The annular cutter is fixedly installed on the upper end surface of the workbench, and the discharge hopper is fixedly installed on the bottom surface of the workbench.

[0003] The prior art cuts the positive electrode material of the battery into shape by driving the cutter to move up and down. Although the prior art can complete the cutting of the material, the prior art is more dangerous when cutting. Because when the cutter of the prior art is pressed down, if the worker needs to adjust the position of the material at this time, the cutter will have a great probability of cutting the worker's hand and injuring the worker. Therefore, the prior art is more dangerous when working.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0010] As a preferred embodiment of the utility model, the protective structure also includes an alignment groove, a spring and a push plate. The alignment groove is symmetrically arranged at the bottom of the lifting box, the spring is fixedly connected in the alignment groove, the push plate is fixedly connected to the bottom of the spring, and the round tube cutter is fixedly connected in the alignment groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1.

The protective structure can prevent injuries to workers when battery materials are formed.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lifting motor 21 is symmetrically fixedly connected to the two sides of the operating platform 20, the bottom of the top plate 30 is fixedly connected to the top of the symmetrical lifting motor 21, the bottom of the protective plate 36 is flush with the top of the operating platform 20, and the protective plate 36 is symmetrically arranged at the bottom of the top plate 30. The protective structure also includes a lifting box 31, a spring groove 32, a slide plate 33, a fixed plate 34 and a spring plate 35. The lifting box 31 is fixedly connected to the bottom of the top plate 30, and the spring groove 32 is symmetrically opened on the top of the lifting box 31.

The spring plate 35 is fixedly connected to the side wall of the slide plate 33. The protective plate 36 is fixedly connected to the bottom of the slide plate 33. The spring plate 35 is spring-loaded in the spring groove 32. The slide plate 33, the fixed plate 34 and the spring plate 35 are symmetrically arranged on the wall surface of the lifting box 31, the round tube cutter 40 is fixedly connected to the bottom of the lifting box 31, and the protective structure also includes an alignment groove 37, a spring 38 and a push plate 39. The alignment groove 37 is symmetrically opened at the bottom of the lifting box 31, the spring 38 is fixedly connected in the alignment groove 37, the push plate 39 is fixedly connected to the bottom of the spring 38, the round tube cutter 40 is fixedly connected in the alignment groove 37, the position and number of the round tube cutter 40, the spring 38 and the push plate 39 are consistent with the alignment groove 37, the round tube cutter 40 is in the shape of a hollow round tube, the spring 38 is in the round tube cutter 40 and is fixedly connected to the bottom of the spring groove 32, and the push plate 39 is fixedly connected to the spring 38 in the cavity of the round tube cutter 40;

[0029] When in use, the positive electrode material to be cut is placed on the top of the operating table 20, and is made to slide on the top wall of the operating table 20. At this time, the power is turned on, and the lifting motor 21 drives the top plate 30 to move vertically up and down, and the top plate 30 drives the lifting box 31 to move vertically at the same time, and the lifting box 31 drives the slide plate 33 to move, and the slide plate 33 can drive the spring plate 35 to move in the spring groove 32, and the spring plate 35 is connected in the spring groove 32 by a spring, and the slide plate 33 can also drive the protective plate 36 to move. When the protective plate 36 moves, the bottom will contact the top of the material on the top of the operating table 20, and the lifting box 31 can also drive the round tube cutter 40 to move when moving, and the round tube cutter 40 will cut the material into a circle when moving, and after the round tube cutter 40 finishes cutting, the push plate 39 will be pushed by the spring 38, so that the material falls from the top of the round tube cutter 40 cavity into the guide tube 24 cavity;

[0030] To summarize, by setting up a protective structure, the circular tube cutter 40 can be prevented from cutting the worker's hands when the device is cutting materials, because the protective device can block the circular tube cutter 40 when the circular tube cutter 40 cuts materials, thereby preventing the worker's hands from reaching into the bottom of the circular tube cutter 40, and when the protective plate 36 blocks the circular tube cutter 40, the protective plate 36 can also fix the material to prevent it from sliding and affecting the cutting effect. Therefore, compared with the prior art, this solution is safer when used.

The front wall of the operating table 20 is open, and the top of the operating table 20 is also symmetrically fixedly connected with a bullet box 22, and the wall of the bullet box 22 is elastically connected with a roller 23;

[0032] In actual use, the cut material will pass through the guide tube 24 and fall into the cavity of the operating table 20, and then slide out of the device along the slope of the operating table 20;

[0033] In summary, by setting up the sloped cavity of the operating table 20, it is possible to prevent the material from being damaged due to collision after being cut, thereby increasing costs, because the material has only a small drop in the cavity of the operating table 20 and then slides out of the device, and when the material slides on the top of the operating table 20, the roller 23 will also contact the top of the material, thereby improving the smoothness of the sliding of the material.
