Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubbing and twisting machine, in particular to a rubbing and twisting machine with multiple rubbing and twisting processes. BACKGROUND

[0002] The tea culture has accompanied us for thousands of years, and tea leaves need to go through multiple tea making processes from picking to packaging and selling. Rubbing and twisting is one of the tea making processes. Rubbing and twisting mainly makes tea into strips through rubbing, and breaks tea cells to squeeze out tea juice through twisting, which is beneficial to the adhesion of tea juice on the surface of tea strips to increase the stickiness, so as to facilitate the rolling of tea leaves into a strip-shaped structure. From manual work to the current automatic equipment, the rubbing and twisting process has become more and more mature. The tea leaves are placed in a rubbing barrel, and a driving motor is used to rotate three cranks to drive the rubbing barrel to rotate on a rubbing disc to repeatedly rub and twist the tea leaves. The existing rubbing and twisting machine mainly relies on a horizontal rubbing disc for rubbing and twisting. When the discharge port on the horizontal rubbing disc is opened, the tea leaves in the rubbing barrel will fall out of the discharge port when the rubbing barrel rotates to the discharge port, which will cause the problem of insufficient rubbing and twisting of tea leaves. Therefore, a rubbing and twisting machine with multiple rubbing and twisting processes is needed to rub and twist tea leaves multiple times to reduce the problem of insufficient rubbing and twisting of tea leaves. SUMMARY

[0009] This application proposes a multi-stage kneading machine. A hopper-shaped discharge bin is installed on the underside of a flat kneading disc, and a conical kneading disc is placed inside the hopper. A crank rotates to drive a transmission assembly, which in turn rotates a ring-shaped component within the hopper. This causes a pressure roller, tilted and rotating on the ring, to knead and squeeze the conical kneading disc, achieving secondary kneading of the tea leaves and improving kneading efficiency. Simultaneously, a lifting and telescopic mechanism is used to open the discharge port on the flat kneading disc. The cover plate can then descend horizontally and retract to detach from the discharge port, allowing the tea leaves to be fed into the conical kneading disc within the hopper for kneading.

Detailed Implementation

[0022] To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0023] Example 1:

[0024] like Figures 1 to 10 As shown, this invention provides a multi-stage kneading machine, comprising a frame 1, a flat kneading disc 2, a kneading drum 3, a tripod 4, a crank 5, a conical kneading disc 6, and a pressure roller 23 mechanism. The flat kneading disc 2 is mounted on the frame 1, the tripod 4 is rotatably mounted on the frame 1 via the crank 5, the kneading drum 3 is fixed to the center of the tripod 4, a bucket-shaped discharge bin 7 is provided on the lower surface of the flat kneading disc 2, the conical kneading disc 6 is disposed within the bucket-shaped discharge bin 7, and the pressure roller 23 mechanism is rotatably disposed within the bucket-shaped discharge bin 7. Any crank 5 is connected to the pressure roller 23 mechanism via a transmission assembly to drive the pressure roller 23 mechanism to rotate on the conical kneading disc 6, thereby performing secondary kneading on the tea leaves on the conical kneading disc 6. Multiple arc-shaped kneading strips 9 are evenly distributed axially on the flat kneading disc 2 and the conical kneading disc 6 for kneading the tea leaves. The bottom of the bucket-shaped discharge bin 7 is equipped with a discharge port, and a discharge trough is inclined on the discharge port to discharge the kneaded tea leaves out of the kneading machine through the discharge trough.

[0025] Specifically, the pressure roller 23 mechanism includes an annular component 21, an annular gear 22, and pressure roller 23. The annular component 21 is rotatably disposed in the bucket-shaped discharge bin 7. There are multiple pressure rollers 23, which are tilted and rotatably disposed on the annular component 21. The annular gear 22 is fixedly connected to the upper end face of the annular component 21. The annular gear 22 meshes with the transmission assembly for transmission. The transmission assembly includes a drive gear 31, a transmission gear 32, a drive pulley 33, and a driven pulley 34. The drive pulley 33 is coaxially connected to the rotating part of any crank 5. The drive gear 31 is rotatably mounted on the frame 1 via a rotating shaft. The driven pulley 34 is connected to the other end of the rotating shaft. The drive pulley 33 is connected to the driven pulley 34 via a belt. The bucket-shaped discharge bin 7 has an arc-shaped opening. The transmission gear 32 is rotatably mounted on the bucket-shaped discharge bin 7. The transmission gear 32 passes through the arc-shaped opening and meshes with the ring gear 22. The drive gear 31 meshes with the transmission gear 32 so that the rotation of the crank 5 drives the drive pulley 33 to rotate, thereby driving the driven pulley 34 to rotate. The rotating shaft causes the drive gear 31 to rotate, thereby driving the transmission gear 32 to rotate, which in turn causes the ring gear 22 meshing with the transmission gear 32 to rotate, thereby driving the ring member 21 to rotate.

[0026] Example 2:

The annular guide 41 has an arc-shaped rack 49, and the end of the screw 45 has a rotating tooth 48. The screw 45 descends to allow the rotating tooth 48 to mesh with the arc-shaped rack 49. It also includes a lever 55. The bucket-shaped discharge bin 7 is provided with an arc-shaped through hole. The lever 55 passes through the arc-shaped through hole and is fixedly connected to the outer ring of the annular guide 41. By rotating the lever 55, the annular guide 41 is driven to rotate, thereby driving the guide roller 42 to drive the guide rod 43 to descend. After the guide roller 42 descends into the horizontal arc-shaped groove 47, the arc-shaped rack 49 on the annular guide 41 meshes with the rotating teeth 48 at the end of the screw 45. As the annular guide 41 continues to rotate, the screw 45 rotates so that the slider 52 at the end of the sleeve 44, which is threaded to it, drives the sleeve 44 to slide on the guide rod 43 to retract, so as to retract the descended cover plate 8 and disengage it from the discharge port 10.

The end of the sleeve 44 is individually connected to the first cover plate 81 and the second cover plate 82 through round blocks. The plug rod is set on one of the round blocks, and the other round block is provided with a plug hole. The plug rod is plugged into the plug hole so as to close the first cover plate 81 and the second cover plate 82 by setting the plug rod, thereby improving the bearing capacity of the circular cover plate 8 formed by the closure of the first cover plate 81 and the second cover plate 82. It also includes a movable limiting block 51. The bottom of the first kneading disc and the second kneading disc are provided with strip-shaped limiting grooves parallel to the axial direction of the guide rod 43. The movable limiting block 51 is slidably located in the strip-shaped limiting groove. The end of the sleeve 44 is provided with a slider 52, which is threadedly connected to the screw 45. The slider 52 is provided with a lug. The movable limiting block 51 is slidably connected to the lug through a limiting rod 53. A spring 54 is sleeved on the limiting rod 53. The two ends of the spring 54 are respectively connected to the lug and the movable limiting block 51, so as to support the first cover plate 81 and the second cover plate 82 by setting the movable limiting block 51, so that the first cover plate 81 and the second cover plate 82 can descend and retract under the rotation of the annular guide member 41 to open the feed port 10. Furthermore, a movable limiting block 51 can also be fixedly provided on the guide rod 43, and a limiting rod 53 is vertically provided on the bottom surface of the flat kneading plate 2 to slide and connect with the limiting tube on the movable limiting block 51, and is elastically connected by a spring 54 to achieve vertical support for the guide rod 43.
