Portable manual curved surface screen printing machine and use method

Abstract

The invention discloses a portable manual curved screen printing machine, and belongs to the technical field of printing machines. The portable manual curved screen printing machine comprises a mounting seat, wherein cushion blocks are arranged at four corners of the bottom of the mounting seat; the center of the inner wall of the bottom of the mounting seat is connected with a rotating rod through a bearing; and the bottom of the rotating rod extends to the outer wall of the bottom of the mounting seat and is provided with an adjusting handle. When workpieces to be printed with different sizes are printed, a screen needs to be replaced, an inner threaded sleeve can be rotated according to the size of the screen, the inner threaded sleeve rotate to enable two groups of lead screws on the upper side and the lower side to stretch and retract at the same time, the distance between two groups of clamping plates on the upper side and the lower side is changed, then clamping pieces of the screen slide left and right, the screen is fixed through the clamping pieces of the screen, then a movable rod and a plugboard move left and right according to the size of the screen, and the length ofthe plugboard inserted into a U-shaped clamping block is changed, so that a scraper assembly is attached to the edge of the screen when descending, and the screen is prevented from warping when a plugboard assembly descends

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a portable manual curved surface screen printing machine and a use method thereof. Background technique [0002] The manual printing machine is widely used in the field of printing irregular surface workpieces, such as wine bottles, pure water barrels, hot water bottles and other workpieces with irregular surfaces. The workpieces to be printed need to be fixed before printing, but the existing printing machines have different fixing specifications. It is time-consuming and labor-intensive to replace the fixture when printing workpieces of different sizes, and the screen needs to be replaced accordingly when printing workpieces of different sizes. Therefore, we propose a portable manual curved surface screen printing machine and its usage method. Contents of the invention [0003] The purpose of the present invention is to provide a portable manual curved surface scree...
