■Hot sealing and stitching workflow


Bag cleaning (optional) → Knife trimming bag opening → Inner bag heat sealing (heated by 4 sets of heating blocks) → Press roller pressing → Sewing machine outer bag sewing → Hot melt tape → Heat sealing (heated by 2 sets of heating blocks) → Press roller pressing
■Working characteristics
The heat sealing and suturing machine adopts a controller, a motor variable frequency speed controller, and a heating system detection device to form the main body of the control system, achieving coordinated control of the entire heat sealing machine. The system has heating system detection, automatic alarm shutdown, fault display functions, and complete fault protection and interlock shutdown functions. The entire operating system is easy to use, fully functional, and convenient for maintenance and repair. The entire equipment consists of an automatic import device, an automatic heat sealing device, an automatic sewing and packaging device, an automatic hot melt paper sealing device, and an on-site control cabinet. Realize the integration of heat sealing inner film, outer bag seam, and hot melt paper heat sealing process, effectively improving work efficiency and reducing labor costs.

scope of application |
1. The melting point of the outer bag is between 140 ℃ and 150 ℃, and the melting point of the inner bag is 100 ℃ (with a temperature difference of 30-50 ℃ or more between the inner and outer bags) The distance from the material to the top of the bag should not be less than 250mm. 3. The inner PE bag and outer bag openings must be flush at the top and glued together. |
