Nail box is the last production process of carton forming. How does the process effect affect the appearance quality of the carton on the one hand and the use performance of the carton on the other hand? From the production process point of view, nail box seems to be a relatively simple process. However, in the daily production, it is inevitable that some quality problems will be exposed. Therefore, the technology and quality control of the nail box process cannot be ignored. Careful control and control must be performed in terms of equipment purchase, operation technology, and material selection. Better prevent or reduce the chance of quality problems.
Nail container equipment recognition and selection principles
With the continuous development of the packaging market, customers in the packaging of products on the appearance of corrugated boxes more and more particular about, in addition to the requirements of uniform ink layout printing, clear print, colorful, in the carton molding also requires the nail saw must be neat, Beautiful. The needs of the market, so that a variety of automatic, semi-automatic nail box machine is also emerging and the user likes. From the various nail box equipments exhibited at the carton equipment exhibition in recent years, its structure is basically similar. However, the use of results is somewhat different. In fact, different styles, different models or even the same model, due to differences in machine performance, structure, manufacturing technology or manufacturing accuracy, the quality of the nail box is also a certain difference. Compared with the manual nail box machine, the automatic and semi-automatic nail box machine not only has high production efficiency, but also has a nail pitch that is uniform and beautiful. The difference between the automatic nail box machine and the semi-automatic nail box machine is that the corrugated cardboard is automatically fed. The paper feeding mechanism folds the cardboard and feeds it into the nail box to carry out the nail box, which can greatly reduce the labor intensity during operation. . The semi-automatic nail box machine is manually folded cardboard and fed into the head nail box, the labor intensity of the operation is relatively large. The semi-automatic nail box machine is generally a horizontal structure and is divided into two types: one-piece and two-piece nail box machines. Among them, the single-piece nail box machine can only be limited to the carton formed by the order sheet, and the two-piece nail box machine structure On the more complex, its function is more complete, both to the carton box can also order two pieces of molded carton. Therefore, in the selection of nail box machine, it must be based on the actual situation of the factory, from the product structure, production characteristics and long-term development trends to consider. In general, long-term products, more fixed specifications of the carton should use high-speed automatic nail box machine; both single and double-shaped carton, it is appropriate to use semi-automatic double-chip nail box machine; if the factory production scale If it is relatively large and the variety is complex, you may consider purchasing several automatic and semi-automatic nail box machines of different types. This will provide more flexibility and complementarity in production scheduling and can better meet production requirements.
The understanding of the characteristics and performance of several styles of nail box machine

Analysis of Common Faults of Stapler Machine
Stiffness or length of the nail has obvious errors
In the nail box, it will be found that when the flat yarn quality is not good, the feed line resistance is large, the feed reel spring is too loose or too tight, the feed reel fixing screw is loosened, the guide rail is deflected, the gear bite is skewed, and the head bottom mold is set When the position of the punch is not correct and the bottom mold has obvious wear, etc., there are prone to the above-mentioned failure phenomenon. In this regard, the solution is: the use of good quality, smooth surface plating of high-quality flat wire; check the various parts of the delivery line is not adjusted and cause jams; adjust the machine-related components to make the wire movement can be easily and comfortably; wear Serious counters take appropriate repair or replacement measures.
The main problem of the heading
When there is a staple in the stapler, it is often easy to affect the normal operation of the clutch. The side cover can be disassembled to take out the punch for cleaning and cleaning, and can be reinstalled after adding the lubricant. If the positioning of the head is not accurate When checking F3 fuses 34-35 (AC), F9 fuses 50-51 (DC), and brake coil resistance wire (15Ω), etc. are normal; if the upper shield photoelectric sensor switch is not activated, the sensor cannot The axis of the guide rail causes the paper not to enter the nail, and the sensing distance of the photoelectric switch can be adjusted. If the nail head has continuous nailing action, it is necessary to check whether the electric appliance is damaged.
Cardboard did not open after the tailgate
If the photoelectric sensor of the baffle is not normal, this fault condition is likely to occur. The photoelectric sensor device can be adjusted so that the sensing distance can be maintained properly to ensure that the paperboard can be normally operated after the baffle plate is fed.
Left and right cardboard feeding belts continue to run after nailing
When the right shutter counts the photoelectric sensing intensity too strong, the above-mentioned troubles are prone to occur. In this regard, the one-shaped knob on the side of the sensor eye can be adjusted, clockwise adjustment can increase the sensing intensity, anti-clockwise adjustment can weaken the sensing intensity, adjusted to normal sensing is appropriate, so that no abnormal situation occurs after nailing.
