Description
Technical Field

[0002] In modern metal processing and manufacturing, rolling rolls are the core components of rolling mills, widely used in the rolling production process of materials such as steel and non-ferrous metals. The surface quality and performance of rolling rolls play a decisive role in the quality, precision, and production efficiency of rolled products.
[0003] In terms of traditional roll surface treatment, many existing systems use simple fixed grinding structures, which are difficult to adjust flexibly according to different roll sizes and surface conditions. This results in poor grinding uniformity and precision, failing to meet the stringent requirements of high-precision rolling for roll surface quality.
[0004] Moreover, in terms of roll clamping, traditional clamps are not very adaptable to rolls of different specifications. When it is necessary to process rolls of different diameters or lengths, the entire clamping system often needs to be replaced, which greatly reduces production efficiency and increases production costs.

[0009] As a further technical solution of this utility model, the grinding bracket is C-shaped, and a third motor is fixedly connected to one side of the grinding bracket. One end of the output shaft of the third motor is connected to one of the rotating rollers. A water storage tank is provided above the grinding bracket and is bolted to the grinding bracket. Multiple water spray nozzles are provided on one side of the water storage tank.
[0010] As a further technical solution of this utility model, the bottom of the slide table is connected to a second lead screw.

The second slide rail is fixedly connected to the base. The slide table is installed with the second slide rail and is slidably connected to the base.
[0011] As a further technical solution of this utility model, the slide is provided with two cylinders. The bottom of the cylinder is fixedly connected to the slide via a fixing rod. One end of the cylinder rod is connected to a connecting rod fixedly connected to the grinding bracket.
[0012] As a further technical solution of this utility model, the bottom of the clamp seat that is slidably connected to the base is provided with a sliding groove, and a first slide rail is fixedly connected to the inner wall on both sides of the sliding groove. A slide seat is connected to the first slide rail and is fixedly connected to the clamp seat. A first lead screw is provided at the bottom of the sliding groove. The first lead screw is rotatably connected to the slide seat. Both ends of the first lead screw are rotatably connected to the base, and one end extends to the outside of the base and is fixedly connected to a wheel.
[0013] As a further technical solution of this utility model, the slide block and the base have multiple positioning holes at the edge of the slide groove, which are distributed in a regular manner.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this invention, multiple rotating rollers drive the sanding belt to rotate, forming a highly efficient grinding structure. Compared with traditional systems with a single grinding component, multiple rotating rollers enable the sanding belt to have a larger and closer contact with the surface of the roll, increasing the effective grinding area and grinding frequency, thereby significantly improving grinding efficiency and completing the treatment of the roll surface in a shorter time.
[0017] This invention features a fixed clamping seat and a sliding clamping head, which, together with the conical chuck, enhances the system's adaptability to rolls of different lengths and diameters. The sliding clamping seat can be flexibly adjusted according to the actual length of the roll, while the conical chuck can better fit the ends of rolls of different diameters, achieving stable clamping. This eliminates the need for frequent clamping changes to adapt to different roll specifications, thus improving production efficiency.
[0018] In this invention, the water tank and spray nozzle above the grinding bracket can spray water onto the surface of the roll in a timely manner during the grinding process, which plays a good cooling role. Since the friction between the roll and the sanding belt during grinding generates a lot of heat, the high temperature may cause the roll to deform thermally, affecting its dimensional accuracy and performance. By spraying water for cooling, the surface temperature of the roll can be reduced, the risk of thermal deformation can be reduced, and the service life of the roll can be extended.

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-7 In this embodiment of the utility model, a base 1 is included. A rectangular groove is provided on one side of the base 1, and a slide 2 is provided in the groove. A grinding bracket 3 is movably connected to the surface of the slide 2. A plurality of rotating rollers 4 are provided in the grinding bracket 3, and the rotating rollers 4 are all rotatably connected to the grinding bracket 3. A sanding belt 5 is provided on the outer wall of the rotating roller 4 and is in close contact with the rotating roller 4 and rotatably connected.
[0029] By adopting the above technical solution, the slide table 2 can move within the rectangular groove of the base 1, which allows the grinding bracket 3 to be positioned according to the specific conditions of the roll. The operator can precisely move the grinding bracket 3 to the part of the roll that needs to be ground, thus achieving targeted grinding operations. At the same time, multiple rotating rollers 4 drive the sanding belt 5 to rotate, so that the sanding belt 5 has a larger contact area with the roll surface, improving grinding efficiency. Moreover, multiple rotating rollers 4 can ensure that the sanding belt 5 is subjected to uniform force during rotation, thereby achieving uniform grinding of the roll surface, effectively removing defects such as wear and oxide scale from the roll surface, significantly improving the flatness and smoothness of the roll surface, and laying a solid foundation for the subsequent rolling of high-quality products.
[0030] In this embodiment, the grinding bracket 3 is provided with two clamp seats 8 on one side. One clamp seat 8 is bolted to the base 1, and the other clamp seat 8 is slidably connected to the base 1. Each of the two clamp seats 8 is fitted with a chuck 81, and the chuck 81 is conical in shape and is rotatably connected to the clamp seat 8 through a bearing. The chuck 81 has a roller 9 in the middle, and the roller 9 has grooves at both ends, which are tightened and fixed by the chuck 81.
[0031] By adopting the above technical solution, one clamp seat 8 is bolted to the base 1 to serve as a fixed reference, and the other clamp seat 8 is slidably connected to the base 1. This design allows the distance between the two clamp seats 8 to be flexibly adjusted according to the length of the roll 9 to be processed. For rolls 9 of different lengths, simply slide the movable clamp seat 8 to the appropriate position to easily achieve clamping, which greatly improves the versatility for rolls 9 of different lengths, reduces the trouble of changing clamping equipment due to differences in the length of rolls 9, and improves production efficiency.
[0032] Furthermore, the conical design of the chuck 81 can accommodate the ends of rolls 9 of different diameters. When clamping rolls 9 of different diameters, the conical chuck 81 can achieve stable clamping by closely fitting with the ends of the rolls, further enhancing the system's adaptability to rolls 9 of different specifications.
[0033] In this embodiment, the grinding bracket 3 is C-shaped. A third motor 16 is fixedly connected to one side of the grinding bracket 3. One end of the output shaft of the third motor 16 is connected to one of the rotating rollers 4. A water storage tank 7 is provided above the grinding bracket 3 and is bolted to the grinding bracket 3. A plurality of water spray nozzles 6 are provided on one side of the water storage tank 7.
[0034] By adopting the above technical solution, the third motor 16 is fixedly connected to one side of the grinding bracket 3, and its output shaft is connected to one of the rotating rollers 4. This direct power transmission method reduces energy loss in the power transmission process and ensures that the rotating roller 4 can obtain stable and strong power. The third motor 16 can accurately control the speed and direction of rotation of the rotating roller 4, thereby achieving precise control of the movement state of the sanding belt 5. The stable power drive enables the sanding belt 5 to maintain uniform and stable operation during the grinding process, further improving the grinding accuracy and effect.
[0035] Furthermore, during the grinding process, the high-speed friction between the abrasive belt 5 and the surface of the roll 9 generates a large amount of heat. The water tank 7 is located above the grinding bracket 3 and is fixed by bolts to ensure its installation stability. Multiple water spray nozzles 6 on one side of the water tank 7 can spray water onto the surface of the roll 9 in a timely manner. The cooling effect of the water can effectively reduce the temperature of the surface of the roll 9, prevent problems such as thermal deformation and reduced hardness of the roll 9 surface caused by high temperature, and extend the service life of the roll 9.
[0036] In this embodiment, the bottom of the slide table 2 is connected to a second lead screw 18. Both ends of the second lead screw 18 are rotatably connected to the base 1 through bearings, and one end extends to the outside of one side of the base 1 and is connected to a second motor 15. The second motor 15 is fixedly connected to one side of the base 1. The rectangular groove opened on the base 1 is provided with a second slide rail 19 on both sides. The second slide rail 19 is fixedly connected to the base 1. The slide table 2 is installed with the second slide rail 19 and is slidably connected to the base 1.
[0037] By adopting the above technical solution, the bottom of the slide table 2 is connected to the second lead screw 18. The second lead screw 18 rotates under the drive of the second motor 15, which can accurately convert the rotational motion of the second motor 15 into the linear motion of the slide table 2. The operator can precisely adjust the position of the slide table 2 in the rectangular groove of the base 1 by controlling the number of rotations, direction and speed of the second motor 15. This allows the grinding bracket 3 to accurately reach the part of the roll 9 that needs to be ground, meet the surface treatment requirements of rolls 9 of different specifications and different grinding needs, and greatly improve the accuracy of the grinding operation.
[0038] In this embodiment, the slide table 2 is provided with two cylinders 17. The bottom of the cylinder 17 is fixedly connected to the slide table 2 through a fixing rod. One end of the cylinder rod of the cylinder 17 is connected to the connecting rod 31 fixedly connected to the grinding bracket 3.
[0039] By adopting the above technical solution, the two cylinders 17 set on the slide table 2 can precisely adjust the height of the grinding support 3 by controlling the extension and retraction length of the cylinder rods of the cylinders 17. For rolls 9 with larger diameters, the cylinder rods of the cylinders 17 can be extended to raise the grinding support 3; for rolls 9 with smaller diameters, the cylinder rods can be retracted to lower the height of the grinding support 3. This flexible height adjustment capability enables the surface treatment system to adapt to the grinding requirements of rolls 9 of various specifications, greatly improving the versatility and applicability of the equipment.
[0040] In this embodiment, a sliding groove is provided on the bottom of the clamp seat 8 which is slidably connected to the base 1, and a first slide rail 20 is fixedly connected to the inner wall on both sides of the sliding groove. A slide seat 12 is connected to the first slide rail 20 and is fixedly connected to the clamp seat 8. A first lead screw 13 is provided at the bottom of the sliding groove. The first lead screw 13 is rotatably connected to the slide seat 12. Both ends of the first lead screw 13 are rotatably connected to the base 1, and one end extends to the outside of the base 1 and is fixedly connected to a wheel 14.
[0041] By adopting the above technical solution, different rolls 9 have different length specifications. The clamp seat 8, which is slidably connected to the base 1 in the system, can move flexibly. When the operator rotates the turntable 14, the first lead screw 13 rotates accordingly. Since the first lead screw 13 is rotatably connected to the slide 12, the slide 12 will move along the first slide rail 20 in the slide groove, thereby driving the clamp seat 8, which is fixedly connected to it, to move. In this way, the distance between the two clamp seats 8 can be easily adjusted to adapt to rolls 9 of different lengths, which greatly improves the system's clamping capability for rolls 9 of different specifications and enhances the versatility of the equipment.
[0042] In this embodiment, the slide block 12 and the base 1 have multiple positioning holes at the edge of the slide groove, which are distributed in a regular pattern.
[0043] By adopting the above technical solution, when adjusting the position of the clamp seat 8 which is slidably connected to the base 1, the slide seat 12 moves along the first slide rail 20. When the clamp seat 8 moves to a position suitable for the length of the roll 9 to be processed, the positioning holes regularly distributed at the edge of the slide groove opened by the slide seat 12 and the base 1 can be used to precisely fix the slide seat 12 in the current position by inserting positioning pins and other positioning elements. In this way, the clamp seat 8 can be stably maintained in the set position, ensuring that both ends of the roll 9 are accurately clamped. This effectively avoids the displacement of the roll 9 caused by the change in the position of the clamp seat 8 during the subsequent grinding process, greatly improving the positioning accuracy of the roll 9 clamping and laying the foundation for high-quality surface treatment.
[0044] In this embodiment, on the clamp seat 8 bolted to the base 1, one end of the clamp 81 is located inside the clamp seat 8, and the other end extends to the outside of the clamp seat 8. A pulley is installed at the end of the clamp 81 extending to the outside. A first motor 10 is provided on one side of the clamp seat 8. The first motor 10 is fixedly connected to the base 1, and a motor cover 11 is provided outside the first motor 10. A pulley is installed at one end of the output shaft of the first motor 10, and is connected to the pulley installed at the end of the clamp 81 extending to the outside by a belt drive.
[0045] By adopting the above technical solution, the first motor 10 serves as a power source, and the pulley at one end of its output shaft is connected to the pulley at the end of the chuck 81 via belt drive. Belt drive has the function of buffering and shock absorption, which can effectively reduce the vibration and impact generated during motor operation and transmit them to the chuck 81 and the roll 9. This makes the power transmission more stable, ensures the stability of the roll 9 during rotation, avoids problems such as uneven grinding or surface quality defects caused by vibration, and helps to improve the precision and quality of the surface treatment of the roll 9.
[0046] Furthermore, a motor cover 11 is provided outside the first motor 10. The motor cover 11 can play a protective role, preventing dust, metal shavings, water and other impurities from entering the motor and avoiding the motor from being affected by pollution or damage, thus preventing the motor from operating normally.
[0047] The working principle of this utility model is as follows: First, according to the length of the roll 9 to be processed, the operator rotates the rotating wheel 14, which drives the first lead screw 13 connected to it to rotate. Since the first lead screw 13 is connected to the slide block 12 and the slide block 12 is installed on the first slide rail 20, the slide block 12 will move along the first slide rail 20 in the slide groove of the base 1, thereby driving the slidable clamp seat 8 fixedly connected to the slide block 12 to move, so as to adjust the distance between the two clamp seats 8 to match the length of the roll 9. After the adjustment is in place, the positioning pin is inserted into the positioning hole at the edge of the slide block 12 and the slide groove of the base 1 to fix the slide block 12 and ensure that the position of the clamp seat 8 is stable.
[0048] Start the second motor 15, which drives the second lead screw 18 to rotate. The bottom of the slide table 2 is connected to the second lead screw 18. At the same time, the slide table 2 is installed on the second slide rail 19. The rotation of the second lead screw 18 drives the slide table 2 to move along the second slide rail 19 in the rectangular groove of the base 1, thereby moving the grinding bracket 3 installed on the slide table 2 to the appropriate grinding starting position.
[0049] The third motor 16 is turned on, and its output shaft drives the rotating roller 4 to rotate. Since multiple rotating rollers 4 are rotatably connected to the grinding bracket 3, and the sanding belt 5 is attached to the outer wall of the rotating roller 4, the rotation of the rotating roller 4 causes the sanding belt 5 to circulate on the multiple rotating rollers 4, starting the grinding of the roller surface. The first motor 10 is started, and the pulley on the output shaft of the first motor 10 drives the pulley at the end of the chuck 81 to rotate via a belt. The rotation of the chuck 81 then drives the roller to rotate. During the rotation of the roller, the sanding belt 5 continuously grinds its surface circumferentially to ensure the uniformity of the grinding. At the same time, the position of the slide table 2 and the height of the grinding bracket 3 can be finely adjusted again according to the grinding situation to ensure that the sanding belt 5 can grind the surface of the roller 9 comprehensively and evenly. During the grinding process, water in the water tank 7 is sprayed onto the surface of the roller 9 through multiple water spray nozzles 6 on one side, which can reduce the heat generated by the friction between the sanding belt 5 and the surface of the roller 9, prevent the roller 9 from deforming due to high temperature, and extend the service life of the roller 9 and the sanding belt 5.
