Description

Technical Field

[0001] This invention belongs to the field of tire processing technology, specifically relating to a deburring device for the surface of rubber tires. Background Technology

[0002] Rubber tires are typically mounted on metal rims to support the vehicle body, cushion external impacts, make contact with the road surface, and ensure vehicle performance. Rubber tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing capacity, traction capacity, and cushioning capacity. After the tires are manufactured, they need to be deburred to ensure that the tires meet quality standards.

[0003] However, currently, deburring rubber tires is generally done manually with a curved blade. During the deburring process, the operator must constantly adjust their standing position. After removing the burrs on one side, the tire must be flipped over. This is labor-intensive and inefficient. In addition, manual scraping is unstable and often leads to damage to the tire surface, which affects the tire quality and results in wasted costs.

[0004] In summary, this solution addresses the technical problem of improving the deburring efficiency of rubber tires without compromising the quality of the tires after deburring. Summary of the Invention

[0014] The bottom end of the adjusting cylinder is hinged to the bottom end of the triangular plate;

[0015] The limiting piece is provided with a long through hole, and the other end of the limiting post is slidably embedded in the long through hole.

[0016] The bottom cutting assembly also includes a rotating shaft that passes vertically through the adjusting rod, a gear and a cutting blade that are coaxially mounted on the rotating shaft, the gear meshing with the gear, and the cutting blade is located at the top of the rotating shaft.

[0018] The position adjustment structure includes a support base, a cylinder one vertically mounted on the support base, a caster wheel located below the support base, and a cylinder two connected at one end to the side of the support base.

[0024] (1) This solution includes a burr cutting structure, which has the following technical advantages:

[0025] Firstly, when the rubber tire is laid flat, the side cutting component can be used to cut the burrs on the side of the rubber tire.

[0026] Secondly, when the rubber tire is laid flat, the bottom cutting component can be used to cut the burrs on the top and bottom surfaces of the rubber tire.

[0027] Third, when the bottom cutting component is working, the adjusting cylinder is used to make the adjusting rod drive the cutting blade one and the cutting blade four to rotate, thereby adjusting the deflection angle of the cutting blades, which can cut burrs on non-horizontal surfaces in rubber tires.

[0029] (2) The lifting structure set in this scheme has the following technical effects:

[0030] First, by using a telescopic cylinder and a pushing arc plate, one end of the pushing arc plate and the telescopic cylinder are inserted into the interior of the rubber tire. Under the action of the lifting cylinder, the lifting plate is raised, the lifting plate drives the telescopic cylinder to rise, the telescopic cylinder drives the rubber tire to rise, and with the assistance of the horizontal moving structure, the transfer of the rubber tire is realized.

[0031] Secondly, after the rubber tire is placed on the support structure, several pushing arc plates are used to push the upper or lower inner side of the rubber tire at the same time, so that the rubber tire is centered, that is, the center of the rubber tire is located on the rotation center of the lower fixed column, which facilitates the subsequent burr cutting process.

[0032] Third, an air blowing pipe and an air blowing hole are provided at the outer end of the telescopic cylinder. The air blowing pipe is connected to the blower.

[0033] (3) This solution includes a position adjustment structure, which has the following technical advantages:

[0034] Firstly, with the support of the casters, the external force drives the support base to rotate around the center of the lower fixed column, thus removing the burrs around the rubber tire.

[0046] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0047] See Figures 1-8 A deburring device for rubber tire surface includes a base 10 and a lower fixing column 12 vertically arranged in the center of the base 10. A plurality of position adjustment structures 9 are arranged in a ring array on the outer side of the lower fixing column 12. The position adjustment structures 9 are connected to the deburring structure 8. A support structure for supporting the rubber tire 6 is arranged above the position adjustment structure 9. The support structure is connected to the lower fixing column 12.

[0048] The top of the lower fixed column 12 is connected to the lifting structure, the lifting structure is connected to the horizontal moving structure, the horizontal moving structure is set on two parallel tracks 1, and the lifting structure is detachably connected to the rubber tire 6.

[0049] More preferably, the horizontal moving structure includes a moving plate 3 and a power wheel 2 set at the bottom of the moving plate. The power wheel 2 is set on the track 1 and moves back and forth on the track to realize the transfer of the rubber tire 6. The two ends of the track 1 are respectively vertically set with columns 7, which are supported on the ground by the columns 7.

[0050] The burr cutting structure 8 includes a side cutting assembly for deburring the outer side of the rubber tire 6 and a bottom cutting assembly for deburring the upper and lower surfaces of the rubber tire 6. The side cutting assembly and the bottom cutting assembly are connected, and the side cutting assembly is mounted on the position adjustment structure 9.

[0051] The side cutting assembly includes a triangular plate 84, with a driving wheel 82, a driven wheel 85 and a driven wheel 840 respectively rotatably mounted at the three corners of the triangular plate 84. A cutting blade 890 is coaxially mounted on the outer side of the driving wheel 82. The cutting blade 890 is parallel to the driving wheel 82. The driving wheel 82 is coaxially connected to the motor shaft of the motor 81.

[0052] A drive belt 83 is simultaneously threaded through the outer sides of the drive wheel 82, driven wheel 85, and driven wheel 840.

[0053] Specifically, the conveyor belt 83 is fitted on the outside of the drive wheel 82, driven wheel 1 85 and driven wheel 3 840. When the drive wheel 82 moves, it will naturally drive the driven wheel 1 85 and driven wheel 3 840 to rotate.

[0054] The bottom cutting assembly includes a driven wheel 810 disposed between driven wheel 1 85 and driven wheel 3 840, a rotating shaft 820 coaxially connected to driven wheel 2 810, a gear 860 coaxially disposed on rotating shaft 2 820, and a cutting blade 870 coaxially disposed at the top of rotating shaft 2 820. Rotating shaft 2 820 passes vertically through adjusting rod 89, adjusting rod 89 is connected to a rotation drive structure, and rotation drive structure is connected to triangular plate 84.

[0055] The bottom end of the rotating shaft 2 820 is provided with a cutting blade 4 821, which is used to cut burrs on the upper surface of the rubber tire 6.

[0056] The driven wheel 810 has an annular groove, and the transmission belt 83 is wound around the annular groove for one revolution. When the transmission belt 83 moves, the driven wheel 810 will naturally rotate under the action of friction.

[0057] The rotation drive structure includes an adjusting cylinder 880 with one end hinged to one end of the adjusting rod 89, a limiting post 850 with one end vertically disposed on both sides of the adjusting rod 89, and a limiting piece 830 connected to the limiting post 850.

[0058] The bottom end of the adjusting cylinder 880 is hinged to the bottom end of the triangular plate 84;

[0059] The limiting piece 830 is provided with a long through hole, and the other end of the limiting post 850 is slidably embedded in the long through hole.

[0060] Under the action of the adjusting cylinder 880, the adjusting rod 89 rotates. At this time, the limiting post 850 slides in the long through hole. The long through hole is arc-shaped, and its arc center is located on the central axis of the transmission belt between the driven wheel 1 85 and the driven wheel 3 840 (therefore, the cross-section of the transmission belt is preferably circular). On the actual rubber tire 6, the inclination of the burrs on the upper and lower bottom surfaces is not large. Therefore, the adjusting cylinder 880 only achieves fine adjustment in the end.

[0061] The bottom cutting assembly also includes a rotating shaft 87 that passes vertically through the adjusting rod 89, a gear 88 and a cutting blade 86 coaxially mounted on the rotating shaft 87, the gear 88 meshing with the gear 860, and the cutting blade 86 being mounted at the top of the rotating shaft 87.

[0062] The position adjustment structure 9 includes a support base 92, a cylinder 91 vertically mounted on the support base 92, a caster wheel 93 mounted below the support base 92, and a cylinder 94 with one end connected to the side of the support base 92. The bottom end of the cylinder 94 is connected to the lower fixed column 12.

[0063] The lifting structure includes a lifting plate 51 whose bottom surface is detachably connected to the top of the lower fixed column 12, several telescopic cylinders 53 arranged in a ring array on the outside of the lifting plate 51, an upper fixed column 5 whose bottom end is coaxially arranged above the center of the lifting plate 51, and a lifting cylinder 4 connected to the top of the upper fixed column 5. The bottom end of the telescopic cylinder 53 is vertically connected to the outside of the lifting plate 51, and the telescopic end of the telescopic cylinder 53 is provided with a pushing arc plate 54. The top of the lifting cylinder 4 is connected to the horizontal moving structure.

[0064] The top of the upper fixed column 5 is provided with an internal thread, and the telescopic end of the lifting cylinder 4 is connected to the internal thread.

[0065] The telescopic cylinder 53 has an air blowing hole 521 at its telescopic end, and an air blowing pipe 52 is provided on the outside of the telescopic end. One end of the air blowing pipe 52 is connected to the air blowing hole 521, and the other end is connected to the fan 16, which is connected to the horizontal moving structure.

[0066] The support structure includes a rotating ring 13 sleeved on the lower fixed column 12, several supporting horizontal columns 14 arranged in a ring array on the outside of the rotating ring 13 at one end, and a supporting arc plate 15 arranged at the other end of the supporting horizontal columns 14.

[0067] The specific working process of this invention:

[0068] In this scheme, a conveyor structure (such as a conveyor belt) is provided on both sides of the base 10. Using the horizontal moving structure, the lifting plate 51 is moved to the conveyor structure on one side. The conveyor structure has a rubber tire 6. At this time, the inner side of the rubber tire 6 is open, and several pushing arc plates 54 (three are provided in this scheme) are inserted into the rubber tire 6. Under the action of the lifting cylinder 4, the upper fixed column 5 is lifted, and the upper fixed column 5 drives the lifting plate 51 to rise.

[0069] It should be noted that, in order to simplify the design, the two transmission structures are not shown in the attached drawings, but this is not an innovative point of this solution, and those skilled in the art can easily implement it, so it will not be described in detail here.

[0070] At this time, the horizontal moving structure moves to the upper end of the lower fixed column 12. Since the lifting plate 51 and the lower fixed column 12 can be detachably connected, an embedded column can be set at the bottom of the lifting plate 51 and an embedded groove can be set at the top of the lower fixed column 12. The embedded column can be inserted into the embedded groove to limit the overall lifting structure. The subsequent separation is also convenient and quick.

[0071] After the rubber tire 6 is laid flat, that is, after the rubber tire 6 is placed on the support structure, several pushing arc plates 54 are used to push the inner side of the rubber tire 6 at the same time, so that the rubber tire 6 is centered, that is, the center of the rubber tire 6 is located on the rotation center of the lower fixed column 12, which facilitates the subsequent burr cutting process.

[0072] An air blowing pipe 52 and an air blowing hole 521 are provided at the outer end of the telescopic cylinder 53. The air blowing pipe 52 is connected to the blower 16. Under the action of the blower 16, the burrs that fall into the rubber tire 6 are blown out.

[0073] A cutting blade 3 890 is provided on the drive wheel 82. The cutting blade 3 890 is set vertically and is attached (tangentially) to the outside of the rubber tire 6. Specifically, the outer edge of the cutting blade 3 890 is perpendicular to the burr, and the burr is generally set perpendicular to the outside of the rubber tire 6. Therefore, under the action of the side cutting component, the burr can be cut off efficiently and quickly.

[0074] After the burrs on the outer side of the rubber tire 6 are cut off, the bottom cutting assembly can be used to cut the burrs on the upper and lower bottom surfaces of the rubber tire 6. That is, by adjusting the extension and retraction of cylinder 1 91 and cylinder 2 94, the cutting blade 1 86 is positioned horizontally on the lower bottom surface of the rubber tire 6, and the cutting blade 4 821 is positioned on the upper bottom surface of the rubber tire 6 to remove the burrs on the upper and lower bottom surfaces of the rubber tire 6. By adjusting the action of cylinder 880, the deflection angle of cutting blade 1 86 is adjusted, so that the adjusting rod 89 drives cutting blade 1 86 to rotate, thereby adjusting the deflection angle of cutting blade 1 86 and cutting blade 4 821. This can cut burrs on non-horizontal surfaces in the rubber tire 6.

[0075] This solution also includes a second cutting disc 870. The second gear 860 actually drives the first gear 88 to rotate. The rotation of the second gear 860 drives the second cutting disc 870 to rotate. When the size of the rubber tire 6 is small, the second cutting disc 870 is generally used to remove burrs. In this case, the first gear 88 and the first cutting disc 86 are no longer used.

[0076] For larger rubber tires 6, when removing burrs near the inner side of the upper and lower bottom surfaces, the rubber tire 6 may interfere with the cutting disc 3 890. In this case, gear 1 88 and cutting disc 1 86 are used, and cutting disc 1 86 and cutting disc 4 821 are used to remove burrs from the upper and lower bottom surfaces of the rubber tire 6.

[0077] The coordinated use of the side-cutting and bottom-cutting components helps simplify the overall structure and reduce costs;

[0078] After the entire cutting process is completed, the telescopic cylinder 53 and the push arc plate 54 are used to insert one end of the push arc plate 54 and the telescopic cylinder 53 into the interior of the rubber tire 6. Under the action of the lifting cylinder 4, the lifting plate 51 is lifted, the lifting plate 51 drives the telescopic cylinder 53 to rise, the telescopic cylinder 53 drives the rubber tire 6 to rise, and with the assistance of the horizontal moving structure, the rubber tire 6 is transferred. After the transfer, the rubber tire 6 is placed on the conveying structure on the other side of the base 10 and transported out.

[0079] This solution includes a position adjustment structure 9. With the support of the caster wheel 93, the external force drives the support base 92 to rotate around the center of the lower fixed column 12, thereby removing burrs around the rubber tire 6. Under the adjustment of cylinder 1 91 and cylinder 2 94, the cutting positions of the bottom cutting component and the side cutting component are adjusted, thereby achieving more comprehensive burr cutting of the rubber tire 6.

[0080] It should be noted that in this solution, the burr cutting structure 8 can also be fixed and the rubber tire 6 can be rotated to cut the burrs. After the burrs are cut, they fall into the collection trough plate 11 for collection.

[0081] The deburring device for rubber tires provided in this solution achieves a comprehensive technical effect of transferring, supporting, centering and deburring rubber tires. It has multi-functional technical features and greatly improves production efficiency.

[0082] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
