Abstract
Description
Technical Field
[0001] The utility model relates to the field of splitting machines, in particular to a knife wheel deviation adjustment system with a knife. Background Art
[0002] In tire splitting sampling tests and waste splitting recycling operations, it is necessary to split various rubber materials in the tire. In various slitting machines and splitting machine structures previously applied for by the existing applicant, a knife wheel is wound around a belt knife. The belt knife rotates with the knife wheel to cut the fed rubber material. The belt knife is subjected to forces at various locations within the cutting width, which can easily cause the belt knife to deflect when it is wrapped around the knife wheel, thereby affecting the cutting efficiency and accuracy. Summary of the Invention
[0003] The utility model provides a knife wheel deflection adjustment system which has a simple structure and can effectively adjust the deflection of a roll on the knife wheel caused by a knife slitting operation.
[0004] The technical solution adopted by the utility model is: a knife wheel deviation adjustment system, which is characterized in that: it includes a knife wheel mounting seat, the central rotating axis of the knife wheel is connected to the knife wheel mounting seat from front to back through a self-aligning bearing, a horizontal guide rail seat is arranged on the rear side of the knife wheel mounting seat, a horizontal deviation adjustment seat is arranged in the horizontal guide rail seat for horizontal guide restriction, the central rotating axis of the knife wheel is connected to the horizontal deviation adjustment seat through the self-aligning bearing, the left or right side thread of the horizontal deviation adjustment seat is connected to the inner end of the deviation adjustment screw, the outer end of the deviation adjustment screw is axially positioned and connected to the deviation adjustment fixing plate and is externally connected to the deviation adjustment rotating head, and the deviation adjustment fixing plate is connected to the knife wheel mounting seat.
[0005] A rotary motor is installed on the central rotating shaft of the cutter wheel.
[0006] The horizontal guide rail seat and the horizontal deviation adjustment seat adopt a dovetail guide rail structure or an inverted T-shaped guide rail structure to cooperate with the guide restriction.
[0007] It also includes two position probes, one at the front and one at the rear, which are arranged above the belt knife edge and along the belt knife direction. The two position probes are connected to the controller.
[0008] The controller is connected to the servo motor, and the servo motor is connected to the outer end of the deviation adjustment screw that passes through the deviation adjustment fixing plate or is connected to the deviation adjustment rotating head.
[0009] By adopting the above technical scheme, the beneficial effect of the utility model is as follows: by observing, or detecting the deviation of the belt knife edge relative to the straight winding direction through the front and rear position probes, the manual or servo motor automatically controls the rotation of the deviation adjustment rotating head through the deviation adjustment screw, driving the horizontal deviation adjustment seat to move along the horizontal guide rail seat, and adjusting the axial angle of the central rotation axis of the knife wheel through the self-aligning bearing in the horizontal deviation adjustment seat, thereby adjusting the deflection of the knife wheel of the winding belt knife, and the deflection of the belt knife is corrected by the deflected knife wheel. After correction, the horizontal deviation adjustment seat can be reset by observing or detecting that the belt knife is deflected to the straight direction through the position probe. The system can correct the belt knife in real time to meet the requirements of stable slitting quality and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
