Detailed Description

Referring to fig. 1-4, the present invention provides an embodiment:

the utility model provides a gravure printing roller, is connected with pivot 1 through the bearing including being fixed in mount pad 2 on the equipment, 2 middle parts of mount pad, and wherein, mount pad 2 is used for the support of counter shaft 1, and pivot 1 can be fixed with mount pad 2 through the bearing. The middle part of the rotating shaft 1 is provided with a rotating drum 9, the rotating drum 9 and the rotating shaft 1 can be integrally processed, and the outer diameter of the rotating drum 9 is larger than that of the rotating shaft 1. The outer side of the rotary drum 9 is connected with the roller rubber sleeve 3 in a clamping way through a key, and the centers of the rotary shaft 1, the rotary drum 9 and the roller rubber sleeve 3 are collinear. Personally submit the annular in the outside of rotary drum 9 and be equipped with the groove with the key joint, be connected rotary drum 9 and roller gum cover 3 through the mode of key, at the rotatory in-process of pivot 1, can make rotary drum 9 and roller gum cover 3 rotate simultaneously, and can not make rotary drum 9 and roller gum cover 3 produce relative rotation. Meanwhile, the roller rubber sleeve 3 can be conveniently mounted and dismounted by the connecting mode of the roller rubber sleeve 3 and the rotary drum 9 key.

Lower tip is equipped with collection frame 5 before roller gum cover 3, collects frame 5 and is fixed in on pivot 1 through the bearing, and collects frame 5 and be the lower tip before roller gum cover 3 of "U" font joint. Collect frame 5 and locate between adjacent mount pad 2, and be equipped with the interval between collection frame 5 and the mount pad 2. The rear side of the inner cavity of the collecting frame 5 is connected with a supporting rod 10 through a limiting bolt 8, and the lower end face of the collecting frame 5 and the left side face of the mounting seat 2 form an included angle of 30-60 degrees. After the collection frame 5 is separated from the limit of the limit bolt 8, the collection frame can rotate around the center of the rotating shaft 1; after the limiting bolt 8 is inserted into the through hole 12 on the supporting rod 10, the limiting bolt 8 is in threaded connection with the supporting rod 10, and at the moment, the collecting frame 5 and the left side surface of the mounting seat 2 form a certain angle.

The lower end portion of the left side of the collecting frame 5 is communicated with a liquid outlet pipe 7, the inner cavity of the liquid outlet pipe 7 is communicated with the inner cavity of the collecting frame 5, and ink entering the collecting frame 5 can be collected in a centralized mode through the arrangement of the liquid outlet pipe 7. The limiting bolt 8 is inserted into the hanging end of the supporting rod 10 from outside to inside, the limiting bolt 8 is connected with the supporting rod 10 through threads, and the length of the supporting rod 10 is smaller than the effective length of the inner side of the collecting frame 5.
