Embodiment 1

[0047] like Figure 1 to Figure 6 As shown, a kind of tobacco stem screening equipment described in this embodiment includes a driving roller 7, and the driving roller 7 drives the belt bundle 4 to move, and the tobacco stems to be screened are put on the belt bundle 4, and the driving roller 7 drives the belt bundle 4 movement, the tobacco stems put on the belt bundle 4 follow the movement of the belt bundle 4, a gap is formed between a plurality of belts arranged at intervals, if the volume of the tobacco stem is smaller than the gap, it will leak through the gap, and if the volume of the tobacco stem is not smaller than the gap, Stay on belt harness 4. Since the belt bundle 4 is composed of a plurality of belts spaced apart from each other, a gap is formed between the plurality of belts spaced apart from each other, and the gap is strip-shaped, and its width is the distance between two adjacent belts. The tobacco stem screening equipment is mainly used for screening the no...

Embodiment 2

[0052] like Figure 1 to Figure 6 As shown in the tobacco stem screening equipment described in this embodiment, the radial cross-section of the belt is diamond-shaped, and the driving roller 7 is provided with a groove matching the belt. The diamond-shaped belt bundle 4 in circular motion screens the tobacco stems by utilizing the gaps formed between multiple belts, and the stem crutch moves along with the belt bundle 4 until the stem crutches slide out of the hopper, which ensures the continuous operation of the tobacco stem screening. The radial cross-section of the belt is diamond-shaped, which is convenient for screening the tobacco stems, ensures the effective separation of the tobacco stems, prevents clogging, and improves the separation efficiency of the tobacco stems.

[0053] Furthermore, the tobacco stem screening equipment also includes: a first discharge device 6, arranged directly below the belt bundle 4, to collect the tobacco stems leaking through the gap, and ...

Embodiment 3

[0055] like Figure 1 to Figure 6 As shown, the tobacco stem screening equipment described in this embodiment includes a screening device and a vibrating device, the screening device is used to screen tobacco stems, and the vibrating device drives the screening device to vibrate up and down.

[0056] Specifically, the screening device is a belt conveyor, and the belt conveyor includes a belt bundle 4 composed of a plurality of belts arranged at intervals. The vibrating device is arranged below the belt bundle 4, and the vibrating device drives the belt bundle 4 moving in a plane to vibrate up and down. Since the belt conveyor circulates on the same plane, the tobacco stem placed on the belt bundle 4 moves with the belt bundle 4. When the stem turns in the tobacco stem are stuck in the gap formed between multiple belts, the above qualified The tobacco stems just cannot pass through the gap, and fall to the first discharge device 6 that is arranged on the belt bundle 4 directly...

Abstract

The invention discloses a device for screening tobacco stems, which comprises: a screening device for screening tobacco stems; a vibrating device for driving the screening device to vibrate up and down. The vibrating device of the invention drives the belt bundle to vibrate regularly up and down to ensure effective screening and separation of the tobacco stems, prevent blockage, and improve the separation efficiency of the tobacco stems.

Description

technical field [0001] The invention belongs to the technical field of tobacco industry screening, and in particular relates to tobacco stem screening equipment. Background technique [0002] In the prior art, in the cut stem production line of a cigarette factory, there are many stems in the original stem during the cut stem production process, which often leads to the plugging of the stem press machine, which seriously affects the cutting quality of the cut stem. At the same time, with the rapid development of slim cigarettes, cigarette factories have higher requirements on the cutting quality of cut stems. The existing stalk screening equipment, due to the irregular shape of the stalks, often leads to blockage of the sieve plate, and it is not easy to clean and dredge after the sieve plate is blocked, which directly affects the screening effect of the stalks and the shredded stems behind quality. How to efficiently remove the stalks is a technical problem that cigarette...
