Application Areas of Pillow Packing Machine
The versatility of pillow packaging machines makes them suitable for a wide array of industries. Their primary applications include:
Features of Pillow Pack Machine
- Three servo controls and automatic detection of product length and cutting: operators do not need to adjust unloading work, saving time and film.
- Fault self-diagnosis function, with clear fault display.
- High-sensitivity photoelectric color code tracking and digital input cutting position make sealing and cutting more accurate.
- Temperature-independent PID control, suitable for various packaging materials.
- Stop the machine at the selected position, without sticking the knife or wasting packaging film.
- All controls are implemented by software, making it easy to adjust and upgrade functions.
Details of Pillow Pack Machine
Linked film roll axis
Adopting multiple linkage film rolling shafts to coordinate the film pulling process, adapting to more film rolling materials, and making film rolling smoother.
Automatic feeding device
Neat cutting and quick packaging. It can achieve uninterrupted and uniform material transportation, avoiding material interruption caused by inconsistent operation rhythm during manual feeding.
Sealing device
Two independent temperature controls ensure sealing. Manual adjustment is easier to master, and fine adjustment makes the packaging more exquisite.
End sealing cutting device
Thermostatic heat sealing cutter, with a complete and beautiful seal. Avoiding the phenomenon of rolling holes, improving efficiency, and increasing output.
How Does The Pillow Packing Machine Work?
The operation of a pillow packaging machine is a continuous, synchronized process that can be broken down into four key stages:
1. Film Feeding & Forming: A roll of flat packaging film is mounted on the back of the machine. The film is drawn over a forming collar, which gently shapes the flat film into a continuous tube around a vertical filling tube.
2. Longitudinal Sealing: As the film is pulled down over the filling tube, the two edges of the film overlap. A longitudinal sealer bar instantly heats and fuses these edges together, creating a tight, secure back seal on the package.
3. Product Filling: The product is fed into the top of the filling tube via a conveyor or feeding system. It drops freely down through the tube and into the newly formed film tube below.
4. Transverse Sealing & Cutting: A pair of synchronized sealing jaws close across the film tube below the product. These jaws perform two functions simultaneously: they seal the top of the filled package and the bottom of the next package-to-be, and a cutting mechanism separates the finished pack. The sealed package is then released onto a discharge conveyor. This cycle repeats continuously at high speed.
FAQs of Pillow Packing Machine
-
What materials is the pillow packaging machine suitable for?
Pillow packaging machines are mainly suitable for solid materials in block, strip, sheet, and regular shapes, such as biscuits, bread, instant noodles, masks, stationery, hardware parts, etc. For materials that are prone to scattering, liquid or irregular in shape (such as powders, sauces), specialized feeding devices or customized molds are required.
-
How to quickly debug packaging parameters during initial use?
Adjust the bag length according to the material size first (set through the control panel or mechanical adjustment lever);
Set packaging speed (starting from low speed and gradually increasing to steady state);
Adjust the edge sealing temperature (depending on the packaging film material: PE film about 120-180 ℃, composite film about 150-220 ℃);
Calibrate the material conveying positioning to ensure that the material enters the packaging film in the center.
-
What parameters need to be adjusted for packaging films of different materials?
Heat sealing temperature: Aluminum foil composite film > Aluminum plated film > PE film (refer to the recommendations of the film material supplier for details);
Heat sealing time: For thick films, the heat sealing time needs to be extended, while for thin and brittle films, it needs to be shortened to avoid burning through.
Traction speed: Match with packaging speed to prevent film stretching or wrinkling.
-
Is the sealing of the packaging film not secure or missing?
Possible reasons: low heat sealing temperature, insufficient heat sealing knife pressure, or mismatched packaging film material.
Solution: Increase the heat sealing temperature (5-10℃ each time), adjust the spring pressure of the heat sealing knife, and replace the suitable heat sealing packaging film.
-
Is there wrinkling or deviation after packaging?
Possible reasons: uneven tension of the film material, wear of the traction wheel, and material positioning deviation.
Solution: Adjust the tension rod of the film frame (with consistent tightness), replace worn traction wheels or clean the oil stains on the wheel surface, and calibrate the material conveying track of the feeding device.
