Abstract

The invention provides a double-row chain transmission elliptical track printing device. The double-row chain transmission elliptical track printing device comprises a transmission track, at least onedesk board driving device and a plurality of desk boards of the same structure. Every two adjacent desk boards are connected through a connecting rod. Each desk board driving device comprises an upper left chain wheel, an upper right chain wheel and an upper chain, wherein the upper left chain wheel and the upper right chain wheel are both smooth toothless chain wheels; the left and right ends ofthe upper chain are wound around the peripheries of the upper left chain wheel and the upper right chain wheel correspondingly. The upper chain is of an annular structure and comprises a plurality ofupper chain axle sets of the same structure; upper set gaps are formed between the adjacent upper chain axle sets; each upper chain axle comprises two parallel upper chain axles; an upper axle gap isformed between the upper chain axles of the same set. Plate racks arranged on the desk boards are inserted into the upper set gaps and the upper axle gaps in a matched mode. According to the double-row chain transmission elliptical track printing device, the transmission accuracy of the desk boards is good, the desk boards can form resulting force with the connecting rods and is not likely to shake. The linkage effect of the connecting rods can be given full play to.

Description

technical field [0001] The invention relates to a screen printing device, which belongs to the field of textile machinery, in particular to a double-row chain-driven elliptical track printing device and its use method, which is particularly suitable for improving the accuracy of platen transmission, and can be formed with connecting rods. work together. Background technique [0002] At present, the screen printing process is relatively complicated and there are many stations. In order to improve work efficiency, the transmission track in the screen printing process is generally set as an elliptical track or a circular track. Among them, the circular track is easy to drive, but the stations are fixed. , cannot be added at will, and the elliptical orbit drive is more complicated, but the stations are flexible, and stations can be added in the straight section as needed. The transmission of the existing elliptical track mostly adopts the chain transmission method, and each pri...
