Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal processing line glue application device. Background Technology

[0002] CFRT thermoplastic composite panels are commonly used in commercial vehicle body panels. These panels consist of a central interlayer with skins glued to both sides. After gluing, they undergo pressing and other processes. Traditionally, this involves manual application of adhesive, which is inefficient and prone to uneven application. While spray-applied adhesive devices have emerged, traditional nozzles tend to clog after a period of use, affecting future use. Therefore, there is an urgent need for an automated and clog-resistant adhesive application device. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a glue application device for a sheet metal processing line.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a glue-applying device for a sheet metal processing line, comprising a horizontal slide rail and an L-shaped movable bracket disposed on the front side of the slide rail, with the horizontal end of the L-shaped movable bracket facing upwards. A guide slider located within a slide rail groove is disposed on the side wall of the vertical portion. A glue-applying head is disposed at the bottom of the outer side wall of the L-shaped movable bracket. The bottom two sides of the glue-applying head are inclined, making the bottom center width smaller than the top width. A glue-applying nozzle with multiple spray holes is disposed at the bottom center of the glue-applying head. Glue-applying valves are respectively disposed on both sides of the upper surface of the glue-applying head, and the glue outlet end of the glue-applying valve is provided with a positioning... The glue spraying chamber inside the glue spraying nozzle has cleaning pipe connectors on the left and right sides of the front of the glue spraying head. The spraying channels of the cleaning pipe connectors are connected to the corresponding glue spraying chambers. The bottom of each glue spraying chamber is connected to the glue spraying nozzle through the glue spraying channel. The spraying channel of the cleaning pipe connector inside the glue spraying chamber is covered by a rubber sealing plate, and one end of the rubber sealing plate is fixedly attached to the side wall of the glue spraying chamber. The glue spraying pipe connected to the glue spraying valve and the water pipe connected to the cleaning pipe connector are connected to the external equipment through the drag chain structure fixed at the top of the L-shaped movable bracket. The L-shaped movable bracket is driven by the drive structure to slide left and right on the slide rail.

[0005] Furthermore, the upper end of the rubber sealing plate is fixedly connected to the side wall of the adhesive spraying chamber, and the rubber sealing plate gradually narrows from top to bottom.

[0006] Furthermore, the L-shaped movable bracket above the glue spraying head is equipped with a drive wheel driven by a reduction motor. The inner side of the drive wheel passes through the opening of the L-shaped movable bracket and contacts the front side of the slide rail.

[0007] Furthermore, the glue spraying head is slidably set at the bottom of the outer wall of the L-shaped movable bracket, and a vertical cylinder rod is fixed on the upper surface of each side glue spraying valve. The cylinder rods on each side are driven to rise and fall by the cylinders on the left and right sides of the front of the L-shaped movable bracket.

[0008] Furthermore, a cable chain tray for placing cable chains is fixed to the top rear side of the slide rail.

[0009] Furthermore, the inner diameter of the glue spraying chamber is larger than the inner diameter of the spraying channel and the glue spraying channel.

[0010] Furthermore, the horizontal end of the L-shaped movable bracket is provided with multiple elongated adjustment openings, which are used to fix the cable chain by bolts and nuts.

[0011] With the above settings, when the machine needs to be stopped, the glue spraying valve closes. At this time, clean water is sprayed out through the external clean water tank, water pump, clean water pipe, and cleaning pipe connector. Since the rubber sealing plate firmly covers the outlet of the spraying channel from top to bottom, the rubber sealing plate can press the outlet of the spraying channel during glue spraying to prevent the glue from flowing back into the clean water pipe. When injecting clean water, the rubber sealing plate can be better flushed open from the bottom to the top, and the glue spraying valve outlet, glue spraying chamber, glue spraying channel, and glue spraying nozzle can be thoroughly cleaned. The cleaning is more comprehensive and thorough, effectively preventing glue residue in the glue spraying structure and preventing the glue spraying head and nozzle from becoming viscous and dry due to glue standing during shutdown, thus preventing blockage. It also facilitates automated cleaning and easy reuse in the future. Attached Figure Description

[0014] Figure 2 This is a three-dimensional structural diagram of the present invention in use. Detailed Implementation

[0015] like Figure 1-2As shown, a glue-applying device for a sheet metal processing line includes a horizontal slide rail 1 and an L-shaped movable support 2 located in front of the slide rail 1, with the horizontal end of the L-shaped movable support 2 facing upwards. A guide slider located within a groove in the slide rail 1 is provided on the side wall of the vertical portion. A glue-applying head 3 is provided at the bottom of the outer side wall of the L-shaped movable support 2. The bottom sides of the glue-applying head 3 are sloped, making the bottom center width smaller than the top width. A glue-applying nozzle 4 with multiple spray holes is provided at the bottom center of the glue-applying head 3. Glue-applying valves 5 are respectively provided on both sides of the upper surface of the glue-applying head 3. The glue outlet of the glue-applying valve 5 is provided with a glue-applying chamber 6 located within the glue-applying nozzle 4. Cleaning pipe connectors 7 are respectively provided on the left and right sides of the front side of the glue-applying head 3. The spray channels of the cleaning pipe connectors 7 are connected to the corresponding glue-applying chambers 6. The bottom of each side spraying chamber 6 is connected to the spraying nozzle 4 through the spraying channel 8. The spraying channel of the cleaning pipe connector 7 inside the spraying chamber 6 is covered by a rubber sealing plate 9, and one end of the rubber sealing plate 9 is fixedly attached to the side wall of the spraying chamber 6. The upper end of the rubber sealing plate 9 is fixedly connected to the side wall of the spraying chamber 6, and the rubber sealing plate 9 gradually narrows from top to bottom. In this way, when water is injected, the rubber sealing plate 9 can be better flushed open from bottom to top. When applying glue, the rubber sealing plate 9 firmly covers the outlet of the spraying channel from top to bottom to prevent the glue from flowing back into the water pipe. The inner diameter of the spraying chamber 6 is larger than the inner diameter of the spraying channel and the spraying channel 8. In this way, when water enters the spraying chamber 6, it can form a flow from bottom to top and then from top to bottom.

[0016] The glue spraying pipe connected to the glue spraying valve 5 and the water pipe connected to the cleaning pipe connector 7 are respectively connected to the external equipment through the drag chain structure fixed at the top of the L-shaped movable bracket 2. The L-shaped movable bracket 2 is driven by the drive structure to slide left and right on the slide rail 1.

[0017] The L-shaped movable bracket 2 above the glue spraying head 3 is equipped with a drive wheel 11 driven by a reduction motor 10. The inner side of the drive wheel 11 passes through the opening of the L-shaped movable bracket 2 and contacts the front side of the slide rail 1. In order to facilitate the adjustment of the height of the glue spraying head 3, the glue spraying head 3 is slidably set at the bottom of the outer wall of the L-shaped movable bracket 2. A vertical cylinder rod 12 is fixed on the upper surface of each side glue spraying valve 5. The cylinder rod 12 on each side is driven to rise and fall by the cylinders 13 on the left and right sides of the front of the L-shaped movable bracket 2, that is, like the current slide cylinder, which can drive the glue spraying head 3 to move up and down to adjust the height.

[0018] To facilitate the fixing of the cable chain and thus the routing of lines such as glue spraying hoses, water pipes, and wires, a cable chain support plate 14 for placing the cable chain is fixed to the top rear side of the slide rail 1, and multiple elongated adjustment openings are provided at the horizontal end of the L-shaped movable bracket 2. The adjustment openings are used to fix the cable chain by bolts and nuts.

[0019] The working principle of this utility model is as follows: The glue application process of this utility model is the same as the existing reciprocating spray glue application method. Both are driven by a drive structure to move back and forth. For example, this utility model uses a geared motor 10 to drive the drive wheel 11 to move back and forth. During the back and forth movement, the glue is collected through the glue spray valves 5 opened on both sides and the glue spray channel 8 to the glue spray nozzle 4, and finally sprayed out from the glue spray nozzle 4. With the L-shaped movable bracket 2, the glue is sprayed back and forth. In addition, during the glue application process, with the current conveying equipment, such as the conveyor belt, moving forward, the glue is sprayed on the entire board surface in an S-shaped meandering manner.

[0020] When the machine needs to be stopped, the glue spraying valve 5 is closed. At this time, clean water is sprayed out through the external clean water tank, water pump, clean water pipe and cleaning pipe connector 7. Since the rubber sealing plate 9 firmly covers the outlet of the spraying channel from top to bottom, the rubber sealing plate 9 can be pressed down on the outlet of the spraying channel during glue spraying to prevent glue from flowing back into the clean water pipe. When injecting clean water, the rubber sealing plate 9 can be better flushed open from bottom to top, and the outlet of the glue spraying valve 5, the glue spraying chamber 6, the glue spraying channel 8 and the glue spraying nozzle 4 can be thoroughly cleaned to prevent glue residue, effectively prevent the glue spraying head 3 and the glue spraying nozzle 4 from clogging, and facilitate automated cleaning and reuse in the future.

[0021] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
