Abstract
Description
Technical Field
[0001] This application relates to the field of tea processing technology, specifically to a kneading and fixing device for green tea processing. Background Technology
[0002] Green tea is a type of tea that has not undergone fermentation, retaining its unique original flavor and characteristics of green leaves and green liquor. Green tea has the effects of refreshing the mind, clearing heat and relieving summer heat, and aiding digestion and resolving phlegm. The processing technology of green tea includes picking, spreading, fixing, rolling, drying, and storage. Among them, rolling is divided into manual rolling and machine rolling. Machine rolling uses mechanical force to make the fixed green leaves form tight strips under the interaction of various forces such as pushing, pressing, twisting, and friction in the rolling barrel. At the same time, it breaks down the cell tissue of the leaves, promotes the oxidation of some enzymes, reduces the bitterness of pan-fired green tea, and increases the rich and mellow taste.
[0003] Existing rolling machines mainly consist of a frame, transmission mechanism, rolling drum, lifting mechanism, rolling disc, and rotation mechanism. The withered tea leaves are placed in the rolling drum, and a pressure cap is placed inside the drum above the tea leaves. The pressure cap rises and falls under the action of the lifting mechanism, applying pressure to the tea leaves. As the rolling drum moves, the tea leaves at the bottom contact the rolling disc to achieve rolling. This method of pressing down with the pressure cap has certain shortcomings. When the lower layer of tea leaves is being rolled, the tea leaves in the middle and upper layers experience greater pressure. Under excessive pressure, the tea leaves are squeezed together, easily clumping and forming clumps. This results in uneven tea leaf shaping during subsequent rolling, low efficiency, and affects the quality of the finished product. Therefore, this application proposes a rolling and withering device for green tea processing. Utility Model Content
[0004] The purpose of this application is to provide a kneading and fixing device for green tea processing in order to solve the problems mentioned above in the background art.
[0005] To achieve the above objectives, this application specifically adopts the following technical solution:
[0006] A rolling and fixing device for green tea processing, comprising:
[0007] The kneading disc has three legs on its outer periphery, and several first ribs arranged in a ring on the inner bottom wall of the kneading disc. A discharge hole is opened through the center of the kneading disc, and a sealing component for sealing the discharge hole is provided at the bottom of the kneading disc.
[0008] The kneading drum has three rotating rods that rotatably pass through each of its three support legs. The ends of the three rotating rods are hinged to movable frames. The kneading drum is mounted on the movable frames. One end of one of the rotating rods is connected to a motor mounted on a support leg. A base is rotatably fitted onto the bottom of the kneading drum. A material discharge chute is opened through the base. A guide rod is coaxially fixed on the base. A spiral plate is fixed on the guide rod. A drive component for driving the base to rotate is provided on the kneading drum.
[0009] Furthermore, the driving component includes a first toothed ring fixed on the chassis, and a first gear fixed on the kneading disc, wherein the first toothed ring and the first gear intermittently mesh.
[0010] Furthermore, a bracket is fixedly provided on the kneading drum, and the guide rod rotates through the bracket. A limiting component is provided on the bracket to restrict the rotation of the guide rod.
[0011] Furthermore, the limiting component includes a ratchet fixed on the guide rod, a column is provided on the bracket, a pawl that meshes with the ratchet is rotatably sleeved on the column, and a torsion spring sleeved on the column connects the pawl and the bracket.
[0012] Furthermore, the sealing component includes a housing disposed at the bottom of the kneading disc, an adjusting rod rotatably passing through the housing, a sealing plate connected to the adjusting rod via a support rod and engaging with the discharge hole, a worm gear fixedly disposed on the adjusting rod, and a worm gear rotatably disposed on the housing and meshing with the worm gear.
[0013] Furthermore, the sealing plate is provided with several second ridges arranged in a ring.
[0014] Furthermore, a second toothed ring is rotatably fitted on the housing, and a second gear is fixed on each of the three rotating rods, with all three second gears meshing with the teeth of the second toothed ring.
[0015] Furthermore, a partition is connected between the spiral plate and the chassis.
[0016] The beneficial effects of this application are as follows:
[0017] In this application, a base plate is rotated at the bottom of the kneading drum, and a guide rod and a spiral plate are installed on the base plate. When the kneading drum makes an inward circular motion, the rotation of the spiral plate applies a downward transmission pressure to the tea leaves, so that the tea leaves can be effectively kneaded. Compared with the existing method of relying on the pressure of the lid, which can easily lead to excessive pressure on the tea leaves, the spiral plate is placed in layers and conveyed by a spiral to provide downward pressure. This method can ensure that the tea leaves are effectively kneaded while meeting the normal pressure requirements, without causing excessive compression of the tea leaves, avoiding clumping, and making the tea leaves uniformly shaped during kneading, thus improving the quality of the finished product.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figures 1-7 As shown in one embodiment of this application, a kneading and fixing device for green tea processing includes:
[0028] The kneading disc 1 has three supporting legs 2 arranged in a ring on its outer periphery. The inner bottom wall of the kneading disc 1 has several first ribs 3 arranged in a ring. The first ribs 3 are arc-shaped. The center of the kneading disc 1 has a discharge hole 4. The bottom of the kneading disc 1 has a sealing element 5 for sealing the discharge hole 4. When kneading the tea leaves, the sealing element 5 seals the discharge hole 4. When the tea leaves need to be discharged after kneading, the sealing element 5 is released, and the kneaded tea leaves can be discharged from the discharge hole 4.
[0029] The kneading drum 6 has three rotating rods 7 rotatably passing through each of its three support legs 2. The ends of the three rotating rods 7 are hinged to movable frames 8. Preferably, the rotating rods 7 are L-shaped, including connected vertical rods and first horizontal plates. The vertical rods are rotatably connected to the support legs 2. The movable frame 8 includes a ring body, with three second horizontal plates connected to the outer periphery of the ring body. The three second horizontal plates are respectively hinged to three first horizontal plates. The kneading drum 6 is mounted on the movable frame 8, with openings at both the top and bottom. The kneading drum 6 is coaxially mounted on the ring body. The end of one of the rotating rods 7 is connected to a movable frame 8 mounted on the support legs 2. Motor 9 on leg 2 performs work, and its output shaft drives one of the rotating rods 7 to rotate. Since the rotating rod 7 is L-shaped and the ends of the three rotating rods 7 rotate with the movable frame 8 respectively, all three rotating rods 7 will rotate, thereby driving the movable frame 8 to move inward in a circular motion, which in turn drives the kneading drum 6 to move inward in a circular motion. The bottom end of the kneading drum 6 is rotatably fitted with a base plate 10. Preferably, there is a gap between the base plate 10 and the kneading disc 1, and the bottom of the base plate 10 has a placement space for placing tea leaves. A dropper is provided through the base plate 10. A guide rod 12 is coaxially fixed on the material trough 11 and the base 10. A spiral plate 13 is fixed on the guide rod 12. A drive component 14 for driving the base 10 to rotate is provided on the kneading pan 1. When kneading the tea, the tea is poured onto the spiral plate 13 and will spiral down along the spiral plate 13, thus filling the entire kneading pan 6. The tea in the kneading pan 6 will fall through the material drop trough 11 to the space below the base 10. The tea is located in the placement space below the base 10 (i.e., in the gap between the base 10 and the kneading pan 1). When the kneading pan 6 makes an inward circular motion... When in motion, the tea leaves are gripped by the base 10 and come into contact with the first rib 3 on the kneading disc 1, thus kneading the tea leaves. Due to the spiral structure of the spiral plate 13, the tea leaves will spiral down, and the drive component 14 drives the base 10 to rotate, thereby driving the guide rod 12 and the spiral plate 13 to rotate. When the spiral plate 13 rotates, it will apply a downward conveying force to the tea leaves. This conveying force will apply a certain pressure to the tea leaves. Under this pressure and the inward circular motion of the kneading drum 6, the tea leaves will be kneaded.
[0030] In this design, a base plate 10 is rotated at the bottom of the kneading drum 6. A guide rod 12 and a spiral plate 13 are mounted on the base plate 10. When the kneading drum 6 makes an inward circular motion, the rotation of the spiral plate 13 applies a downward transmission pressure to the tea leaves, allowing the tea leaves to be effectively kneaded. Compared with the existing method of relying on the pressure of the lid, which can easily lead to excessive pressure on the tea leaves, the spiral plate 13 is placed in layers and spirally conveyed to provide downward pressure. This method ensures that the tea leaves are effectively kneaded while meeting the normal pressure requirements, without causing excessive compression or clumping. This results in uniform tea leaf formation during kneading and improves the quality of the finished product.
[0031] like Figure 7As shown, in some embodiments, the drive component 14 includes a first gear ring 1401 fixed on the chassis 10, and a first gear 1402 fixed on the kneading disc 1. The first gear ring 1401 and the first gear 1402 intermittently mesh. Since the kneading drum 6 performs an inscribed circular motion, it moves along a specific trajectory. Therefore, when the kneading drum 6 moves, after the kneading drum 6 completes one revolution of the inscribed circle, the first gear 1402 and the first gear ring 1401 engage (intermittent meshing), and the stroke of each meshing is very short. This allows the spiral plate 13 to rotate slightly each time. Through intermittent tooth meshing, even though the kneading drum 6 is in continuous in tangential circular motion, the spiral plate 13 rotates slowly (the gap between the base 10 and the kneading disc 1 is limited, and the amount of tea leaves that pass through after kneading is limited. The continuous rotation of the spiral plate 13 will continuously apply a conveying force to the tea leaves, and the continuous application of the conveying force will increase the pressure on the tea leaves). This ensures that the tea leaves are effectively conveyed downwards without causing excessively fast conveying, thus avoiding excessive pressure on the tea leaves and improving practicality.
[0032] like Figure 2 As shown, in some embodiments, a bracket 15 is fixed on the kneading drum 6, and the guide rod 12 rotates through the bracket 15. A limiting member 16 is provided on the bracket 15 to restrict the rotation of the guide rod 12. Through the bracket 15, both the upper and lower ends of the guide rod 12 have support points. Since the first gear 1402 and the first gear ring 1401 are intermittently meshed, and the kneading drum 6 is in tangential circular motion, when the first gear 1402 and the first gear ring 1401 come into contact and mesh, the chassis 10 is easily rotated by the stress of the kneading drum 6. The limiting member 16 is used to limit the chassis 10 from rotating when the first gear 1402 and the first gear ring 1401 are not meshing, or to prevent the guide rod 12 from reversing, so as to avoid conveying the tea leaves upward under the stress of reversing.
[0033] like Figure 6 As shown, in some embodiments, the limiting member 16 includes a ratchet 1601 fixed on the guide rod 12, a column 1602 provided on the bracket 15, a pawl 1603 rotatably sleeved on the column 1602 that meshes with the ratchet 1601, and a torsion spring 1604 sleeved on the column 1602 connecting the pawl 1603 and the bracket 15. In the initial state without external force interference, under the elastic force of the torsion spring 1604, the end of the pawl 1603 is engaged in the ratchet teeth of the ratchet 1601, such as... Figure 6As shown, the teeth of the first gear ring 1401 and the first gear 1402 are engaged. The guide rod 12 rotates clockwise normally. When the ratchet 1601 rotates clockwise, it will release the pawl 1603, so as not to affect the normal rotation of the guide rod 12, but it will restrict the guide rod 12 from rotating counterclockwise. When the first gear 1402 and the first gear ring 1401 are not engaged, the end of the pawl 1603 is locked in the teeth of the ratchet 1601, thereby restricting the guide rod 12 and the chassis 10 from rotating.
[0034] like Figure 4 As shown, in some embodiments, the sealing component 5 includes a housing 501 disposed at the bottom of the kneading disc 1. An adjusting rod 502 is rotatably passed through the housing 501. A sealing plate 503, which is inserted into the discharge hole 4, is connected to the adjusting rod 502 via a support rod. A worm gear 504 is fixedly disposed on the adjusting rod 502. A worm 505 is rotatably disposed on the housing 501 and meshes with the worm gear 504. Twisting the worm 505 causes the adjusting rod 502 to rotate under the meshing of the worm 505 and the worm gear 504, thereby achieving the sealing or unsealing of the discharge hole 4 by the sealing plate 503. At the same time, the cooperation between the worm gear 504 and the worm 505 has self-locking properties to ensure the stability after sealing.
[0035] like Figure 4 As shown, in some embodiments, the sealing plate 503 is provided with a plurality of second ribs 17 arranged in a ring. By providing the second ribs 17 on the sealing plate 503, when the sealing plate 503 blocks the discharge hole 4, the first ribs 3 and the second ribs 17 work together to rub the tea leaves, further improving the rubbing effect on the tea leaves.
[0036] like Figure 3 and Figure 7 As shown, in some embodiments, a second toothed ring 18 is rotatably mounted on the housing 501, and a second gear 19 is fixed on each of the three rotating rods 7. The three second gears 19 mesh with the teeth of the second toothed ring 18. Through the meshing of the teeth of the second gears 19 and the second toothed ring 18, the driving force of the motor 9 will act on the three rotating rods 7, thereby causing the three rotating rods 7 to rotate synchronously and apply stress, making the kneading drum 6 more stable when making inscribed circular motion, and further improving the kneading effect on the tea leaves.
[0037] like Figure 5 As shown, in some embodiments, a partition 20 is connected between the spiral plate 13 and the chassis 10. Preferably, the partition 20 is adjacent to the discharge chute 11. By setting the partition 20, the tea leaves are limited, so that when the tea leaves slide down the spiral plate 13, they can fall more smoothly through the discharge chute 11 without leaving too much residue on the top of the chassis 10, thereby improving practicality.
[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
