Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a 90-degree turning roller conveyor. Background Technology

[0002] Roller turning conveyors are widely applicable and can be used to transport various boxes, bags, pallets and other items. Bulk materials, small items or irregular items need to be placed on pallets or in turnover boxes for angled turning and transport. However, in existing conveyors, the rollers are driven by multi-stage chains and sprockets. If one of the chains becomes loose during operation, the conveyor cannot be transported, resulting in a high failure rate. In addition, during the turning and transporting process, the goods are easily deviated from the outer edge by centrifugal force, and may even detach from the outer edge of the roller. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a 90-degree turning roller conveyor.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a 90-degree turning roller conveyor, comprising an arc-shaped base frame, on which are arranged a plurality of arc-shaped conical rollers, forming a turning conveyor channel between the rollers. Limiting strips are fixed to both sides of the base frame via fixing frames, forming a limiting channel between two limiting strips for limiting the conveyed items. The base frame is provided with a drive mechanism that drives each conical roller to rotate, and the drive mechanism includes a driven bevel gear at the end of each conical roller. A transmission shaft corresponding to each conical roller is installed on the side of the base frame, and the transmission shafts are connected to form a drive shaft via a universal coupling. Each transmission shaft is equipped with a drive bevel gear that meshes with the driven bevel gear. The base frame is provided with a drive motor that drives the drive shaft to rotate.

[0006] As a preferred technical solution of this utility model, the side end of the base frame is provided with an inwardly recessed groove for accommodating the drive shaft, driven bevel gear, and driving bevel gear, and the surface of the groove is provided with a dustproof cover.

[0007] As a preferred embodiment of this utility model, the upper and lower sides of the groove are provided with bending plates that bend inward toward the groove, and the dust cover is fixed to the bending plates by bolts.

[0008] As a preferred technical solution of this utility model, both ends of the limiting stop bar are provided with guide plates that are arranged to open outwards.

[0009] As a preferred embodiment of this invention, the surface of the conical roller is provided with anti-slip texture.

[0010] In a preferred embodiment of this invention, the drive motor is a geared motor.

[0011] As a preferred embodiment of this utility model, the transmission shaft is mounted on the side of the base frame via a bearing seat.

[0012] As a preferred embodiment of this utility model, the conical roller includes a hollow shaft, with a large positioning plate and a small positioning plate respectively provided at both ends of the hollow shaft. A fan-shaped surrounding plate is provided on the large positioning plate, and the fan-shaped surrounding plate is arranged around the large and small positioning plates to form a roller surface, so that the hollow shaft is fixedly supported by a bracket that supports the bottom surface of the fan-shaped surrounding plate. A central shaft is installed inside the hollow shaft, and the central shaft is fixedly connected to the driven bevel gear.

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

[0014] This type of 90-degree turning roller conveyor has drive shafts installed on the sides of the base frame, each corresponding to a conical roller. The drive shafts are connected by universal couplings to form a drive shaft. Each drive shaft is equipped with a drive bevel gear that meshes with a driven bevel gear. When the drive motor rotates the drive shaft, the drive bevel gear on the drive shaft meshes with the driven bevel gear, driving each conical roller to work independently. This prevents the normal operation of other conical rollers from being affected by the abnormality of one conical roller. Limiting bars are fixed on both sides of the base frame via fixing frames. The two limiting bars form a limiting channel for limiting the conveyed items, thus preventing them from slipping off. Attached Figure Description

[0021] 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.

[0022] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a 90-degree turning roller conveyor, including an arc-shaped base frame 1. The base frame 1 is provided with several arc-shaped conical rollers 2, forming a turning conveyor channel between the rollers. Limiting strips 4 are fixed to both sides of the base frame 1 via fixing frames 3, forming a limiting channel between two limiting strips 4 for limiting the conveyed items. The base frame 1 is provided with a drive mechanism that drives each conical roller 2 to rotate, and the drive mechanism includes a driven bevel gear 5 at the end of each conical roller 2. A transmission shaft 6 corresponding to each conical roller 2 is installed on the side of the base frame 1. The transmission shafts 6 are connected by a universal coupling 7 to form a drive shaft. Each transmission shaft 6 is equipped with a drive bevel gear 8 that meshes with the driven bevel gear 5. The base frame 1 is provided with a drive motor 9 that drives the drive shaft to rotate. A drive shaft 6, corresponding to each conical roller 2, is installed on the side of the base frame 1. The drive shafts 6 are connected by a universal coupling 7 to form a drive shaft. Each drive shaft 6 is equipped with a drive bevel gear 8 that meshes with the driven bevel gear 5. When the drive shaft is rotated by the drive motor 9, the drive bevel gear 8 on the drive shaft 6 meshes with the driven bevel gear 5, driving each conical roller 2 to work independently. This prevents the normal operation of other conical rollers 2 from being affected by the abnormality of one conical roller 2. Limiting bars 4 are fixed on both sides of the base frame 1 by fixing brackets 3. The two limiting bars 4 form a limiting channel for limiting the conveyed items, thus preventing them from slipping off.

[0023] The base frame 1 has an inwardly recessed groove 10 on its side end for housing the drive shaft 6, driven bevel gear 5, and driving bevel gear 8. The surface of the groove 10 is provided with a dustproof cover 11, which serves two purposes: dust prevention and easy disassembly for maintenance of the driven bevel gear 5 and driving bevel gear 8.

[0024] The groove 10 has bending plates 12 on its upper and lower sides that bend inward toward the groove 10. The dust cover 11 is fixed to the bending plates 12 with bolts, which facilitates disassembly for maintenance of the driven bevel gear 5 and the driving bevel gear 8.

[0025] The limiting barrier 4 has guide plates 13 that open outwards at both ends, which facilitates the entry of items into the limiting channel.

[0026] The tapered roller 2 has anti-slip texture 14 on its surface, which increases the surface friction of the tapered roller 2 and facilitates the transportation of goods.

[0027] The conical roller 2 includes a hollow shaft 201. A large positioning plate 202 and a small positioning plate 203 are respectively provided at both ends of the hollow shaft 201. A fan-shaped surrounding plate 204 is provided on the large positioning plate 202. The fan-shaped surrounding plate forms a roller surface around the large positioning plate 202 and the small positioning plate 203. A bracket 206, which supports the bottom surface of the fan-shaped surrounding plate 204, is provided on the hollow shaft 201 via a fixing frame 205. A central shaft 207 is installed inside the hollow shaft 201 and is fixedly connected to the driven bevel gear 5. This makes the conical roller 2 hollow, reducing the overall mass and effectively reducing the load on the transmission shaft. This facilitates the drive motor to drive each conical roller 2, reducing the power requirements of the drive motor. The bracket supports the bottom surface of the fan-shaped surrounding plate 204, making it less prone to deformation during object transport.

[0028] During operation, this type of 90-degree turning roller conveyor has a drive shaft 6 installed on the side of the base frame 1, corresponding to each conical roller 2. The drive shafts 6 are connected by a universal coupling 7 to form a drive shaft. Each drive shaft 6 is equipped with a drive bevel gear 8 that meshes with the driven bevel gear 5. When the drive shaft is rotated by the drive motor 9, the drive bevel gear 8 on the drive shaft 6 meshes with the driven bevel gear 5, driving each conical roller 2 to work independently. This prevents the normal operation of other conical rollers 2 from being affected by the abnormality of one conical roller 2. Limiting bars 4 are fixed on both sides of the base frame 1 by fixing frames 3. The two limiting bars 4 form a limiting channel for limiting the conveyed items, thus preventing them from slipping off.

[0029] 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.
