[0002] In the modern pharmaceutical and medical device sectors, glassine paper is widely used in the production of pharmaceutical packaging, medical dressings, and other medical materials due to its excellent anti-stick and water-repellent properties. Glassine paper is a paper material coated with silicone oil on a specific substrate, resulting in a smooth surface and excellent release properties. To ensure its performance in various applications, the production process places high demands on the silicone oil's coating quality, uniformity, and curing speed.

[0028] A silicone oil discharge pipe 55 is fixedly mounted on the bottom of the protective housing 52 .

[0029] The smearing structure 6 includes a connecting frame 61, a smearing roller 62, an upper heating roller 63, a lower support roller 64 and a gear box 65, and the connecting frame 61 is fixedly installed on a section of the support frame 2 that outputs glassine paper outward, and the smearing roller 62 is rotatably installed at the front end of the connecting frame 61; the upper heating roller 63 is rotatably installed above the rear end of the connecting frame 61, and the lower support roller 64 is rotatably installed below the rear end of the connecting frame 61.

[0030] The protective shell 52 inside the coating unit 5 adopts a stainless steel metal trough with an open upper end, and glassine paper passes through the upper middle part of the protective shell 52. The support unit plate 53 adopts three groups of steel metal plates; the support unit plate 53 is located above the glassine paper, and silicone oil nozzles 54 are provided inside the support unit plates 53; the silicone oil nozzles 54 are arranged in a one-two-one manner on the three groups of support unit plates 53.

[0031] The coating roller 62, the upper heating roller 63 and the lower support roller 64 inside the coating structure 6 rotate accordingly with the movement of the glassine paper; the outer side of the coating roller 62 is wrapped with a layer of high-density sponge pad; the upper heating roller 63 is provided with a heating wire inside, and the upper heating roller 63 contacts the side of the glassine paper sprayed with silicone oil.

[0032] The operating principle of the single-sided coating equipment for pharmaceutical glassine paper is to evenly apply silicone oil to one side of the glassine paper through a precise coating and heating process, achieving ideal protection and release properties. The equipment primarily consists of a support base, a support frame, a coating unit, and an application mechanism. The following is a detailed description of the equipment's workflow and principles.

[0033] 1. Overview of equipment structure

[0034] Support base 1: The basic supporting part of the equipment, bearing the weight and operation of the entire device.

[0035] Support frame 2: A structure fixed on the support base 1 to support the installation and stability of various components in the equipment.

[0036] Coating unit 5: The core part used for spraying silicone oil, which contains multiple functional components.

[0037] Coating structure 6: The sprayed silicone oil is evenly coated and solidified through structures such as a coating roller and a heating roller.

[0038] 2. Workflow

[0039] Material input:

[0040] Glassine paper is fed into the device through the input roller 3, and the rotation of the input roller 3 drives the paper forward to ensure the flatness and stability of the paper.

[0041] Silicone oil spraying:

[0042] The glassine paper enters the coating unit 5, and the silicone oil nozzle 54 sprays the silicone oil evenly on one side of the paper. The design of the nozzle allows the silicone oil to cover the entire surface to meet the requirements of medical use.

[0043] Smearing and homogenization:

[0044] The sprayed glassine paper continues to move forward and enters the coating structure 6. During this process, the coating roller 62 further distributes the silicone oil evenly on the surface of the paper through its high-density sponge pad. The coating roller 62 rotates with the movement of the paper to ensure that the coating thickness in each area is consistent.

[0045] Heat curing:

[0046] Subsequently, the glassine paper passes through the upper heating roller 63. The heating wire inside the upper heating roller 63 provides the required heat to quickly solidify the silicone oil. This process not only improves the adhesion of the coating, but also enhances its durability and protective effect.

[0047] Support and guidance:

[0048] The lower support roller 64 provides additional support to ensure that the paper remains flat during the coating and heating process to avoid any wrinkles or deformation. At the same time, the lower support roller 64 works in conjunction with the upper heating roller 63 to ensure smooth movement of the paper during the coating process.

[0049] Material output:

[0050] After coating and curing, the glassine paper is sent out of the device through the output roller 4 and is ready for subsequent processing or packaging.

[0051] 3. System control and monitoring

[0052] The gearbox 65 within the device is used to control the rotation speed of each roller, ensuring that they are synchronized with the movement of the glassine paper, ensuring the efficiency and consistency of the entire coating process.

[0053] 4. The role of protective shell

[0054] The protective shell 52 surrounds the coating unit, which can collect excess silicone oil to prevent it from scattering into the external environment, and recycle and reuse the excess silicone oil through the silicone oil discharge pipe 55, thereby improving the environmental protection and economy of the equipment.

[0055] in conclusion

[0056] Through precise design and efficient workflow, the single-sided coating equipment for pharmaceutical glassine paper achieves spraying, uniform application, and rapid curing of silicone oil, ensuring high quality and consistency of the final product. Furthermore, the equipment design also takes environmental protection and resource recycling into consideration, improving production efficiency and meeting the needs of modern industrial production.

[0057] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
