[0027] In the structure, the staff puts the material into the inner wall of the material placing shell 3, and the material in the material placing shell 3 is conveyed from the inner wall of the discharging pipe 8 to the inner wall of the fixed shell 9. When the material falls onto the surface of the crushing rod 22, the controller 2 sends a signal, and the power output shaft of the motor 3 rotates after receiving the signal. The crushing rod 22 is driven to rotate by the motor 3, so that the material is crushed when the crushing rod 22 rotates, and the material is melted more quickly. Then the melted material is extruded by the extruder 4, and the material is conveyed from the inner wall of the communication pipe 10. The material is blown by the film blowing mechanism 11, so that the plastic appears to be inflated.
[0028] In a preferred embodiment: the inner wall of the placing rack 5 is rotationally connected with the winding roller one 12, the outer wall of the placing rack 5 is fixedly connected with the motor one 13, the power output shaft of the motor one 13 is fixedly connected with the rotating shaft 14, the outer wall of the rotating shaft 14 is fixedly connected with the rotating rod 15, the inner wall of the rotating rod 15 is rotationally connected with the winding roller two 16, the outer wall of the fixed plate 6 is fixedly connected with the motor two 17, the power output shaft of the motor two 17 is fixedly connected with the winding roller three 18, one end of the fixed rod 19 is fixedly connected with the outer wall of the fixed plate 6, and the other end of the fixed rod 19 is fixedly connected with the monitor 20.
[0029] In the structure, during the winding process of the plastic bag, the device controller 2 sends an instruction signal, and the power output shaft of the motor two 17 starts to rotate after receiving the signal. The rotating action drives the winding roller three 18 to wind the plastic bag by the motor two 17. At the same time, the winding roller three 18 rotates in linkage with the winding roller one 12 during the winding process of the plastic bag. When the monitor 20 detects that the plastic bag appears to be loose during the winding process, it sends a signal to the motor one 13. After receiving the signal, the power output shaft of the motor one 13 drives the rotating shaft 14 to rotate. The rotating action of the rotating shaft 14 further drives the rotating rod 15 to rotate, and the rotating action of the rotating rod 15 drives the winding roller two 16 to extrude the plastic bag, so that the plastic bag in the winding state is more compact. This process effectively avoids the wrinkles that may occur when winding the loose plastic bag, and realizes the automatic tensioning function of the plastic bag winding.
[0030] In a preferred embodiment: the protection component 7 includes a protection shell 701, a sliding groove 703 is provided on the outer wall of one end of the protection shell 701, a placement groove 706 is provided on the outer wall of the other end of the protection shell 701, the inner wall of the sliding groove 703 is slidably connected to the protection shell 2 702, the top of the protection shell 2 702 is fixedly assembled with a limiting plate 704, the outer wall of the protection shell 2 702 is fixedly assembled with a placement rod 705, the upper and lower ends of the placement rod 705 are both provided with a locking groove 707, the inner wall of the placement groove 706 is provided with a moving groove 708, the inner wall of the moving groove 708 is fixedly assembled with one end of a spring 709, and the other end of the spring 709 is fixedly assembled with a locking block 710.
[0031] In the above structure, during the film blowing process of the plastic bag, the operator applies pressure to the protective shell 2 702, causing the protective shell 2 702 to slide on the inner wall of the sliding groove 703. When the protective shell 2 702 pulls the placement rod 705 into the inner wall of the placement groove 706, the placement rod 705 immediately applies pressure to the positioning block 710, causing the positioning block 710 to move toward the inner wall of the moving groove 708 after being pressed. During this movement, the positioning block 710 also applies pressure to the spring 709. When the positioning block 710 is pressed, the spring 709 is pressed. After the placement rod 705 is fully embedded in the inner wall of the placement groove 706, the restriction on the spring 709 is released, and the spring 709 therefore releases its elastic potential energy and drives the locking block 710 to move toward the inner wall of the locking groove 707, thereby realizing the connection between the protective shell 1 701 and the protective shell 2 702. At the same time, the limiting plate 704 limits the protective shell 2 702 to prevent the protective shell 2 702 from falling off when sliding on the inner wall of the sliding groove 703, thereby ensuring that the plastic bag after film blowing is properly protected.

The protective component 7 is limited by placing the shell 1, and the protective shell 2 702 is limited by the limiting plate 704. When the protective shell 2 702 rotates to the end of the sliding groove 703, the limiting plate 704 will block the protective shell 2 702, so that the protective shell 2 702 will not fall off. When the locking block 710 is placed into the inner wall of the locking groove 707, the protective shell 1 701 and the protective shell 2 702 are connected.
[0034] In a preferred embodiment: the extruder 4, the motor one 13, the motor two 17, the monitor 20, the electromagnetic valve 25 and the motor three 21 are all electrically connected with the controller 2, and the rotating shaft 14 is rotationally connected with the inner wall of the placing rack 5.

[0036] In a preferred embodiment: the number of fixed rods 19 and monitors 20 is two, and the two fixed rods 19 and monitors 20 are respectively located on the outer wall of the fixed plate 6.
[0037] In the above structure, the two fixed rods 19 and monitors 20 are used to detect the plastic during winding, and a signal will be sent when the plastic during winding is loose.
[0038] Working principle: during the winding process of the plastic bag, the controller 2 sends a signal to drive the motor two 17 to rotate after receiving the signal, and the motor two 17 drives the winding roller three 18 to wind the plastic bag, while the winding roller three 18 drives the winding roller one 12 to rotate, when the monitor 20 finds that the plastic bag is loose during winding, it will send a signal to the motor one 13, which drives the power output shaft of the motor one 13 to rotate, and the rotating shaft 14 drives the rotating rod 15 to rotate, and then the rotating rod 15 pushes the winding roller two 16 to extrude the plastic, to ensure that the plastic in the winding state is more compact, to avoid wrinkles caused by looseness, so as to realize the automatic tensioning function, during the blowing process of the plastic bag, the worker applies pressure to the protective shell two 702 to make it move in the inner wall of the sliding groove 703, when the protective shell two 702 drives the placing rod 705 to be positioned in the inner wall of the placing groove 706, the placing rod 705 applies pressure to the clamping block 710 to make it move to the inner wall of the moving groove 708, and the clamping block 710 applies pressure to the spring 709 during the movement, once the placing rod 705 completely enters the inner wall of the placing groove 706, the spring 709 is released, and its elastic potential energy is released, the spring 709 then pushes the clamping block 710 to move to the inner wall of the clamping groove 707, to realize the connection between the protective shell one 701 and the protective shell two 702, at the same time, the limiting plate 704 limits the protective shell two 702 to prevent it from moving out of the sliding groove 703, to ensure effective protection of the plastic bag behind the eardrum.
