Description

Technical Field

[0001] This utility model relates to the field of film coating equipment technology, and in particular to a continuous film coating equipment. Background Technology

[0002] PET is a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface. It exhibits good creep resistance, fatigue resistance, abrasion resistance, and dimensional stability. It has low wear and high hardness, possessing the greatest toughness among thermoplastics. It also has good electrical insulation properties, is non-toxic, weather-resistant, and has good chemical stability.

[0003] For example, Chinese Patent Publication No. CN221161501U discloses a PET film coating device, including a main body. A bottom film roll is rotatably mounted on one end of the main body. Several conveyor rollers are rotatably mounted inside the top of the main body. The conveyor rollers are connected to the same conveyor belt. Two first support plates are provided on the main body. A coating roll is rotatably mounted on the two first support plates. A first positioning roller and a first dust-adhesive roller are rotatably mounted between the two first support plates. The first positioning roller is located directly above the first dust-adhesive roller. In this invention, the conveyor rollers are driven by a motor to rotate, so that the conveyor belt transports and merges the bottom film and the coating film. The conveyor rollers drive the transmission wheel to rotate. Through the belt connection, the driven wheel drives the reciprocating screw to rotate, so that the reciprocating slider drives the slide bar and scraper to move horizontally along the axial direction of the reciprocating screw, thereby compacting the merged bottom film and coating film again, thereby removing air at the joint. Compared with the prior art, the effect of air bubble removal is improved.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] The above technical solution is not convenient for synchronous lamination of PET mesh, thus reducing the lamination efficiency of PET mesh. Utility Model Content

Inside the film-coating box, two symmetrically arranged PET mesh unwinding rollers and PET release film unwinding rollers are installed in sequence. Adjustable roller pressing mechanisms are installed on the film-coating box at positions corresponding to the PET mesh unwinding rollers and PET release film unwinding rollers.

[0010] In the aforementioned continuous web covering and film covering device, the roller pressing mechanism includes an adjustable lifting seat.

[0011] In the aforementioned continuous netting and film coating device, a roller frame is fixedly connected to the bottom of the lifting seat, and an adjusting pressure roller is rotatably mounted on the roller frame via an installation shaft.

[0012] In the above-mentioned continuous netting and film covering device, a mounting base is fixedly connected to the film covering box, a threaded sleeve is fixedly connected to the center of the mounting base, an adjusting bolt is threadedly connected to the threaded sleeve, and the side of the adjusting bolt near the lifting base is rotatably connected to the lifting base through a bearing.

[0013] In the aforementioned continuous web-coating and film-coating device, two guide rollers are symmetrically arranged on the inner walls of both the inlet and outlet.

[0014] In the aforementioned continuous netting and film covering device, both sides of the bottom of the mounting base are fixedly connected to limit telescopic rods, and the other end of the limit telescopic rods is fixedly connected to the top of the lifting base.

[0015] In the aforementioned continuous netting and film covering device, a rotating handwheel for rotating the adjusting bolt is fixedly connected to the top of the adjusting bolt.

[0016] This utility model has at least the following beneficial effects:

[0017] The continuous mesh and film coating device provided by this utility model can simultaneously bond PET mesh and PET release film to products through synchronously designed PET mesh unwinding roller and PET release film unwinding roller. Moreover, it can coat the mesh and film simultaneously from both top and bottom, thereby greatly improving the product coating efficiency. At the same time, by rotating the handwheel to turn the adjusting bolt, and under the action of the threaded sleeve and the adjusting bolt, the adjusting pressure roller is driven to rise and fall, thereby adjusting the pressing distance on the product. This makes it suitable for coating products of different thicknesses, thus greatly improving the practicality of this utility model. Attached Figure Description

Adjustable roller pressing mechanisms 105 are installed on the coating box 1 at positions corresponding to the PET screen unwinding rollers 103 and PET release film unwinding rollers 104.

[0036] Please refer to Figures 1 to 4 As shown, the roller pressing mechanism 105 includes a liftable and adjustable lifting seat 1051.

[0037] Please refer to Figures 1 to 4 As shown, a roller frame 1052 is fixedly connected to the bottom of the lifting seat 1051, and an adjusting pressure roller 10521 is rotatably mounted on the roller frame 1052 via an installation shaft.

[0038] Please refer to Figures 1 to 4 As shown, a mounting base 1053 is fixedly connected to the film-coating box 1. A threaded sleeve 10531 is fixedly connected to the center of the mounting base 1053. An adjusting bolt 10532 is threadedly connected to the threaded sleeve 10531. The side of the adjusting bolt 10532 closest to the lifting base 1051 is rotatably connected to the lifting base 1051 through a bearing.

[0039] Please refer to Figures 1 to 4 As shown, two guide rollers 1011 are symmetrically arranged on the inner walls of both the feed inlet 101 and the discharge outlet 102;

[0040] By adopting the above technical solution, the guide roller 1011 is set to guide the product to be coated, thereby increasing the stability of product conveying.

[0041] Please refer to Figures 1 to 4 As shown, both sides of the bottom of the mounting base 1053 are fixedly connected to the limiting telescopic rods 1054, and the other end of the limiting telescopic rods 1054 is fixedly connected to the top of the lifting base 1051.

[0042] By adopting the above technical solution, the limiting telescopic rod 1054 is set to limit the lifting seat 1051, thereby increasing the stability of the lifting adjustment of the lifting seat 1051.

[0043] Please refer to Figures 1 to 4 As shown, a rotating handwheel 1055 for rotating the adjusting bolt 10532 is fixedly connected to the top of the adjusting bolt 10532;

[0044] By adopting the above technical solution, the adjustment bolt 10532 can be easily rotated by setting a rotating handwheel 1055, thereby improving the convenience of adjusting the adjustment roller 10521.

[0045] The working principle of this utility model is as follows: not only can the PET mesh unwinding roller 103 and PET release film unwinding roller 104, which are designed synchronously, be used to simultaneously bond the PET mesh and PET release film to the product, but the mesh and film can also be applied simultaneously from top to bottom, thereby greatly improving the product bonding efficiency. At the same time, by rotating the handwheel 1055 to rotate the adjusting bolt 10532, and under the action of the threaded sleeve 10531 and the thread of the adjusting bolt 10532, the adjusting pressure roller 10521 is driven to rise and fall, thereby adjusting the pressing distance on the product. This makes it suitable for products with different thicknesses of film, thus greatly improving the practicality of this utility model.

[0046] The usage process of the continuous web coating and film coating device provided in this embodiment is as follows:

[0047] 1. Preparation stage:

[0048] Ensure that components such as the film coating box 1, PET mesh unwinding roller 103, PET release film unwinding roller 104, and roller pressing mechanism 105 are installed completely and securely.

[0049] Check that the guide rollers 1011 are installed correctly to ensure that they can smoothly guide the product to be coated.

[0050] Based on the thickness of the product to be coated, the height of the adjusting roller 10521 is pre-adjusted by rotating the handwheel 1055 to ensure an appropriate pressing gap.

[0051] 2. Startup and debugging:

[0052] Turn on the power to the laminating device and start the PET mesh unwinding roller 103 and the PET release film unwinding roller 104 to begin unwinding.

[0053] By observing the product's conveying process, the position of the guide roller 1011 is finely adjusted to ensure that the product can smoothly and continuously pass through the feed inlet 101 into the coating box 1.

[0054] Further check the pressing condition of the adjusting roller 10521, and make fine adjustments by rotating the handwheel 1055 if necessary to achieve the best pressing effect.

[0055] 3. Lamination process:

[0056] The product to be coated is fed into the coating box 1 through the feed inlet 101. The product will pass through the PET mesh unwinding roller 103 and the PET release film unwinding roller 104 in sequence.

[0057] Under the action of the roller pressing mechanism 105, the PET mesh and PET release film will be synchronously bonded to the product to form a continuous coating effect.

[0058] After being pressed by the adjusting pressure roller 10521, the product will become flatter and denser, and then be output through the discharge port 102.

[0059] 4. Monitoring and maintenance:

[0060] During the lamination process, the product delivery and lamination quality should be continuously monitored to ensure everything is normal.

[0061] If any problems are found (such as product jamming, uneven coating, etc.), the machine should be stopped immediately for inspection and troubleshooting.

[0062] Regularly clean and maintain the coating equipment to keep it in good working order.

[0063] 5. Conclusion and Closing:

[0064] After completing the lamination of a batch of products, turn off the power to the laminating device and stop the operation of the PET mesh unwinding roller 103 and the PET release film unwinding roller 104.

[0065] Clean the residue inside the coating box 1 to ensure smooth operation next time.

[0066] Return the device to its original position and store it properly for future use.

[0067] The above process enables efficient and stable continuous web coating and film coating of products, improving production efficiency and product quality.
