Description

Technical Field

[0001] The invention belongs to the technical field of tea processing, in particular to a device for detecting moisture in floral white tea. Background Art

[0002] Floral white tea is a kind of white tea with a unique floral scent. Its fragrance is fragrant and elegant, and is deeply loved by tea lovers. Tea withering moisture detection refers to judging the dryness and quality of tea by measuring the moisture content in the tea after withering. Withering is an important link in the tea processing process. After withering, the reduction of moisture content in the tea has an important impact on the taste, aroma and color of the tea.

[0003] A Chinese patent with announcement number CN113899712B discloses a tea withering moisture detection device and detection method. In this technical solution, the orifice plate is in a horizontal position, and the tea to be detected is placed on the orifice plate, and then the orifice plate is driven to move up by a set lifting component. When the orifice plate moves up, the supporting effect of the receiving platform is lost, so that the tea moves on the orifice plate when the orifice plate rotates downward, and with the action of the negative pressure component, a tea leaf is adsorbed on a through hole on the orifice plate. When the orifice plate abuts against the rotating drive member, the orifice plate continues to move up, so that the orifice plate rotates in the opposite direction to achieve a second spreading of the tea leaves, and the excess tea leaves fall out. Then the orifice plate is reset, and the detection mechanism is set to perform chromatographic collection on the tea leaves on the orifice plate to realize the detection of tea withering moisture, prevent the problem of multiple tea leaves stacked to affect the detection effect, effectively improve the accuracy of the detection, and have strong practicality.

[0004] However, in the above technical solution, when performing the detection work, the tea leaves need to be placed on the orifice plate first, and then the excess tea leaves need to be poured out after the tea leaves are adsorbed by the orifice plate. Only after the excess tea leaves are poured out can the detection be carried out. After the detection is completed, the tea leaves need to be placed on the orifice plate again to repeat the operation. This method is cumbersome to operate and the tea leaf detection efficiency is low.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 10As shown, a moisture detection device for floral white tea described in an embodiment of the present invention comprises a base 1, a hopper 2 is fixedly installed on the top of the base 1, adsorption rollers 3 are symmetrically arranged on the inner side of the hopper 2, adsorption holes 4 are evenly opened on the outer surface of the adsorption rollers 3, a rotating joint 5 is fixedly installed on the side where the two adsorption rollers 3 are close to each other, a connecting pipe 6 is fixedly installed between the two rotating joints 5, the connecting pipe 6 is connected with the adsorption rollers 3 through the rotating joint 5, a positioning frame 7 is rotatably installed on the outer wall of the side where the two adsorption rollers 3 are close to each other, a connecting plate 8 is fixedly installed between the two positioning frames 7, a mounting seat 9 is fixedly installed on the outer walls of the two positioning frames 7 and the connecting plate 8, a negative pressure machine 10 is fixedly installed inside the mounting seat 9, a connecting pipe 11 is fixedly installed inside the negative pressure machine 10, an end of the connecting pipe 11 away from the negative pressure machine 10 passes through the connecting plate 8 and is connected with the connecting pipe 6, the top of the hopper 2 A receiving block 21 is provided on the side, and a detection seat 26 is symmetrically fixedly installed on the outer wall of the receiving block 21, and a spectrum collection board 27 is fixedly installed on the inner wall of the detection seat 26; when working, the floral white tea is placed inside the hopper 2, and the height of the floral white tea is lower than the height of the partition 16. The negative pressure machine 10 is connected with the adsorption roller 3 through the connecting pipe 11, the connecting pipe 6 and the rotating joint 5. After starting the negative pressure machine 10, the negative pressure machine 10 generates negative pressure inside the adsorption roller 3 through the connecting pipe 11, the connecting pipe 6 and the rotating joint 5. The adsorption roller 3 uses the internal negative pressure to adsorb the white tea inside the hopper 2 on the surface of the adsorption roller 3 through the adsorption hole 4, thereby achieving the effect of fixing the floral white tea to be detected. After the adsorption roller 3 adsorbs the floral white tea, it moves the floral white tea to one side of the spectrum collection board 27, and performs chromatographic collection on the floral white tea through the spectrum collection board 27, thereby performing moisture detection on the floral white tea.

[0040] like Figures 1 to 8As shown, a support frame 12 is symmetrically fixedly installed on the top of the hopper 2, a driving motor 13 is fixedly installed on the outer wall of one of the support frames 12, a driving shaft 14 is rotatably installed between the inner walls of the two support frames 12, the output end of the driving motor 13 is fixedly connected to one end of the driving shaft 14, a rotating seat 15 is fixedly installed on the outer wall of the driving shaft 14, a partition 16 is fixedly installed on the inner wall of the hopper 2, a plurality of teeth A17 are evenly fixedly installed on the outer wall of the rotary joint 5, and a plurality of teeth B18 matched with the teeth A17 are evenly fixedly installed on the outer wall of the partition 16; when the driving motor 13 is started, the driving motor 13 drives the driving shaft 14 to rotate, the rotating seat 15 is connected to the mounting seat 9 through the automatic telescopic rod 45, and the driving shaft 14 During rotation, the adsorption roller 3 is driven to move by structures such as the rotating seat 15, the automatic telescopic rod 45 and the mounting seat 9. When the adsorption roller 3 passes through the tooth B18 during movement, the tooth B18 will mesh with the tooth A17. When the adsorption roller 3 moves while the tooth B18 and the tooth A17 are in meshing state, since the part of the rotary joint 5 where the tooth A17 is installed is fixed to the adsorption roller 3, the rotary joint 5 will drive the adsorption roller 3 to rotate. At the same time, since the rotary joint 5 itself has the characteristic of being able to rotate while ensuring the sealing, it provides conditions for the rotation of the adsorption roller 3. Therefore, the adsorption roller 3 will rotate on its own. Through the self-rotation of the adsorption roller 3, the circumferential surface of the adsorption roller 3 is adsorbed on the floral white tea to be detected, thereby improving the subsequent detection efficiency.

[0041] like Figures 1 to 10 As shown, an arc plate 19 is arranged above the hopper 2, a fixed block 20 is fixedly installed on one end of the arc plate 19, an arc telescopic shaft 22 is fixedly installed on the outer wall of the fixed block 20, one end of the arc telescopic shaft 22 is fixedly connected to the outer wall of the receiving block 21, a support A23 is fixedly installed on the outer wall of the arc telescopic shaft 22 close to the fixed block 20, a support B24 is fixedly installed on the outer wall of the arc telescopic shaft 22 close to the receiving block 21, the outer wall of the support A23 is fixedly connected to the outer wall of the arc plate 19, an arc elastic member 25 is fixedly installed between the support B24 and the outer wall of the support A23 and on the outside of the arc telescopic shaft 22, and a tooth plate A28 is fixedly installed on the end of the arc plate 19 away from the fixed block 20. A top block 56 is fixedly installed on the outer wall of the mounting seat 9; when the adsorption roller 3 moves with the floral white tea to be detected, the top block 56 will abut against the receiving block 21 and push the receiving block 21 to move. When the top block 56 contacts the receiving block 21, the spectrum collection plate 27 is located on the outside of the adsorption roller 3. As the top block 56 squeezes the receiving block 21, the arc-shaped telescopic shaft 22 and the arc-shaped elastic member 25 will shrink. When the arc-shaped telescopic shaft 22 shrinks, the tooth A17 will mesh with the tooth plate A28. Under the action of the tooth plate A28, the adsorption roller 3 will rotate. While the adsorption roller 3 rotates, the spectrum collection plate 27 will detect the floral white tea on the surface of the adsorption roller 3, thereby achieving the effect of detecting the moisture content of the floral white tea.

[0042] like Figures 1 to 11 As shown, a placement seat 29 is fixedly installed on one side of the base 1, a support plate 30 is fixedly installed on the top of the placement seat 29, a tooth plate B31 is fixedly installed on the top of the support plate 30, and an automatic telescopic rod 45 is fixedly installed between the mounting seat 9 and the rotating seat 15; when the spectrum collection board 27 completes the detection of the floral white tea, the driving motor 13 will drive the adsorption roller 3 to reverse, and when the automatic telescopic rod 45 is parallel to the tooth plate B31, the driving motor 13 stops rotating, and at this time the automatic telescopic rod 45 extends to push the adsorption roller 3 to move in a straight line toward the direction of the tooth plate B31, and the direction in which the adsorption roller 3 moves is parallel to the tooth plate B31, and the tooth A17 will contact and mesh with the tooth plate B31. At this time, the adsorption roller 3 is located above the collection box 49 inside the placement seat 29, and when the tooth A17 meshes with the tooth plate B31, the negative pressure machine 10 will automatically close and stop the adsorption work, and the white tea attached to the adsorption roller 3 will fall off. Under the movement of the adsorption roller 3, due to the meshing of the tooth A17 and the tooth plate B31, the adsorption roller 3 will rotate, so that the white tea above the adsorption roller 3 can also fall off, and the fallen white tea falls into the collecting box 49, thereby achieving the effect of automatic unloading. When the white tea is finished unloading, the automatic telescopic rod 45 begins to shrink. After the shrinkage is completed, the adsorption roller 3 continues to reverse. When the automatic telescopic rod 45 completes the shrinkage, under the action of the driving motor 13, the adsorption roller 3 whose surface no longer adsorbs the floral white tea continues to reverse to the inner side of the hopper 2 to achieve reset. After the adsorption roller 3 returns to the inner side of the hopper 2, it will adsorb the floral white tea inside the hopper 2 again, so as to carry out the next step of the floral white tea detection process, thereby achieving the effect of continuous detection.

[0043] like Figures 1 to 13As shown, a positioning plate 32 is symmetrically fixedly installed on the top of the hopper 2, and an air guide plate 33 is fixedly installed on the outer wall of the positioning plate 32. The adsorption roller 3 is located below the air guide plate 33. An air guide duct 34 is fixedly installed on the inner wall of the two air guide plates 33 away from each other. A fan 35 is fixedly installed on the bottom of the base 1. One end of the two air guide ducts 34 away from the air guide plate 33 is fixedly connected to the inner wall of the fan 35. Air jet holes 36 are evenly opened at the bottom of the air guide plate 33, and a plurality of teeth C37 adapted to the teeth A17 are evenly fixedly installed on the outer wall of the partition 16. When the adsorption roller 3 adsorbs the floral white tea, it will move to the bottom of the air guide plate 33, and the fan 35 During operation, external air is drawn in to generate air flow, which enters the interior of the air duct 34 through the fan 35. The air flow entering the air duct 34 will follow the air duct 34 into the interior of the air guide plate 33. After entering the air guide plate 33, the air flow will be ejected through the air jet hole 36. When the adsorption roller 3 moves to the bottom of the air guide plate 33, the tooth A17 will mesh with the tooth C37. Under the action of the tooth C37, the adsorption roller 3 will rotate. After being ejected through the air jet hole 36, the air flow will blow toward the rotating adsorption roller 3. The floral white tea on the adsorption roller 3 away from the adsorption hole 4 will be blown away by the air flow, thereby reducing the amount of white tea overlapping on the surface of the adsorption roller 3 and improving the detection effect of the device.

[0044] like Figures 1 to 14 As shown, the inner wall of the hopper 2 is symmetrically provided with arc-shaped chutes 38, the inner walls of the two arc-shaped chutes 38 are slidably mounted with sliders 39, a material-dispensing plate 40 is fixedly mounted between the outer walls of the two sliders 39, the material-dispensing plate 40 is located on one side of the adsorption roller 3, a mounting box A41 is fixedly mounted on the outer wall of the material-dispensing plate 40, a magnet A42 is fixedly mounted on the inner wall of the mounting box A41, a mounting box B43 is fixedly mounted between the outer walls of the two positioning frames 7, a magnet B44 is fixedly mounted on the inner wall of the mounting box B43, and the magnet B44 and the magnet A42 are magnetically attracted to each other; when the adsorption roller 3 moves toward the direction of the material-dispensing plate 40, the material-dispensing plate 40 is fixedly mounted 0 will move under the action of thrust. When the sliders 39 on both sides of the material-discharging plate 40 move to the end positions of the arc-shaped chute 38, the adsorption roller 3 starts to move to the side away from the material-discharging plate 40. When moving, due to the magnetic attraction between the magnet A 42 and the magnet B 44, the material-discharging plate 40 will be pulled to move when the adsorption roller 3 moves. When the slider 39 moves to the end position at the other end of the arc-shaped chute 38, the magnet A 42 and the magnet B 44 are separated by the restriction of the arc-shaped chute 38. The floral white tea inside the hopper 2 can be evenly spread through the movement of the material-discharging plate 40, so that the adsorption roller 3 can effectively adsorb the white tea.

[0045] like Figures 1 to 9As shown, the outer wall of the hopper 2 is symmetrically fixed with side plates 46, a top plate 47 is fixedly installed between the outer walls of the two side plates 46, a receiving plate 48 is fixedly installed on the outer wall of the top plate 47, and the arc plate 19 and the tooth plate A28 are fixedly connected to the receiving plate 48; the top plate 47 is fixed by the side plates 46 so that the top plate 47 is located above the base 1, and the arc plate 19 and the tooth plate A28 are fixed to the top plate 47 by the receiving plate 48, and the positions of the arc plate 19 and the tooth plate A28 are determined to ensure the normal operation of the device.

[0046] like Figures 1 to 11 As shown, the inner wall of the placement seat 29 is symmetrically provided with a collecting box 49, and the top of the collecting box 49 is symmetrically fixed with a handle 50; when the automatic telescopic rod 45 is extended, the adsorption roller 3 will pass through between the two side plates 46 and move to the top of the collecting box 49. When the negative pressure machine 10 stops working, the floral white tea on the surface of the adsorption roller 3 will fall into the interior of the collecting box 49, and the floral white tea will be collected by the collecting box 49. The collecting box 49 can be conveniently lifted by the handle 50, thereby facilitating the processing of the floral white tea inside.

[0047] like Figures 1 to 4 As shown, the outer wall of the driving shaft 14 is symmetrically fixed with reinforcing arms 51, a reinforcing rod 52 is fixedly installed between the inner walls of the two reinforcing arms 51, the outer wall of the reinforcing rod 52 is fixedly connected to the inner wall of the rotating seat 15, and the outer wall of the mounting seat 9 is symmetrically fixed with sliding rods 53, the outer wall of the sliding rod 53 is slidably connected to the inner wall of the rotating seat 15; through the cooperation of the reinforcing arms 51 and the reinforcing rods 52, the connection strength between the driving shaft 14 and the rotating seat 15 is increased, so that the driving shaft 14 can stably drive the rotating seat 15 to rotate, and the sliding rod 53 is used to limit the mounting seat 9, thereby increasing the stability of the mounting seat 9 when moving.

[0048] like Figures 1 to 12 As shown, the outer wall of the hopper 2 is symmetrically fixed with fixing parts 54, the inner walls of the two fixing parts 54 are respectively fixedly connected to the outer walls of the two air ducts 34, and a load-bearing plate 55 is fixedly installed on one side of the base 1, and the two collecting boxes 49 are both located above the load-bearing plate 55; the air duct 34 is connected to the hopper 2 through the fixing parts 54 to prevent the air duct 34 from moving, shaking or deforming during use, thereby ensuring the stability of the pipeline system and preventing the air duct 34 from being damaged. The load-bearing plate 55 is used to support the collecting box 49 and reduce the pressure on the placement seat 29.

[0049] Working principle: When conducting the inspection, place the floral white tea to be inspected on the inner side of the hopper 2, and then start the device to conduct the inspection. After the device is started, the driving motor 13 drives the driving shaft 14 to rotate, and the driving shaft 14 drives the adsorption roller 3 to move through the rotating seat 15 and the mounting seat 9 and other structures. When the adsorption roller 3 passes through the tooth B18, the tooth B18 will mesh with the tooth A17. Through the cooperation of the tooth B18 and the tooth A17, the rotary joint 5 drives the adsorption roller 3 to rotate. At the same time, under the action of the negative pressure machine 10, the adsorption roller 3 adsorbs the floral white tea on the surface of the adsorption roller 3 through the adsorption hole 4 while rotating. When the adsorption roller When the suction roller 3 passes through the tooth C37, the tooth C37 will mesh with the tooth A17. Under the action of the tooth C37, the suction roller 3 will rotate again, and the fan 35 will draw in the external air to generate an airflow. The airflow is transported to the inner side of the air guide plate 33 through the air guide pipe 34, and then the airflow of the air guide plate 33 is finally ejected through the air jet hole 36. The ejected airflow blows on the surface of the rotating suction roller 3, and the excess white tea away from the suction hole 4 is blown off. The suction roller 3 continues to move after passing under the air guide plate 33. As the suction roller 3 continues to move, the top block 56 will squeeze the receiving block 21, thereby causing the arc-shaped telescopic shaft 22 and the arc-shaped elastic member 25 to shrink. At this time, the spectrum The collection plate 27 is located on the outside of the adsorption roller 3. As the adsorption roller 3 continues to move, the tooth A17 will mesh with the tooth plate A28, so that the adsorption roller 3 will rotate during the contraction of the arc-shaped telescopic shaft 22. When the adsorption roller 3 rotates, the spectrum collection plate 27 detects the white tea attached to the surface of the adsorption roller 3. When the detection is completed, the drive motor 13 drives the adsorption roller 3 to move in the opposite direction. When the top block 56 leaves the receiving block 21, the drive motor 13 stops rotating, and the automatic telescopic rod 45 extends to push the adsorption roller 3 to move in the direction of the tooth plate B31. When the tooth A17 meshes with the tooth plate B31, the adsorption roller 3 will rotate, and the negative pressure machine 10 will stop working at the same time. When the adsorption roller 3 rotates, the white tea attached to the surface of the adsorption roller 3 will fall off and fall into the collecting box 49 for collection. When the white tea falls completely, the automatic telescopic rod 45 is reset, and the adsorption roller 3 continues to reverse. When the adsorption roller 3 moves to the material-discharging plate 40, it will push the material-discharging plate 40 to move. When the slider 39 is pushed to the end of the arc-shaped slide groove 38, the adsorption roller 3 starts to rotate forward again. When the adsorption roller 3 rotates forward, the material-discharging plate 40 will be pulled to move by the magnetic force of the magnet B44 and the magnet A42. When the slider 39 is pulled to the end of the other end of the arc-shaped slide groove 38, the magnet B44 and the magnet A42 are separated by the restriction of the arc-shaped slide groove 38.
