Pre-drying heating device for rotary screen printing machine

Abstract

The invention discloses a pre-drying heating device for a rotary screen printing machine. The pre-drying heating device comprises a rack, and both ends of the rack are open; two sets of heating platesdistributed side by side in the length direction of the rack are arranged in the rack, and each set of heating plates comprises a bottom heating plate and a top heating plate which are distributed inparallel in the vertical direction; lifting cylinders are arranged on the two outer sides of the rack, a pair of symmetric lifting frames are arranged on the two sides of each lifting cylinder, the bottom ends of the lifting frames are connected with the bottom heating plates through bottom lifting shafts, a lifting rod connected with a piston rod of the corresponding lifting cylinder is arrangedbetween the top ends of every two lifting frames, and the two ends of each lifting rod are connected with the top heating plates through top lifting shafts respectively; long holes for the bottom lifting shafts and the top lifting shafts to move in the vertical direction are formed in the side walls of the rack respectively. The pre-drying heating device has the advantages of being high in dryingefficiency and production efficiency, good in printing effect and capable of improving the product quality.

Description

technical field [0001] The invention relates to a pre-baking and heating device, in particular to a pre-baking and heating device for a rotary screen printing machine. Background technique [0002] Due to the advantages of high production efficiency, wide range of printing products, and relatively stable quality level, rotary screen printing machines have become the main printing production equipment and printing methods in the printing production industry. The existing rotary screen printing machine is not equipped with a pre-baking heating device, and its drying efficiency is poor, the printing speed is slow, and the production efficiency is low; for the special printing requirements such as the reverse side transparent bottom of thin fabrics, anti-batik printing, foaming effect of foam printing, etc. The drying speed is slow, the pattern is easy to open, and the fine effect is affected; if it is not dried in time, it is easy to cause defects such as dragging and staining ...

AI Technical Summary

Problems solved by technology

The existing rotary screen printing machine is not equipped with a pre-drying heating device, its drying efficiency is poor, printing speed is slow, and production efficiency is low; for special printing requirements such as thin fabric reverse bottom, anti-batik printing, and foaming effect of foaming printing, etc. less than; the drying speed is slow, the pattern is easy to melt, which affects the fine effect; if it cannot be dried in time, it is easy to cause defects such as cloth surface dragging and cloth surface staining; therefore, the existing rotary screen printing machine has poor drying efficiency, Problems of low production efficiency, poor printing effect and reduced product quality
