High-precision, high-speed, Litong brand double rail cutter

According to industry insiders, the cutter is an indispensable cutting device in the printing, packaging, and paper products industries. With the continuous progress and development of the society, people have higher and higher requirements for printing and packaging, and thus have put forward higher requirements for the cutting precision and speed of the paper cutting machine. Through many years of research and experimentation, Litong Company has broken through the traditional production process and designed and manufactured a new generation of high-precision, high-speed paper cutters, the Litong brand double rail cutters.
Litong's new-generation dual-track paper cutter has obtained a number of national patents and has been recognized by the international and domestic printing and packaging machinery industry experts as a major innovative technology for the paper cutting machine manufacturing industry.
One, double rail overall grooveless workbench patented technology (patent number: ZL94236552.6)
Technical features: Solve the world-wide problem of the displacement of the paper pusher after impact, and its accuracy is more than eight times higher than the national industry standard.
A groove is formed in the middle of the traditional cutter table, and the paper feeder is moved back and forth by the middle guide movement mode. During the cutting process, when the paper or other cut goods collide with the pusher, it is easy to cause the pusher to swing left and right, resulting in a displacement tilt. As a result, cutting is not parallel and horns do not affect the cutting accuracy. In the use of the need to often adjust and maintain the pusher, damage and time-consuming. The middle slot makes the workbench weak and easily deformed. The oil stain on the screw can easily contaminate the paper, and small cuts can easily slip out of the middle long groove. The dual rail cutter uses a double rail overall slotless table. The feeder pushes two guide rails on both sides of the workbench to overcome the above shortcomings of traditional cutters and make the pusher resistant. Collision ability and stability are greatly improved. The bench is not slotted, but also makes its structure more rigid. The parallelism and verticality of the paper feeder are separated and adjusted. They do not interfere with each other and maintenance adjustment is very convenient.
Second, the balance of pressure plate patented technology (patent number: ZL98229406.9)
Technical features: The paper pressure balance is stable and stable throughout the stroke, and the foot pressure is constant at any position.
The paper press of the traditional paper cutter adopts a spring type structure. The pressure value of the paper press in the whole stroke is not balanced. In the case of long-term alternating load, the spring is easily fatigued, deformed and loses elasticity, and needs frequent adjustment to replace the spring. It is also very inconvenient. Litong brand double-track paper cutter adopts a new technology of counterweight balance structure. The pressure balance of the paper press is stable during the whole stroke, the pressure value is the same in any position, and the operation is stable and the performance is reliable without adjustment and replace. Took the lead in the country to meet the technical standards required by European standards.
Third, electromagnetic clutch brake device patented technology (patent number: ZL98229405.0)
Technical features: Small size, low energy consumption, large cutting force.
Traditional cutters have the disadvantages of large power consumption and slow response of the clutch, which can not meet the requirements of the international standard that the braking time does not exceed 70 milliseconds. The electromagnetic clutch braking device of Litong brand paper cutter has a strong and constant suction force and braking force, a constant output thrust, and ensures that the clutch mechanism works in the best condition, with minimal wear and tear. In order to achieve low power consumption, large cutting force, fast response, fast braking, and meet the requirements of international standards.
Fourth, pusher adjustment device patented technology (patent number: ZL99241123.8)
Technical features: Completely separate the adjustment mechanism of parallelism and verticality, and solve the problem of adjusting and locking the paper feeder.
The mechanism for adjusting the parallelism and verticality of the traditional paper cutter pusher is the same locking and positioning mechanism. When the parallelism and the verticality are adjusted, they interfere with each other and it is difficult to adjust the lock. Causes the paper feeder to have low positioning accuracy and affects the cutting accuracy. Litong brand paper cutter's paper feeder adjustment mechanism completely separates the parallelism and verticality adjustment mechanism, and adjusts and locks the positioning respectively. They did not interfere with each other and adjustments were very convenient. They solved the problem of adjustment and locking of the paper feeder better. The positioning accuracy of the paper feeder has been greatly improved, so that the cutting accuracy of the paper cutting machine has been further improved.
Fifth, advanced linear guide and ball screw Cutter pusher back and forth movement is through the screw drive. The paper feeder of the traditional paper cutter is driven by the silk mother sliding directly on the screw rod, and the silk mother sleeve and the screw rod belong to the plane sliding friction, and the noise is large and the wear is also great. The Litong brand double-track paper cutter adopts the ball screw and linear guide rail with the international advanced level of the 1990s. Both the screw rod and the guide rail are bearing steel ball rolling, and the variable sliding friction is rolling friction. The friction is reduced and the noise is reduced, so that the paper feeder runs smoothly and quickly, positioning is accurate, the precision and speed of the cutting of the machine are greatly improved, and the service life of the machine is prolonged.
VI. Advanced Drive System The Litong brand double-track paper cutter adopts the advanced double-enveloping worm and worm transmission system in the 1990s. It features smooth running, wear-resisting, long service life, high transmission efficiency and energy saving.
VII. Multiple safety protection devices The Litong brand double rail cutters use multiple protection devices such as safety latches, cutter bar overload, electrical overload, infrared grating photoelectric protection, and two-hand differential buttons to ensure the safety of machines and operators. safety standard.
8. New dual-display technology The Litong brand dual-rail digital display cutter adopts a new dual-digital display technology, which is not available in traditional digital cutters. The double digital display technology is characterized by the fact that when the cutter is in operation, both the front and rear dimensions of the cutter are displayed. The size of the knife shows the size the knife will cut, and the size of the knife shows the remaining size. After each cut, the size of the knife is automatically cleared to zero, without disturbing the size of the next knife. Double digital display direct reading, without calculation, at a glance, very convenient, but also improve the cutting efficiency.
9. New computer programmed new technology QZYK C series program controlled paper cutting machine adopts standard type computer, automatic monitoring of positioning, cutting, safety protection, etc., and self fault diagnosis function and operation mode display, can be programmed 100 programs, 3300 More than one different position cutting size QZYK D series program-controlled paper cutting machine with GERGEK system six plus type computer, using AC frequency conversion speed control technology, in addition to positioning, cutting, operation tips, self-diagnosis functions, the user can also be based on The precision required for the cutting product is to select the running speed and positioning accuracy of the paper feeder, programmable 999 pieces, and cutting sizes of 10000 different positions.
QZYW series program-controlled paper cutter uses GERGEK IMAGE control system, equipped with a standard 486 industrial motherboard, 12-inch LCD touch color display, equipped with a floppy disk drive, so that the number of programs without restrictions, and can be directly used by computer programming, in addition to positioning , cutting, operation tips, self-diagnosis functions, and has a graphical illustration and operator management and maintenance functions.
