Detailed description of the invention
Attached drawing 1 is that the present invention is a kind of for carrying out the structure chart of the device of glue spraying in the folding line position of folded membrane.
In figure: 1 X shifting axle, 2 Y shifting axles, 3 folded membrane pipelines, 4 nozzles, the folding position of 5 folded membranes.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, with reference to the accompanying drawing to specific reality of the invention The mode of applying is described in further detail.
Core of the invention thought is to spray quick-drying gelatin in the folding position of folded membrane, for substituting glue in the prior art Band, while providing a kind of technique and method for spraying quick-drying gelatin.
As shown in Fig. 1, a kind of for carrying out the device of glue spraying, including folded membrane pipeline in the folding line position of folded membrane 3, nozzle 4 and right angle shifting axle, folded membrane pipeline 3 are located at the lower section of right angle shifting axle.The glue supplied in nozzle in the present invention For quick-drying gelatin.
Wherein, right angle shifting axle includes X shifting axle 1 and Y shifting axle 2, and the angle between X shifting axle and Y shifting axle is 90 degree.X shifting axle 1 is fixed, and includes track I on X shifting axle 1, and Y shifting axle 2 is slided along track I;Nozzle 4 is located at Y shifting It include track II on Y shifting axle 2 on moving axis, nozzle 4 is slided along track II.The initial position of nozzle 4 is located on Y shifting axle far Side from X shifting axle, the initial position of Y shifting axle 2 are located at the side on X shifting axle 1 close to folded membrane input port;Work as folding When the folding line position 5 of film reaches the initial position of nozzle 4 along folded membrane pipeline, folded membrane moves forward, Y shifting axle 2 keep the same direction and speed to slide along track I and folded membrane, meanwhile, nozzle 4 is along track II towards the other side of Y shifting axle 2 Sliding carries out glue spraying to the folding line position of folded membrane.
It is worth noting that above-mentioned X shifting axle and Y shifting axle can be interchanged, and as long as being capable of forming right angle shifting axle, life Name does not interfere with the present invention.In addition, the position of nozzle can be as shown in Fig. 1, it is mobile that the initial position of nozzle 4 is located at Y Far from the side of X shifting axle on axis, slided during glue spraying towards close to the mobile axis direction of X;It is mobile Y can also to be located at Close to the side of X shifting axle on axis, slided during glue spraying away from the mobile axis direction of X.As long as nozzle can be real Present sliding process slides into the other end from one end of the folding position of folded membrane.Shifting axle where nozzle is needed from folding Fold the delivery outlet that the input port of film follows folded membrane to slide into folded membrane, wherein the input port of folded membrane and delivery outlet refer to The position of its into or out glue-spraying device of the present invention.
X-axis is fixed in the present invention, and Y shifting axle and nozzle are slided, and in sliding process, can be watched using X-axis Taking motor drives Y shifting axle to slide along track I;Y-axis servo motor drives nozzle to slide along track II.Quick-drying gelatin in the present invention The speed that thickness can slide by adjusting nozzle along track II controls, and nozzle slides faster, the thickness of the quick-drying gelatin of spraying Degree is thinner, and the thickness that nozzle slides slower, to spray quick-drying gelatin is thicker.The width of quick-drying gelatin can pass through nozzle in the present invention Model, that is, nozzle width in the X-axis direction adjust, numerical value of the width between 40-50mm can be set.
A kind of method of glue spraying provided by the invention, includes the following steps:
S01: Y shifting axle and nozzle are placed on initial position, wherein the initial position of nozzle is located at the one of Y shifting axle Side, the initial position of Y shifting axle are located at the side on X shifting axle close to folded membrane input port;X shifting axle is fixed.
S02: folded membrane pipeline Foldable film enters device, when the folding line position of folded membrane is located at below nozzle, Folded membrane moves forward, and Y shifting axle keeps the same direction and speed to slide along track I and folded membrane, meanwhile, nozzle is along rail Road II carries out glue spraying to the folding line position of folded membrane towards another Slideslip of Y shifting axle.
Wherein, above-mentioned X shifting axle and Y shifting axle can be interchanged, and the initial position of nozzle can be located at separate on Y shifting axle The side of X shifting axle is slided during glue spraying towards close to the mobile axis direction of X;It can also be located at close on Y shifting axle The side of X shifting axle is slided during glue spraying away from the mobile axis direction of X.
S03: when folded membrane pipeline Foldable film reaches folded membrane delivery outlet, folded membrane folding line position is uniformly sprayed Glue.The thickness of quick-drying gelatin can slide by adjusting nozzle along track II in the present invention speed controls, nozzle slide it is faster, The thickness of its quick-drying gelatin sprayed is thinner, and the thickness that nozzle slides slower, to spray quick-drying gelatin is thicker.Quick-drying gelatin in the present invention Width can be adjusted by the width of model, that is, nozzle of nozzle in the X-axis direction, it is 40-50mm that the width, which can be set, Between numerical value.
The present invention using nozzle folding position spray quick-drying gelatin, and spray-bonding craft in the transmission process of folded membrane into Row greatly reduces the time of glue spraying transport, it is ensured that the width and thickness uniformity for the quick-drying gelatin that folding position is sprayed-on;? Different glue spraying thickness can adjust by the speed of control nozzle walking under the premise of hardware is constant, it can by control nozzle width Adjust glue spraying width;It follows folded membrane to move together by adjusting shifting axle and nozzle, reaches synchronous transport and glue spraying, save life Produce time raising production efficiency;And quick-drying gelatin will not be fallen off in use, so that the strainability of filter core is always It is consistent.
The above description is only a preferred embodiment of the present invention, and the embodiment is not intended to limit patent protection of the invention Range, thus it is all with the variation of equivalent structure made by specification and accompanying drawing content of the invention, it similarly should be included in this In the protection scope of invention appended claims.
