Description
Technical Field
The invention relates to a slitting device, in particular to a strip constant-width slitting device, which belongs to the technical technology of design and manufacturing of strip slitting equipment.
Background
The coiled strip slitting device is a mechanism capable of slitting thin sheets, coiled materials, strips and the like in a fixed width mode, but the conventional strip slitting mechanism has some defects in the use process, and brings certain trouble to users:
for example, chinese patent application publication No. CN 109090684A discloses a shredding device and shredding process for heating non-burning reconstituted tobacco, and the shredding of heating non-burning reconstituted tobacco is completed by the cooperation of a sharp cutting edge on a rotary cutter roller and a supporting piece with a low roller as a smooth roller, and the following problems exist in this way: (1) The knife roller and the smooth roller are in direct contact to completely cut off the strip, so that the service lives of the knife roller upper blade and the supporting smooth roller are obviously reduced, the requirements on the processing and manufacturing precision of the knife blade are higher, and the knife roller and the smooth roller are not in contact to completely cut off the strip, so that the tows have burrs and the tows are adhered, and the filament forming quality of the tows is affected; (2) The cut filament bundles are easy to wind on a rotary knife roll or a smooth roll, especially when broken filaments occur, the filament bundles are easy to wind, the strip materials are wasted lightly, and the production safety accidents are caused heavily; (3) The cutter roller and the smooth roller are matched and connected, so that the processing and assembling difficulties of the blade are increased, and the production cost and the manufacturing cost are increased; (4) The cut tows can cause the problems that the too-tight tows are easy to break, the too-loose tows are easy to disorder and easy to block and the like due to the fact that part of tows are loose and part of tows are too tight in the conveying process.
For another example, chinese patent application with publication number of CN 110063517A discloses an on-line shredding and forming device for a novel base rod of a paper fuming section of a sheet for tobacco, which also uses a cutter roller and a smooth roller to match and complete slitting of a strip, and the smooth roller used in the application is made of hard plastic or flexible rubber, although damage of a blade can be reduced, the following drawbacks also exist: (1) The cutter roller is always contacted with the supporting smooth roller in the slitting process, so that the service life of the supporting smooth roller is drastically reduced, the service life of the cutter roller is also reduced, and particularly, the cutter roller is particularly obvious in high-speed slitting; (2) The supporting smooth roller is made of flexible materials, the friction resistance is high, the overspeed slitting resistance of the cutter roller is high, and meanwhile, the supporting smooth roller and the strip material must be kept at the same speed, otherwise, the filament bundles are easily broken.
For example, in chinese patent application with publication number of CN 108669628A, a reconstituted tobacco shredding device and a shredding mechanism thereof are disclosed, shredding of reconstituted tobacco is completed by cooperation of a hob and a conveyor belt, the conveyor belt has a supporting function, the hob is arranged in a gap between two adjacent belts, and the disadvantage of the mode is that: (1) The conveyer belt has elasticity, and the stress of the belt material in the slitting process can lead the conveyer belt to deform and give way, so that the belt material can not be slit or the dimension error of the slit belt material is larger; (2) The method is only suitable for cutting tows with larger widths, when the required tows have smaller widths, such as 1mm and 2mm, the tows are difficult to cut, and the requirements of the tows with smaller widths cannot be met.
There is a need for improvements in the art to meet the increasing demands of tobacco enterprises for tows.
