Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, specifically to a coating device for processing acrylic foam tape. Background Technology

[0002] Acrylic foam tape is made of high-density acrylic foam substrate, which has excellent bonding strength and good sealing performance. During the production of acrylic foam tape, an applicator is used to apply adhesive to it.

[0003] Existing coating devices for acrylic foam tape processing lack a mechanism to scrape off excess adhesive from the tape when applying adhesive. This results in uneven adhesive application, affecting tape quality. Furthermore, the contact area between the adhesive and the tape (substrate) is small. Application is typically done via a roller, where only one line contacts the substrate, which easily leads to uneven application and impacts production quality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a coating device for processing acrylic foam tape, which increases the contact area between the adhesive and the substrate and can perform multiple coating and scraping operations, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: an applicator for processing acrylic foam tape, comprising a long strip-shaped shell and a substrate, a bottom plate at one end of the shell, the bottom plate being parallel to the shell and forming a channel for the substrate to pass through between the bottom plate and the shell, the substrate being disposed in the channel, multiple first scrapers and second scrapers being installed inside the shell, and a baffle being installed inside the shell, a liquid storage chamber being formed between the first scraper facing the baffle and the baffle, and a collection chamber being formed between adjacent first scrapers.

[0006] As a preferred technical solution, the height of the first scraper is higher than that of the second scraper, and there is a gap between the first scraper, the second scraper and the substrate. One end of the baffle is in contact with the surface of the substrate.

[0007] As a preferred technical solution, one end of the shell forms an arc-shaped clearance portion, and the clearance portion is recessed to form a first notch, while the other end of the shell is recessed to form a second notch.

[0008] As a preferred technical solution, one side of the base plate is bent upward and mounted on the end face of the housing.

[0009] As a preferred technical solution, the height between the base plate and the shell matches the thickness of the substrate, and the width of the shell opening matches the width of the substrate.

[0010] As a preferred technical solution, one end of the substrate is connected to the winding mechanism and the other end is connected to the unwinding mechanism, and the substrate is in a taut state.

[0011] As a preferred technical solution, both the shell and the base plate have smooth surfaces, and both the shell and the base plate are made of stainless steel.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure, and the glue in the liquid storage chamber can enter the space between the second scrapers, the space between the second scraper and the baffle, and the space between the second scraper and the first scraper, so that there are multiple liquid storage areas, which can be used to coat the substrate multiple times and over a large area to ensure the uniformity of the coating. The first scraper can be used to scrape the glue multiple times, and the second scraper can be used to scrape the glue twice to ensure the uniformity and fullness of the glue application, thus avoiding affecting the quality of the tape.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses an acrylic foam tape processing coating device, comprising a long strip-shaped shell 1 and a substrate 2. One end of the shell 1 is provided with a bottom plate 3, which is arranged parallel to the shell 1, and a channel 9 is formed between the bottom plate 3 and the shell 1 for the substrate 2 to pass through. The substrate 2 is disposed in the channel 9. Multiple first scrapers 6 and second scrapers 8 are installed inside the shell 1. A baffle 7 is also installed inside the shell 1. A liquid storage chamber is formed between the first scraper 6 facing the baffle 7 and the baffle 7, and a collection chamber is formed between adjacent first scrapers 6.

[0023] In this embodiment, the height of the first scraper 6 is higher than that of the second scraper 8, and there is a gap between the first scraper 6 and the second scraper 8 and the substrate 2. One end of the baffle 7 is in contact with the surface of the substrate 2.

[0024] The gap between the first scraper, the second scraper and the substrate allows a layer of adhesive to pass smoothly through the first scraper and the second scraper, while excess adhesive can be scraped away by the first scraper and the second scraper.

[0025] In this embodiment, one end of the housing 1 forms an arc-shaped clearance portion 5, and the clearance portion 5 is recessed to form a first notch, while the other end of the housing 1 is recessed to form a second notch 4.

[0026] In this design, after the adhesive is applied to the substrate, the avoidance part prevents the shell from contacting the substrate, thus avoiding damage to the adhesive on the substrate surface.

[0027] In this embodiment, one side of the base plate 3 is bent upward and installed on the end face of the housing 1, so that the housing and the base plate are integrally formed.

[0028] In this embodiment, the height between the base plate 3 and the shell 1 matches the thickness of the substrate 2, and the width of the opening of the shell 1 matches the width of the substrate 2; this allows the surface of the substrate to contact the end face of the baffle, preventing glue from flowing out between the baffle and the substrate.

[0029] In this embodiment, one end of the substrate 2 is connected to the winding mechanism and the other end is connected to the unwinding mechanism. The substrate 2 is in a taut state, so that the substrate can continuously pass through the channel.

[0030] In this embodiment, the surfaces of both the housing 1 and the base plate 3 are smooth, and both the housing 1 and the base plate 3 are made of stainless steel, which reduces friction with the substrate.

[0031] Working principle: During use, the substrate is inserted into the channel from the side, and the glue can be poured into the liquid storage chamber and flow into the space between the adjacent second scrapers, the space between the second scraper and the baffle, and the space between the second scraper and the first scraper, thus creating multiple liquid storage areas. This allows for multiple and large-area application of the substrate. After the substrate is pulled, the first scraper can scrape off the excess glue on the surface of the substrate. The scraped glue re-enters the liquid storage area. After the substrate is removed from the inside of the liquid storage area, it will come into contact with the second scraper. The second scraper can perform a second glue scraping operation, and the scraped glue enters the collection chamber between the scrapers, avoiding waste and increasing the uniformity of glue scraping and application.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
