[0025] The present application will be further described in detail below in combination with the drawings and embodiments.

[0026] Embodiment 1

[0027] A tea leaf rolling device, as shown in Figures 1-6 , comprises a tea leaf placing roller 1 capable of rotating, the tea leaf placing roller 1 comprises a mesh-shaped side wall 101 capable of elastically deforming, the mesh-shaped side wall 101 is provided with a center roller 102 coaxially arranged with the tea leaf placing roller 1, and a tea leaf placing cavity 103 is formed between the outer wall of the center roller 102 and the inner wall of the mesh-shaped side wall 101.

[0028] The plurality of rubbing rollers 201 are capable of circumferential movement around the central roller 102 and extrude the meshed side wall 101 towards the central roller 102 during movement.

[0029] During the rubbing process, the plurality of rubbing rollers 201 rotate around the central roller 102 and extrude the meshed side wall 101, so that the tea leaves between the meshed side wall 101 and the central roller 102 are extruded and rubbed. Meanwhile, the tea leaf placing drum 1 can also rotate, thereby realizing the overturning of the tea leaves in the tea leaf placing drum 1 and achieving uniform rubbing in cooperation with the rubbing rollers 201.

[0030] In the embodiment, the rubbing roller mounting frame 2 is arranged outside the tea leaf placing drum 1. The rubbing roller mounting frame 2 comprises two disc end plates 202 and a plurality of mounting columns 203 arranged between the two disc end plates 202 and axially parallel to the central roller 102. The plurality of mounting columns 203 are uniformly arranged around the central roller 102, and the rubbing roller 201 is sleeved outside the mounting column 203 and is capable of rotating outside the mounting column 203. The rubbing roller 201 is connected to the rubbing roller mounting frame 2, so that the rubbing roller 201 outside the meshed side wall 101 rotates in the axial direction while self-rotating during the rubbing of the tea leaves in the tea leaf placing cavity 103, thereby further enhancing the rubbing effect.

[0031] In the embodiment, the tea leaf placing drum 1 further comprises drum end plates 104 arranged at both ends of the meshed side wall 101. The meshed side wall 101 is provided with a tea leaf inlet and outlet 107, and the tea leaf inlet and outlet 107 is provided with a closing door 106. The drum end plates 104 can support the meshed side wall 101. In the embodiment, the meshed side wall 101 can be an annular wall made of nylon rope or an annular wall made of other materials capable of elastic deformation, as long as it can elastically deform under the extrusion of the rubbing roller 201.

[0032] In addition, in order to realize the rotation of the tea leaf placing drum 1 and the rubbing roller mounting frame 2, a drum driving shaft 105 is arranged outside the drum end plate 104 and is used to drive the rotation of the tea leaf placing drum 1. A rubbing roller driving shaft 204 is arranged outside the disc end plate 202 and is used to drive the rotation of the rubbing roller mounting frame 2. A driving motor 4 is used to drive the rotation of the rubbing roller driving shaft 204, and a clutch mechanism 5 is used to realize the synchronous rotation of the drum driving shaft 105 and the rubbing roller driving shaft 204.

[0033] The motor shaft of the driving motor 4 is provided with an input pulley 401, and the outer part of the rubbing and twisting roller driving shaft 204 is provided with an output pulley 402. The input pulley 401 and the output pulley 402 are connected through a belt.

[0034] The clutch mechanism 5 in the embodiment comprises a slide column 501 coaxially arranged with the drum driving shaft 105. A push block 502 is sleeved on the slide column 501. A clamping piece 504 capable of retracting or extending radially along the drum driving shaft 105 is connected to the push block 502 through a connecting rod 503. A clamping groove 505 matched with the clamping piece 504 is arranged on the inner side wall of the rubbing and twisting roller driving shaft 204. A reset spring 506 is further arranged on the slide column 501. The reset spring 506 is used to drive the push block 502 to retract the clamping piece 504 through the connecting rod 503.

[0035] Further, a guide column 507 perpendicular to the slide column 501 is further connected to the slide column 501. The clamping piece 504 is arranged at the end of the guide column 507 away from the slide column 501, and the end of the clamping piece 504 towards the axis of the drum driving shaft 105 is provided with a sliding groove hole 508 capable of allowing the guide column 507 to extend into and slide.

[0036] During the rubbing and twisting process, the clutch mechanism 5 is first brought into a separated state. At this time, the push block 502 drives the clamping piece 504 to push out of the clamping groove 505 and retract into the drum driving shaft 105 through the connecting rod 503 under the action of the reset spring 506. At this time, the rubbing and twisting roller driving shaft 204 can rotate outside the drum driving shaft 105. The driving motor 4 drives the rubbing and twisting roller driving shaft 204 to rotate through the pulley, and then drives the rubbing and twisting roller mounting frame 2 to rotate, so as to rotate the plurality of rubbing and twisting rollers 201 relative to the center roller 102, and press the meshed side wall 101 towards the center roller 102 during the rotation process, so as to realize the rubbing and twisting of the tea leaves in the tea placing cavity 103 through the cooperation of the rubbing and twisting rollers 201 and the center roller 102.

[0037] When the rubbing and twisting is performed for a period of time, the clutch mechanism 5 is brought into a closed state. The push block 502 is pushed to press the reset spring 506. The push block 502 drives the clamping piece 504 to move towards the clamping groove 505 through the connecting rod 503, and finally clamps into the clamping groove 505. At this time, the rubbing and twisting roller driving shaft 204 forms an integral whole with the drum driving shaft 105. The driving motor 4 drives the rubbing and twisting roller driving shaft 204 to rotate through the pulley, and simultaneously drives the drum driving shaft 105 to rotate synchronously, and then realizes the synchronous rotation of the rubbing and twisting roller mounting frame 2 and the tea placing drum 1. At this time, the tea placing drum 1 realizes the overturning of the tea leaves inside, so as to realize more uniform rubbing and twisting.

[0038] The embodiment also comprises a clutch driving mechanism 6, the clutch driving mechanism 6 comprises a push rod 601 for pushing the push block 502 to move axially along the slide column 501, one end of the push rod 601 is sleeved outside the slide column 501, and the other end is connected with a driving cylinder 602 through a spring damping mechanism 3.

[0039] The spring damping mechanism 3 comprises a push rod connecting plate 603 and a piston rod connecting plate 604 connected with the push rod 601 and the piston rod of the driving cylinder 602 respectively, the push rod connecting plate 603 and the piston rod connecting plate 604 are provided with a spring column 605 fixed at one end on the piston rod connecting plate 604 and capable of penetrating out of the push rod connecting plate 603 at the other end, and the spring column 605 is sleeved with a damping spring 606 abutting against the push rod connecting plate 603 and the piston rod connecting plate 604 at two ends.

[0040] During the driving process, the driving cylinder 602 does not directly act on the push block 502, but pushes the push block 502 through the spring damping mechanism 3, so that the force of the driving cylinder 602 is converted into the pushing of the push rod 601 by the damping spring 606 through the push rod connecting plate 603. The flexible force transmission can make the driving of the clutch mechanism 5 more stable, and reduce the damage rate of the clutch mechanism 5 to a certain extent.

[0041] It is easy to understand that the skilled in the art can obtain other embodiments by combining, splitting, recombining and the like of the embodiments of the present application on the basis of one or more embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0042] In summary, the above only describes the preferred embodiments of the present application, and any changes and modifications made within the scope of the present application shall be covered by the present application.
