Description

Technical Field

[0001] This invention belongs to the field of coated paper technology, and specifically relates to a humidification water recycling device for coated paper. Background Technology

[0002] Laminated paper is a composite material made by coating plastic particles onto the surface of paper using a casting machine. Its main characteristics are oil resistance (relatively), water resistance (relatively), and heat-sealing capability. Different uses utilize different properties: when used for packaging hamburgers, its oil resistance is valued. For example, McDonald's uses 80-degree edible vegetable oil that doesn't leak after 10 minutes. When used for packaging coated paper, its water resistance is valued. When used in automatic packaging machines, its heat-sealing capability is valued. Laminated paper can be classified by whether it has a plastic release liner or not; it can also be classified by release agent: silicone release liner and non-silicone release liner. Plastic-coated paper has a release agent with certain penetrating properties. Without a barrier, the release agent can penetrate into the paper, causing poor curing and excessive release agent usage (leading to high costs), among other problems. Therefore, a plastic coating process (commonly known as lamination) is required on the paper. In China, polyethylene (PE) particles are generally used for lamination, requiring a melt flow index of around 7. Domestically produced PE particles are generally Yanshan Petrochemical's 1C 7A. Release papers are divided into single-plastic and double-plastic release papers; non-plastic release papers mainly include glassine, CCK, and other specially treated release papers. Laminated paper requires humidification during processing.

[0003] Existing humidification devices for coated paper generally only humidify the surface of the coated paper. After humidification, the coated paper needs to be properly dried or put into use immediately to avoid prolonged exposure to a humid environment, which can lead to mold growth or bacterial growth. Furthermore, the water used in the humidification process cannot be effectively recycled, which is not environmentally friendly. Therefore, we propose a humidification water recycling device for coated paper to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a humidification water recycling device for coated paper, which can uniformly humidify coated paper and dry it immediately, avoiding the paper from becoming moldy or growing bacteria due to prolonged exposure to a humid environment, and can effectively recycle the water used in the humidification process of coated paper.

[0010] In a preferred embodiment, the spraying mechanism includes a water storage tank, a submersible pump mounted on the bottom wall of the water storage tank, an L-shaped branch pipe fixedly connected to the input end of the submersible pump, and a drain pipe fixedly connected to the output end of the submersible pump. A horizontally arranged first water guide plate is snapped into the water storage tank, and the first water guide plate has a hollow structure. The drain pipe communicates with the interior of the first water guide plate. Multiple guide pipes are fixedly connected to the first water guide plate, and the multiple guide pipes all penetrate the side wall of the water storage tank. The multiple guide pipes are all fixedly connected to a hollow second water guide plate. Multiple spray nozzles are snapped into the second water guide plate, and the multiple spray nozzles communicate with the interior of the second water guide plate.

[0011] In a preferred embodiment, the drying mechanism includes a horizontally arranged second support plate, on which a horizontally arranged movable plate is slidably connected.

[0012] In a preferred embodiment, the moving body includes a vertically arranged moving block, and a third electric rotating rod is engaged with the moving block. Each of the two first support plates is provided with a sliding groove that matches the moving block. A rotating rod is rotatably connected to the moving block, and the rotating rod is threadedly connected to the side wall of the first support plate.

[0017] The feeding roller is opened to feed the coated paper, which is then wound onto the take-up roller after passing through the guide roller. The submersible pump is turned on, and water is pumped into it via an L-shaped branch pipe. The water then enters the first guide plate through the drain pipe. Once the first guide plate is full, the water flows through multiple guide pipes into the second guide plate. When the second guide plate is full, the water simultaneously enters multiple spray nozzles, which spray and humidify the coated paper between the feeding roller and the guide roller. The heater is turned on, and heated air enters the dispersion plate. The hot air is dispersed by the dispersion net and then conveyed to the guide roller. The coated paper between the roller and the receiving roller is dried immediately after humidification to prevent the paper from being left in a humid environment for a long time, which could cause the paper to mold or grow bacteria. The driver is turned on to drive the gear to rotate, which in turn drives the moving block to move horizontally. When the control switch moves to the second stop, the control switch contacts the second stop and triggers the control switch to stop the driver. At this time, the moving plate is reset under the action of the return spring. The timer start is set for the control switch, which can make the moving plate reciprocate on the second support plate to more evenly dry the coated paper.

[0018] During the drying process of the coated paper, the water vapor generated rises and comes into contact with the condenser plate, where it liquefies into water. The water then flows into the recovery tank through the first and second guide channels. Excess water during the coating paper spraying process falls into the recovery tank. The filter screen filters the water entering the recovery tank, facilitating water recovery. The recovered water is then injected into the storage tank for recycling. Attached Figure Description
