Description

Technical Field

[0001] The invention relates to the field of tea production equipment, in particular to a tea bagging, kneading and dispersing machine. Background Art

[0002] Rolling is a necessary production process for oolong tea to continue shaping its unique curled and tight appearance based on the initial rolling and twisting. Rolling means drying the rolled leaves until they are 70% to 80% dry, placing the dried leaves in a white cloth square towel while they are still hot, lifting the four corners of the square towel, shaking and tightening it to make it into a ball shape. After the cloth mouth is fixed, the tea ball is placed on the rolling machine and rotated under the extrusion drive of the rolling machine. This process rolls the tea ball tightly and shapes it. The complete shaping process is rolling, flat rolling, breaking up and drying, and the above process is repeated 2-4 times. In actual production, rolling is also divided into initial rolling and repeated rolling. After several rolling, flat rolling and breaking up, the tea leaves are gradually shaped into the unique shape of oolong tea.

[0003] In order to improve production efficiency, tea production is gradually becoming mechanized and automated, but there is still a big quality difference between mechanical production and manual production in some processes. In the process of breaking up tea leaves, high quality requirements and the breaking up of tea balls after repeated wrapping and kneading require manual breaking. The reason is that in the traditional drum-type breaking machine, the water content of the tea leaves is quickly lost during the rotation of the drum, and the quality cannot be guaranteed. In addition, the original shape of the tea leaves will be destroyed when the drum drives the tea leaves to roll. In comparison, manual operation is gentler and can better maintain the quality of the tea leaves.

[0004] However, manual operation is inefficient after all. Therefore, at this stage, it is necessary to improve the traditional tea breaking equipment to improve production efficiency while maintaining the quality of tea. To this end, this application provides a new tea breaking equipment to overcome the shortcomings of the existing technology. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a tea bagging and kneading machine. The mechanical breaking process not only easily causes the water loss of the tea leaves to be too fast, affecting the quality of the finished tea, but also destroys the already completed appearance shaping of the tea leaves.

[0006] The technical solution to the problem includes a cylinder with a vertical axis, a reciprocating mounting seat coaxially arranged in the cylinder, an electric telescopic rod coaxially fixed below the mounting seat, a first disc-shaped grille fixed to the upper end of the electric telescopic rod, a second disc-shaped grille spaced apart above the first grille, a third disc-shaped grille spaced apart above the second disc-shaped grille, the first disc-shaped grille, the second disc-shaped grille and the third disc-shaped grille fixed into a whole via a connecting rod, the whole is slidably mounted against the inner wall of the cylinder, the spacing of the third disc-shaped grille is greater than the spacing of the second disc-shaped grille and greater than the spacing of the first disc-shaped grille, a plurality of rotating shafts with inner ends tilted downward are evenly distributed on the inner circumference of the cylinder, the rotating shafts can reciprocate and the rotation directions of two adjacent rotating shafts are opposite, and a corrugated plate is provided above each rotating shaft along its length direction.

[0007] In order to realize the installation and feeding of the cylinder, three legs are evenly distributed on the circumference of the lower end of the cylinder, and a conical feeding hopper is installed on the upper end of the cylinder.

[0008] In order to achieve fixed installation and reciprocating rotation, a support rod is provided in the cylinder, a first motor is installed on the support rod, the output shaft of the first motor is fixedly connected to the mounting seat, and the first motor can reciprocate.

[0009] In order to realize the reciprocating drive of the electric push rod, the electric telescopic rod is a crank slider mechanism driven by the second motor.

[0010] In order to prevent tea leaves from being left on the upper end of the mounting seat, a conical sleeve is fixed to the lower end of the first disc-shaped grille. The lower end diameter of the conical sleeve is larger than the diameter of the mounting seat, and there is a gap between the conical sleeve and the inner wall of the cylinder.

[0011] In order to realize the gathering and discharging of tea leaves, a conical discharging hopper is provided at the lower end of the cylinder.

[0012] In order to drive the rotating shaft, the outer end of the rotating shaft passes through and extends out of the cylinder, and the rotating shaft and the cylinder are rotatably installed. A third motor is provided at the outer end of the rotating shaft, and the third motor is fixed to the outer side wall of the cylinder via an L-shaped rod. The output shaft of the third motor can rotate reciprocatingly.

[0013] In order to achieve opposite rotation directions of adjacent rotating shafts, the number of the rotating shafts is an even number, and the plurality of third motors are electrically controlled and linked via a PLC control unit.

[0014] The present invention has the following advantages: Advantages 1. This device is designed with two groups of breaking up devices for breaking up tea balls. The first group of breaking up devices includes: multiple inclined rotating shafts and conical supporting parts composed of corrugated plates. The tea balls are placed on the corrugated plates, and under the drive control of the third motor PLC control unit, the adjacent corrugated plates swing back and forth, breaking the supported tea balls into large pieces and dropping them. The second group of devices includes three disc-shaped grilles arranged at intervals up and down. The grid spacing of the three disc-shaped grilles decreases from top to bottom, and the disc-shaped grilles move up and down and reciprocate and rotate back and forth to achieve the large pieces of tea balls that fall down, and are graded step by step through the three groups of disc-shaped grilles until they are broken up.

[0015] Advantage 2: The materials of the whole breaking device are fed from the upper section and discharged from the lower section. The whole process is broken step by step by the gravity of the materials themselves and two groups of breaking units. The whole process is efficient and fast, which can effectively avoid the problem of excessive water loss caused by traditional drum breaking. Secondly, the reciprocating swing of the corrugated board breaks the tea ball from the lower end to break it up. The reciprocating vibration of the disc grille directly imitates the dispersion of handmade tea balls. The whole process will not cause the problem of breaking the already formed cuttings, ensuring the production requirements of high-end tea production and double-wrapping and kneading to protect the tea shape.

[0016] Advantage 3: Compared with traditional breaking equipment, this device is small in size, quick and easy to use, and the quality of the broken tea is high. It is suitable for the current production needs of small and medium-sized tea manufacturers and high-end industry manufacturers, and the production cost, use cost and maintenance cost are relatively low, and it can be promoted and applied on a large scale.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Example

[0025] Depend on Figures 1 to 5 It can be seen that the present invention includes a cylinder 1 with a vertical axis, a feed hopper 11 is installed at the upper end of the cylinder 1, a discharge hopper 15 is installed at the lower end, and a support leg 10 is installed at the lower end of the cylinder 1. A reciprocating mounting seat 2 is coaxially arranged in the cylinder 1, and the mounting seat 2 is driven by a first motor 13 fixed in the cylinder 1. The first motor 13 is a reciprocating step-rotating motor, and the rotation angle of the main shaft of the first motor 13 is within plus or minus 60 degrees, and the rotation speed is low. The first motor 13 is fixed in the cylinder 1 through a support rod 12, and the cross section of the support rod 12 is triangular. The support rod 12 with a triangular cross section can effectively prevent the accumulation of materials on the support.

[0026] An electric telescopic rod 3 is coaxially fixed below the mounting seat 2. The electric telescopic rod 3 is a crank slider mechanism driven by a second motor. The second motor is fixed on the mounting seat 2, and the fixing part of the crank slider is fixed on the mounting seat 2. A first disc-shaped grille 4 is fixed at the upper end of the electric telescopic rod 3. A second disc-shaped grille 5 is provided above the first grille, and a third disc-shaped grille 6 is provided above the second disc-shaped grille 5. The first disc-shaped grille 4, the second disc-shaped grille 5 and the third disc-shaped grille 6 are fixed into a whole through a connecting rod 7. The whole is slidably mounted against the inner wall of the cylinder 1, and the spacing of the third disc-shaped grille 6 is greater than the spacing of the second disc-shaped grille 5 and the spacing of the first disc-shaped grille 4. A conical sleeve 14 is fixed at the lower end of the first disc-shaped grille 4. The lower end diameter of the conical sleeve 14 is greater than the diameter of the mounting seat 2, and there is a gap between the conical sleeve 14 and the inner wall of the cylinder 1.

[0027] The inner circumference of the cylinder 1 is uniformly distributed with a plurality of rotating shafts 8 with inner ends tilted downward. The rotating shafts 8 can reciprocate and the rotation directions of two adjacent rotating shafts 8 are opposite. A corrugated plate 9 is provided above each rotating shaft 8 along its length direction. The outer end of the rotating shaft 8 penetrates and extends out of the cylinder 1. The rotating shaft 8 is rotatably mounted with the cylinder 1. The outer end of the rotating shaft 8 is provided with a third motor 16. The third motor 16 is fixed to the outer side wall of the cylinder 1 via an L-shaped rod. The output shaft of the third motor 16 can reciprocate. In order to realize that the adjacent rotating shafts 8 rotate in opposite directions, the number of the rotating shafts 8 is an even number, and the plurality of third motors 16 are electrically controlled and linked via a PLC control unit.

[0028] The specific working principle and process of the present invention are as follows: when the device is in use, the tea ball after wrapping and flat kneading is taken out from the cloth bag. At this time, the tea ball in this state is a spherical structure. The tea ball with this structure is placed on a conical supporting device composed of multiple corrugated plates 9. At this time, multiple third motors 16 are turned on. Under the control of the PLC control unit, the multiple third motors 16 realize the synchronous relative or opposite swinging of two adjacent corrugated plates 9 driven by the rotating shaft 8. At the same time, the first motor 13 and the second motor are turned on. Under the drive of the first motor 13 and the second motor, the mounting seat 2 is swung back and forth slowly, and the electric telescopic rod 3 is reciprocated and retracted at the same time. In this state, the first disc grille 4, the second disc grille 5 and the third disc grille 6 are reciprocated up and down and reciprocated. Swing.

[0029] The spherical tea ball is placed on a plurality of corrugated plates 9 for support, and the corrugated plates 9 are driven by the third motor 16 to swing. During this process, the corrugated plates 9 move the contact position of the spherical tea ball, and the large pieces of tea ball fall off under the action of the moving. As the corrugated plates 9 continue to move, the spherical tea ball is gradually decomposed into large pieces and falls off. This process simulates the process of manually decomposing the tea ball.

[0030] Under the action of the first disc-shaped grille 4, the second disc-shaped grille 5 and the third disc-shaped grille 6 that move up and down and swing back and forth, the large tea lumps are gradually thrown up and free-fall and then impacted by the grilles. The large tea lumps are gradually impacted into small pieces by the grilles, and fall to the lower grille through the upper grille with a larger grid pitch, and are repeatedly thrown up and free-fall and then impacted by the lower grille. Finally, the block tea leaves are separated into distinct pieces, and finally fall and are blocked by the conical sleeve 14, and are collected by the discharge hopper 15 on the material tray below. In this process, people manually shake the material to achieve the process of gradually dispersing the tea lumps.

[0031] It can be seen that the present invention completely simulates the manual operation of tea ball dispersion. The entire tea ball dispersion is simulated by the corrugated plate 9 simulating the manual operation of spreading the tea ball into blocks, and the three disc-shaped grids with reduced grid spacing simulate the manual operation of gradually shaking the blocks to disperse. The principle of the device comes from manual operation and perfectly restores the manual operation. In addition, the device is more efficient than manual operation, and the molding is performed from top to bottom, avoiding manual reciprocating dispersion, and the efficiency is increased several times. Example

[0032] On the basis of Example 1, the first motor 13 is cancelled, and only the second motor is used to realize the electric telescopic rod 3 to realize the up and down reciprocating vibration of the first disc grille 4, the second disc grille 5 and the third disc grille 6. This method can further reduce the cost of the device. At the same time, the tea leaves do not rotate in the cylinder 1, and the material will not be affected by the centrifugal force. The impact and filtering effect of the disc grille can be fully utilized. But at the same time, the risk of tea leaves blocking the grille will increase. It is worth noting that the rotation effect provided by the first motor 13 in Example 1 is a low-speed rotation in which the centrifugal force provided is negligible. The purpose of the rotation effect provided by the first motor 13 is to change the position of the material supplier's upward and downward impact, and avoid material blockage caused by the stacking of materials in one position.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
