Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology and relates to a ring flexible chain conveyor for conveying cardboard boxes. Background Technology

[0002] The circular flexible chain conveyor is a high-efficiency and flexible material conveying equipment, especially suitable for conveying regularly shaped items such as cardboard boxes.

[0003] Chinese patent publication number CN215401183U discloses a flexible chain conveyor. A fixed frame is mounted on the upper side of a column and connected to the column by bolts. Joints are located on the upper and lower sides of the fixed frame, forming an integral structure. Pads are located on the outer side of the joints and are snapped into place. Multiple straightening gears are located inside the pads. A rotating roller is connected to the fixed frame, and a drive gear is located on the outer side of the rotating roller and connected to it via a flat key. A chain is positioned in the middle of the rotating roller and sleeved with it. A limiting rod is located on the inner side of the chain and connected to it by bolts. A reduction motor is located on the front right side of the fixed frame and connected to it by bolts.

[0004] The patent provides a flexible chain conveyor with a limiting rod set inside the chain belt. Although this can limit the position of the chain belt to a certain extent, there is no special guiding and protective structure for the conveyed items at the corners. In actual conveying, the items are prone to derailing from the conveyor track due to factors such as shaking and speed changes. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by providing a ring-shaped flexible chain conveyor for carton transport.

[0006] The objective of this utility model can be achieved through the following technical solution: A ring-shaped flexible chain conveyor for carton conveying, comprising a body assembly, a sprocket assembly, a guardrail assembly, and fixed feet. The body assembly includes a long body, a short body, and an arc-shaped body. The long and short bodies are elongated and spaced apart. A long conveying channel and a short conveying channel are respectively formed in the long and short bodies. The arc-shaped body is installed between the long and short bodies. The sprocket assembly includes a turntable or drive disc, chain teeth, a fixed block, and a connecting block. The fixing block is fixedly installed inside the turntable, and the connecting block is fixed on both sides of the fixing block. The connecting block is fixedly connected to the long body and the short body respectively. The arc-shaped body is fixedly connected to the outer side of the long body and the short body. The upper end of the chain tooth block is a chain tooth plate, and the two sides of the chain tooth plate are respectively attached to the upper end of the arc-shaped body and the turntable. The lower end of the chain tooth block forms a positioning cylinder. The guardrail assembly includes an annular guardrail and guardrail fixing parts. The annular guardrail is set on both sides of the upper end of the body assembly. A gap is left between the annular guardrail and the body assembly. The fixing foot is installed on the lower end of the body assembly.

[0007] In the above-mentioned annular flexible chain conveyor for carton conveying, the number of sprocket assemblies is four, the number of turntables is three and the number of drive discs is one, the fixing block is fixedly installed at the lower end of the drive disc, and the connecting block is fixed on both sides of the fixing block and fixedly connected to the long body and the short body respectively.

[0008] In the above-mentioned annular flexible chain conveyor for carton conveying, a flange body is fixedly connected to the lower end of the fixed block at the lower end of the drive disc, and a drive motor is fixedly connected to the lower end of the flange body. The drive motor extends with a drive shaft that passes through the flange body and is connected to the drive disc. Drive teeth are formed on the side end face of the drive disc, and the inner side of the positioning cylinder meshes with the drive teeth.

[0009] In the above-mentioned annular flexible chain conveyor for carton conveying, the upper end of the guardrail fixing member is connected to the annular guardrail, the lower end of the guardrail fixing member inside the body assembly is fixedly connected to the short body, and the lower end of the guardrail fixing member outside the body assembly is fixedly connected to the arc-shaped body.

[0010] In the aforementioned annular flexible chain conveyor for carton transport, the annular guardrail completely covers the short body and the arc-shaped body, extends out of the arc-shaped body, and is located on both sides of the upper end of the long body.

[0011] Compared with the prior art, the circular flexible chain conveyor for carton conveying provided by this utility model has the following beneficial effects: 1. The circular guardrail completely covers the short body and the arc-shaped body and extends to both sides of the long body, and the guardrail and the body components have reasonable gaps, which can effectively prevent the carton from leaving the track during conveying, and avoid interference between the circular guardrail and the body components or chain teeth blocks, thus improving the safety of the conveying process; 2. The upper chain teeth of the chain teeth block are attached to the arc-shaped body and the upper end of the turntable, and the lower positioning cylinder is engaged with the driving teeth of the drive disk. The double limiting structure ensures that the chain teeth block can run stably in both straight and turning sections, avoiding the carton from tipping over or colliding due to shaking or deviation during the conveying process.
