Description

Technical Field

[0001] This utility model relates to the field of grinding and pulverizing technology, and in particular to a raw material grinding and pulverizing device. Background Technology

[0002] Oral liquid preparations are sterile or semi-sterile oral liquid formulations made from traditional Chinese medicine decoctions. These preparations are made by extracting the active ingredients from the herbs, adding flavoring agents, antibacterial agents, and other additives, and then filling them into injection ampoules using the same process. Therefore, they are also called oral ampoules. During the production of oral liquids, the raw materials of the traditional Chinese medicine herbs need to be processed by grinding them into small particles to facilitate subsequent liquid preparation.

[0003] However, the oral liquid raw material grinding and pulverizing devices in the relevant technologies still have shortcomings in use. They are not convenient for effectively pre-pulverizing Chinese medicinal materials, resulting in excessively large raw material blocks that affect the effect and efficiency of subsequent grinding. At the same time, it is inconvenient to adjust the grinding head according to the required degree of grinding, which reduces the effectiveness of use. Therefore, we propose a raw material grinding and pulverizing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a raw material grinding and pulverizing device.

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

[0006] A raw material grinding and pulverizing device includes a tank, a grinding trough fixedly connected inside the tank, a box fixedly connected to the top of the tank, a grinding head for grinding oral liquid raw materials disposed at the bottom of the box, the grinding head being movably disposed within the grinding trough, an adjustable grinding mechanism disposed between the grinding head and the box, a feed hopper fixedly connected to the top of the tank, a pre-pulverizing mechanism disposed between the feed hopper and the box, a scraping and cleaning mechanism disposed between the bottom of the box and the grinding head, and a discharge pipe fixedly connected to the bottom inner wall of the grinding trough, a solenoid valve disposed within the discharge pipe.

[0007] As a preferred embodiment of this utility model, the adjustable grinding mechanism includes a servo motor fixedly connected to the top of the housing and two cylinders fixedly connected to the inner wall of the bottom of the housing. A drive shaft is fixedly connected to the output shaft of the servo motor, and limit blocks are fixedly connected to both sides of the drive shaft. The same lifting plate is fixedly connected to the output shaft of the two cylinders, and a connecting shaft is rotatably connected to the bottom of the lifting plate. The bottom end of the connecting shaft is fixedly connected to the top of the grinding head.

[0008] As a preferred embodiment of this utility model, a scale rod is fixedly connected to the top of the lifting plate, and the top end of the scale rod extends to the top of the box body.

[0009] In a preferred embodiment of this invention, a bearing is fixedly sleeved inside the lifting plate, the connecting shaft is fixedly sleeved inside the inner ring of the bearing, and retaining rings are fixedly connected to the top and bottom of the lifting plate, with the bearing movably abutting between the two retaining rings.

[0010] As a preferred embodiment of this utility model, limit grooves are provided on both sides of the inner wall of the connecting shaft, and the limit block is slidably sleeved in the limit groove.

[0011] In a preferred embodiment of this utility model, the pre-crushing mechanism includes a drive bevel gear fixedly sleeved on the outside of the drive shaft and a rotating shaft rotatably connected to the inner walls on both sides of the feed hopper. A driven bevel gear is fixedly connected to one end of the rotating shaft. The drive bevel gear meshes with the driven bevel gear. Multiple crushing blades are connected to the outside of the rotating shaft.

[0012] As a preferred embodiment of this utility model, the scraping and cleaning mechanism includes two cylinders fixedly connected to the inner wall of the bottom of the box body. A compression spring is fixedly connected to the inner wall of the top of the cylinder. A vertical rod is fixedly connected to the bottom end of the compression spring. The same scraper is fixedly connected to the bottom end of the two vertical rods. The scraper is slidably sleeved on the outside of the connecting shaft.

[0013] As a preferred embodiment of this invention, the two vertical rods are slidably sleeved within their respective cylindrical bodies.

[0014] In this utility model, a raw material grinding and pulverizing device is described. The raw materials for oral liquid Chinese medicinal herbs to be ground and pulverized are poured into a feeding hopper. A servo motor drives the rotation of a drive shaft, which in turn drives the rotation of a drive bevel gear. The drive bevel gear, in turn, drives the rotation of a driven bevel gear, a rotating shaft, and a pulverizing blade. This process first pulverizes larger pieces of Chinese medicinal herbs into smaller pieces, facilitating subsequent grinding. The pre-pulverized smaller pieces fall into the gap between the grinding tank and the grinding head. The drive shaft then drives the rotation of a limiting block, a connecting shaft, and the grinding head, further grinding the smaller pieces within the gap, thus improving the grinding effect and efficiency.

[0015] In this utility model, a raw material grinding and pulverizing device is described. When the degree of grinding needs to be adjusted, two cylinders are activated. The cylinders drive the lifting plate and the connecting shaft to rise and fall, and the connecting shaft drives the grinding head to rise and fall. Thus, the gap between the grinding head and the grinding groove can be adjusted according to the different grinding requirements. Through the setting of the limiting block and the limiting groove, not only is the rising and falling of the connecting shaft not hindered, but also, when rotating, the drive shaft can drive the connecting shaft to rotate together. When adjusting the grinding head, the setting of the compression spring and the scraper can automatically drive the scraper to rise and fall, so that the scraper always abuts against the surface of the grinding head, which can scrape the Chinese herbal raw material particles attached to the grinding head into the pores for grinding, avoiding the situation where some parts are not ground.

[0016] This utility model has a reasonable structural design, which can pre-crush the raw materials of Chinese medicinal materials for oral liquids, making the raw material pieces smaller, which is conducive to subsequent grinding. The gap between the grinding head and the grinding tank can be adjusted according to the different grinding requirements to ensure the grinding effect and improve the practicality of the device. It also helps to scrape the raw material particles of Chinese medicinal materials attached to the grinding head into the pores for grinding, avoiding the situation where some parts are not ground.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A raw material grinding and pulverizing device includes a tank 1, a grinding trough 8 fixedly connected inside the tank 1, a box 2 fixedly connected to the top of the tank 1, a grinding head 7 for grinding oral liquid raw materials being provided at the bottom of the box 2, the grinding head 7 being movably disposed within the grinding trough 8, an adjustable grinding mechanism 4 being provided between the grinding head 7 and the box 2, a feed hopper 3 fixedly connected to the top of the tank 1, a pre-pulverizing mechanism 5 being provided between the feed hopper 3 and the box 2, a scraping and cleaning mechanism 6 being provided between the bottom of the box 2 and the grinding head 7, and a discharge pipe 9 fixedly connected to the inner wall of the bottom of the grinding trough 8, with a solenoid valve 91 provided inside the discharge pipe 9.

[0026] As a further part of this utility model, the adjustable grinding mechanism 4 includes a servo motor 41 fixedly connected to the top of the housing 2 and two cylinders 48 fixedly connected to the inner wall of the bottom of the housing 2. A drive shaft 43 is fixedly connected to the output shaft of the servo motor 41. Limit blocks 49 are fixedly connected to both sides of the drive shaft 43. The same lifting plate 47 is fixedly connected to the output shaft of the two cylinders 48. A connecting shaft 42 is rotatably connected to the bottom of the lifting plate 47. The bottom end of the connecting shaft 42 is fixedly connected to the top of the grinding head 7.

[0027] Using the above scheme: When it is necessary to adjust the degree of grinding, two cylinders 48 are activated. Cylinders 48 drive the lifting plate 47 and the connecting shaft 42 to rise and fall. The connecting shaft 42 drives the grinding head 7 to rise and fall, thereby adjusting the gap between the grinding head 7 and the grinding groove 8. The smaller the gap, the smaller the particles of Chinese medicinal materials ground, and vice versa. The servo motor 41 drives the drive shaft 43 to rotate, and the drive shaft 43 drives the limit block 49, the connecting shaft 42 and the grinding head 7 to rotate, thereby grinding smaller pieces of Chinese medicinal materials in the pores and improving the grinding effect and efficiency.

[0028] As a further feature of this invention, a scale rod 44 is fixedly connected to the top of the lifting plate 47. The top end of the scale rod 44 extends to the top of the housing 2. The size of the gap between the grinding head 7 and the grinding groove 8 can be precisely adjusted by means of the scale rod 44.

[0029] As a further feature of this invention, a bearing 45 is fixedly sleeved inside the lifting plate 47, and a connecting shaft 42 is fixedly sleeved inside the inner ring of the bearing 45. A retaining ring 46 is fixedly connected to both the top and bottom of the lifting plate 47, and the bearing 45 is movably abutted between the two retaining rings 46, which helps to support the connecting shaft 42 and make its rotation more stable. At the same time, it can limit the bearing 45 and prevent the connecting shaft 42 from detaching from the lifting plate 47.

[0030] As a further feature of this invention, limit grooves 40 are provided on both inner walls of the connecting shaft 42, and limit blocks 49 are slidably sleeved in the limit grooves 40. Through the setting of limit blocks 49 and limit grooves 40, not only is the lifting and lowering of the connecting shaft 42 not hindered, but also the driving shaft 43 can drive the connecting shaft 42 to rotate together when rotating.

[0031] As a further part of this utility model, the pre-crushing mechanism 5 includes an active bevel gear 54 fixedly sleeved on the outside of the drive shaft 43 and a rotating shaft 51 rotatably connected to the inner walls on both sides of the feed hopper 3. One end of the rotating shaft 51 is fixedly connected to a driven bevel gear 53. The active bevel gear 54 meshes with the driven bevel gear 53. A plurality of crushing blades 52 are connected to the outside of the rotating shaft 51.

[0032] The above scheme is adopted: the drive shaft 43 drives the rotation of the active bevel gear 54, which in turn drives the rotation of the driven bevel gear 53, the rotating shaft 51, and the pulverizing blade 52. This allows larger pieces of Chinese medicinal materials to be pulverized into smaller pieces, which facilitates grinding. The pre-pulverized smaller pieces of Chinese medicinal materials fall into the gap between the grinding tank 8 and the grinding head 7. The drive shaft 43 drives the rotation of the limiting block 49, the connecting shaft 42, and the grinding head 7, thereby grinding the smaller pieces of Chinese medicinal materials in the gap and improving the grinding effect and efficiency.

[0033] As a further feature of this invention, the scraping and cleaning mechanism 6 includes two cylinders 61 fixedly connected to the inner wall of the bottom of the housing 2. A compression spring 64 is fixedly connected to the inner wall of the top of the cylinder 61. A vertical rod 62 is fixedly connected to the bottom end of the compression spring 64. The same scraper 63 is fixedly connected to the bottom end of the two vertical rods 62. The scraper 63 is slidably sleeved on the outside of the connecting shaft 42.

[0034] The above solution is adopted: when adjusting the grinding head 7, the scraper 63 can be automatically driven to rise and fall by the setting of the compression spring 64 and the scraper 63, so that the scraper 63 always abuts against the surface of the grinding head 7, and scrapes the Chinese herbal raw material particles attached to the grinding head 7 into the pores for grinding, avoiding the situation where some parts are not ground.

[0035] As a further feature of this invention, the two vertical rods 62 are slidably sleeved inside the corresponding cylinders 61, which facilitates the guidance of the vertical rods 62 and makes their movement more stable and smooth.

[0036] In this invention, during operation, the raw materials of oral liquid Chinese medicinal herbs to be ground and pulverized are poured into the feed hopper 3. The servo motor 41 drives the rotation of the drive shaft 43, which in turn drives the rotation of the active bevel gear 54. The active bevel gear 54 drives the rotation of the driven bevel gear 53, the rotating shaft 51, and the pulverizing blade 52. This process first pulverizes larger pieces of Chinese medicinal herbs into smaller pieces, facilitating subsequent grinding. The pre-pulverized smaller pieces of Chinese medicinal herbs fall into the gap between the grinding tank 8 and the grinding head 7. The drive shaft 43 drives the rotation of the limiting block 49, the connecting shaft 42, and the grinding head 7, thereby grinding the smaller pieces of Chinese medicinal herbs in the gap and improving the grinding effect and efficiency.

[0037] When the grinding intensity needs to be adjusted, two cylinders 48 are activated. Cylinders 48 drive the lifting plate 47 and connecting shaft 42 to rise and fall. Connecting shaft 42 drives the grinding head 7 to rise and fall, thereby adjusting the gap between the grinding head 7 and the grinding groove 8. The smaller the gap, the smaller the particles of the ground Chinese medicinal materials, and vice versa. The setting of the limiting block 49 and the limiting groove 40 not only does not hinder the rising and falling of the connecting shaft 42, but also allows the drive shaft 43 to drive the connecting shaft 42 to rotate together when rotating. When adjusting the grinding head 7, the setting of the compression spring 64 and the scraper 63 can automatically drive the scraper 63 to rise and fall, so that the scraper 63 always abuts against the surface of the grinding head 7, which can scrape the particles of Chinese medicinal materials attached to the grinding head 7 into the pores for grinding, avoiding the situation where some parts are not ground.
