The present invention relates to the vertical motion and rotational device of the curved part and flat surface automatic or semi-automatic silk printing machine, the component holding the silk screen plate and the squeezing component reciprocating by hydraulic or pneumatic pressure. By making the silk screen plate and the sage to be reactive according to the shape of the printed material, the irregular part of the printed material is effectively coated with ink, thereby improving the precision and efficiency of the silk screen printing.

Conventionally, in the silk screen printing method by hand, the automatic silk screen printing machine has recently been spreading, and thus, the automation of silk screen printing has been gradually achieved.

However, the automatic silk screen printing machine has the following problems in the silk screen plate and the scale configuration to be treated with the printed object.

Conventional screen plate gripping and skew components are only capable of horizontal movement when they are in contact with the printed material, so there is no problem when the printed object has a smooth shape without irregularities. Due to the irregular surface and the elliptical part such as the curved part and the uneven part rather than the flat surface, only the horizontal movement of the screen plate and the scale as described above does not allow ink to penetrate the curved part and the uneven part, resulting in a poor printing condition. The situation is avoiding the automatic silk screen printing machine.

In detail, the conventional silk screen plate clamping part is fixed to the horizontal frame 22 for horizontally conveying two silk screen plate clamping frames 21 in the feed table 23, as shown in FIG. The clamping frame 21 for clamping the silk screen p repeats only the horizontal movement in accordance with the operation of the horizontal frame 22 in the feeder 23, and only by adjusting the screen plate. Only height and horizontal position of 21) can be adjusted.

In addition, the skating component is also configured to repeat only the vertical movement to move the horizontal movement and the two cages in a fixed state of the cage.

The present invention is to solve the conventional problems as described above, in that purpose, by providing a configuration that enables the vertical movement and rotation of the silk screen plate clamping frame and the vertical movement and rotation of the scale has an irregular surface Even if the printed object is in a good print state.

On the basis of the accompanying drawings will be described in detail the configuration of the present invention.

In the case where the ends are inserted into the transfer table 11 and the vertical frames 2 which form the silk screen plate shanghai screw 14 are adhered to each other, the vertical frames 2 are springs 2d and 2d '. In the lower part of the lower frame 21 connected to the lower frame 21 having the 22, the protrusion 2a having the protrusion 2b and the recess 2c is projected, and the protrusion 2a is silk-screened. A shaft hole 1b in which the expansion hole 1c in the center of the projecting portion 1e of the plate clamping frame 1 was formed was inserted through a washer 1f, and was fitted with a fixing ring 1d.

On the other hand, as shown in FIG. 5, the projection shaft 5a which has the protrusion part 5b and the recessed part 5c similarly to the screen plate clamping frame mentioned above on the inner side of each of the two fixed fixing vices 5 is provided. The protrusion 5a was inserted into the shaft hole 7a having the expansion hole 7a 'formed in the housing connecting member 7 through the washer 7b, and fixed by a fixed granule (not shown). And, it is a structure in which the spring (6) is held in the interior of the housing connection value (7) connected by the cylinder case (8) and the piston (9).

In the figure, reference numeral 10 is a cylinder, 13 is a silk screen plate fixing bolt, 1a is a silk screen plate holding part.

The effect of the present invention of the structure as described above will be described.

First, the operation of the flat and curved automatic silk screen printing machine will be described as follows.

As shown in FIG. 1, the clamping frame 1 sandwiching the silk screen plate p is horizontal because the horizontal frame 3 inserted into the feeder 11 is reciprocated in the feeder 11. The two male cages 4 are moved by the hydraulic or pneumatic piston 9 in the cylinder 1 alternately, and the horizontal movement by a separate hydraulic, pneumatic or other power.

When the printed surface is flat, the silk screen plate p is fixed in contact with the printed surface, and the printed surface is printed while the scale 4 horizontally moves the mesh surface of the silk screen plate. When the surface to be printed is curved, the silk screen plate p has a printing function of horizontally moving in contact with the surface to be printed while being in contact with the mesh surface of the scale silk screen plate p. As shown in FIG. 3, the protrusion 2b of the protrusion 2a is slidable in the shaft hole 1b, and thus the expansion hole 1c of the shaft hole 1b is made larger than the arc of the protrusion shaft 2a. By increasing the arc of, the shaft 2a moves in the shaft hole 1b, but the movement thereof is restricted. It is preferable that the left and right rotations of the shaft 2a do not exceed 10 °. The washer 1f eliminates the rotation inhibiting element of the screen plate clamping frame 1 due to the excessive friction surface by eliminating contact portions between the outer surface of the protrusion 1e and the inner surface of the vertical frame 2 which are mutually abutted.

In addition, the vertical movement of the silk screen sandwiched by the spring (2d) formed in the vertical frame (1) 1 is possible.

On the other hand, the cage fixing vice 5 on which the male cage 4 is mounted is rebounded in a limited manner by revolving in accordance with the shape of the to-be-chained body while serving as a housing connecting body as in the case of the screen plate clamping frame described above. (6) is to move up and down.

As shown in FIGS. 6 and 7 of the accompanying drawings, the silk-screen plate P and the cage 4 filled with ink according to the shape of the printed object T are reacted vertically and rotationally. By contacting the surface of the printed matter (T) in various ways, evenly penetrated, uneven portion and elliptical ink penetrates evenly to increase the precision and efficiency of printing.

As described above, it is a useful design that maximizes the precision and efficiency of silk printing by providing the screen plate and the vertical motion and rotation device of the screen of the present invention which are relatively hard to the automatic silk screen printing machine avoided by the above problems.
