Description

Technical Field

[0001] The utility model belongs to the technical field of paint spraying, and in particular relates to a protective sticker for paint spraying. Background Art

[0002] When spraying paint on a plastic shell, it is often necessary to mask the part that is not to be painted. There are two common masking methods in the prior art: the first is to use a jig for masking. This method requires that the jig fits well with the periphery of the required masking area, which requires high jig precision. If the fit is not good, oil flying will occur, resulting in poor product appearance. The second method is to use tape or paper for masking. This method often requires repeated adjustment of the tape's position, resulting in low efficiency of the painting operation.

[0003] Therefore, it is necessary to design a protective sticker that can shield the parts of the workpiece to be painted that are not to be painted and has high operating efficiency. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the present invention provides a paint spraying protective sticker.

[0005] The technical solution adopted by the utility model is:

[0006] A paint spraying protective film is used to cover the part of the workpiece to be sprayed with paint, and includes a positioning film, a handle film, a shielding film and a sticky protective film which are sequentially adhered from top to bottom;

[0007] The edge of the positioning film exceeds the shielding film, and a positioning hole is provided in the exceeding portion; the positioning hole is used for aligning the shielding film with the part of the workpiece to be painted which is not to be sprayed with paint;

[0008] The lower surface of the shielding film can be adhered to the part of the workpiece to be painted where paint is not to be sprayed, and can be torn off together with the handle film.

[0009] As an alternative or supplement to the above paint spraying protective sticker: a handle tongue for holding is formed in the middle of the handle film, the edge of the handle film is adhered to the shielding film, and the handle tongue is not adhered to the shielding film.

[0010] As an alternative or supplement to the above paint spraying protective film: a handle shielding film is provided between the handle and the upper surface of the shielding film, and the handle shielding film is used to prevent the handle from adhering to the upper surface of the shielding film.

[0011] As an alternative or supplement to the above paint spraying protective sticker: an H-shaped through seam is opened on the handle film to form the handle tongue.

[0012] As an alternative or supplement to the paint spraying protective film, the adhesive protective film is adhered to the lower surface of the shielding film and the lower surface of the portion of the positioning film that extends beyond the shielding film.

[0013] As an alternative or supplement to the above paint spraying protective film: the adhesion between the adhesive protective film and the shielding film and the adhesion between the positioning film and the adhesive protective film are smaller than the adhesion between the positioning film and the handle film.

[0014] As an alternative or supplement to the above paint spraying protective film: the viscosity of the lower surface of the shielding film is less than that of the upper surface, so that the shielding film can be torn off the workpiece to be painted together with the handle film.

[0015] As an alternative or supplement to the above paint spraying protective film: the positioning film and the adhesive protective film are both rectangular film structures of the same size.

[0016] The beneficial effects of the utility model are as follows: in this scheme, through the positioning of the positioning film, the shielding film can be used to effectively position the parts of the workpiece to be painted that are not sprayed with paint. This is suitable for scenes where the painting operation has strict requirements on the position and size of the product shielding area, and effectively improves the work efficiency of the shielding operation. In addition, this scheme protects the product shielding area by sticking the shielding film, which can ensure better fit, avoid paint flying, and ensure the yield rate of product appearance.

[0020] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0021] Example 1

[0022] like Figure 1As shown, this embodiment designs a paint spraying protective sticker for shielding the parts of the workpiece to be painted that are not sprayed with paint, including a positioning film 1, a handle film 2, a shielding film 4, a handle and tongue shielding film 3 and an adhesive protective film 5 and other structures.

[0023] Before use, the positioning film 1, the handle film 2, the shielding film 4, the handle and tongue shielding film 3 and the adhesive protective film 5 are bonded in sequence from top to bottom.

[0024] The positioning film 1 is a thin film structure and can be in a rectangular shape. The material of the positioning film 1 can be PET. The thickness of the positioning film 1 can be 0.1 mm. Silicone adhesive is coated on the lower surface of the positioning film 1 to facilitate the adhesion of the positioning film 1 to the handle film 2 and the sticky protective film 5. After tearing off the sticky protective film 5, it is also convenient to attach the positioning film 1 to the workpiece to be painted.

[0025] The edge of the positioning film 1 extends beyond the shielding film 4, and a positioning hole 11 is provided in the extending portion; the positioning hole 11 is used for aligning the shielding film 4 with the portion of the workpiece to be painted where paint is not sprayed; specifically, the positioning hole 11 can be aligned with a protrusion on the workpiece to be painted, or the positioning hole 11 can be positioned on a corresponding fixture and aligned with the fixture.

[0026] The lower surface of the shielding film 4 can be pasted to the part of the workpiece to be painted when in use, and can be torn off together with the handle film 2. Before use, the shielding film 4 is pasted together with the sticky protective film 5, so that the stickiness of the shielding film 4 is protected by the sticky protective film 5.

[0027] A handle tongue 21 for holding is formed in the middle of the handle film 2, and the edge of the handle film 2 is adhered to the shielding film 4, while the handle tongue 21 is not adhered to the shielding film 4. A handle tongue shielding film 3 is provided between the handle tongue 21 and the upper surface of the shielding film 4, and the handle tongue shielding film 3 is used to prevent the handle tongue 21 from adhering to the upper surface of the shielding film 4. An H-shaped through seam can be provided on the handle film 2 to form the handle tongue 21. The material of the handle film 2 can be PET, and the thickness of the handle film 2 can be 0.08 mm. The four feet of the H-shaped through seam can be set to be hook-shaped to prevent the root of the handle tongue 21 from being torn.

[0028] The adhesive protective film 5 adheres to the lower surface of the shielding film 4 and the lower surface of the positioning film 1 beyond the shielding film 4. The adhesion between the adhesive protective film 5 and the shielding film 4 and the adhesion between the positioning film 1 and the adhesive protective film 5 is less than the adhesion between the positioning film 1 and the handle film 2.

[0029] The viscosity of the lower surface of the shielding film 4 is lower than that of the upper surface, so that the shielding film 4 can be torn off the workpiece to be painted together with the handle film 2 .

[0030] When the paint spraying protective sticker in this embodiment is used: the sticky protective film 5 can be torn off first, and then the positioning film 1 can be positioned on the corresponding fixture or on the workpiece to be painted through the positioning hole 11, and then the positioning film 1 can be covered on the workpiece to be painted. At this time, the shielding film 4 and the part of the workpiece to be painted that is not to be sprayed with paint are matched and shielded, and then the positioning film 1 can be torn off to carry out the paint spraying operation. After the spraying operation is completed, the handle tongue 21 on the handle film 2 is tilted up, and the worker will grasp the handle tongue 21 to tear off the shielding film 4 and the handle film 2.

[0031] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
