[0002] Chain conveyor: also called chain conveyor, chain line. It is a kind of conveying mechanical equipment that uses a reciprocating chain as traction power and a metal plate as a conveying carrier. There are two types of chain conveyors on the domestic market. One is a conveyor made of a conveying chain composed of a chain, a support shaft and a metal plate; the other is a chain conveyor made of a metal plate conveyor belt composed of a chain with a bent plate and a metal plate.

[0003] The traditional chain plate transmission method is to move the chain plate on the surface of the profile. When the conveying direction of the chain plate needs to be changed through the arc profile, the sliding friction between the chain plate and the profile increases when the chain plate moves at a corner, which easily accelerates the wear of the chain plate and reduces the service life of the chain plate. For this reason, a low-friction horizontal bending wheel is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a low-friction horizontal bending wheel to solve the problem that the traditional chain plate transmission method proposed in the above-mentioned background technology is that the chain plate moves on the surface of the profile. When the conveying direction of the chain plate needs to be changed through the arc profile, the sliding friction between the chain plate and the profile increases when the chain plate moves at a corner, which easily accelerates the wear of the chain plate and reduces the service life of the chain plate.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-friction horizontal bending wheel, comprising a fixed shaft, the outer sides of which are respectively sleeved with a first connecting frame and a second connecting frame, the first connecting frame and the second connecting frame are fixedly connected to a connecting block at one end away from the fixed shaft, a slot is provided at one end of the connecting block, the outer side of the fixed shaft is located on both sides of the first connecting frame and the second connecting frame, two bearings are fixedly sleeved at the outer sides of the two bearings, and arc profiles are provided on the outer sides of the two connecting blocks, and slots are provided on the inner sides of the arc profiles.

[0006] As a further preferred embodiment of the technical solution: a convex strip is provided on the inner side of the arc-shaped profile, and the convex strip is engaged with the inside of the card slot.

[0007] As a further preferred embodiment of the technical solution: a mounting hole is provided on the disc, the two bearings are fixedly connected to the inside of the mounting hole, and a cover is connected to the outside of the mounting hole.

[0008] As a further preferred embodiment of the present technical solution: guide columns are fixedly connected to both the first connecting frame and the second connecting frame.

[0010] As a further preferred embodiment of the technical solution: a chain plate is arranged between the arc-shaped profile and the disc, and the bosses at both ends of the bottom of the chain plate are respectively located inside the limiting groove and below the disc.

[0011] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model installs the bottom of the chain plate inside the limit groove and under the disc, and the chain plate moves on the top of the arc profile. At this time, the chain plate moves on the top of the disc, and at the same time, the chain plate drives the disc to rotate on the outside of the fixed shaft, so that the sliding friction between the chain plate and the disc is transformed into rolling friction, reducing the friction force, thereby increasing the service life of the chain plate and the designable length of the conveyor line, and saving more space.

[0023] In order to install the arc profile 12; a convex strip 13 is provided on the inner side of the arc profile 12, and the convex strip 13 is clamped in the inside of the slot 6; a mounting hole 10 is provided on the disc 8, and the slot 6 fixes the ninety-degree arc profile 12 through the setting of the connecting block 5 on the first connecting frame 2 and the second connecting frame 3, so that the installation of the arc profile 12 can be completed; the two bearings 4 are fixedly connected to the inside of the mounting hole 10, and the outer side of the mounting hole 10 is connected to the cover body 11, and the setting of the bearing 4 can make the disc 8 rotate; the first connecting frame 2 and the second connecting frame 3 are fixedly connected with the guide column 7, and the setting of the guide column 7 can guide the chain plate 18; a connecting strip 15 is movably inserted into the interior of the slot 14, and a connecting hole 16 is opened on the connecting strip 15, and it can be connected to the conveying beam through the connecting strip 15, which is simple and convenient.
