Description

Technical Field

[0001] The invention relates to the technical field of tea leaf grinding, in particular to a dry tea leaf grinding device. Background Art

[0002] Tea is a widely consumed beverage in the world. The grinding technology in the tea processing process has a vital impact on the quality of tea and the taste of the final product. With the continuous expansion of the tea market and the improvement of consumers' requirements for tea quality, tea grinding technology is also constantly developing and improving. In the traditional tea processing process, grinding is usually done by hand or simple mechanical devices. Although manual grinding can better preserve the aroma and flavor of tea, it is inefficient and cannot meet the needs of large-scale production. With the advancement of industrialization, various tea grinding equipment has emerged, such as a tea processing and grinding device in Publication No. CN221674445U. When in use, the tea to be ground is placed inside the conical barrel, and the tea enters between the upper grinding disc and the lower grinding disc through the conical barrel, and is ground by the rotation of the upper grinding disc. However, the shapes of different teas are different. For example, non-scattered tea leaves such as spherical and cake-shaped tea leaves cannot enter between the upper grinding disc and the lower grinding disc for grinding after being placed in the conical barrel. The tea leaves need to be crushed and then placed in the conical barrel for grinding. The scope of application is small and cannot adapt to the grinding of tea leaves of various shapes. In addition, during grinding, some tea powder will adhere to the side walls of the upper grinding disc and the lower grinding disc instead of falling into the storage tank, so that after the grinding is completed, it is necessary to manually scrape, collect and clean it, which increases the amount of manual labor.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. The present invention cooperates between the grinding roller and the grinding plate. After the tea leaves to be ground are manually poured into the interior of the shell, the motor 1 is started. The motor 1 drives the grinding roller to rotate, and the grinding roller drives the grinding plate to rotate. The grinding plate is resisted by the spring 1, so that the grinding plate presses the tea leaves toward the inner wall of the shell for grinding. During the grinding process of the grinding plate, the tea leaves can be quickly ground into powder through the extrusion of the grinding plate and the friction of the inner wall of the shell, thereby improving the tea grinding efficiency.

[0015] 2. The present invention cooperates between the grinding plate and the limit plate. During the grinding process, the motor 2 drives the support rod to squeeze the strong spring. The support rod causes the limit plate to move to the bottom of the movable groove through the interference between the second inclined surface and the first inclined surface, and locks the grinding plate by interfering with the side wall of the grinding plate. When the grinding roller is impacted by the strong spring, the grinding roller drives the grinding plate to impact the tea leaves, so that the tea leaves inside the shell are crushed, and the grinding continues to rotate and grind after the impact. The impact of the grinding plate on the tea leaves can effectively crush the block-shaped tea leaves, so that the tea leaves inside the shell can be ground, and there is no need to grind according to the shape of the tea leaves.

[0016] 3. The present invention cooperates between the grinding roller and the scraper. Before the grinding roller drives the grinding plate to hit the tea leaves, the grinding roller drives the push rod to hit the inner wall of the shell, so that the two scrapers move out of the movable bin 2 and are locked. When the grinding roller drives the grinding plate to hit the tea leaves, the scraper follows the grinding roller to hit the tea leaves, so that the side walls of the scraper squeeze and shear the tea leaves on the inner wall of the shell. When the grinding roller finishes hitting the tea leaves and continues to grind, the grinding roller drives the scraper to rotate, so that the tea powder between the two scrapers is discharged through the powder discharge groove. The scraper on one side of the rotation direction scrapes off the tea leaves and tea powder on the inner wall of the shell, and accumulates the tea leaves and tea powder on the side walls of the scraper so that the grinding roller will hit the tea leaves next time. The scraper scrapes the inside of the shell, so that the tea powder attached to the inner wall of the shell can be effectively collected and cleaned during and after the grinding process, without the need for manual cleaning again.

[0034] like Figure 3 and Figure 8-Figure 11 As shown, the side walls on both sides of the rotating sleeve 31 are respectively integrally formed with a sliding rod 2 314 and a movable key groove 315, and the sliding rod 2 314 and the movable key groove 315 are both slidably installed at the bottom of the movable warehouse 1 212, and the intermittent gear 3 33 is rotatably installed inside the movable warehouse 1 212, and the intermittent gear 3 333 is located inside the movable key groove 315, and the side wall of the movable key groove 315 is integrally formed with a tooth surface 316, and the intermittent gear 3 333 and the tooth surface 316 are meshed, and the bottom of the intermittent gear 333 is integrally formed with a gear 5 334, and the inside of the movable warehouse 1 212 is fixedly installed with a motor 2 323, and the output shaft of the motor 2 323 is fixedly connected with the intermittent gear 1 324, and the inside of the movable warehouse 1 212 is rotatably installed with a gear 4 332, and the gear 4 332 is meshed with the intermittent gear 1 324, and the top of the gear 4 332 is integrally formed with an intermittent gear 2 331, and the intermittent gear 2 331 is meshed with the gear 5 334.

[0035] Among them, the working principle of the rotating sleeve 31 is as follows: the rotation speed of the motor 1 321 and the motor 2 323 is the same, and they are started and shut down at the same time. When the motor 1 321 and the motor 2 323 are started, the motor 1 321 drives the grinding roller 21 to rotate and grind, the motor 2 323 drives the intermittent gear 1 324, the intermittent gear 1 324 and the gear 4 332 are meshed with each other, the gear 4 332 drives the intermittent gear 2 331 to rotate, the intermittent gear 2 331 and the gear 5 334 rotate, the gear 5 334 drives the intermittent gear 3 333 to rotate, the intermittent gear 3 333 and the tooth surface 316 are meshed, so that the grinding roller 21 rotates inside the shell 1 and moves laterally at the same time, and the grinding is cancelled during the movement of the grinding roller 21.

[0036] Further references Fig. 9 and Fig.11 To explain, the intermittent gear 1 324 meshes with the gear 4 332 once for every rotation of the intermittent gear 1 324, the gear 4 332 rotates one circle for every four rotations of the intermittent gear 1 324, the intermittent gear 2 331 meshes with the gear 5 334 once for every rotation of the gear 4 332, and the intermittent gear 1 324, the intermittent gear 2 331 and the gear 5 334 have the same number of teeth, so that the intermittent gear 3 333 rotates once for every four rotations of the intermittent gear 1 324.

[0037] like Figure 4 , Figure 5 , Fig. 9 and Fig.10 As shown, a movable groove 216 is provided at the bottom of the movable bin 1 212, and the movable bin 1 212 and the movable bin 215 are interconnected through the movable groove 216. The bottoms of the slide rod 2 314 and the movable key groove 315 are integrally formed with a support rod 311, and the support rod 311 is movably installed inside the movable groove 216. A strong spring 312 is provided between the side wall of the support rod 311 and the side wall of the movable groove 216.

[0038] Among them, the working principle of the strong spring 312 is: when the grinding roller 21 moves laterally and the grinding is cancelled, the support rod 311 squeezes the strong spring 312, causing the strong spring 312 to contract. When the intermittent gear three 333 disengages from the tooth surface 316, the strong spring 312 releases the elastic force, causing the grinding roller 21 to quickly hit the tea leaves inside the shell 1.

[0039] like Figure 2 and Figure 6As shown, the side wall of the push rod 23 is integrally formed with two scrapers 232, the grinding plate 22 is located between the two scrapers 232, a spring 1 221 is provided between the grinding plate 22 and the side wall of the movable bin 215, a spring 231 is provided between the scraper 232 and the side wall of the movable bin 215, and a side wall of one of the scrapers 232 is provided with a plurality of evenly distributed powder discharge grooves 234, and the powder discharge grooves 234 are located at the bottom of the scraper 232.

[0040] like Figure 3-Figure 7 As shown, a locking plate 24 is slidably installed on the top of the movable bin 215, and a locking tooth 241 is integrally formed on the bottom of the locking plate 24. Locking grooves 233 are provided on the tops of the two scrapers 232, and the locking teeth 241 and the locking grooves 233 are meshed with each other. A convex tooth 222 is integrally formed on the top of the grinding plate 22, and the convex tooth 222 and the locking tooth 241 are meshed with each other. A spring 3 242 is provided between the locking plate 24 and the top of the movable bin 215.

[0041] Among them, the working principle of the locking plate 24 is: when the grinding roller 21 moves laterally, the grinding roller 21 drives the push rod 23 to move, so that the push rod 23 hits the inner wall of the shell 1, the scraper 232 moves out of the movable bin 215, and the locking plate 24 drives the locking tooth 241 to hit the locking groove 233, and the scraper 232 is locked.

[0042] Further references Figure 6 To explain, the working principle of the scraper 232 is: when the scraper 232 is locked, when the grinding roller 21 hits the inner wall of the shell 1, the grinding roller 21 drives the scraper 232 to hit the inner wall of the shell 1, and the scraper 232 hits the tea leaves on the inner wall of the shell 1 and squeezes them. When the impact of the grinding roller 21 ends and the grinding is resumed, the grinding roller 21 drives the scraper 232 to rotate, and the tea powder between the two scrapers 232 is discharged through the powder discharge groove 234. The scraper 232 on one side of the rotation direction scrapes off the tea leaves and tea powder on the inner wall of the shell 1 while following the rotation of the grinding roller 21, and makes the tea leaves and tea powder accumulate on the side wall of the scraper 232 so that the grinding roller 21 can hit it next time.

[0043] like Figure 4 , Figure 5 and Figure 7 As shown, a limit plate 25 is slidably installed on the top of the movable bin 215, and a side wall of the limit plate 25 is provided with an inclined surface 251, and the inclined surface 251 is located inside the movable groove 216. A slope 2 313 is provided at the bottom of the support rod 311, and a spring 4 252 is provided between the limit plate 25 and the top of the movable bin 215. A slide bar 253 is integrally formed at the bottom of the limit plate 25, and the slide bar 253 is slidably inserted into the bottom of the movable groove 216.

[0044] Among them, the working principle of the limit plate 25 is: in the process of the support rod 311 squeezing the strong spring 312, the second inclined surface 313 hits the first inclined surface 251, so that the limit plate 25 moves to the bottom of the movable groove 216, and the limit plate 25 hits the side wall of the grinding plate 22. When the grinding roller 21 collides, the grinding roller 21 drives the grinding plate 22 to collide with the tea leaves through the limit plate 25. When the impact of the grinding roller 21 is completed, the support rod 311 returns to its position, the second inclined surface 313 moves away from the first inclined surface 251, and the limit plate 25 shrinks and returns to its position.

[0045] Further references Figure 3 The working principle of the grinding plate 22 is explained as follows: during the grinding process of the grinding roller 21, the grinding roller 21 drives the grinding plate 22 to rotate, and the grinding plate 22 is ground by the interference of the spring 1 221. When the impact of the grinding roller 21 is completed, the grinding plate 22 is in contact with the tea leaves accumulated on the inner wall of the shell 1 and contracts, so that in the process of the grinding plate 22 following the grinding roller 21 to rotate and grind, the grinding plate 22 grinds the tea leaves between the two scrapers 232. When the grinding of the tea leaves between the two scrapers 232 is completed, the grinding plate 22 returns to its original position, and the convex tooth 1 222 moves with the grinding plate 22, so that the convex tooth 1 222 is in contact with the locking tooth 241, the locking plate 24 contracts, the scraper 232 is unlocked, and returns to its original position by the spring 231.

[0046] like Figure 1 and Fig.12 As shown, a discharge port 124 is provided at the bottom of the housing 1, a discharge plate 121 is slidably installed inside the discharge port 124, a screw hole 123 and a rotating hole 125 are integrally formed above the discharge plate 121 and the discharge port 124, a screw rod 122 is rotatably installed inside the rotating hole 125, a discharge valve 12 is fixedly installed on the side wall of the screw rod 122, the screw hole 123 is located between the rotating hole 125 and the discharge valve 12, the screw rod 122 is rotatably installed in the screw hole 123, and threadedly engaged.

[0047] Among them, the working principle of the discharge valve 12 is: when the tea leaves are ground, the discharge valve 12 is manually rotated to rotate the screw 122, and the discharge plate 121 is moved out of the shell 1 and the discharge port 124 is opened to discharge the powder through the threaded cooperation between the screw hole 123 and the screw 122.

[0048] The specific working principle and use method of the present invention are explained in detail below: manually open the upper cover 13, pour the tea leaves to be ground into the interior of the shell 1, start the motor 1 321 and the motor 2 323, the motor 1 321 drives the grinding roller 21 to rotate around the fixed shaft 141 through the driving gear 322, and the motor 2 323 drives the intermittent gear 3 333 to rotate, when the intermittent gear 3 333 rotates and meshes with the tooth surface 316, the grinding roller 21 rotates and moves laterally, so that the support rod 311 squeezes the strong spring 312, and when the intermittent gear 3 333 and the tooth surface 316 are no longer meshed, the strong spring 312 contacts the support rod 311, so that the grinding roller 2 1 impacts the tea leaves accumulated during the grinding process. When the grinding roller 21 moves horizontally, the grinding roller 21 drives the push rod 23 to move, and the push rod 23 hits the inner wall of the shell 1, so that the two scrapers 232 move out of the movable bin 215 and are locked. At the same time, in the process of the support rod 311 squeezing the strong spring 312, the limit plate 25 hits the side wall of the grinding plate 22, so that the grinding plate 22 is locked. When the grinding roller 21 impacts, the grinding roller 21 drives the two scrapers 232 and the grinding plate 22 to impact the tea leaves. When the grinding roller 21 completes the impact and continues to rotate and grind, the grinding roller 21 drives the grinding plate 22 to rotate, and the grinding plate 22 grinds the tea leaves between the two scrapers 232 through the resistance of the spring 1 221.

[0049] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
