The present invention relates to a printing pin adjusting device of a flexographic printing press, and in particular, the printing roller by rotating the pressure roller to press the printing material against the printing roller in a simple structure regardless of the main power transmission device. It is about a printing pin adjusting device of a flexographic printing press that can be easily adjusted.

At the same time, the pressure roller is rotated by the rotational force of the interlocking gear connected to several main gears, and each of the pressure rollers is rotated by a gear installed on the outside of each pressure roller to continuously print the prints of various colors on the printing material passing between these rollers. In the conventional flexographic printing press, which does not have an adjustment device for adjusting the printing pint, the printing pint between each printing roller is not exactly matched to correct the duplication of chromaticity which is often caused during printing. After the gear connected to the outside of the in-roller, that is, the gear of the in-roller, which meshes with the gear of the pressure roller, is frequently disconnected and the power transmission between both gears is interrupted, the in-roller is rotated back and forth to adjust the printing pin. You have to reassemble the separate gear, which is very As well as reoul, there was a drawback that it takes a lot of time.

In the present invention, it is conceived in view of such a conventional situation, and by adding only a simple structure to the pressure roller, the power is not transmitted to the power transmission device without separating the power transmission device for transmitting power to the pressure roller. By simply rotating the pressure roller without rotating the platen roller to be adjusted by the printing pin, which will be described in more detail based on the accompanying drawings.

According to the driving of the driving motor 1, several main gears 3 connected to the chain 2 are rotatable, and each main gear 3 has a pressure roller 5 through an interlocking gear 4 interlocked thereto. Of the second, third and fourth interlocking gears (8) (9) (10) with the first interlocking gear (7) installed on the other side of the pressure roller (5) while rotating the driven gear (6). Multi-color printing on the printing material 14 passing between each press roller 5 and the platen roller 11 by rotating each of the platen roller 11, the ink control roller 12, and the ink supply roller 13 together. In the flexographic printing machine, the narrow tubular flange 16 is extended to the opposite side of the first interlocking gear 7 of the pressure roller 5, and the internal gear 17 is installed inside the tubular flange 16. Install a rotating sleeve 18, part of which extends to the outside, installs the driven gear 6 on the outer end, and extends the radial flange 19 inside. Three planetary gears 20 engaged with the gear 17 are installed, and the rotation shaft 18 extends the adjustment shaft 21 to engage the planetary gear 20 with the planetary gear 20 at the inner end thereof. The worm gear 23 is installed at the outer end of the adjustment shaft 21 extending to the outside of the rotary sleeve 18 and the worm 25 on which the adjustment handle 24 is installed is interlocked.

The present invention has a driven gear (6) is rotated in accordance with the driving of the motor (1), which rotates the rotary sleeve (18) accordingly the planetary gear 20 around the fixed sun gear (22) Rotation of the internal gear 17 causes the pressure roller 5 to rotate so that the first interlocking gear 7 of the pressure roller 5 is the second to fourth interlocking gears 8, 9 and 10. By interlocking and rotating each of the platen roller 11, the ink control roller 12 and the ink roller 13 is possible to print on the printing material (14). If the focus adjustment is required, when the adjustment handle 24 is rotated in the state where the driving of the motor 1 is stopped, the worm gear 23 rotates as the worm 25 rotates to rotate the adjustment shaft 21. And rotates the sun gear 22 to rotate the internal gear 17 through the planetary gear 20 engaged in the fixed position, thereby rotating the pressure roller 5, and thus the first interlocking gear 7 ) Can be rotated to rotate each roller together. At this time, since the driven gear 6 whose rotation is suppressed is fixed to the rotary sleeve 18, it is not affected by the rotation of the pressure roller 5. Therefore, the printing pint of the printing material 14 may be adjusted by the rotation of the pressure roller 5 and the rotation of the platen roller 11.

As such, the present invention has the advantage that the focus can be easily adjusted without having to remove each roller or gear in a simple configuration.

(correction). The driven gear 6 of each press roller 5 is rotated by the interlocking gear 4 interlocked with the rotation of several main gears 3, and the rotation of the first interlocking gear 7 of these press rollers 5 is rotated. The first interlocking gear (7) in which the second interlocking gear (8) of the platen roller (11) is interlocked to enable multicolor printing on the printing material (14) passing between the rollers (5) and (11). The narrow tubular flange 16 is extended to the pressurizing roller 5 on the opposite side, and the internal gear 17 is installed inside the tubular flange 16, and the rotary sleeve 18 is installed on the tubular flange 16 so that the driven gear ( 6) is installed, and the radial flange 19 is extended therein to install several planetary gears 20 engaged with the internal gear 17, and the adjustment shaft 21 is extended in the rotary sleeve 18. The outer end of the adjusting shaft 21 which extends to the outside of the rotary sleeve 18 is installed with the sun gear 22 engaged with the planetary gear 20 at the inner end. Is a sample print of a flexographic printing press focusing adjustment device hayeoseo occlusal a worm 25 having to chakseol the worm gear (23) In the knob (24).
