The three-side sealing/center sealing dual-purpose bag making machine is a multi-functional bag making equipment that can flexibly switch between the production modes of three-side sealing bags and center sealing bags. It is widely used in the packaging fields of food, medicine, chemical industry and other industries. The following is a detailed introduction from two aspects of performance and characteristics:
- Bag Type Range: It can produce three-side sealing bags (three sides of the bag body are sealed, and one side is open) and center sealing bags (the middle of the bag body is longitudinally sealed, with both sides open or the bottom sealed), meeting the packaging needs of different products.
- Size Adjustment: Through mechanical or electronic adjustment devices, parameters such as bag length, bag width, and sealing width can be flexibly adjusted to adapt to various specifications of packaging bags (from small snack bags to large daily necessities packaging bags).
- High-speed Operation: Driven by servo motors or frequency conversion motors, combined with a high-precision transmission system, the bag making speed can reach 30-120 pieces per minute (specifically depending on the complexity of the bag type and material characteristics).
- Continuous Operation: It has functions such as automatic feeding, sealing, cutting, and counting, enabling 24-hour continuous production and reducing manual intervention.
- Sealing Method: Adopting heat sealing, cold sealing, or ultrasonic sealing technology, the sealing has high strength and good tightness, effectively preventing the leakage of contents.
- Temperature Control: Equipped with an intelligent temperature control system, it can accurately control the sealing temperature to adapt to the heat sealing requirements of different materials (such as PE, PP, composite films, etc.).
- Intelligent Control: Equipped with PLC (Programmable Logic Controller) and a touch screen human-machine interface, it can realize functions such as parameter setting, production monitoring, and fault alarm, with simple operation.
- Deviation Correction System: Equipped with a photoelectric deviation correction device, it real-time detects material deviation and automatically adjusts to ensure the bag type is neat and the sealing position is accurate.
It can process various packaging materials such as single-layer films, composite films, and aluminized films.
- By replacing a small number of molds (such as sealing components, cutters, etc.) or adjusting parameters, the production switch between three-side sealing bags and center sealing bags can be quickly realized, reducing the model change time and improving equipment utilization.
- It is suitable for multi-variety, small-batch, or mass production scenarios to meet the diversified packaging needs of customers.
- Using imported bearings, guides, and other precision components, combined with a servo drive system, the bag making precision is high (bag length error ≤ ±0.5mm, sealing position error ≤ ±1mm).
- The equipment runs smoothly with little vibration, which can reduce material loss and reject rate (the reject rate is usually ≤1%).
- Adopting energy-saving heating elements and high-efficiency motors, the energy consumption is 10%-20% lower than that of traditional bag making machines.
- Some models are equipped with exhaust gas collection devices to reduce the emission of odors and harmful substances generated during the heat sealing process.
- The open structure design makes key components (such as sealing molds, cutters) easy to disassemble and clean, with low maintenance costs.
- Equipped with a fault diagnosis system, it can display the fault points in real time, facilitating quick repair.
It is equipped with emergency stop buttons, safety light curtains, overload protection and other devices to prevent operators from accidental touch or equipment overload operation and ensure production safety.
Optional punching devices (such as hanging holes, air holes), labeling devices, inkjet printers, etc. can be equipped to meet personalized packaging needs (such as shopping bags with hand holes, food bags with production dates).
- Three-side Sealing Bags: Commonly used for packaging small items such as snacks, candies, medicines, and small hardware. The bag type is beautiful and has good tightness.
- Center Sealing Bags: Suitable for packaging granular or powdery products such as rice, flour, and washing powder. Self-supporting bags can be formed by bottom sealing, which is convenient for display and storage.
- Pay attention to core performance indicators such as bag making speed, size range, and sealing precision, and select the appropriate model (such as high-speed type, multi-functional type) according to production needs.
- Consider material characteristics (such as thickness, heat sealability) to ensure that the equipment matches the materials and avoid poor sealing or equipment damage.
- Give priority to brand manufacturers, whose equipment stability and after-sales service are more guaranteed.
In summary, the three-side sealing/center sealing dual-purpose bag making machine has become an important equipment to meet diversified bag making needs in the packaging industry with its flexible functions, efficient performance, and wide adaptability. |
