Description

Technical Field

[0001] This utility model belongs to the field of embossing roller technology, and specifically relates to an embossing roller for making mirror polishing sand belts. Background Technology

[0002] In existing technologies, polishing belts often use materials with good wear resistance and high flexibility, such as polyester film, cotton cloth, or paper, as the substrate. Appropriate abrasive materials, such as alumina and silicon carbide, are selected according to polishing requirements. The abrasive is evenly coated on the substrate surface using methods such as roller coating, scraping coating, or spraying to ensure uniform distribution of the abrasive on the substrate surface and to provide a consistent polishing effect. The coated belt is then sent to a drying chamber or other drying equipment to allow the coating to cure quickly. Depending on the properties of the coating and the manufacturer's process requirements, necessary curing treatments are performed to ensure that the coating adheres firmly to the substrate.

[0003] However, traditional polishing abrasive belts are prone to problems during use, such as the abrasive grains not bonding firmly with the substrate, causing the abrasive grains to fall off and scratch the workpiece to be polished. Traditional polishing abrasive belts are composed of small abrasive grains of uniform size with no gaps between them. If the impurities produced during polishing cannot be released in time, they will accumulate and scratch the workpiece. Therefore, an embossing roller for making mirror polishing abrasive belts is proposed. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an embossing roller for making mirror polishing sandpaper belts, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An embossing roller for producing mirror-polishing abrasive belts includes an embossing roller and a fixed base. The outer surface of the embossing roller is provided with a plurality of square pyramids, and chip removal channels are formed between the plurality of square pyramids. Mounting blocks are fixedly connected to both sides of the embossing roller. Mounting grooves are opened on both sides of one end of the fixed base. The mounting blocks are slidably connected to the mounting grooves. Insertion holes are opened inside the mounting blocks and penetrate one side of the mounting grooves. Insertion rods are inserted into the insertion holes. A power component is provided on one side of the fixed base. A fixing block is provided on the side of the fixed base located on the side of the power component. A positioning component is provided on one side of the fixing block. A drive shaft is fixedly connected to one side of the fixed base.

[0007] As a preferred technical solution, the power assembly includes a transmission rod rotatably connected inside a fixed base. A first toothed cone is fixedly connected to one side of the transmission rod, and a second toothed cone is meshed with one side of the first toothed cone. A screw is fixedly connected to one side of the second toothed cone. The threads on both sides of the screw are arranged in opposite directions. A movable plate is threadedly connected to the outer surface of the screw. A plug is fixedly connected to the movable plate. An adjusting rod is fixedly connected to one side of the transmission rod, and a fixed block is fixedly connected to the adjusting rod.

[0008] As a preferred technical solution, a partition is fixedly connected inside the fixed base, and the screw is rotatably connected to the partition.

[0009] As a preferred technical solution, the positioning component includes a positioning hole, which is formed on the fixing block and extends into the interior of the fixing seat.

[0010] As a preferred technical solution, a guide rod is fixedly connected to one end of the slide plate near the spring, and the guide rod is slidably connected inside the fixed block.

[0011] In summary, the present invention has the following main advantages:

[0012] First, in this utility model, by setting an embossing roller, a four-sided pyramid and a chip removal channel are set on the embossing roller. According to the coarseness of polishing, embossing rollers with different mesh numbers are engraved. The pattern design of the embossing roller adopts three-dimensional dots of a four-sided pyramid, arranged at different angles. Chip removal channels are made at the junction of dots, which can smoothly release polishing impurities and reduce the risk of impurities accumulating and causing scratches on the workpiece. The polishing abrasive belt made by the embossing roller is not easy to fall off and does not easily accumulate polishing impurities, thus improving the success rate of polishing products.

[0013] Secondly, in this utility model, mounting blocks are fixed on both sides of the embossing roller, and a fixed seat is installed on the drive shaft. The mounting blocks are inserted into the mounting groove of the fixed seat, so that the embossing roller is connected to the drive shaft. When the embossing roller needs to be replaced, the positioning component is used to contact the restriction on the fixed block, thereby contacting the restriction on the power component. Then the insertion rod can be moved to move the insertion rod away from the insertion hole, thereby separating the mounting block from the mounting groove. The embossed part of the embossing roller can then be replaced without replacing the whole roller, saving manufacturing costs and facilitating quick disassembly and maintenance.

[0020] Example

[0021] refer to Figures 1 to 5This embodiment describes an embossing roller for producing mirror-polishing abrasive belts, comprising an embossing roller 1 and a fixed base 3. The outer surface of the embossing roller 1 is provided with multiple square pyramids 101, forming chip removal channels 102 between them. Mounting blocks 2 are fixedly connected to both sides of the embossing roller 1. Mounting grooves 4 are formed on both sides of one end of the fixed base 3, and the mounting blocks 2 are slidably connected to the mounting grooves 4. An insertion hole 5 is formed inside the mounting block 2, penetrating one side of the mounting groove 4. An insertion rod 6 is inserted into the insertion hole 5. A power assembly 9 is provided on one side of the fixed base 3. A fixing block 8 is provided on one side of the power component 9 on the fixed seat 3. A positioning component 11 is provided on one side of the fixing block 8. A drive shaft 10 is fixedly connected to one side of the fixed seat 3. The polishing belt is manufactured by embossing a PET substrate coated with UV adhesive using an embossing roller 1 with a grid of four-sided pyramidal dots 101. At the same time, a UV lamp cures the UV adhesive. Then, the PET belt and UV adhesive are peeled off from the embossing roller 1, thus producing a polishing belt. Polishing belts manufactured by this process are not easy to fall off, and the grid of dots on the belt has channels, which makes it difficult for polishing impurities to accumulate, improving the success rate of polishing products. It should be added that, according to the requirements... 1. To determine the surface roughness of the polished workpiece, the designer creates 101-dot matrix structures of different sizes and angles. 2. 3D drawing generation: For rougher workpiece surfaces, a deeper dot matrix structure is needed; for smoother surfaces, a shallower dot matrix structure is required. 3. Dot layering: The designed 3D dot matrix is ​​sliced ​​and layered. For example, to engrave 500µm deep dots, 80-100 layers are needed to ensure the beveled surfaces of the 101-dot matrix are as smooth as possible. 4. Laser engraving: The layered dots are transferred to a direct laser engraving system for multi-layer engraving on a copper-plated steel roller, resulting in the final product. 5. Electrolytic polishing: Place the engraved embossing roller 1 into an electrolytic polishing device for electrolytic polishing to remove the burrs on the surface of the copper roller after laser engraving; 6. Chrome plating: After electrolytic polishing, the roller is chrome-plated to improve the hardness and anti-oxidation function of the embossing roller 1. In specific operation, depending on the roughness of the workpiece surface to be polished, select embossing roller 1 with different mesh counts and depths to make corresponding polishing sandpaper. If a rough surface is required, select embossing roller 1 with larger and deeper dots. If a fine surface is required, select embossing roller 1 with finer and shallower dots. During polishing, change the sandpaper mesh count from coarse to fine to finally achieve a mirror effect on the workpiece.

[0022] refer to Figure 2The power assembly 9 includes a transmission rod 92, which is rotatably connected inside the fixed base 3. A first toothed cone 93 is fixedly connected to one side of the transmission rod 92, and a second toothed cone 94 is meshed with one side of the first toothed cone 93. A screw 95 is fixedly connected to one side of the second toothed cone 94. The threads on both sides of the screw 95 are arranged in opposite directions. A moving plate 96 is threadedly connected to the outer surface of the screw 95. The insertion rod 6 is fixedly connected to the moving plate 96. An adjusting rod 91 is fixedly connected to one side of the transmission rod 92, and a fixing block 8 is fixedly connected to the adjusting rod 91. By setting the power assembly 9, when it is necessary to disassemble the embossing roller 1, the adjusting rod 91 is rotated, which drives the screw 95 to rotate. The screw 95 drives the moving plate 96 to move, and the moving plate 96 drives the insertion rod 6 to move. When the insertion rod 6 leaves the insertion hole 5, the mounting block 2 and the mounting groove 4 are no longer fixed. Then, the embossing roller 1 can be removed from the drive shaft 10 by pulling it.

[0023] refer to Figure 2 The fixed base 3 has a partition 7 fixedly connected inside, and the screw 95 is rotatably connected to the partition 7. By fixing the partition 7 inside the fixed base 3, the sliding distance of the moving plate 96 can be limited, and the moving plate 96 can be prevented from contacting the first tooth cone 93 and the second tooth cone 94.

[0024] refer to Figure 3-4 The positioning component 11 includes a positioning hole 111, which is formed on the fixing block 8 and extends into the interior of the fixing seat 3. A positioning rod 112 is inserted into the positioning hole 111. A sliding plate 115 is slidably connected to the interior of the fixing block 8. A locking block 113 is fixedly connected to one end of the sliding plate 115. A locking groove 114 is formed inside the positioning rod 112. The locking block 113 is movably connected to the locking groove 114. A spring 116 is fixedly connected to the end of the sliding plate 115 away from the locking block 113. The spring 116 is fixedly connected to the interior of the fixing block 8. By setting the positioning component 11, the positioning rod 112 is inserted into the positioning hole 111. At this time, the locking block 113 is connected to the locking groove 114 under the action of the spring 116, so that the positioning rod 112 is fixed to the positioning hole 111. This prevents the fixing block 8 from rotating and restricts the power component 9, making the connection between the embossing roller 1 and the drive shaft 10 more reliable.

[0025] refer to Figure 4 The guide rod 117 is fixedly connected to one end of the slide plate 115 near the spring 116. The guide rod 117 is slidably connected inside the fixed block 8. By setting the guide rod 117 to slide inside the fixed block 8, it is beneficial for the locking block 113 and the locking slot 114 to be accurately connected.

[0026] Operating principle and advantages: The embossing roller 1 is mounted on the drive shaft 10, which is connected to the embossing machine. A four-sided pyramid 101 and a chip removal channel 102 are set on the embossing roller 1. Different mesh sizes of the embossing roller 1 are engraved according to the desired polishing fineness, i.e., different arrangements of the four-sided pyramid 101. Chip removal channels 102 are provided at the junctions of the dots, which can smoothly release polishing impurities, reducing the risk of impurity accumulation causing scratches on the workpiece. It also reduces the accumulation of polishing impurities, improving the success rate of polishing products. When the embossing roller 1 needs to be replaced, the positioning rod 112 is pulled to press the locking block 113 inside the positioning hole 111. The locking block 113 is held in place by the spring 11. Under the action of 6, the slide plate 115 moves, and the slide plate 115 drives the guide rod 117 to move within the fixed block 8, so that the movement of the locking block 113 will not deviate. When the locking block 113 separates from the slot 114, the positioning rod 112 is removed. At this time, the fixed block 8 is no longer restricted, and the adjusting rod 91 can be rotated. Rotating the adjusting rod 91 drives the screw 95 to rotate, and the screw 95 drives the moving plate 96 to move. The moving plate 96 drives the insertion rod 6 to move. When the insertion rod 6 leaves the insertion hole 5, the mounting block 2 and the mounting slot 4 are no longer fixed. Then, the embossing roller 1 can be pulled to remove it from the drive shaft 10 for replacement, which provides convenience for the replacement of the embossing roller 1.
