Abstract
The utility model provides a vacuum thread flattening roller, comprising a roller body, wherein a left hand thread and a right hand thread are symmetrically arranged from the center of the surface of the roller body to the two sides; the roller body is a barrel body with two closed ends; the barrel body is provided with a connector connected with a negative pressure source; and inter-grooves of the left hand thread and the right hand thread are provided with adsorption holes communicated with an inner cavity of the barrel body. According to the vacuum thread flattening roller disclosed by the utility model, the roller body of the thread flattening roller is designed into the barrel body, the barrel body is connected with vacuum equipment and the inter-grooves of the left hand thread and the right hand thread are provided with the adsorption holes, so that on one hand, the contact with the surface of the roller body can be realized by self tension of a membrane and then the membrane is flattened; and on the other hand, when the membrane is too thin to contact with the surface of the roller body better, the effect of the adsorption holes is utilized to enhance abrasion force of the membrane on the surface of the roller body and the flattening effect is achieved, so that the flattening effect of the thread flattening roller is wholly enhanced.
Description
Technical field
The utility model relates to a kind of vacuum screw thread leveling roller that uses for the microporous membrane coating technique.
Background technology
Existing screw thread leveling roller, its general structure is that surface at roll body is from mediad bilateral symmetry distribution left and right hand thread, when base material contact screw thread leveling roller surperficial, produce friction with the lip-deep screw thread that tilts to both sides of screw thread leveling roller, the screw thread that tilts is able to base material open and flat at the two ends of base material expansion to the screw thread leveling roller.This screw thread leveling roller, for usually thicker base material, the effect of its flattening or more satisfactory is as for the production of agricultural film etc.But, if this screw thread leveling roller be used in produce in lithium cell every thin, mostly only has 8u-30u due to this each every thin, the film of this thickness is want to make itself and the friction increase of screw thread leveling roller by strengthening membrane tension, improve the flattening effect of screw thread leveling roller, just must make the distortion of barrier film length direction.Therefore, not too suitable being directly used in of this screw thread leveling roller flattens the barrier film of thickness at 8u-30u, after needing to be improved, just can use.
The utility model content
In order to overcome the problems referred to above, the utility model provides a kind of to society can improve the vacuum screw thread leveling roller that barrier film flattens effect.
The technical solution of the utility model is: a kind of vacuum screw thread leveling roller is provided, comprise roll body, surface at described roll body is provided with left and right hand thread from the mediad bilateral symmetry, described roll body is the cylindrical shell of closed at both ends, described cylindrical shell be provided with the joint that is connected with negative pressure source, be provided with the adsorption hole that communicates with cylinder lumen in groove between described left and right hand thread.
As to improvement of the present utility model, described adsorption hole increases to two ends density gradually in central authorities.
The utility model is owing to having adopted the roll body with the screw thread leveling roller to be designed to cylindrical shell, and cylindrical shell is connected with vacuum apparatus, and be provided with adsorption hole in groove between left and right hand thread, like this, can realize relying on the one hand tension force and the roll body Surface Contact of barrier film self, and flatten, on the other hand, when barrier film too thin and can not be well and during the roll body Surface Contact, can utilize the effect of adsorption hole to increase the friction of barrier film pair roller surface, and reach the effect of flattening, strengthened on the whole the flattening effect of screw thread leveling roller.
Description of drawings
Fig. 1 is the planar structure schematic diagram of a kind of embodiment of the present utility model.
The specific embodiment
See also Fig. 1, what Fig. 1 disclosed is a kind of vacuum screw thread leveling roller, comprise roll body 1, surface at described roll body 1 is provided with left and right hand thread 11,12 from the mediad bilateral symmetry, described roll body 1 is the cylindrical shell of closed at both ends, described cylindrical shell be provided with the joint that is connected with negative pressure source, described left and right hand thread 11,12 between be provided with the adsorption hole 13 that communicates with cylinder lumen in groove.During use, joint is connected with vacuum source, starting vacuum screw thread leveling roller just can work, contact friction due to barrier film from central authorities to two ends reduces gradually, so it is the structure that increases gradually in central authorities to two ends density that the utility model preferably is designed to described adsorption hole 13, is conducive to like this improve the flattening effect of vacuum screw thread leveling roller.
The utility model is owing to having adopted the roll body with the screw thread leveling roller to be designed to cylindrical shell, and cylindrical shell is connected with vacuum apparatus, and be provided with adsorption hole in groove between left and right hand thread, like this, can realize relying on the one hand tension force and the roll body Surface Contact of barrier film self, and flatten, on the other hand, when barrier film too thin and can not be well and during the roll body Surface Contact, can utilize the effect of adsorption hole to increase the friction of barrier film pair roller surface, and reach the effect of flattening, strengthened on the whole the flattening effect of screw thread leveling roller.
