Description

The device that textile fiber material transfer roller in the machine is kept clean

The present invention relates to a kind of device that textile fiber material transfer roller in the machine is kept clean, this device comprises that a suction pipe and is the stripping cutter.

In operating process, fiber, worm dirt and/or some other impurity get on through the textile fiber material transfer roller that regular meeting adheres in the machine.Often to place a stripping cutter at work, make it to contact, so that these materials are divested from roller with roller.Simultaneously, near the suction pipe that roller, will be arranged in parallel, suction pipe has an elongated slot, will divest the material that gets off by this groove and drain.Suction pipe, especially stripping cutter must periodically clean (entrained impurity and fiber removal are fallen).Because in most of the cases, near the free space in the machine roller is very narrow and small, so this cleaning often bothers very much.

The object of the present invention is to provide a kind of device of the above-mentioned type, adopt this device can be rapidly, easily stripping cutter and suction pipe are cleaned.

The objective of the invention is to finish like this: the stripping cutter is installed near suction pipe.Suction pipe has guide element, and it can move on a guiding device, and guiding device is installed on the machine.Guided procedure is carried out like this: stripping power and suction pipe can be released from machine, also can be used as integral body and are pushed and get back in the machine.

Advantage of the present invention is fairly obvious: clean because stripping cutter and suction pipe can whole be released from machine, thereby make the confined space in the machine no longer constitute influence to cleaning.After the outside of machine is cleaned, again their integral body is back in the machine, and rely on and to be connected and suitably to be fixed.

Suction pipe preferably includes a cannelure in the face of roller, and it preferably can be done rotation with respect to the stripping cutter and regulate.By regulating the width that suction pipe can change suction socket, promptly change the distance between the edge of groove in the free edge of stripping cutter and the suction pipe.

In operating process, if can the stripping cutter be pressed on the surface of roller by means of elastic force, just can obtain the good effect of keeping a public place clean, at this moment, the stripping cutter is fixed in the supporting arrangement in the mode of pivot suspension, supporting arrangement is fixed in the suction pipe, and the stripping cutter applies an elastic load with respect to supporting arrangement along direction of rotation.The value of elastic load is preferably adjustable.

Guiding device can be fixed in the machine with respect to the mode of roller with lateral adjustments, thereby the distance between suction pipe and the roller can be changed.By regulating guiding device, elastic force also changes simultaneously, and in operating process, the stripping cutter on the suction pipe is compressed against on the side face of roller.

An embodiment who has represented apparatus of the present invention in the accompanying drawing synoptically, wherein:

Accompanying drawing 1 is a cutaway view of this device;

Accompanying drawing 2 is right views of Fig. 1;

Accompanying drawing 3 is left views of Fig. 1.

Shown in dotted lines in Figure 1 is the outline line of roller 1.Roller 1 pivotably is bearing in (not shown) in the machine, and matches with at least one counter-rotating roller (also not shown), so that in machine textile fiber material is transmitted, for example transmits with lap or fibroreticulate form.

The device that is used for cleaning this roller 1 comprises a stripping cutter that has a knife plate 2 and a stripping support 3, knife plate 2 is rack-mount, also have a cotton suction duct in addition, cotton suction duct has an intermediary element 4 and two

pipe insert seats

5 and 6, and they are connected with two ends of intermediary element 4.Knife plate 2 is parallel to the axis of roller 1, and its free end leans on mutually with the outer peripheral face of

roller.Suction pipe

4,5,6 axis that also are parallel to roller 1 extend, and comprise a cannelure 4.1 in the intermediary element 4, and it is relative with roller 1.

Suction pipe

4,5, an end of 6 is sealed with a stopper 7.When operation, a suction pipe (not shown) and its other end, promptly the free end of pipe insert seat 5 is connected.

Two

clamping devices

8 and 9 are placed on two bases, and respectively by set

screw

10 and 11 clampings (Fig. 2).Stripping support 3 comprises the protruding dish 12 and 13 (Fig. 3) that is positioned at its end, and protruding dish is separately fixed in the hole of clamping device 8 and 9.Only expressed the hole 14 in the clamping device 8 among Fig. 3, clamping device 9 equally also comprises a corresponding hole.Adopt this mode just stripping cutter 2,3 can be fixed on

suction pipe

4,5, in 6, the same with hole 14, the hole in the supporting

arrangement

8 and 9 has also constituted pivot suspension to stripping cutter 2,3.

Stripping cutter 2,3 has elastic load with respect to

clamping device

8 and 9 on the pivot direction, thereby the free end of knife plate 2 can be pressed against on the outer peripheral face of roller 1.In one embodiment, elastic load produces by reversing disc spring 15, and this spring is installed in the extension inner end in the eyelet 14 of clamping device 8 and 9.Each reverses disc spring 15 all has an end to be inserted in the hole of stripping support 3.Its other end then is placed in the groove of respective clamp device 8 and 9.If a plurality of this grooves are set in

clamping device

8 and 9, be used for receiving the outer end of respective springs, just then the outer end of spring can be pushed in any other the groove, thereby change the elastic load value that spring 15 is provided.On the contrary, also can a plurality of eyelets be set in stripping support 3 for this purpose, be used for receiving the inner of spring 15.

After unclamping set screw 10 and 11 (Fig. 2),

suction pipe

4,5,6 just can rotate in clamping device 8 and 9.Adopt this mode, just can make

suction pipe

4,5,6 with stripping cutter 2 and 3 can do rotary adjusting around the axis of suction pipe.By making

suction pipe

4,5,6 rotations with respect to

clamping device

8 and 9 just can make the effective width of bothrium change, even the distance between the edge of slit 4.1 changes in the free end of knife plate 2 and the

suction pipe

4,5,6.

Suction pipe

4,5,6 also have guide element, and it can move along the vertical guiding device on the machine.In this embodiment, grooving under being shaped as of this guide element (Fig. 1), it is positioned at

clamping device

8 and 9, and is installed in the inside of a guide rail 17, and guide rail is installed in the machine and is parallel with roller 1.This guide rail 17 is connected on the guiding

clamping device

18 and 19, they is fixed on the support of machine by means of the screw (not shown) again.Screw is screwed in guiding

clamping device

18 and 19 the oblong hole 20, like this, after unclamping screw, guide rail 17 just relatively roller 1 make lateral adjustments, thereby the distance between

change suction pipe

4,5,6 and the roller 1.At this simultaneously, the elastic load value of stripping cutter 2,3 has also produced variation, because it and

suction pipe

4,5,6 are regulated together.

By

clamping device

8 and 9 is moved along guide rail 17, clamping device can with stripping cutter 2,3 and

suction pipe

4,5,6 together as a whole the unit be pushed and leave machine, and, again it is pushed back in the machine in cleaning and/or after repairing.

Under the state that inserts, this unit is fixed in the machine by means of being connected, and this connects by

suction pipe

4,5, and 6 entrained elements and an element that links to each other with machine provide.In this embodiment, being connected is produced by a pin of taking the lead 21 (Fig. 3), and this pin is connected the outside of clamping device 9.A perforate interlock mutually in the head of pin 21 and the supporting element 22, described anchor clamps also are used as the displacement position-limiting device of clamping device 9 and

suction pipe

4,5,6 and stripping cutter 2,3 simultaneously.This supporting element 22 is to be installed in the machine with respect to roller 1 horizontal adjustable mode, and its method is similar with guiding

clamping device

18 and 19.
