Description

Technical Field

[0001] This invention relates to the field of surface spraying, and in particular to a spraying and printing process for glass bottles. Background Technology

[0002] Spray coating and printing processes on the surface of glass wine bottles can significantly alter their appearance, creating a remarkable aesthetic effect that benefits product marketing. Currently, spray coating processes simply involve applying colored paint to untreated bottle surfaces. As a result, over time, the colors fade and the prints peel off, thus reducing the product's value. Summary of the Invention

[0003] The purpose of this application is to provide a glass bottle spray printing process to solve the problems existing in the prior art.

[0004] This application provides a glass bottle spray printing process, including the following steps:

[0005] S1. Grind and clean the sprayed areas on the surface of the glass bottle. First, use coarse sandpaper to grind the areas, and then use a high-pressure water gun to rinse and clean the ground areas of the glass bottle to remove the grinding powder.

[0006] S2. Place the glass bottle in a flame gun for flame treatment, raising the surface temperature to 60°C; spray a 0.1 mm thick PVC fiber undercoat onto the surface of the glass bottle, then place it back in the flame gun to raise the surface temperature to 100°C and hold for 30 seconds. After that, remove the bottle and quickly apply a second coat of PVC fiber undercoat, with a thickness of 0.1-0.2 mm. Allow the bottle to cool naturally to 55°C after the second coat is applied.

[0007] S3. Screen printing is performed on the sprayed area. UV ink is used in the screen printing machine to print on the sprayed area. After printing, a UV curing machine is used to cure it.

[0008] S4. After curing, apply a third coat and use glitter to seal the printed area.

[0009] Furthermore, the grit size of the sandpaper is 40-100 mesh.

[0010] Furthermore, in step S2, the surface temperature of the glass bottle is maintained at 100-80℃ during the second spraying.

[0011] Furthermore, in step S3, the UV curing machine uses LED UV curing lamps.

[0012] Furthermore, in step S4, the glitter content used in the third spray is 0.1 mg per square centimeter.

[0013] Further, after the sealing process, all glass bottles undergo a full inspection, and qualified products are collected, packaged, and stored.

[0014] The beneficial effects of this invention are as follows: By pre-treating the glass bottle body to increase its roughness, and then spraying a base coat of PVC fiber that melts at high temperatures, the base coat can fully bond with the bottle body, improving stability. The second base coat not only enhances adhesion to the bottle body but also further roughens the surface, facilitating the fixation of the printed paint. Finally, a glitter sealing layer creates a unique visual effect on the bottle's exterior, which is beneficial for the product's market promotion. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the overall process of the present invention. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] A glass bottle spray printing process includes the following steps:

[0018] S1. Grind and clean the areas of the glass bottle surface to be coated. First, use coarse sandpaper (40-100 grit) to roughen the smooth glass surface, which will facilitate the adhesion of the paint and increase its bonding strength. Then, use a high-pressure water gun to rinse and clean the ground areas of the glass bottle surface to remove grinding powder and make the bottle surface clean.

[0019] S2. Place the glass bottle in a flame gun for flame treatment, raising the surface temperature to 60°C. Spray a PVC fiber base coat onto the glass bottle surface. Preheat the glass surface to facilitate the adhesion of the sprayed PVC to the bottle surface. The thickness of the base coat is 0.1 mm. Then place it in the flame gun for treatment, raising the surface temperature to 100°C and holding for 30 seconds. This melts the PVC fiber and allows it to adhere and fuse with the rough glass bottle surface, enhancing the adhesion between the base coat and the glass bottle.

[0020] Then, quickly remove the bottle and apply a second coat of PVC fiber, creating a second base coat. During the second coat, maintain the glass bottle surface temperature at 80-100°C. The thickness of the PVC fiber base coat should be 0.1-0.2 mm. At this temperature, the PVC fibers melt rapidly upon contact with the bottle, while the fibers not in contact with the bottle remain intact, allowing the second base coat to bond with the first and creating a rougher surface. After spraying, allow the bottle to cool naturally to 55°C to cure the two layers of PVC fiber.

[0021] S3. Perform screen printing on the sprayed areas. The screen printing process is the same as the existing process and can be done using a conventional screen printing machine. Use UV ink in the screen printing machine to print on the sprayed areas, and then use a UV curing machine for curing after printing. The UV curing machine uses LED UV curing lamps, and the exposure is the same as in the conventional process.

[0022] S4. After curing, apply a third coat of glitter to seal the printed area. The glitter content is 0.1 mg per square centimeter, giving the printed area a special shimmering visual effect.

[0023] After the sealing process, all glass bottles undergo a full inspection, and qualified products are collected, packaged, and stored.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
