Description
Technical Field
The invention relates to the field of tobacco stem processing equipment, in particular to a secondary sorting device for tobacco stem shreds.
Background
The stem silk separation system of the existing ZJ17 cigarette making machine set is a secondary sorting device through primary and secondary air separation, and the production process mainly adjusts the removed stem quantity (primary sorting) by adjusting the height of a guide plate.
When the height adjustment of the guide plate is low, more tobacco shreds in the stem shred mixture entering the secondary air separation device are influenced by the structure of the original secondary air separation device, so that the tobacco shred content in the rejected stems is high, and great waste is caused.
When the height of the guide plate is adjusted to be higher, although the cut tobacco in the cut stem mixture entering the secondary air separation device is less, the cut stems separated are less, so that the cigarettes containing more stems are easy to cause the piercing and the folding of the cigarettes (particularly, the cigarettes are easy to be pierced by the tobacco stems when manufacturers vigorously develop thin cigarettes at present), the weight deviation of the cigarettes is increased, and the suction resistance is increased. Meanwhile, the tobacco rod contains more stems, so that the equipment is easily blocked and strips are easily run, and the efficiency and consumption of the equipment are influenced.
The secondary sorting is to sort the tobacco shreds again in the stems sorted out once, and the purpose is to solve the phenomenon that the tobacco shreds are wasted due to the primary sorting, but the original secondary sorting principle is a simple negative pressure principle, cannot be fully separated, still has the tobacco shreds to be wasted, and meanwhile, the sorting flow is small, so that the primary sorting quantity is required to be not large, partial stems cannot be separated, and the quality problem of cigarettes is caused. (particularly, the existing fine cigarette is sensitive to the stem of the cigarette and is easy to puncture, so that the primary stem separation amount needs to be increased to the greatest extent for secondary stem separation, and the secondary stem separation capability of the existing sorting device is limited).
The problems in the stem and cut stem separation of the existing ZJ17 cigarette making and tipping machine set are as follows:
1. the secondary separation of the original machine is simple negative pressure absorption and is easily influenced by a wind power system of the machine
2. The separation effect is not good, and a great amount of cut tobacco contained in the separated stem can not be directly utilized, thereby causing great waste of cut tobacco
3. The secondary separation device of the original machine has low separation capability, so that the stem content of cigarettes is high, and the cigarettes are punctured and the suction resistance is increased (particularly medium and thin cigarettes).
Disclosure of Invention
The invention provides a secondary sorting device for tobacco stems, which aims to solve the problems in the prior art, increase the amount of tobacco stems subjected to stem removal, reduce the omission of stem removal, avoid waste and improve the dispersion of the tobacco stems so that the tobacco stems are distributed more uniformly.
The tobacco stem separating device comprises a stem shred separating channel connected with a stem shred channel outlet, wherein a tobacco stem outlet is formed in the bottom of the stem shred separating channel, and a tobacco shred channel is formed in the top of the stem shred separating channel; the cut tobacco channel is connected to the flow distribution cover through the cut tobacco return channel, a negative pressure generator is mounted on the cut tobacco return channel, and cut tobacco is sucked out of the cut stem separation channel through the negative pressure generator and flows into the cut tobacco return channel; the shunting cover is connected with a dust removal channel and a tobacco shred outlet, and the tobacco shreds fall into the tobacco shred outlet through inertia under the gas-object separation effect generated by the shunting cover.
Further improved, the inner wall of the cut stem separation channel is in a Z-shaped fluidized bed shape.
In a further improvement, the negative pressure generator is connected with a starting control box.
In further improvement, the dust removal channel is connected with an air outlet.
The invention has the beneficial effects that:
1. the cut stem content of the cigarette is less than or equal to 0.20 percent, the cut tobacco content of rejected material stems of the cigarette making machine is less than or equal to 10 percent, the cut tobacco recycling rate is 100 percent, and the waste is reduced.
2. The additional negative pressure device additionally opens a channel to send back the cut tobacco, thereby avoiding cut tobacco blockage caused by the bottleneck of cut tobacco suction quantity at the cut tobacco outlet at the upper end of the original device.
3. The Z-shaped fluidized bed shape of the cut stem separation channel improves the separation action distance, enhances the cut stem separation capacity, and changes the situation that the secondary cut stem separation capacity is insufficient after the stem output quantity is improved.
4. And the maintenance is free.
