Technical Field

[0001] The utility model relates to the field of release paper, in particular to a release paper coating device. Background Art

[0002] Release paper, also known as silicone paper, anti-adhesive paper or isolation paper, is a kind of paper with special coating, usually coated with silicone oil or other anti-adhesive substances on one side, used to isolate sticky substances such as tapes, labels, films, etc. The main function of release paper is to prevent these products from sticking to each other or other objects during production, transportation and storage.

[0003] When applying silicone oil to the surface of release paper, a roller is generally used for brushing, with the lower end of the roller in a container containing silicone oil and the upper end directly in contact with the release paper. In this process, the roller rotates to make its surface stained with silicone oil, and then it is applied to the release paper. However, in the process of application, there are still the following defects and shortcomings: the silicone oil on the roller is not uniform, so when it is brushed on the release paper, it is not evenly applied, which affects the brushing effect.

[0004] Therefore, it is necessary to provide a new release paper coating device to solve the above technical problems. Utility Model Content

[0027] In the description of the present invention, "plurality" means two or more than two, unless otherwise clearly and specifically defined.

[0028] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0031] See also Figures 1 to 4 The present invention provides a release paper coating device, which includes a mounting frame 1, a storage tank 3 on the mounting frame 1, and silicone oil is loaded in the storage tank 3, and further includes:

[0032] The conveying rollers 2 are in two groups, symmetrically mounted on the mounting frame 1 at positions away from the center. Each group of conveying rollers 2 is composed of two conveying rollers arranged one above the other, with a gap between the two conveying rollers 2, and the release paper passes through the gap.

[0033] A paint brush roller 4 rotates inside the mounting frame 1 and is located inside the storage tank 3. A sponge 6 is sleeved on the outside of the paint brush roller 4. A motor 5 for driving the paint brush roller 4 to rotate is also disposed outside the mounting frame 1.

[0034] The adjusting member 8 is installed inside the mounting frame 1 . A scraper 9 is fixed on the adjusting member 8 , and the silicone oil applied on the release paper is scraped flat by the scraper 9 .

[0035] It should be noted that: in this coating device, the storage tank 3 on the mounting frame 1 is used to contain silicone oil, and the conveying rollers 2 arranged at both ends are used to automatically convey the release paper, thereby improving the coating efficiency of the release paper;

[0036] It should also be noted that: the brush roller 4 rotates inside the storage tank 3, and a sponge 6 is also provided outside the brush roller 4, so during the rotation process, the sponge 6 can be used to absorb the silicone oil. In this state, it is not necessary to ensure that each area absorbs the silicone oil uniformly, but only needs to absorb the silicone oil at each position. Then, during the rotation, the silicone oil can be brushed onto the release paper to achieve a preliminary coating process;

[0037] It should also be noted that an adjusting member 8 is also provided on the mounting frame 1, and a scraper 9 is installed on the adjusting member 8. The scraper 9 can directly contact the release paper, so as to scrape the silicone oil coated on the release paper evenly to ensure the uniformity of the silicone oil, which greatly improves the coating effect. The scraper 9 can also scrape off the excess silicone oil, and the scraped silicone oil falls into the storage tank 3 again, so there will be no waste of silicone oil. The height of the scraper 9 can be changed by the adjusting member 8, so that the thickness of the silicone oil coated on the release paper can be changed.

[0038] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 A squeezing roller 7 is also rotated in the mounting frame 1 and located inside the storage tank 3 , and the sponge 6 outside the conveying roller 2 is squeezed by the squeezing roller 7 .

[0039] It should be noted that the squeezing roller 7 is set for the sponge 6, which is located inside the storage tank 3 and can squeeze the sponge 6, thereby squeezing out the air in the sponge 6 to ensure that the sponge 6 can absorb the silicone oil and ensure that the silicone oil subsequently applied to the release paper is just enough.

[0040] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 , the adjusting member 8 comprises:

[0041] The positioning frame 81 is in two sets and is bolted to the inside of the mounting frame 1;

[0042] The screw rod 82 is rotated on one of the positioning frames 81, a handle 83 is fixed to one end of the screw rod 82, and a transmission frame 84 is also transmission-connected to the screw rod 82;

[0043] A light rod 86 is fixed on another positioning frame 81, and a slide 87 is slidably connected to the light rod 86;

[0044] A mounting plate 85 is fixed on both the transmission frame 84 and the slide frame 87 , and the scraper 9 is fixed on the mounting plate 85 by bolts.

[0045] It should be noted that when the adjusting member 8 is in use, the turning handle 83 is directly rotated, which can directly drive the screw rod 82 to rotate, thereby driving the transmission frame 84 and the mounting plate 85 to move in the vertical direction, and the scraper 9 is fixed on the mounting plate 85, which can drive the scraper 9 to move in the vertical direction to adjust the height of the scraper 9, and the polished rod 86 can further improve the stability of the entire structure;

[0046] In the present embodiment, the lower end of the screw rod 82 is a smooth rod body, which passes through the mounting frame 1 and is located inside the storage tank 3, so the sealing performance of this position should be ensured to avoid leakage.

[0047] In the embodiments of the present invention, please refer to Figure 4 The scraper 9 is V-shaped, and its opening faces the position of the conveying roller 2 for inputting the release paper.

[0048] It should be noted that this arrangement can better gather the excess silicone oil scraped off by the scraper 9 , so that the silicone oil falls into the storage tank 3 .

[0049] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0050] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
