The use of galvanized or copper-plated low-carbon flat yarns is recommended, and different types of flat yarns are used depending on the size of the carton. Adhesive uses adhesives, and uses different types of adhesives according to the different requirements of carton bonding. Most companies use white latex adhesives. Now some companies use adhesives made of corn starch in order to reduce production costs. Carton box combination, the effect is better.
Cardboard
The paper-laying staff will look for the required paper board in the post-press board placement area or die-cut (cardboard placement area after the press line) according to the production notice; if the paper board is not printed or die-cut (press the thread) in place, the backup staff should go to print Divide the die (cutting line) to understand the situation, and report to the process leader in time so that the plan can be adjusted accordingly;
According to the production notice to obtain cardboard, check the product identification card, the specific content: product name or number, cardboard specifications, layout content. Sampling the first inspection of the cardboard, including: cardboard size, size and pattern of die-cutting or pressing, cardboard color, printing color, warp, quantity, damage, etc., if the number is large, serious problems should be promptly to the process leader. Report, and deal with accordingly;
After correcting, use the forklift to transport the cardboard to the machine. Before transporting, check the height and regularity of the cardboard placed on the wooden frame. If it is too high or not neat, the crew should be requested to cooperate with the transportation. During transportation, collision with other cardboard should be avoided. The pusher is responsible for the stability of the stacking; it is transported to the machine and stacked at the designated position.
Flat tape
Ten minutes before the unit's operation, crew members will issue a picking list according to the production notice to collect from the warehouse. And check the number and quantity of flat yarns. Please note the following common anomalies when checking: Marking and plating, is it a low-carbon flat wire with coating, with or without rust, peeling, cracking, and other defects?
Note: If any of the above conditions occur during production, crew members should record abnormalities and report back to the upper level.
The flats to be used must be placed neatly in the prescribed area, and the number of collars must not exceed the dedicated area.
Debug settings
Put a piece of cardboard at the binding part. The technician sets the staple pressure according to the thickness of the cardboard, and adjusts the width of the nail box support frame according to the length and thickness of the cardboard.
When the thickness of the paperboard is too thick, personnel should be arranged to appropriately thin the folds so that the paper can no longer be crushed;
According to the requirements of the production notice, the box nails shall be nailed along the midline of the overlapping part with a deflection of no more than 3 mm.
The nail pitch is even, the first and last nails are 20mm from the upper and lower lines, the single nail distance is not more than 55mm, and the double nail distance is not more than 75mm.
The process leader and the team leader can each take a cardboard box and carry out the first inspection of the products. When checking, the cartons are placed under natural light. The main items to be noted are as follows:
Nails should be set firmly, set through, no stacking nails, missing nails, upturned nails, broken nails, curved nails, no corners, etc.;

After the box is folded and the box is resting, the difference between the two diagonals of the top surface of the carton with an overall size of less than or equal to 1000 mm shall not be greater than 3 mm, the overall deviation of the inner diameter of the single corrugated box shall not be greater than ±2 mm, and the size of the double corrugated box shall be no more than ±4 mm. The difference between the two diagonals on the top surface of the carton with dimensions greater than 1000mm shall not be greater than 5mm and the overall deviation of the inner diameter of the single-carton carton shall be no more than ±3mm, and the double corrugated carton shall not exceed ±5mm.
Box corner hole diameter is not more than 4mm2, and there must be no obvious wrap angle, outside the flap from the seam or lap joint shall not be greater than 2mm.
Nail boxes should not be subject to inverted nails. Two box blanks with inconsistent yin and yang surfaces, varieties, and specifications must not be misplaced together.
Finally, after the first inspection, the inspection was performed step by step.
The use of nail box equipment needs to pay attention to safety, especially the use of ordinary nail box machine, especially the high-speed nail box face with hand and foot linkage, that is to pay attention to hand, foot and eye coordination, otherwise it is very easy to hurt the hand.
