Description

Technical Field

[0001] The utility model relates to the technical field of matcha grinding, in particular to a grinding device for making matcha. Background Technique

[0002] Matcha originated in the Sui and Tang dynasties of China. After the tea leaves are processed, they need to be ground into powder, then poured into a tea bowl and boiled water is poured in. After the foam is produced, it can be drunk. The traditional way to make matcha is to grind the tea leaves manually.

[0003] The traditional grinding method uses a stone mill for grinding. In recent years, in order to improve the grinding efficiency, air flow type, ball mill type, knife hammer type, etc. are adopted. However, the grinding effect of the stone mill is still better, and the price of matcha ground by the stone mill is several times that of other methods. In order to prevent material jamming, the existing stone mill grinding uses manual feeding, and the efficiency is very slow. Secondly, the ground powder adheres to the circumference of the stone mill, which is inconvenient for collection. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Example 1

[0025] As shown in the attached Figure 1 to the attached Figure 3 shown, a grinding device for making matcha includes a bracket 1 and a stone mill assembly 2 mounted thereon. The stone mill assembly 2 includes a first stone mill 3. A second stone mill 4 is provided below the first stone mill 3. The first stone mill 3 is rotatably connected to the second stone mill 4. A funnel 5 is provided near the edge of the first stone mill 3. The funnel 5 can always catch the tea leaves falling from the feeding port during rotation. The funnel 5 cooperates with a through hole 6 on the first stone mill 3. A first gear 7 is provided in the middle of the first stone mill 3. The first gear 7 meshes with a second gear 8 installed in the bracket 1. A driving shaft 9 is provided at the axis of the second gear 8. A scraper 10 is provided outside the first stone mill 3. The top end of the scraper 10 is provided on the upper side of the first stone mill 3, and the bottom end contacts a guiding ring 11. The guiding ring 11 is provided on the outer ring of the second stone mill 4. The guiding ring 11 is provided on the second stone mill 4, near the joint of the first stone mill 3 and the second stone mill 4. Its shape is an annular shape with a notch and a baffle outside. A receiving port 19 is provided at the notch. The receiving port 19 is in a slope shape. An upper feeding assembly 12 is provided on the upper side of the stone mill assembly 2.

[0026] With the above structure, pour tea leaves into the upper feeding assembly 12. The tea leaves enter the funnel 5. The funnel 5 is the same as the through hole 6 on the first stone mill 3 and enters the first stone mill 3. The second motor installed on the driving shaft 9 drives the second gear 8 to rotate. The first gear 7 meshing with the second gear 8 rotates, driving the first stone mill 3 to rotate and grind the tea leaves. The ground powder flows out from the gap between the first stone mill 3 and the second stone mill 4 and falls on the guiding ring 11. Under the action of the scraper 10, the powder attached to the guiding ring 11 and the grinding disc is sent to the receiving port 19.

[0027] Example 2

[0028] On the basis of Example 1, as shown in the attached Figure 1 , the attached Figure 2 and the attached Figure 4 shown, the upper feeding assembly 12 includes a fixed column 13 provided on the bracket 1. One end of a support frame 14 is connected to the fixed column 13. A cam 15 is rotatably connected to the support frame 14. The other end of the support frame 14 is slidably connected to a blocking shaft 16. The lower end of the blocking shaft 16 is the same size as the feeding port of the material bin 18 and blocks the feeding port in the normal state and opens the feeding port when lifted. A protruding plate 17 on the upper side of the blocking shaft 16 cooperates with the cam 15. The lower side of the support frame 14 is connected to the material bin 18.

[0029] With the above structure, a first motor is connected to the cam 15 to make it operate. When the cam 15 rotates, the protruding plate 17 on the upper side of the stop shaft 16 is affected by the cam 15, and the stop shaft 16 slides along the support frame 14, lifting or lowering the stop shaft 16. The lower end of the stop shaft 16 has the same size as the material discharge opening of the silo 18. When the stop shaft 16 is lowered, the material discharge opening is blocked and no material can be discharged at this time. When the stop shaft 16 is lifted, the material discharge opening is opened, and the tea leaves fall into the funnel 5, for intermittent feeding to prevent overfeeding at one time and causing material blockage.

[0030] The specific usage method is as follows: During use, pour the tea leaves to be ground into the silo 18. The first motor connected to the cam 15 makes it move intermittently, controlling the up and down movement of the stop shaft 16 to open or block the material discharge opening, realizing intermittent feeding. The tea leaves fall to the stone mill assembly 2. The second motor makes the first stone mill rotate through the way of driving gear rotation and meshing to grind the tea leaves. The ground powder accumulates at the material receiving port 19 under the action of the scraper 10, which is convenient for collection.

[0031] The first motor and the second motor body are not drawn in the attached drawings of this application, only the cam 15 and the drive shaft 9 are shown. The first motor and the second motor body are both conventional prior arts and will not be described in detail in this application.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
