[0049] Reference Figure 3 and Figure 6The outer sleeve 323 is sleeved on the inner sleeve 321, and one end is rotatably connected to the inner wall of the cutting box 1. A plurality of limit teeth 324 are provided, and the plurality of limit teeth 324 are evenly arranged around the axis direction of the outer sleeve 323.

[0051] Reference Figure 2 and Figure 5 The driving part 33 includes a rotating gear 331, an incomplete gear 332, a driving motor 333, a driving wheel 334, a driven wheel 335 and a belt 336. The rotating gear 331 is coaxially fixed to the outer sleeve 323; the incomplete gear 332 is rotatably connected to the cutting box 1 through a connecting rod 3321, and the incomplete gear 332 is meshed with the rotating gear 331.

[0052] Reference Figure 2 and Figure 3 The driving motor 333 is fixed on the mounting frame on the ground; the driving wheel 334 is coaxially fixedly connected to the output shaft of the driving motor 333. The driven wheel 335 is coaxially fixedly connected to the connecting rod 3321. The two ends of the belt 336 are sleeved on the driving wheel 334 and the driven wheel 335. The driving wheel 334 and the driven wheel 335 are also covered with a protective shell 245.

[0053] When in use, the driving motor 333 is started, the output shaft of the driving motor 333 drives the driving wheel 334 to rotate, the driving wheel 334 drives the belt 336 to rotate, the belt 336 drives the driven wheel 335 to rotate, the driven wheel 335 drives the incomplete gear 332 to rotate, the incomplete gear 332 drives the rotating gear 331 to rotate, and the rotating gear 331 drives the outer sleeve 323 to rotate;

[0054] The outer sleeve 323 drives the baffle plate 14 to rotate, and the baffle plate 14 drives one end of the arc spring 325 to rotate, squeezing the arc spring 325. At the same time, the outer sleeve 323 drives the limit tooth 324 to rotate, and the limit tooth 324 is misaligned with the push tooth 322. Under the elastic force of the push spring 3211, the inner sleeve 321 moves toward the direction close to the rotating wheel 21, and the inner sleeve 321 drives the fixed disk 311 to move. The fixed disk 311 drives the movable disk 312 and the push rod 313 to move at the same time, and the push rod 313 pushes the magnesium strip to move;

[0055] When the incomplete gear 332 rotates away from the rotating gear 331, under the elastic force of the arc spring 325, the arc spring 325 drives the outer sleeve 323 to reset. At this time, the pushing tooth 322 and the limiting tooth 324 re-engage, limiting the movement of the fixed disk 311, ensuring that the length of the magnesium strip pushed each time is consistent, thereby improving the cutting accuracy.

[0056] Reference Figure 3 The cutting assembly 4 includes a fixed frame 41, an electric telescopic rod 42 and a cutting machine 43. The fixed frame 41 is fixedly connected to the cutting box 1.

The movable end of the electric telescopic rod 42 is vertically arranged downward and is electrically connected to the external controller. The cutting machine 43 is fixedly connected to the movable end of the electric telescopic rod 42.

[0057] When in use, the external controller controls the movable end of the electric telescopic rod 42 to move. When the magnesium bar moves to the bottom of the cutting machine 43, the movable end of the electric telescopic rod 42 extends and drives the cutting machine 43 to move. The cutting machine 43 cuts the magnesium bar, so that the cutting machine 43 can be adjusted in real time according to the cutting requirements, thereby easily ensuring the cutting accuracy.

[0058] The implementation principle of a magnesium bar cutting machine in the embodiment of the present application is as follows: a magnesium bar is placed between the clamping blocks 22, and under the action of the clamping spring 232, the clamping block 231 stably clamps the magnesium bar, and through the synchronous wheel group, the transmission motor 241 drives the rotating wheel 21 to rotate, and the rotating wheel 21 drives multiple magnesium bars to rotate simultaneously, and the movable end of the electric telescopic rod 242 is controlled to move by an external controller.

[0059] When the magnesium strip moves to the bottom of the cutting machine 43, the movable end of the electric telescopic rod 42 extends and drives the cutting machine 43 to move, and the cutting machine 43 cuts the magnesium strip, and multiple magnesium strips can be cut at one time;

[0060] During the rotation of the rotating wheel 21, the driving motor 333 drives the incomplete gear 332 to rotate through the driving wheel 334, the incomplete gear 332 drives the rotating gear 331 to rotate, the rotating gear 331 drives the outer sleeve 323 to rotate, the outer sleeve 323 drives one end of the arc spring 325 to rotate, squeezing the arc spring 325;

[0061] At the same time, the outer sleeve 323 drives the limiting latch 324 to rotate, and the limiting latch 324 is misaligned with the pushing latch 322. Under the elastic force of the pushing spring 3211, the inner sleeve 321 moves toward the direction close to the rotating wheel 21, and the inner sleeve 321 drives the fixed disk 311 to move. The fixed disk 311 drives the moving disk 312 and the push rod 313 to move at the same time, and the push rod 313 pushes the magnesium strip to move.

[0062] When the incomplete gear 332 rotates away from the rotating gear 331, under the elastic force of the arc spring 325, the arc spring 325 drives the outer sleeve 323 to reset. At this time, the pushing tooth 322 and the limiting tooth 324 re-engage, limiting the movement of the fixed plate 311, ensuring that the length of the magnesium bar pushed each time is consistent, thereby improving the cutting accuracy and further improving the processing efficiency of the magnesium bar.

[0063] Embodiment 2

[0064] Reference Figure 7 and 8 An electric telescopic rod 17 is fixedly connected to the inner wall of the cutting box 1, and the fixed plate 311 is driven to reset by the electric telescopic rod 17.

[0065] When in use, after the cutting is completed, the driving motor 333 is started again, and the incomplete gear 332 is meshed with the rotating gear 331 through the pulley transmission, and the limit tooth 324 and the propulsion tooth 322 are misaligned. The external controller controls the electric telescopic rod 17 to retract and drive the fixed disk 311 to reset; and the inner sleeve 321 is restored to its initial state, so as to facilitate the next propulsion, thereby greatly improving the processing efficiency.

[0066] Furthermore, a reset plate 171 is fixed on the electric telescopic rod 17, and the fixed disk 311 is driven to reset by the movement of the reset plate 171; when the electric telescopic rod 17 is retracted, the reset plate 171 contacts the fixed disk 311, thereby pushing the fixed disk 311 to reset. A sliding groove is provided on the fixed disk 311, which is slidably connected to the electric telescopic rod 17, and the sliding groove and the electric telescopic rod 17 can play a role in limiting the rotation of the fixed disk 311.

[0067] Furthermore, a moving sleeve 172 is fixedly connected to the front end of the electric telescopic rod 17, and a limiting sleeve 173 slidably connected to the rotating wheel 21 is rotatably connected inside the moving sleeve 172; when the magnesium bar is stably clamped, the electric telescopic rod 17 is extended so that the limiting sleeve 173 is sleeved on the outer side of the rotating wheel 21 that has clamped the magnesium bar. The limiting sleeve 173 can prevent the magnesium bar from falling off when the push rod 313 pushes the magnesium bar to move, and will not hinder the rotation of the rotating wheel 21 and the movement of the magnesium bar.
