Furthermore, the two sides of the bottom of the mounting seat are respectively provided with a rotating shaft, the two sides of the top of the connecting seat are respectively connected with a shaft sleeve, and each shaft sleeve is rotatably connected with one rotating shaft.

Further, the lifting assembly is a lifting cylinder, and a telescopic rod of the lifting cylinder is fixedly connected with the mounting block.

Further, the gear is a sector gear.

Further, the rotation angle of the ink scraping cutter ranges from 0 to 180 degrees.

The utility model discloses realize following beneficial effect:

the utility model discloses a set up positive reverse motor and drive the worm wheel positive reverse rotation, make the connecting seat that has the gear realize positive reverse motion to the function that has reached angle modulation of messenger's wiping cutter has guaranteed the wiping speed of wiping cutter.

Drawings

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.

Fig. 1 is a schematic view of the overall structure of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, the special ink scraping device for a printing machine comprises a frame 10, a stepping servo module 20 and an ink scraping mechanism, wherein the stepping servo module is fixedly arranged at the bottom of a cross beam of the frame, the ink scraping mechanism comprises a lifting assembly 110, an ink scraping cutter 30, a mounting seat, a forward and reverse rotation motor 40, a worm 50, a worm wheel 60 and a connecting seat 80, the lifting assembly is slidably connected with the stepping servo module, the lifting assembly moves along the length direction of the bottom of the frame under the driving of the stepping servo module, the lifting assembly is fixedly connected with the mounting seat 100, a mounting groove 70 is formed in the mounting seat, the forward and reverse rotation motor is fixed on the outer wall of one side of the mounting seat, an output shaft of the forward and reverse rotation motor is integrally connected with the worm wheel and used for driving the worm wheel to rotate forward and reverse, the worm is fixedly arranged at the upper part of the mounting groove and is, the gear is connected with the worm wheel meshing, and when the worm wheel was just reversing, the gear was also followed just reversing, and the wiping cutter was fixed in the below of connecting seat, and when the gear was just reversing, connecting seat and wiping cutter were also following just reversing the motion, just so means the adjustment that the angle had been realized to the wiping cutter.

In this embodiment, the bottom two sides of the mounting seat are respectively provided with a rotating shaft 120, the top two sides of the connecting seat are respectively connected with a shaft sleeve 130, each shaft sleeve is rotatably connected with one rotating shaft, and when the forward and reverse rotation motor drives the connecting seat to rotate forward or reverse, the shaft sleeves are matched with the rotating shafts to rotate.

In this embodiment, lifting unit is the lift cylinder, and the telescopic link and the installation piece rigid coupling of lift cylinder, and after the angle had been adjusted to the wiping cutter, the drive of lift cylinder was wiped the ink cutter and is descended, made the wiping cutter can begin to scrape the seal with the contact of half tone (the utility model discloses do not mark).
