DETAILED DESCRIPTION
[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.
[0019] A weighing device for tea production, such as Figure 1-Figure 5 As shown, it includes a support base 1, a weighing device 2, a storage box 3, a movable baffle 4, a rack 5, a gear 6, a first motor 7, a first threaded rod 8, a weighing box 9 and a feeding frame 18. The weighing device 2 is installed on the top of the support base 1. The top of the support base 1 is fixedly connected with a storage box 3 for storing tea leaves. The storage box 3 is located directly above the weighing device 2. The bottom of the storage box 3 is slidably connected with two movable baffles 4. The movable baffles 4 are symmetrically arranged. When the two movable baffles 4 are close to each other, they can prevent the tea leaves from falling out. The front and rear sides of the two movable baffles 4 are fixedly connected with racks 5. The front and rear sides of the box 3 are rotatably connected with gears 6, and the corresponding two racks 5 are meshed with the gears 6. The front side of the storage box 3 is rotatably connected with a first threaded rod 8, and a first motor 7 is installed on the front side of the storage box 3. The output shaft of the first motor 7 is fixedly connected to the first threaded rod 8, and the first threaded rod 8 is fixedly connected to the rack 5 of the right movable baffle 4. A weighing box 9 is placed on the top of the weighing device 2, and a feeding frame 18 is fixedly connected to the right side of the support base 1. When using the weighing device, there is no need to manually pour the tea into the weighing box 9 for weighing, which greatly improves the processing efficiency, accuracy and hygiene standards of the tea.
[0020] When the tea leaves need to be weighed, the first threaded rod 8 is driven to rotate by the first motor 7, thereby driving the right movable baffle 4 to move to the right, and the right rack 5 moves to the right and drives the left rack 5 to move to the left through the gear 6, so that the left and right movable baffles 4 can slide away from each other, and the tea leaves fall from the storage box 3 into the weighing box 9, and the tea leaves in the weighing box 9 are weighed by the weighing device 2. After the tea leaves in the weighing box 9 reach the required weight, the left and right movable baffles 4 are reset by the first motor 7 to complete the weighing of the tea leaves.
[0021] like Figure 2and Figure 3 As shown, a shielding cloth 41 is also included. The bottom of the left and right movable baffles 4 are fixedly connected with the shielding cloth 41. The shielding cloth 41 is made of transparent material, which is convenient for observing the pouring of tea leaves. The shielding cloth 41 can prevent the tea leaves from splashing or overflowing when the tea leaves are poured quickly or in large quantities, thereby avoiding waste.
[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a moving mechanism, a first wedge block 17 and a discharge assembly. The top of the support base 1 is connected to a moving mechanism for moving the weighing box 9. The front and rear sides of the discharge frame 18 are fixedly connected to the first wedge block 17, and the inclined surface of the first wedge block 17 faces downward. The bottom of the weighing box 9 is connected to the discharge assembly. Through the cooperation between the discharge assembly and the first wedge block 17, the tea leaves in the weighing box 9 can be poured into the discharge frame 18 to complete the unloading process of the tea leaves. The moving mechanism includes a second motor 13, a second threaded rod 14, a guide rod 15 and a cylinder 16. The front of the top of the support base 1 is connected to the first wedge block 17. A second motor 13 is installed on the side, and a second threaded rod 14 is fixedly connected to the output shaft of the second motor 13. The second threaded rod 14 is rotatably connected to the support base 1, and a guide rod 15 is fixedly connected to the top rear side of the support base 1. The second threaded rod 14 and the guide rod 15 are close to each other and are connected with a cylinder 16. The front cylinder 16 is threadedly connected to the second threaded rod 14, and the rear cylinder 16 is slidably connected to the guide rod 15. The piston rods of the front and rear cylinders 16 are in contact with the weighing box 9, and there is no need to manually pour the tea in the weighing box 9 into the unloading frame 18, thereby further improving the processing efficiency of the tea.
[0023] After the weighing of the tea leaves is completed, the weighing box 9 is clamped by extending the piston rod of the cylinder 16, and then the second motor 13 drives the second threaded rod 14 to rotate, so that the weighing box 9 moves to the right along the guide rod 15 for unloading operation, and then the second motor 13 resets the weighing box 9 for the next weighing.
[0024] like Figure 4As shown, the unloading assembly includes a rotating plate 10, a wedge plate 11 and an elastic member 12. The top and bottom of the weighing box 9 are both open. The bottom of the weighing box 9 is rotatably connected to the rotating plate 10. The rotating connection between the rotating plate 10 and the weighing box 9 is fixedly connected to two elastic members 12. The elastic member 12 is configured as a torsion spring. The front and rear sides of the rotating plate 10 are fixedly connected to the wedge plate 11, and the inclined surface of the wedge plate 11 faces upward. When the unloading assembly cooperates with the first wedge block 17, the weighing box 9 moves to the right so that the inclined surface of the wedge plate 11 contacts the inclined surface of the first wedge block 17, so that the first wedge block 17 squeezes the wedge plate 11, thereby causing the rotating plate 10 to rotate downward, the elastic member 12 is compressed, and the tea leaves fall from the weighing box 9 into the unloading frame 18. When the weighing box 9 moves to the left to reset, the wedge plate 11 moves to the left away from the first wedge block 17, and the elastic member 12 returns to its original state to reset the rotating plate 10, which can facilitate the unloading of the tea leaves and can be reset after unloading to weigh the next batch of tea leaves.
[0025] like Figure 1 and Figure 2 As shown, the top of the material box 18 is higher than the top of the support base 1, and the top of the material box 18 is lower than the wedge plate 11. When the weighing box 9 is unloaded, it can prevent the tea leaves from falling on the top of the support base 1, avoid wasting tea leaves, and ensure the accuracy of tea leaves weighing.
[0026] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes a second wedge block 19, and the piston rods of the front and rear cylinders 16 are fixedly connected to the second wedge block 19, and the inclined surfaces of the second wedge block 19 are facing upward. The front and rear sides of the weighing box 9 are provided with wedge grooves 91 adapted to the wedge blocks, so that the weighing box 9 is lifted up, which can prevent the weighing box 9 from being damaged by friction with the weighing device 2 when it moves to the right. When the piston rods of the front and rear cylinders 16 are extended, the front and rear second wedge blocks 19 approach each other, and at the same time, the front and rear second wedge blocks 19 slide in the wedge grooves 91, so that the weighing box 9 moves upward away from the weighing device 2. When the weighing box 9 is reset, the piston rods of the front and rear cylinders 16 are retracted to make the front and rear second wedge blocks 19 move away from each other, so that the weighing box 9 contacts the weighing device 2 and resets.
[0027] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
