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. 1-4, a scraper for a printing machine plate roller comprises a plate roller 1 and a knife rest 2, wherein the knife rest 2 comprises a bottom plate 3 and a scraper clamp 4, the scraper clamp 4 is cylindrical, and the surface of the scraper clamp 4 is provided with a mounting groove 5, the inside of the mounting groove 5 is provided with a blade 6, and both sides of the blade 6 are provided with first threaded holes 7, both sides of the mounting groove 5 and the side surfaces of the scraper clamp 4 are fixedly connected with fixed blocks 8, the middle part of each fixed block 8 is provided with a second threaded hole 9 matched with the first threaded hole 7, the blade 6 is fixedly connected with the fixed block 8 through a first bolt 11, a long shaft 10 penetrates through the middle part of the scraper clamp 4, the number of the mounting grooves 5 is four, and the blades are uniformly and symmetrically distributed on the surface of the scraper clamp 4, the four mounting grooves 5 are provided with the blades, and when one blade 6 is damaged, three spare blades 6 are arranged to prolong the blade replacement period.
Further, the equal fixedly connected with rectangle post 12 in both sides of bottom plate 3 to the top of rectangle post 12 is connected with splint 15 through second bolt 14, and semicircle type recess 13 has all been seted up in the middle part at rectangle post 12 top and the middle part of splint 15 bottom.
Further, a circular clamping hole is formed between the rectangular column 12 and the clamping plate 15, and the circular clamping hole is matched with the long shaft 10, so that the scraper clamp 4 is fixed more firmly and cannot fall off in the using process.
Further, the right side of the long shaft 10 penetrates through and extends to the right side of the rectangular column 12, and the adjusting cap 16 is fixedly connected to the right side of the long shaft 10 and used for switching the standby blade, so that the blade replacing process is simpler and quicker.
Further, a rotating shaft 17 penetrates through the middle of the plate roller 1, the rotating direction of the plate roller 1 rotates anticlockwise, the cutting edge of the blade faces upwards when the blade 6 is in contact with the plate roller 1, and the blade 6 scrapes more uniformly as the blade edge of the blade 6 is the same as the rotating direction of the plate roller 1.
The working principle is as follows: when in use, the blade 6 is firstly adjusted to the corresponding position, when the printing machine starts to work, the printing roller 1 starts to rotate anticlockwise, and the blade 6 side close to the plate roller 1 cleans the redundant printing ink on the plate roller 1 along with the rotation of the plate roller 1, since the blade edge of the blade 6 is in the same direction as the rotation of the plate roll 1 so that the blade 6 scrapes more uniformly, when the blade 6 needs to be replaced, the long shaft 10 is driven to rotate by rotating the adjusting cap 16 anticlockwise, so that the scraper clamp 4 is driven to rotate, the spare blade 6 is rotated to the working position, because the equipment has three more spare blades 6 compared with the prior art, the replacement of the blades 6 is simpler and the replacement period is prolonged, when all the spare blades are used up, it is only necessary to turn the first 11 and second 14 bolts to remove the doctor blade holder 4 and blade and then replace the blade 6, which is the entire operation of the apparatus.
