Description

Technical Field

[0001] This utility model relates to a glue applicator, and more particularly to a combined glue applicator with double rows of holes. Background Technology

[0002] Color-coated steel sheet, also known as pre-painted steel sheet, is a type of steel sheet with an organic coating. Color-coated steel sheets are categorized into single-layer sheets, composite sheets, and floor decking, among others. The current processing of composite sheets involves applying adhesive to the face panel first, then bonding the face panel and the base panel together.

[0003] In the existing technology, when applying adhesive to the panel of a color steel composite panel, an adhesive applicator is required. However, existing adhesive applicators apply adhesive in a single pass, which can lead to uneven adhesive application and affect the production quality of the composite panel. Utility Model Content

[0033] Please see Figure 1-4 This utility model provides a combined glue applicator with dual-row nozzles, comprising:

[0034] The sandwich panel 1 has at least one glue inlet hole 2 and at least one layer of branched flow channels 3 on each side. Adjacent branched flow channels 3 are interconnected. The uppermost branched flow channel 3 is connected to the glue inlet hole 2, and the lowermost branched flow channel 3 is connected to the glue outlet hole 4 on the sandwich panel 1. Specifically, the upper branched flow channel splits downward into two branched flow channels, and then splits downward into two or three branched flow channels, and so on, to achieve the purpose of uniformly distributing glue.

[0035] A clamping plate 5 is detachably connected to each side of the sandwich panel 1, and the clamping plate 5 seals and covers the bifurcation channel 3.

[0036] The sandwich panel 1 is provided with a connecting channel 6. The upper side of the connecting channel 6 is connected to the bottommost branched channel 3, and the lower side of the connecting channel 6 is connected to several glue outlet holes 4. The glue outlet holes do not need to correspond one-to-one with the outlets of the branched channels, thus multiple glue outlet holes can be provided, making the glue application more uniform.

[0037] The glue outlet holes 4 on both sides of the sandwich panel 1 are arranged in parallel and correspond to each other. This allows for two glue application processes in the same area of ​​the panel, preventing glue leakage caused by blockage of the glue outlet holes on one side.

[0038] The glue outlet holes 4 on both sides of the sandwich panel 1 are staggered, which allows for more uniform glue application to the panel.

[0039] The sandwich panel 1 is provided with at least two first screw holes 7, and the clamping plate is provided with second screw holes 8 corresponding to the positions of the first screw holes. Locking screws are inserted into the first screw holes 7 and the second screw holes 8. This facilitates the disassembly and assembly of the clamping plate, thereby making it easier to clean the branched flow channel.

[0040] The corners of the branched flow channel 3 are rounded. This reduces adhesive buildup in the branched flow channel. The adhesive outlet and inlet are also circular.

[0041] Working principle: During use, the glue is injected through the inlet hole and then enters the branched flow channel. The branched flow channel is arranged in multiple layers to ensure that the glue travels a similar distance to each hole, resulting in the same amount of glue sprayed from the outlet hole. By setting up dual outlet holes, the front outlet hole sprays glue once, and the rear outlet hole sprays glue again, achieving double glue spraying, preventing glue leakage in some areas of the panel, and improving the glue spraying quality of the panel. The multi-layered arrangement of the branched flow channel can achieve the purpose of uniform glue distribution, making the glue spraying on the panel uniform.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
