Common Issues and Solutions for Automatic Window Patching Machine

In daily life, when consumers are more satisfied with a product, manufacturers usually need to consider many details, such as packaging. During the window pasting process, every detail problem may affect the final quality of the product. Our company will answer these questions one by one for printing factories and analyze the automatic window patching machine fault solutions.

The automatic window patching machine takes a long time to change version

Preparation work before version change should be done well. Based on the centerline of the device, setting the die-cutting tool accurately and conveniently, including full-size die-cutting plate, pre-installed bottom template, etc. At the same time, pre-installing the tools outside the machine and micro-adjusting on the machine can further reduce the adjustment time for repeated products. Under a good management system, the version change time of the repeated products usually requires automatic waste removal, which can be completed within 30 minutes.

The automatic window patching machine has poor printing and cutting accuracy

The demand for high-quality printed products is increasing day by day, and the design of packaging boxes is becoming more and more complex. The requirements for the quality and accuracy of the die-cutting of complex boxes have correspondingly increased. In order to maintain an error range of 0.15mm, a qualified automatic window patching machine must be used, and attention should be paid to adjusting steps, especially the timing of the feeder and the paper.

The quality of the automatic window patching machine is poor, with more paper hair

Low-quality cardboard, such as recycled cardboard, makes the die-cutting process more difficult. To achieve better die-cutting quality, the operator must find the correct method, especially the method of bottom filling. By gradually increasing the pressure and supplementing it in the area, the sharpness of the cutting tool can be maintained. For products that use a large number of cutting wires, the balance of the cutting disc is crucial, which can significantly reduce the suppression time. In addition, different hardness tapes should be selected according to the requirements of different products, such as typesetting and cardboard quality.

There are too many and too large connecting points for the automatic window patching machine

The final users of cartons always need smaller and smaller connecting points, and manufacturers always make automatic window patching machines run faster, which increases the difficulty for operators. In order to reduce the difficulty, the connection points should be hammered at the stress points with a grinder. Hard tape or soft cork should be used at the blade edge where the connection points need to be struck to prevent the connection points from breaking, so that the connection points can become smaller and smaller.

The marking of the automatic window patching machine is irregular

Considering the need for folding cartons to be pasted, the carton must have good crease lines, and when these boxes are running on an automatic packaging machine, the opening force must be stable and consistent. Therefore, choosing the appropriate type of marking line during die-cutting is a basic element. Depending on the thickness of the paper, the height and width of the wire should be selected, and the appropriate wire should be pasted on the die-cutting bottom plate, so that the crease can achieve higher quality and make it easier to paste the film.

The automatic window patching machine has a high rejection rate

The waste rate of most printing factories is usually high. At the beginning of calibration of automatic window patching machine, there will be some waste, which can be reduced by using appropriate tools and correct steps. The waste generated during operation is caused by shutdown and paper jam. Correct adjustment and accurate tool preparation can reduce the waste rate. In addition, manual waste removal will also increase the waste rate and reduce the profit margin.
