[0018] Explanation of the accompanying drawings: mounting seat 1, rocker arm assembly 2, adaptive rocker arm 21, reset mechanism 22, reset torsion spring 221, limiting mechanism 23, limiting block 231, limiting adjustment bolt 232, scraper module 3, mounting block 31, adjusting cavity 311, adjusting column 32, internal threaded portion 321, anti-rotation strip groove 322, scraper 33, adjusting bolt 34, anti-rotation member 35, tightening elastic member 36, blowing block 37, air inlet hole 371, first air blowing hole 372, second air blowing hole 373, limiting groove 374. Specific implementation method:

[0019] The utility model will be further described below in conjunction with the accompanying drawings. Figure 1-4As shown, the utility model includes a mounting seat 1, a rocker assembly 2 arranged on the mounting seat 1, and a scraper module 3, wherein the rocker assembly 2 includes an adaptive rocker 21 hinged on the mounting seat 1, a reset mechanism 22 for providing a rebound force to the adaptive rocker 21, and a limit mechanism 23 for resisting the rebounding adaptive rocker 21, and the scraper module 3 is arranged on the adaptive rocker 21, and the scraper module 3 includes a scraper 33; compared with the existing rigid scraper 33 device, no matter whether the height of the plate to be scraped at the position becomes larger or smaller, the blade position of the scraper 33 will not change; when the utility model is used to scrape the residual glue on the surface of the plate, each plate to be scraped with glue is sequentially transmitted through the utility model, and as the plate moves, the scraper 33 in the scraper module 3 of the utility model scrapes the residual glue on the surface of the plate, and when the plate is at the position to be scraped When the height of the plate is higher than the height of the blade position of the scraper 33, the plate pushes the scraper 33 obliquely upward, the adaptive swing rod 21 rotates obliquely upward, and the blade position of the scraper 33 adaptively increases upward. When the height of the plate at the position to be scraped returns to a lower level, the plate stops pushing the scraper 33 obliquely upward, and the adaptive swing rod 21 rotates obliquely downward and resets under the action of the rebound force of the reset mechanism 22, and the blade position of the scraper 33 adaptively decreases downward, thereby realizing the up and down adaptive adjustment of the scraper 33. The scraper 33 of the utility model can automatically perform up and down adaptive adjustment, and even when scraping glue on plates with different heights on both sides, the blade of the scraper 33 can always fit the surface of the plate and only scrape off the residual glue on the surface of the plate without scraping the plate itself, so that the residual glue on the surface of the plate can be well removed while ensuring that the plate will not be damaged by scraping.

[0020] The reset mechanism 22 includes a reset torsion spring 221 arranged on the mounting seat 1, one end of the reset torsion spring 221 is connected to the mounting seat 1, and the other end of the reset torsion spring 221 is connected to the adaptive rocker 21. The reset torsion spring 221 generates a torque opposite to the sheet pushing the adaptive rocker 21, so that the blade of the scraper 33 can always press against the surface of the sheet, thereby ensuring that only the residual glue on the surface of the sheet is scraped away without scraping the sheet itself.

[0021] The reset torsion spring 221 is embedded in the adaptive rocker arm 21. The reset torsion spring 221 of the utility model adopts a hidden design. Not only can the reset torsion spring 221 not be seen from the outside of the mechanism, making the overall structure more concise and beautiful, but it can also prevent the reset torsion spring 221 from being stuck due to foreign objects falling into it, and can better ensure that the reset torsion spring 221 can stably provide the adaptive rocker arm 21 with a rebound force.

[0022] The limiting mechanism 23 includes a limiting block 231 arranged on the mounting seat 1 and a limiting adjustment bolt 232 threadedly connected to the limiting block 231, one end of the limiting adjustment bolt 232 protrudes from the limiting block 231 and abuts against the adaptive rocker arm 21; by adjusting the limiting adjustment bolt 232 by forward or reverse rotation, the length of the limiting adjustment bolt 232 protruding from the limiting block 231 can be adjusted, that is, the position against which the adaptive rocker arm 21 abuts can be adjusted, so that the limiting position of the adaptive rocker arm 21 can be adjusted according to specific usage conditions, that is, the limiting position of the shovel blade 33 can be adjusted according to specific usage conditions, which is more practical.

[0023] The scraper module 3 includes a mounting block 31, an adjusting column 32 slidably connected to the mounting block 31 in the vertical direction, a scraper 33 arranged on the adjusting column 32, an adjusting bolt 34 arranged on the top of the mounting block 31, and a stopper 35 arranged on the front end of the mounting block 31. The top of the adjusting column 32 is formed with an internal threaded portion 321 that matches the adjusting bolt 34. The adjusting bolt 34 is threadedly connected to the internal threaded portion 321 of the adjusting column 32. The front end of the adjusting column 32 is formed with a stopper strip groove 322. The rear end of the stopper 35 protrudes into the stopper strip groove 322 and The two side walls of the anti-rotation strip groove 322 abut against each other. When the height position of the scraper 33 is adjusted, the utility model only needs to screw the adjusting bolt 34 in the forward or reverse direction. With the cooperation of the anti-rotation part 35 and the anti-rotation strip groove 322 of the adjusting column 32, the rotation of the adjusting bolt 34 will drive the adjusting column 32 to slide upward or downward, thereby adjusting the height position of the scraper 33. The utility model is not only easier to adjust the height position of the scraper 33, but also can adjust the height position of the scraper 33 more precisely, and can be better suitable for the scraper 33 device.

[0024] The mounting block 31 is formed with an adjustment cavity 311, and the adjustment column 32 is slidably connected in the adjustment cavity 311 of the mounting block 31 in the vertical direction. A clamping elastic member 36 is sandwiched between the top of the adjustment column 32 and the top wall of the adjustment cavity 311. The clamping elastic member 36 generates a clamping force that always presses the adjustment column 32 downward, thereby eliminating the thread gap and does not generate a gap displacement error, thereby further improving the adjustment accuracy of the height position of the adjustment column 32, that is, the adjustment accuracy of the height position of the scraper 33 can be further improved.

[0025] The elastic member 36 is a spring or a plurality of elastic gaskets stacked in the vertical direction. The elastic member 36 in this embodiment is a plurality of elastic gaskets stacked in the vertical direction. Of course, in other embodiments, the elastic member 36 can also be a spring or other elastic components.

[0026] The scraper module 3 also includes a blowing block 37, the blowing block 37 is connected to the adaptive swing rod 21, the mounting block 31 is connected to the blowing block 37, the blowing block 37 is formed with an air inlet hole 371, a first air blowing hole 372 connected to the air inlet hole 371, and a second air blowing hole 373 connected to the air inlet hole 371. The first air blowing hole 372 is located at the bottom of the front end of the blowing block 37 and is arranged close to the scraper 33. The second air blowing hole 373 is located at the bottom of the blowing block 37 close to the side where the sheet material flows into. The air inlet 371 is connected to the air source, and air is blown onto the glue scraped off by the scraper 33 through the first blowing hole 372 to prevent the scraped glue from being retained on the surface of the scraper 33 and affecting the scraper 33, so that the scraper 33 can scrape the glue better. The surface of the plate where the glue is to be scraped is blown onto through the second blowing hole 373 to prevent dust and other foreign matter from being present on the surface of the plate where the glue is to be scraped and affecting the scraper 33, thereby better ensuring the scraping effect of the scraper 33.

[0027] The blowing block 37 is formed with a limiting groove 374, and the mounting block 31 is arranged in the limiting groove 374. The front wall of the limiting groove 374 abuts against the rear end of the mounting block 31, and the two side walls of the limiting groove 374 abut against the two sides of the mounting block 31 respectively; the mounting block 31 is limited by the limiting groove 374, and the mounting block 31 is not prone to position displacement, which can improve the stability of the mounting block 31, thereby improving the stability of the scraper 33.

[0028] Working principle:

[0029] The plates to be scraped with glue are sequentially conveyed through the utility model. As the plates move, the scraper 33 in the scraper module 3 of the utility model scrapes away the residual glue on the surface of the plates. When the height of the plate to be scraped is higher than the height of the blade position of the scraper 33, the plate pushes the scraper 33 obliquely upward, the adaptive swing rod 21 rotates obliquely upward, and the blade position of the scraper 33 adaptively increases upward. When the height of the plate to be scraped is restored to a lower level, the plate stops pushing the scraper 33 obliquely upward, and the adaptive swing rod 21 rotates obliquely downward under the action of the rebound force of the reset mechanism 22 to reset, and the blade position of the scraper 33 adaptively decreases downward, thereby realizing the up and down adaptive adjustment of the scraper 33. The scraper 33 of the utility model can automatically perform up and down adaptive adjustment. Even when scraping glue on plates with different heights on both sides, the blade of the scraper 33 can always fit the surface of the plate and only scrape away the residual glue on the surface of the plate without scraping the plate itself. It can well remove the residual glue on the surface of the plate while ensuring that the plate is not damaged by scraping.

[0030] Of course, the above is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
