Description

Technical Field

[0001] This invention belongs to the field of diamond wire manufacturing, and particularly relates to a diamond wire mesh transmission jump limiting device. Background Technology

[0002] Diamond wire, also known as diamond cutting wire, is a special cutting wire made by fixing diamond micropowder to the surface of a metal wire matrix through processes such as electroplating and resin bonding. Its core advantage lies in utilizing the high hardness of diamond to achieve efficient and high-precision cutting of hard and brittle materials such as sapphire, silicon wafers, and silicon carbide. Compared to traditional slurry cutting methods, it has significant advantages such as high cutting efficiency, low material loss, good cut surface smoothness, and environmental friendliness, making it an indispensable key consumable in high-end manufacturing fields such as photovoltaics, semiconductors, and LEDs.

[0003] In the industrial production process of diamond wire, the sand coating process is one of the core links that determines the quality and performance of diamond wire products. This process requires a specific transmission mechanism to achieve continuous and stable transportation of the wire mesh between various process tanks (such as electroplating tanks and cleaning tanks) to ensure that diamond powder can be uniformly and firmly attached to the surface of the metal wire substrate. Currently, the mainstream diamond wire transmission solution in the industry generally adopts a "front and rear double V-groove wire pulley drive" structure. That is, during the operation of the wire mesh, its transmission path is defined and driven by two wire pulleys with V-grooves. The wire mesh is embedded in the V-grooves of the wire pulleys, and the rotation of the wire pulleys drives the wire mesh to move along a preset trajectory, thereby completing the flow in each process tank.

[0004] However, in actual operation, existing transmission equipment based on V-groove reels is prone to vertical fluctuations due to the high-efficiency production requirements of diamond wire manufacturing. This fluctuation, caused by factors such as high-speed inertia, tension fluctuations within the wire itself, and resistance from the liquid in the process tank (e.g., the viscosity of electroplating or cleaning solutions), prevents the wire from accurately embedding into the pre-set position of the V-groove, leading to cross-groove issues. The wire deviates from its assigned V-groove and enters the V-groove of an adjacent reel. Cross-groove wires become entangled and compressed with adjacent wires, resulting in wire breakage. Furthermore, the high-speed wire in this cross-groove state experiences a sharp increase in local tension and uneven stress, ultimately leading to wire breakage. Such wire breakage failures not only directly interrupt the production process, causing wasted time and raw material losses, but may also cause equipment downtime for maintenance due to the wire mesh becoming entangled in equipment parts, further increasing production losses. This seriously restricts the continuity and stability of diamond wire production and makes it difficult to meet the high precision and high reliability requirements of high-end diamond wire manufacturing for transmission systems. Summary of the Invention

[0005] The purpose of this invention is to provide a diamond wire mesh transmission fluctuation limiting device to solve the technical problem in the existing diamond wire production process, where the wire mesh is transmitted at high speed into the wire wheel with V-grooves, and the vertical fluctuation can easily cause cross-grooving and wire breakage, resulting in production interruption and losses.

[0006] To achieve the above objectives, the specific technical solution of the diamond wire mesh transmission jump limiting device of the present invention is as follows:

[0007] A diamond wire mesh transmission jump limiting device includes brackets disposed on both sides of the wire wheel, a rotating shaft connected at both ends to the brackets, a pressure roller rotatably sleeved on the rotating shaft, and a spray structure disposed above the pressure roller;

[0008] The bracket is provided with connecting grooves at both ends of the rotating shaft, and an adjusting block is provided in the connecting groove. The two ends of the rotating shaft are connected to the adjusting block through the shaft hole provided on the adjusting block. The two sides and the bottom of the connecting groove are provided with through adjusting holes. The adjusting component passes through the adjusting hole and enters the connecting groove to abut against the adjusting block.

[0009] The pressing roller comes into contact with the wire mesh from above. The movement of the wire mesh causes the pressing roller to rotate relative to the rotating shaft. The spray structure sprays cooling water onto the pressing roller.

[0010] As a further improvement of the present invention, the spray structure includes a spray interface and a spray pipe. The hollow outer surface of the spray pipe is provided with spray holes facing the pressure roller. Cooling water enters the spray pipe from the spray interface and is sprayed out from the spray holes.

[0011] As a further improvement of the present invention, the spray pipe is connected to the rotating shaft through connecting blocks on both sides. The connecting blocks are provided with an upper connecting hole and a lower connecting hole in the vertical direction. The sides of the connecting blocks are respectively provided with internal threaded holes corresponding to the upper connecting hole and the lower connecting hole. The two ends of the rotating shaft pass through the lower connecting hole and are connected to the adjusting block. The two ends of the spray pipe pass through the upper connecting hole. Bolts pass through the internal threaded holes and abut against the spray pipe and the rotating shaft respectively, fixing the spray pipe above the rotating shaft.

[0012] As a further improvement of the present invention, the pressing roller is sleeved on the rotating shaft by a bearing, the inner ring of the bearing is fixedly connected to the rotating shaft, the outer ring of the bearing is fixedly connected to the inner wall of the pressing roller, and the wire mesh drives the pressing roller to rotate relative to the rotating shaft.

[0013] As a further improvement of the present invention, the pressure roller is located between the two connecting blocks, and a limiting ring is provided between the pressure roller and the connecting block. The limiting ring is sleeved on the rotating shaft, and a limiting hole is provided on the surface of the limiting ring. A fixing member passes through the limiting hole and is connected to the rotating shaft to fix the limiting ring on the rotating shaft. The limiting ring restricts the position of the pressure roller on the rotating shaft from both sides.

[0014] As a further improvement of the present invention, bearings are provided at both ends of the hollow pressure roller, the inner diameter of the limiting ring is adapted to the outer diameter of the rotating shaft, and the side of the limiting ring facing the pressure roller abuts against the inner ring of the bearing.

[0015] As a further improvement of the present invention, the upper end of the spray pipe extends downwards to both sides to form a splash shield to prevent cooling water from splashing.

[0016] As a further improvement of the present invention, the bracket is bent, the connecting groove is located at the upper part of the bend, and the lower part of the bend is connected to the reel equipment frame by bolts.

[0017] As a further improvement of the present invention, the adjusting hole has an internal thread structure, the connecting member is a bolt, the bolt passes through the adjusting hole and abuts against the adjusting block, and after the position adjustment of the pressure roller is completed, the bolt is fixed by a nut.

[0018] As a further improvement of the present invention, the lower end face of the pressure roller is lower than the V-groove opening of the wire wheel of the transmission wire mesh.

[0019] Beneficial effects:

[0020] The pressure roller comes into contact with the wire mesh from above, forming an upward pressure constraint on the high-speed running wire mesh. When the wire mesh moves, it drives the pressure roller to rotate accordingly. This not only avoids generating additional resistance to the wire mesh transmission, but also directly counteracts the up-and-down fluctuation trend of the wire mesh caused by high-speed inertia, tension fluctuations, or liquid resistance through the continuous downward pressure of the pressure roller. This ensures that the wire mesh always stays within the preset transmission trajectory and completely solves the problem of cross-channeling caused by fluctuations deviating from the channel position when the wire mesh enters the V-groove.

[0021] The adjusting block inside the bracket connecting groove cooperates with the adjusting component that penetrates the groove. The adjusting component can push the adjusting block up and down along the connecting groove, thereby changing the height of the rotating shaft and the pressure roller, achieving precise control of the pressure roller's pressure on the wire mesh. This design not only meets the transmission constraints of diamond wires of different specifications (such as wire meshes with different diameters and tension requirements), but also avoids problems such as wire mesh deformation due to excessive pressure and inability to control fluctuations due to insufficient pressure. It has extremely high adaptability, effectively ensuring stable wire mesh transmission in various production scenarios, reducing wire breakage and merging faults at the source, and lowering the risk of production interruptions.

[0022] The spray structure positioned above the pressure roller can spray cooling water in a directional manner onto the pressure roller and wire mesh. On one hand, it can remove the heat generated by the friction between the wire mesh and the pressure roller and V-shaped wire wheel in real time, preventing the metal matrix of the wire mesh from softening and the surface diamond powder from falling off due to high temperature, effectively extending the service life of the wire mesh and ensuring the quality of diamond wire products. On the other hand, the cooling water can simultaneously clean the process residues (such as electroplating solution residues and dust impurities) attached to the surface of the wire mesh, reducing the interference of impurities on the transmission accuracy and subsequent sanding process, further improving the stability of diamond wire production quality. At the same time, the cooling water can also reduce the operating temperature of the pressure roller and rotating shaft, preventing the components from wearing out due to high temperature and extending the overall service life of the device.

[0023] As the core fixed structure of the device, the bracket can be firmly connected to the equipment frame to ensure the stability of the device in high-speed and vibrating production environments. The two ends of the rotating shaft are connected to the bracket through adjustment blocks, making the assembly process simple and installation can be completed without complicated debugging. It is compatible with the wire wheel drive system of existing mainstream diamond wire production equipment, eliminating the need for large-scale modification of the original equipment and reducing the equipment upgrade costs for enterprises.

[0024] This device can effectively reduce production downtime caused by wire mesh crosstalk, paralleling, and wire breakage, shorten equipment maintenance time, and significantly improve the continuity and efficiency of diamond wire production. At the same time, it reduces wire mesh scrap (such as wire mesh loss caused by wire breakage) and water waste, and lowers raw material and energy costs. In addition, the device has low manufacturing cost and high reliability, which can help enterprises reduce economic losses caused by production failures and create stable economic benefits for diamond wire production enterprises.

[0028] To better understand the purpose, structure, and function of this invention, the following detailed description of a diamond wire mesh transmission jump limiting device is provided in conjunction with the accompanying drawings.

[0029] Implementation example:

[0030] like Figure 1-2 As shown, a diamond wire mesh transmission jump limiting device is installed above the wire mesh by brackets 1 set on both sides of the wire wheel 7. In the sanding process of diamond wire production, the wire mesh in each groove is driven by two wire wheels 7 with V-shaped grooves. The pressure roller 3 presses the wire mesh from above and downwards, ensuring that the wire mesh will not jump out of the V-shaped groove during the operation of the wire wheel 7.

[0031] The bracket 1 is made of high-strength steel plate through bending, and the whole is bent. The lower part 15 of the bend is fixed to the wire wheel equipment frame by bolts. The upper part 14 of the bend is concave to form a U-shaped connecting groove 11. Adjusting holes 12 with internal threads are provided on the two sides and the bottom. In this embodiment, the adjusting component 13 is a bolt. The bolt enters the connecting groove 11 through the external thread structure and the internal thread of the adjusting hole 12. In the connecting groove 11, the adjusting block 4 is fixed in a suitable position by abutment and compression. The bolt entering the connecting groove 11 at the bottom adjusts the height of the adjusting block 4. After the bolts on both sides adjust the position in the left and right directions, they clamp the adjusting block 4. On the one hand, the lower part 15 is fixed to the wire wheel equipment frame to ensure that the device remains stable in the high-speed and vibrating production environment and avoid the impact of wire transmission accuracy due to device displacement. On the other hand, the connecting groove 11 of the upper part 14 of the bend provides installation space for the adjusting block 4. With the help of the adjusting holes 12, the position of the adjusting block 4 can be adjusted, thereby providing basic support for the height and pressure control of the pressure roller 3.

[0032] The adjusting block 4 is a block-shaped structure adapted to the connecting groove 11. A shaft hole 41 is provided in the center of the adjusting block for the end of the rotating shaft 2 to pass through and be fixed. There is an adjustment gap between the outer wall of the adjusting block 4 and the inner wall of the connecting groove 11, and the part in contact with the adjusting component has an anti-slip structure to prevent displacement after adjustment. The adjusting component 13 uses a bolt adapted to the internal thread of the adjusting hole 12. The bolt end has a flexible buffer layer to avoid wear caused by rigid contact with the adjusting block 4. Position adjustment is achieved through the threaded engagement of the adjusting component 13 and the adjusting hole 12. Tightening the adjusting component 13 at different positions pushes the adjusting block 4 to move up, down, left, and right along the connecting groove 11, thereby driving the rotating shaft 2 and the pressure roller 3 to rise and fall synchronously. This achieves precise control of the wire mesh pressure by the pressure roller 3. The position adjustment of the adjusting block 4 ensures that the lower end face of the pressure roller 3 is lower than the opening of the V-groove of the wire wheel and slightly higher than the bottom of the V-groove. The anti-slip structure and flexible buffer layer design ensure that the adjusting block 4 remains stable after adjustment, preventing pressure shift due to equipment vibration, and adapting to the transmission constraint requirements of different specifications of diamond wire.

[0033] The diameter of the rotating shaft 2 is adapted to the shaft hole 41 of the adjusting block 4, and its length is adapted to the width of the wire reel. Both ends of the rotating shaft 2 engage with the shaft holes 41 of the adjusting block 4, allowing for height changes as the adjusting block 4 moves. This provides stable rotational support for the pressure roller 3, ensuring its flexible rotation and transmitting the position adjustment effect of the adjusting block. The pressure roller 3 is made of wear-resistant material and has a hollow cylindrical structure. Its outer circumference is covered with a wear-resistant layer to reduce wear when in contact with the wire mesh. The inner wall of the pressure roller 3 is connected to the rotating shaft 2 via a bearing. The inner ring of the bearing is fixed to the rotating shaft 2, and the outer ring is fixed to the inner wall of the pressure roller 3, ensuring the pressure roller 3 can rotate flexibly around the rotating shaft. Simultaneously, the lower end face of the pressure roller 3 is designed with an opening lower than the V-groove of the wire reel, forming a limiting constraint on the wire mesh. The pressure roller 3 directly contacts the wire mesh from above. When the wire mesh moves at high speed, it drives the pressure roller to rotate accordingly. This avoids generating additional resistance to the transmission of the wire mesh and can also counteract the vertical fluctuation trend of the wire mesh through continuous downward pressure constraint, ensuring that the wire mesh is accurately embedded in the V-groove of the wire wheel and preventing the problem of cross-groove and wire merging from the root. The wear-resistant layer on the outer circumference can extend the service life of the pressure roller and prevent the constraint accuracy from decreasing due to long-term wear.

[0034] The spray structure 5 includes a spray pipe and a spray interface. The spray pipe 52 is made of corrosion-resistant metal tubing, and its length is adapted to the rotating shaft 2. Several spray holes are opened on the side of the pipe facing the pressure roller 3, and the spray holes are evenly distributed along the length of the spray pipe 52. The spray interface 51 is located at one end of the spray pipe 52 and is used to connect to an external cooling water source through a pipe. The upper end face of the spray pipe 52 is provided with a splash guard 53 that is inclined downwards to both sides to avoid irregular splashing of cooling water after contact with the pressure roller 3. External cooling water enters the spray pipe 52 through the spray interface 51 and is sprayed directionally onto the pressure roller 3 through the spray holes. On the one hand, it can remove the heat generated by the friction between the wire mesh and the pressure roller 3 in real time, avoiding the degradation of the wire mesh material performance due to high temperature; on the other hand, the cooling water can simultaneously wash away the process residues attached to the surface of the wire mesh, reducing the interference of impurities on the transmission accuracy and subsequent processes, and improving the quality of diamond wire products; at the same time, the cooling water can also play an auxiliary lubricating role for the pressure roller, further reducing rotational resistance.

[0035] The connecting blocks 6 are vertically arranged. A lower connecting hole 62 is provided at the bottom of the connecting blocks 6, through which both ends of the rotating shaft 2 pass. The connecting blocks 6 are then secured to the rotating shaft 2 by bolts (passing through internal threaded holes on the side). An upper connecting hole 61 is provided at the top of the connecting blocks 6, through which both ends of the spray pipe 52 pass, and are also secured by bolts, forming a vertically integrated structure of the rotating shaft 2, connecting blocks 6, and spray pipe 52. The spray structure 5 needs to spray cooling water directionally towards the pressure roller 3. If the spray pipe 52 is misaligned (e.g., tilted vertically or misaligned horizontally), the cooling water will lose its cooling and cleaning effect. The connecting block 6 secures the rotating shaft 2 and the spray pipe 52 via upper and lower connecting holes, rigidly integrating the two. When the adjusting block 4 moves the rotating shaft 2 up and down to adjust the height of the pressure roller 3, the connecting block 6 simultaneously moves the spray pipe 52 up and down with the rotating shaft, ensuring that the spray holes of the spray pipe 52 are always aligned with the pressure roller 3, preventing the spray position from shifting due to height adjustment, and maintaining stable cooling and cleaning functions. If the spray pipe is independently fixed on the bracket, a separate adjustment mechanism for the spray pipe is required, which increases the structural complexity of the device and the assembly steps. With the connecting block, there is no need for additional adjustment of the spray pipe. When the height of the rotating shaft is adjusted by the adjusting block, the spray pipe can be synchronously adapted, simplifying the assembly process. During later maintenance (such as replacing the pressure roller or cleaning the spray pipe), only the bolts on the connecting block need to be removed to separate the components, making operation convenient and reducing maintenance costs.

[0036] A limiting ring 31 is positioned between both ends of the pressure roller 3 and the connecting block 6. One end of the limiting ring 31 abuts against the outer ring of the bearing at the end of the pressure roller 3. A through-hole is formed on the surface of the limiting ring 31. A bolt passes through the limiting hole and abuts against the outer wall of the rotating shaft 2, thus axially fixing the limiting ring 31 on the rotating shaft 2 and preventing it from shifting with the rotation of the pressure roller or equipment vibration. The pressure roller 3 must always maintain direct contact with the wire mesh. If the pressure roller 3 slides axially along the rotating shaft 2, its contact position with the wire mesh will shift (e.g., towards the edge of the wire mesh), resulting in a loss of effective constraint on the wire mesh, or even scraping the wire mesh and causing wire breakage. The limiting ring 31, through rigid contact with the end of the pressure roller 3, directly limits the axial position of the pressure roller 3 on the rotating shaft 2, preventing it from sliding due to vibration, inertia, or bearing clearance. This ensures that the pressure roller 3 always covers the effective transmission area of ​​the wire mesh and maintains a stable downward pressure constraint effect.

[0037] The device of this invention uses a pressure roller as its core to constrain wire mesh movement. Combined with a height-adjustable adjustment block structure, it can both rigidly press down to counteract the vertical fluctuations of the wire mesh during high-speed operation, completely eliminating problems such as cross-grooving, wire merging, and wire breakage, and precisely adjust the pressure according to the transmission requirements of different specifications of diamond wire. Its adaptability covers mainstream production scenarios, reducing the risk of production interruptions at the source. Cooling and cleaning functions are integrated into a spray structure. Cooling water can remove frictional heat in real time to protect wire mesh performance and wash away process residues to improve product quality, eliminating the need for separate equipment. Simultaneously, the integrated anti-splash design of the spray pipe reduces water waste and equipment contamination, simplifying the structure and reducing energy consumption and maintenance costs while ensuring functionality. A limiting ring precisely limits the axial position of the pressure roller, and a connecting block achieves rigid linkage between the rotating shaft and the spray pipe. Bearings ensure flexible transmission, and high-strength materials and wear-resistant processes extend component life, effectively resisting vibration, wear, and media corrosion in the production environment, thus extending the overall service life of the device. With its modular design and flexible installation structure, it can be directly adapted to existing diamond wire production equipment without large-scale modifications. Each core component is detachably connected, and the replacement of vulnerable parts is simple and requires no special tools, which can significantly reduce the time and financial costs of equipment maintenance and facilitate its promotion and application in the industry.
