Nail box production process and its quality control (4)

In general, a single-layer, 3-layered, small carton requires only a few staples to be sufficient to ensure the packaging strength of the carton. The 5th and 7th-floor medium and large-sized cartons can be used to determine the number of double-nails, or double-nail nails, according to the characteristics of the contents, as a starting point for saving both material and nail box strength. Scientifically and reasonably determining the structure of the box nail is the basic principle of the technology control of the nail box.
Box nail quality control

The arrangement and control of the box nails are not only related to the appearance quality of the carton products, but also directly affect the packaging performance of the carton. Therefore, the box nails should be firm, and the nails should be neat and beautiful. The nail saws cannot be stacked nails, stud nails, missing nails or nails. Defects such as obvious deflection of foot shape. Determining the nail pitch of the carton nail saw is an important technical control link in production. The nail box nail box with positioning mechanism is the reliable guarantee for ensuring the nail pitch accurately. According to the relevant standards of corrugated boxes, nail distances must be arranged neatly and uniformly, and the distance between double nails should not exceed 75mm. The distance between single nails should not exceed 55mm, and the distance between head and tail nails should be 13±. For 7mm, the saw must be fully nailed to the lap tongue. The national standard is a guiding standard and is the guiding reference for industrial production reference. However, the customer and the carton factory can also determine the appropriate nail saw according to the characteristics of the carton product to meet the requirements of the product and the province As a guideline, both parties can accept it.

Flat wire quality requirements and technical control

The surface coating of flat yarns is generally made of copper plating and zinc plating. From the perspective of quality and technology, flat yarns are not allowed to have quality defects such as cracks, rust, peeling, bending or uneven thickness. Some of the flat wires are poor in moisture resistance and oxidation resistance, and they are found out from the warehouse and found that rust has not yet been used. If the storage environment is wet, rusting is more likely to occur. Therefore, when purchasing, pay attention to the flat wire with good plating, good rigidity, and elasticity. The uniformity of the thickness and width can be checked with a vernier caliper.

The correct choice of flat yarn

The quality of the flat yarn depends mainly on the raw material properties and the production process. If the flat wire material is not qualified, the quality of the coating will fall off, the feed line will not be smooth, the broken nails, and the nail saw will not be well formed. A good quality flat yarn should have uniform plating, bright, non-bending wire material, soft and moderate steel and elasticity. According to the machine structure of the nail box machine, the flat yarn is determined to use the specifications of the flat yarn, and it is necessary to pay attention to the selection of high quality flat yarn. This is the basis for improving the quality of the nail box and improving the service life of the equipment. The annealing degree of the flat iron wire is about 400 degrees and the time is only 4 hours, while the annealing temperature of the copper plating flat wire is about 900 degrees, the time is 14 hours, and its hardness is about 2 times smaller than the former. The wear of the head parts is better reduced. Therefore, from the perspective of improving the life of the equipment, the selection of copper-plated flat wires is of certain significance.

Nail box production should pay attention to matters

When the foot nail box is used, the hands and feet must be well-matched and carefully operated. If there is no stoppage, do not put your hand into the machine to order the head or other rotating parts to avoid inadvertently injuring your hands. After replacing the new flat yarn, it is necessary to pay attention to lock the flat yarn tray to prevent it from being damaged or hurt. The machine must be properly used, maintained, and lubricated in accordance with the instructions. It must not use inferior flat yarns for the sake of cheapness, but must choose flat yarns that conform to the specifications of the machine.

The correct storage of flat yarn

The wire of the flat wire is an iron wire. Although the surface has a certain anti-oxidation and anti-rust plating, it can easily be rusted if it is not well-kept. Therefore, the flat yarn that has not been used up after opening should be sealed and stored in a moisture-proof manner. Storehouses for flats must have basic requirements for ventilation, drying, non-corrosive and oxidizing substances, and they must not be placed directly on the floor, but should be placed on wooden pallets with a foot height greater than 15cm. To prevent moisture from rusting.

The production efficiency and quality control of the nail box involve many aspects such as equipment performance, technical operation, and the selection and storage of materials. Therefore, as long as the nail box equipment is reasonably selected according to the characteristics of the production, the nail box technology and operation technology are seriously taken into consideration. Off, the use of high-quality flat wire nail boxes, and pay attention to the scientific custody of the flat wire, not only can make the best use of the capacity of the nail box equipment, and the quality of the nail box can also be better guaranteed.
