Adhesive-free strip splicing device

Abstract

The invention provides an adhesive-free strip splicing device, which comprises a rack, and a transposition strip disc, an adhesive-free splicing mechanism, a new strip passing wheel set and an old strip passing wheel set which are arranged on the rack, and is characterized in that a first deviation rectifying mechanism is arranged on a new strip running path at the input end of the adhesive-free splicing mechanism, a new strip end acceleration winding mechanism is arranged on the new strip running path at the output end of the adhesive-free splicing mechanism, meanwhile, an old strip cutting and adsorbing mechanism is arranged on the adhesive-free splicing mechanism and located on an old strip running path, and a second deviation rectifying mechanism is arranged on a working strip path at the output end of the adhesive-free splicing mechanism. It can be guaranteed that the dislocation amount is within the range of + / -0.5 mm when new and old paper strips are connected, and it can be guaranteed that the transverse offset of the paper strips is within the range of + / -0.5 mm in the online conveying process. The device is high in accuracy, reliability and stability, the equipment stability can be improved, the product quality is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to a strip material glueless splicing device, which is especially suitable for use in the tobacco industry and belongs to the technical field of mechanical equipment design and manufacture. Background technique [0002] At present, most of the tipping papers of mainstream medium and low-speed splicing units in the market are supplied by their own semi-automatic disc changing devices. Each (set) splicing unit generally has two tipping paper trays, that is, used paper tray and new paper tray. After the old paper is pulled out from the old paper tray installed on the online unwinding reel, it passes through the brake system of the online unwinding reel, the wheel set, the limit ring, the splicing device, scraping paper shaping, surface gluing, heating, and manual deviation correction After the new paper is pulled out from the new paper tray installed on the spare unwinding shaft, it passes through the brake system of the spare unwin...

Problems solved by technology

However, due to the actual layout and positioning technology, the effect of axial positioning of new paper and old paper through the positioning shaft before the splicing device is very limited, resulting in the splicing of the existing splicing device. There is an obvious amount of misalignment in old paper, and the amount of misalignment can reach ±3.0mm or more at most. This amount of misalignment will directly lead to serious quality defects in finished cigarettes, or bring obvious waste of raw and auxiliary materials; In the splicing technology, there is more or less a certain length of free paper tape at the front and rear ends of the tipping paper. When the free paper tape is subsequently cut by the slitting drum, there will be a greater possibility of Discrete shreds of paper are formed, and the shreds will drift uncontrollably and disorderly in the equipment, which will easily cause the paper board to be blocked, and then cause the equipment to stop, which seriously reduces the effective operation rate of the equipment and significantly increases the cost of production. Consumption and waste of auxiliary materials; at the same time, because the tipping paper supply process is a long-distance transport, the tipping paper may be damaged due to uneven tension of the paper tape, deflection of the tipping paper tray, and the deviation of the paper tape itself. Axial offset occurs, and there is one and only one manual correction device between the assembling device and the cutting drum, which cannot ensure that the real-time position of the paper tape is within a reasonable range, which may lead to serious quality of the finished cigarettes defect
