[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] like Figure 1 As shown, the present application provides a packaging film forming device, including a frame 1, a film blowing assembly 3 is arranged below the frame 1, and the film blowing assembly 3 is used for film blowing forming processing of the packaging film;

[0027] like Figure 1-Figure 3 As shown, the film blowing assembly 3 is used to melt the plastic raw material and then perform the film blowing molding operation. The film blowing assembly 3 is a prior art, such as the patent with publication number CN108908917B, and the specific structure and principle are not described in detail here;

[0028] At the same time, a grabbing assembly 2 is fixedly installed on the frame 1, and the grabbing assembly 2 is used to deliver the packaging film after the film blowing to the top of the frame 1 to ensure subsequent processing;

[0029] The grabbing assembly 2 includes a support frame 23 fixedly mounted on the frame 1, a motor 26 fixedly mounted on the support frame 23, a screw rod 27 fixedly mounted on the output end of the motor 26, and a mounting seat 21 threadedly mounted on the screw rod 27, and two sets of guide rails 25 fixedly mounted on the support frame 23, sliders 24 slidably arranged on the two sets of guide rails 25, and the two sets of sliders 24 are fixedly mounted on the mounting seat 21 together, and a grabbing manipulator 22 is fixedly mounted on the mounting seat 21;

[0030] At the same time, a plurality of conveying rollers 4 are fixedly installed above the frame 1, and the plurality of conveying rollers 4 can be driven by a motor to convey the packaging film;

[0031] A plurality of winding rollers 6 are arranged on one side of the frame 1, and the plurality of winding rollers 6 can be driven by a motor to perform a winding operation on the packaging film;

[0032] In summary, in the initial state of packaging film production, the raw material is fed into the film blowing assembly 3 for film blowing forming operation, and then the staff tightens and pulls out the packaging film from the outlet of the film blowing assembly 3, and then fixes the packaging film through the grabbing manipulator 22, and then the packaging film is sent to the top of the frame 1 through the grabbing assembly 2, and the staff takes the packaging film from the top of the frame 1 and puts it on the conveying roller 4 and the winding roller 6 in turn, and then the packaging film production can be carried out, the raw material is blown into film by the film blowing assembly 3, and then the packaging film is wound up by the cooperation of the conveying roller 4 and the winding roller 6;

[0033] In the above implementation process, when the packaging film is rolled up, no device for cooling the packaging film is provided, which results in that the adhesive between the base films is not fully cross-linked and cured, the cohesive force is small, and relative sliding is easy to occur. In order to solve this problem, an air cooling component 5 is installed on the frame 1, and the air cooling component 5 is used for cooling the packaging film. Specifically:

[0034] like Figure 2 and Figure 4 As shown, the air cooling assembly 5 includes two groups of fixed blocks 52 fixedly mounted on the frame 1, and the two groups of fixed blocks 52 are rotatably mounted with rotating rods (not shown in the figure), one end of one group of rotating rods is fixedly sleeved with a worm gear 53, and a worm 55 is meshingly connected to the worm gear 53, the bearing of the worm 55 is mounted on the fixed block 52, and a handle 54 is fixedly mounted on the worm 55, and a connecting block 56 is fixedly mounted between the two groups of rotating rods, and a fan group 51 is fixedly mounted between the two groups of connecting blocks 56;

[0035] When the packaging film is transported and rolled up, the fan group 51 is turned on to perform air cooling on the packaging film to ensure the production quality of the packaging film. It should be noted that the air cooling component 5 can adjust the position of the fan group 51 according to the actual transportation path of the packaging film. When the position of the fan group 51 needs to be adjusted, the worm 55 is rotated by the handle 54, thereby driving the worm wheel 53 to rotate, thereby driving the rotating rod and the connecting block 56 to rotate, thereby driving the fan group 51 to rotate, and the worm 55 and the worm wheel 53 have a self-locking function to ensure that the position of the fan group 51 is fixed.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
