Semi-automatic nail box machine operation and troubleshooting (on)

With the continuous development of packaging technology, the appearance requirements of corrugated boxes are getting higher and higher, such as exquisite printing patterns, neat and beautiful nail line sealing boxes and so on. Therefore, fully automatic/semi-automatic nail box machines are also used more in cartons. Compared with the manual nail box machine, the automatic/semi-automatic nail box machine not only has high production efficiency, but also has a uniform and beautiful nail box. The main difference between the automatic nail box machine and the semi-automatic nail box machine is: the automation of paper feeding. The paper feed of the automatic nail box machine is the paper feeding device that folds the paper board and feeds it into the nail box section to carry out the nail box. The semi-automatic nail box machine manually folds and feeds the paper board.

Semi-automatic nail box machine is generally horizontal structure, divided into single-chip and double-chip nail box machine two types. The two-piece nail box machine structure is more complex and full-featured, capable of nailing a single piece of carton and a two-page carton. Here we introduce the two-piece nail box machine and hope to help everyone.

Composition structure

As shown in Figure 1: Hydraulic lifting paper-carrying platform, nail car host, finished conveyor, roller rack.

â–  The paper table is lifted by a hydraulic oil pump driven cylinder. The upper and lower limit position limit switches are installed, and the lower limit mechanical limit device is installed for protection. Light eye control automatically rises, maintains the paper-feeding height of the worker, and the paper board automatically drops after use, reducing the labor intensity and increasing the production efficiency.

â–  The staple car host includes: cardboard conveying mechanism, upper and lower nail heads, and finished product counts.

The paperboard conveying mechanism comprises: upper and lower four transmission rubber wheels, a feeding rubber wheel, a rear baffle adjusting device, a left and right baffle, a transmission mechanism and the like.

The feed roller adjusts the gap with an electric adjustment device, suitable for all types of cardboard with different thicknesses. Nail head composite drive design, combined with the advantages of gear box type and chain type transmission, is easy to repair and maintain, with low failure rate and high efficiency transmission.

â–  Electronic control system:

The color touch screen provides a good man-machine interface, completes the automatic setting of the nail pitch, strengthens the setting and cancellation of nails, and searches for faults.

PLC programmable controller system is stable and reliable.

The AC servo motor controls the cardboard advance and stop to ensure uniform and accurate nail pitch.
â–  Automatically counts the light and automatically counts the output of the finished product. It can be set to separate and send, and it can be used in conjunction with the end of the machine.

â–  The key to the nail box machine is the quality of the nail car and the nail head. Nail head is made of special steel and it is made of patented swing type forming block, which is lightweight and practical.

Basic operation

â–  Preparation process before nail box:

Adjust the position of the main baffle according to the flap cover of the carton; adjust the position of the left and right baffles and the position of the upper and lower nail heads, pay attention to the tightness of the left and right baffles, and ensure that the cardboard is inserted and pulled out smoothly; after the mechanical adjustment is completed Touch screen computer settings:
Carton height = original carton height - 40mm
Carton nails

Carton staple distance

Do you need to strengthen nail setting work?

Monolithic, dual-chip options

After the above tasks are all set, the nail box can be used.

â–  Actual process of nail box:

The servo motor feeds the cardboard, and the staple car motor drives the nail head to complete the nail box. The drive shaft driven by a nail head motor and equipped with clutches and brakes drives the crank mechanism to actuate the nail box under the action of the clutch. When the first nail action is completed, the cardboard back plate picks up the cardboard, and the crank mechanism operates in a stepping manner. Drive the feed roller to rotate, stop after reaching the predetermined staple distance, and immediately perform the second nail.
