Tracking and trimming means of automatic edge sealing machine

Abstract

The invention provides a tracking and trimming means of automatic edge sealing machine, belongs to the carpentry machinery field, solves the problems of complex construction, instable gravity center, easily damage to cylinder, asynchronous motions of patterning wheel, patterning plate and milling cutter driven by different cylinders, and poor cutting precision existing in current trimming devices. The tracking and trimming means of automatic edge sealing machine comprises a base, a tracking mechanism capable of causing the edge of the milling cutter mounted on the base to move along the edge of the edge sealing band pasted on the plate side; the milling cutter is driven by a motor. The invention is characterized in: The tracking mechanism comprises a vertical shaft and a lifting slide carriage disposed out of the vertical shaft; the vertical shaft is connected with a translation mechanism capable of driving it to move levelly; and the motor is levelly fixed on the lifting slide carriage. The invention realizes milling cutter tracking simply by combining two linear kinematic pair: a level kinematic pair and a vertical kinematic pair, has a simple construction and stable gravity center.

Description

technical field [0001] The invention relates to an automatic edge banding machine, in particular to a tracking and trimming device of the automatic edge banding machine, which belongs to the field of woodworking machinery. Background technique [0002] In woodworking machinery, in order to make the sides of the board as beautiful and smooth as the upper and lower surfaces, the four sides of the board are usually edge-banded so that the exposed wood texture is hidden, but after edge banding, The edges around the edge banding are very sharp, which is easy to scratch hands and clothes, so it needs to be trimmed with a fillet milling cutter. The traditional trimming technology is to process the horizontal edge and the vertical edge of the edge banding separately, which has the disadvantages of low efficiency and poor precision. In order to overcome the above defects, Chinese Patent No. ZL200720050982.0 discloses a trimming The device is completed by two sets of devices. The fir...

Problems solved by technology

[0002] In woodworking machinery, in order to make the sides of the board as beautiful and smooth as the upper and lower surfaces, the four sides of the board are usually edge-banded so that the exposed wood texture is hidden, but after edge banding, The edges around the edge banding are very sharp, which is easy to scratch hands and clothes, so it needs to be trimmed with a rounded end milling cutter

The traditional trimming technology is to process the horizontal edge and the vertical edge of the edge banding separately, which has the disadvantages of low efficiency and poor precision. In order to overcome the above defects, Chinese Patent No. ZL200720050982.0 discloses a trimming The device is completed by two sets of devices. The first set of devices is used to complete the R edge milling of the left lower part of the plate, the lower part of the plate, and the lower right of the plate; the second set of devices is used to complete the upper left part of the plate, the upper part of the plate, and the right side of the plate. The upper R edge milling, each set of devices uses 5 cylinders, the end of the piston rod of the No. The end of the rotary slider seat, the No. 3 cylinder is fixed on the rotary slider, and the No. 2 and No. 3 cylinders are connected by a piston rod; the profiling milling device (including the motor, the milling cutter connected to the output shaft of the motor, and the milling cutter The outer cam wheel and the cam plate containing the milling cutter) are fixed on the slide plate through a V-shaped pressure plate, and the rotary slide block and the slide plate are connected by linear slide rails. The No. 4 cylinder is fixed on the rotary slide block, and the No. 5 cylinder is fixed on the On the slide, cylinder No. 4 and cylinder No. 5 are connected by piston rod

It has the following defects: first, the No. 1 cylinder drives the rotary slider seat on the top to rotate synchronously with the rotary slider, the other 4 cylinders, and the profiling milling device. The top is heavy and the bottom is light, the center of gravity is unstable, and it is easy to damage No. 1 cylinder; second, the former wheel, template and milling cutter are driven by different cylinders, the movements are not synchronized, and the milling accuracy is poor; third, the whole device is driven by five cylinders, the structure is complicated and the cost is high
