A self-positioning multi-layer laminating machine

Abstract

It relates to the field of foam production and specifically discloses a self-positioning multi-layer laminating machine; it includes a frame, a motor, a negative pressure mechanism, a pair of conveying rollers and a positioning channel. The pair of conveying rollers includes an upper roller and a lower roller; positioning The channel includes a horizontal section and an inclined section; both the horizontal section and the inclined section include a first side and a second side; the inclined section is provided with an air inlet and a cleaning block; the negative pressure mechanism includes a blowing cylinder and a cylindrical cam, and the piston rod of the blowing cylinder It can slide along the contour curve of the side wall of the cylindrical cam. An air inlet one-way valve and an air outlet one-way valve are fixed on the side wall of the blowing cylinder. The air outlet one-way valve is connected with the air inlet; there is a negative pressure chamber in the upper roller or the lower roller. , there is a negative pressure hole on the side wall of the negative pressure chamber. The laminating machine of this solution can align paper and foam.

Description

technical field [0001] The invention relates to the field of foam production, in particular to a laminating machine. Background technique [0002] Foam is a material made of foamed plastic particles. It has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, convenient use, free bending, ultra-thin volume, and reliable performance. For convenient use, glue is usually coated on one side of the foam, and then the paper is pasted on the glue surface. It can play a fixed role, so there is no need to apply additional glue. [0003] In the actual production process, the forming of the foam, the application of glue, and the pasting of paper on the glue are completed in sequence. After the foam is formed, the long strip of foam is first rolled into rolls, and then transported to the gluing and sticker workshop. The foam is glued and pasted by a laminating machine. [0004] The laminating machine includes unwinding device, gluing device,...

Problems solved by technology

[0005] But the paper will be cut before it is aligned with the foam, and the shredded paper powder produced by cutting will adhere to the paper, and stick to the glue when the paper is in contact with the glue, which will reduce the viscosity of the glue. This kind of foam is a substandard product

Secondly, due to the softness of the paper, the paper is prone to wrinkles during the process of moving the paper, and the wrinkles will prevent the paper from fully covering the foam, exposing the glue to the air

In addition, the weight of the paper is small. During the moving process, the air flow will make the paper swing, so the paper is easy to move relative to the conveying roller in the conveying and pressing device, and finally cannot be completely aligned with the foam, so the paper cannot completely cover the glue. , this foam is substandard
