The present invention relates to a kind of compacting devices, it is used in being equipped with in the right drafting system of roller of spinning machine, this compacting devices comprises a supporting arrangement that is used for being fastened on the drafting system, this supporting arrangement comprises a guid arm and a movable condensers element that is installed on this guid arm, this condensers element has a condensers arm and a condensers body, and the right gusset of this condensers body and roller is adaptive and be used for fiber composite.The invention still further relates to a kind of drafting system of spinning machine, this spinning machine comprises according to compacting devices of the present invention.
Background technology
In the spinning of staple fibre, for example natural fabric is especially in the spinning of cotton or animal lint and analog, be necessary to keep drawing-off in the dominant draft zone by distance, that is to say, not the fiber of being guided by specific device the distance of process as far as possible little.Therefore, in many drafting systems, all be provided with skirt-type conveyer belt guiding device.In skirt-type conveyer belt guiding device, fiber can be displaced to a side, thereby causes relatively poor yarn qualities and the plucking that increases.For fear of these defectives, be known that setting condensers known for everyone in the indication zone.
According to the condensers of the preamble of claim 1 is known various structure arranged.Yet these structures have various defectives.Thereby the combination of condensers and its suspension must need to increase drawing-off by distance in the known structure, and feasible advantage to the small part that obtains by the configuration condensers is eliminated once more.
And because particular design, the operating position of known condensers often is unsatisfied.Even the operation meeting of known condensers brings adverse effect by incorrect position, this situation still takes place.
Therefore, in order to ensure the cotton operation of satisfied collection, actual condensers body should move in its operating position.In the top roller that can after a pair of skirt-type conveyer belt, arrange of this condensers body and the gusset between the bottom roll himself is oriented in the optimal location thus, and can adapt to the motion of fibrous material, for example transverse movement, thus the expection of having guaranteed single fiber or rove is concentrated.And the operating position of condensers body also should adapt with the roller diameter of top roller and bottom roll, this roller diameter in the operating time owing to regrinding changes.
Further a series of problems are found to be in the contact area that is present between top roller and the condensers body.Be known that when single fiber passes through roller nip single fiber can come loose from the fiber combination, and keep adhering to the surface of top roller, these fibers are pulled away by the rotation top roller, and when they reentered roller nip, part turned back in the fiber composite again.Thereby, if the condensers body contacts in the part circumference range with top roller, so just stoped fiber in the promotion campaign common, and fiber was blocked sometimes before entering described contact area by the condensers body with top roller.Because the accumulation of fiber can form fibre ball, on the one hand, this fibre ball has adverse influence to the action of condensers body, and on the other hand, this fibre ball comes loose also harmful to yarn product because freely fly upward sometimes from top roller.
Because the many problems that in condensers development, occur, there are a large amount of different designs needn't be surprised for it.Therefore, for example condensers is fastened on by corresponding fixture that to transport on the arm be known to everybody.This fastening inevitable requirement has small tolerance according to the geometrical condition between fastening point and the top roller and fastening point is accurately navigated to transports on the arm.In addition, restraint location must structurally be installed in to transport on the arm or be installed in one and be fastened on the assembly that transports arm.The installation of the restraint location on this drafting system rolls up the expense of manufacture view when having, perhaps make the transformation renovation of existing drafting system cause waste.Especially the fixed configurations in the fixture that is provided with is under rigidity, the immovable situation, this just situation.
Except above-mentioned all aspects, what deserves to be mentioned is compacting devices must be fast, simple and do not have wrong installation, even, also will satisfy this situation especially installing when carrying out by the relatively poor support staff of qualification.
The example of some known compacting devices, for example part is mentioned hereinafter at the compacting devices that uses at present:
