Reciprocating compression molding system for non-woven fabrics

Abstract

The invention discloses a reciprocating compression molding system for non-woven fabrics. A cylinder is vertically fixed at the upper end of a bracket; an upper mold plate and a lower mold plate are horizontally arranged, and the upper mold plate is arranged above the lower mold plate; the lower end of the bracket is fixed on the lower mold plate; the lower end of a guide post is fixed on the upper side of the upper mold plate; the upper end of the guide post penetrates through the upper side of the bracket and is arranged together with the bracket in a sliding manner; the upper side of the upper mold plate is connected with the lower end of a piston rod of the cylinder by virtue of a movable connecting piece; the movable connecting piece can rotate up and down by a certain angle at any angle along a horizontal direction; guide rails are arranged along a transmission direction of the non-woven fabrics, and the lower mold plate is arranged on the guide rails in a sliding manner; and thebracket is connected with a traction mechanism and is driven by the traction mechanism to slide along the guide rails. Transmission of the non-woven fabrics does not need to be stopped, and dynamic press fit can be directly performed. Meanwhile, the upper mold plate is pressed by adopting the movable connecting piece, and due to self-adaptive angle adjustment, uniform pressing strength is ensured.

Description

Technical field [0001] The invention relates to a molding system, in particular to a non-woven fabric reciprocating molding system. Background technique [0002] Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, lightweight, non-combustible, and easy to decompose , Non-toxic, non-irritating, rich in color, low price, recyclable and so on. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. [0003] Non-woven fabric is a kind of fabric that does not need to be spun and weaves, but only oriented or randomly arranged woven short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical m...

Problems solved by technology

Glue usually uses balm and hydrogel. After smearing balm and hydrogel on the non-woven fabric and compounding the film, the two need to be pressed into shape. The traditional plate pressing method directly stops the non-woven fabric. Transmission, and then drive the press plate for pressing, which is not only inefficient but also easy to cause uneven pressing and affect the quality of the final product
