The driving roller and the forming fillet can be adjusted along the roller adjustment groove according to the width of the insulating cardboard ring. The distance between the trimming knives; a pair of supporting rollers are respectively installed on the roller adjustment grooves on both sides of the work surface; The supporting roller and the forming fillet trimming knife are located on the same side of the insulating cardboard ring. When the motor is working, the driving roller drives the insulating cardboard ring to rotate with the assistance of a pair of supporting rollers, thereby realizing automatic feeding and chamfering of the insulating cardboard ring.

During the processing, first place the insulating cardboard ring between the forming fillet trimming knife and the driving roller, and then adjust the distance between the forming fillet trimming knife and the driving roller along the roller adjustment groove in the middle, so that the insulating cardboard The ring is just stuck between the two, fix the driving roller, and then adjust the position of a pair of supporting rollers along the roller adjustment grooves adjusted on both sides, so that the pair of supporting rollers are stuck on the edge of the insulating cardboard ring, and then the pair of supporting rollers Fix it on the roller adjustment groove; then turn on the trimming machine and the motor to make the insulating cardboard ring rotate while chamfering, and complete its automatic chamfering process.

Further, the middle roller adjustment groove is set on the central axis of the worktable along the length direction, the roller adjustment grooves on both sides are symmetrical to the middle roller adjustment groove, and a pair of support rollers are symmetrical to the circle center of the forming fillet trimming knife.

Further, a cylindrical protective cover is provided above the forming fillet trimming knife, the lower end of the protective cover is set on the worktable, and the upper end is connected with a dust suction interface, and is connected to a vacuum cleaner through the dust suction interface.

Beneficial effects: Compared with the prior art, the device for chamfering the edge of the insulating cardboard circle provided by the utility model has the following advantages:

1. The structure is simple, the production is easy and the production cost is very low.

2. Easy and fast clamping, automatic feeding reduces labor intensity, and high work efficiency (insulated cardboard rings with a diameter of about 1 meter can be chamfered and deburred for 1 piece in 1 minute, and the original manual operation takes more than 5 minutes).

3. The connection of the dust collection device improves the production environment and avoids the original phenomenon of paper scraps all over the floor.

4. The rotating cutter is isolated from the operator through the protective cover, which ensures the personal safety of the operator.
