Description
Technical Field
The invention relates to a slitting device, in particular to a strip fixed-width slitting device, and belongs to the technical field of design and manufacturing of strip slitting equipment.
Background
The roll type strip slitting device is a mechanism capable of performing fixed-width slitting on thin sheets, coiled materials, strips and the like, but the existing strip slitting mechanism has some defects in the using process and brings certain troubles to users:
for example, chinese patent application publication No. CN 109090684 a discloses a "tobacco cutting device and a tobacco cutting process for reconstituted tobacco that is not burned by heating", which completes the cutting of reconstituted tobacco that is not burned by heating by the cooperation of a sharp cutting edge on a rotary knife roller and a support member with a low roller as a smooth roller, and this way has several problems: (1) the knife roll and the smooth roll are in direct contact to completely cut off the strip, so that the service lives of the blade on the knife roll and the supporting smooth roll are obviously shortened, the requirement on the machining and manufacturing precision of the blade is high, the strip cannot be completely cut off if the knife roll is not in contact with the smooth roll, and tows have rough edges and are adhered to each other, so that the filament forming quality of the tows is influenced; (2) the cut tows are easy to wind on a rotary knife roller or a smooth roller, and are easy to wind particularly when the tows are broken, so that the tows are wasted if the tows are light, and production safety accidents are caused if the tows are heavy; (3) the matching of the knife roll and the smooth roll increases the processing and assembling difficulty of the blade, which leads to the increase of the production and manufacturing cost; (4) the problems that the over-tight tows are easy to break, the over-loose tows are easy to disorder and easy to block and the like are caused by the fact that part of the tows are loose and part of the tows are over-tight in the conveying process.
For another example, chinese patent application publication No. CN 110063517 a discloses "on-line shredding and forming equipment for paper smoking section base rod of novel sheet for tobacco", which uses a cutter roll and a smoothing roll to match each other to cut the strip, and uses a smoothing roll made of hard plastic or flexible rubber, which can reduce the damage of the blade, but has the following disadvantages: (1) because the cutter roller is always contacted with the supporting smooth roller in the slitting process, the service life of the supporting smooth roller is rapidly reduced, the service life of the cutter roller is also reduced, and the high-speed slitting is particularly obvious; (2) the supporting smooth roller is made of flexible materials, the friction resistance is large, the overspeed cutting resistance of the cutter roller is large, and meanwhile, the supporting smooth roller and the strip material must keep the same speed, otherwise, the tows are easily broken.
For another example, chinese patent application with publication number "CN 108669628A" discloses "a reconstituted tobacco shredding device and a shredding mechanism thereof," which completes the shredding of reconstituted tobacco through the cooperation of a hob and a conveyor belt, the conveyor belt plays a supporting role, the hob is disposed in the gap between two adjacent belts, and the disadvantage of this method is: (1) the conveying belt has elasticity, and the stress of the belt material in the slitting process can cause the conveying belt to deform and yield, so that the belt material cannot be slit or the size error of slitting is large; (2) the device is only suitable for cutting tows with large width, and when the needed tows are small in width, such as 1mm and 2mm, the tows are difficult to cut, and the requirements of cutting the tows with smaller width cannot be met.
There is therefore a need for improvements in the prior art to meet the higher requirements of the tobacco industry for strands.
