Description

Edge finishing mechanism of edge banding machine

The invention relates to an edge trimming mechanism of an edge banding machine, specifically, an edge trimming mechanism that can be applied to workpieces with concave holes on the surface.

The traditional edge banding machine can refer to the invention patent No. I671237 applied by the applicant. Please refer to Figure 1, which illustrates an edge banding machine, which includes a body, a set of slide rails, and a set of positioning rollers And a plurality of other mechanisms (including pre-milling mechanism, gluing mechanism, side strip conveying mechanism, horizontal pressing roller group and lower repairing mechanism). The slide rail is movably arranged on the base body, the positioning pressure roller set is arranged above the slide rail, and the workpiece to be processed is clamped between the slide rail and the positioning pressure roller set and can be moved. The pre-milling mechanism will do preliminary processing on the surface of the workpiece, the gluing mechanism will apply glue to the surface of the workpiece, the edge strip conveying mechanism is used to transmit the edge strip to the workpiece after gluing, and the edge banding machine passes through the tool (not shown in the figure) ) to cut the side strip, and press the cut side strip to the workpiece through the horizontal pressure wheel group, so that the cut side strip can be tightly bonded with the glued workpiece. Finally, the edge banding machine also trims the edge strips through the edge strip finishing mechanism (usually including an upper trimming mechanism (not shown in the figure) and a lower trimming mechanism), so as to trim the excess parts of the cut edge strips and Chamfers the end edges of the side strips.

In the process of edge trimming using the edge trimming mechanism, it is necessary to use the profiling wheel to keep the scraper of the edge trimming mechanism at a fixed height relative to the workpiece, so as to avoid the appearance on the edge of the edge during trimming flaw. However, some workpieces with special structures, such as cabinet door panels (such as the cabinet door panel 71 shown in the third figure of Taiwan Publication No. M367645 New Patent), usually need to cut a hole on the upper surface of the workpiece to install hinges. When the workpiece with the above-mentioned holes passes through the simulation of the edge finishing mechanism When forming the wheel, the copying wheel may sink into the above-mentioned hole, causing improper vertical displacement of the scraper, which will cause cosmetic defects in the edge strip.

One of the purposes of the present invention is to improve the lack of the edge trimming mechanism of the existing edge banding machine, and then propose a brand-new structural design of the edge trimming mechanism of the edge banding machine, which can reduce the time spent on trimming. Cosmetic blemishes at the end edge of a strip.

The reason is that according to the edge finishing mechanism of an edge banding machine provided by the present invention, it is applied to a workpiece with a side strip attached thereto.

The above-mentioned scraper is arranged on the fixed seat and is located between the side profiling wheel and the upper profiling wheel group to trim one end edge of the above-mentioned side bar.

In this way, in the process of edge trimming using the edge trimming mechanism, if there are holes in the structural design of the workpiece, even if one of the profiling wheels of the upper profiling wheel set is located at the position of the hole during the movement of the workpiece, The edge trimming mechanism can still maintain the position of the scraper relative to the edge through another contouring wheel of the upper contouring wheel set, so it can effectively reduce the appearance defects of the edge of the edge in the trimming process.

In one aspect, the above-mentioned trimming mechanism for edge strips can be an upper trimming mechanism or a lower trimming mechanism for trimming the upper edge or the lower edge of the edge strips respectively.

In another aspect, the fixing part of the upper copying wheel set is rotatably arranged on the fixing seat, so as to adjust the height positions of the first and second upper copying wheels synchronously.

Specifically, the fixed seat also includes a mounting portion, and the mounting portion has two adjusting screw holes arranged at intervals. The above two adjusting screw holes are respectively located at the front and rear ends of the mounting portion, and the two adjusting screws are arranged on the above two adjusting screw holes. hole, and the ends of the above two adjustment screws abut against the fixing piece. Through the above-mentioned two adjusting screws, the inclination angle of the fixing member can be adjusted, so as to adjust the height positions of the first and second upper profiling wheels.

Specifically, the fixing member also includes a straight plate and a horizontal plate, the horizontal plate is connected to the upper end of the straight plate, the ends of the two adjustment screws abut against the horizontal plate, the first and second upper profiling wheels are vertical and It is rotatably arranged on the above-mentioned straight plate.

In another aspect, the fixed base also includes a scraper installation groove, the scraper structurally includes a knife seat and a blade, the knife seat includes a vertical section and an inclined section, the vertical section is vertically movable in the above scraper installation groove The inclined section is connected to the lower end of the vertical section and extends towards a junction between the side profile wheel and the upper profile wheel set, and the blade is arranged at the end of the inclined section. The position of the scraper relative to the end edge of the edge strip can be effectively adjusted through the scraper installation groove.

Specifically, the fixing seat is also provided with a fixing screw hole, and the above-mentioned vertical section is provided with an elongated hole, and a fixing screw passes through the above-mentioned elongated hole and is screwed into the fixing screw hole, so as to better adjust and fix the position of the scraper.
