Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire processing technology, specifically a tread grinding machine for processing low rolling resistance light truck tires. Background Technology
[0002] Low rolling resistance light truck tires are high-performance tires designed specifically for light trucks. Their core feature is that by optimizing the structure and materials, the rolling resistance of the tire is reduced, thereby achieving advantages such as energy saving, improved range, or reduced fuel consumption.
[0003] When grinding the tread of low rolling resistance light truck tires, the tire is usually placed on the outer ring of the rotating mechanism. However, because some tires are quite heavy, when the rotating mechanism drives the tire to rotate and grind for a long time, the shaft of the rotating motor is subjected to the weight of the falling tire for a long time, which can easily lead to greater wear and damage to the shaft.
[0004] Therefore, we propose a tread grinding machine for processing low rolling resistance light truck tires to solve the above problems. Utility Model Content

This solves the problem mentioned in the background section: when grinding the tread of low rolling resistance light truck tires, the tire is typically fitted onto the outer ring of a rotating mechanism. However, due to the heavy weight of some tires, the rotating mechanism drives the tire to rotate and grind for extended periods. This causes the rotating motor shaft to experience excessive wear and damage due to the prolonged downward force of the tire.

The output end of the first motor is connected to a threaded rod, and a threaded sleeve is fitted on the outer surface of the threaded rod. A connecting sleeve is fixedly provided on the side wall of the threaded sleeve, and a retaining strip is fixedly provided on the inner side wall of the connecting sleeve. An extension rod extends from the inner cavity of the connecting sleeve, and a retaining groove is opened on the outer ring surface of the extension rod. A rotating wheel is connected to one end of the extension rod, and a retaining roller is connected to the other end of the rotating wheel.
[0011] Furthermore, a second motor is fixedly mounted on one top end of the supporting side plate, and the output end of the second motor is connected to an expansion mechanism, with an arc-shaped inner support seat connected to the outer ring surface of the expansion mechanism.
[0012] Furthermore, a guide seat is fixed on the top of the base away from the supporting side plate, and a drive mechanism is connected to the top of the guide seat. A third motor is fixed at one end of the top of the drive mechanism, and a grinding wheel is connected to the output end of the third motor.
[0013] Furthermore, the inner side of the threaded sleeve has a hole with a diameter that matches the outer diameter of the threaded rod, and the threaded rod and the threaded sleeve form a threaded connection.
[0014] Furthermore, one end of the rotating wheel is rotatably connected to the extension rod via a bearing seat, and the other end of the rotating wheel is rotatably connected to the guide roller via a bearing seat.
[0015] Furthermore, the outer ring surface of the retaining roller has multiple arc-shaped protrusions equidistantly distributed along the center point, and the vertical center lines of the retaining roller extending to support the side plate are symmetrically distributed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a tread grinding machine for processing low rolling resistance light truck tires, including a base 1, a support side plate 2 fixed on one side of the top of the base 1, and a guide groove 3 opened on the front surface of the support side plate 2. The guide groove 3 is opened in an inclined shape and is symmetrically distributed along the vertical center line of the support side plate 2.
[0027] An extension platform 4 is fixedly provided at the bottom of one end of the supporting side plate 2, and a first motor 5 is fixedly provided at the bottom of the extension platform 4. The output end of the first motor 5 is connected to a threaded rod 6, and a threaded sleeve 7 is fitted on the outer surface of the threaded rod 6. An external thread is opened on the outer ring surface of the threaded rod 6, and a threaded connection is formed between the threaded rod 6 and the threaded sleeve 7. A connecting sleeve 8 is fixedly provided on the side wall of the threaded sleeve 7, and a retaining strip 9 is fixedly provided on the inner side wall of the connecting sleeve 8. The retaining strip 9 is evenly distributed along the inner side wall of the connecting sleeve 8, and the outer diameter of the retaining strip 9 is adapted to the inner diameter of the retaining groove 11. An extension rod 10 extends from the inner cavity of the connecting sleeve 8, and a retaining groove 11 is opened on the outer ring surface of the extension rod 10. A rotating wheel 12 is connected to one end of the extension rod 10, and a retaining roller 13 is connected to the other end of the rotating wheel 12.
[0028] In use, when the low rolling resistance light truck tire is initially fitted onto the outer ring surface of the expansion mechanism 15, the first motor 5 operates, causing the threaded rod 6 connected to its output end to rotate. The rotation of the threaded rod 6 drives the threaded sleeve 7, which is threaded onto its outer ring surface, to move longitudinally. This longitudinal movement of the threaded sleeve 7 causes the connecting sleeves 8 fixed on both sides to move as well, facilitating the movement of the connecting sleeves 8 to drive the rotating wheel 12. When the rotating wheel 12 moves, it slides along the guide groove 3, allowing the rotating wheel 12 to drive the extension rod 10 to move inside the connecting sleeve 8, thereby adjusting the distance between the two rotating wheels 12. Simultaneously, the rotation... As the wheel 12 slides along the guide groove 3, it drives the stop roller 13 connected to its other end to adjust its position, thereby causing the stop rollers 13 on both sides to move towards one side of the tire. When the stop roller 13 contacts the tire tread, the drive of the first motor 5 is stopped, thereby achieving the positioning of the stop roller 13. The stop roller 13 is used to provide auxiliary support for the tire. It is worth noting that when the wheel 12 moves along the guide groove 3, it drives the extension rod 10 to move accordingly. At this time, the extension rod 10 slides inside the connecting sleeve 8, thereby causing the slot 11 to slide along the locking strip 9, which can improve the stability of the extension rod 10 during movement.
[0029] like Figure 1 and Figure 3 As shown, in some embodiments, a second motor 14 is fixed at one end of the top of the support side plate 2, and the output end of the second motor 14 is connected to an expansion mechanism 15. An arc-shaped inner support seat 16 is connected to the outer ring surface of the expansion mechanism 15. The arc-shaped inner support seats 16 are equidistantly distributed along the center point of the expansion mechanism 15, and the outer surface of the multiple arc-shaped inner support seats 16 is an arc-shaped surface, which facilitates better contact with the inner wall of the low rolling resistance light truck tire in the future.
[0030] In use, the low rolling resistance light truck tire to be processed is first placed on the outer ring surface of the expansion mechanism 15. Then, the expansion mechanism 15 works to push the arc-shaped inner support seat 16, thereby causing multiple arc-shaped inner support seats 16 to expand outward and contact the inner sidewall of the low rolling resistance light truck tire, thus achieving the support and limiting treatment of the low rolling resistance light truck tire. When the second motor 14 works, it will cause the expansion mechanism 15 connected to its output end to rotate, which facilitates the subsequent rotation of the low rolling resistance light truck tire, and thus allows for better grinding treatment of its surface.
[0031] like Figure 1 As shown, in some embodiments, a guide seat 17 is fixed on the top of the base 1 away from the support side plate 2, and a drive mechanism 18 is connected to the top of the guide seat 17. A third motor 19 is fixed at one end of the top of the drive mechanism 18, and a grinding wheel 20 is connected to the output end of the third motor 19.
[0032] In use, the drive mechanism 18 moves laterally along the guide seat 17, which facilitates the subsequent adjustment of the lateral position of the grinding wheel 20 driven by the drive mechanism 18, so that the grinding wheel 20 can better contact the tire surface. Then, the operation of the third motor 19 can realize the rotation of the grinding wheel 20, and the rotation of the grinding wheel 20 can be used to grind the tread of the low rolling resistance light truck tire.
[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the inner side of the threaded sleeve 7 has a hole with a diameter that matches the outer diameter of the threaded rod 6, and the threaded rod 6 and the threaded sleeve 7 form a threaded connection.
[0034] In use, since the threaded rod 6 and the threaded sleeve 7 are connected by a threaded groove, the longitudinal movement of the threaded sleeve 7 can be easily achieved by rotating the threaded rod 6.
[0035] like Figure 4 As shown, in some embodiments, one end of the rotating wheel 12 is rotatably connected to the extension rod 10 through a bearing seat, and the other end of the rotating wheel 12 is rotatably connected to the guide roller 13 through a bearing seat.
[0036] In use, since the rotating wheel 12 is rotatably connected to the extension rod 10 and the stop roller 13, the rotatable connection between the three can be used to make it easy for the rotating wheel 12 to slide along the guide groove 3 without affecting the extension rod 10 and the stop roller 13.
[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the outer ring surface of the retaining roller 13 has multiple arc-shaped protrusions distributed at equal intervals along the center point, and the retaining roller 13 extends symmetrically along the vertical center line of the supporting side plate 2.
[0038] When in use, since the guide rollers 13 are symmetrically distributed on both sides of the support side plate 2, when the guide rollers 13 come into contact with the bottom sides of the tire to be processed, it is convenient to provide auxiliary support for the tire. The arc-shaped protrusions are used to increase friction and facilitate better tire movement.
[0039] In summary, firstly, the low rolling resistance light truck tire to be processed is fitted onto the outer ring surface of the expansion mechanism 15. Then, the expansion mechanism 15 operates to push the arc-shaped inner support 16, causing multiple arc-shaped inner support 16s to contact and limit the inner wall of the low rolling resistance light truck tire. Subsequently, the first motor 5 operates, causing the threaded rod 6 to rotate and drive the threaded sleeve 7 to move longitudinally. At this time, the threaded sleeve 7 drives its connecting sleeve 8 to move, facilitating the movement of the connecting sleeve 8 to drive the rotating wheel 12. When the rotating wheel 12 moves, it slides along the guide groove 3, thereby causing the rotating wheel 12 to drive the extension rod 10 inside the connecting sleeve 8. The activity is carried out to adjust the distance between the two rotating wheels 12. At the same time, as the rotating wheels 12 slide along the guide groove 3, they will drive the guide rollers 13 to adjust their position, thereby causing the guide rollers 13 on both sides to move towards one side of the tire. When the guide rollers 13 contact the tire tread, the drive of the first motor 5 is stopped. The guide rollers 13 are used to provide auxiliary support for the tire. After the tire is positioned, the drive mechanism 18 works to make the grinding wheel 20 contact the tire tread. Then the third motor 19 works to make the grinding wheel 20 rotate, and the rotation of the grinding wheel 20 is used to grind the tire tread.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
