New version roller for laser seamless double film press

Abstract

The invention discloses a novel plate roller of a laser seamless double film press. The novel plate roller comprises a plate roller I and a plate roller II for pressing a film on an area which is not pressed with the film, wherein the plate roller I comprises a first roller body and oil passing holes; the first roller body is solid; a first through shaft hole is formed in the axial direction of the first roller body; the first roller body can rotate around the first shaft hole circumferentially; the oil passing holes are uniformly distributed in the periphery of the first shaft hole and near one side of the outer wall of the first roller body and run through the first roller body in the longitudinal direction; the plate roller II comprises a second roller body, oil heating holes and mould pressing oil holes; the second roller body is solid; a second through shaft hole is formed in the axial direction of the second roller body; the second roller body can rotate around the second shaft hole circumferentially; the oil heating holes are uniformly distributed in the periphery of the second shaft hole, and run through the second roller body in the axial direction; the mould pressing oil holes are uniformly distributed in the periphery of the oil heating holes and run through the second roller body in the longitudinal direction.

Description

technical field [0001] The invention relates to a plate roll, in particular to a new type of plate roll for a laser seamless double film press used on a double film press. Background technique [0002] Ⅰ and Ⅱ version rollers are the key components of the laser seamless double film press machine. Perfectly emboss any laser holographic grating stripes pre-etched on the plate roller on 12-150μm thick BOPP, PVC, PET and other film materials to make a dazzling anodized aluminum radium grating film and elegant and mysterious rainbow hologram film. [0003] Among them, during the embossing process of the I version roller, the blank space left by the II version roller is embossed. Called seamless. [0004] The existing I and II version rollers need to be heated with high-temperature oil during work. The surface temperature of the plate roller must reach 200 degrees Celsius. The high temperature range will reach an angle of 320 degrees on the periphery of the plate roller garde...

AI Technical Summary

Problems solved by technology

Seriously affect product quality

[0007] Second, the service life of the version roller is short, and the average service life of a pair of brand-new Ⅰ and Ⅱ version rollers is two months

Great economic burden on the business

[0008] The related plate rolls recorded in existing patents, such as the plate rolls recorded in the Chinese patent application CN201020143399.6, a molded plate roll, although this type of plate roll reduces thermal deformation to a certain extent, but the center of this type of plate roll The rotating shaft is close to the two cavities, and the two cavities are separated by a partition, so the sealing process of this type of plate roll is complicated, and the liquid inside the cavity is prone to leakage

[0009] The plate roll described in Chinese patent application CN200820047269.5, this type of plate roll reduces thermal deformation to a certain extent, but this type of plate roll has only one layer of pipe along the axis, so the heat loss of this type of plate roll is fast, Not suitable for molding stripes that require constant temperature or high temperature for a long time
