Double roller glue application device of solvent-free compound machine

Abstract

The invention discloses a double roller glue application device of a solvent-free compound machine. The double roller glue application device includes a worktable, a base material, fourth connecting rods, a third supporting plate, first rotating rods and glue scraping plates; a glue groove is formed in the upper end surface of the worktable, and two sets of first supporting plates are arranged onthe worktable; a heating tube is arranged at the groove bottom of the glue groove; third connecting rods are arranged at the bottoms of the two sets of first supporting plates; glue application rollers sleeve the third connecting rods; the glue scraping plates are in contact with the glue application rollers; the fourth connecting rods are located above the third connecting rods, edge pressing rollers sleeve the fourth connecting rods; connecting plates are arranged on the two sides of the fourth connecting rods; second supporting plates are arranged at the tops of the two sets of connecting plates; the bottoms of the first rotating rods penetrate through first through holes to extend into the upper parts of the second supporting plates, first limiting rings and second limiting rings sleeve the first rotating rods, and screws are arranged at the bottoms of the first rotating rods; and the screws are matched with thread holes. The glue application work of the base materials with different thicknesses can be satisfied; and meanwhile, the arrangement of guiding rollers can play a tensioning role and prevent the material from loosening during the glue application process.

Description

technical field [0001] The invention relates to the technical field of double-roller gluing devices, in particular to a double-roller gluing device for a solvent-free composite machine. Background technique [0002] Solvent-free lamination machine is a method of laminating two or more substrates together with a solvent-free adhesive, also known as reactive lamination. Solvent lamination machine is an environmentally friendly and economical flexible packaging composite material production process. , has obvious advantages in economy, safety and environmental protection. It is to coat the rolled material with a layer of glue, paint or ink with a specific function, and then roll it after drying. When the existing equipment applies glue, the material is prone to loosening during operation, resulting in uneven glue application and affecting the quality of the material. At the same time, most of the existing glue application devices are single-roller glue application, and the stab...

Problems solved by technology

When the existing equipment is gluing, the material is prone to loosening during operation, resulting in uneven gluing and affecting the quality of the material. At the same time, most of the existing gluing devices are single-roller gluing, and the stability of gluing quality is difficult to guarantee.
