Description

Technical Field

[0001] This utility model relates to the field of black tea processing technology, and in particular to a black tea processing impurity removal and screening structure. Background Technology

[0002] Black tea refers to tea made from suitable tea leaves through a series of processes including withering, rolling, fermentation, and drying. The fermentation process causes chemical reactions in the tea leaves, resulting in a unique deep red color when brewed with water. Hence, it is called "black tea".

[0003] An existing black tea processing impurity removal screening structure (publication number: CN220406302U) has at least the following drawbacks: This device, through the setting of a screening mechanism, allows a servo motor one to push a movable plate one via a protrusion, causing the movable spring to retract under pressure. When the protrusion separates from the movable plate one, the movable plate two will reset the top movable frame under the action of the movable spring's rebound force. This cycle can achieve the left-right reciprocating motion of the screen. The servo motor two can drive the bottom movable frame to rotate. The setting of two screens greatly improves the impurity removal screening effect. However, only the screen moves left and right, which is not convenient for collecting the screened material and debris, and is not conducive to disassembling and cleaning the screen, causing inconvenience to the staff and resulting in less than ideal performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sieving structure for removing impurities in black tea processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A black tea processing impurity removal sieving structure includes a sieving box and a sieving container, characterized in that: a fixed frame is provided inside the sieving box, an mounting block is provided on the fixed frame, an inner groove is opened on the mounting block, a tension spring is installed inside the inner groove, a movable block is provided at the end of the tension spring away from the inner wall of the inner groove, a positioning post is provided on the movable block, a top frame is installed above the fixed frame, and a collection box is installed below the sieving container, the collection box being slidably connected to the sieving box.

[0007] As a further embodiment of this utility model, a base frame is provided at the bottom end of the top frame, the fixed frame is slidably connected to the base frame, a support base plate is installed at the bottom end of the base frame, the support base plate is fixedly connected to the interior of the screening box, and a sealing plate is installed at the top of the screening box.

[0008] As a further embodiment of this utility model, a discharge port is provided on the sealing plate, and a second motor is provided between the bottom of the supporting base plate and the interior of the screening box. The second motor is connected to the interior of the screening box by fasteners. The second motor is symmetrically distributed in the screening box. The sealing plate is connected to the top of the screening box by hinges.

[0009] As a further embodiment of this utility model, a buffer spring 2 is installed between one end of the fixed frame and the interior of the base frame, and a motor 1 is installed on the base frame. The motor 1 is connected to the buffer spring 2 by fasteners, and the motor 1 is located on one side of the fixed frame.

[0010] As a further embodiment of this utility model, a buffer spring is provided between the top of the top frame and the interior of the screening box. The two ends of the buffer spring are fixedly connected to the top of the top frame and the screening box, and the two ends of the tension spring are respectively fixedly connected to the movable block and the interior of the inner groove.

[0011] As a further embodiment of this utility model, a locking block is installed on the screening box, one end of the positioning column is fixedly connected to the movable block, the end of the positioning column away from the movable block is fitted and connected to the screening box, and the movable block is slidably connected to the inner groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. To enhance the screening effect, several screening boxes are installed inside the screening chamber. Material is poured into these boxes to prevent accumulation and maintain screening efficiency. Motor 1 is started, and its output shaft drives a telescopic rod to push a fixed frame reciprocating within the base frame, vibrating and screening the material from side to side. Simultaneously, Motor 2 is started, driving a telescopic rod through the supporting base plate, pushing the base frame and the fixed frame up and down, vibrating and screening the material from top to bottom, thus enhancing the screening effect. After screening, the sealing plate can be pulled upwards to process the material in the screening boxes. The collection box can be slid out of the screening chamber for separate processing of collected impurities. Furthermore, the use of buffer springs 1 and 2, through compression, allows the buffer springs to absorb vibration energy through elastic deformation, improving overall stability and facilitating the screening process.

[0014] 2. Two sets of positioning columns are installed on the fixed frame. Pushing the screening box into the groove of the fixed frame and pulling the movable block causes the tension spring to deform, thereby pushing the positioning column into the positioning hole on the locking block. After the tension spring is loosened, under the elastic action of the tension spring, the two sets of positioning columns are forced to lock and fix the screening box on the fixed frame, which facilitates the installation and disassembly of the screening box and improves its practicality.

[0024] Reference Figures 1-5 A black tea processing impurity removal sieving structure includes a sieving box 1 and a sieving box 4. The sieving box 1 is characterized by: a fixed frame 105 inside the sieving box 1, an mounting block 6 on the fixed frame 105, an inner groove 8 on the mounting block 6, a tension spring 7 installed inside the inner groove 8, a movable block 801 at the end of the tension spring 7 away from the inner wall of the inner groove 8, a positioning post 802 on the movable block 801, a top frame 103 installed above the fixed frame 105, and a collection box 3 installed below the sieving box 4, the collection box 3 being slidably connected to the sieving box 1.

[0025] In use, to enhance the screening effect, several screening boxes 4 are installed inside the screening chamber 1. Material is poured into these boxes to prevent accumulation and ensure effective screening. Motor 1 201 is started, and its output shaft drives the telescopic rod to push the fixed frame 105 back and forth within the base frame 106, vibrating and screening the material. Simultaneously, motor 203 is started, driving the telescopic rod through the supporting base plate 202, pushing the base frame 106 and causing the fixed frame 105 to move up and down, further vibrating and screening the material. The vertical vibrating screen enhances the screening effect. After screening, the sealing plate 101 can be pulled up to process the material in the screening box 4. The collection box 3 can be pulled to slide out of the screening box 1, allowing for separate processing of collected impurities. Under the action of buffer spring 102 and buffer spring 204, the energy of vibration is absorbed by the buffer spring 102 and buffer spring 204 through elastic deformation, which improves the overall stability and is beneficial to screening processing.

[0026] In this embodiment, a base frame 106 is provided at the bottom end of the top frame 103, and a fixed frame 105 is slidably connected to the base frame 106. A support base plate 202 is installed at the bottom end of the base frame 106. The support base plate 202 is fixedly connected to the interior of the screening box 1, and a sealing plate 101 is installed at the top of the screening box 1.

[0027] In use, two sets of positioning posts 802 are installed on the fixed frame 105. Pushing the screening box 4 to fit into the groove of the fixed frame 105, pulling the movable block 801 causes the tension spring 7 to deform, thereby pushing the positioning posts 802 to fit into the positioning holes opened on the locking block 5. After the tension spring 7 is loosened, under the elastic action of the tension spring 7, the two sets of positioning posts 802 are forced to lock and fix the screening box 4 on the fixed frame 105, which facilitates the installation and disassembly of the screening box 4 and improves its practicality.

[0028] In this embodiment, a discharge port 2 is provided on the sealing plate 101, and a motor 203 is provided between the bottom of the supporting base plate 202 and the inside of the screening box 1. The motor 203 is connected to the inside of the screening box 1 by fasteners. The motors 203 are symmetrically distributed inside the screening box 1, and the sealing plate 101 is connected to the top of the screening box 1 by hinges.

[0029] During use, a support base plate 202 is installed at the bottom of the base frame 106. The support base plate 202 is mainly made of rubber. The support base plate 202 provides support and limit for the base frame 106 to prevent the base frame 106 from falling off.

[0030] In this embodiment, a buffer spring 104 is installed between one end of the fixed frame 105 and the interior of the base frame 106. A motor 201 is installed on the base frame 106. The motor 201 is connected to the buffer spring 104 by fasteners. The motor 201 is located on one side of the fixed frame 105.

[0031] In use, buffer spring 102 and buffer spring 204 are made of plastic. When buffer spring 102 and buffer spring 204 are squeezed, they absorb the energy of vibration by generating elastic deformation, thereby slowing down the movement and improving the overall stability.

[0032] In this embodiment, a buffer spring 102 is provided between the top of the top frame 103 and the inside of the screening box 1. The two ends of the buffer spring 102 are fixedly connected to the top of the top frame 103 and the screening box 1, and the two ends of the tension spring 7 are fixedly connected to the movable block 801 and the inside of the inner groove 8, respectively.

[0033] In use, motor 1 201 and motor 2 203 are telescopic motors, with the main model being 20N3812-1. The collection box 3 is used to collect impurities generated during screening. By pulling the collection box 3, the operator can slide it out of the screening box 1 and process the collected impurities separately.

[0034] In this embodiment, a locking block 5 is installed on the screening box 4, one end of the positioning column 802 is fixedly connected to the movable block 801, the other end of the positioning column 802 away from the movable block 801 is fitted and connected to the screening box 4, and the movable block 801 is slidably connected to the inner groove 8.

[0035] In use, several screening boxes 4 are installed inside the screening box 1. The screening boxes 4 have filter holes that are evenly spaced. By pouring the material into the screening boxes 4, the material accumulation is avoided, which affects the screening effect. At the same time, it is convenient to process the screened material.

[0036] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In order to enhance the screening effect of materials, several screening boxes 4 are installed in the screening box 1. The material is poured into several screening boxes 4 to avoid material accumulation affecting the screening effect. Motor 1 201 is started. Motor 1 201 drives the telescopic rod through the output shaft to push the fixed frame 105 to reciprocate within the base frame 106, performing left and right vibration screening of the material. At the same time, motor 203 is started. Motor 203 drives the telescopic rod through the support base plate 202, pushing the base frame 106 to drive the fixed frame 105 to move up and down, which can perform up and down vibration screening of the material, enhancing the vibration screening effect. After screening, the sealing plate 101 is pulled up to process the material in the screening box 4. The collection box 3 is pulled to slide out of the screening box. The housing 1 allows for separate processing of collected impurities. Under the action of buffer springs 102 and 104, the energy of vibration is absorbed by the elastic deformation of buffer springs 102 and 104 through compression, improving overall stability and facilitating screening. Two sets of positioning posts 802 are installed on the fixed frame 105. Pushing the screening box 4 into the groove of the fixed frame 105 and pulling the movable block 801 causes the tension spring 7 to deform, thereby pushing the positioning posts 802 into the positioning holes on the locking block 5. After the tension spring 7 is loosened, the two sets of positioning posts 802 are forced to lock the screening box 4 onto the fixed frame 105 under the elastic action of the tension spring 7, facilitating the installation and disassembly of the screening box 4 and improving its practicality.
