In the above drawings: 1. a pinch roller; 2. trimming knives; 3. a mounting frame; 4. a slide bar; 5. and a screw rod.
Detailed Description
As shown in fig. 1, an embodiment of the present invention discloses a trimming device for a door panel welting machine, including:
the pressing wheel 1 is abutted against and vertically extrudes the welt surface of the door panel, and the edge of the wheel surface is tangent to the edge of the door panel;
the edge of the trimming knife 2 is abutted against the edge of the door panel, and the abutting point is the tangent point of the edge of the pressing wheel 1 and the edge-attaching surface of the door panel;
the pinch roller and the trimming knife are arranged at the downstream section of the welting machine.
The relative positions of the pressing wheel 1, the trimming knife 2 and the door panel are well adjusted before use, the door panel continuously moves forwards along with the operation of the edge pasting machine, and the pasted edge strips are scraped by the trimming knife 2 under the stabilizing effect of the pressing wheel 1.
Preferably, the extension direction of the blade or the tangential direction of the contact point of the blade and the edge strip forms an acute angle with the welt surface of the door panel, so that the pressure of the edge strip on the edge strip when the door panel moves can be decomposed into a direction opposite to the movement of the door panel and a direction in which the edge strip points to the door panel. The extension direction or the tangential direction of cutting edge and the contained angle of door plant moving direction make the decomposition of the effect of sword to the strake also press the strake to the door plant when cutting open the strake to further reduce the possibility of pruning in-process strake perk.
Preferably, the edge of the pressing wheel 1 is thick, the center of the pressing wheel is thin, the side surface of the pressing wheel 1 is provided with a conical recess, and one side of the trimming knife 2 close to the center of the pressing wheel 1 inclines towards the recess. The conical depression of the pinch roller 1 leaves sufficient space for the oblique mounting of the trim blade 2, while the oblique mounting of the trim blade 2 avoids to the greatest extent possible scratching of the door panel surface.
Preferably, as shown in fig. 2, the trimming knife 2 is a circular knife, and is driven by a motor to rotate, the rotation direction of the cutting edge at the contact point of the cutting edge and the edge strip is from the edge strip to the door panel, the side of the knife body from the edge strip to the door panel is a minor arc, and the side of the knife body from the edge strip to the door panel is a major arc. The limitation of the contact point of the circular knife and the edge strip during cutting and the limitation of the rotation direction of the circular knife enable the edge strip to be subjected to the force of extruding the door panel during cutting, and therefore the possibility of tilting of the edge strip during trimming is reduced.
Preferably, a set of pinch roller 1 and a set of trimming knife 2 are respectively arranged at two edges of the door panel to be trimmed.
Preferably, one set of the pinch roller 1 and the trimming knife 2 is arranged on a mounting frame 3, and the mounting frame 3 is provided with a height adjusting device. Because the door plate is usually in a flat state when being welted, the trimming device can be suitable for the door plates with different thicknesses only by setting a set of pressing wheel 1 and trimming knife 2 above to be adjustable in height.
Preferably, the height adjustment means comprises a slide rod 4 passing through and slidably connected to the mounting frame 3 and a screw 5 threadedly connected to the mounting frame 3. The screw rod 5 is rotated to enable the mounting frame 3 to slide along the slide rod 4 so as to adjust the positions of the pressing wheel 1 and the trimming knife 2 and adapt to door panels with different thicknesses.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
