Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying machine technology, and in particular to a spraying component for a spraying machine. Background Technology
[0002] As an important surface treatment equipment in modern industry, spraying machines are widely used in automobile manufacturing, furniture production, electronic product casing processing and other fields. Their core function is to atomize the coating and spray it evenly onto the surface of the workpiece to form a protective layer or decorative layer.
[0003] Currently used spraying machines typically consist of a fixed spray gun array and a feeding system. Parameters such as spray gun spacing and the distance between the spray gun and the workpiece surface are preset during the equipment design phase. However, in industrial production, the size, shape, and spraying area of the products to be sprayed vary significantly. When using current spraying components to spray different products, the following problems arise: 1. Overlapping spraying areas, resulting in low spraying efficiency and paint waste; 2. Missed spraying areas and uneven thickness, affecting the surface quality of the product, requiring manual touch-up spraying later, which is inefficient and incurres high labor costs. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A spraying assembly for a spraying machine includes a base, a frame disposed above the base, and a spray gun position adjustment structure, wherein the frame is connected to the base through the frame position adjustment structure.
[0007] The spray gun position adjustment structure includes a mounting base and several spray gun seats. A mounting base position adjustment component for adjusting the position of the mounting base is installed on the frame. The mounting base is "[" shaped. Two guide rails are fixedly installed on the mounting base. The spray gun seats slide with the guide rails. The lower spray gun seat is fixedly connected to the mounting base. A synchronous movement component for driving other spray gun seats to move synchronously is installed on the mounting base. A spray gun is fixedly installed on the spray gun seat.
[0008] In this way, the base is installed inside the spraying machine. The frame is installed using a frame position adjustment structure, and its position can be adjusted to change the distance between the spray gun and the workpiece surface. The position adjustment component adjusts the mounting base, thereby adjusting the overall position of the spray gun and thus the spraying range. Guide rails provide the mounting foundation and guidance for the spray gun holder. When adjusting the position of the spray gun holder, a synchronous movement component moves the spray gun holder synchronously, achieving synchronized position adjustment of the spray guns. The distance between adjacent spray guns is the same, better ensuring spraying quality. The mounting base is "[" shaped for easy installation of the guide rails.
[0009] Preferably, the mounting base position adjustment assembly includes a vertically arranged screw, which is connected to the frame via a bearing. The upper end of the screw passes through the frame and is fixedly connected to the output shaft of a first servo motor. The first servo motor is fixedly mounted on the frame. A nut is threaded onto the screw and is fixedly connected to the mounting base. The surface of the mounting base facing the frame slides against the frame.
[0010] Preferably, the synchronous movement component includes a vertically arranged lead screw, the lower end of which is connected to the mounting base via a bearing, the upper end of which passes through the mounting base and is fixedly connected to the output shaft of a second servo motor, the second servo motor being fixedly mounted on the mounting base, the uppermost spray gun holder being fixedly mounted with a connecting block having a threaded hole, and the other spray gun holders having clearance holes through the lead screw.
[0011] A pivot pin is rotatably mounted in the middle of the spray gun holder. The uppermost spray gun holder has an upper rotating arm rotatably mounted on the pivot pin, and the lowermost spray gun holder has a lower rotating arm rotatably mounted on the pivot pin. The remaining spray gun holders are rotatably mounted with intermediate rotating arms. The lower rotating arm is rotatably connected to the intermediate rotating arm above it, the intermediate rotating arm on the adjacent spray gun holder, and the upper rotating arm is rotatably connected to the intermediate rotating arm below it.
[0012] Preferably, the frame position adjustment structure includes a base plate fixedly installed at the lower end of the frame, with elongated holes on both sides of the base plate, and two studs fixedly installed on the base plate. The studs are arranged to extend upward through the elongated holes, and nuts for pressing the base plate are threaded onto the studs.
[0013] Preferably, two reinforcing ribs are fixed between the frame and the substrate.
[0014] In summary, the spraying components for this spraying machine have the advantages of being able to adjust the spray gun spacing and the distance between the spray gun and the product, having a simple and reasonable structure, and being easy to use. Attached Figure Description

[0019] like Figure 1-3 As shown, a spraying assembly for a spraying machine includes a base 1, a frame 2 disposed above the base, and a spray gun position adjustment structure, wherein the frame is connected to the base through the frame position adjustment structure.
[0020] The spray gun position adjustment structure includes a mounting base 3 and several spray gun seats 4. A mounting base position adjustment component for adjusting the position of the mounting base is installed on the frame. The mounting base is "[" shaped. Two guide rails 5 are fixedly installed on the mounting base. The spray gun seats slide with the guide rails. The spray gun seats at the lower end are fixedly connected to the mounting base. A synchronous movement component for driving other spray gun seats to move synchronously is installed on the mounting base. A spray gun 6 is fixedly installed on the spray gun seat.
[0021] In this way, the base is installed inside the spraying machine. The frame is installed using a frame position adjustment structure, and its position can be adjusted to change the distance between the spray gun and the workpiece surface. The position adjustment component adjusts the mounting base, thereby adjusting the overall position of the spray gun and thus the spraying range. Guide rails provide the mounting foundation and guidance for the spray gun holder. When adjusting the position of the spray gun holder, a synchronous movement component moves the spray gun holder synchronously, achieving synchronized position adjustment of the spray guns. The distance between adjacent spray guns is the same, better ensuring spraying quality. The mounting base is "[" shaped for easy installation of the guide rails.
[0022] The spraying machine is equipped with a spraying system, which includes a spraying tank containing paint, a supply pipe connected to the spraying tank, and a spray gun connected to the supply pipe. This is an existing device.
[0023] In implementation, the mounting base position adjustment assembly includes a vertically arranged screw 7, which is connected to the frame via a bearing. The upper end of the screw passes through the frame and is fixedly connected to the output shaft of a first servo motor 8, which is fixedly mounted on the frame. A nut 9 is threaded onto the screw and fixedly connected to the mounting base. The surface of the mounting base facing the frame slides against the frame. The first servo motor drives the screw to rotate, which in turn moves the mounting base vertically via the nut block.
[0024] In implementation, the synchronous movement component includes a vertically arranged lead screw 10. The lower end of the lead screw is connected to the mounting base via a bearing, and the upper end of the lead screw passes through the mounting base and is fixedly connected to the output shaft of the second servo motor 11. The second servo motor is fixedly mounted on the mounting base. The uppermost spray gun holder is fixedly mounted with a connecting block having a threaded hole. The lead screw and the connecting block are connected by a thread. The other spray gun holders are provided with clearance holes through the lead screw.
[0025] A pivot pin 12 is rotatably mounted in the middle of the spray gun holder. The uppermost spray gun holder has an upper rotating arm 13 rotatably mounted on the pivot pin. The lowermost spray gun holder has a lower rotating arm 14 rotatably mounted on the pivot pin. The remaining spray gun holders are rotatably mounted with intermediate rotating arms 15. The lower rotating arm is rotatably connected to the intermediate rotating arm above it, the intermediate rotating arm on the adjacent spray gun holder, and the upper rotating arm is rotatably connected to the intermediate rotating arm below it.
[0026] In this way, when adjusting the position of the spray gun, the second servo motor drives the lead screw to rotate. The lead screw engages with the threaded hole of the uppermost spray gun holder, causing the uppermost spray gun holder to move under the guidance of the guide rod. Through the transmission action of the upper, middle, and lower rotating arms, the spray gun holders move synchronously. The lowermost spray gun holder is fixedly connected to the mounting base. In the synchronous movement assembly, the lengths of the upper and lower rotating arms are half that of the middle rotating arm, forming a linkage structure to achieve synchronous position adjustment.
[0027] In implementation, the frame position adjustment structure includes a base plate 16 fixedly installed at the lower end of the frame. The base plate has elongated holes 17 on both sides. Two studs 18 are fixedly installed on the base, extending upwards through the elongated holes. Nuts 19 for pressing the base plate are threaded onto the studs. Loosening the nuts allows the frame to move relative to the base. Once in position, the nuts press the base plate, fixing the frame's position.
[0028] During implementation, two reinforcing ribs 20 are fixed between the frame and the base plate to improve the installation stability of the frame.
[0029] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
