[0002] Food packaging is a crucial step in food processing, primarily aimed at ensuring food quality and safety, thereby facilitating transportation and sales. When processing large quantities of food, mechanical processing is preferred, utilizing automated machinery for packaging due to its higher efficiency.

[0003] Packaging bags are bags used to package various goods and are widely used in daily life and industrial production. The development of packaging bags has gone through four distinct stages: the primitive packaging bag stage, the large packaging bag stage, the small packaging bag stage, and currently, gradually entering a new stage of environmentally friendly (green) packaging bags. With the development of the commodity economy, the commodity nature of packaging itself has become increasingly prominent. It has become a special product no longer dependent on commodity production, a widely used product that all commodities cannot do without.

[0004] The existing CN103395514A packaging bag opening machine is suitable for material packaging, especially for packaging long products such as pipes and profiles. Once the bag opening is opened, the bag can remain open indefinitely until the entire roll of bags is used up. It prevents the bag from being unable to open due to wrinkles or external factors, improving automated production efficiency. However, it has shortcomings: the existing equipment lacks adaptability and flexibility, and the filling effect is poor, making it inconvenient to use. Therefore, a new packaging bag opening machine for food sealing is needed to solve these problems. Utility Model Content

The vertical support block 1, the horizontal support block 10 and the opening block 15 are symmetrically distributed on the outer wall of the baffle 4. The vertical support block 1, the horizontal support block 10 and the opening block 15 are installed in a plugging-in manner with the baffle 4 through the positioning slot 17 and the positioning plug 18. The positioning plug 18 is locked and fixedly connected to the baffle 4 through the locking knob 16. This makes it easy to quickly plug in and disassemble the vertical support block 1, the horizontal support block 10 and the opening block 15, and facilitates replacement and maintenance.

[0022] The material box 3 is installed on the upper corner of the support base 2, and the material box 3 is connected to the lower center of the material box 3 with the material outlet 12. The material outlet 12 is connected to the material box 3 through the regulating valve 6 to open and close. The fan 13 is symmetrically distributed with the material outlet 12 in a protruding and inclined position. This makes it easy to adjust the material outlet 12 for filling, and the fan 13 can blow the packaging bag open, resulting in a good filling effect.

[0023] A regulating valve 6 is installed on the discharge port 12, and a fan 13 is electrically connected to both sides of the regulating valve 6. A second electric push rod 8 is vertically installed on one side of the outer wall of the baffle 4, and a limit support block 11 is installed at the output end of the second electric push rod 8.

[0026] Working principle: When using the food packaging bag opening machine, first assemble and install the device, then connect it to the power supply. When the packaging bag is placed on the conveyor belt 5, the limiting support block 11 can be moved inward by the second electric push rod 8 according to the thickness of the packaging bag to limit the transport of the packaging bag. When it moves to the discharge port 12, the opening block 15 can be moved to the opening of the packaging bag by the fourth electric push rod 19, and then suction and fixation are performed by the suction pipe 14. Then, the fourth electric push rod 19 is contracted to open the packaging bag. Then, the fan 13 blows air onto the packaging bag to expand it. Then, the material is injected through the discharge port 12. During the injection, the auxiliary limiting support block 20 can be adjusted by the third electric push rod 9. After the injection is completed, the suction can be released, and the transport can continue. When the opening block 15 is damaged, it can be replaced independently by inserting and locking the locking and disassembling the locking knob 16, positioning slot 17, and positioning insert 18. This is the operation process of the food packaging bag opening machine.
