[0007] Step 2: Install a roller 5 at the bottom of the handheld base 1 to achieve a moving function when scraping glue;

[0008] Step 3: A cavity is opened inside the handheld base 1 for storing the sealant, and the sealant in the cavity is squeezed with the movable glue squeezer 6 to make the sealant flow out;

[0009] Step 4: Apply the sealant by scraping with a scraper.

[0010] Step 5: Determine the structural form, connection form, number of components, and size parameter information of steps 1 to 4 through optimization design or calculation analysis, and finally complete the design of the automatic coating structure of the scraper-type sealant.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention includes an automatic coating structure of a scraper-type sealant, which is used to improve the coating quality and coating efficiency of the scraper-type sealant. The automatic coating structure of the scraper-type sealant includes a handheld base 1, a height adjuster 2, a scraper 3, a fixing bolt 4, a roller 5, a glue squeezer 6, a limit shaft 7, and a transmission mechanism 8. The handheld base 1 has a cavity inside, a glue injection hole on the upper part, a cylindrical hole on the front part, a roller 5 installed at the bottom of the front end, and a transmission mechanism 8 installed at the bottom of the rear end. The height adjuster 2 is installed in the cylindrical hole of the handheld base 1, the scraper 3 is connected to the height adjuster 2 by the fixing bolt 4, the glue squeezer 6 is installed between the transmission mechanism 8 and the handheld base 1, and is limited by the limit shaft 7. When rolling, the transmission mechanism 8 can drive the glue squeezer 6 to move to achieve the glue squeezing function.

[0022] The following examples illustrate the specific steps of using the embodiment of the present invention:

[0023] Step 1: Loosen the fixing bolt 4, select a suitable scraper 3 according to the sealant coating width, shape, thickness and other requirements, and adjust the height adjuster 2 at the same time. After the adjustment is completed, install the fixing bolt 4;
