Outline
Flat sheet cutter is a cutting machine, using a wide range, can be used for paper, leather, plastic, cardboard and other materials cutting. Cutter mainly by the host (also known as the Dragon), table, pushing the paper sector, press the paper sector, cutting agencies and other components. Push the paper push the paper positioning and institutions for the rules for the latter, the pressure will be a good bit of paper organization paper pressed, to ensure that the cutting process does not destroy the original positioning accuracy, cutting agencies to cut the paper side of the baffle for the side of the block rules, table play a supportive role. Printing, packaging, bookbinding and other production expected from the open printing and binding the finished product after the cutting of the hair cutter needs to be cut, so the cutter is the importance of finishing equipment. Flat sheet cutter is widely used in printing, Zhuangding Chang, packing plants, paper products processing plants.
Ping Zhang cutter cutting process
1) According to the paper size is determined the push cut paper for the location; 2) to break Sarkozy has been pushing the paper close to the surface and the side of the paper's front baffle, the paper positioning; 3) press the paper machine paper first pressed down, Then cut the paper cutter and then fall; 4) cutting is completed, the cutter left the stack before return, and then press the paper machine to rise again reset.
Factors affecting the safe use of cutter
Cutter security issues, many practitioners of digital printing easy to overlook the problems that affect the safe use of cutter has the following aspects: 1, brakes. Many manufacturers in order to save money, using the brake circuit theory, that is, through the upper and lower level sensor cut off the cutter motor brake power means, such a device in a sudden power failure, loose sockets, sensor failures and other circumstances, may lead to "slip knife." and other extremely dangerous situation. To prevent this from happening, it is necessary the use of a motor with mechanical brake components, so no matter what circuit fault, the motor is locking, and avoid accidents. 2, two-button operation principle. This requires pressing two buttons simultaneously, otherwise the cutter motor will not move, it can guarantee the absolute safety of single-person operation. 3, in actual use, often with two operations, so the situation becomes very dangerous, which requires the cutter configuration before and after the security cover. When the safety cover is opened, the motor will not move, to ensure safety. 4, these are factors that affect the safety of the process, then the maintenance, care should pay attention to replace the blade, the knife with care to ensure the blade edge is closed, only guarantor of security, but also to ensure that edge is not damaged. 5 Moreover, remove the blade must not arbitrarily set aside, to avoid hurting people. Therefore, we must first choose a high factor of safety equipment, In addition, we must develop good habits, so as to ensure work safety. Edit this section the classification of flat sheet cutter
1 flat sheet of paper cutter body from pushing on the drive is divided into electric paper cutter (only manually press the button or by operating the appropriate agency or mechanical transmission of motor control to push the drawer to achieve positioning), programmable paper cutter (by pushing the paper process control system for automatic positioning device can also perform electric paper cutter positioning means) between the two modes and a range of intelligent digital display paper cutter (by general positioning control system automatically, then manually fine-tuning to achieve accurate positioning). 2, programmable paper cutter paper from the push to control the way mobile devices are divided into stepper motor control, frequency control, AC servo control in three ways. Stepper motor control and inverter control device in the paper cutter to push the positioning accuracy can be achieved ± 0.1mm, speed of 8-14 m / min (specific to the accuracy and speed due to manufacturers using control system and use the different electrical components will be quite different), but the stepper motor control than the harsh noise started, not many manufacturers and paper cutter paper cutter users are optimistic. AC servo control push the drawer of the cutter positioning accuracy and speed than the frequency control with a great breakthrough in quality and quantity, positioning accuracy can reach ± ​​0.025-± 0.015mm, push paper, speed can reach 16-20 m / min (specific to the accuracy and speed of use by manufacturers of control systems and use the different electrical components will be quite different). 3, the user interface from the program-controlled cutting machine (operation) is divided into push-button on the touch screen, buttons and touch screen dual-mode three. Key way cutter first appeared in the program-controlled operation, digital display paper cutter than doubling the efficiency for a large number of users to increase work efficiency, and create more wealth, much the customer pro-gaze, but it came out in the new technology In this way the operation can not be intuitive and easy touch screen operation with the comparable. Touch-screen mode of operation can easily achieve attainment, equidistant, circular dimension, the use of calculators and calculation procedures, the input functions, simple operation (push-button operation to perform certain functions in several key combinations required to operate can be achieved, because many customers can not find replacement operator instructions to the manufacturer after use); screen on the machine to run on various aspects of visual detection switch status display for trouble shooting provided a great convenience for the cutter's customers and manufacturers use to save time and money costs. Dual-mode keys and touch screen, can be used in combination, can meet some of the operators of the old habits, while providing one more input, the durability has relatively increased, but the touch-screen operation cutter manufacturers to design the interface and Actions menu and choose a reasonable screen quality is stable and reliable conditions, its significance is not great. 4, press the paper sector from the drive the way the paper is divided into mechanical pressure and hydraulic pressure paper. Hydraulic paper cutting things way to ensure more accurate cut length tolerances after the other (commonly known as the upper and lower knife precision), especially when cutting material density crop, the difference is particularly evident. Therefore, the hydraulic pressure of the paper with the emergence of the way Cutter, mechanical pressure the way the paper cutter is no longer on the cutting precision high level of customer choice. Platen clutch institutions and agencies are cutting way hydraulic drive also known as hydraulic or dual hydraulic cutter. Dual hydraulic cutter hydraulic or greater cutting force, cutting in cutting high-density material has obvious advantages when the clutch is not easy to slip, and do not frequently adjust the clutch gap. 5, from the size display and push the mobile positioning device on the paper is divided into program-controlled digital display paper cutter and paper cutter (usually on the table purely mechanical cutter embedded ruler, push the paper's control of the digital display Cutter does). Program-controlled digital display paper cutter and paper cutter main difference in the paper pushing agency control, programmable paper cutter has not only greatly improve the efficiency, but also effectively reduce the operator's labor intensity. 6, the width from flat sheet cutter width (maximum cutting width) on the cutter is divided into off (also called half-open cutter), full-cutter (full sheet cutter) etc., many articles have been covered, I will not repeat them. High-end flat sheet cutter not only reflected in the cutting of precision, stability and performance of materials, components and control systems used, etc., in security, there is also multiple protection, embodied in the hands differential protection, optical protection electronic lock knife and so on.
