[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 9 As shown in the figure, a rubber roller grinding machine according to an embodiment of the present invention includes four support legs 1;

[0040] Support plates 46 are fixedly installed on the top of the two support legs 1 located on the same side, and a grinding mechanism 2 is fixedly connected to the top of the support plates 46 for grinding the rubber roller.

[0041] A cleaning mechanism 3 is fixedly installed on the top of the support plate 46 for cleaning the rubber roller;

[0042] A feeding mechanism 4 is fixedly installed on one side of each of the two support plates 46, which is used to transport the rubber roller to the cleaning mechanism 3 and the polishing mechanism 2 to treat the surface of the rubber roller.

[0043] A debris collection box 5 is fixedly installed in the middle of the four support legs 1 to collect debris generated during grinding and cleaning of the rubber roller surface;

[0044] The grinding mechanism 2 includes a support frame 21, which is fixedly installed on the top of the support plate 46. The bottom of the support frame 21 has a groove 22, and a slider 23 is slidably installed on the inner surface of the groove 22. A threaded hole 231 is opened in the middle of the slider 23, and a threaded rod 24 is threadedly installed on the inner surface of the threaded hole 231. A cylinder 27 is fixedly connected to the bottom of the slider 23, and a power mechanism 28 is fixedly connected to the bottom of the cylinder 27.

[0045] The power mechanism 28 includes a second motor 281, which is fixedly mounted at the bottom of the cylinder 27. A grinding wheel 282 is fixedly connected to the transmission shaft at the output end of the second motor 281. A helical gear 283 is fixedly mounted on the side of the grinding wheel 282 near the second motor 281. An L-shaped connecting rod 284 is fixedly connected to one side of the second motor 281. A helical gear 285 is rotatably mounted at the bottom of the L-shaped connecting rod 284. The helical gear 285 meshes with the helical gear 283. A fan blade 286 is fixedly mounted at the bottom of the helical gear 285. A threaded rod 24 is fixedly connected to the transmission shaft at the output end of a first motor 25 at one end. The first motor 25 is fixedly mounted on one side of a support frame 21. The threaded rod 24 is rotatably mounted on the inner surface of a groove 22. A shaped groove 26 is provided on one side of the support frame 21. The outline of the shaped groove 26 is the same as the cross-sectional dimensions of the power mechanism 28.

[0046] To achieve the purpose of cooling the surface of the rubber roller during grinding, in one embodiment of the present invention, the rubber roller is transported to the cleaning mechanism 3 via the feeding mechanism 4 for cleaning. The cleaned-off debris falls into the debris collection box 5. When the rubber roller is transported to the grinding mechanism 2, the second motor 281 drives the grinding wheel 282 to rotate. The rotating grinding wheel 282 contacts the surface of the rubber roller, grinding the surface of the rubber roller in the device. When the grinding wheel 282 rotates, it can drive the helical gear 283 to rotate. When wheel 283 rotates, it drives helical gear 285 to rotate. Helical gear 285 is connected to a fan blade 286 below it. When grinding the rubber roller, the fan blade 286 rotates with the grinding wheel 282 and faces the grinding area of ​​the grinding wheel 282 and the rubber roller. It can dissipate heat at the grinding area when grinding the rubber roller, so as to avoid the surface temperature of the rubber roller becoming too high after grinding, which would damage the surface of the rubber roller and affect the smoothness of the surface. It can also blow the waste generated by grinding into the waste collection box 5, which makes it convenient for the staff to collect and process the waste.

[0047] The top of motor 281 is fixedly connected to cylinder 27. The rubber roller grinding device adjusts the position of motor 281 and grinding wheel 282 through cylinder 27, and adjusts the distance between grinding wheel 282 and rubber roller surface through cylinder 27. The top of cylinder 27 is fixedly connected to slider 23. The position of slider 23 is controlled by threaded rod 24. Slider 23 slides on the inner surface of groove 22. Threaded rod 24 is controlled by motor 25.

[0048] The outer contour of the irregular groove 26 is the same as that of the motor 281 in the power mechanism 28. Therefore, by rotating the threaded rod 24, the slider 23 can be driven to move. During the movement of the slider 23 towards the irregular groove 26, the motor 281 can move into the irregular groove 26. This design allows the grinding wheel 27 to grind the entire side of the rubber roller in the device without the position of the grinding wheel 27 being affected by the motor 25 hitting the side wall of the support frame 21, which would prevent the grinding wheel 27 from being unable to grind the entire surface of the rubber roller in the device.

[0049] like Figure 6 As shown, the cleaning mechanism 3 includes a second support frame 31, which is fixedly installed on the top of the support plate 46. An electric telescopic rod 32 is fixedly installed at the bottom of the second support frame 31. A connecting plate 33 is fixedly installed at the bottom of the electric telescopic rod 32. Four springs 34 are fixedly installed at the bottom of the connecting plate 33. A cleaning plate 35 is fixedly installed at the bottom of each spring 34. A cleaning strip 351 is fixedly installed on one side of the cleaning plate 35. The cleaning plate 35 on the other side of the cleaning strip 351 is arc-shaped.

[0050] To prevent impurities on the surface of the rubber roller in this device from rubbing against the roller surface during the grinding process and affecting the grinding accuracy, in one embodiment of the present invention, the rubber roller rotates as it moves below the grinding mechanism 2. The electric telescopic rod 32 adjusts the positions of the connecting plate 33 and the cleaning plate 35 according to the diameter of the rubber roller, so that the cleaning plate 35 can contact the surface of the rubber roller. The first contact point between the cleaning plate 35 and the rubber roller is the arc-shaped area of ​​the cleaning plate 35. This structural design can effectively prevent the rubber roller from failing to pass through the cleaning plate 35. During the process, the debris and residue on the surface of the rubber roller will be scraped off by friction. After the rubber roller passes through the arc-shaped area of ​​the cleaning plate 35, the rubber roller contacts the cleaning strip 351. During the contact between the rubber roller and the cleaning plate 35, the cleaning plate 35 will be lifted up and the spring 34 will contract. After the rubber roller leaves the cleaning strip 351, the cleaning plate 35 will move downward due to the action of the spring 34 and the gravity of the cleaning plate 35 itself. Under the action of the spring 34, the cleaning plate 35 will vibrate. During the vibration, the waste residue on the cleaning plate 35 will fall into the debris collection box 5.

[0051] like Figures 7 to 8 As shown, the feeding mechanism 4 includes two sliding plates 41, which are respectively fixedly installed on both sides of the support leg 1. A groove 42 is formed on the top of each sliding plate 41, and a T-shaped sliding plate 43 is slidably installed on the inner surface of the groove 42. A motor 44 is fixedly installed on the top of the T-shaped sliding plate 43. A groove 47 is formed on one side of the support plate 46, and a groove 48 is formed on the inner surface of the groove 47. A rack 45 is fixedly installed on the top of each sliding plate 41. A gear 441 is fixedly installed on the output shaft of the motor 44. A clamping block 442 and a fixing block 443 are fixedly installed. A clamping block 444 is slidably connected to the outer surface of the fixing block 443. Two limiting holes 445 are opened on the top of the clamping block 444. A limiting rod 446 is slidably installed on the inner surface of the limiting hole 445. A threaded hole 447 extending into the interior of the fixing block 443 is opened on the clamping block 444. A threaded rod 448 is threadedly installed on the inner surface of the threaded hole 447. An arc groove 4421 is opened on the opposite surface of the clamping block 444. The gear 441 meshes with the rack 45.

[0052] To achieve the purpose of moving the rubber roller, in one embodiment of the present invention, a T-shaped slide plate 43 slides on the inner surface of groove 2 42. The power source of the T-shaped slide plate 43 is a motor 3 44. When the motor 3 44 rotates, the gear 441 and rack 45 mounted on the transmission shaft at the output end of the motor 3 44 mesh with each other. The rotation of the gear 441 can change the position of the motor 3 44. The transmission shaft at the output end of the motor 3 44 slides on the inner surface of groove 48, and the diameter of the output shaft of the motor 3 44 is the same as the height of groove 48. Gears 441 and racks 45 are mounted on both sides of the rubber roller polishing device. After the rubber roller is clamped, the gears 441 on both sides rotate synchronously. This design allows the rubber roller to rotate smoothly through the cleaning mechanism 3 and move to the polishing mechanism 2. Below, the output shaft of motor 3 44 is equipped with clamping block 1 442 and fixing block 443. Clamping block 2 444 slides above fixing block 443. Clamping block 2 444 is controlled by threaded rod 2 448 and threaded hole 2 447 to enable the rubber roller grinding machine to grind rubber rollers of different diameters. Limiting rods 446 on both sides of threaded rod 2 448 can restrict clamping block 2 444 to only move in a straight line. Arc grooves 4421 are opened on the close surfaces of clamping block 1 442 and clamping block 2 444, which is beneficial for clamping and fixing cylindrical rubber rollers. This design enables the feeding mechanism 4 to complete the function of clamping and controlling the movement of rubber rollers, reducing manual operation procedures and improving processing efficiency.

[0053] like Figure 9 As shown, the slide plates 41 on both sides of the rack 45 are provided with grooves 461. The inner surface of the grooves 461 has two grooves 462. The inner surface of the two grooves 462 is slidably mounted with slide rods 463. One end of the two slide rods 463 is fixedly mounted with a toothed plate 464. The toothed plate 464 is slidably mounted on the inner surface of the grooves 461. The inner surface of the grooves 461 has a through hole 465. The inner wall of the through hole 465 is fixedly mounted with a spring 466. The other end of the spring 466 is fixedly connected to the toothed plate 464.

[0054] To achieve the purpose of limiting the feeding mechanism 4, in one embodiment of the present invention, the width of the top of the toothed plate 464 is the same as the width of the top of the rack 45. When the gear 441 contacts the rack 45 and changes the position of the feeding mechanism 4, the spring 466 pushes the toothed plate 464 outward from the through hole 465. The pushed-out toothed plate 464 can contact the gear 441 and be subjected to force. After the rubber roller is clamped, the gear 441 contacts the toothed plate 464, and the gear 441 pushes the toothed plate 464 away from the rack 45. Since the distance between the toothed plate 464 and the rack 45 is short, the gear 441 can continue to move forward and contact the rack. The rack 45 and gear 441 work together to move the rubber roller. When the roller moves to the bottom of the grinding mechanism 2, the gear 441 is at the end of the rack 45 and contacts the toothed plate 464 on that side. Since the spring 466 is always pushing the toothed plate 464, the gear 441 can no longer bear force. The feeding mechanism 4 rotates the rubber roller under the grinding mechanism 2 but does not change its position. The grinding mechanism 2 can grind the rubber roller. After grinding, the gear 441 rotates in the opposite direction and returns the rubber roller to the initial position, which makes it easy for the staff to unload the ground rubber roller and install the rubber roller that needs to be ground.

[0055] Working principle: First, place the rubber roller in the arc groove 4421. Adjust the position of the clamping block 444 by the threaded rod 448. The clamping block 442 and the clamping block 444 cooperate to clamp the rubber roller. The motor 44 controls the gear 441 and the rack 45 to mesh and rotate, thereby controlling the movement of the rubber roller.

[0056] During the movement of the rubber roller, the rubber roller rotates. The electric telescopic rod 32 adjusts the position of the cleaning plate 35 according to the diameter of the rubber roller. When the rubber roller passes the cleaning plate 35, the surface of the rubber roller rubs against the surface of the cleaning plate 35. The cleaning plate 35 wipes away the debris on the surface of the rubber roller. When the rubber roller is separated from the cleaning strip 351, the cleaning plate 35 shakes due to the action of the spring 34. The debris stuck on the cleaning plate 35 falls into the debris collection box 5.

[0057] When the rubber roller moves below the grinding mechanism 2, under the combined action of the toothed plate 464 and the second spring 466, the third motor 44 stops below the grinding mechanism 2. At this time, the third motor 44 continues to rotate the rubber roller, but the position of the rubber roller will not change. At this time, the second motor 281 rotates the grinding wheel 282. The first threaded rod 24 and the first slider 23 control the lateral position of the grinding wheel 282. The cylinder 27 adjusts the vertical position of the grinding wheel 282 according to the diameter of the rubber roller to grind the rubber roller. During the grinding process, the transmission shaft at the output end of the second motor 281 rotates the first helical gear 283, the first helical gear 283 rotates the second helical gear 285, and then the second helical gear 285 can rotate the fan blade 286. The rotation of the fan blade 286 causes air flow, blowing air towards the grinding position to cool the grinding point and avoid affecting the grinding accuracy of the rubber roller due to excessive grinding temperature.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
