[0002] High temperature resistant packaging bags are a kind of packaging material with moisture-proof, high temperature resistant, waterproof and anti-oxidation properties, and are commonly used in food, medicine, chemical and other fields. They are usually made of polymer materials such as polyester, polyamide, polyimide, polytetrafluoroethylene, etc. They have good high temperature resistance, can maintain stable performance in high temperature environments, and can effectively protect the quality and safety of packaging.

[0003] The production process of high-temperature packaging bags probably includes raw material preparation, printing, cutting, heat sealing, packaging, inspection, etc. Heat sealing is to ensure that the bag mouth has good sealing performance. However, since the packaging bags are made of flexible materials, in order to ensure the flatness of the packaging bags during heat sealing, the staff needs to manually inspect and flatten the heat seals. During the long production process of packaging bags, the staff is prone to negligence, resulting in unsatisfactory flattening of the packaging bags, affecting the heat sealing effect of the packaging bags, and also increasing the workload and the time required for overall heat sealing. In view of this, we propose a production equipment for high-temperature resistant packaging bags. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The production equipment for high-temperature resistant packaging bags will synchronously drive the pressure plate to move in the vertical direction after the threaded rod rotates, and then use the pressure plate to fix the packaging bag, and then use the driving component to drive the slider to slide inside the inclined groove, and then use the slider to drive the telescopic plate to move. Since the inclined groove is inclined as a whole, it will gradually move downward when the telescopic plate moves, so that the flat plate will contact the packaging bag. After contact, the packaging bag will be flattened with the help of the flat plate. When the telescopic plate continues to move, the flat plate will enter the interior of the telescopic plate and compress the spring. Through the above structure, when the packaging bag is sealed, the sealing part of the packaging bag can be flattened by the flat plate, avoiding the presence of wrinkles at the sealing part, thereby affecting the sealing effect and the aesthetics of the packaging bag.

[0015] (2) After leveling, the production equipment for high temperature resistant packaging bags uses the hydraulic telescopic rod to push the heat sealing knife downward again, and uses the tension of the spring in the inclined groove to reset the slider. When heat sealing, the ejector can be used to pierce a hole at the heat seal. When adjusting the heat seal of different depths, the baffle can be driven to move by rotating the second threaded rod to adapt to the seal of different depths. Through the above structure, not only can the ejector be used to pierce a hole to facilitate subsequent tearing, but the baffle can also be used to facilitate the positioning of the seals of different depths, thereby improving the positioning speed and accuracy.

The spring 11 is fixedly connected, and the slider 9 is provided with a driving assembly. When the high temperature resistant packaging bag is sealed, the high temperature resistant packaging bag is placed on the upper surface of the working platform 1, and then the motor 4 is used to drive the threaded rod 7 to rotate. Since the pressing plate 6 is limited in its movement trajectory by the limiting groove 5, the pressing plate 6 will be synchronously driven to move in the vertical direction after the threaded rod 7 rotates, and then the packaging bag is fixed by the pressing plate 6, and then the driving assembly is used to drive the slider 9 to slide inside the inclined groove 8, and then the slider 9 is used to drive the telescopic plate 10 to move. Since the inclined groove 8 is inclined as a whole, the telescopic plate 10 will gradually move downward when it moves, so that the screed plate 12 contacts with the packaging bag. After contact, the packaging bag is flattened with the help of the screed plate 12. When the telescopic plate 10 continues to move, the screed plate 12 will enter the interior of the telescopic plate 10 and compress the spring 11. Through the above structure, when the packaging bag is sealed, the sealing part of the packaging bag can be flattened by the screed plate 12 to avoid wrinkles at the sealing part that affect the sealing effect and the aesthetics of the packaging bag.

The lower surface of the heat sealing knife 15 is provided with a groove 19, and the top wall of the groove 19 is fixedly connected with an ejector pin 20. The upper surface of the working platform 1 is fixedly connected with a limiting rod 21, and the upper end of the limiting rod 21 is fixedly connected to the lower surface of the mounting plate 3. The protrusion 16 is slidably sleeved on the outer surface of the limiting rod 21. The upper surface of the working platform 1 is provided with a sliding groove 22.

When the heat sealing knife 15 is pulled up, the protrusion 16 will be driven to move synchronously. After the protrusion 16 moves, the cable 13 is used to pull the slider 9 to move, and when the cable 13 moves, the guide shaft 18 can be used to reduce the wear of the cable 13, After being leveled, the heat sealing knife 15 is pushed downward by the hydraulic telescopic rod 17 again, and the slider 9 is reset by the pulling force of the spring 11 in the inclined groove 8. When heat sealing, the ejector pin 20 can be used to pierce a hole at the heat seal. When adjusting the heat seals of different depths, the baffle plate 23 can be driven to move by rotating the second threaded rod 24 to adapt to seals of different depths. Through the above structure, not only can the ejector pin 20 be used to pierce a hole for subsequent tearing, but the baffle plate 23 can also be used to facilitate the positioning of seals of different depths, thereby improving the positioning speed and accuracy.

[0026] Working principle: When sealing the high temperature resistant packaging bag, place the high temperature resistant packaging bag on the upper surface of the working platform 1, and then use the motor 4 to drive the threaded rod 7 to rotate. Since the pressing plate 6 is limited in its movement trajectory by the limiting groove 5, the pressing plate 6 will be synchronously driven to move in the vertical direction after the threaded rod 7 rotates, and then the packaging bag is fixed by the pressing plate 6. Then, the driving component is used to drive the slider 9 to slide inside the inclined groove 8, and then the slider 9 is used to drive the telescopic plate 10 to move. Since the inclined groove 8 is inclined as a whole, the telescopic plate 10 will gradually move downward when it moves, so that the flat plate 12 will contact with the packaging bag.

When the heat sealing knife 15 is pulled up, it will simultaneously drive the protrusion 16 to move. After the protrusion 16 moves, the cable 13 is used to pull the slider 9 to move, and when the cable 13 moves, the wear of the cable 13 can be reduced with the help of the guide shaft 18. After leveling, the hydraulic telescopic rod 17 is used again to push the heat sealing knife 15 downward, and the slider 9 is reset by the tension of the spring 11. When heat sealing, the ejector pin 20 can be used to pierce a hole in the heat seal. When adjusting the heat seal of different depths, the baffle 23 can be driven to move by rotating the second threaded rod 24 to adapt to seals of different depths.
