TECHNICAL FIELD

[0001] The utility model relates to the field of heat sealing, especially to the plastic woven bag production heat sealing device. BACKGROUND

[0002] The heat sealing device is a device that uses heat energy to heat the sealing part of packaging materials (such as plastic film, woven bag, etc.) to a molten state and makes them adhere together through pressure. This technology is widely used in various packaging industries to achieve sealing and preservation of packaging.

[0003] After searching, the existing Chinese patent No. CN219468193U provides a packaging outer plastic bag heat sealing device. This patent puts the plastic bag containing goods into the box, so that the staff no longer needs to hold the plastic bag with their hands to achieve sealing operation, thereby saving time and improving sealing efficiency. Through the cooperation of the stepping motor, lead screw, first cylinder and box, the position of the plastic bag opening and the placement plate is adjusted, which facilitates the plastic bag to be sealed to the placement plate. By rotating the four bolts, the rubber soft disc can press the plastic bag opening tightly, ensuring that the plastic bag will not fall off the placement plate.
