Gluing machine for non-woven fabrics

Abstract

The invention discloses a gluing machine for non-woven fabrics, belonging to the technical field of gluing machinery for non-woven fabrics. The gluing machine comprises a rack, a beam, a glue feeding mechanism, a pair of glue blocking mechanisms, a pair of edge detecting mechanisms, a glue scraping mechanism and a glue squeezing mechanism, wherein a first beam support is fixed at the upper part of one end of the rack, and a second beam support is fixed at the upper part of the other end of the rack; the upper part of the rack is fixedly provided with a fabric guide platform, and one side of the rack is provided with a fabric guide roller, a fabric spreading roller and a transition roller; the beam is fixed on the first beam support and the second beam support, an upper guide rail is fixed on the upward side of the beam, and a lower guide rail is fixed on the downward side of the beam; the glue feeding mechanism is arranged on the beam; the pair of glue blocking mechanisms are matched with the upper and lower guide rails in a moving manner; the pair of edge detecting mechanisms are arranged on the pair of glue blocking mechanisms; the glue scraping mechanism is arranged on the rack; and the glue squeezing mechanism is arranged on the rack and corresponds to a space between the pair of glue blocking mechanisms and the glue squeezing mechanism. The gluing machine has the advantages of guaranteeing a uniform glue coating effect, preventing the two side edges of the non-woven fabrics from being separated from a glue feeding area of the glue feeding mechanism, avoiding the escape of glue, allowing the selvages of the non-woven fabrics to be stripped and spread, and preventing the non-woven fabrics from moving to two sides and the middle.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabric gluing machinery, in particular to a non-woven gluing machine . Background technique [0002] Non-woven fabrics are customarily called non-woven fabrics or non-woven fabrics. One or both sides of the non-woven fabric are coated with materials such as PU (polyurethane), PVC (polyvinyl chloride) or other similar materials, and then other interlining fabrics are combined with It can be compounded to form composite cloth or artificial leather or other similar cloths with a wide range of uses. It can be seen that gluing the surface of non-woven fabrics is the previous process of non-woven fabric compounding, and the device that gluing depends on is non-woven fabrics. Important equipment in the composite process. [0003] The technical information about the gluing machine used for non-woven fabrics can be seen in the published Chinese patent literature, typically such as the "single-sided...

Problems solved by technology

[0004] Not limited to the gluing machines listed above, although each has its own advantages, but as a complete gluing machine, how to feed the glue to the non-woven fabric relatively evenly, how to avoid the deviation of the non-woven fabric during the travel process, and how to control The thickness of the glue, avoiding waste of excess glue, and how to prevent the selvage of the non-woven fabric from curling and prevent both sides of the length of the non-woven fabric from swimming toward the middle are all indispensable technological requirements, but none of the above patents gives Provide technical inspiration to meet these process requirements
