An inlet port is connected to the bottom of the inlet cover, and an outlet port is provided below the inlet port. An outlet pipe is connected to the outside of the outlet port, and an outlet valve is provided above the outlet pipe. The weighing box is installed below the storage box, and an mounting plate is fixed to the surface of the weighing box. A guide pipe is provided inside the mounting plate, and a storage groove is provided below the guide pipe. Air pressure rods are connected to both sides of the storage groove, and an air pressure valve is provided below the air pressure rods. A weighing plate is provided in the middle of the air pressure valve, and a slide rail is provided on the upper surface of the weighing plate. This weighing device for tea production can automatically weigh tea leaves, saving a lot of time, making the measurement results more accurate, and improving the efficiency of weighing.

[0004] Although the aforementioned patent can automatically weigh tea leaves, when the tea leaves are put into the discharge box after weighing, the tea leaves that are still falling from above will also enter the discharge box, making the actual weight of the tea leaves greater than the weighed weight. This would cause losses for merchants if the tea leaves are sold at the price based on the weighed weight. Therefore, we propose a weighing device for tea preparation to solve the above technical problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a weighing device for tea preparation that can overcome or at least partially solve the above problems.

[0009] Preferably, a storage plate is provided between the storage cavity and the transfer cavity, and a conveyor belt is fixedly installed inside the transfer cavity, with one end of the conveyor belt passing through the transfer cavity and located in the discharge cavity.

[0010] Preferably, a transfer switch is provided on the inner wall of the material discharge cavity near the conveyor belt, and the transfer switch is located at the position where the first baffle contacts the inner wall of the material discharge cavity.

[0011] Preferably, one end of the second telescopic rod is rotatably connected to one side of the second pneumatic rod, and the end of the second telescopic rod away from the second pneumatic rod is rotatably connected to the second baffle. The second telescopic rod is rotatably connected to the inner wall of the placement cavity, and the second baffle passes through the material drop plate and communicates with the material drop cavity.

[0012] Preferably, the bottom of the storage plate has a through hole that communicates with the transfer cavity, and a movable plate is installed at the through hole position of the storage plate.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Example 1:

[0026] Reference Figures 1-6 A weighing device for tea preparation includes a weighing box 1 with a storage cavity 101, a transfer cavity 102, a discharge cavity 103, and a placement cavity 104. The transfer cavity 102 is connected to the storage cavity 101 and the discharge cavity 103. A discharge plate 106 is provided between the placement cavity 104 and the discharge cavity 103. A left placement plate 301 and a right placement plate 302 are provided at the bottom of the discharge cavity 103. A blocking mechanism is fixedly connected to one side of the left placement plate 301. The blocking mechanism is located in the placement cavity 104. The bottom of the left placement plate 301 and the right placement plate 302 are in contact with a weighing plate 3. A discharge box 109 is installed at the bottom of the weighing plate 3. The discharge box 109 is fixedly installed at the bottom of the placement cavity 104.

[0027] When this device is in use, tea leaves enter the transfer cavity 102 through the storage cavity 101, and then fall into the discharge cavity 103 onto the left and right placement plates 301 and 302. The weighing plate 3 weighs the tea leaves. When the tea leaves on the left and right placement plates 301 and 302 reach the specified weight, the left and right placement plates 301 and 302 open, and the tea leaves fall into the discharge box 109. At the same time, the blocking mechanism blocks the tea leaves that have not yet fallen onto the left and right placement plates 301 and 302, preventing the unweighed tea leaves from falling into the discharge box 109 when the left and right placement plates 301 and 302 are opened.

[0028] Therefore, when the weighed tea leaves fall into the discharge box 109 through the left and right placement plates 301 and 302, the blocking mechanism blocks the tea leaves that have not yet fallen onto the left and right placement plates 301 and 302, preventing unweighed tea leaves from falling into the discharge box 109.

[0029] Example 2:

[0030] Reference Figures 1-6 A weighing device for tea preparation is basically the same as in Example 1, but further: a first air pressure rod 401 and a second air pressure rod 501 are fixedly connected to one side of the left placement plate 301 and the right placement plate 302 respectively; a first air pressure valve 4 and a second air pressure valve 5 are fixedly installed at the bottom of the placement cavity 104; the first air pressure valve 4 and the second air pressure valve 5 are telescopically connected to the first air pressure rod 401 and the second air pressure rod 501 respectively.

[0031] When it is necessary to move the left shelf 301 and the right shelf 302, the first air pressure valve 4 and the second air pressure valve 5 drive the first air pressure rod 401 and the second air pressure rod 501, so that the left shelf 301 and the right shelf 302 begin to move away from or towards each other.

[0032] Example 3:

[0033] Reference Figures 1-6 A weighing device for tea preparation is basically the same as in Example 2, but further: the shielding mechanism includes a first telescopic rod 402 and a first baffle 403. The two ends of the first telescopic rod 402 are rotatably connected to the first pneumatic rod 401 and the first baffle 403 respectively. The first telescopic rod 402 is rotatably connected to the inner wall of the placement cavity 104. The first baffle 403 passes through the material dropping plate 106 and communicates with the material dropping cavity 103.

[0034] When the tea leaves on the left and right storage plates 301 and 302 reach the designated weight, they begin to separate and fall into the discharge box 109 under the drive of the first pneumatic rod 401 and the second pneumatic rod 501. At this time, the first telescopic rod 402 connected to the first pneumatic rod 401 begins to move the first baffle 403 into the discharge cavity 103 to block the tea leaves that are still falling from above, preventing them from falling into the discharge box 109. When the left and right storage plates 301 and 302 begin to approach and close together, the first baffle 403 begins to move away from the discharge cavity 103 and into the placement cavity 104.

[0035] Example 4:

[0036] Reference Figures 1-6 A weighing device for tea preparation is basically the same as in Example 1, but further: a storage plate 107 is provided between the storage cavity 101 and the transfer cavity 102, and a conveyor belt 2 is fixedly installed in the transfer cavity 102, with one end of the conveyor belt 2 passing through the transfer cavity 102 and located in the discharge cavity 103.

[0037] The tea leaves that enter the transfer cavity 102 are conveyed to the discharge cavity 103 by the conveyor belt 2.

[0038] Example 5:

[0039] Reference Figures 1-6 A weighing device for tea preparation is basically the same as that in Example 4, but further: a transfer switch 201 is provided on the inner wall of the material discharge cavity 103 near the conveyor belt 2. The transfer switch 201 is located at the position where the first baffle 403 contacts the inner wall of the material discharge cavity 103 in the material discharge cavity 103.

[0040] When the first baffle 403 enters the discharge cavity 103 and begins to block the tea leaves above, the first baffle 403 begins to contact the transfer switch 201, causing the conveyor belt 2 to stop conveying the tea leaves. When the first baffle 403 begins to return to the placement cavity 104 and releases contact with the transfer switch 201, the conveyor belt 2 begins to convey the tea leaves into the discharge cavity 103.

[0041] Example 6:

[0042] Reference Figures 1-6 A weighing device for tea preparation is basically the same as in Example 2, but further: one end of the second telescopic rod 502 is rotatably connected to one side of the second pneumatic rod 501, and the end of the second telescopic rod 502 away from the second pneumatic rod 501 is rotatably connected to the second baffle 503. The second telescopic rod 502 is rotatably connected to the inner wall of the placement cavity 104, and the second baffle 503 passes through the material dropping plate 106 and communicates with the material dropping cavity 103.

[0043] When the left and right storage plates 301 and 302 begin to move away from each other, the second telescopic rod 502 connected to the second pneumatic rod 501 begins to move the second baffle 503 into the discharge cavity 103, blocking the tea leaves that are not blocked by the first baffle 403. When the left and right storage plates 301 and 302 begin to move closer together, the second baffle 503 moves away from the discharge cavity 103 at a slower rate than the first baffle 403, so that before the left and right storage plates 301 and 302 are fully closed, the tea leaves above the first baffle 403 are blocked by the second baffle 503, preventing the tea leaves from falling into the discharge box 109 without being weighed.

[0044] Example 7:

[0045] Reference Figures 1-6 A weighing device for tea preparation is basically the same as in Example 4, but further: the bottom of the storage plate 107 is provided with a through hole that is connected to the transfer cavity 102, a movable plate 105 is installed at the through hole position of the storage plate 107, and a movable rod 108 that passes through the storage plate 107 and the outer wall of the weighing box 1 is fixedly connected to one side of the movable plate 105.

[0046] The amount of tea leaves entering the transfer cavity 102 from the storage cavity 101 can be controlled by adjusting the movable rod 108.

[0047] Example 8:

[0048] Reference Figures 1-6 A weighing device for tea preparation is basically the same as that in Example 1, but further: a feeding hopper 110 is fixedly installed on the top of the weighing box 1, and the feeding hopper 110 is connected to the storage cavity 101.

[0049] The feed hopper 110 can increase the feeding area of ​​the storage cavity 101, allowing more tea leaves to enter the storage cavity 101.

[0050] When the weighed tea leaves fall into the discharge box 109 via the left and right placement plates 301 and 302, the blocking mechanism blocks the tea leaves that have not yet fallen onto the left and right placement plates 301 and 302, thus preventing unweighed tea leaves from falling into the discharge box 109.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
