All About Carton Stitching Machine

The carton stitching machine is a type of carton (especially corrugated cardboard) processing equipment, which is mainly used to firmly staple the folded carton pieces to make them into complete cartons.

It uses a mechanical device to nail the nails into the sealing position of the carton to achieve the function of connection and fixation to ensure that the structure of the carton is firm and can withstand a certain weight and pressure.

Carton stitching machine usually have different specifications and models, which can adapt to the stapling needs of cartons of different sizes and types, speed up the packaging process and firmly seal the boxes for transportation and storage, and improve the efficiency and quality of carton production.

Types of Carton Stitching Machines

There are mainly the following types of carton stitching machines:

1.  Manual carton box stitching machine: requires manual operation, has high labor intensity and relatively low efficiency, but is suitable for small-scale production or occasional nailing needs.


2.  Semi-automatic carton stitching machine: some operations require manual participation, such as paper feeding, but the nailing action can be completed automatically, and the efficiency is higher than manual.


3.  Fully automatic carton stitching machine: the entire process from paper feeding, folding, nailing to box delivery is fully automated, with high production efficiency and stable nailing quality, suitable for large-scale carton production.


In addition, according to the method and structure of nailing, it can also be divided into single nailing machine, double nailing machine, etc.; according to the size range of nailing boxes, there are different specifications and models.

How to choose a carton stapler with the right specifications?

When purchasing a carton stitcher, you can consider the following aspects to choose the right specifications:

  1. Carton size range: Determine the maximum and minimum sizes of the cartons you need to produce, including length, width and height. Choose a carton stitching machine that can adapt to these size ranges to ensure that it can handle your various product needs.
  2. Production speed requirements: Evaluate the required production speed of the stapler based on your production scale and order volume. If the output is large, you should choose a high-speed and efficient model.
  3. Stapling method: Common stapling methods include single nailing, double nailing, reinforced nailing,etc. Choose the appropriate stapling method according to the strength requirements and usage scenarios of the carton.
  4. Degree of automation: Consider your labor costs and production efficiency needs. Fully automatic staplers are easy to operate and efficient, but the price is relatively high; semi-automatic or manual staplers are cheaper and suitable for small-scale production.
  5. Equipment stability and reliability: Understand the manufacturing process, brand reputation and user reviews of the equipment, and choose products with good stability and low failure rate to reduce maintenance and downtime.
  6. Space limitation: Make sure the size of the carton stapler is suitable for your production site and there is enough space for installation and operation.
  7. Adjustment flexibility: Choose a carton stapler that can easily adjust parameters such as nail spacing and number of nails to meet the production needs of cartons of different specifications.
  8. After-sales service: Choose a supplier with good after-sales service support, including equipment installation and commissioning, training, repair and maintenance, etc., to ensure the normal operation of the equipment.

Considering the above factors comprehensively, you can choose the specifications of the carton stitcher that suits your production needs.

  1. Clearly define your needs: Consider factors like production speed, volume, and budget before searching.
  2. Research different models: Look for machines with features that suit your needs and compare prices from various sources.
  3. Check the machine’s condition: Ask for detailed descriptions, pictures, and ideally see the machine running before purchasing. Look for signs of wear and tear and inquire about any repairs or maintenance history.

How to correctly debug the corrugated box stitching machine?

The carton equipment adjustment should avoid blindness. Adjust the positions of the main baffle, left and right baffles, and the positions of the upper and lower nail heads according to the flap of the carton. Pay attention to the left and right baffles not to be clamped too tightly, and ensure that the cardboard can be inserted and pulled out smoothly.

After the mechanical adjustment is completed, set the touch screen computer: such as the height of the carton = the height of the original carton -40mm, the number of nails in the carton, the nail distance of the carton, the setting of whether to strengthen nails, etc., the selection of single and double sheets, etc. After all the above tasks are set up, trial production can be carried out.

If the thickness of the cardboard is too thick, personnel should be arranged to properly thin the binding part so that the tissue paper will not be crushed during binding. The nailing should be carried out in accordance with the requirements of the production notice, and the box nails should be nailed along the center line of the overlapping part, and the deviation should not exceed 3mm.

The nail distance should be uniform, the first and tail nails are 20mm from the upper and lower lines, the single nails are not more than 55mm, and the double nails are not more than 75mm. The two pieces of box blanks should be aligned, and there should be no overlapped nails, missing nails, warped nails, broken nails, bent nails, and no corners.

After the order is completed, the folded box of the carton should be square. The difference between the two diagonals of the top surface of the carton with a comprehensive size less than or equal to 1000mm should not be greater than 3mm. The comprehensive deviation of the inner diameter of the single corrugated box should be within ±2mm, and the double corrugated box Within ±4mm, the difference between the two diagonals of the top surface of the carton with a comprehensive size greater than 1000mm shall not be greater than 5mm, the comprehensive deviation of the inner diameter of the single-tile carton shall not be greater than 3mm, and the double-corrugated box shall not be greater than 5mm. The hole diameter of the box corner shall not be greater than 4mm2, and there shall be no obvious wrap angle, and the seam or overlap of the outer flap shall not be greater than 2mm.

The nail box shall not have the phenomenon of inverted head nails, and the two pieces of box blanks with inconsistent yin and yang surfaces, varieties, and specifications shall not be mistakenly stapled together. The ordered cartons will go into production after being inspected and qualified. When the nail box starts, the cardboard is fed by the servo motor, and the nail car motor drives the nail head to complete the nail box. The drive shaft driven by the nail head motor and equipped with a clutch and brake drives the crank mechanism to realize the nail box action under the action of the clutch. When the first nail action is completed, the cardboard backplane picks up the cardboard, and the crank mechanism moves in a stepping manner. Drive the paper feed roller to rotate, stop after reaching the predetermined nail pitch, and immediately perform the second nailing action.

The key to the nail box machine is the quality of the nail car and the nail head, and product quality failures often occur here.
