[0038] The utility model is further described below in combination with the drawings and specific embodiments.

[0039] The primary tobacco leaf layering and grading identification equipment comprises a machine body 1, a multi-station tobacco leaf storage box B arranged on the machine body 1, and a primary tobacco leaf layering and taking device A1 arranged above the tobacco leaf storage box. The primary tobacco leaf layering and taking device A1 comprises a suction disc mechanism A2 for sucking and placing primary tobacco leaves in the tobacco leaf storage box, a first lifting mechanism A3 for controlling the lifting of the suction disc mechanism, and a leaf protection mechanism A4 arranged on the machine body and beside the suction disc mechanism.

[0040] The machine body 1 comprises an upper part 101 and a lower part 102. The upper part 101 and the lower part 102 are respectively welded into a cuboid-shaped frame through a plurality of pipes. An outer shell or a sliding door is installed on the cuboid-shaped frame to reduce the invasion of external pollutants. The upper part 101 is stacked on the lower part 102, and a positioning pin and a positioning hole are arranged at the contact position of the two parts. The positioning pin and the positioning hole are inserted and matched to achieve the stacking and installation of the upper part 101 and the lower part 102. The machine body 1 is composed of the upper part 101 and the lower part 102, so that it is convenient to transport independently during transportation.

[0041] The first lifting mechanism A3 can be a lifting cylinder, an electric cylinder, etc. The first lifting mechanism A3 of the present application specifically comprises a first outer shell A26 (the first outer shell A26 covers the entire periphery of the first lifting mechanism, and most of the components of the first outer shell are omitted in the drawing for easy display), a servo motor A27 fixed to the upper part of the first outer shell, and a synchronous belt mechanism A28 arranged on the output end of the servo motor. An upper plate A29 is fixedly connected to the belt of the synchronous belt mechanism. Two pulleys of the synchronous belt mechanism are arranged on the upper part and the lower part of the first outer shell, respectively (when the servo motor works, the belt of the synchronous belt mechanism is driven to circulate, thereby driving the upper plate A29 to lift in the first outer shell). First guide rods A30 are fixedly connected to the two sides of the upper plate A29. The lower ends of the first guide rods A30 pass through the lower part of the first outer shell and are fixedly connected to a lower plate A31. The lower surface of the lower plate A31 is connected to the upper surface of a suction disc main beam A15 through a plurality of springs A32. The springs A32 can play a buffering role to avoid damaging the tobacco leaves by a large force.

[0042] The suction disc mechanism A2 comprises a suction disc main beam A15 and a plurality of groups of parallel suction disc branches A16 vertically fixed below the suction disc main beam (the suction disc main beam A15 and the suction disc branch A16 can be thin shells made of stainless steel), the lower surface of the suction disc branch A16 is provided with a plurality of strip-shaped suction disc air inlet grooves A17 (1cm thick sponge can be attached on the suction disc air inlet groove to reduce the damage of the suction disc to the tobacco leaves during operation), the suction disc air inlet groove A17 is in communication with the negative pressure cavity in the suction disc branch A16 and the suction disc main beam A15, the suction disc main beam is provided with a suction disc air outlet A25 connected with the negative pressure mechanism A18, and the suction disc air inlet groove A17 of the suction disc branch A16 generates negative pressure under the action of the negative pressure mechanism, so as to adsorb the tobacco leaves.

[0043] Specifically, the negative pressure mechanism A18 comprises a wind pump A19 arranged in the lower part of the machine body, a main air duct A20 connected with the inlet end of the wind pump, and an air outlet A21 connected with the outlet end of the wind pump, the main air duct A20 is provided with a side air pipe A22 connected thereto, the inlet end position of the main air duct A20 is provided with a main air duct butterfly valve A23, the inlet end position of the side air pipe A22 is provided with a side air duct butterfly valve A24, and the inlet end of the main air duct is connected with the suction disc air outlet A25 on the suction disc main beam A15 through a pipeline.

[0044] During operation, the wind pump A19 continuously works, and the opening and closing states of the two butterfly valves (the main air duct butterfly valve A23 and the side air duct butterfly valve A24) are mutually exclusive (that is, opposite), when the main air duct butterfly valve is opened and the side air duct butterfly valve is closed, negative pressure is generated in the main air duct and the suction disc air inlet groove A17, that is, the suction disc generates negative pressure to suck the tobacco leaves; on the contrary, when the main air duct butterfly valve is closed and the side air duct butterfly valve is opened, negative pressure is generated in the side air duct, and there is no negative pressure in the suction disc air inlet groove A17, that is, the suction disc does not generate negative pressure, and the suction disc drops the tobacco leaves, so that the structure can repeatedly generate negative pressure on the suction disc air inlet groove A17 of the suction disc mechanism, and can avoid the problems of easy damage and insufficient negative pressure caused by repeated opening and closing of the wind pump A19.

[0045] The leaf guard mechanism A4 includes a leaf guard mechanism main frame A5 fixed on the machine body, a leaf guard rod rotating shaft A6 rotatingly connected to the leaf guard mechanism main frame and located outside the suction disc mechanism, and a plurality of spaced leaf guard rods A7 vertically fixed on the leaf guard rod rotating shaft. The leaf guard mechanism main frame A5 is provided with a first driving mechanism A8 (which can be a pneumatic cylinder, an electric push cylinder, etc.) capable of driving the leaf guard rod rotating shaft A6 and the leaf guard rod A7 to rotate. The leaf guard rod is in a folding and unfolding position under the action of the first driving mechanism. In the folding position, the leaf guard rod A7 is flush or close to flush with the suction lower surface (i.e. the lower plane where the suction disc air inlet groove A17 is located) of the suction disc mechanism A2 to be able to support the primary cured tobacco leaves adsorbed by the suction disc mechanism. In the unfolding position, the leaf guard rod is perpendicular to the suction lower surface of the suction disc mechanism and does not interfere with the lifting action of the suction mechanism. That is, the leaf guard rod repeatedly swings between the horizontal position and the vertical position. When the suction mechanism is adsorbing tobacco leaves, individual tobacco leaves may fall due to insufficient adsorption area and insufficient adsorption force. When the suction mechanism needs to lift (mainly downward to adsorb tobacco leaves), the leaf guard rod swings to the vertical position to avoid the lifting of the suction mechanism.

[0046] The leaf guard mechanism main frame A5 includes a main beam rod A9 fixedly installed on the machine body and a cantilever rod A10 vertically connected to both ends of the main beam rod. The leaf guard rod rotating shaft A6 has two rods parallel to the main beam rod A9. One of the leaf guard rod rotating shafts A6 is close to the main beam rod A9, and the other is close to the free end of the cantilever rod (i.e. away from the main beam rod A9). Both ends of the leaf guard rod rotating shaft A6 are rotatingly connected to the cantilever rod A10. Two leaf guard rod driving cylinders A11 (the first driving mechanism A8 is the leaf guard rod driving cylinder A11) are fixedly arranged on the inner side of one cantilever rod. The free ends of the rods of the leaf guard rod driving cylinders A11 are connected to the leaf guard rod rotating shaft A6 through a swing arm A12. The two leaf guard rod rotating shafts A6 and the leaf guard rod A7 are relatively swung (i.e. the leaf guard rod A7 rotates around the axis of the leaf guard rod rotating shaft A6) under the action of the leaf guard rod driving cylinder A11 to switch the leaf guard rod A7 between the horizontal position and the vertical position.

[0047] The cantilever rod A10 is fixedly installed with a limiting plate A13 sleeved on the leaf guard rod rotating shaft A6 on the inner side. The limiting plate A13 is provided with two spaced convex pins A14. One end of the swing arm A12 is fixed on the leaf guard rod rotating shaft A6, and the other end is hingedly connected to the free end of the rod of the leaf guard rod driving cylinder A11. The two convex pins A14 are located on both sides of the swing arm to limit the swing angle. The cantilever rod A10 and the leaf guard rod rotating shaft A6 are rotated under the action of the rod of the leaf guard rod driving cylinder A11. The leaf guard rod A7 can be limited to move in the horizontal position and the vertical position through the limiting of the two convex pins A14.

The film sealing drive plate D3 is driven to lift by a third lifting drive mechanism D4 (which can be an electric push cylinder or a gas cylinder) fixed to the vertical plate. A penetrating slot D5 is arranged in the middle of the bottom plate B8 (the penetrating slot is arranged in the bottom of the post-inspection box body B4). An installation frame D6 and a film sealing support D7 rotatably connected to the installation frame are arranged on both sides of the penetrating slot D5. A film sealing reel D8 and a film sealing kit D9 (which is a prior art, including an electric heating wire, bakelite, and high-temperature cloth, etc., to heat and fuse the film) are arranged on the film sealing support D7. A frame transmission shaft D10 is connected to the length direction of the film sealing support D7.
