The film substrate autosizing structure of adhesive tape
Technical field
The utility model relates to a kind of gumming mechanism, particularly relates to the film substrate automatic plastic body of adhesive tape.
Background technology
In the production process of adhesive tape, must be through this procedure of gluing.Finish the gluing machine complex structure of glue process at present, the gluing process all is to carry out in the online excellent gluing machine.Only establish a line rod in the previous line of the order rod gluing machine, and the line plane rod end in the line rod gluing machine is generally scraper, when carrying out gluing, easily film substrate scratched; Simultaneously, also easily cause the glue that applies on the film substrate in uneven thickness.
Summary of the invention
The utility model provides the glue thickness that applies on a kind of film substrate easy to control in order to overcome the deficiency of above-mentioned prior art, and can not scratch the film substrate autosizing structure of the adhesive tape of film substrate.
In order to achieve the above object, the film substrate autosizing structure of the utility model adhesive tape, it comprises frame, guide roller more than three is installed on the frame, the frame input is provided with gluing wheel, gluing wheel the latter half is immersed in the glue groove, the frame terminal is provided with winding wheel, film substrate is by the gluing wheel importing and to the gluing of gluing face, guide roller is located at the gluing face back side of film substrate, the gluing face of film substrate enters the circular arc end face of two line rods successively, is distributed with guide roller before and after the line rod, and output is towards the winding wheel direction after the film substrate gluing.
Described line rod is fixed on the frame.
In the utility model, by the glue thickness of line rod size control film substrate gluing face.When the gluing face of film substrate need apply thick glue layer, adopt thick line rod.The circular arc end face diameter of this line-transect rod is big, and gluing face is big with the circular arc end face contact area of line rod, reduces the pressure of the online excellent circular arc end face of gluing face, thereby applies the glue of a bed thickness on film substrate gluing face.Otherwise, when the gluing face of film substrate need apply thin glue layer, adopt thin line rod.The circular arc end face diameter of this line-transect rod is little, and gluing face diminishes with the circular arc end face contact area of line rod, increases the pressure of the online excellent circular arc end face of gluing face, thereby applies the thin glue of one deck on film substrate gluing face.
Adopt structure of the present utility model, gumming mechanism is simple in structure, and gluing is easy to operate.Be provided with plural line rod on frame, and change the line plane rod end into circular arc by original scraper, can not scratch the film substrate of adhesive tape in the gluing process like this, the glue layer of gluing face has applied evenly.Simultaneously, control the glue layer thickness of gluing face easily by line rod size.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is further elaborated:
Fig. 1 is the structural representation of the film substrate autosizing structure of the utility model adhesive tape.
The specific embodiment
As shown in Figure 1, the film substrate autosizing structure of the utility model adhesive tape, it comprises frame 2, guide roller 1 more than three is installed on the frame 2, frame 2 inputs are provided with gluing wheel 3, gluing wheel 3 the latter halfs are immersed in the glue groove 4, frame 2 terminals are provided with winding wheel 5, film substrate 6 is by gluing wheel 3 importings and to the gluing of gluing face, guide roller 1 is located at the film substrate 6 gluing face back sides, the gluing face of film substrate 6 enters the circular arc end face 8 of two line rods 7 successively, and line rod 7 front and back are distributed with guide roller 1, and output is towards winding wheel 5 directions after film substrate 6 gluings.
Described line rod 7 is fixed on the frame 2.
In the utility model, by the glue thickness of line rod 7 size control film substrates 6 gluing faces.When the gluing face of film substrate 6 need apply thick glue layer, adopt thick line rod 7.Circular arc end face 8 diameters of this line-transect rod 7 are big, and gluing face is big with circular arc end face 8 contacts area of line rod 7, reduce the pressure of the online excellent circular arc end face 8 of gluing face, thereby apply the glue of a bed thickness on film substrate 6 gluing faces.Otherwise, when the gluing face of film substrate 6 need apply thin glue layer, adopt thin line rod 7.Circular arc end face 8 diameters of this line-transect rod 7 are little, and gluing face diminishes with circular arc end face 8 contacts area of line rod 7, increases the pressure of the online excellent circular arc end face 8 of gluing face, thereby apply the thin glue of one deck on film substrate 6 gluing faces.
