Description

Twin rollers rolling mill bearing gap eliminator

Technical field

The utility model relates to a kind of battery pole piece production equipments, carry out roll-in to dry powder more particularly, to double rolls and make At the twin rollers rolling mill bearing gap eliminator of battery pole piece part.

Background technique

It is currently that roll-in is carried out to dry powder with no electric heating double rolls and battery pole piece is made, roll-in bonding is carried out to dry powder Property is poor, and qualification rate is low.In order to which qualified battery pole piece is made, the revolving speed of roll must very slowly, and production efficiency is extremely low.In order to Improve the qualification rate of production efficiency and product, it is necessary to be heated with electrically heated rod to roll.According to the principle expanded with heat and contract with cold, roller After rolling heating, it can become larger, inner rings of rolling-mill bearings can also become larger.But wallboard and rolling mill bearing outer ring temperature do not become, size dimension Just do not become.Cause the spacing of rolling mill bearing outer ring and inner rings of rolling-mill bearings that can become smaller, as a result, rolling mill bearing roller is squeezed it is broken, Roll is stuck.In order to avoid rolling mill bearing roller be squeezed it is broken, then it is before assembly that the outer diameter of inner rings of rolling-mill bearings mill is small.Roll Heating temperature is constant, therefore the temperature of inner rings of rolling-mill bearings is also constant.But the temperature of wallboard and rolling mill bearing outer ring For room temperature, winter temperature is low, summer temperature is high, the result is that the spacing winter of rolling mill bearing outer ring and inner rings of rolling-mill bearings is small, the summer It is extremely big.After spacing is big, inner rings of rolling-mill bearings vibration in rolling mill bearing outer ring can be made, neglects the spacing T between two rolls Suddenly small greatly, cause the thickness of battery pole piece suddenly big or suddenly small, product quality is unqualified.

Utility model content

The purpose of this utility model is to solve the double rolls of existing no electric heating to carry out roll-in and manufactured battery pole to dry powder Piece, poor adhesion, qualification rate is low, the low problem of production efficiency.A kind of twin rollers rolling mill bearing gap eliminator is provided.It eliminates The phenomenon that inner rings of rolling-mill bearings vibration in rolling mill bearing outer ring avoids rolling mill bearing roller from being squeezed broken, and roll is stuck, makes to give birth to The battery pole piece thickness uniformity that output is come.

Used technical solution is to solve above-mentioned technical problem: twin rollers rolling mill bearing gap eliminator, including Wallboard, roll, inner rings of rolling-mill bearings, rolling mill bearing roller, rolling mill bearing outer ring, deep groove ball bearing are same in wallboard upper screwed hole Direction is equipped with disk spring, withstands disk spring with flush end holding screw, disk spring withstands deep groove ball bearing, deep groove ball bearing It covers in the outer circle of roll；Electrically heated rod is respectively arranged in two rolls, electrically heated rod is fixed on boring cover with plain washer and hex nut, Boring cover is screwed in wallboard；The outer circle of rolling is equipped with inner rings of rolling-mill bearings, and rolling mill bearing roller and milling train are housed outside it Bearing outer ring, rolling mill bearing outer ring are packed into wallboard hole.Disk spring in wallboard upper screwed hole has 4, and electrically heated rod is used flat Washer and hex nut are fixed on boring cover.

The utility model has the beneficial effects that the double rolls of electric heating carry out roll-in and manufactured battery pole piece to dry powder, glue Conjunction property is good.Since the transmitting of power makes roll and inner rings of rolling-mill bearings withstand rolling mill bearing roller, rolling mill bearing roller withstands milling train Bearing outer ring and wallboard.When becoming smaller in the spacing winter of rolling mill bearing outer ring and inner rings of rolling-mill bearings, the bullet of disk spring is utilized Property deformation offset, avoiding rolling mill bearing roller is squeezed broken, and roll is stuck.When in rolling mill bearing outer ring and rolling mill bearing It when the spacing hot day of circle becomes larger, is offset using the flexible deformation of disk spring, eliminates inner rings of rolling-mill bearings in milling train axis Vibration in bearing outer-ring, not only increases product quality, also improves production efficiency.Realize roll without vibration, without stuck, roll-in and At battery pole piece thickness uniformity.

Specific embodiment

The present invention will be further described with reference to the accompanying drawings and examples.

The utility model is the flexible deformation according to disk spring, eliminates inner rings of rolling-mill bearings in rolling mill bearing outer ring Vibration avoids rolling mill bearing roller and is squeezed broken, and the principle that roll is stuck is made.

As shown in Figure 1 and Figure 2, twin rollers rolling mill bearing gap eliminator, including wallboard 1, roll 2, driving gear 7 are put down Key 8, driven gear 9, electrically heated rod 10, hex nut 11, plain washer 12, boring cover 13, inner rings of rolling-mill bearings 14, rolling mill bearing rolling Column 15, rolling mill bearing outer ring 16, deep groove ball bearing 17.The both ends of double rolls 2 are put on into 4 dieback roll 2 of dustband, then by milling train Bearing inner race 14 heats the both ends for being inserted in double rolls 2 and dieback dustband 4.To the outer circle of 2 both ends inner rings of rolling-mill bearings 14 of roll It is ground, stock removal is under the coldest winter temperature, and roll 2 is heated under required maximum temperature, rolling mill bearing roller 15 are not squeezed broken, and roll 2 is not stuck.Indentation in the corresponding aperture of two sidewall panels 1 is had to the milling train axis of rolling mill bearing roller 15 Then two sidewall panels 1 are packed into the both ends of double rolls 2, then are pressed into zanjon in the both ends outer circle of double rolls 2 by bearing outer-ring 16 and on earth Ball bearing 17.17 sets of deep groove ball bearing in the outer circle of roll 2；Electrically heated rod 10 is packed into boring cover 13, puts on plain washer 12, screws in Hex nut 11 is simultaneously tightened.Electrically heated rod 10 is respectively arranged in two rolls 2, electrically heated rod 10 is fixed on boring cover 13, and boring cover 13 uses spiral shell Nail 5 is fixed on wallboard 1.The outer circle of rolling 2 is equipped with inner rings of rolling-mill bearings 14, and rolling mill bearing roller 15 and milling train axis are housed outside it Bearing outer-ring 16, rolling mill bearing outer ring are packed into 1 hole of wallboard.Transparent cover 6 is packed into the other end of roll 2, is fixed on wallboard with screw 5 On 1.It is equidirectional in 1 upper screwed hole of wallboard to fill 4 disk springs 18, it refills interior hexagonal flush end holding screw 19 and withstands disk spring 18.Disk spring 18 withstands deep groove ball bearing 17, and 17 sets of deep groove ball bearing in the outer circle of roll 2；The keyway of double rolls 2 is packed into Flat key 8, left roll 2 are packed into driving gear 7, and right roll 2 is packed into driven gear 9, and driving gear 7 drives after being entered turning moment 9 opposite direction rotating of driven gear carries out roll-in to dry powder and battery pole piece 3 is made.

Application method: due to the flexible deformation using disk spring 18, inner rings of rolling-mill bearings 14 is eliminated in rolling mill bearing Vibration in outer ring 16 avoids rolling mill bearing roller and is squeezed broken, and roll is stuck.Keep the battery pole piece thickness produced uniform Unanimously.

Obviously, the above embodiments are merely examples for clarifying the description, and the restriction not to embodiment.It is right For those skilled in the art, other various forms of variations can also be made on the basis of the above description.Here Without being also impossible to be exhaustive all embodiments.And the obvious variation thus amplified out is still in this reality Among protection scope with novel creation.
