Description

[Detailed Description of the Invention] The present invention relates to an automatic hand-printing method for printing various valve bodies, blankets, etc., and an object thereof is to easily, reliably, and efficiently perform even hand-printing without requiring any skill. The aim is to provide an automatic hand-printing method that can be used.

In textile printing, the desired print can be obtained depending on conditions such as the viscosity of the printing paste, the moving speed of the scaler, and the contact pressure of the scaler against the object to be dyed, but the average distribution of the printing paste onto the surface of the object to be dyed is insufficient. , it is difficult to set the scaler movement speed.

For this reason, printing unevenness may occur, resulting in defective products or dyed products with low commercial value.

Furthermore, if the moving speed of the scaler is slowed down in order to improve the average distribution of printing paste, the printing efficiency will decrease.

The present invention has been made with this in mind, and uses the contact pressure of the scaler supported by the moving frame to the object to be dyed to reduce the printing paste supplied onto the object to be dyed by the scaler. During printing, printing paste is supplied so that a stagnant portion of printing paste of a predetermined width is always formed along the tip contact portion of the scaler on the surface of the dyed object in the moving direction of the scaler. The gist of this paper is an automatic hand-printing method.

In the above method, the means for forming the retention portion includes, for example,
In front of the scaler in the moving direction, a supply gutter having a bath edge formed thereon is horizontally supported at a predetermined interval along the scaler, so that the printing paste flowing into the supply gutter from the printing paste tank is fed from the bath edge. It overflows onto the surface of the object to be dyed.

This supply gutter is preferably supported so that the distance from the scaler can be adjusted.

In addition, as another means for forming a stagnation part, a dam plate for the stagnation is provided at both ends in the width direction of the scaler, and the printing paste supplied onto the object to be dyed is blocked by the scaler and the dam plate. There is also a method in which the particles are temporarily retained on the surface of the object to be dyed, which is a U-shaped plane surrounded by .

Furthermore, when the surface of the printing stand on which the dyed material is placed is inclined, the supply gutter is supported in multiple stages along the inclined surface.

In this case, the amount of printing paste that overflows is larger as the upper part of the slope surface increases (and the distance from the scaler is also adjusted to a certain opening angle relative to the width direction of the scaler, taking into account the viscosity of the printing paste, the angle of inclination, and the moving speed of the scaler). Preferably, a multi-stage feed trough is supported so as to be formed.

Although the scaler is supported by the movable frame described above, it goes without saying that the scaler can also be used in a case where the scaler is placed in a fixed position and the object to be dyed is continuously transported by an endless belt.

In addition, the means for supplying the printing paste is not necessarily limited to a means for overflowing from the edge of the bath; it may be possible to use a hopper with a long and narrow supply port opening in the width direction of the object to be dyed, or a method using a large number of holes or In some cases, a supply pipe with a slit is installed horizontally in the width direction of the printing object.

In either case, if the scaler moves, a predetermined width of printing paste is deposited on the dyed object in the transfer direction, or if the scaler is fixed and the dyed object is transferred, a predetermined width of printing paste is deposited on the dyed object before passing under the scaler. It is necessary that the printing paste be supplied so that a reservoir is formed along the tip contact part of the scaler.

As described above, after the printing paste was distributed in a predetermined width onto the surface of the dyed object in the moving direction of the scaler, the printing paste was rubbed by the contact pressure of the scaler, so that the printing paste flowed down onto the surface of the dyed object. After that, there is a time period for distributing the printing paste until it comes into sliding contact with the scaler.

By forming this distribution time, the printing paste is evenly distributed on the surface of the object to be dyed, so that automatic manual printing without printing unevenness is achieved.

In addition, by setting the distribution time, there is no need to proceed with the printing operation at a slow moving speed that matches the dispersion of the printing paste as in the conventional method, so printing efficiency is significantly improved.
