Description

Technical Field

[0001] The present invention relates to the technical field of rubber rollers, and more particularly to a rubber roller structure. Background Art

[0002] A rubber roller is a roll-shaped product made of metal or other materials as the core and rubber covered by vulcanization. Rubber rollers are widely used in various industrial fields, such as papermaking, dyeing and printing, etc. The internal bearing and shaft head structure are very precise. Poor lubrication will cause wear and affect the quality of use. Rubber rollers can be classified according to different classification standards: papermaking rubber rollers, dyeing and printing rubber rollers, printing rubber rollers, metallurgical rubber rollers, etc. Rubber rollers are often scratched or bruised by foreign objects during use. If they continue to be used, it will inevitably affect the quality of the product. The traditional solution requires re-wrapping, but the operation is more cumbersome. With the development of technology, polymer composite materials are often used to solve the problem of surface damage of rubber rollers. Because the material has excellent adhesion, wear resistance and tensile strength, different repair materials can be selected according to the different surface hardness of the rubber roller to achieve disassembly-free repair. The repair cost is lower and the time is shorter than the traditional method.

[0003] When the existing rubber roller is used, when scratches or bruises appear on the surface of the rubber roller, a repair material is used to repair the scratches or bruises on the surface of the rubber roller, so that the rubber roller can be reused. However, when the scratches or bruises on the surface of the rubber roller are large in scope, the repair effect of the repair material on the surface of the rubber roller is poor. At this time, the rubber roller needs to be disassembled from the processing equipment and replaced. However, when the rubber roller is disassembled, the processing equipment needs to open the fixed positions of the two ends of the rubber roller, and then the entire rubber roller needs to be disassembled from the processing equipment, which takes a lot of time, reduces the working efficiency of the processing equipment, and thus reduces the practicality of the rubber roller.

[0040] See also Figures 1 to 11 A rubber roller structure, comprising a roller core 1, wherein the outer circumferential surface of the roller core 1 is fixedly connected to a rubber coating layer 2, both ends of the roller core 1 are provided with a fixed shaft 3, a loading and unloading assembly 4 is provided between the fixed shaft 3 and the roller core 1, and the loading and unloading assembly 4 comprises mounting holes 41 opened at the center positions of both ends of the outer surface of the roller core 1, and a No. 1 docking block 42 is fixedly connected to the center position of one side of the inner wall of the mounting hole 41;

[0041] One end of the fixed shaft 3 close to the No. 1 docking block 42 is fixedly connected to the No. 2 docking block 43, and the outer circular surface of the fixed shaft 3 is slidably connected to a connecting tube 44, and the inner diameter of the connecting tube 44 is larger than the outer diameter of the No. 2 docking block 43. The inner circular surface of the mounting hole 41 is provided with an internal thread 46, and the outer circular surface of the connecting tube 44 is provided with an external thread 45 on one side close to the mounting hole 41, and the external thread 45 is threadedly connected to the internal thread 46.

[0043] like Figure 3 As shown, the outer circumferential surface of the sleeve 47 is fixedly connected with five evenly distributed No. 1 limiting rings 412 , and the inner circumferential surface of the connecting tube 44 is provided with five evenly distributed limiting grooves 413 , and the No. 1 limiting rings 412 are rotatably connected with the limiting grooves 413 .

[0044] like Figure 3 As shown, six evenly distributed grooves 414 are formed on the side of the outer circumferential surface of the connecting tube 44 away from the external thread 45, and the six grooves 414 are hexagonal in shape as a whole.

[0045] When the rubber roller is in use, the fixed shafts 3 at both ends are fixed to the processing equipment, thereby installing the rubber roller in the processing equipment. However, when a large range of damage appears on the surface of the rubber coating 2, the rubber roller needs to be removed from the processing equipment for replacement. However, when the rubber roller is removed, the processing equipment needs to open the positions where the two ends of the rubber roller are fixed, and then the entire rubber roller needs to be removed from the processing equipment, which takes a lot of time, reduces the working efficiency of the processing equipment, and thus reduces the practicality of the rubber roller. Therefore, a loading and unloading assembly 4 is provided. When the rubber roller needs to be removed, the connecting tube 44 is first manually rotated, and then the connecting tube 44 is screwed out from the mounting hole 41 through the threaded connection between the external thread 45 and the internal thread 46, so that the connecting tube 44 is separated from the roller core 1, and the No. 1 docking block 42 is separated from the No. 2 docking block 43 at the same time, so that the roller core 1 with the damaged rubber coating 2 can be taken out from between the two fixed shafts 3, so that the roller core 1 can be quickly taken out from the processing equipment, and then the new roller core 1 is placed between the two fixed shafts 3, and the No. 1 docking block 42 is aligned with the No. 2 docking block 43, so that the No. 1 connecting groove 48 and the No. 2 connecting rod 410 on the No. 1 docking block 42 are aligned with the No. 1 connecting groove 48 and the No. 2 connecting rod 410 on the No. 2 docking block 43. 410 are aligned with each other, and then the connecting tube 44 is moved to drive the sleeve 47 to move, so that the No. 2 connecting groove 411 in the sleeve 47 is slidably connected with the No. 2 connecting rod 410, and at the same time, the No. 1 connecting rod 49 in the sleeve 47 is slidably connected with the No. 1 connecting groove 48, so that the No. 1 docking block 42 and the No. 2 docking block 43 can be better aligned, and at the same time, the No. 1 docking block 42 and the No. 2 docking block 43 can rotate synchronously, and then the connecting tube 44 is rotated, and the external thread 45 is screwed into the internal thread 46, so that the connecting tube 44 is fixedly connected with the roller core 1, so that the new roller core 1 is installed between the two fixed shafts 3, and then the new roller core 1 can be quickly replaced with the roller core 1 with the damaged rubber layer 2, which improves the practicality of the rubber roller. And through the six hexagonal grooves 414, the connecting tube 44 can be rotated with a wrench, and at the same time, the No. 1 limiting ring 412 is rotatably connected with the limiting groove 413, which can facilitate the rotation of the connecting tube 44.

[0046] like Figure 3 , Figure 4 , Figure 5As shown, a locking assembly 5 is arranged between the connecting cylinder 44 and the roller core 1, and the locking assembly 5 includes annular grooves 51 provided on the outer sides of both ends of the outer surface of the roller core 1, an annular block 52 is fixedly connected to a position corresponding to the annular groove 51 on one side of the outer surface of the connecting cylinder 44, a ratchet tooth groove 53 is provided on the inner side of the inner circumferential surface of the annular groove 51, and four evenly distributed No. 1 slide grooves 54 are provided on the inner circumferential surface of the annular block 52, and a No. 1 slider 55 is slidably connected inside the four No. 1 slide grooves 54, and a ratchet tooth 56 is fixedly connected on the side of the outer surface of the four No. 1 sliders 55 close to the ratchet tooth groove 53, and two No. 1 positioning holes 57 are provided on the side of the outer surface of the No. 1 slider 55 away from the ratchet tooth 56, and a No. 1 spring 58 is provided inside the two No. 1 positioning holes 57.

[0047] like Figure 4 , Figure 5 As shown, a No. 2 slide groove 59 is provided on the inner wall of the four No. 1 slide grooves 54 on the side away from the roller core 1, a slide plate 510 is fixedly connected to the outer surface of the four No. 1 sliders 55 on one side, and the slide plate 510 is slidably connected to the No. 2 slide groove 59, an arcuate slide groove 511 is provided on the inner wall of the four No. 2 slide grooves 59 on the side away from the No. 1 slide groove 54, an arcuate slider 512 is slidably connected inside the arcuate slide groove 511 and located below the slide plate 510, a connecting block 513 is fixedly connected to the outer surface of the four arcuate sliders 512 on the side away from the No. 1 slider 55, and one end of the four connecting blocks 513 passes through the connecting tube 44 and is commonly fixedly connected to an annular rotating block 514, and an anti-slip groove 515 is provided on the outer circumferential surface of the annular rotating block 514.

[0048] In the above embodiment, the external thread 45 provided on the outer circumferential surface of the connecting tube 44 is threadedly connected with the internal thread 46 provided on the inner circumferential surface of the mounting hole 41, so that the roller core 1 with the rubber coating 2 can be taken out from between the two fixed shafts 3, and then the new roller core 1 and the roller core 1 with damaged rubber coating 2 can be quickly replaced, thereby improving the practicality of the rubber roller. However, because the connecting tube 44 is threadedly connected with the mounting hole 41, and the rubber roller rotates during use, it is easy to cause the connecting tube 44 and the mounting hole 41 to loosen, reducing the fixing effect between the connecting tube 44 and the mounting hole 41, making the fixing effect between the roller core 1 and the two fixed shafts 3 poor, thereby reducing the practicality of the rubber roller. Therefore, a locking component 5 is provided. When the connecting tube 44 is screwed into the mounting hole 41, the annular block 52 is simultaneously inserted into the annular groove 51, and then the No. 1 spring 58 inside the No. 1 positioning hole 57 drives the No. 1 slider 55 to move toward the ratchet tooth groove 53. The ratchet teeth 56 are driven to move toward the ratchet tooth groove 53, so that the ratchet teeth 56 are engaged with the ratchet tooth groove 53, thereby preventing the connecting tube 44 from driving the annular block 52 to rotate in the opposite direction, and further preventing the connecting tube 44 from being screwed out of the mounting hole 41, thereby improving the fixing effect between the roller core 1 and the two fixed shafts 3, thereby improving the practicality of the rubber roller. At the same time, the connecting block 513 is driven to rotate by rotating the annular rotating block 514, and at the same time, the arc sliding block 512 is driven to move inside the arc sliding groove 511, thereby driving the slide plate 510 to move upward in the second sliding groove 59, and at the same time driving the first sliding block 55 to move upward, thereby driving the ratchet teeth 56 to move away from the ratchet tooth groove 53, so that the ratchet teeth 56 are separated from the ratchet tooth groove 53, thereby allowing the connecting tube 44 to drive the annular block 52 to rotate in the opposite direction, thereby facilitating the removal of the roller core 1 from between the two fixed shafts 3, and the annular rotating block 514 can be easily rotated through the anti-slip groove 515.

[0049] like Figure 4 , Figure 5 , Figure 6 As shown, a fixing component 6 is provided at the upper end of the inner wall of the arc-shaped slide groove 511, and the fixing component 6 includes a No. 3 slide groove 64 opened at a position above the upper end of the inner wall of the arc-shaped slide groove 511 above the slide plate 510, and a No. 2 slider 65 is slidably connected inside the No. 3 slide groove 64, and a fixing rod 66 is fixedly connected to the outer surface of the No. 2 slider 65 on the side close to the slide plate 510, and a through hole 63 is opened at a position corresponding to the fixing rod 66 on the outer surface of the slide plate 510, and a U-shaped slider 61 is slidably connected to one side of the inner wall of the arc-shaped slide groove 511, and the U-shaped slider 61 is fixedly connected to the arc-shaped slider 512, and a fixing hole 62 is opened on one side of the outer surface of the U-shaped slider 61, and a threaded hole 67 is opened on the outer surface of the No. 2 slider 65 on the side away from the fixing rod 66, and the threaded hole 67 extends to the inside of the fixing rod 66, and a threaded rod 68 is threadedly connected to the inside of the threaded hole 67, and one end of the threaded rod 68 passes through the connecting tube 44 and is fixedly connected to a rotating block 69.

[0050] In the above embodiment, the ratchet teeth 56 are driven to move toward the ratchet tooth groove 53 by the first spring 58, so that the ratchet teeth 56 are engaged with the ratchet tooth groove 53, thereby preventing the connecting cylinder 44 from rotating in the opposite direction, and further preventing the connecting cylinder 44 from being screwed out of the mounting hole 41. However, because the rubber roller rotates itself when in use, the ratchet teeth 56 have a certain centrifugal force, so that the ratchet teeth 56 are easily separated from the ratchet tooth groove 53. Therefore, a fixing component 6 is provided. When the annular block 52 is inserted into the annular groove 51, the annular rotating block 514 is rotated in the opposite direction to drive the U-shaped slider 61 to move toward the slide plate 510, so that the U-shaped slider 61 The slide plate 510 is engaged, thereby preventing the slide plate 510 from moving, and further preventing the ratchet teeth 56 from separating from the ratchet tooth grooves 53, thereby improving the use effect of the locking assembly 5; and then because of the hexagonal grooves on the outer surface of the rotating block 69, the rotating block 69 can be rotated by an Allen wrench to drive the threaded rod 68, and then the threaded rod 68 is threadedly connected to the threaded hole 67, thereby driving the second slider 65 and the fixed rod 66 to move, so that the fixed rod 66 passes through the fixing hole 62 and the through hole 63, thereby fixing the U-shaped slider 61 to the slide plate 510, thereby preventing the U-shaped slider 61 from moving, and further improving the use effect of the locking assembly 5.

[0051] like Figure 3 , Figure 7 , Figure 8 As shown, an alignment component 7 is arranged between the No. 1 docking block 42 and the No. 2 docking block 43, and the alignment component 7 includes a circular ring slide groove 71 opened at one end of the outer surface of the two No. 1 docking blocks 42, and the circular ring slide groove 71 extends into the roller core 1, and the two circular ring slide grooves 71 are slidably connected with slide cylinders 72 inside, and the two slide cylinders 72 are fixedly connected with No. 2 limiting rings 73 at one end away from the No. 2 docking block 43, and the outer surfaces of the two No. 2 docking blocks 43 are close to the No. 1 docking block 42. Circular grooves 74 are opened at one end, and four evenly distributed No. 2 positioning holes 75 are opened on one side of the outer surface of the No. 2 limiting ring 73, and No. 2 springs 76 are arranged inside the four No. 2 positioning holes 75.

[0052] like Figure 8 As shown, the inside of the annular groove 74 is slidably connected with a push ring 77, the outer side of the inner circular surface of the annular groove 74 is provided with two No. 4 slide grooves 78, the outer circular surface of the push ring 77 is fixedly connected with two No. 3 sliders 79, and the No. 3 sliders 79 are slidably connected to the No. 4 slide groove 78, one end of the two No. 3 sliders 79 are fixedly connected with a sliding cover 711, the outer circular surface of the No. 2 docking block 43 and the positions corresponding to the two sliding covers 711 are provided with No. 5 slide grooves 710, and the sliding covers 711 are slidably connected to the No. 5 slide grooves 710.

[0053] In the above embodiment, the external thread 45 provided on the outer circumferential surface of the connecting tube 44 is threadedly connected with the internal thread 46 provided on the inner circumferential surface of the mounting hole 41, so that the roller core 1 can be taken out from between the two fixed shafts 3, so that the roller core 1 between the two fixed shafts 3 can be quickly replaced, thereby improving the practicality of the rubber roller. However, when the roller core 1 is installed on the two fixed shafts 3, it is necessary to constantly align the No. 1 docking block 42 with the No. 2 docking block 43 manually, which takes a lot of time and reduces the use effect of the loading and unloading component 4. Therefore, an alignment component 7 is provided. When the roller core 1 is placed between the two fixed shafts 3, the No. 2 limit ring 73 is driven to move out of the annular slide groove 71 by the No. 2 spring 76 in the No. 2 positioning hole 75, thereby driving the slide cylinder 72 to move out of the annular slide groove 71, so that the slide cylinder 72 It is inserted into the annular groove 74, thereby fixing the No. 1 docking block 42 and the No. 2 docking block 43, and then the No. 1 docking block 42 and the No. 2 docking block 43 can be automatically aligned without spending a lot of time. The No. 1 docking block 42 and the No. 2 docking block 43 are manually aligned, which improves the use effect of the loading and unloading component 4, and the outer cylindrical surface of one end of the slide cylinder 72 is an inclined surface, so that the roller core 1 can be better placed between the two fixed shafts 3, and then the slide cover 711 in the No. 5 slide groove 710 is manually pushed to move, thereby driving the No. 3 slider 79 to move in the No. 4 slide groove 78, and at the same time driving the push ring 77 to move outside the annular groove 74, thereby pushing the slide cylinder 72 to move, so that the slide cylinder 72 is pushed out of the annular groove 74, thereby facilitating the separation of the No. 1 docking block 42 and the No. 2 docking block 43.

[0054] like Figure 8 , Fig. 9 , Fig.10 As shown, a synchronization component 8 is arranged between the two No. 2 limiting rings 73, the inner circumferential surfaces of the two No. 2 limiting rings 73 are fixedly connected with a cross-shaped slider 82, the inner side of the inner circumferential surface of the two annular slide grooves 71 is provided with a cross-shaped slide groove 81 at a position corresponding to the cross-shaped slider 82, and the cross-shaped slider 82 is slidably connected to the cross-shaped slide groove 81, and the inner walls of the two cross-shaped slide grooves 81 are provided with a No. 6 slide groove 83 on one side close to each other, and the outer surface of the two cross-shaped sliders 82 is fixedly connected with a slide rod 84 on one side, and the slide rod 84 is slidably connected to the No. 6 slide groove 8 3 sliding connection, the inner surfaces of the two No. 6 slide grooves 83 are each provided with an L-shaped slide groove 85 at one end close to each other, the one end of the two slide bars 84 is fixedly connected with a No. 4 slider 86, and the No. 4 slider 86 is slidingly connected to the L-shaped slide groove 85, the outer surfaces of the two No. 4 sliders 86 are each fixedly connected with a rack 87 at one side close to each other, and the positions of the two racks 87 are staggered, and a connecting groove 88 is provided between the two L-shaped slide grooves 85, a gear 89 is rotatably connected inside the connecting groove 88, and the two racks 87 are meshed with the gear 89.

[0055] The push ring 77 is driven by the sliding cover 711 to move, thereby pushing the slide cylinder 72 out of the annular groove 74, so as to facilitate the separation of the No. 1 docking block 42 and the No. 2 docking block 43. However, the No. 1 docking block 42 and the No. 2 docking block 43 have two groups, and the sliding covers 711 on both sides need to be pushed at the same time to drive the push rings 77 on both sides, and at the same time, the slide cylinders 72 on both sides are pushed out of the annular groove 74, which reduces the use effect of the alignment component 7. Therefore, a synchronization component 8 is provided. When the slide cylinder 72 on one side is pushed out of the annular groove 74 and moves into the annular slide groove 71, it drives one side to move out of the annular groove 74. The cross-shaped slider 82 on one side moves into the cross-shaped slide groove 81, thereby driving the slide bar 84 on one side to move into the sixth slide groove 83, and then driving the fourth slider 86 on one side to move into the L-shaped slide groove 85, and at the same time driving the rack 87 on one side to move, thereby driving the gear 89 to rotate in the connecting groove 88, and then driving the rack 87 on the other side to move in the opposite direction, so that the two racks 87 move close to each other at the same time, thereby driving the two slide cylinders 72 to move into the circular slide groove 71 at the same time, and then the slide cylinders 72 on both sides can be pushed out of the circular groove 74 at the same time, thereby improving the use effect of the alignment component 7.

[0056] Instructions for use: When the rubber coating 2 fixed on the outer surface of the roller core 1 is damaged to a large extent, first start the fixing assembly 6, pull the fixing rod 66 out of the fixing hole 62 and the through hole 63, so as to release the fixing of the slide plate 510, then rotate the annular rotating block 514 to drive the arc-shaped sliding block 512 to move, thereby driving the ratchet teeth 56 to move away from the ratchet tooth groove 53, so that the ratchet teeth 56 are separated from the ratchet tooth groove 53, and then rotate the connecting cylinder 44 to screw the connecting cylinder 44 out of the mounting hole 41, so that The connecting cylinder 44 is separated from the roller core 1, and then the connecting cylinder 44 is moved to make the connecting cylinder 44 away from the No. 2 docking block 43, and then the sliding cover 711 is manually pushed to drive the pushing ring 77 to move, thereby pushing the slide cylinder 72 out of the circular groove 74, so that the slide cylinder 72 moves to the circular groove 71, and at the same time, the synchronization component 8 is started to move the slide cylinders 72 on both sides to the circular groove 71 at the same time, and then the roller core 1 is removed from between the two fixed shafts 3, and then the new roller core 1 is installed between the two fixed shafts 3.
