Brief Introduction Of Cutting Principle And Cutting Process Of Film Slitting Machine
What is a film slitter?
The film slitting machine can cut: polyester film, aluminized film, BOPP LDPE, HDPE, LLDPE, PP and other films. Mica tape and PE can also be cut into different sizes, which are widely used in packaging and other laminating industries.
The film slitting machine consists of an unwinding mechanism, a cutting mechanism, a winding mechanism, various functional rollers, tension control, deviation correction control and detection devices. Its working principle is: the metallized film raw material released from the unwinding mechanism enters the cutting mechanism through the flattening roller, tension detection roller, empowering roller, and deviation correction system. After the raw material is cut, it is rewound by the winding mechanism into Compliant film rolls.
Film slitting machine working process
Loading: According to the requirements of the slitting plan, according to the driving operation rules, and according to the actual situation, the corresponding parent rolls are hoisted on the aging rack, and placed on the unwinding rack of the slitting machine according to the direction selected from the inside and outside of the corona surface, and controlled by the controller. The button clamps the steel core, leaving the steel core support arm and driving.
Film threading: When there is no film on the film slitter, the film must be threaded; use the film threading device of the slitting machine and the function key to tie one end of the original film to the eye of the film threading chain, and activate the film threading button to make the film It is evenly distributed on each roller along the direction of slitting process.
Splicing film: When there is a film on the slitting machine, when changing roll joints, use the vacuum film splicing table, first start the film splicing table to the working position, manually flatten the film on the first traction roller of the slitting machine and start the upper vacuum pump to suck the film , so that the film is evenly adsorbed on the film splicing table, affix the double-sided tape to cut off the excess film under the tape, flatten the film on the unwinding rack and start the lower vacuum pump to make the film absorb smoothly, and take off the upper paper layer of the tape And flatten the adhesive film, the joints should be neat and wrinkle-free, then turn off the upper and lower vacuum pumps, and open the film splicing table to the non-working position.
Blanking: refers to the operation process of removing materials of a certain shape, quantity or quality from the whole or a whole batch of materials after determining the shape, quantity or quality of the material required for the production of the required film shape or product.
Delishi film slitting machine adopts the upper and lower double air-expanding shafts in the same direction as the center, and the clamping of rewinding and unwinding, as well as the movement of the knife shaft and pressure roller are all pneumatically controlled, and the operation is simple and fast. Single motor frequency conversion drive, synchronous belt drive, stable and reliable operation, low noise; tension control magnetic powder clutch winding, magnetic powder brake unwinding, high tension control precision, fast response, wide adjustable range; unwinding adopts advanced analog photoelectric automatic deviation correction System, with static elimination device, edge blowing device, automatic meter counting for winding. Each function can be configured according to customer requirements.
