Description

Technical Field

[0001] This utility model relates to the field of tea rolling machine technology, specifically to a fully automatic tea rolling machine. Background Technology

[0002] A fully automatic tea rolling machine is an automated tea-making device that can automatically complete the processes of tea feeding, rolling, pressing, loosening and discharging. It uses mechanical force to break and shape tea cells and adsorb aroma substances.

[0003] Existing fully automatic tea rolling machines suffer from excessive impact force due to mechanical transmission design flaws during rolling operations, which is a major cause of tea breakage. Their rolling components are mostly driven by motors to achieve high-speed rotation or reciprocating motion, generating impact force that directly acts on the tea leaves, subjecting them to excessive pressure in a short period and causing excessive cell tissue breakage. Furthermore, they suffer from poor automatic cleaning convenience after use. Their complex internal structure contains numerous narrow gaps and corners between the rolling components and other parts, easily trapping tea juices and debris. Due to the lack of effective automatic cleaning devices, manual cleaning is required after each use, which is time-consuming and difficult to thoroughly clean. Residual impurities breed bacteria, mold, and other microorganisms, threatening the quality and hygiene of subsequent tea production. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a fully automatic tea rolling machine, which solves the problems of existing fully automatic tea rolling machines having large impact force during rolling, which makes the tea leaves easy to break, and the lack of an effective automatic cleaning device after use, which requires manual cleaning, which is time-consuming and incomplete, and leaves residual impurities.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fully automatic tea kneading machine includes a base, a plurality of frames are fixedly connected to the top of the base, a transmission system is fixedly connected to the side wall of one of the frames, a support frame is fixedly connected to the side wall of the frame, kneading discs are fixedly connected between the support frames, and kneading drums are fixedly connected between the frames.

[0008] The kneading drum has brackets fixedly connected to both side walls, and an electric push rod is fixedly connected between the side walls of the brackets at both ends. The other end of the electric push rod is fixedly connected to a support plate through a buffer mechanism.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a fully automatic tea rolling machine.

[0028] This utility model provides, for example Figure 1-5 The fully automatic tea kneading machine shown includes a base 1, a plurality of frames 2 fixedly connected to the top of the base 1, a transmission system 3 fixedly connected to the side wall of one of the frames 2, a support frame 4 fixedly connected to the side wall of the frame 2, kneading discs 5 fixedly connected between the support frames 4, and kneading drums 6 fixedly connected between the frames 2.

[0029] Supports 7 are fixedly connected to both side walls of the kneading drum 6. An electric push rod 8 is fixedly connected between the side walls of the two support supports 7. The other end of the electric push rod 8 is fixedly connected to a support plate 9 via a buffer mechanism. Pressure plates 10 are fixedly connected to both ends of the bottom of the support plate 9. A motor 11 is fixedly connected to the top of the pressure plate 10. A dispersing mechanism is fixedly connected to one end of the motor 11. A ring-shaped cleaning spray plate device 12 is fixedly connected to the top of the pressure plate 10. A booster pump 13 is fixedly connected to one end of the top of the pressure plate 10. A connecting pipe 14 is fixedly connected to the output end of the booster pump 13. The other end of the connecting pipe 14 is fixedly connected to the input end of the ring-shaped cleaning spray plate device 12. The base 1 provides stable support for the entire equipment, ensuring stable operation during the kneading process. The frame 2 serves to install and fix each component. The transmission system 3 provides power for the kneading operation. The system provides power and supports the kneading disc 5 using the support frame 4. The kneading disc 5 works in conjunction with the kneading barrel 6 to achieve the kneading operation of the tea leaves, providing the necessary kneading space for tea processing. The support bracket 7 provides the installation base for the electric push rod 8. The electric push rod 8 drives the support disc 9 and the pressure plate 10 to move up and down, achieving pressure kneading of the tea leaves. The buffer mechanism reduces the impact force during kneading and protects the tea leaves. The dispersion mechanism stirs and disperses the tea leaves, making the kneading more uniform. The annular cleaning spray plate device 12, in conjunction with the booster pump 13 and the connecting pipe 14, can automatically clean the equipment, thereby solving the problems of existing fully automatic tea kneading machines where the impact force during kneading is too great, causing the tea leaves to break easily, and the lack of an effective automatic cleaning device after use, requiring manual cleaning, which is time-consuming, incomplete, and leaves residual impurities.

[0030] To reduce the impact during kneading and minimize tea leaf breakage, such as Figure 1 , 2As shown in Figure 5, the buffer mechanism includes a friction disc 15, a friction sleeve 16, a polyurethane support ring 17, and a hydraulic spring damper 18. The friction disc 15 is fixedly connected to the top of the support disc 9, and the friction sleeve 16 is fixedly connected to one end of the electric push rod 8. The friction sleeve 16 and the friction disc 15 are in frictional engagement. The polyurethane support ring 17 is fixedly connected to the top of the friction disc 15, and the hydraulic spring damper 18 is fixedly connected inside the cavity of the friction sleeve 16. One end of the hydraulic spring damper 18 is fixedly connected to the top of the friction disc 15. The friction between the friction disc 15 and the friction sleeve 16 consumes part of the impact force. The polyurethane support ring 17 buffers the vibration through elastic deformation, and the hydraulic spring damper 18 further absorbs the impact energy. Multiple buffering effectively reduces the impact force during kneading, reduces the tea breakage rate, and ensures the quality of the tea.

[0031] To ensure the tea leaves are thoroughly mixed and dispersed, and to make the kneading more even, such as Figure 2 and 3 As shown, the dispersing mechanism includes a support rod 19, an arc-shaped flexible stirring plate 20, and an inclined flexible stirring plate 21. One end of the motor 11 passes through the top of the pressure plate 10 and is fixedly connected to the support rod 19. Multiple arc-shaped flexible stirring plates 20 are fixedly connected to the upper section of the support rod 19, and inclined flexible stirring plates 21 are fixedly connected to both sides of the lower section of the support rod 19. The motor 11 drives the support rod 19 to rotate, and the arc-shaped flexible stirring plate 20 and the inclined flexible stirring plate 21 rotate accordingly, stirring and dispersing the tea leaves at different positions. The flexible material avoids damaging the tea leaves, ensuring that the tea leaves are subjected to uniform force during the kneading process, thus improving the kneading quality.

[0032] To improve the rolling effect, protect the tea leaves, and reduce friction, such as Figure 1-3 As shown, the kneading barrel 6 is composed of a straight cylindrical section and a conical section fixedly connected. A rubber ring bottom section 22 is fixedly connected to the bottom of the kneading barrel 6. Multiple arc-shaped ribs 23 are fixedly connected to the inner side wall of the kneading barrel 6. A silicone buffer edge 24 is fixedly connected to the outer side wall of the pressure plate 10. Multiple arc-shaped notches 25 are opened on the outer side wall of the silicone buffer edge 24. The arc-shaped ribs 23 are used to increase the friction during kneading and improve the kneading effect. The silicone buffer edge 24 is used to reduce the collision between the pressure plate 10 and the kneading barrel 6. The arc-shaped notches 25 facilitate the flow of tea leaves and further ensure the uniformity of kneading.

[0033] To perform comprehensive automatic cleaning of the equipment and reduce residual impurities, such as Figure 2-4 As shown, the annular cleaning spray plate device 12 is a hollow ring with an arc-shaped surface at the bottom, and the arc-shaped surface has multiple spray holes 26. The arc-shaped surface design allows the spray holes 26 to fully cover the cleaning area. Multiple spray holes 26 spray cleaning water at the same time, which can thoroughly clean the kneading barrel 6 and the pressing plate 10, etc., without the need for manual cleaning, saving time and manpower, and avoiding residual impurities from affecting the quality of tea leaves in the next kneading.

[0034] To prevent tea leaves from sticking together and to improve the wear resistance of parts, such as Figure 1-3 As shown, the surfaces of the kneading barrel 6, pressure plate 10, support rod 19, arc-shaped flexible stirring plate 20, and inclined flexible stirring plate 21 are all provided with a ceramic anti-stick coating. The smooth surface of the ceramic anti-stick coating can effectively prevent tea leaves from sticking to the surface of the components, ensuring smooth kneading, reducing cleaning workload, and the ceramic coating has high wear resistance, which can extend the service life of the components.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
