Embodiment Construction

[0026] Refer to the following Figure 1-14 Embodiments of the present invention will be described.

[0027] figure 1 It is a plan view showing the printing and dyeing unit of the automatic screen printing machine. The automatic screen printing and dyeing machine is equipped with a printing and dyeing unit 2 on an endless belt 1 . exist figure 1 Although only one printing and dyeing unit 2 is shown in the figure, in practice, a plurality of printing and dyeing units 2 may be arranged along the longitudinal direction of the endless belt. The printing and dyeing unit 2 includes guide frames 4 , 4 arranged on the machine table 3 and scraper supports 5 , 5 freely movable supported by the guide frames 4 , 4 . Furthermore, a fixing member 7 for supporting the screen tension frame 6 is attached to the guide frames 4 , 4 .

[0028] The scraper brackets 5, 5 are connected to the timing belts 4a, 4a arranged in the guide frames 4, 4. Timing belts 4a, 4a are wound around timing pull...

Abstract

The invention discloses a scraper pressure regulating device for regulating scraper pressure in an automatic screen printing and dyeing machine. The device comprises a cylinder driving the scraper to ascend or descend, an air pressure loop which switches the air pressure supplied to the cylinder to printing and dyeing pressure or pressure for pressurization origin determination which is lower than the printing and dyeing pressure; a movable limit block which is driven to rise or fall by a number controllable control motor in a height position controllable manner and stops the scraper from descending; a first detection device which detects the position of the movable scraper when the scraper is stopped from descending; an input device for externally inputting an expected height direction variable of the movable limit block; and a control device which controls the control motor according to the input from the input device by taking the position of the movable limit block which is detected by the first detection device when the air pressure loop switches the printing and dyeing pressure into the pressure for the pressurization origin determination.

Description

technical field [0001] The present invention relates to a squeegee pressure adjusting device in an automatic screen printing machine, and more particularly, to a squeegee pressure adjusting device capable of adjusting the pressure when the squeegee pressurizes the screen with good accuracy and good reproducibility. Background technique [0002] In automatic screen printing machines, the squeegee is held on a squeegee support that scans within a guide frame. The squeegee travels in a direction at right angles to the conveying direction of the cloth to be printed and dyed to perform printing and dyeing. The squeegee presses the endless belt with a specified pressure through the screen, and prints and dyes in this state. [0003] In the past, in order to adjust the pressure of the squeegee, the automatic screen printing machine had a screw to adjust the height position of the squeegee. The screw is operated manually. Therefore, the initial blade pressure should be adjusted e...
