[0005] Further, the longitudinal section area size of the square shaft is 30%-40% of the longitudinal section area size of the end part roller body.

[0006] Further, the inner end face edges of the end part roller body and the square shaft are all provided with round corner structure.

[0007] Further, the both ends of the roller sleeve are provided with positioning shoulder surface matched with the end part roller body, and the end part roller body can abut on the positioning shoulder surface of the roller sleeve.

[0008] Compared with the prior art, the utility model has the advantages that: the three-section roller body structure of the cold rolling roller has the advantage of convenient disassembly and assembly, the roller sleeve and the middle part roller body are rotatably and slidably assembled and disassembled, the cooperation precision between the roller sleeve and the middle part roller body is improved, that is, there is no gap between the roller sleeve and the middle part roller body, and the finished product plate surface quality after copper foil and copper plate strip finishing can be improved. BRIEF DESCRIPTION OF DRAWINGS

[0009] The utility model will be further explained in connection with the drawings.

[0010] Figure 1 is a sectional view of the utility model. DETAILED DESCRIPTION

[0011] The utility model is described in detail below in combination with specific embodiments:

[0012] As Figure 1 A copper cold rolling roller shown in the figure, including middle roller body 1, flange 2, end roller body 3, square shaft 4, roller shaft 5 and roller sleeve 7, end roller body 3 is fixedly connected with flange 2, the both ends of middle roller body 1 are provided with square groove 11 matched with square shaft 4, roller sleeve 7 is slidably sleeved and installed on middle roller body 1, square shaft 4 is fixedly arranged at the center position of the inner end face of end roller body 3, roller shaft 5 is coaxially slidably installed in end roller body 3 and square shaft 4, the inner end of roller shaft 5 is provided with external thread structure 6, the bottom of square groove 11 is provided with a threaded hole, the inner end external thread structure 6 of roller shaft 5 is screw-connected and installed in the threaded hole of square groove 11, square shaft 4 is gap slidably installed in square groove 11, end roller body 3 is gap slidably installed in roller sleeve 7, and roller sleeve 7 is pressed and fixed by both sides flange 2.

[0013] The longitudinal section area size of square shaft 4 is 35% of the longitudinal section area size of end roller body 3, can guarantee the structural strength of middle roller body 1 after being provided with square groove 11, and the structural strength of square shaft 4 is also higher, can avoid the problem of distortion when square shaft 4 drives middle roller body 1 to rotate.

[0014] The inner end face edges of end roller body 3 and square shaft 4 are all provided with round corner structure, so that end roller body 3 and square shaft 4 can be easily embedded and installed into roller sleeve 7 and square groove 11 respectively.

[0015] The both ends of roller sleeve 7 are provided with positioning shoulder faces matched with end roller body 3, end roller body 3 can abut on the positioning shoulder faces of roller sleeve 7, through the positioning shoulder faces, when middle roller body 1 and roller sleeve 7 are installed, middle roller body 1 can be centrally positioned after installation, and when middle roller body 1 and roller sleeve 7 are installed, the rotary sliding fit mode is adopted to reduce the resistance when installed in a straight line, if middle roller body 1 is not centrally positioned after installation, square shaft 4 needs to push roller sleeve 7 to slide in a straight line relative to middle roller body 1, at this time, the installation resistance is larger.

[0016] The roller body of the utility model is divided into three-section structure of one middle roller body and two end roller bodies, when installed, roller sleeve 7 and middle roller body 1 are slidably installed and matched in the rotary mode, then end roller body 3 and roller sleeve 7 are installed and matched in a straight line, flange 2, end roller body 3 and middle roller body 1 are pressed by roller shaft 5 provided with external thread structure, when disassembled and maintained, roller shaft 5, flange 2 and end roller body 3 are removed, then roller sleeve 7 and middle roller body 1 are separated by rotating and sliding.
