Description

Technical Field

[0001] The utility model belongs to the technical field of plastic film humidifying devices, in particular to a plastic film humidifying device. Background Art

[0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging and as coatings. Plastic packaging and plastic packaging products are occupying an increasingly larger share of the market, especially composite plastic flexible packaging, which has been widely used in the fields of food, medicine, and chemical industry. Among them, food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives. In order to prevent static electricity from generating during the production process of plastic film, humidification is generally carried out during the production of plastic film.

[0003] For example, a plastic film humidifying device, as disclosed in publication number CN219686621 U, comprises a mounting frame, an air pipeline, a valve, an air hose, a mounting frame, a steam box, an exhaust fan, and a rotary drive device. Steam can be released from the air pipeline through the valve, and the released steam enters the connecting pipe through the air hose. The steam is discharged into the steam box through the exhaust fan, and then discharged onto the surface of the plastic film through the vent holes on the steam box, thereby achieving a humidifying effect on the plastic film. The steam discharged by the exhaust fan hits the side of the steam box where the vent holes are provided, with a portion of the steam being discharged directly through the vent holes, and a portion being blocked by the inner wall of the steam box and then dissipated to the vent holes in other areas for discharge, thereby expanding the steam coverage area on the surface of the plastic film.

[0004] This humidification device uses a fan and a steam box to blow steam into the air, which is then affected by gravity and drips onto the plastic film. This humidification method causes a large amount of water mist to float in the air, and less water mist is actually used for humidification, resulting in serious waste of water mist. In order to solve the above problem, a plastic film humidification device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic film humidifying device to solve the above problems, comprising:

[0006] A water tank, wherein a humidifying roller is rotatably connected to the interior of the water tank;

[0007] A fixed rod is fixedly installed on one side of the water tank. One side of the fixed rod is slidably connected to a movable plate, and a plurality of rollers are fixedly installed on the lower surface of the movable plate.

[0008] Through the technical scheme, in the plastic film processing process, the plastic film is placed between the humidifying roller and the moving plate, the moving plate is pulled to make the rollers at the bottom of the moving plate press on the upper surface of the plastic film, when the plastic film is pulled, the humidifying roller is rotated, the humidifying roller is in contact with water in the water tank in the rotating process, water is attached to the outer wall of the humidifying roller and contacts the outer wall of the plastic film, so that the outer wall of the plastic film is humidified, and the humidifying device does not make water evaporate in the air, so that the waste of water resources is greatly reduced.

[0009] In a preferred embodiment, the upper end of the fixed rod is rotatably connected with a lead screw, and the lead screw is threadedly connected with one end of the moving plate on the inside of the fixed rod.

[0010] Through the technical scheme, the moving plate is moved up and down along one side of the fixed plate by rotating the lead screw.

[0011] In a preferred embodiment, support columns are welded to the bottom of the water tank on both sides, and a plurality of threaded holes are formed in the outer wall of the support columns.

[0012] Through the technical scheme, the humidifying device can be fixedly installed on various plastic film processing equipment through the support columns.

[0013] In a preferred embodiment, a water pump is fixedly installed on one side of the water tank, the input end of the water pump is connected with municipal water supply through a water pipe, and the output end of the water pump is fixedly connected with one side of the water tank through a water pipe.

[0014] Through the technical scheme, when the liquid level in the water tank decreases, the water pump supplies water to the inside of the water tank.

[0015] In a preferred embodiment, water-absorbing cotton is fixedly installed on the inner wall of the water tank on both sides of the upper end.

[0016] Through the technical scheme, when the humidifying roller contacts water, large water droplets are retained on the outer wall of the humidifying roller, and the water-absorbing cotton can absorb the large water droplets, so that the water added to the plastic film is not too much.

[0017] In a preferred embodiment, a hand wheel is arranged at the upper end of the lead screw.

[0018] Through the technical scheme, the hand wheel is arranged to facilitate the rotation of the lead screw.

[0019] As described above, due to the adoption of the technical scheme, the beneficial effects of the plastic film humidifying device are: the plastic film humidifying device is provided.

[0020] During the plastic film processing process, the plastic film is placed between the humidifying roller and the movable plate. The movable plate is pulled to press the roller at the bottom of the movable plate onto the upper surface of the plastic film. When the plastic film is pulled, it drives the humidifying roller to rotate. During the rotation, the humidifying roller continuously contacts the water in the water tank. The water is contaminated on the outer wall of the humidifying roller and contacts the outer wall of the plastic film, thereby humidifying the outer wall of the plastic film. This humidifying equipment will not cause moisture to float in the air, greatly reducing the waste of water resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example:

[0028] A plastic film humidifying device, comprising:

[0029] The water tank 1 has a humidifying roller 2 rotatably connected therein. Support columns 6 are welded on both sides of the bottom of the water tank 1. The outer wall of the support columns 6 is provided with multiple threaded holes. The humidifying device can be fixedly mounted on various plastic film processing equipment through the support columns 6.

[0030] When the water tank 1 is emptied, the water tank 1 is moved upwards and downwards, and the water tank 1 is moved downwards and downwards, so that the water tank 1 is moved upwards and downwards, thereby the water tank 1 is moved downwards and downwards, thereby the water tank 1 is moved downwards and downwards, thereby the water tank 1 is moved downwards and downwards, thereby the water tank 1 is moved downwards and downwards, thereby the water tank 1 is moved downwards and downwards,

[0031] A water pump 9 is fixedly installed on one side of the water tank 1. The input end of the water pump 9 is connected to the municipal water supply through a water pipe, and the output end of the water pump 9 is fixedly connected to one side of the water tank 1 through a water pipe. When the liquid level in the water tank 1 drops, water is supplied to the inside of the water tank 1 through the water pump 9. Absorbent cotton 8 is fixedly installed on both sides of the upper end of the inner wall of the water tank 1. When the humidifying roller 2 comes into contact with water, large water droplets will remain on its outer wall. The large water droplets can be absorbed by the absorbent cotton 8, thereby preventing excessive moisture from increasing on the plastic film.

[0032] Working principle:

[0033] During the processing of plastic film, the plastic film is placed between the humidifying roller 2 and the movable plate 4. The movable plate 4 is pulled so that the roller 5 at the bottom of the movable plate 4 is pressed against the upper surface of the plastic film. When the plastic film is pulled, it drives the humidifying roller 2 to rotate. During the rotation, the humidifying roller 2 continuously contacts the water in the water tank 1. The water is contaminated on the outer wall of the humidifying roller 2 and contacts the outer wall of the plastic film, thereby humidifying the outer wall of the plastic film. This humidifying equipment will not cause moisture to float in the air, greatly reducing the waste of water resources.
