Description

Technical Field

[0001] The invention relates to the technical field of tea processing, in particular to a tea leaf shaking machine. Background Art

[0002] Shaking tea leaves can enhance the transport function of leaf tip tissue and coordinate the flavoring substances of tea soup, which has an intrinsic effect. At the same time, mechanical friction can cause damage to leaf cells, causing enzymatic oxidation of tea polyphenols and inducing aroma, which has an extrinsic effect. Currently, there are two types of shaking tea leaves: manual and mechanical. Manual shaking generally uses a water sieve. Mechanical shaking is mainly divided into shaking machines that imitate manual shaking, such as CN207011626U, a tea shaking machine; and shaking machines that use rollers, such as CN107136237A, a shaking machine and a method for shaking tea leaves.

[0003] At present, in order to improve efficiency, a drum-type tea-shaking machine is generally used. However, the drum-type tea-shaking machine needs to open the lid every time to add and remove tea leaves; it is not convenient for continuous production. To solve this problem, tea-shaking equipment capable of continuous production has appeared on the market, such as CN114009534A, a tea-shaking machine, which uses a built-in transfer hopper to pull and load materials, but the equipment is relatively long, occupies a large space, and requires more auxiliary equipment to take and put tea leaves; another example is CN113207975A, a drum-type continuous tea-shaking machine, which has guide blades at both ends of the drum, and uses tilting to achieve tea pouring; its biggest problem is that it cannot ensure that the tea leaves are completely poured out, and the second is that the pouring speed is slow, and the drum installation problem caused by tilting is not easy to solve, and the equipment is easy to damage.

[0004] In addition, the basic principle of "slow first and fast later" should be followed when shaking the green tea. Traditional equipment requires frequent and regular changes in speed, which is inconvenient to operate. In summary, a green tea shaking equipment is currently needed to solve the problem of continuous production. Summary of the invention

[0005] In view of the above situation, in order to solve the problems existing in the prior art, the purpose of the present invention is to provide a tea shaking machine that can effectively solve the problems of changing shaking speed requirements and inability to perform continuous production.

[0006] The technical solution is to include a base, on which are installed from left to right a plurality of rollers of the same diameter, with clearances between the plurality of rollers being matched; each roller can rotate independently, and the rotation speed of the rollers increases successively from left to right; each of the rollers is divided into one or more upper compartments, and the width of each upper compartment of the plurality of rollers is the same; each of the rollers is installed with an arc hopper, which can move left and right, and is divided into one or more lower compartments corresponding to the upper compartments in the roller, and the upper and lower compartments corresponding to each other form a chamber; a discharge port is provided at the bottom of the rightmost lower compartment in the rightmost arc hopper; a feeding hopper is fixed at the left end of the leftmost arc hopper; an upper compartment is provided in the feeding hopper; the feeding hopper and the plurality of arc hoppers can move left and right synchronously, and realize the staggered correspondence and reset of the upper compartments and the lower compartments; a feeding electric cylinder is provided at the left end of the base; and a reset electric cylinder is provided above the right end of the base.

[0007] Preferably, an upper magnet is fixed on the middle side wall of each upper compartment; a lower magnet corresponding to the upper magnet is arranged on the middle side wall of each lower compartment, and the upper magnet and the lower magnet can be attracted to each other.

[0008] Preferably, a transverse support shaft is provided on the base, the support shaft passes through the plurality of rollers, and the rollers are rotatably connected to the support shaft.

[0009] Preferably, the base is provided with a plurality of supporting wheels corresponding to the roller, the base is provided with a stepping motor, the roller is sleeved with a pulley, and the output wheel of the stepping motor drives the pulley to rotate via a belt.

[0015] 2. This equipment can realize small batch shaking of tea leaves and continuous feeding through the cooperation of multi-section drum 2 and multi-section hopper; when shaking small batches, the tea leaves are more easily turned over, which can avoid the problem that when shaking large batches, the outer tea leaves continue to contact with the wall of drum 2 and the inner tea leaves are always wrapped in it.

[0023] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings. Example

[0024] This embodiment provides a tea leaf shaking machine, including a base 1, on which a horizontal support shaft 12 is provided, the support shaft 12 is fixed and does not rotate, and three rollers 2 are rotatably mounted on the support shaft 12. The connection between the support shaft 12 and the roller 2 can be rotatably mounted through a tapered roller bearing to achieve positioning and support of the roller 2. A gap is left between two adjacent rollers 2; each roller 2 can rotate independently, and the rotation speed of the roller 2 increases from left to right; that is, the left side is a low-speed roller 2, the middle is a medium-speed roller 2, and the right side is a high-speed roller 2.

[0025] There are fan-shaped baffles on the left and right sides of each drum 2, and an arc hopper 3 is inserted under the drum 2. After the arc hopper 3 is inserted into the drum 2, a complete chamber is formed. There is only one chamber inside the left drum 2, and a middle partition is set in the middle position of the middle drum 2 and the right drum 2, and a middle partition is also set in the middle of the corresponding arc hopper 3; so that two chambers are formed inside the middle drum 2 and the right drum 2. And the width of all the chambers is the same.

[0026] In summary, the volume inside the low-speed drum 2 is V, and the volumes inside the medium-speed drum 2 and the high-speed drum 2 are 2V.

[0027] In some embodiments, the volume of the three drums 2 can be customized to any integer multiple of V according to actual needs, or increased to four or five drums 2, and the speed increases from left to right, so that the tea leaves can go through a shaking process from slow to fast.

[0028] The bottom of the lower compartment 5 on the rightmost side of the rightmost arc hopper 3 is provided with a discharge port 6; a hopper 7 is fixed to the left end of the leftmost arc hopper 3; a feeding electric cylinder 8 is provided at the left end of the base 1; and a reset electric cylinder 9 is provided above the right end of the base 1. The feeding electric cylinder 8 can push the hopper 7 to the right by a distance L of the hopper 7. As a result, all arc hoppers 3 move to the right by L, so that the bottom space of the originally formed chamber is synchronously moved to the right by one station; that is, the lower compartment 5 moves to the right by L. The rightward feeding of the tea leaves in the chamber is realized. The tea leaves on the rightmost side will move to the right side of the entire drum 2 and flow out from the discharge port 6. The tea leaves to be processed will enter the first chamber on the far side from the position of the feeding hopper 7.

[0029] Then, by rotating 180 degrees, the resetting electric cylinder 9 pushes the arc hopper 3 to the left, thereby resetting the arc hopper 3 and completing the feeding of tea leaves.

[0030] In some embodiments, in order to avoid the arc hopper 3 from being out of position and causing the rotation to be stuck, an upper magnet 10 is fixed on the middle side wall of each upper compartment 4; a lower magnet 11 corresponding to the upper magnet 10 is arranged on the middle side wall of each lower compartment 5, and the upper magnet 10 and the lower magnet 11 can be attracted to each other. That is, after the arc hopper 3 is moved, the slight misalignment can be automatically corrected by the attraction of the magnet, reducing the dependence on processing and installation accuracy.

[0031] In some embodiments, a plurality of supporting wheels 13 corresponding to the drum 2 are provided on the base 1, a stepper motor 14 is provided on the base 1, a pulley is provided on the outer surface of the drum 2, and the output wheel of the stepper motor 14 drives the pulley to rotate via a belt.

[0032] In some embodiments, the base 1 is provided with a plurality of supporting wheels 13 corresponding to the drum 2, the base 1 is provided with a stepping motor 14, the drum 2 is provided with a gear ring outside, and the gear ring is driven by the stepping motor 14. The positioning accuracy of the drum 2 after rotation can be improved.

[0033] In some embodiments, the outer wall of the drum 2 and the outer wall of the hopper are both made of bamboo, which facilitates the dissipation of moisture in the tea leaves.

[0034] In some embodiments, the outer wall of the drum 2 and the outer wall of the hopper are made of metal and are densely covered with ventilation holes, so as to facilitate the dissipation of moisture in the tea leaves and improve the structural strength. Example

[0035] This embodiment provides a method for using a tea leaf shaking machine. In a tea leaf shaking machine, the stepper motor 14, the feed cylinder 8 and the reset cylinder 9 are all controlled by a controller and are programmed to perform the following specific working steps.

[0036] Step 1: All rollers 2 are in the initial position, that is, the arc hopper 3 is in the position directly below. The tea leaves to be processed are added into the feeding hopper 7 by means of a conveyor belt, see the attached Figure 6 .a.

[0037] Step 2: The feed cylinder 8 moves to the right and then resets, so that the feed hopper enters the first chamber on the left; at the same time, all the arc hoppers 3 also move to the right by a chamber, see the attached Figure 6 .b. At this time, the tea leaves in the original chamber will be fed to the next chamber to the right, and the tea leaves in the rightmost chamber will flow out from the discharge port 6.

[0038] Step 3: All rollers 2 rotate 180 degrees synchronously, and the arc hopper 3 moves to the top. Figure 6 .c. At this time, the tea leaves after feeding will rotate into the upper compartment 4 of the drum 2, providing space for the subsequent reset of the arc hopper 3.

[0039] Step 4: The reset electric cylinder 9 moves to the left and then resets, so that the arc hopper 3 and the feeding hopper 7 are reset. Figure 6 .d.

[0040] In the fifth step, the three rollers 2 rotate at low, medium and high speeds respectively to shake the green onion.

[0041] Repeat the above steps.

[0042] Through the above steps, tea leaves can be fully shaken in small batches from left to right through three different speeds of the drum 2, low, medium and high. Frequent speed adjustment is not required. At the same time, the number of different chambers can be customized in each stage, that is, the time length of each stage can be controlled as needed. Thus, the process requirements can be better met.

[0043] By shaking the tea leaves in small batches, the entire device has a lightweight structure, occupies little space, and is easy to operate continuously. There is no need to wait for a long time to complete the shaking, but the tea leaves can be processed in batches more quickly, which can better coordinate with the previous and subsequent processing flows.

[0044] By shaking the tea leaves in small batches, it is also possible to avoid the accumulation of tea leaves, which may lead to excess tea leaves in some areas and the problem of the tea leaves wrapped inside not being able to be fully shaken.

[0045] By using the arc hopper 3, the tea leaves in each stage can be completely fed to the next stage to avoid residue. In addition, the edges of the arc hopper 3 can also provide a certain resistance for the turning of the tea leaves when shaking the tea leaves to avoid the inertial flow of the tea leaves, thereby improving the turning efficiency of the tea leaves.
