Description

Technical Field

[0001] This utility model relates to the field of roller conveyor technology, specifically a roller conveyor that can achieve stable transportation of objects. Background Technology

[0002] Roller conveyors are suitable for conveying various boxes, bags, pallets, and other packaged goods. Bulk materials, small items, or irregularly shaped items need to be placed on pallets or in turnover boxes for transport. Roller conveyors can transport materials with large single-item weights or withstand large impact loads. Roller lines are easy to connect and transition, and multiple roller lines can be combined with other conveyors or special machines to form complex logistics conveying systems to meet various process requirements.

[0003] Chinese Patent Application No. CN201821960268.X discloses a roller for a roller conveyor, relating to the field of logistics equipment. It includes an intermediate shaft with an annular placement groove containing a rubber pad. When the rubber pad is enclosed in the groove, its outer wall is flush with the outer wall of the intermediate shaft, and the long sides of the pad abut against each other. The intermediate shaft has a fixing element to secure the rubber pad within the groove. This roller can reduce collisions between rollers when heavy goods are placed on it, thus protecting the rollers. However, the following technical problems still exist: 1. The multiple sprockets coaxial with the rollers are driven by the same chain; when the chain loosens, the sprockets in the middle area cannot rotate; 2. Gaps exist between adjacent rollers, making it prone to bumping and shaking when conveying small-volume goods, and easily damaging fragile goods. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a roller conveyor that enables smooth transport of objects.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a roller conveyor for stable transport of objects, comprising a support frame, with multiple equally spaced rollers at the top of the support frame, each roller having a sprocket at the same end, the sprockets being connected by a chain drive, and a tensioning assembly for tensioning the chain at one end of the support frame; the tensioning assembly includes a mounting plate inclined downward at one end of the support frame, a guide wheel and a tensioning wheel for guiding the chain drive on the mounting plate, a cross-shaped guide groove on the mounting plate, a guide slider slidably connected in the guide groove, the tensioning wheel being connected to the guide slider via a rotating shaft, and a tensioning spring connected to the guide slider in the guide groove.

[0007] As a preferred embodiment of this utility model, the mounting plate is provided with an adjustment component for adjusting the tensioning component.

[0011] As a preferred technical solution of this utility model, the elastic connector includes a support rod disposed on the support frame and located between two adjacent rollers, and an elastic plastic sleeve is provided on the outside of the support rod located above the support rod.

[0012] As a preferred technical solution of this utility model, the elastic connecting member may also include 2-4 support cylinders connected to the support frame by bearings and located between two adjacent rollers. The outer diameter of the multiple support cylinders is smaller than the outer diameter of the rollers, and the height of the top of the support cylinder is equal to or lower than the height of the top of the rollers.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of roller conveyor, which enables smooth transport of objects, has a tensioning component that effectively tensions the chain, preventing the sprocket in the middle area from becoming unable to rotate due to chain loosening, thus ensuring the normal transport of objects by the roller conveyor. Specifically, when the sprocket becomes loose, the tensioning spring causes the guide slider to move downward along the guide groove, and the wire slider drives the tensioning wheel downward, thereby tightening the loose sprocket.

[0015] 2. This type of roller conveyor that enables smooth transport of objects involves rotating a reference wheel, which drives an adjusting screw to rotate. The adjusting screw is threadedly connected to a mounting plate, and the end of the adjusting screw is connected to an adjusting block via a bearing. The adjusting block matches a guide groove, allowing the adjusting block to move along the guide groove, thereby adjusting the tension of the tensioning assembly.

[0016] 3. This type of roller conveyor, which enables the smooth transport of objects, uses elastic connecting parts to prevent small-volume goods from shaking or swaying during transport, thus avoiding damage to fragile goods and ensuring smooth transport of goods between adjacent rollers.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model discloses a roller conveyor capable of smoothly transporting objects, comprising a support frame 1. Multiple rollers 2 are equidistantly distributed at the top of the support frame 1. Each roller 2 has a sprocket 3 at the same end, and the sprockets 3 are connected by a chain 4. One end of the support frame 1 is provided with a tensioning assembly 5 for tensioning the chain 4. The tensioning assembly 5 includes a mounting plate 501 inclined downwards at one end of the support frame 1. The mounting plate 501 has a guide wheel 502 and a tensioning wheel 503 for guiding the chain 4. A cross-shaped guide groove 504 is formed on the mounting plate 501, and a guide wheel 503 is slidably connected within the guide groove 504. The tensioning wheel 503 is connected to the guide slider 505 via a rotating shaft. The guide groove 504 is equipped with a tensioning spring 506 connected to the guide slider 505. Through the tensioning assembly 5, the chain 4 can be well tensioned, preventing the sprocket 3 in the middle area from not rotating after the chain 4 becomes loose, thus ensuring the normal transport of objects by the roller conveyor 2. When the sprocket 3 becomes loose, the tensioning spring 506 will cause the guide slider 505 to move downward along the guide groove 504. The guide slider will drive the tensioning wheel 503 to move downward, thus tightening the loose sprocket 3.

[0026] The mounting plate 501 is provided with an adjustment component 6 for adjusting the tensioning component 5. The adjustment component 6 includes an adjustment block 601 that is disposed in and slides within the guide groove 504 and matches the guide groove 504. An adjustment screw 602 is threadedly connected to the mounting plate 501 and connected to the adjustment block 601 via a bearing. The outer end of the adjustment screw 602 is provided with a rotating wheel 603. Rotating the rotating wheel causes the rotating wheel 603 to drive the adjustment screw 602 to rotate. The adjustment screw 602 is threadedly connected to the mounting plate 501. Since the end of the adjustment screw 602 is connected to the adjustment block 601 via a bearing, the adjustment block 601 matches the guide groove 504, allowing the adjustment block 601 to move along the guide groove 504, thereby adjusting the tension of the tensioning component 5.

[0027] During operation, this roller conveyor 2, which enables smooth transport of objects, uses a tensioning component 5 to effectively tension the chain 4, preventing the sprocket 3 in the middle area from becoming unable to rotate due to chain 4 loosening, thus ensuring the normal transport of objects by the roller conveyor 2. Specifically, when the sprocket 3 becomes loose, the tensioning spring 506 causes the guide slider 505 to move downward along the guide groove 504, and the wire slider drives the tensioning wheel 503 to move downward, thereby tightening the loose sprocket 3.

[0028] Example 2, as Figure 1 and Figure 4As shown, a further improvement has been made based on Embodiment 1. The support frame 1 is provided with an elastic connector 7 located between two adjacent rollers 2. The elastic connector 7 includes a support rod 701 provided on the support frame 1 and located between two adjacent rollers 2. An elastic plastic 702 is sleeved on the outside of the support rod 701 and located above the support rod 701. With the provided elastic connector 7, small-volume goods are less likely to be bumped or shaken during transportation, avoiding damage to fragile goods during transportation, and ensuring that the goods are transported smoothly between adjacent rollers 2. The elastic plastic 702 can play a good protective role for fragile goods during transportation.

[0029] Example 3, as Figure 2 and Figure 5 As shown, the technical feature that differs from Embodiment 2 is that the support frame 1 is provided with an elastic connecting member 7 located between two adjacent rollers 2. The elastic connecting member 7 may also include 2-4 support cylinders 703 connected to the support frame 1 via bearings and located between two adjacent rollers 2. The outer diameter of the multiple support cylinders 703 is smaller than the outer diameter of the rollers 2, and the height of the top of the support cylinder 703 is equal to or lower than the height of the top of the rollers 2. With the provided elastic connecting member 7, small-volume goods are less likely to be bumped or shaken during transportation, avoiding damage to fragile goods during transportation, ensuring that the goods are transported smoothly between adjacent rollers 2, and the support cylinders 703 make the transportation of goods smoother.

[0030] 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.
