A leak-proof device for the gluing mechanism of an edge banding machine

Abstract

The invention discloses an anti-leakage device for a glue application mechanism of an edge banding machine, comprising a glue supply box, a glue application shaft, a rubber supply wheel seat, a sealing cover installed between the rubber supply wheel seat and the glue application shaft, and an O-shaped sealing ring , Bearing; Wherein, the gluing shaft includes the gluing shaft working part and the gluing shaft connecting part fixedly connected to each other; the outer wall surface of the gluing shaft working part is provided with a helical lift whose helical direction is opposite to the gluing shaft rotation direction. Groove, the aforementioned sealing cover is used to accept the leaked glue; during the rotation of the glue shaft, the glue is actively lifted up from the receiving groove and the slender gap to the glue supply box by rotating the lifting groove; effectively avoiding the glue from entering In the case of locking inside the bearing, even if the sealing element is slightly worn, the normal operation of the equipment can still be guaranteed, and only the O-ring is replaced during maintenance, and there is no need to replace the high-temperature bearing. The maintenance cost is lower and effective. It solves the problems of bearing locking and maintenance troubles that often occur in traditional gluing devices.

Description

technical field [0001] The invention relates to the technology in the field of woodworking machinery, in particular to an anti-leakage device for the gluing mechanism of an edge banding machine which prevents the gluing shaft from locking 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. Function. 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 the gluing mechanism Can not work norm...

AI Technical Summary

Problems solved by technology

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 the gluing mechanism It cannot work normally, on the other hand, it is very easy for glue to leak onto the workbench, which seriously affects the cleanliness of the workbench and the working environment, and is also a waste of glue

[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
