The winding mechanism can drive the diaphragm to rotate at high speed and cut the diaphragm at a fixed distance during the rotation, thereby cutting the diaphragm into the required size. However, the existing winding mechanism still has certain usage defects during the operation process.

[0003] The existing winding mechanism clamps the diaphragm through the winding needle structure during operation, and then drives the diaphragm to rotate counterclockwise through the winding needle structure.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In a specific embodiment, Figure 1-Figure 3 As shown, the basic use process of the clockwise winding mechanism is disclosed;

[0029] A mounting structure 1 and a winding structure 5 mounted outside the mounting structure 1;

[0030] The interior of the mounting structure 1 is provided with an opening and closing cylinder 2, a needle threading servo motor 3 and a mounting frame 4. The outside of the mounting frame 4 is fixedly mounted with the opening and closing cylinder 2 and the needle threading servo motor 3, and the opening and closing cylinder 2 and the needle threading servo motor 3 are respectively located at the left and right ends of the mounting frame 4;

[0031] A positioning structure 9 is provided at the end of the winding structure 5 away from the mounting structure 1, and a follower 10, a fixed column cam groove 11 and a fixed seat 14 are provided inside the positioning structure 9. The fixed seat 14 is fixedly connected to the end of the winding structure 5 away from the mounting structure 1, and a follower 10 is fixedly installed at the end of the fixed seat 14 away from the winding structure 5, and a fixed column cam groove 11 is provided at the end of the follower 10 away from the fixed seat 14.

[0032] When using the clockwise winding mechanism, it is necessary to first install the clockwise winding mechanism in the working position, and then the diaphragm can be wound by the mechanism. During this process, one end of the diaphragm is clamped by the outer needle 6 of the winding needle and the inner needle 7 of the winding needle, and the outer needle 6 of the winding needle and the inner needle 7 of the winding needle will revolve and rotate, and the winding process of the diaphragm is completed during the rotation. After the diaphragm is wound to the required length, it is sheared by the external mechanism, and the outer needle 6 of the winding needle and the inner needle 7 of the winding needle will continue to rotate and clamp and wind the diaphragm again, completing the reciprocating shearing and winding process of the diaphragm.

[0033] In one specific embodiment, Figure 1-Figure 5 As shown, it is disclosed that the winding mechanism can rotate clockwise;

[0034] The winding structure 5 is provided with an outer winding needle 6, an inner winding needle 7 and a locking mouth 8. The locking mouth 8 is fixedly mounted on the end of the fixing seat 14 away from the follower 10, and the inner winding needle 7 is fixedly mounted on the end of the locking mouth 8 away from the fixing seat 14, and the outer winding needle 6 is provided on the outer side of the inner winding needle 7.

[0035] The winding structure 5 is provided with a follower 18, a winding needle seat 19 and a closing ejector 20 inside. The winding needle seat 19 is fixedly mounted on the end of the winding needle inner needle 7 away from the fixed seat 14. The follower 18 is provided on the end of the winding needle seat 19 away from the winding needle inner needle 7. The closing ejector 20 is nested inside the follower 18. At the same time, the end of the closing ejector 20 away from the follower 18 is connected to the opening and closing cylinder 2.

[0036] The centers of the outer winding needle 6, the inner winding needle 7 and the closing needle 20 are on the same straight line, and the length of the outer winding needle 6 is shorter than the length of the inner winding needle 7;

[0037] A turntable 15, a center shaft 16 and a diaphragm positioning roller 17 are provided inside the winding structure 5, and the turntable 15 is rotatably installed on one end of the mounting frame 4 close to the positioning structure 9, and the center shaft 16 is rotatably installed inside the turntable 15, and the diaphragm positioning roller 17 is fixedly installed on the outside of the center shaft 16.

[0038] When the clockwise winding mechanism is used, the outer winding needle 6 and the inner winding needle 7 rotate inside the turntable 15. The conventional winding mechanism rotates counterclockwise during self-rotation, which expands the gap between the outer winding needle 6 and the inner winding needle 7 and the diaphragm positioning roller 17. The outer winding needle 6 and the inner winding needle 7 inside the present winding mechanism rotate clockwise during self-rotation, which reduces the gap between the outer winding needle 6 and the inner winding needle 7 and the diaphragm positioning roller 17. This makes it easier to control the diaphragm winding distance, shortens the diaphragm cutting distance, and effectively improves the accuracy of diaphragm cutting.

[0039] During the operation of the outer needle 6 and the inner needle 7 of the winding needle, the locking mouth 8 will locate the positions of the outer needle 6 and the inner needle 7 of the winding needle, and the servo motor 13 will control the output efficiency through the reducer 12, reducing the speed at which the follower 10 drives the fixed seat 14 and the winding structure 5 to rotate, and the follower 2 18 will rotate synchronously with the follower 10.

[0040] Based on the above embodiments, Figures 1-6 As shown, the process of reducing the vibration amplitude of the diaphragm by the winding mechanism is disclosed;

[0041] The interior of the positioning structure 9 is provided with a reducer 12 and a servo motor 13. The servo motor 13 follower 10 is located at one end away from the fixed seat 14, and the output end of the servo motor 13 is fixedly mounted with the reducer 12.

[0042] The centers of the reducer 12 , the servo motor 13 and the follower 10 are in the same horizontal straight line, and the reducer 12 and the fixed column cam groove 11 are located between the servo motor 13 and the follower 10 .

[0043] When the clockwise winding mechanism is used, the outer needle 6 and the inner needle 7 of the winding needle will rotate and drive the diaphragm to be wound. During the winding process, the diaphragm positioning roller 17 will contact the diaphragm, thereby shortening the distance between the diaphragm and the air, thereby reducing the vibration amplitude generated by the high-speed transmission of the diaphragm in the air, further improving the cutting accuracy of the diaphragm during the winding process, and increasing the overall practicality.
