Description

Technical Field

[0001] The utility model relates to the technical field of OPP protective film processing, in particular to an adjustable OPP protective film coating device. Background Art

[0002] OPP protective film is a plastic film made of OPP as the base material, coated with acrylic glue on one side and attached with a release film. It is mainly used for surface protection during product transportation, as well as protection of various plastic parts such as plastic casings and keyboards.

[0003] Coating refers to applying a thin layer of plastic in liquid or powder form on the surface of fabrics, paper, metal foil or plates for the purpose of corrosion protection, insulation, decoration, etc. When processing OPP protective film, it is necessary to coat the OPP protective film to form a protective layer on the surface of the OPP protective film to effectively prevent the OPP protective film from being scratched and worn.

[0004] The patent with the patent authorization announcement number CN207430638U discloses a protective film coating device, including a body, an oven arranged on the body, a reeling unit, a printing unit and a coating unit sequentially mounted at the oven, the body is provided with a second oven above the oven, and the second oven is connected to the oven by a flipping mechanism that can flip the protective film. Although the above patent can dry both sides of the protective film by setting up an oven and a second oven, there are still some shortcomings in actual use. For example, when the scraper scrapes off the excess adhesive, since the scraper is set in a fixed position between the first guide roller and the drying box, it can only scrape off a certain amount of adhesive, resulting in the protective film surface can only be coated with a single thickness of adhesive layer, which cannot meet the coating requirements of protective films of different specifications, reducing the applicability of the equipment.

[0005] Therefore, an adjustable OPP protective film coating device is particularly needed to solve the problems existing in the prior art. Utility Model Content

[0006] In order to overcome the disadvantage that the existing patented scraper is set in a fixed position between the first guide roller and the drying box, so it can only scrape off a certain amount of adhesive, resulting in only a single thickness of adhesive layer being coated on the surface of the protective film, thereby failing to meet the coating requirements of protective films of different specifications and reducing the applicability of the equipment, the utility model provides an adjustable OPP protective film coating device.

[0009] Optionally, it also includes a slide rail, a slider and a motor. The slide rail is fixedly connected to the left front side of the lower part of the base, and the slider is slidably connected to the upper part of the slide rail. The motor is installed on the slider, and the output shaft of the motor is clamped with the winding roller. The motor is operated to make the winding roller rotate to wind up the coated OPP protective film.

[0010] Optionally, it also includes a connecting rod, a collection frame and a handle.

[0027] See also Figure 1-Figure 2 and Figure 4-Figure 5As shown, it also includes a connecting rod 12, a collection frame 10, a handle 11 and a limit plate 13. The middle side of the lower part of the base 1 is connected to the front and rear distributed connecting rods 12 by bolts, and the left and right distributed collection frames 10 are placed between the two connecting rods 12.

[0030] First, the staff puts the feeding roller 2 with the OPP protective film wound on the right part of the base 1, pulls one end of the OPP protective film from the feeding roller 2, passes the OPP protective film between the two adjusting rollers 3 after pulling it out, so that the OPP protective film is wound on the lower adjusting roller 3, and then passes the OPP protective film between the two heating tubes 15 and winds it on the winding roller 20. At this time, the OPP protective film is located below the unloading box 8 and the scraper 9, and contacts with the auxiliary rollers Ⅰ7 and Ⅱ16. Then, pinch the first knob 4 by hand and turn the first screw 5 to move the lower adjusting roller 3 to the right to a suitable position, so as to tighten the OPP protective film to a suitable degree to prevent the OPP protective film from loosening and affecting the coating effect, and then use the hand to Pinch the second knob 902 and rotate the second screw 901. After the scraper 9 moves downward to a suitable position, stop rotating the second screw 901 to adjust the distance between the scraper 9 and the upper surface of the OPP protective film, so that the scraper 9 can scrape off an appropriate amount of adhesive according to the coating thickness requirement of the OPP protective film, thereby improving the applicability of the device. The staff pours the adhesive into the discharge box 8, so that the adhesive flows downward to the upper surface of the OPP protective film, and then turns on the motor 17 through the controller 21. The output shaft of the motor 17 rotates to drive the winding roller 20 to rotate, so that the winding roller 20 starts to wind up the OPP protective film, and then pulls the OPP protective film to move to the left. The scraper 9 scrapes off the excess adhesive on the upper surface of the OPP protective film. A proper amount of adhesive is left on the upper surface of the OPP protective film to form a protective layer. The staff turns on the heating tube 15 through the controller 21, so that when the OPP protective film moves to the left and passes through the heating tube 15, the two heating tubes 15 run to dry the upper and lower surfaces of the OPP protective film at the same time, so as to achieve a good drying effect, which is conducive to the winding roller 20 to wind up the dried OPP protective film. During the coating process, the scraped excess adhesive flows down from the upper surface of the OPP protective film and then falls into the collection frame 10 for centralized collection, so as to facilitate recycling. When the left collection frame 10 is full of adhesive, the staff removes the left collection frame 10 from the two connecting rods 12 and places it at a suitable position at the lower part of the base 1. The limiting plate 13 contacts, and the limiting plate 13 limits the collection frame 10 on the left to the lower part of the base 1, and then pushes the collection frame 10 on the right to move to the left, so that it is located under the discharge box 8 and continues to collect the flowing adhesive. When the OPP protective film is coated, the staff turns off the motor 17 and the heating tube 15 through the controller 21, and then pulls the slider 18 forward to disengage the output shaft of the motor 17 from the winding roller 20. The staff removes the winding roller 20 from the left part of the base 1, and then places the next winding roller 20 on the left part of the base 1, and then pushes the slider 18 backward to engage the output shaft of the motor 17 with the winding roller 20. The staff repeats the above steps to continue coating the OPP protective film.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
