Description

Technical Field

[0001] This invention belongs to the technical field of tea processing, and more specifically, relates to an energy-saving ball mill for tea processing. Background Technology

[0002] A tea ball mill typically includes a drive mechanism, a drum, and grinding balls inside the drum. The working process involves placing tea leaves into the cavity inside the machine casing. A drive motor then rotates the casing, causing the multiple grinding balls inside to roll and collide with each other, grinding the tea leaves into matcha powder. Finally, the tea powder is unloaded and collected.

[0003] The existing technology for tea processing still has the following shortcomings: In the existing technology, when grinding tea leaves, the tea leaves and grinding balls mainly tumble with the drum. The material tends to concentrate in a local area inside the drum for a long time, especially the uneven distribution in the axial direction. This leads to local accumulation and agglomeration between tea leaves and between tea leaves and grinding balls, affecting the overall uniformity of tea grinding.

[0004] In existing technologies, existing structures are usually based on simple rotating ball mills, lacking mechanisms for actively moving, breaking up, and dynamically repositioning tea leaves. This makes it difficult to disrupt the already formed localized accumulation areas in a timely manner, and tea leaves do not easily enter the effective working area of ​​the grinding balls, thus affecting the ball milling efficiency.

[0005] In existing technologies, tea leaves are subjected to impact, compression, and friction from the grinding balls during ball milling, which easily generates heat. However, existing equipment generally lacks effective heat dissipation and cooling structures for the materials and gases inside the drum. This leads to problems such as adhesion, clumping, and even quality degradation of the tea leaves after the temperature rises, affecting the stability of ball milling.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an energy-saving ball mill for tea processing, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0007] This invention provides an energy-saving ball mill for tea processing, which overcomes the above-mentioned defects in the prior art.

[0008] The purpose and effectiveness of this energy-saving ball mill for tea processing are achieved by the following specific technical means: An energy-saving ball mill for tea processing includes a frame and a drum rotatably mounted on the frame, and further includes: A movable ring is located inside the roller and is circumferentially linked to the roller and can move axially relative to the roller. A spiral frame is disposed inside the movable ring and is circumferentially driven by the movable ring and can be axially displaced relative to the movable ring. Disturbance components are disposed on both sides of the spiral frame; A guiding mechanism is provided between the frame and the movable ring and the spiral frame. The guiding mechanism drives the movable ring and the spiral frame to reciprocate axially as the drum rotates, and the movable ring and the spiral frame move in opposite directions. A driving structure is disposed between the movable ring and the spiral frame, and the driving structure drives the disturbance component to move when the movable ring and the spiral frame are relatively displaced; A cooling structure is provided on the movable ring and the spiral frame to cool the material inside the drum.

[0009] In this solution, through the coordinated operation of the movable ring, spiral frame, disturbance component, guiding mechanism, driving structure and cooling structure, tea leaves can simultaneously achieve ball milling, guiding dispersion, dynamic disturbance and cooling heat dissipation within the drum. This disrupts the local accumulation state of tea leaves within the drum, improves the uniformity of contact between tea leaves and grinding balls, reduces agglomeration and heating problems, and enhances the uniformity of tea ball milling.

[0010] Preferably, the movable ring and the inner wall of the drum are splined together so that the drum drives the movable ring to rotate synchronously and allows the movable ring to slide along the axial direction of the drum.

[0011] In this scheme, the spline connection between the movable ring and the roller ensures both stable circumferential transmission of the roller to the movable ring and axial movement capability of the movable ring, thus providing a basis for the movable ring to participate in the axial reciprocating motion controlled by the guide mechanism.

[0012] Preferably, a connecting block is provided between the movable ring and the spiral frame. The connecting block is fixedly connected to the movable ring and the spiral frame is in a limiting sliding fit, so that the movable ring drives the spiral frame to rotate synchronously and allows the two to be displaced relative to each other along the axial direction.

[0013] In this scheme, through the connection and transmission action of the connecting block, it is possible to ensure that the movable ring drives the spiral frame to rotate synchronously while retaining the axial relative displacement capability between the two. This allows the movable ring and the spiral frame to form a spiral guiding fit and further cooperate with the drive structure and guide mechanism to achieve linkage action.

[0014] Preferably, the driving structure includes a spiral slide plate disposed between the movable ring and the spiral frame, the spiral slide plate being fixedly connected to the connecting block, the spiral slide plate dividing the interior of the spiral frame into two spiral pressure cavities, and the two spiral pressure cavities respectively communicating with two sets of disturbance components disposed on both sides of the spiral frame.

[0015] In this solution, the relative displacement between the movable ring and the spiral frame can be converted into a driving force for the disturbance component by setting up the spiral slide plate and spiral pressure cavity. This allows the disturbance component to operate without the need for a separate external power source, thereby improving the linkage and compactness of the overall structure.

[0016] Preferably, the disturbance component includes a protrusion and at least one pair of disturbance elements, the disturbance elements being oscillatingly disposed on both sides of the protrusion, and the fluid medium in the spiral pressure chamber acting on the transmission element in the protrusion via a connecting channel to drive the disturbance elements to oscillate.

[0017] In this solution, the fluid driving force from the spiral pressure chamber can be converted into the oscillating motion of the disturbance component through the cooperation of the protrusion and the disturbance component, thereby actively disturbing the tea leaves, reducing the accumulation and agglomeration of tea leaves on both sides of the spiral frame, and improving the dispersibility of the tea leaves.

[0018] Preferably, the transmission component includes a slider and an arc-shaped component that guides and cooperates with the slider, the arc-shaped component being connected to the disturbance component in a transmission manner; a spring is provided between the slider and the protrusion, and a torsion spring is provided between the disturbance component and the protrusion.

[0019] In this solution, the combination of slider, arc-shaped component, spring and torsion spring can make the movement of the disturbance component more stable and achieve automatic reset after driving, thereby ensuring that the disturbance component can continuously and repeatedly disturb the tea leaves, improving the reliability and continuity of the disturbance action.

[0020] Preferably, the arc-shaped component has a first protrusion at one end near the slider, and clearance grooves are respectively provided on the two inclined surfaces of the slider. The first protrusion slides in the clearance groove, and a plurality of second protrusions are spaced apart in the clearance groove.

[0021] In this design, the cooperation of the first protrusion, the clearance groove and the second protrusion enables the disturbance component to superimpose small disturbance actions during the main swing process, thereby improving the effect of dispersing and preventing the tea leaves from piling up, making it less likely for the tea leaves to form continuous agglomeration in a local area.

[0022] Preferably, the guiding mechanism includes limiting rings respectively disposed at both ends of the frame, guide rings fixedly disposed within the two limiting rings, and a first push rod and a second push rod respectively connected to both ends of the movable ring and the spiral frame. The guide ring is provided with a guide surface that undulates circumferentially. The first push rod and the second push rod are respectively slidably engaged with the guide surface so that the movable ring and the spiral frame generate axial reciprocating displacement during rotation.

[0023] In this design, the rotational motion of the drum is converted into the axial reciprocating motion of the movable ring and the spiral frame through the cooperation of the limiting ring, the guide ring, the first push rod and the second push rod. This causes the working area inside the drum to change continuously, providing a motion basis for the dynamic covering, guiding and dispersing of tea leaves.

[0024] Preferably, the first push rod and the second push rod are offset in the circumferential direction, and the guide surface protrusions on the two guide rings are staggered, so that the movable ring and the spiral frame form a reverse offset reciprocating motion.

[0025] In this scheme, the staggered cooperation between the first push rod, the second push rod, and the guide ring enables the movable ring and the spiral frame to form a reverse staggered reciprocating motion in the axial direction, thereby causing the guiding area, disturbance area, and cooling area inside the drum to change continuously, further disrupting the fixed accumulation path of the tea leaves and expanding the coverage of the effect at different axial positions.

[0026] Preferably, the cooling structure includes a spiral cavity within the movable ring, annular water bladders at both ends of the movable ring, a large through-hole on the drum, and a small through-hole on the movable ring. The annular water bladders communicate with the spiral cavity, and the small through-holes correspond to and are adjacent to the large through-holes, thereby promoting the circulation of cooling medium between the annular water bladders and the spiral cavity during the axial reciprocating movement of the movable ring, and maintaining ventilation and heat exchange inside and outside the drum. The large through-holes are spaced apart along the axial direction of the drum, and the small through-holes are spaced apart along the axial direction of the movable ring, with the diameter of the large through-holes being larger than the diameter of the small through-holes, so that at least some of the small through-holes communicate with the corresponding large through-holes at different positions during the axial reciprocating movement of the movable ring.

[0027] In this solution, the coordinated operation of the spiral cavity, annular water bladder, large through hole and small through hole can simultaneously achieve heat exchange through cooling medium circulation and heat exchange through ventilation inside and outside the drum, continuously cooling the tea leaves and grinding balls inside the drum, and reducing the problems of tea leaf adhesion, clumping and quality degradation caused by the heat rise of the grinding ball.

[0028] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses an energy-saving ball mill for tea processing. Through the cooperation of a movable ring, a spiral frame, and a disturbance component, the tea leaves and grinding balls can not only tumble with the drum inside the drum, but also move dispersed along the axial direction and be continuously disturbed. This disrupts the concentrated accumulation of tea leaves in local areas, making the contact between the tea leaves and the grinding balls more uniform and improving the ball milling effect.

[0029] The present invention discloses an energy-saving ball mill for tea processing. Through a guiding mechanism, the movable ring and the spiral frame move in opposite directions during rotation, causing the guiding area, disturbance area and action area inside the drum to change continuously. This enables continuous repositioning, stirring and dispersing of the tea leaves, preventing the tea leaves from staying in the same position for a long time and improving the stability of the ball milling process.

[0030] This invention discloses an energy-saving ball mill for tea processing. Through the cooperation of a slider, an arc-shaped component, a spring, and a torsion spring, the movement of the agitator is made more stable, and it automatically resets after being driven. This ensures that the agitator can continuously and reciprocally agitate the tea leaves, improving the reliability and continuity of the agitation action. Furthermore, through the cooperation of the first protrusion, the clearance groove, and the second protrusion, the agitator can superimpose small agitation actions during the main oscillation process, thereby improving the dispersing and anti-agglomeration effect on the tea leaves, making it less likely for the tea leaves to form persistent clusters in certain areas.

[0031] The present invention discloses an energy-saving ball mill for tea processing. Through the combination of large through holes, small through holes, spiral cavity and annular water bag, it can maintain ventilation and heat exchange inside and outside the drum, and realize the circulation of coolant to continuously dissipate heat and cool the tea, grinding balls and the internal space of the drum. This reduces the problems of adhesion, clumping and quality decline of tea caused by collision, compression and friction heating, and improves processing stability. Attached Figure Description

[0039] As attached Figure 1 To be continued Figure 11 As shown: This invention provides an embodiment of an energy-saving ball mill for tea processing. See attached document Figure 1 To be continued Figure 11 It includes a frame 10 and a roller 11 rotatably mounted on the frame 10, and also includes: The movable ring 21 is located inside the roller 11 and is circumferentially linked with the roller 11 and can move axially relative to the roller 11. The spiral frame 19 is located inside the movable ring 21 and is circumferentially driven by the movable ring 21 and can be axially displaced relative to the movable ring 21. Disturbance components 20 are located on both sides of the spiral frame 19; A guiding mechanism is provided between the frame 10 and the movable ring 21 and the spiral frame 19.

[0040] In practice, the drum 11 rotates on the frame 10, driving the movable ring 21 to rotate circumferentially. The movable ring 21 drives the spiral frame 19 to rotate synchronously. Simultaneously, under the action of the guiding mechanism, the movable ring 21 and the spiral frame 19 reciprocate axially, and move in opposite directions. During the relative displacement process, the movable ring 21 and the spiral frame 19 drive the disturbance component 20 through the driving structure to agitate the tea leaves inside the drum 11.

This disrupts the localized accumulation of tea leaves within the drum 11, improves the uniformity of contact between the tea leaves and the grinding balls, reduces agglomeration and heating problems, and enhances the uniformity of tea ball milling.

[0049] Preferred options are shown in the appendix. Figure 5 To be continued Figure 7The cooling structure includes a spiral cavity 22 located within the movable ring 21, annular water bladders 25 located at both ends of the movable ring 21, a large through hole 26 located on the drum 11, and a small through hole 27 located on the movable ring 21. The two ends of the spiral cavity 22 are respectively connected to the interior of the two annular water bladders 25. The small through hole 27 corresponds to and is matched with the large through hole 26 and is located adjacent to the spiral cavity 22, so as to push the cooling medium to circulate between the annular water bladders 25 and the spiral cavity 22 when the movable ring 21 moves axially back and forth, and to maintain ventilation and heat exchange inside and outside the drum 11.

[0050] Preferred options are shown in the appendix. Figure 1 The drive structure also includes an energy-saving motor 13, which is mounted on the frame 10. The output end of the energy-saving motor 13 is provided with a drive wheel 18, and the outer wall of the roller 11 is fitted with a driven wheel 14. The outer wall of the drive wheel 18 and the outer wall of the driven wheel 14 are connected to a number of conveyor belts 15.

[0051] Preferred options are shown in the appendix. Figure 2 To be continued Figure 7 The roller 11 and the movable ring 21 are provided with inlet and outlet 16, and the inlet and outlet 16 are detachably provided with cover plates 17. The interior of the spiral cavity 22 is filled with coolant, and the interior of the spiral pressure cavity 29 is filled with coolant. The roller is provided with inlet and outlet, and the movable ring is provided with clearance openings corresponding to the inlet and outlet. When the movable ring is in the initial loading position, the clearance openings are aligned with the inlet and outlet.

[0052] Specific usage of this invention: The workers first remove the cover plate 17 from the inlet / outlet 16 on the drum 11, opening the inlet / outlet 16. Then, tea leaves and grinding balls are fed into the drum 11 through the inlet / outlet 16. The cover plate 17 is then reinstalled at the inlet / outlet 16 to seal the internal space of the drum 11. After starting the energy-saving motor 13, the motor drives the drive wheel 18 to rotate. The drive wheel 18 then drives the driven wheels 14 to rotate via several conveyor belts 15, thereby driving the drum 11 to rotate on the frame 10. Because the movable ring 21 and the inner wall of the drum 11 are axially slidingly fitted with a spline, the drum 11 can drive the movable ring 21 to rotate synchronously when it rotates. At the same time, the movable ring 21 drives the spiral slide plate 28 to move synchronously through the connecting block 30. With the limiting sliding fit between the connecting block 30 and the spiral frame 19, the movable ring 21 allows the spiral frame 19 to move axially relative to the movable ring 21 while driving the spiral frame 19 to rotate synchronously. Thus, the tea leaves and grinding balls tumble under the combined action of the roller 11, the movable ring 21, and the spiral frame 19, and the tea leaves are gradually ground into finer particles under the impact, compression, and friction of the grinding balls.

[0053] During the ball milling process, the spiral frame 19 located inside the movable ring 21 provides a spiral guide for the tea leaves and grinding balls, causing them to move axially in a dispersed manner as the drum 11 rotates and tumbles. This prevents the tea leaves and grinding balls from concentrating in the same position for extended periods, improving the uniformity of material distribution inside the drum 11. Simultaneously, the agitation components 20 located on both sides of the spiral frame 19 continuously agitate and disperse the tea leaves, redistributing any locally accumulated or initially agglomerated tea leaves and guiding them into the grinding ball's contact area, thereby improving the uniformity of contact between the tea leaves and the grinding balls.

[0054] Furthermore, the first push rod 23 connected to both ends of the movable ring 21 rotates synchronously with the movable ring 21, and the second push rod 32 connected to both ends of the spiral frame 19 rotates synchronously with the spiral frame 19. The first push rod 23 and the second push rod 32 slide in contact with the guide surfaces on the guide rings 24 on both sides. Since the guide surfaces of the guide rings 24 undulate circumferentially, during the continuous rotation of the drum 11, the first push rod 23 and the second push rod 32 change position along the guide surface while rotating around the axis, thereby causing the movable ring 21 and the spiral frame 19 to move axially back and forth. Since the first push rod 23 and the second push rod 32 are offset circumferentially, and the protrusions on the guide surfaces of the two guide rings 24 are staggered, the movable ring 21 and the spiral frame 19 move in opposite directions in the axial direction, that is, when the movable ring 21 moves towards one end of the drum 11, the spiral frame 19 moves towards the other end of the drum 11. This allows the guiding area, disturbance area, and cooling area inside the drum 11 to continuously change, thereby disrupting the fixed accumulation area of ​​tea leaves inside the drum 11, expanding the coverage range of different axial positions, and further improving the uniformity of tea leaf grinding and disturbance.

[0055] Meanwhile, the large through hole 26 on the drum 11 and the small through hole 27 on the movable ring 21 correspond to each other. During the axial reciprocating movement of the movable ring 21, the drum 11 can still maintain a ventilation and heat exchange path inside and outside, which facilitates the dissipation of heat generated during ball milling. Since the small through hole 27 is located near the spiral cavity 22, the gas flowing near the small through hole 27 can also exchange heat with the coolant in the spiral cavity 22, thereby further improving the heat dissipation effect inside the drum 11.

[0056] Furthermore, during the axial reciprocating movement, the movable ring 21 alternately squeezes and releases the annular water bladders 25 at both ends. Utilizing the elastic recovery of the annular water bladders 25, the coolant can flow back and forth between one annular water bladder 25, the spiral cavity 22, and the other annular water bladder 25, thereby promoting the circulation and heat exchange uniformity of the coolant inside the movable ring 21. Consequently, the coolant in the spiral cavity 22 can continuously absorb the heat generated by the tea leaves and grinding balls during the grinding process, reducing the adhesion, clumping, and quality degradation problems caused by the tea leaves heating up due to collision and friction.

[0057] When the movable ring 21 and the spiral frame 19 move in opposite directions, the connecting block 30 drives the spiral slide plate 28 to slide within the spiral frame 19, causing the volume of the two spiral pressure chambers 29 to change alternately. When the spiral slide plate 28 moves towards the inside of the spiral frame 19, the coolant in one of the spiral pressure chambers 29 is pumped through the connecting channel 41 into the cavity 37 of the corresponding set of disturbance components 20. After the coolant enters the cavity 37, it pushes the slider 39 to move. The slider 39, through the guiding engagement with the arc-shaped component 38, pushes the two arc-shaped components 38 to slide away from each other, and causes the disturbance components 34 on both sides to swing more significantly, thereby exerting a stronger stirring and dispersing effect on the tea leaves.

[0058] Furthermore, during the movement of the slider 39, the first protrusion 43 on the arc-shaped member 38 slides within the clearance groove 42 on the slider 39, and sequentially contacts and disengages from the second protrusion 44 spaced apart within the clearance groove 42. Thus, the arc-shaped member 38 generates a small-range pulsating displacement during its overall movement, causing the disturbance member 34 to swing at a large amplitude while simultaneously exhibiting a small-amplitude reciprocating oscillation. After the first protrusion 43 disengages from the second protrusion 44, under the elastic action of the torsion spring 35, the disturbance member 34 can swing towards the reset direction, thereby forming a composite action combining a large oscillation and a small disturbance. This composite disturbance method further prevents the tea leaves from continuously accumulating in local areas, improving the dispersion effect of the tea leaves. Simultaneously, the coolant in the spiral pressure chamber 29 and the chamber 37 can also provide auxiliary cooling and heat dissipation for the area surrounding the disturbance component 20. Furthermore, during the swinging of the disturbance member 34, the telescopic member 36 is elastically stretched to reduce the possibility of tea leaves entering the gap between the disturbance member 34 and the protrusion 33, preventing tea leaves from embedding and causing interference.

[0059] Therefore, through the combined action of the basic ball milling function of the drum 11, the spiral guiding function of the spiral frame 19, the dynamic dispersing function of the disturbance component 20, the reverse staggered reciprocating covering function of the moving ring 21 and the spiral frame 19, and the ventilation and heat exchange and cooling liquid circulation heat dissipation functions of the cooling structure, the tea leaves can be evenly dispersed, prevented from accumulating, dynamically covered and continuously dissipated during the ball milling process, thereby improving the uniformity of tea ball milling and heat dissipation stability, and enabling energy-saving tea processing.
