Common release film materials include polyethylene terephthalate, polyethylene, polypropylene, polyvinyl chloride, etc.

[0003] Coating a release agent onto a thin film is a common processing method for release films, which can improve the performance of the release film and increase its functions.

Specific embodiments

[0034] The technical solutions of the present invention will be further described in detail below through embodiments in conjunction with the drawings, but the present invention is not limited to the following embodiments.

[0035] The release film is a thin film material used for packaging, protecting or separating items. It usually has functions such as waterproof, dustproof, and anti-static, and can effectively protect items from the influence of the external environment. Release films are widely used in fields such as food packaging, pharmaceutical packaging, and electronic product packaging. Common release film materials include polyethylene terephthalate, polyethylene, polypropylene, polyvinyl chloride, etc.

[0036] Coating a mold release agent onto a thin film is a common processing method, which can improve the performance of the thin film and increase its functions. By coating a layer of mold release agent on the surface of the thin film, the wear resistance, waterproofness, and chemical corrosion resistance of the thin film can be increased. At the same time, the friction between the thin film and the adherend can be reduced, making it easier to peel off. This treatment method is usually used to prepare high-performance special-purpose release films, such as release films for electronic product encapsulation and release films for medical use. Coating a mold release agent onto a thin film requires professional equipment and technology to ensure uniform coating and firm adhesion.

[0037] If the mold release agent is unevenly coated on the thin film, it may cause the surface of the coating to be uneven, affecting the appearance and quality of the product. Uneven coating may also result in inconsistent adhesion of the mold release agent on the surface of the thin film, making the adhesion performance of the thin film unstable during use and prone to peeling or falling off.

[0038] To solve the above problems, the object of the present invention is to provide a release agent directional vibration coating device for coating a release agent on the surface of a material tape 13; the release agent directional vibration coating device includes: a synchronous belt 10 running synchronously with the material tape 13, a vibration device connected to the synchronous belt 10, and a spraying assembly for spraying the release agent on the surface of the material tape 13;

[0039] One side of the material tape 13 is in contact with the outer surface of the synchronous belt 10, the spraying assembly is arranged on the other side of the material tape 13, and the vibration device is arranged on the inner surface of the synchronous belt 10. The vibration device can drive the synchronous belt 10 in contact with the material tape 13 to vibrate; in the state where the synchronous belt 10 and the material tape 13 run synchronously, the spraying device can spray the release agent on the surface of the material tape 13, and the vibration device generates vibration to disperse the release agent on the surface of the material tape 13.

[0040] In this embodiment, as Figure 1 、 Figure 2 shown, the material tape 13 is a coil that needs to be coated with a release agent. The material tape 13 can be a tape, and a release agent is coated on one side of the tape. The material tape 13 is unfolded, the synchronous belt 10 is arranged on one side of the material tape 13, the synchronous belt 10 runs in a loop, a part of the synchronous belt 10 is attached to the bottom of the material tape 13, the spraying assembly is arranged above the material tape 13, the spraying assembly sprays the atomized release agent onto the upper surface of the material tape 13, and the vibration device drives the part of the synchronous belt 10 area attached to the material tape 13 to vibrate. The synchronous belt 10 transmits the vibration energy to the material tape 13, and then the liquid release agent is evenly distributed on the surface of the material tape 13 by vibration. Vibration can make the thicker liquid release agent automatically spread around and finally become flat to ensure the flat coating of the release agent.

[0041] Further, the spraying assembly includes a main pipeline 11 and a plurality of branch pipelines 12 connected to the main pipeline 11. The plurality of branch pipelines 12 are distributed along the width direction of the material tape 13; the main pipeline 11 and the branch pipelines 12 are arranged above the material tape 13, and the branch pipelines 12 are inclined forward in the moving direction of the material tape 13;

[0042] The end of the branch pipeline 12 is provided with a spray head, and the spray head can atomize the release agent. After atomization, the release agent becomes small particles and then adheres to the surface of the material tape 13.

An atomizing nozzle 14 is provided at the end of the branch pipeline 12 close to the material belt 13. The main pipeline 11 is connected to the input source of the liquid release agent, and the input liquid release agent has pressure. The liquid release agent in the main pipeline 11 is split into each branch pipeline 12 and then sprayed out from the atomizing nozzle 14 at the head of the branch pipeline 12.

[0044] Since the branch pipeline 12 extends obliquely downward along the running direction of the material belt 13, the liquid release agent is atomized into granular form and adheres to the material belt 13 in a fine oval sphere shape. The vibration device can quickly shake off the liquid release agent particles and form a uniform and flat release agent coating on the surface of the material belt 13.

The vibration unit 42 is arranged on the contact plate 41, and the contact plate 41 can balance the vibration energy generated by multiple vibration units 42, so that the vibration generated by multiple vibration units 42 is evenly distributed on the contact surface between the contact plate 41 and the synchronous belt 10, avoiding strong vibration in some areas close to the vibration unit 42 and weak vibration in some areas far from the vibration unit 42.

Therefore, they are widely used in fields such as sensors, transducers, and acoustic wave devices. Piezoelectric ceramics have the advantages of high stability, fast response speed, and low power consumption, and are an important functional ceramic material.

[0060] Piezoelectric ceramics can generate vibrations by applying an electric field. When a voltage is applied to the piezoelectric ceramic, it will cause a change in its internal lattice structure, thereby causing a change in the size of the material. This size change will cause the material to generate mechanical vibrations, that is, the piezoelectric effect. By controlling the frequency and amplitude of the applied voltage signal, the frequency and amplitude of the vibrations generated by the piezoelectric ceramic can be controlled.
