Description

Technical Field

[0001] This invention relates to the field of tea separation equipment, specifically to an antibacterial and moisture-proof tea separation system and method. Background Technology

[0002] Tea leaves refer to the leaves and buds of the tea plant. More broadly, it refers to the leaves of the evergreen shrub tea plant, which can be used to make tea, and the beverage made from these leaves. Later, it came to mean all herbal teas made from the flowers, leaves, seeds, and roots of plants.

[0003] During tea production and processing, tea leaves and stems need to be separated to improve tea quality. Existing tea production separation devices are inefficient, still require manual sorting, and their separation effects are not ideal. Furthermore, their methods for moisture prevention and antibacterial properties are rather limited. Therefore, this invention proposes a new solution. Summary of the Invention

[0004] The purpose of this invention is to provide an antibacterial and moisture-proof tea separation system and method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an antibacterial and moisture-proof tea separation system, comprising a conveying mechanism, a screening mechanism, a stem scraping mechanism, and a feeding mechanism. The screening mechanism is fixedly installed on the top surface of the conveying mechanism. The upper surface of the box on the conveying mechanism is fixedly connected to the lower surface of the shell on the screening mechanism. The stem scraping mechanism is movably installed inside the shell. The feeding mechanism is fixedly installed on the upper surface of the shell.

[0006] The conveying mechanism includes a housing, a roller, a hopper, four rubber rollers, a first motor, and a blower. The roller is horizontally rotatable inside the housing. The discharge port of the roller is close to the outer surface of the housing, and the inlet of the roller is connected to the hopper. The hopper inlet is fixed to the housing with its inlet facing upward. The four rubber rollers are symmetrically rotatable in pairs on the lower surface inside the housing. The two rubber rollers on the same side are fixedly connected to the output end of the first motor through a rotating shaft. The surface of each rubber roller is in rotatable contact with the outer surface of the roller. The contact surface between the roller and the rubber rollers is provided with anti-slip texture. A blower is also fixedly installed inside the housing. A guide hole is opened at the bottom of the hopper, and the blower nozzle is set corresponding to the guide hole.

[0007] The screening mechanism includes a housing, a first chute, a vibrating screen, push rods, extrusion rods, annular baffles, a support frame, a cam, a linkage shaft, a first sprocket, a second sprocket, a second motor, and a first compression spring. The housing has a concave structure and a first chute. A vibrating screen is slidably arranged between the two first chutes. Two push rods are vertically fixed on the lower surface of the opposite sides of the vibrating screen away from the drum. The side surface of the push rod is fixedly connected to one end of the extrusion rod. An annular baffle is welded to the middle of the extrusion rod. The annular baffle elastically abuts against the bottom side surface of the first chute through the first compression spring. A part of the extrusion rod away from the annular baffle slides through the support frame. The other end of the extrusion rod extending out of the support frame movably abuts against the surface of the cam. The cam is fixed on the linkage shaft. A first sprocket is fixed to the end of the linkage shaft away from the side surface of the housing. The first sprocket and the second sprocket are connected by chain drive. The second sprocket is fixed to one end of the output shaft of the second motor. The second motor is fixedly arranged on one side of the first chute.

[0008] The scraping mechanism includes a second slide groove, a rocker arm, a fixed rod, a connecting rod, a round rod, a triangular rake, and a second compression spring. A second slide groove is also provided on the outermost side of the housing near the first slide groove. A slider slides through the second slide groove, and a second compression spring is sleeved between the slider and the end of the second slide groove near the push rod. One side of the slider is slidably connected to the slide groove of the rocker arm. The end of the rocker arm away from the slide groove is hinged to the fixed rod. The fixed rod is fixedly located at the bottom of the second slide groove on the side away from the second compression spring. The middle part of the rocker arm is hinged to one end of the connecting rod. A round rod is fixed to the end face of the protruding part of the cam, and the round rod is hinged to the other end of the connecting rod. The top surface of the slider is connected to the bottom end of the triangular rake. The side away from the push rod is fixedly connected, and the top of the second slide groove is fixedly fixed on the side away from the slider. The triangular rake is welded from several steel plates. Each steel plate is inclined and has a storage groove on its upper surface. The bottom of the triangular rake is rotatably connected to the side near the push rod. The triangular rake is slidably set on the upper surface of the vibrating screen. The rotating rake is welded from several steel wires. The number of steel wires on the rotating rake is an even number more than the number of steel plates on the triangular rake. The steel wires can be moved and placed in the storage grooves at the corresponding positions. The steel wires at the bottom of both sides of the rotating rake are moved and placed in the second slide groove. The surface of the steel wires at the bottom of both sides of the rotating rake intermittently abuts against the surface of the limiting post.

[0009] Preferably, a torsion spring is also fitted at the bottom of the triangular rake and the rotating part of the flip rake, with one end of the torsion spring fixed to the triangular rake and the other end of the torsion spring fixed to the flip rake.

[0010] Preferably, the feeding mechanism includes a hopper and a protective cover. The lower surface of the hopper is fixedly mounted on the top of the protective cover, and the protective cover is fixedly mounted on the upper surface of the housing. The rotating rake is movably inserted through the inner and outer surfaces of the protective cover and the recess of the housing.

[0011] Preferably, the linkage shaft is rotated and inserted into the inner walls of the first and second slide grooves.

[0012] A method for separating tea leaves that is antibacterial and moisture-proof:

[0013] Step 1: Place the mixed material of tea leaves and tea stems that have not been separated into the hopper. The tea leaves and tea stems will fall into the screening mechanism through the hopper for separation and screening.

[0014] Step 2: The vibrating screen on the screening mechanism continuously slides along the first chute to filter the tea leaves and drop them into the hopper. The tea stems are separated from the device and collected by the triangular rake and the flipping rake on the stem scraping mechanism.

[0015] Step 3: Use a hairdryer to blow hot air into the hopper to dry and sterilize the separated tea leaves.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention drives the linkage shaft to rotate through the second motor, so that the cam on the linkage shaft simultaneously drives the screening mechanism and the stem scraping mechanism to continuously reciprocate in the housing. Through rapid reciprocating movement, the tea leaves and tea stems are quickly separated. By controlling the air volume and temperature through the blower, hot air can be blown into the feed hopper to dry and ventilate the separated tea leaves, thereby achieving the effect of moisture prevention and antibacterial properties.

Except for the triangular rake 3.6, all other structures and components of the scraping mechanism 3 are arranged opposite each other along the length of the recess in the housing 2.1. A second slide groove 3.1 is also provided on the outermost side of the housing 2.1 near the first slide groove 2.2. A slider 3.11 slides through the second slide groove 3.1. The slider 3.11 is located near the push rod 2.4. A second compression spring 6 is sleeved between the ends. A slider 3.11 slides through a groove 3.21 within a rocker arm 3.2. The end of the rocker arm 3.2 away from the groove 3.21 is hinged to a fixed rod 3.3. The fixed rod 3.3 is fixedly located at the bottom of the second groove 3.1 on the side away from the second compression spring 6. The middle part of the rocker arm 3.2 is hinged to one end of a connecting rod 3.4. A round rod 3.5 is fixed to the end face of the protruding portion of the cam 2.8 away from the first groove 2.2. The round rod 3.5 is connected to the connecting rod 3.4. The other end is hinged; the top surface of the slider 3.11 is fixedly connected to the bottom end of the triangular rake 3.6 on the side away from the push rod 2.4; a limit post 3.12 is fixed on the top of the second slide groove 3.1 on the side away from the slider 3.11; the triangular rake 3.6 is welded from several steel strips 3.61; each steel strip 3.61 has a storage groove 3.62 on its inclined upper surface; a flip rake 3.63 is rotatably connected to the bottom end of the triangular rake 3.6 near the push rod 2.4; the triangular rake 3.6 is slidably set... On the upper surface of the vibrating screen 2.3, the tilting rake 3.63 is welded from several steel wires 3.64. The number of steel wires 3.64 on the tilting rake 3.63 is an even number more than the number of steel strips 3.61 on the triangular rake 3.6. The steel wires 3.64 can be movably inserted into the corresponding receiving grooves 3.62. The steel wires 3.64 on both sides of the bottom of the tilting rake 3.63 are movably inserted into the second sliding groove 3.1. The surfaces of the steel wires 3.64 on both sides of the bottom of the tilting rake 3.63 are in movable contact with the surfaces of the limiting posts 3.12. A torsion spring 3.65 is also sleeved on the bottom of the triangular rake 3.6 and the rotating part of the tilting rake 3.63. One end of the torsion spring 3.65 is fixed to the triangular rake 3.6, and the other end of the torsion spring 3.65 is fixed to the tilting rake 3.63.

[0029] Please see Figure 2-6The working principle of this invention is as follows: The second motor 2.12 rotates, driving the linkage shaft 2.9 to rotate via a chain. The linkage shaft 2.9 drives the cam 2.8 to rotate. When the cam 2.8 rotates, the convex surface of the cam 2.8 (with a gradually increasing radius) squeezes the extrusion rod 2.5, while the first compression spring 5 is compressed. When the convex surface of the cam 2.8 (with a gradually decreasing radius) no longer squeezes the extrusion rod 2.5, the first compression spring 5 elastically returns to its original position. Thus, during the rotation of the cam 2.8, the screening mechanism 2 continuously reciprocates along the length of the first slide groove 2.2. Simultaneously, the rotation of the cam 2.8 drives the connecting rod 3.4 to move, and the connecting rod 3.4 drives the rocker arm 3.2 to swing. During the swing of the rocker arm 3.2, the slider 3.11 is forced to slide along the second slide groove 3.1. During the sliding process, the second compression spring 6 is compressed, and the bottom front end of the triangular rake 3.6 moves along the vibrating screen 2.3. When the steel wires 3 at the bottom front ends of both sides of the flip rake 3.63... When the surface of the steel wire 3.64 moves to and contacts the limiting post 3.12, the limiting post 3.12 forces the bottom end of the steel wire 3.64 to move backward, causing the torsion spring 3.65 to compress, causing the flipping rake 3.63 to flip and separate the tea stems out of the device. At this time, the end face of the extrusion rod 2.5 is exactly at the maximum radius distance of the cam 2.8 from the axis of the linkage shaft 2.9. When the cam 2.8 continues to rotate at this time, the second compression spring 6 elastically returns to its original position, and at the same time the rocker arm 3.2, the connecting rod 3.4 and the triangular rake 3. .6 The corresponding activity is reset, and the flipping rake 3.63 is elastically reset by the torsion spring 3.65, realizing the storage process of the flipping rake 3.63. In this way, the rotation of the cam 2.8 can also drive the scraping mechanism 3 to slide back and forth along the length direction of the second slide groove 3.1. Furthermore, when the separated tea leaves fall into the feed hopper 1.3, the blower 1.6 blows hot air into the feed hopper to ensure that the tea leaves are in a dry and sterile environment during the separation process. Finally, the tea leaves are produced by the roller 1.2.

[0030] A tea separation method with antibacterial and moisture-proof properties, employing an antibacterial and moisture-proof tea separation system, includes the following specific steps:

[0031] Step 1: Place the mixed material of tea leaves and tea stems that have not been separated into the hopper 4.1. The tea leaves and tea stems will fall into the screening mechanism 2 through the hopper 4.1 for separation and screening.

[0032] Step 2: The vibrating screen 2.3 on the screening mechanism 2 continuously slides along the first chute 2.2 to filter the tea leaves and drop them into the feed hopper 1.3. The tea stems are separated from the device and received by the triangular rake 3.6 and the flipping rake 3.62 on the scraping mechanism 3.

[0033] Step 3: Use the blower 1.6 to blow hot air onto the feed hopper 1.3 to dry and sterilize the separated tea leaves.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
