[0002] Composite film packaging bags are widely used in the food, medicine, daily necessities and other industries due to their excellent performance and wide application fields. However, after the composite film packaging bags are processed and formed, the packaging bags stacked on the pallet often have a "warping corner" phenomenon, that is, the edge of the packaging bag is warped upward, which not only affects the appearance quality of the packaging bag, but also may cause the sealing performance of the packaging bag to decrease, affecting its protective effect on the contents. In addition, the composite film packaging bags need to be aged after production, such as the patent publication number CN215151031U disclosed A packaging film composite curing device is disclosed, which specifically discloses a film roll positioning component and a heating and heating component provided in a heat-insulating cover component. The packaging film coil is supported by the film roll positioning component, and the internal environment of the heat-insulating cover component is made to reach the curing temperature of the packaging film by the heating and heating component. However, since the temperature and humidity distribution in the curing chamber (heat-insulating cover component) are uneven, and the packaging film is a coil, the inner and outer layers of the coil are heated differently, the adhesive reaction is insufficient, and there are problems such as the packaging bag is prone to warping, the packaging bag is not fully cured, and it is prone to delamination and cracking.

Embodiment

[0022] Please refer to Figures 1-10 , the present invention provides a technical solution: A secondary aging device with an anti-warping function for the production of composite packaging bags, including a packaging bag placing rack 3 arranged in a heat preservation chamber 1. The bottom of the heat preservation chamber 1 is of an open structure, and the bottoms of the heat preservation chamber 1 and the packaging bag placing rack 3 are both arranged on the ground; a switching door 2 is hinged on the front side wall of the heat preservation chamber 1;

[0023] The packaging bag placing rack 3 includes two vertically arranged frame beams 31 that are symmetrically arranged left and right. A cross beam 32 is arranged between the middle positions at the tops of the vertical frame beams 31, and a bottom plate 33 is arranged between the bottoms of the vertical frame beams 31. A slope 331 is arranged at the front end of the bottom plate 33; a telescopic cylinder 4 is vertically arranged at the middle position at the top of the heat preservation chamber 1. The telescopic end of the telescopic cylinder 4 faces downward and penetrates into the heat preservation chamber 1. A first relief hole 321 is opened on the cross beam 32 at the position corresponding to the telescopic end of the telescopic cylinder 4. The telescopic end of the telescopic cylinder 4 penetrates through the first relief hole 321 and is fixedly connected with a lifting pressure plate 5 through a pressure sensor 6; guiding rods 7 are symmetrically arranged on the left and right sides of the top surface of the lifting pressure plate 5. Second relief holes 322 are opened on the cross beam 32 at the positions corresponding to the guiding rods 7. Guide sleeves 8 are arranged at the bottom ends of the cross beam 32 at the positions of the second relief holes 322. The top ends of the guiding rods 7 all penetrate through the corresponding guide sleeves 8 and the second relief holes 322 and extend outside the heat preservation chamber 1;

[0024] One side wall of the heat preservation chamber 1 is provided with a heater 9; an ultrasonic humidifier 10 is arranged outside the heat preservation chamber 1, and the humidifying pipe 101 of the ultrasonic humidifier 10 penetrates into the heat preservation chamber 1. The heat preservation chamber 1 is also provided with a humidity display meter 12 and a temperature display meter 13.

[0025] Working principle:

[0026] Use a forklift to send the packaging bags stacked on the pallet into the heat preservation chamber 1, and place the packaging bags stacked on the pallet on the bottom plate 33. The slope 331 facilitates the forklift to move onto the bottom plate 33; then move the forklift outside the heat preservation chamber 1, drive the lifting pressure plate 5 to descend through the telescopic end of the telescopic cylinder 4, so that the lifting pressure plate 5 presses the packaging bags stacked on the pallet. When the pressure applied by the telescopic cylinder 4 to the lifting pressure plate 5 reaches the value set by the pressure sensor 6, the telescopic end of the telescopic cylinder 4 stops extending. Close the switch door 2 and turn on the heater 9 to increase the internal environmental temperature of the heat preservation chamber 1. Turn on the ultrasonic humidifier 10 to increase the internal environmental humidity of the heat preservation chamber 1, and display the temperature and humidity inside the heat preservation chamber 1 through the temperature display meter 13 and the humidity display meter 12 respectively; during the lifting process of the lifting pressure plate 5, the guide rod 7 plays a guiding role in the lifting of the lifting pressure plate 5;

[0027] Flatten the packaging bags stacked on the pallet through the lifting pressure plate 5 to prevent the processed and formed packaging bags from having warped corners; and make the internal environment of the heat preservation chamber 1 reach the ripening conditions through the heater 9 and the ultrasonic humidifier 10, and perform secondary ripening on the processed and formed packaging bags to ensure complete ripening of the packaging bags and prevent the packaging bags from delaminating and cracking due to incomplete ripening. The structure is simple, the operation is convenient, and it saves time and effort.

[0028] Further, the lifting pressure plate 5 includes a pressure plate body 51, the pressure sensor 6 is fixedly arranged on the pressure plate body 51, and a reinforcing frame 52 is welded on the top surface of the pressure plate body 51; the structural strength of the pressure plate body 51 is increased through the reinforcing frame 52.

[0029] Further, the switch door 2 is of a double-leaf door structure. A sealing edge 23 is provided at the free end of the right door leaf of the switch door 2. A vertically arranged rotating shaft 21 is rotatably provided on the right door leaf. A locking cam 22 is fixedly provided at the top end of the rotating shaft 21. A ring groove 221 is formed along the outer edge contour on the circumferential outer wall of the locking cam 22. A locking block 11 is fixedly provided on the heat preservation chamber 1 at a position corresponding to the locking cam 22. At the left and right ends of the front side wall of the locking block 11, a first limiting plate 111 and a second limiting plate 112 are respectively provided. The second limiting plate 112 is of a hook-shaped structure. An arc-shaped guiding rib 113 is provided between the inner side end of the second limiting plate 112 and the front side wall of the locking block 11. A clamping groove is formed among the first limiting plate 111, the second limiting plate 112 and the arc-shaped guiding rib 113. A hinge ear plate 211 is provided on the rotating shaft 21. A handle 212 is hinged to the hinge ear plate 211 through a pin shaft. A U-shaped clamping plate 213 is provided on the right door leaf at a position corresponding to the handle 212. The handle 212 can be rotated downward into the groove of the U-shaped clamping plate 213.

[0030] Make the sealing edge 23 of the right door leaf abut against the free end of the left door leaf, and close the left door leaf and the right door leaf. When the locking cam 22 is clamped in the clamping groove of the locking block 11, rotate the rotating shaft 21 to make the locking cam 22 rotate counterclockwise. During the rotation of the locking cam 22, push the right door leaf inward until the switch door 2 is closed. Then rotate the handle 212 downward to nest it in the groove of the U-shaped clamping plate 213. The locking structure of this switch door 2 is convenient to operate, improves the sealing performance of the switch door 2, and improves the secondary aging effect.
