Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a screening machine for processing Forsythia black tea. Background Technology

[0002] Forsythia leaf black tea is a type of tea made primarily from forsythia leaves, a common traditional Chinese medicine that can be used both medicinally and as a beverage. Forsythia leaf black tea possesses properties that clear heat and detoxify, reduce inflammation, and have antibacterial effects. Its flavonoids effectively inhibit bacterial growth, providing adjunctive treatment for illnesses such as colds and pharyngitis. Furthermore, forsythia leaf black tea can lower blood lipids and prevent thrombosis, helping to prevent cardiovascular and cerebrovascular diseases. It also promotes intestinal peristalsis and digestion, helping to relieve gastrointestinal discomfort. Therefore, forsythia leaf black tea can be consumed as a health-promoting beverage in daily life.

[0003] Screening is an essential step in processing Forsythia leaf black tea to select leaves of the appropriate size. However, existing screening methods often involve manual screening, which is time-consuming, labor-intensive, and costly. Alternatively, simple sieve structures can be used, resulting in low efficiency and poor screening results. To address these shortcomings, we propose a screening machine for Forsythia leaf black tea processing. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a screening machine for processing Forsythia suspensa black tea. The Forsythia suspensa black tea raw materials are fed into the box through the feeding port. Two screen supports oscillate back and forth under the action of compression springs, thus screening and classifying the raw materials according to their different sizes. Simultaneously, the rotation of the rotating shaft drives the connecting rod to rotate, which in turn drives the sliding column to rotate. The sliding column, under the action of a fixed slide rail, drives the circular track and sliding rod to slide back and forth. The sliding of the sliding rod drives the arched frame to slide, which in turn drives the mounting rod and push rod to slide. The back-and-forth sliding of multiple push rods agitates the Forsythia suspensa black tea raw materials on the screen supports, facilitating better screening and classification, improving the screening effect of the machine, and saving labor costs. This effectively solves the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening machine for processing Forsythia black tea, comprising a housing, a first screen, a second screen, and screening components;

[0006] A discharge port is provided on the right side of the upper surface of the box body, and a first collection port is provided on the lower front side of the box body. Grooves are provided on the upper and lower left sides of the inside of the box body, and limit grooves are provided on the upper and lower right sides of the inside of the box body. There are two screen supports, and a second protrusion is installed on the right end of each screen support. A compression spring is installed on the upper and lower surfaces of the second protrusion. The two compression springs connected to the upper second protrusion are respectively connected to the upper and lower inner walls of the upper limit groove, and the two compression springs connected to the lower second protrusion are respectively connected to the upper and lower inner walls of the lower limit groove. A first protrusion is installed on the left end of each screen support. The upper first protrusion is rotatably connected to the upper groove through a first pin, and the lower first protrusion is rotatably connected to the lower groove through a second pin. A first screen is installed on the upper screen support, and a second screen is installed on the lower screen support. Both screen supports are lower on the left and higher on the right. A screening component is installed on the right side of the box body, and a collection component is installed on the left side of the box body.

[0007] Furthermore, the screening assembly includes a rotating shaft rotatably mounted on the right side of the housing, located between two screen supports. A fixed rod is mounted on the left end of the rotating shaft, and a connecting rod is mounted on the right end. A sliding column is mounted on the side of the end of the connecting rod. A fixed slide rail is mounted on the front right side of the housing, and a sliding rod is slidably mounted within the fixed slide rail. An annular track is mounted on the rear end of the sliding rod, and the sliding column is located within the annular track. A connecting rod is mounted on the front end of the sliding rod, and an arched frame is mounted on the inner side of the connecting rod. Both ends of the arched frame are slidably connected to the front side of the housing. Mounting rods are mounted on both ends of the arched frame, and multiple push rods are evenly mounted on the lower surface of the mounting rods. A drive assembly is mounted on the right side of the housing, and the drive assembly is connected to the rotating shaft. The fixed rod is longer than the vertical distance between the right ends of the two screen supports when they are stationary. The drive assembly rotates the shaft, which in turn rotates the fixed rod. During rotation, both ends of the fixed rod contact the right ends of the two screen supports, causing the screen supports to sway back and forth under the pressure of the springs. This screens the forsythia tea raw material. Simultaneously, the shaft rotation drives the connecting rod, which in turn drives the sliding column. The sliding column, under the action of the fixed slide rail, causes the circular track and sliding rod to slide back and forth. The sliding rod then drives the bow-shaped frame, which in turn drives the mounting rod and push rod to slide. The back-and-forth sliding of multiple push rods agitates the forsythia tea raw material on the screen supports, facilitating better screening and classification of the forsythia tea raw material and improving the screening effect of the screening machine.

[0008] Furthermore, the drive assembly includes a first belt and a first pulley mounted on a rotating shaft. A motor bracket is mounted on the right side of the housing, and a motor is mounted on the motor bracket. A rotating shaft is rotatably mounted on the right side of the housing. The output shaft of the motor is connected to one end of the rotating shaft via a coupling. A second pulley is mounted on the rotating shaft. The first pulley and the second pulley are connected via a first belt drive. The input end of the motor is electrically connected to the output end of an external controller. The external controller controls the motor's operation, which drives the rotating shaft to rotate. The rotation of the rotating shaft, under the action of the first pulley, the second pulley, and the first belt, drives the rotating shaft to rotate, thereby completing the rotation of the rotating shaft electrically.

[0009] Furthermore, the collection assembly includes a collection box detachably mounted on the left side of the housing. A discharge port is located on the left side of the housing, with the bottom surface of the discharge port horizontally aligned with the upper left surface of the screen support above. The top of the collection box is horizontally aligned with the bottom surface of the discharge port, and a second collection port is located on the lower left surface of the collection box. The forsythia black tea raw material screened by the first screen is collected through the collection box and discharged through the second collection port.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This screening machine for processing Forsythia suspensa black tea firstly feeds the Forsythia suspensa black tea raw materials into the box through the feeding port. Two screen supports oscillate back and forth under the action of compression springs, thus screening and classifying the Forsythia suspensa black tea raw materials according to different sizes. Simultaneously, the rotating shaft drives the connecting rod to rotate, which in turn drives the sliding column to rotate. The sliding column, under the action of the fixed slide rail, drives the circular track and sliding rod to slide back and forth. The sliding rod drives the bow-shaped frame to slide, which in turn drives the mounting rod and push rod to slide. Thus, the back-and-forth sliding of multiple push rods agitates the Forsythia suspensa black tea raw materials on the screen supports, facilitating better screening and classification of the raw materials, improving the screening effect of the screening machine, and ultimately saving labor costs.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2 This embodiment provides a technical solution: a screening machine for processing Forsythia black tea, including a housing 1, a first screen 21, a second screen 27, and screening components;

[0016] A discharge port 2 is provided on the right side of the upper surface of the box body 1, and a first collection port 10 is provided on the lower front side of the box body 1. Grooves are provided on the upper and lower left sides of the interior of the box body 1, and limit grooves 24 are provided on the upper and lower right sides of the interior of the box body 1. Two screen supports 22 are provided, and a second protrusion is installed on the right end of each of the two screen supports 22. Compression springs 23 are installed on the upper and lower surfaces of the second protrusions. The two compression springs 23 connected to the upper second protrusion are respectively connected to the upper and lower inner walls of the upper limit groove 24, and the two compression springs 23 connected to the lower second protrusion are respectively connected to the upper and lower inner walls of the limit groove 24. 3 are respectively connected to the upper and lower inner walls of the lower limiting groove 24. The left ends of the two screen supports 22 are each equipped with a first protrusion 18. The upper first protrusion 18 is rotatably connected to the upper groove through the first pin, and the lower first protrusion 18 is rotatably connected to the lower groove through the second pin. The upper screen support 22 is equipped with a first screen 21, and the lower screen support 22 is equipped with a second screen 27. The left end of both screen supports 22 is lower and the right end is higher. The screening component is installed on the right side of the box 1, and the collection component is installed on the left side of the box 1.

[0017] First, the forsythia black tea raw material is put into the box 1 through the feeding port 2. The sieve holes of the first screen 21 are larger than those of the second screen 27. After the screening component works, the two screen supports 22 shake, so that the forsythia black tea raw material is screened and classified according to different sizes under the screening action of the first screen 21 and the second screen 27.

[0018] The screening assembly includes a rotating shaft 26 rotatably mounted on the right side of the housing 1. The rotating shaft 26 is located between two screen supports 22. A fixed rod 25 is installed at the left end of the rotating shaft 26, and a connecting rod 5 is installed at the right end of the rotating shaft 26. A sliding column 4 is installed on the side of the end of the connecting rod 5. A fixed slide rail 12 is installed at the front right side of the housing 1. A sliding rod 6 is slidably installed in the fixed slide rail 12. An annular track 3 is installed at the rear end of the sliding rod 6. The sliding column 4 is located in the annular track 3. A connecting rod 11 is installed at the front end of the sliding rod 6. An arc-shaped frame 9 is installed on the inner side of the connecting rod 11. The two ends of the arc-shaped frame 9 are slidably connected to the front side of the housing 1. Mounting rods 19 are installed at both ends of the arc-shaped frame 9. Multiple push rods 20 are evenly installed on the lower surface of the mounting rods 19. A drive assembly is installed on the right side of the housing 1. The drive assembly is connected to the rotating shaft 26. The length of the fixed rod 25 is greater than the vertical distance between the right ends of the two screen supports 22 when they are stationary. The drive assembly drives the rotating shaft 26 to rotate, which in turn drives the fixed rod 25 to rotate. During the rotation, the two ends of the fixed rod 25 abut against the right ends of the two screen supports 22, causing the screen supports 22 to sway back and forth under the action of the compression spring 23, thereby screening the forsythia black tea raw materials. At the same time, the rotation of the rotating shaft 26 drives the connecting rod 5 to rotate, which in turn drives the sliding column 4 to rotate. The movement of the sliding column 4, under the action of the fixed slide rail 12, drives the annular track 3 and the sliding rod 6 to slide back and forth. The sliding of the sliding rod 6 drives the bow frame 9 to slide, which in turn drives the mounting rod 19 and the push rod 20 to slide. Thus, the back and forth sliding of multiple push rods 20 stirs the forsythia black tea raw materials on the screen supports 22, so as to better screen and classify the forsythia black tea raw materials, improve the screening effect of the screening machine, and save labor costs.

[0019] The drive assembly includes a first belt 8 and a first pulley 7 mounted on a rotating shaft 26. A motor bracket 15 is mounted on the right side of the housing 1, and a motor 14 is mounted on the motor bracket 15. A rotating shaft is rotatably mounted on the right side of the housing 1. The output shaft of the motor 14 is connected to one end of the rotating shaft via a coupling. A second pulley 13 is mounted on the rotating shaft. The first pulley 7 and the second pulley 13 are connected by a first belt 8. The input end of the motor 14 is electrically connected to the output end of an external controller. The external controller controls the operation of the motor 14. The operation of the motor 14 drives the rotating shaft to rotate. The rotation of the rotating shaft, under the action of the first pulley 7, the second pulley 13, and the first belt 8, drives the rotating shaft 26 to rotate, thereby completing the rotation of the rotating shaft 26 electrically.

[0020] The collection assembly includes a collection box 17 detachably mounted on the left side of the housing 1. A discharge port is located on the left side of the housing 1, with the bottom surface of the discharge port horizontally aligned with the upper left surface of the screen support 22 above. The top of the collection box 17 is horizontally aligned with the bottom surface of the discharge port. A second collection port 16 is located on the lower left surface of the collection box 17. The forsythia black tea raw material screened by the first screen 21 is collected through the collection box 17 and discharged through the second collection port 16.

[0021] The working principle of the screening machine for processing Forsythia black tea provided by this utility model is as follows: First, the Forsythia black tea raw material is put into the box 1 through the feeding port 2. The screen holes of the first screen 21 are larger than those of the second screen 27. After the screening component works, it drives the two screen supports 22 to shake. Thus, under the screening action of the first screen 21 and the second screen 27, the Forsythia black tea raw materials of different sizes are screened and classified. The length of the fixed rod 25 is greater than the vertical distance between the right ends of the two screen supports 22 when they are stationary. The drive assembly drives the rotating shaft 26 to rotate, which in turn drives the fixed rod 25 to rotate. During the rotation, the two ends of the fixed rod 25 abut against the right ends of the two screen supports 22, causing the screen supports 22 to sway back and forth under the action of the compression spring 23, thereby screening the forsythia black tea raw materials. At the same time, the rotation of the rotating shaft 26 drives the connecting rod 5 to rotate, which in turn drives the sliding column 4 to rotate. The movement of the sliding column 4, under the action of the fixed slide rail 12, drives the annular track 3 and the sliding rod 6 to slide back and forth. The sliding of the sliding rod 6 drives the bow frame 9 to slide, which in turn drives the mounting rod 19 and the push rod 20 to slide. Thus, the back and forth sliding of multiple push rods 20 stirs the forsythia black tea raw materials on the screen supports 22, so as to better screen and classify the forsythia black tea raw materials, improve the screening effect of the screening machine, and save labor costs. The motor 14 is controlled by an external controller, which drives the rotating shaft to rotate. The rotating shaft, under the action of the first pulley 7, the second pulley 13, and the first belt 8, drives the rotating shaft 26 to rotate, thus completing the rotation of the rotating shaft 26 electrically. The forsythia black tea raw material screened by the first screen 21 is collected by the collection box 17 and discharged through the second collection port 16.

[0022] It is worth noting that in this embodiment, the core chip of the external controller is an STC microcontroller, specifically the STC15W204S. The motor 14 can be freely configured according to the actual application scenario, and can be a JE series single-phase servo motor manufactured by Beijing Mitsubishi Electric (China) Co., Ltd. The external controller controls the operation of the motor 14 using methods commonly used in the prior art, and any content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
