Abstract

A passive intermittent rotating assembly can automatically adjust a part of a cleaning material when the cleaning material cleans a spinning jet each time and that can stably operate in a high-voltage environment. The passive intermittent rotating assembly includes a plurality of first abutment members and second abutment members being arranged respectively at an inner side and outer side of the main wheel along the circumferential direction, and being separated from each other to form gaps for a push portion of a push member to pass through. Each of the first abutment members includes a first inner-side abutment portion and a first outer-side abutment portion provided for abutting against the push portion. Each of the second abutment members includes a second inner-side abutment portion and a second outer-side abutment portion provided for abutting against the push portion.

First claim

What is claimed is:

1. A passive intermittent rotating assembly, comprising:
a cleaning material used for cleaning a spinning jet of a spinning device of an electrospinning equipment;
a front winding wheel and a rear winding wheel separately rotatably supported on the electrospinning equipment and provided for the cleaning material to be wound on;
a main wheel coaxially rotating with the front winding wheel, and abutment members being formed on an outer circumferential surface of the main wheel; and
a push member supported by the spinning device to move back and forth along an axial direction of the main wheel with the spinning jet, and in a process of moving back and forth, a push portion of the push member abutting against the abutment members and pushing the main wheel to rotate in a rotation direction, wherein
the abutment members comprise a plurality of first abutment members being arranged at an inner side of the main wheel along a circumferential direction, and being separated from each other to form first gaps for the push portion to pass through; and a plurality of second abutment members being arranged at an outer side of the main wheel along the circumferential direction, and being separated from each other to form second gaps for the push portion to pass through;
each of the plurality of first abutment members comprises a first inner-side abutment portion and a first outer-side abutment portion provided for abutting against the push portion and converging toward a direction opposite to the rotation direction of the main wheel;
each of the plurality of second abutment members comprises a second inner-side abutment portion and a second outer-side abutment portion provided for abutting against the push portion and converging toward the direction opposite to the rotation direction of the main wheel; and
when observing from the axial direction of the main wheel, there is no gap in the circumferential direction between the first inner-side abutment portion and two second inner-side abutment portions adjacent to the first inner-side abutment portion or there is only a gap smaller than a half length of the push portion in a horizontal direction, and there is no gap in the circumferential direction between the first outer-side abutment portion and two second outer-side abutment portions adjacent to the first outer-side abutment portion or there is only a gap smaller than the half length of the push portion in the horizontal direction.

2. The passive intermittent rotating assembly according to claim 1 , further comprising:
an adjusting rod configured to adjust a tension of the cleaning material wound on the front winding wheel and the rear winding wheel.

3. The passive intermittent rotating assembly according to claim 1 , wherein
each of the plurality of first abutment members has a first front-side abutment portion at a downstream side in the rotation direction of the main wheel;
each of the plurality of second abutment members has a second front-side abutment portion at the downstream side in the rotation direction of the main wheel;
the first front-side abutment portion and the second front-side abutment portion are formed in parallel to the axial direction of the main wheel; and
a diameter of the push portion is substantially the same as the first gap between two of the plurality of first abutment members and the second gap between two of the plurality of second abutment members.

4. The passive intermittent rotating assembly according to claim 3 , further comprising:
an adjusting rod configured to adjust a tension of the cleaning material wound on the front winding wheel and the rear winding wheel.

5. The passive intermittent rotating assembly according to claim 3 , wherein in a top view, the shape of each of the plurality of first abutment members is substantially an inverted triangle formed by the first inner-side abutment portion, the first outer-side abutment portion, and the first front-side abutment portion; and
in a top view, the shape of each of the plurality of second abutment members is substantially an inverted triangle formed by the second inner-side abutment portion, the second outer-side abutment portion, and the second front-side abutment portion.

6. The passive intermittent rotating assembly according to claim 1 , wherein
two ends of the second inner-side abutment portion in the circumferential direction are further forward and rearward respectively than the first gap between adjacent two of the plurality of first abutment members in the rotation direction of the main wheel; and
two ends of the first outer-side abutment portion in the circumferential direction are further forward and rearward respectively than the second gap between two adjacent of the plurality of second abutment members in the rotation direction of the main wheel.

7. The passive intermittent rotating assembly according to claim 6 , further comprising:
an adjusting rod configured to adjust a tension of the cleaning material wound on the front winding wheel and the rear winding wheel.

8. The passive intermittent rotating assembly according to claim 6 , wherein each of the plurality of first abutment members has a first front-side abutment portion at a downstream side in the rotation direction of the main wheel;
each of the plurality of second abutment members has a second front-side abutment portion at the downstream side in the rotation direction of the main wheel;
the first front-side abutment portion and the second front-side abutment portion are formed in parallel to the axial direction of the main wheel; and
a diameter of the push portion is substantially the same as the first gap between two of the plurality of first abutment members and the second gap between two of the plurality of second abutment members.

9. The passive intermittent rotating assembly according to claim 8 , further comprising:
an adjusting rod configured to adjust a tension of the cleaning material wound on the front winding wheel and the rear winding wheel.

10. The passive intermittent rotating assembly according to claim 8 , wherein
in a top view, the shape of each of the plurality of first abutment members is substantially an inverted triangle formed by the first inner-side abutment portion, the first outer-side abutment portion, and the first front-side abutment portion; and
in a top view, the shape of each of the plurality of second abutment members is substantially an inverted triangle formed by the second inner-side abutment portion, the second outer-side abutment portion, and the second front-side abutment portion.

11. An electrospinning equipment, comprising:
the passive intermittent rotating assembly according to claim 1 ;
