Abstract
Description
Technical Field
[0001] This invention relates to the field of tea color sorting technology, and in particular to a color sorter for Liubao tea production. Background Technology
[0002] Liubao tea belongs to the category of dark tea. It is made from the fresh leaves of tea trees of the Cangwu County group variety, Guangxi large and medium leaf variety and their separated and selected varieties and strains. It is processed according to specific techniques and has unique quality characteristics. The production process of Liubao tea includes steps such as shaking and sieving, sorting and tightening.
[0003] When tea leaves are processed by pressing the gate, the leaves may be damaged, resulting in a large number of broken leaves. Currently, color sorters are commonly used to replace the gate for grading tea leaves. However, when existing color sorters blow out substandard tea leaves, they may accidentally blow away high-quality tea leaves, affecting the sorting effect. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a color sorter for Liubao tea production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A color sorter for Liubao tea production includes a base, a mounting seat mounted on the top of the base via a frame, and a storage housing mounted on the mounting seat via springs. An inclined color sorting chute is mounted on the top of the base. A color sorting mechanism is mounted on the inclined surface of the color sorting chute away from the base for color sorting tea leaves falling into the chute. The color sorting mechanism includes a mounting housing mounted on the side of the color sorting chute, with a camera and lighting components installed inside the mounting housing, and nozzles mounted on the inner wall of the color sorting chute. It also includes an air pump for blowing air into the nozzles. A collection housing is mounted on the inclined surface of the color sorting chute near the base, with the collection housing located at an opening within the color sorting chute and the mounting housing located at an opening within the color sorting chute. The positions of the nozzles correspond to each other; the bottom inner wall of the collection shell is inclined, and a defective product discharge pipe is installed at the bottom of the collection shell for discharging defective tea leaves sprayed into the collection shell through the nozzle; a sieve plate is installed at the opening of the defective product discharge pipe inside the collection shell for sieving the defective tea leaves sprayed into the collection shell; a guide plate is installed on the inner wall of the color sorting chute for guiding the tea leaves that slide down the color sorting chute; a buffer mechanism is provided inside the collection shell for decelerating and buffering the defective tea leaves sprayed into the collection shell through the nozzle; a movable mechanism is provided inside the collection shell for moving the tea leaves that fall onto the sieve plate when the nozzle blows the defective tea leaves into the collection shell.
[0007] Preferably, a movable door is movably installed at the end of the collection housing away from the color sorting slide.
[0008] Preferably, the buffer mechanism includes an air outlet housing installed on the inner wall of the collection housing. The position of the air outlet housing corresponds to the position of the airflow ejected from the nozzle. An air outlet hole is provided on the side of the air outlet housing near the nozzle. The interior of the air outlet housing is connected to the air outlet end of the air pump through an air inlet pipe.
[0009] Preferably, the side of the air outlet housing near the nozzle is curved to guide the tea leaves blown to the side of the air outlet housing to the top of the screening plate.
[0010] Preferably, the movable mechanism includes a fixed housing installed on the inner wall of the top of the collecting housing. A vertically arranged rotating shaft is movably installed on the side of the fixed housing near the screening plate. A movable side wing is installed on the side of the rotating shaft. The position of the movable side wing corresponds to the position of the airflow ejected from the nozzle, which is used to increase the contact area between the rotating shaft and the airflow ejected from the nozzle, and to drive the rotating shaft to rotate when the nozzle ejects gas. A rotating seat is installed at the end of the rotating shaft near the screening plate. A through hole is opened on the rotating seat, and a vertically arranged material feeding component is movably arranged inside the through hole.
[0011] Preferably, the end of the rotating shaft located inside the fixed housing is equipped with a mounting wing, and the side of the mounting wing is connected to the inner wall of the fixed housing through a return spring, which is used to pull the rotated rotating shaft to return to its original position when the nozzle stops spraying air.
[0012] Preferably, the rotating shaft is located between the air outlet housing and the nozzle, and the bottom of the material feeding component is in contact with the top of the screening plate; when the nozzle stops spraying air, the side of the movable wing is perpendicular to the direction of the airflow ejected from the nozzle.
[0013] Preferably, the feeding component is made of a flexible material.
[0014] Preferably, a feeding trough is installed at the bottom of the storage shell to transfer the tea leaves fed from the storage shell to the top opening of the color sorting chute; a vibration component is installed on the side of the storage shell to drive the storage shell and the feeding trough to shake.
[0015] Preferably, the end of the color sorting chute away from the storage shell is provided with a premium product discharge pipe.
[0016] The beneficial effects of this invention are as follows:
[0017] During operation, tea leaves are fed from the storage shell into the color sorting chute. As the tea leaves slide down the chute, the lighting unit illuminates them, and the camera captures images. When the camera detects defective tea leaves, the nozzle sprays air onto them, blowing them into the collection shell. At this point, the buffer mechanism slows down and cushions the defective tea leaves, preventing them from colliding with the inner wall of the collection shell and breaking. The cushioned and slowed tea leaves fall onto the screening plate, and after being screened, they fall into the defective tea discharge pipe for further processing. Larger tea leaves screened by the screening plate slide down the bottom inner wall of the collection shell to one end of the collection shell. This process separates good tea leaves that are accidentally sprayed into the collection shell during color sorting, improving the sorting effect. Furthermore, when the nozzle sprays air, the moving mechanism moves under the action of the airflow and agitates the tea leaves that have fallen onto the screening plate, improving the screening efficiency of the screening plate.

Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0024] Reference Figures 1 to 4 A color sorter for Liubao tea production includes a base 17, a mounting base 3 mounted on the top of the base 17 via a frame 1, a storage housing 4 mounted on the mounting base 3 via a spring, an inclined color sorting slide 10 mounted on the top of the base 17, a color sorting mechanism 7 mounted on the inclined surface of the color sorting slide 10 away from the base 17, for color sorting tea leaves falling into the color sorting slide 10; the color sorting mechanism 7 includes a mounting housing 72 mounted on the side of the color sorting slide 10, a camera 71 and a lighting component 73 mounted inside the mounting housing 72, and a nozzle 74 mounted on the inner wall of the color sorting slide 10; it also includes an air pump 9 for blowing air into the nozzle 74; a collection housing 6 is mounted on the inclined surface of the color sorting slide 10 near the base 17, the opening position of the collection housing 6 in the color sorting slide 10 corresponding to the opening position of the mounting housing 72 in the color sorting slide 10; the bottom of the collection housing 6... The inner wall of the collection housing 6 is inclined. A defective tea discharge pipe 12 is installed at the bottom of the collection housing 6 to discharge defective tea leaves sprayed into the collection housing 6 by the nozzle 74. A sieve plate 14 is installed at the opening of the defective tea discharge pipe 12 in the collection housing 6 to sieve the defective tea leaves sprayed into the collection housing 6. A guide plate 8 is installed on the inner wall of the color sorting chute 10 to guide the tea leaves that slide down the color sorting chute 10 and to block the opening of the collection housing 6 in the color sorting chute 10 to prevent the tea leaves that slide down the inner wall of the color sorting chute 10 from falling directly into the collection housing 6. A buffer mechanism 15 is provided inside the collection housing 6 to decelerate and buffer the defective tea leaves sprayed into the collection housing 6 by the nozzle 74. A movable mechanism 16 is provided inside the collection housing 6 to move the tea leaves that fall onto the sieve plate 14 when the nozzle 74 blows the defective tea leaves into the collection housing 6.
[0025] During use, tea leaves are fed from the storage housing 4 into the color sorting chute 10. As the tea leaves slide down the color sorting chute 10, the lighting unit 73 illuminates the sliding tea leaves, and the camera 71 films the tea leaves. When the camera 71 observes defective tea leaves, the nozzle 74 sprays air onto the defective tea leaves, blowing them into the collection housing 6. At this time, the buffer mechanism 15 slows down and buffers the defective tea leaves blown into the collection housing 6, preventing them from colliding with the inner wall of the collection housing 6 and breaking. The tea leaves that fall onto the screening plate 14 and are screened by the screening plate 14 fall into the defective product discharge pipe 12 for feeding. The large-sized tea leaves screened by the screening plate 14 slide down the bottom inner wall of the collection shell 6 to one end of the collection shell 6. In this way, the good tea leaves that are accidentally sprayed into the collection shell 6 during the color sorting process can be separated, thereby improving the color sorting effect. When the nozzle 74 sprays air, the moving mechanism 16 moves under the action of the airflow and moves the tea leaves that fall onto the screening plate 14, thereby improving the screening efficiency of the screening plate 14.
[0026] In a preferred embodiment of the present invention, a movable door 13 is movably installed at the end of the collecting shell 6 away from the color sorting slide 10. The movable door 13 can be opened to feed the large-sized tea leaves that have been screened by the screening plate 14.
[0027] As a preferred embodiment of the present invention, the buffer mechanism 15 includes an air outlet housing 152 installed on the inner wall of the collection housing 6. The position of the air outlet housing 152 corresponds to the position of the airflow ejected by the nozzle 74. An air outlet hole 151 is provided on the side of the air outlet housing 152 near the nozzle 74. The interior of the air outlet housing 152 is connected to the air outlet end of the air pump 9 through an air inlet pipe.
[0028] In a preferred embodiment of the present invention, the side of the air outlet housing 152 near the nozzle 74 is arc-shaped, which is used to guide the tea leaves blown to the side of the air outlet housing 152 to the top of the sieve plate 14. In use, the air pump 9 blows air into the air outlet housing 152, and the air in the air outlet housing 152 is ejected through the air outlet 151. The airflow rate ejected from the air outlet 151 is less than the airflow rate ejected from the nozzle 74. When the tea leaves are blown to the side of the air outlet housing 152 by the airflow ejected from the nozzle 74, the airflow ejected from the air outlet 151 blows the tea leaves in the opposite direction, slowing down the tea leaves and preventing the tea leaves from colliding with the side of the air outlet housing 152 at high speed and breaking.
[0029] In a preferred embodiment of the present invention, the movable mechanism 16 includes a fixed housing 163 installed on the inner wall of the top of the collecting housing 6. A vertically arranged rotating shaft 162 is movably installed on the side of the fixed housing 163 near the screening plate 14. A movable side wing 161 is installed on the side of the rotating shaft 162. The position of the movable side wing 161 corresponds to the position of the airflow ejected from the nozzle 74, which is used to increase the contact area between the rotating shaft 162 and the airflow ejected from the nozzle 74. When the nozzle 74 ejects gas, it drives the rotating shaft 162 to rotate. A rotating seat 167 is installed at the end of the rotating shaft 162 near the screening plate 14. A through hole 168 is opened on the rotating seat 167. A vertically arranged material feeding component 166 is movably arranged inside the through hole 168.
[0030] In a preferred embodiment of the present invention, a mounting wing 164 is installed at one end of the rotating shaft 162 inside the fixed housing 163. The side of the mounting wing 164 is connected to the inner wall of the fixed housing 163 through a return spring 165, which is used to pull the rotating shaft 162 to return to its original position when the nozzle 74 stops spraying air.
[0031] In a preferred embodiment of the present invention, the rotating shaft 162 is located between the air outlet housing 152 and the nozzle 74, and the bottom of the material feeding component 166 is in contact with the top of the sieve plate 14. When the nozzle 74 stops spraying air, the side of the movable wing 161 is perpendicular to the airflow direction of the nozzle 74. When the nozzle 74 sprays gas to spray the defective tea leaves into the collection housing 6, the movable wing 161 drives the rotating shaft 162 to rotate under the action of the high-speed airflow from the nozzle 74 until the movable wing 161 rotates to be parallel to the airflow direction of the nozzle 74. When the nozzle 74 stops spraying gas, the return spring 165 pulls the mounting wing 164, driving the rotating shaft 162 to rotate to the reset position. During the rotation of the rotating shaft 162, the material feeding component 166 drives the tea leaves on the sieve plate 14 to move, thereby improving the sieving effect of the sieve plate 14 on the tea leaves.
[0032] In a preferred embodiment of the present invention, the feeding component 166 is made of a flexible material.
[0033] In a preferred embodiment of the present invention, the feeding component 166 is made of materials such as rubber or silicone. In this embodiment, the feeding component 166 is preferably made of rubber.
[0034] In a preferred embodiment of the present invention, a feeding trough 2 is installed at the bottom of the storage shell 4 for transferring the tea leaves fed from the storage shell 4 to the top opening of the color sorting chute 10; a vibration component 5 is installed on the side of the storage shell 4 for driving the storage shell 4 and the feeding trough 2 to shake.
[0035] In a preferred embodiment of the present invention, a premium product discharge pipe 11 is provided at the end of the color sorting chute 10 away from the storage housing 4.
[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
