[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-2 , an embodiment provided by the utility model:

[0016] A forming device for transparent plastic bagging includes a fixed base 1, a support rod 10 and a reel 12. The front side of the fixed base 1 is fixedly connected to a motor 2, the bottom of the output shaft of the motor 2 is fixedly connected to a threaded rod 3, the external thread of the threaded rod 3 is connected to a movable plate 4, the bottom of the movable plate 4 is fixedly connected to a heater 5, and the bottom of the heater 5 is fixedly connected to a metal heat conducting plate 6.

[0017] Furthermore, the fixed seat 1 is fixedly connected to the motor 2 to maintain the stability of the motor 2. The output shaft of the motor 2 is fixedly connected to the threaded rod 3, so that the motor 2 can drive the threaded rod 3 to rotate after starting. The threaded rod 3 is threadedly connected to the movable plate 4, and the limit rod 9 is slidingly connected to the movable plate 4, so that when the threaded rod 3 rotates, it can drive the movable plate 4 to move up and down.

[0018] Furthermore, the movable plate 4 is fixedly connected to the heater 5 , so that when the movable plate 4 moves, the heater 5 can be driven to move up and down, and the heater 5 plays a role in heating the metal heat conducting plate 6 .

[0019] Furthermore, the first limiting block 7 is rotatably connected to the threaded rod 3 to maintain the stability of the threaded rod 3 , and the second limiting block 8 is fixedly connected to the limiting rod 9 to maintain the stability of the limiting rod 9 .

[0020] Furthermore, the support rod 10 is fixedly connected to the support plate 11 to maintain the stability of the support plate 11 . The support plate 11 and the heated metal heat conducting sheet 6 can extrude the double-layer plastic film 13 to seal the double-layer plastic film 13 .

[0021] Furthermore, the reel 12 serves to reel in and unreel the double-layer plastic film 13 .

[0022] Working principle: The heater 5 heats the metal thermal conductive sheet 6, the motor 2 drives the threaded rod 3 to rotate, and the threaded rod 3 drives the movable plate 4, the heater 5 and the metal thermal conductive sheet 6 to move downward, so that the heated metal thermal conductive sheet 6 and the support plate 11 squeeze the double-layer plastic film 13, so that the double-layer plastic film 13 adheres to each other and seals, and the winder 12 winds and unwinds the double-layer plastic film 13, thereby driving the double-layer plastic film 13 to slide on the top of the support plate 11. During the process of the heated metal thermal conductive sheet 6 moving downward and contacting the plastic film 13, the winder 12 stops operating. After a sealing action is completed, the metal thermal conductive sheet 6 moves up and away from the plastic film 13, and the winder 12 continues to operate to drive the double-layer plastic film 13 to move. The degree of automation is high, which improves the processing and forming efficiency of the transparent plastic sleeve.
