Description

Technical Field

[0001] This utility model relates to the field of foam processing technology, and in particular to a foam adhesive coating device with a scraping structure. Background Technology

[0002] Foam is a material made from foamed plastic particles, also known as foamed plastic. Its main components are usually polyurethane, polyethylene, and polypropylene. Foam itself is soft and elastic, but in practical applications, it often needs to be connected and fixed to other objects, such as bonding it to electronic product casings, automotive interior parts, and furniture components. Applying adhesive can form a strong bond between the foam and these objects, ensuring that the foam will not detach or shift during use, thus fulfilling its intended functions such as cushioning, sealing, and sound insulation.

[0003] Foam adhesive coating technology is widely used in current industrial production and various related manufacturing fields. However, existing foam adhesive coating methods have many obvious shortcomings, most notably the lack of diverse processing methods and functional deficiencies. From a practical application perspective, whether it's foam adhesive coating for fixing components in electronic product assembly or its use in automotive interior manufacturing, it is constrained by the limitations of existing technologies. The root cause lies in the lack of a corresponding adhesive coating scraping structure. This lack of structure leads to problems such as poor adhesion and uneven appearance in subsequent use. To improve this, a foam adhesive coating device with a scraping structure is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a foam adhesive coating device with a scraping structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foam adhesive coating device with a scraping structure includes a base, a processing platform, an adhesive storage cylinder, and an adhesive dispensing frame. The processing platform has a placement groove for placing foam, and a lifting plate connected to a cylinder is provided in the placement groove. A collection groove is installed on the processing platform. A horizontal screw is provided on the processing platform via two fixed plates and a drive motor. An adhesive scraper is threaded onto the horizontal screw. A vertical screw is provided on the adhesive scraper through a rotating opening. A transmission groove is provided on the processing platform. A rack is provided in the transmission groove. The end of the vertical screw extends into the transmission groove and is connected to the rack through a transmission mechanism. A lower pressure frame is threaded onto the vertical screw.

[0007] Preferably, the transmission mechanism includes a gear mounted on the end of a vertical screw, the gear meshing with a rack.

[0008] Preferably, the base is provided with a ramp, and the collection trough is provided with a mating opening corresponding to the ramp.

[0009] Preferably, limiting rods are provided between the two fixed plates and inside the rotating opening, and the two limiting rods slide through the scraper plate and the lower pressure frame respectively.

[0010] Preferably, the base is equipped with multiple vertical rods, and the ends of the multiple vertical rods are fixedly connected to the bottom wall of the processing platform.

[0011] Preferably, the base is provided with a cylinder, the telescopic end of the cylinder slides through the bottom of the processing platform, and the placement groove is provided with a lifting plate connected to the telescopic end of the cylinder.

[0012] The beneficial effects of this utility model are:

[0013] 1. The horizontal screw drives the scraper to move, which can scrape the accumulated glue level. The lower pressure frame, with the help of gears and racks, will slowly descend as the scraper moves, ensuring uniform glue coating on the foam surface and improving coating quality.

[0014] 2. A ramp and a collection tank are provided. The scraper scrapes excess glue onto the ramp, allowing it to pass smoothly through the fitting port into the collection tank, thus enabling the glue to be recycled and reducing costs.

[0015] 3. The placement slot is equipped with a lifting plate connected to the cylinder. When the foam is placed in, the height is lower than the upper surface of the processing platform to facilitate glue application. After the glue is applied, the cylinder can drive the foam to rise and detach it from the placement slot for easy removal of the foam. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A foam adhesive coating device with a scraping structure includes a base 1, a processing platform 2, an adhesive storage cylinder 9, and an adhesive dispensing frame 10. The adhesive storage cylinder 9 can store and discharge the adhesive, and the adhesive dispensing frame 10 can discharge the adhesive. In the prior art, the above components are mature equipment, and there are different names, which does not affect that they are mature products of the prior art. The specific structure and working principle will not be described in detail here.

[0024] The processing platform 2 is provided with a placement groove 3 for placing foam. The placement groove 3 is provided with a lifting plate 5 connected to a cylinder 4. The processing platform 2 is provided with a collection groove 6. The processing platform 2 is provided with a horizontal screw 20 through two fixed plates 11 and a drive motor 12. A scraper 13 is threaded on the horizontal screw 20. A vertical screw 15 is provided on the scraper 13 through a rotating port 14. The processing platform 2 is provided with a transmission groove 16. A rack 18 is provided in the transmission groove 16. The end of the vertical screw 15 extends into the transmission groove 16 and is connected to the rack 18 through a transmission mechanism. A lower pressure frame 19 is threaded on the vertical screw 15.

[0025] The transmission mechanism includes a gear 17 installed at the end of the vertical screw 15, which meshes with a rack 18. The gear 17 and rack 18 together enable the vertical screw 15 to rotate when the scraper plate 13 moves, and the vertical screw 15 has threads only on the outer wall of the part inside the rotation port 14.

[0026] The base 1 is provided with a ramp 8, and the collection tank 6 is provided with a mating opening 7 corresponding to the ramp 8. The ramp 8 is designed to facilitate the smooth passage of glue scraped to this location through the mating opening 7 into the collection tank 6 for collection.

[0027] Limiting rods 21 are provided between the two fixed plates 11 and inside the rotating opening 14. The two limiting rods 21 slide through the scraper plate 13 and the lower pressure frame 19 respectively. The aforementioned limiting rods 21 respectively limit the scraper plate 13 and the lower pressure frame 19, preventing them from rotating together with the horizontal screw 20 and the vertical screw 15.

[0028] Multiple vertical rods are installed on the base 1, and the ends of the vertical rods are fixedly connected to the bottom wall of the processing platform 2. The vertical rods are not labeled in the figure. The vertical rods are used to fix the base 1 and the processing platform 2 together.

[0029] A cylinder 4 is mounted on the base 1. The telescopic end of the cylinder 4 slides through the bottom of the processing platform 2. A lifting plate 5, connected to the telescopic end of the cylinder 4, is located in the placement groove 3. The foam placed in the placement groove 3 rests on the lifting plate 5, and its height is lower than the upper surface of the processing platform 2 for easy gluing. After gluing, the foam is flush with the surface of the processing platform 2. After gluing, the cylinder 4 can lift the foam through the lifting plate 5 to detach it from the placement groove 3 for easy removal.

[0030] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods of each component adopt mature methods in the prior art, and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] In use, the foam is placed on the lifting plate 5, and the adhesive in the storage cylinder 9 falls onto the surface of the foam through the dispensing frame 10, accumulating on the side closest to the drive motor 12. Then, the drive motor 12 is started to drive the horizontal screw 20 to rotate. When the horizontal screw 20 rotates, the scraper 13 moves and gradually approaches the collection tank 6. During this process, the scraper 13 can flatten the accumulated adhesive. As the scraper 13 moves, the higher pile of adhesive is slowly applied to the foam surface, and the pile height gradually decreases. The pressure frame 19 designed in this scheme moves with the scraper 13, and through the cooperation of the gear 17 and the rack 18, it slowly descends, changing with the adhesive as the height changes, ensuring the quality of adhesive application. Finally, the scraper 13 moves to the ramp 8, where excess adhesive can be scraped off and enter the collection tank 6. The pressure frame 19 is also at its lowest point, scraping off the adhesive on the surface of the scraper 13 and entering the collection tank 6.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
