Paper cutting machine development status and market (2)

SQZK series program-controlled paper cutters are equipped with automatic paper pressure valves, so that the paper pressure can be reduced to a minimum without affecting the cutting and will not leave indentations on the soft cutting material. The machine can also be purchased solenoid valve, the valve with the KM large-screen control system to achieve 7 pressure control program. It is especially commendable. Paper cutters with a size of 1150mm or more can be equipped with an automatic side-pointing device. In order to automatically remove the waste edge generated during the cutting process. When this device is turned on, the front plate moves forward. The cut waste edge fell into the waste carton, and then the front plate and rear plate were closed again to ensure that the cutting site was clean and organized.
The paper feeder and screw nut seat of the SOZK series program-controlled paper cutter adopt a mature and rigid connection in the world. When the paper is adjusted, no relative displacement occurs between the two. In addition, Shen Wei Da has also introduced a new solution that uses a single spherical support to replace the double spherical support feeder and the screw nut seat, which increases the support area of ​​the pusher against impact. The impact resistance and stability are improved so that the cutting accuracy can be maintained for a long time. Feida brand cutters are also the first to be equipped with a series of supporting auxiliary machines in domestic paper cutters, such as: lifts, jaws, air cushion worktables. The unloader can be combined with a program control machine with a specification of more than 1150mm to automatically complete the loading and unloading, sorting, handling, stacking, etc. of the paper, and the individual machines can also be combined in any combination.
The QZK2200 program-controlled paper cutting machine developed by Shanghai Shenweida Company is called the “aircraft carrier” in the paper cutting machine. It is the largest paper cutting machine at home and abroad, and it can meet the needs of small-scale paper mills for large-scale production and large-scale packaging and cutting. The double worm gear box mounted on the machine makes it easy to cut. The full-hydraulic paper cutting machine that has just been developed in recent years, that is, pressure paper and paper cutting are hydraulically driven, to make the cutting more stable.
2. The Litong brand paper cutters manufactured by Jiangli Litong Printing Machinery Co., Ltd. produced by Lijiang Litong Co., Ltd. generally adopt the dual-rail integrated grooveless workbench technology to slot the middle of the worktable. The middle guide movement of the paper feeder is changed to that of the entire workbench. The paper feeder uses the guide rails on the two sides of the workbench to improve the rigidity of the workbench, and the displacement after the paper pusher collides with is <0.05mm, and the accuracy is much higher. In industry standards. It can be seen that its anti-impact ability and stability have been greatly improved. The paper feeder adjusting mechanism can adjust the parallelism and verticality respectively, locking and positioning, respectively, without interfering with each other, thus improving the positioning accuracy of the paper feeder.
The hydraulic paper press of the machine adopts a counterweight structure and a quick pressurizing cylinder, so that the pressure is balanced and stable, and adjustment is quick and convenient. The airless electromagnetic clutch used on the clutch mechanism has a large suction and braking force to ensure that the clutch mechanism is always in the best working condition, the cutting force is large, the response is fast, and the braking is rapid. Its transmission system uses advanced double-enveloping worm gear drive.
Litong QZYKD2C series paper cutter adopts GERGEK computer control system, equipped with a 12-inch LCD color touch display, a standard 486 industrial motherboard, and a floppy disk drive. It has programming and graphic functions. It uses advanced frequency conversion technology and operates. Tips and self-diagnosis functions.
The most advanced model of the Litong card cutter is the QZYKC3D series. It adopts the AB programmable logic controller, the international advanced SFT-2 computer control system and the Japanese Mitsubishi AC servo control system, and is equipped with a computer PCMCLA. Memory card, so that no restrictions on the programmable, and has all the computer and mechanical parts of the maintenance of data and operator management capabilities, memory storage time of up to 20 years, can be automatically maintained on the operating system, and is equipped with 10-inch LCD color Touch screen display. The machine's data resolution is 0.01mm, positioning accuracy of ± 0.02mm, with self-diagnosis function, dynamic display, dynamic tracking cutting and operating status.
Litong series paper cutters are all produced according to European CE standards. Hydraulic components (including oil pumps, oil seals), bearings, complete electrical components, motors, and high-speed steel blades are all imported. In addition, it can also use imported photoelectric protection system, also equipped with a paper press and table protection cover.
On the one hand, Zhongjiang Litong Company has adopted reliable advanced electrical and hydraulic components and computer control systems at home and abroad. On the other hand, a number of utility model patents have been adopted, which has resulted in a very high level of cutting machines.
Second, the status quo of foreign paper cutting machines and the development of many of the most advanced foreign paper cutting machine is the most famous Bora Cutter. Warrenberg cutter.
The Polar E-type cutter is a programmable basic model, and the Polar ED cutter is the most advanced model, representing the development direction of the cutter. At Drupa2000 exhibition. Polla not only exhibited its advanced models, but also proposed seven cutting programs (cutting systems) centered on the Polar ED cutter for users to choose. This highly efficient networked cutting system, which consists of a combination of high-speed cutters and auxiliary equipment, will gradually replace single-cutting machines and become the mainstream development direction for cutting equipment in developed countries.
