Abstract
The utility model discloses a sectional middle shaft structure of air valve blades. Each air valve blade is disposed in inner middle of an air valve frame, and rotates with middle shafts as center; two sections of short middle shafts are disposed at two ends of the blade, with no middle shaft disposed in center of the blade; one end of the middle shaft is welded in a V-shaped groove of the blade, and extending end of the middle shaft is pivoted on the air valve frame. According to the utility model, existing whole middle shaft structure is obviated and only two sections of short middle shafts are disposed at two ends of the blade, to avoid unqualified linearity of very long middle shaft, and avoid stress deformation of blade due to multi-position welding.
Description
Technical field
The utility model relates to drying device field, axle construction in especially a kind of segmented of air-valve blade.
Background technique
The coating unit is used for base materials such as plastic pellicle, specialties, metal diaphragm are coated with, and is widely used in the high-end coating drying plant of products such as optical film, carbonless paper, water treatment reverse osmosis membrane, high efficiency particulate air filters film, solar energy backboard, positive electrode plate and negative electrode plate of lithium ion battery.In the inside of baking oven airduct or external ventilation pipeline, air-valve is installed usually, is used to regulate the size and the function that realizes opening and closing of ventilation.Blade has single leaf formula (referring to Fig. 1), leafy formula various ways such as (referring to Fig. 3), and like Fig. 1, shown in Figure 2, existing air-valve blade 2 all adopts whole axis 3 to be welded on the blade 2, then axis 3 two ends is installed in the inside of air-valve framework 1.Generally, axis 3 is long more, and straightness accuracy cannot say for sure to demonstrate,prove more; Secondly, solder joint is many more, is easy to generate the distortion of axle or blade more, and these mass defects have caused the sealing of blade to reduce, and can not effectively bring into play the effect of air-valve.
The model utility content
The applicant is whole to above-mentioned existing air-valve blade axis, and shortcomings such as flexible or welding stress deformation provide axle construction in a kind of segmented of air-valve blade rational in infrastructure, thereby avoid the generation of above-mentioned defective, effectively improve the air-valve sealing effect.
The technological scheme that the utility model adopted is following:
Axle construction in a kind of segmented of air-valve blade, air-valve blade are arranged on air-valve inside of frame central authorities, are the center rotation with the axis; The no axis of blade central authorities; Only be provided with the axis of two sections weak points at the blade two ends, an end of axis is welded in the V-shaped groove of blade, and extending end is articulated on the air-valve framework.
The beneficial effect of the utility model is following:
The utility model is cancelled existing whole middle axle construction; And the axis of two weak points only is set at the blade two ends; Thereby the undesirable problem of straightness accuracy of having avoided very long axis to produce, the problem that the blade stress of also having avoided the many places welding to produce simultaneously is out of shape.
Description of drawings
Fig. 1 is the plan view of existing technology air-valve.
Fig. 2 is an A-A sectional view among Fig. 1.
Fig. 3 is the plan view of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
As shown in Figure 3, the air-valve blade 2 of the utility model is arranged on the central interior of air-valve framework 1, can be center rotation with the axis, and when blade 2 deflects to horizontal position for opening distinguished and admirable path fully, vertical state is that wind path is closed.The axis of air-valve blade 2 is not whole one, but is respectively arranged with the axis 4 of two sections weak points in right ends, and 2/3 of axis 4 is welded in the V-shaped groove of blade 2, and extended 1/3 section is articulated on the air-valve framework 1.There is not axis in 3/5 part of blade 2 central authorities of the utility model; Only each part of 1/5 is provided with axis at two ends; Thereby the undesirable problem of straightness accuracy of having avoided very long axis to produce, the problem that the blade stress of also having avoided the many places welding to produce simultaneously is out of shape.During actual production, the axis 4 at two ends is on the center line when only needing to adopt anchor clamps to guarantee welding, promptly can fully guarantee the quality of blade and the sealing effect of air-valve.
Claims (1)
1. axle construction in the segmented of an air-valve blade; Air-valve blade (2) is arranged on the central interior of air-valve framework (1); With axis (4) is center rotation, it is characterized in that: the no axis of blade (2) central authorities is provided with the axis (4) of two sections weak points at blade (2) two ends; One end of axis (4) is welded in the V-shaped groove of blade (2), and extending end is articulated on the air-valve framework (1).
