[0002] In carpet production, adhesive coating is a crucial step, directly impacting the carpet's performance and lifespan. Currently, carpet adhesive coating scraper mechanisms on the market have several issues. Traditional scraper mechanisms typically have a fixed structure, making it difficult to flexibly adjust to different carpet materials, adhesive properties, and coating thickness requirements. This results in uneven coating thickness, affecting the adhesion between the carpet and the floor, as well as the overall flatness of the carpet. Furthermore, some scraper mechanisms lack adequate designs for recycling excess adhesive, leading to adhesive waste and increased production costs. Therefore, we propose a new carpet adhesive uniform coating scraper mechanism. Utility Model Content

The setting of the integrated central control unit 8 facilitates the operator to perform integrated operation of this device and simplifies the operation process.

[0022] In this embodiment, when the carpet is initially coated with adhesive by the adhesive applicator, if it is necessary to adjust the thickness of the adhesive coating, the distance between the adjustment plate 3 and the carpet can be detected by the position sensor 7, thereby determining the distance between the scraper 5 and the carpet. Then, the cylinder 2 is powered on by the integrated central control unit 8, causing the cylinder 2 to drive the adjustment plate 3 to move up and down. At this time, the guide rod 12 limits and guides the movement of the adjustment plate 3. The adjustment plate 3 drives the scraper 5 to follow the up and down adjustment movement through the mounting block 4, thereby achieving the purpose of adjusting the distance between the scraper 5 and the carpet and realizing precise control of the coating thickness.

[0023] During the operation of the scraper 5, the scraped adhesive will accumulate on the back side of the scraper 5. The accumulated adhesive is guided by the guide hopper 63 with an open inclined surface. At the same time, the adhesive pump 61 starts to operate. The adhesive pump 61 extracts the adhesive guided by the guide hopper 63 through the adhesive extraction pipe 62 and the adhesive suction hopper 65. Then, it is transported to the adhesive storage tank 64 through the adhesive delivery pipe 66 for storage. At this time, the adhesive storage tank 64 is in a heated and constant temperature operation state, so that the adhesive collected in the adhesive storage tank 64 always maintains fluidity, which is conducive to subsequent recycling.

[0024] When the scraper 5 needs to be cleaned or replaced, the fixing bolt 13 on the mounting block 4 can be unscrewed, and the scraper 5 can be taken out from the groove on the mounting block 4 for the appropriate operation.
