Detailed Embodiments

[0019] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments, in which the illustrative embodiments and descriptions are only used to explain the present utility model, but not to limit the present utility model. Embodiment

[0020] Please refer to Figure 1 and Figure 4, this embodiment provides a squeegee mechanism for a coater, which includes a distribution roller 3. Bearings 1 are provided at both ends of the distribution roller 3, and the bearings 1 are connected to the distribution roller 3 through bearing bodies 2. The squeegee mechanism further includes two oppositely arranged brackets 8 and a rubber scraping plate 6 disposed between the two brackets 8. The front side of the rubber scraping plate 6 abuts against the roller surface of the distribution roller 3, and the contact position between the rubber scraping plate 6 and the roller surface of the distribution roller 3 is located above and behind the rotation axis of the distribution roller 3. The rubber scraping plate 6 is floatingly connected to the bracket 8.

[0021] Due to the floatingly arranged rubber scraping plate 6, the rubber scraping plate 6 always fits against the roller surface of the distribution roller 3, scraping the glue liquid on the surface of the distribution roller 3, enabling the distribution roller 3 to maintain a relatively high rotational speed, increasing the yarn gluing speed, and improving production efficiency.

[0022] Please refer to Figure 1 , to ensure the scraping effect of the rubber scraping plate 6, the rubber scraping plate 6 usually needs to be trimmed. In this embodiment, an installation groove 7 extending backward and downward is provided at the top of the bracket 8. Rotating shafts 60 are provided at both ends of the rubber scraping plate 6, and the rotating shafts 60 extend into the installation groove 7, enabling the rubber scraping plate 6 to be quickly disassembled and assembled, improving the trimming efficiency.

[0023] Please refer to Figure 1 , a counterweight frame 4 is provided on the rubber scraping plate 6. The counterweight frame 4 includes a vertically extending vertical portion 42, a horizontally extending horizontal portion 41, a mounting portion 40 provided at the front end of the horizontal portion 41, and a counterweight 5 provided on the mounting portion 40. The tail end of the horizontal portion 41 is connected to the top of the vertical portion 42. The counterweight 5 on the counterweight frame 4 enables the rubber scraping plate 6 to always fit against the roller surface of the distribution roller 3.

[0024] Please refer to Figure 1 , the mounting portion 40 is a rod extending upward, the counterweight 5 is in the shape of a disc with a through hole in the middle, the counterweight 5 has multiple weights, and the rod is inserted into the middle through hole of the counterweight 5. By using counterweights 5 of different weights, the pressure between the rubber scraping plate 6 and the distribution roller 3 can be changed to suit distribution rollers 3 with different working speeds. The rod facilitates the replacement of the counterweight 5.

[0025] Please refer to Figure 2 , to facilitate the installation of the bracket 8, the bracket 8 is provided with a forward-extending mounting portion 9. The bottom of the mounting portion 9 abuts against the top of the base of the bearing 1, and the rear side of the base of the bearing 1 abuts against the front side of the bracket 8 to improve the stability of the bracket 8. The mounting portion 9 and the bearing 1 are connected to the equipment through the same bolt, which is convenient for disassembly and assembly.

[0026] Please refer to Figure 3, the rubber scraping plate 6 includes a rubber scraping beam 61 and a rubber scraping strip 62 detachably connected to the front side of the rubber scraping beam 61. The rubber scraping strip 62 extends along the length direction of the rubber scraping beam 61, and can be locally replaced and trimmed, reducing the maintenance cost.

[0027] Please refer to Figure 3 , an installation groove 7 is provided on the front side of the rubber scraping beam 61, and one side of the rubber scraping strip 62 is inserted into the installation groove 7, which is convenient for quickly replacing the rubber scraping strip 62 and improving the replacement efficiency.

[0028] Please refer to Figure 3 , the side of the rubber scraping strip 62 in contact with the uniform distribution roller 3 is an arc surface, so that the front side of the rubber scraping strip 62 is always in contact with the roller surface of the uniform distribution roller 3. An arc-shaped guide edge 63 is provided on the front side of the bottom of the rubber scraping strip 62 to guide the scraped glue into the glue tank, which is more environmentally friendly; in order to further prevent the glue from flowing onto the rubber scraping beam 61, under normal working conditions, the front side of the rubber scraping strip 62 is lower than the rear side of the rubber scraping strip 62.

[0029] During operation, the uniform distribution roller 3 rotates, and the yarn after being dipped in glue passes through the upper roller surface of the uniform distribution roller 3. The uniform distribution roller 3 makes a corresponding rotation. The rolling direction of the upper roller surface of the uniform distribution roller 3 is opposite to the running direction of the yarn. The rubber scraping strip 62 is attached to the roller surface of the uniform distribution roller 3, and the glue is transferred to the glue pool through the uniform distribution roller 3. The rubber scraping plate 6 scrapes off the residual glue on the uniform distribution roller 3.

[0030] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
