[0002] Drug grinding, as a key link in drug processing, aims to refine drug raw materials into fine powders to better meet the needs of drug use or subsequent processes. This process usually starts with moderate drying of the drug raw materials to ensure their stability and improve grinding efficiency. Subsequently, professional grinders are used for pulverization to obtain particle size distribution that meets the requirements.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-Figure 9 The present invention provides a technical solution: an energy-saving Chinese medicinal material grinding device, comprising a bracket 1, a reduction motor 2 is arranged on the bracket 1, the output end of the reduction motor 2 is connected to a mounting frame 3, and also comprises a grinding head 4 and a driving component 5 arranged above the grinding head 4, the driving component 5 can drive the grinding head 4 to perform a grinding operation; a grinding cylinder 8 is arranged at the bottom of the mounting frame 3, which is located below the grinding head 4. During grinding, the grinding head 4 rotates in the grinding cylinder 8 to grind the medicinal material, a material receiving cylinder 9 is arranged on the outer side of the bottom of the grinding cylinder 8, and through grooves connected to the material receiving cylinder 9 are opened on both sides of the grinding cylinder 8, and a through groove connected to the material receiving cylinder 9 is arranged on the bracket 1. There is a guide rail 10, and the reduction motor 2 can drive the mounting frame 3 to reciprocate along the guide rail 10. Turning components 6 are arranged on both sides of the guide rail 10. When the mounting frame 3 drives the grinding cylinder 8 to move to the turning components 6 on both sides, the turning component 6 is connected with the grinding cylinder 8 to spray gas into the grinding cylinder 8, which can blow the ground powder in the grinding cylinder 8 to the through groove and then enter the receiving cylinder 9, and can also turn the powder at the bottom, so that some large pieces of medicinal materials can directly contact the grinding head 4, thereby increasing the grinding efficiency and reducing energy consumption. Among them, the motors used in this embodiment are all energy-saving motors, which further reduce energy consumption.

[0035] A slider 11 is fixedly arranged at the rear of the mounting frame 3. The slider 11 is slidably arranged in the guide rail 10. The guide rail 10 is arc-shaped and its rotation center coincides with the output axis of the reduction motor 2. Therefore, the reduction motor 2 can drive the mounting frame 3 to rotate during forward and reverse transmission. When the mounting frame 3 rotates, it drives the slider 11 to move along the guide rail 10.

[0036] The driving assembly 5 includes a driving motor 51 fixedly mounted on the top of the mounting frame 3, a sleeve rod 52 is provided at the output end of the driving motor 51, a shaft rod 53 is slidably provided inside the sleeve rod 52, the bottom end of the shaft rod 53 is fixedly connected to the grinding head 4, a supporting spring 54 is provided at the top end of the shaft rod 53, and the two ends of the supporting spring 54 are respectively connected to the shaft rod 53 and the inside of the sleeve rod 52, a magnetic block 55 is provided at the top end of the shaft rod 53, and an electromagnet 56 is provided inside the sleeve rod 52, and the electromagnet 56 repels the magnetic block 55 after being energized;

[0037] During grinding, by turning the electromagnet 56 on and off, the shaft 53 can be driven to slide inside the sleeve 52, thereby driving the grinding head 4 to move up and down relative to the grinding cylinder 8, so that some large pieces of medicinal materials can be crushed. When the grinding head 4 moves upward relative to the grinding cylinder 8, the chamber space between the grinding head 4 and the grinding cylinder 8 becomes larger. At this time, when the turning component 6 blows air into the grinding cylinder 8, a better turning effect can be achieved, and the ground medicinal materials can also be cooled.

[0038] A fixing ring 12 is fixedly provided on the outer side of the grinding cylinder 8, and a thread is provided on the inner side of the fixing ring 12. An external thread is opened on the outer side of the top of the receiving cylinder 9. The receiving cylinder 9 is installed on the fixing ring 12 through the thread. The receiving cylinder 9 and the grinding cylinder 8 are connected by threads and can be easily disassembled and assembled, which is convenient for taking the powder. Filters are provided in the grooves on both sides of the grinding cylinder 8 to prevent powder that does not meet the fineness standards from entering the receiving cylinder 9.

[0039] A bellows 13 is provided on the outside of the grinding head 4, and a connecting magnetic ring 14 is connected to the bottom end of the bellows 13. A fixed magnetic ring 15 is fixedly provided on the grinding cylinder 8. A slot 16 for cooperating with the fixed magnetic ring 15 is provided at the bottom of the connecting magnetic ring 14. Through the cooperation of the connecting magnetic ring 14 and the fixed magnetic ring 15, the bottom of the bellows 13 is fixedly installed on the grinding cylinder 8, so that a closed chamber is formed between the grinding head 4 and the grinding cylinder 8 to avoid waste caused by leakage of medicine powder.

[0040] The turning assembly 6 includes two fixed cylinders 61 respectively arranged at the two ends of the guide rail 10, a piston 62 is slidably arranged in the fixed cylinder 61, a sliding rod 63 is connected to the piston 62, a connecting spring 64 is arranged in the fixed cylinder 61, and the two ends of the connecting spring 64 are respectively connected to the piston 62 and the inside of the fixed cylinder 61, a cross plate 65 is fixedly arranged on the slider 11, and when the slider 11 moves along the guide rail 10, it can drive the cross plate 65 to abut against the sliding rod 63 to move it, and a one-way valve for one-way air intake is also arranged on the fixed cylinder 61, and gas tanks 66 are arranged at both ends of the guide rail 10, and the gas tank 66 is connected to the fixed cylinder 61 through a pipeline, and a connecting pipe 67 is arranged on the gas tank 66, and a conducting unit 7 is arranged in the connecting pipe 67, and branch pipes 68 are arranged on both sides of the grinding cylinder 8, and when the grinding cylinder 8 drives the branch pipe 68 to move into the connecting pipe 67, the branch pipe 68 abuts against the conducting unit 7 to move it, thereby making the connecting pipe 67 conductive;

[0041] When the mounting frame 3 drives the slider 11 and the cross plate 65 to move, the cross plate 65 abuts against the slide rod 63 to drive it to move, and the slide rod 63 drives the piston 62 to move to squeeze the gas in the fixed cylinder 61 into the gas tank 66. At this time, the air pressure in the gas tank 66 increases. When the branch pipe 68 abuts against the conduction unit 7 to make the connecting pipe 67 conductive, the gas in the gas tank 66 is released and enters the grinding cylinder 8 through the branch pipe 68. At this time, the grinding cylinder 8 is in an inclined state, and the medicinal materials in the grinding cylinder 8 are concentrated at the inclined position. At this time, the air flow blown out from the branch pipe 68 blows towards the medicinal materials, and some lighter powdered medicinal materials are blown up, move along the inner wall of the grinding cylinder 8 to another through groove, and enter the receiving cylinder 9 through the filter screen.

[0042] The end of the connecting tube 67 is fixedly connected to the fixing tube 69, the conducting unit 7 comprises a block 71 movably arranged in the fixing tube 69, connecting plates 72 are arranged on both sides of the block 71, a side plate 73 is fixedly arranged on the inner wall of the connecting tube 67, a guide rod 74 penetrating the side plate 73 is arranged on the connecting plate 72, a return spring 75 is arranged on the outer side of the guide rod 74, and both ends of the return spring 75 are respectively connected to the connecting plate 72 and the side plate 73;

[0043] When the branch pipe 68 abuts against the blocking block 71 , as the grinding cylinder 8 moves, the branch pipe 68 drives the blocking block 71 to move into the connecting pipe 67 . At this time, the gas in the gas tank 66 enters the branch pipe 68 through the connecting pipe 67 and the fixed pipe 69 .

[0044] A plurality of notches are formed on the outer side of the end of the branch pipe 68 . When the branch pipe 68 abuts against the blocking block 71 , gas can enter the branch pipe 68 through the notches.

[0045] A plurality of protrusions 17 are fixedly provided on both sides of the guide rail 10, and a vibration rod 18 is provided at the bottom of the mounting frame 3. When the mounting frame 3 moves along the guide rail 10 to both sides of the guide rail 10, the vibration rod 18 contacts the plurality of protrusions 17 in turn to generate vibrations, and the vibrations are transmitted to the grinding cylinder 8. Then, when the material is turned over, the powder at the filter screen can pass through better through the vibration to avoid blockage.

[0046] In summary, when grinding, first place the medicinal material in the grinding cylinder 8, then connect the bottom of the bellows 13 to the grinding cylinder 8, then start the device, the reduction motor 2 drives the mounting frame 3 to swing left and right, and at the same time, the driving motor 51 drives the grinding head 4 to rotate to grind the medicinal material. When grinding, the grinding head 4 can be moved up and down by powering on and off the electromagnet 56 to enhance the grinding effect, and when the mounting frame 3 swings toward both sides, the slider 11 drives the cross plate 65 to move, and the cross plate 65 drives the piston 62 to move so that the gas tank The air pressure in 66 increases. When the mounting frame 3 moves to the outermost side, the branch pipe 68 is inserted into the fixed pipe 69 to drive the block 71 to move, so that the connecting pipe 67 is connected, and the gas in the gas tank 66 enters the grinding cylinder 8. At this time, the grinding cylinder 8 is in an inclined state. The blown air flow can blow the powder to both sides of the grinding cylinder 8 and enter the receiving cylinder 9 through the through groove. At the same time, the powder can be blown away, leaving large pieces of medicinal materials in place. When grinding again, the large pieces of medicinal materials can be first ground in an energy-saving manner to speed up the grinding efficiency.

[0047] Example 2: Please refer to Fig.10 , Example 2 has the same main structure as Example 1, except that a hopper 19 is fixedly provided on one side of the bracket 1, a feed pipe 20 is provided at the bottom of the hopper 19, an automatic feed valve is provided in the feed pipe 20, and a slot for inserting the feed pipe 20 is provided on one side of the bellows 13. When the mounting frame 3 drives the grinding cylinder 8 to move to the side of the hopper 19, the feed pipe 20 can extend into the bellows 13 through the slot, and feed the grinding cylinder 8 through the automatic feed valve, thereby achieving continuous grinding. The specific feeding cycle can be adjusted according to the grinding rate, that is, it is related to the physical properties of the medicinal materials and the grinding speed of the grinding head 4. The specific structure and use principle of the automatic feed valve are both prior art and will not be repeated here.
