Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive compounding machines, in particular to a scraper structure assembly of a hot melt adhesive compounding machine. Background Art

[0002] The laminating machine is to bond two or more layers of materials together with adhesive. Such as film and aluminum foil, film, paper, non-woven fabrics, etc. are often used. It can also be compounded with film, sponge, cloth, etc. When the hot melt adhesive laminating machine is in use, a hot melt adhesive laminating machine scraper structure assembly is required to evenly spread the glue on the glue roller.

[0003] According to the description of a scraper device for a compound machine disclosed in the patent website (authorization announcement number: CN 216880028U), "The utility model discloses a scraper device for a compound machine, which relates to the technical field of compound machines, in order to solve the problem that the scraper used in the existing compound machine needs to be pulled out for cleaning after being used for a period of time, and this method is relatively cumbersome to operate. Connecting rod bodies are provided at both ends of the scraper connecting body, and there are two connecting rod bodies. An external water pipe is provided on one side of the two connecting rod bodies. The two connecting rod bodies are rotatably connected to the scraper connecting body through a second electric adjustment shaft, and there are two second electric adjustment shafts. A delivery water pipe is provided between the two connecting rod bodies, and the two ends of the delivery water pipe are rotatably connected to the two connecting rod bodies through a third electric adjustment shaft, and there are two third electric adjustment shafts. A spray high-pressure water nozzle is provided on the outer wall of the delivery water pipe, and there are a plurality of spray high-pressure water nozzles, and the plurality of spray high-pressure water nozzles are fixedly connected to the delivery water pipe."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model cleans the scraper by spraying a high-pressure water nozzle, which enhances the convenience of operation when cleaning the scraper, avoids the scraper used in the existing compound machine having to be pulled out for cleaning after being used for a period of time, and installs the scraper by snap-on friction blocks and anti-collision rubber blocks. However, in actual use, when the scraper is installed in the scraper mounting plate and the length is too long, the scraper will leak out too short, which will make the distance between the scraper and the glue roller far, and the scraper mounting plate is adjusted by rotating the scraper mounting plate, so that the scraping position is misaligned, which is easy to cause glue leakage. When the scraper is installed in the scraper mounting plate and the length is too short, the scraper is only installed by snap-on friction blocks and anti-collision rubber blocks, and the installation is unstable and easy to fall off. Secondly, the scraper is installed from one side of the scraper mounting plate, and it is easy to fall off from one side. The snap-on friction blocks and anti-collision rubber blocks also make installation difficult. Therefore, it is necessary to improve a hot melt adhesive compound machine scraper structure assembly to solve the above problems. Utility Model Content
