Above-mentioned casing 100 is the open square structure in top, installs on the ground of the operation district that the groove was beaten to roll 900, can block the spark that produces when beating the groove to roll 900 for moving roll 900 can not expose completely outside, prevents that the spark from splashing on the operating personnel when the operation from going on one's body, has promoted holistic security performance. The four side walls of the housing 100 may be made of iron plates and mounted by means including, but not limited to, welding or integral molding. In consideration of the firmness of installation, the present invention provides an integral structure between two adjacent sidewalls of the housing 100.

The first rotating shaft 200 is rotatably installed on the inner walls of the housing 100 at opposite sides thereof. The second rotating shaft 300 is rotatably installed at the side of the first rotating shaft 200, and the distance between the second rotating shaft and the first rotating shaft is greater than the diameter of the roller 900 to be grooved. Specifically, in an embodiment of the present invention, two first bearings 201 are installed on the side walls of the two opposite sides of the casing 100, two second bearings 301 are installed on the side of the two first bearings 201, the two ends of the first rotating shaft 200 respectively extend into the inner rings of the two first bearings 201, and the two ends of the second rotating shaft 300 respectively extend into the inner rings of the two second bearings 301. So that the first rotating shaft 200 and the second rotating shaft 300 can rotate relative to the first bearing 201 and the second bearing 301 respectively under the action of the rotating driving device 400, thereby driving the roller 900 thereon to rotate.

The rotation driving device 400 is mounted on the housing 100, and the rotation driving ends of the rotation driving device 400 respectively drive the sprockets (not shown) of the first rotating shaft 200 and the second rotating shaft 300 to rotate through the chains 401, so as to drive the first rotating shaft 200 and the second rotating shaft 300 to rotate synchronously. After the rotation driving device 400 is started, the first rotating shaft 200 and the second rotating shaft 300 are driven to rotate synchronously, so that the roller 900 placed on the first rotating shaft 200 and the second rotating shaft 300 rotates. The rotation driving device 400 may be any device capable of driving the first rotating shaft 200 and the second rotating shaft 300 to rotate, such as a servo motor and a stepping motor.
