When it comes to the maintenance of the paper slitter, many people find it very simple, but in fact it is not. If you do not pay attention to some details during the maintenance process, more serious consequences will occur.
1. Pay attention to safety. Never put your hands on the blade when the machine is turning.
2. Grease the lubrication holes regularly. This can reduce the wear of the rotating shaft.
3. The power supply should be safely grounded to ensure no leakage.
4. When the rod nylon washer needs to be used for a long time, if the cutting burr is seriously damaged, it should stop working immediately, open it next to the cover, loosen the nut with a special wrench, loosen the screw, and remove the swing rod.
How is the development of automatic slitting machine in China? What will the present and future look like?
1. Automation control part: At present, the level of automation of the slitter produced in China is still at the lower middle level. Although the use of domestic control original devices has been very popular and the price is relatively low, the depth of use of domestic slitter manufacturers Far behind the level of foreign developed countries, especially in the control system and the structure of the cutting machine and the lack of organic combination of the material cut.
At this level, the overwhelming majority of domestic slitting machines still stay on thick lines, and have not yet deeply understood the rigor and rationality of the slitting machine control system. Domestic slitting machine manufacturers should proceed from the above directions to find a method that conforms to the principle of slitting machine control and can maximize the use of the functions provided by the hardware.
2. Frame structure: Whether it is one-time slitting or two or three-time slitting, domestic slitting machine manufacturers should devote their energy to research on the frame structure, and focus on the slitting machine manufacturers to design a more reasonable slitting machine , Research and design a personalized slitting machine, which makes the structure of slitting different materials more detailed. In the next round of competition in the international market, it will provide a favorable weapon for film-making enterprises, and at the same time find a blue ocean for their own enterprises .
3. Manufacturing: This is a common problem faced by China's manufacturing industry. In addition to being reasonable in design, any mechanical equipment also requires precision in manufacturing, and China's manufacturing industry is lacking in this regard.
The above is the analysis of the development of the automatic cutting machine from three aspects.
At present, the development speed of domestic paper slitting machines is still very fast, but there is still a certain gap with advanced international countries. So what is the gap between domestic and foreign paper slitting machines?
1. Poor completeness, domestic paper cutters are rarely equipped with peripheral equipment, namely: cutting production line.
2. The control system is relatively backward and lacks automatic detection devices. In terms of the control system, China has just started to use PLC, and foreign countries have adopted full-line computer control, using computer control, using the computer to monitor and adjust each execution component, and can predict Set parameters, automatic adjustment under the control of computer, greatly shorten the auxiliary time and ensure reliable work.
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.
4. In terms of price, 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.
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.
