Ultra-thin blade machine, with its thin blade, sharp, slitting corrugated cardboard cut smooth without burr, inside, surface paper does not break, corrugated after the cut is not deformed, can perfectly reflect the actual thickness of the cardboard, and equipped with automatic sharpening, automatic The advantages of adjusting knife, line equipment, etc., have been favored by the carton packaging industry.
With the increasingly fierce market competition, the original manufacturers who do not intend to use ultra-thin knife-cutting tools have to make the choice of updating equipment. This undoubtedly creates a good business opportunity for the packaging machinery manufacturing industry. So the ultra-thin blade machines with different styles, different performances and different prices have appeared on the market. Faced with these problems, if we cannot scientifically and rationally purchase products according to our actual needs, and we do not have a complete understanding of the performance of the equipment, then the purchase of an ultra-thin blade machine will not only fail to achieve the desired effect, but it will bring Many troubles come.
Here I will discuss the purchase, use and maintenance of ultra-thin blade machines, as well as the common faults and causes analysis, for peer reference:
First, buy Wants to purchase an ultra-thin blade machine with excellent performance, beautiful appearance, moderate price, strong and durable, and easy operation. We should first understand the type, shape, structure, transmission mode, and paper pressure of the machine on the current market. Line accuracy, effective use of width, degree of automation, grinding wheel, blades, electromagnetic and pneumatic valves and other spare parts are easy to purchase.
The models currently sold in China's ultra-thin blade machines market are either domestically made or imported. They are mainly divided into two types: one is vertical and used with the corrugated cardboard production line; the second is the desktop, which is suitable for independent stand-alone use. The single-waf machine without cardboard line is divided into paper or a small amount of cardboard. They are divided into ordinary type, improved type and high-end computer numerical control. Paper width 1.20 ~ 2.50m; paper accuracy ± 0.2 ~ 1.5mm. 
The so-called ordinary type, whether vertical or desktop, only a set of thin knives and pressure roller, chain drive, supporting power 4 ~ 6kw, manually adjusting knife line. Electromagnetic and pneumatic control grinding knife; improved vertical type for the upper and lower two groups of thin knife, pressure line wheel, and can be freely turned 360 °, knife line wheel can be hydraulically lift, but also manual adjustment, transmission mode for ordinary steel gear transmission. In addition to the common advantages of the desktop, it is also a gear transmission, but the paper feed table, feed positioning baffle slightly longer tens of centimeters, the rear of the paper knife installed guide wheel, avoiding 1î€50m The disadvantages of the above paperboard slitting deflection; In addition to the improved performance of the high-end type, the computer numerical control device is added. As long as the data is input, the adjusting knife line can be automatically completed instantly, and the slitting and pressing accuracy is 0.2-0.5mm. , And with automatic error correction, paper quantitative grinding function (in the paper, as long as the set number of meters, it will automatically grinding the blade, and does not affect the normal production), frequency conversion motor speed saving more convenient, advanced Nylon gears provide ultra-low noise, smooth rotation and no vibration, making them more avant-garde and attractive. In addition to this table there are automatic paper feeding, bilateral positioning device, the paperboard after slitting and pressing lines is more accurate and beautiful; the desktop is also equipped with the linkage of the cardboard line, and the design tends to be perfect.
Ultra-thin knife machine wearing parts: First, thin blades, the specifications are divided into: thickness: 1.2mm ~ 1.3mm, diameter: 245 ~ 300mm, diameter: 105 ~ 175mm range, manufacturing materials due to price differences Differently, the imported blades are the best in Korea, with an effective service life of 5 million meters, followed by Taiwan, with an effective mission life of 1 million meters, and an effective domestic service life of 500-800,000 meters. Common specifications selected 260×158×1.20 are preferred. In addition, it is a sharpening wheel, with gold steel sand as the best. The general model is: 50×15×15×7×2, which is common to various models. The third is the solenoid valve, cylinder, its model specifications are: QB25V-8, pressure 0.7 ~ 0.8Mpa; QCX, bore diameter 41.1 × 25, telescopic range of 30 to 47, the maximum allowable pressure 1.0Mpa (above For general purpose).
After we have learned about the performance, advantages and disadvantages of various ultra-thin blade machines, we will determine the options based on the actual needs of the production, the satisfactory price, and the brand, and then use the following methods to judge the pros and cons:
A. look: beautiful appearance, smooth paint, color depth and uniformity, reasonable and compact structure, the paper guide roller, gear, chain, roller, blade, grinding wheel and other no obvious defects, the machine running smoothly, without jitter .
B. Listen: Start the machine, the sound is normal, no sharp or special metal friction sound, no vibrato.
C. touch: feel the electroplating roller, pressure line, sub-paper knife surface is smooth, work is fine.
D. Test: A corrugated board tester with different material thicknesses can be provided. The machine can be cut in more than 2 meters in a single machine. The skew of the length of the board is no more than 1.5 mm. The knife edge is clean and beautiful, and the normal corrugated board is not deformed.
If you choose the best in this way, we will not be able to buy a satisfiable slim blade machine.
Second, the use and maintenance of use, first carefully check the fasteners are loose, the power valve is leaking, the various operating keys are sensitive, and then add lubricant in the lubrication area, thin knife drive gear coated with high temperature resistant calcium base grease , and then adjust the knife line according to production requirements. Here we must pay attention to adjust the knife distance, the slitting blade should be lifted away from the sipe before moving, and do not interlock with the sipe, otherwise it will easily lead to blade deformation or damage the blade. After the knife position is adjusted, the blade is slowly put into the sipe, the depth is 3~5mm, the blade must be in the center of the sipe, can not be deviated, the two can not contact, otherwise the blade and the s Burned out. The adjustment of the guide roller should be on the same line as the indentation line, and the feed positioning baffle should be fastened and parallel to the side edge of the device. Otherwise, the cut cardboard may be easily deflected, causing extra wheel marks. After everything is in order, confirm the correctness and then manually drive the wheel. If there is no abnormality, turn on the power and turn it on.
The quality of the blade in the production of each 200 ~ 500mm point sharpening once, to maintain the paper-cut incisions and beautiful appearance is appropriate, at the same time pay attention to paper and other foreign objects, not to be involved in the blade drive gear, so as not to damage gears, bearings. After the production is completed, the paper scraps and oil stains on the equipment shall be promptly removed to keep the machine table clean.
After the thin blade machine is used for a period of time, it is necessary to re-tighten the fastening screws. In particular, the screws fixing the blade must be inspected frequently, otherwise the blade may be damaged or the flying blade may hurt. The grinding wheel must also be adjusted in time so that it will be in close contact with the blade when it is sharpened. When the thickness of the grinding wheel is less than 2mm, the new grinding wheel must be replaced. When the outer diameter of the blade is less than 225mm, it must be replaced. The service life of the blades and grinding wheels depends on their quality, the number of papers, and the quality of the paper. When selecting a supplier with good quality and good reputation, it can achieve cost-saving and product-level improvements.
Third, the common fault analysis 1. Start difficult or unable to start 1 lack of voltage; 2 power phase loss; 3 circuit fuse blown; 4 motor has been bad; 5 drive wheel fixed key off; 6 stray foreign objects stuck in the drive gear; The bearing is damaged or the slot clearance is too narrow and the blade is stuck.
