Abstract

The invention provides an embossing or calendering device, which comprises an embossing or calendering roller, at least one smooth roller cooperated with the embossing or calendering roller for embossing or calendering and a jacking device for driving the smooth roller to be tightly attached to the embossing or calendering roller, wherein the smooth roller can be flexibly deformed to keep tight attachment to the embossing or calendering roller under the driving and pressing action of the jacking device. After the above structural form is adopted, since the smooth roller is always jacked by the jacking device during embossing or calendering and the rigidity of the smooth roller is relatively low, when a gap exists at a position between the embossing or calendering roller and the smooth roller, the corresponding part of the smooth roller is jacked by the jacking device to immediately deform, so that the gap at the position disappears, and the uniformity of the embossing or calendering effect of a flexible material is ensured.

Description

A kind of embossing or calendering device

Technical field

The present invention relates to the processing technique field such as paper, non-woven fabrics, leather, particularly relate to a kind of embossing or pressure

Electro-optical device.

Background technology

Embossing or felt wrapped roll generally by adopting steel in the embossing or burnishing process of the flexible materials such as paper, non-woven fabrics, leather coordinate with smooth roll carries out embossing or press polish, in order to embossing or the press polish quality of above-mentioned flexible material, the end face machining accuracy of embossing or felt wrapped roll and smooth roll is more high better, so that embossing or felt wrapped roll can be fitted completely with smooth roll when making embossing or press polish, thus ensure embossing effects uniformity.But in practice, longer owing to carrying out the embossing of embossing or calendering applications or felt wrapped roll and its axial dimension of smooth roll, be difficult to the machining accuracy ensureing its entirety; In addition, because embossing during operation or felt wrapped roll and smooth roll are in high-speed rotation state, embossing or there is play between felt wrapped roll and smooth roll, thus also cannot avoid flexible material local embossing or uneven phenomenon.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, when providing a kind of cost lower and effectively can ensure that embossing works, embossing or felt wrapped roll fit tightly with smooth roll the embossing or calendering device that coordinate completely.

For achieving the above object, technical scheme provided by the present invention is: a kind of embossing or calendering device, comprise embossing or felt wrapped roll, also comprise at least one and coordinate the smooth roll of embossing or press polish and the jack unit for driving described smooth roll and embossing or felt wrapped roll to fit tightly with described embossing or felt wrapped roll, wherein said smooth roll, under the driving pressuring action of described jack unit, enables smooth roll produce soft change and described embossing or felt wrapped roll and keeps fitting tightly.

Preferably, described jack unit is one or more groups spaced top pressure assembly, each top pressure assembly comprises top and stretches cylinder, stretched support and the pair of bearings that is positioned on these support two ends that cylinder drives by this top, and wherein said smooth roll forms to roll and is connected between this pair of bearings and with this pair of bearings.

This programme carries out embossing or press polish by adopting the elongated smooth roll that deformation occurs after pressurized with may correspond to coordinate with embossing or felt wrapped roll, wherein this smooth roll is driven by corresponding jack unit, to make bachelor moment and embossing or felt wrapped roll can be in complete fit-state.After adopting said structure form, because the smooth roll moment is subject to the top pressure effect of jack unit when embossing or press polish, and smooth roll stiffness by itself is less, when embossing or between felt wrapped roll and smooth roll there is gap in somewhere time, this place that smooth roll is corresponding produces deformation to make the gap at this place disappear at once owing to being subject to the top pressure effect of jack unit, thus ensures the uniformity of flexible material embossing or the calendaring effect.

Detailed description of the invention

Below in conjunction with specific embodiment, the invention will be further described:

Shown in accompanying drawing 1 to accompanying drawing 3, a kind of embossing described in the present embodiment or embossing device.This embossing or calendering device comprise embossing or felt wrapped roll 1(when carrying out embossing work, and this roller is the roller of a roll surface predetermined pattern or texture; When carrying out calendering applications, this roller is the bachelor that a roll surface is smooth.), at least one to coordinate the smooth roll 2 of embossing and the jack unit 3 for driving above-mentioned smooth roll 2 to fit tightly with embossing or felt wrapped roll 1 with this embossing or felt wrapped roll 1, wherein in order to ensure that smooth roll 2 is under the top pressure effect of jack unit 3, it can produce deformation everywhere to fit with embossing or felt wrapped roll 1 to smooth roll 2, smooth roll 2 preferably adopts leptosomatic version, usually constant in material or when changing little, the diameter of smooth roll 2 is less than the diameter of embossing or felt wrapped roll 1.

Again see shown in accompanying drawing 1 and 3, preferably in the present embodiment, above-mentioned jack unit 3 is the many groups of top pressure assemblies 31 being arranged at intervals at immediately below above-mentioned smooth roll 2, each top pressure assembly 31 comprises top and stretches cylinder 313, stretched the support 312 that cylinder 313 drives and the pair of bearings 311 (also can adopt roller or other rolling member) be positioned on these support about 312 two ends by this top, and wherein smooth roll 2 forms Structure deformation with this pair of bearings 311 between this pair of bearings 311.

Shown in accompanying drawing 3, during work, at embossing or the flexible material between felt wrapped roll 1 and smooth roll 24 in embossing or burnishing process, jack unit 3 is in jacking impaction state to smooth roll 2 all the time.When embossing or between felt wrapped roll 1 and smooth roll 2 there is gap in somewhere time, this place corresponding on smooth roll 2 produces deformation at once owing to being subject to the top pressure pressuring action of jack unit 3, upwards laminating is so that embossing or felt wrapped roll 1 keep close contact to eliminate gap, ensures embossing or press polish quality.

The embodiment of the above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention.Any those of ordinary skill in the art, are not departing under technical solution of the present invention ambit, the technology contents of above-mentioned announcement can utilized to make more how possible variation and retouching to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Therefore all contents not departing from technical solution of the present invention, the equivalent equivalence change that the thinking according to the present invention is done, all should be covered by protection scope of the present invention.
