An extrusion device with adjustable longitudinal uniformity of pre-coating film and its application method

Abstract

The invention discloses an extrusion device for adjusting the longitudinal uniformity of a pre-coating film and a method for using the same, and relates to the technical field of adjusting the extrusion device for pre-coating films. The output adjustment is extremely inconvenient and cannot be precisely controlled, which affects product quality. The upper end of the support base is equipped with a main body bracket, the lower end of the main body bracket is equipped with a discharge bracket, the lower end of the discharge bracket is equipped with a limit guide rail, and an adjustment bracket is installed on the outside of the limit guide rail. There are two brackets, the two adjustment brackets are connected by a slot, the inside of the adjustment bracket is equipped with a first adjustment screw rod, the inside of the adjustment bracket is equipped with an adjustment flap, and the adjustment flap It is rotatably connected with the adjustment bracket through a connecting shaft, and a second adjustment screw rod is installed inside the lower end of the adjustment bracket, and a push plate is installed at one end of the second adjustment screw rod.

Description

technical field [0001] The invention relates to the technical field of adjusting pre-coating film extrusion devices, in particular to an extrusion device for adjusting the longitudinal uniformity of pre-coating films and its use method. Background technique [0002] Pre-coated film refers to the process of gluing and rewinding plastic film in advance, and then compounding it with paper prints. First, the pre-coating film processing factory applies the glue solution on the film according to the use specifications and format, and then rewinds it for the manufacturer to choose, and then compound it with the printed matter. The coated printed matter has a smoother and brighter surface due to the addition of a thin and transparent plastic film on the surface, thereby improving the gloss and fastness of the printed matter. Antifouling, abrasion resistance, folding resistance, chemical corrosion resistance, etc., play a great role in the long-term protection of printed matter. ...
