Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and particularly relates to a double-rotation tumbling type tea rolling device. Background Art

[0002] During the tea processing, it is necessary to roll the tea leaves. Through external force, the tea leaves are formed into a tight and curved shape, the tea strips are rolled tightly, the volume is reduced, laying a good foundation for frying into strips. Appropriate destruction of leaf tissue and material transformation cause the tea juice to overflow and adhere to the surface of the tea leaves, making the tea convenient for brewing. Traditional tea is rolled manually, and it is necessary to repeatedly roll the tea leaves into a ball and then shake them loose until the tea leaves are rolled into appropriate strips. Due to the long rolling time, it is labor-consuming, causes great pressure on the operator's wrist, and the manual rolling efficiency is slow.

[0003] Existing tea rolling machines usually have an open rolling structure. When rotating and rolling, the tea leaves are prone to splash, and being exposed to air accelerates oxidation and browning. When loading and unloading, the machine stops and manual feeding and discharging are required, which is time-consuming and increases the risk of cross-contamination.

[0004] Traditional rolling machines mostly adopt a single-sided and one-way rolling structure. Due to the single rotation direction, the tea leaves are only subjected to one-way extrusion, and it is impossible to simulate the complex operations of "pushing - squeezing - turning" in manual rolling. As a result, the finished product tea strips are prone to looseness, and the tender leaves are more likely to be broken, affecting the appearance and extraction quality of the tea. Moreover, it is not easy to adjust the rolling pressure, it is difficult to adapt to the characteristics of different teas, and it is easy to exacerbate breakage and caking. Summary of the Invention

Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 and Figure 5 shown, the present invention provides a double-rotation tumbling type tea rolling device, including a rolling outer cylinder 10, having an inner side wall 11 for rolling tea, and the rolling outer cylinder 10 can rotate self. A rolling inner cylinder 20 is coaxially arranged inside the rolling outer cylinder 10 and has an outer side wall 21 for rolling tea. The rolling inner cylinder 20 rotates around the axis of the rolling outer cylinder 10 inside the rolling outer cylinder 10, and a rolling channel 30 for accommodating tea is arranged between the inner side wall 11 and the outer side wall 21. A driving motor 40, the driving shaft 41 of the driving motor 40 is connected to a self-rotating rod 42 and an eccentric rod 43 through a gear assembly 50. The self-rotating rod 42 is axially connected to the rolling outer cylinder 10, and the eccentric rod 43 is axially connected to the rolling inner cylinder 20.

[0022] The present invention adopts a coaxial bidirectional rotation form to form a tea rolling mechanism with a tumbling structure, and cooperates with the internal and external differential motion to improve the rolling efficiency. At the same time, the rolling roller forms an adjustable tumbling structure through a double telescopic structure, tumbles the tea while rolling, which is beneficial to simulating the form of repeatedly shaking and rolling during manual rolling, making the tea roll more evenly, and enabling the tea juice to adhere to the tea surface more evenly, thereby improving the rolling effect and the quality of tea processing.

[0023] The driving motor 40 controls the gear assembly 50 to drive the self-rotating rod 42 and the eccentric rod 43 to rotate respectively through the driving shaft 41, thereby controlling the rotation of the rolling outer cylinder 10 and the rolling inner cylinder 20. The rolling inner cylinder 20 is eccentrically arranged inside the rolling outer cylinder 10, so that the rolling inner cylinder 20 and the rolling outer cylinder 10 form a differential rotation, and the tea reaches the purpose of rolling under the action of the inner side wall 11 and the outer side wall 21 in the rolling channel 30, which is beneficial to solving the problem that the traditional rolling machine only rotates in one direction, making the tea force single and resulting in uneven and loose strip shape.

[0024] As Figure 2 and Figure 7 shown, both the rolling outer cylinder 10 and the rolling inner cylinder 20 are cylinder structures with closed ends, and a door structure 60 that can be opened and closed is arranged on the side wall of the rolling outer cylinder 10. The door structure 60 is used for loading tea or taking out tea. The door body structure 60 includes a feeding port 61 opened on the outer rolling cylinder 10 for the tea leaves to pass through. A material door 62 is rotatably connected to the outer rolling cylinder 10 through a rotating shaft. After the material door 62 rotates around its connection with the outer rolling cylinder 10, the feeding port 61 is enclosed inside.

[0025] Through the closed structure of the outer rolling cylinder 10 and the inner rolling cylinder 20, it is beneficial to enclose the tea leaves in the rolling channel 30 for rolling operations, thereby reducing the situation of tea leaves splashing or accelerating oxidation during the rolling process, facilitating the reduction of the possible cross-contamination of tea leaves, and being more conducive to maintaining the quality of tea leaves and slowing down the speed of tea leaves oxidizing and discoloring.

[0026] By opening the material door 62, it is beneficial to feed or discharge the tea leaves through the feeding port 61. By adjusting the rotation angle of the outer rolling cylinder 10, the feeding port 61 is positioned at the top or bottom for loading or removing tea leaves.

[0027] Such as Figure 1 、 Figure 5 and Figure 6 As shown in the figure, the gear assembly 50 includes a rotating gear 51, a reversing gear 52, and a star gear 53. The star gear 53 is fixed on the drive shaft 41. The rotating gear 51 is fixed at the end of the self-rotating rod 42 and meshes with the star gear 53. The reversing gear 52 is fixed outside the eccentric rod 43 and is connected to the star gear 53 through a linkage assembly 70.

[0028] The reversing gear 52 forms a differential rotation structure with the rotating gear 51 through the linkage assembly 70. The reversing gear 52 is meshed with the star gear 53 through the linkage assembly 70. During the rolling process, the reversing gear 52 can be meshed or separated from the star gear 53 through the linkage assembly 70, enabling the outer rolling cylinder 10 to control the synchronous rotation or stop rotation of the inner rolling cylinder 20 when rotating, facilitating intermittent pauses according to the rolling degree of the tea leaves, better simulating the rhythm of manual rolling, being conducive to better adsorption of tea juice and tea leaves, and achieving the purpose of improving the rolling quality of tea leaves through rhythmic rolling.

[0029] It is beneficial to switch the combined rotation of the outer rolling cylinder 10 and the inner rolling cylinder 20, enabling the outer rolling cylinder 10 and the inner rolling cylinder 20 to rotate simultaneously, or the outer rolling cylinder 10 to rotate alone, facilitating adjustment and use according to actual operation requirements.

[0030] Such as Figure 6 As shown in the figure, the linkage assembly 70 includes an electric push rod 71, a movable rod 72, a movable shaft 73, a transmission gear 74, and a driven gear 75. The movable end of the electric push rod 71 is connected to the movable shaft 73 through the movable rod 72, and one end of the movable shaft 73 passes through the interiors of the driven gear 75 and the transmission gear 74 respectively; Among them, the transmission gear 74 is meshed with the star gear 53, and the driven gear 75 is meshed with the reversing gear 52.

[0031] The linkage component 70 is translated along the length direction of the rolling inner cylinder 20 and then meshed and connected with the star gear 53 and the reverse gear 52 respectively. The electric push rod 71 drives the movable rod 72 to translate, so that the transmission gear 74 and the driven gear 75 move to one side, thereby controlling the meshing or separation of the rolling inner cylinder 20 and the star gear 53; When the transmission gear 74 and the driven gear 75 move to the meshing positions with the star gear 53 and the reverse gear 52, the star gear 53 drives the reverse gear 52 and the rotating gear 51 at the same time, so that the rolling outer cylinder 10 and the rolling inner cylinder 20 rotate at the same time; When the transmission gear 74 and the driven gear 75 move to the other side and the transmission gear 74 and the driven gear 75 are separated from the star gear 53 and the reverse gear 52, at this time the star gear 53 cannot drive the reverse gear 52, so that while the rolling outer cylinder 10 is rotating, the rotation of the rolling inner cylinder 20 can be controlled to stop; During the rotation of the rolling outer cylinder 10 on the tea leaves, the kneading of the tea leaves can be stopped, which is beneficial to the rhythmic tea kneading operation and can help the tea leaves better absorb the kneading.

[0032] At the same time, through the pitch of the driven gear 75, it is beneficial to adjust the rotation speed of the rolling inner cylinder 20, so that the rolling inner cylinder 20 and the rolling outer cylinder 10 rotate at a differential speed, thereby adjusting the tea kneading efficiency.

[0033] Such as Figure 1 and Figure 2 As shown, one end of the self-rotating rod 42 is connected to the rolling outer cylinder 10 through the fixing frame 12, and the eccentric rod 43 passes through the inside of the self-rotating rod 42 and one end of the rolling outer cylinder 10 and is connected to the rolling inner cylinder 20.

[0034] One end of the rolling outer cylinder 10 is connected to the driving motor 40 through the self-rotating rod 42 and the gear assembly 50 to move. The eccentric rod 43 passes through the inside of the self-rotating rod 42 and is connected to the same driving motor 40 through the gear assembly 50 to move, so that the rolling outer cylinder 10 and the rolling inner cylinder 20 can be controlled to move by the same driving motor 40, which is beneficial to reducing the setting of the driving motor 40, thereby being beneficial to reducing the production cost and maintenance cost, reducing the overall volume and occupied space of the device, and being beneficial to more application scenarios.

[0035] The rotation rod 42 and the eccentric rod 43 facilitate the connection between the driving motor 40 and the gear assembly 50, enabling the inner kneading cylinder 20 to rotate around the rotation rod 42. As a result, the inner kneading cylinder 20 and the outer kneading cylinder 10 rotate coaxially. Since the inner kneading cylinder 20 is eccentrically installed within the outer kneading cylinder 10, when the inner kneading cylinder 20 rotates, it drives the tea leaves to rub within the outer kneading cylinder 10, causing the tea leaves to be kneaded within the kneading channel 30. This can keep the tea leaves concentrated at the kneading position for repeated kneading, reducing the uneven accumulation of tea leaves during conventional one-way kneading, which may otherwise lead to over-kneading of some tea leaves and insufficient kneading of others. Thus, it is beneficial to improve the tea kneading effect.

[0036] As Figure 1 and Figure 5 shown, at the other end of the outer kneading cylinder 10, a rotation sub-rod 13 is provided through a fixing bracket 12. The rotation sub-rod 13 is disposed opposite to the rotation rod 42. At the other end of the inner kneading cylinder 20, an eccentric sub-rod 14 passing through the inner kneading cylinder 20 is provided. Both the rotation sub-rod 13 and the eccentric sub-rod 14 are installed on the sub-bracket 15 through bearings.

[0037] The other ends of the outer kneading cylinder 10 and the inner kneading cylinder 20 are respectively installed on the sub-bracket 15 through the rotation sub-rod 13 and the rotation rod 42, and cooperate with the driving motor 40 and the gear assembly 50 for movement. Reducing the setting of the driving motor 40 can lower production costs. The sub-bracket 15 and the gear assembly 50 can be selected on the sub-bracket 15 to cooperate in movement, which is beneficial to achieving a more stable kneading mechanism.

[0038] As Figure 3 、 Figure 5 、 Figure 7 and Figure 9 shown, the inner kneading cylinder 20 is composed of two sets of symmetrically arranged fixed roller sheets 22 and two sets of symmetrically arranged movable roller sheets 23. Both ends of the cylinder formed by the two sets of fixed roller sheets 22 and the two sets of movable roller sheets 23 are connected and sealed by sealing cylinder sheets 24. At least one set of first double telescopic rods 25 is provided within the inner kneading cylinder 20. The two movable ends of the inner kneading cylinder 20 are connected to the two sets of fixed roller sheets 22 through support bars 26; Among them, within the inner kneading cylinder 20, a turning mechanism 80 capable of passing through the fixed roller sheets 22 is provided. The turning mechanism 80 has turning rods 81 for turning the tea leaves. The turning rods 81 can enter the kneading channel 30 to the surface of the inner sidewall 11 to disperse and turn the tea leaves.

[0039] The two groups of fixed roller pieces 22 are telescopically moved in a translational manner in the diameter direction of the rolling inner cylinder 20. The first double-acting telescopic rod 25 drives the fixed roller pieces 22 to move translationally, which is beneficial to adjusting the distance between the outside of the fixed roller pieces 22 and the rolling outer cylinder 10, further adjusting the shape of the rolling channel 30, and increasing or decreasing the distance between the inner side wall 11 and the outer side wall 21. It can be adjusted according to the degree of tea rolling or the requirements of different tea rolling, which is beneficial to flexible adjustment according to the characteristics of different teas, thereby reducing the situation of mechanical damage to different teas and reducing the situation that some teas are easily broken and affect the tea quality.

[0040] While the two groups of fixed roller pieces 22 are telescoping, the movable roller piece 23 and the sealing cylinder piece 24 adapt and deform following the adjustment of the fixed roller pieces 22. The movable roller piece 23 and the sealing cylinder piece 24 are made of materials such as silica gel or rubber, which have a certain elasticity and can be deformed to a certain extent when subjected to external extrusion. When there is no external extrusion, it is beneficial to restore the shape and has a certain sealing property, which is convenient to deform following the adjustment of the fixed roller pieces 22.

[0041] During the rotation process, through the movable adjustment of the rolling inner cylinder 20 and the turning rod 81, the turning rod 81 protrudes outside the rolling inner cylinder 20. Thus, during the rotation of the rolling inner cylinder 20, the turning rod 81 turns the tea leaves, enabling the tea leaves to simulate the steps of manual rolling during the rolling process, repeatedly rolling and turning, further helping the tea leaves to come into contact with the tea juice and achieving a better rolling effect.

[0042] As Figure 3 、 Figure 7 and Figure 8 shown, a second double-acting telescopic rod 82 parallel to the first double-acting telescopic rod 25 is arranged at the central position inside the rolling inner cylinder 20. The two movable ends of the second double-acting telescopic rod 82 are connected to the turning rod 81, and a through groove 22a for the turning rod 81 to pass through is opened on the fixed roller piece 22; Among them, the outside of the fixed roller piece 22 is located inside the through groove 22a, and a sealing plate 22b is connected by a spring shaft. The sealing plate 22b rotates around its connection with the fixed roller piece 22 and closes the through groove 22a inside.

[0043] At the same time, the turning rod 81 telescopically moves on the fixed roller piece 22. During the telescopic process of the fixed roller piece 22, the fixed roller piece 22 slides outside the turning rod 81 through the through groove 22a. When the turning rod 81 maintains its length and the fixed roller piece 22 contracts, the turning rod 81 pushes the sealing plate 22b until the turning rod 81 protrudes outside the fixed roller piece 22. At this time, the distance between the inner side wall 11 and the outer side wall 21 increases, and the turning rod 81 can contact the tea leaves to turn them, which is beneficial to dispersing the agglomerated tea leaves, more conducive to the attachment of tea juice on the surface of the tea leaves, accelerating the absorption of tea juice, and making the tea leaves more conducive to forming strips after multiple rollings.

[0044] When it is necessary to reduce the distance between the inner wall 11 and the outer wall 21, the fixed roller blade 22 is driven by the first double-acting telescopic rod 25 to extend outward, and at the same time, the movable roller blade 23 is stretched and unfolded, so that the distance between the fixed roller blade 22 and the inner wall 11 is reduced, which is beneficial to adjusting the spacing required for tea leaf rolling, facilitating different rolling degrees according to the needs of different tea leaves, and thus improving the rolling effect of different tea leaves.

[0045] The turning rod 81 is driven by the second double-acting telescopic rod 82 to extend or contract, which is beneficial to adjusting the distance between the turning rod 81 and the inner wall 11, and facilitating switching between the rolling and turning actions by using the turning rod 81; When rolling the tea leaves, the second double-acting telescopic rod 82 drives the turning rod 81 to contract inward, so that the turning rod 81 is received in the rolling inner cylinder 20. At this time, the tea leaves are rolled through the rolling channel 30. The second double-acting telescopic rod 82 can drive the turning rod 81 to extend into the rolling channel 30, which is beneficial to increasing the turning of the tea leaves by the turning rod 81, and thus facilitating more flexible adjustment according to the actual operation requirements; When turning the tea leaves, the second double-acting telescopic rod 82 drives the turning rod 81 to extend, so that the turning rod 81 protrudes from the surface of the rolling inner cylinder 20, and the turning rod 81 is used to turn and scatter the tea leaves in the rolling channel 30, thereby helping the tea juice to better adhere to the tea leaves, being able to simulate the operations of manual repeated rolling and scattering, and making the tea leaves more evenly rolled.

[0046] As Figure 2 、 Figure 4 and Figure 10 As shown, a feeding mechanism 90 is arranged at the relative position between the side wall of the rolling outer cylinder 10 and the door structure 60. The feeding mechanism 90 includes an air duct 91 and a blower 92. The air duct 91 communicates with both ends of the rolling outer cylinder 10 through a fixing frame 12 to form a convective disturbance; Among them, the blower 92 is fixed on the outer wall of the rolling outer cylinder 10, and the air outlet side of the blower 92 is communicated with the rolling outer cylinder 10 through the air duct 91. A wind guide groove 12a is opened on the fixing frame 12, and both ends of the wind guide groove 12a are respectively connected to the air duct 91 and the rolling outer cylinder 10.

[0047] The air on one side of the blower 92 is conveyed into the fixing frame 12 through the air duct 91, and the wind is guided through the wind guide groove 12a to both ends of the rolling outer cylinder 10 and enters the rolling channel 30, which is beneficial to controlling the tea leaves to be concentrated in the rolling channel 30, and forming a convective disturbance through air supply on both sides, being beneficial to reducing the situation that the water vapor cannot be discharged during closed rolling, resulting in excessive humidity and over-fermentation, being beneficial to controlling the humidity during tea leaf rolling, and increasing the disturbance of the tea leaves, reducing the accumulation of tea leaves, and thus being beneficial to improving the rolling effect of the tea leaves.

[0048] As Figure 4 andFigure 5 As shown, the drive motor 40 and the linkage assembly 70 are both installed on the main bracket 16. The main bracket 16 and the auxiliary bracket 15 are respectively installed at both ends of the base 17. A conveyor belt 18 is provided on the base 17. The length direction of the conveyor belt 18 is perpendicular to the length direction of the rolling outer cylinder 10, and the width of the conveyor belt 18 is greater than the width of the feed door 62. Baffle plates 19 are provided on both sides of the conveyor belt 18.

[0049] One end of the eccentric rod 43 is movably connected to the main bracket 16 through a bearing, which is beneficial to install and fix the drive motor 40 and the gear assembly 50 through the main bracket 16.
