Description
Technical field
The present invention relates to production of cigarettes machinery fields, and in particular to a kind of cigarette filter stick clears up back-blowing device automatically.
Background technology
Filter bar for cigarette is delivered to downstream unit after being produced by filter-stick forming device under the action of compressed air, wherein conveying
Device is made of filter stick transmitter, conveyance conduit, filter stick receiving station, and compressed air in a steady stream constantly passes through filter stick from transmitter terminal
Conveyance conduit flows to filter stick receiving terminal, due to entire conveyance conduit is connected through a screw thread by the long steel pipe of 6 meters or so of several length
At and length be 50-300 meter, once filter most stick occur phenomena such as " cracking ", " deformation " in conveyance conduit, be easy for occurring
Filter stick blocks conveyance conduit problem.
Conventional Method of blockage removal is after finding that filter stick blocks, to be notified by the operative employee of filter stick transmitter in the prior art
Conveyance conduit is unloaded down from filter stick transmitter, filter stick receiving station, then is passed through compressed air by the operative employee of downstream machine together,
The filter stick blocked in conveyance conduit is produced by boasting and realizes and empties.This manner of cleaning up working efficiency is low, troublesome in poeration.
To solve the above problems, how some technologies related personnel efficiently carries out pipeline block clearing if beginning one's study.
CN201310070660.2 discloses a kind of quick treatment device that cigarette filter charge bar pipeline airvey system blocks, the device
Coordinated by solenoid directional control valve and air source processing unit and spray compressed air into conveyance conduit, is not required to stop when blocking to realize
Machine and dismounting conveyance conduit.But the structure because using driving cylinder with movable valve plug come realize conducting between through-hole and material transport hole or
Close, thus have that driving cylinder itself is difficult to overcome without buffer problem, lead to the problems such as position is inaccurate, and part easily damages
It generates.
Although there is regulation in industry, the conveying of filter stick must be carried out in closed environment, in actual production,
The tight requirements in conveyance conduit exit are tight not as conveyance conduit entrance, therefore the patent applied before applicant in this case
Number for ZL201510580790X one kind emptying conveyance conduit automatically, if using the exit of conveyance conduit, seem a little
" wasting one's talent on a petty job ", and one kind disclosed in ZL201510580790X empties conveyance conduit floor space relatively a little greatly automatically.
