[0035] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0036] See Figure 1 , Figure 1 The accompanying drawing shows a structural schematic diagram of a double-sided coating device according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0037] In this embodiment, a double-sided coating device is provided, including a frame 1, two oppositely arranged coating mechanisms 2, a silicone oil feeding mechanism 3, a substrate 4, a guide roller 5, an oven device 6, and a receiving basin 7; wherein, the frame 1 serves as the supporting structure of the entire device, ensuring that each component can be stably installed and operated.

[0038] Combination Figure 2 , Figure 2 A schematic diagram of the coating mechanism 2 in one embodiment of the present invention is shown.

[0039] In one embodiment, each coating mechanism 2 includes a drive element 21, a guide rail 22, a slider 23, a mounting base 24, a steel roller 25, and a rubber roller 26;

[0040] The driving component 21 is preferably a hydraulic cylinder structure, used to provide driving force;

[0041] The guide rail 22 is fixed on the frame 1, the slider 23 slides with the guide rail 22, and the output end of the drive unit 21 drives the slider 23 to move along the length of the guide rail 22.

[0042] The mounting base 24 is fixed on the slider 23, and the coating roller assembly is assembled on the mounting base 24.

[0043] In one specific embodiment, the coating roller assembly consists of multiple abutting coating rollers arranged with steel rollers 25 and rubber rollers 26 spaced apart. Specifically, the coating rollers abutting both sides of the substrate 4 are rubber rollers 26 to ensure the uniformity and stability of the coating and to protect the surface of the substrate 4 from scratches. Furthermore, the two outermost rubber rollers 26 that abut both sides of the substrate 4 rotate in opposite directions, thereby achieving simultaneous coating of both sides of the substrate 4 from both sides and driving the substrate 4 into the drying oven 6.

[0044] In one embodiment, a silicone oil feeding mechanism 3 is positioned above the coating mechanism 2 to cover the coating roller assembly within the coating mechanism 2 with silicone oil. The silicone oil feeding mechanism 3 employs a funnel-shaped feeding structure that narrows from wide to narrow, ensuring that the silicone oil is evenly distributed across the coating roller. A solenoid valve is located at the outlet of the feeding structure to control the opening and closing of the outlet, thereby precisely controlling the amount of silicone oil fed. The solenoid valve is electrically connected to a controller, enabling automated control.

[0045] In one embodiment, the guide roller 5 abuts against the substrate 4, and the guide roller 5 is used to guide the substrate 4 through the two coating mechanisms 2.

[0046] In one embodiment, the drying oven 6 is located after the coating mechanism 2 and is used to dry the substrate 4 after coating to ensure the curing of the coating layer.

[0047] In one embodiment, the controller (not shown) is electrically connected to the drive unit 21 and the coating roller assembly to achieve automated control of the entire device. For example, the controller can control the drive unit 21 to drive the two coating mechanisms 2 to synchronously approach each other until the coating rollers come into contact with the substrate 4, and the coating operation begins. Simultaneously, the controller can also control the rotation of the coating rollers in the coating roller assembly and the opening and closing of the solenoid valve of the silicone oil feeding mechanism 3, thereby precisely controlling the coating process and the amount of silicone oil fed.

[0048] In one embodiment, a receiving basin 7 is provided below each coating mechanism 2 to collect excess silicone oil. In actual operation, the length and width of the receiving basin 7 can be changed according to the size of the coating mechanism 2, so that the length and width of the receiving basin 7 can always cover the oil dripping position below the coating mechanism 2. The structural design of the receiving basin 7 in this application not only improves the utilization rate of silicone oil, but also reduces environmental pollution.

[0049] In practice, the working method of this application is as follows:

[0050] The substrate 4 passes between the two coating mechanisms 2 after being guided by the guide roller 5;

[0051] The driving component 21 drives the slider 23 to move along the guide rail 22, so that the coating roller assemblies on both sides abut against the substrate 4;

[0052] The silicone oil feeding mechanism 3 covers the coating roller with silicone oil, and the coating roller evenly coats the silicone oil onto both sides of the substrate 4;

[0053] After coating, the substrate 4 is placed in the drying oven 6 for drying.

[0054] Throughout the process, the controller achieves automated control, ensuring the accuracy and stability of the coating operation.

[0055] The double-sided coating apparatus of this application enables simultaneous coating of both sides of the substrate 4, greatly improving coating efficiency, reducing production cycle, and avoiding the risk of scratching the substrate 4. Furthermore, the apparatus has a compact and reasonable structure, facilitates the coating process, and has broad application prospects.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
