Description

A kind of roller conveyor of scalable fed distance

One. technical field

The utility model relates to a kind of roller conveyor of scalable fed distance, particularly a kind of mechanism that can regulate fed distance on the roller conveyor that is installed in, and the roller conveyor of a kind of scalable fed distance of the utility model belongs to field of transport machinery.

Two. background technology

Roller conveyor is when conveying articles, and along with the stacking of goods, the distance that usually need regulate conveying changes break bulk point; Existing roller conveyor is adopt to change between the carrying roller distance to extend or shortens the distance of carrying, but in the design of roller conveyor, distance is to determine according to the physical property that is transferred goods between the adjacent carrying roller; After the distance, make the roller conveyor conveying articles receive certain restriction between the variation carrying roller, especially when carrying packed bulk cargo; The influence that receives external force owing to bulk cargo in the bag is flowed; Changed the shape of outer bag, in course of conveying, produced situation such as Ka Bao, so that carry failure.

Three. summary of the invention

The utility model is a kind of roller conveyor of scalable fed distance, and conveyer is made up of canned paragraph and active segment two major parts, and canned paragraph frame 3 is as the frames of whole conveyer; The height of canned paragraph frame leg 1 is adjustable respectively; The height of adjustment frame leg 1 can satisfy different conveying inclination angles, and the carrying roller 2 of canned paragraph is installed on the canned paragraph frame 3, and active segment carrying roller 8 is attached on the chain 10 with locating wheel 9; Locating wheel 9 is controlled on the active segment frame motion in 12 the guide groove 11; The track that active segment frame 12 moves forward and backward is formed in canned paragraph, active segment two frames and directed cooperation with sliding

wheel

4 and 7, and active segment has preceding sprocket wheel 13, back sprocket wheel 5, and each is a pair of, and forward and backward sprocket wheel passes through sprocket shaft, bearing and 12 connections of active segment frame; Forward and backward sprocket wheel can rotate around sprocket shaft; Chain 10 two ends are fixed on the upper end of canned paragraph frame 3 through chain coupling seat 6, and when moving active segment frame 12, forward and backward sprocket wheel is forced to rotate by mechanism; Chain 10 with locating wheel 9 in guide groove 11, move, the carrying roller 8 of active segment, locating wheel 9 advance thereupon, retreat; Thereby the quantity of the carrying roller 8 of the active segment of control active segment participation work, pull bar 15 is fixed on the head of active segment frame 12, the moving forward and backward of handled easily active segment frame 12.

The canned paragraph carrying roller 2 of the utility model is installed on the fixed frame, vertically open slotted hole on the frame and be convenient to canned paragraph carrying roller 2 and install, and the card of being furnished with 2 of fixing canned paragraph carrying rollers is located with screw.

There is the orientation that moves forward and backward of control movable machine frame front portion on the canned paragraph frame 3 of the utility model with sliding wheel 7; Directed with the stationkeeping of sliding wheel 7 on canned paragraph frame 3; Only can rotate, directed is restraint section frame 12 forward and backward mobile extreme positions with sliding wheel 7 another effects.

On the canned paragraph frame 3 of the utility model position-arresting device 16 has been installed, confirm the control position of active segment frame 12 after, position-arresting device 16 stop bits and fixing active segment frame 12 no longer receive external action.

The middle part of the active segment frame about 12 of the utility model has slotted hole; The directed insertion with sliding wheel (7) worked therebetween; Respectively installed rotary directed about the rear portion of active segment frame (12) with sliding wheel 4; Directed insert in the slotted hole of canned paragraph frame 3 when the general assembly with sliding wheel 4, canned paragraph frame 3, active segment frame 12, the directed composition jointly with sliding wheel 4, position-arresting device 16 with sliding wheel 7, orientation can be controlled the track that active segment frame 12 moves forward and backward.

The active segment of the utility model has preceding sprocket wheel 13 back sprocket wheels 5, and each is a pair of; Forward and backward sprocket wheel connects through sprocket shaft, bearing and active segment frame 12; Forward and backward sprocket wheel can rotate; Chain 10 is after forward and backward sprocket wheel, and two ends of chain 10 are fixed on the nock of canned paragraph frame 3 through chain coupling seat 6.

The active segment carrying roller 8 of the utility model is installed on the chain 10 through locating wheel 9; Be arranged in the first half of chain-wheel mechanism; Establish a fixing carrying roller 14 in addition at the head of active segment frame 12, the head of active segment install one fixedly carrying roller be to be used for eliminating conveying dead angle in preceding sprocket wheel 13 arc transition sections.

The guide groove 11 of the utility model is fixed on the active segment frame 12, and locating wheel 9 is driven by chain 10, and is limited in 11 motions in the guide groove, thereby has limited beating of chain 10 and active segment carrying roller 8 above-below directions.

The improvement of the utility model is seesawing through active segment frame 12; Drive corresponding chain-wheel mechanism, the fed distance that the quantity of the active segment carrying roller 8 of change participation work is regulated conveyer, distance remains unchanged between the carrying roller; The conveyor surface of canned paragraph and active segment is consistent; After having adopted chain-wheel mechanism, this roller conveyor can change the distance of carrying arbitrarily in certain scope, at the driving surface of active segment except that the active segment carrying roller 8 of needs participation work; Unnecessary active segment carrying roller 8 is transferred to the lower part of chain-wheel mechanism with chain 10, and whole roller conveyor structure is simplified widely.
