Description

Diaphragm coating machine and its coater unit

Technical field

The utility model is related to protection of film process equipment field, and more particularly to a kind of diaphragm coating machine and its coating are single Member.

Background technology

Pad pasting mirror, also known as safety mirror or explosion-proof mirror, are that one layer of modeling is pasted at the glass mirror back side with mirror laminator Expect protective film, formula plastic protective film is firmly pasted onto the mirror back side, when mirror is broken, fragment is not sputtered disorderly, and Original place is remained adhered to, so as to avoid injury, such a safety mirror is adapted to make in public domain, ramp gate and interior decoration With.

Need plastic protective film for plastics being attached on minute surface, it is necessary to make it in the one side coating Aqueous Adhesives of plastic protective film for plastics It is attached on minute surface, therefore people complete this work using coating machine.

Coating machine is mainly used in the surface coating process production of film, paper etc., and this machine is that coiled base material is coated into one Wound after glue, coating or ink of layer specific function etc., and drying.

At present, Publication No. CN204725983U Chinese patent discloses a kind of coating machine, and it includes feeding device, applied Cloth apparatus, wrap-up and film covering device, feeding device provide apparatus for coating raw material, apparatus for coating discharging opening and wrap-up phase Connection, wrap-up includes the wind-up roll of the first wind-up roll two and guide roller, and the first wind-up roll and the second wind-up roll are located at respectively leads To the roller left and right sides, the first wind-up roll and the second wind-up roll are alternately connected with guide roller for winding finished product, film covering device bag Include for film frame and pressing frame, including first for film frame supplies deflector roll and second to supply deflector roll, and first provides for deflector roll and second for deflector roll Overlay film raw material, pressing frame provided with pressing roller group, pressing roller group by the semi-finished product of apparatus for coating discharging opening with first supply deflector roll or The overlay film raw material that person second provides for deflector roll is pressed, and guide roller is connected with pressing the discharging opening of roller group.

Although this coating machine can uninterruptedly wind blanking and production band diaphragm, convenient storage finished product is being applied Due to needing to use scraper to strike off glue unnecessary on diaphragm during cloth, so in the diaphragm more renewed, it is not easy to will Diaphragm passes through scraper and applicator roll, and production efficiency is not high.

Utility model content

A purpose of the present utility model is to provide a kind of coating machine coater unit, and it has the replacing for facilitating diaphragm, Improve the advantage of production efficiency.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of coating machine coater unit, including pedestal, the hopper being arranged on pedestal, guide roller, be connected in hopper Applicator roll and scraper, the scraper abutted with applicator roll, and applicator roll is slidably connected on pedestal, and is driven by drive mechanism It is slid, and scraper is rotatably connected on pedestal by bindiny mechanism, and bindiny mechanism includes being fixed on the turning arm at scraper two ends, rotation It is hinged in the middle of pivoted arm with pedestal, the one end of turning arm away from scraper is hinged with connection cylinder.

It is arranged such, when the coating of a roll of diaphragm is finished, operating personnel can start connection cylinder, connect the defeated of cylinder Shaft pushes turning arm, makes it drive scraper overall away from applicator roll around the other end of middle pin joint rotation turning arm, Applicator roll lifting is now made it away from by hopper by the driving of drive mechanism, can so be reserved to operating personnel enough Operating space, is easy to operating personnel that lower a roll of diaphragm is facilitated into operating personnel around being located on applicator roll, so to diaphragm Replacing, largely improve overall operating efficiency.

Further set：The pedestal is provided with the spacer pin for being used for limiting the turning arm anglec of rotation.

It is arranged such, the distance between scraper and applicator roll closely easily make scraper be rubbed on applicator roll excessively, so easy Cause the abrasion of scraper and applicator roll, or even cause the damage of diaphragm, spacer pin is set on pedestal, turning arm drives When scraper rotates, reach after specified location, spacer pin can limit turning arm, make to keep between scraper and applicator roll it is appropriate away from From.

Further set：The pedestal is provided with slide rail, and the two ends of applicator roll are provided with sliding block, and sliding block is embedded in slide rail.

It is arranged such, diaphragm is passed through applicator roll, it is necessary to the lifting from hopper by applicator roll by operating personnel for convenience, And sliding block is embedded in slide rail, sliding block can be slided with the track of slide rail, and the position for lifting applicator roll provides basic bar Part.

Further set：The two ends of the applicator roll are fixed with rolling bearing, and rolling bearing is fixed in sliding block.

Be arranged such, under the drive of diaphragm, applicator roll can rotate on pedestal so that diaphragm by hopper simultaneously And upper glue is coated, the setting of rolling bearing can reduce friction of the applicator roll when rotated between pedestal, and it is fixed on cunning In block applicator roll can be allowed to be slid with the slip of rolling bearing and sliding block.

Further set：Sliding cylinder is fixed with the pedestal, the output shaft of sliding cylinder is fixed on sliding block.

It is arranged such, sliding cylinder promotes its output shaft to push and retract, thus band movable slider slides up and down in slide rail, Reach the effect for changing applicator roll height.

Further set：The guide roller is fixed on sliding block, and its position is constant relative to applicator roll.

It is arranged such, the effect of guide roller is diaphragm positioning and guiding for conveying, and guide roller is crossed in diaphragm winding can So that diaphragm is tightened up, it is set to keep smooth and enter next unit, due to its relative position inconvenience with applicator roll, therefore The tightening state of diaphragm can be kept in lifting applicator roll.

Further set：The scraper includes knife plate and is arranged on the appearance on the sword side at knife plate edge, sword side and applicator roll Face is abutted.

It is arranged such, the effect of scraper there are two, and one is that the glue being more than on diaphragm is blown off, and another is to maintain Diaphragm and the state of being close to of applicator roll, sword side can preferably remove the glue on diaphragm, and can keep diaphragm It is close on applicator roll.

Further set：The sword side is curved to be set, and the outer surface of its shape and applicator roll fits.

It is arranged such, sword side arc sets and fitted with applicator roll outer surface, can be use up when scraper is contacted with diaphragm Amount keeps the complete of diaphragm, prevents scraper from scratching diaphragm, to ensure the quality of product.

Another object of the present utility model is to provide a kind of diaphragm coating machine, and it has the replacing for facilitating diaphragm, Improve the advantage of production efficiency.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of diaphragm coating machine, including feed mechanism, rolling unit, sided corona treatment unit and drying unit, go back band There is any one above-mentioned coating machine coater unit.

In summary, the utility model has the advantages that：

Enough operating spaces can be reserved to operating personnel, are easy to operating personnel by lower a roll of diaphragm around being located at coating On roller, and replacing of the operating personnel to diaphragm is facilitated, largely improve overall operating efficiency.
