Description

Diaphragm coating machine and its sided corona treatment unit

Technical field

The utility model is related to protection of film process equipment field, at more particularly to a kind of diaphragm coating machine and its corona Manage unit.

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. CN201244912 Chinese patent discloses a kind of corona treatment plant of cast film machine, it Including organic frame, it is characterised in that be provided with looping casting films and rotatable Corona roller, the Corona roller in frame in frame Be respectively arranged on the left side and the right side that a rotatable left side is cranked arm, the right side is cranked arm, wherein it is any one crank arm it is upper equipped with casting films can be pressed in On Corona roller side face and rotatable pressure roller；Provided with can be to the curtain coating that is wrapped on Corona roller side face on the outside of Corona roller in frame Film outer surface carries out the corona unit of corona；Carry-over pinch rolls and transmission curtain coating that driving casting films are advanced are additionally provided with frame The guide roller of film.

This corona treatment plant is although simple in construction, easy for installation, can sweetly disposition casting films corona surface, but be due to Diaphragm is a roll of coating for carrying out glue, and when changing diaphragm, the inconvenient diaphragm of this corona treatment plant is worn Cross, the operating efficiency of operating personnel can be influenceed.

Utility model content

A purpose of the present utility model is to provide a kind of coating machine corona processing unit, and it, which has, is convenient for changing protection Film, improves the advantage of operating efficiency.

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

A kind of coating machine corona processing unit, including body, the shell that is fixed on body and it is rotatably connected on shell On film guiding roller, the shell includes upper shell and lower house, and film guiding roller is arranged in upper shell, is sent out in lower house provided with corona It is additionally provided with raw device, shell for driving lower house to be adjacent to or keying unit away from upper shell, it includes drive cylinder, connected The drive link of upper shell and lower house.

It is arranged such, diaphragm first passes through film guiding roller before coating glue, now upper shell is closed with lower house, corona Generator carries out sided corona treatment to diaphragm, using high-frequency high voltage in processed frosting corona discharge, makes diaphragm Surface have higher tack, the glue after being so allowed to is easier to be attached to the surface of diaphragm, so as to increase The coating effect of glue, and when needing to change diaphragm, operating personnel can close corona unit and start drive cylinder, Make it drive lower house to be moved away from upper shell, enough operating spaces are reserved to change diaphragm, so as to be convenient for changing protection Film, improves the operating efficiency of operating personnel.

Further set：The drive link includes connecting rod, and connecting rod one end is hinged with upper shell, the other end and lower casing Body is fixed, and is fixed between connecting rod and lower house by two tie points, the output shaft of drive cylinder is hinged on lower house.

It is arranged such, the output elongate axis of drive cylinder, then can drives lower house being hinged around connecting rod and upper shell Point rotation, it becomes possible to reach and open lower house, flows out the purpose of operational controls, and connecting rod is connected with lower house by two Point is fixed, and the connection between them can be made more firm, moreover it is possible to ensure the flip angle of lower house.

Further set：The drive link includes arch connecting rod and auxiliary connecting rod, one end of arch connecting rod and lower house It is hinged, the output shaft of the other end and drive cylinder is hinged, and intermediate position is hinged on body.

It is arranged such, the output shaft of drive cylinder stretches out or withdrawn, and one end of arch connecting rod can be driven, about it The middle pin joint with body rotates, then the other end of arch bar drives lower house rotation, so as to reach lower casing in folding The purpose of body, while aiding in connecting rod arch bar can be helped to play a supporting role lower house, so as to keep lower house Stability.

Further set：The auxiliary connecting rod be arranged in parallel with arch connecting rod, and its two ends is respectively hinged at lower house and machine On body.

It is arranged such, when arch connecting rod drives lower house rotation, auxiliary connecting rod can help the stable lower house of arch connecting rod, Auxiliary connecting rod be arranged in parallel with arch connecting rod can enable it synchronous to a certain extent when rotating, so that lower house is opened Close more stable.

Further set：The drive link includes intersecting being hinged the first actuating arm and the second actuating arm of setting, Two actuating arms are slidably connected with upper shell and lower house respectively.

It is arranged such, two actuating arms are hinged, then the angle changed between actuating arm can just change actuating arm two The distance at end, so as to change the distance between upper shell and lower house, reaches folding shell, is convenient for changing the purpose of diaphragm.

Further set：Drive rod, the other end hinge of drive rod are hinged with two end points of the drive link side It is connected on the output shaft of drive cylinder.

It is arranged such, drive rod is hinged on the side of drive link, the output shaft of drive cylinder promotes drive rod just can Two actuating arm rotations are promoted, change its angle, so as to reach the purpose for changing upper shell and lower house height.

Further set：The drive cylinder and drive link are symmetrical arranged relative to the center line of housing.

It is arranged such, because the length of film guiding roller and shell is longer, sets one group of drive cylinder and drive link can not The stability of whole sided corona treatment unit is kept, therefore the center line setting of its asymmetric housings is increased the steady of whole unit It is qualitative, and fastness when strengthening lower house folding.

Further set：The corona unit is set in cambered surface, and its cambered surface is fitted setting with film guiding roller.

It is arranged such, because film guiding roller is cylindrical shape, diaphragm is by film guiding roller and drives film guiding roller to rotate, by electricity Corona generator is set in cambered surface can make it more suitably be fitted with diaphragm and film guiding roller, so as to strengthen corona unit Effect, and reduce the possibility that corona unit destroys diaphragm.

Another object of the present utility model is to provide a kind of diaphragm coating machine, and it, which has, is convenient for changing diaphragm, carries The advantage of high workload 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, coater unit and drying unit, also with upper State any one coating machine corona processing unit.

In summary, the utility model has the advantages that：

The surface of diaphragm, which can be made, has higher tack, while increasing the coating effect of glue, to change protection Film reserves enough operating spaces, so as to be convenient for changing diaphragm, improves the operating efficiency of operating personnel, additionally it is possible to reduce corona Generator destroys the possibility of diaphragm.
