Abstract

The invention discloses a vane device for cooling a film blowing machine, which comprises a main body, an air inlet pipe and an air outlet. The inner part of the main body is separated into a plurality of spaces by three layers of annular structures, and air ports are densely distributed on the annular structures. During work, air enters the main body from the air inlet pipe and passes through by means of the air ports layer by layer on the ring structures and finally reaches the air outlet and is blown off. The air blown off is adequate and uniform completely, thereby the cooling of the pipe film of the film blowing machine is very uniform.

吹膜机冷却用风环装置 Blown film cooling air ring device

技术领域 FIELD

[0001] 本发明涉及吹膜机配套装置,具体是一种吹膜机冷却用风环装置。 [0001] The present invention relates to a film blowing machine supporting means, in particular a cooling air ring blown film apparatus. 背景技术 Background technique

[0002] 冷却是吹膜机管膜制作过程中的关键环节,一般采用风环吹风冷却的方式。 [0002] is the key was cooled blown film tube in the film forming process, normally by means of blowing cooling air ring. 目前所用风环均为连接有多个进风管的中空结构,风从进风管进入风环再由风环内壁的出风口吹出,从而实现对吹膜机管膜吹风使其冷却的目的。 The air rings are currently connected with a plurality of intake duct hollow structure, air from the air inlet duct into the ring inner wall of the ring by the wind blow outlet, to achieve a film blowing machine blowing tube so cooling purposes. 但是这种风环吹出的风并不均勻,靠近进风管的出风口吹出的风较强,而离进风管较远的出风口吹出的风较弱,因而造成了吹膜机管膜的冷却不均,进而会在吹膜机管膜完全冷却后产生薄厚不均的现象,严重影响了吹膜机管膜的质量,产品不良率高。 However, this air ring blowing wind is not uniform, near the intake duct outlet strong wind blowing, and far away from the intake duct outlet air blown weak, resulting in a film blowing machine tube uneven cooling, and thus will produce uneven phenomenon after Bohou film blowing machine pipe cool completely, seriously affecting the quality of the film blowing machine pipe, high rate of defective products.

发明内容 SUMMARY

[0003] 本发明的目的在于提供一种出风均勻的吹膜机冷却用风环装置。 [0003] The object of the present invention is to provide a uniformity of the wind blown film cooling air ring device.

[0004] 本发明的具体技术方案是: [0004] The specific technical solution of the present invention is:

[0005] 一种吹膜机冷却用风环装置,包括主体、进风管及出风口,所述主体的内部由三层环状结构隔成多个空间,并且每层环状结构上密布风孔。 [0005] A blown film cooling air ring device, comprising a main body, inlet and outlet duct, inside the body of a three-layer structure is partitioned into a plurality of annular spaces, the cyclic structure and each wind clouds hole.

[0006] 所述进风管为多个,采用切向进风,沿主体周边均布。 [0006] The plurality of air inlet tube, tangential air inlet, along the periphery of the body uniform.

[0007] 所述环状结构是由不锈钢材料拼焊而成。 [0007] The cyclic structure is formed by a tailor-welded stainless steel.

[0008] 所述三层环状结构之间的间距相等。 Equal spacing between the three-ring structure [0008].

[0009] 工作时,风先从进风管进入主体,再通过环状结构上的风孔层层穿过,最后到达出风口并由此吹出。 When the [0009] work, start air inlet pipe into the body, through the vents and then through the layers of the cyclic structure, and thus finally reaches the outlet is blown out. 如此吹出的风充足且十分均勻,因此吹膜机管膜的冷却亦十分均勻;采用多个进风切向进风口,可根据供风管道的多少,将多外进风口并联后成一个进风管道相接, 使冷风的分布更加的均勻。 Thus the air blown out adequate and very uniform, and therefore the film tube cooled blown film is also very uniform; With a plurality of tangential inlet into the wind, according to the number of the supply duct, multiple parallel into an outer air inlet into the air contacting conduit, so that a more uniform distribution of the cool air.

[0010] 本发明的吹膜机冷却用风环装置具有如下有益效果:①构造简单,制造容易;② 巧妙设计出风在主体内的穿越路线,使得最后由出风口吹出的风非常均勻;③经其冷却后的吹膜机管膜冷却均勻,品质提高。 [0010] The cooled film blowing machine according to the present invention has the following advantages with air ring means: ① a simple structure, easy manufacture; ② cleverly devised through the wind path in the body, so that the last air blown from the outlet is uniform; ③ blown film through which the film tube is cooled uniformly cooled, improve quality.
