If the slitting machine is not properly managed, it will become a mess and even cause serious losses. So how does the slitting machine manufacturer manage well.
1. Post staff should pay attention to the cutting quality of the product, check the width, roll length and other indicators, and fill out various quality records as required.
2. The operator must be familiar with the performance of the machine and carry out production operations in strict accordance with the method specified in the equipment manual. To keep the cutting machine clean and tidy, it is strictly prohibited to place tools or supplies on the machine.
3. During the work, pay attention to observe the running state of the unwinding cloth roll. If the system does not have the function of “automatic slowdown and stop in advance”, the speed of the cloth rolls should be reduced and stopped before the cloth rolls are completely exhausted.
4. Only after confirming that the personnel and equipment are in a safe state, can the cutting machine be started, the acceleration process should be stable, and the operators and post personnel must communicate and coordinate with each other.
5. The cutting knife must be installed or replaced only after the machine stops rotating and the power is turned off. When adjusting the position of the slitting knife during operation, someone is required to monitor on the operating table. The replacement cutting tools should be collected and stored centrally and placed at the designated location.
6. During the operation of the slitting machine, the post staff should keep on-site to monitor and manage the equipment. When encountering dangerous situations, emergency measures should be taken in time to stop the operation of the machine and prevent accidents.
7. During the operation of the slitter, it is forbidden to work in the "biting" area, and personnel should avoid the position where the blade is broken and thrown out. While the cloth roll is still rotating, it is forbidden to directly touch the product in motion with hands or tools to check the cutting quality of the cloth roll.
8. Reasonably set and adjust various operating parameters to improve the cutting quality, and the adjustment process should be carried out smoothly. Do not use curved winding rods or eccentric parent rolls with out-of-round shape. The running speed should avoid the resonance area of the device.
9. The unwinding cloth roll should be placed in the specified direction and position, and reliable positioning measures should be provided to prevent the axial movement and radial runout of the cloth roll.
10. When pushing or unloading the product roll, the operator should pay attention to avoid the movement track and area of the movement mechanism to prevent collision or mechanical injury. In the process of unwinding, it is necessary to operate at both ends or outside to make the finished product unload smoothly.
11. Proper use and storage of various measuring instruments; correct operation and use of supporting lifting, transportation, loading and unloading facilities.
The blade of a paper slitter is easily damaged under long-term high-pressure work. Let's take a look at the cause of the blade damage of the paper slitter.
The damage of the slitter blade is the same as the wear of the slitter blade, which is also a form of failure of the slitter blade. When the cutting machine blade is used under certain cutting conditions, if it cannot withstand strong stress (cutting force or thermal stress), sudden damage may occur, causing the tool to lose its cutting ability in advance. This situation is called cutting. The machine blade is damaged. Damage is relative to wear.
In a sense, damage can be considered an abnormal wear. There are two types of damage to the blade of the slitter: early and late (breakage after processing to a certain time). There are two types of damage to the blade of the slitter: brittle damage and plastic damage. When cutting hard alloy and ceramic cutting machine blades, under the action of mechanical and thermal shock, brittle damage often occurs. Brittle damage is further divided into: chipping, breaking, peeling, and crack damage.
The form of blade damage of the slitter is mainly wear and tear. In the modern production system (such as FMS, CIMS, etc.), when the blade of the slitter is abnormally worn or damaged, if it cannot be found and taken measures in time, the workpiece will be scrapped, or even the machine tool will be damaged, causing great losses. Therefore, it is very important to monitor the blade status of the slitter.
The use and installation of the paper slitter need to pay attention to many problems. Let's take a look at the slitter manufacturer.
Introduction to the installation and use adjustment of the paper computer slitter. After unpacking the machine, you should check the integrity of the machine and check whether there is damage during transportation. After checking the damage, you can install the calibration level on a flat and solid basis. , Check whether the parts are intact and intact, whether the connecting bolts are tightened reliably, and whether the moving parts are flexible. Then fill the lubricating parts with the corresponding lubricating oil. After checking the refueling, confirm that they can be turned on before reading. The attached manual. Run slowly at first when starting. After everything is normal, slowly increase the cutting speed until it reaches normal.
High-speed slitting machines are currently used very frequently in industry. Let's take a look at the main features and defects of high-speed slitting machines.
The main feature of the high-speed cutting machine is that the magnetic powder clutch is installed as a resistance. After system control, a DC voltage is output to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive installation that can control less tension. The main drawback is that the speed cannot be high, and high-speed friction of magnetic powder is easily formed during high-speed operation, which generates high temperature, which causes the magnetic powder clutch to generate heat and shorten its life. Use a knife to cut the roll of a certain width longitudinally and cut it into several narrower rolls for installation.
With the development of economy, the slitting machine has also been greatly developed. Various slitting machines have been developed. For example, there are paper slitting machines, automatic slitting machines, and high-speed slitting machines. The emergence of these slitters is a boon.
The slitting machine is a pre-press and post-press equipment that cuts a large roll of paper, film, non-woven fabric, aluminum foil, mica tape and other thin materials into small rolls of different widths. It is commonly used in papermaking machinery and printing and packaging machinery.
In the past, the speed of the magnetic powder clutch of the slitting machine could not be high, because it was easy to cause high-speed friction of the magnetic powder during operation, resulting in high temperatures and shortened its life. Seriously affected the production efficiency. It is now controlled by a dual-frequency motor, so that when the diameter of the rewinding material becomes larger, the frequency-friction motor is controlled to make the magnetic powder friction at a certain value. Without high temperature.
