debugging
Set up
Put a piece of cardboard in the binding section by a technician to set the printing pressure according to the thickness of the cardboard, and adjust the width of the nail box support frame according to the length and thickness of the cardboard;
When the thickness of the cardboard is too thick, personnel should be arranged to properly thin the binding site so that the tissue will not be crushed when binding;
According to the requirements of the production notice, the box nails should be along the center line of the overlapping part and the deflection should not exceed 3mm.
The nail distance is uniform, the distance between the first and tail nails is 20mm above and below the line, the single nail distance is not greater than 55mm, and the double nail distance is not greater than 75mm.
The process leader and squad leader can each take a carton to conduct the first inspection of the product. When checking, put the carton under natural light. The main items to be noted are as follows:
The nails should be fastened and fixed, and there should be no overlapping nails, missing nails, nails, broken nails, bent nails, no corners, etc .;
When stapling the box, the two pieces of box blanks should be aligned, and there should be no scissors mouth;
The folded box should be squared after folding. The difference between the two diagonals of the top surface of the carton with a combined size of less than or equal to 1000mm should not be greater than 3mm. The integrated deviation of the inner diameter of a single corrugated carton is not more than ± 2mm, and the double corrugated carton is not more than ± 4mm The difference between the two diagonals of the top surface of the carton with a size greater than 1000mm shall not be greater than 5mm. The comprehensive deviation of the inner diameter of a single-watt carton is not greater than ± 3mm, and the double-corrugated carton is not greater than ± 5mm.
The hole diameter of the box corner is not more than 4mm², and there must be no obvious wrap angle, and the outer swing cover should not be more than 2mm away from the seam or overlap.
The nail box shall not show the phenomenon of inverted nails, and the two pieces of box blanks with inconsistent faces, varieties and specifications shall not be mis-ordered together
Finally, after the first inspection is passed, the inspection shall be reported level by level.
The use of nail box equipment requires attention to safety, especially the use of ordinary nail box machines, especially the high-speed nail box surface of the hand and foot linkage, that is, the coordination of the hands, feet and eyes should be paid attention to, otherwise it is easy to hurt the hands.

Technical application and method of machine sticking box
Cardboard preparation
The requirements for the cardboard preparation of the machine sticking box are consistent with the requirements of the nail box.
Prepare adhesive
Ten minutes before the box-gluing operation, the operating staff will issue a picking list according to the production notice and pick it up from the warehouse. And check the label, quantity, date of the glue, and pay attention to the following common abnormal conditions when checking: obvious deterioration; the viscosity is not strong; there are impurities, agglomeration; discoloration;
Note: If any of the above conditions occur during production, the crew should record anomalies and provide feedback to the superior.
The adhesive to be used must be neatly placed in the specified area, and the number of applications shall not exceed the dedicated area;
The adhesive is blended as required before use.
Bonding
Try to stick
Put the blended adhesive into the glue bucket, open the glue valve, check whether the glue application of the paste wheel is uniform, such as uniform, try to glue one or two boxes, test the pressure resistance, check whether the glue is evenly coated on the glued cardboard On the tongue, it is appropriate not to overflow;
The width of the adhesive lap tongue is not less than 30mm, the adhesive should be coated evenly, adequately, and there is no overflow. When the adhesive surface is peeled off, the facial paper should not separate.
The first items to be inspected are the main items to be noted:
Sticking boxes require pattern alignment, and the error is controlled within 2mm;
When sticking the box, the two ends of the box piece should be aligned, and there should be no scissors mouth and stagger.
Process sampling
The 5 finished boxes should be fully inspected before the box-gluing machine is bonded. After the order is completed, it should be cleaned up uniformly to prevent the inclusion of defective products;
During the normal bonding process, at least one carton should be taken out of every 30 cartons to observe the printing, die cutting, and bonding; products that do not meet the quality requirements should be picked out to avoid mixing into the next process.
Any abnormality found in the random inspection should be adjusted in time;
After the end of this batch of orders, the returned and scrapped cartons should be sorted and placed according to different conditions of the cartons, and the number of scraps should be recorded and archived; the returned repairs will be handed over according to the process team leader handover system.
Technical application and method of manual sticking box
Cardboard preparation
This requirement is basically the same as the machine sticking box. Generally, it is sent to the sticking box by the crimping personnel or die cutting personnel. The sticking person is very close to the above process personnel.
Prepare adhesive
10 minutes before the manual operation, the operating staff issues a picking list according to the production notice and picks it up from the warehouse. Check the label, quantity, and date of the glue. When checking, pay attention to the following common abnormalities: obvious deterioration; low viscosity; impurities, agglomeration; discoloration.
Note: If any of the above conditions occur during production, the crew should record anomalies and provide feedback to the superior.
The adhesive to be used must be neatly placed in the prescribed area, and the number of applications shall not exceed the dedicated area.
The glue is blended as required before use.
Bonding
Try to stick
Use a brush to apply the prepared adhesive evenly on the binding tongue of the adhered cardboard, with no overflow as appropriate; try to glue one or two boxes and test the compression; the width of the adhesive lap tongue is not less than 30mm, the adhesive The coating should be uniform, sufficient, and free of overflow. The tissues should not separate when the adhesive surface is peeled off.
The process team leader and the squad leader each take a carton to conduct the first inspection of the products. The main items to be noted are as follows:
Glue box requires pattern alignment, and the error is controlled within 2mm.
When sticking the box, the two ends of the box piece should be aligned, and there should be no scissors mouth and stagger.
