It may further include a blade conveying device 240 for approaching or spaced 230 to the engraving roller 132.

By using the blade transfer device 240 as described above, the doctor blade 230 may be contacted or spaced apart from the side of the plate making roller 132 so that an appropriate doctor blade may be used according to the rotation direction.

Meanwhile, the above-described doctoring device 200 is equally applied to the first doctoring device D1 and the second doctoring device D2, and has been given a separate reference numeral for this purpose.

On the other hand, the blade transfer device 240 is connected to the rotary actuator 241 disposed on one side of the groove 211, the control unit (CON) for controlling the rotary actuator 241, and the rotary actuator 241 Meanwhile, a ball screw 243 installed in the groove 211 and a screw nut mounted on the ball screw 243 are moved up and down by rotation of the ball screw 243 and fixed to the housing 220. 244).

That is, when the ball screw 243 is rotated by the rotary actuator 241, the screw nut 244 installed on the ball screw 243 is raised and lowered.

At this time, since the screw nut 244 is fixed to the housing 220, the housing 220 is raised and lowered, thereby raising and lowering the doctor blade 230 mounted on the housing 220.

Meanwhile, a motor may be used as the rotary actuator 241 for rotating the ball screw 243.

As described above, when the doctor blade 230 descends, the doctor blade 230 comes into contact with the engraving roller 132, and when raised, the doctor blade 230 is spaced apart from the engraving roller 132.

That is, in order to operate the first doctoring device D1, the doctor blade of the first doctoring device D1 is lowered and the doctor blade of the second doctoring device D2 is raised to raise the Depending on the direction of progress, the required doctoring device can be selected and used.

On the other hand, it is also possible to further include an end nut 245 which is mounted on the bottom surface of the groove 211 and the ball screw 243 is rotatably mounted.

This is to allow the ball screw 243 is mounted on the end nut 245 to rotate more stable rotation.

On the other hand, it may further include a bracket 242 is disposed on the top surface of the groove 211 is fixed to the rotary actuator 241 can be more firmly fixed to the rotary actuator 241.

In this embodiment, as shown in Figure 4, the support 210 is installed on the left and right sides of the plate making roller 132, respectively, it may be installed to extend in the width direction of the doctor blade 230.

However, the support 210 is intended to support the housing 220 and the doctor blade 230 as described above, as long as the support 210 achieves this purpose, even if the support 210 has a different shape. All belong to the present invention.

On the other hand, the groove 211 of the support 210 is shown to have a rectangular cross section, which is an example that the ball screw 243 is mounted while the housing 220 can be in contact with the lifting and lowering It's just that.

Meanwhile, the bracket 242 may have a rectangular plate shape, but the bracket 242 is intended to fix the rotary actuator 241. The bracket 242 may have a different shape as long as the bracket 242 achieves this purpose. Even if it is natural that all belong to the scope of the present invention.

As described above, the doctor blade 230 can approach or separate the doctor blade 230 from the plate making roller 132 by the blade transfer device 240 of the present invention. It is also possible to facilitate the transfer of the doctor blade 230 more smoothly.

That is, after forming a plurality of grooves 211 in the width direction of the support 210, the blade transfer device 240 mounted on the grooves 211 is also mounted to each of the grooves 211, respectively.

In this case, since the housing 220 is moved up and down by the blade transfer devices 240 installed in the grooves 211, the housing 220 and the doctor blade 230 can be more stably transferred.

On the other hand, the inside of the housing 220 in contact with the groove 211 is in contact with the doctor blade 230 to sense the pressure applied to the doctor blade 230 and the pressure connected to the control unit (CON) It is also possible to further include a sensing means 290.
