Description

Technical Field

[0001] The invention relates to the technical field of tea fermentation, in particular to a tea fermentation device capable of automatically turning materials. Background Art

[0002] Tea fermentation equipment is a key equipment in tea processing. Its core function is to create an ideal fermentation environment for tea. This environment requires precise control of temperature, humidity and oxygen supply to ensure that the chemical reaction in the tea can proceed smoothly, thereby generating the unique aroma and taste of tea. Tea fermentation equipment needs to be corrosion-resistant, easy to clean and maintain. Corrosion-resistant materials such as stainless steel or plastic are often used. These devices are usually equipped with temperature and humidity sensors, as well as humidification, heating and ventilation components. They may also include automated control systems to achieve more precise control and monitoring to ensure the stability and consistency of the fermentation environment. At the same time, the design of the equipment also needs to take into account the convenience and safety of operation to ensure the safety of production personnel and improve production efficiency. During the fermentation process, tea leaves usually need to be turned over regularly to adjust the temperature and humidity in the tea pile, promote oxygen exchange and even out the fermentation degree. Existing tea fermentation devices usually use a stirring rod to stir the tea leaves to turn the tea leaves. The stirring process can easily cause damage to the tea leaves, and the turning effect is not good. The lower layer of tea leaves may not be turned over enough, and the tea leaves after turning are not evenly spread. There may be a situation where the local distribution is too thick or too thin. In places where the pile is too thick, the tea pile core lacks oxygen and heats up, which can easily lead to burning of the pile and the growth of miscellaneous bacteria. In places where the pile is too thin, water is lost quickly, enzyme activity is reduced and oxidation is insufficient, resulting in uneven fermentation of the tea leaves as a whole, reducing the fermentation quality of the tea leaves and affecting the taste of the tea leaves. To this end, we propose a tea fermentation device that can automatically turn the tea leaves over. Summary of the invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-11The present invention provides a technical solution: a tea fermentation device capable of automatically turning materials, comprising a fermentation box 1, a control device 2 arranged at the upper end of the fermentation box 1 for controlling the internal temperature and humidity thereof, and a liquid spraying device 3 arranged inside the fermentation box 1 for spraying enzyme liquid to ferment the tea leaves (the control device 2 and the liquid spraying device 3 are both existing known structures, so the present invention will not be further described). The liquid spraying device 3 can atomize the enzyme liquid and spray it into the fermentation box 1, so that the tea leaves and the enzyme liquid are mixed and fermented. A plurality of fermentation frames 4 are arranged in the fermentation box 1, and each fermentation frame 4 is provided with a cover plate 9 at both upper and lower ends, and each cover plate 9 is provided with a plurality of air holes 10. The atomized enzyme liquid can enter the fermentation frame 4 through the air holes 10 and mix with the tea leaves. Limiting bars 5 for limiting the position of the cover plate 9 are provided on the upper and lower sides of the fermentation frame 4. A number of positioning magnetic blocks 6 are fixedly installed on both sides of each cover plate 9 and on each limiting bar 5. The positioning magnetic blocks 6 on both sides of the cover plate 9 correspond to the positioning magnetic blocks 6 on the limiting bar 5 one by one and are magnetically attracted to each other. The limiting of the limiting bar 5 can limit the cover plate 9 to the upper and lower ends of the fermentation frame 4. At the same time, the cover plate 9 is fixed by the magnetic attraction between the positioning magnetic blocks 6 on both sides of the cover plate 9 and the positioning magnetic blocks 6 on the limiting bar 5, so as to prevent tea from spilling out during the turning process of the fermentation frame 4 and facilitate the installation of the cover plate 9 to the corresponding position. Plug-ins 7 are fixedly installed on both sides of each fermentation frame 4, and a number of snap rings 11 matching the plug-ins 7 are provided on the inner walls on both sides of the fermentation box 1. The plug-ins 7 correspond one to one, and a telescopic rod 13 is fixedly installed at one end of each clamp ring 11. A plurality of sleeves 14 are arranged in the inner wall of one side of the fermentation box 1, and a plurality of annular blocks 37 are arranged in the inner wall of the other side. The sleeves 14 and the annular blocks 37 correspond one to one with the fermentation frame 4. One end of the telescopic rod 13 is fixedly installed on the corresponding sleeve 14 and the annular block 37 respectively. The end of each plug-in 7 is arranged in a wedge shape, and a card slot 12 matching the plug-in 7 is arranged in each clamp ring 11. A magnetic block 8 is fixedly installed on the end of each plug-in 7 and the inner wall of each card slot 12. The magnetic block 8 at the end of the plug-in 7 is magnetically attracted to the magnetic block 8 on the inner wall of the card slot 12, and the magnetic attraction force between the two magnetic blocks 8 is greater than the elastic force of the telescopic rod 13, so that the plug-ins 7 on both sides of the fermentation frame 4 are clamped. After aligning with the corresponding grooves 12 on the two snap rings 11, the fermentation frame 4 is pushed into the fermentation box 1. Since the end of the plug-in 7 is set to be wedge-shaped, after the plug-in 7 contacts the snap ring 11, the snap rings 11 on both sides will retract toward the inner wall of the fermentation box 1 and compress the telescopic rod 13. When the plug-in 7 is aligned with the groove 12, the telescopic rod 13 will pop out again, so that the plug-in 7 is inserted into the groove 12, and the fermentation frame 4 is fixed to the snap rings 11 on both sides through the magnetic attraction force between the magnetic attraction block 8 at the end of the plug-in 7 and the magnetic attraction block 8 on the inner wall of the groove 12. When taking out the fermentation frame 4, the fermentation frame 4 is pulled out of the fermentation box 1, and the corresponding snap rings 11 on both sides will retract toward the inner wall of the fermentation box 1 again under the action of the inclined surface of the end of the plug-in 7. After the fermentation frame 4 is taken out, the elastic force of the telescopic rod 13 resets the snap ring 11 again.

[0019] A plurality of first cylinders 22 are fixedly installed in the inner wall of the fermentation box 1, and the first cylinders 22 correspond to the fermentation frames 4 one by one. A connecting rod 23 is fixedly installed at the output end of each first cylinder 22, and a rack 27 is provided at one end of each connecting rod 23. A gear 15 matching the rack 27 is fixedly installed on each sleeve 14. A plurality of sliders 18 are slidably installed up and down in the inner wall of the fermentation box 1, and the sliders 18 correspond to the sleeves 14 one by one. An elastic rod 19 is fixedly installed on one side of each slider 18, and a plug rod 20 is fixedly installed on one end of each elastic rod 19. A positioning hole 16 for limiting the plug rod 20 is provided on each sleeve 14, and each positioning hole 16 passes through the sleeve 14. An elastic block 21 is fixedly installed on each plug rod 20, and each gear A stopper 28 is fixedly installed on one side of the bar 27, and each elastic block 21 is located on the movement trajectory of the corresponding stopper 28. The elastic force of the elastic rod 19 is less than the thrust required for the elastic block 21 to deform, and each elastic rod 19 is always in a compressed state. A sliding magnetic rod 29 is fixedly installed on one side of each rack 27. A plurality of circular grooves 30 for limiting the sliding magnetic rod 29 are arranged in the inner wall of the fermentation box 1. The circular grooves 30 correspond to the sliding magnetic rods 29 one by one. A magnetic strip 31 that is magnetically attracted to the sliding magnetic rod 29 is fixedly installed on the top inner wall of the initial end of each circular groove 30. When the tea leaves need to be turned over, the first cylinder 22 will be controlled to extend, and the first cylinder 22 will push the connecting rod 23 to drive the rack 27 to move. In the initial state, the insertion rod 20 is elastically The push of the magnetic rod 19 is inserted into the positioning hole 16 to prevent the uneven distribution of tea leaves in the fermentation frame 4 from driving the clamping ring 11 and the sleeve 14 to rotate. In the initial state, the sliding magnetic rod 29 is driven by the magnetic attraction of the magnetic strip 31 to drive the rack 27 to move upward, and the sliding magnetic rod 29 is located at the initial end of the circular groove 30. When the first cylinder 22 is extended, the rack 27 will move laterally along the horizontal groove body at the upper end of the circular groove 30, and the rear stopper 28 will contact the elastic block 21. Since the elastic force of the elastic rod 19 is less than the thrust required for the elastic block 21 to deform, the stopper 28 will drive the elastic block 21 and the insertion rod 20 to move together after contacting the elastic block 21, and the elastic rod 19 will be compressed. The insertion rod 20 no longer limits the sleeve 14, and the rack 27 will move to the gear 15. The first cylinder 22 is in meshing state, and as the first cylinder 22 is continuously extended, the gear 15 will drive the sleeve 14, the clamping ring 11 and the fermentation frame 4 to rotate, so that the tea leaves in the fermentation frame 4 are turned over, achieving a good turning effect, which is convenient for the tea leaves to fully contact with the atomized enzyme liquid produced by the liquid spraying device 3, and ensures that the fermentation can proceed smoothly. When the first cylinder 22 is completely extended, the gear 15 will drive the sleeve 14 and the fermentation frame 4 to rotate half a circle, so that the fermentation frame 4 drives the tea leaves inside thereof to turn over completely. At this time, the elastic rod 19 will no longer be able to shrink, the elastic block 21 will be deformed and no longer limited by the blocking rod 28. The elastic force of the elastic rod 19 causes the insertion rod 20 to be inserted into the positioning hole 16 again, and is inserted from the other end of the positioning hole 16, again preventing the sleeve 14 and the fermentation frame 4 from rotating.At the same time, the sliding magnetic rod 29 will move to the end of the upper end of the return groove 30, and the rack 27 will move downward along the right vertical groove of the return groove 30 due to its own gravity. When the first cylinder 22 retracts and drives the rack 27 to move in the opposite direction, the rack 27 will no longer mesh with the gear 15, and the blocking rod 28 will no longer contact the elastic block 21. When the first cylinder 22 retracts, the rack 27 will move horizontally along the lower horizontal groove of the return groove 30. After the first cylinder 22 retracts, the sliding magnetic rod 29 will move to the lower end of the left vertical groove of the return groove 30, and will be driven by the magnetic attraction of the magnetic strip 31 to move the rack 27 upward and reset.

[0020] A guide magnetic rod 17 is fixedly installed at one end of each sleeve 14, and a plurality of first annular grooves 34 for limiting the guide magnetic rod 17 and a plurality of second annular grooves 36 for limiting the annular blocks 37 are respectively arranged in the inner walls on both sides of the fermentation box 1. A second cylinder 32 is fixedly installed in the inner wall of the fermentation box 1, and a plurality of limit frames 33 for limiting the guide magnetic rod 17 are fixedly installed at the output end of the second cylinder 32. The limit frames 33 correspond to the guide magnetic rods 17 one by one. Guide magnetic blocks 35 magnetically attracted to the guide magnetic rods 17 are fixedly installed on both sides of each first annular groove 34, and every two corresponding guide magnetic blocks 35 are rotationally symmetrically distributed on both sides of the first annular groove 34. After the first cylinder 22 is extended, the second cylinder 32 will perform reciprocating telescopic motion, and drive the limit frame 33 to perform up and down reciprocating motion, through the limit frame 33 to limit the guide magnetic rod 17, and the first The annular groove 34 limits the guide magnetic rod 17, and the guide magnetic rod 17 will drive the corresponding sleeve 14 and the fermentation frame 4 to perform circular motion. Since the elastic rod 19 is always in a compressed state, when the sleeve 14 performs circular motion, it will drive the insertion rod 20 to move synchronously, the slider 18 slides up and down, and the elastic rod 19 is extended and retracted accordingly, preventing the sleeve 14 from driving the fermentation frame 4 to rotate again. During the rotation of the fermentation frame 4, the tea leaves inside it are easy to accumulate at one end of the fermentation frame 4. When the fermentation frame 4 performs circular motion, the tea leaves accumulated inside can move to the other end, so that the tea leaves are more evenly distributed in the fermentation frame 4, thereby improving the fermentation effect. Moreover, since the guide magnetic blocks 35 that are magnetically attracted to the guide magnetic rod 17 are symmetrically arranged on both sides of the first annular groove 34, the guide magnetic rod 17 will be subjected to the magnetic attraction of the guide magnetic blocks 35 during the circular motion and move unidirectionally along the first annular groove 34 without being able to return.

[0021] A limiting rod 38 is rotatably installed on one side of the clamping ring 11 corresponding to each annular block 37, and a telescopic strip 39 is fixedly installed on one end of each limiting rod 38, and an arc block 40 is fixedly installed on one end of each telescopic strip 39. A limiting groove 41 for limiting the arc block 40 is provided on the inner wall of each second annular groove 36, and each limiting groove 41 is spirally arranged, and its head end and the tail end are connected to a telescopic groove 42 for releasing the limit of the arc block 40, and a telescopic groove 42 at the head end of each limiting groove 41 is fixedly installed on the inner wall of the telescopic groove 42 The magnetic attraction member 43 is used to generate a magnetic attraction force on the arc block 40. The magnetic attraction force of the magnetic attraction member 43 on the arc block 40 is greater than the elastic force of the telescopic strip 39. When the fermentation frame 4 drives the clamping ring 11 to perform a circular motion, the annular block 37 will also perform a circular motion in the second annular groove 36. In the initial state, the arc block 40 is affected by the magnetic attraction force of the magnetic attraction member 43 and will enter the telescopic groove 42 at the head end of the limiting groove 41 and stretch the telescopic strip 39. When the clamping ring 11 performs a circular motion, it will also drive the arc block 40 to perform a circular motion. The arc block 40 will The arc block 40 will drive the clamping ring 11 to move into the second annular groove 36. Since the magnetic attraction between the two magnetic blocks 8 is greater than the elastic force of the telescopic rod 13, the plug-ins 7 on both sides of the fermentation frame 4 will move synchronously with the corresponding clamping ring 11, so that the fermentation frame 4 moves in a circular motion while moving into the second annular groove 36, and the telescopic rods 13 on both sides are correspondingly extended and retracted. After the second cylinder 32 completes the extension and retraction, the fermentation frame 4 is The tea leaves will be evenly spread horizontally. At this time, the arc block 40 will move into the telescopic groove 42 at the tail end of the limiting groove 41. The arc block 40 will be pulled back by the elastic force of the telescopic strip 39, and the limit of the arc block 40 by the limiting groove 41 will be released. The elasticity of the telescopic rod 13 will control the fermentation frame 4 to move out of the second annular groove 36 and reset. The elastic force of the telescopic rod 13 will make the fermentation frame 4 perform multiple longitudinal reciprocating motions and then gradually return to rest. The fermentation frame 4 can evenly spread the tea leaves inside it longitudinally during the multiple longitudinal reciprocating motions.

[0022] A plurality of winding shafts 24 are rotatably installed in the fermentation box 1, and the winding shafts 24 correspond to the connecting rods 23 one by one, and one end of each winding shaft 24 is fixedly connected to the inner wall of the fermentation box 1 with a torsion spring 25, and a dust collecting cloth 26 is rolled up on each winding shaft 24, and one end of each dust collecting cloth 26 is fixedly installed on the corresponding winding shaft 24, and the other end is fixedly connected to the corresponding connecting rod 23. During the extension of the first cylinder 22, one end of the dust collecting cloth 26 can be driven to move, and the winding shaft 24 can be rotated, and the torsion spring 25 rotates to store force. After the first cylinder 22 is extended, the dust collecting cloth 26 will be flattened. At the lower end of the fermentation frame 4, during the rotation, circular motion and longitudinal reciprocating motion of the fermentation frame 4, impurities and fragments in the tea leaves inside it will be shaken out through the air holes 10 on the cover plate 9, and the dust collecting cloth 26 can collect them to prevent the impurities in the upper fermentation frame 4 from being shaken into the lower fermentation frame 4, thereby improving the quality of the tea leaves in the fermentation frame 4. After the fermentation frame 4 returns to rest, the first cylinder 22 will retract, and the winding shaft 24 will rotate under the elastic force of the torsion spring 25 to wind and reset the dust collecting cloth 26, and the impurities on the dust collecting cloth 26 will fall to the bottom side of the fermentation box 1 for easy collection.

[0023] Specifically, first, the cover plate 9 is installed to the lower end of the fermentation frame 4 through the limitation of the limit bar 5, and the cover plate 9 is fixed by the magnetic attraction between the positioning magnetic blocks 6 on both sides of the cover plate 9 and the positioning magnetic blocks 6 on the limit bar 5, and then the tea leaves are put into the fermentation frame 4, and the cover plate on the upper end of the fermentation frame 4 is installed, and the plug-ins 7 on both sides of the fermentation frame 4 are aligned with the grooves 12 on the corresponding two clamping rings 11, and the fermentation frame 4 is pushed into the fermentation box 1. Since the end of the plug-in 7 is set to be wedge-shaped, after the plug-in 7 contacts the clamping ring 11, the clamping rings 11 on both sides will retract toward the inner wall of the fermentation box 1, and the telescopic rod 13 will be compressed. When the plug-in 7 is aligned with the groove 12, the telescopic rod 13 will pop out again, so that the plug-in 7 is inserted into the groove 12, and the magnetic suction block 8 at the end of the plug-in 7 is magnetically attracted to the inner wall of the groove 12. The magnetic attraction between the blocks 8 fixes the fermentation frame 4 to the clamping rings 11 on both sides, and then the temperature, humidity and fermentation time in the fermentation box 1 are set by the regulating device 2. After the box door is closed, the liquid spraying device 3 sprays atomized enzyme liquid to mix with the tea leaves to ferment the tea leaves. When the tea leaves need to be turned over, the first cylinder 22 will be controlled to extend, and the first cylinder 22 will push the connecting rod 23 to drive the rack 27 to move. The rack 27 will move laterally along the transverse groove body at the upper end of the circular groove 30, and then the stopper 28 will contact the elastic block 21. After the stopper 28 contacts the elastic block 21, it will drive the elastic block 21 and the insertion rod 20 to move together, and compress the elastic rod 19. The insertion rod 20 no longer limits the sleeve 14, and at the same time, the rack 27 will move to a meshing state with the gear 15, and along with the first As the first cylinder 22 is continuously extended, the gear 15 will drive the sleeve 14, the clamping ring 11 and the fermentation frame 4 to rotate, so that the tea leaves in the fermentation frame 4 are turned over, so that the tea leaves are fully contacted with the atomized enzyme liquid produced by the liquid spraying device 3. When the first cylinder 22 is completely extended, the gear 15 will drive the sleeve 14 and the fermentation frame 4 to rotate half a circle, so that the fermentation frame 4 drives the tea leaves inside thereof to be completely turned over. At this time, the elastic rod 19 will no longer be able to shrink, and the elastic block 21 will be deformed and no longer limited by the blocking rod 28. The elastic force of the elastic rod 19 causes the insertion rod 20 to be inserted into the positioning hole 16 again, preventing the sleeve 14 and the fermentation frame 4 from rotating again. At the same time, the sliding magnetic rod 29 will move to the end of the upper end of the groove body of the circular groove 30, and the rack 27 will be driven by its own gravity to move vertically along the right side of the circular groove 30 When the first cylinder 22 is retracted, the rack 27 will move horizontally along the horizontal groove body at the lower end of the circular groove 30. After the first cylinder 22 is completely retracted, the sliding magnetic rod 29 will move to the lower end of the vertical groove body on the left side of the circular groove 30, and will be driven by the magnetic attraction of the magnetic strip 31 to move the rack 27 upward and reset. After the first cylinder 22 is completely extended, the second cylinder 32 will perform reciprocating telescopic motion and drive the limit frame 33 to reciprocate up and down. The guide magnetic rod 17 will drive the corresponding sleeve 14 and the fermentation frame 4 to perform circular motion. When the sleeve 14 performs circular motion, it will drive the insertion rod 20 to move synchronously to prevent the sleeve 14 from driving the fermentation frame 4 to rotate again. When the fermentation frame 4 performs circular motion, the tea leaves accumulated inside it can move to the other end.The tea leaves are spread more evenly in the fermentation frame 4, and the fermentation effect is improved. When the fermentation frame 4 drives the clamping ring 11 to perform a circular motion, the annular block 37 will also perform a circular motion in the second annular groove 36. When the clamping ring 11 performs a circular motion, it will also drive the arc block 40 to perform a circular motion. The arc block 40 will enter the limiting groove 41 and cannot retract, and perform a spiral motion along the limiting groove 41. The arc block 40 will drive the fermentation frame 4 to perform a circular motion while moving into the second annular groove 36, and make the telescopic rods 13 on both sides to perform corresponding telescopic motion. After the second cylinder 32 completes the telescopic motion, the arc block 40 will move into the telescopic groove 42 at the tail end of the limiting groove 41, and the arc block 40 will be pulled back by the elastic force of the telescopic strip 39, releasing the limit of the limiting groove 41 on the arc block 40, and the elastic force of the telescopic rod 13 will make the fermentation frame 4 Multiple longitudinal reciprocating movements make the tea leaves inside it evenly spread longitudinally. During the extension of the first cylinder 22, one end of the dust collecting cloth 26 can be driven to move, and the reel 24 can be rotated. The torsion spring 25 rotates and accumulates force. After the first cylinder 22 is fully extended, the dust collecting cloth 26 will be spread flat on the lower end of the fermentation frame 4. During the rotation, circular motion and longitudinal reciprocating motion of the fermentation frame 4, the impurities and fragments in the tea leaves inside it will be shaken out through the air holes 10 on the cover plate 9. The dust collecting cloth 26 can collect them to prevent the impurities in the upper fermentation frame 4 from being shaken off into the lower fermentation frame 4, thereby improving the quality of the tea leaves in the fermentation frame 4. When the first cylinder 22 retracts, the reel 24 is rotated by the elastic force of the torsion spring 25 to rewind and reset the dust collecting cloth 26. The impurities on the dust collecting cloth 26 fall to the bottom side of the fermentation box 1 for easy collection.
