[0021] In the above structure, through the arrangement of the mounting base 1, the main body 5, the movable base 6, the motor 7, and the threaded rod 8 structure, during the operation of the film blowing machine, the user can rotate the threaded rod 8 by operating the motor 7, so that the movable block 13 can slide along the inner wall of the adjustment groove, so that the position of the tensioning shaft 14 can be adjusted, and then the user can use the movement of the tensioning shaft 14 to tension the main body 5, thereby ensuring the tension of the main body 5 during the transportation process and avoiding wrinkles or even folds of the main body 5 during the transportation process.

[0022] In a preferred embodiment: a positioning plate is fixedly mounted on the top of the mounting seat 1, and the outer wall of the positioning plate is rollingly connected to the outer wall of the roller shaft 1 2.

[0023] In the above structure, by setting the positioning plate and roller 1 2 structure, when the main body 5 is manufactured, it is guided and conveyed by roller 1 2, so that the main body 5 can contact the tensioning shaft 14 and roller 2 respectively, thereby realizing the effect of fully automatic conveying of the main body 5, thereby improving the automation of the film blowing machine.

[0024] In a preferred embodiment: the outer wall of the main body 5 is also rollingly connected to the outer wall of the tensioning shaft 14, the outer wall of the mounting seat 1 is fixedly equipped with a straight plate, the outer wall of the straight plate is rotatably connected to roller shaft 2, and the outer wall of roller shaft 2 is rollingly connected to the outer wall of the main body 5.

[0025] In the above structure, by setting the roller shaft 2 and the straight plate structure, the straight plate is used to limit the roller shaft 2, thereby ensuring that the roller shaft 2 can rotate stably, so that the main body 5 can move stably in the subsequent conveying process, further improving the conveying effect of the film blowing machine on the main body 5.

[0026] In a preferred embodiment, the inner wall of the slide groove 3 is slidably connected to the outer walls of the slide bar 12 and the moving block 13 respectively, and the slide bar 12 and the moving block 13 are both made of galvanized iron metal.

[0027] In the above structure, by setting the slide bar 12 and the moving block 13 structure, the movement of the slide bar 12 and the moving block 13 is utilized to make the tensioning shaft 14 follow the movement of the moving block 13, so that the tensioning shaft 14 can tension the main body 5, which is convenient for the user to adjust the tension of the main body 5. The galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the wear of the slide bar 12 and the moving block 13 during the movement process, thereby extending the service life of the device.

[0028] In a preferred embodiment, there are two rotating wheels 10 , and the two rotating wheels 10 are connected to each other via a transmission belt 11 .

[0029] In the above structure, by setting the rotating wheel 10 and the transmission belt 11 structure, when the motor 9 drives one rotating wheel 10 to rotate, the transmission belt 11 is used to transmit the other rotating wheel 10 to rotate synchronously, thereby achieving the effect of synchronous rotation of the two screw rods 4 and allowing the tensioning shaft 14 to move smoothly, thereby improving the energy utilization rate of the film blowing machine.

[0030] Working principle: After the user assembles the device, the main body 5 is first transported by roller 1 2. At this time, the main body 5 is transported with the cooperation of roller 2 and roller 1 2, and the main body 5 is tensioned with the tensioning shaft 14, so as to ensure that the main body 5 will not be wrinkled or even folded during the transportation process, thereby improving the transportation effect of the device on the main body 5. During the transportation process, the movement of the movable seat 6 is used to adjust the distance between the tensioning shaft 14 and roller 2, so that the user can adjust the transportation angle of the main body 5, and then the user can roll and collect the main body 5. The movement of the movable seat 6 drives the two screws 4 to rotate synchronously through a single motor 9, thereby improving the energy utilization rate of the device.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
