Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a tea processing and kneading device. Background Technology

[0002] Tea, as a widely consumed health beverage, is rich in various beneficial active ingredients such as catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid. These components endow tea with high nutritional and drinking value, and have also driven the continuous development of the tea processing industry. In the standardized processing of tea, fixation, rolling, and drying are three core key processes. Among them, the rolling process directly affects the shaping of the tea leaves, the efficiency of the extraction of internal substances, and the subsequent quality, and the rolling device is the core equipment for realizing this process.

[0003] A search revealed that patent CN221449745U discloses a tea processing kneading device. While this device allows tea leaves to be evenly spread on the filter plate, preventing accumulation from pouring all the tea leaves in, and simultaneously stirs the tea leaves evenly through a uniform mixing rod, ensuring even kneading by the kneading rollers, currently available tea kneading devices still suffer from two critical technical defects that urgently need to be addressed in practical applications, hindering the efficiency and quality of tea processing. Firstly, the existing devices have a significantly insufficient kneading pressure adjustment function, failing to achieve a step-by-step dynamic adjustment from light pressure to medium pressure to heavy pressure based on the tea variety, the tenderness of the fresh leaves, and the processing requirements. This fixed-pressure kneading method easily leads to excessive breakage of tender leaves due to excessive pressure, or insufficient pressure on older leaves, resulting in inadequate kneading.

[0004] On the other hand, during the rolling process, tea leaves inevitably produce a certain amount of tea debris due to mechanical compression and friction. Existing rolling equipment lacks a simultaneous debris handling mechanism; these debris must undergo secondary separation using sieving equipment after the rolling process is complete. This step-by-step "rolling-sieving" operation increases the complexity of tea processing procedures and equipment investment costs, and also extends the overall processing cycle, thus requiring further improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a tea processing and kneading device, which solves the problems mentioned in the background art.

[0006] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0007] A tea processing and kneading device includes a housing, a mounting shaft, and a mounting frame.

[0008] A mounting base is fixedly installed on the bottom end face of the device housing. A screen is fixedly installed inside the device housing. A protrusion is installed on the screen. A first drive motor is installed on the top end face of the device housing. A mounting shaft is installed on the output shaft of the first drive motor. The mounting shaft is located inside the device housing. A second drive motor is installed inside the mounting shaft. A lead screw is installed on the output shaft of the second drive motor.

[0009] Both ends of the mounting shaft are provided with mounting brackets, and guide brackets are welded on the mounting brackets. A rolling roller is provided inside the mounting bracket.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, a feed pipe is provided on the top surface of the device housing, and the feed pipe is connected to the device housing.

[0012] The beneficial effects of adopting the above-mentioned further solutions are:

[0013] By setting up a feed pipe, tea leaves can be dispensed in a specific direction, allowing the tea leaves to be processed to be injected into the outer casing of the device.

[0014] Furthermore, a cover plate is hinged to the side end face of the device housing, and a latch and a locking mechanism are respectively installed on the cover plate and the device housing.

[0015] The beneficial effects of adopting the above-mentioned further solutions are:

[0016] The cover plate creates a closed space inside the device, reducing the splashing of tea leaves during the kneading process. It also allows operators to easily open the device to inspect the internal components and discharge and clean the processed tea leaves. The locking mechanism ensures that the cover plate closes securely during operation, improving operational safety.

[0017] Furthermore, the guide frame is slidably sleeved inside the mounting shaft, and the guide frame is threaded onto the lead screw.

[0018] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] The sliding sleeve of the guide frame and the mounting shaft provides stable guidance for the lifting and lowering of the mounting frame, preventing it from deviating during movement. The threaded connection between the guide frame and the lead screw can convert the rotational motion of the second drive motor into the linear motion of the mounting frame, realizing the adjustment of the distance between the crushing roller and the screen to adapt to the kneading pressure requirements of different teas, thereby performing a step-by-step dynamic adjustment from light pressure to medium pressure to heavy pressure.

[0020] Furthermore, both ends of the rolling roller are equipped with rotating shafts, and the end of the rotating shaft facing away from the rolling roller is sleeved in the mounting frame.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] The sleeve structure between the rotating shaft and the mounting frame allows the pressing roller to rotate. When in contact with the tea leaves, it can roll along with the movement of the tea leaves and the rotation of the mounting shaft, which not only enhances the kneading effect but also reduces the hard friction between the pressing roller and the tea leaves, thus preventing excessive damage to the tea leaves.

[0023] Furthermore, a rotating block is welded to the bottom end face of the guide frame, and when the rotating block rotates, it drives the screen to vibrate through the protrusion.

[0024] The beneficial effects of adopting the above-mentioned further solutions are:

[0025] As the rotating block rotates with the guide frame, it intermittently contacts and collides with the protrusions on the screen, causing the screen to vibrate. This vibration enables the tea leaves generated during the kneading process to quickly pass through the mesh of the screen and be separated out, achieving simultaneous kneading and sieving, improving the quality of tea processing and subsequent cleaning efficiency.

[0026] This utility model provides a tea processing and kneading device. It has the following beneficial effects:

[0027] This device drives the lead screw to rotate via a second drive motor. Combined with the threaded connection between the guide frame and the lead screw, and the sliding sleeve structure between the guide frame and the mounting shaft, it can control the lifting and lowering of the mounting frame and the grinding roller, and adjust the distance between the grinding roller and the screen. This design allows for stepped dynamic pressure adjustment from light pressure to medium pressure to heavy pressure, based on different processing requirements of tea varieties (such as green tea and black tea) and the tenderness of fresh leaves (such as buds and one bud with two leaves). This effectively avoids the problems of excessive crushing of tender leaves and insufficient kneading of older leaves, significantly improving the uniformity of the finished tea product's appearance and the stability of its internal quality.

[0028] The device innovatively incorporates protrusions on the screen and welds rotating blocks to the bottom of the guide frame. When the first drive motor rotates the mounting shaft and guide frame, the rotating blocks intermittently collide with the protrusions, thereby driving the screen to vibrate continuously. This vibration can separate tea leaves generated during the kneading process through the screen mesh in real time, directly achieving integrated "kneading-sieving" operation. Compared to the traditional step-by-step method that requires additional sieving after kneading, this design not only eliminates the separate sieving process, reducing equipment investment and processing cycle, but also avoids quality contamination caused by prolonged mixing of tea leaves and whole tea leaves, further improving the cleanliness of tea processing and overall production efficiency.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1

[0040] A tea processing and kneading device includes a housing 2, a mounting shaft 4, and a mounting frame 5.

[0041] A mounting base 1 is fixedly installed on the bottom end face of the device housing 2. A screen 6 is fixedly installed inside the device housing 2. A protrusion 601 is installed on the screen 6. A first drive motor 3 is installed on the top end face of the device housing 2. A mounting shaft 4 is installed on the output shaft of the first drive motor 3. The mounting shaft 4 is located inside the device housing 2. A second drive motor 401 is installed inside the mounting shaft 4. A lead screw 402 is installed on the output shaft of the second drive motor 401.

[0042] Mounting shaft 4 is provided with mounting brackets 5 at both ends. Guide brackets 502 are welded on the mounting brackets 5, and rolling rollers 501 are provided inside the mounting brackets 5.

[0043] The top surface of the device housing 2 is provided with a feed pipe 202, which is connected to the device housing 2. By setting the feed pipe 202, the tea leaves can be directionally fed into the device housing 2.

[0044] A cover plate 201 is installed on the side end face of the device housing 2 via a hinge. The cover plate 201 and the device housing 2 are respectively equipped with a latch and a locking mechanism. The cover plate 201 can form a closed space inside the device housing 2, reducing the splashing of tea leaves during the kneading process. At the same time, it is convenient for operators to open the device to inspect the internal components and discharge and clean the processed tea leaves. The cooperation of the latch and the locking mechanism can ensure that the cover plate 201 is firmly closed when the equipment is running, improving operational safety.

[0045] The guide frame 502 is slidably sleeved inside the mounting shaft 4. The guide frame 502 is threaded onto the lead screw 402. The sliding sleeve connection between the guide frame 502 and the mounting shaft 4 provides stable guidance for the lifting and lowering of the mounting frame 5, preventing it from deviating during movement. The threaded connection between the guide frame 502 and the lead screw 402 can convert the rotational motion of the second drive motor 401 into the linear motion of the mounting frame 5, realizing the adjustment of the distance between the pressing roller 501 and the screen 6 to adapt to the kneading pressure requirements of different teas, thereby performing a step-by-step dynamic adjustment from light pressure to medium pressure to heavy pressure.

[0046] Both ends of the pressing roller 501 are equipped with rotating shafts, and the end of the rotating shaft facing away from the pressing roller 501 is sleeved in the mounting frame 5. The sleeve structure between the rotating shaft and the mounting frame 5 allows the pressing roller 501 to rotate. When in contact with tea leaves, it can roll with the movement of tea leaves and the rotation of the mounting shaft 4, which not only enhances the kneading effect but also reduces the hard friction between the pressing roller 501 and the tea leaves, thus avoiding excessive damage to the tea leaves.

[0047] Example 2

[0048] To separate tea leaves from debris through vibration during the rolling process, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0049] A rotating block 503 is welded to the bottom end face of the guide frame 502. When the rotating block 503 rotates, it drives the screen 6 to vibrate through the protrusion 601. When the rotating block 503 rotates with the guide frame 502, it will intermittently contact and collide with the protrusion 601 on the screen 6, thereby causing the screen 6 to vibrate. This vibration can promote the rapid separation of tea leaves generated during the kneading process through the mesh of the screen 6, so as to realize the simultaneous kneading and screening, improve the tea processing quality and subsequent cleaning efficiency.

[0050] Furthermore, both the first drive motor 3 and the second drive motor 401 of the device can be powered and controlled by external power supplies and external control switches, and both the first drive motor 3 and the second drive motor 401 can be connected to a speed reducer for use. The power supply and control principles and circuit connection methods of the external power supply and external control switches are common functional module designs, which are common knowledge in the fields of electrical automation control and mechanical equipment. The relevant technologies are widely used and the principles are clear, so there is no need to elaborate further.

[0051] Working principle:

[0052] Preliminary preparations and tea application:

[0053] The operator first uses the latches and locking structures on the two sides of the device casing to ensure that the cover plate 201 is in a stable closed state, so that the inside of the device forms a closed space and prevents tea leaves from splashing during subsequent operations.

[0054] The tea leaves to be kneaded (distinguished by variety and age) are fed into the device through the feed pipe 202 on the top surface of the outer shell 2. The tea leaves enter the inner shell 2 of the device directly through the feed pipe 202 and fall onto the surface of the screen 6, thus completing the material preparation before processing.

[0055] Kneading pressure preset adjustment:

[0056] Start the second drive motor 401 installed inside the mounting shaft 4, and the output shaft of the second drive motor 401 drives the lead screw 402 to rotate.

[0057] Since the guide frame 502 welded on the mounting bracket 5 is threaded onto the lead screw 402, and the guide frame 502 is simultaneously slidably sleeved in the mounting shaft 4, the rotational motion of the lead screw 402 is converted into the linear lifting and lowering motion of the guide frame 502 along the mounting shaft 4.

[0058] The guide frame 502 drives the mounting frame 5 and the rolling roller 501 inside the mounting frame 5 to rise and fall synchronously. By adjusting the distance between the rolling roller 501 and the screen 6, the required initial kneading pressure is preset (select the initial value of light pressure, medium pressure or heavy pressure according to the characteristics of tea). After the pressure adjustment is completed, the second drive motor 401 is turned off.

[0059] Kneading operation and dynamic pressure adjustment:

[0060] The first drive motor 3 is mounted on the top surface of the starting device housing 2. The output shaft of the first drive motor 3 drives the mounting shaft 4 to rotate inside the device housing 2.

[0061] When the mounting shaft 4 rotates, it synchronously drives the mounting frames 5 at both ends and the rolling roller 501 to make a circular motion. The rolling roller 501 rotates flexibly in the mounting frame 5 through the rotating shafts at both ends, and comes into contact with the tea leaves on the surface of the screen 6 to produce a rolling and rolling action, thus officially starting the kneading operation.

[0062] If it is necessary to adjust the pressure according to the rolling progress (to achieve a step-by-step change from light pressure to medium pressure to heavy pressure), the second drive motor 401 can be restarted to repeat the process of "rotating the lead screw 402 → lifting the guide frame 502 → adjusting the spacing of the rolling roller 501" to dynamically adjust the rolling pressure and ensure that the tea rolling effect at different stages meets the standards.

[0063] During the kneading process, debris is processed simultaneously:

[0064] While the first drive motor 3 drives the mounting shaft 4 to rotate, the rotating block 503 welded to the bottom end of the guide frame 502 moves in a circular motion synchronously with the guide frame 502.

[0065] When the rotating block 503 moves to the surface of the screen 6, it will intermittently collide with the protrusion 601 installed on the screen 6. The impact force generated by the collision drives the screen 6 to vibrate continuously.

[0066] Tea leaves fragments generated during the kneading process are quickly separated from whole tea leaves by passing through the mesh of the screen 6 under the vibration of the screen 6, thus achieving simultaneous kneading and sieving and avoiding the accumulation of fragments that affect the quality of the tea.

[0067] Completion of assignment and follow-up operations:

[0068] After the kneading operation is completed, first turn off the first drive motor 3. After the device has completely stopped running, open the cover plate 201 through the hinge structure between the cover plate 201 and the outer shell 2 of the device.

[0069] Operators can directly remove the whole tea leaves that have been kneaded from the screen 6 from inside the outer casing 2 of the device, and at the same time clean up the tea leaf debris collected below the screen 6.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
