Claims

1. A ring cutting mechanism, characterized by, The ring-cutting mechanism is used to perform film ring-cutting on the roll assembly. The roll assembly includes a roll body and a film layer covering the outer surface of the roll body. The film layer includes an end-face film covering the end face of the roll body. The ring-cutting mechanism includes: A first rolling drive assembly is capable of contacting the coil assembly located at the ring cutting station and is used to drive the coil assembly to rotate about the central axis of the coil assembly. At least one ring-cutting assembly is located at at least one end of the roll assembly at the ring-cutting station, and each ring-cutting assembly is used to separate the end face film of the corresponding end face of the roll body from the end face.

2. The ring cutting mechanism of claim 1, wherein, The first scrolling drive component includes: A first support roller and a second support roller, the first support roller and the second support roller together support the roll assembly located at the circumferential cutting station; The first rolling drive is connected to the first support roller. The first rolling drive drives the first support roller to rotate, thereby causing the material roll assembly to rotate around the central axis of the material roll assembly.

3. The ring cutting mechanism of claim 1, wherein, Each of the said circumferential cutting components includes: The piercing assembly includes a piercing member and a first reciprocating drive member connected to the piercing member. The first reciprocating drive member is capable of driving the piercing member to pierce between the end face and the end face film from the outer peripheral side of the end face of the roll body. The first cutting assembly includes a first cutter and a second reciprocating drive connected to the first cutter. The second reciprocating drive is capable of driving the first cutter to be inserted from the outer periphery of the end face of the roll body between the end face and the end face film.

4. The ring cutting mechanism of claim 3, wherein, The second reciprocating drive unit drives the first cutter to move radially along the material roll body, and the reciprocating movement direction of the piercing member intersects with the reciprocating movement direction of the first cutter.

5. The ring cutting mechanism of claim 3, wherein, The first cutter is a roller component, and the outer peripheral edge of the roller component has a cutting edge.

6. The ring cutting mechanism of claim 3, wherein, Each of the circumferential cutting components further includes: The first movable frame, wherein the puncture assembly and the first cutting assembly are mounted on the first movable frame; A first linear drive unit is connected to the first movable frame. The first linear drive unit is used to drive the first movable frame to move along the axial direction of the roll assembly, so as to drive the piercing assembly and the first cutter assembly to move closer to or away from the end face of the roll body.

7. The ring cutting mechanism of claim 6, wherein, Each of the circumferential cutting components further includes: A positioning sensor, connected to the first movable frame, is configured to be triggered when the piercing member and the first cutter move along the axial direction of the roll assembly to the end face of the roll body, and to generate a first positioning signal. The first linear drive member can pause its drive motion based on the first positioning signal.

8. The ring cutting mechanism of claim 7, wherein, Each of the circumferential cutting components further includes: A third reciprocating drive is disposed on the first movable frame, and the positioning sensor is mounted on the third reciprocating drive. The third reciprocating drive can drive the positioning sensor to a detection position or an avoidance position. In the detection position, at least a portion of the orthographic projection of the positioning sensor onto the plane containing the end face of the roll body is located within the end face. In the avoidance position, the orthographic projection of the positioning sensor onto the plane containing the end face of the roll body is located outside the end face.

9. The ring cutting mechanism of claim 1, wherein, The circumferential cutting mechanism further includes: The first pressing assembly includes a first pressing roller and a fourth reciprocating drive member. The fourth reciprocating drive member is connected to the first pressing roller and is used to drive the first pressing roller to a first separation position or a first pressing position. In the first separation position, the first pressing roller and the material roll assembly are spaced apart from each other. In the first pressing position, the first pressing roller contacts the circumferential surface of the material roll assembly and presses the material roll assembly against the first rolling drive assembly.

10. A film remover characterized by comprising: Includes the circumferential cutting mechanism as described in any one of claims 1 to 9.
