Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and particularly to a linear screening device for tea processing. Background Art

[0002] Tea refers to the young leaves or buds of tea plants, which are processed into drinkable raw materials after processing. Tea contains rich natural compounds such as tea polyphenols, caffeine, amino acids and minerals, and has effects such as refreshing, relieving summer heat and promoting health. The production process of tea includes steps such as picking, withering, fixation, rolling, fermentation, drying and screening. Screening is very important in the production process of tea. It can remove impurities, classify, improve the appearance and quality of tea, and improve the brewing effect.

[0003] During the process of screening tea, a linear screening device can be used. The vibrating motor drives the screen to move linearly up and down, so that the tea moves on the surface of the screen. Then, tea of different particle sizes will remain on different screen layers respectively, and the tea is discharged from the discharge port through the vibration of the screen, thus completing the screening work of tea and improving the quality and uniformity of tea.

[0004] However, the existing linear screening devices have the following deficiencies: 1) In the prior art, during the process of screening tea, the powder, fragments and impurities of tea are easily adhered to components such as the screen and the nozzle, causing blockage of the screen and the nozzle, thus affecting the normal use of the nozzle and the subsequent cleaning work of the screen. At this time, the nozzle needs to be maintained regularly, increasing the workload of the staff, and after the screen is cleaned, it needs to wait for natural air drying, which takes a long time and increases the use cost of the screening device; 2) After the tea screening is completed, it needs to be discharged through the discharge plate. The size of the discharge port of the discharge plate is fixed and cannot be adjusted. If a large amount of tea needs to be processed quickly, the width of the discharge port cannot be increased to ensure that enough materials can pass through; if a high screening accuracy is required for the tea, the discharge port cannot be adjusted to maintain a reasonable flow rate; if wet tea or easily caking tea is processed, too small a discharge port will cause moisture and water to be unable to be discharged quickly, easily forming lumps or blockages, affecting the normal discharge of tea, having limitations and reducing the working efficiency of the screening device; 3) In the prior art, a diffusion plate is arranged at the feed inlet of the screening device to disperse the tea, so that the tea evenly falls on the screen to prevent the tea from accumulating and blocking at the feed inlet. However, when wet or easily caking tea is put in, if the spacing of the diffusion plate is too large, the tea is likely to accumulate; when relatively dry tea is put in, if the spacing of the diffusion plate is too small, the tea is likely to be crushed or damaged due to greater extrusion or friction, and the spacing of the diffusion plate cannot be adjusted according to the characteristics of the tea, having limitations and being not conducive to the feeding work of the screening device.

[0005] Therefore, we propose a linear screening device for tea processing to facilitate the solution of the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a linear screening device for tea processing to achieve a more excellent protection effect. First, the cleaning liquid is sprayed into the protection box by a high-pressure nozzle, so that the cleaning liquid accumulates in the water collecting tank and the lifting plate. Then, the gravity exerted by the cleaning liquid on the lifting plate drives the rack, gear and rotating rod to move, so that the rack drives the baffle to move to a suitable position, and then the high-pressure nozzle is used to wash the screen mesh. Then, the inner side of the housing is quickly dried by a dryer, saving the cleaning time. After the cleaning liquid evaporates, it moves back to its original position by the gravity of the baffle itself, so that the baffle can be automatically opened and closed without the aid of a driving device, and the baffle prevents tea leaves from splashing on the high-pressure nozzle and causing blockage, so as to solve the problems raised in the above background technology.

[0013] Preferably, a first threaded rod is fixedly installed on one side of the outer surface of the adjusting plate. The first threaded rod is rotatably connected to one side of the outer surface of the discharging plate, and a turning handle is fixedly installed at one end of the outer surface of the first threaded rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the settings of a water tank, a water pump, a water delivery pipe, a high-pressure nozzle, a dryer, a protective box, a water collecting tank, a lifting plate, a baffle plate, a rack, a gear, a rotating rod and a support block, the present invention achieves a better protection effect. First, the cleaning liquid in the water tank is pumped by the water pump, and then the cleaning liquid is conveyed to the high-pressure nozzle through the water delivery pipe, so that the high-pressure nozzle sprays the cleaning liquid into the protective box. At this time, the cleaning liquid will accumulate in the water collecting tank and on the lifting plate. When the cleaning liquid accumulates to a certain weight, it will drive the lifting plate to descend in the water collecting tank. Subsequently, the movement of the lifting plate drives the rack to move in the moving groove, and then the rack drives the gear to rotate, so that the gear drives the rotating rod to rotate, and the rack drives the baffle plate to move in the sliding groove. Then, after the baffle plate moves to a suitable position, the sieve mesh can be rinsed by the high-pressure nozzle. After the sieve mesh is rinsed, the inner side of the shell is quickly dried by the dryer, saving the cleaning time. At this time, the cleaning liquid in the protective box will evaporate, and the baffle plate will lose the gravity exerted by the cleaning liquid on the lifting plate. Subsequently, the baffle plate drives the lifting plate and the rack to move by its own gravity, and the baffle plate moves back to its original position, enabling the baffle plate to automatically open and close without the aid of a driving device. When the baffle plate gets stuck, the baffle plate can be manually opened and closed through the rotating rod, and the baffle plate can prevent tea leaves from splashing on the high-pressure nozzle during the screening process and causing blockage, avoiding the problems that the nozzle in the prior art is prone to blockage and the sieve mesh needs to be naturally air-dried after cleaning.

[0017] 2. The present invention is provided with a discharge plate, an adjusting plate, a T-shaped block, a first threaded rod, a rotating handle, a fixing rod and a second telescopic rod, achieving more efficient screening work. First, the rotating handle drives the second threaded rod to rotate, so that the second threaded rod drives the adjusting plate to move, and the adjusting plate drives the T-shaped block to move in the card slot. Then, the movement of the adjusting plate drives the second telescopic rod to expand and contract. Since the movement of the adjusting plate is inclined, the second telescopic rod will rotate on the surface of the fixing rod, and the rotation of the second telescopic rod is used to adapt to the inclination of the adjusting plate, enabling the T-shaped block and the second telescopic rod to limit the movement path of the adjusting plate, increasing the stability of the movement of the adjusting plate. Then, by moving the position of the adjusting plate, the size of the discharge port is adjusted, improving the working efficiency of the screening equipment and improving the situation in the prior art where the size of the discharge port of the discharge plate cannot be adjusted.

[0018] 3. The present invention is provided with a servo motor, a support rod, a bump, a stop block, a diffusion plate, a sleeve, a connecting column, a connecting rod, a return spring, a second threaded rod and a rotating block, achieving a wider range of applications. First, the rotating block drives the second threaded rod to rotate, causing the second threaded rod to drive the sleeve and the diffusion plate to move, and the movement path of the sleeve and the diffusion plate is limited by the bump. Subsequently, the diffusion plate at one end of the support rod drives the connecting column to move, enabling the connecting column to drive the connecting rod to move within it and compress the return spring. Moreover, the diffusion plate at the other end of the support rod will abut against the stop block, thereby driving multiple groups of diffusion plates to move simultaneously. Since a return spring provides a reverse elastic force at each group of diffusion plates, and the connecting column and the connecting rod transmit the pressure brought by the sleeve, multiple groups of diffusion plates can evenly distribute the force they receive, so that the movement distances of multiple groups of diffusion plates are the same. Then, the work of reducing the spacing between multiple groups of diffusion plates is completed. Conversely, the spacing between multiple groups of diffusion plates can be increased by the second threaded rod, enabling the screening device to adjust the spacing of the diffusion plates according to the characteristics of the tea leaves, increasing the applicable range of the screening device, and solving the problem in the prior art that the spacing of the diffusion plates cannot be adjusted according to the characteristics of the tea leaves.

[0022] Please refer to the attached Figure 1 - attached Figure 9 As shown, the present invention provides a technical solution: a linear screening device for tea processing, including a machine body 1. The machine body 1 includes a support frame 101. The top of the support frame 101 is fixedly installed with a first telescopic rod 102 and a first buffer spring 103. The tops of the first telescopic rod 102 and the first buffer spring 103 are both fixedly installed with an outer shell 104. The surface of the outer shell 104 is provided with a cleaning mechanism 2, a protection mechanism 3 and a discharging mechanism 4, and a diffusion mechanism 5 is installed inside the outer shell 104.

[0023] Example 1, according to Figures 1-5As shown, a vibration motor 105 and a screen 107 are respectively installed at the bottom end and the inner side of the outer shell 104, and a feed inlet 106 and a storage groove 108 are respectively provided at the top end and both sides of the outer surface of the outer shell 104. A baffle 109 is slidably connected to the inner side of the storage groove 108. The cleaning mechanism 2 includes a water tank 201. The water tank 201 is arranged on one side of the outer surface of the support frame 101, and a water pump 202 is installed at the top end of the water tank 201. The output end of the water pump 202 is installed with a water delivery pipe 203, and the output end of the water delivery pipe 203 is installed with a high-pressure nozzle 204. The high-pressure nozzle 204 is arranged on one side of the inner surface of the outer shell 104. A dryer 205 is installed on the other side of the inner surface of the outer shell 104. The baffle 109 is fixedly installed on both sides of the outer surface of the screen 107, and a second buffer spring 110 is fixedly installed on one side of the outer surface of the baffle 109. The protection mechanism 3 includes a protection box 301. The protection box 301 is fixedly installed on one side of the inner surface of the outer shell 104, and a water collecting groove 302 is provided on the inner surface of the protection box 301. A lifting plate 303 is slidably connected to the inner side of the water collecting groove 302. A chute is provided inside the protection box 301, and a baffle 304 is slidably connected to the inner side of the chute. A moving groove is provided at the top end of the protection box 301, and a rack 305 is slidably connected to the inner side of the moving groove. The rack 305 is fixedly installed at the top ends of the baffle 304 and the lifting plate 303. A gear 306 is rotatably connected to the inner side of the rack 305. A rotating rod 307 is fixedly installed on the outer surface of the gear 306. A support block 308 is fixedly installed at the top end of the protection box 301. The rotating rod 307 is rotatably connected to the outer surface of the support block 308.

[0024] The effects achieved by the entire Embodiment 1 are as follows: It realizes a more excellent protection effect. First, the cleaning liquid in the water tank 201 is pumped out by the water pump 202, and then the cleaning liquid is conveyed to the high-pressure nozzle 204 through the water delivery pipe 203, so that the high-pressure nozzle 204 sprays the cleaning liquid into the protection box 301. At this time, the cleaning liquid will accumulate in the water collecting tank 302 and the lifting plate 303. When the cleaning liquid accumulates to a certain weight, it will drive the lifting plate 303 to descend in the water collecting tank 302. Subsequently, the movement of the lifting plate 303 drives the rack 305 to move in the moving groove, and then the rack 305 drives the gear 306 to rotate, so that the gear 306 drives the rotating rod 307 to rotate, and the rack 305 drives the baffle plate 304 to move in the sliding groove. Then, after the baffle plate 304 moves to a suitable position, the sieve mesh 107 can be rinsed by the high-pressure nozzle 204. After the sieve mesh 107 is rinsed, the inner side of the outer shell 104 is quickly dried by the dryer 205, saving the cleaning time. At this time, the cleaning liquid in the protection box 301 will evaporate, and the baffle plate 304 will lose the gravity exerted by the cleaning liquid on the lifting plate 303. Subsequently, the baffle plate 304 drives the lifting plate 303 and the rack 305 to move by its own gravity, and the baffle plate 304 moves back to its original position, enabling the baffle plate 304 to automatically open and close without the aid of a driving device. When the baffle plate 304 gets stuck, the baffle plate 304 can be manually opened and closed through the rotating rod 307, and the baffle plate 304 can prevent tea leaves from splashing on the high-pressure nozzle 204 during the screening process and causing blockage to it, improving the protection effect on the high-pressure nozzle 204.

[0025] Embodiment 2, according to Figure 3 、 Figure 6 and Figure 7 As shown, the discharging mechanism 4 includes a discharging plate 401. Multiple groups of discharging plates 401 are cross-distributed at the bottom ends of the sieve mesh 107 and the outer shell 104, and an adjusting plate 402 is slidably connected to the outer surface of the discharging plate 401. Card slots are provided at the top end of the adjusting plate 402 and the bottom end of the discharging plate 401, and T-shaped blocks 403 are fixedly installed on the inner surfaces of the adjusting plate 402 and the discharging plate 401. The T-shaped blocks 403 are slidably connected to the inner sides of the card slots. A first threaded rod 404 is fixedly installed on one side of the outer surface of the adjusting plate 402. The first threaded rod 404 is rotatably connected to one side of the outer surface of the discharging plate 401, and a turning handle 405 is fixedly installed at one end of the outer surface of the first threaded rod 404. A fixing rod 406 is fixedly installed on the inner surface of the adjusting plate 402. A second telescopic rod 407 is rotatably connected to the outer surface of the fixing rod 406, and the other end of the outer surface of the second telescopic rod 407 is fixedly installed at the top end of the discharging plate 401.

[0026] The effect achieved by the entire Embodiment 2 is as follows: more efficient screening work is realized. First, the rotary handle 405 drives the second threaded rod 510 to rotate, causing the second threaded rod 510 to drive the adjusting plate 402 to move. The adjusting plate 402 drives the T-shaped block 403 to move in the card slot. Then, the movement of the adjusting plate 402 drives the second telescopic rod 407 to expand and contract. Since the movement of the adjusting plate 402 is inclined, the second telescopic rod 407 rotates on the surface of the fixed rod 406, and the rotation of the second telescopic rod 407 adapts to the inclination of the adjusting plate 402, enabling the T-shaped block 403 and the second telescopic rod 407 to limit the movement path of the adjusting plate 402, increasing the stability of the movement of the adjusting plate 402. Then, by moving the position of the adjusting plate 402, the size of the discharge port is adjusted, improving the working efficiency of the screening device and facilitating the discharging work of the screening device.

[0027] Embodiment 3, according to Figure 3 、 Figure 8 and Figure 9 As shown, the diffusion mechanism 5 includes a servo motor 501. The servo motor 501 is installed on one side of the outer surface of the housing 104. A support rod 502 is installed at the output end of the servo motor 501. Both sides of the outer surface of the support rod 502 are fixedly installed with convex blocks 503. One end of the outer surface of the convex block 503 is fixedly installed with a stop block 504. The outer surface of the convex block 503 is slidably connected with a sleeve 506 and a plurality of diffusion sheets 505. A bearing is fixedly installed on the inner surface of the housing 104. The sleeve 506 is rotatably connected to the inner side of the bearing. One end of the outer surface of the diffusion sheet 505 is fixedly installed with a connecting column 507. The other end of the outer surface of the diffusion sheet 505 is fixedly installed with a connecting rod 508. The connecting rod 508 is slidably connected to the inner side of the connecting column 507. One end of the outer surface of the connecting rod 508 is fixedly installed with a return spring 509. The other end of the outer surface of the return spring 509 is fixedly installed at one end of the inner surface of the connecting column 507. The inner surface of the sleeve 506 is rotatably connected with a second threaded rod 510. One end of the outer surface of the second threaded rod 510 is fixedly installed with a rotating block 511.

[0028] The effect achieved by the entire Embodiment 3 is as follows: a wider applicable range is realized. First, the rotating block 511 drives the second threaded rod 510 to rotate, causing the second threaded rod 510 to drive the sleeve 506 and the diffusion plate 505 to move. The bump 503 limits the movement path of the sleeve 506 and the diffusion plate 505. Subsequently, the diffusion plate 505 at one end of the support rod 502 drives the connecting column 507 to move, causing the connecting column 507 to drive the connecting rod 508 to move therein and compress the return spring 509. Moreover, the diffusion plate 505 at the other end of the support rod 502 will abut against the stop block 504, thereby driving multiple diffusion plates 505 to move simultaneously. Since a return spring 509 provides a reverse elastic force at each group of diffusion plates 505, and the connecting column 507 and the connecting rod 508 transmit the pressure brought by the sleeve 506, the multiple diffusion plates 505 can evenly distribute the force received, so that the movement distances of the multiple diffusion plates 505 are the same. Then, the adjustment of reducing the distance between multiple diffusion plates 505 is completed. On the contrary, the distance between multiple diffusion plates 505 can be increased by the second threaded rod 510, enabling the screening device to adjust the distance between the diffusion plates 505 according to the characteristics of the tea, and increasing the applicable range of the screening device.

[0029] The working principle of the entire device is as follows: During the use of the screening device, first put the tea leaves into the feeding port 106, and then drive the support rod 502 to rotate through the servo motor 501, so that the support rod 502 drives the diffusion sheet 505, the sleeve 506 and the threaded rod to rotate, and support the sleeve 506 through the bearing without affecting its rotation. Then, the put-in tea leaves are scattered by the diffusion sheet 505, so that the tea leaves evenly fall on the sieve mesh 107. Subsequently, drive the outer shell 104 to perform a linear up-and-down movement through the vibration motor 105, so that the outer shell 104 drives the sieve mesh 107 to move, and buffer the movement of the outer shell 104 through the first telescopic rod 102 and the first buffer spring 103. Then, through the movement of the sieve mesh 107, the baffle 109 moves inside the receiving groove 108, and buffer the movement of the sieve mesh 107 and the baffle 109 through the second buffer spring 110. At the same time, the baffle 109 can also block the tea leaves from falling into the receiving groove 108. Then, screen the tea leaves through the two groups of sieve meshes 107. The larger tea leaves will remain on the upper sieve mesh 107, while the smaller tea leaves will fall on the lower sieve mesh 107, and the tea foam and debris will fall on the bottom inside the outer shell 104. Subsequently, drive the tea leaves to move to the discharge plate 401 for discharge through the screening and movement of the sieve mesh 107. When a large amount of tea leaves need to be processed or the tea leaves with high screening accuracy requirements are processed, the second threaded rod 510 can be driven to rotate through the turning handle 405, so that the second threaded rod 510 drives the adjusting plate 402 to move, and drives the T-shaped block 403 to move in the card slot through the adjusting plate 402. Then, drive the second telescopic rod 407 to stretch and contract through the movement of the adjusting plate 402. Since the movement of the adjusting plate 402 is inclined, the second telescopic rod 407 will rotate on the surface of the fixed rod 406, and adapt to the inclination of the adjusting plate 402 through the rotation of the second telescopic rod 407, so that the T-shaped block 403 and the second telescopic rod 407 realize the limit of the movement path of the adjusting plate 402, increasing the stability of the movement of the adjusting plate 402. Then, adjust the size of the discharge port by moving the position of the adjusting plate 402, improving the working efficiency of the screening device. When it is necessary to adjust the spacing of the diffusion sheets 505 to put in wet or dry tea leaves, the second threaded rod 510 can be driven to rotate through the rotating block 511, so that the second threaded rod 510 drives the sleeve 506 and the diffusion sheet 505 to move, and limit the movement path of the sleeve 506 and the diffusion sheet 505 through the convex block 503. Subsequently, drive the connecting column 507 to move through the diffusion sheet 505 at one end of the support rod 502, so that the connecting column 507 drives the connecting rod 508 to move inside it and compress the return spring 509, and the diffusion sheet 505 at the other end of the support rod 502 will abut against the stop block 504, thereby driving multiple groups of diffusion sheets 505 to move simultaneously. Since a reverse elastic force is provided by the return spring 509 at each group of diffusion sheets 505, and the connecting column 507 and the connecting rod 508 transmit the pressure brought by the sleeve 506,The force received by multiple groups of diffusion sheets 505 is evenly distributed, so that the moving distances of multiple groups of diffusion sheets 505 are the same, and then the work of reducing the spacing between multiple groups of diffusion sheets 505 is completed. On the contrary, the spacing between multiple groups of diffusion sheets 505 can be increased by the second threaded rod 510, so that the screening device can adjust the spacing of the diffusion sheets 505 according to the characteristics of the tea leaves, increasing the applicable range of the screening device. When it is necessary to clean the screen 107, the cleaning liquid in the water tank 201 can be pumped by the water pump 202, and then the cleaning liquid is transported to the high-pressure nozzle 204 through the water delivery pipe 203, so that the high-pressure nozzle 204 sprays the cleaning liquid into the protective box 301. At this time, the cleaning liquid will accumulate in the water collecting tank 302 and the lifting plate 303. When the cleaning liquid accumulates to a certain weight, it will drive the lifting plate 303 to descend in the water collecting tank 302. Subsequently, the movement of the lifting plate 303 drives the rack 305 to move in the moving groove, and then the rack 305 drives the gear 306 to rotate, so that the gear 306 drives the rotating rod 307 to rotate, and the rack 305 drives the baffle 304 to move in the sliding groove. Then, after the baffle 304 moves to a suitable position, the screen 107 can be rinsed by the high-pressure nozzle 204. After the screen 107 is rinsed, the dryer 205 quickly dries the inside of the housing 104 and the screen 107. At this time, the cleaning liquid in the protective box 301 will evaporate, and the baffle 304 will lose the gravity exerted by the cleaning liquid on the lifting plate 303. Subsequently, the gravity of the baffle 304 itself drives the lifting plate 303 and the rack 305 to move, and the baffle 304 moves back to its original position, enabling the baffle 304 to automatically open and close without the aid of a driving device. When the baffle 304 gets stuck, the rotating rod 307 can be used to drive the gear 306 and the rack 305 to move, manually adjusting the positions of the lifting plate 303 and the baffle 304, and the baffle 304 can prevent tea leaves from splashing on the high-pressure nozzle 204 during the screening process and causing blockage to it.
