Background
The tobacco stem bale opener is a first procedure of tobacco stem processing, and the main task of the procedure is that after a gunny bag filled with tobacco stems is cut by an automatic opening mechanism, the tobacco stems are poured out by a mechanical arm, then the empty gunny bag is put into a recovery belt to enter a collection box, and the tobacco stems enter the next procedure to be processed. The automatic opening mechanism of the device adopts a transverse in-line type cutting mode for cutting the stem bag: when the stem bag moves to the cutting piece along with the belt conveyor, the stop mechanism is put down, and the cutting piece carries out transverse cutting. The defects are that: 1. the opening is small, and the stem is easy to be hidden in the empty bag. The mechanical arm still can not thoroughly topple over after 3 times of swinging, and each empty included stem is about 0.3-0.5KG, so that operators need to check the empty included stems; 2. the phenomenon of packet drop is serious. The cutting mode requires that the cut stem bag is regular in size, full, the sewing opening faces the non-cutting surface, the cut stem bag can be cut smoothly, the stem bag coming from the actual production is often irregular, large and small, full and concave, the sewing opening is always inconsistent in placement direction, the cut is easy to be generated, the cut is not thorough and even the cut cannot be performed, the mechanical arm cannot pour out the tobacco stem when the stem bag is toppled after being cut, the stem bag and the tobacco stem cannot be separated, and the mechanical arm falls off due to overweight of the tobacco bag when the mechanical arm is thrown.
The problems above cause that the equipment work efficiency is low, the emergency exit can not normally be closed (need frequently get into inside the equipment, the manual work will fall the stalk package and cut off the tobacco stalk), tobacco stalk and dust overflow from the emergency exit, on-the-spot environment is poor, need special personnel to inspect empty stalk package, the human cost increases.
