Abstract

The utility model relates to a gap eliminating device for a coating roller bearing on a lithium battery coater. The gap eliminating device comprises a coating roller, a coating roller bearing, a gap eliminating bearing as well as a gap eliminating bearing sleeve, wherein coating roller bearing bases are arranged at the two ends of the coating roller; the coating roller bearing bases are fixed on a coating head main wallboard by dowel pins; the coating roller bearing and the gap eliminating bearing sleeve are arranged in the coating roller bearing bases; the gap eliminating bearing is arranged in the gap eliminating bearing sleeve; and gap bearing adjusting screws are arranged on the coating roller bearing bases. The gap eliminating device disclosed by the utility model is simple in structure, can ensure stability of coating thickness, improves product qualification rate, reduces waste of slurry and lowers production cost.

Description

Applicator roll bearing on the lithium battery coating machine inter space device that disappears

Technical field

The utility model relates to a kind of electrodes of lithium-ion batteries production equipment, particularly the inter space device that disappears of the applicator roll bearing on a kind of lithium battery coating machine.

Background technology

Lithium-ion electric pool process is very high to pole piece thickness requirement, applicator roll high-precision bearing used all can have play while producing, in transfer coated process, when back flow roll and applicator roll are close to, because two roll-ins are tight, make the skew of applicator roll high-precision bearing gap, applicator roll position is skew and then, the gap of paint roller and scraper also changes, and causes coating layer thickness to change, and finally affects battery pole piece thickness.New clothes timing high-precision bearing play is little, affects also littlely, with a period of time rear bearing play, can become gradually greatly, causes paint roller skew also increasing, finally has a strong impact on pole piece thickness.

Summary of the invention

The purpose of this utility model is just to provide a kind of simple in structure, easy for operation and can eliminate applicator roll bearing on the lithium battery coating machine of the applicator roll bearing clearance inter space device that disappears.

The technical solution of the utility model is achieved in that the inter space device that disappears of the applicator roll bearing on a kind of lithium battery coating machine, comprise applicator roll, applicator roll bearing, gap bearing and the gap axis bearing sleeve that disappears disappear, at the two ends of applicator roll, be provided with applicator roll bearing block, applicator roll bearing block is fixed on dispense tip main wall plate by alignment pin, in applicator roll bearing block, be provided with applicator roll bearing and the gap axis bearing sleeve that disappears, in the gap axis bearing sleeve that disappears, be provided with the gap bearing that disappears, on applicator roll bearing block, be provided with the gap bearing set screw that disappears.

The utility model has the advantages that: simple in structure, can guarantee the stable of coating layer thickness, improved product percent of pass, reduced the waste of slurry, reduced production cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is that applicator roll bearing block A is to structural representation;

In figure: 1 is applicator roll bearing block, 2 is the gap bearing that disappears, and 3 is the gap axis bearing sleeve that disappears, and 4 is applicator roll bearing, and 5 is applicator roll, and 6 is dispense tip main wall plate, and 7 is the gap bearing set screw that disappears.

The specific embodiment

As shown in Figure 1, 2, applicator roll bearing on a kind of lithium battery coating machine inter space device that disappears, comprise applicator roll 5, applicator roll bearing 4, gap bearing 2 and the gap axis bearing sleeve 3 that disappears disappear, at the two ends of applicator roll 5, be provided with applicator roll bearing block 1, applicator roll bearing block 1 is fixed on dispense tip main wall plate 6 by alignment pin, in applicator roll bearing block 1, be provided with applicator roll bearing 4 and the gap axis bearing sleeve 3 that disappears, in the gap axis bearing sleeve 3 that disappears, be provided with the gap bearing 2 that disappears, on applicator roll bearing block 1, be provided with the gap bearing set screw 7 that disappears.

The applicator roll bearing block 1 use alignment pin at the utility model applicator roll 5 two ends is fixed on dispense tip main wall plate 6, applicator roll bearing 4 and the gap axis bearing sleeve 3 that disappears are housed in applicator roll bearing block 1, in the gap axis that disappears bearing sleeve 3, there is the gap of disappearing bearing 2, applicator roll bearing block 1 is equipped with the gap bearing set screw 7 that disappears, screw position is just over against the gap axis bearing sleeve 3 that disappears, the gap bearing set screw 7 that will disappear is tightened, the gap axis bearing sleeve 3 that disappears to applicator roll 5 is exerted pressure, make applicator roll 5 just produce in advance skew, applicator roll bearing 2 gaps are extruded into the stressed opposite direction of gap bearing set screw 7 that disappears, and this skew is fixed.Can be not curved along with leaving of back flow roll, thus the stable of coating layer thickness guaranteed, improve pole piece thickness and precision.

Claims

1. the inter space device that disappears of the applicator roll bearing on a lithium battery coating machine, comprise applicator roll (5), applicator roll bearing (4), gap bearing (2) and the gap axis bearing sleeve (3) that disappears disappear, it is characterized in that: at the two ends of applicator roll (5), be provided with applicator roll bearing block (1), applicator roll bearing block (1) is fixed on dispense tip main wall plate (6) by alignment pin, in applicator roll bearing block (1), be provided with applicator roll bearing (4) and the gap axis bearing sleeve (3) that disappears, in the gap axis bearing sleeve (3) that disappears, be provided with the gap bearing (2) that disappears, on applicator roll bearing block (1), be provided with the gap bearing set screw (7) that disappears.
