Description

Technical Field

[0001] This utility model relates to the field of idler roller assembly technology, and in particular to an imperial-sized upward-adjusting idler roller assembly. Background Technology

[0002] When feeding materials via belt, several self-aligning idler sets are usually installed at the bottom of the belt. When the belt deviates, it drives the self-aligning idler sets to deflect. The idler sets generate a frictional force that causes the conveyor belt to return to its balanced position, thus realizing the automatic correction of the conveyor belt.

[0003] The existing imperial-based eccentric idler sets lack an auxiliary support structure at the bottom of the idler set base during rotation. All forces are applied to a single fulcrum, which can easily lead to equipment loosening and decreased stability after long-term use.

[0004] Therefore, to address the problem that existing imperial-sized upward-adjusting idler sets lack bottom auxiliary support structures during use, resulting in all forces acting on a single fulcrum and potentially leading to equipment loosening and decreased stability over long-term use, an imperial-sized upward-adjusting idler set can be designed. By setting up support columns, mounting rods can be installed, thereby mounting connecting rods, limit blocks, and rollers. When the idler set is put into use, the friction of the belt on the two lateral idlers will cause the mounting base to drive the rotating rod to rotate, thereby causing the pallet to rotate synchronously. At this time, the rollers will rotate due to the friction of the sliding groove, thus providing auxiliary support for the various components on the upper side of the rotating rod and improving the stability of the device. Utility Model Content

[0005] To overcome the problem that existing imperial-based eccentric idler sets lack a bottom auxiliary support structure during use, all forces are applied to a single fulcrum, which can easily lead to equipment loosening and decreased stability after long-term use.

[0006] The technical solution of this utility model is as follows: an imperial-sized upper-adjusting idler roller assembly, including a base; it also includes a tray, a chute, a support column, a mounting rod, a connecting rod, a limiting block, and rollers. A fixed seat is provided at the middle position of the inner surface of the base, a slewing bearing is embedded at the middle position of the upper surface of the fixed seat, a fixed plate is provided on the upper surface of the fixed seat, a positioning ring is provided at the middle position of the upper surface of the fixed plate, a rotating rod is provided on the inner ring surface of the slewing bearing, a limiting ring is provided at the upper position of the outer surface of the rotating rod, a tray is provided on the upper surface of the rotating rod, a chute is opened at the outer edge of the bottom surface of the tray, and the upper surface of the fixed plate... Support columns are provided on both the front and rear sides of the positioning ring. Two symmetrical mounting rods are provided on the top surface of the support columns. A connecting rod is rotatably connected between the two mounting rods. Limit blocks are provided at both ends of the connecting rod. Rollers are provided on the outer surface of the connecting rod, and the rollers match the slide groove. A mounting seat is provided on the top surface of the rotating rod. Two symmetrical partition seats are provided inside the mounting seat. Rotating rods are connected to the left and right sides of the two partition seats. A transverse roller is provided on the outer surface of the rotating rod located in the middle position, and lateral rollers are provided on the outer surfaces of the two rotating rods located on the sides.

[0007] Preferably, by setting up a support column, the mounting rod can be installed, thereby installing the connecting rod, the limiting block, and the roller. When the idler roller assembly is put into use, the two lateral idler rollers will be affected by the friction of the belt, causing the mounting base to drive the rotating rod to rotate, thereby driving the pallet to rotate synchronously. At this time, the roller will rotate due to the friction of the sliding groove, thus providing auxiliary support for the various components on the upper side of the rotating rod and improving the stability of the device. This solves the problem that existing imperial-based top-adjusting idler roller assemblies lack a bottom auxiliary support structure when the idler roller assembly base rotates, and all forces are applied to a single fulcrum, which can easily lead to loosening of the equipment and decreased stability after long-term use.

[0008] Preferably, the outer surface of the rotating rod is provided with two symmetrical auxiliary bearings, and the outer ring surface of the auxiliary bearings is in contact with the inner surface of the corresponding transverse roller and the lateral roller.

[0009] Preferably, positioning blocks are symmetrically arranged at both ends of the rear surface of the mounting base, and a limit rod is rotatably connected to the upper surface of the positioning blocks.

[0010] Preferably, positioning seats are provided on both the left and right sides of the base, and two symmetrical positioning holes are provided on the upper surface of the positioning seats.

[0011] Preferably, the top of the inner surface of the chute has several circumferentially distributed adjustment holes, and a stop block is inserted into the adjustment hole.

[0012] Preferably, screw holes are provided at the corners of the upper surface of the fixing base, and fixing screws are provided at the corners of the upper surface of the fixing plate. The fixing plate is fixed to the fixing base by the fixing screws.

[0013] Preferably, both lateral rollers have trapezoidal cross-sections.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up support pillars, mounting rods can be installed, thereby installing connecting rods, limit blocks, and rollers. When the idler assembly is put into use, the two lateral idlers, affected by the friction of the belt, will cause the mounting base to drive the rotating rod to rotate, thereby driving the pallet to rotate synchronously. At this time, the rollers will rotate due to the friction of the sliding groove, thus providing auxiliary support for the various components on the upper side of the rotating rod and improving the stability of the device. The auxiliary bearings use three-series tapered bearings, which have a lifespan three to five times that of ordinary idler bearings. The two ends of the rotating rod are sealed with oil-filled screw heads and can be fixedly connected to the mounting base and the partition seat, ensuring a firm connection between the idler and the mounting bracket. This effectively strengthens the structure and safety, thus solving the problem that existing imperial-based top-adjusting idler assemblies lack a bottom auxiliary support structure when the idler base rotates, causing all forces to act on a single fulcrum, which can easily lead to equipment loosening and decreased stability after long-term use.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of an imperial-sized upper-adjusting idler roller assembly, including a base 1; it also includes a tray 8, a chute 9, a support column 10, a mounting rod 11, a connecting rod 12, a limiting block 13, and rollers 14. A fixed seat 2 is provided at the middle position of the inner surface of the base 1, a rotary bearing 3 is embedded at the middle position of the upper surface of the fixed seat 2, a fixed plate 4 is provided on the upper surface of the fixed seat 2, a positioning ring 5 is provided at the middle position of the upper surface of the fixed plate 4, a rotating rod 6 is provided on the inner ring surface of the rotary bearing 3, and the outer surface of the rotating rod 6 is close to... A limit ring 7 is provided at the upper position. A tray 8 is provided on the upper surface of the rotating rod 6. A groove 9 is provided on the outer edge of the bottom surface of the tray 8. Support columns 10 are provided on both the front and rear sides of the positioning ring 5 on the upper surface of the fixing plate 4. Two symmetrical mounting rods 11 are provided on the top surface of the support columns 10. A connecting rod 12 is rotatably connected between the two mounting rods 11. Limit blocks 13 are provided at both ends of the connecting rod 12. Rollers 14 are provided on the outer surface of the connecting rod 12. The rollers 14 match the groove 9. The top surface of the rotating rod 6... The device is equipped with a mounting base 15, inside which are two symmetrical partition seats 16. Rotating rods 17 are connected to the left and right surfaces of the two partition seats 16. A transverse idler roller 18 is provided on the outer surface of the rotating rod 17 located in the middle position, and a lateral idler roller 19 is provided on the outer surface of the two rotating rods 17 located on the sides. By setting a support column 10, the mounting rod 11 can be installed, thereby installing the connecting rod 12, the limiting block 13, and the roller 14. When the idler group is put into use, the two lateral idlers 19 will cause the mounting base 15 to drive the rotating rod 6 to rotate due to the friction of the belt, thereby driving the tray 8 to rotate synchronously. At this time, the roller 14 will rotate due to the friction of the sliding groove 9, thus providing auxiliary support for the various components on the upper side of the rotating rod 6 and improving the stability of the device. This solves the problem that existing imperial-based top-adjusting idler groups lack a bottom auxiliary support structure when the idler group base rotates, and all forces are applied to a single fulcrum, which can easily lead to loosening of the equipment and decreased stability after long-term use.

[0025] Please see Figures 1-5 In this embodiment, two symmetrical auxiliary bearings 20 are provided on the outer surface of the rotating rod 17. The outer ring surface of the auxiliary bearing 20 is in contact with the inner surface of the corresponding transverse roller 18 and lateral roller 19. By setting the auxiliary bearings 20, the sensitivity and flexibility of the rotation of the transverse roller 18 and lateral roller 19 can be improved, thereby improving the adjustment accuracy. Positioning blocks 21 are symmetrically arranged on the left and right ends of the rear surface of the mounting base 15. The upper surface of the positioning block 21 is rotatably connected to the limiting rod 22. After the device is installed as a whole, the limiting rod 22 can limit the side position of the belt to avoid large displacement deviation of the belt. Positioning seats 23 are provided on both the left and right sides of the base 1. The upper surface of the positioning seat 23 is provided with two symmetrical positioning holes 24. By setting the positioning seats 23 and the positioning holes 24, it is convenient for the staff to fix the base 1 to the ground, which facilitates operation and improves installation efficiency.

[0026] Please see Figures 1-6 In this embodiment, the top of the inner surface of the chute 9 is provided with several circumferentially distributed adjustment holes 25. A stop block 26 is inserted into the adjustment hole 25. By setting the adjustment hole 25, the operator can select the insertion position of the stop block 26 according to the specific situation. After the stop block 26 is installed, it can abut against the roller 14, thereby limiting the rotation angle of the tray 8 and avoiding large-scale rotation. Screw holes 27 are opened at the corners of the upper surface of the fixed seat 2, and fixing screws 28 are provided at the corners of the upper surface of the fixed plate 4. The fixed plate 4 is fixed to the fixed seat 2 by fixing screws 28. By setting the screw holes 27 and fixing screws 28, the operator can easily disassemble and assemble the fixed plate 4, thereby facilitating the addition of lubricating oil to the rotary bearing 3 and routine maintenance. The cross-section of the two side rollers 19 is a trapezoidal structure. By designing the cross-section of the two side rollers 19 as trapezoidal, the whole presents a cone-like structure, which makes the side rollers 19 have good wear resistance and can withstand greater conveyor belt pressure and material weight, thereby extending their service life.

[0027] During operation, the auxiliary bearing 20 enhances the sensitivity and flexibility of the rotation of the transverse idler roller 18 and the lateral idler roller 19, thereby improving adjustment accuracy. The limiting rod 22, after the entire device is installed, restricts the side position of the belt, preventing significant displacement deviation. The positioning seat 23 and positioning hole 24 facilitate the fixing of the base 1 to the ground, simplifying operation and improving installation efficiency. The adjustment hole 25 allows the operator to select the insertion position of the stop block 26 according to specific conditions. After installation, the stop block 26 abuts against the roller 14, limiting the rotation angle of the tray 8 and preventing large-scale rotation. By setting screw holes 27 and fixing screws 28, it is easy for staff to disassemble and assemble the fixing plate 4, which facilitates the addition of lubricating oil and routine maintenance of the rotary bearing 3. By designing the cross-section of the two side idlers 19 as trapezoidal, the overall structure presents a similar conical structure, which gives the side idlers 19 good wear resistance and the ability to withstand greater conveyor belt pressure and material weight, thereby extending their service life. The auxiliary bearing 20 adopts a three-series conical bearing, which has a lifespan three to five times that of ordinary idler bearings. The two ends of the rotating rod 17 are sealed with oil-fillable screw heads and can be fixedly connected to the mounting base 15 and the partition base 16, ensuring a firm connection between the idler and the mounting bracket, which can effectively strengthen the structure and safety.

[0028] Through the above steps, by setting the support column 10, the mounting rod 11 can be installed, thereby installing the connecting rod 12, the limiting block 13, and the roller 14. When the idler group is put into use, the two lateral idlers 19 will be affected by the friction of the belt, causing the mounting base 15 to drive the rotating rod 6 to rotate, thereby driving the tray 8 to rotate synchronously. At this time, the roller 14 will rotate due to the friction of the sliding groove 9, thus providing auxiliary support for the various components on the upper side of the rotating rod 6 and providing stability to the device. This solves the problem that when the existing imperial upper-adjustment idler group is in use, the idler group base lacks a bottom auxiliary support structure when rotating, and all forces are applied to a single fulcrum, which can easily lead to loosening of the equipment and decreased stability after long-term use.
