Roll type strip filamentation system

Abstract

The invention provides a roll-type strip filamentation system. The roll-type strip filamentation system is characterized by comprising a feeding trolley for transferring strip rolls; the unwinding machine is connected with the feeding trolley in a matched mode and controls the strip coil to unwind the strip; the threading mechanism is connected with the unreeling machine in a matched mode and controls threading of the strip; the traction mechanism is connected with the threading mechanism in a matched mode and controls the strip to move; the moisture regaining and/or feeding mechanism is used for regaining moisture and feeding the front and back surfaces of the strip during traction; the fixed-width slitting mechanism is connected with the traction mechanism in a matched mode and controls the strips to be slit into tows in a fixed-width mode; the tow gathering mechanism is connected with the fixed-width slitting mechanism in a matched mode and controls gathering of the fixed-width slitting tows; the fixed-length slitting mechanism is connected with the tow gathering mechanism in a matched mode and controls the tows to be slit into tow sections in a fixed-length mode. Double-sided moisture regaining and/or feeding, fixed-width slitting, tow gathering and fixed-length slitting into tow sections with the width of 0.5 mm are completed, and the filling rate and sensory quality of cigarettes are improved.

Description

technical field [0001] The invention belongs to the technical field of processing equipment design and manufacture, in particular to a coiled strip wire forming system. Background technique [0002] The production process of the reconstituted tobacco leaves by the existing papermaking method is as follows: after soaking and extracting non-standard and available tobacco raw materials such as tobacco stems, tobacco powder and broken tobacco flakes, solid-liquid separation is performed to separate liquid soluble matter and solid insoluble matter, and separate the The solid insolubles that come out are beaten and made into fiber bases. After drying once, the separated liquid solubles concentrate is coated on the fiber bases, and after secondary drying, the banners are obtained. Shaped reconstituted tobacco leaves are sliced ​​and dried for three times, and then packed in boxes to obtain reconstituted tobacco leaves, so that the reconstituted tobacco leaves can be mixed with natu...

AI Technical Summary

Problems solved by technology

[0004] Although the reconstituted tobacco shreds disclosed in the prior art or patents have certain similarities, for example, the reconstituted tobacco leaves packed in boxes are unpacked, loosened, dampened, shredded, dried and blended, which to a certain extent unravels the process of reconstituted tobacco leaves in papermaking. The common processing of tobacco leaves and natural tobacco leaves has problems such as chipping, dust, flying fibers, and low utilization rate, but the following problems still have not been completely resolved:

[0005] (1) The shear strength, tensile strength and other characteristic indicators of reconstituted tobacco leaves by the papermaking method are quite different from those of natural tobacco leaves. It is easy to run when using the existing mainstream shredding machine, which requires a higher knife gate pressure, resulting in The cut tobacco is less loose;

[0006] (2) Paper-making reconstituted tobacco leaves are easy to run when shredded by the existing mainstream cutting machine, which affects the uniformity of the width of the shreds and the uniformity of the length of the shreds in the distribution of the cigarettes, and ultimately affects the quality of the cigarettes;

[0007] (3) The effective utilization rate of reconstituted tobacco leaves is low. According to the production test, the effective utilization rate of reconstituted tobacco leaves in the cigarette production process is about 85%. Part of the fiber is detached from the reconstituted tobacco leaves and becomes dust and tobacco dust, which not only affects the utilization rate of reconstituted tobacco leaves and the production efficiency of cigarette making machines, but also causes environmental pollution due to the spread of dust in the air; During the rolling process, the filaments are easily entangled and agglomerated, and are not easy to be loosened by the spinning roller of the cigarette making machine, resulting in part of the agglomerated filaments and draws being removed by the cigarette machine;

[0008] (4) At present, the traditional shredding process commonly used by cigarette enterprises is difficult to effectively control the consistency of cut tobacco width, while the length of shredded tobacco is mainly determined by the size of reconstituted tobacco leaves, and shredded tobacco that is too long or too short accounts for a large proportion , resulting in an uneven distribution of tobacco

[0009] In the Chinese patent with application number CN 202110298207.1, a roll-type strip wire making process is disclosed, but it does not describe the specific process equipment and open, so it is necessary to conduct further research on related process equipment
