Description

Technical Field

[0001] This invention relates to the field of rubber roller grinding technology, and in particular to a rubber roller grinding apparatus. Background Technology

[0002] As the rubber rollers are manufactured and processed and used for a long time, their surfaces become rough and have residues attached, requiring grinding equipment to process and grind them.

[0003] There are many methods for grinding rubber rollers, among which the most common is grinding the roller surface using the sharp edges of an abrasive wheel. However, during the grinding process, the roller and the abrasive wheel mainly come into contact and rotate relative to each other. Since the roller shaft diameter varies, the position of the abrasive wheel must also change, leading to inconsistent precision when grinding rollers of different sizes.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Reference Figures 1-6 The present invention provides a rubber roller grinding device, comprising:

[0045] The worktable 1 has a rubber roller 2 rotatably fitted on its top surface. The worktable 1 is equipped with a clamping assembly connected to the rubber roller 2. The rubber roller 2 and the clamping assembly are detachably connected.

[0046] The grinding wheel 3 is connected to the top surface of the workbench 1 on the side opposite to the rubber roller 2, and rotates in the opposite direction to the rubber roller 2. The workbench 1 is equipped with a three-axis drive mechanism, and the drive end of the three-axis drive mechanism is connected to the grinding wheel 3 so that the cutting edge of the grinding wheel 3 rolls in contact with the outer ring of the rubber roller 2.

[0047] The vibration detection assembly includes a detection wheel 4 that rolls in contact with the outer ring of the rubber roller 2. The detection wheel 4 is elastically connected to the worktable 1, and a pressure signal meter 5 is provided on the worktable 1. The pressure signal meter 5 is used to acquire the pressure signal of the detection wheel 4.

[0048] A vision acquisition component is set on the detection wheel 4 or the grinding wheel 3 to acquire the position of the grinding wheel 3 or the detection wheel 4, wherein the outer periphery of the rubber roller 2 overlaps with the area of ​​the detection wheel 4 and the grinding wheel 3 in rolling contact.

[0049] This invention utilizes a clamping assembly to detachably connect the rubber roller 2 to the worktable 1, meeting the grinding requirements of rubber rollers 2 of different sizes. A three-axis drive mechanism drives and controls the grinding wheel 3, allowing the grinding wheel 3 to roll and contact the outer periphery of the rubber roller 2 according to its position, based on the different diameters of the rubber roller 2, for grinding operations. Furthermore, during the grinding process, a detection wheel 4 rolls and contacts the rubber roller 2. When the detection wheel 4 comes into contact with residue on the rubber roller 2, the undulation of the contact surface causes the detection wheel 4 to elastically bounce, which is then converted into a pressure signal change on the pressure signal meter 5, thereby detecting the degree of grinding on the surface of the rubber roller 2. A vision acquisition component positions the grinding wheel 3 and the detection wheel 4 accordingly, ensuring that the areas of rolling contact between the grinding wheel 3 and the detection wheel 4 and the rubber roller 2 overlap, achieving precise point-to-point grinding of the rubber roller 2 surface and improving the grinding effect on rubber rollers 2 with different shaft diameters.

[0050] Furthermore, the width of the detection wheel 4 and the grinding wheel 3 are the same, and at least two detection wheels 4 are provided along the axial direction of the rubber roller 2.

[0051] By keeping the width of the detection wheel 4 consistent with that of the grinding wheel 3, and with the accurate positioning of the vision acquisition component, the grinding area of ​​the grinding wheel 3 and the detection area of ​​the detection wheel 4 are kept consistent, thus improving the grinding effect. Furthermore, by setting up several detection wheels 4 and correspondingly setting up several pressure signal instruments 5, the pressure signals are detected and the changes in pressure signals on several detection wheels 4 are compared to determine whether the detection wheel 4 that produces the jumping change accurately detects the presence of deposits on the surface of the rubber roller 2.

[0052] Specifically, when only one of the several detection wheels 4 shows a pressure signal fluctuation, it can be determined that there is an adhering object in the corresponding rolling contact area on the rubber roller 2. When all of the several detection wheels 4 show pressure signal fluctuations, it can be determined that the clamping position of the rubber roller 2 has shifted or the grinding position of the grinding wheel 3 has deviated. Thus, the position of the rubber roller 2 or the grinding wheel 3 can be corrected and adjusted in time to improve the grinding effect.

[0053] Furthermore, the detection wheel 4 is made of metal or other hard materials to avoid elastic deformation of the detection wheel 4 itself affecting the accuracy of the pressure signal transmitted by the detection wheel 4.

[0054] Furthermore, it also includes:

[0055] The connecting assembly includes a first linear guide rail 6 fixed to the top surface of the workbench 1. The length direction of the first linear guide rail 6 is parallel to the axial direction of the rubber roller 2. A first slider 7 is slidably connected on the first linear guide rail 6. An elastic element is provided on the top surface of the first slider 7. The elastic end of the elastic element is connected to the detection wheel 4.

[0056] The first linear guide rail 6 linearly drives the first slider 7, thereby adjusting the position of the detection wheel 4 along the axis of the rubber roller 2. Since the rubber roller 2 has different sizes and different lengths of the rubber layer, it is understandable that the width of the detection wheel 4 is much smaller than the length of the rubber roller 2. The first linear guide rail 6 is used to move the detection wheel 4 to achieve contact detection of the entire rubber roller 2.

[0057] Furthermore, the elastic element includes:

[0058] The base 8 is fixed to the top surface of the first slider 7. The top of the base 8 has a groove, and the number of grooves is the same as that of the detection wheels 4 and they correspond one-to-one.

[0059] The connecting rod 9 is fixed to the inner wall of the bottom end of the groove. A pressure signal instrument 5 is installed on the inner wall of the bottom end of the groove. The bottom end of the connecting rod 9 abuts against the pressure signal instrument 5.

[0060] The card holder 10 is slidably connected in the groove. The bottom end of the card holder 10 is provided with a groove. The connecting rod 9 is slidably connected in the groove. The two ends of the spring 35 are respectively fixed between the top end of the connecting rod 9 and the inner wall of the top end of the groove. A pair of brackets 11 are fixedly connected to the top end of the card holder 10. The detection wheel 4 is rotated between the pair of brackets 11.

[0061] By sliding the card holder 10 into the groove, and fixing the connecting rod 9 into the groove, and sliding the connecting rod 9 into the groove at the bottom of the card holder 10, the groove and the groove are used to limit the card holder 10, ensuring the sliding effect of the card holder 10 and preventing the card holder 10 from getting stuck with the inner wall of the groove.

[0062] Furthermore, the detection wheel 4 is rotated and supported by a pair of brackets 11 fixed on the card holder 10. When the detection wheel 4 rolls in contact with the rubber roller 2, it rotates and bounces when it comes into contact with the deposits on the surface of the rubber roller 2. The pressure is transmitted to the connecting rod 9 by the compression spring 35 through the brackets 11 and the card holder 10. The pressure signal of the connecting rod 9 is detected by the pressure signal instrument 5 to detect the deposits on the surface of the rubber roller 2. The pressure signal instrument 5 can be a common pressure sensor.

[0063] Furthermore, limit posts 12 are fixed to opposite sides of the inner wall of the groove, and limit grooves are formed on the side wall of the card holder 10, with the limit posts 12 and limit grooves corresponding to each other. This makes the sliding of the card holder 10 and the groove more stable, ensuring the accuracy of pressure signal detection by the movement of the detection wheel 4.

[0064] Furthermore, the three-axis drive mechanism includes:

[0065] The second linear guide 13 is fixed on the top surface of the workbench 1. The length direction of the second linear guide 13 is parallel to the axis direction of the rubber roller 2. The second slider 14 is slidably connected on the second linear guide 13.

[0066] The first servo cylinder 15 is fixedly connected to the top surface of the second slider 14. The piston end of the first servo cylinder 15 extends vertically upward and is fixedly connected to a fixed seat 17.

[0067] The second servo cylinder 16 is fixedly connected to one side of the fixed base 17. The piston end of the second servo cylinder 16 passes through the fixed base 17 in the horizontal direction and is fixedly connected to the mounting base 18. The first servo motor 19 is fixedly connected inside the mounting base 18. The output shaft of the first servo motor 19 is fixedly connected to the axis of the grinding wheel 3.

[0068] The second slider 14 is moved by the second linear guide rail 13, and the first servo cylinder 15 drives the fixed seat 17 to rise and fall relative to the second slider 14. At the same time, the second servo cylinder 16 drives the mounting seat 18 to move horizontally relative to the fixed seat 17. By rotatably fixing the grinding wheel 3 on the mounting seat 18, the three-axis displacement adjustment of the grinding wheel 3 is realized. The first servo motor 19 provides driving force to make the grinding wheel 3 rotate and grind the rubber roller 2.

[0069] Furthermore, the visual acquisition components include:

[0070] Mounting plate 20 is fixed to the side wall of the second slider 14. Mounting bracket 21 is fixed to the top surface of mounting plate 20. Support block 22 is fixed to the top of mounting bracket 21. Industrial camera 23 is mounted on the side of support block 22 near detection wheel 4.

[0071] The center of the industrial camera 23 corresponds to the center of the grinding wheel 3 in the vertical direction.

[0072] The center of the inspection wheel 4 is positioned by the industrial camera 23. Combined with the movement of the second slider 14 by the second linear guide 13, the position of the industrial camera 23 is adjusted, and the width of the grinding wheel 3 corresponds to that of the inspection wheel 4, enabling accurate positioning of the grinding wheel 3 and the inspection wheel 4. The industrial camera 23 acquires the image signal of the inspection wheel 4 and transmits it to an external control center. The external control center controls the second linear guide 13 to move the grinding wheel 3, aligning the grinding wheel 3 with the inspection wheel 4. The transmission of the image signal and the driving control principle of the second linear guide 13 are existing technologies and will not be described in detail.

[0073] Similarly, when the industrial camera 23 is mounted on the first slider 7, it can be done by aligning the center of the industrial camera 23 with the center of the detection wheel 4.

[0074] Furthermore, the clamping components include:

[0075] The lifting plate 24 is movably connected to the top surface of the workbench 1. On the side of the lifting plate 24 closest to the grinding wheel 3, there are a first support plate 25 and a second support plate 26 respectively. The first support plate 25 is fixed to the end of the lifting plate 24, and the second support plate 26 is slidably connected to the lifting plate 24. The sides of the first support plate 25 and the second support plate 26 that are close to each other are respectively provided with a three-jaw centripetal mechanism. The two three-jaw centripetal mechanisms are used to clamp the two ends of the rubber roller 2.

[0076] The rubber roller 2 is fixed by a three-jaw centripetal mechanism, and the height of the rubber roller 2 is adjusted by a lifting plate 24 to ensure that rubber rollers 2 of different diameters can roll and contact the detection wheel 4.

[0077] In this technical solution, the three-jaw centripetal mechanism adopts a common three-jaw chuck 27. By fixing the drive motor 28 on the first support plate 25, the output shaft of the drive motor 28 is fixed to the adjacent three-jaw chuck 27 to realize the drive rotation of the three-jaw chuck 27, thereby rotating the rubber roller 2. This is a conventional design for clamping and fixing rubber rollers 2 of different diameters, and will not be described in detail.

[0078] Furthermore, it also includes:

[0079] The second servo motor 29 is fixedly connected to the side of the lifting plate 24 away from the first support plate 25. The side wall of the lifting plate 24 is provided with a sliding groove, and a screw 30 is rotated in the sliding groove. The output shaft of the second servo motor 29 is coaxially fixedly connected to the screw 30.

[0080] The movable block 31 is threaded onto the screw 30, slides in the groove, and its side wall is fixedly connected to the second support plate 26.

[0081] The third servo cylinder 32 is fixedly connected to the top surface of the worktable 1, and the piston end of the third servo cylinder 32 is fixedly connected to the lifting plate 24 vertically upward.

[0082] The second servo motor 29 drives the screw 30 to rotate, causing the second support plate 26 to slide toward the first support plate 25. The three-jaw chuck 27 on the first support plate 25 and the second support plate 26 clamps and fixes both ends of the rubber roller 2. The lifting plate 24 is raised and lowered by the third servo cylinder 32.

[0083] In this technical solution, slots are provided on both sides of the lifting plate 24, and a guide rod 33 is fixedly connected to the top surface of the workbench 1. The top end of the guide rod 33 slides in the slot, which improves the stability of the lifting plate 24.

[0084] Furthermore, a guide plate 34 is fixedly connected to the top surface of the workbench 1. A bevel is provided on one side of the guide plate 34, and the top of the bevel corresponds to the axis of the rubber roller 2 in the vertical direction. The bevel extends downward at an angle away from the rubber roller 2. The first linear guide rail 6 is installed on the side of the guide plate 34 away from the bevel.

[0085] In this technical solution, the guide plate 34 is positioned at the center of the rubber roller 2, i.e., the vertical line of the three-jaw chuck 27, so that when clamping and fixing rubber rollers 2 of different sizes, the top of the guide plate 34 can be kept at the center of the rubber roller 2. The first linear guide rail 6 is fixed on one side of the guide plate 34, so that the detection wheel 4 can contact the outer wall of the rubber roller 2 in the vertical direction. After the grinding wheel 3 rolls and contacts the rubber roller 2 to grind off the attached material, it can be guided and discharged through the guide plate 34, which is convenient for cleaning impurities. Specifically, there can be two guide plates 34, which are distributed between the first linear guide rail 6 and the second linear guide rail 13.

[0086] This invention provides a working principle for a rubber roller grinding device:

[0087] The surface of the rubber roller 2 is pre-ground by the grinding wheel 3. Then, the screw 30 is rotated by the second servo motor 29 to control the second support plate 26 to move toward the first support plate 25. The two- or three-jaw chuck 27 clamps and fixes both ends of the rubber roller 2. The height of the rubber roller 2 is adjusted by the third servo cylinder 32 so that the rubber roller 2 contacts several detection wheels 4 and squeezes the chuck 10 into the groove. At this time, the pressure of several pressure signal instruments 5 is kept consistent. If the pressure signals are inconsistent, the rubber roller 2 is rotated until the pressure signals are consistent. The pressure signal at this moment is set as the initial value, and then the drive is started. The motor 28 rotates the rubber roller 2. During the rotation of the rubber roller 2, the surface of the rubber roller 2 is detected by the detection wheel 4. When a jumping pressure signal is generated, the second slider 14 is moved by the second linear guide 13. The position of the detection wheel 4 is obtained by the industrial camera 23, so that the position of the grinding wheel 3 corresponds to that of the detection wheel 4. The first servo cylinder 15 and the second servo cylinder 16 cooperate to make the grinding wheel 3 roll and contact the rubber roller 2, thereby performing secondary grinding on the area with the attached material on the surface of the rubber roller 2 until the pressure signal detected by the detection wheel 4 is consistent with the pressure signal on the adjacent detection wheel 4.

[0088] The detection wheel 4 is moved along the axis of the rubber roller 2 by the first linear guide 6. When the pressure signal transmitted on the detection wheel 4 causes a jump change, the above steps are repeated so that the grinding wheel 3 follows the position of the detection wheel 4 to perform repeated grinding until the detection wheel 4 passes through the area covered by the rubber layer on the outer periphery of the rubber roller 2. This completes the grinding of the rubber roller 2 and effectively improves the grinding effect of the rubber roller 2.
