Description

Technical Field

[0001] The invention belongs to the technical field of roller grinding and relates to a powder grinding device for processing Chinese herbal medicine slices. Background Art

[0002] Chinese herbal medicine slices are prepared according to TCM theory and methods, ready for direct use in TCM clinical practice. This concept suggests that there's no absolute distinction between Chinese herbal medicines and herbal slices. These slices encompass slices of some processed herbs from their origin, slices of the original herbal material, and slices that have been cut and processed.

[0003] In the use of Chinese herbal medicines, some of them need to be soaked before drinking, but some of them are too large and it is troublesome to soak them, so they need to be processed into powder and then soaked. However, in the process of processing Chinese herbal medicines into powder, they are usually crushed by a grinder, but the speed of the grinder is too fast, which will generate a lot of heat, and the medicinal properties of some Chinese herbal medicines will change after they are heated, so grinding is also used to grind the Chinese herbal medicines. However, when adding Chinese herbal medicines during the grinding process, the Chinese herbal medicines will be added into the groove and ground by a grinding wheel. However, when adding, it is easy to cause the Chinese herbal medicines to stack, and it is difficult to push the Chinese herbal medicines evenly, which affects the grinding effect.

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings and examples.

[0032] A powder grinding device for processing Chinese herbal medicine slices, such as Figure 1-Figure 7 As shown, it includes a base 1, a supporting tray 2, a rotating shaft 31, a driving motor 32, a rotating ring 3, a crushing roller 4, a scraping mechanism and a leveling mechanism. The top of the base 1 is connected to the supporting tray 2, and the driving motor 32 is installed in the middle of the bottom of the base 1. The output shaft of the driving motor 32 is connected to the rotating shaft 31, and the rotating shaft 31 passes through the middle position of the supporting tray 2. The top of the rotating shaft 31 is connected to the rotating ring 3, and the crushing roller 4 is connected to the rotating ring 3 for rotation. The crushing roller 4 is in contact with the bottom of the supporting tray 2. The rotating ring 3 is provided with a scraping mechanism for scraping off the powder attached to the crushing roller 4 and a leveling mechanism for leveling the powder on the supporting tray 2.

[0033] like Figure 2 and Figure 5 As shown, the scraper mechanism includes a guide rail 51, a scraper frame 52 and an elastic member 53. The guide rail 51 is connected to the rotating ring 3, and the scraper frame 52 is slidably connected to the guide rail 51. The scraper frame 52 can move to fit with the rolling roller 4 so that the rolling roller 4 rotates and the scraper frame 52 can scrape off the powder attached to the rolling roller 4. An elastic member 53 is connected between the scraper frame 52 and the guide rail 51, and the elastic member 53 is a compression spring.

[0034] like Figure 6-Figure 7The bottom of the adjusting screw 66 contacts the top of the squeezing bracket 62, and the bottom of the scraper plate 65 is evenly spaced with forming grooves to form a ridge when the powder is swept, which is convenient for the rolling operation of the rolling roller 4.

[0035] When it is necessary to grind the Chinese herbal medicine slices into powder, the grinding device can be used. When in use, the Chinese herbal medicine slices are first poured into the support tray 2, and then the driving motor 32 is controlled to drive the rotating shaft 31 and the rotating ring 3 to rotate. The rotating ring 3 drives the grinding roller 4 to rotate when rotating. The grinding roller 4 rotates at the support tray 2 and rubs against the support tray 2 and then rotates on its own, thereby grinding the Chinese herbal medicine slices at the support tray 2. When the rotating ring 3 rotates, it can also drive the scraper 65 to rotate, thereby scraping the slices at the support tray 2 flat and grinding them into powder. After the powder is formed, the powdered medicinal slices can also be scraped flat, and after being scraped flat, the powder can be raised through the forming groove to facilitate the subsequent rolling operation of the rolling roller 4. This is repeated to achieve the rolling work of the medicinal powder, and when rolling, the medicinal powder can be scraped flat and the medicinal powder part can be raised for rolling, which is beneficial to the overall rolling work. In the actual operation process, the adjusting screw 66 can be moved up and down by rotating the adjusting screw 66 so that the bottom end of the adjusting screw 66 is against the extrusion bracket 62, thereby To drive the sliding frame 64 and the scraper 65 to move up and down, so as to adjust the upper and lower positions of the sliding frame 64 and the scraper 65, it is convenient to adjust the adding amount of Chinese medicine decoction piece powder. After the crushing is completed, the extrusion bracket 62 can be pulled to move to the right. At this time, the extrusion bracket 62 no longer supports the adjusting screw 66. Under the action of gravity, the adjusting screw 66 moves down, and the sliding frame 64 and the scraper 65 also move down. After the scraper 65 moves down, it abuts against the bottom of the supporting tray 2. At this time, the scraper 65 continues to move. Continuous rotation can scrape the crushed powder together to gather the powder for subsequent collection and processing. After a large amount of powder is attached to the crushing roller 4, the scraper frame 52 can be pulled to fit the crushing roller 4, and the elastic member 53 is compressed. Then, during the rotation of the crushing roller 4, the powder attached to the crushing roller 4 can be scraped off by the scraper frame 52. After scraping, the crushing roller 4 is released, and the scraper frame 52 of the elastic member 53 is reset, thereby scraping off the powder attached to the crushing roller 4.

[0036] like Figure 8 As shown, it also includes a driving mechanism, which includes a cylinder 621 and a connecting plate 622. The cylinder 621 is installed on the top of the guide sleeve 61, and the connecting plate 622 is connected to the telescopic rod of the cylinder 621. The connecting plate 622 is connected to the left side of the extrusion bracket 62. An L-shaped protrusion is provided on the upper front side of the scraper frame 52, and the upper part of the L-shaped protrusion is located above the extrusion bracket 62 and at the moving track of the connecting plate 622.

[0037] Initially, the telescopic rod of the cylinder 621 is in an extended state. When it is necessary to control the extrusion bracket 62 to move to the right, the telescopic rod of the cylinder 621 can be controlled to retract to drive the connecting plate 622 to move to the right. When the connecting plate 622 moves to the right, it can drive the extrusion bracket 62 to move to the right. In the process of moving to the right, the connecting plate 622 will also cooperate with the L-shaped protrusion of the scraper frame 52 and drive the scraper plate 65 to move to the right. In this way, the effect of automatically driving the extrusion bracket 62 and the scraper plate 65 to move to the right can be achieved.

[0038] like Figure 9 and Figure 10 When the cam 72 is in the unlock position, the locking cam 73 is in the unlock position, and the locking cam 73 is in the unlock position, so that the locking cam 73 is unlocked.

[0039] When the extrusion bracket 62 moves to the right, it can push the moving rod 71 to move to the right, the elastic member 2 72 is compressed, and the moving rod 71 moves to the right, driving the wedge-shaped extrusion block 74 to move to the right. When the wedge-shaped extrusion block 74 moves to the right, it can squeeze the filling plate 75 to move downward. The elastic member 3 76 is compressed, and the filling plate 75 can fill the forming groove after moving downward. Subsequently, when scraping, all the powder can be scraped together to avoid powder residue caused by the forming groove.

[0040] like Figure 11 and Figure 12As shown, it also includes a collecting mechanism, which includes an electric guide rail 81, a conical guide plate 82, a drop hopper 83, a plug plate 84 and a sweeping plate 95. The electric guide rails 81 are installed on the front and back sides of the top of the base 1, and a conical guide plate 82 is connected between the moving bodies of the two electric guide rails 81. The conical guide plate 82 is sleeved on the outside of the rotating shaft 31, and the drop hopper 83 is connected to the conical guide plate 82. A plurality of plug plates 84 are evenly spaced in the drop hopper 83. Drop troughs are evenly spaced on the material support tray 2, and the number of the drop troughs is consistent with the number of the plug plates 84. The plug plate 84 can block the drop trough when it moves up. A sweeping plate 95 is slidably connected to the rotating shaft 31, and the sweeping plate 95 fits the inner wall of the drop hopper 83.

[0041] Initially, the plug plate 84 blocks the material chute, and the powder grinding operation can be carried out at this time. After the powder grinding is completed, the conical guide plate 82 can be driven downward by the electric guide rail 81, so that the plug plate 84 no longer fills the material chute. At this time, the scraper plate 65 scrapes the material and discharges the powder to the conical guide plate 82 through the material chute. Then, during the rotation of the rotating shaft 31, it can also drive the sweeping plate 95 to rotate, thereby sweeping the powder to the material hopper 83, and discharging the powder through the material hopper 83. In this way, it is convenient to collect the powder.

[0042] like Figure 1 As shown, a protective mechanism is also included, which includes a protective cover 9 and a cover plate 10. The top of the supporting tray 2 is connected to a protective cover 9 for protecting the supporting tray 2. The left side of the top of the protective cover 9 is rotatably connected to the cover plate 10. When the cover plate 10 is opened, Chinese herbal medicine slices can be added to the supporting tray 2, and the protective cover 9 can protect the supporting tray 2.

[0043] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
