Description

Technical Field

[0001] The invention relates to the technical field of rubber roller grinding, in particular to a surface grinding device for a rubber roller of a spinning machine. Background Art

[0002] Spinning machine rubber roller is a rubber roller used in the drafting mechanism of spinning machinery. It is an important drafting component in the spinning process. It is mainly a roll-shaped product made of metal core and rubber coating through vulcanization. It plays a key drafting role in the spinning process, and together with other components such as cradle, upper and lower pins, rollers, spindles, steel collars and their process parameters, it affects the spinning performance of the drafting mechanism. In the production process of rubber rollers, when the metal roller used as the roller core is produced, in order to ensure its surface smoothness, it is generally polished and repaired, so that the outer rubber coating and the metal core can fit perfectly. The common grinding and repairing method is mostly to manually place a rubber roller core on a grinding table, and then use a handheld grinder or an automatic grinder to grind and trim it, and finally obtain a fine rubber roller metal core.

[0003] However, in actual operation, it was found that due to the large number of metal cores in the production process, only one metal core can be processed each time during grinding and trimming, resulting in low grinding efficiency. In addition, in the grinding process, rough grinding is required first, and then fine grinding is performed after the rough grinding is completed. The purpose of rough grinding is to reduce the surface temperature of the rubber roller and ensure the cylindricity of the rubber roller surface, and the purpose of fine grinding is to ensure the stability and precision of the rubber roller. However, in actual operation, rough grinding is performed manually using a coarse grinding wheel first, and then fine grinding is performed using a fine grinding wheel. The process is complicated and manual operation is slow, which not only has low precision, but also further slows down work efficiency.

[0004] Therefore, it is necessary to provide a spinning machine rubber roller surface grinding device to solve the above-mentioned technical problems. Summary of the invention

[0041] Each grinding mechanism includes a hollow rectangular seat 34, which is fixedly mounted on the joint block 35, and a transfer rod 36 is rotatably mounted in the hollow rectangular seat 34. A fourth servo motor is fixedly mounted on the outer wall of one side of the hollow rectangular seat 34, and its output shaft is fixedly connected to one end of the transfer rod 36, and a second gear 37 is fixedly sleeved on the transfer rod 36.

Two guide rods 40 are slidably mounted on the side of the hollow rectangular seat 34 away from the hollow cylinder 28. The cross-section of the guide rod 40 is square, which can ensure that the first toothed bar 38 and the second toothed bar 39 can only perform linear motion and will not rotate. The two guide rods 40 are arranged One end of the guide rod 40 located in the hollow rectangular seat 34 is fixedly connected to the second toothed bar 39 and the first toothed bar 38 respectively, and one end of the two guide rods 40 located outside the hollow rectangular seat 34 is fixedly installed with a first drive motor 41 and a second drive motor 43 respectively, the first drive motor 41 is located above the second drive motor 43, and a rough grinding wheel 42 is fixedly installed on the output shaft of the first drive motor 41, and a fine grinding wheel 44 is fixedly installed on the output shaft of the second drive motor 43. In the initial state, the rough grinding wheel 42 protrudes from the fine grinding wheel 44, so that the rough grinding wheel 42 can contact the rubber roller body 201 first, so that rough grinding can be performed first, and then when the rough grinding is completed, the fourth servo motor is started, so that the rough grinding wheel 42 and the fine grinding wheel 44 are alternately rotated, so that the fine grinding wheel 44 protrudes from the rough grinding wheel 42, so that the rough-ground rubber roller body 201 can be finely ground;

[0042] And a lateral support plate 22 is fixedly installed on the top of the support base 1. An elevating mechanism is provided on the lateral support plate 22 to drive the grinding mechanism to perform lifting and grinding.

[0043] The elevating mechanism includes a transverse connecting platform 23 which is fixedly installed on one side of the lateral support plate 22 close to the support disk 4. An adjusting tooth column 24 is movably arranged on the transverse connecting platform 23. The bottom of the adjusting tooth column 24 is fixedly installed with an adapter frame 27. The bottom of the adapter frame 27 is fixedly connected with a hollow cylinder 28. A first servo motor 25 is fixedly installed on the top of the transverse connecting platform 23. A first gear 26 is fixedly sleeved on the output shaft thereof. The first gear 26 meshes with the adjusting tooth column 24. By operating the first servo motor 25 and using the meshing between the first gear 26 and the adjusting tooth column 24, the grinding mechanism can be driven to perform lifting adjustment, so as to be able to grind various parts of the rubber roller main body 201. In addition, two guiding columns are slidably installed on the transverse connecting platform 23. The bottom ends of the two guiding columns are both fixed to the adapter frame 27 to ensure that the hollow cylinder 28 can only perform linear lifting.

[0044] And in this mode, in order to improve the supporting strength of the rotating shaft 7, a plurality of reinforcing folded plates are fixedly installed on the top of the support disk 4. A plurality of rotating shafts 7 respectively penetrate through the plurality of reinforcing folded plates and are rotatably connected with the corresponding reinforcing folded plates.

[0045] In this mode, in order to ensure that the hollow rectangular seat 34 can only perform linear motion, a connecting frame rod 32 is fixedly installed at the bottom of the hollow cylinder 28. The connecting frame rod 32 is formed by welding three long rods distributed in an annular array, and the centers of the three long rods are the same point. A plurality of sliding seats 33 are slidably installed on the connecting frame rod 32. The tops of the plurality of sliding seats 33 are respectively fixedly connected with the plurality of hollow rectangular seats 34.

[0046] In this mode, in order to form a stable support for the rubber roller assembly 2 and enable it to rotate stably, a plurality of U-shaped fixing frames 17 are fixedly installed on the top of the grinding table 6. Telescopic cylinders 18 are fixedly installed on the inner walls of both sides of the plurality of U-shaped fixing frames 17. Fixed clamping pieces 19 are fixedly installed on the output shafts of the plurality of telescopic cylinders 18. Arc-shaped clamping pieces 20 are fixedly installed on the output shafts of the plurality of fixed clamping pieces 19. A plurality of rubber roller transmission rods 202 respectively pass through the corresponding two arc-shaped clamping pieces 20. A plurality of balls 21 are embedded on the inner walls of the plurality of arc-shaped clamping pieces 20, and the rubber roller transmission rods 202 are in contact with the balls 21. In this way, it can be ensured that when the output shaft of the telescopic cylinder 18 extends, due to the rolling action of the balls 21, it will still not affect the rotation of the rubber roller transmission rod 202. And, reinforcing support heads are fixedly installed on the tops of the plurality of arc-shaped clamping pieces 20. The tops of the plurality of reinforcing support heads are respectively in contact with the bottom end faces of the corresponding rubber roller main bodies 201.

[0047] In this embodiment

[0048] When the rubber roller body 201 needs to be repaired, the output shafts of the multiple telescopic cylinders 18 are first started to extend, so that a shuttle hole is formed between the corresponding two arc-shaped clamping pieces 20, and then the multiple rubber roller assemblies 2 are taken out, and the multiple rubber roller assemblies 2 are passed through the corresponding arc-shaped clamping pieces 20, and respectively inserted into the multiple connection frames 8 and contact with the corresponding contact heads 9, and then the multiple bidirectional screws 11 are rotated in sequence, and finally the arc-shaped clamping piece 13 tightly clamps the rubber roller transmission rod 202, and then the multiple telescopic cylinders 18 are started. At this time, the rubber roller assembly 2 forms a stable clamping effect under the support of the two arc-shaped clamping pieces 13 and the balls 21 in the two arc-shaped clamping pieces 20;

[0049] Then, the second servo motor is started in the positive direction, and its output shaft drives the vertical screw 29 to rotate, and the lifting seat 30 starts to descend linearly. With the bottom of the lifting seat 30 and the joint of the articulated arm 31, and at the same time, limited by the horizontal sliding limit of the sliding seat 33, the multiple hollow rectangular seats 34 move linearly in a direction away from the hollow cylinder 28, and finally make the multiple rough grinding wheels 42 contact with the corresponding rubber roller body 201, and then start the multiple first drive motors 41, so that the multiple rough grinding wheels 42 start to rotate. At the same time, the output shaft of the third servo motor is started to rotate slowly, and through the meshing of the third gear and the fourth gear, the corresponding rotating shaft 7 starts to rotate. At the same time, through the joint action of the synchronous wheel 15 and the synchronous belt 16, the multiple rotating shafts 7 rotate at the same time, and then can drive the multiple rubber roller assemblies 2 to rotate. At this time, with the rotation of the rubber roller assembly 2, the uniformly rotating rough grinding wheel 42 will form a grinding process for the circle in contact with the rubber roller body 201;

[0050] After a circle of grinding is formed on a height of the rubber roller body 201, the first servo motor 25 can be started in the positive direction, and its output shaft drives the first gear 26 to rotate. At this time, the first gear 26 is meshed with the adjusting tooth column 24. When the adjusting tooth column 24 drops a tooth height, the first servo motor 25 is turned off. At this time, the rough grinding wheel 42 sinks a distance on the rubber roller body 201, and can grind a circle of the rubber roller body 201 at the height. When the circle is polished again, the rough grinding wheel 42 is continued to sink a distance in the above manner, and the process is repeated until the rough grinding wheel 42 drops to the bottom of the rubber roller body 201, and the rough grinding stage of multiple rubber roller bodies 201 is completed.

[0051] Then, the plurality of fourth servo motors are started in the positive direction, and the output shafts of the plurality of fourth servo motors drive the corresponding transfer rods 36 to rotate, and then the corresponding second gears 37 can be driven to rotate. At this time, the first toothed bars 38 and the second toothed bars 39 located above and below the second gears 37 start to make opposite movements, and the coarse grinding wheel 42 gradually moves away from the rubber roller body 201, while the fine grinding wheel 44 gradually approaches the rubber roller body 201, until the fine grinding wheel 44 contacts the rubber roller body 201, and then the second driving motor 43 is started to start fine grinding of the rubber roller body 201. After one round of fine grinding is completed, the first servo motor 25 can be started in the reverse direction, and the first servo motor 25 is turned off every time the tooth column 24 rises a tooth height, and at this time, the fine grinding wheel 44 rises a small height, so that it can be moved to the part that has not been finely ground for grinding, and then it is reciprocated until the fine grinding wheel 44 moves to the top of the rubber roller body 201, and at this time, all the grinding work on the rubber roller body 201 is completed;

[0052] Subsequently, multiple bidirectional screws 11 are screwed, and the output shafts of multiple telescopic cylinders 18 are started to retract, and the multiple rubber roller assemblies 2 are loosened and taken out. Then, multiple rubber roller assemblies 2 that have not been polished are taken out again for installation, and the double polishing work of rough grinding and fine grinding can be continued.

[0053] Compared with the related art, the spinning machine rubber roller surface grinding device provided by the present invention has the following beneficial effects:

The fixed sleeve is provided with a steering seat 48, a finger cylinder 49 is fixedly installed at the bottom of the steering seat 48, and a V-shaped clamp block 50 is fixedly installed on the two clamping arms of the finger cylinder 49. The V-shaped clamp block 50 is adapted to the rubber roller assembly 2. A feeder assembly 58 is provided below the finger cylinder 49. The feeder assembly 58 is a common feeding device on the market, which can continuously transport the rubber roller assembly 2 to be polished. A fixed plate 51 is fixedly installed on one side of the cross-joining table 23. The top of the fixed plate 51 A connecting platform 52 is fixedly installed, a rodless cylinder 53 is fixedly installed on the top of the connecting platform 52, a connecting folding plate 54 is fixedly installed on the slider of the rodless cylinder 53, the connecting folding plate 54 passes through the connecting platform 52 and is slidably connected to the connecting platform 52, a horizontal plate 55 is fixedly installed on one side of the connecting folding plate 54, an internal threaded sleeve 56 is rotatably installed on the horizontal plate 55, and a lifting screw 57 is installed on the internal thread of the internal threaded sleeve 56, and the bottom end of the lifting screw 57 is fixedly connected to the U-shaped frame 46;

[0059] In addition, two positioning columns are slidably installed on the cross plate 55, and the bottom ends of the two positioning columns are fixed to the U-shaped frame 46.

[0060] In this embodiment

[0061] When in use, it needs to be used in conjunction with an external feeder assembly 58;

[0062] When it is necessary to place the rubber roller assembly 2 on the grinding turntable 6, in order to improve the degree of automation, the seventh servo motor can be started forward first. Through the meshing of two bevel gears, the internal thread sleeve 56 starts to rotate, and then the lifting lead screw 57 can be driven to descend. During the descending process, when the two V-shaped clamping blocks 50 descend to both sides of the rubber roller assembly 2 on the feeder assembly 58, the seventh servo motor is turned off. Immediately, the finger cylinder 49 is started, and the rubber roller assembly 2 can be clamped by the two V-shaped clamping blocks 50. Subsequently, the seventh servo motor is started in reverse to bring the finger cylinder 49 and the U-shaped frame 46 back to the original height position;

[0063] Then, the fifth servo motor is started forward. Its output shaft drives the linkage rod 47 to rotate. When the linkage rod 47 drives the swivel base 48 to rotate 90°, the fifth servo motor is turned off. At this time, the rubber roller assembly 2 is in a vertical state. Immediately, the rodless cylinder 53 is started, and the slider on it drives the connecting folding plate 54 to move horizontally. Finally, the clamped rubber roller assembly 2 is positioned above one set of arc-shaped clamping pieces 20. Subsequently, the seventh servo motor is started in reverse, and the clamped rubber roller assembly 2 starts to descend until it descends into the corresponding connecting frame 8 and contacts the abutting head 9. Then, the finger cylinder 49 can be started to release the rubber roller assembly 2. Immediately, the corresponding bidirectional screw 11 is rotated, and the output shaft of the corresponding telescopic cylinder 18 is extended to fix the rubber roller assembly 2;

[0064] Subsequently, the above steps are operated in reverse. First, the finger cylinder 49 is brought back to the original position. Then, the sixth servo motor is started forward. Through the meshing of the fifth gear and the sixth gear, the bearing column 45 drives the U-shaped base 3 to rotate. When the multiple U-shaped fixing frames 17 on the grinding turntable 6 are alternated, the sixth servo motor can be turned off. Then, continue to clamp and install another rubber roller assembly 2 in the same way as above until all the rubber roller assemblies 2 on the grinding turntable 6 are installed, and then the grinding work can be carried out;

[0065] After a batch of rubber roller assemblies 2 are ground, by starting the sixth servo motor in reverse to make the grinding turntable 6 rotate in the reverse direction, the next batch of multiple rubber roller assemblies 2 can be reloaded. In this way, each time a rubber roller assembly 2 is loaded, the grinding turntable 6 is rotated in the opposite direction to the previous time to prevent the cables on the grinding turntable 6 from getting entangled.

[0066] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
