Description

Tobacco stem carding device before the stem cutter

technical field

The utility model relates to a tobacco stem carding device before a stem cutting machine.

Background technique

Shredded tobacco stems are used as one of the cigarette formulas, which can not only reduce tar and harm, but also expand the added value of tobacco crops. Appropriate cutting process of cut stems can make the shape of cut stems closer to the shape of shredded tobacco, and can improve the compatibility of cut stems and cut leaves, thereby improving the effective utilization rate and blending uniformity of cut stems. Based on various industry research results and actual production experience, suitable shredded stems can not only improve the stability of physical quality, chemical indicators and sensory quality of finished cigarettes, but also expand the scope of use of cut stems in cigarette brand names.

Referring to Fig. 1, the tobacco stem conveying link before the existing German TOBSPIN type stem cutting machine is mainly composed of tobacco stem blanking port 1, vibration trolley 2, stem cutting machine copper row chain 3 and rotating cutter 4 and other parts. The production process of the stem cutting machine is as follows: the pressed tobacco stems are transported to the stem blanking port 1 through the belt according to a certain flow rate, and enter the vibrating groove with a certain slope in the vibrating trolley 2 through the tobacco stem blanking port 1 21. Convey through the vibration groove 21 to a wedge-shaped space composed of upper and lower conveying copper chains. During the process of the copper chains rotating and transporting the tobacco stems forward, the tobacco stems are compacted and sent to the rotation of the stem cutting machine. At the cutter roll, the rotating blade 4 on the cutter roll cuts the compacted tobacco stems into shredded stems with a set thickness and conveys them to the next process. Therefore, the arrangement of the tobacco stems before compaction directly determines the shape of the shredded stems. In order to improve the arrangement of the tobacco stems before compaction, many tobacco factories have made some explorations, but they cannot effectively apply the actual production and processing of the enterprise. . There is no tobacco stem carding device or mechanism during the entire conveying process of the material, and the tobacco stems are arranged randomly and disorderly, and the directional cutting of the tobacco stems cannot be realized. Although the device disclosed in the existing relevant patents can realize the straightening function of tobacco stems to a certain extent, it is easy to cause material blockage, and the flexibility to match production and processing is not strong. The size and installation space requirements of the stem trimming device are relatively high.
