Description

Technical Field

[0001] The invention belongs to the technical field of self-aligning rollers, in particular to a double-sided rotating self-aligning roller. Background Art

[0002] Rollers are important components of belt conveyors. They are of many types and large in number. They can support the weight of conveyor belts and materials. As the name suggests, double-sided rollers are rollers on which belts can slide on both sides. With the development of technology, self-aligning rollers have appeared on the market. When the belt deviates and triggers the self-aligning rollers to rotate around the center axis, the inclined rollers on both sides will interfere with the belt groove section. The belt will generate resistance to the rotation of the self-aligning rollers, preventing them from rotating around the center axis. For example, a double-sided rotating self-aligning roller invented with application number CN202211230813.0 includes a base and a belt, wherein a plurality of support plates are installed on the upper side of the base, and a main roller and two side rollers corresponding to the belt are respectively rotatably matched on the upper side of the plurality of support plates. The two side rollers are located at both ends of the main roller, and one end of the two side rollers is rotatably matched with a plurality of rollers. Two pull rods are rotatably matched between the base and the support plates, and two rotating rods corresponding to the pull rods are slidably matched. In the present invention, the main roller and the two side rollers are respectively installed on the upper side of the support plates, and then rollers are installed at one end of the side rollers. The rollers can limit the belt to reduce the possibility of the belt directly running off the track and flying out. By installing the pull rod and the rotating rod between the base and the support plate, when the belt runs off the track, the pull rod can be driven to pull the rotating rod by squeezing the opposite side roller of the belt, thereby pulling the main roller and the other side roller to tilt. This device can adjust the belt tilt during operation, but cannot limit the position of the adjusted belt, so the position of the belt needs to be adjusted frequently. The existing double-sided rotating self-aligning rollers are generally fixedly installed. When different angles need to be adjusted, the double-sided rotating self-aligning rollers need to be replaced. When replacing the double-sided rotating self-aligning rollers, the operator needs to disassemble and install them, and disassembling and installing the double-sided rotating self-aligning rollers requires a lot of time, which reduces work efficiency. Therefore, it needs to be improved. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides a double-sided rotating self-aligning roller, comprising a fixed base 1 and a conveyor belt body 6, a fixed bracket 2 and a mounting bracket 3 are fixedly mounted on the top of the fixed base 1, a first roller 4 is provided on the upper end of the mounting bracket 3, a connector 10 is hingedly connected to one side of the mounting bracket 3, an adjustment assembly 8 is fixedly mounted on the top of the fixed bracket 2, a driving assembly 7 is movably connected to the inner cavity of the fixed base 1, a second roller 5 is fixedly connected to the connector 10, an adjustment assembly 8 is provided on the upper end of the driving assembly 7, and a limit assembly 9 is fixedly mounted on the upper end of the adjustment assembly 8; The drive assembly 7 includes a mounting post 701, a mounting ring 702 and a second bevel gear 707 are fixedly mounted on the outer side of the mounting post 701, a connecting plate 703 is fixedly connected to the outer side of the mounting ring 702, a connecting rod 704 is provided on the end of the connecting plate 703 away from the mounting ring 702, a connecting block 705 is provided on the end of the connecting rod 704 away from the connecting plate 703, and a first bevel gear 706 is meshedly connected to the outer side of the second bevel gear 707; The adjustment assembly 8 includes a first spring telescopic rod 801, a first mounting member 802 is fixedly mounted on the top of the first spring telescopic rod 801, a mounting support member 803 is fixedly mounted on the top of the first mounting member 802, and a fixed adjustment member 804 is fixedly mounted on the bottom of the mounting support member 803; The limiting assembly 9 includes a support column 901 , a mounting plate 902 is fixedly mounted on the top of the support column 901 , and a limiting column 903 is fixedly mounted on the bottom of the mounting plate 902 .

[0020] The above scheme is adopted: through the cooperation of the driving assembly 7 and the adjusting assembly 8, the connecting shaft 709 drives the mounting column 701, the mounting ring 702, the connecting plate 703 and the second bevel gear 707 to rotate, the connecting plate 703 drives the connecting rod 704 and the connecting block 705 to move, and the connecting block 705 drives the rectangular plate 708 to move, and the rectangular plate 708 slides in the arc groove of the fixed adjusting member 804. When sliding inward in the arc groove of the fixed adjusting member 804, the angle between the first roller 4 and the second roller 5 becomes larger. At this time, the second spring telescopic rod 805 contracts and the first spring telescopic rod 801 expands. When sliding outward in the arc groove of the fixed adjusting member 804, the angle between the first roller 4 and the second roller 5 becomes smaller, the first spring telescopic rod 801 contracts, and the second spring telescopic rod 805 expands, thereby better adjusting the angle of the bilateral rotary self-aligning roller, avoiding the large amount of time consumed by replacing the bilateral rotary self-aligning rollers when the angle needs to be adjusted.

[0021] like Figure 2 、 Figure 5 and Figure 6 As shown, a connecting shaft 709 is fixedly installed in the middle of the first bevel gear 706, a rectangular plate 708 is fixedly installed on the top of the connecting block 705, a second spring telescopic rod 805 is elastically supported between the fixed bracket 2 and the fixed adjustment member 804, and the second roller 5 and the connecting member 10 are fixedly connected.

[0022] The above solution is adopted: through the design of the rectangular plate 708 and the connecting shaft 709, the design of the connecting shaft 709 makes it possible that when the connecting shaft 709 is rotated, the connecting shaft 709 drives the first bevel gear 706, the mounting column 701 and the mounting ring 702 to rotate, thereby driving the connecting rod 704 and the connecting block 705 to rotate, so that the connecting block 705 drives the rectangular plate 708 to move, and the rectangular plate 708 slides in the arc-shaped slide groove of the fixed adjustment member 804, thereby adjusting the angle of the double-sided rotary self-aligning roller, so that the angle can be quickly adjusted according to different needs. Through the cooperation of the second roller 5 and the connecting member 10, the design of the second spring telescopic rod 805 makes it possible that when the rectangular plate 708 slides to adjust the angle, the second spring telescopic rod 805 is telescoped to adapt to the angle to be adjusted. The second roller 5 and the connecting member 10 are fixedly connected, and the connecting member 10 is movably connected to the mounting bracket 3, so that when the angle of the second roller 5 is adjusted, the connecting member 10 limits one end of the second roller 5, so that the second roller 5 can be adjusted faster.

[0023] like Figure 4 、 Figure 7As shown, an arc-shaped groove is provided at the bottom of the fixed adjustment member 804, the fixed adjustment member 804 is movably connected to the rectangular plate 708, the end of the connecting shaft 709 away from the first bevel gear 706 is movably connected to the fixed base 1, and the mounting column 701 is movably connected to the fixed base 1.

[0024] The above scheme is adopted: by cooperating with the fixed adjusting member 804 and the rectangular plate 708, and opening the arc-shaped slide groove at the bottom of the fixed adjusting member 804, the rectangular plate 708 is limited when the rectangular plate 708 moves at the bottom of the fixed adjusting member 804, so that the stability during movement is better, and thus the angle is better adjusted. By cooperating with the connecting shaft 709 and the fixed base 1, the connecting shaft 709 is movably connected to the fixed base 1, so that the fixed base 1 limits the connecting shaft 709, so that the connecting shaft 709 is rotated, and the connecting shaft 709 drives the first bevel gear 706, the mounting post 701 and the mounting ring 702 to rotate, thereby adjusting the angle of the roller, and the mounting post 701 is movably connected to the fixed base 1, and the fixed base 1 limits the mounting post 701, so that when the connecting shaft 709 drives the mounting post 701 to rotate, the mounting post 701 can operate stably.

[0025] like Figure 4 and Figure 6 As shown, a roller is provided at the bottom of the limiting column 903 and is movably connected to the conveyor belt body 6 , a small roller is provided at the top of the rectangular plate 708 , and the rectangular plate 708 is fixedly connected to the support column 901 .

[0026] The above scheme is adopted: through the design of the limiting column 903 and the design of the roller at the bottom of the limiting column 903, the conveyor belt body 6 is resisted during operation, making the conveyor belt body 6 more stable and not prone to deflection. If the conveyor belt body 6 deflects, the support column 901 can block the conveyor belt body 6, thereby achieving a better effect in avoiding tilting. Through the design of the small roller on the top of the rectangular plate 708, the rectangular plate 708 is more convenient to move in the arc groove of the fixed adjustment member 804, thereby making it more convenient to adjust the angle. The support column 901 is fixedly connected to the rectangular plate 708, so that the connecting block 705 drives the rectangular plate 708 to move, and the rectangular plate 708 drives the support column 901, the mounting plate 902 and the limiting column 903 to move, so that the support column 901 and the rectangular plate 708 move synchronously, thereby better limiting the conveyor belt body 6 and adjusting the angle.

[0027] like Figure 2 、 Figure 7 and Figure 8As shown, the shape of the fixed adjustment member 804 is trapezoidal, the second roller 5 is fixedly connected to the second spring telescopic rod 805, a groove is provided on the surface of the fixed base 1, the middle part of the fixed bracket 2 is "T"-shaped, the rectangular plate 708 is movably connected to the groove, and a handwheel is provided on the top of the connecting shaft 709.

[0028] The above scheme is adopted: through the design of the fixed adjustment member 804 and the trapezoidal design of the fixed adjustment member 804, the angle can be adjusted better, the second roller 5 is fixedly connected to the second spring telescopic rod 805, and after the rectangular plate 708 is adjusted to the angle in the arc-shaped slide groove at the bottom of the fixed adjustment member 804, the angle of the second roller 5 is also determined, and the fixed adjustment member 804 is fixedly installed with the mounting support member 803. Through the design of the fixed base 1 and the opening of the groove, the rectangular plate 708 moves in the groove on the surface of the fixed base 1, so that the rectangular plate 708 can better adjust the angles of the rollers on both sides, and the middle part of the fixed bracket 2 is The "T" shape can better fix the second spring telescopic rod 805, so that the second spring telescopic rod 805 supports the second roller 5, and then better adjust the angle of the roller, so that it can adapt to more situations. Through the design of the connecting shaft 709 and the design of the handwheel on the top of the connecting shaft 709, it is more convenient to rotate the connecting shaft 709, so that the connecting shaft 709 drives the mounting column 701, the mounting ring 702, the connecting plate 703 and the second bevel gear 707 to rotate, the connecting plate 703 drives the connecting rod 704 and the connecting block 705 to move, and the connecting block 705 drives the rectangular plate 708 to move for more urgent and convenient operation.

[0029] The working principle and use process of the present invention: When in use, if the angle of the roller needs to be adjusted, turn the handwheel on either side, the handwheel drives the connecting shaft 709 to rotate, the connecting shaft 709 drives the mounting column 701, the mounting ring 702, the connecting plate 703 and the second bevel gear 707 to rotate, the connecting plate 703 drives the connecting rod 704 and the connecting block 705 to move, the connecting block 705 drives the rectangular plate 708 to move, and the rectangular plate 708 slides in the arc-shaped slide groove of the fixed adjustment member 804; When the arc chute of the fixed adjustment member 804 slides inward, the angle between the first roller 4 and the second roller 5 becomes larger. At this time, the second spring telescopic rod 805 contracts and the first spring telescopic rod 801 expands. When the arc chute of the fixed adjustment member 804 slides outward, the angle between the first roller 4 and the second roller 5 becomes smaller, the first spring telescopic rod 801 contracts, and the second spring telescopic rod 805 expands, thereby better adjusting the angle of the double-sided rotating self-aligning rollers, avoiding the large amount of time consumed in replacing the double-sided rotating self-aligning rollers when the angle needs to be adjusted. When the rectangular plate 708 moves, the rectangular plate 708 drives the limit assembly 9 to move, and the support column 901, the mounting plate 902 and the limit column 903 move, thereby limiting the conveyor belt body 6. The dead conveyor belt body 6 is more stable during operation, avoiding the situation where the conveyor belt body 6 tilts due to the long conveying distance, thereby reducing the occurrence of accidents.
