Paper cutters are widely used in life and work, such as paper cutters for household paper, such as paper cutters for toilet paper, and work paper cutters, such as cutting office paper. The working principle and operation of the paper cutter are relatively simple, and the replacement and adjustment of the paper cutter blade need to be paid attention to during use. A good paper cutter can greatly improve the cutting accuracy, so knowing which brand of paper cutter is good is a must-know when purchasing a paper cutter.
1 Introduction of paper cutter
Paper cutter is a traditional product, which is used to deal with the paper cutting requirements in the later stage of printing. From the mechanical paper cutter to the tape-controlled paper cutter, and to the microcomputer program control, color display, full image operation guidance visual processing and computer-aided cutting, the external programming and editing of production data cutting system, making production preparation time. Shorter, more precise cutting, less labor-intensive, and safer to operate.
2 The working principle of the paper cutter
Generally, the paper cutter has an automatic switch system. As long as the old paper is input, the paper cutter will automatically rotate to cut the paper. For some paper cutters, you need to press the start button, the paper cutter will rotate, and you can continue to cut paper. After shredding, press the stop/reverse key to stop the cutter.
3 Cutter purchases
1.Mechanical structure
The paper cutter with double guide rail structure is very troublesome to adjust the accuracy, and the guide rails need to be replaced after wear and tear price is more expensive. The dovetail groove structure of the paper cutter is simple and convenient to adjust the accuracy. Once wear occurs during use, it is only necessary to replace the plug iron.
2. Safety
Is there any anti-fall device on the paper cutter of the paper cutter; Accidental breakage of parts may cause personal injury; whether there is an electronic control system (such as electronic knife lock, etc.) in the running process of the paper cutter to indicate the safety range.
3. Work efficiency and cutting accuracy
The paper feeder of the mechanical paper cutter and hydraulic paper cutter needs to be moved forward and backward. It is controlled by buttons and handwheels. In comparison, the labor intensity of the operator is relatively high and the efficiency is low. The program-controlled paper cutter improves the work efficiency by optimizing the cutting process.
4. After-sale service
A good manufacturer, in the distribution of after-sale service outlets, must consider whether it can make customers in the shortest possible time Obtaining satisfactory service and technical support, and the quality of service before, during and after sale are the concrete manifestations of the comprehensive capabilities of the paper cutter manufacturer.
4 Cutter Operation Rules
1. The operator must be familiar with the performance and safety points of the Cutter, and can operate the Cutter only after passing the test.
2. Before going to work, the operator must wear work clothes, tighten the cuffs, and prohibit long hair, slippers, skirts, and jewelry to operate the machine.
3. Check whether the photoelectric protection switch of the paper cutter is normal and reliable before each startup. First try the empty knife three times, observe whether there is a return knife, if it is found that it is abnormal, it is strictly forbidden to switch, and it can only be used after professional maintenance.
4. Before starting the machine, add lubricating oil with the label to all the lubrication points of the machine. Attention must be paid to the surrounding environment and whether other maintenance work is being carried out on the machine.
5. Check whether the machine is running, the centralized lubrication system, the emergency stop button of each part, and the safety device are normal.
6. It is strictly forbidden to put tools and other objects on the top of the paper cutter (such as steel ruler, wrench, screwdriver)
7. When installing or removing the paper cutter, you should Manual operation is adopted, and the switch can only be turned to the position of the tool change switch after the main motor has completely stopped, and it is strictly forbidden to jog the tool change.
8. When adjusting the depth of the adhesive strip of the paper cutter, the paper cutter should be raised first, and then the depth of the adhesive strip should be carefully adjusted from shallow to deep.
9. After the blade is blunt, the blade should be replaced immediately. Do not continue to use it to avoid overloading the machine and causing damage to the parts.
10. The pressure adjustment of the paper cutter of the paper cutter should not be greater than 60kg/cm2. (Generally around 45 will do).
5 Cutter blade replacement method
When changing the cutter, first turn off the main motor, wait for about 2 minutes, and confirm that the transmission belt has completely stopped running, then replace the two wooden blade changers (provided by the manufacturer) ) under the blade, put the cutting tool selection switch on the switch panel to the tool changing position “”, the tool bed function selection switch must be in the cutting position, use the sleeve to rotate the end face nut of the pulley, and remove all the connecting screws on the blade. Then use the Allen wrench to push the hanging knife device inward about 4MM to disengage the brake of the hanging knife device, rotate the hanging knife device so that the blade can be placed on the two wooden tool changers smoothly, and install the two tool changing handles , remove the blade, and pay attention to hold the blade to prevent overturning and hurting people.
6 Cutter Maintenance and Troubleshooting
Paper Cutter Maintenance
1. Response before the start of work (continue to work after changing shifts or stopping midway) Check the main parts of the paper cutter and add lubricating oil.
2. After each shift, clean the machine once, wipe the exposed friction surface clean and add Jiangyou lubricating oil.
3. Under the normal working condition of two shifts, the machine should be cleaned and inspected every two weeks.
4. If the paper cutter is not used for a long time, all bright surfaces must be wiped clean, coated with anti-rust oil, and covered with a plastic cover to cover the whole machine.
5. If the paper cutter is out of use for more than 3 months, the moisture-proof paper should be covered with anti-rust oil.
6. When checking the disassembly and assembly of the paper cutter, it is forbidden to use inappropriate tools and unreasonable operation methods.
Paper cutter maintenance
1. When semi-automatic, do not step on the foot switch and act immediately.
Most of the reasons for this kind of failure are the damage of the foot switch or the short circuit caused by the water in the foot switch socket, and the other is the problem of the manual start button switch. The repair method is to replace the new switch, socket, push button switch or disassemble and repair related damaged parts.
2. During semi-automatic operation, step on the foot switch slider to descend, and then rise again after releasing it.
This phenomenon is generally caused by the damaged or disconnected connection of the proximity switch on the left side of the horizontal slide. The solution is to replace the proximity switch or connect the switch connection.
3. In semi-automatic operation, step on the foot switch and the vertical sliding seat will descend, and the printing seat will not move after moving to the left.
The reason for this failure is that the proximity switch on the left side of the traverse seat is not sensed or there is a problem. The solution is to adjust the sensing point of the left proximity switch or replace the proximity switch; and the micro switch in the foot switch is stuck and does not work, which will also cause this fault. The solution is to adjust, repair or replace the micro switch inside the foot switch with a new one.
