Description

Technical Field

[0001] This invention relates to the field of conveying equipment, and more particularly to a roller assembly with a drill-free intermediate frame. Background Technology

[0002] Currently, during the conventional installation of belt conveyors, many holes need to be drilled in the intermediate frame supporting the idler roller group. Errors during on-site installation can easily cause the center line of the idler roller group to be non-perpendicular to the center line of the belt conveyor, resulting in belt deviation. Adjustments often require recutting holes, which is labor-intensive. At the same time, the fixed position is too restricted, and repeated drilling is required when adjusting the position, which affects the strength of the overall support. The published patent 202322569925.5 discloses a combined pallet roller conveyor. The rollers have guide rails at both ends at the same height, connecting the left and right guide rails into a single structure. A bracket connects to the bottom of the guide rails for support. Universal casters are mounted on the guide rails, enabling the pallets to roll and rub in both horizontal and vertical directions, reducing friction between the pallets and baffles. A switch bracket is located on the outer side of the guide rails, and a reflective detection switch is mounted on the switch bracket. The signal is emitted through an opening in a bent plate, facilitating adjustment of the roller spacing on the guide rails to accommodate different pallet lengths and the installation of other equipment inside the roller conveyor, thus simplifying equipment debugging and maintenance. The roller conveyor is driven by a drive device installed below the guide rails, which rotates the rollers via a chain. However, the above structure still suffers from the problem of requiring drilling holes in the frame for the installation of the idler roller assembly. Therefore, solving the problem of the current requirement to drill holes in the frame for idler roller assembly installation, which causes the centerline of the idler roller assembly to be non-perpendicular to the centerline of the conveyor belt, and the need for re-drilling when adjusting the position, is particularly important. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a roller assembly with a drill-free intermediate frame. The roller assembly is fixed in position on the intermediate frame using clamping buckles, eliminating the need for drilling and preventing damage to the frame. Furthermore, the clamping buckles can be released to adjust the position, thus solving the problem that current roller assembly installation requires drilling holes in the frame, resulting in the roller assembly's centerline not being perpendicular to the conveyor belt's centerline, and requiring re-drilling when adjusting the position.

[0004] This invention provides a roller assembly with a drill-free intermediate frame, comprising an intermediate frame and roller assemblies mounted on the intermediate frame. The roller assemblies include three sets of rollers, with the middle roller arranged parallel to the intermediate frame and the two side rollers arranged at an angle of ° to the intermediate frame. The middle roller and the two side rollers are connected and fixed by connecting bends. A bracket is provided at the end of the two side rollers away from the middle roller, and the bottom end of the bracket is clamped to the side of the intermediate frame by a clamping buckle.

[0005] A further improvement is that the clamping buckle is equipped with a locking bolt, which is tightened to lock the clamping buckle. The clamping buckle adopts a structure that can fit two planes together and be tightened by the upper and lower side plates.

[0006] A further improvement is that the clamping buckle is equipped with a tensioning triangular piece, which fixes the locking bolt and improves the fastening stability.

[0007] A further improvement is that a speed limiting rod is provided between the bracket and the two side rollers. The speed limiting rod is mounted on the bracket via a rotating shaft at the rear end. The speed limiting rod rotates around the rotating shaft as its axis, thereby pressing against the two side rollers and limiting the speed when necessary.

[0008] A further improvement is that a limiting baffle is provided at the lower end of the clamping buckle to limit the lateral position of the clamping buckle.

[0009] A further improvement is that a buffer spring is provided at the lower end of the connecting bend, which buffers the connecting bend and reduces the impact received by the idler roller assembly.

[0010] The beneficial effects of this invention are as follows: the clamping buckle fixes the position of the idler roller assembly on the intermediate frame, eliminating the need for drilling and preventing damage to the frame. The clamping buckle can be loosened when position adjustment is needed, facilitating the adjustment of the idler roller assembly's position. The tensioning triangular plate secures the locking bolts, improving fastening stability. The speed limiter lever limits the speed of the idler roller assembly when necessary, enhancing adaptability. Furthermore, the limit baffle and buffer spring improve the overall stability and safety of the equipment. Attached Figure Description

[0014] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0015] like Figure 1-2As shown, this embodiment provides a drill-free idler roller assembly with an intermediate frame, including an intermediate frame 1 and an idler roller assembly 2 mounted on the intermediate frame 1. The idler roller assembly 2 includes three sets of idlers. The middle idler roller is parallel to the intermediate frame 1, and the two side idlers rollers are positioned at a 45° angle to the intermediate frame 1. The middle idler roller and the two side idlers rollers are connected and fixed by a connecting bend 3. A bracket 4 is provided at the end of the two side idlers rollers away from the middle idler roller. The bottom end of the bracket 4 is clamped to the side of the intermediate frame 1 by a clamping buckle 5. A locking bolt 6 is provided on the clamping buckle 5, and the clamping buckle 5 is locked by tightening the locking bolt 6. A tensioning triangle 7 is provided on the clamping buckle 5, and the tensioning triangle 7 is used to fix the locking bolt 6, improving the fastening stability. A speed limiting rod 8 is provided between the bracket 4 and the two side idlers rollers. The speed limiting rod 8 is mounted on the bracket 4 via a rotating shaft 9 at the rear end. The speed limiting rod 8 rotates around the rotating shaft 9, thereby pressing against the two side idlers rollers and limiting the speed when necessary. A limit baffle 10 is provided at the lower end of the clamping buckle 5 to limit the lateral position of the clamping buckle 5. A buffer spring 11 is provided at the lower end of the connecting bend 3 to buffer the impact on the connecting bend 3 and reduce the impact received by the idler roller assembly 2. The clamping buckle 5 fixes the position of the idler roller assembly 2 on the intermediate frame 1, which can fix the position of the support 4 without drilling, avoiding damage to the frame. At the same time, the clamping buckle 5 can be loosened when the position needs to be adjusted, which is convenient for adjusting the position of the idler roller assembly 2. The tensioning triangle 7 fixes the locking bolt 6 to improve the fastening stability. The speed limiter 8 limits the speed of the idler roller assembly 2 when needed to improve adaptability. The limit baffle 10 and the buffer spring 11 improve the stability and safety of the entire equipment. The installation method mainly uses the clamping buckle with screw holes to fasten to the foot plate of the idler roller assembly and the intermediate frame. After adjusting the position of the idler roller assembly with bolts, the nuts are locked to prevent loosening.
