Abstract
The utility model relates to a cigarette machine aspiration pipe with adjustable wind speed, which comprises a wind pipe, flanges, a flowmeter and a damper, wherein, the flowmeter and the damper are connected in series through the flanges in the wind pipe. For the convenience of connection to a computer and automation control, the flowmeter is an orifice-plate flowmeter, and the damper is a 702Z-4I type electric butterfly valve or a 702Z-3R type pneumatic butterfly valve. The flanges on both ends of the aspiration pipe can be directly connected with an on-site wind pipe. Back installation, real-time wind speed can be calculated out by the computer according to output signals of the flowmeter, and be compared with a set value to output corresponding signals causing an electric or a pneumatic device to quickly adjust the opened/closed degree of the valve; wind speed errors can be stabilized within the range of about 1 m per second, and the wind speed is frequently kept in line with the set value. The utility model thoroughly solves the wind speed difference problem on a wind inlet of a shred collecting box caused by wind quantity change of a manifold and different lengths of branch pipes, and can be arranged in wind pipes of cigarette factories for conveying materials such as tobacco shreds, tobacco stems, tobacco leaves, etc.
Description
Technical field:
The utility model relates to the aspiration channel that a kind of cigar mill uses, and particularly the aspiration channel that is connected with strength wire distribution cigarette machine tobacco collecting box belongs to the mechanical field of making cigarette.
Background technology:
Strength wire distribution formula cigarette machine is because of its automaticity height, advantages such as the big and stable and reliable operation of output, now by tobacco productive corporation is widely-used both at home and abroad, each cigarette machine that these cigarette factories use need with pipe tobacco all be with negative pressure the pipe tobacco of wire feeder to be drawn into to take out automatically in the cigarette machine tobacco collecting box again to roll, because the platform number of cigarette machine is a lot, can not dispose blower fan and deduster respectively, common configuration is to be connected with deduster and blower fan with a house steward, many arms are housed on the house steward to be connected through the inlet scoop of flange with each cigarette machine collection smoke box respectively, but these arms are common airduct, lack the ability of regulating wind speed, inhaling the silk wind speed mainly regulates by house steward, but because the installation site difference of each cigarette machine, the arm that is connected with house steward has the long weak point that has, the resistance difference that arm is produced wind speed, must cause the wind speed of each the cigarette machine tobacco collecting box inlet scoop in the pipe network to vary, depend merely on the wind speed of regulating main valve and can not solve the inconsistent problem of wind speed in the pipe network.Again because every cigarette machine is to carry out work or shutdown according to producing needs; even the cigarette machine in operate as normal on the production line also need often be changed in supplying silk and suspending for the state of silk; make house steward's air quantity be in the state of fluctuation always; more strengthened the wind speed difference that needs for the tobacco collecting box air inlet place of silk; so; obviously there is the unstable and inconsistent problem of the wind speed that is difficult to overcome in existing pipe network, and causes the interior wind speed of arm on the pipe network even can reach 50% difference.Because of change of wind velocity can directly influence cigarette quality, for the low excessively arm of wind speed, cigarette machine the fracture phenomenon can occur and influence the output of production; For the too high arm of wind speed, the pipe tobacco that is transferred can produce a large amount of broken silks, when serious, can be to the broken rate of pipe tobacco up to more than 8%, and the increase of broken rate will have a strong impact on the quality that tobacco product props up.
Summary of the invention:
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and it is different in size and cause the wind speed difference problem at tobacco collecting box air inlet place thoroughly to solve fluctuation of house steward's air quantity and arm, designs the adjustable cigarette machine aspiration channel of a kind of wind speed.
The adjustable cigarette machine aspiration channel of wind speed of the present utility model comprises airduct and flange, also includes a flowmeter and a damper, and described flowmeter and damper are serially connected in the airduct through flange.For the ease of being connected with computer, realize automation control, described flowmeter is selected orifice-plate flowmeter for use, and damper is selected 702Z-4I type electric butterfly valve or 702Z-3R type Pneumatic butterfly valve for use.
Advantages such as the adjustable cigarette machine aspiration channel of wind speed of the present utility model has reasonable in design, and is easy to install can be used as independently product production in a large number in factory, during to on-the-spot the installation, can directly be serially connected in the arm through flange.Owing on every cigarette machine tobacco collecting box air draught arm, the adjustable cigarette machine aspiration channel of wind speed has been installed respectively, as long as house steward's wind-force is enough, every wind speed in the cigarette machine tobacco collecting box is stabilized in the setting range, it is different in size and cause the wind speed difference problem at tobacco collecting box air inlet place thoroughly to have solved house steward's air quantity fluctuation and arm, be adapted at most using in the airduct that pipe tobacco carries, also be adapted at using in the airduct of mass transport such as offal and tobacco leaf, further improve cigarette quality for cigarette factory and created good condition.
Description of drawings:
Accompanying drawing is the structural representation of an embodiment in the utility model.
The specific embodiment:
Referring to accompanying drawing, the adjustable cigarette machine aspiration channel of wind speed of the present utility model comprises airduct 1 and flange 2, also includes a flowmeter 3 and a damper 4, and described flowmeter 3 and damper 4 are serially connected in the airduct 1 through flange 2.Among the figure 5 is the sealing rings on flowmeter or the control valve.For the ease of being connected with computer, realize automation control, described flowmeter 3 is selected orifice-plate flowmeter for use, and damper 6 is selected 702Z-4I type electric butterfly valve or 702Z-3R type Pneumatic butterfly valve for use.The flange at aspiration channel two ends can directly be connected with on-the-spot airduct.After the installation, the signal output part of the differential pressure pickup on the flowmeter 34 is connected with the simulate amount input of computer, the signal input part of the electronic or pneumatic means on the damper 4 is connected with the simulation signal output part of computer, being available computers calculates real-time wind speed according to the output signal of flowmeter, through comparing with setting value, it is exportable corresponding signal, make the switching degree of the electronic or pneumatic rapid control valve of actuating unit, wind speed can be stabilized in error and be in the scope of per second ± 1 meter, make wind speed often and setting value be consistent.
Claims (2)
