Window patching machine is a kind of equipment used to paste transparent windows on packaging materials such as cartons and paper bags. Its production process involves multiple links, including material preparation, window cutting, glue coating, lamination, flattening and finished product stacking. The following are the main production process steps of window patching machine:
- Material preparation
Paper or cardboard: Select suitable paper or cardboard as packaging material to ensure that its thickness, strength and printing effect meet the requirements.
Transparent film: Select film materials with high transparency and good toughness (such as PET, PVC, OPP, etc.) for making windows.
Glue: Select appropriate glue (such as hot melt glue, cold glue, etc.) according to the characteristics of the material to ensure strong and environmentally friendly bonding.
- Window cutting
Die-cutting process: Use a die-cutting machine or laser cutting machine to cut the transparent film into the required window shape and size.
Precision control: Ensure that the cutting edges are neat and the size is accurate to avoid burrs or size deviations.
- Glue coating
Glue coating method: According to the design requirements, use roller coating, spraying or dispensing to evenly apply glue on the edge of the window or the window area of the paper.
Glue quantity control: Accurately control the amount of glue to avoid excessive glue causing overflow or too little glue causing weak bonding.
- Laminating process
Positioning and laminating: Accurately laminating the cut transparent film to the window position of the paper to ensure that the window is consistent with the designed position.
Pressure control: Apply appropriate pressure through the pressure roller or pressure plate to ensure that the film and paper are tightly fitted to avoid bubbles or warping.
- Flattening and curing
Flattening treatment: Use a flattening device to flatten the window after lamination to ensure that the window surface is flat.
Glue curing: According to the characteristics of the glue, it is cured by natural drying or heating to ensure strong bonding.
- Quality inspection
Appearance inspection: Check whether the window is flat and transparent, and whether there are bubbles, stains or glue residues.
Size detection: Ensure that the window position and size meet the design requirements.
Adhesion strength test: Test the adhesion strength between the window and the paper to ensure that it will not fall off during transportation and use.
- Finished product stacking and packaging
Automatic stacking: The finished products are neatly stacked through automated equipment for subsequent packaging and transportation.
Packaging protection: Use protective film or cardboard to package the finished products to prevent damage during transportation.
- Environmental protection and cleaning
Waste recycling: Recycle the film scraps after cutting to reduce waste.
Equipment cleaning: Clean the equipment regularly to avoid glue residue or dust affecting production quality.
Key process control points
Precision control: Ensure the accuracy of window cutting and lamination to avoid deviation.
Glue coating uniformity: Glue coating should be uniform to avoid affecting the bonding effect.
Pressure control: The pressure during lamination should be moderate to avoid damaging the material or generating bubbles.
Production efficiency: Optimize the process flow, increase production speed, and ensure quality at the same time.
Summary
The production process of window patching machines involves multiple links such as material preparation, window cutting, glue coating, lamination, flattening, quality inspection and finished product stacking. Each link needs to be strictly controlled to ensure the quality and performance of the final product. With the development of automation and intelligent technology, the production process of window patching machines will be more efficient, accurate and environmentally friendly, meeting the market demand for high-quality packaging.
