[0021] The present invention is further described in detail below with reference to the embodiments.

[0022] This embodiment provides a linkage automatic trimming device, such as Figure 1As shown, it includes a bottom plate 1, and a left cutting mechanism and a right cutting mechanism are symmetrically arranged on the left and right sides of the bottom plate 1. The left and right cutting mechanisms both include a linear module 3 and a driving motor 15 for driving the linear module 3. The moving block of the linear module 3 moves along the front-back direction of the bottom plate 1, and a cantilever 15 parallel to the linear module 3 is fixedly connected to the moving block. A cutting motor 16 is fixedly connected to the free end of the cantilever 15, and a cutting blade 17 is provided on the rotating shaft of the cutting motor 16. The left and right cutting mechanisms both include a rotating base 4 rotatably connected to the bottom plate 1, and the linear module 3 is fixed on the rotating base 4. The rotating base 4 of the left cutting mechanism and the bottom plate 1 are rotated by a left rotating shaft 19, and the rotating base 4 of the right cutting mechanism and the bottom plate 1 are rotated by a right rotating shaft 18.

[0023] The left and right sides of the bottom plate 1 are provided with a symmetrically arranged left arc guide rail 2 and right arc guide rail 14, the left arc guide rail 2 takes the left rotating shaft 19 as the center, and the right arc guide rail 14 takes the right rotating shaft 18 as the center, the rotating base 4 of the left cutting mechanism is provided with a left slide groove matched with the left slide rail, and the rotating base 4 of the right cutting mechanism is provided with a right slide groove matched with the right slide rail. The setting of the arc guide rail provides a guiding function for the rotation of the rotating base 4.

[0024] In order to realize the automatic rotation of the rotating base 4, a bidirectional screw 8 arranged along the left and right directions of the bottom plate 1 is provided between the left and right cutting mechanisms in this embodiment. The left end of the bidirectional screw 8 is threadedly connected with a positive thread sleeve 7 rotatably connected to the left cutting mechanism, and the right end of the bidirectional screw 8 is threadedly connected with a reverse thread sleeve 12 rotatably connected to the right cutting mechanism. The positive thread sleeve 7 and the rotating base 4 of the left cutting mechanism are rotated through the left rotating shaft 2 6, and the reverse thread sleeve 12 and the rotating base 4 of the right cutting mechanism are rotated through the right rotating shaft 2 13. A translation base 10 slidably connected to the bottom plate 1 is provided in the space between the left and right cutting mechanisms of the bottom plate 1. The translation base 10 slides up and down along the bottom plate 1 and a driving motor 2 11 for driving the double-headed screw to rotate is provided on the translation base 10.

[0025] like Figure 2 As shown, it is a schematic diagram of the extension of the cantilever 15. Under the action of the driving motor 15, the moving block on the linear module 3 moves along the linear module 3, thereby driving the cantilever 15 to translate. The linear modules 3 of the left and right cutting mechanisms act at the same time, driving the two cantilevers 15 to move along the front and rear directions of the base plate 1 at the same time. The cutting motor 16 drives the cutting blade 17 to rotate, realizing bilateral synchronous cutting.

[0026] like Figure 3As shown, it is a schematic diagram of the rotation of the cantilever 15, the driving motor 11 drives the bidirectional screw 8 to rotate, and the positive thread sleeve 7 and the reverse thread sleeve 12 move synchronously inward or outward under the action of the bidirectional screw 8; the left cutting mechanism rotates along the left circular arc guide 2 around the left rotation axis 19 under the drive of the positive thread sleeve 7; the right cutting mechanism rotates along the right circular arc guide 14 around the right rotation axis 18 under the drive of the reverse thread sleeve 12; and the positive and reverse thread sleeves 7, 12 are always kept in the same straight line with the bidirectional screw 8 under the action of the left and right rotation axes 6, 13. The transmission between the driving motor 11 and the bidirectional screw 8 can be realized by gear or synchronous belt transmission.

[0027] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
