Description

Technical Field

[0001] This invention relates to the field of tea saponins, specifically a tea saponin extraction device. Background Technology

[0002] Tea saponin is a natural active ingredient extracted from Camellia family plants such as tea seeds and tea cakes. It possesses excellent emulsifying, foaming, and antibacterial properties, has a wide range of applications, and enjoys consistently stable market demand. In the industrial extraction and production of tea saponin, raw material screening pretreatment is a core upstream process. The screening effect directly affects the quality of subsequent purification and processing, as well as the overall extraction efficiency, and is crucial to the quality of the finished product and production capacity. With the continuous upgrading of deep processing technology, the industry has placed higher demands on the precision, uniformity, and production continuity of tea saponin raw material screening.

[0003] The existing screening equipment for tea saponin extraction has a relatively simple structural design, mostly a single-layer screening structure, which can only achieve basic coarse screening operations and is difficult to complete fine classification and screening of coarse and fine materials. The screening accuracy is limited and cannot meet the production requirements of high-quality tea saponin.

[0004] In addition, some equipment lacks an effective material dispersion structure, and raw materials are prone to accumulating and clumping during the production process, resulting in insufficient material screening, easy clogging of the screen surface, poor screening uniformity, and mixed materials, which seriously affect the pretreatment effect. Summary of the Invention

A guide rail is fixedly connected to the frame, and a support wheel is fixedly connected to the bottom of the screening frame, which rests on the guide rail. A drive assembly for driving the screening frame to move linearly along the guide rail is also fixedly connected to the frame. The screening frame is double-layered, with both the upper and lower screening frames inclined. The discharge ports of the upper and lower screening frames are located at the lower end of the inclined direction. A transverse dispersing assembly is slidably connected to the upper screening frame.

[0010] As a further aspect of the present invention: the discharge port of the upper screening box and the discharge port of the lower screening box are located at different positions in the longitudinal projection direction.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please refer to the attached diagram. A tea saponin extraction device consists of two core components: a frame 1 and a screening frame 2. The overall structure is adapted to the industrial production needs of tea saponin raw material screening and pretreatment, and has strong structural stability and is easy to disassemble and maintain.

[0029] To ensure smooth reciprocating screening motion of the screening frame 2, two guide rails 3 are fixedly installed on the upper part of the equipment frame 1. These two guide rails 3 are symmetrically arranged on the left and right sides of the bottom of the screening frame 2, effectively distributing the equipment's operating load and preventing deviation or jamming during long-term operation. Correspondingly, support wheels 4 are fixedly mounted on the bottom of the screening frame 2. The support wheels 4 rest directly on the rail surface of the guide rails 3, allowing for smooth linear sliding along the guide rails 3, significantly reducing frictional resistance during screening and improving equipment operating efficiency. The support wheels 4 are grooved wheels that can be engaged with the guide rails 3 to prevent lateral deviation.

[0030] In addition, the equipment frame 1 is also equipped with a drive component 5, which serves as the power source for the screening frame 2. It is specifically used to drive the entire screening frame 2 to make reciprocating linear motion along the guide rail 3, providing basic power support for raw material screening and adapting to the coarse and fine screening process of raw materials before tea saponin extraction.

[0031] The screening frame 2 of this equipment adopts a double-layer split structure design, consisting of an upper screening structure and a lower screening structure. Both screening structures are installed at an angle, conforming to the production principle of material gravity discharge. The discharge ports of both screening frames 2 are located at the lower end of their respective inclined directions, facilitating the automatic sliding discharge of screened material. Simultaneously, the discharge ports of the upper and lower screening frames 2 are staggered in the longitudinal projection direction and do not overlap, enabling separate collection of coarse and fine materials, avoiding secondary mixing of screened materials, and ensuring the screening accuracy of tea saponin raw materials.

[0032] To address the production issues of raw material accumulation and insufficient screening, a reciprocating transverse dispersion component 6 is installed on the upper screening frame 2. The sliding direction of this transverse dispersion component 6 is perpendicular to the overall movement direction of the screening frame 2 along the guide rail 3. During the overall sliding screening process of the screening frame 2, the transverse dispersion component 6 can simultaneously reciprocate, horizontally flattening and dispersing the tea saponin raw material in the upper screening frame 2, effectively preventing raw material accumulation, ensuring full contact between the raw material and the screen surface, improving the overall screening effect, and adapting to the needs of continuous industrial production.

[0033] As the core power structure, the drive assembly 5 includes a motor 7 fixedly mounted on the equipment frame 1, and a transmission shaft 8 rotatably mounted on the equipment frame 1 via a bearing structure. The motor 7 is the power input component, and its output shaft is coupled to the transmission shaft 8, driving the transmission shaft 8 to rotate continuously. A drive disc 9 is fixedly mounted at the end of the transmission shaft 8, and a drive rod 10 is rotatably connected to the eccentric position of the drive disc 9. The end of the drive rod 10 is rotatably connected to the screening frame 2 body, thus forming an eccentric transmission structure that converts the rotational motion of the motor 7 into the linear reciprocating screening motion of the screening frame 2.

[0034] In terms of power transmission, a drive pulley 11 is fixedly mounted on the output shaft of the motor 7, and a driven pulley 12 is fixedly mounted on the outer side of the transmission shaft 8. A transmission belt 13 is sleeved between the drive pulley 11 and the driven pulley 12. When the equipment is running, the motor 7 drives the drive pulley 11 to rotate, and through the friction transmission of the transmission belt 13, it drives the driven pulley 12 and the transmission shaft 8 to rotate synchronously. This belt drive structure is simple to disassemble and assemble, has low maintenance costs, and can also play an overload buffering role, making it suitable for normal production conditions in the workshop.

[0035] To facilitate on-site adjustment of the screening stroke according to the characteristics of the raw materials, the drive rod 10 adopts a split adjustable structure, mainly composed of a first connecting part 14 and a second connecting part 15. The first connecting part 14 is rotatably connected to the drive disc 9 at an eccentric position, and the second connecting part 15 is rotatably connected to the equipment frame 1. A screw 16 is rotatably mounted on the first connecting part 14, and the other end of the screw 16 is rotatably connected to the second connecting part 15. By rotating the screw 16, the operator can move the first connecting part 14 and the second connecting part 15 closer together or further apart, thereby changing the overall effective length of the drive rod 10 and adjusting the specific position of the reciprocating motion of the screening frame 2 for convenient raw material collection.

[0036] The core working component of the transverse dispersion assembly 6 is the dispersion plate 17. Multiple sets of dispersion teeth 18 are uniformly welded onto the plate body of the dispersion plate 17, which can efficiently disperse the accumulated raw materials. The dispersion plate 17 and the guide rod 19 are fixed as an integral structure. The guide rod 19 is slidably mounted on both sides of the upper screening frame 2 and can slide horizontally back and forth along the upper screening frame 2.

[0037] A turntable 20 is rotatably mounted on the frame of the upper screening frame 2, and a drive column 21 is fitted on the turntable 20. A transmission rod 22 perpendicular to the guide rod 19 is fixedly installed in the middle of the guide rod 19. A long transmission groove 23 is opened at the center of the transmission rod 22, and the drive column 21 is movably embedded in the transmission groove 23. Through the circumferential rotation of the drive column 21, it can drive the transmission rod 22 to perform reciprocating linear motion in conjunction with the transmission groove 23, thereby driving the guide rod 19 and the dispersing plate 17 to slide back and forth synchronously, realizing the lateral dispersion of raw materials. The turntable 20 can be equipped with an independent motor for rotation drive, thereby driving the guide rod 19 to reciprocate during rotation.

[0038] The drive column 21 can be directly and fixedly connected to the turntable 20. Furthermore, to meet production needs with different dispersion amplitudes, the drive column 21 and the turntable 20 adopt a sliding adjustable assembly structure. The drive column 21 can slide radially along the turntable 20, thereby changing the distance between the center of the drive column 21 and the turntable 20. Simultaneously, a locking bolt 24 is threaded on the side of the drive column 21. After position adjustment, tightening the locking bolt 24 will fix the installation position of the drive column 21 and lock the dispersion stroke. The structure is easy to adjust and securely fixed. After debugging, the drive column 21 and the turntable 20 can be locked and fixed to prevent positional displacement during equipment operation and ensure equipment operational stability.

[0039] A dispersing shaft 25 is fixedly connected to the bottom center of the turntable 20. The dispersing shaft 25 is rotatably mounted on the frame of the screening frame 2 and can rotate synchronously with the turntable 20. The bottom of the dispersing shaft 25 passes through the structure of the screening frame 2, and a gear 26 is fixedly installed at its end. Correspondingly, a rack 27 is fixedly mounted on the equipment frame 1, and the gear 26 and the rack 27 are always in a meshing state.

[0040] During actual operation of the equipment, when the screening box 2 slides back and forth in a straight line along the guide rail 3, it will drive the bottom gear 26 to roll along the tooth surface of the fixed rack 27. Through the meshing transmission of the gear and rack, it provides power for the rotation of the turntable 20. There is no need to configure an additional independent drive device, which simplifies the equipment structure, reduces the energy consumption and production cost of the equipment, and is more suitable for mass production.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
