Abstract

The utility model discloses a battery pole-piece press rolling device used for a battery pole-piece rolling machine, which belongs to the field of battery pole-piece manufacturing equipment. Rolls with a large roll diameter are used as working rolls, and more than two small roll shafts are used as supporting rolls to make the roll face of each of the small roll shafts directly contact and support the roll face of each of the working rolls so as to form an upper roll system and a lower roll system, wherein the upper roll system is fixed, and the lower roll system moves up and down following the pressing of a pressing device to adjust the pressure force between the two working rolls; the upper roll system and the lower roll system respectively use two small vertical rolls for completing the axial positioning; two synchronous power transmission shafts are used for respectively inputting pure torque for the two working rolls of the upper roll system and the lower roll system to transfer power. The utility model avoids the coaxiality errors of the rolls and the influence on the thickness uniformity of pressed and rolled objects caused by manufacturing errors of s bearing, and furthest improves the contact strength of parts and components; besides, the defect of the flexibility deformation of the rolls at the time of large-load wide-breadth press rolling is overcome, and the technological problems that the pressed and rolled objects are not thin, or the middle part of each of the pressed and rolled objects is thick and both sides are thin are solved.

Description

The battery pole piece rolling device

Technical field

The utility model belongs to battery pole piece manufacturing equipment scope, particularly is used for a kind of battery pole piece rolling device of battery pole piece rolling mill.

Background technology

Because natural energy resources crisis and ecological deterioration, novel energy such as ni-mh, lithium ion, zinc air fuel cell, solar cell and energy storage mode develop rapidly.The pole piece rolling equipment demand of batteries such as ni-mh, lithium ion, the empty fuel of zinc, the empty fuel of aluminium, the empty fuel of hydrogen is also soaring day by day for this reason, and especially the demand of the battery pole piece rolling mill of the wide roll surface in big roller footpath is more apparent urgent.Rolling device is the core component on the battery pole piece rolling mill.Conventional apparatus is subjected to the influence of roll coaxiality error, the bearing accuracy of manufacture, roll bending distortion and parts contact stiffness, the battery pole piece compression ratio that rolls out is little, became uneven, thick middle both sides thin, breadth is narrow or the like, seriously influence battery pole piece quality and production efficiency, and seriously made the lifting that elbow battery quality.

Summary of the invention

The purpose of this utility model provides a kind of battery pole piece rolling device that is used for battery pole piece rolling mill.It is characterized in that:

The roll surface of pony roll axle more than 1/3rd two of described battery pole piece rolling device put into bearing 8 inner rings of oil-free lubrication or watt formula, on the supporting object 2 that bearing pedestal is fixed on, supporting object 2 is connected with top strutting piece 1, and be fixed on the milling train framework, pony roll axle 3 roll surfaces directly contact and are supported on the roll surface of working roll 4, the working roll 4 of support top roll system avoids moving, and forms top roll system (avoiding top roll is that working roll 4 is a lot of because of the mode of deadweight whereabouts, and the utility model repeats no more); Supporting object 2 is connected with following strutting piece 1, and directly contacts and be supported on by pony roll axle 3 roll surfaces on the roll surface of working roll 4 of lower roll system, makes working roll 4 avoid moving down, and forms lower roll system; Lower roll system can exert pressure and moves up and down with device for exerting 7, regulates the pressure between two working rolls.Up-down rollers system respectively has two little edger rolls 6 to be fixed on the milling train framework, carries out axial location near the end face of working roll 4; Two synchronous dynamic transmission axles 5 transmit power to two working rolls 4 of up-down rollers system respectively.

Described synchronous dynamic transmission axle 5 is fixed on seam formula adpting flange 9 in the end face central authorities of working roll 4 by shearing resistance fastening bolt 10; Various oil-free lubrication connected modes such as this connection can also connect for key, riveting connection or welding.

The beneficial effects of the utility model are to abandon to disperse the tradition of load concentration in two end supports, with the design concept of disperseing the corresponding dispersion of load to support, have avoided roll coaxiality error, bearing foozle to being influenced by roll extrusion object thin and thick uniformity; Increased the contact strength between each parts to greatest extent, the deflection deformation of roll when having overcome big load wide format has solved by the roll extrusion object and has pressed technical barrier quite well and that the thick middle both sides are thin.
