Incoming film arc rail with good swinging flexibility

Abstract

The invention discloses an incoming film arc rail with good swinging flexibility, comprising two semicircular rail plates, two linear rail plates and two symmetric arc rail plates; a straight guide channel is arranged on the inner side of each arc rail plate, and an arc guide channel is arranged on the outer side of each arc rail plate; each of the inner and outer sides of the linear rail plates is provided with a straight guide channel; one end of each linear rail plate is connected with the corresponding arc rail plate through a rotary shaft, and the other end of each linear rail plate is connected with the tail of the corresponding semicircular rail plate; each of the inner and outer sides of the semicircular rail plates is provided with a straight guide channel, a chain wheel is arranged on the head of each of the semicircular rail plates, and each chain wheel is provided with a raised frustum. By providing the arc guide channels, friction coefficient between chains and the guide channels can be decreased, and transition can be more stable; the linear rail plates and the arc rail plates are of swinging structure, so that automatic adjustment can be done according to the position of incoming film that is under unwinding.

Description

technical field [0001] The invention relates to a film-feeding track, in particular to a flexible film-feeding arc track. Background technique [0002] In the field of special film preparation, the preparation of ultra-thin films is generally made by stretching thicker films after being clamped and transported by rails. The rails are generally divided into inner rails and outer rails, and the film clips are transported through the inner rails. Carry out die drawing, and send it back to the starting position through the outer track to feed the film, because the film released by the unwinding device is prone to small position deviations, which will affect the effect of film drawing. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and provide a flexible film-entry arc track. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a flexible film-entry arc ...
