under the action of external force and poured into the pharmaceutical machinery.

[0003] In the prior art, drug raw materials are stored in a hopper. An operator grabs the hopper and transports the hopper and the drug raw materials in the hopper to the feeding end of the pharmaceutical machinery. At this time, the hopper and the drug raw materials in the hopper need to undergo manual lifting and manual turning, and are completely dependent on the operator. As a result, the existing drug raw materials rely too much on the operator during the feeding stage, leading to low feeding efficiency of the existing drug raw materials, uneven feeding speed, and derivative problems such as uneven particle size and material blockage. Moreover, it will also cause great labor intensity for workers. Especially for blocky or granular drug raw materials containing fine powder, manual feeding will cause a large amount of dust at the site, pollute the environment, and endanger the health of operators.

[0029] Please refer to the attached Figures 1 to 3 , this embodiment provides a dust-free lifting and quantitative feeding device 100, and the dust-free lifting and quantitative feeding device 100 is used for feeding and feeding drug raw materials. The dust-free lifting and quantitative feeding device 100 includes a frame 10, a feeding bin 20, a lifting mechanism 30, and a flipping mechanism 40.

[0030] The frame 10 serves as a supporting component of the dust-free lifting and quantitative feeding device 100 and is used to support the feeding bin 20, the lifting mechanism 30, and the flipping mechanism 40.

[0031] The feeding bin 20 is arranged on one side of the frame 10. The feeding bin 20 is provided with a storage space 21, and the storage space 21 is used to store drug raw materials so as to facilitate the feeding bin 20 to store drug raw materials.

[0032] The lifting mechanism 30 is arranged on one side of the frame 10 and is connected to the frame 10; the lifting mechanism 30 includes a lifting bracket 31, and the lifting bracket 31 is used to support the hopper containing drug raw materials; the lifting bracket 31 is installed on the frame 10 in a liftable manner and lifts the hopper containing drug raw materials to the flipping station of the frame 10 in the up and down direction.

[0033] At this time, the lifting bracket 31 moves up and down in the up and down direction and supports the hopper containing drug raw materials. The hopper containing drug raw materials moves up and down under the drive of the lifting bracket 31, and the hopper containing drug raw materials is lifted to the flipping station. Therefore, the hopper and the drug raw materials in the hopper are lifted without human intervention, avoiding the human lifting of drug raw materials.

[0034] Among them, the lifting mechanism 30 further includes a first motor 32, two sprockets 33, and a chain 34. The two sprockets 33 are rotatably installed on the frame 10, and the two sprockets 33 are arranged opposite to each other in the vertical direction along the up and down direction. Optionally, the two sprockets 33 are connected to the frame 10 through a first bearing and a first rotating shaft and rotate relative to the frame 10. The chain 34 is sleeved on the two sprockets 33 and pulls the two sprockets 33; the output end of the motor is connected to a sprocket and drives the chain 34 to rotate. The lifting bracket 31 is fixed to the chain 34 and moves up and down along the up and down direction as the chain 34 rotates.

[0035] At this time, the hopper is supported by the lifting bracket 31, and as the lifting bracket 31 moves up and down, the hopper is conveyed to the flipping station under the drive of the lifting bracket 31. The hopper and the pharmaceutical raw materials in the hopper are avoided from being lifted manually, reducing the manual labor of the operator and improving the lifting efficiency of the hopper and the pharmaceutical raw materials in the hopper.

[0036] The flipping mechanism 40 is arranged on one side of the lifting mechanism 30; the flipping mechanism 40 includes a flipping buckle 41. The flipping buckle 41 is used to buckle the hopper containing the pharmaceutical raw materials, and the flipping buckle 41 is arranged relative to the flipping station; the flipping buckle 41 is rotatably installed on the frame 10 and flips the hopper at the flipping station to the feeding bin 20, so that the pharmaceutical raw materials in the hopper enter the feeding bin 20.

[0037] At this time, the flipping buckle 41 buckles the hopper containing the pharmaceutical raw materials when it is at the flipping station. The flipping buckle 41 flips along the axis between the flipping buckle 41 and the frame 10. The hopper containing the pharmaceutical raw materials flips as the flipping buckle 41 flips along the axis between the flipping buckle 41 and the frame 10, and flips the hopper at the flipping station to the feeding bin 20, so that the pharmaceutical raw materials in the hopper enter the feeding bin 20.

The buckling part 412 flips as the flipping part 411 flips along the axis between the flipping buckle 41 and the frame 10.

[0041] Specifically, there are four buckling parts 412. The four buckling parts 412 are all arranged on the lower side of the flipping part 411 and are arranged oppositely, and jointly buckle the opposite two side walls in the hopper. At this time, the opposite two side walls in the hopper are buckled by the buckling parts 412, and the opposite two side walls in the hopper are buckled simultaneously, ensuring that the hopper flips as the buckling part 412 flips. Optionally, the buckling part 412 is in a hook shape.

The plurality of adsorption holes 61 are arranged at intervals along the outer contour of the negative pressure curtain 60, ensuring that the negative pressure curtain 60 adsorbs the dust around the feed inlet of the feed bin 20 when the negative pressure fan 70 is in a negative pressure state.

[0049] The dust-free lifting and metering feeding device 100 further includes a dust collection chamber 80. The dust collection chamber 80 is installed on the frame 10. The dust collection chamber 80 is provided with a dust collection cavity 81 for collecting dust. The dust collection space and the negative pressure curtain 60 are connected by an air pipe. At this time, the plurality of adsorption holes 61 of the negative pressure curtain 60 adsorb the dust at the feed inlet of the feed bin 20 in different directions and transport it to the dust collection space through the air pipe.
