Description

Roller screen and purification screen before waste cigarette treatment by using same Technical Field The invention relates to a roller shaft screen structure, in particular to a roller shaft screen and a purification screen before waste cigarette treatment. Background The main method for changing waste into valuables is to utilize a waste cigarette processor to take out cut tobacco from the waste cigarette. At present, three modes of waste cigarette treatment at home and abroad are mainly that firstly steam wets and flicks, secondly compressed air is used for blowing wires after the cigarettes are tidied, and thirdly, the cigarettes are oriented to be fully cut and half cut. The waste cigarette purification problem exists in any treatment mode. Because the waste cigarettes are mainly produced due to the faults of the rolling and connecting package production equipment, the faults are caused by a plurality of reasons, and waste paper, waste bars, waste adhesive tapes, tipping paper, conjoined cigarettes, broken cigarettes, bent cigarettes, bullet smoke discharge cigarettes and running cigarettes which are produced due to the faults coexist with standard cigarettes. At present, the waste cigarette impurity removal treatment method comprises the steps of manually picking up and removing large foreign matters, screening and removing small foreign matters, namely pouring the waste cigarettes into a groove body with sieve holes, screening and removing tobacco foam, and then entering a waste cigarette treatment machine, and also entering the waste cigarette treatment machine after the enterprises adopt huge winnowing screening and impurity removal, wherein winnowing noise is large, equipment occupation area is large, cost is high, and effects are not ideal. The roll shaft screen is also called a multi-stage linkage roll shaft screen, an equal-thickness screen, a mud-stone separator, a butterfly-shaped screen and the like, is suitable for separating various stone materials, and can be classified according to different proportions, sizes and shapes, so that the load of subsequent separation equipment is reduced. In 2012, the roller screen is firstly applied to tobacco sheet screening and tobacco shred screening by the company, and has great success in the field of tobacco screening because the roller screen has the advantage which is difficult to compare with a common vibrating screen. The cigarettes are thick, thin, long, short and bent, and are complicated with waste paper, buckling paper, waste rods and the like, screening is difficult by using a roller screen, no related study exists, and waste cigarette treatment needs a pretreatment device of a waste cigarette pretreatment process, especially a wire blowing type and sectioning type waste cigarette treatment device, and a pretreatment means of waste cigarette treatment is more urgently needed to ensure the yield and quality of waste cigarette treatment. Disclosure of Invention Aiming at the problems, the invention aims to provide a roller screen which solves the problems that the traditional screening process and tools cannot effectively screen or the screening efficiency is low in the field of waste cigarette screening. The technical proposal is that the device comprises a frame for installing the roll shafts, a screen frame, a power source and a transmission mechanism for driving each roll shaft to rotate, and a plurality of disc-shaped screen plates arranged on each roll shaft array, and is characterized in that the screen plates comprise a first screen plate with larger diameter and a second screen plate with smaller diameter than the first screen plate, the outer edge of the first screen plate is beyond the second screen plate and is close to the periphery of the adjacent roll shaft or the structure of the installation part of the adjacent roll shaft, the second screen plates are arranged among the first screen plates in an array mode, longitudinal screen holes which are in the same direction with the axial direction of the roll shaft are formed among the adjacent first screen plates, the outer edges of the second roll shaft and the adjacent roll shaft on the same roll shaft, transverse screen holes matched with the diameters of the strip-shaped materials are formed among the adjacent screen plates on the same roll shaft, and the sizes of the transverse screen holes and the longitudinal screen holes are not changed when the roll shaft rotates. In the above or some embodiments, the longitudinal screen holes on the same roller are on the same line or on different lines. In the above or some embodiments, the device further includes a third screen tray, the diameter of the third screen tray is smaller than that of the second screen tray, the outer edge of the array formed by the second screen tray on one roller corresponds to the outer edge of the third screen tray at the position of the adjacent roller, and the edges of the longitudinal screen holes are forme
