Leakage-proof device of gluing mechanism of edge bonding machine

Abstract

The invention discloses a leakage-proof device of a gluing mechanism of an edge bonding machine. The leakage-proof device comprises a glue supplying box, a gluing shaft, a glue supplying wheel seat, a sealing cover between the glue supplying wheel seat and the gluing shaft, an O-shaped sealing ring and a bearing, wherein the gluing shaft comprises a gluing shaft working part and a gluing shaft connecting part, which are fixedly connected with each other, a spiral lifting groove of which the spiral direction is opposite to the rotating direction of the gluing shaft is formed in the outer wall surface of the gluing shaft working part, and the sealing cover is used for receiving leaked glue; glue is actively elevated into the glue supplying box from a receiving groove and a long and thin gap by rotation of the lifting groove in a rotating process of the gluing shaft, so that a condition that glue enters the bearing to cause locking is effectively avoided, and even if a sealing element is slightly abraded, the gluing mechanism can work normally; besides, only the O-shaped sealing ring needs to be replaced while a high-temperature bearing is not required to be replaced during maintenance, so that the maintaining cost is low; with the leakage-proof device, the problems that a traditional gluing device frequently suffers from bearing locking and maintaining trouble and the like are effectively solved.

Description

technical field [0001] The invention relates to the technology in the field of woodworking machinery, in particular to an anti-leakage device for a gluing mechanism of an edge banding machine that prevents the locking of the gluing shaft and has a good leak-proof effect. Background technique [0002] At present, when the gluing device of the edge banding machine in the domestic and foreign markets is working, the high-temperature glue in the glue supply box is driven by the rotation of the gluing shaft to lift, so that the glue is evenly covered on the surface of the working part of the gluing shaft to achieve gluing. Features. Since the gluing shaft has been doing relative rotary motion in a high-temperature environment, it is easy to cause poor sealing of the gluing mechanism. Therefore, on the one hand, it is easy to cause glue to flow into the bearing, and cause the bearing to lock after the glue cools and solidifies, resulting in glue coating on the edge. Mechanism can...

Problems solved by technology

[0003] In the prior art, the slender gap between the rotating shaft and the glue supply box and the graphite bearing are generally used for sealing, but this sealing effect is not good, and the glue easily enters the inside of the bearing, and the glue entering the inside of the bearing is prone to bearing lockup Defective phenomenon, resulting in shorter life of the bearing, usually need to replace the bearing during maintenance, resulting in higher maintenance and use costs
