Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, specifically a kneading machine for tea processing. Background Technology

[0002] A rolling machine is a tea processing machine that processes tea leaves after they have been withered (killed green). It can preserve the fiber structure of the tea leaves and ensure that the tea quality is uniform. The rolling drum repeatedly rolls and compresses the tea leaves to meet the processing requirements.

[0003] The height of the ridges (or ribs) on the surface of the kneading disc of existing kneading machines is fixed. Through the raised structure, it applies pressure and friction to the tea leaves during the kneading process, forcing the tea leaves to curl into strips. However, the required ridge height varies depending on the processing needs of different teas. For example, black tea requires a higher ridge height, while green tea requires a lower one. This results in poor adaptability of existing equipment, making it difficult to meet the usage requirements. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a kneading machine for tea processing, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a kneading machine for tea processing, comprising a kneading disc and a kneading cylinder; the bottom of the kneading disc is provided with a height adjustment mechanism and a feeding mechanism, a driving mechanism is provided on one side of the kneading disc, and a feeding mechanism is installed on the kneading disc; the kneading cylinder is located above the kneading disc, a pulling frame is sleeved on the outer periphery of the kneading cylinder, and three connecting arms arranged in a circular array are provided on the outer periphery of the pulling frame, with a swinging plate hinged to the outer end of any connecting arm; three support plates are fixed in a circular array on the outer periphery of the kneading disc, and the outer end of the swinging plate is rotatably connected to the support plates; a support shell is fixed at the bottom of the support plates.

[0006] The height adjustment mechanism includes two support frames, which are distributed on the left and right sides of the bottom of the kneading disc. An electric cylinder is installed on the support frame, one end of which passes through the support frame and is connected to the mounting plate. The upper surface of the mounting plate has a rotationally symmetrical mounting groove. Ribs are detachably installed inside the mounting groove. A through groove is opened in the middle of the mounting plate. Multiple adjustment through grooves that cooperate with the ribs are opened on the surface of the kneading disc.

[0007] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0008] The height adjustment mechanism uses an electric cylinder to drive the mounting plate to rise and fall, achieving stepless adjustment of the rib height. This significantly improves the equipment's adaptability to different types of tea. For example, when processing black tea, the rib can be raised to increase cell breakage and promote tea juice seepage and fermentation; when processing green tea, the rib can be lowered to reduce tea breakage and preserve the integrity of the tea leaves. The detachable rib design supports modular replacement, allowing tea factories to select ribs of different shapes or materials according to their process requirements. This mechanism breaks through the limitations of traditional fixed ribs, reducing the cost for tea companies to purchase multiple machines. At the same time, it achieves standardized production through parametric control, reducing reliance on operator experience. Attached Figure Description

[0017] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0018] like Figure 1-7As shown, a kneading machine for tea processing includes a kneading disc 1 and a kneading cylinder 6; the bottom of the kneading disc 1 is provided with a height adjustment mechanism 2 and a feeding mechanism 3, a drive mechanism 4 is provided on one side of the kneading disc 1, and a feeding mechanism 5 is installed on the kneading disc 1; the kneading cylinder 6 is located above the kneading disc 1, a pull frame 7 is sleeved on the outer periphery of the kneading cylinder 6, and three connecting arms arranged in a circular array are provided on the outer periphery of the pull frame 7. A swing rotating plate 8 is hinged to the outer end of any connecting arm. Three support plates 9 are fixed in a circular array on the outer periphery of the kneading disc 1. The outer end of the swing rotating plate 8 is rotatably connected to the support plate 9, and a support shell 10 is fixed to the bottom of the support plate 9;

[0019] The height adjustment mechanism 2 includes two support frames 201, which are distributed on the left and right sides of the bottom of the kneading disc 1. An electric cylinder 202 is installed on the support frame 201. One end of the electric cylinder 202 passes through the support frame 201 and is connected to the mounting plate 203. The upper surface of the mounting plate 203 is provided with a rotationally symmetrical mounting groove 204. A rib 205 is detachably installed inside the mounting groove 204. A through groove 206 is provided in the middle of the mounting plate 203. The surface of the kneading disc 1 is provided with multiple adjustment through grooves that cooperate with the rib 205 to pass through.

[0020] Through the above technical solution, when the electric cylinder 202 retracts, the mounting plate 203 drives the rib 205 to sink, at which time the kneading pressure decreases; conversely, when the electric cylinder 202 extends, the rib 205 protrudes higher, enhancing the squeezing and friction on the tea leaves. The adjustment groove design allows the rib 205 to form a protruding structure with the surface of the kneading disc 1 at different heights. The kneading cylinder 6 is connected to the swing plate 8 through the pull frame 7. The support plate 9 and the support shell 10 provide stable support. The drive mechanism 4 can transmit power, enabling the kneading cylinder 6 to perform swing kneading action. The linear drive of the electric cylinder 202 achieves stepless adjustment of the height of the rib 205, which can quickly adjust the kneading pressure and friction for different types of tea, significantly improving the adaptability of the equipment. The detachable rib 205 design allows for the replacement of ribs 205 of different shapes according to process requirements, enhancing processing flexibility. Through the above design, a multi-purpose machine is achieved, reducing the cost for tea companies to purchase multiple machines.

[0021] The feeding mechanism 3 includes a circular baffle 301. The kneading disc 1 has a feeding groove in the middle that accommodates the circular baffle 301. The circular baffle 301 is located in the feeding groove. A connecting frame 302 is fixed to the bottom of the kneading disc 1. A protruding plate 303 is fixed to the bottom side of the circular baffle 301. The protruding plate 303 is hinged to the connecting frame 302. An extension frame 304 is provided at the bottom of the support frame 201. A cylinder 305 is hinged to the extension frame 304. A U-shaped plate 306 is hinged to the top of the cylinder 305. The U-shaped plate 306 is fixed to the bottom of the circular baffle 301 to drive the circular baffle 301 to rotate.

[0022] With the above technical solution, after the kneading is completed, the cylinder 305 retracts and pulls the U-shaped plate 306, causing the circular baffle 301 to rotate and tilt around the hinge point of the protruding plate 303 and the connecting frame 302, opening the feeding trough. The tea leaves fall through the through trough 206 into the collection device prepared by the user below. When the cylinder 305 extends, the circular baffle 301 returns to its original position parallel to the surface of the kneading disc 1, closing the feeding trough.

[0023] The drive mechanism 4 includes a support 401, which is located next to the kneading disc 1. A motor 402 and a worm gear reducer 403 are fixed on the top of the support 401. The output shaft of the motor 402 is fixedly connected to the input end of the worm gear reducer 403. Pulleys 404 are fixed below the output shaft of the worm gear reducer 403 and the surface of the left swing plate 8. The pulleys 404 on both sides are connected by belt drive.

[0024] Through the above technical solution, the power output of motor 402 is reduced in speed and increased in torque by worm gear reducer 403, and then transmitted to the left swing plate 8 through pulley 404 and belt, which drives the kneading cylinder 6 to swing around the rotation point of support plate 9 to realize the kneading action. The self-locking characteristic of worm gear reducer 403 can prevent the kneading cylinder 6 from moving accidentally due to inertia when the machine stops.

[0025] The feeding mechanism 5 includes a rotating rod 501, which is rotatably connected to one side of the pulling frame 7. An extension arm 502 is fixedly connected to the surface of the rotating rod 501. A screw 503 is threaded through the extension arm 502. A lower pressure plate 504 is installed at the bottom of the screw 503. The lower pressure plate 504 is slidably connected to the inner wall of the kneading cylinder 6. The lower pressure plate 504 can detach from the kneading cylinder 6 and detach from the kneading cylinder 6 by the rotation of the extension arm 502.

[0026] Through the above technical solution, the rotating rod 501 can drive the extension arm 502 to rotate above the kneading cylinder 6. The height of the lower pressure plate 504 is adjusted by rotating the screw 503 to press the tea leaves. After kneading is completed, the screw 503 is rotated in the opposite direction to raise the lower pressure plate 504. Then the extension arm 502 rotates and moves away from above the kneading cylinder 6 to allow for feeding.

[0027] The diameter of the through groove 206 is larger than the diameter of the circular baffle 301.

[0028] With the above technical solution, the diameter of the through groove 206 is larger than that of the circular baffle 301, which ensures that the material feeding process is unobstructed and also avoids contact between the circular baffle 301 and the through groove 206.

[0029] The mounting groove 204 and the rib 205 are both provided with multiple threaded holes 207 at their bottoms. The mounting groove 204 and the rib 205 are detachably connected by bolts through the threaded holes 207.

[0030] With the above technical solution, the mounting groove 204 and the rib 205 are connected by bolts through the bottom threaded hole 207, which allows for quick disassembly and replacement of the rib 205. During operation, the old rib 205 can be removed by loosening the bolts, and the new rib 205 can be replaced by tightening the bolts to fix it.

[0031] Two guide rods 208 slide through the surface of the support frame 201, and the top of the guide rods 208 are fixedly connected to the bottom of the mounting plate 203.

[0032] With the above technical solution, when the electric cylinder 202 drives the mounting plate 203 to rise and fall, the guide rod 208 slides along the support frame 201, limiting the lateral displacement of the mounting plate 203.

[0033] Working principle: First, the operator sets the height of the rib 205 according to the type of tea through the height adjustment mechanism 2: the electric cylinder 202 extends and drives the mounting plate 203 to rise and fall, the guide rod 208 guides the mounting plate 203 to move vertically, and the rib 205 protrudes from the adjustment groove to the preset height. When feeding, tea leaves are first added inside the kneading cylinder 6, and then the extension arm 502 is rotated to the top of the kneading cylinder 6. The rotating screw 503 causes the lower pressure plate 504 to press down and fix the tea leaves. Then the drive mechanism 4 is started. The motor 402 is reduced in speed by the worm gear reducer 403 and drives the swing plate 8 through the pulley 404 to make the kneading cylinder 6 swing back and forth. The tea leaves gradually curl into strips under the squeezing and friction action between the surface of the kneading plate 1 and the rib 205. After kneading, the cylinder 305 of the feeding mechanism 3 retracts and pulls the U-shaped plate 306 to tilt the circular baffle 301. The tea leaves are discharged through the through groove 206.
