Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of tea production, and in particular relates to a high-efficiency kneading device capable of improving the quality of tea. Background Art
[0002] Rolling is an important step in tea processing. Rolling can damage the surface cells and cell walls of tea leaves, so that the tea juice overflows and adheres to the surface of the tea leaves. It accelerates the enzymatic oxidation of polyphenol compounds and lays the foundation for the quality of tea leaves. Existing tea rolling machines mostly use a rolling cylinder that moves in a circle above a rolling plate, and a pressure device that extends into the rolling cylinder to make the tea leaves in the rolling cylinder rub on the rolling plate to achieve rolling of the tea leaves;
[0003] However, when the tea leaves are rolled, they are subjected to the combined forces of friction between the rolling cylinder, rolling plate, ribs, and pressure from the pressure cover, which makes it difficult for the tea leaves in the rolling cylinder to be turned over and scattered, thereby forming upper and lower layers of tea leaves in the rolling cylinder. Therefore, under the same rolling time, the rolling degree of the tea leaves in the lower layer is better than that of the tea leaves in the upper layer, resulting in uneven texture of the same batch of tea leaves, affecting the quality of the tea leaves.
[0004] In view of the above problems, the current tea rolling process mostly adopts a layered rolling method, that is: first, the lower layer of tea is rolled, and after rolling, the lower layer of tea is discharged, and then the upper layer of tea is rolled under pressure; although the above method makes up for the uneven texture of the same batch of tea to a certain extent, the effect is still not ideal, such as: due to the manual control of the opening and closing of the material mouth, when the lower layer of tea is poured out, a part of the upper layer of tea with poor rolling degree will also be poured out; for example, due to the layered secondary rolling, the rolling time, rolling pressure, and rolling amount are all variables, and the secondary rolling is also time-consuming and inefficient.
[0005] In view of this, the present invention provides a high-efficiency kneading device capable of improving the quality of tea leaves to solve the above-mentioned problem. Summary of the invention

[0017] As a preferred embodiment of the present invention, an efficient kneading device capable of improving the quality of tea leaves, the upper kneading component comprises: an upper kneading plate, the ribs are connected to the bottom surface of the upper kneading plate, and when the upper kneading plate extends into the kneading cylinder, a relative kneading space is formed between the upper kneading plate and the lower kneading component.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. The present invention installs a rotating upper kneading component on the pressure end of the pressure mechanism on the basis of the existing kneading machine, and cooperates with the lower kneading component, so that when the kneading machine is kneading, the tea leaves in the kneading cylinder will be kneaded at the same time in the upper and lower layers, so that within the same kneading time, the kneading degrees of the upper and lower layers of the tea leaves in the kneading cylinder are relatively consistent. Therefore, compared with the prior art, it can effectively reduce the uneven texture of the tea leaves. At the same time, since there is no need for secondary kneading, the production efficiency of the tea leaves is also improved;
[0020] 2. The present invention bends the ribs on the upper and lower kneading components in opposite directions, and makes the rotation direction of the upper kneading component opposite to the direction of the circular motion of the kneading cylinder, so that when the upper and lower layers of tea leaves in the kneading cylinder are kneaded, due to the different directions of the forces applied, the upper and lower layers of tea leaves are staggered and scattered together during kneading, thereby improving the turning of the tea leaves in the kneading cylinder, making the upper and lower layers of tea leaves evenly mixed during kneading, thereby ensuring the consistency of the kneading degree and improving the kneading uniformity;
[0021] 3. The present invention uses elastic rakes arranged at intervals on the ribs, so that during the rolling process, under the action of the elastic rakes, the tea leaves in the rolling cylinder can be further staggered and scattered, so that the upper and lower layers of tea leaves are fully mixed. While improving the rolling uniformity, the elastic rakes can also make the surface cells of the tea leaves and the cell walls of the tea leaves break faster, and the mixing of tea juice and tea leaves will be better, and the rolling efficiency will be greatly improved;
[0022] 4. Since the ribs of the present invention are arranged in a continuous ring along the center of the axis of the upper kneading component and the lower kneading component, the continuity of the entire rib is better. Compared with the ribs of the prior art, there is no discontinuity, so that the kneading effect on the tea leaves is improved. At the same time, the friction damage to the tea leaves caused by the discontinuous sides of the ribs and the gaps between the discontinuous ribs, which cause the tea leaves to be stuck, are also reduced.
[0023] 5. The present invention enables the lower kneading plate to move longitudinally in the discharge plate under the action of the adjustment mechanism, so that the distance between the ribs of the lower kneading plate and the bottom of the kneading cylinder can be adjusted, so that the kneading force can be adjusted according to the actual tea variety and the kneading force requirements, and the practicality and applicability are better.

[0035] 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.
[0036] The present invention relates to a high-efficiency kneading device capable of improving the quality of tea leaves. Figure 1-Figure 2 As shown, the machine frame 1 includes a frame 1 equipped with a driving member, the frame 1 includes a base, and three vertical supporting feet fixedly connected to the edge of the base at equal intervals, which are used to horizontally support the base. In order to better cooperate with the kneading drum 4 to make circular motion, in this embodiment, the base is preferably in a circular shape, and the driving member is installed on one of the supporting feet, which includes a motor and a reducer, the output end of the motor is connected to the input end of the reducer, and the output end of the reducer vertically extends out of the top of the supporting foot.
[0037] A kneading cylinder 4 with open ends is provided above the frame 1, and the kneading cylinder is longitudinally arranged for filling tea leaves. A lower kneading assembly with one end hinged to the frame 1 is also provided on the other side of the frame 1 relative to the kneading cylinder 4. The lower kneading assembly includes: a discharge tray 2 hinged to the frame 1 and a lower kneading tray 22 arranged in the discharge tray 2. A slidable slider 21 is provided on the bottom surface of the discharge tray 2. The slider 21 is connected to a supporting foot of the frame 1 through a linear drive mechanism 11, such as an electric push rod, a hydraulic push rod, etc. The two ends of the linear drive mechanism 11 are respectively hinged to the slider 21 and a supporting foot of the frame 1, so that a triangular structure is formed between the frame 1, the linear drive mechanism 11 and the discharge tray 2, such as Figure 3 As shown, when the linear drive mechanism 11 is started, the discharge tray 2 can be rotated downward in the horizontal direction to open and close, so as to separate or fit with the base of the frame 1 to facilitate the discharge of tea leaves. In this embodiment, the linear drive mechanism 11 is preferably an electric push rod.
[0038] Furthermore, the top surface of the lower kneading plate 22 is provided with ribs 23 evenly arranged in a ring shape at the center of the axis of the lower kneading plate 22, such as Figure 7As shown, the rib 23 is curved in an arc shape, and its curved end extends downward from the center point to be flush with the edge of the kneading plate 22. Fig. 9 The figure shows the gap 9 between the kneading disk and the feeding port of the kneading machine of the prior art. Since there is an interrupted gap 9 in the middle of the ribs 23, the tea leaves are easily stuck in the gap 9 during kneading, causing waste and damage of the tea leaves. However, due to the continuity of the ribs 23 of the present invention, this situation can be effectively avoided.
[0039] Furthermore, a plurality of grooves 231 are provided at intervals along the bending direction of the top surface of the rib 23, and an elastic rake is provided in each groove 231. Figure 8 As shown, the elastic rake ruler includes: a base 232 movably arranged in a groove 231, a protrusion 233 connected to the surface of the base 232, and a spring 234 arranged between the base 232 and the groove 231. The protrusion 233 can be extended and retracted into the groove 231 by the elasticity of the spring 234 to prevent it from affecting the movement of the rolling cylinder 4 and excessively squeezing the tea leaves. Among them, the protrusion 233 is a pyramid, and its edges and top are chamfered to prevent damage to the rolled tea leaves to ensure the integrity of the tea leaves. At the same time, due to the setting of the protrusion 233, not only can the tea leaves in the rolling process be broken up to achieve uniform rolling of the tea leaves, but also the friction area with the tea leaves is increased, so that the surface cells and inner cell walls of the tea leaves are damaged faster, and the tea juice flowing out can be better mixed with the tea leaves, thereby effectively improving the texture of the tea leaves.
[0040] Furthermore, the lower kneading plate 22 can be driven to move in the discharge tray 2 by an adjustment mechanism disposed between the discharge tray 2 and the lower kneading plate 22, such as Figure 5 As shown, the adjustment mechanism includes: four threaded through holes 24 arranged in a polar axis on the surface of the discharge tray 2, the cross section of the through holes 24 is "T"-shaped, and each adjacent through hole 24 is respectively provided with a movable column 25 sleeved with a spring 26 and a screw rod 27 with a bearing 28 connected to the end, wherein the spring 26 is arranged at the top of the through hole 24, the movable column 25 passes through the through hole 24 and the spring 26 from the bottom of the discharge tray 2 and is fixedly connected to the lower kneading plate 22, and the screw rod 27 is threadedly connected to the through hole 24 from the bottom of the discharge tray 2, and is rotatably connected to the lower kneading plate 22 through the bearing 28; when in use, by rotating the screw rod 27, under the action of the threaded connection between the screw rod 27 and the through hole 24, the screw rod 27 can be moved longitudinally, thereby driving the lower kneading plate 22 to move longitudinally in the discharge tray 2, so as to adjust the distance between the lower kneading plate 22 and the bottom surface of the kneading cylinder 4, and realize the adjustment of the kneading force, so that the kneading force can be adaptively adjusted for different varieties of tea leaves to improve practicality.
[0041] For example, when rolling yellow tea and white tea, the distance between the lower rolling plate 22 and the bottom surface of the rolling cylinder 4 can be increased to reduce the rolling force to meet the rolling requirements of yellow tea and white tea; when rolling black tea and Pu'er tea, a smaller distance needs to be adjusted to increase the rolling force.
[0042] At the same time, in order to facilitate the operator to know the distance between the kneading cylinder 4 and the upper ribs 23 of the lower kneading plate 22, a scale is engraved on the inner wall edge of the discharge plate 2. When the upper surface of the lower kneading plate 22 is flush with the scale, it is the minimum distance between the kneading cylinder 4 and the upper ribs 23 of the lower kneading plate 22.
[0043] It should be particularly noted here that when the discharge plate 2 is in contact with the lower kneading plate 22, the spring 26 is in a compressed state, and then when the lower kneading plate 22 rises, the spring 26 can provide a relatively stable supporting force, making the lower kneading plate 22 more stable when running or kneading.
[0044] A crank transmission mechanism is also provided between the frame 1 and the kneading drum 4. Figure 4 As shown, the crank transmission mechanism includes: an A-frame 3 for embedding a kneading cylinder 4 and three cranks 12 rotatably connected to the end points of the A-frame 3, wherein two cranks 12 are also rotatably connected to the tops of two vertical supporting feet of the frame 1, and one of the cranks 12 is keyed to the output end of the reducer extending from the tops of the supporting feet on the frame 1. When the motor drives the reducer to rotate, the operation of the three cranks 12 can make the A-frame 3 perform circular motion in the horizontal direction, thereby further driving the kneading cylinder 4 embedded in the A-frame 3 to perform circular motion, so as to cooperate with the lower kneading component to realize the kneading operation of the tea leaves in the kneading cylinder 4.
[0045] A pressurizing mechanism is provided on the top surface of the crank transmission mechanism, and an upper kneading component is also installed on the pressurizing end of the pressurizing mechanism. The pressurizing mechanism includes: a KK component 5, a bracket 6 and a motor 7. The KK component 5 is vertically connected to the surface of the herringbone frame 3. The bracket 6 is "L"-shaped, one end of which is connected to the sliding block of the KK component 5 to follow the longitudinal movement of the sliding block, and the other end coincides with the axis of the kneading cylinder 4. The motor 7 is installed on the top of the bracket 6, and its output end passes through the bracket 6 and is connected to the upper kneading component located at the other end of the bracket 6. When the sliding block of the KK component 5 slides, the bracket 6 can drive the upper kneading component to automatically extend into and out of the kneading cylinder 4, thereby realizing fully automatic pressurization of the tea leaves to reduce labor. At the same time, when the motor 7 is running, it drives the upper kneading component to rotate in the opposite direction to the circular motion of the kneading cylinder 4.
[0046] Furthermore, the upper kneading component includes: an upper kneading plate 8, the bottom surface of which is connected to a rib 23 arranged in the same manner as the surface of the lower kneading plate 22, but the difference is that the bending direction of the rib 23 is opposite to the bending direction of the rib 23 on the lower kneading plate 22; when the upper kneading plate 8 is extended into the kneading cylinder 4, relative upper and lower kneading spaces are formed between the upper kneading plate 8 and the lower kneading component to achieve the upper and lower kneading of the tea leaves.
[0047] like Figure 6 As shown, since the ribs 23 of the upper kneading component are in opposite directions to the ribs 23 on the lower kneading component, and the rotation direction of the upper kneading component is opposite to the circular motion of the kneading cylinder 4, the tea leaves in the kneading cylinder 4 will roll, intertwine and break up in the kneading cylinder 4, achieving full mixing and kneading of the tea leaves in real time, thereby ensuring the uniformity and consistency of the tea leaves in one kneading, so as to improve the texture of the tea leaves.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
