Description

Technical Field

[0001] This utility model specifically relates to a metal sheet surface polishing device. Background Technology

[0002] Metal sheets, with their high strength and stability, are widely used in many industries such as machinery manufacturing, building decoration, and automotive parts processing. Surface polishing of metal sheets, as a key process for improving their appearance and performance, directly affects the assembly precision, corrosion resistance, and market competitiveness of subsequent products.

[0003] During the polishing process, polishing agents are sprayed onto the surface of metal sheets. For example, Chinese invention patent CN105150107A provides a polishing machine that pre-sprays polishing agents onto sheets. This polishing machine can pre-spray polishing agents onto the sheets before polishing, which greatly improves the polishing quality and efficiency, makes the polishing process smoother, makes the sheets smoother, and improves product quality.

[0004] However, the spraying components of existing devices have limited spraying range due to the fixed nozzles, which can easily create blind spots on the surface of the board. This results in some areas not being covered with polishing agent, leading to excessive wear and increased surface scratches in the uncovered areas during polishing due to lack of lubrication and abrasive media, which seriously affects the polishing effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model proposes a metal sheet surface polishing device to solve the technical problem mentioned in the background art that most existing metal sheet surface polishing devices directly spray polishing agent onto the sheet, which will result in uneven spraying of polishing agent and a decrease in polishing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal sheet surface polishing device, comprising: A roller conveyor is provided with a frame, on which spray pipes are provided, and multiple sets of spray nozzles are provided at intervals on the spray pipes; A mounting shaft is rotatably mounted on the frame, and a drive mechanism connected to the mounting shaft is provided on the roller conveyor. This drive mechanism converts the rotation of the rollers on the roller conveyor into driving the rotation of the mounting shaft. An installation cylinder is slidably sleeved on the installation shaft along its axis, and an application roller is sleeved on it. The installation shaft and the installation cylinder are connected by a linkage mechanism, which converts the rotation of the installation shaft into driving the installation cylinder to slide back and forth.

[0007] In a preferred embodiment, the roller conveyor sidewall is provided with a mounting ring, the mounting ring is rotatably provided with a mounting arm, the end of the mounting shaft is rotatably provided on the mounting arm, and a telescopic rod is hinged to the roller conveyor, one end of the telescopic rod being hinged to the mounting arm.

[0008] In a preferred embodiment, the frame is provided with an arc-shaped track, and the end of the mounting shaft is provided with a limiting wheel, which is slidably engaged within the arc-shaped track.

[0009] In a preferred embodiment, the drive mechanism includes: A first synchronizing pulley is disposed at the end of one set of rollers of the roller conveyor; and The second synchronous pulley is located at the end of the mounting shaft and is connected to the first synchronous pulley via a synchronous belt.

[0010] In a preferred embodiment, the linkage mechanism includes: Drive column, disposed on the circumferential side of the mounting shaft; and A guide cylinder is fixedly mounted on the mounting arm. Multiple sets of guide rails are provided inside the guide cylinder. The ends of the multiple sets of guide rails are connected by inclined rails. The drive column is slidably engaged in the guide rails.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In use, the polishing machine is mounted on a roller conveyor. The conveyor transports the sheet metal, which is then polished as it passes through the polishing machine. Polishing agent is sprayed onto the sheet metal through a nozzle. A drive mechanism converts the rotation of the rollers on the conveyor into the rotation of the mounting shaft. As the mounting shaft rotates, it drives the mounting cylinder to rotate, thus spreading the polishing agent onto the sheet metal through the application roller. A linkage mechanism further converts the rotation of the mounting shaft into the reciprocating sliding of the mounting cylinder, ensuring that the polishing agent is evenly applied to the sheet metal and preventing areas from lacking polishing agent, effectively improving the subsequent polishing effect.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0015] Example: like Figure 1 , 2 As shown, this utility model provides a metal sheet surface polishing device, including a roller conveyor 1, a frame 2 mounted on the roller conveyor 1, a spray pipe 3 mounted on the frame 2, and multiple sets of nozzles 4 spaced apart on the spray pipe 3. In use, a polishing machine (not shown) can be installed on the roller conveyor 1. The spray pipe 3 is connected to a polishing agent supply device outside the pump body. The plate is conveyed by the rotation of the rollers on the roller conveyor 1. When the plate passes through the frame 2, the polishing agent can be sprayed onto the plate through the nozzles 4, and then the plate passes through the polishing machine to improve the polishing effect.

[0016] like Figures 1 to 4 As shown, in this embodiment, a mounting shaft 13 is rotatably mounted on the frame 2. A mounting cylinder 17 is slidably sleeved on the mounting shaft 13 along its axis. An applicator roller 18 is sleeved on the mounting cylinder 17. A mounting ring 6 is provided on the side wall of the roller conveyor 1. A mounting arm 7 is rotatably mounted on the mounting ring 6. The end of the mounting shaft 13 is rotatably mounted on the mounting arm 7. A telescopic rod 11 is hinged to the roller conveyor 1, with one end of the telescopic rod 11 hinged to the mounting arm 7. An arc-shaped track 12 is provided on the frame 2. A limit wheel 14 is provided at the end of the mounting shaft 13, and the limit wheel 14 is slidably engaged within the arc-shaped track 12.

[0017] The extension and retraction of the telescopic rod 11 can drive the mounting arm 7 to rotate along the axis of the mounting ring 6, thereby driving the mounting shaft 13 to move. The height of the application roller 18 can be adjusted by the mounting shaft 13, allowing the application roller 18 to contact materials of different thicknesses, facilitating the subsequent even application of polishing agent. The movement of the mounting shaft 13 is limited by the cooperation of the arc-shaped track 12 and the limiting wheel 14, improving the stability of the device structure.

[0018] like Figure 1 , 2 As shown in Figure 4, in this embodiment, the roller conveyor 1 is provided with a drive mechanism connected to the mounting shaft 13. The drive mechanism converts the rotation of the rollers on the roller conveyor 1 into the rotation of the mounting shaft 13. The drive mechanism includes a first synchronous wheel 5 provided at the end of one set of rollers on the roller conveyor 1, and a second synchronous wheel 15 provided at the end of the mounting shaft 13. The second synchronous wheel 15 and the first synchronous wheel 5 are connected by a synchronous belt 16.

[0019] During operation, the rollers installed on the roller conveyor 1 rotate to transport the sheet material and drive the first synchronous wheel 5 to rotate. During the rotation of the first synchronous wheel 5, the installation shaft 13 can be controlled to rotate through the cooperation of the synchronous belt 16 and the second synchronous wheel 15. During the rotation of the installation shaft 13, the polishing agent sprayed on the surface of the sheet material can be evenly spread by the application roller 18.

[0020] like Figure 1 , 3 As shown in Figure 4, in this embodiment, the mounting shaft 13 and the mounting cylinder 17 are connected by a linkage mechanism, which converts the rotation of the mounting shaft 13 into the reciprocating sliding of the mounting cylinder 17. The linkage mechanism includes a drive column 19 disposed around the mounting shaft 13, a guide cylinder 8 fixedly disposed on the mounting arm 7, and multiple sets of guide rails 9 disposed inside the guide cylinder 8. The ends of the multiple sets of guide rails 9 are connected by inclined rails 10, and the drive column 19 is slidably engaged within the guide rails 9.

[0021] The mounting shaft 13 and the mounting arm 7 rotate relative to each other. During the rotation, the drive column 19 of the mounting shaft 13 slides in the guide rail 9 and drives the mounting cylinder 17 to slide back and forth along the axis of the mounting shaft 13 through the inclined rail 10, thereby evenly applying the polishing agent to the surface of the board and further improving the polishing effect.

[0022] The specific usage and beneficial effects of this utility model are as follows: In use, the polishing machine is mounted on the roller conveyor 1. The roller conveyor 1 transports the sheet metal, which is then polished as it passes through the polishing machine. Polishing agent is sprayed onto the sheet metal through the nozzle 4. The rotation of the rollers on the roller conveyor 1 is converted into the rotation of the mounting shaft 13 by the drive mechanism. During the rotation of the mounting shaft 13, the mounting cylinder 17 rotates, so that the polishing agent is applied to the sheet metal through the application roller 18. The rotation of the mounting shaft 13 is converted into the reciprocating sliding of the mounting cylinder 17 by the linkage mechanism, so that the polishing agent is evenly applied to the sheet metal, avoiding areas where the polishing agent is not adhered, and effectively improving the subsequent polishing effect.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
