Description

Technical Field

[0001] The invention relates to the technical field of tea processing equipment, in particular to a tea cutting machine for rolling tea production. Background Art

[0002] Existing tea generally includes leaves and buds of tea trees, and its main ingredients include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid. Long-term and reasonable drinking is beneficial to the human body. Therefore, tea beverages made from tea are one of the three major beverages in the world.

[0003] With the continuous development of tea-related technologies, the drinking and processing methods of tea have also begun to diversify. For example, matcha, which is directly consumed, is the raw material for tea produced by grinding fresh tea leaves after cutting, withering, and drying. However, during the actual production process, the applicant discovered that the cutting mechanism of the currently used tea cutting machines mostly cuts in a single direction. Although it can meet the production purpose of preliminary processing of tea, when large quantities of tea are cut, some tea leaves that are bent and contracted due to pressure can easily pass through the cutting mechanism intact, which reduces the quality of the cutting process and directly flows out without re-cutting, which also has an adverse effect on the processing quality of other subsequent processes. However, the re-cutting process will increase the use cost of the tea cutting machine and reduce its use efficiency, thereby causing problems in the use cycle of the overall equipment, which is difficult to solve.

[0028] Embodiment 4 See also Fig.11 , Fig.14, a plurality of first main air guide grooves 27 are provided with pneumatic linkage components 30, the pneumatic linkage components 30 include a T-shaped rod 301, and the outer sides of the two ends of the T-shaped rod 301 are respectively sleeved with a constraint ring 302 and a guide ring 303, the constraint ring 302 and the guide ring 303 are both fixedly sleeved inside the pneumatic linkage component 30, and the guide ring 303 is provided with a plurality of air outlet holes in communication with the space of the pneumatic linkage component 30, one end of the T-shaped rod 301 is sleeved with a return spring 305, and the two ends of the return spring 305 are respectively connected to the surface of the constraint ring 302 and the surface of one end of the T-shaped rod 301; The other end of the T-bar 301 is fixedly connected to a conical tube head 304 which is clamped with one end port of the first main air-flowing groove 27, and the surface of the conical tube head 304 is coplanar with the surface of the first rubber knife roller 7. The middle surface of the T-bar 301 is sheathed with a conical adjustment cylinder 307 and an adjustment ring 306, and the surface of the conical adjustment cylinder 307 is clamped inside the adjustment ring 306, and the inner side of the middle part of the conical adjustment cylinder 307 is fixedly sleeved on the middle surface of the T-bar 301, and the surface of the adjustment ring 306 is fixed to the inner wall of the middle part of the corresponding first main air-flowing groove 27. As the T-bar 301 is pressed and displaced, the connection gap between the adjustment ring 306 and the conical adjustment cylinder 307 increases, so that the first main air-flowing groove 27 is in an open state.

[0029] Specific use of this embodiment: Considering the need to know the sharpness of the cutter in the device in real time during the reciprocating use, the pneumatic linkage assembly 30 is set to detect the transverse blade inside the first tea cutting roller 5 in real time without interfering with the air supply of the first main air groove 27. The specific principle is as follows: During the interval of equipment use, the first servo motor 9 outputs and links the first chain transmission mechanism and the second chain transmission mechanism to align the transverse blade inside the first tea cutting roller 5 with the conical tube head 304. Then, the first servo motor 9 is activated to output, and the passive air supply component 25 synchronously links the first servo motor 9 and conveys the pressurized air to the first main air guide groove 27 through the branch air guide valve pipe 262 in the Y-shaped air guide pipe 26 that is set with the first rubber knife roller 7 and is in an open state, and the corresponding semi-open air guide groove. The air entering the first main air guide groove 27 will press the T-bar 301 and cause the T-bar 301 to move. At this time, if the wear of the transverse blade is small and it is still in a usable state, the tip of the transverse blade will contact the conical tube head 304 or be in a small gap state that is not enough to make the conical tube head 304 give way to the opening port of the first main air-intake groove 27. In this way, the air will not be able to be discharged through the first main air-intake groove 27, and because of the one-way flow state of the inlet check valve tube 256, the air inside the elastic airbag 255 will be in a state of only entering but not leaving. Therefore, the air pressure sensor 259 will detect that the pressure inside the elastic airbag 255 is gradually increasing and cannot be balanced at a certain value. If the transverse blade is worn out and cannot be used, the tip of the transverse blade will be in a large gap with the conical tube head 304, which is large enough to make way for the open port of the conical tube head 304 to the first main air flow groove 27. Subsequent air will not be able to be discharged smoothly through the first main air flow groove 27, and the air pressure sensor 259 can also detect that the pressure inside the elastic airbag 255 reaches a certain value and remains in balance for a long time without changing.
