Description
Technical field
The invention belongs to the manufacture field of lithium battery diaphragm, tension force is reduced when being specially a kind of coating for lithium battery diaphragm
Device.
Background technology
At present, as lithium battery enterprise one after another focuses on sight in the use safety of lithium battery, barrier film coating is modified to be made
Barrier film thermal contraction, enhancing barrier film heat endurance can be improved to be a kind of, while improving the surface tension of barrier film, raising barrier film and pole piece
The effective means of cohesive force, very big application has been obtained in barrier film manufacture field.But the lithium ion battery of commercialization at present
Barrier film is influenceed based on polyolefin (PP, PE) barrier film by itself characteristic, and tension force should not be too during post-production for barrier film
Greatly, otherwise the change of its later stage is serious, causes its finished product recovery rate low, so as to add manufacturing cost.
The present invention is by a kind of simple flange fixing installation, each section of running tension when being effectively reduced barrier film coating, while
Can play the spreading to barrier film, reduction barrier film in coating procedure when hightension is run caused by irrecoverability shape
Become, so as to improve the coating quality of barrier film, reduction barrier film is scrapped caused by the later stage changes, the finished product of increase coating barrier film is received
Rate, for traditional pressure roller, the present apparatus is only pressed in the both sides of barrier film, does not result in barrier film wrinkling, contrasts scissors roller, this
Barrier film is pressed on carry-over pinch rolls or deflector roll by device, it is easier to wear film.
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, there is provided the device that a kind of coating of barrier film reduces tension force.
The present invention is achieved by the following technical solutions：
A kind of barrier film coating reduces the device of tension force, including pinch roller, master link, secondary connecting rod, spring, fixing device；
The pinch roller is rotated with master link by secondary connecting rod and is connected；The two ends of the spring be respectively fixedly connected with master link and
In secondary connecting rod；One end of master link is slidably connected with fixing device and is provided with retention mechanism, and the other end is pressed in by pinch roller
Cover on septate roller, fixing device is also fixed and connected with the connecting shaft of deflector roll or the equipment pedestal on drive roll roller both sides
Connect.
In barrier film coating procedure, the both sides of barrier film are pressed on drive roll or deflector roll by pinch roller, and can be transported with barrier film
Go and roll, be fixed in using fixing device in equipment, when barrier film is run, pinch roller can play a part of deckle,
The spreading to barrier film can be played, several groups of devices can be installed more, further reduce barrier film according to the transport stroke of barrier film
Transport tension force.
Preferably, the master link and time connecting rod are connected by rotating shaft.
Preferably, the retention mechanism is jackscrew, and master link retractable adjusts master link by jackscrew
Length.
Preferably, the material of the pinch roller is polyurethane or rubber.
Preferably, the length of the pinch roller is 30~60mm, and the diameter of pinch roller is less than the diameter of roller.
Preferably, a diameter of 30~80mm of the pinch roller.
Preferably, the master link and time connecting rod are stainless steel.
Preferably, the pinch roller more should be arranged on drive roll and the longer deflector roll of barrier film suspension stroke；The dress
Put to use in pairs, use respectively on the both sides of roller；Pinch roller is as scissors roller, it is possible to use spring is lifted and put down, just
In wearing film；The fixing device should be arranged in equipment, be driven pulley；The spring answers length smaller and forms larger,
Make the present apparatus when in use, spring is former length or elongation state, recovers the elastic force that deformation is produced by spring, by the both sides of barrier film
It is pressed on roller, so as to reach flattening and reduce the effect that barrier film transports tension force.
The beneficial effects of the present invention are：
(1) present apparatus is installed and simple to operate, and using simply efficiently, tension force reduces effect substantially, and reduction barrier film is being coated
During when hightension is run caused by irrecoverability deformation, so as to improve the coating quality of barrier film, reduction barrier film is because after
Scrapped caused by phase change, the finished product recovery rate of increase coating barrier film；
(2) present apparatus can play spreading, be equal to scissors roller, but be easier to wear film than scissors roller；
(3) present apparatus is only pressed in the both sides of barrier film, and the quality of medial septum will not be impacted, and in following process every
Film both sides can be cut off, and will not reduce product yield；
(4) present apparatus structure design is flexibly simple, the equipment for making film to needing reduction tension force, there is same effectiveness.
