Description

TECHNICAL FIELD

[0001] The utility model relates to a conveying line, in particular to a supporting device for slidingly supporting a large-span driving chain. BACKGROUND

[0002] The conveying line is used for conveying articles over a long distance, and the structure of the conveying line comprises at least two sprockets, which are arranged apart from each other. A driving chain is lapped on the sprockets. A plurality of driving members extending outward are arranged on the driving chain. The driving members can be rod-type driving rods or driving hooks. A guide rail is arranged below the driving chain and is arranged in parallel with the driving chain. A carrier runs on the guide rail. The driving members are driven by the driving chain to drive the carrier to run on the guide rail. In order to realize long-distance transmission, the spacing between the sprockets is relatively large, and the span of the driving chain between the sprockets is relatively large. In order to ensure that the driving chain has a certain straightness, a straight supporting rail is usually arranged between the sprockets to slidingly support the driving chain. The supporting rail is usually made of plastic, and the driving chain is made of iron. During the sliding support of the driving chain by the supporting rail, the driving chain will cause a certain amount of wear to the supporting rail. The wear process will generate a certain amount of dust. Initially, the dust will adhere to the driving chain or the supporting rail. As the dust accumulates, the dust will fall downward. Sometimes, the dust will fall onto the carried objects carried by the carrier, and it is inconvenient to clean the dust adhered to the carried objects. Therefore, the driving chain or the supporting rail needs to be cleaned to remove the adhered dust every time the conveying line is operated for a period of time, which increases the labor cost. SUMMARY

The utility model is characterized in that a dust collecting cavity is arranged on each of the opposite sides of the supporting rail in the width direction. The dust collecting cavity protrudes outward from the supporting surface and extends along the length direction of the supporting rail. The dust collecting cavity is in communication with the supporting surface and is used to collect the dust generated by the sliding friction between the driving chain and the supporting rail.

[0005] The powder collecting cavity has a certain volume to collect the powder produced by the friction between the driving chain and the support rail during the operation of the conveying line. The powder in the powder collecting cavity also needs to be cleaned at intervals.

[0009] Further, the upper end surface of the extension piece is located below the support surface. Under the premise of ensuring the collection of the produced powder, the resistance of the driving chain during operation can be reduced, and the installation between the driving chain and the support rail can be facilitated.

[0010] Further, the back surface of the sprocket is provided with a fixing part, the fixing part is provided with a covering piece, the covering piece is in an inverted "U" shape, the covering piece extends towards the front surface of the sprocket, the driving chain is lapped on the sprocket from the interval between the covering piece and the sprocket, and the two ends of the covering piece extend into the positions of the same side ends of the two support rails. The covering piece generally extends along the circumference of the fixing part. Through the arrangement of the covering piece, on the one hand, dust prevention can be provided for the driving chain, and on the other hand, the powder in the powder collecting cavity carried out by the driving chain can be received.

[0011] Further, the fixing part is provided with a through mounting opening, the mounting opening is open towards the support rail, a fixed plate is fixed on the back surface of the fixing part, and the wheel shaft of the sprocket is fixed on the fixed plate through the mounting opening. Through the arrangement of the fixed plate, the installation of the fixing part and the wheel shaft of the sprocket is realized, which is simple in structure and convenient to install.

This makes the end surface of the mounting table abut against the structure at the end of the support rail, and improves the effect of collecting the dust. The mounting table is arranged on the basis of ensuring the connection strength between the fixing plate and the fixing part, and can effectively reduce the material consumption of the fixing part.

[0013] Compared with the prior art, the utility model has the beneficial effects that: by setting the dust collecting cavity on the opposite two side surfaces of the support rail, the dust generated by the friction of the driving chain on the support rail during sliding can be collected, the falling of the dust on the carried objects carried by the carrier can be effectively prevented, and the carried objects can be kept clean. Although the collected dust in the dust collecting cavity needs to be cleaned, the cleaning interval is relatively long, the number of times of cleaning the dust in the running cycle of the conveying line can be reduced, and the labor cost can be effectively reduced.
