Description
Technical field
The present invention relates to dispose a frame of drafting system, it have a plurality of bottom rolls and a plurality of respectively with the pressure roller of bottom roll configuration, here at least one pressure roller is from a load situation, be that pressure roller adds the position that is pressed against on the corresponding bottom roll, can move to a unloading position, this position pressure roller no longer with the contact of corresponding bottom roll, and have a depression bar at least in a draw zone of drafting system.
Background technology
With regard to many-side, this class drafting system is known to everybody such as the drafting system of combing machine and drawing frame.Fibrous material with fiber web form or one or more sliver form be fed into drafting system and be generally on three bottom roll between carry out drawing-off, general roller is to being made up of a bottom roll and a pressure roller respectively.In order to reach the drawing-off effect, each peripheral speed to roller is to increase by the sliver traffic direction.Being placed in a side also is known to everybody for middle bottom roller and middle pressure roller and the opposing party for exporting depression bar between bottom roll and the output press roll or pressure bar, this two square one-tenth main drawing area.Depression bar is used to guide and swims, i.e. the fiber that is not held between two pairs of rollers.Best mode is, the fiber of main drawing area or by middle roller to grip or by delivery roller to gripping.Because this ideal situation can not realize that it is uncontrolled that most of fibers are engraved in the draw zone motion at this moment.In order to control these fibers to a certain extent, use so-called depression bar.
In order to make fibrous material can feed drafting system when the machine entry into service or after sliver fracture and to regulate and clean, pressure roller is to swing usually, moves to unloading position from load situation or running position.Fibrous material can be spread and put on bottom roll, and then pressure roller is got back to load situation from unloading position.In this operating process, depression bar keeps its origin-location, like this fibrous material below depression bar-be pressurized to the depression bar of fiber-be directed into delivery roller from above right.This process is comparatively to bother.Depression bar cleaning is only just possible during no fibrous material in drafting system.
Summary of the invention
Task of the present invention is, further improves the above-mentioned type frame, simplifies its operability.
This task is such solution in above-mentioned class frame, promptly depression bar when the motion of at least one pressure roller in company with motion.Optimal way is that this technical scheme allows depression bar to move simultaneously at least one pressure roller when load situation is transferred to unloading position, causes depression bar no longer to be positioned at draw zone.Therefore guarantee the good accesibility of the fiber contact zone and the drafting system of depression bar, this is for the cleaning advantageous particularly.
Because bigger free space in the draw zone can carry out the adjusting of drafting system more conveniently.For this reason, can be direct when fibrous material is put into drafting system, promptly do not need by a depression bar guiding, right from middle roller to being input to delivery roller.When depression bar is placed in front draft zone of drafting system-can be used as replacement scheme or in main drawing area, adorn a depression bar-also can obtain these advantages in addition.
The particularly preferred form of implementation of the present invention is that at least one pressure roller of arrangement and a depression bar in a reel cage can make at least one pressure roller turn to unloading position together with depression bar from load situation when this reel cage swing.For this reason, only need a handle just can make the swing of at least one pressure roller and depression bar.
Optimal way is that reel cage comprises two rocking arms on the front that at least one pressure roller and a depression bar are arranged.Two rocking arms are to interconnect by a common axis of rotation.
Be preferably in and settle at least two pressure rollers on the reel cage.In the optimal technical scheme about this respect, they are a feeding pressure roller of a pair of feeding roller and a middle pressure roller of a pair of middle roller.This possibility especially is provided aspect combing machine, only these two pressure rollers are placed in the reel cage, has only very low obvolvent performance because be fed into the yarn of drafting system, thereby be easy to be out of order, so that get involved in yarn when being preferably in the fault that once should eliminate as few as possible, for example break down, do not need delivery roller together to swing in the front draft zone.The substitute is, fixing a breakdown only needs the reel cage with two pressure rollers in band front draft zone upwards to swing.
According to the form of implementation that the front has been talked about, output press roll can be placed in second independent reel cage, so that in the dominant draft zone with especially in the right zone elimination fault of delivery roller, thus can convenient fibrous material feeding drafting system.
Another selectable scheme is, except other two pressure rollers, output press roll also can be bearing on the common reel cage, and this shows that it is a special solution of simplifying of design.
If output press roll is bearing in second independent reel cage, depression bar or a depression bar are placed in second reel cage with having advantage.The advantage of this form of implementation is, when breaking down in the front draft zone, first reel cage with the front draft zone pressure roller need only be swung open, and depression bar can keep contacting with fibrous material, so fiber seldom experiences interference.
Particularly preferably be, it is adjustable that depression bar enters aspect the degree of depth of fibrous material at it.This adjusting is preferably according to needing processing fiber material and special fibre length according to it.If because fibre length needs bigger spigot surface than staple fibre control, then depression bar preferably is pressed into fibrous material deeply.
If depression bar is bearing in the support at least, this side of support-or directly or by one or more intermediary element-be fixed on the reel cage, be particularly conducive to the better modulability of depression bar.In the case, at least one support is preferably mounted on of two end faces.Preferably depression bar also is bearing on another end face of a this support.
The adjusting possibility of depression bar enlarges by at least one support.On the one hand, the best adjustable ground of at least one support is placed in the rocking arm, and therefore by regulating support, depression bar can be at relevant draw zone level and/or perpendicular positioning.On the other hand, depression bar preferably is placed in the support and can regulates automatically, so that at least one support-and as the replacement scheme of regulating at least one support in the reel cage or additional aspects-make accurate localization by regulating the depression bar of depression bar in can the counter extensioin district.Above-mentioned two kinds of adjusting possibilities can realize by rectilinear motion and/or oscillating motion.
In the relevant optimal technical scheme, depression bar can be bearing in the slot of at least one support with regulating, moves by the straight line of regulating depression bar in this way and realizes depression bar desired position in draw zone.
Other optimized technical scheme of the present invention are that these features by dependent claims show.
According to some figure the present invention is elaborated below.
