Technical Field

The invention relates to the technical field of cigarette processing in the tobacco industry, in particular to a tobacco stem directional arrangement feeding device suitable for a cut stem machine.

Background

The cut stem machine is an important device in the tobacco shred manufacturing line, and has the functions of changing the original physical form of the tobacco stems and increasing the surface area of the tobacco stems by shredding the tobacco stems, so that the subsequent processing requirements (such as feed liquid absorption, puffing drying and the like) are met. The two factors influencing the quality of the cut stems mainly include: a cut stem machine and the state of the supplied tobacco stems. For the cut stem machine, the diagnosis of an equipment manufacturer engineer and the manual debugging of electricians and mechanic repairers are commonly adopted in the industry; for the supplied tobacco stems, the quality of the raw materials of the tobacco stems is ensured from the source, and the research on the tobacco stem state in the feeding process at the front section of the stem shredding machine is still in a blank stage, so that the improvement on the tobacco stem state and the shredding quality through the feeding device of the stem shredding machine is very important.

The feeding device of the cut stem machine aims to convey the tobacco stems processed by the pre-stem pressing procedure to the inlet of the cut stem machine quantitatively, uniformly and continuously so as to ensure that the cut stem machine can cut stems continuously and uniformly. The existing commonly used stalk cutting and feeding device comprises a horizontal vibration feeding device and a vertical feeding device. Compared with the advantages and the disadvantages of the two, a horizontal vibration feeding mode is generally adopted in the industry to feed the cut stem machine. The horizontal feeding type vibrating conveyor is similar to a movable vibrating groove trolley, and the working principle of feeding the cut stem machine is as follows: the groove-vibrating trolley resonates in a certain direction under the driving of the transmission device, and according to the Newton's third law, the inertia force of the groove body and the inertia force of the tobacco stems in the groove body are balanced with each other, so that the tobacco stems and the groove body resonate in opposite directions and same in amplitude. When the vibration acceleration of the feeding vibration groove reaches a certain value, the materials are thrown in the groove body along the conveying direction, the materials move forwards until the materials fall down to be contacted with the groove body again, the acceleration is obtained again, the materials are thrown up again and move forwards, and the steps are repeated, so that the purpose of conveying the materials is achieved. The amplitude and frequency of the feeding trolley can be adjusted according to different tobacco stem incoming materials and the cut stem conditions of the cut stem machine so as to achieve the optimal conveying and cutting states.

However, the horizontal vibration feeding mode for feeding the stem cutting machine in the actual production process has corresponding problems: the horizontal feeding type vibrating conveyor can control the flow of supplied materials to be matched with the production capacity of the stem cutting machine, but cannot control the cutting direction of the materials and the cutter rod. Because the tobacco stems are in an elliptical strip shape and the positions of the tobacco stems and the cutting edges are irregularly distributed, the difference between the cut stem shape and the long and thin shape of the tobacco shreds is large, the tobacco shreds which do not meet the standard width are low in filling capacity after being puffed and dried in subsequent procedures, and the utilization rate of the stem shreds is obviously reduced.
