Problems solved by technology

The main disadvantage of the known printing press is, inter alia, that the system for moving the frame is very complex and fragile
For this reason, the frequent adjustment operations necessary to compensate for the damage to the parts require particularly long intervention times and downtimes

Embodiment Construction

[0020] figure 1 Plan view representing the kinematic system of the fixed structure 1 and the frame (not shown in the figure for the sake of simplicity) of the screen printing machine for screen printing according to the present invention, the fixed structure is respectively connected to the frame connected to the support plane and connected to the printing The frame of the bridging device (not shown in the figure) is integrated into one piece.

[0021] The kinematic system of the present invention is installed on the fixed structure 1, comprises four pairs of eccentric wheels 10, 20, 30 and 40, and these eccentric wheels will be combined below figure 2 A pair of eccentrics 40 shown in is described in detail.

[0022] The motion of the system is provided by an electric motor 2, which is transmitted from a first motion distribution box 3 to a pair of shafts 4 and 5, which are output from opposite sides of the distribution box 3, respectively. The shaft 5 is connected to a sec...

Abstract

A machine for screen printing on flat paper, comprising a first moving frame connected to the support plane of the paper to be printed, a second moving frame supporting the printed screen and components to guide and move the squeegee Knife. Pairs of eccentric wheels (10, 20, 30, 40) are arranged perpendicular to the direction of the support plane, so as to move the first and second frames cyclically between an open position and a closed position, in which the printed frame is removed. into a blank to be printed, and in the closed position, maintains the to-be-printed sheet on the support plane during the continuation of the printing process. The machine significantly reduces adjustment interventions to maintain synchronization between different moving parts, simplifies maintenance and adjustment interventions in moving parts, and enables low-cost manufacturing.

Description

technical field [0001] The present invention relates to a machine for screen printing on flat surfaces such as paper or similar materials, or on flat surfaces made of other materials, such as printed circuit boards, for example. Background technique [0002] Machines of the known type for screen printing on flat surfaces generally comprise a fixed structure on which a first frame is movably connected, connected to a support plane, in A paper to be printed taken out from the paper feeding station is placed on the support plane. Also connected to the fixed structure is a second frame which supports a printing screen and parts for guiding and moving a printing bridge mounted with a squeegee. [0003] The printing cycle consists of the separation of the support plane from the structure supporting the screen and printing bridge means during the infeed process of a new sheet of paper to be printed, leaving the means for holding the paper on the lower support plane and supporting ...
