[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0045] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] See also Figure 1 and Figure 2 Now, the zero return method of the rotary cutting machine provided in the embodiment of the present application is described. The zero return method of the rotary cutting machine provided in the embodiment of the present application is applied to the rotary cutting machine, and the rotary cutting machine includes a rotary driving member 10 and a cutting head 20 arranged on the rotary driving member 10. The zero return method of the rotary cutting machine provided in the embodiment of the present application includes steps S200, S400, S600, and S800.

[0048] S200, the rotary driving member rotates in a positive direction by a first preset angle.

[0049] The rotating drive member may be a motor. The "first preset angle" is a set angle.

[0050] S400: Determine whether the first origin switch senses the first origin signal.

[0051] S600: If yes, the rotary drive member rotates in the negative direction to find the second origin switch.

[0052] S800: If the second origin switch senses the second origin signal, the rotary drive component rotates in the negative direction by a second preset angle and then stops.

[0053] When the second origin switch senses the second origin signal, the rotary drive member rotates in the negative direction by a second preset angle and then stops rotating. At this time, the rotary drive member returns to the origin position.

[0054] The embodiment of the present application provides a method for returning to zero for a rotary cutting machine, which involves first rotating the rotary driving member in a positive direction by a first preset angle, and then determining whether the first origin switch senses a first origin signal. If so, the rotary driving member rotates in a negative direction to find a second origin switch. If the second origin switch senses a second origin signal, the rotary driving member rotates in a negative direction by a second preset angle and then stops, thereby achieving the return to zero of the rotary driving member. The position of the second origin switch is found through the first origin switch, and then the return to zero of the rotary driving member is achieved through the second origin switch, thereby improving the return to zero accuracy.

[0055] Specifically, a sensing sheet may be provided on the driving shaft of the rotating driving member. By setting the first origin switch, the relative position relationship between the second origin switch and the sensing sheet may be determined by determining whether the first origin switch senses the first origin signal. If the first origin switch senses the first origin signal, it indicates that the sensing sheet is located in the positive direction of the second origin switch. If the first origin switch does not sense the first origin signal, it indicates that the sensing sheet is located in the negative direction of the second origin switch.

[0056] When the first origin switch senses the first origin signal, when the rotary drive member rotates in the negative direction, the sensing piece also rotates in the negative direction synchronously, so that the sensing piece can sense each other with the second origin switch.

[0057] The zero return method of the rotary cutting machine may further include steps S710 and S720.

[0058] S710: If the first origin switch cannot sense the first origin switch signal, the rotary driving component rotates in the positive direction by a third preset angle.

[0059] When the first origin switch cannot sense the first origin signal, the rotating driving member can be rotated in the positive direction by a third preset angle. When the rotating driving member is rotated in the positive direction by the third preset angle, the rotating driving member can sense the first origin signal again. At this time, the sensing plate is located in the positive direction of the second origin switch.

[0060] S720, jump to step S400 "determine whether the first origin switch senses the first origin signal".

[0061] When the rotary driving member rotates in the positive direction by the third preset angle, the process jumps to step S400 for determination.

[0062] If the first origin switch still cannot sense the first origin switch signal after the rotary drive member rotates by the third preset angle in the positive direction, an alarm is issued.

[0063] If the first origin switch still cannot sense the first origin switch signal after the rotary drive member rotates in the positive direction by the third preset angle, it indicates that an error may have occurred, and an alarm is issued to prompt the staff to handle it.

[0064] Specifically, the third preset angle is 10° to 30°, for example, it may be 10°, 20° or 30°.

[0065] See also Figure 2 and Figure 5The rotary cutting machine also includes a frame 30, a cable (not shown), a drag chain 40, and a drag chain plate 50. The cable is installed in the drag chain 40. One end of the drag chain 40 is connected to the cutting head 20, and the other end is wound around the drag chain plate 50 and connected to the frame 10. The drag chain plate 50 is movably arranged on the frame 30 along a first direction and a second direction, and is used to tighten one end of the drag chain 40 connected to the cutting head 20. The first direction is opposite to the second direction. Specifically, in this embodiment, the "first direction" is a direction that is inclined downward, and the "second direction" is a direction that is inclined upward.

[0066] like Figure 3 As shown, step S800 "if the second origin switch senses the second origin signal, the rotating driving member rotates in the negative direction by a second preset angle and then stops", can also include steps S900 and S1000.

[0067] S900, the drag chain plate moves along the first direction to find the third origin switch.

[0068] S1000: If the third origin switch senses the third origin signal, the drag chain stops moving.

[0069] After the third origin signal is sensed by the third origin switch, the drag chain disk stops moving, and the drag chain disk returns to zero.

[0070] Since the drag chain disk is reset first and then the rotary drive member is reset, the cable is easily over-tightened and damaged. Therefore, the embodiment of the present application can avoid pulling the cable by first performing the zero return operation of the rotary drive member and then performing the zero return operation of the drag chain disk.

[0071] The first preset distance moved by the drag chain plate in the first direction and the circumference corresponding to the rotation of the rotary drive member in the negative direction by the second preset angle may be equal, that is, the drag chain plate and the rotary drive member have the same stroke, and synchronous movement of the drag chain plate and the rotary drive member can be achieved.

[0072] See also Figure 3 , step S200 "rotating the driving member in a positive direction by a first preset angle" may also include step S100:

[0073] S100, the drag chain plate moves a second preset distance along a second direction.

[0074] Before performing the zero return operation on the rotary drive component, the drag chain plate is first moved along the second direction by a second preset distance.

[0075] See also Figure 4 The working steps of one specific embodiment of the zero return method of the rotary cutting machine of the present application are as follows:

[0076] The drag chain plate (B axis) moves a second preset distance along a second direction (positive direction).

[0077] The rotary driving member (A-axis) rotates in a positive direction by a first preset angle.

[0078] It is determined whether the first origin switch senses the first origin signal.

[0079] If yes, the rotary drive member (A-axis) rotates in the negative direction to find the second origin switch.

[0080] If the second origin switch senses the second origin signal, the rotary driving member rotates in the negative direction by a second preset angle (a preset offset distance) and then stops.

[0081] The drag chain disk (B axis) moves along the first direction (negative direction) to find the third origin switch.

[0082] If the third origin switch senses the third origin signal, the drag chain stops moving.

[0083] If the first origin switch cannot sense the first origin switch signal, the rotary drive member rotates in the positive direction by the third preset angle (20°), and the drag chain moves in the second direction by the third preset distance (the circumference corresponding to 20°), and the third preset distance is equal to the circumference corresponding to the rotary drive member rotating in the positive direction by the third preset angle. Then, jump to the step "determine whether the first origin switch senses the first origin signal".

One end of the drag chain 40 is connected to the cutting head 20, and the other end is wound around the drag chain plate 50 and connected to the frame 30. The drag chain plate 50 is movably arranged on the frame 30 along a first direction and a second direction, and is used to tighten one end of the drag chain 40 connected to the cutting head 20.
