Description

Technical Field

[0001] This utility model relates to the field of tape production technology, and in particular to a coating machine for Mylar tape production. Background Technology

[0002] A tape coating machine applies specific functional adhesives, coatings, or inks to a tape substrate. Tape substrates typically include plastic film, paper, cloth, leather, etc. After coating, the tape substrate is dried, wound up, and packaged.

[0003] A Chinese patent, CN219334743U, describes a tape coating machine. By having one end of a scraper contact the periphery of the coating roller, the scraper removes adhesive adhering to the roller surface as the roller rotates with the substrate. The scraper, baffle, and two side plates form a cavity to collect the scraped-off adhesive, ensuring complete adhesion between the coating roller periphery and the substrate surface, resulting in uniform adhesive distribution. The upper end of the scraper is angled to direct the waste adhesive towards the discharge pipe, facilitating discharge and reducing the probability of waste adhesive accumulation on the scraper. However, some fabrics may accumulate impurities, such as dust, during transport. If dust is widespread, even if the fabric appears adhered initially, bending, stretching, or temperature changes during use can easily cause delamination and separation, requiring cleaning before coating. Therefore, a Mylar tape coating machine is proposed to address these issues. Utility Model Content

[0004] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a coating machine for Mylar tape production, which solves the problem of dust and other impurities adhering to the side of the fabric to be coated before the adhesive is applied by setting up a collection pipe and a scraper.

[0005] (II) Technical Solution This utility model provides a coating machine for Mylar tape production, including a housing, multiple guide rollers and a spraying machine. A support frame is provided inside the housing, and a fan is provided at the top of the support frame. The multiple guide rollers are rotatably disposed inside the housing and are respectively located on the front and rear sides of the support frame. The fabric is disposed on the multiple guide rollers and passes through the support frame. The spraying machine is disposed on the top wall of the inner cavity of the housing, and also includes; An adsorption panel is connected to the front side of the support frame by two support rods, and the fabric is attached to the adsorption area of ​​the adsorption panel. The collection tubes are spaced apart above the adsorption panel, and a scraper is connected to the outside of the collection tubes. The scraping end of the scraper is pressed against the surface of the fabric.

[0010] Preferably, a pressure roller is provided on the front side of the support frame, and a glue scraper is provided on the front side of the pressure roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up an adsorption panel, the fabric is made to fit more closely to the adsorption area of ​​the panel when the guide roller transports the fabric, improving the coating effect of the coating roller and the glue spraying machine. Before spraying glue, impurities on the fabric are scraped off using a collection pipe and a scraper on the collection pipe, and then collected through the collection pipe.

[0016] like Figure 1-4 As shown, the present invention proposes a coating machine for Mylar tape production, including a housing 1, multiple guide rollers 2 and a sprayer 3. A support frame 11 is provided inside the housing 1, and a fan 12 is provided at the top of the support frame 11. The multiple guide rollers 2 are rotatably disposed inside the housing 1 and are respectively located on the front and rear sides of the support frame 11. The fabric is disposed on the multiple guide rollers 2 and passes through the support frame 11. The sprayer 3 is disposed on the top wall of the inner cavity of the housing 1, and also includes; Adsorption panel 4 is connected to the front side of support frame 11 by two support rods, and the fabric is attached to the adsorption area of ​​adsorption panel 4. Collection tubes 5 are spaced above the adsorption panel 4. A scraper 51 is connected to the outside of the collection tubes 5. The scraping end of the scraper 5 is pressed against the surface of the fabric.

[0017] In this invention, the spraying machine 3 sprays the fabric, and the fan 12 above the support frame 11 blows air onto the sprayed fabric. Multiple guide rollers 2 are used to transport the fabric. The support frame 11 is hollow inside and has a through groove to allow the fabric to pass through. The fabric is transported using multiple guide rollers 2, and adhesive is sprayed and rolled onto it. Thin, soft, slippery, or highly elastic fabrics are still very prone to fine wrinkles, shaking, or localized stretching under the action of transport and tension. Once the fabric enters the adhesive spraying area with wrinkles, the adhesive will be sprayed onto the uneven surface. However, when the adsorption panel 4 is used below the fabric, the vacuum adsorption force tightly and smoothly "pulls" and "sticks" the fabric to the panel, flattening all areas of the fabric like ironing. This provides an absolutely flat and stable working reference surface for spraying / rolling glue, eliminating quality problems caused by fabric wrinkling at the source. Then, before spraying glue, the glue-coated side of the fabric is cleaned using the collection pipe 5 and scraper 51 to prevent dust from getting on the fabric during the conveying process, which would affect the subsequent coating effect.

[0018] In an optional embodiment, a vacuum generator 41 is provided at the bottom of the adsorption panel 4 and is connected to the adsorption panel 4 through multiple connecting pipes.

[0019] It should be noted that a control valve is also provided between the vacuum generator 41 and the adsorption panel 4 to adjust the suction force.

[0020] In an optional embodiment, one end of the collection pipe 5 is connected to a fixed pipe 52, a vacuum cleaner 54 is provided on the outside of the housing 1, a flexible hose 55 is connected between the vacuum cleaner 54 and the fixed pipe 52, a collection groove is provided on the collection pipe 5, and a grid 53 is provided on the collection groove.

[0021] It should be noted that by using a vacuum cleaner 54, which is a relatively mature and widely used technology, a power source and a collection container are provided for vacuuming. When the scraper 51 scrapes off the dust and impurities, the suction force generated by the vacuum cleaner 54 sucks the impurities through the mesh 53 into the collection tube 5, through the fixed tube 52 into the hose 55, and then into the vacuum cleaner 54. Because the mesh 53 is set, the cloth will not be sucked up when vacuuming. A window that matches the size of the fixed tube 52 is opened on one side of the housing 1.

[0022] In an optional embodiment, two limiting frames 6 are arranged opposite each other at the top of the adsorption panel 4. A fixing rod 61 is connected between the upper and lower walls of the limiting frame 6. A slider 62 is slidably arranged on the outer side of the fixing rod 61 and is slidably connected to the inner wall of the limiting frame 6. A spring 63 is sleeved on the outer side of the fixing rod 61, and its two ends are respectively connected to the top wall of the limiting frame 6 and the top of the slider 62.

[0023] It should be noted that by setting spring 63 to provide downward tension to the two sliders 62, the scraper 51 can always be closer to the fabric, resulting in a better scraping effect.

[0024] In an optional embodiment, one end of the collecting tube 5 is fixedly connected to a slider 62 on one side, the fixed tube 52 passes through the slider 62 on the other side and extends to the outside of the housing 1.

[0025] In an optional embodiment, a pressure roller 13 is provided on the front side of the support frame 11, and a scraper hopper 14 is provided on the front side of the pressure roller.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
