Abstract

The invention relates to textile machinery, in particular to an 8-shaped track device of screen printing. The device comprises inner and outer double tracks for supporting printing tables, wherein two adjacent printing tables are hinged through a connecting rod; bearings are arranged between the printing tables and the inner and outer tracks; the inner and outer tracks consist of straight section tracks, transition circular arc tracks and circular arc tracks; the radius of the circular arc tracks is greater than the radius of the inscribed circles of the straight section tracks; the radius of the transition inner track is greater than the radius of the transition outer track; when the printing tables pass through the transition circular arc tracks from a straight line, the space of the bearings matched with the inner track and the outer track is kept unchanged. By using the 8-shaped track, the radius of the transition inner track is greater than the radius of the transition outer track, and the space between the bearing and the track on the lower side of the printing tables is substantially unchanged, so the printing tables do not shake and the printing precision is guaranteed. The impact during transition is reduced, so the noise is reduced. The entire transmission structure is simple and practical, and the cost is low.

Description

Screen printing 8-shaped rail set

Technical field

The present invention relates to field of textile machinery, particularly relate to a kind of 8-shaped track for screen printing station.

Background technology

Screen printing operation is comparatively complicated, so station is more, in order to increase work efficiency, generally elliptic orbit or circuit orbit is arranged in screen printing, and circuit orbit drives simple, but station is fixed, and can not arbitrarily add.Elliptic orbit drives comparatively complicated, but station is flexible, can add station as required at straightway.At present, elliptic orbit is set to the combination that straightway adds head end inscribe semi arch usually, as Fig. 1, when this orbital fashion forwards circular arc turn fractions to from straight line portion, below printing table, between bearing and interior outside track, spacing increases, and makes to bring during printing table transition impact, occurs rocking, affect stamp precision, and noise increases.

Summary of the invention

For the problems referred to above, the object of the present invention is to provide a kind of steady, transmission screen printing 8-shaped accurately rail set of turning.

For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of screen printing 8-shaped rail set, include the inside and outside two-orbit of supporting printing table, rod hinge connection is passed through between adjacent two printing tables, printing table and inner orbit, bearing is equipped with between outside track, its difference is: described interior outside track is by straightway track, transition arc track and arc orbit composition, the radius of arc orbit is greater than straightway track inscribe radius of a circle, the radius of transition inner orbit is greater than transition outside track radius, printing table from straight line through transition arc track, the distance between bearings coordinated with inner orbit and outside track remains unchanged.

The present invention adopts 8-shaped track, and the radius of transition inner orbit is greater than transition outside track radius, and when turning from straight line to transition circle, below printing table, between bearing and track, spacing is substantially constant, therefore printing table there will not be and rocks, and has ensured stamp precision.Decrease impact during transition, therefore noise reduces.Whole drive mechanism is simple and practical, with low cost.

Detailed description of the invention

For understanding the present invention better, illustrating below in conjunction with accompanying drawing and with detailed description of the invention, technical scheme of the present invention to be described further, seeing Fig. 1 and Fig. 2:

By screen printing 8-shaped rail set of the invention process, supporting printing table 3 also arranges fixing stamp station, track is set to inside and outside two-orbit mode, for realizing the interlock of multiple printing table, hinged by rigid link 1 between adjacent two printing tables, connecting rod 1 is connected with platen by pin.Bearing 10 is equipped with between outside printing table 1 and inner orbit, outside track, described interior outside track is made up of straightway track 9, transition arc track 2 and arc orbit 4, the radius of arc orbit 4 is greater than straightway track 9 inscribe radius of a circle, the radius of transition inner orbit 7 is greater than transition outside track 8 radius, printing table 1 from straight line through transition arc track 2, below printing table 1, between bearing 10 and track, spacing remains unchanged.

Above disclosedly be only preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalence change that the present patent application the scope of the claims is done, still belong to protection scope of the present invention.

Claims

1. a screen printing 8-shaped rail set, include the inside and outside two-orbit of supporting printing table, rod hinge connection is passed through between adjacent two printing tables, printing table and inner orbit, bearing is equipped with between outside track, it is characterized in that: described interior outside track is by straightway track, transition arc track and arc orbit composition, the radius of arc orbit is greater than straightway track inscribe radius of a circle, the radius of interior transition arc track is greater than outer transition arc orbit radius, printing table from straight line through transition arc track, the distance between bearings coordinated with inner orbit and outside track remains unchanged.
