The paper cutter is mainly composed of a host (also known as a gantry), a workbench, a paper pushing mechanism, a paper pressing mechanism, a cutting mechanism, etc. The paper pushing mechanism is used to push the paper for positioning and post regulation. The paper pressing mechanism presses the paper in place to ensure that the original positioning accuracy is not destroyed during the cutting process. The cutting mechanism is used to cut the paper. Side block gauges, the workbench plays a supporting role. From the driving method of the paper pressing mechanism, it is divided into mechanical paper pressing and hydraulic paper pressing.
        The hydraulic paper pressing method can more accurately ensure the precision of the equal length tolerance of the cut material after cutting (commonly known as the accuracy of the upper and lower knife), especially when the cutting density is larger, the difference is particularly obvious. Therefore, with the advent of hydraulic paper-pressing paper cutters, mechanical paper-pressing paper cutters are no longer used by customers who require high cutting accuracy.
        The clutches of the paper pressing mechanism and the cutting mechanism are driven by hydraulic methods, and are also called full hydraulic or dual hydraulic paper cutting machines. Full hydraulic or dual hydraulic paper cutters have a greater cutting force, which has obvious advantages when cutting high-density cut objects. The clutch is not easy to slip and there is no need to adjust the clutch clearance frequently.
        Dual hydraulic paper cutter adopts microcomputer program control circuit, touch key operation panel, large-screen LCD display, selectable before, after or knife pressure setting, built-in 8 × 9 groups of cutting data memory 6 × 8 components Segment cutting memory, automatic and accurate completion of paper pushing, paper pressing, cutting and other actions. The paper cutter adopts the whole floor type gantry body, dual hydraulic power system, imported main motor and hydraulic valve.

        The performance of the paper cutter is mainly reflected in the cutting accuracy of the paper cutter, accuracy retention, quality stability, ease of operation and safety.
The technical level of the domestic paper cutter has a certain gap with the advanced international countries. The main performances are:
        ① The control system is relatively backward, lacking automatic detection device. In terms of control system, China has just started to use PLC, while foreign countries have adopted full-line computer control, using computer control, using computer to monitor and adjust each execution component, and can be preset The parameters can also be adjusted automatically under the control of the computer, which greatly shortens the auxiliary time and ensures reliable work.
        ②The complete set is poor, and domestic paper cutters are rarely equipped with peripheral equipment, namely: cutting production line.
        ③ There is a certain gap in appearance and ease of use. However, through the efforts of domestic paper cutter manufacturers in recent years, the gap between domestic paper cutters and foreign products is rapidly narrowing, and some technologies are even at the leading level. Foreign ones are basically color microcomputer program control, while domestic ones mainly use digital display. Mainly, a large number of mechanical paper cutters lacking security protection exist and are sold. Microcomputer-controlled paper cutters are the development trend of paper cutters, and are replacing paper with other control methods in a large area with a relatively fast speed.
        After pressing the "Cut" button, the cutter will run up and down more than twice to be called a continuous cutter. The main reason for the continuous knife is that the cutter's cutting knife limit switch fails or does not hit the upper limit switch, and the relay contacts are stuck or sluggish.
        What can not be ignored is the price of the paper cutter, which is an important factor in choosing a domestic paper cutter. Compared with foreign imported paper cutters, it has obvious price advantages, excellent performance, and price concessions are the main reasons for promoting customers to choose domestic paper cutters, and after-sales service in China is relatively in place. Because of its high cost performance and practical and affordable features, the market share of domestic paper cutters is currently the highest in the country.

        Paper cutters are widely used in the papermaking and printing industry, from mechanical paper cutters to tape-controlled paper cutters, to microcomputer program control, color display, full image operation guidance visual processing and computer-aided cutting external programming and The cutting system for editing production data makes the production preparation time shorter, the cutting accuracy is higher, the labor intensity is lower, and the operation is safer. So, what are its advantages, let Xiaobian introduce it to you.
        The cutter's optimized heavy-duty frame design, precision machining, stable performance, and durability; the cutter uses new high-integration and high-stability devices, and the original electronic knife position indicator line to ensure the reliable operation of the cutter; touch key panel, Two-hand interlocking device, automatic reset function to ensure absolute safety. The use of high-speed steel blades is sharp and durable; the unique fault self-detection function makes your operation more handy.
        The above is the advantages of the paper cutter.

        If the cutter blade is not sharp, you need to replace the blade. Today I will introduce how to replace the cutter blade.
        1. Place the blade of the toilet paper cutter at the uppermost position, turn off the machine running switch, cut off the power, and stop the machine. When the machine is stopped, the machine needs to be placed in the cranking state, and the tool bed is stopped in the middle position during cranking. Before replacing the blade, you need to loosen all the screws that fasten the blade on the knife bed, and then insert the tool of the knife into the hexagonal hole on the knife bed, and rotate it counterclockwise, the blade can automatically fall. Put the screw of the knife handle of the tool into the screw hole of the blade, hold the knife handle with your hand, you can take the blade off the hook and put it on the attachment rack, put it in the box to send the grinding.
        2. After removing the blade of the toilet paper cutter, you need to check, check the angle and width of the blade sharpening, wipe the blade with a soft cloth from the back to the blade, then screw the knife wrench into the grinding Or insert the screw hole of the replaced blade into the attachment and push it to the vicinity of the knife bed. The blade is lifted so that the two holes in the middle groove of the blade are hung on the hook extending from the knife bed. Remove the knife handle and install the knife Insert the wrench into the hexagonal hole of the cutter bed and turn it clockwise to automatically raise the blade to a fixed position. Tighten all bolts that secure the blade on the tool bed. The entire process of inserting the blade requires extra care to avoid any hard objects on the blade. Finally, put away all kinds of tools, and the blade fixing work is completed.
        The above is the specific content introduced to you by the editor. The papermaking machine is originally a consumable. Long-term use will cause the loss of machine parts. Therefore, the daily maintenance of the machine is the key to improving the service life of the machine.

        The working principle of the small office paper cutter can be understood as: 1. Light pressure paper 2. Cutting 3. Return of the cutting knife 4. Return of the paper pressure. The following editor specifically said
        From the paper cutter's completion of the above 4 actions, there are 5 steps required:
        ① Lock the cutter at the top dead center position.
        ② Overload protection for cutting resistance.
        ③Two-handed operation, safe, flexible and reliable.
        ④The cutting knife can stop when it moves to any position, and there should be no phenomenon of continuous knife and obvious sliding knife.
        ⑤Operation action can press the paper by foot, single and continuous cutting movement.
        Structure of paper cutter for small office:
        It is mainly composed of host machine, workbench, paper pressing organization, paper pushing organization and cutting organization.
        This paper cutter is mainly used to cut and organize paper before binding many documents, so it is widely used in modern digital quick printing, medium and high-end work, libraries, national government organizations and small and medium-sized printing.
