[0035] See also Figure 1-Figure 4 As shown, this embodiment is a highly uniform PE protective film blowing device, comprising:

[0036] A main body component, the main body component includes an operating frame 11;

[0037] The operating frame 11 is used to place other components;

[0038] A protection assembly, the protection assembly includes a set of ground rails 21, a moving frame 22, a cylinder 23, and a connecting rod 24;

[0039] The ground rails 21 are fixed on the ground, the moving frame 22 is slidably connected to the top of the ground rail 21, the cylinder 23 is fixed on the upper inner side of one side of the moving frame 22, and the connecting rod 24 is slidably connected to the inside of one end of the cylinder 23;

[0040] The ground rail 21 is located between the tractor 12 and the operating frame 11 and is fixed on the ground. The mobile frame 22 is used to place other components. The cylinder 23 is used to start the connecting rod 24. The cylinder 23 is fixed to the upper right side of the left mobile frame 22. The connecting rod 24 is slidably connected to the right side of the cylinder 23.

[0041] A protective box 25 is fixedly connected to the outer end of the connecting rod 24, a limit box 26 is fixedly connected to the upper inner side of the moving frame 22 on the other side, and a support rod 27 is fixedly connected to one side of the moving frame 22;

[0042] The protection box 25 can protect the film exposed to the air, the limit box 26 is fixed on the upper left side of the right moving frame 22, and the support rod 27 is fixed on the center of the rear side of the moving frame 22, and the support rod 27 supports the moving frame 22;

[0043] A cross bar 28 is fixedly connected to the lower side of the operating frame 11, and the outer end of the support rod 27 is adsorbed on the cross bar 28. A group of moving plates 251 are clamped inside the outer end of the protection box 25, and a group of springs 252 are fixedly connected to the inner end of the moving plate 251. The other end of the spring 252 is fixedly connected to the inside of the protection box 25.

[0044] The cross bar 28 is fixed to the lower front side of the operating frame 11. The cross bar 28 is used to be adsorbed and connected with the rear end of the support rod 27. The rear side of the support rod 27 is magnetic. When the moving frame 22 is moved, the support rod 27 is adsorbed with the cross bar 28. When the moving frame 22 moves, the support rod 27 is not adsorbed with the cross bar 28. A spring 252 and a moving plate 251 are arranged inside the right side of the protective box 25 to facilitate the moving plate 251 to protect films of different sizes. There are four springs 252 in total.

[0045] Working principle:

[0046] Before the assembly is used, the mobile frame 22 is located in front of the left and right sides of the operating frame 11. Since the ground rail 21, the mobile frame 22 and the device itself are electrically connected, when the assembly is used, the mobile frame 22 is driven by electricity, so that the mobile frame 22 moves relatively on the ground rail 21, and at this time, the support rod 27 moves accordingly;

[0047] When the moving frame 22 moves relatively, the cylinder 23 is started, and the cylinder 23 drives the connecting rod 24 to extend, so that the connecting rod 24 drives the protective box 25 to extend. When the PE protective film is completely located in the protective box 25, the right end of the moving plate 251 is engaged with the limit box 26, and at the same time, the spring 252 is compressed in the protective box 25, and the spring 252 buffers the force during movement;

[0048] At this time, the moving frame 22 stops moving. Since the rear end of the support rod 27 is magnetic, the rear end of the support rod 27 is adsorbed together with the cross bar 28, and the support rod 27 provides auxiliary supporting force for the moving frame 22.

[0049] At this time, the film is completely located in the protective box 25, and the protective box 25 separates the film from the outside world;

[0050] In the above steps, the film is separated from the outside world through the interaction between the protection box 25 and the limit box 26.

[0051] See also Figure 1-Figure 3 , Figure 5 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0052] Limiting components;

[0053] The limiting assembly includes a square block 31 and a movable plate 32;

[0054] The square block 31 is movably connected to the edge of one side below both ends of the operating frame 11, and one end of the square block 31 is fixedly connected to a movable plate 32;

[0055] The square block 31 is movably connected to the front edge of the lower left and right sides of the operating frame 11. The square block 31 is used to connect other components with the lower side of the operating frame 11. The movable plate 32 is fixed to the front end of the square block 31. The movable plate 32 limits the movable frame 22.

[0056] The outer end of the movable plate 32 passes through a limit rod 33, and a movable shaft 34 is movably connected to the outer side of the connection between the square block 31 and the operating frame 11;

[0057] A limiting groove 35 is provided at the bottom of one side of the moving frame 22;

[0058] When the moving frame 22 moves to the inside of the movable plate 32, the limiting rod 33 passes through the front end of the movable plate 32 and is inserted into the limiting groove 35, so that the limiting rod 33 limits the moving frame 22 inside the movable plate 32. The limiting groove 35 is provided at the lower front side of the moving frame 22.

[0059] The main assembly also includes a tractor 12, a guide 13, and a film blowing device 14;

[0060] The tractor 12 is placed on one side of the operating frame 11, the guide 13 is fixed on the top of the operating frame 11, and the film blowing device 14 is placed below the operating frame 11;

[0061] The tractor 12 is used to tract and stretch the film. The tractor 12 is placed at the front and lower side of the operating frame 11. The guide 13 is used to guide the direction of the film. The film blowing device 14 blows the film.

[0062] Working principle:

[0063] Before the assembly is not used, the movable plate 32 partially overlaps with the operating frame 11. When the assembly is used, the movable plate 32 is rotated by hand, and the movable plate 32 is rotated upward through the square block 31 and the movable shaft 34. The movable plate 32 is rotated to be perpendicular to the bottom of the operating frame 11, and then it can stop.

[0064] At this time, the movable frame 22 is operated to move to the inner side of the movable plate 32, and then the limiting rod 33 is held by hand, and the limiting rod 33 is passed through the front end of the movable plate 32, and the rear end of the limiting rod 33 is inserted into the limiting groove 35, and the limiting rod 33 is rotated at the same time, so that the limiting rod 33 limits the movable frame 22 inside the movable plate 32, so as to prevent the movable frame 22 from shaking after stopping the movement;

[0065] The above steps can improve your functionality.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
