Transmission mechanism of double-layer vibrating screen classifier for tobacco shred production line

Abstract

The transmission mechanism comprises an eccentric transmission main shaft, a mounted bearing, a lower-layer screen eccentric connecting rod shell, a lower-layer screen torque transmission piece, a lower-layer screen torque steering assembly, an upper-layer screen torque steering assembly, an upper-layer screen torque transmission piece and an upper-layer screen eccentric connecting rod shell. According to the technical scheme, the movement directions of the torque transmission pieces of the upper-layer screen and the lower-layer screen, the appearance structure of the torque steering assembly and the shaft diameter of a main shaft of the eccentric transmission assembly are improved, it is guaranteed that in the operation process of the double-layer vibration screen, abrasion of an eccentric shaft and breakage of a transmission pull piece are avoided, and meanwhile the operation noise of the whole machine is reduced to the minimum; equipment failure shutdown caused by damage and breakage of the transmission pull piece and abrasion of the eccentric main shaft is greatly reduced, the operation stability of the equipment is improved, and the repair and maintenance cost of the equipment is reduced to the minimum.

Description

technical field [0001] The invention belongs to the technical field of double-layer vibrating screening machines, and in particular relates to a transmission mechanism of a double-layer vibrating screening machine for silk production lines. Background technique [0002] The double-layer vibrating screen (hereinafter referred to as the double-layer vibrating screen) uses the eccentric drive assembly and the torque steering assembly to generate periodic reciprocating vibration of the upper and lower troughs, so that the material moves in the trough, and realizes continuous and large-flow transportation of materials. At the same time, the screens at the bottom of the upper and lower grooves can be independently designed according to the process requirements and material characteristics, to screen the different specifications of fragments, soot and tobacco powder in the shredded tobacco to improve the purity of the material. [0003] like figure 1 Shown is the schematic diagram...
