Description

Technical Field

[0001] This utility model relates to the field of air cushion film production technology, specifically to an air cushion film rolling equipment. Background Technology

[0002] Air cushion film is a packaging material made of polyethylene as the main raw material. It is plasticized and extruded into a film through an extruder, and then a bubble layer is formed in the middle of the film through a special process. Air cushion film has good cushioning performance, moisture-proof performance and flexibility. It is widely used in the field of product packaging and can effectively protect the packaged products from damage such as collision and squeezing during transportation and storage.

[0003] Existing technologies often have the following problems when used:

[0004] To prevent loosening during the production and winding process of air cushion film, an elastic extrusion mechanism is usually installed to fully compress and limit the air cushion film during winding. However, the elastic extrusion mechanism is prone to relative friction with the air cushion film during winding, resulting in wear on the surface of the air cushion film. In addition, one end of the air cushion film is usually fixed at the beginning of winding to facilitate the winding operation. However, the initial fixing of the air cushion film will cause a certain indentation at its end, resulting in damage to part of the air cushion film and affecting the production quality of the air cushion film. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides an air cushion film rolling device that effectively solves the problems in existing technologies where the elastic extrusion mechanism used for rolling and limiting the air cushion film generates relative friction with the air cushion film, resulting in wear on the surface of the air cushion film, and where indentations are generated at the ends of the air cushion film during initial fixing, causing damage to some parts of the air cushion film and affecting the production quality of the air cushion film.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an air cushion film rolling device, comprising:

[0008] A base plate, on the upper surface of which a lateral support plate is fixedly connected, and a rotating shaft is rotatably connected through the side wall of the lateral support plate, and a take-up roller and two protective discs are fixedly connected to the outer peripheral wall of the rotating shaft;

[0009] A winding limiting assembly includes two sliding frames fixedly connected to the upper surface of a base plate. A lifting rod is slidably connected through the upper end of each of the two sliding frames. A rotating frame is fixedly connected to the upper end of each of the two lifting rods. A rotating rod is rotatably connected between the two rotating frames. A limiting roller is fixedly connected to the outer peripheral wall of the rotating rod. A rotary motor is fixedly installed on the outer wall of one of the rotating frames. The output end of the rotary motor is fixedly connected to the end of the rotating rod.

[0010] One of the protective discs has a non-marking fixing component fixedly installed on its outer wall.

[0011] Furthermore, both the take-up roller and the limit roller adopt a hollow structure, and several air chambers are formed between the two protective discs and the inside of the take-up roller.

[0012] Furthermore, a low-speed motor is fixedly installed on the outer wall of the lateral support plate, and the output end of the low-speed motor is fixedly connected to the end of the rotating shaft.

[0013] Furthermore, the winding limiting assembly also includes a tension spring fitted onto the outer wall of the lifting rod, with its two ends fixedly connected to the upper end of the sliding frame and the lower end of the lifting rod, respectively.

[0014] Furthermore, the non-marking fixing component includes an air pump fixedly installed on the outer wall of the protective disc, a plurality of T-shaped connecting pipes are connected to the protective disc, the air inlet end of the T-shaped connecting pipe is connected to a plurality of air chambers, the air outlet end of the T-shaped connecting pipe is connected to the air extraction end of the air pump, and a plurality of ventilation holes are provided on the outer peripheral wall of the take-up roller.

[0015] Furthermore, both the take-up roller and the limit roller are made of aluminum alloy, and thin silicone anti-slip pads are fixedly connected to the outer surfaces of both the take-up roller and the limit roller.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention includes a winding limiting component. During the winding process of driving the winding roller to rotate and winding the air cushion film, the elastic potential energy of the tension spring itself can be used to push the lifting rod, so that the limiting roller can always be close to and squeeze the air cushion film, thereby limiting the air cushion film during winding, preventing the air cushion film from becoming scattered during winding, and ensuring the neatness of the air cushion film winding. At the same time, the limiting roller can be driven to rotate, so that the rotation of the limiting roller can be synchronized with the winding of the air cushion film, thereby reducing the relative friction between the limiting roller and the air cushion film and preventing wear on the surface of the air cushion film.

[0018] The non-marking fixing component of this utility model uses an air pump to discharge the air in the air chamber through a T-shaped connecting pipe, so that a negative pressure environment can be formed at several air holes on the take-up roller, so that the end of the air cushion film can be tightly adsorbed to the outer surface of the take-up roller, thereby achieving non-marking fixing of the air cushion film, thus avoiding indentation on the air cushion film, further preventing damage to the air cushion film, and helping to ensure the production quality of the air cushion film.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 4A cushion film rolling device includes a base plate 1 and a winding limiting assembly: a lateral support plate 2 is fixedly connected to the upper surface of the base plate 1, a rotating shaft is rotatably connected through the side wall of the lateral support plate 2, a winding roller 3 and two protective discs 4 are fixedly connected to the outer peripheral wall of the rotating shaft, the winding roller 3 has a hollow structure, and several air chambers 10 are formed between the two protective discs 4 and the interior of the winding roller 3; a low-speed motor 11 is fixedly installed on the outer wall of the lateral support plate 2, and the output end of the low-speed motor 11 is fixedly connected to the end of the rotating shaft; the winding limiting assembly includes two sliding frames 5 fixedly connected to the upper surface of the base plate 1, and a lifting rod 6 is slidably connected through the upper end of each of the two sliding frames 5. Two lifting rods 6 are fixedly connected to the upper ends of rotating frames 7, and rotating rods are rotatably connected between the two rotating frames 7. Limiting rollers 8 are fixedly connected to the outer periphery of the rotating rods. The take-up rollers 3 and the limiting rollers 8 are both made of aluminum alloy, and thin silicone anti-slip pads are fixedly connected to the outer surfaces of the take-up rollers 3 and the limiting rollers 8. The limiting rollers 8 have a hollow structure. A rotary motor 9 is fixedly installed on the outer wall of one of the rotating frames 7. The output end of the rotary motor 9 is fixedly connected to the end of the rotating rod. The take-up limiting assembly also includes a tension spring 12 fitted on the outer wall of the lifting rods 6. The two ends of the tension spring 12 are fixedly connected to the upper end of the sliding frame 5 and the lower end of the lifting rods 6, respectively.

[0028] The low-speed motor 11 drives the rotating shaft and the take-up roller 3 to rotate, thereby winding the air cushion film. During this process, the elastic potential energy of the tension spring 12 can be used to push the lifting rod 6, so that the limiting roller 8 at the upper end of the lifting rod 6 can always stick to and squeeze the air cushion film, so as to limit the air cushion film during winding, avoid the air cushion film from becoming scattered during winding, and ensure the neatness of the air cushion film winding. At the same time, the rotating motor 9 can drive the limiting roller 8 to rotate, so that the rotation of the limiting roller 8 can be synchronized with the winding of the air cushion film, thereby reducing the relative friction between the limiting roller 8 and the air cushion film and avoiding wear on the surface of the air cushion film.

[0029] Reference Figure 1 , Figure 3 and Figure 4 One of the protective discs 4 has a non-marking fixing component fixedly installed on its outer wall. The non-marking fixing component includes an air pump 13 fixedly installed on the outer wall of the protective disc 4. Several T-shaped connecting pipes 14 are connected to the protective disc 4. The air inlet end of the T-shaped connecting pipe 14 is connected to several air chambers 10. The exhaust end of the T-shaped connecting pipe 14 is connected to the air suction end of the air pump 13. Several ventilation holes 15 are opened on the outer peripheral wall of the take-up roller 3.

[0030] The air pump 13 can be used to discharge the air in the air chamber 10 through the T-shaped connecting pipe 14, so that a negative pressure environment can be formed at several air holes 15 on the take-up roller 3, so that the end of the air cushion film can be tightly adsorbed to the outer surface of the take-up roller, achieving a traceless fixation of the air cushion film, thereby avoiding indentation on the air cushion film, further preventing damage to the air cushion film, and helping to ensure the production quality of the air cushion film.

[0031] The working principle of this utility model is as follows:

[0032] 1. In use, fix the end of the air cushion film to be rolled onto the outer surface of the take-up roller 3, and start the low-speed motor 11 and the rotary motor 9. The low-speed motor 11 drives the rotating shaft and the take-up roller 3 to rotate to roll up the air cushion film. During this process, the elastic potential energy of the tension spring 12 can be used to push the lifting rod 6, so that the limiting roller 8 at the upper end of the lifting rod 6 can always stick to and squeeze the air cushion film to limit the air cushion film during winding, avoid the air cushion film from being rolled up messily, and ensure the neatness of the air cushion film winding. At the same time, the rotary motor 9 can drive the limiting roller 8 to rotate, so that the rotation of the limiting roller 8 can be synchronized with the winding of the air cushion film to reduce the relative friction between the limiting roller 8 and the air cushion film and avoid wear on the surface of the air cushion film.

[0033] 2. During the air cushion film winding process, the air pump 13 can be controlled to operate simultaneously. The air pump 13 is used to discharge the air in the air chamber 10 through the T-shaped connecting pipe 14. At this time, the air pressure inside the winding roller 3 gradually decreases, while the air pressure outside the winding roller 3 is relatively high. A certain pressure difference is generated at the vent 15, that is, a negative pressure environment can be formed at several vent 15 on the winding roller 3, so that the end of the air cushion film can be tightly adsorbed onto the outer surface of the winding roller, thereby achieving a traceless fixation of the air cushion film. This avoids indentation on the air cushion film and further avoids damage to the air cushion film, which is conducive to ensuring the production quality of the air cushion film.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
