Improved cleaning doctor locking sleeve structure of rotary screen printing machine

Abstract

The invention discloses an improved cleaning doctor locking sleeve structure of a rotary screen printing machine. The locking sleeve structure comprises a locking sleeve side wall, a locking sleeve head blank holder, an open groove and a blank holder groove opening, and further comprises a cylindrical cleaning doctor positioning sleeve which is mounted on a cleaning doctor of the rotary screen printing machine in a sleeving manner, wherein the cleaning doctor positioning sleeve is a hollow body; the interior of the hollow body takes the shape of a stepped structure; the cleaning doctor corresponding to the hollow body is also of the stepped structure; the locking sleeve side wall which is made of a thin metal plate through chipless forming; the locking sleeve head blank holder is designed at one end of the locking sleeve side wall; the open groove is designed on the side near the locking sleeve side wall and the locking sleeve head blank holder; and the blank holder groove opening is also formed in the locking sleeve head blank holder. By virtue of a reinforcing part which is separately machined with the cleaning doctor positioning sleeve, namely the hollow body, the locking sleeve structure is reinforced. The reinforcing part is a thin slat which is partially leant on the locking sleeve side wall.

Description

Technical field: [0001] The technical field of textile machinery of the present invention, in particular, relates to an improved paddle knife locking sleeve structure of a rotary screen printing machine. Background technique: [0002] The rotary screen printing machine used in textile mills is a screen printing machine that uses a continuously rotating seamless cylindrical screen for printing.
