Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of another embodiment of the present invention.

In the figure, the cutting knife 1, the cutting knife 2, the rotary cutter 3, the transmission motor 4, the speed reducer 5, the bearing seat 6, the transmission rotating shaft 7, the cam 8, the lead screw 9 and the sliding seat.

Detailed Description

Example one

Referring to fig. 1, the automatic cutter height adjusting device of the rotary cutting machine comprises a cutter 1 fixed on a feeding mechanism of the rotary cutting machine 2, cams 7 are arranged below two ends of the cutter 1, the cams 7 are in contact with the bottom edges of the cutter 1 in a mutually fit manner, the cams 7 are fixedly connected with one end of a transmission rotating shaft 6, the other end of the transmission rotating shaft 6 is in transmission connection with the output end of a speed reducer 4, the input end of the speed reducer 4 is in transmission connection with a main shaft of a transmission motor 3, and the transmission rotating shaft 6 is fixed on the rotary cutting machine 2 through a bearing seat 5.

The cutter height adjusting device can achieve the purpose of adjusting the cutter height without manual operation, can quickly and accurately adjust the height of the cutter, and improves the working efficiency. When the height of the cutter is adjusted, the positioning part for fixing the cutter is loosened. The cam and the transmission rotating shaft are in mutual eccentric transmission, and under the transmission of the transmission rotating shaft, the cam can push the cutter to perform lifting motion with a certain amplitude, so that the height of the cutter is adjusted.

Example two

Referring to fig. 2, the automatic cutter height adjusting device of the rotary cutting machine comprises a cutter 1 fixed on a feeding mechanism of the rotary cutting machine 2, sliding seats 9 are arranged below two ends of the cutter 1, the sliding seats 9 are in threaded connection with one ends of lead screws 8, the other ends of the lead screws 8 are in transmission connection with a transmission rotating shaft 6, the other ends of the transmission rotating shafts 6 are in transmission connection with an output end of a speed reducer 4, an input end of the speed reducer 4 is in transmission connection with a main shaft of a transmission motor 3, and the transmission rotating shafts 6 are fixed on the rotary cutting machine 2 through bearing seats 5.

The cutter height adjusting device can achieve the purpose of adjusting the cutter height without manual operation, can quickly and accurately adjust the height of the cutter, and improves the working efficiency. When the height of the cutter is adjusted, the positioning part for fixing the cutter is loosened. The lead screw is connected with transmission pivot looks transmission, and the rotation of lead screw can drive the slide and carry out elevating movement, and slide and cutter mutual fixed connection, and then drive the cutter and carry out elevating movement height-adjusting, and the regulation precision can reach 0.1 mm.

The invention can realize the purpose of adjusting the height of the cutter without manual operation, can automatically, quickly and accurately carry out numerical control adjustment on the height of the cutter, and improves the working efficiency qualitatively.
