Abstract

The utility model provides a self-clean device of broken ends sucking case for a spinning frame, which can effectively clear accumulation fiber of different thickness through regulating span for spinning production. The utility model is characterized in that a rotary apron 6 is sheathed outside a tooth pattern main shaft 5; the rotary apron 6 keeps close to a screen of a cylinder mould 1; rollers 7 constricts one side of the rotary apron 6 in parallel, making the apron 6 keep close to the screen; the rotary apron 6 rotates in an opposite direction to the running direction of the cylinder mould 1. When coming into contact with the rotary apron 6, the accumulation fiber is driven into by the rotary apron 6 and is compulsorily discharged into a storage tank under the grasp and support of a jaw composed of rolls 7.

Description

Self-clean device of broken ends sucking case for spinning frame

The utility model be a kind of produce about spinning in the broken end inlet box self-cleaning device of fine spining machine, particularly a kind of revolution apron filter screen self-cleaning device can be used for the spinning machinery of all kinds of broken end inlet boxs.

Fine spining machine broken end suction apparatus is that the yarn that is spued by front roller after utilizing air-flow with spinning end breaking sucks in cotton suction duct (flute pipe) aperture at present, accumulates in the inlet box through blast main again.In the middle of inlet box one deck filter screen is arranged, be used to gather the broken end fiber of suction, another side is equipped with a centrifugal fan, and the flute pipe will have the cotton effect of good suction, necessarily requires to inhale hole vacuum height.In spinning process, along with the increase of broken end number of times, the fiber thickness that gathers on the filter screen increases, and the resistance that air-flow sees through filter screen also increases gradually, thereby negative suction can reduce the inhalation rate of influence broken end fiber.Need just can make blast main keep certain negative suction often by manually stripping the fiber that accumulates on the filter screen for this reason, compare trouble like this, not note to influence the cotton effect of suction slightly.

G5/1 type fine spining machine through investigation Switzerland Rieter company, used broken end inlet box automatic cleaning apparatus (see figure 1), in the broken end inlet box, be provided with the revolution cylinder mould, at a cylinder mould periphery a corner trash discharging apparatus is arranged, when screen surface is gathered the certain thickness fiber, because cylinder mould turns round automatically, accumulations such as fiber are just discharged outside the broken end inlet box by trash discharging apparatus.But the fixing distance of peeling off between the raised points of gathering fiber and filter screen is bigger, when gathering fiber thickness less than 3 millimeters, owing to gather the raised points that fiber fails to touch trash discharging apparatus on the filter screen, gathers fiber and still stays on the filter screen and make.See " the RY5 type fine spining machine operation instructions of Japanese Toyota Company " again, in the broken end inlet box, also showed cylinder mould self-cleaning device (see figure 2) of the same type, designed a pair of stripper roller in cylinder mould one side, but and distance is very near between filter screen, the angle of wedge that filter screen and stripper roller are formed is less, the also unfavorable eliminating of gathering fiber.

The purpose of this utility model is to overcome the deficiency of above-mentioned two kinds of broken end inlet box filter screen self-cleaning devices, and a kind of novel fine spining machine broken end inlet box self-cleaning device is provided.

Feature of the present utility model is: described device utilizes prior art cylindrical shape cylinder mould, and other designs a pair of pressure roller and revolution apron mechanism, and distance is regulated by the apron pin between revolution apron and filter screen, can suit to remove different-thickness and gather fiber.Cover groove main shaft in the revolution apron, main shaft two ends are inserted in the cradle device that supports apron presses close to filter screen, and gyratory directions is opposite with cylinder mould.The parallel revolution apron outside that compresses of pressure roller, groove main shaft and pressure roller are installed in respectively on the box-frame of broken end inlet box.

The utility model has the advantages that having overcome prior art can not thoroughly remove the shortcoming of gathering fiber on the filter screen, utilize the softness of apron can press close to filter screen, can effectively remove and gather fiber, do not damage filter screen again, improve cleaning effect.

Fig. 1 is a Switzerland G5/1 type fine spining machine self-cleaning device schematic diagram; Fig. 2 is Japanese RY5 type fine spining machine self-cleaning device schematic diagram; Fig. 3 is the utility model self-cleaning device schematic diagram; Fig. 4 is the utility model self-cleaning device profile; Fig. 5 is the utility model self-cleaning device perspective view.Among the figure:

1, cylinder mould (surperficial single filter screen) 2, division board

3, cradle 4, apron pin

5, groove main shaft 6, revolution apron

7, pressure roller 8, gear

9, sprocket wheel 10, motor

11, bearing 12, trash discharging apparatus

13, stripper roller

In conjunction with the accompanying drawings most preferred embodiment of the present utility model is described in detail: the filter screen of cylindrical shape cylinder mould 1 can adsorb and gathers fiber, and division board 2 is used to stop the absorption of isolated area inner accumulated fiber on filter screen, and motor 10, sprocket wheel 9 are prior art.Cover groove main shaft 5 in the revolution apron 6, two ends of rotary main shaft 5 are inserted in cradle 3.Apron pin 4 two ends are with holes, and are fixed by bolts on the cradle 3, with the common tensioning revolution of groove main shaft apron 6, form a pendular body.Can regulate spacing during assembling with filter screen.Groove main shaft 5 drives revolution apron 6 and turns round with the reverse movement direction of cylinder mould 1.The pressure roller 7 parallel outsides that are pressed on the revolution apron.Groove main shaft 5 is linked by sprocket wheel 9 and one group of gear 8 with pressure roller 7, and is installed on the box-frame of broken end inlet box by bearing 11 respectively.

Cylinder mould 1 main shaft is intermittently rotated by motor 10 controls, gathering fiber on the filter screen touches when turning round apron 6., make by the friction of apron and to gather fiber and from filter screen, peeled, import between revolution apron 6 and the pressure roller 7, under the common gripping of revolution apron 6 and pressure roller 7, import in the storage bin.Filter screen is self-cleaning to finish, and cylinder mould stops operating, and treats repetitive operation next time.

Claims (2)

1, a kind of fine spining machine broken end inlet box self-cleaning device of forming by cylinder mould 1, division board 2, sprocket wheel 9, motor 10 and stripping device, it is characterized in that described self-cleaning device also comprises revolution apron 6 and the pressure roller 7 that can regulate with cylinder mould 1 spacing, revolution apron 6 is placed on the groove main shaft 5, two ends of main shaft 5 are inserted in cradle 3, cradle 3 is provided with the apron pin 4 of tensioning revolution apron 6, and cradle 3 is fixed on the machine frame of broken end inlet box.

2, self-cleaning device according to claim 1 is characterized in that the described pressure roller 7 that is pressed on revolution apron 6 one sides carries out transmission by gear 8.
