Description

Technical Field

[0001] This utility model relates to the field of plastic film production technology, and in particular to a plastic film conveying device. Background Technology

[0002] Plastic film is a common and frequently used film. During the production of plastic film, a conveying device is needed to transport the film. However, during the transport process, the plastic film is easily contaminated with external dust, powder, and other dirt. If it is not cleaned before being rolled up, it will affect the performance and appearance of the plastic film.

[0003] Chinese patent CN220165362U discloses a plastic film conveying device, including a worktable. A first support frame is installed on the upper left and upper right sides of the worktable. A leveling device is installed on the upper middle of each of the first support frames. A second support frame is installed on the upper middle of the worktable, and a cleaning device is installed on the upper middle of the second support frame. A first hydraulic cylinder is installed at the rear of the upper part of the worktable, and a winding device is installed above the first hydraulic cylinder. This plastic film conveying device uses the second hydraulic cylinder on the leveling device to drive the mounting frame downwards. At this time, the first pressure roller on the mounting frame presses the plastic film firmly onto the second pressure roller, thus preventing the plastic film from shifting or wrinkling during conveying, improving the conveying efficiency. The cleaning device allows the cleaning brushes to clean both sides of the plastic film during conveying and winding, further improving the conveying quality.

[0004] The aforementioned plastic film conveying device cleans the surface of the plastic film by using cleaning brushes set on the upper and lower sides of the plastic film when conveying the plastic film. This cleaning method relies on the flow of the plastic film to achieve cleaning, but such cleaning cannot effectively remove the dust. At the same time, the dust adsorbed on the cleaning brushes will still fall onto the plastic film, resulting in poor cleaning effect of the plastic film. Utility Model Content

[0005] In order to solve the problem of poor dust removal effect of the above-mentioned plastic film conveying device when conveying plastic film, this utility model proposes a plastic film conveying device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a plastic film conveying device, including a base plate and a top plate, wherein guide rollers for conveying and guiding plastic film are fixed on the upper surface of the base plate near the left and right sides, and pressure rollers for pressing plastic film in conjunction with the guide rollers are fixed on the lower surface of the top plate near the left and right sides, and cleaning devices for cleaning surface dust of plastic film are fixed on the middle part of the upper surface of the base plate and the middle part of the lower surface of the top plate, and electric lifting rods fixedly connected to the base plate are fixed on the lower surface of the top plate near the four corners;

[0007] The cleaning device includes a dust collection box with an opening on one side. Multiple brush rollers arranged horizontally are installed inside the opening of the dust collection box, and multiple support plates arranged horizontally are fixed at the opening of the dust collection box.

A suction mechanism is fixed on the side of the dust collection box away from the opening, and the suction end of the suction mechanism is connected to the dust collection box.

[0008] As a preferred embodiment, the suction mechanism includes a suction box with an opening on one side facing the dust collection box, multiple mounting blocks fixed on both the front and rear sides of the suction box, and multiple fans blowing air outwards fixed on the front side of the suction box, with a removable filter plate installed inside the suction box near the front side.

[0009] As a preferred option, the filter plate is horizontally inserted into the inside of the air intake box, and a gap is left between the filter plate and the front side wall inside the air intake box.

[0010] As a preferred embodiment, the filter plate includes an insert plate, a groove is provided in the middle part of the insert plate, and a removable and washable filter cotton is installed inside the groove. The bottom surface of the groove is provided with evenly arranged air passage holes.

[0011] As a preferred embodiment, multiple fixing nails are fixed on the inner bottom surface of the groove, and the filter cotton has a sleeve hole for fitting onto the fixing nails.

[0012] As a preferred embodiment, the bottom inner surface of the dust collection box is provided with multiple air inlets arranged in a left-right pattern, and the side of the dust collection box away from the plastic film is fixed with multiple evenly distributed fixing posts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0027] like Figure 1 As shown, a plastic film conveying device includes a base plate 1 and a top plate 3. Guide rollers 6 for conveying and guiding plastic film are fixed on the upper surface of the base plate 1 near the left and right sides. Pressing rollers 2, which work with the guide rollers 6 to press the plastic film, are fixed on the lower surface of the top plate 3 near the left and right sides. The pressing rollers 2 work with the guide rollers 6 to flatten the plastic film and prevent wrinkles. Cleaning devices 4 for cleaning surface dust from the plastic film are fixed in the middle of the upper surface of the base plate 1 and the middle of the lower surface of the top plate 3. The cleaning devices 4 are used to clean dust from the plastic film. Electric lifting rods 5, which are fixedly connected to the base plate 1, are fixed on the lower surface of the top plate 3 near the four corners.

[0028] like Figure 2 As shown, the cleaning device 4 includes a dust collection box 43 with an opening on one side. Multiple brush rollers 41 arranged horizontally are installed inside the opening of the dust collection box 43. The brush rollers 41 are arranged longitudinally, and one end of each brush roller is connected to a motor that drives its rotation. Multiple support plates 42 arranged horizontally are fixed at the opening of the dust collection box 43. The multiple brush rollers 41 and support plates 42 are arranged alternately. A suction mechanism 45 is fixed on the side of the dust collection box 43 away from the opening, and the suction end of the suction mechanism 45 is connected to the dust collection box 43. The multiple brush rollers 41 inside the dust collection box 43 continuously rotate to clean the plastic film. Simultaneously, the dust collection box 43, driven by the suction mechanism 45, continuously suctions air to remove the cleaned dust. The rotating brush rollers 41 clean more thoroughly, and the suction of the dust collection box 43 effectively prevents dust from adhering to the brush rollers 41 and re-contaminating the plastic film, resulting in a better cleaning effect.

[0029] like Figure 3 As shown, the suction mechanism 45 includes a suction box 452 with an opening on one side facing the dust box 43. Multiple mounting blocks 451 are fixed on both the front and rear sides of the suction box 452. The mounting blocks 451 are fixed to the dust box 43 with screws to install and fix the suction box 452.

[0030] Multiple fans 453 that blow air outward are fixed to the front side of the suction box 452. The fans 453 blow air outward so that the suction box 452 can draw air in.

[0031] A removable filter plate 454 is installed inside the air intake box 452 near the front. The filter plate 454 is used to filter the air flowing through it. The removable filter plate 454 is easy to disassemble and clean. The filter plate 454 is horizontally inserted into the inside of the air intake box 452 to achieve the removable installation of the filter plate 454.

[0032] A gap is left between the filter plate 454 and the front side wall of the air suction box 452 so that the air will not flow through the filter plate 454 excessively when the fan 453 draws air, thus making the filter plate 454 filter more evenly.

[0033] like Figure 4 As shown, the filter plate 454 includes an insert plate 4541. A groove is provided in the middle part of the insert plate 4541, and a removable and washable filter cotton 4543 is installed inside the groove. The filter plate 454 uses the groove on the insert plate 4541 to install the filter cotton 4543. A plurality of fixing nails 4542 are fixed on the bottom surface of the inner side of the groove. The filter cotton 4543 has a sleeve hole 4545 that fits on the fixing nail 4542. The filter cotton 4543 is fitted onto the fixing nail 4542 through the sleeve hole 4545 to achieve installation and fixation.

[0034] The bottom surface of the groove is provided with evenly arranged air passage holes 4544, and ventilation is carried out through the air passage holes 4544 in the groove. The air passing through the air passage holes 4544 is filtered by the filter cotton 4543 for dust removal.

[0035] like Figure 5 As shown, the bottom inner surface of the dust collection box 43 is provided with multiple air inlets 431 arranged in a left-right manner. The multiple air inlets 431 are driven by the air collection box 452 to perform air suction. The side of the dust collection box 43 away from the plastic film is fixed with multiple evenly distributed fixing posts 44. The dust collection box 43 is fixed to the bottom plate 1 or the top plate 3 by the fixing posts 44.

[0036] In this embodiment, when conveying the plastic film, the guide rollers 6 on the left and right sides guide and convey the plastic film. At this time, the electric lifting rod 5 drives the top plate to descend, so that the pressure roller 2 presses the plastic film. Meanwhile, the dust collection box 43 on the upper side is close to the plastic film. At this time, multiple brush rollers 41 in the port of the dust collection box 43 continuously rotate to clean the plastic film. The dust collection box 43 continuously sucks air under the drive of the suction mechanism 45 to remove the cleaned dust, thereby completing the cleaning of the plastic film.

[0037] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
