Description

Technical Field

[0001] This utility model relates to the technical field of PE film dyeing mechanism, and more specifically to an environmentally friendly PE film dyeing mechanism. Background Technology

[0002] PE film is a thin film made of polyethylene plastic. In food packaging, it can be used to package food, effectively protecting its taste and nutritional components. In pharmaceutical packaging, it can be used for outer packaging of medicines, syringe tips, infusion bags, etc., ensuring the quality and safety of medicines. Furthermore, it is widely used in the packaging of daily necessities, such as household cleaners, personal hygiene products, and pet supplies. Coloring PE film can make products more eye-catching on shelves, attracting consumers' attention. For example, using colored PE film for food packaging can convey the product's flavor or characteristics through vibrant colors, stimulating consumers' desire to buy.

[0003] For example, a dyeing device with a transverse stirring mechanism is disclosed in the prior art (CN218251163U). This utility model can transport the more concentrated solution at both ends of the dyeing tank to the middle by setting the transverse stirring mechanism, thereby improving the uniformity of the dyeing solution and ensuring uniform dyeing of the film material.

[0004] However, the existing technology described above still has the following problems when used: When dyeing PE film materials using an immersion method, dust on the surface of the PE film mixes with the solution, and the solution needs to be frequently replaced after becoming contaminated, resulting in waste. Furthermore, the solution distribution on the film surface is uneven, with some solutions being too much and others too little, leading to low dyeing results. Based on this, this utility model provides an environmentally friendly PE film dyeing mechanism with high dyeing efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides an environmentally friendly PE film dyeing mechanism. It uses a soft brush roller and a dust suction pipe to clean the dust from the upper and lower surfaces of the PE film, preventing dust from affecting the subsequent dyeing effect. A spray gun is used to spray UV dye onto the upper and lower surfaces of the PE film, and ultraviolet light is used for curing. This method offers fast dyeing speed, high efficiency, and does not produce volatile organic compounds during the curing process, making it highly environmentally friendly and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly PE film dyeing mechanism, comprising a base, a cleaning box and a dyeing box fixedly mounted on the top of the base, two soft-bristled brush rollers symmetrically distributed inside the cleaning box for cleaning the surface of the PE film, dust removal pipes fixedly passing through the top and bottom of the cleaning box, multiple spray guns and multiple ultraviolet lamps inside the dyeing box, the multiple spray guns and multiple ultraviolet lamps respectively positioned above and below the PE film, the multiple spray guns being connected to an infusion assembly, and material inlets opened on both sides of the cleaning box and both sides of the dyeing box.

[0007] In a preferred embodiment, an industrial vacuum cleaner is provided at the rear of the base. The industrial vacuum cleaner is connected to two dust removal pipes. The industrial vacuum cleaner can be used to remove dust from the upper and lower surfaces of the PE film, reducing the impact of dust on the subsequent dyeing effect.

[0008] In a preferred embodiment, the infusion assembly includes a storage tank located behind the dyeing box and on one side of the industrial vacuum cleaner. The storage tank contains UV dye, and an infusion pump is fixedly installed on the top of the storage tank. The infusion pump is connected to multiple spray guns through a delivery pipe, and the UV dye is automatically delivered by the infusion pump, thereby improving the dyeing efficiency of the PE film material.

[0009] In a preferred embodiment, the inner cavity of the cleaning box is provided with two first conveying rollers on the side away from the soft brush roller, and the inner cavity of the dyeing box is provided with two second conveying rollers on both sides. The two first conveying rollers and the two second conveying rollers are distributed on the top and bottom of the PE film material. The PE film material is conveyed by the cooperation of the first conveying rollers and the second conveying rollers, thereby realizing the continuous dyeing of the PE film material.

[0010] In a preferred embodiment, the cleaning box is detachably connected to the front and rear sides with first door panels. Two soft brush rollers and two first conveying rollers are rotatably disposed between the two first door panels. Removing the first door panels facilitates the disassembly and maintenance of the soft brush rollers and the first conveying rollers.

[0011] In a preferred embodiment, the dyeing box is detachably connected to a second door panel on both the front and rear sides, and multiple ultraviolet lamps and multiple second conveyor rollers are rotatably arranged between the two second door panels, which facilitates the disassembly of ultraviolet lamps and second conveyor rollers by staff for inspection and replacement.

[0012] In a preferred embodiment, two third conveying rollers are fixedly provided on both the side of the cleaning box away from the dyeing box and the side of the dyeing box away from the cleaning box. The two third conveying rollers are distributed on the top and bottom of the PE film material. The use of the third conveying rollers can further improve the stability of the PE film material during the conveying process.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention uses two soft brush rollers inside the cleaning box in conjunction with an industrial vacuum cleaner to remove dust from the upper and lower surfaces of the PE film, preventing dust from affecting the subsequent dyeing effect of the PE film. Then, multiple spray guns simultaneously spray UV dye onto the upper and lower surfaces of the PE film, and use ultraviolet lamps to irradiate the surface of the PE film for curing and dyeing. The dyeing speed is fast and the effect is high. No volatile organic compounds are generated during the curing process, making it highly environmentally friendly. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figures 1-5This utility model provides an environmentally friendly PE film dyeing mechanism, including a base 1. A cleaning box 2 and a dyeing box 3 are fixedly installed on the top of the base 1. The cleaning box 2 and the dyeing box 3 are provided with material inlets 9 on both sides for conveying PE film. The cleaning box 2 is provided with two soft bristle brush rollers 4 symmetrically distributed inside for cleaning the surface of the PE film. Dust removal pipes 5 are fixedly installed through the top and bottom of the cleaning box 2. An industrial vacuum cleaner 10 is provided behind the base 1 and is connected to the two dust removal pipes 5.

[0023] The dyeing chamber 3 is equipped with multiple spray guns 6 and multiple ultraviolet lamps 7, which are respectively located above and below the PE film. Each spray gun 6 is connected to a liquid delivery assembly 8. Specifically, the liquid delivery assembly 8 includes a storage tank 81 located behind the dyeing chamber 3 and on one side of the industrial vacuum cleaner 10. The storage tank 81 stores UV dye, and a liquid delivery pump 82 is fixedly installed on the top of the storage tank 81. The liquid delivery pump 82 is connected to the multiple spray guns 6 through a delivery pipe, and the liquid delivery pump 82 automatically delivers UV dye, thereby improving the dyeing efficiency of the PE film.

[0024] In actual use, one end of the PE film is first conveyed into the cleaning box 2. The two soft brush rollers 4 inside the cleaning box 2 can gently brush up the dust on the upper and lower surfaces of the PE film. At the same time, the industrial vacuum cleaner 10 can suck up the dust through the suction pipe to avoid the dust affecting the subsequent dyeing effect of the PE film. In addition, a hose can be used to connect the inside of the dyeing box 3 to the industrial vacuum cleaner 10 to suck up the gas in the dyeing box 3, which can remove odors to a certain extent and reduce the pollution of odors to the environment.

[0025] After cleaning, the PE membrane is transported to the dyeing tank 3. The infusion pump 82 draws the UV dye from the storage tank 81 and delivers it to multiple spray guns 6. The multiple spray guns 6, fixed at the top and bottom of the dyeing tank 3, simultaneously spray out the UV dye, uniformly coating the upper and lower surfaces of the PE membrane. Then, the PE membrane continues to move to the right side of the dyeing tank 3, where multiple ultraviolet lamps 7 irradiate the surface of the PE membrane, causing the photoinitiator in the surface coating to generate free radicals, triggering a chemical reaction between the dye and the PE membrane surface, thus achieving dyeing. This method has a fast dyeing speed and high efficiency. The cured dyed PE membrane has good wear resistance and weather resistance, and the UV dye produces almost no volatile organic compounds such as VOCs during the curing process, making it highly environmentally friendly.

[0026] Refer to the instruction manual appendix Figures 1-5The cleaning box 2 has two first conveying rollers 11 on the side away from the soft brush roller 4 in its inner cavity. The dyeing box 3 has two second conveying rollers 12 on both sides of its inner cavity. The two first conveying rollers 11 and the two second conveying rollers 12 are distributed on the top and bottom of the PE film. The cleaning box 2 and the dyeing box 3 are both fixedly provided with two third conveying rollers 15 on the side away from the dyeing box 3 and the dyeing box 3 and the cleaning box 2, respectively. The two third conveying rollers 15 are distributed on the top and bottom of the PE film.

[0027] By setting up several first conveying rollers 11, second conveying rollers 12 and third conveying rollers 15 to transport PE film, the flatness of PE film during transportation can be maintained to a certain extent.

[0028] Furthermore, the front and rear sides of the cleaning box 2 are detachably connected to the first door panel 13 by bolts, and the two soft brush rollers 4 and the two first conveying rollers 11 are rotatably mounted between the two first door panels 13 by bolts. The front and rear sides of the dyeing box 3 are detachably connected to the second door panel 14 by bolts, and the multiple ultraviolet lamps 7 and the multiple second conveying rollers 12 are rotatably mounted between the two second door panels 14 by bolts.

[0029] The first door panel 13 and the second door panel 14 are detachable, which makes it easy for workers to disassemble the first door panel 13 and the second door panel 14 to inspect and maintain the soft brush roller 4, the first conveying roller 11, the second conveying roller 12 and the ultraviolet lamp 7.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
