Description

Technical Field

[0001] The present invention relates to the technical field of crushing, and particularly relates to a crushing device and process for lizards in the bone-connecting and tendon-reconnecting tablets. Background Art

[0002] The bone-connecting and tendon-reconnecting tablet is a Chinese patent medicine for promoting blood circulation to remove blood stasis, reducing swelling and alleviating pain. It has been on the market in China for many years and has a definite curative effect in clinical treatment of soft tissue injuries, fractures, etc. At present, the preparation of the bone-connecting and tendon-reconnecting tablets requires the use of medicinal materials such as lizards, drynaria rhizomes, and dioscorea nipponica roots. During the preparation process, the crushing treatment of lizard medicinal materials will be involved. Traditional crushing equipment can only perform single crushing treatment on the medicinal material raw materials, resulting in some medicinal material raw materials not being crushed, leading to different particle sizes of the crushed medicinal material raw materials, that is, the crushing of the medicinal material raw materials is uneven.

[0003] To solve the above problems, a Chinese patent with the publication number CN110665621B discloses a medicinal material crushing and grinding device, including a main body, which is provided with a connected crushing chamber and grinding chamber; a crushing component is rotatably arranged inside the crushing chamber; a grinding hopper is arranged inside the grinding chamber, and the grinding hopper is arranged directly below the discharge port of the crushing chamber; a grinding roller is rotatably arranged at the center position inside the grinding hopper, and discharge holes are arranged in an array at the bottom of the grinding hopper; connecting rods are fixedly installed on both sides of the bottom of the grinding hopper; the connecting rods penetrate through the bottom of the main body, and a reciprocating block is fixedly connected to the end of the connecting rod far away from the grinding hopper; a first elastic member is sleeved outside the connecting rod, and both ends of the first elastic member are respectively fixedly installed on the main body and the reciprocating block, and an eccentric wheel is in rolling contact with the upper end of the reciprocating block, and the eccentric wheel is传动连接 with a B motor through a belt; the B motor is fixedly installed at the bottom of the main body; this patent can perform two crushing treatments on the medicinal material raw materials, making the raw material crushing more uniform.

[0004] During the actual use of the above patent, the crushing component can perform the first crushing treatment on the medicinal material raw materials, but there will still be some medicinal material raw materials that are not crushed. Moreover, since there is no screening structure at the discharge port, the medicinal material raw materials after the first crushing treatment directly enter the grinding hopper through the discharge port; however, since the distance between the grinding hopper and the grinding roller is a fixed value, when the size of the uncrushed medicinal material raw materials is greater than the distance between the grinding hopper and the grinding roller, then the uncrushed medicinal material raw materials will stay at the top of the grinding hopper, and thus cannot be grinded by the grinding roller, that is, the utilization rate of the medicinal material raw materials is reduced; in addition, as the use time prolongs, more uncrushed medicinal material raw materials will accumulate at the top of the grinding hopper, thereby causing blockage of the discharge port and resulting in inability to perform grinding treatment. Summary of the Invention

[0005] The present invention aims to provide a crushing device for lizards in the bone-connecting and tendon-reconnecting tablets to solve the problem that the existing equipment cannot completely crush the medicinal material raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pulverizing device for lizards used in bone-setting and tendon-repairing patches, comprising a box body with an inlet and an outlet; a pulverizing mechanism, a partition, and a grinding mechanism are arranged sequentially from top to bottom inside the box body; the pulverizing mechanism includes inclined grooves on both sides of the inner wall of the box body, with movable blocks slidably connected in the inclined grooves, the two movable blocks moving in opposite directions, and a plurality of first pulverizing teeth at the bottom of the movable blocks; and a power mechanism for driving the movable blocks to reciprocate along the path of the inclined grooves; the partition is inverted V-shaped, with a plurality of second pulverizing teeth at the top of the partition for engaging with the first pulverizing teeth; screening plates are connected to both sides of the partition, and through holes are provided on both sides of the partition; the grinding mechanism includes grinding sections disposed on both sides of the box body, the grinding sections being located below the through holes.

[0007] The principle and advantages of this scheme are:

[0008] 1. In this solution, lizard medicinal materials are placed into the box through the feed inlet, allowing them to fall onto a partition plate through the gap between two movable blocks. A power mechanism drives the movable blocks to reciprocate along an inclined groove, causing the two blocks to approach and separate. When the two blocks approach, they simultaneously move towards the partition plate, bringing the first and second crushing teeth closer together. The first and second crushing teeth then crush the lizard medicinal materials. Qualified lizard medicinal materials fall through a sieve plate and through holes into the grinding section for further grinding, resulting in medicinal granules that are discharged from the outlet. Compared to existing technologies, after crushing by the first and second crushing teeth, lizard medicinal materials that are not of the correct size are blocked by the sieve plate and remain at the top of the partition plate, awaiting further crushing by the first and second crushing teeth. This ensures that all lizard medicinal materials are crushed, resulting in a more uniform and comprehensive crushing effect.

[0009] 2. Because the partition is an inverted V-shape, the lizard medicine is evenly distributed to both sides of the partition, meaning that the amount of lizard medicine on one side of the partition will not be too much, so that the first and second crushing teeth can crush the lizard medicine more effectively.

[0010] Furthermore, the screening plate includes a fixed plate connected to the partition and a number of screening holes vertically and equidistantly opened on the fixed plate.

[0011] With the above setup, after the lizard medicinal material is crushed by the first and second crushing teeth, the lizard medicinal material of qualified size moves through the sieve holes towards the through holes.

[0012] Furthermore, both sides of the partition are provided with vertical guide grooves, the fixed plate is slidably connected to the guide grooves, a first spring is provided between the fixed plate and the partition, and the fixed plate is located on the movement trajectory of the movable block; the bottom of the fixed plate is provided with a vertical hole, which communicates with the screening hole; both sides of the bottom of the partition are provided with support blocks, and cleaning blocks are provided on the support blocks, which are slidably connected to the vertical hole.

[0013] With the above configuration, during the downward movement of the movable block along the inclined groove, the movable block presses the fixed plate along the guide groove and moves downward, stretching the first spring; during the downward movement of the fixed plate, the cleaning block moves upward relative to the fixed plate within the vertical hole; during the upward movement of the movable block along the inclined groove, the pressing effect of the movable block on the fixed plate disappears, causing the fixed plate to return to its original position under the action of the first spring; during the upward movement of the fixed plate, the cleaning block moves upward relative to the fixed plate within the vertical hole; during the lizard medicine pulverization process, some medicine residue may remain on the sieve hole. The vertical movement of the fixed plate and the relative vertical movement of the cleaning block within the vertical hole can clean the medicine residue in the sieve hole, thereby preventing clogging of the sieve hole.

[0014] Furthermore, both sides of the housing are rotatably connected to a rotating shaft. The rotating shaft has a vertical groove along the axial direction of the rotating shaft. A slider is slidably connected in the groove. The slider has a round shaft. The round shaft has several brush layers that abut against the fixed plate at equal intervals around the circumference. The round shaft has an annular groove. An annular block is rotatably connected in the annular groove. A linkage block is provided between the annular block and the fixed plate. It also includes a drive mechanism for driving the rotating shaft to rotate.

[0015] With the above setup, the drive mechanism rotates the shaft, which in turn rotates the slider, which in turn rotates the round shaft, which in turn rotates the brush layer. This allows the brush layer to clean the dregs on the fixed plate, thus preventing clogging of the sieve holes. Furthermore, during the vertical reciprocating motion of the fixed plate, the fixed plate, through the linkage block and the ring block, can drive the round shaft and slider to move vertically synchronously, which in turn causes the brush layer to move vertically as well, ensuring that the brush layer can continuously clean the fixed plate. In addition, as the shredded lizard medicinal materials of the correct size move from the sieve holes towards the through holes, the rotating brush layer can disperse the shredded lizard medicinal materials, thus preventing them from piling up.

[0016] Furthermore, the power mechanism includes a side groove formed on the inner wall of the housing and a side block fixed to the side wall of the movable block. A first motor is provided in the side groove, and a cam is coaxially connected to the output shaft of the first motor. Bottom blocks are provided on both sides of the bottom of the side block, and both bottom blocks abut against the cam.

[0017] With the above configuration, the output shaft of the first motor drives the cam to rotate, causing the cam's protrusion to intermittently press the two bottom blocks, thereby driving the side blocks to move laterally back and forth; during the lateral back and forth movement of the side blocks, the movable blocks move back and forth along the path of the inclined groove, thus realizing the approach and separation of the two movable blocks.

[0018] Furthermore, the drive mechanism includes a belt and a bottom groove opened on the side wall of the housing. The bottom groove is connected to the side groove, and the rotating shaft is rotatably connected to the bottom groove. The belt is sleeved on the rotating shaft and the output shaft of the first motor.

[0019] With the above setup, the output shaft of the first motor drives the rotating shaft to rotate via a belt.

[0020] Furthermore, it also includes liquid nitrogen pipes running through both sides of the enclosure, with the liquid nitrogen pipes fixed to the bottom of the partition.

[0021] With the above setup, since the liquid nitrogen tube is fixed to the bottom of the partition and the liquid nitrogen can flow continuously inside the liquid nitrogen tube, the heat generated during the pulverization process can be absorbed and carried away by the liquid nitrogen, thus ensuring that the lizard medicine can be pulverized at low temperature.

[0022] Furthermore, both ends of the liquid nitrogen tube are rotatably connected to a sleeve, and the sleeve is provided with fan blades at equal intervals around the circumference, with the fan blades located below the through hole; the sleeve is provided with several side holes at equal intervals around the circumference, with the side holes located between two adjacent fan blades.

[0023] With the above setup, the shredded lizard medicinal material of the correct size moves downward through the sieve holes and through holes, causing it to fall into the gap between two adjacent fan blades. This allows the shredded lizard medicinal material to enter the side hole and come into contact with the liquid nitrogen tube, thus removing excess heat from the shredded lizard medicinal material. The two adjacent fan blades also act as a barrier, prolonging the contact time between the shredded lizard medicinal material and the liquid nitrogen tube, enhancing the heat absorption effect. Furthermore, the weight of the shredded lizard medicinal material compresses the fan blades, causing the sleeve to rotate. This rotation of the fan blades disperses the lizard medicinal material, preventing it from piling up.

[0024] Furthermore, the grinding section includes two second motors, which are fixed to the housing. The output shafts of the second motors are coaxially connected to grinding rollers, and the two grinding rollers rotate in opposite directions.

[0025] With the above setup, the lizard medicinal material that meets the required size after being crushed continues to move downwards. The output shaft of the second motor drives the grinding roller to rotate, and the two grinding rollers rotate in opposite directions, so that the lizard medicinal material is ground under the action of the two grinding rollers.

[0026] The present invention also aims to provide a process for pulverizing medicinal materials using a lizard-based pulverizing device in bone-setting and tendon-repairing tablets, in order to solve the problem that existing equipment cannot completely pulverize medicinal raw materials.

[0027] To achieve the above objectives, the present invention adopts the following technical solution: a process for pulverizing lizard bone-setting and tendon-repairing tablets using a pulverizing device, comprising the following steps:

[0028] Step 1: Place the lizard medicine into the box through the feed inlet;

[0029] Step 2: Start the first and second motors to pulverize the lizard medicine inside the chamber; introduce liquid nitrogen into the liquid nitrogen pipe to pulverize the lizard medicine at low temperature inside the chamber.

[0030] Step 3: The powder that has been pulverized is discharged through the outlet. Attached Figure Description

[0036] Example

[0037] The basics are as follows: Figure 1 Appendix Figure 2 and attached Figure 3 As shown: A shredding device for lizards used in bone and tendon repair patches includes a box body 10. The box body 10 has an inlet 11 and an outlet 12. The inlet 11 is located at the top of the box body 10, and there are two outlets 12, which are respectively located on the bottom sides of the box body 10.

[0038] The housing 10 is provided with a crushing mechanism, a partition 40 and a grinding mechanism from top to bottom. The crushing mechanism includes inclined grooves 20 on both sides of the inner wall of the housing 10. Movable blocks 21 are slidably connected in the inclined grooves 20. The two movable blocks 21 move in opposite directions. Several first crushing teeth 22 are fixed to the bottom of the movable blocks 21. In the initial state, there is a gap between the two movable blocks 21, which is vertically opposite to the feed inlet 11. The housing also includes a power mechanism for driving the movable blocks 21 to reciprocate along the path of the inclined grooves 20. The power mechanism includes a side groove 30 on the inner wall of the housing 10 and a side block 31 fixed to the side wall of the movable block 21. A first motor 32 is fixed in the side groove 30. A cam 33 is coaxially connected to the output shaft of the first motor 32. Bottom blocks 34 are fixed to both sides of the bottom of the side block 31. Both bottom blocks 34 abut against the cam 33. The side blocks 31 and bottom blocks 34 can move horizontally and vertically in the side groove 30.

[0039] The partition 40 is inverted V-shaped, with the turning point of the partition 40 located between two movable blocks 21. Several second crushing teeth 41 for cooperating with the first crushing teeth 22 are fixedly connected to the top of the partition 40. Through holes 42 are opened on both sides of the partition 40. Screening plates are connected to both sides of the partition 40. The screening plates include a fixed plate 43 and several screening holes 44 vertically and equidistantly opened on the fixed plate 43. Guide grooves are vertically opened on both sides of the partition 40. The fixed plate 43 is slidably connected to the guide grooves. A first spring 45 is fixedly connected between the fixed plate 43 and the partition 40. The fixed plate 43 is located on the movement trajectory of the movable block 21. A vertical hole 46 is opened at the bottom of the fixed plate 43, and the vertical hole 46 communicates with the screening holes 44. Support blocks 47 are fixedly connected to both sides of the bottom of the partition 40. Cleaning blocks 48 are fixedly connected to the support blocks 47, and the cleaning blocks 48 are slidably connected to the vertical holes 46.

[0040] The housing 10 has rotating shafts 50 rotatably connected to both sides. A sliding groove is vertically opened on the rotating shaft 50 along the axial direction of the rotating shaft 50. A slider 51 is slidably connected in the sliding groove. A round shaft 52 is fixed to the slider 51. Several brush layers 53 that abut against the fixed plate 43 are fixedly connected to the round shaft 52 circumferentially at equal intervals. An annular groove is opened on the round shaft 52. An annular block 54 is rotatably connected in the annular groove. A linkage block 55 is fixed between the annular block 54 and the fixed plate 43. The housing 10 also includes a drive mechanism for driving the rotating shaft 50 to rotate. The drive mechanism includes a belt 56 and a bottom groove 57 opened on the side wall of the housing 10. The bottom groove 57 is connected to the side groove 30. The rotating shaft 50 is rotatably connected to the bottom groove 57. The belt 56 is sleeved on the rotating shaft 50 and the output shaft of the first motor 32.

[0041] It also includes a liquid nitrogen pipe 60 that runs through both sides of the housing 10, allowing liquid nitrogen to flow continuously within the liquid nitrogen pipe 60. The liquid nitrogen pipe 60 is fixedly connected to the bottom of the partition 40. Both ends of the liquid nitrogen pipe 60 are rotatably connected to a sleeve 61. Fan blades 62 are fixedly connected to the sleeve 61 at equal intervals in the circumferential direction. The fan blades 62 are located below the through hole 42. Several side holes 63 are opened at equal intervals in the circumferential direction on the sleeve 61. The side holes 63 are located between two adjacent fan blades 62.

[0042] The grinding mechanism includes grinding sections disposed on both sides inside the housing 10, with the grinding sections located below the through hole 42; a stop block 80 is fixedly connected inside the housing 10, with the stop block 80 located between the two grinding sections. The grinding section includes two second motors, which are fixedly connected to the housing 10, and the output shafts of the second motors are coaxially connected to grinding rollers 70, with the two grinding rollers 70 rotating in opposite directions.

[0043] The specific implementation process is as follows:

[0044] When in use, the lizard medicine is placed into the box 10 through the feed inlet 11, so that the lizard medicine falls onto the partition 40 through the gap between the two movable blocks 21; since the partition 40 is an inverted V-shape, the lizard medicine is evenly distributed on both sides of the partition 40.

[0045] Liquid nitrogen is introduced into the liquid nitrogen tube 60, and the first motor 32 and the second motor are started. The output shaft of the first motor 32 drives the cam 33 to rotate, so that the protrusion of the cam 33 intermittently squeezes the two bottom blocks 34, thereby driving the side block 31 to move laterally back and forth. During the lateral back and forth movement of the side block 31, the movable block 21 moves back and forth along the path of the inclined groove 20, that is, the two movable blocks 21 are brought closer and separated.

[0046] When the two movable blocks 21 approach each other, they move towards the partition 40 simultaneously, causing the first crushing tooth 22 and the second crushing tooth 41 to approach each other. This means that the lizard medicine is crushed by the first crushing tooth 22 and the second crushing tooth 41. The lizard medicine with the correct size moves through the sieve hole 44 towards the through hole 42, while the lizard medicine with the wrong size is blocked by the fixed plate 43 and remains on the top of the partition 40, waiting for the first crushing tooth 22 and the second crushing tooth 41 to crush it again. This ensures that all the lizard medicine is crushed, resulting in a more uniform and comprehensive crushing effect.

[0047] During the downward movement of the movable block 21 along the path of the inclined groove 20, the movable block 21 presses the fixed plate 43 downward along the path of the guide groove, and the first spring 45 is stretched; during the downward movement of the fixed plate 43, the cleaning block 48 moves upward relative to the fixed plate 43 in the vertical hole 46; during the upward movement of the movable block 21 along the path of the inclined groove 20, the pressing effect of the movable block 21 on the fixed plate 43 disappears, so that the fixed plate 43 is reset upward under the action of the first spring 45; during the upward movement of the fixed plate 43, the cleaning block 48 moves upward relative to the fixed plate 43 in the vertical hole 46; during the lizard medicine pulverization, there may be residue left on the sieve hole 44. The residue in the sieve hole 44 can be cleaned by the vertical movement of the fixed plate 43 and the relative vertical movement of the cleaning block 48 in the vertical hole 46, thereby avoiding the clogging of the sieve hole 44.

[0048] The output shaft of the first motor 32 drives the rotating shaft 50 to rotate via the belt 56. The rotating shaft 50 drives the slider 51 to rotate, and the slider 51 drives the round shaft 52 to rotate, which in turn drives the brush layer 53 to rotate. This allows the brush layer 53 to clean the dregs on the fixed plate 43, thus preventing the sieve hole 44 from becoming clogged. Furthermore, during the vertical reciprocating motion of the fixed plate 43, the fixed plate 43 can drive the round shaft 52 and the slider 51 to move vertically in sync via the linkage block 55 and the annular block 54, which in turn causes the brush layer 53 to move vertically as well, ensuring that the brush layer 53 can continuously clean the fixed plate 43. In addition, when the shredded lizard medicinal material of the correct size moves from the sieve hole 44 to the through hole 42, the rotating brush layer can disperse the shredded lizard medicinal material, thus preventing the lizard medicinal material from piling up.

[0049] Since the liquid nitrogen tube 60 is fixed to the bottom of the partition plate 40, and the liquid nitrogen can flow continuously inside the liquid nitrogen tube 60, the heat generated during the pulverization process can be absorbed and carried away by the liquid nitrogen, thus ensuring that the lizard medicine can be pulverized at low temperature.

[0050] After being crushed and meeting size requirements, the lizard medicinal material moves downward through the sieve holes 44 and through holes 42, causing it to fall into the gap between two adjacent fan blades 62. This allows the crushed lizard medicinal material to enter the side hole 63 and come into contact with the liquid nitrogen tube 60, thereby removing excess heat from the crushed lizard medicinal material. The two adjacent fan blades 62 also act as a barrier, prolonging the contact time between the crushed lizard medicinal material and the liquid nitrogen tube 60, thus enhancing the heat absorption effect. Furthermore, the weight of the crushed lizard medicinal material compresses the fan blades 62, causing the sleeve 61 to rotate. The rotation of the fan blades 62 further disperses the lizard medicinal material, preventing it from piling up.

[0051] After being crushed and meeting the required size, the lizard medicinal material continues to move downwards. The output shaft of the second motor drives the grinding roller 70 to rotate, and the two grinding rollers 70 rotate in opposite directions, so that the lizard medicinal material is ground under the action of the two grinding rollers 70 to obtain medicinal material particles, which are discharged through the discharge port 12.

[0052] In this embodiment, a number of third crushing teeth 23 are fixedly connected to the side wall of the movable block 21. When the two movable blocks 21 are close together, the third crushing teeth 23 on the two movable blocks 21 are brought closer together. Some of the lizard medicine may be squeezed into the gap between the two movable blocks 21. The lizard medicine can be crushed by the third crushing teeth 23 on the two movable blocks 21, thereby improving the crushing efficiency.

[0054] Step 1: Place the lizard medicine into the box 10 through the feed inlet 11;

[0055] Step 2: Start the first motor 32 and the second motor to crush the lizard medicine inside the box 10; introduce liquid nitrogen into the liquid nitrogen pipe 60 to crush the lizard medicine at low temperature inside the box 10.
