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.
The following author's purchase points for ultra-thin blade machines are provided for peer reference:
To purchase an ultra-thin blade machine with excellent performance, elegant appearance, moderate price, robustness, and easy operation, we must first understand the type, shape, structure, transmission method, accuracy of paper separation, and effectiveness of the machine currently on the market. Whether the use of width, degree of automation, grinding knife wheel, blades, electromagnetic 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 sharpening knife; improved vertical type is composed of upper and lower two groups of thin knife and pressure reel, and can be turned freely 360°. The thin knife and pressure reel can be hydraulically lifted and lowered, and can also be manually adjusted. The transmission mode is common cast steel gear. transmission. In addition to the common advantages of the desktop, it is also a gear drive, but its paper feed table, feed positioning baffle slightly longer tens of centimeters, the rear of the paper knife installed guide wheel, to avoid the 1500mm above cardboard The disadvantages of 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 instantaneously, and the cutting and pressing accuracy is 0.2-0.5mm, and it has automatic correction. Wrong, quantitative paper cutting function (separate paper, as long as the number of meters is reached, the blade will be automatically polished, and does not affect the normal production), the frequency conversion speed motor saves electricity more convenient, advanced nylon gear drive ultra-low Noise, smooth rotation, no vibration, even more avant-garde and attractive charm. 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, outer diameter: 245 ~ 300mm, diameter: 105 ~ 175mm range, manufacturing materials due to different price differences, 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. Third, the solenoid valve, cylinder, its model specifications are: QB25v-8, pressure 0.7 ~ 0.8Mpa; QCX, bore diameter 4.1. × 25, telescopic range of 30 to 47, allowing the maximum pressure of 1.0Mpa (more than a universal type).
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.
Slim knife cutting line machine purchase points
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.
