Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea blank screening technology, and in particular to a pretreatment screening device for non-green tea blanks used in jasmine scenting. Background Technology
[0002] Jasmine tea is a traditional reprocessed tea. Its production process mainly includes tea base treatment, fresh flower care, scenting, ventilation and heat dissipation, flower removal, and baking. Among these steps, the pretreatment of the tea base is particularly crucial, especially for non-green tea bases, which require more refined sieving before scenting due to their different physical properties compared to green tea.
[0003] Currently, the industry mainly relies on manual labor or general screening equipment for screening non-green tea leaves. However, these methods suffer from low efficiency and uneven screening, making it difficult to meet the production requirements of high-quality jasmine tea. The commonly used screening methods in the industry include: 1) Manual screening, which involves manually shaking the screen to grade the tea leaves. However, this method is labor-intensive, inefficient, and its screening effect is greatly affected by human factors. 2) Mechanical vibratory screening, which uses a motor to drive the screen to vibrate. However, general mechanical vibratory screens are poorly adapted to non-green tea leaves, easily causing breakage or incomplete screening. 3) Airflow screening, which uses airflow to separate tea leaves according to particle size. However, this method requires a high moisture content in the tea leaves and the equipment is expensive. Each of these methods has its advantages and disadvantages, but none can fully meet the requirements for refined screening of non-green tea leaves before jasmine scenting. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a pretreatment sieving device for non-green tea tea blanks in jasmine scenting, aiming to improve the problem that the existing technology cannot fully meet the fine sieving requirements of non-green tea tea blanks before jasmine scenting.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pretreatment sieving device for non-green tea tea blanks scented with jasmine flowers, comprising a base, with columns fixedly connected to the front and rear sides of the top left end of the base, two adjacent columns rotatably connected to the same fixed plate, a sieving mechanism provided on the top of the fixed plate, a lifting mechanism provided on the top right side of the base, a support frame fixedly connected to the left side of the base, a feeding mechanism provided on the top of the support frame, and a reinforcing mechanism provided on the outside of the feeding mechanism; the sieving mechanism comprises a sieving box, with multiple mounting grooves on the upper and lower sides of the inner wall of the sieving box, sieving plates slidably connected to the inner walls of the multiple mounting grooves, soft pads fixedly connected to the tops of the multiple sieving plates, multiple sieve holes provided on the outer walls of the multiple sieving plates and the soft pads, multiple protrusions fixedly connected to the tops of the multiple soft pads, and guide boxes fixedly connected to the right sides of the outer walls of the multiple sieving plates; a driving component provided on the top of the support frame, and a sliding component provided on the bottom of the sieving box.
[0006] Through the above technical solution: the base provides stable support for the entire device, and the column at its top left supports the fixed plate, allowing the fixed plate to rotate and adjust its angle to adapt to different screening requirements. The feeding mechanism is located at the top of the support frame and consists of a vertical plate, a horizontal plate, and a hopper. The non-green tea jasmine flowers to be screened are placed into the hopper. Supported by the vertical and horizontal plates, the jasmine flowers fall onto the uppermost screening plate in the screening box of the screening mechanism at the top of the fixed plate. At this time, the drive component starts to work. The motor is fixed at the top of the support frame, and its output end drives the rotating wheel to rotate. The rotating wheel pushes the screening box to sway left and right through the rocker arm. In the sliding component at the bottom of the screening box, the pulley slides in the sliding groove at the top of the fixed plate to ensure the stability of the screening box. Inside the movable screening box, the mounting groove slides into the screening plate, causing the screening plate to sway. The soft pad on top of the screening plate absorbs shock and prevents damage to the jasmine flowers. The screen holes are used for screening, and the protrusions increase the contact and friction between the jasmine flowers and the screening plate, making the screening more thorough. The jasmine flowers screened through the upper screening plate fall through the screen holes into the lower screening plate for further screening. Finally, the screened jasmine flowers fall into the guide box on the right side of the screening plate for collection. The lifting mechanism can be adjusted by rotating the handle, which moves the threaded column up and down inside the hollow shell, thereby adjusting the tilt angle of the fixed plate and optimizing the screening effect. The reinforcement mechanism enhances the stability of the feeding mechanism through the reinforcing rod, mounting plate, and screws, ensuring the smooth operation of the entire screening process.
[0007] As a further description of the above technical solution:
[0008] The lifting mechanism includes two hollow shells. A threaded column is slidably connected to the top of the inner wall of each hollow shell. Limit blocks are fixedly connected to the left and right sides of the bottom of the outer wall of each threaded column. Limit grooves are formed on the left and right sides of the inner wall of each hollow shell. Multiple limit blocks are slidably connected to their respective limit grooves. A rotating seat is fixedly connected to the top of each threaded column. A second sliding groove is formed on the front and rear sides of the bottom right end of the screening box. A sliding seat is slidably connected to the inner wall of each of the two second sliding grooves. The two sliding seats are rotatably connected to their respective rotating seats. A rotating handle is rotatably connected to the outer wall of each hollow shell. The inner wall of each rotating handle is threadedly connected to the outer wall of its respective threaded column.
[0009] Through the above technical solution: when adjustment is needed, the operator rotates the handle. Since the inner wall of the handle is threadedly connected to the outer wall of the threaded column, and the handle is rotatably connected to the outer wall of the hollow shell, the rotation of the handle causes the threaded column to move axially. During this process, the limiting blocks on the left and right sides of the bottom of the outer wall of the threaded column are slidably connected to the limiting grooves on the left and right sides of the inner wall of the hollow shell. This structure ensures that the threaded column can only move stably in the up and down direction within the hollow shell, avoiding deviation or shaking during rotation. As the threaded column moves up and down within the hollow shell, the rotating seat, which is fixedly connected to its top, also moves up and down synchronously. The sliding seat is slidably connected to the sliding groove two on the front and rear sides of the bottom right end of the screening box, and the sliding seat is rotatably connected to the rotating seat. Therefore, the up and down movement of the rotating seat causes the sliding seat to slide left and right within the sliding groove two. The sliding of the sliding seat causes a change in height at the right end of the screening box, thereby changing the tilt angle of the fixed plate. This allows for flexible and precise adjustment of the tilt angle according to the characteristics of non-green tea jasmine flowers and actual screening requirements, optimizing the screening effect.
[0010] As a further description of the above technical solution:
[0011] The drive assembly includes a motor, the bottom of which is fixedly connected to the top of the support frame. A wheel is fixedly connected to the output end of the motor, and a rocker arm is rotatably connected to the front side of the outer wall of the wheel. The right end of the rocker arm is rotatably connected to the screening box.
[0012] Through the above technical solution: when the drive component is working, the motor is fixed to the top of the support frame. After starting, the output end drives the wheel to rotate. The rocker connected to the front side of the outer wall of the wheel rotates with it, converting the circular motion into linear push-pull motion, which in turn drives the screening box connected to it to sway left and right, thereby realizing the screening of jasmine flowers.
[0013] As a further description of the above technical solution:
[0014] The sliding assembly includes multiple pulleys, the tops of which are fixedly connected to the four corners of the bottom of the screening box. The top front and rear sides of the fixed plate are provided with a sliding groove, and the multiple pulleys are slidably connected to the corresponding sliding groove.
[0015] Through the above technical solution: when the sliding component is working, the top of the pulley is fixed at the four corners of the bottom of the screening box. When the screening box needs to be moved by external force, the pulley slides in the top groove of the fixed plate to reduce friction and allow the screening box to move smoothly and steadily in the predetermined direction on the fixed plate.
[0016] As a further description of the above technical solution:
[0017] The feeding mechanism includes a vertical plate, the bottom end of which is fixedly connected to the top left side of the support frame, a horizontal plate is fixedly connected to the top of the vertical plate, and a hopper is fixedly connected to the right side of the outer wall of the horizontal plate.
[0018] Through the above technical solution: when the feeding mechanism is working, the bottom end of the vertical plate is firmly connected to the top left side of the support frame, and the top is connected to the horizontal plate to maintain the structure. The hopper connected to the right side of the horizontal plate holds the non-green tea tea blanks and jasmine flowers to be screened. The flowers fall naturally by gravity and are sent to the screening mechanism for processing.
[0019] As a further description of the above technical solution:
[0020] The reinforcement mechanism includes a reinforcing rod, both ends of which are fixedly connected to mounting plates. Screws are threaded onto the outer walls of both mounting plates. Multiple screws on the left side are threaded onto the vertical plate, and the tops of multiple screws on the right side are threaded onto the horizontal plate.
[0021] Through the above technical solution: when the reinforcement mechanism is working, the mounting plates at both ends of the reinforcing rod are connected to the vertical plate and the horizontal plate respectively by screws. Tightening the screws will make the reinforcing rod pull the vertical plate and the horizontal plate together, thereby enhancing the overall stability of the feeding mechanism and preventing it from shaking or deforming during operation.
[0022] As a further description of the above technical solution:
[0023] The screening box has a reserved groove at the bottom of its inner wall. A collection box is slidably connected to the inner wall of the reserved groove. Guide grooves are provided on the front and back sides of the inner wall of the reserved groove. Slider blocks are fixedly connected to the front and back sides of the outer wall of the collection box. The two guide grooves are slidably connected to the corresponding sliders.
[0024] With the above technical solution: when the screening box is working, the reserved groove is at the bottom of its inner wall, the collection box is placed in it, the slider on the outer wall of the collection box is slidably connected to the guide groove on the inner wall of the reserved groove, the screened material falls into the collection box, and after it is full, the collection box can be smoothly pulled out along the guide groove, which is convenient for cleaning and transferring materials.
[0025] As a further description of the above technical solution:
[0026] A support frame is fixedly connected to the top left side of the screening box, and multiple dispersing rods are fixedly connected to the bottom front and rear sides of the support frame.
[0027] Through the above technical solution: when the screening box is running, the top left support frame supports the dispersing rod. When the material is poured in, the dispersing rod disperses it to avoid accumulation and facilitates subsequent screening.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the motor, wheel and rocker arm of the drive component work together to drive the sieving box to shake. The sliding component ensures the stable movement of the sieving box. The sieving plate works with the soft pad and protrusions to achieve fine sieving, shock absorption and full turning of the jasmine flowers. Finally, the guide box facilitates collection. These structures work closely together to effectively improve the problem that the existing technology cannot fully meet the problem of fine sieving of non-green tea tea blanks before jasmine flower scenting.
[0030] 2. In this utility model, the threaded connection between the rotating handle and the threaded column, and the support of the hollow shell on the rotating handle, enable the threaded column to move axially when the rotating handle rotates. The sliding connection between the limiting block and the limiting groove ensures the stable up-and-down movement of the threaded column. The rotating seat moves synchronously with the threaded column, driving the sliding seat to slide in the second sliding groove, changing the height of the right end of the screening box, thereby flexibly and accurately adjusting the tilt angle of the fixed plate. This effectively optimizes the screening effect and makes up for the shortcomings of the existing technology in screening non-green tea tea leaves and jasmine flowers, which cannot accurately adjust the angle according to the characteristics of the raw materials and actual requirements to achieve fine screening.

A rocker arm 2083 is rotatably connected to the front side of the outer wall of the rotating wheel 2082, converting the circular motion of the rotating wheel 2082 into linear motion, thereby causing the screening box 201 to shake. The right end of the rocker arm 2083 is connected to the screening box 201. 1. Rotary connection; The feeding mechanism 7 includes a vertical plate 701, which serves as one of the supporting structures of the feeding mechanism 7. Its function is to support the horizontal plate 702 and the hopper 703, so that the feeding mechanism 7 has a certain height. The bottom end of the vertical plate 701 is fixedly connected to the top left side of the support frame 6. The top of the vertical plate 701 is fixedly connected to the horizontal plate 702, which provides an installation foundation for the hopper 703 and further enhances the structural stability of the feeding mechanism 7. The outer right side of the horizontal plate 702 is fixedly connected to the hopper 703, which holds the non-green tea tea blank jasmine flowers to be screened and guides the jasmine flowers smoothly into the screening mechanism 2.
[0041] Specifically, the base 1 provides stable support for the entire device. The column 4 at the top left end connects to and supports the fixing plate 5, allowing it to rotate. The fixing plate 5 carries the screening mechanism 2, providing a platform for screening operations. In the screening mechanism 2, the mounting groove 202 in the screening box 201 is slidably connected to the screening plate 203 for easy installation and replacement. The soft pad 204 on the screening plate 203 dampens and protects the jasmine flowers. The sieve holes 205 are used for screening, and the protrusions 206 assist in thorough screening. The guide box 207 facilitates the collection of the screened jasmine flowers. The motor 2081 of the drive assembly 208 is fixed to the top of the support frame 6. After starting, it drives the rotating wheel 2082 to rotate, and pushes the screening box 201 left and right through the rocker arm 2083. The swaying mechanism enables the jasmine flowers to be screened. The pulley 2091 of the sliding component 209 cooperates with the sliding groove 2092 on the fixed plate 5 to ensure the smooth sliding of the screening box 201.

All the components work together to solve the problem of fine screening of non-green tea tea blanks before jasmine flower scenting.
[0042] Reference Figure 3 , Figure 5 and Figure 6The lifting mechanism 3 includes two hollow shells 301, providing installation space and support structure for components such as threaded columns 302. Threaded columns 302 are slidably connected to the top of the inner walls of both hollow shells 301. Their function is to adjust the height of connected components by moving up and down. Limit blocks 303 are fixedly connected to the left and right sides of the bottom outer walls of both threaded columns 302, cooperating with limit grooves 304 to restrict the movement direction of the threaded columns 302, ensuring that they can only move up and down along the axial direction of the hollow shells 301. The inner walls of the two hollow shells 301 are provided with limiting grooves 304 on the left and right sides, which are slidably connected to the limiting blocks 303. These grooves guide and limit the movement of the threaded column 302, ensuring the stability of its movement. Multiple limiting blocks 303 are slidably connected to their corresponding limiting grooves 304, ensuring that the threaded column 302 can move up and down while preventing it from shifting or shaking during movement. The tops of the two threaded columns 302 are fixedly connected to rotating seats 305, which connect the threaded column 302 to the slide 307 and allow the slide 307 to rotate. To accommodate different movement requirements of the screening box 201, the bottom right end of the screening box 201 is provided with two sliding grooves 306 on both the front and rear sides, providing sliding tracks for the slide blocks 307, allowing the slide blocks 307 to slide smoothly within them. The inner walls of both sliding grooves 306 are slidably connected to the slide blocks 307, which slide along the sliding grooves 306 under the drive of the threaded column 302, thereby changing the height or tilt angle of the screening box 201. The two slide blocks 307 are respectively rotatably connected to the corresponding rotating seats 305, converting the up-and-down movement of the threaded column 302 into the movement of the slide blocks. 307 slides within the chute 306, while allowing the slide block 307 to rotate relative to the rotating seat 305, thereby adjusting the position of the screening box 201. The outer walls of the two hollow shells 301 are rotatably connected to a handle 308, providing a force point for the operator to drive the threaded column 302 by rotating the handle 308. The inner walls of the two handles 308 are threadedly connected to the outer walls of the corresponding threaded columns 302, converting the rotation of the handles 308 into the up-and-down movement of the threaded columns 302, thereby realizing the manual operation and control of the lifting mechanism 3.
[0043] Specifically, the hollow shell 301 serves as a basic support component, fixed at a specific position in the device to provide a mounting base for other components. The threaded column 302 is slidably connected to the top of the inner wall of the hollow shell 301, and the limiting block 303 at the bottom of its outer wall and the limiting groove 304 on the inner wall of the hollow shell 301 are slidably engaged, restricting the movement trajectory of the threaded column 302 so that it can only move up and down along the axial direction of the hollow shell 301, ensuring the stability and accuracy of the adjustment process. The rotating handle 308 is threadedly connected to the outer wall of the threaded column 302 and rotatably connected to the outer wall of the hollow shell 301. When the rotating handle 308 is rotated, the threaded column 302 is driven to move up and down within the hollow shell 301 using the principle of threaded transmission. The rotating seat 305 at the top of 302 moves synchronously with the threaded column 302. The rotating seat 305 is rotatably connected to the slide seat 307 in the second slide groove 306 at the bottom of the screening box 201. Therefore, the up and down movement of the threaded column 302 is transmitted through the rotating seat 305, which drives the slide seat 307 to slide left and right in the second slide groove 306. The sliding of the slide seat 307 in the second slide groove 306 changes the height of the right end of the screening box 201, thereby adjusting the tilt angle of the fixed plate 5. Through such close cooperation of various components, the height of the screening box 201 and the tilt of the fixed plate 5 can be flexibly and accurately adjusted to adapt to the different screening requirements of non-green tea tea leaves and jasmine flowers, thereby improving the screening effect and efficiency.
[0044] Reference Figure 2 , Figure 3 and Figure 4 The sliding component 209 includes multiple pulleys 2091. The tops of the multiple pulleys 2091 are fixedly connected to the four corners of the bottom of the screening box 201. The top front and rear sides of the fixed plate 5 are provided with sliding grooves 2092. The multiple pulleys 2091 are slidably connected to the corresponding sliding grooves 2092. The cooperation between the pulleys 2091 and the sliding grooves 2092 reduces the friction when the screening box 201 moves, ensuring that the screening box 201 can swing smoothly and steadily from side to side on the fixed plate 5, which helps the jasmine flower screening work to be carried out effectively.
[0045] Specifically, the tops of multiple pulleys 2091 are fixed to the four corners of the bottom of the screening box 201. When the screening box 201 needs to move under the action of the drive component 208, the pulleys 2091 slide in the first groove 2092 opened on the front and rear sides of the top of the fixed plate 5. The pulleys 2091 cooperate with the first groove 2092 to reduce the friction when the screening box 201 moves, ensuring that the screening box 201 can swing smoothly and steadily from side to side on the fixed plate 5, which helps the jasmine flower screening work to be carried out effectively.
[0046] Reference Figure 1 , Figure 2 and Figure 3The reinforcing mechanism 8 includes a reinforcing rod 801, which enhances the overall stability of the feeding mechanism 7. Both ends of the reinforcing rod 801 are fixedly connected to mounting plates 802, providing installation positions for connection with other components. Screws 803 are threaded onto the outer walls of both mounting plates 802. Multiple screws 803 on the left side are threaded onto the vertical plate 701, achieving a tight connection between the reinforcing mechanism 8 and the feeding mechanism 7 by tightening the screws 803. The tops of multiple screws 803 on the right side are threaded onto the horizontal plate 702. A reserved groove 9 is provided at the bottom of the inner wall of the screening box 201 to provide space for the collection box 10. The inner wall of the reserved groove 9... A collection box 10 is slidably connected to the wall to collect the jasmine flowers that fall after screening. Guide grooves 11 are provided on the front and back sides of the inner wall of the reserved groove 9. Slider 12 is fixedly connected to the front and back sides of the outer wall of the collection box 10. The two guide grooves 11 are slidably connected to the corresponding sliders 12, which ensures the smoothness and stability of the sliding of the collection box 10. Its function is to facilitate the installation, removal and collection of the collection box 10. A support frame 13 is fixedly connected to the top left side of the screening box 201 to provide support for the dispersing rods 14. Multiple dispersing rods 14 are fixedly connected to the front and back sides of the bottom of the support frame 13 to disperse the jasmine flowers and prevent them from piling up.
[0047] Specifically, the mounting plates 802 at both ends of the reinforcing rod 801 are connected to the vertical plate 701 and the horizontal plate 702 respectively by screws 803 to reinforce the feeding mechanism 7. The reserved groove 9 at the bottom of the screening box 201 cooperates with the slider 12 and guide groove 11 of the collection box 10 to facilitate the collection of the screened material. The dispersing rod 14 of the top left support frame 13 disperses the jasmine flowers during screening to avoid accumulation.
[0048] Working Principle: In actual use, all parts of the entire device work together. First, the jasmine flowers to be screened are poured into the hopper 703 of the feeding mechanism 7. The hopper 703 is supported and fixed on the top left side of the support frame 6 by the vertical plate 701 and the horizontal plate 702. The poured jasmine flowers then fall to the left side of the top screening plate 203. Next, the motor 2081 in the drive assembly 208 is started. The motor 2081 is fixed to the top of the support frame 6, and its output end drives the rotating wheel 2082 to rotate. The rocker arm 2083, which is rotatably connected to the front side of the outer wall of the rotating wheel 2082, moves with the rotation of the rotating wheel 2082, thereby pushing the screening box 201 to sway left and right. During this process, the pulley 2091 in the sliding assembly 209 at the bottom of the screening box 201 slides smoothly in the sliding groove 2092, ensuring that the screening box 201 moves stably left and right. As the screening box 201 sways, multiple... The sieve plate 203 also sways from side to side, causing the jasmine flowers falling on the sieve plate 203 to gradually disperse. They fall into the next layer of sieve plate 203 through the sieve holes 205 on the outer wall of the sieve plate 203 and the soft pad 204. In this process, the soft pad 204 fixedly connected to the top of the sieve plate 203 plays an important role. It has a shock absorption effect on the falling jasmine flowers, effectively preventing the jasmine flowers from being damaged by collision. At the same time, the multiple protrusions 206 on the top of the soft pad 204 increase the contact and friction between the jasmine flowers and the sieve plate 203, so that the jasmine flowers can be more fully turned and screened during the screening. Finally, the jasmine flowers after being screened by multiple layers of sieve plates 203 fall into the guide box 207 fixedly connected to the right side of the outer wall of the sieve plate 203, which is convenient for the staff to collect. This completes the fine screening process of non-green tea tea base jasmine flowers, meeting the needs of fine processing of raw materials before jasmine flower scenting.
[0049] Furthermore, when the tilt angle of the fixing plate 5 needs to be adjusted, the operator rotates the handle 308. Since the inner wall of the handle 308 is threadedly connected to the outer wall of the threaded column 302, and the outer wall of the hollow shell 301 is rotatably connected to the handle 308, the rotation of the handle 308 is converted into axial movement of the threaded column 302. At the same time, the limiting blocks 303 fixedly connected to the left and right sides of the bottom of the outer wall of the threaded column 302 are slidably connected to the limiting grooves 304 opened on the left and right sides of the inner wall of the hollow shell 301. This limiting structure ensures that the threaded column 302 can only move stably in the up and down direction within the hollow shell 301, avoiding deviation or shaking of the threaded column 302 during rotation. As the threaded column 302 moves up and down within the hollow shell 301, because the rotating seat 305 and the threaded column... The top of column 302 is fixedly connected, so the rotating seat 305 will also move up and down synchronously with the threaded column 302. The sliding seat 307 is slidably connected in the sliding groove 306 opened on the front and rear sides of the bottom right end of the screening box 201. The sliding seat 307 is rotatably connected to the rotating seat 305. Therefore, the up and down movement of the rotating seat 305 will drive the sliding seat 307 to slide left and right in the sliding groove 306. The left and right sliding of the sliding seat 307 in the sliding groove 306 causes the right end of the screening box 201 to change height, thereby changing the tilt angle of the fixed plate 5. In this way, the tilt angle of the fixed plate 5 can be flexibly and accurately adjusted according to the characteristics of non-green tea jasmine flowers and the actual screening requirements, optimizing the screening effect and better meeting the needs of fine screening.
