The present invention relates to a kind of row-type cotton gatherer for back chamber of carding machine by intermittent suction.
At present, in the separate unit cotton gatherer for back chamber of carding machine by intermittent suction (see figure 3) that use in indivedual cotton mills, it is made up of induced-draught fan 5, dust cage 6, sleeving valve 20, electromagnetic valve 8, controller 11, air pump 12 etc.This device one cover control 24-32 platform carding machine.Its course of work is as follows: cotton dirt is fallen cotton mouthful 2 places of collection by funnel 1, and instrument 11 to be controlled sends instruction to certain carding machine, by control line of electromagnetic valve 10, make electromagnetic valve 8 commutations, the sleeving valve 20 of this valve control is in exhaust condition, and the compressed air in the sleeving valve 20 is promptly emitted, and this sleeving valve 20 is opened.The cotton at cotton mouthful 2 places of collection is mixed through sleeving valve 20, inhales branch air duct 3 down, and following suction main air duct 4 enters induced-draught fan 5, delivers in the dust cage 6 again, most of cotton assorted ground of being shelled, and remaining air enters chimney in atmosphere.After when inhaling, having arrived, controller 11 sends instruction again makes it finish said process to second carding machine, meanwhile, controller 11 sends instruction and makes one by electromagnetic valve 8 commutations, the compressed air that this electromagnetic valve 8 extrudes air pump 12 enters sleeving valve 20 by compressed air line 9, and this sleeving valve 20 is closed.This carding machine is inhaled noil and is promptly stopped.Treat one circulated after again the exploitation.The shortcoming that said apparatus exists is: the first, each carding machine is by a sleeving valve and a solenoid control, and valve is too many, and maintenance load is big.The second, the structures shape of sleeving valve 20 itself this valve because of the gum cover endoporus directly by cotton assorted (cotton assorted with the speed about 10 meter per seconds by), easily make the gum cover wearing and tearing, this valve pocket is too short service life, is generally about two months.Especially sleeving valve has broken that to equal the total system sleeving valve all out of control, and promptly carding machine just is in the state of being inhaled entirely in the total system, and because of wind-force is too little, thereby noil can not be sucked away.Three, power consumption is big.For above-mentioned reasons, this device is not applied in the cotton mill.
It is obvious to the purpose of this invention is to provide a kind of power savings, simple in structure, the row-type cotton gatherer for back chamber of carding machine by intermittent suction that reliability is high.
The present invention is achieved in that
It is to improve on the basis of separate unit cotton gatherer for back chamber of carding machine by intermittent suction and realize.At first must solve following three problems, could realize the separate unit list suction row of changing into the formula of having a rest is intermittently inhaled.The first, the structure of former sleeving valve is not suitable for row's formula and intermittently inhales, and it utilizes the gum cover radial elastic to be out of shape and realizes valve switch.It is unsuitable for the bigger air channel of sectional area like this, and the impurity in the air channel is direct and the wind speed friction of rubber gum cover generation per second more than 10 meters, and service life is extremely short.Therefore must design new valve finishes the task that row's formula is intermittently inhaled.The applicant has designed, and a kind of " low pressure rubber door valve " applied for the Chinese patent (patent No.: 88221067.5).Its valve body is installed in outside the air channel, (structure that promptly cotton assorted passage and gum cover separate), and the big I of valve cross section, road and changing with the wind.
The second, blowing device makes that static cotton assorted to become dynamic cotton assorted before the design.Cotton mouthful of cotton of locating of collection mixed when being inhaled, also blown, thereby improved pick-up performance greatly.
Fast cyclic program when three, adopting short suction the, row's formula are inhaled and are different from the separate unit suction, and when separate unit was inhaled, if collection is plugged for cotton mouthful, increasing air draught power just can siphon away.And row's formula is when inhaling, and at cotton mouthful of place of collection of this row's carding machine, if there are several or all blocked by cotton is assorted, when strengthening air draught power, can only inhale out a certain, and then remaining can not be opened by suction greatly because of windage.Fullly just inhale cotton mouthful of collection is stifled and be exactly the noil that do not wait cotton mouthful of collection during short the suction, make the resistance of cotton mouthful of collection of each carding machine close, can guarantee like this noil of cotton mouthful of collection is exhausted.Finish above-mentioned idea, must shorten when inhaling, could accelerate circulation.The present invention is 20 seconds when adopting every row to inhale, if ten rows are arranged, the time spent of circulating each time is 200 seconds.
On the basis of the above, the present invention specifically is made up of induced-draught fan, electromagnetic valve, low pressure rubber door valve, air pump, controller, dust cage and a preceding blowing apparatus that acts on cotton assorted funnel porch.Every row's carding machine has only a low pressure rubber door valve and a solenoid control, and controller is successively by the action of row by solenoid control low pressure rubber door valve.Preceding blowing apparatus is by hair-dryer, and low pressure rubber door valve and breezeway are formed, the low pressure rubber door valve of air draught under blowing reached before every row's electromagnetic valve was controlled simultaneously.The program of fast circulation when controller adopts short the suction, every row is no more than 20 seconds when inhaling.
Below in conjunction with drawings and Examples the present invention is further described.
