Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the embodiments of the present invention, it should be noted that, if the terms "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings or the orientation or positional relationship which the product of the present invention is used to usually place, it is only for convenience of describing the present invention and simplifying the description, but it is not necessary to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the appearances of the terms "first," "second," and the like in the description of the present invention are only used for distinguishing between the descriptions and are not intended to indicate or imply relative importance.

In the description of the embodiments of the present invention, it should be further noted that unless otherwise explicitly stated or limited, the terms "disposed" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in the drawing, the utility model discloses an upper die base 25 and die holder 26 are equipped with cope match-plate pattern 27 on the upper die base 25, are equipped with lower bolster 28 on the die holder 26, and are equipped with the clearance between lower bolster 28 and the die holder 26, are equipped with a set of recess that cuts that runs through from top to bottom on the lower bolster 28, are equipped with on the cope match-plate pattern 27 and cut recess complex cutting piece 29, through a set of guide arm swing joint between upper die base 25 and the die holder 26, die holder 26 bottom is equipped with the actuating cylinder that drives that drive upper die base 25 reciprocated.

A jacking plate connected with a group of guide rods is arranged in the lower die base 26, and the driving cylinder drives the upper die base 25 to move up and down through the jacking plate.

Furthermore, a material belt tensioning roller 30 is arranged on one side of the discharging end of the upper die base 25, a material belt guide roller 31 is arranged on one side of the discharging end of the lower die base 26, and the material belt tensioning roller 30 and the material belt guide roller 31 are not on the same vertical plane.

The cut rim charge passes through the material belt guide roller 31 for guiding, when cutting is carried out, the upper die base 25 drives the material belt tensioning roller 30 to move downwards, the material belt tensioning roller 30 has downward pressure on the pole piece material belt at the front end, the pole piece material belt in the die cutting device keeps flat, and the cutting quality is improved.

Furthermore, a pair of material belt tensioning roller installation seats 32 is arranged on the upper die base 25, vertical guide holes are formed in the material belt tensioning roller installation seats 32, and two ends of the material belt tensioning roller 30 are movably installed in the corresponding vertical guide holes through guide rollers respectively.

The material area props tight roller 30 and is the rubber roller, and the diameter of roller is 60mm, and the material area props tight roller 30 and can prop tight roller mount pad 32 internal upper and lower displacement in the material area for the control material area props the pressure size of tight roller 30 to the pole piece material area, prevents that pressure from too big destruction pole piece material from taking the coating on the area.

Furthermore, a group of air injection holes are arranged in the middle of the bottom of the cutting block 29, and an air adapter respectively communicated with the air injection holes on the cutting block 29 is arranged on the upper die base 25.

After cutting, the pole piece falls on the traction belt 8, and because the bottom of the cutting block 29 is attached to the pole piece, when the upper die base 25 is lifted upwards, the pole piece is easily lifted upwards, so that the pole piece is inclined, and rear-end collection is not facilitated. Through set up the fumarole on cutting block 29, the fumarole communicates with external air supply, and the fumarole jets downwards when cutting block 29 rises to the top, makes pole piece and cutting block 29 separation and tiling on traction belt 8 through atmospheric pressure, can improve cutting device's cutting frequency like this, does not worry that cutting block 29 rises fast and makes the pole piece crooked.

The working mode is as follows: pole piece material area tiling is on traction belt 8 to follow traction belt 8 and move forward, traction belt 8 passes from the clearance between lower bolster 28 and die holder 26, and the pole piece material area passes from the lower bolster 28 top, and when cutting, the pole piece falls on traction belt 8 with the rim charge separation, drives the pole piece when preventing the rim charge rolling and leads to crooked, and the pole piece of being convenient for is collected.
