Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a stem-leaf separation device for matcha production. Background Art

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. It is also known as tea, tea, tea leaves, and tea. The ingredients of tea include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are good for health. Tea beverages made from tea are one of the three major beverages in the world. Tea leaves can be processed into matcha. In the production process of matcha, the separation of tea stems and tea leaves is one of the key steps.

[0003] Chinese patent CN215029402U discloses a device for separating stems and leaves for matcha production. The device has a reasonable structural design and is easy to use. It can effectively separate tea leaves from tea stems to facilitate subsequent matcha processing and use, which not only improves the taste of matcha products, but also improves the quality of matcha, and has strong social practicality.

[0004] However, during the process of separating the stems and leaves by the above-mentioned device, only the tea stems can be discharged and stacked from the machine, and both the tea leaves and the tea stems cannot be discharged and separated and stacked. When the machine is full of separated tea leaves, the staff is required to manually move the separated tea leaves out of the machine, which results in the staff being required to move the tea leaves out of the machine again after a specific amount of stems and leaves are separated, increasing the staff's workload. At the same time, screening the tea leaves and leaf stems through a fixed screening net will cause the tea leaves and leaf stems to block the mesh of the screening net, making it impossible to separate the tea leaves and leaf stems.

[0005] Based on this, a stem-leaf separation device for matcha production is now provided, which can eliminate the disadvantages of existing devices. Utility Model Content

The small rotating rod 202 and the large rotating rod 204 are arranged in parallel up and down, and one end rotates through the side wall of the separation box 100, and the other end is rotatably connected to the inner wall of the separation box 100. The small rotating rod 202 and the large rotating rod 204 are both provided with a separation hook 206. The separation box 100 is provided with a vibration mechanism 300 for driving the screen plate 102 to reciprocate left and right in the separation box 100. The separation box 100 is located below the separation mechanism 200 and is provided with a breaking up mechanism 400 for stirring the separated stem leaves to break up the stem leaves that are gathered together.

[0046] During operation, tea leaves enter the separation box 100 through the feed port 101, driving the small rotating roller 202 and the large rotating roller 204 to rotate. Under the rotation and stirring action of the small rotating roller 202 and the large rotating roller 204, the second transmission belt 205 on the small rotating roller 202 and the large rotating roller 204 separates the tea leaves and the leaf stems. The separated tea leaves and leaf stems are broken up by the separation mechanism 200 and fall onto the screening plate 102. The vibration mechanism 300 is started to make the screening plate 102 reciprocate back and forth in the separation box 102, so that the tea leaves and leaf stems can be evenly laid on the screening plate 102. The breaking mechanism 400 further promotes the breaking up of the stems and leaves. After being screened by the screening plate 102, the leaf stems fall into the collecting plate 103 for collection, and the tea leaves remain on the screening plate 102 and slide down for collection.

The first driving disk 302 is symmetrically provided with two groups of side walls along the central axis of the separation box 100 and rotates through the separation box 100 and the collecting plate 103. The first connecting rod 303 is fixed on the first driving disk 302 and is located at the edge of its circumference. One end of the driving rod 304 is rotatably sleeved on the first connecting rod 303, and the other end of the driving rod 304 is rotatably connected to the side wall of the screening plate 102. The slider 305 is symmetrically arranged on the side wall of the screening plate 102. The separation box 100 is provided with a slide groove 306 for the slider 305 to slide. The slide groove 306 is arranged parallel to the screening plate 102. The side wall of the separation box 100 is provided with a moving and breaking up component 500 for further breaking up the stems in the screening plate 102.

[0048] The tea leaves and leaf stems separated by the separation mechanism 200 are broken up and fall onto the screening plate 102, and the second motor 301 is started to drive the first driving disk 302 to rotate, so that the first connecting rod 303 on the first driving disk 302 drives the driving rod 304 to rotate around the first connecting rod 303, and then the driving rod 304 drives the screening plate 102 to reciprocate left and right in the slide groove 306 on the separation box.

[0049] See also Figure 7-Figure 8As shown, the toggle breaking assembly 500 includes a second driving disk 502, a second connecting rod 503, a sliding rod 504, an annular sleeve 505, a sliding sleeve 506, a mounting rod 507 and a toggle rod 508. The second driving disk 502 is symmetrically provided with two groups along the central axis of the separation box 100 and is rotatably arranged on the inner side wall of the separation box 100. The second driving disk 502 is connected to the output end of the second motor 301 through a third transmission belt 501. The second connecting rod 503 is fixedly arranged on the second driving disk 502 and is located at the edge of its circumference. The sliding sleeve 506 is arranged along the separation box 100. 00 is symmetrically provided with two groups on the central axis and fixed on the inner wall of the screen plate 102, the sliding rod 504 is provided with two sliding sleeves 506 and are located above the screen plate 102 and parallel to the screen plate 102, the annular sleeve 505 is fixed on one end of the sliding rod 504 and close to the side of the second driving disk 502, the annular sleeve 505 is slidably sleeved on the second connecting rod 503, the mounting rod 507 is provided with multiple and fixed between the two sliding rods 504, and multiple toggle rods 508 are fixed on the side of the mounting rod 507 close to the screen plate 102.

[0050] When the tea leaves are screened on the screening plate 102, the second driving disk 502 is driven to rotate by the second motor 301, and the second connecting rod 503 on the second driving disk 502 moves back and forth in the annular sleeve 505, so that the annular sleeve 505 drives the sliding rod 504 to slide in the sliding sleeve 506, thereby driving the mounting rod 507 and the toggle rod 508 to further break up the stems of the tea leaves in the screening plate 102, so as to facilitate the screening of the tea leaves and the leaf stems.

[0051] See also Figure 3-Figure 5 As shown, there are three small rotating rollers 202 and two large rotating rollers 204 . The two large rotating rollers 204 are arranged laterally at intervals, and the small rotating rollers 202 are arranged above the three gaps formed by the two large rotating rollers 204 and the side walls of the separation box 100 .

[0052] The arrangement of the small rotating roller 202 and the large rotating roller 204 allows the tea leaves to be stirred more evenly in the separation box 100. The three small rotating rollers 202 are located above the three gaps between the two large rotating rollers 204, so that the tea leaves are stirred in multiple directions, thereby improving the separation effect of the separation hook 206 on the leaf stems.

[0053] See also Figure 3-Figure 5As shown, the separation mechanism 200 also includes a first motor 201, a driving gear 207 and a driven gear 208. The driving gear 207 is fixed on one of the small rotating rods 202. Each small rotating rod 202 is connected to each other through a first transmission belt 203. The driven gear 208 is fixed on one of the large rotating rods 204. The driving gear 207 and the driven gear 208 are meshed. The two large rotating rods 204 are connected to each other through a second transmission belt 205. The first motor 201 is fixed on the separation box 100, and the output end of the first motor 201 is connected to one end of the small rotating rod 202 that passes through the side wall of the separation box 100.

[0054] The tea leaves enter the separation box 100 through the feed port 101, and the first motor 201 is started to drive one of the small rotating rods 202 to rotate, and the other small rotating rods 202 are driven to rotate through the two first transmission belts 203 respectively. When the small rotating rod 202 rotates, the driving gear 207 is driven to rotate. Since the driving gear 207 is meshed with the driven gear 208, the driven gear 208 drives one of the large rotating rods 204 to rotate, and the other large rotating rod 204 is driven to rotate through the second transmission belt 205. The small rotating rod 202 and the large rotating rod 204 rotate synchronously, so that the separation hooks 206 on the small rotating rod 202 and the large rotating rod 204 separate the leaf stems.

[0055] See also Figure 3 As shown, the breaking up mechanism 400 includes a third motor 401, a rotating shaft 402 and a breaking up rod 403, one end of the rotating shaft 402 rotates and passes through the side wall of the separation box 100, and the other end of the rotating shaft 402 is rotatably connected to the inner wall of the rotating shaft 402, and the breaking up rod 403 is provided with multiple and fixed sleeves on the rotating shaft 402, the third motor 401 is fixedly provided on the side wall of the separation box 100, and the output end of the third motor 401 is transmission-connected to one end of the rotating shaft 402 that passes through the side wall of the separation box 100.

[0056] The third motor 401 drives the rotating shaft 402 to rotate, thereby driving the breaking rod 403 fixed on the rotating shaft to break up the stems and leaves gathered together.

[0057] See also Figure 3 As shown, a material guide plate 105 is fixedly provided on the inner wall of the separation box 100 , and the material guide plate 105 is arranged obliquely and is located above the screening plate 102 .

[0058] The obliquely cut guide plate 105 is located above the screening plate 102, so as to facilitate the separated and broken leaf stems to enter the screening plate 102 for screening.

[0059] See also Figure 3 As shown, a light 104 is fixedly provided in the separation box 100 , and the light 104 is located above the small rotating roller 202 .

[0060] The arrangement of the lighting 104 allows the tea leaves entering the separation box 100 to be roughly dried, causing the water content of the tea leaves to be lost, thereby reducing the toughness and facilitating the separation of the leaf stems.

[0061] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
