Description
Technical Field
The utility model relates to a mechanical conveying mechanism technical field especially relates to a chain arrangement is carried to the oilless formula of chain scraper conveyor.
Background
The chain plate type conveying belt consists of a plurality of chain plates, two sides of the conveying belt are connected with a conveying chain, and the conveying belt moves under the traction of the chain. The rollers and rollers of the conveyor chains of large conveyor belts are made of steel, and lubricating oil needs to be added to the chains in order to reduce the abrasion of the rollers and rollers. However, for chemical fiber, tobacco and other products, the interior of heating equipment such as a dryer is easily contaminated by the volatile lubricant oil, so that a lubricant-free chain is required. In order to avoid using lubricating oil, a polymer bushing can be added between the roller and the roller of the chain, but the strength of the polymer bushing is not enough to bear the pressure when the roller of the chain is meshed with the chain wheel.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, a chain device is carried to the oilless formula of chain scraper conveyor is provided, through external gyro wheel cooperation from the sub-axle sleeve, avoid the contact wear of chain and increase the lubricating oil lubrication.
The utility model adopts the technical proposal that:
the oil-free conveying chain device of the chain plate conveyor is characterized by comprising a conveying belt and conveying chains on two sides, wherein the conveying belt is connected with the conveying chains, externally-hanging rollers are arranged on chain links of the conveying chains, the externally-hanging rollers are arranged on the outer sides of the conveying chains, a track is arranged below the externally-hanging rollers, and the externally-hanging rollers roll on the track during transmission of the conveying chains.
Further, each externally hung roller is arranged on each chain link of the chain.
Further, the central shaft of the externally hung roller is coaxial with the chain link of the conveying chain.
Furthermore, the externally hung idler wheel is arranged on the central shaft through a polymer shaft sleeve.
Further, an inner roller is arranged in the middle of the chain link, and a metal shaft sleeve is arranged on the inner roller.
Furthermore, two side edges of the externally-hung idler wheel are provided with check rings.
Further, the outer diameter of the externally hanging roller is larger than that of the chain link.
The utility model has the advantages that:
(1) the externally hung roller does not need to use lubricating oil, the chain does not generate contact wear, the lubricating oil can be eliminated, and the product is prevented from being polluted by the lubricating oil;
(2) the service life of the chain is prolonged, and the quality of the product is ensured.
(3) Simple structure and convenient installation.

Detailed Description
The following describes in detail a specific embodiment of the oilless conveying chain device of the chain conveyor according to the present invention with reference to the drawings.
Referring to the attached drawing 1, the oilless conveying chain device of the chain plate conveyor comprises a conveying belt and conveying chains 1 on two sides, the conveying belt is connected with the conveying chains 1 through connecting parts 2, external rollers 4 are arranged on chain links 3 of the conveying chains 1, the external rollers 4 are arranged on the outer sides of the conveying chains 1, a track 5 is arranged below the external rollers 4, and when the conveying chains 1 are driven, the external rollers 4 roll on the track 5. The externally hanging rollers 4 have an outer diameter larger than that of the links 3 so as not to cause interference of the links 3 with the rails 5. Externally hung rollers 4 are provided on each link 3 of the chain to ensure the weight bearing of the conveyor belt. Of course, a spacing design may also be provided.
Referring to the attached figure 2, a central shaft 7 of the externally-hung roller 4 is coaxial with a chain link 3 of the conveying chain 1, and is arranged on the central shaft 7 through a polymer shaft sleeve 6, and two side edges of the externally-hung roller 4 are provided with retaining rings 8. The middle of the chain link 3 is provided with an inner roller 9, and the inner roller 9 is provided with a metal shaft sleeve 10.
When the conveying device works, the chain wheel 11 drives the conveying chain 1 to convey, so that the externally-hung idler wheel 4 rolls forwards on the track 5, and the conveying belt connected to the conveying chain 1 is conveyed forwards. The inner rollers in the middle of the conveyor chain have almost no rotation.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
