Description

Technical Field

[0001] This invention relates to the field of glue reuse technology, and more specifically to a glue recycling device and a glue spraying system. Background Technology

[0002] With the rapid development of 3C products, lamination technology is increasingly being used in them. This lamination process inevitably involves the use of adhesive. Typically, when too much adhesive is used, it flows along the product surface to the surrounding area of ​​the lamination platform. To prevent damage to surrounding machines and to avoid adhesive residue affecting the next product to be laminated, lamination personnel collect the excess adhesive for disposal. This process usually involves spraying adhesive onto the product using a spray gun, laminating it, and then using a blade to carefully scrape off the excess adhesive for disposal. Finally, the platform surface is wiped clean with a lint-free cloth. This process not only wastes a large amount of adhesive, increasing manufacturing costs, but also adds time to wiping the platform, significantly reducing lamination efficiency. Furthermore, allowing the adhesive to flow freely can damage surrounding machines.

[0003] Therefore, it is necessary to provide an adhesive recycling device to realize the recycling and reuse of adhesive and to avoid damage to the machine by adhesive. Summary of the Invention

[0029] Machines 200, fixtures 201, products 300

[0030] The adhesive recycling device 100 includes a first recycling mechanism 110, a base 10, a motor 20, a rotating mechanism 30, a screw rod 31, a screw blade 33, a receiving part 40, a feed inlet 41, a lug part 43, a first opening part 45, a bent tube part 46, and a straight tube part 47.

[0031] The second recycling mechanism 120, recycling bin 50, first glue inlet 51, glue outlet 52, second glue inlet 53, inlet 54, drive unit 60, stirring mechanism 70, and stand 80. Detailed Implementation

[0032] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0033] Figures 1-2 A schematic diagram of a glue spraying system is provided. This system includes a circular machine platform 200, on which several fixtures 201 are arranged in a ring. A product 300 is positioned on one of the fixtures 201. A spray gun (not shown) sprays glue onto the product 300. A glue recovery device 100 is located opposite the spray gun. For details, please refer to [reference needed]. Figures 3-4The glue recycling device 100 includes a first recycling mechanism 110 and a second recycling mechanism 120 that are connected to each other. The first recycling mechanism 110 includes a base 10, a motor 20, a rotating mechanism 30, and a receiving part 40. The motor 20 is mounted on the base 10. The output end of the motor 20 is connected to the rotating mechanism 30. The receiving part 40 is connected to the base 10 and has an inlet 41 and an outlet. The lower end of the inlet 41 extends outward from the upper end to form a lug 43. The lug 43 is located below the product. The rotating mechanism 30 is located inside the receiving part 40. The motor 20 drives the rotating mechanism 30 to rotate to agitate the glue entering the receiving part 40. The glue processed by the rotating mechanism 30 flows out from the outlet. The second recycling mechanism 120 has a cavity and is connected to the outlet.

[0034] In the above technical solution, using the glue recycling device 100, the lug 43 of the receiving part 40 is located below the product. When the product is sprayed with glue using a spray gun, the sprayed glue splashes directly onto the feed port 41. The glue overflowing from the product also flows into the feed port 41 through the lug 43. After flowing into the receiving part 40 from the feed port 41, the glue is very uniform after being agitated and cut by the rotating mechanism 30, and flows out from the discharge port to the second recycling mechanism 120, thereby realizing the recycling and reuse of glue, saving manufacturing costs, and avoiding damage to the machine 200 caused by glue.

[0035] Please continue to refer to this. Figures 3-4 An air blowing plate (not shown) is provided at the upper end of the feed inlet 41. During glue spraying, the air blown out by the air blowing plate allows the glue overflowing from the product to quickly flow into the lug 43. It should be understood that the opening of the feed inlet 41 can be configured to fit the production line to maximize the product's position within the opening without affecting glue spraying and product operation. In some embodiments, the lug 43 is inclined downwards into the feed inlet 41, facilitating the rapid flow of glue from the lug 43 into the feed inlet 41. Further, the receiving part 40 includes a first opening 45, a bent tube 46, and a straight tube 47. The bent tube 46 is located between the first opening 45 and the straight tube 47. The first opening 45 is provided with the lug 43, and the straight tube 47 is connected to the base 10. In other words, a channel for glue flow is formed through the first opening 45, the bent section 46, and the straight section 47. The rotating mechanism 30 is located in the straight section 47. Glue flows from the inlet 41 of the first opening 45 through the bent channel into the straight section 47 for agitation and cutting, and then flows out from the outlet of the straight section 47. In a preferred embodiment, the lug 43 is inclined towards the channel to facilitate rapid flow of glue from the lug 43 into the outlet. In a preferred embodiment, the rotating mechanism 30 includes a spiral rod 31 and spiral blades 33 spirally disposed on the spiral rod 31.

[0036] Please refer to Figures 5-6The second recycling mechanism 120 includes a recycling bin 50, a drive unit 60, and a stirring mechanism 70. The stirring mechanism 70 is connected to the drive shaft of the drive unit 60. The recycling bin 50 has a cavity and a first glue inlet 51 that connects to the discharge port. The stirring mechanism 70 is located inside the recycling bin 50. The drive unit 60 drives the stirring mechanism 70 to rotate and stir the glue in the cavity. The drive unit 60 can be, but is not limited to, a motor. That is, the glue from the discharge port flows into the recycling bin 50 through the first glue inlet 51, and the drive unit 60 drives the stirring mechanism 70 to rotate and stir the glue in the recycling bin 50 evenly for later use. The stirring mechanism 70 can be a cross-shaped structure, a three-pronged structure, a multi-pronged structure, etc. Further, the bottom of the recycling bin 50 is also provided with a glue outlet 52. In one embodiment, the glue outlet 52 is connected to a spray gun. Preferably, the glue is pumped into a temporary storage tank through a pump connected to the glue outlet 52, and then the spray gun is connected to the temporary storage tank. Furthermore, the side wall of the recycling bin 50 is also provided with a second glue inlet 53 for adding new glue. When the glue level in the recycling bin 50 is low, new glue can be added through the second glue inlet 53 to replenish it. In a preferred embodiment, the side wall of the recycling bin 50 is also provided with an inlet 54 for adding hardener. Hardener is added into the recycling bin 50 through the inlet 54 as needed. In some embodiments, the second recycling mechanism 120 also includes several legs 80 supporting the recycling bin 50, which provide stable support for the recycling bin 50.

[0037] The following is combined Figure 1-6 The working principle of the adhesive spraying system of the present invention is explained in detail.

[0038] The spray gun sprays adhesive onto the product, and excess adhesive splashes into the feed inlet 41. Adhesive overflowing from the product also flows into the feed inlet 41 through the lug 43. The motor 20 drives the spiral rod 31 to move, so that the spiral blade 33 agitates and cuts the adhesive, achieving uniform adhesive. The adhesive enters the recycling tank 50 through the discharge port, and is then agitated by the stirring mechanism 70 in the recycling tank 50 before flowing out through the adhesive outlet 52 for use by the spray gun. This achieves the recycling and reuse of adhesive, saving manufacturing costs.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
