Abstract

The utility model discloses an edge-cutting device of a battery pole-piece, which mainly comprises a frame (1), an upper cutter (5), a lower cutter (6), a lower cutter shaft (7), a speed reducing machine (2) and a motor (3), wherein the lower cutter shaft (7) is connected with the speed reducing machine (2); the frame (1) is a whole frame structure; the upper cutter (5) is arranged on a cross beam (11) of the frame; and a bearing arranged at the bearing position of the lower cutter shaft (7) is arranged on a vertical plate (12) of the frame. In the utility model, the frame adopts the whole frame structure, the rigidity coefficient is increased, the strength and the stability are good, the shearing precision of the cutter is improved, furthermore, the cutter can be replaced without disassembling the cutter shaft, alternatively, the spacing of the lower cutter can be adjusted by large range, the operation is simple and convenient and the safety is high.

Description

The battery pole piece trimming device

Technical field

The utility model relates to the trimming device that uses in a kind of battery pole piece production.

Background technology

At present, the structure of battery pole piece trimming device is generally and is installing two side plates that are parallel to each other on the frame, and upper cutter fixed head and lower cutter pedestal are located on the biside plate.The upper cutter fixed head is installing upper cutter, is installing lower cutter on the incision cutter shaft, and the incision cutter shaft links to each other with reductor by transmission device.Connect because the connected mode between frame and side plate, side plate and upper cutter fixed head, incision cutter shaft and the side plate is all bolt, so this rigidity of structure coefficient is little, intensity and poor stability cause the shear precision of lower cutter to descend greatly.In addition, current battery pole piece trimming device must be pulled down the incision cutter shaft just and can change or adjust when changing lower cutter or adjusting the lower cutter spacing on a large scale, and is very inconvenient in the operation.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the above problems, and a kind of shear precision height is provided, adjusts easy to operate battery pole piece trimming device.

The utility model battery pole piece trimming device mainly comprises frame, upper cutter, lower cutter, incision cutter shaft, reductor, motor, the incision cutter shaft links to each other with reductor, frame is made as the integral frame structure, upper cutter is located on the crossbeam of framework, and the bearing bracket stand of incision cutter shaft is located on the riser of framework.

As a kind of improvement of the present utility model, reductor is located on the riser, and the driving end of incision cutter shaft directly links to each other with reductor.

As another improvement of the present utility model, the bearing pedestal of incision cutter shaft non-transmision end is made as split-type structural, and bearing is made as the divergence type bearing.

As another kind of improvement the of the present utility model, the bearing of incision cutter shaft non-transmision end is made as NU type cylinder roller bearing, and in the non-transmision end bearing position hole dimension greater than hole dimension in the driving end bearing position.

Because frame of the present utility model adopts the integral frame structure, the riser of crossbeam, both sides and base plate and framework are connected as a single entity, upper cutter is installed on the crossbeam by dovetail mount, lower cutter directly is packed on the incision cutter shaft, the incision cutter shaft is located on the riser by bearing bracket stand, so just avoided original upper cutter fixed head, side plate, frame to connect the defective on the mechanical structure that is caused by bolt, the stiffness coefficient of general frame structure increases, therefore intensity and good stability have improved the shear precision of cutting knife.In addition, incision cutter shaft non-transmision end bearing pedestal be made as split-type structural, bearing is made as the divergence type bearing, such structure, can be under the situation of not pulling down slitter shaft disassembling only by non-transmision end bearing, bearing pedestal, be replaceable lower cutter, perhaps adjust the spacing of lower cutter on a large scale, simple to operation and safe.

Description of drawings

Fig. 1 is the utility model battery pole piece trimming device front view.

Fig. 2 is that A-A shown in Figure 1 is to view.

Embodiment

As shown in Figure 1 and Figure 2, the utility model battery pole piece trimming device mainly comprises upper cutter 5, lower cutter 6, reductor 2, motor 3, frame 1, frame 1 adopts the integral frame structure, be that the crossbeam 11 of framework top, the riser 12 of both sides all link as a whole with framework, upper cutter 5 is packed on the crossbeam 11 by dovetail mount 51, the bearing bracket stand of incision cutter shaft 7 bearing positions is located on the riser 12 at framework two ends, and this integral frame has improved the stiffness coefficient of structure.Install motor 3 and reductor 2 on the riser 12 of frame 1 one sides, motor 3 can adopt variable-frequency motor, and reductor 2 directly links to each other with the driving end of incision cutter shaft 7, to reduce transmission link, improves transmission accuracy.As shown in Figure 2, the bearing pedestal 71 of incision cutter shaft 7 non-transmision ends is made as split-type structural, bearing pedestal 71 is fixed on the riser 12 by bolt 72, bearing 73 adopts the divergence type bearing, as adopting NU type cylinder roller bearing, the interior cover of bearing, the separable dismounting of overcoat, hole dimension is greater than hole dimension in the driving end bearing position in the non-transmision end bearing position, like this, after disassembling the bearing pedestal 71, bearing 73 of non-transmision end, just can change lower cutter 6, spacer 8 or adjust the cutting knife spacing, and need not to pull down slitter shaft 7 by this end, very convenient.
