An intermittent foaming microporous sheet leveling device

Abstract

The invention provides an intermittent foaming microporous sheet leveling device, which belongs to the field of mechanical technology. The intermittent foaming microporous sheet leveling device includes a cleaning device and a leveling transmission mechanism connected to the cleaning device. The cleaning device includes a cleaning roller mechanism carrying the intermittent foaming microporous sheet. The cleaning roller mechanism includes a cleaning upper transmission bearing. , a clean lower transmission bearing arranged in parallel with the clean upper transmission bearing, a clean upper transmission shaft that runs through the clean upper transmission bearing, and a clean lower transmission shaft that is arranged in parallel with the clean upper transmission shaft and runs through the clean lower transmission bearing, and the clean lower transmission bearing There is a cleaning support piece on it, and the cleaning support piece is connected with the leveling transmission mechanism. The intermittent foaming microporous sheet leveling device has the advantages of simple structure, wide application range and high work efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a leveling device, in particular to a leveling device for intermittent foaming microporous sheets. Background technique [0002] Microcellular plastic is a new type of foamed plastic with a cell diameter of 0.1-10 μm and a cell density of 10 9 ~10 15 / cm 3 In between, the density of the material can be reduced by 5% to 98% compared with that before foaming. When the free volume and defects in the polymer can be replaced by some tiny pores, the micropores will reduce the stress concentration inside the material, thereby optimizing and improving the impact resistance of the material. [0003] In recent years, the research on microporous plastics has become more and more extensive. Great research results have been achieved in both raw material improvement and process equipment transformation. Microporous plastics have the advantages of ultra-light, heat insulation, sound absorpti...

Problems solved by technology

In view of the fact that the processed microporous sheet is easy to wrinkle and cannot be directly applied to the production of actual products, but requires subsequent processes for leveling and pressing, the structure and process of the leveling device have always been the technology for the industrial application of this type of sheet. difficulty

Although the existing sheet leveling device is capable of conveying and hot-pressing the sheet, it cannot effectively remove water, oil and other sundries before hot-pressing, and the sheet cannot be well attached to the roller , which affects the uniformity of sheet leveling, and the production efficiency is low; at the same time, it cannot effectively ensure the uniform thickness of the sheet when it enters the calender, which will cause a large difference in the proportion of different regions of the sheet and wrinkles on the surface; it cannot effectively ensure that the sheet The stability and flatness of the material before entering the calender will have a great influence on the calendering process of the subsequent calendering.
