Description

Technical Field

[0001] This utility model relates to the field of edge banding manufacturing technology, specifically to a miniature edge banding adhesive applicator. Background Technology

[0002] Edge banding is mainly used for edge banding of furniture boards. After being extruded from the injection molding machine, it needs to be coated with glue after embossing and shaping. The purpose of the glue coating is to facilitate good adhesion and sealing with the board later. However, traditional edge banding adhesive application methods employ open traction and manual application. Specialized traction equipment is used to pull a specific type of edge banding, and manual application of adhesive is performed, with the length of adhesive application measured manually in real time. This method is not only inconvenient and unsafe in terms of loading, unloading, and application, but also fails to guarantee the thickness and uniformity of the adhesive, resulting in a high defect rate. This severely impacts the efficiency and quality of adhesive application and increases worker fatigue. Furthermore, traditional methods can only apply adhesive to one type of edge banding at a time, failing to meet the needs of large-volume, multi-type edge banding applications, hindering overall production cost control. Additionally, adhesive is prone to seepage during manual application, leading to low adhesive utilization and significant waste, and negatively impacting workplace cleanliness and hygiene. Furthermore, edge banding strips are generally quite long, and traditional glue containers have limited capacity. Too much glue cannot be added at once, requiring regular checks to ensure the glue level is within the normal range. If operators forget to check the remaining glue in the container, the glue application may suddenly stop after a certain distance, hindering continuous application and causing discrepancies in the final application. This necessitates frequent rework, severely impacting the overall quality and efficiency of the edge banding application.

[0003] In conclusion, it is necessary to further improve the existing technology. Summary of the Invention

[0022] The advantages of this utility model are mainly reflected in the following aspects:

[0023] (1) The glue application assembly and the traction assembly are integrated into one machine and driven by the same drive motor. The machine has low manufacturing cost. The traction and glue application operations of the edge banding are controlled by the electronic control unit. It is not only easy to operate, but also significantly improves the glue application efficiency of the edge banding.

[0025] (3) The height of the upper traction wheel can be adjusted in real time through the upper traction wheel height adjustment component, which greatly facilitates the loading and unloading of the edge banding strip and can also realize the traction of edge banding strips of different thicknesses; the height of the glue coating roller can be adjusted through the glue coating roller lifting adjustment component, which facilitates the loading and unloading of the edge banding strip and the glue coating of edge banding strips of different thicknesses; the glue coating roller scraping component can scrape off excess glue on the outer roller surface of the glue coating roller in a timely manner, so that the outer roller surface of the glue coating roller always retains the best glue thickness to uniformly coat the edge banding strip, which significantly improves the glue coating effect and quality of the edge banding strip and greatly reduces the product rework rate.

When the meter counter detects the preset edge banding strip length, the normally open contact of the second relay closes, the meter counter alarm 12 is powered on and starts, emitting an audible and visual alarm to remind the worker to cut the edge banding strip.

[0054] The power input terminal of the intermediate relay is connected to the power output terminal of the emergency stop switch; the normally open contact of the low liquid level float switch is connected in series to the coil circuit of the intermediate relay; when the liquid level is lower than the set value, the low liquid level float switch closes, and the coil of the intermediate relay is energized; the input terminal of the glue level alarm 314 is connected in parallel with the normally open contact of the intermediate relay; when the low liquid level float switch is triggered, the intermediate relay operates, its contacts close, connects the power supply of the glue level alarm 314, and emits an audible and visual signal; the low liquid level float switch achieves on / off switching through the magnetic induction of the magnet and the reed switch, which has a simple structure and strong anti-interference ability.
