Description

Technical Field

[0001] This utility model relates to the field of thin film coating technology, specifically to an online coating device for high-barrier thin films. Background Technology

[0002] High-barrier films are produced by extruding a material with strong gas barrier properties and a polyolefin with strong heat-sealing and moisture barrier properties simultaneously. They are multi-layered films.

[0003] However, most existing high-barrier film coating devices do not have the function of slitting and trimming high-barrier films, which leads to manual lamination after the subsequent lamination is completed. This adds an extra step, which not only reduces production efficiency but may also affect the quality of the film. Existing high-barrier film coating devices that do have slitting and trimming functions generally do not recycle the high-barrier film raw materials, which wastes a lot of high-barrier film raw materials. Utility Model Content

[0004] The purpose of this invention is to provide an online coating device for high-barrier films to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online coating device for high-barrier films, comprising a frame, a feeding mechanism, a cutting mechanism, a coating mechanism, and a discharging mechanism. The feeding mechanism is located at one end of the frame and at the other end. The feeding mechanism includes a feeding roller and a feeding motor connected to the feeding roller. The cutting mechanism includes a main shaft, a fixed frame, and several cutting blades mounted on the fixed frame. The cutting blades are bolted to the fixed frame. The coating mechanism includes a coating roller and a coating die. The discharging mechanism includes a discharging roller and a discharging motor connected to the discharging roller. A waste suction mechanism is also provided on the side of the frame near the feeding shaft. The waste suction mechanism includes air ducts, a waste motor, and a waste bin located on both sides of the cutting mechanism. One side of the air duct is connected to the waste motor, and the other side of the waste motor is connected to the waste bin.

[0006] Preferably, the coating head includes a bottom mold and a plurality of dispensing heads disposed on the bottom mold. The bottom mold is also provided with a drive motor and a glue storage tank. The glue storage tank is also provided with a drive pump. The drive pump is connected to the dispensing heads through a delivery pipe.

[0007] Preferably, the drive pump is a gear pump.

[0008] Preferably, a heating plate mounted on a frame is provided below the coating roller.

[0009] Preferably, the heating plate includes a plurality of heating tubes and a power supply electrically connected to the heating tubes.

[0010] Preferably, the heating tube is U-shaped.

[0011] Preferably, a first spreading roller is provided between the feeding mechanism and the coating roller, and a second spreading roller is provided between the coating roller and the discharging mechanism.

[0012] Preferably, a degumming roller is also provided between the second unfolding roller and the discharge mechanism, and the degumming roller is provided with a spiral pattern.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By combining a cutting blade with a waste suction mechanism, high-barrier film coating can be applied simultaneously with slitting, and waste can be effectively recycled. The waste suction mechanism reduces material waste and keeps the working environment clean. The simultaneous execution of the two processes greatly improves production efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an online coating device for high-barrier films, including a frame 1, a feeding mechanism 2, a cutting mechanism 3, a coating mechanism 4, and a discharging mechanism 5. The feeding mechanism 2 is provided at one end of the frame 1, and the discharging mechanism 5 is provided at the other end. The feeding mechanism 2 includes a feeding roller 6 and a feeding motor 7 connected to the feeding roller 6. The cutting mechanism 3 includes a main shaft 8, a fixed frame 9, and a plurality of cutting blades 10 provided on the fixed frame 9. The cutting blades 10 are bolted to the fixed frame 9. The coating mechanism 4 includes a coating roller 11 and a coating die head 12. The discharging mechanism 5 includes a discharging roller 13 and a discharging motor 14 connected to the discharging roller 13. A waste suction mechanism 15 is also provided on the side of the frame 1 near the feeding shaft. The waste suction mechanism 15 includes an air duct 16, a waste motor 17, and a waste bin 18 provided on both sides of the cutting mechanism 3. One side of the air duct 16 is connected to the waste motor 17, and the other side of the waste motor 17 is connected to the waste bin 18.

[0025] Specifically, the coating die head 12 includes a bottom mold 19 and a plurality of dispensing heads 20 disposed on the bottom mold 19. The bottom mold 19 is also equipped with a drive motor 21 and a glue storage tank 22. The glue storage tank 22 is also equipped with a drive pump 23. The drive pump 23 is connected to the dispensing heads 20 through a delivery pipe 24. Through the above configuration, the coating die head 12 can accurately control the flow rate of glue and the uniformity of coating. The surface of the coating roller 11 is also specially processed to ensure the adhesion and uniformity of the coating layer.

[0026] Furthermore, the drive pump 23 is configured as a gear pump. By configuring the drive pump 23 as a gear pump, the gear pump can withstand the huge pressure and friction generated by the high viscosity glue during the pumping process without easily experiencing wear or deformation.

[0027] Specifically, a heating plate 25 mounted on the frame 1 is provided below the coating roller 11. Furthermore, the heating plate 25 includes several heating tubes 26 and a power supply 27 electrically connected to the heating tubes 26. Furthermore, the heating tubes 26 are U-shaped. Through the above arrangement, the heating plate 25 can uniformly heat the coating roller 11, thereby ensuring that the coating material reaches the ideal temperature during the coating process, so as to improve the coating quality and efficiency.

[0028] Specifically, a first spreading roller 28 is provided between the feeding mechanism 2 and the coating roller 11, and a second spreading roller 29 is provided between the coating roller 11 and the discharging mechanism 5. By providing the first spreading roller 28 and the second spreading roller 29, the film can achieve better tension control and stability during the coating process. The first spreading roller 28 and the second spreading roller 29 can effectively flatten the film, thereby achieving higher slitting and coating accuracy.

[0029] Furthermore, a glue-removing roller 30 is also provided between the second unfolding roller 29 and the discharge mechanism 5. The glue-removing roller 30 has a spiral pattern. By providing the glue-removing roller 30, the spiral pattern can effectively remove excess glue generated during the coating process, ensuring coating quality. The spiral pattern design of the glue-removing roller 30 can increase the contact area with the film, thereby improving the glue removal efficiency.

[0030] A specific application example of this embodiment is as follows:

[0031] When using this device, the user first installs the film on the feeding roller 6. The feeding motor 7 drives the feeding roller 6 to rotate, ensuring that the film enters the cutting mechanism 3 smoothly. The main shaft 8 drives the cutting blade 10 to cut the film to meet the coating requirements of different sizes. The cut film passes through the first unfolding roller 28 and then enters the coating mechanism 4. The coating roller 11 and the coating die head 12 work together to evenly coat the film surface with glue. During the coating process, the drive motor 21, glue storage tank 22, and drive pump 23 inside the coating die 12 ensure a continuous supply of glue and guarantee the uniformity of the coating layer. The special processing of the coating roller 11 helps to improve the adhesion of the coating layer and ensure the coating quality. The coated film is heated under the action of the heating plate 25. The U-shaped heating tube 26 of the heating plate 25 is connected to the power supply 27 to ensure that the coating material reaches the ideal temperature during the coating process, thereby improving the coating quality and efficiency. Under the action of the first spreading roller 28 and the second spreading roller 29, the coated film obtains better tension control and stability, and flattens the film to improve the cutting and coating accuracy. The spiral pattern on the glue removal roller 30 effectively removes excess glue generated during the coating process and ensures the coating quality.

[0032] Finally, the precisely coated and processed film is output through the discharge mechanism 5, and the discharge motor 14 drives the discharge roller 13 to smoothly deliver the film out of the device. The entire coating process achieves high-efficiency and high-quality coating, suitable for various applications requiring films with high barrier properties.
