Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material production and processing, in particular to a feeding mechanism for a medicinal material chopping machine. Background Art

[0002] Medicinal materials are raw materials for making medicines. In China, they especially refer to Chinese medicinal materials, that is, raw materials of Chinese medicine that have not been processed or made into finished products. Chinese medicine is a traditional Chinese medicinal material. Chinese medicine culture has a long history and is profound. It not only contains thousands of years of Chinese medicine civilization, but also integrates the unique cultural phenomenon of combining Chinese and Western medicine created by modern Western medicine civilization. It is an important part of China's excellent culture. Chinese medicinal materials refer to native medicinal materials used under the guidance of traditional medical skills to treat diseases. Generally, traditional Chinese medicinal materials pay attention to authentic medicinal materials, which refer to medicinal materials produced in a region with specific natural conditions and ecological environment. The production is relatively concentrated, and the cultivation technology, harvesting and processing are certain. In the production and processing of Chinese medicinal materials, it is necessary to use the feeding mechanism structure to introduce the medicinal materials into the chopping machine for chopping.

[0003] A common feeding mechanism for a medicine chopping machine, after the raw materials (i.e. medicinal materials) are put into the feed port of the feeding mechanism, the feeding structure of the inner cavity of the feeding mechanism (such as a feeding belt or a threaded feeding blade, etc.) is opened and works under the action of the corresponding transmission structure and driving device, so that the raw materials entering the inner cavity of the feeding mechanism are transported to the discharge port and discharged. At the same time, the discharge port of the feeding mechanism is connected to the feed port of the medicine chopping machine, so that the raw materials are discharged into the inside of the medicine chopping machine for chopping. This is the common use method and structure of the feeding mechanism for medicine chopping machines. The traditional feeding mechanism for medicine chopping machines is prone to blockage and stagnation during the feeding process, so that the raw materials cannot enter through the feed port of the feeding mechanism, resulting in the inability to transport the raw materials to the medicine chopping machine for processing. Some feeding mechanisms for medicine chopping machines adopt a conveyor chain design that rotates relatively at the top and bottom, so that the medicinal materials can be evenly and stably transported to the medicine chopping machine, and are not prone to jamming. This method speeds up the feeding speed of the feeding port of the feeding mechanism, so that the raw materials can be fed smoothly into the feeding port of the feeding mechanism. However, there are many reasons for the blockage of the raw materials at the feeding port of the feeding mechanism. It is impossible to completely prevent the blockage of the raw materials by only using the common conveying structure. Therefore, a feeding mechanism for a medicine chopping machine is proposed.

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a feeding mechanism for a medicine chopping machine to solve the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding mechanism for a medicine chopping machine, including an equipment housing, a connecting cover plate is transversely installed on the top of the equipment housing, and a feeding funnel is longitudinally connected to the top of the feeding hole at the center position of the top of the connecting cover plate, a rotating rod is longitudinally added at the center position of the inner cavity of the feeding funnel, and a spiral feeding piece is installed at the center position and the upper part of the outer surface of the rotating rod, the bottom end of the rotating rod extends into the upper part of the center position of the inner cavity of the equipment housing, and the bottom end of the rotating rod is longitudinally coaxially connected to a driving motor. After the raw materials are poured into the interior of the feeding funnel, the driving motor drives the spiral feeding piece to rotate through the rotating rod, thereby guiding the raw materials in the inner cavity of the feeding funnel down. On the one hand, it can avoid the occurrence of excessive raw materials in the inner cavity of the feeding funnel to form a blockage phenomenon; on the other hand, it can achieve quantitative feeding, thereby avoiding excessive feeding and causing the raw materials to be blocked at the discharge end of the equipment housing.

[0008] Preferably, semicircular ear plates are installed at the center positions of both sides of the device housing, and threaded screws are installed longitudinally just below the center positions of the bottoms of the semicircular ear plates, and support base plates are longitudinally added to the bottom ends of the threaded screws.

The rotating circular plate drives the threaded screw to rotate, so that the sliding plate and the connecting rod are lifted and lowered according to the rotation direction of the threaded screw. When rising, the connecting rod drives the device housing to rise and fall through the semicircular ear plate, so that the discharge end at the bottom of the device housing can be connected with the feed end of the medicine chopping machine.

[0010] Preferably, the lower part of the outer surface of the rotating rod is sleeved with a conical guide plate, and the lower parts of both sides of the conical guide plate are transversely installed with cross bars, and the outer ends of the cross bars are connected to the corresponding positions of the inner wall of the equipment housing. When the rotating rod rotates, the raw materials are guided to be discharged, and part of the raw materials fall to the top surface of the conical guide plate and slide down along the surface of the conical guide plate, thereby preventing part of the raw materials from being accumulated inside the equipment housing and affecting the next batch of different raw materials from being transported to the inside of the medicine chopping machine for processing.

[0011] Preferably, quantitative unloading plates are hinged on both sides of the lower part of the center of the inner cavity of the device housing, and guide columns are installed horizontally at the front and rear ends just below the bottom of the quantitative unloading plates, and the two ends of the guide columns are connected to the corresponding positions of the inner wall of the device housing. When a certain amount of raw materials falls to the top of the quantitative unloading plates, the two groups of quantitative unloading plates rotate downward with the outer hinge as the center, so that the quantitative raw materials are unloaded, avoiding too much raw materials entering the medicine chopping machine, which leads to the phenomenon of incomplete processing of the raw materials in the medicine chopping machine.

[0012] Preferably, both sides of the outer surface of the guide column are sleeved with reset springs, both sides of the center position of the outer surface of the guide column are sleeved with sliding blocks, and the top of the sliding block is hinged with a first movable rod, the top of the first movable rod is hinged with a second movable rod, and the top of the second movable rod is hinged with a third movable rod, and the top of the third movable rod is connected to the corresponding position of the bottom of the quantitative unloading plate.

[0022] The utility model provides a technical solution, a feeding mechanism for a medicine chopping machine, including an equipment housing 1, a connecting cover plate 2, a feeding funnel 3, a rotating rod 4, a spiral feeding sheet 5, a driving motor 6, a semicircular ear plate 7, a threaded screw 8, a rotating circular plate 9, a conical guide plate 10, a quantitative unloading plate 11, a guide column 12 and a reset spring 13, please refer to Figure 1 A connecting cover plate 2 is installed horizontally on the top of the equipment housing 1, and a feeding funnel 3 is longitudinally connected to the top of the feeding hole at the center position of the top of the connecting cover plate 2. A rotating rod 4 is longitudinally added at the center position of the inner cavity of the feeding funnel 3, and a spiral feeding sheet 5 is installed at the center position and upper part of the outer surface of the rotating rod 4. Please refer to Figure 2 The bottom end of the rotating rod 4 extends into the upper center of the inner cavity of the equipment housing 1, and the bottom end of the rotating rod 4 is longitudinally coaxially connected to a driving motor 6. After the raw materials are poured into the inside of the feeding funnel 3, the driving motor 6 drives the spiral feeding sheet 5 to rotate through the rotating rod 4, thereby guiding the raw materials in the inner cavity of the feeding funnel 3 down. On the one hand, it can avoid the occurrence of excessive raw materials in the inner cavity of the feeding funnel 3. The phenomenon of clogging and stagnation can be avoided; on the other hand, quantitative feeding can be achieved, thereby avoiding excessive feeding causing the raw materials to be blocked and stuck at the discharge end of the equipment housing 1.

[0023] See also Figure 1, semicircular ear plates 7 are installed at the center positions of both sides of the equipment housing 1, and threaded screws 8 are installed longitudinally just below the center positions of the bottoms of the semicircular ear plates 7, and support base plates are longitudinally added to the bottom ends of the threaded screws 8. The threaded screws 8 support the equipment housing 1 through the support base plates and the semicircular ear plates 7. Rotating circular plates 9 are installed at the lower part of the outer surface of the threaded screws 8, and sliding plates are sleeved at the lower part of the center positions of the outer surface of the threaded screws 8, and connecting rods are longitudinally installed at the center positions of both sides of the top of the sliding plates, and the tops of the connecting rods fit in with the corresponding positions of the bottoms of the semicircular ear plates 7. The rotating circular plate 9 drives the threaded screw 8 to rotate, so that the sliding plate and the connecting rod are lifted and lowered according to the rotation direction of the threaded screw 8. When rising, the connecting rod drives the equipment housing 1 to rise and fall through the semicircular ear plates 7, so that the discharge end at the bottom of the equipment housing 1 can be connected with the feed end of the medicine chopping machine.

[0024] See also Figure 2 , a conical guide plate 10 is sleeved on the lower part of the outer surface of the rotating rod 4, and cross bars are transversely installed on the lower parts of both sides of the conical guide plate 10, and the outer ends of the cross bars are connected to the corresponding positions of the inner wall of the equipment housing 1. When the rotating rod 4 rotates, the raw materials are guided to be discharged, and part of the raw materials fall to the top surface of the conical guide plate 10 and slide down along the surface of the conical guide plate 10, thereby avoiding the accumulation of part of the raw materials inside the equipment housing 1, affecting the next batch of different raw materials from being transported to the inside of the medicine chopping machine for processing. Quantitative discharge plates 11 are hinged on both sides of the lower part of the inner center of the inner cavity of the equipment housing 1, and guide columns 12 are transversely installed at the front and rear ends just below the bottom of the quantitative discharge plate 11, and the two ends of the guide columns 12 are connected to the corresponding positions of the inner wall of the equipment housing 1. When a certain amount of raw materials falls to the top of the quantitative unloading plate 11, the two groups of quantitative unloading plates 11 rotate downward with the outer hinge as the center, so that the quantitative raw materials are unloaded, avoiding too much raw materials entering the medicine chopper, which leads to incomplete processing of the raw materials in the medicine chopper.

[0025] See also Figure 3 , both sides of the outer surface of the guide column 12 are sleeved with reset springs 13, both sides of the center position of the outer surface of the guide column 12 are sleeved with sliding blocks, and the top of the sliding block is hinged with a first movable rod, the top of the first movable rod is hinged with a second movable rod, and the top of the second movable rod is hinged with a third movable rod, and the top of the third movable rod is connected to the corresponding position of the bottom of the quantitative unloading plate 11. When the quantitative unloading plate 11 rotates downward, the corresponding sliding block is driven by the third movable rod, the second movable rod and the first movable rod to move along the outer surface of the guide column 12, and the corresponding reset spring 13 is squeezed. After the raw material on the quantitative unloading plate 11 is unloaded, it can be reset under the action of the reset spring 13.

[0026] The working principle of the device is as follows: after the raw materials are poured into the inside of the feed hopper 3, the driving motor 6 drives the spiral feed sheet 5 to rotate through the rotating rod 4, thereby guiding the raw materials in the inner cavity of the feed hopper 3 down. On the one hand, it can avoid the occurrence of excessive raw materials blocking the inner cavity of the feed hopper 3; on the other hand, it can achieve quantitative feeding, thereby avoiding excessive feeding causing the raw materials to be blocked at the discharge end of the equipment housing 1. When the rotating rod 4 rotates, the raw materials are guided down, and part of the raw materials fall to the top surface of the conical guide plate 10 and slide down along the surface of the conical guide plate 10, thereby avoiding the accumulation of part of the raw materials inside the equipment housing 1. The next batch of different raw materials is transported to the inside of the medicine chopping machine for processing. When a certain amount of raw materials falls to the top of the quantitative unloading plate 11, the two groups of quantitative unloading plates 11 rotate downward with the outer hinge as the center, so that the quantitative raw materials are unloaded. When the quantitative unloading plate 11 rotates downward, the corresponding sliding block is driven by the third movable rod, the second movable rod and the first movable rod to move along the outer surface of the guide column 12, and the corresponding reset spring 13 is squeezed. After the raw materials on the quantitative unloading plate 11 are unloaded, they can be reset under the action of the reset spring 13 to avoid too much raw materials entering the medicine chopping machine, which will lead to incomplete processing of the raw materials in the medicine chopping machine.
