Abstract
The utility model discloses a folding water filter core hot melt face of weld structure, it includes shell and king-rod, the thickness of shell and king-rod all is 3mm, a right angle groove has been seted up along the circumferencial direction to the top inner wall of shell, the length and the width in right angle groove are 1.5mm, well core rod welds in the right angle inslot at the top of shell. The utility model discloses a folding water filter core hot melt welding face structure, open a 90 right angle at the hot melt welding position, make the melted PP solution volume of hot melt welding become less like this, and have a right angle groove, the phenomenon that solution extrudes can not appear, need not clear up the PP solution that extrudes, labour saving and time saving; the total length of the filter element can be better controlled, and the situation that the filter elements are different in length after hot-melt welding does not occur; finally, the situation that the integrity of the filter element is influenced by excessive solution extrusion is avoided.
Description
Technical Field
The utility model relates to a filter technical field especially relates to a folding water filter element hot melt face of weld structure.
Background
When traditional folding water filter core carries out the hot melt welding, the face of weld is in the same place through heating fusion and welding, but because the PP solution of section fusion is too much, can appear extruding the phenomenon, influences the integrality of filter core, and the outward appearance is unsightly moreover.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the problem that prior art exists with not enough, provide a novel folding water filter core hot melt face of weld structure.
The utility model discloses a solve above-mentioned technical problem through following technical scheme:
the utility model provides a folding water filter element hot melt face of weld structure, its characteristics lie in, it includes shell and king-rod, the thickness of shell and king-rod all is 3mm, a right angle groove has been seted up along the circumferencial direction to the top inner wall of shell, the length and the width in right angle groove are 1.5mm, well core rod welds in the right angle inslot at the top of shell.
The utility model discloses an actively advance the effect and lie in:
the utility model discloses a folding water filter core hot melt welding face structure, open a 90 right angle at the hot melt welding position, make the melted PP solution volume of hot melt welding become less like this, and have a right angle groove, the phenomenon that solution extrudes can not appear, need not clear up the PP solution that extrudes, labour saving and time saving; the total length of the filter element can be better controlled, and the situation that the filter elements are different in length after hot-melt welding does not occur; finally, the situation that the integrity of the filter element is influenced by excessive solution extrusion is avoided.
Drawings
Fig. 1 is a schematic structural view of a hot-melt welding surface structure of a folding water filter element according to a preferred embodiment of the present invention.
Fig. 2 is an installation diagram of the hot-melt welding surface structure of the folding water filter element according to the preferred embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 and 2, this embodiment provides a folding water filter core hot melt welding face structure, and it includes shell 1 and king-rod 2, the thickness of shell 1 and king-rod 2 all is 3mm, a right angle groove 3 has been seted up along the circumferencial direction to the top inner wall of shell 1, the length and the width in right angle groove 3 are 1.5mm, king-rod 2 welds in right angle groove 3 at the top of shell 1.
The following describes the manufacturing process specifically:
one, well core rod 2 and the shell 1 of filter core are through the hot melt welding, and the date melts 1.5mm, and well core rod 2 and the thickness of shell 1 are 3mm, so only need to revise well core rod 2 and the injection mold of shell 1, weld the right angle groove 3 that contact surface position adds a length and width 1.5mm again.
And secondly, assembling the central rod 2, the shell 1, the paper core 4, the end cover 5 and the flat head 6, and putting the assembled components into a hot melt welding machine for welding.
And thirdly, the welding surface is heated during welding, and due to the fact that a right angle is formed, the melting volume is small, the melting amount of the solution is small, the extrusion phenomenon cannot occur, and the length of the filter element is well controlled.
Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
