The fully automatic L-shaped sealing and cutting packaging machine is an automatic packaging equipment that uses front and rear conveyor belts to send products into position. The photoelectric switch senses the product's position, and the PLC and other peripheral circuits control the pneumatic components and mechanical devices in combination. The actuator of this equipment is a cylinder, which is controlled to move forward and backward by a two-position five-way solenoid valve. The working position of the cylinder is detected by a magnetic switch and a proximity switch and fed back to the PLC. The PLC then issues control commands to the solenoid valve of the corresponding cylinder through the program to control the cylinder's movement. Through automatic control, the product's surface is sealed and cut with shrink film (POF shrink film is usually used).
After being packaged by the shrink machine, the items can be sealed, moisture-proof, and protected from contamination. It also protects the goods from external impacts and has a certain buffering effect, especially when packaging fragile items, it can prevent the items from scattering when broken. The design of the optimized and reasonable air duct, equipped with a precisely calculated fan power, ensures sufficient air circulation while reducing energy consumption and saving energy. The optimized and reasonable equipment shape, simple structure, and convenient maintenance minimize the preheating time, making it energy-efficient and highly efficient. The electronic stepless speed regulation and temperature control ensure a smooth temperature change, and the shrinkage does not affect the quality of the goods while achieving a perfect packaging effect. It is suitable for packaging regular or irregular items. This one-to-one and one-to-many mode also expands the application range of the shrink machine, and more adaptable shrink machines are emerging one after another.
The shrink packaging machine uses heating tubes to generate heat and uses a high-power fan to blow the hot air evenly from the heating chamber through a specially designed air knife. The shrinkage principle is that when the heat shrink film is heated at a constant temperature, the irregular arrangement of the original molecules changes. Under the radiation of hot air, the plastic molecules are closely arranged again, thus greatly reducing the original area and tightly adhering to the product surface to achieve the packaging purpose.
The heat shrink packaging machine has the following advantages:
1. It uses stainless steel heating tubes for heating, which have a long service life.
2. It uses a high-power fan through a specially designed air duct system to ensure uniform temperature.
3. It uses a constant temperature electronic control system to ensure the stability of the internal temperature of the machine.
4. The shrinkage does not affect the quality of the packaged items while achieving perfect shrinkage packaging.
5. It is suitable for packaging regular or irregular items.
Advantages of the fully automatic L-shaped sealing and cutting machine:
1. It adopts a unique constant force tensioning system, ensuring that the film does not jump or deviate, resulting in beautiful bag shapes and fast film feeding speed. It has strong adaptability to different specifications of packaging materials and accurate bag length photoelectric positioning.
2. It uses servo drive for film pulling, which is stable, reliable, accurate, and has a long service life.
3. It uses servo drive for transverse sealing (optional), with low working noise, fast speed, and stable sealing.
4. All electrical components are products of world-renowned brands, ensuring durability and reliability.
5. The longitudinal and transverse seals use unique alloy materials, which are durable and reliable and do not stick to the packaging materials. The surface treatment of the machine parts adopts advanced multi-layer chemical plating technology, making the surface less prone to rust.
6. There is a strict inspection and control system for parts processing to ensure the processing accuracy and appearance quality of the product, allowing the entire machine to operate stably for a long time.
7. It has an intuitive human-machine dialogue operation interface, making it convenient for operators.
8. The Japanese Keyence fiber optic tracking color standard has higher accuracy.
9. The high market share enables us to provide better and faster services.
10. Strong technical support allows us to meet the higher requirements of different customers.
11. Unmanned operation, can be directly connected to the production line for use.
12. The internal circulation system design reduces energy consumption; stainless steel heating tubes; movable roller transmission.
13. The sealing and cutting knife has an automatic protection function, effectively preventing accidental cutting of the packaged items.
14. The sealing and cutting and shrink packaging are continuously and automatically completed.
