Description

Technical Field

[0001] The utility model relates to the technical field of gluing, in particular to a uniform gluing nozzle structure for papermaking. Background Art

[0002] Sizing is an important process in papermaking production. Its purpose is to effectively slow down the yellowing of paper, improve paper quality, and improve adaptability. With the continuous improvement of regional living standards, people's demand for safe and high-quality paper products continues to increase. In order to improve paper quality, companies will evenly spray glue on the surface of the paper to form an extremely thin waterproof layer, which greatly improves the water absorption, strength and tightness of the paper. Sizing on the surface of paper can not only meet the performance requirements of various special occasions, but also improve the physical strength, abrasion resistance, durability, feel and smoothness of the paper, and overcome defects such as fuzzing and powdering of the paper surface. However, the sizing nozzle used can only spray out one form when applying glue, resulting in too single selectivity when sizing paper surfaces of different areas, which easily leads to waste of glue and lack of practicality.

A glue spray hose 3 passes through one end of the frame 2 near the upper end, and the other end of the glue spray hose 3 is rotatably connected to a connecting pipe 301. A second valve 401 is provided on the upper end of the glue spray hose 3 on the outer surface of the connecting pipe 301, and a first valve 4 is provided on the lower end of the glue spray hose 3 on the outer surface of the connecting pipe 301. A second nozzle 303 is fixedly mounted on the upper end of the connecting pipe 301, and a first nozzle 302 is fixedly mounted on the lower end of the connecting pipe 301. An adjustment structure 5 is provided on the other end of the frame 2.

[0019] The adjusting structure 5 includes a bearing 501, a rotating shaft 502, a slot 503, a latch 504, a limit block 505, a rectangular block 506, a rectangular slot 507, a return spring 508, an L-shaped fixing frame 509, a circular guide rod 510, a circular sliding hole 511, and a fixing block 512; the other end surface of the inner side of the frame 2 is fixedly mounted with a bearing 501 near the upper end, the rotating shaft 502 is movably mounted on the inner surface of the bearing 501, and the upper and lower ports of the other end of the connecting pipe 301 are fixedly mounted with the rotating shaft 502; the upper and lower surfaces of the rotating shaft 502 are both provided with slots 503, and the slots 503 are provided with a latch 504, and the upper surface of the other end of the frame 2 is fixedly mounted with an L-shaped fixing frame 509; the other end of the L-shaped fixing frame 509 is fixedly mounted with a rectangular block 506, and a rectangular slot 507 is provided on the rectangular block 506. Circular sliding holes 511 are provided in the middle of the upper and lower surfaces; a circular guide rod 510 is slidably installed in the circular sliding hole 511, a bayonet 504 is fixedly installed at the lower end of the circular guide rod 510, a fixed block 512 is fixedly installed at the upper end of the circular guide rod 510, a limit block 505 is fixedly installed on the outer surface of the circular guide rod 510, and a return spring 508 is sleeved on the upper end of the limit block 505 on the outer surface of the circular guide rod 510.
