Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the structure of the roller according to the present invention.

The sequence numbers in the figures illustrate: the roller is 1, the cooling hole is 2, the fixing frame is 3, the bearing seat is 4, the transition sleeve is 5, the cylinder body is 6, the water cooling pipe is 7, the fixing flange is 8, the sealing plate is 9, the fixing bolt is 10, and the water outlet is 11.

Detailed Description

As shown in fig. 1-2, a roller cooling device according to the present invention is provided with a cooling hole 2 in the middle of a roller 1, the cooling hole is a blind hole, the front end of the blind hole closes the rear end opening (for convenience of description, the left side of fig. 1 is the front end, and the right side is the rear end), a fixing frame 3 for fixing a cylinder 6 is provided on a bearing seat 4 or a roller way of the roller, and a transition sleeve 5 matched with the cooling hole is provided at the rear end of the roller; the front end of the transition sleeve is connected with the rear end of the roller, and a cavity in the middle of the transition sleeve is matched with the cooling hole, so that cooling water in the cooling hole flows out of the rear end of the transition sleeve; the cooling device also comprises a cylinder 6, a water-cooling pipe 7 is arranged in the cylinder, a fixing flange 8 is arranged at the rear end of the cylinder, the rear end of the water-cooling pipe penetrates through the fixing flange and is positioned at the outer side of the cylinder, and the outer wall of the pipe body of the water-cooling pipe is fixedly connected with the fixing flange; the water cooling pipe is sleeved on the inner side of the transition sleeve, the front end of the water cooling pipe is positioned at the front end of the cooling hole, and a gap is reserved, so that water in the water cooling pipe can flow out; a sealing plate 9 is arranged at the front end of the cylinder body, an opening matched with the transition sleeve is formed in the middle of the sealing plate, and the size of the opening is larger than the outer diameter of the transition sleeve; the part of the sealing plate, which extends outwards and exceeds the cylinder body, is provided with a fixing bolt hole and is matched with the fixing frame through a fixing bolt 10, so that the cylinder body is fixedly connected with the fixing frame; a drain port 11 is provided at the lower part of the cylindrical body.
