Here are the detailed steps for maintaining and service the Cardboard Slitting Machine:
1. Cleaning
External cleaning: After each use, use a clean soft cloth to wipe the external surface of the machine, including the machine body, operation panel and bracket. This can remove dust, paper scraps and other impurities that may have accumulated. For the feed and discharge ports of the machine, these areas are prone to accumulate more debris, so they should be cleaned up. You can use a small vacuum cleaner or a soft brush to carefully clean these areas to prevent debris from entering the mechanical structure inside the machine.
Internal cleaning (periodic): Every once in a while (for example, once a week), open the protective cover of the machine (while ensuring that the power is safely turned off) and clean the dust and paper scraps inside. Especially the areas around the motor, drive belt and cutter, where the accumulation of impurities may affect the normal operation of the machine. You can use a compressed air can or a hair dryer (set to the cold wind gear) to blow away dust and small debris.
2. Lubrication
Determine the lubrication points: Find the key lubrication points of the machine, which usually include moving parts such as bearings, chains, gears and guides. These parts will generate friction during operation, and proper lubrication can reduce wear and extend service life.
Choose the right lubricant: Choose a suitable lubricant according to the machine's instruction manual. Generally speaking, grease can be used for bearings that rotate at high speeds; lubricating oil may be required for chains and gears. For example, for machines running in high temperature environments, high temperature resistant lubricants should be used.
Regular lubrication operation: Lubricate according to a certain period (such as daily or weekly, depending on the frequency of use of the machine). Apply or inject lubricant to the lubrication point in an appropriate amount, and be careful not to overdo it to avoid splashing the lubricant on other parts, especially not contaminating the tool and cardboard.
3. Check the tightness of the parts
Visual inspection: Before starting the machine every day, perform a simple visual inspection of the various parts of the machine. Check whether the screws, nuts and bolts show signs of looseness, especially the connection parts of the tool fixture, motor mount and transmission parts. If any parts appear to be loose, further inspection is required.
Manual inspection (if necessary): For screws in key parts, manual inspection can be performed with appropriate tools (such as wrenches), but do not tighten them too hard to avoid damaging the threads. If the screws feel loose, tighten them according to the specified torque.
1. Tool maintenance
Check tool wear: Check the wear of the tool regularly (for example, once a month). You can make a preliminary judgment by observing the edge quality of the cardboard after slitting. If the edge of the cardboard has burrs, unevenness or signs of tearing, it is likely that the tool has been worn. For rotary tools, you can also use tools such as calipers to measure the diameter of the tool and compare it with the original size to determine the amount of wear.
Tool grinding or replacement: When the tool has a certain degree of wear, decide whether to grind or replace it according to the wear. If the wear is light, you can use professional tool grinding equipment to grind and restore the sharpness of the tool. However, if the tool is severely worn, such as obvious notches on the blade or wear exceeds the specified limit (this limit is usually specified by the machine manufacturer), the tool needs to be replaced in time. When replacing the tool, strictly follow the machine's operating manual to ensure that the tool is installed correctly and tighten the tool fixture.
2. Electrical system inspection
Line inspection: Check whether the machine's electrical circuit is damaged, aged or loose. Check whether the insulation layer of the wire has cracks, wear or exposed wire parts. Pay special attention to the joints of the wires to ensure that the joints are firm and there is no looseness or oxidation. If there is a problem with the line, the wire should be repaired or replaced in time.
Electrical component inspection: Check the electrical components such as motors, sensors, and controllers. Check whether the running sound of the motor is normal and whether there is overheating. For sensors, check whether their functions are normal, such as whether the feed sensor can accurately detect the feeding of cardboard, whether the discharge sensor can correctly count the number of cardboards after slitting, etc. For controllers, check whether its display screen is displayed normally, whether various parameter settings can be correctly saved and read, etc. Professional electrical testing tools (such as multimeters) can be used to assist in the inspection.
3. Transmission system inspection
Belt and chain inspection: Check the tension and wear of the transmission belt and chain. If the belt or chain is too loose, it will cause poor power transmission and slippage; if it is too tight, it will increase the wear of the components. Belts and chains that are severely worn (such as cracks in the belt, elongated or worn links of the chain) should be replaced in time.
Gear inspection: Check whether the gear surface is worn, pitted or broken. If the gear is found to have problems, it needs to be replaced in time to avoid affecting the transmission accuracy and stability of the machine. At the same time, check whether the lubricating oil in the gearbox is sufficient and whether it needs to be replaced (generally determined according to the use time and working environment of the machine).
1. Comprehensive disassembly inspection (if possible): If conditions permit, the machine can be fully disassembled and inspected every year. This includes disassembling the main components of the machine (such as the transmission system, cutting system, etc.) for thorough cleaning and inspection. During the disassembly process, pay attention to record the position and installation method of each component so that it can be installed correctly when reassembled.
2. Calibration and precision adjustment: Use professional measuring tools to calibrate the slitting accuracy of the machine. For example, by adjusting the position of the tool, the speed and tension of the feeding system and other parameters, the machine can accurately slit the cardboard according to the set size. The slitting accuracy can be adjusted to the best state according to the technical parameters of the machine and the actual use requirements.
3. Component replacement and upgrade (if necessary): Consider replacing some key components or upgrading the machine according to the wear and tear of the machine and technological development. For example, replacing a motor with a better performance, a more accurate sensor, or adopting a new control system to improve the efficiency and performance of the machine.
