Title (EN) EXTRUSION HEAD, COATING APPARATUS AND COATING SYSTEM
(FR) TÊTE D'EXTRUSION, APPAREIL D'ENDUCTION ET SYSTÈME D'ENDUCTION
(ZH) 挤压头、涂布装置及涂布系统
Abstract:
(EN) Provided is a coating system, comprising an extrusion head, a transition roller, a base material and a drying oven, wherein the base material spans the transition roller and passes from the transition roller through the extrusion head and the drying oven in the direction of transfer of the base material. The head part of the extrusion head faces the base material and the extrusion head comprises an extrusion head lower lip and an extrusion head upper lip. In the direction of transfer of the base material, the extrusion head upper lip is arranged at the front end, and a channel provided for passing a paste is arranged between the extrusion head upper lip and the extrusion head lower lip. The extrusion head is further provided with a cavity, paste flowing from outside into the cavity and the cavity communicating with the channel. The head part of the extrusion head lower lip is higher than the head part of the extrusion head upper lip and the extrusion head lower lip has rounded corners. Particularly provided are a coating apparatus and an extrusion head, such that the extrusion head can directly coat suspended base material with paste, thereby achieving the possibility of coating on two sides. Using upper and lower pressure rollers to clamp the two sides of the base material at the margins respectively, a single layer drying oven can dry the two sides simultaneously, saving on energy consumption by more than 50%, and saving on the time needed to replace the material. The structure is compact and the efficiency of the device is increased.
(FR) L'invention porte sur un système d'enduction, comprenant une tête d'extrusion, un rouleau de transition, un matériau de base et une étuve de séchage, le matériau de base passant sur le rouleau de transition et passant à partir du rouleau de transition dans la tête d'extrusion et l'étuve de séchage dans la direction de transfert du matériau de base. La partie de tête de la tête d'extrusion est en regard du matériau de base et la tête d'extrusion comprend une lèvre inférieure de tête d'extrusion et une lèvre supérieure de tête d'extrusion. Dans la direction de transfert du matériau de base, la lèvre supérieure de la tête d'extrusion est disposée à l'extrémité avant et un canal prévu pour faire passer une pâte est disposé entre la lèvre supérieure de la tête d'extrusion et la lèvre inférieure de la tête d'extrusion. La tête d'extrusion est en outre dotée d'une cavité, la pâte s'écoulant de l'extérieur dans la cavité et la cavité communiquant avec le canal. La partie de tête de la lèvre inférieure de la tête d'extrusion est supérieure à la partie de tête de la lèvre supérieure de la tête d'extrusion et la lèvre inférieure de la tête d'extrusion a des coins arrondis. En particulier, l'invention porte sur un appareil d'enduction et sur une tête d'extrusion, conçus de façon telle que la tête d'extrusion peut directement enduire un matériau de base suspendu de pâte, ce qui donne de cette manière la possibilité d'appliquer une enduction sur deux côtés. A l'aide de rouleaux de pression supérieur et inférieur pour fixer les deux côtés du matériau de base au niveau des marges respectivement, une étuve de séchage monocouche peut sécher les deux côtés simultanément, ce qui permet d'économiser plus de 50 % de la consommation d'énergie et d'économiser le temps nécessaire pour remplacer le matériau. La structure est compacte et le rendement du dispositif est accru.
(ZH) 一种涂布系统,包括挤压头、过渡辊、基材和烘干箱,基材跨设在过渡辊上并由过渡辊沿基材传动方向经过挤压头和烘干箱,挤压头的头部朝向基材,挤压头包括挤压头下唇和挤压头上唇,沿基材传动方向挤压头上唇设置在前端,挤压头上唇与挤压头下唇之间设置有供浆料通过的通道,挤压头还设置有腔体,腔体从外界通入浆料并与通道相通,挤压头下唇的头部高于挤压头上唇的头部,挤压头下唇的头部为圓角,具体的提供一种涂布装置及挤压头,使挤压头可以直接将浆料涂覆在悬空的基材上,从而实现双面涂布的可能,采用上下压辊分别夹持基材的两侧边空白处,单层烘箱即可同时烘干双面,节约能耗50%以上,并节约更换物料的时间,结构紧凑,提高设备效率。
