Description

Technical Field

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

[0002] Tea refers to the tender leaves or buds of the tea tree, which are processed into a beverage that can be brewed and drunk. Tea contains rich natural compounds such as tea polyphenols, caffeine, amino acids and minerals, and has the effects of refreshing, relieving heat and promoting health. The tea making process includes picking, withering, killing green, rolling, fermentation, drying and screening. Screening is very important in the tea making process. It can remove impurities, grade, improve the appearance and quality of tea, and improve the brewing effect.

[0003] In the process of screening tea leaves, linear screening equipment can be used. The vibration motor drives the screen to move up and down in a straight line, so that the tea leaves move on the surface of the screen. Then, tea leaves of different particle sizes will be retained in different screen layers respectively, and the vibration of the screen will cause the tea leaves to be discharged from the discharge port, thereby completing the screening of the tea leaves and improving the quality and uniformity of the tea leaves.

[0004] However, the existing linear screening equipment has the following shortcomings:

[0005] 1) In the process of screening tea leaves in the existing screening equipment, tea powder, fragments and impurities tend to adhere to the screen and nozzle components, causing blockage of the screen and nozzle, thereby affecting the normal use of the nozzle and the subsequent cleaning of the screen. In this case, the nozzle needs to be regularly maintained, which increases the workload of the staff. After the screen is cleaned, it needs to be left to dry naturally, which takes a long time and increases the cost of using the screening equipment.

[0006] 2) After the tea leaves are screened, they need to be discharged through a discharge plate. However, the size of the discharge port of the discharge plate is fixed and cannot be adjusted. If a large amount of tea leaves needs to be processed quickly, the width of the discharge port cannot be increased to ensure that enough material passes through. If the screening accuracy of the tea leaves is required to be high, the discharge port cannot be adjusted to maintain a reasonable flow rate. If the discharge port is too small when processing wet tea leaves or tea leaves that are prone to agglomeration, moisture and water cannot be discharged quickly, which can easily form agglomerates or blockages, affecting the normal discharge of tea leaves. This has limitations and reduces the working efficiency of the screening equipment.

[0007] 3) In the prior art, a diffusion sheet is provided at the feed inlet of the screening equipment to break up the tea leaves so that they fall evenly on the screen, thereby preventing the tea leaves from piling up and clogging at the feed inlet. However, when wet or easily agglomerated tea leaves are fed in, if the spacing between the diffusion sheets is too large, the tea leaves are likely to pile up. When drier tea leaves are fed in, if the spacing between the diffusion sheets is too small, the tea leaves are likely to be squeezed or rubbed to the point of being crushed or damaged. The spacing between the diffusion sheets cannot be adjusted according to the characteristics of the tea leaves, which has limitations and is not conducive to the feeding operation of the screening equipment.

[0008] Therefore, we proposed a linear screening equipment for tea processing in order to solve the problems raised above. Summary of the Invention

Then, the inside of the outer shell is quickly dried by the dryer, saving cleaning time. After the cleaning liquid evaporates, it moves back to its original position by the baffle's own gravity, 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 by the above-mentioned background technology.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention achieves a better protection effect through the arrangement of a water tank, a water pump, a water pipe, a high-pressure nozzle, a dryer, a protective box, a water trough, a lifting plate, a baffle, a rack, a gear, a rotating rod and a support block. The cleaning liquid in the water tank is first extracted by the water pump, and then the cleaning liquid is transported to the high-pressure nozzle through the water pipe, so that the high-pressure nozzle sprays the cleaning liquid in the protective box. At this time, the cleaning liquid will accumulate in the water trough and the lifting plate. When the cleaning liquid accumulates to a certain weight, it will drive the lifting plate to descend in the water trough, and then 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 in the slide groove. Move, and then after the baffle moves to the appropriate position, the screen can be rinsed by the high-pressure nozzle. After the screen is rinsed, the inside of the shell is quickly dried by the dryer, saving cleaning time.

Subsequently, the lifting plate and the rack are driven to move by the gravity of the baffle itself, and the baffle moves back to its original position, so that the baffle does not need the aid of a driving device to realize automatic opening and closing. When the baffle is stuck, the baffle can be manually opened and closed by the rotating rod, and the baffle can prevent tea from splashing on the high-pressure nozzle during the screening process to cause clogging, avoiding the problem in the prior art that the nozzle is prone to clogging and the screen needs to be naturally dried after cleaning.

[0022] 2. The present invention is provided with a discharge plate, an adjusting plate, a T-block, a first threaded rod, a turning handle, a fixed rod and a second telescopic rod, which realizes more efficient screening work. The second threaded rod is first driven to rotate by the turning handle, so that the second threaded rod drives the adjusting plate to move, and the adjusting plate drives the T-block to move in the slot, and then the second telescopic rod is driven to extend and retract by the movement of the adjusting plate. Since the movement of the adjusting plate is inclined, the second telescopic rod will rotate on the surface of the fixed rod, and the rotation of the second telescopic rod will adapt to the inclination of the adjusting plate, so that the T-block and the second telescopic rod can limit the moving path of the adjusting plate, thereby increasing the stability of the movement of the adjusting plate, and then the size of the discharge port is adjusted by moving the position of the adjusting plate, thereby improving the working efficiency of the screening equipment and improving the situation that the size of the discharge port of the discharge plate cannot be adjusted in the prior art.

[0023] 3. The present invention is provided with a servo motor, a support rod, a protrusion, a block, a diffuser, a sleeve, a connecting column, a connecting rod, a reset spring, a second threaded rod and a rotating block, which realizes a wider range of applications. The second threaded rod is first driven to rotate by the rotating block, so that the second threaded rod drives the sleeve and the diffuser to move, and the moving path of the sleeve and the diffuser is limited by the protrusion. Then, the diffuser at one end of the support rod drives the connecting column to move, so that the connecting column drives the connecting rod to move therein and the reset spring is compressed, and the diffuser at the other end of the support rod will resist the block, thereby bringing Multiple groups of diffusers move simultaneously. Since each group of diffusers is provided with a return spring to provide reverse elastic force, and the pressure brought by the connecting column and the connecting rod transmission sleeve allows the multiple groups of diffusers to evenly distribute the force they are subjected to, so that the moving distances of the multiple groups of diffusers are the same, and then the spacing between the multiple groups of diffusers is reduced. Conversely, the spacing between the multiple groups of diffusers can be increased through the second threaded rod, so that the screening equipment can adjust the spacing between the diffusers according to the characteristics of the tea, thereby increasing the scope of application of the screening equipment and solving the problem in the prior art that the spacing between the diffusers cannot be adjusted according to the characteristics of the tea.

[0037] The effect achieved by the entire embodiment 1 is: a better protection effect is achieved. The cleaning liquid in the water tank 201 is first extracted by the water pump 202, and then the cleaning liquid is transported to the high-pressure nozzle 204 through the water 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 on the water collection tank 302 and the lifting plate 303.

[0039] The effect achieved by the entire embodiment 2 is: achieving more efficient screening work, first driving the second threaded rod 510 to rotate by the turning handle 405, so that the second threaded rod 510 drives the adjusting plate 402 to move, and drives the T-block 403 to move in the slot through the adjusting plate 402, and then drives the second telescopic rod 407 to extend and retract 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 the rotation of the second telescopic rod 407 will adapt to the inclination of the adjusting plate 402, so that the T-block 403 and the second telescopic rod 407 can limit the moving path of the adjusting plate 402, thereby increasing the stability of the movement of the adjusting plate 402, and then adjusting the size of the discharge port by moving the position of the adjusting plate 402, thereby improving the working efficiency of the screening equipment and facilitating the discharge work of the screening equipment.

[0040] Example 3, according to Figure 3 、 Figure 8 and Figure 9 As shown, the diffusion mechanism 5 includes a servo motor 501, which 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 protrusions 503. One end of the outer surface of the protrusion 503 is fixedly installed with a stopper 504. The outer surface of the protrusion 503 is slidably connected with a sleeve 506 and a plurality of diffusers 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. The diffuser 505 05 is fixedly mounted with a connecting column 507 at one end of the outer surface, and a connecting rod 508 is fixedly mounted with the other end of the outer surface of the diffuser 505, the connecting rod 508 is slidably connected to the inner side of the connecting column 507, and a return spring 509 is fixedly mounted with one end of the outer surface of the connecting rod 508, the other end of the outer surface of the return spring 509 is fixedly mounted on 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, and a rotating block 511 is fixedly mounted with one end of the outer surface of the second threaded rod 510.

[0041] The effect achieved by the entire embodiment 3 is: it achieves a wider range of applications, firstly, the second threaded rod 510 is driven to rotate by the rotating block 511, so that the second threaded rod 510 drives the sleeve 506 and the diffuser 505 to move, and the moving path of the sleeve 506 and the diffuser 505 is limited by the protrusion 503, and then the diffuser 505 at one end of the support rod 502 drives the connecting column 507 to move, so that the connecting column 507 drives the connecting rod 508 to move therein and the return spring 509 is compressed, and the diffuser 505 at the other end of the support rod 502 will resist the block 504. , thereby driving multiple groups of diffusion sheets 505 to move simultaneously. Since each group of diffusion sheets 505 has a return spring 509 to provide reverse elastic force, and the connecting column 507 and the connecting rod 508 transmit the pressure brought by the sleeve 506, the multiple groups of diffusion sheets 505 can evenly distribute the force they are subjected to, so that the moving distances of the multiple groups of diffusion sheets 505 are the same, and then the adjustment of the spacing between the multiple groups of diffusion sheets 505 is completed. Conversely, the spacing between the multiple groups of diffusion sheets 505 can be increased through the second threaded rod 510, so that the screening equipment can adjust the spacing between the diffusion sheets 505 according to the characteristics of the tea, thereby increasing the scope of application of the screening equipment.

[0042] The working principle of the whole equipment is as follows: when using the screening equipment, tea leaves are first put in from the feed port 106, and then the servo motor 501 drives the support rod 502 to rotate, so that the support rod 502 drives the diffusion sheet 505, the sleeve 506 and the threaded rod to rotate, and the bearing supports the sleeve 506 without affecting its rotation, and then the diffusion sheet 505 is used to break up the tea leaves so that the tea leaves fall evenly on the screen 107, and then the vibration motor 105 drives the shell 104 to move up and down linearly, so that the shell 104 drives the screen 107 to move, and the movement of the shell 104 is buffered by the first telescopic rod 102 and the first buffer spring 103, and then the movement of the screen 107 makes The baffle 109 moves inside the storage groove 108, and the movement of the screen 107 and the baffle 109 is buffered by the second buffer spring 110. At the same time, the baffle 109 can also prevent the tea leaves from falling into the storage groove 108. Then, the two sets of screens 107 are used to screen the tea leaves. The larger tea leaves will remain on the upper screen 107, while the smaller tea leaves will fall on the lower screen 107. The tea foam and debris will fall on the bottom of the inner side of the shell 104. Then, the tea leaves are moved to the discharge plate 401 for discharge through the screening and movement of the screen 107. When a large amount of tea leaves need to be processed or the screening accuracy requirements are high, the second threaded rod 510 can be driven to rotate by the turning handle 405, so that the second threaded rod 510 drives the adjusting plate 402 to rotate. The second telescopic rod 407 is extended and retracted by the movement of the adjusting plate 402. Since the movement of the adjusting plate 402 is tilted, the second telescopic rod 407 is rotated on the surface of the fixed rod 406, and the rotation of the second telescopic rod 407 adapts to the tilt of the adjusting plate 402, so that the T-block 403 and the second telescopic rod 407 can limit the moving path of the adjusting plate 402, thereby increasing the stability of the movement of the adjusting plate 402. Then, the size of the discharge port is adjusted by moving the position of the adjusting plate 402, thereby improving the working efficiency of the screening equipment. When the spacing of the diffusion sheet 505 needs to be adjusted to input wet or dry tea leaves, the rotating block 505 can be used to adjust the spacing of the diffusion sheet 505. 11 drives the second threaded rod 510 to rotate, so that the second threaded rod 510 drives the sleeve 506 and the diffuser 505 to move, and limits the movement path of the sleeve 506 and the diffuser 505 through the protrusion 503, and then drives the connecting column 507 to move through the diffuser 505 at one end of the support rod 502, so that the connecting column 507 drives the connecting rod 508 to move therein and the return spring 509 is compressed, and the diffuser 505 at the other end of the support rod 502 will resist the stopper 504, thereby driving multiple groups of diffusers 505 to move at the same time. Since each group of diffusers 505 has a return spring 509 to provide reverse elastic force, and the connecting column 507 and the connecting rod 508 transmit the pressure brought by the sleeve 506,The plurality of diffusers 505 are able to evenly distribute the forces received, so that the moving distances of the plurality of diffusers 505 are the same, and then the spacing between the plurality of diffusers 505 is reduced. Conversely, the spacing between the plurality of diffusers 505 can be increased by the second threaded rod 510, so that the screening device can adjust the spacing between the diffusers 505 according to the characteristics of the tea leaves, thereby increasing the applicable range of the screening device. When the screen 107 needs to be cleaned, the water tank 20 can be pumped out by the water pump 202. 1, and then the cleaning liquid is transported to the high-pressure nozzle 204 through the water 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 on the water collection 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 collection tank 302, and then the movement of the lifting plate 303 will drive the rack 305 to move in the moving groove, and then the rack 305 will drive the gear 306 to rotate. The gear 306 drives the rotating rod 307 to rotate, and drives the baffle 304 to move in the chute through the rack 305. 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 housing 104 and the screen 107 are quickly dried by the dryer 205. At this time, the cleaning liquid in the protective box 301 will evaporate, and the baffle 304 will lose the cleaning liquid on the lifting plate 303. The added gravity then drives the lifting plate 303 and the rack 305 to move through the baffle 304's own gravity, and the baffle 304 moves back to its original position, allowing the baffle 304 to open and close automatically without the need for a drive device. When the baffle 304 gets stuck, the gear 306 and the rack 305 can be driven by the rotating rod 307 to move, and the positions of the lifting plate 303 and the baffle 304 can be manually adjusted. The baffle 304 can prevent tea leaves from splashing onto the high-pressure nozzle 204 during the screening process, causing it to become clogged.
