Different user companies have different requirements for bag packaging equipment, so the selection of equipment depends on the needs of the enterprise. For example, if the product is a powdery food enterprise, because of its large production volume and single variety, the packaging machinery is required to have stable performance and high speed. The single-roller powder packaging machine produced by Gessen can meet the above requirements very well, because the equipment adopts many unique designs: firstly, the longitudinal seal and the transverse seal are completed on the same pair of rollers, and the structure is compact; secondly, the change is made. The traditional vertical packaging machine moves the film vertically and changes the film to a certain angle. The third and most important point is the use of the gate type feeder. When the vertical packaging machine packs the powder, the powder falls into the bottom of the bag for a certain period of time. At this time, the phenomenon of powdering and engraving is easy to occur, which affects the packaging speed and quality. The gate type hopper can solve this problem very well. It has a gate at the top and penetrates the bottom of the bag. When the powder falls into the gate hopper, the gate opens, avoiding the phenomenon of powder and jamming. The packaging speed is also greatly improved. In actual production, the packaging speed of this single-roller powder packaging machine can be stabilized at 110 bags / min ~ 120 bags / min, up to 150 bags / min.
However, the advantages of the single-roller powder packaging machine are outstanding, and the disadvantages are also obvious, that is, the bag length cannot be freely changed and adjusted. Therefore, it is not suitable for companies that need to change product varieties frequently. At present, many food companies require high degree of automation and reasonable price for packaging machinery to meet the production requirements of small batches and varieties. To this end, Gessen has developed a two-stage roller-type packaging machine driven by a stepper motor. The machine has two main features: First, the degree of automation is high, and the display screen is installed on the control panel of the packaging machine to adjust the length of the bag. The technical parameters can be directly completed on the screen, and the operation is extremely convenient. Secondly, the stepping motor drive is relatively low in cost compared with the servo drive. In this way, it not only meets the requirements of the user enterprise but also reduces the cost.
The roller type liquid pouch packaging machine generally adopts a three-stage type, the first section is a longitudinally sealed hot roller, the second section is a horizontally sealed hot roller, and the third section is a cooling sealing roller. The third section of the cooling sealing roller is pressed under the condition that the transverse sealing has been heat-sealed, so as to make the horizontal sealing more firm, flat, beautiful and non-leakage. This not only greatly improves the product yield, but also the packaging speed of 120 bags / min ~ 180 bags / min. Such packaging machines have been widely used in cosmetics, instant noodles, pesticides and other industries.
From the development trend of roller-type pouch packaging machinery, there are two aspects worthy of attention: First, high-end, customers hope to complete as many production tasks as possible with as few people as possible; second, low-end, price is an important factor in market competition Who can complete the same packaging task at a lower price, who will be able to compete in an invincible position, which also requires equipment updates and technical improvements. In short, whether it is high-end or low-end. There is only one purpose: to meet the needs of customers. Therefore, for the end user of the bag packaging machine, the best is suitable.
