[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] A tightening and pushing-out device for a winding machine comprises a tightening device and a pushing-out device.

[0050] 1. Tightening device

[0051] The clamping device includes a linear guide cylinder a3A, a clamping cylinder component 9A, a shaft a6A, a clamping cone head a7A, a clamping cone head b13, a rotating shaft b14, a mounting cylinder 15 and a motor b17. The clamping cone head a7A and the clamping cone head b13 are coaxially arranged facing each other.

[0052] like Figure 16-Figure 18 As shown, the linear guide cylinder a3A is fixedly set on the turntable a1A, and the linear guide cylinder a3A includes a cylinder body 3A1 and an end cover 3A3, and the end cover 3A3 is fixed to the first end of the cylinder body 3A1; the clamping cylinder component 9A includes a cylinder body 9A2 and a piston rod 9A4, and the outer periphery of the cylinder body 9A2 is fixedly provided with a guide cylinder 9A1, and the guide cylinder 9A1 is slidably connected with the cylinder body 3A1 through a copper sleeve a4A, and the copper sleeve a4A is embedded in the cylinder body 3A1; the piston rod 9A4 is fixedly connected to the end cover 3A3; the shaft a6A is fixedly connected to the guide cylinder 9A1, and the clamping cone head a7A is rotatably connected with the shaft a6A through a rolling bearing a5A; the clamping cone head a7A is close to the second end of the cylinder body 3A1. The cylinder body 9A2 is provided with a fluid channel Ⅰ9A21, which is connected to the inner cavity Ⅰ of the cylinder body 9A2. The outer periphery of the cylinder body 9A2 is provided with a fluid inlet and outlet Ⅰ9A3, which is connected to the fluid channel Ⅰ9A21; the piston rod 9A4 is provided with a fluid channel Ⅱ9A41, which is connected to the inner cavity Ⅱ of the cylinder body 9A2, and the outer end of the piston rod 9A4 is provided with a fluid inlet and outlet Ⅱ9A5, which is connected to the fluid channel Ⅱ9A41. The fluid inlet and outlet Ⅰ9A3 and the fluid inlet and outlet Ⅱ9A5 are connected to the fluid power source through a reversing solenoid valve. If the liquid is oil, the fluid power source is a hydraulic station; if the liquid is compressed air, the fluid power source is an air compressor. The outer periphery of the cylinder body 3A1 is provided with a long round through hole 3A2, and the fluid inlet and outlet Ⅰ9A3 passes through the long round through hole 3A2.

[0053] like Fig.10 As shown, the mounting cylinder 15 is fixedly arranged on the turntable b1B, the rotating shaft b14 is rotationally connected to the mounting cylinder 15 via a rolling bearing b16, the clamping cone head b13 is coaxially fixedly connected to the rotating shaft b14, and the rotation of the rotating shaft b14 is driven by a motor b17.

[0054] 2. Push-out device

[0055] For a winder that does not stop for coil changing, there are generally two clamping cone heads b13 on the turntable b1B. In this embodiment, each clamping cone head b13 is equipped with a push-out device, such as Fig.10 and Fig.11 As shown, in this embodiment, the ejection device is a push component 19, which includes a push rod 191 and an automatic reset mechanism; a linear push-pull component 18 is used to push the push component 19 in the direction of the clamping cone head a7A, and the automatic reset mechanism is used to automatically restore the push component 19 to its original position. The linear push-pull component 18 is fixedly connected to the mounting frame 20, and the mounting frame 20 and the turntable b1B are arranged on the frame on the same side. There is only one linear push-pull component 18 on the mounting frame 20, as shown in FIG. Figure 3 As shown. The linear push-pull member 18 is an electric screw, a cylinder or a hydraulic cylinder. The two push-pull members 19 corresponding to the two clamping cone heads b13 on the turntable b1B share one linear push-pull member 18, and the linear push-pull member 18 specifically acts on the push-pull member 19 located at the roll changing position. Such a setting is more reasonable in terms of both mechanical structure and electrical control.

[0056] The pushing component 19 also includes a guide member 192 and a force transmission frame 194 . The guide member 192 is fixedly connected to the turntable b1B. The push rod 191 is slidably connected to the guide member 192 . The push rod 191 is fixedly connected to the force transmission frame 194 . The automatic reset mechanism is specifically as follows: a limiting flange I1921 is provided on one end of the guide member 192 facing the force transmission frame 194, a limiting flange II1941 is provided on one end of the force transmission frame 194 facing the guide member 192, a compression spring I193 is sleeved on the outer periphery of the push rod 191, and the compression spring I193 is located between the limiting flange I1921 and the limiting flange II1941; the force transmission frame 194 is slidably connected with the bracket 21, the bracket 21 is fixedly connected with the turntable b1B, a spring limiting member I195 is fixedly provided on the bracket 21, a spring limiting member II197 and a guide column 1971 are fixedly provided on the force transmission frame 194, a compression spring II196 is provided between the spring limiting member I195 and the spring limiting member II197, and the compression spring II196 is sleeved on the guide column 1971. The force transmission frame 194 and the bracket 21 are slidably connected through a slider 198 and a linear guide rail 199.

[0057] In order to realize automatic removal of the fully loaded winding core 22, a limit stop 8A1 is provided on the bracket a8A. The limit stop 8A1 is close to the clamping cone a7A and is parallel to the end face of the clamping cone a7A facing the clamping cone b13.

[0058] Use of this embodiment:

[0059] 1. When a new winding core 22 is needed, the winding core 22 is placed on the bracket a8A and the bracket b12 on the turntable a1A and the turntable b1B, which are located at the winding changing position respectively. The clamping cone a7A is inserted into the opening at one end of the winding core 22 through the relative sliding of the cylinder body 9A2 and the piston rod 9A4 of the clamping cylinder component 9A, and the winding core is gradually pushed toward the clamping cone b13, so that the clamping cone b13 is inserted into the opening at the other end of the winding core 22, thereby achieving the clamping of the winding core 22.

[0060] 2. When the fully loaded winding core 22 needs to be removed, the clamping cone head a7A is withdrawn from the winding core 22 by the relative sliding of the cylinder body 9A2 and the piston rod 9A4 of the clamping cylinder component 9A. At this time, one of the following two situations may occur:

[0061] The first case: there is a gap between the clamping cone head a7A and the winding core 22, and the clamping cone head a7A can be withdrawn from the winding core 22 by itself; then, the linear push-pull member 18 is used to make the pushing member 19 push the winding core 22 in the direction of the clamping cone head a7A, so that the clamping cone head b13 is withdrawn from the winding core 22.

[0062] The second situation: the clamping cone a7A is too tightly connected to the winding core 22, and the clamping cone a7A cannot be withdrawn from the winding core 22 by itself, but moves with the winding core 22. At this time, due to the existence of the upper limit stop 8A1 of the bracket a8A, the winding core 22 and the clamping cone a7A will be prevented from continuing to move, thereby realizing the smooth separation of the clamping cone a7A and the winding core 22. Then, the linear push-pull member 18 is used to make the pushing component 19 push the winding core 22 in the direction of the clamping cone a7A, so that the clamping cone b13 is withdrawn from the winding core 22 (regardless of whether the clamping cone b13 is still in the winding core 22 at this time, the pushing component 19 is pushed by the linear push-pull member 18, and there is no need to add a judgment function).

[0063] In the description of the present invention, words indicating orientation or positional relationship such as "inside", "outside", "upper", "lower", "front", and "back" are only used to facilitate the description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0064] The above is only one embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications made without departing from the idea of ​​the present invention are all within the protection scope of the present invention.
