Description

Technical Field

[0001] This invention relates to the field of coating technology, and in particular to a coating device and process for a double-layer kitchen dishcloth. Background Technology

[0002] Kitchen cloths, also known as kitchen paper towels, are special paper towels for the kitchen. They are larger and thicker than regular paper towels, with better absorbency, making them a great helper for wiping away oil and grease from food. Kitchen paper towels can be purchased in large supermarkets. Using kitchen paper towels instead of dishcloths makes cleaning the kitchen easier and more effective. Even after washing them daily, dishcloths accumulate a large number of bacteria after several days of use. Continuing to use them not only makes the kitchen dirtier, but also leaves a large number of invisible bacteria on your hands and the surfaces you've wiped, posing a threat to your family's health. Kitchen paper towels, on the other hand, have strong cleaning power and are disposable, making them a clean and hygienic alternative to dishcloths, protecting your family from bacterial infections.

[0003] In the existing technology, the production process of kitchen cloths requires lamination, which involves processing multiple layers of material and pressing them together into a whole. During the lamination process, heating is required to facilitate pressing. In the existing technology, the lamination device usually uses a fan to directly cool the pressed film, which has a poor cooling effect. Cooling by blowing air through a fan can easily cause air bubbles to form between the film and the paper, affecting product quality and making it unsellable. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating device and process for a double-layer kitchen dishcloth.

[0014] As a further embodiment of the present invention: the outer wall of the bottom of the support leg is provided with an anti-slip pad, the anti-slip pad is made of rubber material, and the bottom of the anti-slip pad is provided with annular texture.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. In use, the first drive motor is bolted to the material roller. Starting the first drive motor rotates the material roller, winding the main body of the wiping cloth onto it. The film roll roller then winds the film layer to complete the feeding. Switching the forward and reverse directions of the first drive motor controls the winding and conveying of the wiping cloth. The rotating film roll roller conveys the collected film layer for pressing. Before pressing, the film layer and the wiping cloth are conveyed through the gap between two sets of limit rollers. The limit rollers have smooth surfaces, allowing the film layer and the wiping cloth to slide through them. The small gap between the limit rollers ensures the film layer and the wiping cloth are properly aligned. The film layer and the main body of the dishcloth, which are attached together and attracted to each other by the limiting rollers, enter the space of the mounting frame. The telescopic motor is started, which drives the telescopic rod to fall, causing the pressing roller to contact the film layer and the main body of the dishcloth. The third drive motor is started, which drives the drive shaft to rotate. The rotation of the drive shaft drives the pressing roller fixed to the drive shaft to rotate, pressing the film layer and the main body of the dishcloth to complete the lamination and form a kitchen dishcloth. At the same time as the lamination is completed, the rotation of the pressing roller drives the kitchen dishcloth forward. The pressing roller performs full pressing, so that the film layer and the main body of the dishcloth are seamlessly combined, which can effectively prevent the formation of air bubbles.

[0017] 2. To facilitate assembly and prevent delamination, adhesive is supplied to the storage compartment via a delivery pipe. Bolts are installed at the connection points using connecting flanges to reinforce the connection and prevent breakage. The volume of adhesive in the storage compartment can be observed through a transparent viewing window. The delivery pump is activated to feed the adhesive from the storage compartment into the nozzle, which sprays it onto the film layer and the main surface of the cloth. A scraper on one side of the nozzle evenly spreads the adhesive during delivery. The adhesive prevents delamination and reinforces the film coating.

[0018] 3. The heating element is activated to heat the internal space of the mounting bracket. The increased temperature allows the adhesive to fuse more thoroughly with the kitchen cloth when it is applied by the scraper. At the same time, the heating rollers are heated to ensure a more thorough bonding of the film during the pressing process.

[0019] 4. One end of the feed pipe is threaded, and the pipe is connected to the feed pipe through the thread to transport water into the chiller. The chiller is turned on and off by the buttons on the control panel. After the temperature is adjusted, the water is cooled and sent into the chamber through the feed pipe. The coated kitchen cloth is rolled up through the opening of the chamber. The chamber temperature is lowered by cold water, and the kitchen cloth is cooled by contact with the opening of the chamber.

One end of the drive shaft 28 can rotatably pass through the second connecting frame 29. A pressing roller 30 is fixed to the outer wall of the drive shaft 28 by a set screw.

[0034] In use, the first drive motor 4 is bolted to the material roller 5. Starting the first drive motor 4 rotates the material roller 5, winding the main body of the wiping cloth onto it. The film layer is then wound up by the film roll roller 3 to complete the feeding process. Switching the forward and reverse directions of the first drive motor 4 controls the winding and conveying of the wiping cloth. The film roll roller 3 conveys the collected film layer for pressing. Before pressing, the film layer and the wiping cloth are conveyed through the gap between two sets of limiting rollers 11. The limiting rollers 11 have smooth surfaces, allowing the film layer and the wiping cloth to slide through them. The small gap between the limiting rollers 11 allows the film layer and the wiping cloth to adhere together. The film layer and the main body of the rag, which are attracted to each other by the limiting roller 11, enter the space of the mounting frame 24. The telescopic motor 25 is started, which drives the telescopic rod 36 to fall down, which drives the pressing roller 30 to contact the film layer and the main body of the rag. The third drive motor 33 is started, which drives the drive shaft 28 to rotate. The rotation of the drive shaft 28 drives the pressing roller 30 fixed to the drive shaft 28 to rotate, pressing the film layer and the main body of the rag to complete the film coating and form a kitchen rag. At the same time as the film coating is completed, the rotation of the pressing roller 30 drives the kitchen rag forward. The pressing roller 30 performs full pressing, so that the film layer and the main body of the rag are seamlessly combined, which can effectively prevent the formation of air bubbles.

[0035] The spraying assembly includes a spray nozzle 32, which is fixedly mounted to the inner wall of the mounting frame 24 by bolts.
