Description

Technical Field

[0001] This utility model relates to the field of glue applicator technology, and in particular to a multi-channel glue dispensing device for an adjustable width glue applicator. Background Technology

[0002] In modern industrial production, glue applicators are important processing equipment widely used in many fields such as electronics, packaging, and furniture manufacturing. With the increasing diversification and sophistication of production demands, higher requirements are being placed on the performance of the glue dispensing device of the glue applicator.

[0003] Traditional glue applicators often suffer from inconvenient glue width adjustment. Most glue dispensing devices have a fixed glue width or only allow for limited adjustments, making it difficult to meet the glue application requirements of different sizes and processes. For example, glue application of electronic components requires narrow and precise glue application, while glue application of packaging materials requires wide and large-area glue application. Traditional devices cannot efficiently switch between different scenarios, limiting the applicability of glue applicators.

[0004] Traditional dispensing valves are complex to install and maintain. Installation and disassembly typically require multiple tools, consuming significant time and manpower. This not only increases equipment maintenance costs but also reduces equipment efficiency, making it difficult to quickly respond to the need for valve replacement or adjustment for different dispensing tasks.

[0005] An unstable dispensing valve is also a common problem. Due to the lack of effective fixing measures, the dispensing valve is prone to displacement during the glue application process, leading to uneven glue application, misalignment, and other quality problems, which seriously affect the glue application effect and production quality of the product.

[0006] Furthermore, traditional multi-channel glue dispensing devices for glue applicators have shortcomings in glue delivery. It is difficult to deliver the glue evenly and stably to each dispensing valve, easily leading to insufficient or excessive glue supply to some valves. This results in inconsistent glue thickness and quality, reducing the yield rate of glued products and failing to meet the requirements of high-precision glue application processes.

[0007] Therefore, how to provide a multi-channel glue dispensing device for an adjustable width glue applicator is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] One objective of this invention is to provide a multi-channel glue dispensing device for an adjustable-width glue applicator. This invention allows for free adjustment of the glue application width by flexibly increasing or decreasing the number of glue dispensing valves and adjusting their positions, thus meeting the diverse production needs for both narrow-width fine glue application and wide-width large-area glue application. Furthermore, the installation structure, which utilizes a combination of movable rods, buckles, and springs, simplifies the installation and disassembly process of the glue dispensing valves, reduces equipment maintenance costs, and improves efficiency.

[0009] According to an embodiment of the present invention, an adjustable width glue applicator with multiple channels includes a mounting frame, glue dispensing valves, and a conveying pipe. A support frame is fixedly installed on the inner front end of the mounting frame, and a mounting hole is opened through the support frame. The number of glue dispensing valves is multiple, and the multiple sets of glue dispensing valves are inserted into the mounting holes. A mounting seat is provided on the top of each glue dispensing valve. The mounting seat is larger than the mounting hole and is placed above the support frame. The conveying pipe is horizontally fixedly installed on the rear side of the top of the mounting frame.

[0010] Furthermore, the mounting base has symmetrical through holes on both sides inside, and a movable rod is installed through the through holes. A buckle is fixedly installed at the end of the movable rod and at the rear side of the mounting base. A pressing plate is fixedly installed at the front end of the movable rod. The mounting base is fixedly connected to the support frame through the buckle.

[0011] Furthermore, a clamping seat is provided at the bottom front end of the mounting base, and a screw hole is provided through the clamping seat. A screw is screwed into the screw hole, and the screw can be rotated through the screw hole and then abut against the outer wall of the support frame.

[0012] Furthermore, a spring is fitted in front of the mounting base and onto the two sets of movable rods, with both ends of the spring being fixedly connected to the mounting base and the pressing plate, respectively.

[0013] Furthermore, the bottom of the dispensing valve is provided with a dispensing nozzle, and the top of the dispensing valve is provided with an interface, which is connected to the feed end of the dispensing valve.

[0014] Furthermore, multiple sets of connectors are equidistantly arranged at the top of the conveying pipe, and the connectors can be connected to the interface via flexible hoses.

[0015] Furthermore, the side wall of the conveying pipe is provided with a feed inlet.

[0016] Furthermore, the movable rod and the through hole are fitted with a clearance, allowing the movable rod to move flexibly within the through hole.

[0017] Furthermore, the thread fit between the screw and the screw hole is accurate enough to ensure that the screw can be firmly pressed against the outer wall of the support frame after being tightened.

[0018] Furthermore, the dispensing nozzle at the bottom of the dispensing valve has a flat structure.

[0019] The beneficial effects of this utility model are:

[0020] 1. In this utility model, multiple sets of glue dispensing valves are inserted into the mounting holes of the support frame.

[0034] Example 1

[0035] like Figures 1-4As shown, this utility model discloses a multi-channel glue dispensing device for an adjustable width glue applicator, including a mounting frame 1, glue dispensing valves 8, and a conveying pipe 3. A support frame 2 is fixedly installed on the inner front end of the mounting frame 1, and a mounting hole 6 is provided through the support frame 2. Multiple sets of glue dispensing valves 8 are inserted and installed in the mounting holes 6. A mounting seat 7 is provided on the top of the glue dispensing valve 8. The mounting seat 7 is larger than the mounting hole 6 and is positioned above the support frame 2. The conveying pipe 3 is horizontally fixedly installed on the rear side of the top of the mounting frame 1.

[0036] The specific working process is as follows: First, fix the mounting bracket 1 in the corresponding position on the glue applicator. Then, input the glue into the feed pipe 3 through the feed port 5 on the side wall of the feed pipe 3. Multiple sets of connectors 4, evenly spaced at the top of the feed pipe 3, are connected to the interface 9 on the top of the glue outlet valve 8 via flexible hoses, allowing the glue to be delivered to each glue outlet valve 8. The flat glue applicator nozzle 18 at the bottom of the glue outlet valve 8 is used to apply the glue to the object to be glued.

[0037] In this embodiment, when it is necessary to adjust the adhesive application width, this can be achieved by adjusting the number and position of the adhesive dispensing valves 8. For example, increasing or decreasing the number of adhesive dispensing valves 8, or adjusting the position of the adhesive dispensing valves 8 within the mounting hole 6, will change the adhesive application width.

[0038] Example 2

[0039] Based on Embodiment 1, the mounting base 7 has symmetrical through holes 11 on both sides inside. A movable rod 12 is installed through the through hole 11, and the movable rod 12 is clearance-fitted with the through hole 11, allowing the movable rod 12 to move flexibly within the through hole 11. A buckle 10 is fixedly installed at the end of the movable rod 12 and on the rear side of the mounting base 7, and a pressing plate 14 is fixedly installed at the front end of the movable rod 12. A spring 13 is sleeved on the front of the mounting base 7 and on the two sets of movable rods 12. The two ends of the spring 13 are fixedly connected to the mounting base 7 and the pressing plate 14, respectively. The mounting base 7 is fixedly connected to the support frame 2 through the buckle 10.

[0040] In this embodiment, when it is necessary to install or remove the dispensing valve 8, press the pressing plate 14 to move the movable rod 12 forward within the through hole 11, causing the buckle 10 to disengage from the support frame 2. At this time, the dispensing valve 8 can be removed from or inserted into the mounting hole 6. Release the pressing plate 14, and under the action of the spring 13, the movable rod 12 moves backward, and the buckle 10 re-engages with the support frame 2, thus fixing the dispensing valve 8.

[0041] Example 3

Multiple sets of connectors 4 evenly spaced at the top of the conveying pipe 3 can be connected to the interface 9 via flexible hoses, enabling accurate delivery of the adhesive to each dispensing valve 8 and ensuring the stability and consistency of multi-channel dispensing.

[0045] As a preferred example of this application, the number of dispensing valves 8 can be adjusted according to the actual glue application width requirements, for example, by setting 3, 5, or more groups. This allows for flexible and convenient adjustment of the processing status, greatly improving the equipment's operational flexibility.

[0046] As a preferred example of this application, the inlet 5 of the conveying pipe 3 can be connected to different rubber supply devices to accommodate different types of rubber.

[0047] As a preferred example of this application, the hose can be made of a high-pressure resistant and corrosion-resistant material to ensure the safe and stable delivery of the adhesive.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
