Description

Tobacco leaf papermaking device

Technical Field

The utility model relates to a tobacco leaf field of regenerating, concretely relates to tobacco leaf papermaking device.

Background

In the cigarette manufacturing process, leftover materials such as tobacco stems, fragments, tobacco powder and the like are often left, the materials cannot be directly used as raw materials for making cigarettes, but the fragments and the tobacco powder are the same as cut tobacco before being crushed, so that the fragments and the tobacco powder are unfortunately thrown away. To utilize these materials, there are currently three reconstituted tobacco technologies: rolling, thick stock, paper making.

And (3) rolling: pressing tobacco stems and tobacco powder into tobacco leaves with certain pressure "

Thick slurry method: sticking tobacco stems and tobacco powder into tobacco leaves by using safe adhesive

A papermaking method: the most advanced process is to extract the effective components of tobacco stems and tobacco powder, remove the bad components, make the remaining red fiber into paper, and add the effective components back.

Compared with the sheet prepared by a rolling method and a thick pulp method, the reconstituted tobacco prepared by the paper-making method has the advantages of good filling performance, low tar release amount and the like. The paper-making reconstituted tobacco is derived from tobacco, is different from natural tobacco, and is an indispensable important raw material component of a cigarette formula. In recent years, the paper-making reconstituted tobacco technology has been developed greatly and plays an increasingly important role.

The production of the paper-making method reconstituted tobacco takes tobacco fragments, tobacco wood and roots as main raw materials, comprehensively applies the leaching process in the chemical and pharmaceutical technology and the key processes of pulping, papermaking and the like in the paper-making technology, and adopts mechanical and physical methods to process the reconstituted tobacco with similar physical parameters, water content and the like of redried leaves.

Generally, the papermaking process can be divided into the main steps of pulping, modulation, papermaking and the like, and specifically comprises the following steps: firstly, soaking tobacco stems in water, and then extracting: pulping the extracted solid matter into tobacco stalk pulp by two steps of coarse pulping and fine pulping: and then mixing the tobacco stems and the tobacco powder, adding wood pulp to prepare mixed slurry, and feeding the mixed slurry into a paper machine to make the tobacco leaf paper.

The inventor finds that at least the following problems exist in the prior art: at present, after the edge of the water needle at the net part of the paper machine is cut, the water needle is blown to a water receiving disc under a net part forming net through a high-pressure water spraying pipe and flows to a sand settling disc and then to the upper end of a white water barrel. Because the mobility of the trimming slurry is poor, the trimming slurry flows to a sand setting plate after a certain amount of water is accumulated on a water receiving plate, so that quantitative fluctuation is easy to cause, and the quality of the slice is influenced; the edge-cutting slurry finally flows to the upper end of the white water barrel, and the upper end of the white water barrel is provided with an overflow port, so that most of the slurry is discharged through the overflow port, and the slurry is wasted.

The nozzles 2 are arranged at the edge of the forming wire 1 and are used for ejecting fluid for cutting the pulp on the forming wire 1. The pulp recovery device 3 comprises a casing 31, the casing 31 is provided with an inflow 32 communicating with the cavity 30 of the casing 31, and the inflow 32 is provided at the edge of the forming wire 1. Wherein the nozzle 2 is configured such that the injected fluid can enter the cavity 30 via the inflow opening 32 of the slurry recovery device 3.

The slurry recovery device 3 has, for example, a rectangular box structure, and an inflow port 32 is provided in the top surface of the box. The slurry recovery device 3 may also adopt other structural forms, and other implementation modes will be given later.

The nozzle 2 is used to eject fluid under pressure to effect cutting of the pulp edge.

With reference to fig. 1, the section of the edge of the forming wire 1 that needs to be cut by the water jet ejected by the nozzles 2 is located above the inflow opening 32. This section, although located above the inflow opening 32, does not fall into the inflow opening 32 due to the support of the rest of the forming wire 1. The nozzle 2 then sprays water towards the section to cut the irregular part of the pulp edge on the forming wire 1, i.e. the irregular part of the pulp edge is cut by the water needle, so that the edge of the pulp on the forming wire 1 becomes regular and tidy. Because the lower part of the section is the inflow port 32 and the cavity 30 communicated with the inflow port 32, the leftover materials cut by the water flow fall into the cavity 30 under the action of gravity and the jet force of the water flow, so that the automatic and synchronous collection of the leftover materials in the cutting process is realized.
