Description

Technical Field

[0001] The utility model relates to the technical field of medicine washing machines, in particular to a medicine washing device. Background Art

[0002] The medicine washing machine adopts the integral rotary type. The feed port, discharge port and cylinder are all made of stainless steel plates and are equipped with a high-pressure water pump spray device. Tap water can be used for flushing. The material is pushed forward by the inner Luoxuan guide plate to implement continuous production and automatic discharge.

[0003] During the production and processing of medicinal materials, the medicinal materials need to be cleaned. Only after the impurities and dust on the medicinal materials are cleaned can they be used. This process involves the use of a medicine washing machine. The cleaning process of the existing medicine washing machine is to put the medicinal materials into the feeding port of the medicine washing machine, and driven by the conveying mechanism in the medicine washing machine, the medicinal materials are conveyed from the feeding port to the discharging port. During this process, the high-pressure water pump spray device in the medicine washing machine will spray and clean the medicinal materials on the conveying mechanism, and a certain volume of tap water will be stored in the medicine washing machine. The tap water will submerge the conveying mechanism, and the medicinal materials on the conveying mechanism will also be soaked in the tap water, that is, the medicinal materials will be soaked and sprayed and cleaned by the spray device until the cleaning of the medicinal materials is completed.

[0004] In the above-mentioned cleaning process of the medicinal materials, since the medicinal materials have different sizes, the medicinal materials of different sizes are not cleaned thoroughly during the cleaning process, that is, some medicinal materials will be blocked by other medicinal materials of different sizes, resulting in the high-pressure water pump spray device being unable to clean these medicinal materials. The medicinal materials are always soaked in tap water without being cleaned, which will make the cleaning of the medicinal materials inadequate and affect the use effect of the medicinal materials.

[0028] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0029] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0030] Example

[0031] like Figure 1 As shown, this embodiment provides a medicinal material cleaning device, comprising:

[0032] A water tank 1 is provided with a receiving chamber 2 at one end and a driving assembly at the other end; a cleaning cylinder 4 located between the receiving chamber 2 and the driving assembly is connected to the top of the water tank 1, and the cleaning cylinder 4 has a feed inlet 40 and a discharge port 41, and the discharge port 41 corresponds to the receiving chamber 2, and a cleaning assembly is provided on the inner wall of the cleaning cylinder 4;

[0033] The sieve drum group is located between the feed port 40 and the discharge port 41, and includes a first sieve drum 42, a second sieve drum 43 and a third sieve drum 44, the drum lengths and sieve hole diameters of which decrease successively. The second sieve drum 43 is rotatably connected to the outer wall of the first sieve drum 42, and the third sieve drum 44 is rotatably connected to the outer wall of the second sieve drum 43; a first gear 420 located on the outer side of the second sieve drum 43 is circumferentially provided on the outer wall of the first sieve drum 42; a second gear 430 located on the outer side of the third sieve drum 44 is circumferentially provided on the outer wall of the second sieve drum 43; a third gear 440 is circumferentially provided on the outer wall of the third sieve drum 44, and the first gear 420, the second gear 430 and the third gear 440 are all transmission-connected to the driving assembly, and the cleaning assembly is located inside the first sieve drum 42.

[0034] The feed chamber is located below the discharge port 41, and the cleaning assembly is connected to the external water inlet pipe 5. The cleaning assembly includes a water inlet pipe 5 and a spray head 6. The water inlet pipe 5 passes through the inside of the first sieve cylinder 42. There are multiple spray heads 6, all of which are connected to the water inlet pipe 5. The part of the water inlet pipe 5 located outside the cleaning cylinder 4 is connected to the external water outlet pipe 5. After the connection, the water inlet and outlet are controlled by the valve switch, and an air pump can also be added to increase the water outlet pressure to enhance the spray cleaning effect of the spray head 6 on the medicinal materials. The first sieve cylinder 42, the second sieve cylinder 43 and the third sieve cylinder 44 are level at one end close to the discharge port 41, and there is a fault between the other ends, that is, the cylinder lengths of each sieve cylinder are different.

[0035] When in use, the driving component drives the first sieve drum 42, the second sieve drum 43 and the third sieve drum 44 to rotate through the meshing transmission of the first gear 420, the second gear 430 and the third gear 440 respectively, and opens the valve connected to the cleaning component at the same time, and then puts the medicinal materials into the feed port 40. Under the cleaning of the cleaning component, the medicinal materials are cleaned, and due to the rotation of the sieve drum, the medicinal materials of different sizes can be screened through the sieve holes on the sieve drum into different sieve drums for cleaning. The medicinal materials located in the second sieve drum 43 are cleaned by the cleaning water flowing out of the first sieve drum 42, and the medicinal materials located in the third sieve drum 44 are cleaned by the cleaning water flowing out of the second sieve drum 43. After cleaning, the cleaned medicinal materials can be discharged from their respective sieve drums toward the discharge port 41. It is worth noting that since the cleaning component will continue to clean the medicinal materials, the cleaning water in the water tank 1 will gradually accumulate and increase. Therefore, it is necessary to provide a circulating water device that can extract and recycle the water in the water tank 1. Although the circulating water device is not described in detail in this application, most of the existing medicine washing machines are equipped with this device, and it is also a technology well known to those skilled in the art. Therefore, the circulating water device is not described in detail in this application.

[0036] Further, such as Figure 1 As shown, the driving assembly includes a box body 3, a motor 30, a first rotating rod 31, a second rotating rod 32 and a third rotating rod 33. The box body 3 is arranged on the outer wall of the water tank 1. A cavity 10 connected to the box body 3 is opened on the side wall of the water tank 1. The motor 30 is arranged inside the box body 3. The first rotating rod 31 is arranged on the output end of the motor 30. The first rotating rod 31 extends to the inside of the cavity 10. A first bevel gear 310 is circumferentially arranged on the outer side of the first rotating rod 31. The second rotating rod 32 is rotatably connected to the third rotating rod 33. Inside the cavity 10, a second bevel gear 320 and a third bevel gear 321 are respectively provided on the outer wall of the second rotating rod 32, and the first bevel gear 310 and the second bevel gear 320 are meshed with each other; the third rotating rod 33 is rotatably connected to the inner wall of the cleaning cylinder 4, and a fourth bevel gear 330 meshing with the third bevel gear 321 is provided on the outer wall of the third rotating rod 33, and a main gear 331 meshing with the first gear 420, the second gear 430 and the third gear 440 is also provided on the outer wall of the third rotating rod 33.

[0037] The cavity 10 is opened at one end of the side wall of the cleaning cylinder 4 away from the feed port 40. Since the third rotating rod 33 needs to be located at the top of the cleaning cylinder 4, the cavity 10 is not connected to the feed port 40. The box body 3 is located below the feed port 40. At the bottom of each screen cylinder and above the box body 3 is the position where the third rotating rod 33 extends from the cavity 10 in the side wall of the cleaning cylinder 4, that is, there are two third rotating rods 33 in this embodiment, which are distributed at both ends of the second rotating rod 32, so that there are two main gears 331 on the third rotating rod 33, which can achieve the transmission effect of each screen cylinder and also play a supporting role for each screen cylinder. When two third rotating rods 33 are used, the second bevel gear 320 on the second rotating rod 32, the third bevel gear 321 on the third rotating rod 33, the fourth bevel gear 330 and the main gear 331 are all increased accordingly.

[0038] When in use, the motor 30 in the box body 3 runs, and the output end of the motor 30 drives the first rotating rod 31 to rotate. The first rotating rod 31 is meshed with the first bevel gear 310 set on its own outer wall and the second bevel gear 320 on the second rotating rod 32, thereby driving the second rotating rod 32 to rotate. When the second rotating rod 32 rotates, the third bevel gear 321 at both ends can be meshed with the fourth bevel gear 330 on the third rotating rod 33 to drive the third rotating rod 33 to rotate. Finally, the rotation of the third rotating rod 33 drives each sieve drum to rotate through the main gear 331 set on its own outer wall that meshes with the first gear 420, the second gear 430 and the third gear 440, thereby completing the screening of medicinal materials.

[0039] Further, such as Figure 4 As shown, the height of the end of the screen drum group close to the feed port 40 above the ground is higher than the height of the end of the screen drum group close to the discharge port 41 above the ground.

[0040] When in use, the two ends of the sieve drum group are at different heights from the ground, so that the sieve drum group is arranged tilted as a whole, which facilitates the movement of medicinal materials in the sieve drum group.

[0041] Further, such as Figure 2-6 As shown, a support rod 45 is provided on the inner wall of the cleaning cylinder 4, a fixed plate 451 is provided on the outer wall of the support rod 45, a ring 450 is rotatably connected to the support rod 45, a through hole 452 for the ring 450 to pass through is opened on the fixed plate 451, a lever 453 and a connecting rod 455 are respectively provided on the outer wall of the ring 450, a striking block 456 is provided on the free end of the connecting rod 455, a spring 454 is connected between the lever 453 and the fixed plate 451, a fixed ring 332 is provided on the outer wall of the third rotating rod 33, and a lever block 333 which periodically contacts the lever 453 is provided on the outer wall of the fixed ring 332.

[0042] The support rod 45 is arranged on the inner wall of the cleaning cylinder 4 along the length direction of the cleaning cylinder 4, the fixing plate 451 is perpendicular to the tangent on the outer wall of the support rod 45, and the through hole 452 opened on the fixing plate 451 is located at the connection between the fixing plate 451 and the support rod 45. The through hole 452 can enable the rotatably connected ring 450 on the support rod 45 to rotate. The lever 453 is perpendicular to the tangent on the outer wall of the ring 450, and the spring 454 connects the lever 453 and the fixed plate 451. When the lever block 333 and the lever 453 go from contact to separation, the rotation direction of the connecting rod 455 is opposite to the rotation direction of the third rotating rod 33, and the spring 454 between the lever 453 and the fixed plate 451 is in a compressed state. After the lever block 333 and the lever 453 are separated from each other, the spring 454 will extend under the action of elastic force. At this time, the connecting rod 455 has the same rotation direction as the third rotating rod 33, so that the screen cylinder can be struck. It is worth noting that in order to avoid the situation where the screen holes of each screen cylinder are blocked, at least three striking blocks 456 can be set on the support rod 45 to complete the striking.

[0043] When in use, the third rotating rod 33 rotates, and the shifting block 333 on the fixed ring 332 is used to periodically abut the shifting rod 453, so that the shifting rod 453 drives the circular ring 450 to rotate on the support rod 45, and the shifting rod 453 squeezes the spring 454, and the circular ring 450 drives the connecting rod 455 to rotate, and the free end of the connecting rod 455 is separated from the contact with the sieve cylinder. When the shifting block 333 and the shifting rod 453 are separated from the contact, the squeezed spring 454 on the fixed plate 451 gives elastic force to the shifting rod 453, so that the shifting rod 453 rebounds, thereby achieving the goal of driving the striking block 456 on the connecting rod 455 to strike the sieve cylinder through the circular ring 450, thereby avoiding the situation where the medicinal materials are stuck in the sieve holes on the sieve cylinder. It is worth noting that there is a gap between the sieve holes on the sieve cylinder, and this gap is used for the striking block 456 to strike, that is, to prevent the striking block 456 from striking the sieve holes on the sieve cylinder to avoid damaging the medicinal materials and to avoid the striking block 456 from hitting the sieve holes and hindering the rotation of the sieve cylinder.

[0044] Further, such as Figure 7 As shown, blocks 7 are provided on the inner walls of the first sieve drum 42 , the second sieve drum 43 and the third sieve drum 44 . The blocks 7 are arranged along the length direction of the first sieve drum 42 , and one end of the blocks 7 close to the feed port 40 is inclined toward the rotation direction of the first sieve drum 42 .

[0045] There are multiple blocks 7, which are respectively arranged on the inner wall of the first sieve cylinder 42, the inner wall of the second sieve cylinder 43 and the inner wall of the third sieve cylinder 44, and are all arranged along the length direction of each sieve cylinder. In order to enable the medicinal materials to move better on the sieve cylinder, one end of each block 7 facing the feed port 40 is inclined toward the rotation direction of the respective sieve cylinder to prevent the blocks 7 in the sieve cylinder from being unable to discharge the medicinal materials from the sieve cylinder into the receiving chamber 2 when the sieve cylinder rotates. The blocks 7 can be cross-arranged to enable the medicinal materials to be discharged from the sieve cylinder.

[0046] When in use, each sieve drum rotates under the drive of the driving assembly, so that the medicinal materials in each sieve drum can be brought from the feed port 40 of the cleaning drum 4 to the discharge port 41 of the cleaning drum 4 by the obliquely arranged stopper 7 .

[0047] Further, such as Figure 5 As shown, the interior of the cleaning cylinder 4 is filled with cleaning water, and the liquid level of the cleaning water is located between the first sieve cylinder 42 and the second sieve cylinder 43 .

[0048] During use, since the cleaning cylinder 4 is connected to the water tank 1, the interior of the cleaning cylinder 4 will be filled with cleaning water, and the liquid level of the cleaning water in the cleaning cylinder 4 will be higher than the outer wall of the second sieve cylinder 43 close to one end of the first sieve cylinder 42, that is, when the second sieve cylinder 43 is running and rotating, the medicinal materials in the second sieve cylinder 43 can be immersed in the cleaning water for cleaning.

[0049] Further, such as Figure 5 As shown, an ultrasonic cleaning machine 34 is provided on the inner wall of the water tank 1 .

[0050] When in use, the ultrasonic cleaning machine 34 is located in the cleaning cylinder 4 and is soaked in cleaning water, which can vibrate and clean the medicinal materials in the second sieve cylinder 43 and the third sieve cylinder 44, so that the cleaning of the medicinal materials is more thorough.

[0051] Further, such as Figure 5 As shown, an opening is provided at the top of the cleaning cylinder 4, and a sealing cover is hingedly connected to the top of the cleaning cylinder 4 and is located on the opening.

[0052] When in use, the sealing cover can be opened at the top of the cleaning cylinder 4. After opening, the components inside the cleaning cylinder 4 can be repaired and replaced through the opening.

[0053] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
