Description

Technical Field

[0001] The present application relates to the technical field of coating machines, and in particular to a coating machine for producing composite films. Background Art

[0002] Composite membranes are made by combining two different thin films. During composite membrane production, a coating machine is required to apply a coating to the composite membrane surface, or to combine multiple film layers. Coating machines are widely used in the composite processing of various membrane products.

[0003] The patent with announcement number CN218838684U discloses "a coating machine coating and compounding device, including a bottom plate, and a heating box is arranged on one side of the upper end of the bottom plate. In the utility model, by arranging a heating box outside the extrusion roller and the No. 1 guide roller, the No. 1 unwinding roller and the No. 2 unwinding roller can respectively release the film cloth for compounding, and the heating box can be used to heat it. By extending the heating time, the temperature around the extrusion roller is increased, so that the processed composite film will not immediately come into contact with the lower temperature outdoor air, delaying the cooling efficiency of the composite film, so that the composite plate will not have wrinkles, separation between film layers, etc. due to uneven shrinkage caused by excessive cooling, and the distance between the extrusion roller and the No. 1 guide roller can be adjusted by controlling the pneumatic cylinder, making it more convenient to use."

[0004] Regarding the above-mentioned related technologies, the inventor believes that when the scraper scrapes the paint on the first film layer, it will scrape off the excess paint on the first film layer, and the scraped paint will fall onto the No. 2 unwinding roller or the bottom plate, thereby contaminating the No. 2 unwinding roller or the bottom plate, and increasing the consumption and waste of paint.

[0023] The following is combined with Figures 1-4 This application is described in further detail.

[0024] The embodiment of the present application discloses a coating machine for producing composite films.

[0025] A coating machine for producing composite films, referring to Figure 1-2 , including a body 1, a coating mechanism and a heating box 4.

[0026] Reference Figure 1-2 At both ends of the machine body 1, there are respectively provided with a unwinding roller for unwinding the film and a winding roller for winding the coated film. The unwinding roller and the winding roller are common components of existing coating machines and other equipment. Their internal structures and principles have been disclosed and will not be elaborated here.

[0027] Reference Figure 2-3 The coating mechanism includes a paint outer box 2 fixedly arranged in the machine body 1, a coating roller 21 rotatably arranged in the top of the paint outer box 2 for coating the top film body, and a pressing roller 22 rotatably arranged in the machine body 1 and located directly above the coating roller 21. The coating roller 21 can apply the paint in the paint outer box 2 to its own outer surface. After the coating roller 21 rotates, it can apply the paint on the outer surface to the film body between the pressing roller 22 and the coating roller 21, thereby coating the film body. The coating roller 21 is driven by a motor. This is a public technology and will not be described in detail here.

[0028] Reference Figure 2-3 A scraper 3 is provided on one side of the paint outer box 2 for scraping off excess paint on the coating roller 21 and smoothing the paint. The scraper 3 is inclined, and an adjustment mechanism is provided on the top of the paint outer box 2 for controlling the distance between the scraper 3 and the coating roller 21. An arc-shaped guide plate 35 is provided at the bottom of the adjustment mechanism for guiding the excess paint scraped off by the scraper 3 to the paint outer box 2. The scraped paint will drip into the paint outer box 2 under the guidance of the arc-shaped guide plate 35 and can be reused, thereby reducing the consumption and waste of paint.

[0029] Reference Figure 2-4 The adjustment mechanism includes a carrier 31 fixed to one side of the top of the paint outer box 2, a threaded rod 32 threaded in the top of the carrier 31, and a rotating block 33 fixed at the bottom end of the threaded rod 32. The rotating block 33 is rotatably connected to the top of the scraper 3. The rotating block 33 can connect the threaded rod 32 and the scraper 3 so that the scraper 3 will not fall off from the bottom end of the threaded rod 32.

[0030] Reference Figure 2-4 The scraper 3 is fitted into the inner side of the carrier 31, and the arc-shaped guide plate 35 is fixed to the bottom end of the carrier 31. The arc-shaped guide plate 35 fits against the bottom of the scraper 3, and a gripping rod 34 is fixed to the top of the threaded rod 32 for holding. The arc-shaped guide plate 35 can receive the paint scraped from the scraper 3, and the carrier 31 can support and limit the scraper 3 so that the scraper 3 can slide on the carrier 31 but cannot rotate. The user can drive the threaded rod 32 to rotate by holding the gripping rod 34. At this time, the connection of the rotating block 33 and the limitation of the carrier 31 will drive the scraper 3 to move, thereby controlling the distance between the scraper 3 and the coating roller 21, so that the coating roller 21 can apply different thicknesses to the composite film to apply a coating on the surface of the composite film.

[0031] Reference Figure 2-3 The paint outer box 2 is provided with a pushing mechanism for pushing the paint at the bottom of the paint outer box 2 as the consumption decreases toward the coating roller 21. The pushing mechanism includes a paint inner box 23 that is slidably arranged in the corresponding paint outer box 2 and directly below the coating roller 21, and a plurality of springs 24 that are fixed between the bottom of the paint inner box 23 and the bottom of the inner wall of the paint outer box 2. A seal can be set between the paint inner box 23 and the paint outer box 2. The paint is located between the paint inner box 23 and the top of the paint outer box 2. The paint between the paint inner box 23 and the paint outer box 2 can press the paint inner box 23 downward by its own weight. When the paint becomes lighter as the consumption decreases, the paint inner box 23 will slowly rise under the elastic force of the spring 24 and push the paint toward the coating roller 21, thereby continuously feeding the coating roller 21.

[0032] Reference Figure 2-3 An arc-shaped groove for collecting paint is provided at the bottom of the inner wall of the paint inner box 23, and a through hole is provided on one side of the bottom of the paint outer box 2. The arc-shaped groove helps to collect the paint in the paint inner box 23, so that the collected paint can be pushed to the coating roller 21 by the paint inner box 23 to feed the coating roller 21. The through hole can connect the air in the paint outer box 2 with the outside air, thereby preventing the outside air from failing to enter the bottom of the paint outer box 2 in time when the paint inner box 23 is lifted, thereby hindering the continued movement of the paint inner box 23.

[0033] Reference Figure 1-2 The heating box 4 is fixed in the machine body 1, and a feed roller 5 for conveying another film body is rotatably provided in the machine body 1. A guide roller 41 and an extrusion roller 42 for compounding the two film bodies are rotatably provided in the heating box 4. The extrusion roller 42 is located directly above the guide roller 41. The other film body conveyed by the feed roller 5 and the coated film body can be extruded by the guide roller 41 and the extrusion roller 42, and combined with the heating of the heating box 4 to perform hot pressing compounding to form a composite film. The heating box 4 is provided with heating equipment such as a hot air blower or an electric heating tube.

[0034] Reference Figure 1-2 The body 1 and the heating box 4 are respectively provided with a telescopic part 6 for driving the pressing roller 22 and the squeezing roller 42 to rise and fall. The telescopic part 6 is a driving component with a telescopic effect such as an electric push rod, a cylinder and a hydraulic cylinder. A U-shaped frame is fixed at the bottom end of the telescopic part 6. The pressing roller 22 and the squeezing roller 42 are respectively rotatably connected in the U-shaped frame. The telescopic part 6 can drive the pressing roller 22 and the squeezing roller 42 to rise and fall, so that the pressing roller 22 and the squeezing roller 42 can extrude and guide the film bodies of different thicknesses.

[0035] The implementation principle of a coating coating machine for producing a composite film in the embodiment of the present application is as follows:

[0036] When it is necessary to apply a coating to the surface of the composite film body, one end of the composite film on the unwinding roller of the machine body 1 can be sequentially passed through the coating mechanism, the guide roller 41 and the squeezing roller 42 in the heating box 4 and connected to the winding roller. The coating roller 21 can apply the coating in the coating outer box 2 to its own outer surface. After the coating roller 21 rotates, the coating on the outer surface can be applied to the film body between the nip roller 22 and the coating roller 21, thereby coating the film body and applying the coating;

[0037] At the same time, the scraper 3 can scrape off the excess paint on the coating roller 21 before coating and smooth the paint, so that the coating roller 21 can coat the composite film more evenly. The scraped paint will drip into the coating outer box 2 under the guidance of the arc-shaped guide plate 35 and can be reused, reducing the consumption and waste of paint. The heating box 4 can heat and dry the coated composite film. The guide roller 41 and the squeezing roller 42 can guide the composite film after intermediate coating and drying. The winding roller can wind up the coated composite film.

[0038] When it is necessary to composite the film body released by the unwinding roller and the other film body sent by the feed roller 5, the other film body can also pass through the guide roller 41 and the squeezing roller 42 in the heating box 4 and be connected to the winding roller. At this time, the coating mechanism will still coat the film body released by the unwinding roller. The other film body transported by the feed roller 5 and the coated film body can be squeezed by the guide roller 41 and the squeezing roller 42, and combined with the heating of the heating box 4 to perform hot pressing composite to form a composite film, so as to produce the composite film.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
