Filter tip cutting deviceTechnical Field
The invention relates to tobacco processing machinery, in particular to a filter tip cutting device.
Background
In the typical filter cigarette production process at present, the filter is one of the indispensable raw materials. Typically, filters are constructed from cellulose acetate, fiber webs, and other raw materials. In the production of filter-tipped cigarettes, the double length of filter tip must be placed centrally, the white cigarettes spliced on both sides, and then the filter tip and the white cigarettes wrapped with tipping paper to form the double length of filter-tipped cigarettes. Due to production efficiency and process requirements, the original filter length provided upstream is typically four or six times that of a single filter. It is therefore necessary to cut four or six times the length of the filter before splicing the white cigarettes, using a cutting device to cut it to the double length of the filter required in the above process. This slitting process is referred to as "four slitting" or "six slitting" of the filter.
When the filter tip is cut four times or six times, its cutting device has great difference to adapt to the needs of different brands, different specifications. Usually, when four-part cutting is carried out, only one cutter is needed for the cutting device. When six-slitting is performed, two cutters are generally needed. When cigarette manufacturers change cigarettes of different brands and different specifications (mainly relating to filter length specifications), the corresponding cutting devices must be replaced.
At present, cigarette making machines of mainstream in the market select four-slitting or six-slitting modes according to filter length specifications when filter cigarettes are produced. Four slitting is the basic mode. The main structure of the utility model comprises a cutter, a fixed bracket and a driving part. According to different configurations, some cutter devices are also provided with a knife grinder, a cutter safety protection cover and the like. Six are the extension of four cutting, are about to two four cutting devices, according to certain spatial position, the overall arrangement is near the filter tip cutting wheel. And the two four-slitting devices are staggered at a certain spatial distance in the axis direction. Although the six-cutting is the repetition of the four-cutting, when the length specification of the cigarette filter tip changes and needs to be converted between the four-cutting and the six-cutting, a great number of parts need to be disassembled and adjusted, which wastes time and labor.
When the cigarette specification changes, especially when filter length changes greatly, the existing filter cigarette production equipment needs to adjust or replace corresponding filter cutting equipment, adopts a four-cutting or six-cutting mode to cut, and finally cuts the filter with the length four times or six times into the double-length filter required by the process.
The filter tip cutting device of the existing mainstream equipment needs to carry out a large amount of manual work when the cutting mode is changed. The blade of the cutting device is connected with the driving part through the mounting and fixing bracket of the blade. And the blade and the driving part are respectively arranged on two sides of the wall plate of the host machine, and the driving part is arranged in a driving box body of the host machine. When the cutting device is replaced and installed, the whole machine is required to be shut down for safety, the main machine driving box body is disassembled, and the filter tip cutting device is installed.
Even if the length of the filter tip changes slightly, the operation of the main machine must be stopped, and the filter tip cutting device is adjusted. Due to the structure of the existing cutting device, the adjustment becomes complex and time-consuming, and is not beneficial to improving the production efficiency.
