A kind of double spread transfer type coating machine
Technical field
The invention belongs to field of batteries, and in particular to a kind of double spread transfer type coating machine.
Background technology
Coating is one of critical process in lithium ion battery production process, and coating machine is in entire Battery Plant's fixed assets
Occupy important proportion.Overwhelming majority factory uses single side transfer type coating machine, technology maturation, equipment to stablize at present, price
Rationally, but due to can only one side coating, so production efficiency is relatively general.
Currently, squash type unicoater has come out, but price is extremely expensive, an import extrusion coater price
It is more than ten times of prices of common domestic single side transfer type coating machine, turns even if domestic two-sided extrusion formula coating machine is also common single side
3-5 times of shifting formula coating machine price.And wherein there is also many technical problems, such as coated face density are unstable, there are
Long-term change trend problem for the more applying the more thin etc..Also extrusion coater mostly uses horizontal drying oven, in order not to allow wet feed to adhere to roller
On son, has and pole piece is lifted to front haulage using air supporting, but this method often pulls apart pole piece, has some limitations.
It is so suitable either with or without price, and the coating machine of energy double-surface-stabilized work, coating machine of the invention can be real
Existing double spread, and performance is stablized, it is cheap, it is promoted the use of suitable for mass production.
Invention content
First, in order to solve the problems, such as that double spread wet feed cannot cross roller, present invention employs special designings, by foil wet
It is vertically drawn high before material is not dry, the two sides of such foil equipment of get along well contacts, then to prevent wet feed from moving down, in baking oven
Hot wind blow material obliquely from two sides, can not only dry in this way, but also wet feed can be prevented to glide.But actual conditions are, such as pulp
Expect modest viscosity, under normal circumstances, the influence that slurry flows downward can be ignored.
Secondly, it is how to realize two-sided while the problem of be coated with, the present invention solves this using special designing coating machine
A problem.Coater head A, B is respectively by holder, fullstop rotor, paint roller, excessively roller, servo motor, guide rail slide block, leading screw, gas
Cylinder, striker plate composition, wherein fullstop rotor adjust the spacing with paint roller by cylinder and guide rail and sliding block above paint roller
From, to play the role of control paint thickness, bottom striker plate and side bumper flitch assembly after with paint roller formed hopper, paint roller rotate after
Wet feed adheres on roller, is coated onto on foil after fullstop knife is scraped and cut, and to form the coating to foil, two head of A, B is placed back to back,
Two paint roller parallel heights are identical, by servo motor(It is omitted in figure)It drives, gap 0-10 millimeters between the two, upper and lower holder
It is connected with servo motor by guide rail, distance can be moved forward and backward by the control upper bracket of servo motor, to control A, B two
The distance between paint roller of head can continuously be coated with or intermittently be coated with, as shown in Figure 1, 2, 3.
In addition, coating machine oven is also special designing, above coater head, baking oven crossed from entrance to top roller it
Between without roller is crossed, have heating system and supply air system among tank wall(It is omitted in figure), foil can be blown by hot wind obliquely, can not only be done
Eliminating dampness material is also prevented from wet feed and flows downward, while baking oven also has Mead-Bauer recovery system(It is omitted in figure), as shown in Figure 4.
The specific technical solution of the present invention is:
A kind of double spread transfer type coating machine, by two transfer type coating machine head A(100)And B(200)It places back-to-back, foil
Material(Copper foil or aluminium foil)(300)From discharging roll(500)It sets out, roller is crossed by coater head bottom(113)It hangs down among from two heads
It is directly pulled up, in baking oven(400)Roller is passed through at top(401、402)Rotary head is downward, using roller(403)Reach receiving volume
(600);When work, A(100)And B(200)Two head paint rollers(107、207)Simultaneously from tow sides to foil(300)Coating,
Then to mobile at the top of baking oven (400), intermediate without roller is crossed before reaching top, baking oven (400) hot wind blows wet feed progress obliquely
It is dry, using baking oven when downlink(400)Heating, finally winding complete;Servo motor (101), leading screw can wherein be passed through
(102), guide rail (103) and sliding block (104) control upper and lower holder(105、106)Between be moved forward and backward distance and control A(100)、
The paint roller of (200) two heads of B(107、207)The distance between realize that continuous coating or interval are coated with.
Preferably, the transfer type coating machine head A(100)And B(200)Respectively by holder(105、106), fullstop knife
(111), paint roller(107、207), cross roller(113), servo motor(101), leading screw(102), guide rail(103), sliding block(104), lead
Rail(108), cylinder(112), striker plate(109、110)With fullstop knife(111)Composition, wherein fullstop knife(111)In paint roller(107)
Top;Pass through cylinder(112), guide rail(108)With sliding block adjusting and paint roller(107)Between distance control the thickness of coating;Bottom
Striker plate(109)With side bumper flitch(110)After assembly with paint roller(107)Form hopper, paint roller(107、207)Wet feed is viscous after rotation
Onto roller, through fullstop knife(111)It scrapes and is coated onto foil after cutting(300)On, it is formed to foil(300)Coating;A, two heads of B(100、
200)It is placed back to back, two paint rollers(107、207)Parallel height is identical, is driven by servo motor, between the two gap 0 ~ 10
Millimeter, upper and lower holder(105、106)Pass through guide rail(103), leading screw(102)And servo motor(101)Connection passes through servo electricity
Machine(101)Control upper bracket(105)Distance is moved forward and backward to control two head of A, B(100、200)Paint roller(107、207)Between
Distance realize that continuous coating or interval are coated with.
Preferably, the baking oven(400)Above coater head, baking oven(400)It is crossed between roller from entrance to top
Without roller is crossed, there are heating system and supply air system among tank wall(It is omitted in figure), foil can be blown by hot wind obliquely(300)It is done
It is dry, wet feed can be not only dried, wet feed is also prevented from and flows downward, while baking oven(400)Also Mead-Bauer recovery system.
Preferably, the course of work of the coating machine is:First by bottom striker plate(109)With side bumper flitch(110)Dress
It prepares and paint roller(107 or 207)Hopper is formed, with leash by foil(300)Material is from discharging roll(500)It is connected to receiving volume
(600), the slurry that will be coated with introduces hopper, opens the heating supply air system and Mead-Bauer recovery system of baking oven, opens equipment
Start to be coated with, two head of A, B(100、200)Paint roller(107、207)Simultaneously from tow sides to foil(300)Coating, it is then wet
Foil is to baking oven(400)Top is moved, baking oven(400)Hot wind blows wet feed obliquely, arrives roller(401、402)When dried it is no longer viscous
Roller crosses foil after roller(300)Downlink again, while baking oven(400)Continue heat drying, finally winding is completed.
The invention has the advantages that the coating function of the present invention has significantly improved production efficiency, the throwing of equipment is reduced
Enter cost, performance is stablized, cheap, is promoted the use of suitable for mass production.
