Nail box production process and its quality control (3)

The left-right paperboard paper feeding belt runs continuously after nailing When the right baffle counts photoelectric induction intensity is too strong, the above-mentioned failures 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.

Differences in the length of the flap after the carton is set

When the cardboard is not positioned at the baffle, the switch is pressed and nailed prematurely; the wear on the upper and lower sides of the toothed belts is too large and the belt clearances on the two sides are too large and inconsistent; the depth of the crates of the carton is not enough, and the carton is folded before the nails and clearly The skewed situation will cause the cartons to be set up, and the lengths of the two sides of the cart cover will be inaccurate. In this regard, the exact cause of the fault must be identified in order to take appropriate measures and correct them.

Inaccurate cardboard pitch

When the left and right side baffles are too tight, so that the resistance is large and the paper feeding is not smooth; the toothed belts obviously wear out, make their heights inconsistent, and the gauge pressure is insufficient, it will easily affect the normal transportation of the paperboard. In this regard, the reasons should be ascertained in order to take appropriate measures to handle and eliminate.

The proper use, maintenance and maintenance of nail box machine

Before using the newly purchased nail box machine, be sure to read the equipment manual carefully to understand the basic structure, performance, and usage of the equipment, and to avoid operational blindness. When nailing the box, adjust the position of the main and left and right baffles and the position of the upper and lower nail heads according to the flaps of the carton. When adjusting, it should be noted that the left and right baffles cannot be clamped too tightly, but the cardboard can be easily inserted and withdrawn. When the mechanical adjustment is completed, you can touch the screen to set the computer: carton height = the original carton height -40mm, the number of carton nails, the carton set distance, whether the set of reinforced nails, single chip, double chip selection and a series of settings, and then Can be nailed box. While paying attention to the correct use of the staple box machine, it is necessary to pay attention to the correct maintenance and maintenance of the machine. This is a key link for improving the production efficiency and the quality of the nail box. It must not be ignored. Therefore, it is required that the head be set and the punch be lubricated once a day; on the fixed shaft of the fixed head and the left and right baffles, the oil should be lubricated and cleaned at any time; the upper and lower nail head drive shafts, the spline shaft, and the drive screw Also need to maintain a good lubrication; down the first easy to flat part of the electroplating crumbs fall off the flattened wire gathered in the punch, usually pay attention to cleaning and cleaning often; after every month to open the head for cleaning and refueling The paper feed belts are equipped with 3 gears on the left and right side plates of the spline shaft, should be filled with butter once a month; the clutch and brake should prevent oil and water from infiltrating; the servo motor should be kept clean to avoid dust accumulation; always to the servo motor The heat-dissipating dust filter of the driver is cleaned; the electrical control box must be kept clean to prevent dust from collecting and causing a short-circuit fault; the inner and outer feed reel shafts should be lubricated with butter to ensure reliable flexibility; and gears and chain requirements for power transmission Lubricate once a month with grease to prevent wear of mechanical parts.

Nail box process technology control essentials

The choice of nail saw

Nail saws should be reasonably selected according to the performance and characteristics of the carton in order to better meet the quality requirements. Nail box saws are divided into three basic forms: oblique nails, straight nails and horizontal nails. The structures include single oblique nails, double oblique nails and reinforced nails; single straight nails, double straight nails and reinforced nails; single horizontal nails and double horizontal nails. And strengthen nails. The form of the nail sawing is usually determined by the structure of the machine. Therefore, the nail box machine must be selected according to the process requirements of the nail box. Generally, the double oblique nails can improve the binding strength of the corrugated box with its arrangement structure, and are generally used. The oblique nails are arranged obliquely in a 45o-like structure. The nail saws of the straight nails are arranged vertically and the nail saws of the horizontal nails are arranged horizontally. A single nail refers to a number of single nail saws at the lap joints of the carton. Double nails are used to set two sets of two sided nail saws. Reinforcement nails are a pair of single nails between two sets of double nails. .
