Description

Technical Field

[0001] This utility model relates to the field of circular tea rolling technology, specifically to a circular tea rolling mechanism and a circular tea rolling device. Background Technology

[0002] Ring tea is tea made by rolling tea leaves into a ring shape. Currently, tea leaves are mainly processed into rings by hand. Operators use rollers to flatten the tea leaves and then roll and wrap them with their hands.

[0003] CN210226780U discloses a Yuhuan tea processing device. Before the device is in operation, the port of the machine-wrapping needle is pushed against the follower sealing ring, so that the port is blocked and air cannot enter the machine-wrapping needle from the port, but can only enter from the side hole. The air inside the machine-wrapping needle is continuously drawn in by the vacuum pump. When the flattened bud strip approaches the side hole of the machine-wrapping needle, the bud strip will be adsorbed on the machine-wrapping needle. The motor set on the worktable drives the pulley to rotate, which in turn drives the machine-wrapping needle to rotate, so that the bud strip is curled into the shape of a ring tea.

[0004] During the wrapping process, because the equipment uses a method of sucking on one end of the bud to wrap the tea in a ring shape, the pre-flattened bud will have some debris, which can easily clog the suction holes of the wrapping needle. Therefore, a new ring-shaped tea rolling equipment is needed. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a ring-shaped tea rolling mechanism and a ring-shaped tea rolling device. By clamping and rotating the tea leaves to roll them into a ring, the problem of clogging the suction holes caused by adsorption during rolling can be effectively avoided. At the same time, the tea leaves are in a side-standing state during rolling, and the flattened tea leaf head is not affected by gravity, making it easier to place in the designated position, thereby improving rolling efficiency.

[0006] Specifically, this utility model is implemented as follows:

[0007] A circular tea-rolling mechanism, comprising:

[0008] The needles are wrapped and arranged vertically.

[0009] The clamping mechanism is configured to move toward / away from the wrapping needle to clamp or release the tea leaves together with the wrapping needle.

[0010] A limiting mechanism is located on one side of the wrapping needle. When wrapping tea, the limiting mechanism and the wrapping needle form a curling channel to guide the tea leaves to curl.

[0011] The wrapping needle and clamping mechanism are configured to rotate around the axis of the wrapping needle, so as to drive the tea leaves that are jointly clamped to rotate around the axis of the wrapping needle, so as to wrap the tea leaves into a ring shape.

[0012] Further, the clamping mechanism includes:

[0013] A needle clamp configured to move in the direction towards / away from the needle wrapping;

[0014] The needle wrapping is disposed within a rotating shaft. The rotating shaft is connected to the workbench through a bearing block. The top of the rotating shaft is fixedly connected to a rotating disk. The needle wrapping rotates along with the rotation of the rotating shaft;

[0015] A needle clamp receiving groove is provided on the outer surface of the rotating shaft. The needle clamp is placed within the needle clamp receiving groove;

[0016] A needle clamp opening / closing driving member is provided on one side of the needle clamp.

[0017] Further, an elastic member cavity is provided within the needle clamp receiving groove at the position of the bearing block. An elastic member is provided within the elastic member cavity. One end of the elastic member is connected to the inner ring of the bearing block, and the other end is connected to the needle clamp. When the needle clamp opening / closing driving member pushes the needle clamp, the needle clamp compresses the elastic member and moves away from the needle wrapping, being in an open state.

[0018] Further, the needle wrapping is configured to move along the axial direction of the rotating shaft. The lower part of the needle wrapping penetrates through the rotating shaft and is connected to a rotation driving member. The rotation driving member is used to drive the rotation of the rotating shaft;

[0019] A bracket is provided at the lower part of the needle wrapping. The bracket is in a "C" shape. A needle clamp limiting block is provided at the upper part of the bracket. A needle clamp limiting groove is provided at the corresponding position of the needle clamp. The needle clamp limiting block is placed within the needle clamp limiting groove;

[0020] A lifting driving member is provided at the lower part of the bracket. The lifting driving member is used to drive the lifting of the bracket to带动 the needle wrapping and the needle clamp to move in the vertical direction.

[0021] Further, a needle wrapping limiting groove is provided within the rotating shaft. A needle wrapping limiting block is provided on the needle wrapping. The needle wrapping limiting block is placed within the needle wrapping limiting groove so that when the needle wrapping rotates, it带动 the rotation of the rotating shaft.

[0022] Further, the rotation driving member is传动连接 to the needle wrapping through a reduction gearbox. The needle clamp deflects α degrees horizontally;

[0023] A transmission shaft is provided within the reduction gearbox. Both ends of the transmission shaft penetrate through the reduction gearbox. A rotation control block is provided at one end, and a positioning block is provided at the other end. A notch is provided on the rotation control block. A first microswitch is provided on one side of the rotation control block;

[0024] The positioning block is provided with a protrusion, and a positioning rod is provided on one side of the positioning block. The positioning rod is connected to a positioning rod driving component, and the positioning rod driving component is used to drive the positioning rod to move radially along the positioning block.

[0025] When the roller of the first micro switch is located within the notch, the positioning rod drive stops.

[0026] Furthermore, the limiting mechanism includes:

[0027] A limiting roller is located on one side of the wrapping needle and is configured to move toward / away from the wrapping needle;

[0028] A straightening board is positioned above the wrapping needle and is configured to move vertically. A tea-wrapping trough is provided at the corresponding position of the straightening board and the wrapping needle. When wrapping tea, the straightening board is in a low position to restrict the vertical position of the tea leaves.

[0029] Furthermore, a second micro switch is provided at the end of the straightening plate away from the wrapping needle. The second micro switch is connected to the positioning rod drive. When the straightening plate is in a low position, the roller of the second micro switch is pushed by the straightening plate, and the second micro switch is in the position of connecting the positioning rod drive, driving the positioning rod to retract.

[0030] The workbench is equipped with a proximity switch, which is used to detect when a person's hand enters or leaves the tea-wrapping work area.

[0031] Furthermore, this utility model also provides a ring-shaped tea rolling device, including a workbench, a discharging mechanism, and the ring-shaped tea rolling mechanism as described above. The workbench is provided with a discharging mechanism and a discharging port, which are arranged opposite to each other. After the ring-shaped tea rolling mechanism rolls the tea leaves into a ring, the discharging mechanism pushes the rolled ring-shaped tea leaves out of the discharging port.

[0032] The working principle of this utility model:

[0033] During rolling, the tea leaves are manually placed at the wrapping needle, with the leaves standing upright. The clamping needle of the holding mechanism moves to the wrapping needle and, together with the wrapping needle, clamps the tea leaves. During the placement of the tea leaves, because the flattened leaves are quite thin (generally only a few tenths of a millimeter thick), in existing technology, the annular tea axis is horizontal, and the leaves are placed horizontally. The head of the leaves is easily affected by gravity, causing it to droop, making it difficult to place the leaves into the designated slots and resulting in low efficiency. Therefore, in this application, the annular tea axis is vertical, and the tea leaves are placed upright. In this state, the head of the leaves is not affected by gravity and will not droop, thus facilitating the placement of the tea leaves and effectively improving rolling efficiency.

[0034] After the tea leaves are clamped, the limiting mechanism restricts their movement. When the clamping needle and wrapping needle rotate, they cause the tea leaves to rotate. Under the guidance and limiting action of the limiting mechanism, the tea leaves curl into a ring, forming a ring-shaped tea.

[0035] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0036] (1) The annular tea rolling mechanism provided by this utility model can effectively solve the problem of debris clogging the needle suction hole under negative pressure adsorption in the prior art.

[0037] (2) The wrapping needles are arranged vertically, which changes the tea leaves to a side-standing position, making it easier to quickly place the tea leaves in the designated position and helping to improve the rolling efficiency.

[0038] (3) The existing equipment can only be used for buds, while the equipment in this utility model has a vertically arranged wrapping needle and is limited by a limiting mechanism, which can realize the rolling of "Y" shaped tea leaves. It has a wider range of applications and can effectively save the leaf picking process when tea farmers pick tea. Attached Figure Description

Detailed Implementation

[0058] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0059] Example 1

[0060] like Figure 1-4As shown, this embodiment provides a ring-shaped tea rolling device, including: a worktable 1, a wrapping needle 2, a clamping mechanism, a limiting mechanism, and a discharging mechanism. The limiting mechanism and the discharging mechanism are located on the worktable 1. A discharging port is provided at a position opposite to the discharging mechanism, and a device below the discharging port is designed to collect the tea leaves 8 rolled into a ring. The limiting mechanism, the discharging mechanism, and the discharging port are arranged in a "cross" shape, with the wrapping needle 2 and the clamping mechanism in the middle, which is the tea rolling work area. The tea leaves 8 are manually placed in by the worker and moved towards the wrapping needle 2 by the clamping mechanism, where they are clamped together. Then, the limiting mechanism actuates to guide and limit the tea leaves 8, causing the wrapping needle 2 to rotate and form a ring-shaped tea 81. After the tea leaves 8 are rolled into a ring-shaped tea 81, the limiting mechanism resets, the wrapping needle 2 and the clamping mechanism descend, and the discharging mechanism actuates to push the ring-shaped tea 81 out of the discharging port.

[0061] Specifically, such as Figure 5-7 As shown, the power drive unit is located below the workbench 1, including an air source, a rotary motor 21, and a reduction gearbox 24. Each drive cylinder of the equipment is connected to the air source. The rotary motor 21 is connected to the reduction gearbox 24 via a pulley 25. The upper part of the reduction gearbox 24 is an output shaft 241, which is connected to the wrapping needle 2. When the rotary motor 21 rotates, it drives the wrapping needle 2 to rotate synchronously through the output shaft 241, thus realizing the tea wrapping action. The wrapping needle 2 has a two-section structure. The lower section has a larger diameter to provide sufficient strength and can also serve as a limit for the upward movement of the wrapping needle 2. The upper section of the wrapping needle 2 has a smaller diameter and passes through the rotating shaft 22 and the rotating disk 13 on the workbench 1. The rotating shaft 22 is fixed to the bottom of the workbench panel via two bearing seats 23 distributed vertically. A needle-wrapping limiting groove 221 is provided at the lower part of the rotating shaft 22, and an output shaft limiting groove 243 is provided at the top of the output shaft 241. A needle-wrapping limiting block 29 is provided at the corresponding position of the wrapped needle 2. Through the cooperation of the needle-wrapping limiting groove 221, the output shaft limiting groove 243 and the needle-wrapping limiting block 29, the output shaft 241, the wrapped needle 2 and the rotating shaft 22 can be rotated synchronously without affecting the lifting and lowering of the wrapped needle 2. A bracket 5 is provided on the wrapped needle 2. A needle-clamping limiting block 53 is provided at the upper part of the bracket 5 and a connecting block 52 is provided at the lower part, forming a "U"-shaped structure. The connecting block 52 is fixedly connected to the lower part of the wrapped needle 2. The needle-clamping limiting block 53 is movably sleeved on the rotating shaft 22. A lifting cylinder 51 is provided at the bottom of the bracket 5. The lifting cylinder 51 is fixed to the top of the reduction gearbox 24. With the reduction gearbox 24 as support, the bracket 5 drives the wrapped needle 2 to lift and lower.

[0062] The clamping mechanism includes a clamping needle 3 and a clamping needle opening and closing cylinder 34 for driving the clamping needle 3 to open and close. A vertical clamping needle receiving groove 223 is provided on the outer surface of the rotating shaft 22, and the clamping needle 3 is placed in the clamping needle receiving groove 223. The clamping needle 3 has an "F" shaped structure and a clamping needle limiting groove 31 is provided on it. The clamping needle limiting groove 31 is adapted to the clamping needle limiting block 53 on the bracket 5, forming a structure in which the clamping needle 3 is driven to move up and down by the clamping needle limiting block 53. The clamping needle limiting block 53 is located below the upper bearing seat 23. An elastic element cavity is provided at the overlapping position of the clamping needle receiving groove 31 and the upper bearing seat 23. A spring 32 is provided in the elastic element cavity. One end of the spring 32 abuts against the inner ring of the bearing in the bearing seat 23, which abuts against the clamping needle 3. A clamping needle opening and closing cylinder 34 is provided in the horizontal direction of the bracket 5. A push plate 35 is provided at the output end of the clamping needle opening and closing cylinder 34, and the push plate 35 corresponds to the bottom of the clamping needle 3. The rotating disk 13 is provided with a needle-moving hole in the radial direction for the needle 3 to move. When the device is in use, the worker is located at the baffle 11 of the workbench 1. In order to facilitate the worker to place the tea leaves 8, the needle-moving hole and the needle 3 are arranged in a way that deflects laterally by α degrees (0≤α≤90°, α=45° in this embodiment).

[0063] like Figure 8 As shown, when the push plate 35 is pushed out, it pushes the lower part of the clamping needle 3, causing the clamping needle 3 to swing around the support part 33 as the fulcrum, thereby causing the top of the clamping needle 3 to move and open along the clamping needle moving hole. At the same time as the clamping needle 3 opens, the spring 32 is compressed. When the push plate 35 is retracted, the upper part of the clamping needle 3 is closed under the action of the spring 32's rebound force, and together with the wrapping needle 2, it clamps the tea leaves 8.

[0064] A limiting mechanism is installed on the workbench 1, and includes a limiting roller 41 and a straightening plate 42. The limiting roller 41 is horizontally arranged on the workbench 1 and faces the wrapping needle 2. It is driven by a limiting roller cylinder 44 to move closer to or away from the wrapping needle 2. The straightening plate 42 is located on the opposite side of the limiting roller 41 and is installed on the vertical plate of the workbench 1. It is driven to move up and down by a straightening plate cylinder 45.

[0065] A drive shaft 242 is provided on the reduction gearbox 24, and the output shaft 241 is connected to the drive shaft 242. Both ends of the drive shaft 242 extend out of the reduction gearbox 24. A rotation control block 27 is provided at one end, and a positioning block 26 is provided at the other end. A protrusion 261 is provided on the positioning block 26, and a positioning rod 28 is provided on one side of the positioning block 26. The positioning rod 28 is connected to the positioning rod cylinder 281 through a linkage mechanism 283. A third micro switch 282 is provided on one side of the linkage mechanism 283. The positioning rod cylinder 281 drives the positioning rod 28 to move radially along the positioning block 26. By blocking the protrusion 261, the rotation angle of the rotating shaft 22 and the clamping needle 3 is positioned, so that the clamping needle 3 can stop at the position of lateral deflection α degrees. Figure 9As shown, the rotation control block 27 has a notch 271. A first micro switch 272 is provided on one side of the rotation control block 27, and a second micro switch 43 is arranged on the side of the straightening plate 42 away from the wrapping needle 2. The second micro switch 43 is fixed on the worktable 1. When the straightening plate 42 is pressed down, it pushes the roller of the second micro switch 43. At this time, the positioning rod cylinder 281 is activated. When the positioning rod cylinder 281 drives the positioning rod 28 to retract, the obstruction of the positioning rod 28 on the protrusion 261 and the positioning block 26 is released, and the rotation motor 21 can rotate. When the positioning rod 28 retracts, the linkage mechanism 283 presses the button of the third micro switch 282. The third micro switch 282 is connected to the rotation motor 21, activating the rotation motor 21 and causing the rotation motor 21 to rotate the angle of the protrusion of the rotation control block 27. When the roller falls into the notch 271, the rotation motor 21 is deactivated, realizing the power-off control of the rotation motor 21. The extension of the positioning rod 28 is achieved by a time delay. That is, the positioning rod cylinder 281 is connected to the time delay relay. After the positioning rod cylinder 281 is turned on, it will automatically extend after a certain time delay, restoring the positioning rod 28's obstruction of the protrusion 261, so that the clamping pin 3 can stop at the position with a lateral deflection of α degrees.

[0066] A proximity switch 7 is installed on the workbench 1. The proximity switch 7 is located on the feeding side of the workbench 1 and is used to detect the entry and exit of a person's hand in the tea-wrapping work area. The discharging mechanism includes a discharging cylinder 61 and a discharging plate 6 at the output end of the discharging cylinder 61. The discharging plate 6 is arc-shaped and is used to push the rolled annular tea 81 out of the discharging port.

[0067] like Figure 10-17As shown, during tea wrapping, the worker places the tea leaves 8 between the wrapping needle 2 and the clamping needle 3. The proximity switch 7 is triggered, activating the clamping needle opening / closing cylinder 34, which drives the push plate 35 to retract. Under the restoring force of the spring 32, the clamping needle 3 closes, clamping the tea leaves 8 together with the wrapping needle 2. After the proximity switch 7 detects that the worker's hand has left the tea wrapping area, it activates the limiting roller cylinder 44 and the straightening plate cylinder 45, causing the limiting roller 41 and the straightening plate 42 to limit the tea leaves 8, forming a curling channel between the limiting rollers 41 and 42 to guide the tea leaves to curl. After the straightening plate 42 is in place, it presses the roller of the second micro switch 43. At this time, the positioning rod cylinder 281 is activated. When the positioning rod cylinder 281 drives the positioning rod 28 to retract, it releases the obstruction of the positioning rod 28 on the protrusion 261 and the positioning block 26, allowing the rotary motor 21 to rotate. When the positioning rod 28 retracts, the linkage mechanism 283 presses the button of the third micro switch 282. The third micro switch 282 is connected to the rotary motor 21, turning on the rotary motor 21. The rotary motor 21 drives the wrapping needle 2 to rotate through the output shaft 241 of the reduction gearbox 24, and at the same time drives the rotating shaft 22 and the clamping needle 3 on it to rotate synchronously. Under the guiding and limiting action of the limiting roller 41 and the straightening plate 42, the tea wrapping action is realized. The rotation angle of the rotary motor 21 is the angle of the protrusion of the rotation control block 27. When the roller of the first micro switch 272 falls into the notch 271, the rotary motor 21 is disconnected, the positioning rod 28 is reset, and the protrusion 261 is blocked to avoid the problem of inaccurate positioning of the clamping needle 3 under the action of inertia, so that the clamping needle 3 can stop at the position of lateral deflection α degrees. After the tea leaves 8 are wrapped to form a ring-shaped tea 81, the limiting roller 41 and the straightening plate 42 are reset. At the same time, the lifting cylinder 51 drives the wrapping needle 2 and the clamping needle 3 to descend through the bracket 5. Then, the discharge cylinder 61 drives the discharge plate 6 to push forward, pushing the ring-shaped tea 81 out of the discharge port. After the discharge plate 6 is reset, the lifting cylinder 51 drives the wrapping needle 2 and the clamping needle 3 to rise. The clamping needle opening and closing cylinder 34 drives the push plate 35 to push forward, opening the clamping needle 3 for the next tea wrapping.
