Abstract

The utility model relates to a tobacco processing machine, particularly a wind speed stabilizer of a pneumatic shred feeder for a cigarette machine. The wind speed stabilizer mainly comprises shred feed pipes connecting the shred feeder with blanking devices of the cigarette machine, a main wind pipe connected with a blower and a dust collector, and a plurality of draft branch pipes connected between the main wind pipe and the blanking devices of the cigarette machine, wherein, the draft branch pipes are provided with flowmeters and electric disc valves; the input end of a controller is connected with the flowmeters, and the output end is connected with the electric disc valves. The main wind pipe on the front part of the dust collector is connected aside with branch pipes which are communicated with atmosphere and are also provided with electric disc valves connected with the output end of the controller. The utility model can dynamically regulate the systematical wind speed, so the opening degree of the electric disc valves in the draft branch pipes can be accurately regulated when the cigarette machine lies in the random operating state, so that the wind speed of the shred feeder can reach a steady value to minimize crushed tobacco shreds.

Description

The wind speed stabilising arrangement of Pneumatic silk feeding machine

Technical field

The utility model relates to a kind of machine for processing tobacco, especially relates to a kind of wind speed stabilising arrangement that is used for the Pneumatic silk feeding machine of cigarette machine.

Background technology

Adopt the Pneumatic silk feeding machine that pipe tobacco is sent into cigarette machine, can realize totally-enclosed conveying, because of having the automaticity height, and can produce the cigarette of a plurality of brands simultaneously, also can change advantages such as cigarette brand at any time, used by More and more factories at present.But the employing Pneumatic silk feeding in the wire feed process, is that a typhoon machine uses for several cigarette machines, when several cigarette machines can not be inhaled thread simultaneously, will cause the fluctuations in wind speed of wire-feeding pipe bigger, and wind speed is low, can cause for a silk quantity not sufficient; And the wind speed height will increase the broken rate of pipe tobacco again.At above-mentioned wire-feeding pipe wind speed problem of unstable, traditional wind speed stabilising arrangement is to open a bypass on the air main on the cleaning shaft of deduster front, mixes the gravity control valve, regulates wind speed by the aperture of regulating the gravity control valve and changes; Another kind of traditional wind speed stabilising arrangement is to open a bypass on the exhausting arm of every cigarette machine wire-storing storehouse, bypass pipe is adorned an air door, the electronic dish valve of this air door and wire-storing storehouse is an interlocked relationship, regulating wind speed by the switch of damper changes, though above-mentioned two kinds of structure wind speed stabilising arrangements can play a role to stablizing wind speed, but the wind speed to the cigarette machine change at random can't carry out dynamic adjustments, and can not satisfy instructions for use.And as CN2431734Y disclosed " the wind speed stabilising arrangement of Pneumatic silk feeding machine ", be that a side at the exhausting arm is equipped with air draught and manages partially, establish a throttle opening adjustable plate and a butterfly valve that opens and closes by cylinder in the inclined to one side pipe of air draught, when wherein one or several cigarette machines stop to inhale silk, then close the butterfly valve on its exhausting arm, open the butterfly valve of the inclined to one side pipe of its air draught, thread attitude is inhaled in simulation, so that wind speed is stable.But the wind speed stabilising arrangement of this kind structure enters the windage of exhausting arm and the windage of air main differs bigger from the inclined to one side pipe of air draught, in fact be difficult to the wind speed in other exhausting arm is regulated, be subjected to the position difference of each cigarette machine in addition and make wire-feeding pipe apart from difference, cigarette machine is in the course of work at random, windage in the whole wire feeder is constantly to change, and therefore can't realize the stable of wire-feed motor wind speed.

Summary of the invention

The purpose of this utility model provides a kind ofly can dynamically regulate wind speed, to keep the wind speed stabilising arrangement of the stable Pneumatic silk feeding machine of wind speed.

The utility model for the technical scheme that achieves the above object is: a kind of wind speed stabilising arrangement of Pneumatic silk feeding machine, comprise the wire-feeding pipe that wire-feed motor links to each other with each cigarette machine feeder, the air main that links to each other with blower fan and deduster, be connected several exhausting arms between air main and each the cigarette machine feeder, it is characterized in that: flowmeter and electronic dish valve are housed on described each exhausting arm, the input termination flowmeter of controller, the electronic dish valve of its output termination, the other arm that communicates with atmosphere that connects on the air main of deduster front portion, electronic dish valve also is housed, the electronic dish valve of the output termination of controller on the arm.

Operation principle of the present utility model is: when Pneumatic silk feeding device that n platform cigarette machine is formed, the required total blast volume of system was Q when n platform cigarette machine was inhaled thread simultaneously _nElectronic dish valve on the exhausting arm just has n aperture, n current signal promptly arranged, to any one state, as long as the current signal that input is corresponding, just can give the needed total blast volume of fixed system, but owing to being uneven in length of each cigarette machine and fiber tube, its resistance does not wait yet, again because total blast volume is not that mean allocation is given n platform cigarette machine, can detect air quantity this moment by the flowmeter on every cigarette machine exhausting arm, output current signal is delivered to controller, by after the signal processing, exports corresponding current signal in controller, control the aperture of electronic dish valve and carry out fine tuning, to realize the constant of wind speed.

After the utility model adopts technique scheme: because flowmeter and electronic dish valve are housed on each exhausting arm, air main also is equipped with electronic dish valve, at first carry out in a basic balance to system's total blast volume by the electronic dish valve on the control arm, dynamically the wind speed in the exhausting arm is separately detected by each flowmeter again, and the current signal that detects passed to controller, after by controller signal being handled, export corresponding current signal, control the aperture of electronic dish valve in each exhausting arm, when cigarette machine is at random duty, can accurately regulate the aperture of the electronic dish valve in each exhausting arm, make the wind speed of wire feeder reach a stable speed, its wind speed can be controlled in ± 1s/m between, reduce to minimum with making of pipe tobacco is broken.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.
