FIG. 1 is a schematic structural diagram of an intelligent laser cutting device for the intelligent laser cutting treatment method of the bead blasting waste cigarette.
Detailed Description
The following examples are provided to further illustrate the present invention for better understanding, but the present invention is not limited to the following examples.
Example 1
The utility model provides a method that pearl blasting waste cigarette intelligence laser cutting handled, includes that cigarette ration is carried, cigarette preliminary screening and paves, intelligent laser cutting (including machine vision recognition device, stable adjustable speed's conveying system, laser cutting device, smog clean system), cigarette rubbing, pipe tobacco vibration screening process such as:
(1) a cigarette ration is carried, and this embodiment adopts the feeding machine of taking the feed bin, carries the waste cigarette on the vibration paving device according to controllable speed.
(2) Cigarette tentatively sieves and paves, the cigarette is carried on the shale shaker of vibration pave-up device by the feeding machine, the shale shaker is along a cigarette direction of transportation periodic vibration, make the cigarette advance the in-process can pave into the individual layer through the vibration effect as far as possible, the top of shale shaker still is provided with the baffle, the distance between the lower terminal surface of baffle and the shale shaker is between 1 ~ 2 times pipe tobacco height, the cigarette that avoids the overlap joint bridge gets into laser cutting district, because laser work focus is only about 1mm, behind the overlap joint bridge, lead to the laser easily and cut not to the cigarette surface outside the focus. The lower part of the vibrating screen is provided with a tobacco shred collecting tray used for collecting the tobacco shreds below the screen, and the tobacco shreds scattered in the vibrating process fall into the tobacco shred collecting tray below the vibrating screen to avoid being brought into the cutting belt to influence the height of the cigarettes.
(3) Intelligence laser cutting is by machine vision recognition device, laser cutting device, stable adjustable speed's conveying system, smoke purification system synergism:
the machine vision recognition device comprises an image collector and an image processor, wherein the image collector is an industrial camera, and the image processor can adopt an existing commodity processor. The industrial camera continuously and rapidly takes pictures to acquire image information of the cigarettes, the image processor receives the image information acquired by the industrial camera and compares the image information with the pre-stored image information to identify the positions of the cigarettes, the bobbin paper and the tipping paper and corresponding cutting paths. And (4) forming an optimal cutting path by connecting all sub paths through calculation, and conveying a cutting command to the laser cutting device by combining the conveying speed of the conveying belt. The cutting path can be set according to different forms of a single cigarette, for example, the cutting path of a bent cigarette can be a curve, and parts which do not need to be cut can be bypassed. The laser cutting device finishes the instruction of the machine vision recognition device through the rapid deflection of the vibrating mirror, thereby realizing accurate cutting. The stable speed-adjustable conveying system is necessary hardware for finishing dynamic continuous cutting and conveying cigarettes, and is also a bridge connecting a machine vision recognition device and a laser cutting device in a coordinate system. The path planning is dynamically conveyed to the laser cutting device through the uniform-speed transportation of the conveying belt, and the organic combination is finally realized, so that the requirement on the speed stability is high. During laser cutting, certain smoke is generated, so that a smoke purification system is required to be equipped.
(4) Rubbing cigarettes, namely rubbing cigarettes cut open along the axial direction, and slightly rubbing the cigarettes to enable the cigarettes to deform and lose wrapping property because the cigarettes still have certain wrapping property due to the shape of cigarette coil paper and the like. The cigarette kneading mode mainly adopts an upper layer kneading belt and a lower layer kneading belt which are in the same direction, the speed difference can be adjusted, and the kneading effect is achieved through the speed difference.
(5) The tobacco shreds are subjected to vibration screening, the kneaded cigarettes are effectively separated from the tobacco shreds, the bobbin paper, the filter tips and the like through the vibration screen, and the tobacco shreds are recycled.
After the bobbin paper is cut by the laser, the energy of the laser is basically exhausted, so that the cutting effect on the cut tobacco is small, and a small part, if any, is obtained, the artificial damage to the cut tobacco is small in the cutting process, and the recovered cut tobacco can be ensured to have high cut tobacco finishing rate by the aid of subsequent kneading control, screening control and the like. The laser cutting line has smooth edges, so cutting paper scraps are difficult to generate, and the only reason is that if a cigarette lap has a part which is not well bonded, when the laser happens to cut the part, the part which is not bonded can be possibly formed into filiform paper scraps to come out. Compared with the paper scrap generated by the hammering type waste smoke treatment mode, the proportion of the paper scrap is almost negligible.
While the foregoing is directed to the preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
