[0003] There are areas for improvement in the current market for grinding Chinese medicine. Most of the equipment lacks a precise grinding fineness adjustment structure and can only achieve a fixed fineness of grinding, which cannot adapt to the different grinding fineness requirements of different medicinal materials (such as hard mineral medicinal materials and loose herbal medicinal materials). Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable gap grinding device for grinding Chinese medicinal materials.

Preferably, a solenoid valve is provided at the discharge port of the hopper, and the outlet of the solenoid valve is connected to a corrugated duct, which can be stretched to the feed port of the grinding mechanism.
[0006] Preferably, the grinding mechanism includes a hopper mounted on a secondary support for storing the ground powder. A groove is provided at the top edge of the hopper to install an adjustment component for placing the moving grinding disc and adjusting the position of the fixed grinding disc. The moving grinding disc has a feed hole for feeding the powder. Preferably, the adjusting component includes a support frame installed in a groove at the edge of the material barrel opening, a bearing plate for placing a moving grinding disc is installed on the top of the support frame, a groove is provided on the inner wall of the support frame for sliding connection of a slider, a limiting block for placing a fixed grinding disc is fixedly connected to one side of the slider, the sliding slider drives the limiting block to control the distance between the moving and fixed grinding discs, and the fineness of grinding the medicinal materials is controlled by adjusting the distance between the moving and fixed grinding discs.

[0010] like Figures 1-4 As shown, the adjustable gap grinding device for grinding Chinese medicinal materials includes a main support 1. The main support 1 is constructed of metal to form a stable frame structure. A cutting mechanism 2 is installed at its center for cutting the medicinal materials before grinding. The cutting mechanism 2 includes a hopper 21 installed on the main support 1 and a corrugated conduit 27 connected to the outlet. The hopper 21 has a cylindrical hollow structure and the inner wall is polished to avoid medicinal material residue. The corrugated conduit 27 is made of flexible and wear-resistant material so that its length can be flexibly adjusted according to the position of the subsequent auxiliary support 11. The auxiliary support 11 is set on the main support 1 for installing the grinding mechanism 4. The auxiliary support 11 is fixed to one side of the main support 1 by bolts and is set perpendicular to the main support 1 to ensure the stability of the grinding mechanism 4 after installation. The medicinal materials cut by the cutting mechanism 2 are introduced into the grinding mechanism 4 through the corrugated conduit 27 for grinding and grinding.
[0011] The cutting mechanism 2 also includes a cover 22 that covers the hopper 21. The cover 22 is a circular cover plate that matches the hopper 21 and has sealing strips on the edges to prevent medicinal material fragments from splashing during the cutting process. The hopper 21 is fixed to the cover 22 by a connecting component 23. The connecting component 23 is located on the outside of the hopper 21 near the top to ensure the fixation effect of the cover 22. The center of the cover 22 is equipped with a cutting component for cutting medicinal materials to ensure uniform cutting of the medicinal materials in the hopper 21.
[0012] The connecting component 23 includes mounting blocks 231 installed on both sides of the hopper 21. The mounting blocks 231 are cuboid structures and are welded and fixed to the hopper 21. After the hopper cover 22 is placed on the outer surface of the hopper 21, the sliding inserts 232 on the mounting blocks 231 are inserted into the insertion holes 221 on the outer surface of the hopper cover 22 for limiting their position. The mounting blocks 231 have through holes that match the inserts 232 to allow the inserts 232 to slide smoothly. One end of the inserts 232 is provided with a pull ring for the convenience of workers. The insertion block 232 is used to disassemble and assemble the bin cover 22. A spring 233 is fitted on the insertion block 232, and the two ends of the spring 233 are respectively connected to the outer surface of the insertion block 232 and the bin 21. When the spring 233 is in its natural state, it can push the insertion block 232 to always keep it inserted into the insertion hole 221, thereby limiting the insertion block 232 from displacement under vibration. The insertion hole 221 is opened on the outer edge of the bin cover 22 and its position corresponds to the insertion block 232 to ensure that the insertion block 232 can be accurately inserted.
[0013] The cutting component includes a primary motor 24 mounted on the hopper cover 22. The primary motor 24 is fixed to the upper surface of the hopper cover 22 by a motor bracket, and the motor output shaft passes vertically downward through the hopper cover 22. The output shaft of the primary motor 24 passes through the hopper cover 22 and is connected to a shaft via a coupling. The shaft and the motor output shaft are tightly connected by a coupling, and a mounting groove is opened on the surface of the shaft to fix the cutting blades 25. Several cutting blades 25 are mounted on the outer surface of the shaft. The cutting blades 25 are arranged on the shaft in order of decreasing size from top to bottom. The size of the cutting blades 25 is adapted to the inverted funnel at the discharge port of the hopper 21. The inverted funnel at the discharge port of the hopper 21 adopts a conical structure and is integrally formed with the hopper 21. The bottom opening size of the inverted funnel matches the inlet size of the corrugated conduit 27. As the medicinal material descends into the hopper 21, it can be gradually cut into smaller and smaller pieces by the cutting blades 25 of different sizes, which can pass through the corrugated conduit 27.
[0014] A solenoid valve 26 is installed at the discharge port of the hopper 21. The solenoid valve 26 is fixed to the bottom of the discharge port of the hopper 21 by a flange and communicates with the inside of the hopper 21. The outlet of the solenoid valve 26 is connected to a bellows duct 27. One end of the bellows duct 27 is fixed to the outlet of the solenoid valve 26 by a clamp, and the other end is connected to the feed position of the grinding mechanism 4 in the same way. The bellows duct 27 can be stretched to the feed position of the grinding mechanism 4, and the bellows duct 27 can maintain a stable connection state and will not fall off when stretched to its longest state. The control circuit of the solenoid valve 26 is connected to the subsequent control panel 5 so that the operator can control the opening and closing of the solenoid valve 26.
[0015] The grinding mechanism 4 includes a material bucket 42 mounted on the auxiliary support 11 for storing the ground medicinal powder. The material bucket 42 has a cylindrical structure and a removable bottom cover for easy removal of the ground medicinal powder. A groove is provided at the top edge of the material bucket 42 to install an adjustment component 44. The groove has an annular structure and its depth matches the height of the adjustment component 44. After the adjustment component 44 is installed in the groove, its top is flush with the top of the material bucket 42. The adjustment component 44 is used to place the moving grinding disc 47 and adjust the position of the fixed grinding disc 41. Both the moving grinding disc 47 and the fixed grinding disc 41 have a disc-shaped structure and grinding teeth on their surfaces. The moving grinding disc 47 has a feed hole 471 for feeding. The feed hole 471 is located at an eccentric position on the moving grinding disc 47 and its diameter matches the outlet size of the corrugated guide tube 27 to ensure that the medicinal material can smoothly enter between the moving grinding disc 47 and the fixed grinding disc 41.
[0016] The adjusting assembly 44 includes a support frame 441 installed in a groove at the edge of the opening of the material barrel 42. The support frame 441 has an annular frame structure and its outer side is fitted and fixed to the groove at the top of the material barrel 42. A bearing plate 442 for placing the moving grinding disc 47 is installed on the top of the support frame 441. The bearing plate 442 has a circular flat plate structure and is welded and fixed to the support frame 441. An annular groove matching the moving grinding disc 47 is opened on the surface of the bearing plate 442 so that the moving grinding disc 47 can rotate stably on the bearing plate 442. A groove is opened on the inner wall of the support frame 441 for sliding connection of the slider 444. The groove on the inner wall of the support frame 441 has a strip structure and extends along the support frame 441. The slider 444 is radially arranged such that its outer side fits against the inner wall of the groove and can slide along the length of the groove. A limiting block 443 for placing the fixed grinding disc 41 is fixedly connected to one side of the slider 444. The limiting block 443 has an arc-shaped structure and fits against and is fixed to the outer edge of the fixed grinding disc 41. The sliding slider 444 drives the limiting block 443 to control the distance between the fixed grinding disc 41 and the moving grinding disc 47. When the limiting block 443 slides with the slider 444, it can drive the fixed grinding disc 41 to move synchronously to ensure that the distance between the fixed grinding disc 41 and the moving grinding disc 47 is adjusted evenly. The fineness of grinding medicinal materials is controlled by adjusting the distance between the moving grinding disc 47 and the fixed grinding disc 41.
[0017] Limiting holes 445 are provided on the slider 444 and the support frame 441. The limiting holes 445 are provided on the slider 444 and the support frame 441 at equal intervals and with the same diameter. A limiting pin 446 is inserted into the limiting hole 445 to control the fixed position of the slider 444 after it moves. The limiting pin 446 is a cylindrical metal rod with anti-slip texture on one end. After the limiting pin 446 is inserted into the limiting hole 445, it can remain stable and will not fall off under the vibration generated by the operation of the grinding mechanism 4.
[0018] A second motor 48 is mounted on the auxiliary support 11 via an assembly block. The assembly block has an L-shaped structure, with one end fixed to the auxiliary support 11 by bolts and the other end fixed to the second motor 48 by bolts. The output shaft of the second motor 48 is connected to the turntable 49 via a coupling. The output shaft of the second motor 48 is horizontally positioned and connected to the center of the turntable 49 via a coupling. The second motor 48 drives the turntable 49 to rotate. A hinge seat is provided at the edge of the turntable 49 for mounting the hinge rod 410. The rotation of the turntable 49 controls the hinge rod 410 to pull the moving grinding disc 47 to rotate and grind the medicinal materials. One end of the hinge rod 410 is connected to the hinge seat of the turntable 49 via a pin, and the other end is connected to the outer edge of the moving grinding disc 47 in the same way. The length of the hinge rod 410 is set so that when the turntable 49 rotates one revolution, it can drive the moving grinding disc 47 to complete one complete rotation.
[0019] A ladder 3 is installed on the main support 1 for workers to climb and transport materials into the silo 21. The ladder 3 is made of metal and is fixed to the outside of the main support 1 with bolts. The steps of the ladder 3 are evenly spaced to facilitate workers' climbing. A guardrail is installed at the top of the ladder 3 to prevent workers from falling while climbing. A control panel 5 for controlling electrical components is installed on the secondary support 11. The control panel 5 has a waterproof and dustproof shell and is fixed to the side of the secondary support 11 with a bracket. The surface of the control panel 5 is equipped with buttons and indicator lights to control the working status of each motor and solenoid valve 26 and to display the operating status of the equipment. The control panel 5 has a circuit board inside and is connected to each electrical component through wires to ensure stable signal transmission.
[0020] Working principle Workers climb up the ladder 3 on the main support 1 to the position of the hopper 21, pull the pull ring of the insert 232 in the connecting component 23 to disengage the insert 232 from the insertion hole 221 of the hopper cover 22, open the hopper cover 22 and pour the medicine to be ground into the hopper 21, then close the hopper cover 22 and release the pull ring. The spring 233 pushes the insert 232 into the insertion hole 221 to complete the fixing of the hopper cover 22.
[0021] The first motor 24 is started by the control panel 5 on the auxiliary support 11. The first motor 24 drives the shaft and the cutting blade 25 on the shaft to rotate. The medicinal materials in the hopper 21 gradually descend under their own gravity and are gradually cut by the cutting blades 25 of different sizes from large to small. After the cutting is completed, the solenoid valve 26 of the discharge port of the hopper 21 is opened by the control panel 5. The cut medicinal materials enter the corrugated guide tube 27 through the inverted funnel of the discharge port of the hopper 21 and are transported along the corrugated guide tube 27 to the feed hole 471 of the moving grinding disc 47 of the grinding mechanism 4.
[0022] Depending on the required fineness of the powder, the operator slides the slider 444 on the inner wall of the support frame 441 in the adjustment component 44, which drives the limit block 443 and the fixed grinding disc 41 to move to adjust the distance between the fixed grinding disc 41 and the moving grinding disc 47. After the adjustment is in place, the limit pin 446 is inserted into the limit hole 445 corresponding to the slider 444 and the support frame 441 to fix the position of the slider 444.
[0023] Start motor 48 via control panel 5. Motor 48 drives turntable 49 to rotate. Turntable 49 pulls moving grinding disc 47 to rotate on bearing disc 442 via hinge rod 410. Cut medicinal materials entering through feed hole 471 fall between moving grinding disc 47 and fixed grinding disc 41. Under the relative rotation of the two, they are ground into medicinal powder. The ground medicinal powder naturally falls into material hopper 42 for storage. After the grinding work is completed, turn off all motors and solenoid valve 26, and open the bottom cover of material hopper 42 to take out the medicinal powder.
