Description
Technical Field
The invention relates to a cutting device, in particular to a strip cutting device, and belongs to the technical field of design and manufacture of strip processing equipment.
Background
The existing strip slitting equipment has some defects in the using process, and brings about a lot of troubles for users. For example, chinese patent application publication No. CN 109090684A discloses a "tobacco cutting device and process for reconstituted tobacco without burning by heating", which completes the cutting of reconstituted tobacco without burning by rotating the cutting edge of the knife roller and the supporting member of the smooth roller as the lower 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 connection 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, a chinese patent application with publication number "CN 110063517A" discloses "an on-line shredding and forming device for a base rod of a paper smoking segment of a novel sheet for tobacco", in which a cutter roller and a smooth roller are used to match each other to complete the slitting of a band, and the smooth roller used in the application is made of hard plastic or flexible rubber, although the damage to the blade can be reduced, the following disadvantages exist: (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 over-speed 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 filament bundle is easily broken.
For another example, chinese patent application with publication number "CN 108669628A" discloses "a reconstituted tobacco shredding device and its shredding mechanism", 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 arranged in the gap between two adjacent belts, 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.
