Description

Technical Field

[0001] This invention relates to the field of natural mite-removing products, specifically to a type of mugwort mite-removing granules, preparation equipment, and method. Background Technology

[0002] With the popularization of healthy home concepts, natural, non-toxic, and long-lasting mite-removing products have become the mainstream in the market. Artemisia contains active ingredients such as eucalyptol and thujone, possessing natural mite-removing and antibacterial effects; attapulgite clay, due to its unique layered structure and strong adsorption properties, can serve as a carrier to load mite-removing ingredients, extending its effectiveness; the volatile oil components in peppermint, perilla, and Sichuan pepper can synergistically enhance mite-removing activity and are harmless to humans and the environment. Mite-removing granules prepared from these composite materials have significant application advantages.

[0003] For example, Chinese Patent Publication No. CN220194792U discloses an artemisia argyi granulator. Although it has disinfection and screening functions, it is only suitable for granulating a single artemisia argyi raw material. It cannot meet the crushing requirements of convex clay sticks, and it does not consider the low-temperature extraction and precise mixing of multi-component plant additives, making it difficult to meet the preparation requirements of composite mite-removing granules. Summary of the Invention

[0004] The purpose of this invention is to provide mugwort mite-removing granules, preparation equipment, and method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0018] Symmetrical sieving cylinders are used to sieve attapulgite clay powder, and pulverized perilla, mint, stemona, and Sichuan pepper are also sieved to ensure that the powder entering the mixing chamber meets the requirements for making mugwort mite-removing granules. A clockwise rotating drive rod and stirring rod stir the powder in the mixing chamber. During the stirring process, a baffle continuously seals the feed chute to prevent unmixed powders from entering the screw extruder. After mixing, a counter-clockwise rotating circular plate drives the T-shaped rod and support block away from the bottom of the baffle, releasing the baffle from the feed chute. The stirring rod then pushes the mixed powder through the feed chute into the screw extruder, completing the production of mugwort mite-removing granules. The direct feeding of the mixed powder into the screw extruder reduces dust generation in the production environment and improves the production efficiency of mugwort mite-removing granules.

Detailed Implementation

[0032] Please see Figure 1-3In this embodiment of the invention, a type of mugwort mite-removing granules, by weight percentage, comprises: 35% attapulgite clay powder and 20% mugwort powder as base materials; 10% perilla, 10% mint, 15% stemona, and 15% Sichuan pepper as excipients; based on 100 parts of the total weight of base and excipient materials, the auxiliary agents are 2-4 parts sodium carboxymethyl cellulose, 0.5-0.8 parts potassium sorbate, and 6-12 parts deionized water.

[0033] Artemisia powder is a 40-60 mesh low-temperature ground powder with an active ingredient content ≥1.2%; attapulgite clay powder is a 100-120 mesh graded pulverized powder with a specific surface area ≥850m² / g; perilla, mint, Stemona, and Sichuan pepper are 80-100 mesh low-temperature ground powders, with Stemona undergoing pretreatment to remove the xylem, and the total content of the four active ingredients (including Stemona alkaloid) is ≥0.9%; the finished product has a particle size of 1mm-5cm, a moisture content ≤8%, and a mite removal rate ≥99.5%.

[0034] Please see Figure 1-3 A device for preparing mugwort mite-removing granules includes a shell 1. A symmetrical screening cylinder 2 is fixedly connected to the upper end of the shell 1. A drive rod 4 is rotatably connected to the middle of the shell 1. A mixing chamber 18 is opened in the lower part of the shell 1. A drive mechanism for driving the drive rod 4 to rotate is set in the middle of the upper end of the shell 1. A bottom plate 21 is fixedly connected to the bottom of the inner cavity of the mixing chamber 18. A symmetrical feeding trough 23 is opened at the upper end of the bottom plate 21. A baffle 22 is rotatably connected to the inner cavity of the feeding trough 23. When the drive rod 4 rotates clockwise, the top of the baffle 22 fits against the top of the bottom plate 21. When the drive rod 4 rotates counterclockwise, the baffle 22 rotates downward toward the center of the drive rod 4.

[0035] Please see Figure 1-4A transmission rod 9 is rotatably connected to the upper middle part of the screening cylinder 2. The driving mechanism includes a servo motor 5, which is fixedly connected to the housing 1 via a mounting plate. The output end of the servo motor 5 is fixedly connected to the top of the drive rod 4. A drive gear 6 is fixedly connected to the upper outer wall of the drive rod 4, and a transmission gear 7 is fixedly connected to the upper outer wall of the transmission rod 9. The drive gear 6 and the transmission gear 7 mesh with each other. When the servo motor 5 drives the drive rod 4 to rotate, the drive gear 6 will drive the symmetrical transmission gear 7 to rotate synchronously, thereby driving the symmetrical transmission rod 9 to rotate simultaneously. The feeding port is fixedly connected to the side away from the drive gear 6. The lower part of the inner cavity of the screening cylinder 2 is fixedly connected to the screen 10. The lower part of the transmission rod 9 on one side is fixedly connected to the crushing blade 12, and the lower part of the transmission rod 9 on the other side is fixedly connected to the pusher plate 17. Attapulgite clay powder is added to the inner cavity of the screening cylinder 2 with the pusher plate 17, and the attapulgite clay powder is screened by the cooperation of the pusher plate 17 and the screen 10. Perilla, mint, stemona, and Sichuan pepper are added to another screening cylinder 2, and the perilla, mint, stemona, and Sichuan pepper are crushed and ground by the crusher 12, and screened by the screen 10 in the same way.

[0036] Please see Figure 4 A symmetrical round rod 13 is rotatably connected to the lower outer wall of the transmission rod 9. Brush bristles 14 are fixedly connected to the outer wall of the round rod 13. An annular groove 11 is formed in the lower part of the inner cavity of the screening cylinder 2. A ring plate is rotatably connected to the symmetrical round rods 13, sealing the annular groove 11. A ring rack 16 is fixedly connected to the bottom of the inner cavity of the annular groove 11. A driven gear 15 is fixedly connected to the end of the round rod 13 away from the transmission rod 9. The driven gear 15 and the ring rack 16 mesh with each other. Therefore, when the transmission rod 9 drives the round rod 13 to rotate horizontally, the engagement of the driven gear 15 and the ring rack 16 drives the round rod 13 axially in sync. The rotation causes the bristles 14 to rotate axially. At this time, the rotating bristles 14 continuously contact the lower end face of the screen 10, cleaning and unblocking the screen holes of the screen 10, thereby promoting the screening effect of the screen 10. The top of the inner cavity of the annular groove 11 is fixedly connected with symmetrical elastic plates. The driven gear 15 will continuously contact the elastic plates during horizontal rotation, thereby generating vibration through the elastic plates, further promoting the screening effect of the screen 10. The screened attapulgite clay powder, as well as the ground perilla, mint, stemona, and green pepper powder, enter the inner cavity of the mixing chamber 18 through the bottom of the screening cylinder 2.

[0037] Please see Figure 5-7The lower end of the drive rod 4 is fixedly connected to symmetrical stirring rods 19, which are located inside the mixing chamber 18. A mugwort powder inlet is fixedly connected to the upper side of the mixing chamber 18, allowing mugwort powder, attapulgite clay powder, and powders of perilla, mint, stemona, and Sichuan pepper to be simultaneously located within the mixing chamber 18. As the drive rod 4 rotates continuously, the stirring rods 19 mix and stir the powders within the mixing chamber 18, ensuring a uniform mixture. A conical block 20 is fixedly connected to the middle of the lower end of the drive rod 4, with the lower end face of the conical block 20 touching the bottom plate. The upper surfaces of 21 are in contact with each other, the diameter of the lower surface of the conical block 20 is larger than the interval between the symmetrical feeding grooves 23, the lower end of the stirring rod 19 is in contact with the outer wall of the conical block 20 on the side near the drive rod 4, the lower end of the housing 1 is fixedly connected to the feeding cylinder 3, and the lower end of the feeding cylinder 3 is fixedly connected to the screw extruder 8. The mixed powder enters the screw extruder 8 through the inner cavity of the feeding cylinder 3, and then the mixed powder is extruded into strips by the screw extruder 8 and cut into granules by the rotating blades. The screw extruder 8 and the rotating blades are both commonly used technical means in the prior art.

[0038] Please see Figure 6-10 The feed chute 23 is blocked by the baffle 22 to prevent powder from entering the feed cylinder 3 before it is mixed. The lower end of the drive rod 4 passes through the middle of the base plate 21 and is fixedly connected to a circular plate 24. The top of the circular plate 24 is lower than the lower end face of the base plate 21. Symmetrical T-shaped rods 25 are attached to the upper end face of the circular plate 24. The top of the T-shaped rods 25 is slidably connected to the lower end face of the base plate 21. The top of the T-shaped rods 25 is attached to the lower end face of the baffle 22. An outer ring groove 34 and an inner ring groove 35 are formed at the upper end of the circular plate 24. The diameter of the inner ring groove 35 is smaller than the diameter of the outer ring groove 34. A groove about the center of the circular plate 24 is formed between the outer ring groove 34 and the inner ring groove 35. A centrally symmetrical guide groove 36 connects the outer ring groove 34 and the inner ring groove 35. Guide block 1 37 and guide block 2 38 are respectively provided at the connection points of the two ends of the guide groove 36 with the outer ring groove 34 and the inner ring groove 35. Guide block 1 37 is located in the inner cavity of the outer ring groove 34, and guide block 2 38 is located in the inner cavity of the inner ring groove 35. A first inclined surface is opened on the side of guide block 1 37 away from the guide groove 36, and a second inclined surface is opened on the side of guide block 2 38 away from the guide groove 36. A guide rod 39 is fixedly connected to the middle of the lower end of the T-shaped rod 25. The outer wall of the lower end of the guide rod 39 slides in cooperation with the outer ring groove 34, the inner ring groove 35, and the guide groove 36.

[0039] Please see Figure 9-11Both guide block 37 and guide block 38 have grooves 40 below them. Guide block 37 and guide block 38 are vertically slidably connected in the grooves 40. The bottom of the inner cavity of the groove 40 is elastically connected to guide block 37 and guide block 38 by springs. When the guide rod 39 is in the inner cavity of the outer ring groove 34, the baffle 22 is in the inner cavity of the feeding groove 23 and blocks the feeding groove 23. When the drive rod 4 drives the circular plate 24 to rotate clockwise, the circular plate 24 drives the outer ring groove 34 and guide block 38 to rotate clockwise. As the guide rod 39 rotates clockwise continuously, its lower end will continuously contact the first inclined surface on the guide block 37. After contacting the first inclined surface, the guide rod 39 will press the guide block 37 into the inner cavity of the groove 40, causing the guide block 37 to retract into the inner cavity of the groove 40. After the guide rod 39 separates from the guide block 37, the guide block 37 will pop out of the inner cavity of the groove 40 again. Therefore, during the clockwise rotation of the circular plate 24, the guide rod 39 will remain in the inner cavity of the outer ring groove 34.

[0040] When the circular plate 24 rotates counterclockwise, the lower end of the guide rod 39 contacts the side of the guide block 37 away from the first inclined surface. Guided by the guide block 37, it enters the guide groove 36 and then the inner cavity of the inner ring groove 35. This causes the T-shaped rod 25 to move horizontally towards the center of the drive rod 4, causing the T-shaped rod 25 to lose its support for the baffle 22. Under the influence of gravity, the baffle 22 rotates downwards and contacts the blockage of the feeding chute 23, thus opening the inner cavity of the mixing chamber 18. After being mixed, the powder enters the feed cylinder 3 through the feed chute 23 and is finally extruded into shape in the inner cavity of the screw extruder 8. When the guide rod 39 is located in the inner cavity of the inner ring groove 35 and the circular plate 24 rotates counterclockwise, the lower end of the guide rod 39 will continuously contact the first inclined surface of the guide block 38. At this time, the guide block 38 will not guide the position of the guide rod 39, that is, the guide rod 39 will remain in the inner cavity of the inner ring groove 35, thereby keeping the baffle 22 away from the feed chute 23.

[0041] At this time, the drive rod 4 drives the stirring rod 19 to rotate counterclockwise, and the lower end face of the stirring rod 19 is in contact with the upper end face of the bottom plate 21. Then, the stirring rod 19 will push the mixed powder toward the position of the feeding trough 23, thereby promoting the powder to be removed from the mixing chamber 18 and improving the preparation efficiency of the mugwort mite-removing granules. After all the powder has been removed from the inner cavity of the mixing chamber 18, the drive rod 4 drives the circular plate 24 to rotate clockwise again. At this time, under the guidance of the guide block 38, the guide rod 39 will return from the inner cavity of the inner ring groove 35 to the inner cavity of the outer ring groove 34, thereby driving the baffle 22 to seal the feeding trough 23 again, so as to facilitate the mixing of the powder in the inner cavity of the mixing chamber 18 next time.

[0042] A symmetrical connecting rod 26 is fixedly connected to the end of the T-shaped rod 25 away from the driving rod 4. A driven plate 27 is fixedly connected to the end of the connecting rod 26 away from the T-shaped rod 25. The upper surface of the driven plate 27 is lower than the upper surface of the connecting rod 26. Support blocks 30 are slidably connected to both sides of the lower end of the feeding trough 23. A T-shaped block 31 is fixedly connected to the upper part of the support block 30 away from the feeding trough 23. A T-shaped groove 32 is opened at the lower end of the bottom plate 21. The T-shaped block 31 is slidably connected in the inner cavity of the T-shaped groove 32. The inner cavity sidewall of the T-shaped groove 32 and the T-shaped block 31 are elastically connected by a spring. A driven rod 33 is fixedly connected to the lower end of the support block 30. An inclined groove 28 is opened on the upper end of the driven plate 27 near the connecting rod 26. The inclined groove 28 is far from the driving rod 25. A horizontal groove 29 is provided on one side away from the connecting rod 26. The side of the driven rod 33 away from the support block 30 is slidably engaged with the inclined groove 28 and the horizontal groove 29. When the T-shaped rod 25 drives the connecting rod 26 and the driven plate 27 to move horizontally closer to the center of the driving rod 4, the sliding engagement between the inclined groove 28 and the driven rod 33 drives the support block 30 away from the center of the feed chute 23, thereby releasing the support of the support block 30 on the baffle 22. The support block 30 will separate from the bottom of the baffle 22 before the T-shaped rod 25. After the T-shaped rod 25 is completely separated from the baffle 22, the driven rod 33 separates from the horizontal groove 29. Under the action of the spring, the support block 30 remains in a state away from the center of the feed chute 23.

[0043] Please see Figure 9-12 During the resetting process of T-shaped rod 25, connecting rod 26 and driven plate 27, T-shaped rod 25 will contact the bottom of baffle 22 before support block 30, and T-shaped rod 25 will push baffle 22 to rotate toward the inner cavity of feed chute 23, thereby sealing feed chute 23 through baffle 22. During the resetting process of T-shaped rod 25, driven rod 33 will enter the inner cavity of horizontal groove 29, and with the resetting of T-shaped rod 25 and driven plate 27, driven rod 33 will enter inclined groove 28 and push support block 30 close to the lower end face of baffle 22. Then, the bottom of baffle 22 will be supported synchronously by symmetrical support block 30 and T-shaped rod 25, thereby providing stable support for baffle 22 and making baffle 22 stably seal feed chute 23.

[0044] A method for preparing Artemisia argyi anti-mite granules includes the following steps:

[0045] The symmetrical screening cylinder 2 is used to crush and screen attapulgite clay powder, as well as perilla, mint, stemona, and Sichuan pepper powder. The attapulgite clay powder, artemisia powder, perilla, mint, stemona, and Sichuan pepper powder are stirred and mixed in the mixing chamber 18 by the clockwise rotating stirring rod 19. After the powders are mixed, the drive rod 4 rotates counterclockwise to drive the T-shaped rod 25 and the support block 30 to move away from the baffle 22. The mixed powder is then fed into the screw extruder 8 through the feeding trough 23 and the inner cavity of the feeding cylinder 3 and extruded into shape.
