The rack 21 is fixed on the main frame 1; the pair of guide rails 22 are fixed on the main frame 1 and are respectively located on both sides of the rack 21; the lifting frame 23 is set on the pair of guide rails 22 for guiding sliding, and the lifting frame 23 is connected to the heating module; the first driver 24 is connected to the lifting frame 23, and the first driver 24 is a motor; the first gear 25 is sleeved on the output end of the first driver 24, and the first gear 25 is meshed with the rack 21. By controlling the operation of the first driver 24, the first gear 25 can be driven to rotate, and then the gear can be moved along the rack 21, so that the lifting frame 23 can slide on the pair of guide rails 22.

[0047] Specifically, Figures 1 - 2 As shown, the heating module is connected to the output end of the lifting module, and is lifted and lowered for heating under the drive of the lifting module. The heating module comprises: a connecting platform 31, a heating cylinder 32 and a heating unit. The connecting platform 31 is connected to the output end of the lifting module, and a clearance hole is provided on the connecting platform 31 to facilitate the passage of the steel cylinder; the heating cylinder 32 is arranged at the bottom of one end of the connecting platform 31, and a heating cavity is provided inside the heating cylinder 32, and a plurality of heating holes 321 are provided on the inner wall of the heating cylinder 32; the heating unit is connected to the connecting platform 31 and the heating cylinder 32, and is used to convey hot air into the heating cavity, and finally discharged from a plurality of heating holes 321 to achieve thermal plastic sealing of the plastic film on the surface of the steel cylinder.

[0048] Further, if Figures 1 - 2As shown, the heating unit includes: a blower 331, at least one air duct 332, and at least one heater 333. The blower 331 is disposed on the connection table 31; the input end of at least one air duct 332 is connected to the output end of the blower 331, and the output end of at least one air duct 332 communicates with the heating chamber; at least one heater 333 is respectively communicated with at least one air duct 332. The blower 331 conveys air into the air duct 332, and after being heated by the heater 333, hot air is formed and transferred to the heating chamber.

[0049] Further, as Figures 1 - 2 shown, the connection table 31 and the heating cylinder 32 are connected by an annular connecting piece 34.

[0050] Specifically, as Figure 1 、 3 shown, the placing table 4 is located on one side of the main body frame 1. Both ends of the top of the placing table 4 are provided with two placing areas 41 for placing cylinders to be plastic-sealed.

[0051] Specifically, as Figure 1 、 3 shown, the rotating module is connected to the placing table 4 and drives the placing table 4 to rotate. The rotating module includes: a base 51, a support shaft 52, a second gear 53, a second driver 54, and a third gear 55.

By controlling the operation of the second driver 54, the third gear 55 can be driven to rotate on the second gear 53, and thus the placing table 4 rotates along the support shaft 52.

[0052] Further, as Figure 4 、 5 shown, a heat plastic-sealing mechanism for the plastic film on the surface of a cylinder according to an embodiment of the present utility model further includes: four clamping cylinders 61 and four clamping claws 62.

When the temperature of the heater rises to the specified temperature, the lifting module drives the heating module to descend, and hot air is discharged from a number of heating holes 321 to start heat shrink packaging. After the heat shrink packaging is completed, the clamping cylinder is loosened. While heat shrink packaging, place another steel cylinder in the other placement area 41 and put on a bag. After the heat shrink packaging is completed, the rotating module rotates, the new steel cylinder enters the heat shrink packaging processing station, the heat - shrink - packaged steel cylinder returns to the loading station, the steel cylinder is taken down manually, and then a new steel cylinder is put on and a bag is put on. Wait for the completion of heat shrink packaging. Repeat the cycle.

This breakthrough not only greatly shortens the production cycle and reduces manual intervention, but also ensures the uniformity, sealing performance and aesthetics of the heat shrink packaging layer on the surface of the steel cylinder, achieving a qualitative leap in surface quality. In addition, the automated process also enhances the stability and reliability of the production line, reduces errors and defective product rates caused by human factors, and brings a more efficient, more environmentally friendly and more economical production solution to the steel cylinder manufacturing industry.
