Glue Applying Mechanism with Rotatable Regulator for Edge Banding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional edge banding machines lack the ability to effectively adjust glue quantity for different workpiece specifications and types of glue, necessitating a mechanism to regulate glue application accurately.
Innovation Solution
A glue applying mechanism with a rotatable glue quantity regulator, comprising a base, a glue applying unit with a tapered glue applying surface, and a rotatable shaft with a regulating plate, allowing operators to adjust the gap between the regulator and the glue applying unit to control the glue thickness applied to the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed glue applying mechanism is used, then the structure is simple, but the glue quantity cannot be adjusted for different workpiece specifications and glue types
Solution Approach 1:
The patent applies the dynamics principle by making the regulating plate rotatable around the glue shaft. This allows the gap between the regulating plate and the tapered surface to be dynamically adjusted, enabling variable glue quantity control. The rotatable mechanism transforms a static structure into a dynamic one, providing adaptability for different workpiece specifications and glue types without significantly complicating the overall device structure.
2Productivity
If the glue applying surface is made tapered, then glue extraction efficiency is improved, but controlling the glue thickness becomes more difficult
Solution Approach 1:
The patent uses the regulating plate as an intermediary element between the glue shaft and the glue application area. The regulating plate with its vertical edge and oblique edge creates a controlled gap that mediates the glue flow from the tapered surface. This intermediary structure allows the tapered surface to maintain its high extraction efficiency while the regulating plate precisely controls the glue thickness by adjusting the gap distance, thus resolving the contradiction between extraction efficiency and thickness control.

AI summary
A glue applying mechanism of an edge banding machine includes a base, a glue applying unit and a glue quantity regulator. The base includes a glue tub. The glue applying unit is rotatably disposed on the glue tub of the base and includes a glue shaft and an obliquely glue applying member connected with the glue shaft. The glue quantity regulator is rotatably disposed on the base and includes a rotatable shaft, and a regulating plate and a blocking plate, which are connected with the rotatable shaft. The regulating plate is rotatable along with the rotatable shaft to cause edges of the regulating plate adjacent to the glue applying unit at the same time. The blocking plate is fixed to the rotatable shaft separately from the regulating plate. The above-described configuration of the glue applying mechanism is effective in controlling the applied glue quantity in thickness.
