A kind of sandwich glue pressing device for production of sandwich plastic board

Abstract

The invention discloses a laminated glue pressing device for the production of interlayer plastic boards, which comprises: a base, a support bottom plate is arranged on the top, a rubber liner is arranged on the top surface of the support bottom plate, and the middle of the support bottom plate is uniform Parallel slots are arranged at intervals, and side limiting plates are symmetrically arranged on the left and right sides of the parallel slots; horizontal conveying rollers are fitted inside the parallel slots. In the present invention, the triangular connection sliders and the trapezoidal connection sliders arranged on both sides of the central pressing plate are fitted and slid against each other. The horizontal pressure roller connected in the middle will roll over the laminated plastic plate horizontally to remove the air bubbles. When the triangle connection slider moves to the lowest position, the trapezoid connection slider also moves horizontally to the outside. At this time, the plane below the center pressure plate The pressing plate is just able to carry out comprehensive pressing work on the laminated plastic sheet, and the processing efficiency is higher.

Description

technical field [0001] The invention relates to plastic board production equipment, in particular to a glue pressing device for sandwich plastic board production. Background technique [0002] In order to enhance the strength of the plastic board and prevent the plastic board from being completely broken after being damaged, the sandwich plastic board is generally made of two or more layers of plastic boards and corresponding glues alternately arranged and pressed together, and the production of sandwich plastic boards When laying an interlayer between the two layers of plastic boards, the interlayer is generally in a liquid state when it is laid. In order to ensure that the interlayer between the two layers of plastic boards is uniform, the plastic boards need to be pressed together, that is Apply pressure to the plastic plate, and the glue in it will flow and spread flat under the pressure, and bond with the plastic plate more tightly. The applicant found that air bubbles...

AI Technical Summary

Problems solved by technology

The applicant found that air bubbles are often generated between the laminate and the plastic board when it is laid, and the ordinary press-fitting device that applies force in the vertical direction cannot remove the air bubbles, which will result in lower strength and quality of the plastic board produced. Before vertical pressing, it is often necessary to use the roll structure to remove the air bubbles in between, and then press, so the air bubbles and pressing are often carried out separately and step by step, so the time interval between the two steps is longer, and the operation is more cumbersome. less productive
