Tray fixed conveying device for collective doffing of spinning frame

Abstract

The invention relates to a tray fixing and conveying device used for integrated doffing of a spinning machine. A conveying guide rail comprises a double-guide rail structure which is provided with a convex arc-shaped limit surface at the inner side and an arc-shaped supporting surface at the top, a tray structure comprises more than two tray supports, trays and tray pressing plates, a sliding seat of each tray support is arranged on double guide rails, the inner concave cambered surface of each sliding seat is matched with and limited by the convex arc-shaped limit surface on the double guide rails, the arc-shaped supporting surface of the double guide rails supports the sliding seats of the tray supports, at least one pollution discharge channel is formed on the inner concave cambered surface of each sliding seat, the trays are accordingly placed on respective tray supports, a first locating column and a second locating column on each tray support and a first locating column on an adjacent tray support are limited in the horizontal direction, each tray pressing plate is arranged on a respective corresponding tray support by virtue of a connecting piece, and a depositing stand pipe is arranged on each tray pressing plate. The tray fixing and conveying device provided by the invention is reasonable in structure, better fixation property of the trays can be guaranteed, abrasion is small, and operation is stable and reliable.

Description

technical field [0001] The invention relates to a tray fixing and conveying device for collective doffing of spinning frames, which belongs to the field of spinning frames. Background technique [0002] The spinning frame is an important equipment with a large area and a wide range of production processes in the textile industry. Its performance directly affects various aspects such as yarn quality and economic benefits. With the expansion of the textile industry's production capacity and the increasing shortage of industrial labor, spinning frames equipped with highly automated collective doffing devices will surely become the mainstream of the market. [0003] There is a bobbin circulating conveying device for the doffing spinning frame, and one of the bobbin circulating conveying devices is a push-pull rod tray type structure, and the other is a steel belt tray type structure. The collective doffing part of the spinning frame adopts the steel belt tray type to realize th...

AI Technical Summary

Problems solved by technology

[0004] At present, the more advanced collective doffing bobbin conveying device is mainly composed of conveying guide rails, trays, driving rods, steel belts and driving mechanisms. Corresponding to a tray, the steel belt is connected to each lever, and the lever has a vertical lever finger connected to the tray. Driven by the driving mechanism, when the steel belt moves along the guide groove of the conveying guide rail, the tray is moved by the lever. Sliding to or away from the doffing standby position along the conveying guide rail to convey a large number of empty or full yarn bobbins, and conveying along the conveying guide rail, the requirements for the angle of the base installed with it are very high, resulting in very demanding machining accuracy of the base. Difficult to process, inconvenient to install and debug

In addition, the entire tray slides on its outer surface through the lever, which has a large friction area, large resistance, and large wear. In addition, the tray is directly installed on the guide rail and moves along the guide rail. There are trays in the process of fixed transportation or collective doffing. It will rotate freely around its own axis, which will easily cause doffing failure, and when the guide rail is blocked by flying flowers and agglomerates, the tray is easy to detach from the guide rail due to poor self-cleaning ability
