Specific Embodiments

[0020] Please refer to the attached drawings of the specification Figure 1 to attached drawing Figure 4As shown, the utility model is a scissor mechanism of a fully automatic winding machine, which is used to cut the yarn 10 and consists of a mounting base 1, a scissor telescopic cylinder 2, a scissor base 3, a fixed blade 4, a movable blade 5, a connecting rod 6 and a scissor cylinder 7.

[0021] The mounting seat 1 is fixed on the frame 9 of the winding machine, so that the entire scissor mechanism is mounted on the frame 9.

[0022] The scissor telescopic cylinder 2 is installed in the mounting seat 1, which is connected to and pushes the scissor seat 3 so that the scissor mechanism can be retracted when it does not need to cut the yarn 10 (as shown in the attached manual). Figure 1 As shown, it is a state diagram when the scissors mechanism is retracted), to prevent the scissors from accidentally cutting the yarn 10 or conflicting with other mechanisms of the winding machine. Specifically, the scissors telescopic cylinder 2 includes a cylinder rod 21, and the cylinder rod 21 vertically passes through the mounting seat 1 and is connected to the scissors seat 3, and the scissors seat 3 is pushed to telescope through the cylinder rod 21. A guide rod 22 is respectively provided on both sides of the cylinder rod 21, and one end of the guide rod 22 is connected to the scissors seat 3 and supported on the mounting seat 1 through a linear bearing 23. The guide rod 22 limits the moving direction of the scissors seat 3 to prevent the scissors seat 3 from rotating.

[0023] The fixed blade 4 is fixedly mounted on the scissor seat 3 and moves in conjunction with the scissor seat 3. The movable blade 5 is pivotally connected to the scissor seat 3, and can rotate relative to the fixed blade 4, and cooperate with the fixed blade 4 to cut the yarn 10. That is, when the movable blade 5 and the fixed blade 4 are engaged, the yarn 10 is cut.

[0024] The scissor cylinder 7 is installed on one side of the scissor seat 3, and is connected to and drives the connecting rod 6 to extend and retract, thereby providing power for the shearing action of the scissor mechanism. Since only one scissor cylinder 7 is needed for driving, the structure of the scissor mechanism is simple and the cost is low.

[0025] The connecting rod 6 is pivotally connected to the movable blade 5 and can drive the movable blade 5 to open and close. Specifically, the movable blade 5 is provided with a waist hole 51, and the connecting rod 6 is provided with a pin 61, which is received in the waist hole 51 and pushes the movable blade 5 to open and close through the pin 61. Further, a plurality of guide blocks 31 are provided at the bottom of the scissor seat 3, and the connecting rod 6 passes through the guide blocks 31 to limit the moving direction of the connecting rod 6.

[0026] The movable blades 5 are provided with a plurality of blades, all of which are driven simultaneously by the same connecting rod 6. Since the connecting rod 6 drives the plurality of movable blades 5 simultaneously, the wire cutting efficiency is high, the actions are synchronized, and the labor intensity of the workers is greatly reduced. In this embodiment, the movable blades 5 are specifically provided with four blades, and are arranged at equal intervals; each movable blade 5 corresponds to a fixed blade 4.

[0027] The working principle of the scissors mechanism of the full-automatic winding machine of the present utility model is as follows: When it is necessary to cut the yarn 10, the scissors telescopic cylinder 2 drives the cylinder rod 21 to extend the cylinder rod 21, and the cylinder rod 21 drives components such as the scissors seat 3, the fixed blade 4 and the movable blade 5 mounted on the scissors seat 3. During the extension of the scissors mechanism, the telescopic direction of the scissors mechanism is defined by the guide rod 22. After the scissors mechanism extends, the yarn 10 enters between the fixed blade 4 and the movable blade 5. Then, the scissors cylinder 7 is activated and pulls the connecting rod 6, and the connecting rod 6 drives all the movable blades 5 in a linkage manner, so that the movable blade 5 closes relative to the fixed blade 4, thereby cutting the yarn 10.

[0028] The above specific implementation manners are only preferred embodiments of the present creation, and are not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present creation shall be included within the protection scope of the present creation.
