Abstract

A cutter head includes: a support platform; a double curved surface member mounted on the support platform and having a first curved surface and a second curved surface; a cutter wheel support member and a roller wheel support member moveably mounted on the support platform, respectively; a cutter wheel and a roller wheel mounted on the cutter wheel support member and the roller wheel support member, respectively; a first transmission mechanism mounted on the support platform, configured to be mated with the first curved surface, and connected to the cutter wheel support member, so as to transmit a movement of the double curved surface member to the cutter wheel; and a second transmission mechanism mounted on the support platform, configured to be mated with the second curved surface, and connected to the roller wheel support member, so as to transmit a movement of the double curved surface member to the roller wheel. The cutter head has a compact structure, and it improves the levelness of the cutter wheel and the roller wheel, and increases the mechanical precision.

First claim

What is claimed is:

1. A cutter head, comprising:
a support platform;
a double curved surface member mounted on the support platform and having a first curved surface and a second curved surface;
a cutter wheel support member and a roller wheel support member moveably mounted on the support platform, respectively;
a cutter wheel and a roller wheel mounted on the cutter wheel support member and the roller wheel support member, respectively;
a first transmission mechanism mounted on the support platform, configured to be mated with the first curved surface, and connected to the cutter wheel support member, so as to transmit a movement of the double curved surface member to the cutter wheel; and
a second transmission mechanism mounted on the support platform, configured to be mated with the second curved surface, and connected to the roller wheel support member, so as to transmit the movement of the double curved surface member to the roller wheel.

2. The cutter head according to claim 1 , further comprising a protection case mounted on the support platform,
wherein the double curved surface member, the first transmission mechanism and the second transmission mechanism are received in the protection case.

3. The cutter head according to claim 2 ,
wherein the double curved surface member comprises a double curved surface cam, and the first curved surface and the second curved surface are rotationally symmetric with respect to each other.

4. The cutter head according to claim 3 ,
wherein the first transmission mechanism comprises:
a first roller rotatably coupled with the first curved surface of the double curved surface member; and
a first positioning seat movably mounted on the support platform, the first roller being rotatably mounted on the first positioning seat, so as to transmit the movement of the double curved surface member to the cutter wheel as the first curved surface drives the first roller to rotate; and
wherein the second transmission mechanism comprises:
a second roller rotatably coupled with the second curved surface of the double curved surface member; and
a second positioning seat movably mounted on the support platform, the second roller being rotatably mounted on the second positioning seat, so as to transmit the movement of the double curved surface member to the roller wheel as the second curved surface drives the second roller to rotate.

5. The cutter head according to claim 4 ,
wherein the first transmission mechanism further comprises a first transmitting seat provided between the first positioning seat and the support platform and connected to the cutter wheel support member; and
wherein the second transmission mechanism further comprises a second transmitting seat provided between the second positioning seat and the support platform and connected to the roller wheel support member.

6. The cutter head according to claim 5 ,
wherein the first roller is in contact with the first curved surface via higher pair contact, and the second roller is in contact with the second curved surface via higher pair contact.

7. The cutter head according to claim 5 ,
wherein the first transmission mechanism further comprises a first reset spring, the first transmitting seat being configured to be moved against a spring force of the first reset spring under driving of the first positioning seat; and
wherein the second transmission mechanism further comprises a second reset spring, the second transmitting seat being configured to be moved against a spring force of the second reset spring under driving of the second positioning seat.

8. The cutter head according to claim 7 ,
wherein the first reset spring is provided between the first transmitting seat and the protection case, and the second reset spring is provided between the second transmitting seat and the protection case.

9. The cutter head according to claim 5 ,
wherein the first roller is rotatably connected to the first positioning seat by a first rotation shaft, and the second roller is rotatably connected to the second positioning seat by a second rotation shaft.

10. The cutter head according to claim 5 ,
wherein a third reset spring is provided between the cutter wheel support member and the support platform, the cutter wheel support member being configured to be moved against a spring force of the third reset spring under driving of the first transmitting seat; and
wherein a fourth reset spring is provided between the roller wheel support member and the support platform, the roller wheel support member being configured to be moved against a spring force of the fourth reset spring under driving of the second transmitting seat.

11. The cutter head according to claim 5 , further comprising a first rail and a second rail fixed to the support platform,
wherein the first positioning seat is mounted on the first rail and movable along the first rail in a first straight line, and the second positioning seat is mounted on the second rail and movable along the second rail in a second straight line.

12. A cutting device, comprising:
a motor; and
the cutter head according to claim 1 ,
wherein a driving shaft of the motor is connected to the double curved surface member of the cutter head by a flat key, so as to drive the double curved surface member to rotate.
