[0040] The present application is further described in detail below with reference to the accompanying drawings.

[0041] Reference Figure 1 The embodiment of the present application discloses a coil cutting tool, including a frame 1, a lower base 2, a polished rod 3, an upper base 4 and a spring 5.

[0042] The lower base 2 is rotatably connected to the frame 1 via a bearing, and the rotation axis is vertical. The lower base 2 and the frame 1 can be connected via a bearing to reduce rotation friction.

[0043] The polished rod 3 is located directly above the lower base 2, and the axis of the polished rod 3 coincides with the rotation axis of the lower base 2. The polished rod 3 is connected to the frame 1 in a vertical sliding manner.

[0044] A linear bearing can be provided between the polished rod 3 and the frame 1 to reduce friction. The upper end of the polished rod 3 can be held by a person to manually drive the polished rod 3 to move.

[0045] The upper base 4 is rotatably connected to the lower end of the polished rod 3, and the rotation axis of the upper base 4 coincides with the rotation axis of the lower base 2. The upper base 4 and the polished rod 3 are axially fixed. The upper base 4 and the polished rod 3 can be connected by a bearing to reduce rotational friction.

[0046] The spring 5 is sleeved on the outside of the polished rod 3 and is connected between the polished rod 3 and the frame 1. The spring 5 makes the polished rod 3 have a tendency to move downward.

[0047] Manually drive the polished rod 3 upward and place the coil between the lower base 2 and the upper base 4. The lower end of the coil touches the upper surface of the lower base 2. Release the polished rod 3. The spring 5 makes the upper base 4 touch the upper end of the coil, and the upper base 4 and the lower base 2 clamp the coil.

[0048] The coil cutting tool further comprises a blade 6 and a drive mechanism 7 .

[0049] The driving mechanism 7 is used to drive the blade 6 to translate along the direction A, which is parallel to the rotation axis of the lower base 2. The blade 6 is provided with cutting edges at both ends along the direction A. In the accompanying drawings, the blade 6 is double-sided beveled.

[0050] The driving mechanism 7 includes a rodless cylinder 71 , a fixing block 72 , an operating switch 73 and a controller.

[0051] The rodless cylinder 71 is used to drive the fixed block 72 to translate relative to the frame 1 along the A direction. The fixed block 72 is used to mount the blade 6. The controller responds to the signal of the operating switch 73 to control the rodless cylinder 71 to move once (up or down once).

[0052] The coil cutting tool of this embodiment utilizes a drive mechanism 7 to move a blade 6 to cut the coiled material evenly (avoiding skewed cutting). Blades are located at both ends of the blade along the A axis. Blade 6 does not need to be reset after completing a cut. This allows workers to cut thin films as needed, ensuring a convenient, quick, and safe operation.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
