Description

Technical Field

[0001] This invention relates to the field of medicinal material grinding technology, and more specifically, to a grinding device for dispensing medicines. Background Technology

[0002] Traditional Chinese medicine gynecology clinics use a wide variety of medications. Doctors will select appropriate medications based on the patient's specific condition and constitution, and then combine them for treatment. Angelica sinensis, Paeonia lactiflora, Ligusticum chuanxiong, Salvia miltiorrhiza, and Leonurus japonicus are all commonly used Chinese herbs in clinical practice. When different herbs are combined and ground, they can form herbal pairs with different effects such as nourishing yin, invigorating qi, promoting blood circulation, and replenishing blood. The grinding process is usually completed using an electric grinder.

[0003] Chinese Patent No. CN202411979786.6 discloses a novel medicine grinding mill. This mill is equipped with multiple hoppers and corresponding grinding heads. When the servo motor is started, it can drive multiple grinding heads to rotate synchronously, efficiently grinding the Chinese medicinal materials in the hoppers. During the grinding process, as the grinding heads rotate, the Chinese medicinal materials in the hoppers are gradually pulverized, thus continuously reducing the space occupied by the medicinal materials. At this time, the spring will drive the grinding head to continuously press down, so that the grinding head can continuously grind until the material is completely turned into powder, ensuring a more thorough grinding process.

[0004] However, although the above solution can provide downward thrust to the grinding head through the spring, when the grinding head comes into contact with the Chinese medicinal materials, the materials exert a reverse force on the grinding head, resulting in unstable pressure on the grinding head. Specifically, in the initial stage of grinding, the materials are in the form of lumps or granules with uneven surfaces. When the grinding head encounters a high point, the reaction force increases sharply, pushing the grinding head upward. At this time, the spring is compressed, causing the grinding pressure to increase instantaneously. After passing the high point, the pressure decreases rapidly. This fluctuation is not conducive to achieving stable and efficient grinding.

[0005] Therefore, in view of the above-mentioned technical defects, it is necessary to propose a grinding device for dispensing medicines. Summary of the Invention

[0006] The present invention aims to address the above-mentioned technical deficiencies by proposing a grinding device for dispensing medicines. When in use, the device can ensure that the downward-moving grinding head can maintain a "rigid" pressurized state, thereby allowing the grinding head to apply high pressure stably and continuously to the medicinal materials during operation, ultimately significantly improving the grinding efficiency of the medicinal materials.

[0007] The present invention provides a grinding device for dispensing medicine, including a device body, a connecting cover detachably disposed on the left side of the device body, and a grinding component disposed along the inside of the device body; The outer side of the device body is connected to the inside, and an inner cavity is opened. Two material hoppers are arranged at intervals on the inner side of the connecting cover, and the Chinese medicinal materials to be ground are placed in the material hoppers. The grinding assembly includes a bracket, a support plate, and a grinding head. The bracket is movably disposed on the right side of the inner cavity, the support plate is disposed on the left side of the bracket, and the grinding head is rotatably disposed on the left side of the bottom surface of the support plate. The grinding head is opposite to the inside of the hopper. A vertical groove is formed on the right side of the inner wall of the inner cavity. A slider is slidably disposed above the inside of the groove, and one end of the slider is connected to the bracket. A receiving groove is formed at the top of the inner wall of the groove, and a first spring is disposed between the receiving groove and the top surface of the slider. An installation groove is formed on both sides of the inner wall of the groove. A retaining strip is disposed at the middle of the inner wall of the installation groove. Multiple inclined sawtooth-shaped retaining grooves are equidistantly formed on the end of the retaining strip facing the slider. A first slot is formed on both sides of the outer wall of the slider. A movable block is slidably disposed in the first slot and on the outer side of the slider. The movable block is opposite to the retaining groove. A second spring is disposed between the inner end of the first slot and the slider. A movable strip is slidably disposed in the slider along the vertical direction, and the upper and lower ends of the movable strip extend toward the top and bottom of the slider, respectively. When the slider moves downward, the slot can squeeze the movable block. When the lower end of the movable bar contacts the bottom surface of the slide groove, the movable block can retract into the first slot. When the top end of the movable bar contacts the top surface of the slide groove, the retracted movable block can be reset.

[0008] Preferably, a second slot with a long strip structure is vertically formed in front of the first slot along the inside of the slider. The second slot is connected to the top surface, bottom surface of the slider and the inside of the first slot. The movable strip is slidably arranged at the outer end of the second slot in the vertical direction. A rectangular push plate is slidably arranged at the lower inside of the second slot along the inner end. The push plate is fixedly connected to the outer surface of the movable strip. An inwardly inclined slope is formed between the upper end of the outer surface of the push plate and the top surface. A baffle is fixedly arranged at the lower part of the slope along the outer surface of the push plate.

[0009] Preferably, the front side of the movable block is provided with a cylindrical fixed column, and one end of the fixed column extends into the second slot. When the movable block is in the extended state, the fixed column and the highest point of the inclined end of the push plate are opposite each other. When the movable bar drives the push plate to move upward, the inclined end of the push plate can contact the fixed column. The pressure applied by the first spring is greater than the pressure applied by the second spring.

[0010] Preferably, the connecting cover is an L-shaped plate, and two circular fixing plates are respectively arranged at intervals from top to bottom on the inner side of the connecting cover, wherein the upper and lower surfaces of the fixing plates are connected and have circular receiving grooves. The feeding hopper has a hemispherical structure, and the bottom surface of the feeding hopper is adapted to be embedded in the receiving groove. A fixing pin is provided on the outer side of the connecting cover to the inner wall, and one end of the fixing pin is threaded to the outer side of the feeding hopper.

[0011] Preferably, the grinding assembly further includes a transmission tube, a connecting rod, a transmission wheel, and a transmission belt. The transmission tube is cylindrical, and its upper and lower ends are rotatably and fixedly disposed with respect to the top and bottom surfaces of the bracket and the support plate, respectively. The connecting rod is rotatably disposed on the left side of the top surface and the left side of the bottom surface of the support plate in a vertical direction, and the lower end of the connecting rod is connected to the center of the top surface of the grinding head. The transmission wheels are respectively disposed on the outer surfaces of the connecting rod and the transmission tube, wherein the transmission wheel of the connecting rod and the transmission wheel of the transmission tube are disposed opposite to each other, and the transmission belt is adapted to be disposed between the transmission wheel of the transmission tube and the transmission wheel of the connecting rod.

[0012] Preferably, a rotating rod is vertically and rotatably arranged on the right side of the inner cavity along the top and bottom surfaces. A motor is arranged on the top surface of the equipment body, and the transmission shaft of the motor is connected to the rotating rod. The inner side of the transmission tube is slidably connected to the outer side of the rotating rod. The inner side of the transmission tube is connected to the top and bottom surfaces and has a vertically formed elongated limiting groove. A long strip-shaped limiting strip is fixedly arranged on the outer side of the rotating rod along the vertical direction, and the limiting strip is also slidably connected to the inner wall of the limiting groove.

[0013] Preferably, the top surface of the grinding head is also provided with a cover plate with a "bottle cap" structure, wherein the inner diameter of the bottom surface of the cover plate is adapted to the diameter of the top surface of the hopper, and the inner end of the bottom surface of the cover plate is separated from the outer side of the hopper.

[0014] Preferably, a positioning block is also provided at the upper end of the outer wall of the movable strip.

[0015] Preferably, a connecting groove is provided between the right side of the main body of the equipment and the slide groove, a lifting block is provided on the right side of the main body of the equipment, and one end of the lifting block passes through the connecting groove and is connected to the outer surface of the slider.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The grinding device of the present invention, by setting corresponding retaining strips and movable blocks between the inner wall of the chute and the outer side of the slider, when the grinding head gradually crushes the medicinal materials in the hopper, the elastic force of the first spring will force the grinding head and the slider to move downward together. At the same time, under the pressure of the second spring, the movable block will contact the serrated groove at the retaining strip. Since the groove is inclined, the slider can only move downward, thus avoiding the upward rebound caused by the medicinal materials exerting a reverse force on the grinding head. In this way, the grinding head can maintain a "rigid" pressurized state, thereby ensuring that the high pressure can act stably and continuously on the medicinal materials, and ultimately significantly improving the grinding efficiency of the medicinal materials.

[0017] 2. The grinding device of the present invention, by providing a second slot, a movable strip, and a push plate inside the slider, allows the user to apply downward pressure to the slider after the medicinal materials in the hopper have been ground. This causes the slider to come close to the bottom surface of the groove and push the movable strip upward within the second slot. During this process, the push plate will contact the fixed column, causing the movable block to retract into the first slot. After retraction, the movable block can no longer contact the slot at the locking strip. At this point, the user can drive the entire support and grinding head upward. As it moves upward, the grinding head will move away from the inside of the hopper, making it easy to remove the connecting cover on the left side of the device body. After removal, the medicinal materials in the hopper can be collected.

[0018] 3. The grinding device of the present invention is provided with a sliding groove and a movable bar. When the slider moves upward, the slider can approach the top surface of the sliding groove, which can push the movable bar downward. After the movable bar moves downward, the push plate will disengage from the fixed column. At this time, the pressure of the second spring can make the movable block extend out of the second slot. This mechanism ensures that the movable block can re-contact the locking strip in the sliding groove, thereby facilitating the grinding operation of the next batch of Chinese medicinal materials.

[0034] As attached Figure 1 To be continued Figure 9 As shown: A grinding device for dispensing medicine includes a device body 1, a connecting cover 2 installed on the left side of the device body 1, and a grinding assembly 3 disposed inside the device body 1. An inner cavity 11 is formed from the left side of the outer wall of the device body 1 to the inside. The connecting cover 2 is an L-shaped plate and is fastened to the inner cavity 11 on the left side of the device body 1. Two circular fixing plates 21 are respectively arranged at intervals from bottom to top on the inner side of the connecting cover 2. Circular receiving grooves 23 are formed on the upper and lower surfaces of the fixing plates 21. A hemispherical hopper 22 is provided above the fixed plate 21. The bottom surface of the hopper 22 is fitted into the receiving groove 23. A fixing pin is provided from the outer side of the connecting cover 2 to the inner wall, and one end of the fixing pin is threaded to the outer side of the hopper 22. The grinding assembly 3 is movably arranged above the fixed plate 21. The grinding assembly 3 includes a spherical grinding head 37. The grinding head 37 is opposite to the inside of the hopper 22. The outer spherical surface of the grinding head 37 and the inner spherical surface of the hopper 22 are both frosted and made of stainless steel.

[0035] In the above structure, the feeding hopper 22 can be securely installed on the fixed plate 21 through the connecting cover 2 and the fixing pin. After installation, the connecting cover 2 is engaged with the inner cavity 11 on the left side of the equipment body 1, so that the feeding hopper 22 can smoothly enter the inner cavity 11. Then, the grinding assembly 3 drives the grinding head 37 to move downward, so that the grinding head 37 can enter the inside of the feeding hopper 22. When the grinding head 37 comes into contact with the Chinese medicinal materials, the grinding head 37 is started to rotate, so that the Chinese medicinal materials in the feeding hopper 22 can be ground and pressed.

[0036] like Figures 2 to 5As shown, the grinding assembly 3 also includes a bracket 31, a support plate 32, a transmission tube 33, a connecting rod 36, a transmission wheel 38, and a transmission belt 39. The bracket 31 is movably disposed on the right side of the inner cavity 11 in a vertical direction. A groove 4 is vertically opened on the right side of the inner wall of the inner cavity 11. A slider 5 is slidably disposed above the inside of the groove 4, and one end of the slider 5 is connected to the bracket 31. The support plate 32 includes two plates, which are fixedly installed on the left side of the bracket 31 in a horizontal direction. The transmission tube 33 is in the shape of a round tube, and its two ends are rotatably and fixedly disposed with respect to the top and bottom surfaces of the bracket 31 and the support plate 32, respectively. The connecting rod 36 is rotatably disposed on the left side of the top surface and the left side of the bottom surface of the support plate 32 in a vertical direction, and the lower end of the connecting rod 36 is also connected to the center of the top surface of the grinding head 37. The drive wheels 38 are respectively disposed on the outer sides of the connecting rod 36 and the drive tube 33, and the drive wheels 38 of the connecting rod 36 and the drive tube 33 are correspondingly arranged. The drive belt 39 is adapted to be disposed between the drive wheels 38 of the connecting rod 36 and the drive tube 33. In use, when the drive tube 33 rotates, the rotational power can be transmitted to the connecting rod 36 through the drive wheels 38 and the drive belt 39, so that the connecting rod 36 can drive the grinding head 37 to rotate. During rotation, the grinding head 37 can grind and press the Chinese medicinal materials in the hopper 22.

[0037] Specifically, such as Figure 2 and Figure 5 As shown, a rotating rod 13 is vertically and rotatably installed on the right side of the inner cavity 11 along the top and bottom surfaces. A motor 12 is installed on the top surface of the device body 1, and the drive shaft of the motor 12 is connected to the rotating rod 13. The inner side of the transmission tube 33 is slidably connected to the outer side of the rotating rod 13. The inner side of the transmission tube 33 is connected to the top and bottom surfaces and has a vertically formed elongated limiting groove 34. An elongated limiting strip 35 is fixedly installed on the outer side of the rotating rod 13 in the vertical direction, and the limiting strip 35 is also slidably connected to the inner wall of the limiting groove 34. This design allows the transmission tube 33 to move up and down along the outer side of the rotating rod 13, and the rotating rod 13 can drive the transmission tube 33 to rotate through the limiting strip 35 and the limiting groove 34, thus providing rotational power to the transmission tube 33 through the rotating rod 13.

[0038] Specifically, such as Figure 2 and Figure 3As shown, a "bottle cap" shaped cover plate 371 is also provided on the top surface of the grinding head 37. The inner diameter of the bottom surface of the cover plate 371 is adapted to the diameter of the top surface of the hopper 22, and the inner end of the bottom surface of the cover plate 371 is spaced apart from the outer side of the hopper 22. This design allows the outer side of the hopper 22 to be effectively sealed by the bottle cap structure of the cover plate 371 when the grinding head 37 moves downward. In this sealed state, the Chinese medicinal materials can be safely kept in the hopper 22, which facilitates the subsequent grinding and pressing process.

[0039] Specifically, such as Figures 2 to 4 As shown, a notch is provided on the right side of the bottom surface of the connecting cover 2. The notch is opposite to the rotating rod 13 and is connected to the top surface of the connecting cover 2. This design allows the rotating rod 13 to pass through the notch after the connecting cover 2 is installed, thus maintaining the installation stability of the rotating rod 13 and avoiding interference with the rotation of the rotating rod 13 after the connecting cover 2 is installed.

[0040] like Figure 2 and Figure 6 As shown, the slide groove 4 has a receiving groove 41 at the top of the inner wall, and a first spring 42 is provided between the receiving groove 41 and the top surface of the slider 5. In use, the first spring 42 is used to apply downward pressure to the slider 5. The slide groove 4 has a vertical and connected mounting groove 43 on both sides of the inner wall. A retaining strip 44 is provided at the middle of the inner wall of the mounting groove 43. The end of the retaining strip 44 facing the slider 5 has multiple inclined sawtooth-shaped retaining grooves at equal intervals. The outer wall of the slider 5 has first slots 51 on both sides in the horizontal direction. A movable block 52 is slidably disposed between the outer end of the first slot 51 and the outer surface of the slider 5. The movable block 52 is disposed opposite to the retaining strip 44, and the end of the movable block 52 facing the retaining strip 44 has an inclined surface that matches the retaining groove. A second spring 53 is disposed between the inner end of the second slot 55 and the slider 5. The pressure applied by the first spring 42 is greater than the pressure applied by the second spring 53. In use, the first spring 42 can apply an outward pushing force to the movable block 52. This pushing force can make the inclined end of the movable block 52 contact the serrated retaining groove. Because the retaining groove is inclined, the movable block 52 can only slide down from top to bottom on the outer side of the retaining strip 44. This mechanism can effectively prevent the movable block 52 from rebounding upward due to external force during the downward sliding process.

[0041] In the above structure, when the grinding head 37 grinds and crushes the Chinese medicinal materials in the hopper 22, the medicinal materials will be gradually crushed, which will reduce the volume of the materials in the hopper 22. At this time, under the action of the first spring 42, the slider 5 and the support 31 will be subjected to downward pressure, thereby ensuring that the grinding head 37 is in full contact with the Chinese medicinal materials. Since the slider 5 is provided with a movable block 52, and the movable block 52 is only allowed to slide downward on the outer side of the retaining strip 44, the upward thrust generated when the grinding head 37 contacts the medicinal materials cannot drive the support 31 and the movable block 52 to move upward. This design ensures that the grinding head 37 is in full contact with the medicinal materials, thereby achieving stable grinding of the medicinal materials.

[0042] like Figures 6 to 9 As shown, a long strip-shaped second slot 55 is vertically formed in front of the first slot 51 along the interior of the slider 5. The second slot 55 is connected to the top surface, bottom surface of the slider 5 and the interior of the first slot 51. A movable strip 56 is slidably arranged on the outer side of the second slot 55 in the vertical direction. The upper end of the movable strip 56 extends upward toward the top of the slider 5, and the lower end of the movable strip 56 extends downward toward the bottom of the slider 5. A rectangular push plate 57 is slidably arranged on the inner side of the lower interior of the second slot 55. The push plate 57 is fixedly connected to the outer surface of the movable strip 56. An inwardly inclined slope is formed between the upper end of the outer surface of the push plate 57 and the top surface. A baffle 58 is fixedly arranged on the outer surface of the push plate 57 below the slope. In use, when the slider 5 moves the movable bar 56 to the lower end of the slide groove 4, the bottom surface of the movable bar 56 can contact the bottom surface of the slide groove 4. After contact, the movable bar 56 can be pushed upward, which facilitates the retraction of the movable block 52 into the first slot 51. Similarly, when the slider 5 moves the movable bar 56 to the upper end of the slide groove 4, the top surface of the movable bar 56 can contact the top surface of the slide groove 4. After contact, the movable bar 56 can be pushed downward, which can then drive the push plate 57 downward. After downward movement, due to the lack of restriction on the movable block 52, the movable block 52 can extend out of the first slot 51 again. A cylindrical fixed post 54 is provided on the front side of the movable block 52. One end of the fixed post 54 extends into the second slot 55. When the movable block 52 is in the extended state, the fixed post 54 is positioned opposite to the highest point of the inclined end of the push plate 57. When the movable bar 56 drives the push plate 57 to move upward, the inclined end of the push plate 57 can contact the fixed post 54. This design allows the bottom surface of the movable bar 56 to contact the bottom surface of the slide 4 when it moves to the lower end of the slide 4. After contact, the movable bar 56 and the push plate 57 can be pushed upward. Since the inclined end of the push plate 57 is opposite to the fixed column 54, when the push plate 57 continues to move upward, it can apply an inward pushing force to the fixed column 54 through the inclined end of the push plate 57. This allows the fixed column 54 to drive the movable block 52 to move inward. After the movement, the movable block 52 can be completely retracted into the first slot 51. At the same time, after the upward-moving push plate 57 reaches the limit position, the fixed column 54 just contacts the baffle 58. Under the action of the baffle 58 and the fixed column 54, the upward-moving push plate 57 can be limited.

[0043] In the above structure, after the medicinal materials in the hopper 22 have been ground, the downward-moving movable block 52 has moved away from the locking strip 44, while the movable strip 56 is close to the bottom surface of the slide groove 4. Subsequently, the user applies downward pressure to the slider 5, which forces the slider 5 to press against the bottom surface of the slide groove 4, thereby pushing the movable strip 56 upward in the second slot 55. In this way, the upward-moving push plate 57 can apply a pushing force to the fixed column 54, thereby causing the movable block 52 to retract into the first slot 51. After retraction, the movable block 52 cannot contact the locking groove at the locking strip 44, thus facilitating the upward movement of the entire bracket 31 and the grinding head 37. After the upward movement, the grinding head 37 can be removed from the inside of the hopper 22. Finally, the user can remove the connecting cover 2 from the left side of the equipment body 1. After removal, the medicinal materials in the hopper 22 can be collected and processed. On the other hand, since the movable block 52 will squeeze the second spring 53 in the first slot 51 after retraction, and the elastic force of the second spring 53 will act in the opposite direction on the fixed post 54, when the bracket 31 drives the slider 5 to move upward, the fixed post 54 can hold the entire push plate 57 against it. This can accurately limit the suspended movable bar 56, thereby preventing the movable block 52 from extending due to displacement. This mechanism ensures that the slider 5 can move upward smoothly, thereby preventing the movable block 52 from getting stuck due to contact with the locking bar 44 during the movement.

[0044] It should be noted that after the medicinal materials are ground, the grinding head 37 will come into contact with the powder. Due to the gaps between the powder particles, the powder can be compressed to a certain extent, which provides pressing space for the grinding head 37 (i.e., allowing the slider 5 to continue moving downward). Therefore, when the slider 5 drives the support 31 to move downward, the grinding head 37 will also move downward along with the material hopper 22. This design ensures that the grinding head 37 will not interfere with the movement of the movable bar 56 and the movable block 52, thereby allowing the slider 5 to move up and down normally in the groove 4.

[0045] Specifically, such as Figures 7 to 9 As shown, a positioning block 59 for limiting the movement is also provided on the upper end of the outer wall of the movable strip 56. During use, when the movable strip 56 moves downward, the positioning block 59 can contact the top surface of the slider 5. This design can limit the sliding distance of the movable strip 56 by using the positioning block 59. This ensures that after the movable strip 56 slides, its upper and lower ends can stably protrude from the top and bottom surfaces of the slider 5. This mechanism allows the upper and lower ends of the movable strip 56 to normally contact the top and bottom surfaces of the groove 4.

[0046] Specifically, such as Figure 2 As shown, to facilitate the upward movement of the support 31 and the grinding head 37, a connecting groove 6 is provided between the right side of the main body of the device and the slide 4, and a lifting block 61 is provided on the right side of the main body of the device. One end of the lifting block 61 passes through the connecting groove 6 and is connected to the outer surface of the slider 5. This design allows the user to move the slider 5 and the support 31 upward using the lifting block 61.

[0047] The following is the specific usage process of the present invention: First, the Chinese medicinal materials to be pulverized are placed into the feeding hopper 22. Then, the support 31 is lifted upward by the lifting block 61. After lifting, the entire connecting cover 2 is snapped into the inner cavity 11. At this time, the inner spherical surface of the feeding hopper 22 will be aligned with the grinding head 37. After alignment, the lifting block 61 is released, and the support 31 and the grinding head 37 will move downward under the action of the first spring 42, so that the grinding head 37 contacts the Chinese medicinal materials in the feeding hopper 22. Then, the user starts the motor 12 to drive the rotating rod 13 to rotate, thereby driving the grinding head 37 to grind and crush the Chinese medicinal materials. As the Chinese medicinal materials are gradually pulverized, the elastic force of the first spring 42 will force the grinding head 37 to gradually press down, continuing to grind the Chinese medicinal materials until they are powdered.

[0048] At the same time, when the slider 5 moves downward in the groove 4, the movable block 52 on the outside of the slider 5 will contact the groove at the locking strip 44. This mechanism ensures that the slider 5 can only slide downward and will not rebound upward due to external force (i.e., the reverse force exerted by the medicinal material on the grinding head 37). In this way, the grinding head 37 can maintain a "rigid" pressurized state, so that the high pressure acts stably and continuously on the medicinal material, thereby improving the grinding efficiency of the medicinal material.

[0049] Finally, after the medicinal materials in the hopper 22 have been ground, the user needs to apply downward pressure to the slider 5. This will cause the slider 5 to come close to the bottom surface of the groove 4 and push the movable strip 56 upward in the second slot 55. During this process, the push plate 57 will contact the fixed column 54, causing the movable block 52 to retract into the first slot 51. After retraction, the movable block 52 can no longer contact the slot at the locking strip 44. At this time, the user can drive the entire bracket 31 and the grinding head 37 upward. As it moves upward, the grinding head 37 will move away from the inside of the hopper 22. Subsequently, the user can remove the connecting cover 2 from the left side of the equipment body 1. After removal, the medicinal materials in the hopper 22 can be collected and processed.

[0050] Finally, it should be noted that the above embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them.
