Description

Technical Field

[0001] The present application relates to the technical field of rock tea processing, and in particular to a tea rolling machine. Background Art

[0002] Rock tea is a traditional Chinese tea with the fragrance of green tea and the sweetness of black tea. It belongs to the category of oolong tea. The processing of rock tea includes two stages: primary processing and refining. The primary processing includes picking, withering, airing, shaking, making, killing, rolling and drying. The refining process includes the steps of primary sorting, screening, re-sorting, winnowing, primary roasting, pile-leveling, re-roasting and fine tea. Every link needs to be strictly controlled to ensure the high quality of the final rock tea.

[0003] Among them, a tea rolling machine is usually used to roll rock tea. During the use of the existing tea rolling machine, the tea leaves to be rolled need to be placed in a rolling barrel first, and then a pressure device controls the pressing plate to apply a certain pressure to the tea leaves in the rolling barrel, and finally the tea rolling machine is started to make the rolling barrel move in a circle on the rolling plate to roll the tea leaves.

[0004] However, in the process of using the existing tea rolling machine, the operation process of loading, pressurizing and discharging tea leaves is relatively troublesome, which will affect the tea rolling efficiency.

[0005] Therefore, there is an urgent need for a tea kneading machine that can facilitate the operation of the staff. Utility Model Content

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-3 This application is described in further detail.

[0042] Reference Figure 1 The embodiment of the present application discloses a tea rolling machine for rolling tea leaves, comprising a frame 1, a rolling plate 2, a rolling barrel 3, a driving member 4 and a pressure device 5. The frame 1 is used as a mounting carrier for other structures; the rolling plate 2 is fixedly mounted on the top of the frame 1, and the tea leaves can be rolled by the rolling plate 2 when they move above the rolling plate 2; the rolling barrel 3 is movably mounted on the frame 1, and the rolling barrel 3 is located above the rolling plate 2, and the rolling barrel 3 can move in a circular motion relative to the frame 1 in a horizontal plane with the axis of the rolling plate 2 as the axis, and the tea leaves placed in the rolling barrel 3 can contact the rolling plate 2, and the tea leaves in the rolling barrel 3 are driven to move relative to the rolling plate 2 during the movement of the rolling barrel 3, thereby achieving rolling; the driving member 4 is fixedly mounted on the frame 1, and is used to provide power for the movement of the rolling barrel 3; the pressure device 5 is mounted on the rolling barrel 3, and is used to apply pressure to the tea leaves placed in the rolling barrel 3, so as to improve the contact effect between the tea leaves and the rolling plate 2, thereby improving the rolling effect of the tea leaves. In this embodiment, since the tea kneading machine is the prior art in this field, the frame 1, kneading plate 2, kneading barrel 3 and driving member 4 of the tea kneading machine are not described in detail, and the above structures are only briefly shown in the accompanying drawings.

[0043] Reference Figure 1 and Figure 2 The pressurizing device 5 includes a frame 51, a pressing plate 52, a pressurizing component 53, a pressure sensor 54 and a display 55. The frame 51 is used as a carrier of other structures of the pressurizing device 5; the pressing plate 52 is used to contact the tea leaves in the kneading barrel 3 and directly apply force to the tea leaves; the pressurizing component 53 is used to apply force to the pressing plate 52, so that the staff can control the pressure applied by the pressurizing device 5 to the tea leaves in the kneading barrel 3 according to the needs; the pressure sensor 54 is used in conjunction with the display 55, so that the staff can know the pressure applied by the pressurizing component 53 to the pressing plate 52 in real time while operating the pressurizing component 53.

[0044] The frame 51 includes a vertical rod 511 and a horizontal rod 512. The bottom of the vertical rod 511 is fixedly connected to the kneading barrel 3 and is located on one side of the barrel body of the kneading barrel 3, and the length direction of the vertical rod 511 is perpendicular to the axis of the kneading barrel 3. One end of the horizontal rod 512 in the length direction is rotatably connected to the top of the vertical rod 511, the length direction of the horizontal rod 512 is perpendicular to the length direction of the vertical rod 511, the rotation axis of the horizontal rod 512 is parallel to the length direction of the vertical rod 511, and the position of the horizontal rod 512 is higher than the top of the kneading barrel 3.

[0045] The pressing plate 52 includes a plate body 522 and a rod body 521. The plate body 522 is a circular plate-shaped structure, and the rod body 521 is a square rod-shaped structure. The rod body 521 is fixedly installed on one side of the axis direction of the plate body 522, and the axis of the rod body 521 coincides with the axis of the plate body 522.

[0046] The rod body 521 passes through the cross bar 512 and is slidably connected to the cross bar 512. The sliding direction of the rod body 521 is parallel to its own axial direction and the length direction of the vertical rod 511. The plate body 522 is located on the side of the cross bar 512 close to the kneading barrel 3, and the radial dimension of the plate body 522 is smaller than the radial dimension of the internal space of the kneading barrel 3.

[0047] The end of the rod 521 away from the plate 522 has a handle structure for the staff to control the sliding of the rod 521, and the handle structure is located on the side of the cross bar 512 away from the kneading barrel 3. When the rod 521 slides upward to the limit position, the plate 522 is at this time higher than the top of the kneading barrel 3, so that the staff can take out the kneaded tea leaves from the kneading barrel 3 or put the tea leaves to be kneaded into the kneading barrel 3.

[0048] Furthermore, in order to facilitate the staff to keep the plate body 522 at a position higher than the top of the kneading barrel 3, the pressing plate 52 also includes a positioning member 513.

[0049] The positioning member 513 is installed at a position of the rod 521 close to the plate 522 and is movably connected to the rod 521. In this embodiment, the positioning member 513 is preferably movably connected to the rod 521 in a sliding connection, and the sliding direction of the positioning member 513 is perpendicular to the axial direction of the rod 521.

[0050] The positioning member 513 can move in and out of one side of the rod body 521 during the sliding process relative to the rod body 521 . When the positioning member 513 slides to the extreme position in the direction close to the rod body 521 , the positioning member 513 can be completely located inside the rod body 521 .

[0051] When the plate body 522 is located inside the kneading barrel 3, the positioning piece 513 is located on the side of the cross bar 512 close to the kneading barrel 3; when the positioning piece 513 slides to the extreme position in the direction close to the rod body 521, the rod body 521 can slide upward to the extreme position, and the positioning piece 513 is located on the side of the cross bar 512 away from the kneading barrel 3; when the rod body 521 slides upward to the extreme position, the positioning piece 513 is controlled to move to the extreme position in the direction away from the rod body 521. After the staff releases the upward force applied to the pressure plate 52, the pressure plate 52 will move downward under the action of its own gravity until the positioning piece 513 and the cross bar 512 are against each other. At this time, the positioning piece 513 can limit the rod body 521 from continuing to slide downward, so that the plate body 522 remains in a state of being higher than the top of the kneading barrel 3.

[0052] During the rotation of the horizontal rod 512 relative to the vertical rod 511, there is a position state in which the plate body 522 is aligned with the internal space of the kneading barrel 3 along the sliding direction of the rod body 521. At this time, the plate body 522 can slide downward with the rod body 521 to enter the interior of the kneading barrel 3, so that it can contact the tea leaves in the kneading barrel 3 and apply pressure; there is also a position state in which the plate body 522 is located on one side of the space above the kneading barrel 3. At this time, there is no other structure above the kneading barrel 3 to affect, which can facilitate the staff to take out the rolled tea leaves in the kneading barrel 3 or put the rolled tea leaves into the kneading barrel 3.

[0053] Furthermore, in order to facilitate the staff to control the rotation of the horizontal rod 512 according to different usage requirements, it is preferred that the horizontal rod 512 has restrictions during the rotation relative to the vertical rod 511.

[0054] Reference Figure 1 and Figure 3 When the cross bar 512 rotates to the extreme position in the direction close to the kneading barrel 3, the axis of the plate 522 coincides with the axis of the kneading barrel 3, which makes it convenient for the plate 522 to slide downward with the rod 521 and enter the interior of the kneading barrel 3; when the cross bar 512 rotates to the extreme position in the direction away from the kneading barrel 3, the plate 522 is completely located on one side of the space above the kneading barrel 3, which further facilitates the staff to take out the rolled tea leaves in the kneading barrel 3 or put the rolled tea leaves into the kneading barrel 3.

[0055] Reference Figure 2 and Figure 3 Furthermore, in order to improve the position stability of the cross bar 512 when it is rotated to the extreme position in different directions and reduce the probability of the cross bar 512 being mistakenly rotated by external force and affecting normal use, the frame 51 also includes a locking component 514.

[0056] The locking assembly 514 is installed at the bottom of the cross bar 512 near the vertical bar 511, and includes a locking member 5141 and a second elastic member 5142. The locking member 5141 is movably connected to the cross bar 512. In this embodiment, the locking member 5141 is preferably movably connected to the cross bar 512 in a sliding connection direction, and the sliding direction of the locking member 5141 is preferably parallel to the length direction of the vertical bar 511.

[0057] The second elastic member 5142 is installed inside the crossbar 512, and the two ends of the second elastic member 5142 are respectively fixedly connected to the locking member 5141 and the crossbar 512, and the second elastic member 5142 has a tendency to drive the locking member 5141 to slide away from the crossbar 512. In this embodiment, the second elastic member 5142 is preferably a compression spring.

[0058] A boss structure is radially extended outward from the vertical rod 511 near the cross bar 512, and two locking grooves 5111 are formed on the top of the boss structure to match the structure of the end of the locking member 5141 away from the cross bar 512. In this embodiment, the end of the locking member 5141 away from the cross bar 512 preferably has a ball head structure.

[0059] When the cross bar 512 rotates to two extreme positions relative to the vertical bar 511, the locking member 5141 is aligned with the two locking grooves 5111 along its sliding direction, and the locking member 5141 can slide to the extreme position in the direction away from the cross bar 512 under the action of the second elastic member 5142, so that the end of the locking member 5141 away from the cross bar 512 is inserted into the corresponding locking groove 5111 to complete the locking. At this time, the relative position stability between the cross bar 512 and the vertical bar 511 is improved, and the staff needs to apply a certain amount of force to the cross bar 512 to drive the cross bar 512 to rotate relative to the vertical bar 511.

[0060] Reference Figure 1 and Figure 2 The pressurizing assembly 53 includes a pressurizing member 531 , a contact member 532 , a plurality of first elastic members 533 and a rotating member 534 .

[0061] The pressure member 531 and the abutment member 532 are both annular plate structures. A guide rod 5311 and a threaded rod 5312 extend outwardly along the axis direction of the pressure member 531 on one side of the axis direction of the pressure member 531. The guide rod 5311 and the threaded rod 5312 are symmetrically distributed on the pressure member 531 along the axis of the pressure member 531.

[0062] The pressure piece 531 is located on the side of the cross bar 512 close to the kneading barrel 3 and above the plate body 522. The guide rod 5311 is fitted with the cross bar 512. The threaded rod 5312 passes through the cross bar 512. The rod body 521 passes through the central hollow of the pressure piece 531, and the axis of the pressure piece 531 coincides with the axis of the plate body 522.

[0063] The rotating member 534 is mounted on the top of the cross bar 512 and is rotatably connected to the cross bar 512, and the rotation axis of the rotating member 534 is parallel to the rotation axis of the cross bar 512. The portion of the threaded rod 5312 that passes through the cross bar 512 also passes through the rotating member 534 and is threadedly engaged with the rotating member 534. At this time, by controlling the rotation of the rotating member 534, the pressure member 531 can be controlled to slide in a direction parallel to the sliding direction of the rod body 521.

[0064] The abutment member 532 is located on the side of the pressurizing member 531 close to the plate 522, and the axis of the abutment member 532 coincides with the axis of the pressurizing member 531. A plurality of first elastic members 533 are located between the abutment member 532 and the pressurizing member 531, the pressure sensor 54 is fixedly installed on the side of the abutment member 532 close to the pressurizing member 531, and the two ends of the first elastic member 533 are respectively fixedly connected to the pressurizing member 531 and the pressure sensor 54. In this embodiment, the first elastic member 533 is preferably a spring, and the pressurizing assembly 53 preferably includes a first elastic member 533, and the first elastic member 533 is sleeved and installed on the outside of the rod body 521.

[0065] The display 55 is fixedly mounted on the top of the crossbar 512, and the display 55 is connected to the pressure sensor 54 by signal, so that the pressure sensor 54 can reflect the sensed pressure in the form of data on the display 55. In this embodiment, since the pressure sensor 54, the display 55, and the structure of the pressure sensor 54 and the display 55 used in conjunction are all common prior arts, they are not described in detail here, and the pressure sensor 54 and the display 55 are only briefly shown in the drawings.

[0066] After the control guide slides toward the plate body 522, the abutment member 532 will directly contact the plate body 522, and the first elastic member 533 will also be compressed so that the pressure can be transmitted to the plate body 522 through the abutment member 532, thereby achieving the effect of the plate body 522 applying pressure to the tea leaves.

[0067] Furthermore, in order to facilitate the staff to control the sliding of the pressurizing member 531 , the pressurizing assembly 53 also includes an operating member 535 for controlling the rotation of the rotating member 534 .

[0068] The operating member 535 is also mounted on the top of the crossbar 512 and is rotatably connected to the crossbar 512. The operating member 535 is located on one side of the rotating member 534, and the rotation axis of the operating member 535 is parallel to the rotation axis of the rotating member 534. The peripheral side of the operating member 535 has a gear structure, and the peripheral side of the rotating member 534 also has a gear structure. The gear structure on the peripheral side of the operating member 535 meshes with the gear structure on the peripheral side of the rotating member 534, and the number of teeth of the gear structure on the peripheral side of the operating member 535 is less than the number of teeth of the gear structure on the peripheral side of the rotating member 534, so that the process of controlling the rotation of the operating member 535 to drive the rotating member 534 to rotate is more labor-saving. In this embodiment, it is preferred that the top of the operating member 535 also has a handle structure for the staff to control the rotation of the operating member 535.

[0069] Furthermore, in order to facilitate the pressure member 531 and the abutment member 532 to enter the interior of the kneading barrel 3 , it is preferred that the outer diameter of the pressure member 531 is equal to the outer diameter of the abutment member 532 , and both are smaller than the radial dimension of the interior of the kneading barrel 3 .

[0070] When the plate 522 contacts the tea leaves and the abutment 532 contacts the plate 522 , there is space between the plate 522 and the surrounding sides of the abutment 532 and the inner wall of the kneading barrel 3 , making it easy for the plate 522 , the abutment 532 and the pressure member 531 to enter the interior of the kneading barrel 3 .

[0071] The side of the abutment 532 close to the plate 522 is fixedly provided with a sealing ring 6 along its circumference, and the side of the plate 522 close to the abutment 532 has a guide surface 5221 along its circumference for the sealing ring 6 to contact. In this embodiment, the sealing ring 6 is preferably an elastic rubber product.

[0072] The guide surface 5221 is inclined relative to the axial direction of the plate body 522, and the guide surface 5221 is narrowed toward the direction close to the cross bar 512. When the abutment member 532 moves toward the direction close to the plate body 522, the sealing ring 6 will first contact the guide surface 5221, and the guide surface 5221 will guide the sealing ring 6 to deform and block the space between the plate body 522 and the inner wall of the kneading barrel 3, preventing the tea leaves under the plate body 522 from escaping through the above space during the kneading process.

[0073] The implementation principle of a tea rolling machine in the embodiment of the present application is:

[0074] After the operating member 535 is controlled to rotate so that the pressure member 531 slides upward to the limit position, the pressing plate 52 is controlled to slide upward to the limit position and positioned by the positioning member 513, and then the cross bar 512 is controlled to rotate to the limit position in the direction away from the kneading barrel 3, so that the staff can conveniently put the kneaded tea leaves into the kneading barrel 3 or take the kneaded tea leaves out of the kneading barrel 3;

[0075] After the tea leaves to be rolled are placed in the rolling barrel 3, first control the cross bar 512 to rotate to the extreme position in the direction close to the rolling barrel 3, then control the pressure plate 52 to slide downward so that the plate body 522 contacts the tea leaves, and then control the pressure member 531 to slide downward until the abutment member 532 contacts the plate body 522, then observe the data on the display 55 while continuing to control the pressure member 531 to slide downward until the data on the display 55 reaches the required pressure on the tea leaves, then the tea rolling machine can be driven to start and start rolling.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
