Winding no-bottom-wrinkle receiving mechanism

Abstract

The invention discloses a winding no-bottom-wrinkle receiving mechanism. The mechanism is characterized by comprising a rotatable mandrel, a mounting base driven to lift and move front and back through a first driving device, a pressing roller rotationally mounted on the mounting base, and a cutter driven to move in the width direction of a substrate through a second driving device, wherein the substrate passes between the pressing roller and the mandrel. The pressing roller moves up and down to bond the substrate on the mandrel; then, the substrate is cut off through movement of the cutter in the width direction of the substrate, so that the edge winding phenomenon of the substrate caused by a traditional automatic cutting mode can be greatly reduced; after the substrate is cut off, the first driving device drives the pressing roller to enable the pressing roller and the mandrel to extrude the substrate, and meanwhile, drives the pressing roller to act around the mandrel with an arc trajectory, so that the substrate can be preferably bonded on the roller surface of the mandrel to eliminate such defects as edge winding of the end surface of the substrate; and air between the mandrel and the substrate can be totally extruded out in the bonding process.

Description

technical field [0001] The invention relates to the field of winding of a coating machine, in particular to a winding bottomless wrinkle splicing mechanism. Background technique [0002] The existing film-type base material coating machine mainly has two mechanisms for rewinding and receiving materials: automatic material receiving or manual material receiving. The current automatic material receiving mechanism is easy to use, but due to the gap between the base material and the mandrel during the material receiving process Air is trapped between them, which often produces air bubbles; in addition, the end surface of the cut substrate is prone to curling, which leads to bottom wrinkles when changing rolls, that is, there is a long section of the substrate that has just started to be rolled. It cannot be used, and can only be used for waste disposal; in order to reduce waste, some customers prefer to choose manual splicing, relying on the operator to cut the base material and...

[0002] The existing film-type base material coating machine mainly has two mechanisms for rewinding and receiving materials: automatic material receiving or manual material receiving. The current automatic material receiving mechanism is easy to use, but due to the gap between the base material and the mandrel during the material receiving process Air is trapped between them, which often produces air bubbles; in addition, the end surface of the cut substrate is prone to curling, which leads to bottom wrinkles when changing rolls, that is, there is a long section of the substrate that has just started to be rolled. It cannot be used and can only be used for waste disposal; in order to reduce waste, some customers prefer to choose manual splicing, relying on the operator to cut the base material and wipe it by hand to eliminate the defects of bottom wrinkles; manual splicing mechanism, labor-intensive, It is also necessary to slow down the speed of the machine, which affects the production efficiency, and it is difficult to meet the needs of high-efficiency production; for this reason, the present invention provides a winding bottomless wrinkle automatic material receiving mechanism
