[0024] Specifically, the swinging assembly comprises a rotating shaft 81, an impeller 82, a rotating plate 83, a moving block 84, a return spring 85, a rotating drum 86, a disturbance plate 87, an arc-shaped sliding groove 88, an L-shaped extrusion rod 89, an inclined block 810 and a fixed rod 811. The rotating shaft 81 is rotatably installed on the inner wall of the roller head 3. The outer wall of the rotating shaft 81 is fixed with the impeller 82. The rotating plate 83 is fixed on the outer wall of the rotating shaft 81. The inner wall of the rotating plate 83 is rotatably installed with the rotating drum 86. The rotating drum 86 penetrates through the bottom of the rotating plate 83 and is rotatably connected at the penetration. The outer wall of the rotating drum 86 is fixed with the disturbance plate 87. The outer wall of the rotating shaft 81 is slidably installed with the moving block 84. The bottom of the moving block 84 is fixed with the return spring 85. The bottom of the return spring 85 is fixed on the inner side of the rotating shaft 81. The outer wall of the rotating drum 86 is provided with the arc-shaped sliding groove 88. The top of the moving block 84 is fixed with the L-shaped extrusion rod 89. The L-shaped extrusion rod 89 penetrates through the arc-shaped sliding groove 88 and is attached at the penetration. The bottom of the moving block 84 is fixed with the inclined block 810. The inner wall of the roller head 3 is fixed with the fixed rod 811. The impeller 82 is impacted by the cooling water, so that the impeller 82 drives the rotating shaft 81 to rotate, thereby enabling the rotating plate 83 to agitate the cooling water in the roller head 3, and accelerating the flowability of the cooling water in the roller head 3.

[0025] The disturbance plate 87 swings, so that the cooling water with lower temperature in the middle position of the roller head 3 can be disturbed to the inner wall of the roller head 3, thereby enabling effective cooling operation of the roller head 3 and improving the service life of the roller head 3.

[0026] Specifically, the scraping assembly comprises a connecting rod 91, a scraper 92, a stop block 93 and a connecting spring 94. The connecting rod 91 penetrates through the side wall of the rotating plate 83 and is slidably connected at the penetration. The end point of the connecting rod 91 is fixed with the scraper 92. The outer wall of the scraper 92 is attached to the inner wall of the roller head 3. The end of the connecting rod 91 away from the scraper 92 is fixed with the stop block 93.

[0027] Working principle: when the roller head 3 needs to be cooled, the pump body 6 is started to suck the cooling water, which flows into the roller head 3 through the connecting pipe 7, so as to cool the roller head 3, and when the cooling water is discharged from the connecting pipe 7, the cooling water impacts the impeller 82 to rotate, thereby driving the rotating shaft 81 to rotate, and the rotating plate 83 is driven to rotate, so as to stir the cooling water in the roller head 3, and when the rotating shaft 81 rotates, the moving block 84 and the inclined block 810 are driven to rotate, when the moving block 84 rotates to the top of the fixed rod 811 and the inclined surface of the inclined block 810, the inclined block 810 is pressed upward, the moving block 84 is driven to move upward, the reset spring 85 is stretched, so as to drive the L-shaped pressing rod 89 to move upward in the arc-shaped sliding groove 88, the L-shaped pressing rod 89 presses the rotating cylinder 86 to rotate, so as to drive the disturbing plate 87 to swing, and when the inclined block 810 rotates to not contact the fixed rod 811, the moving block 84 is driven to move downward to reset, so as to drive the L-shaped pressing rod 89 to move downward in the arc-shaped sliding groove 88 to reset, so as to make the disturbing plate 87 swing back, so that when the rotating plate 83 rotates, the disturbing plate 87 swings back and forth, so as to disturb the cooling liquid with low temperature in the middle position of the roller head 3 to the inner wall of the roller head 3, so as to effectively cool the roller head 3.

[0028] When the rotating plate 83 rotates, the rotating plate 83 drives the connecting rod 91 to rotate, and the scraper 92 rotates along the inner wall of the roller head 3, so as to clean the scale attached to the inner wall of the roller head 3.
