Description

Technical Field

[0001] The invention relates to the technical field of tea processing, in particular to an automatic tea leaf withering and stripping machine and a tea leaf withering and stripping method. Background Art

[0002] With the rapid economic and social development of my country, tea consumption is constantly increasing. According to statistics from the China Tea Circulation Association, China's average annual production of the six major tea categories is 2,986 kt, with an output value of 262.3 billion yuan. Of this, green tea production accounts for 1,842.7 kt, or 61% of the total. Faced with this enormous demand for tea, manual tea processing alone is insufficient to meet production requirements. Therefore, the promotion of mechanized tea processing has become a solution to increase tea production.

[0003] The process of withering and straightening tea leaves plays a crucial role in tea production and processing, directly impacting their appearance and quality. Withering involves applying heat to the tea leaves using a higher external temperature, thereby destroying the oxidase activity within the fresh leaves. Straightening, on the other hand, involves shaping the tea leaves into strips, which improves their color, aroma, and other qualities.

[0004] At present, the withering and stripping of tea leaves are almost all replaced by withering and stripping machines instead of manual labor. The use of mechanical processing can prevent frequent human contact with tea leaves, which may cause the tea leaves to be contaminated by bacteria and other pollutants. It can also realize the automation of tea processing and improve production efficiency. At present, the drive method used by most of the tea withering and stripping machines is a crank-connecting rod. This drive method has a dead point position and needs to pass through the dead point position through the inertia of rotational motion. During the production process, it will generate large vibrations and noise. Although a shock-absorbing device is provided at the hinge, it is still inevitable to generate noise. Moreover, the shock-absorbing device needs to withstand a large impact force and needs to be replaced frequently, wasting a lot of manpower and material resources. Tea processing personnel working in a noisy environment for a long time will harm the hearing system and make the processing personnel become anxious and restless, which is prone to accidents at work.

[0005] To this end, an automatic tea leaf withering and striping machine and a tea leaf withering and striping method are proposed, which solve the problem of large vibration and noise generated by the tea leaf withering and striping machine during operation and improve the working environment of tea processing personnel. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic tea leaf withering and striping machine and a tea leaf withering and striping method. By adopting an eccentric gear reciprocating motion driving mode, the problem of large vibration and noise generated by the crank-connecting rod driving mode of the existing tea leaf withering and striping machine is solved.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An automatic tea leaf fixing and stripping machine and a tea leaf fixing and stripping method, comprising:

[0009] Two racks, the two racks are fixedly installed on the ground;

[0010] A fixing machine, which is used to fix the fresh tea leaves;

[0011] A tea stripping machine, which is used to sort tea leaves after withering;

[0012] The fixing machine and the strip straightening machine are slidably installed between two frames. The fixing machine and the strip straightening machine are inclined to the ground and have the same inclination direction. A transmission mechanism is installed on one side of the frame, and the transmission mechanism is driven by a motor.

[0013] The transmission mechanism is a noise-reducing transmission mechanism. The noise-reducing transmission mechanism adopts eccentric gear transmission. The eccentric gear sets are meshed with each other, and there is no dead point position, thus avoiding inertial impact, running smoothly, and not generating loud noise.

[0014] Preferably, the noise reduction driving mechanism includes eccentric gear 1, eccentric gear 2, eccentric gear 3, motor, housing, push rod, slider, two cylindrical pins, support block 1 and support block 2, support block 1 is fixedly installed on the ground, support block 2 is fixedly installed on the upper surface of the frame, a housing is fixedly installed on the upper surfaces of support block 1 and support block 2, a slider is slidably installed in the housing, a push rod is fixedly installed on the side of the slider close to the frame, a slot is provided on the slider along the movement direction of the slider, cylindrical pins are fixedly installed at both ends of the slot, eccentric gear 1 and eccentric gear 3 are respectively rotatably installed on the two cylindrical pins, a gear shaft is inserted into the slot, the upper end of the gear shaft is connected to eccentric gear 2 by a spline, the number of teeth and eccentric distance of eccentric gear 1, eccentric gear 2 and eccentric gear 3 are consistent, and a pulley is fixedly installed on the lower end of the gear shaft, and the pulley is driven by the motor. When the eccentric gear 2 drives the eccentric gear 1 and the eccentric gear 2 to rotate, when the center hole of the eccentric gear 1 and the center hole of the eccentric gear 2 reach the maximum distance, the distance between the center hole of the eccentric gear 2 and the center hole of the eccentric gear 3 is the shortest, which is the maximum stroke of the push rod. The eccentric gear 2 continues to rotate, and the distance between the center hole of the eccentric gear 2 and the center hole of the eccentric gear 3 gradually increases. The slider is gradually moved away from the frame under the action of the thrust between the eccentric gear 2 and the eccentric gear 3. Under the action of the thrust, the eccentric gear 1 and the eccentric gear 2 are always kept in meshing state, and the push rod contracts. When the center hole of the eccentric gear 2 and the center hole of the eccentric gear 3 are When the hole distance reaches its maximum, the distance between the center holes of eccentric gear 1 and eccentric gear 2 is at its shortest, marking the maximum retracted stroke of the push rod. As eccentric gear 2 continues to rotate, the distance between the center holes of eccentric gear 2 and eccentric gear 1 gradually increases. The slider, acting under the thrust between eccentric gear 2 and eccentric gear 1, gradually moves toward the frame. This thrust keeps eccentric gear 3 engaged with eccentric gear 2, extending the push rod. When the distance between the center holes of eccentric gear 2 and eccentric gear 1 reaches its maximum, the distance between the center holes of eccentric gear 3 and eccentric gear 2 is at its shortest, marking the maximum extended stroke of the push rod. The push rod reciprocates once for every rotation of eccentric gear 2. The continuous rotation of eccentric gear 2 maintains this reciprocating motion. A sealed bearing is mounted between the bottom of the housing and the gear shaft.

[0015] Preferably, two pulleys (3) are mounted on the motor output shaft. The motor simultaneously drives the transmission mechanisms of the fixing machine and the strip straightener. The belt transmission method is friction-driven. Pads are provided between the housing and support blocks 1 and 2. The diameter ratio of the strip straightener pulley to the fixing machine pulley is 9:11. During the fixing and strip straightening process, the fixing machine reciprocates at 180 r / min, while the strip straightener reciprocates at 220 r / min. By adjusting the diameter ratio between the strip straightener pulley and the fixing machine pulley, the power output of the same motor can be controlled to be different, so that the same motor can simultaneously power the fixing machine and the strip straightener. Using two motors to drive the fixing machine and the strip straightener separately would increase costs and noise levels. Because the slider vibrates during reciprocation and the eccentric gear train operates, this vibration is transmitted through the housing to support blocks 1 and 2, generating noise. Pads are provided between the housing and support blocks 1 and 2 to absorb vibration and reduce noise.

[0016] Preferably, a tower-shaped rubber sleeve is fixedly installed on one side of the housing close to the frame. The tower-shaped rubber sleeve is connected to the push rod and can expand and contract with the movement of the push rod. Because the push rod needs to reciprocate, it is easy for the push rod to bring external impurities into the housing during the expansion and contraction process. The entry of impurities into the housing will aggravate the wear between the eccentric gear sets, causing the eccentric gear sets to generate noise during operation. The purpose of adding the tower-shaped rubber sleeve is to prevent external dust from entering the interior of the housing, ensuring that the eccentric gear sets can maintain optimal working conditions. At the same time, the tower-shaped rubber sleeve can also isolate the circulation of air in the housing. The circulation of air can cause the grease on the eccentric gear sets to be oxidized, resulting in the structure of the grease being destroyed and softening and loss.

[0017] Preferably, a cover is rotatably mounted on the upper surface of the housing, and a permanent magnet (1) is mounted at the interface between the cover and the housing. A handle is rotatably mounted on the upper surface of the cover, and a hole (1) is defined in the lower surface of the cover, wherein the hole (3) cooperates with the gear shaft. During use, the user can rotate the handle mounted on the cover to open the cover to replace grease and to inspect the wear of the eccentric gear set. After use, the cover is closed. Under the action of the two permanent magnets (1), the cover tightly seals the housing, and the handle adheres to the cover surface under the action of gravity. Using a magnetic method to close the cover can avoid vibration generated between the cover and the housing during operation, thereby reducing noise, facilitating use, and saving a significant amount of space. The hole (1) defined in the lower surface of the cover can serve as a limiter for the gear shaft. Because the gear shaft drives the eccentric gear (2) to rotate, the centripetal force generated by the eccentric gear (2) mostly acts on the eccentric gear (1) or the eccentric gear (3), while a small portion of the centripetal force acts directly on the gear shaft. The limiter provided by the hole (1) prevents the gear shaft from bending. Because the two cylindrical pins are short, the torque generated is relatively small and there is no need to use limiting treatment.

[0018] Preferably, multiple chutes are defined between the lower surface of the slider and the housing along the direction of the slider's movement, with multiple ball bearings (1) positioned within each chute. The upper surface of the slider is defined by multiple circular holes, each of which houses a ball bearing (2). Ball bearings (2) are used to support the eccentric gear set, which is lubricated with grease. The addition of multiple ball bearings (1) transforms the friction between the slider and the housing from sliding friction to rolling friction, significantly reducing the friction experienced by the slider during reciprocating motion, reducing the torque required to be provided by eccentric gear (2), and extending the service life of the eccentric gear set. Furthermore, the coordination between the chutes and the multiple ball bearings (1) also serves to limit the slider, restricting its movement to the chutes' trajectory and improving its stability during reciprocating motion.

[0019] Preferably, the push rod is connected to the withering strip machine through a pin structure, and insulating asbestos is provided between the push rod and the withering strip machine. The push rod and the withering strip machine can be quickly installed or disassembled through the latch structure. The purpose of adding insulating asbestos is to prevent the heat generated by the withering strip machine from being transferred into the outer shell, because the push rod is mostly made of metal, and metal has good thermal conductivity. Directly contacting the push rod with the withering strip machine will transfer the temperature of the withering strip machine into the outer shell, and the grease on the eccentric gear set in the outer shell will be subjected to the high temperature, which will accelerate the oxidation and deterioration of the grease, and generate acidic substances, reduce the lubrication performance, aggravate the wear of the eccentric gear set, and reduce the service life of the eccentric gear set. Providing insulating asbestos between the push rod and the withering strip machine can prevent the above phenomenon from occurring. At the same time, filling asbestos between the push rod and the withering strip machine can also play a certain buffering role, reducing the noise generated by the push rod when pushing the withering strip machine to move back and forth.

[0020] Preferably, the two cylindrical pins are made of zinc-aluminum alloy. Zinc-aluminum alloy has advantages such as excellent mechanical properties and wear resistance, excellent casting and machining properties, and low cost. Furthermore, zinc-aluminum alloy is a damping alloy that can absorb vibrations generated by the meshing of the eccentric gear set, thereby reducing noise generated during operation.

[0021] Preferably, the driving mode is electromagnetic drive, and two permanent magnets are installed on both sides of the withering strip machine, and electromagnets are installed on both of the frames. Buffer compression springs can be installed at both ends of the slide rod of the withering strip machine. According to the effect of the magnetic field, the same-level repels each other and the opposite-level attracts each other. By changing the direction of the current of the electromagnet installed on the frame, the magnetic level of the electromagnet is changed. Thereby achieving the purpose of the reciprocating motion of the withering strip machine. By controlling the magnitude of the electromagnet current and the frequency of the current conversion, the speed and frequency of the reciprocating motion of the withering strip machine can be controlled. However, the two permanent magnets installed on both sides of the withering strip machine need to be high-temperature resistant magnets, such as samarium cobalt magnets, because the magnetic force of conventional neodymium iron boron magnets will decrease when it is above 80 degrees Celsius. After special treatment, neodymium iron boron magnets can withstand temperatures of up to 200 degrees Celsius, but they will still be affected when working in an environment of 180 degrees Celsius. The maximum temperature that samarium cobalt magnets can withstand is 350 degrees Celsius, and they can still maintain stable magnetic force when working at high temperatures above 180 degrees Celsius. However, samarium cobalt magnets are more expensive than neodymium iron boron magnets. Adding thermal insulation material between the strip-striping machine and the second permanent magnet can lower the operating temperature of the second permanent magnet, allowing the neodymium iron boron magnet to meet operating conditions. The electromagnetic drive generates a relatively large inertial force during operation, and adding a buffer spring can provide some cushioning. While electromagnetic drive produces very little noise, the control system required for operation is more complex and costly, so users should consider this.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention adopts an eccentric gear mechanism as the driving mechanism of the withering and stripping machine. Compared with the existing crank-connecting rod driving method, the eccentric gear sets are engaged with each other, there is no dead point position, inertia impact is avoided, the operation is stable, and no loud noise is generated.

[0024] 2. The present invention defines multiple grooves between the lower surface of the slider and the housing along the direction of the slider's movement, and incorporates multiple ball bearings within the grooves. This transforms the friction between the slider and the housing from sliding friction to rolling friction, reducing the friction experienced by the slider during reciprocating motion and extending the service life of the drive device. The ball bearings also act as position limiters, restricting the slider's movement to the path of the grooves, thereby improving the slider's stability during reciprocating motion.

[0025] 3. The present invention provides heat-insulating asbestos between the push rod and the withering and stripping machine, which can prevent the heat generated by the withering and stripping machine from being transferred to the outer shell through the push rod and causing the grease to deteriorate. The heat-insulating asbestos can also play a certain buffering role, reducing the noise generated by the push rod when pushing the withering and stripping machine to move back and forth.

[0038] Example 1:

[0039] Working state: driven by eccentric gear.

[0040] refer to Figures 1 to 9The two frames 3 are fixedly mounted on the ground, and the tea fixing machine 1 and the tea strip unscrambling machine 2 are slidably mounted between the two frames 3. The tea fixing machine 1 and the tea strip unscrambling machine 2 are inclined to the ground and in the same inclination direction. The tea fixing machine 1 and the tea strip unscrambling machine 2 are both equipped with a driving device on one side of the tea leaf movement direction. The support block 1 510 is fixedly mounted on the ground, and the upper surface of the frame 3 is fixedly mounted with the support block 2 511. The upper surfaces of the support block 1 510 and the support block 2 511 are fixedly mounted with the housing 5. A slider 506 is slidably mounted in the housing 5. A push rod 505 is fixedly mounted on the side of the slider 506 close to the frame 3. A slot is provided on the slider 506 along the movement direction of the slider 506. Cylindrical pins 507 are fixedly mounted at both ends of the slot. The two cylindrical pins 507 are rotatably mounted on the eccentric gear 1 501 and the eccentric gear 3 503 respectively. The material of the two cylindrical pins 507 is zinc-aluminum alloy. A gear shaft 508 is inserted into the slot. The upper end of gear shaft 508 is splined to eccentric gear 2 502. Eccentric gears 1 501, 2 502, and 3 503 all have the same number of teeth and eccentricity. A pulley 509 is fixedly mounted on the lower end of gear shaft 508, driven by motor 504. Motor 504 simultaneously drives the transmission mechanisms of both the fixing machine 1 and the strip straightening machine 2. Pads are provided between the housing 5 and support blocks 1 510 and 2 511. A tower-shaped rubber sleeve 7 is fixedly mounted on the side of the housing 5 near the frame 3. This sleeve is attached to the push rod 505 and serves to prevent impurities from entering the housing 5. A cover 8 is rotatably mounted on the upper surface of the housing 5. A permanent magnet 1 is mounted at the interface between the cover 8 and the housing 5. A handle 10 is rotatably mounted on the upper surface of the cover 8. A hole 11 is defined on the lower surface of the cover 8, which engages with the gear shaft 508. Multiple chutes are defined between the lower surface of the slider 506 and the housing 5, along the direction of its movement. Each chute contains multiple ball bearings 1. The upper surface of the slider 506 contains multiple circular holes, each containing ball bearings 1. Ball bearings 1. Ball bearings 1. Ball bearings 1. Ball bearings 1. These ball bearings 1. The eccentric gear set is lubricated with grease. The push rod 505 is connected to the strip-striping machine 2 via a pin structure. Insulating asbestos 4 is located between the push rod 505 and the strip-striping machine 2.

[0041] The specific workflow is as follows:

[0042] Before work: Check whether there is enough grease on the eccentric gear set in the housing 5, whether there are impurities adhering to the grease, and whether the various seals on the housing 5 are damaged. After checking, start the heating tube to preheat the withering and stripping machine 2.

[0043] During operation: Motor 504 drives gear shaft 508 to rotate. Gear shaft 508 transmits power to eccentric gear 2 502, which in turn drives eccentric gear 1 501 and eccentric gear 3 503 to rotate. During the rotation of the eccentric gears, two cylindrical pins 507 transmit the thrust generated by the meshing of the eccentric gears to slider 506, enabling reciprocating motion. This is then driven by push rod 505, which drives the unwinding machine 2 to reciprocate. Motor 504 is model YS8014, with a rated speed of 1400 rpm, reduced to 110 rpm by a speed reducer. The diameter of pulley 509 for unwinding machine 2 is 18 cm, the diameter of pulley 509 for unwinding machine 2 is 22 cm, and the diameter of pulley 509 for motor 504 is 36 cm. When the motor 504 rotates at the rated speed, the reciprocating frequency of the fixing machine 1 is 180 r / min, and the reciprocating frequency of the strip straightening machine 2 is 220 r / min.

[0044] After working: After the tea leaves have been withered and sorted, they will fall from the lower end of the sorting machine 2 onto the conveyor belt under the action of the inclined surface and reciprocating vibration of the sorting machine 2. The conveyor belt will transport the sorted tea leaves to the drying equipment. After drying, the tea leaves will be sent to the collection box, and the tea leaves in the collection box are finished tea leaves.

[0045] Example 2:

[0046] Working status: electromagnetically driven.

[0047] refer to Figures 10 and 11 , permanent magnets 13 are installed on both sides of the withering and stripping machine 2, electromagnets 12 are installed on both frames 3, and buffer compression springs are installed on both ends of the sliding rod of the withering and stripping machine 2. According to the effect of the magnetic field, the same-level repels each other and the different-level attracts each other. By changing the direction of the current of the electromagnet 12 installed on the frame 3, the magnetic level of the electromagnet 12 is changed. Thereby achieving the purpose of the reciprocating motion of the withering and stripping machine 2. By controlling the magnitude of the current of the electromagnet 12 and the frequency of the current conversion, the speed and frequency of the reciprocating motion of the withering and stripping machine 2 can be controlled. The noise generated by driving the withering and stripping machine 2 to reciprocate by magnetic force is very small, and the controllability is high. The reciprocating speed and frequency of the withering and stripping machine 2 can be changed according to different tea leaves. At the same time, the length of the compression spring can also be changed to achieve the change of the reciprocating distance. However, since the reciprocating frequencies required by the withering and stripping machine 1 and the stripping machine 2 are inconsistent, at least 4 electromagnets 12 need to be installed, which increases a certain cost.

[0048] The above two embodiments are merely examples among the many embodiments of the present invention. Various changes are possible without violating the principles of the present invention. The embodiments produced by those skilled in the art who modify the present invention without creative work also fall within the scope of protection of the present invention.
