[0034] In the embodiment, the linear driving mechanism comprises a rack 22 arranged on the rack 1 and extending to the support frame 2 to form a continuous transmission path; the two sides of the stable frame 10 are slidingly assembled on the rack 1 through guide wheels; and a third motor 23 is arranged on the stable frame 10, and a gear in mesh with the rack 22 is arranged on the output shaft of the third motor 23.
[0035] The working principle of the embodiment is as follows:
[0036] The tobacco frame 5 to be emptied is placed on the roller conveying mechanism by external conveying equipment (or manual assistance), and the roller conveying mechanism is started to drive the tobacco frame 5 to move to the preset clamping position of the rack 1. When the tobacco frame 5 moves to the preset clamping position, the second telescopic cylinder is started, the piston rod is extended, the positioning plate is lifted from the roller gap to above the conveying surface, the tobacco frame 5 is intercepted and accurately positioned, and the tobacco frame 5 is prevented from continuing to move or deviating.
[0037] After positioning, the first telescopic cylinder 9 is started, the piston rod is extended, the roller conveying mechanism and the positioned tobacco frame 5 are moved upward, the tobacco frame 5 is accurately guided into the opening in the middle of the stable frame 10 under the guidance of the guide plate 17 at the bottom end of the stable frame 10, and the tobacco frame 5 reaches the preset clamping height of the clamping assembly 4 until the first telescopic cylinder 9 stops working and the tobacco frame 5 remains in the jacked-up state.
[0038] After the tobacco frame 5 is jacked up to the position, the third telescopic cylinders 12 on the two sides are simultaneously started, the piston rods are retracted, the swing rods 16 are swung, the swing rods 16 drive the transmission rods 13 to rotate around the supports 14, and then the L-shaped clamping blocks 15 on the transmission rods 13 are synchronously moved close to the tobacco frame 5 until the clamping blocks 15 are firmly attached to the two sides of the tobacco frame 5, the tobacco frame 5 is fixed in the stable frame 10, and the third telescopic cylinders 12 remain in the extended state to ensure firm clamping.
[0039] After clamping, the first motor 20 is started to drive one of the connecting rods 19 to rotate, the two connecting rods 19 are synchronously reversely rotated through the transmission mechanism, and then the two cover plates 18 are closed to cover the opening at the top end of the tobacco frame 5 to prevent material from spilling during the subsequent turnover process.
[0040] After the material is blocked, the third motor 23 is started to drive the gear on the output shaft to rotate, the gear is in mesh with the rack 22, the stable frame 10, the frame 3 and the fixed tobacco frame 5 are driven to slide along the guide wheels, and the tobacco frame 5 is moved from the rack 1 to the support frame 2 (emptying station). After reaching the preset position, the third motor 23 stops working, and the frame 3 is fixed.
[0041] After the frame 3 is fixed, the second motor 21 is started to drive the rotation shaft of the stabilizing frame 10 to rotate, thereby driving the stabilizing frame 10, the clamping assembly 4 and the tobacco frame 5 to synchronously overturn until the tobacco frame 5 overturns by 180° (the opening faces downward), the second motor 21 stops, and the tobacco frame 5 remains in the overturned state, at this time, the material in the tobacco frame 5 is ready to be poured out under the action of gravity.

[0043] After the material pouring is completed, the second motor 21 is reversed to drive the stabilizing frame 10, the clamping assembly 4 and the empty tobacco frame 5 to synchronously overturn and reset to the initial vertical state, then the first motor 20 is forward rotated to drive the cover plate 18 to close (to prevent foreign matters from entering when the empty tobacco frame 5 moves), and the third motor 23 is reversed to drive the frame 3, the stabilizing frame 10 and the empty tobacco frame 5 to move from the supporting frame 2 back to the initial position of the rack 1.
[0044] After the frame 3 is reset, the third telescopic cylinder 12 is contracted to drive the transmission rod 13 to rotate, the clamping block 15 is away from the empty tobacco frame 5, and the clamping on the empty tobacco frame 5 is released, then the first telescopic cylinder 9 is contracted to drive the roller conveying mechanism and the empty tobacco frame 5 to move downward and reset to the initial conveying height, the second telescopic cylinder is contracted, and the positioning plate is lowered to below the roller, finally, the roller conveying mechanism is started to drive the empty tobacco frame 5 to convey outward, the empty tobacco frame 5 is discharged, the whole material pouring process is completed, and the mechanism waits for the next tobacco frame 5 to be fed and enters the next cycle.
