Description

Technical Field

[0001] This application relates to the technical field of tea rolling, and specifically discloses a rolling device for tea processing. Background Art

[0002] Tea rolling is one of the tea-making processes, and most tea-making processes include this process;

[0003] Rolling the fresh leaves that have been softened by fixation or withering into shapes such as strips, needles, granules, and slices by hand or machine is called rolling. Rolling can be understood as two actions. One is rolling, that is, forming curly strip-like shapes of tea leaves through external forces; the other is twisting, which can break the tea cells, squeeze out the tea juice, make the tea juice adhere to the surface of the tea leaves, increase the viscosity, and is conducive to the formation of the tea leaf appearance;

[0004] Tea rolling can shape the appearance of tea leaves: making the tea leaves form various beautiful shapes that are tight and curved and meet the requirements of specific tea categories. For example, the tight and curved appearance of oolong tea is formed through rolling;

[0005] Promote the transformation of internal quality: After the cells are broken, the tea juice overflows and adheres to the leaf surface, increasing the surface viscosity of the tea leaves, facilitating the oxidation, polymerization and other reactions of the substances contained in the tea leaves during subsequent processing, and playing an important role in the formation of the color, aroma and taste qualities of the tea. At the same time, rolling can also make the effective components in the tea leaves dissolve better, improving the concentration and taste of the tea soup;

[0006] Chinese Patent CN109303127A discloses a rolling device for tea processing, including a machine shell, a first rolling device and a second rolling device fixed inside the machine shell. The first rolling device includes a first motor, a pressing block fixedly connected to the output shaft of the first motor, and a rolling pot fixed in the machine shell through a second support plate. The pressing block is provided with a first convex block on the surface in contact with the rolling pot, and a first strainer is provided at the bottom of the rolling pot. The second rolling device includes a second motor fixed on a motor mounting frame, a rolling wheel fixedly connected to the output shaft of the second motor, and a rolling barrel sleeved outside the rolling wheel. A second strainer is provided at the bottom of the rolling barrel. A feed hopper is provided at the top of the rolling barrel directly below the first strainer. One end of the rolling barrel away from the second motor is fixed on the machine shell through a third support plate. A collection barrel is placed below the rolling barrel. The present invention can roll the tea leaves repeatedly, with uniform rolling, high rolling efficiency and good effect;

[0007] Specifically:

[0008] The rolling pan is filled with tea leaves. The first rolling device performs the first rolling operation, that is, the first motor drives the pressing block to rotate in the rolling pan, and the gravity and frictional forces during rotation of the pressing block are used to roll the tea leaves. The first convex blocks on the pressing block can further enhance the rolling effect. The tea leaves that reach a certain standard after rolling leak from the first strainer at the bottom of the rolling pan into the rolling barrel of the second rolling device. The second motor drives the rolling wheel to rotate, squeezing and rubbing the tea leaves between the rolling wheel and the rolling barrel, thereby further achieving the rolling effect. The qualified tea leaves leak out from the second strainer and are collected in the collection barrel;

[0009] Currently, the existing problems are as follows:

[0010] 1. The rolling path is fixed, which will lead to insufficient rolling because the tea leaves not on the rolling path cannot be rolled, and affected by the rotational centrifugal force, the tea leaves will gradually move towards the outer circle, which will further exacerbate the impact of insufficient rolling;

[0011] 2. The rolling function cannot be precisely controlled. For tea leaves, rolling means twisting and turning. After twisting and turning, the shape of the tea leaves changes. The contact area between the initial tea leaves and the rolling wheel is inconsistent with the contact area between the tea leaves with the changed shape after twisting and turning and the rolling wheel. This will lead to the inability to precisely control the rolling function, thereby affecting the quality of the tea leaves.

[0012] The present invention provides a rolling device for tea processing to solve the above problems. Summary of the Invention

[0013] The purpose of the present invention is to solve the problems that the traditional rolling device for tea processing cannot roll sufficiently and the rolling function cannot be precisely controlled, which in turn leads to the problem that the quality of tea processing cannot reach a high level.

[0014] To achieve the above purpose, the present invention provides the following basic solution:

[0015] A rolling device for tea processing, comprising a rolling pan, a collection cylinder detachably connected to the bottom of the rolling pan, a tea leaf reflux assembly based on the collection cylinder, an annular groove opened at the bottom of the rolling pan for allowing tea leaves to enter the collection cylinder, an installation cylinder based on the rolling pan, a bearing plate rotatably connected inside the rolling pan, a feed pipe and a re-entry pipe penetrating and installed on the installation cylinder, and a lifting and self-rotating assembly arranged on the installation cylinder. The output end of the lifting and self-rotating assembly is connected with a rolling rod, and a rolling gap is left between the rolling rod and the bearing plate;

[0016] The feed pipe is used for initially putting tea leaves into the bearing plate, and the re-entry pipe is used in cooperation with the tea leaf reflux assembly for putting tea leaves back into the bearing plate after reflux;

[0017] The outer periphery of the rolling rod is provided with a precise distance adjustment component, and the precise distance adjustment component can change the rolling gap between the rolling rod and the bearing plate.

[0018] Furthermore, several support frames are fixedly connected around the rolling plate, support columns are installed on the support frames, and rubber anti-slip pads are fixedly connected to the free ends of the support columns.

[0019] Furthermore, threaded grooves are formed on the bottom surface of the rolling plate. The size of the annular groove is smaller than the internal size of the collection cylinder. External threads are provided on the outer periphery of the collection cylinder, and the rolling plate and the collection cylinder are connected by threaded connection.

[0020] Furthermore, a motor is arranged at the bottom of the rolling plate. The output end of the motor passes through the rolling plate and is rotationally connected to the bearing plate. The rotation direction of the bearing plate is opposite to that of the rolling rod. The upper end surface of the bearing plate includes a bearing surface and an inclined surface. The bearing surface is used for bearing tea leaves. The bearing surface and the inclined surface are integrally formed. The inclined direction of the inclined surface faces the annular groove, and a stabilizing frame is arranged in the annular groove.

[0021] Furthermore, it enters the collection cylinder through the annular groove and is acted on by the tea leaf reflux component. The tea leaf reflux component includes several mounting holes formed around the collection cylinder, conduits mounted based on the mounting holes, a connecting pipe for aggregating the conduits, a storage pipe, and a negative pressure fan. The connecting pipe is installed in the mounting cylinder. One end of the connecting pipe is communicated with the conduit, and the other end of the connecting pipe is communicated with the re-entry pipe. The top of the re-entry pipe is connected to the storage pipe. A fan pipe is arranged at the free end of the storage pipe. The fan pipe is connected to the negative pressure fan. An electric control switch valve is arranged at the inner bottom of the re-entry pipe. When the negative pressure fan starts, the electric control switch valve is closed. On the contrary, the electric control switch valve is opened.

[0022] Furthermore, the lifting and self-rotating component includes a mounting groove formed in the mounting cylinder, a motor arranged in the mounting groove, and a cylinder arranged at the top of the mounting cylinder. The extending end of the cylinder is connected to the motor housing. The output shaft of the motor passes through the mounting cylinder and is connected to the rolling rod. The rotation direction of the motor is opposite to that of the motor.

[0023] Furthermore, the acting range of the rolling rod is equal to the size of the bearing surface. A connecting rod is fixedly connected to the output shaft of the motor. The rolling rod is connected to the connecting rod. A precise distance adjustment component is arranged on the outer periphery of the rolling rod. The precise distance adjustment component includes an inner frame fixedly connected to the outer periphery of the rolling rod, support plates uniformly arranged on the inner frame, and movable plates arranged on adjacent support plates. A gas generator is arranged on the support plate. The gas generator, the movable plate, and the support plate form a number of accommodation cavities. An inflatable airbag is arranged in the accommodation cavity. The gas generator is provided with a plurality of air outlets corresponding to the inflatable airbags. The air outlets are connected to their respective inflatable airbags. The expansion end of the inflatable airbag is fixedly connected to the movable plate. One end of the movable plate away from the inflatable airbag is fixedly connected to the mounting block. Arc-shaped plates are fixedly connected to the free ends of the mounting blocks.

[0024] Furthermore, a number of bearing frames are fixedly connected to the bottom of the mounting cylinder. The free ends of the bearing frames are fixedly connected to the surface of the rolling disk.

[0025] Furthermore, a thin film pressure sensor is arranged on the outer periphery of the arc-shaped plate. It also includes a controller. The controller is electrically connected to the motor and the gas generator. An electromagnetic switch valve is arranged on the inflatable airbag. The electromagnetic switch is electrically connected to the controller.

[0026] The principle and effect of this solution are as follows:

[0027] 1. Compared with the prior art, this device can achieve the same degree of rolling as manual rolling. The reason why the quality of manual rolling is higher is that manual rolling can achieve comprehensive rolling, and this device can also achieve it. Traditional rolling machines cannot achieve it because, due to the fixed rolling path, usually rotary rolling, the centrifugal force generated by rotary rolling causes the tea leaves to approach the end of the rolling rod under the action of centrifugal force. At this time, the tea leaves cannot be rolled and will naturally mix with the already rolled tea leaves, resulting in a naturally low quality of tea leaf rolling. Of course, if the inner diameter of the rolling rod is the same as that of the rolling cylinder, the above problem also exists. However, manual rolling can avoid this problem because the position of the tea leaves can be artificially changed. Based on this, this device designs a new rolling device that does not require human power and can avoid the influence of the centrifugal force brought by the rolling rod, thereby achieving comprehensive rolling.

[0028] 2. Compared with the prior art, this invention still takes rotary rolling as the core of rolling. However, a slot is directly opened on the outer side of the bottom of the rolling cylinder. Since the tea leaves will approach the end of the rolling rod under the action of centrifugal force, the tea leaves in this part are separated from the tea leaves being rolled through the slot. Then, based on the slot position, a tea leaf backflow component is designed. By using the tea leaf backflow component, the tea leaves that have not been fully rolled can re-enter the feed pipe and be rolled by the rolling rod again. Through repeated cycles, comprehensive rolling of the tea leaves is achieved, thereby improving the rolling quality.

[0029] 3. Compared with the prior art, since the tea leaf reflux component enables the tea leaves that have not been fully kneaded to re-enter the feed pipe, there are some tea leaves that are kneaded multiple times at this time. To ensure that all tea leaves have the same degree of kneading, the kneading rod is designed not to contact the bottom of the kneading plate, so that there is a certain distance between the kneading rod and the bottom of the kneading plate. Since the tea leaves themselves have a certain volume, kneading is achieved by having a certain distance between the kneading rod and the bottom of the kneading plate. When the tea leaves can no longer contact the kneading rod, it means that the kneading of the tea leaves is completed.

[0030] 4. Compared with the prior art, in order to improve the kneading quality, the kneading process is designed in segments, that is, the distance between the kneading rod and the bottom of the kneading plate is made adjustable. After the distance is made adjustable, segmented kneading is achieved.

[0031] 5. Compared with the prior art, regarding kneading: one is "rou" (knead), that is, by applying an external force to make the tea leaves form curly strip shapes; the other is "nian" (twist), which can break the tea leaf cells, squeeze out the tea juice, and make the tea juice adhere to the surface of the tea leaves, increasing the viscosity and facilitating the formation of the tea leaf shape. This shows that kneading is an action of the device to curl and squeeze the tea leaves, which will inevitably bring about a change in the volume of the tea leaves. When the volume of the tea leaves changes, if the distance between the kneading rod and the bottom of the kneading plate cannot be adjusted, the kneading degree is a single degree, which cannot meet the improvement of kneading quality. For this reason, this device is provided with a precise distance adjustment component. Compared with the traditional cylinder adjustment, the precise distance adjustment component has outstanding advantages in distance control. First, the cylinder adjustment is too large, and since the tea leaves are of small volume, the cylinder adjustment is not applicable. Second, the adjustment adopted by this device is pressure-contact type adjustment, that is, when all the contact pressure disappears, it means that the single-degree kneading has ended and it is necessary to enter the kneading of the next degree. Using the disappearance of pressure as the start signal, the distance between the kneading rod and the bottom of the kneading plate is adjusted smaller through the precise distance adjustment component. When the pressure reappears, the adjustment ends. At this point, when the pressure disappears again, it means that the kneading of this degree has ended. Therefore, this device fully utilizes the pressure generation signal, the pressure disappearance signal, the gas generator, and the inflatable airbag in the precise distance adjustment component, and uses the inflation of the inflatable airbag to achieve the reduction of the distance between the kneading rod and the bottom of the kneading plate. This mode is more delicate and precise compared with cylinder adjustment, and does not require manual adjustment of the cylinder. Only by presetting the thresholds of multiple segments of pressure can the segmented multi-stage kneading of the tea leaves be achieved. By the segmented multi-stage kneading of the tea leaves, the kneading is improved. Furthermore, this device solves the problems that the traditional kneading equipment for tea processing cannot fully knead and the twisting function cannot be precisely controlled, resulting in the tea processing quality not reaching a high level.

[0041] Embodiments are as Figures 1-6 shown:

[0042] A rolling and kneading device for tea processing, comprising a rolling and kneading plate 14, a collecting cylinder 1 detachably connected to the bottom of the rolling and kneading plate 14, a tea reflux assembly arranged based on the collecting cylinder 1, an annular groove 20 opened at the bottom of the rolling and kneading plate 14 for allowing tea to enter the collecting cylinder 1, a mounting cylinder 12 arranged based on the rolling and kneading plate 14, a bearing plate 18 rotatably connected inside the rolling and kneading plate 14, a feed pipe 10 and a re-entry pipe 7 penetrating through the mounting cylinder 12, and a lifting and self-rotating assembly arranged on the mounting cylinder 12. The output end of the lifting and self-rotating assembly is connected with a rolling and kneading rod 1701, and a rolling and kneading gap is left between the rolling and kneading rod 1701 and the bearing plate 18; the feed pipe 10 is used for initially feeding tea into the bearing plate 18, and the re-entry pipe 7 is used in cooperation with the tea reflux assembly for feeding refluxed tea into the bearing plate 18; a precise distance adjusting assembly 17 is arranged on the outer periphery of the rolling and kneading rod 1701, and the precise distance adjusting assembly 17 can change the rolling and kneading gap between the rolling and kneading rod 1701 and the bearing plate 18.

[0043] In terms of the overall structure:

[0044] A number of support frames 15 are fixedly connected around the rolling and kneading plate 14. A support column 4 is installed on the support frame 15, and a rubber anti-slip pad 5 is fixedly connected to the free end of the support column 4. A number of bearing frames 13 are fixedly connected to the bottom of the mounting cylinder 12, and the free ends of the bearing frames 13 are fixedly connected to the surface of the rolling and kneading plate 14.

[0045] Regarding the detachable connection between the rolling and kneading plate 14 and the collecting cylinder 1:

[0046] A threaded groove is opened on the bottom surface of the rolling and kneading plate 14. The size of the annular groove 20 is smaller than the internal size of the collecting cylinder 1. An external thread 3 is arranged on the outer periphery of the collecting cylinder 1. The rolling and kneading plate 14 and the collecting cylinder 1 are connected by threaded connection.

[0047] The size of the annular groove 20 is smaller than the internal size of the collecting cylinder 1, so that the tea falling into the annular groove 20 directly enters the collecting cylinder 1 for collection;

[0048] A motor is arranged at the bottom of the rolling and kneading plate 14. The output end of the motor passes through the rolling and kneading plate 14 and is rotatably connected to the bearing plate 18. The rotating direction of the bearing plate 18 is opposite to that of the rolling and kneading rod 1701. The upper end surface of the bearing plate 18 includes a bearing surface and an inclined surface 19. The bearing surface is used for bearing tea, the bearing surface and the inclined surface 19 are integrally formed, the inclined direction of the inclined surface 19 faces the annular groove 20, and a stabilizing frame 21 is arranged in the annular groove 20.

[0049] The rotation of the bearing plate 18 can cooperate with the rotation of the rolling and kneading rod 1701 to accelerate rolling and kneading. The tea falls on the bearing surface. Due to the centrifugal force, the tea will approach the end of the rolling and kneading rod 1701. This part of the tea is separated from the tea being rolled and kneaded through the annular groove 20, and at this time the tea enters the collecting cylinder 1;

[0050] Then, it enters the collection cylinder 1 through the annular groove 20 and is affected by the tea leaf reflux assembly. The tea leaf reflux assembly includes a number of mounting holes opened around the collection cylinder 1, a conduit 2 mounted based on the mounting holes, a connecting pipe 6 for aggregating the conduits 2, a storage pipe 8, and a negative pressure fan. The connecting pipe 6 is installed in the mounting cylinder 12. One end of the connecting pipe 6 is connected to the conduit 2, and the other end of the connecting pipe 6 is connected to the re-entry pipe 7. The top of the re-entry pipe 7 is connected to the storage pipe 8. A fan pipe 9 is provided at the free end of the storage pipe 8, and the fan pipe 9 is connected to the negative pressure fan. An electric control switch valve 24 is provided at the inner bottom of the re-entry pipe 7. When the negative pressure fan is started, the electric control switch valve 24 is closed. Conversely, the electric control switch valve 24 is opened.

[0051] When the negative pressure fan is started, negative pressure acts on the connecting pipe 6 and then on the conduit 2, and then the tea leaves inside the collection cylinder 1 are sucked in. The tea leaves enter the storage pipe 8 through the re-entry pipe 7. Then, the negative pressure fan is turned off, and the electric control switch valve 24 is opened. The tea leaves affected by the leaf reflux assembly fall on the bearing plate 18 through the re-entry pipe 7 and are kneaded again by the kneading rod 1701.

[0052] The lifting and self-rotating assembly includes a mounting groove opened on the mounting cylinder 12, a motor 23 provided in the mounting groove, and a cylinder 11 provided at the top of the mounting cylinder 12. The extending end of the cylinder 11 is connected to the outer shell of the motor 23. The output shaft of the motor 23 passes through the mounting cylinder 12 and is connected to the kneading rod 1701. The rotation direction of the motor 23 is opposite to that of the motor.

[0053] The distance between the kneading rod 1701 and the receiving plate is changed by the cylinder 11, and the motor 23 is used to rotate the kneading rod 1701.

[0054] Specifically:

[0055] The working range of the rolling rod 1701 is equal to the size of the bearing surface. Specifically: a connecting rod 16 is fixedly connected to the output shaft of the motor 23, the rolling rod 1701 is connected to the connecting rod 16, a precise distance adjustment component 17 is arranged on the outer periphery of the rolling rod 1701, the precise distance adjustment component 17 includes an inner frame 1702 fixedly connected to the outer periphery of the rolling rod 1701, support plates 1703 uniformly arranged on the inner frame 1702, and movable plates 1706 arranged on adjacent support plates 1703. A gas generator 1704 is arranged on the support plate 1703. The gas generator 1704, the movable plate 1706 and the support plate 1703 form a number of accommodation cavities, and inflation air bags 1705 are arranged in the accommodation cavities. The gas generator 1704 is provided with a plurality of air outlets corresponding to the inflation air bags 1705, the air outlets are connected to their respective inflation air bags 1705, the expansion ends of the inflation air bags 1705 are fixedly connected to the movable plate 1706, and one end of the movable plate 1706 away from the inflation air bag 1705 is fixedly connected to the mounting block 1707. Arc-shaped plates 1708 are fixedly connected to the free ends of the mounting blocks 1707.

[0056] A thin film pressure sensor 1709 is arranged on the outer periphery of the arc-shaped plate 1708. It also includes a controller, the controller is electrically connected to the motor 23 and the gas generator 1704, an electromagnetic switching valve is arranged on the inflation air bag 1705, and the electromagnetic switch is electrically connected to the controller.

[0057] Specifically: by the inflation or deflation of the inflation air bag 1705, the size of the arc-shaped plate 1708 is changed, and through the change of the size, different degrees of rolling are realized.

[0058] This device adopts pressure contact type adjustment, that is, when the contact pressure completely disappears, it means that the rolling of a single degree has ended and it is necessary to enter the rolling of the next degree. Using the disappearance of pressure as the start signal, the distance between the rolling rod 1701 and the bottom of the rolling disc 14 is adjusted smaller through the precise distance adjustment component 17, and when the pressure reappears, the adjustment ends. At this point, when the pressure disappears again, it means that the rolling of this degree has ended. Therefore, this device makes full use of the pressure generation signal, the pressure disappearance signal, the gas generator 1704 and the inflation air bag 1705 in the precise distance adjustment component 17, and realizes the reduction of the distance between the rolling rod 1701 and the bottom of the rolling disc 14 by the inflation of the inflation air bag 1705. Compared with the adjustment of the cylinder 11, this mode is more delicate and accurate, and does not require manual adjustment of the cylinder 11. Only by presetting the thresholds of multiple segments of pressure can the segmented multi-stage rolling of tea leaves be realized, and the rolling is improved through the segmented multi-stage rolling of tea leaves.

[0059] This device solves the problems that the traditional rolling equipment for tea processing cannot fully roll and the rolling function cannot be accurately controlled, resulting in the tea processing quality not reaching a high level.

Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
