Description
Technical Field
The utility model relates to a cigarette filter rod processing technology field, in particular to silk bundle conveyor and opener.
Background
The cigarette filter stick is usually made by applying plasticizer to polypropylene fiber or acetate fiber tow (tow for short) and rolling with paper after molding. The tow is usually provided in the form of a tow bag after being packed, the tow in the tow bag is layered and stacked in a zigzag manner, and the tow is compressed and compacted in the packing process, so that the air permeability of the tow is poor. Therefore, the tow needs to be opened before the filter rod is formed, so that the tow becomes loose. In the prior art, a tow opener entering a filter rod forming device firstly blows off tows by using high-pressure airflow or staggers and separates the tows under certain tension through an opening roller to uniformly spread the tows, and the tows are sprayed with plasticizers such as glycerol after being opened to harden the tows to form a filter tip.
The good and bad tow opening effect directly influences the stability of the filter stick suction resistance, and the filter stick suction resistance refers to the suction resistance generated by the air permeability of the filter stick in the process of smoking cigarettes. The filter stick resistance stability is the most key quality control index of a filter stick product, and whether the filter stick product is stable reflects whether the quality of cigarettes is uniform and stable. If the filter stick has poor suction resistance stability, the cigarette tastes are different, and part of cigarettes can not meet the tar reduction requirement of the label.
The research of cigarette factories shows that whether the tows can stably enter the opener has great influence on the opening effect of the tows. In the prior art, the feeding speed of the opener is high, and tows can jump in the vertical direction and the horizontal direction before entering the opener, so that the tows entering the opener are inclined, wrinkled or deviate out of the opening roller, the uniformity of tow opening is greatly influenced, and even the tows are broken.
In addition, glycerol detection is needed before and after the tows are opened, namely the tows penetrate through the microwaves before entering the opener to obtain a first voltage feedback value, the tows are sprayed with glycerol after being opened and are shaped, the tows penetrate through the microwaves again to obtain a second voltage feedback value, the second voltage feedback value is fed back to be subtracted from the first voltage feedback value, and the glycerol spraying amount is obtained through calculation of the difference value. If the tow is not conveyed stably, the accuracy of the first voltage feedback value is greatly influenced, and further the glycerol spraying amount cannot be accurately detected, so that the addition amount of the tow glycerol is difficult to control, various indexes such as the suction resistance and the filtering capacity of a finished filter stick product are influenced, and the product quality is reduced.
In conclusion, solving the problem of unstable tow conveying is very important for improving the quality of the filter stick.
