Printing Table

It is a flat bed structure usually consisting of rectangular or square pieces of segmented blocks. Each segment could be individually level adjusted. Printing bed is covered with Teflon or other smooth materials which scratch proof to glass when it is tr

Air Blower

There is air blower beneath printing bed. There are air holes on printing bed. Air blower creates air cushion on printing bed to float glass while it is traveling. When air blower reverses rotating, it creates vacuum, if necessary, to hold glass firmly in place during printing.

Registration

There are several positioning pins or small blocks in between and lie below level of segmented flat bed pieces. The pins or blocks are distributed in both longitudinal and traverse orientation on printing bed. They are adjustable along channels between segmented flat bed act according to glass size and shape. Pneumatic cylinders are installed beneath printing bed. They are used to push pop up positioning pins along channels until they hold glass in accurate position. Position of each pin is individually adjustable so that it could accommodate to hold almost numerous glass shapes. Height levels of positioning pins are also adjustable.

Convey

There are conveyor belts running longitudinally across printing table. They are in between segmented printing bed and lie below printing bed's level. Belt traveling speed is adjustable.

Stencil Hold

Screen frame is hold and clamped by pneumatic cylinders tightly right above printing table. Thanks to its fast connection design, changeover of stencil is fast and easy. There are adjustable knobs and positioning devices which are used to fine tune until precise position of stencil is obtained. This is useful particularly for multi-colours images. When stencil frame is in precise position, frame is pneumatically clamped.

Bars

Squeegee and flood bars are similar bars usually made of rubber. Squeegee bar is used to press ink onto glass surface through screen mesh. Flood bar recovers ink. Each bar can move up and down by pneumatic. Bar pressure acting on screen is adjustable. While one bar is working at down position, another bar is idle at up position. Inclined angles of bars to stencil are adjustable. There are adjustable handles with gauges to control up and down motion of both bars. Both bars are tightened by special locking system which allows easy loosing and clamping.

Bars Movement

The two bars run transversely above printing table. They are motorized driven through gear reductor with timing belt and high precision linear rack. Squeegee bar moves horizontally to bring and press ink onto glass surface through screen mesh. Flood bar recovers ink back to where it begins by moving back to its original position. Both bars move together. Moving speed is infinitely adjustable according to requirements. Adequate bar travel speed results in high printing quality while long life time of screen. Moving system is consistent to guarantee remarkable printing performance. Stroke length is adjustable according to image printing length.

Stencil Up & Down

Four Columns & Cantilever Structures - Two types of design are available according to printing areas. Four columns structure is for large and medium printing areas. Cantilever structure is for medium small printing areas. Stencil holding system is incorporated to this up and down system. Distance between stencil and glass is adjustable. Vertical movement is achieved by high precision photocell and limit switch. There is a safety system preventing screen from over travel when it reaches at lowest or highest position.

Tilting Structure - It is design for small printing areas. Screen frame holding system is incorporated to this tilting system activated by pneumatic cylinders.

Peel Off

It is used to push and tilt slightly the stencil while squeegee bar is moving. Titling action is synchronized with squeegee bar travel speed with the help of motorized pneumatic cylinder. Better ink printing quality is obtained when stencil is slightly detach and peel off from glass surface while printing. An auxiliary quick return device is equipped. It guarantees ink recover is performed only after screen frame is back to perfect horizontal level when peel off is done. Peel off tilting height is also adjustable.
