Abstract
The utility model relates to a kind of isosceles triangle heavy carrier roller group.The side roller (1) comprising both sides and two middle idler rollers (2) be arranged between two side rollers (1), the both sides being arranged on two side rollers (1) that two middle idler rollers (2) are symmetrical; Establish horizontally disposed back plate (3) between two middle idler rollers (2), back plate (3) maintains static, and back plate (3) upper surface and two middle idler rollers (2) end face flush.The utility model has the advantages that: 1) the utility model respectively designs a middle idler roller in both sides in the middle of two side roller line of centerss, considerably increase idler machining load-carrying capacity, simultaneously due to two side rollers and two middle idler rollers not point-blank, four rollers are stressed is tending towards balanced, improves the service life of middle idler roller.Middle two middle idler rollers form a plane with two side rollers, greatly reduce the contact of side roller edge with adhesive tape like this, thus effectively prevent the generation of side roller edge torn adhesive tape accident, improve the service life of adhesive tape.
Description
Technical field
The utility model relates to a kind of isosceles triangle heavy carrier roller group, belongs to conveyer technical field.
Background technology
Support roller for belt machine group is the vitals of composition belt feeder, and support belt and material above reduce the sag of belt, ensure belt smooth running, there being a year branch shape to become grooved zone face, can increasing operational throughput and preventing material both sides from spilling.A conveyer carrying roller group quantity is a lot, the version of idler machining, and to the running resistance of conveyer, in the life-span of load-transfer device, energy ezpenditure and maintenance, over-the-road expense etc. affect very large.
In traditional isosceles triangle idler structure, central roll and limit roller are not point-blank, middle is empty with limit roller position point-blank, centre only has a middle idler roller in the side at side roller center, such adhesive tape is under material gravity effect, adhesive tape adhesive tape non-working surface in operational process marks two zanjons on side roller edge, largely will reduce the service life of adhesive tape.
Gap simultaneously between two adjacent middle idler rollers is also the weak part of conveyer, because lack support herein, form neutral, although the spacing between two adjacent middle idler rollers is less, but the gap of centre is still to having a negative impact the service life of conveyer, particularly when carrying heavier material, seem especially obvious.
Utility model content
The utility model is for above-mentioned defect, and object is to provide the isosceles triangle heavy carrier roller group that a kind of structure is simple, energy actv. improves adhesive tape force environment.
The technical solution adopted in the utility model is for this reason: the side roller (1) that the utility model comprises both sides and two middle idler rollers (2) be arranged between two side rollers (1), the both sides being arranged on two side rollers (1) that two middle idler rollers (2) are symmetrical; Establish horizontally disposed back plate (3) between two middle idler rollers (2), back plate (3) maintains static, and back plate (3) upper surface and two middle idler rollers (2) end face flush.
Described back plate (3) upper surface is plane, and be arranged in the gap of formation between two middle idler rollers (2), two middle idler rollers (2) of getting along well produce contact.
The utility model has the advantages that: 1) the utility model respectively designs a middle idler roller in both sides in the middle of two side roller line of centerss, considerably increase idler machining load-carrying capacity, simultaneously due to two side rollers and two middle idler rollers not point-blank, four rollers are stressed is tending towards balanced, improves the service life of middle idler roller.Middle two middle idler rollers form a plane with two side rollers, greatly reduce the contact of side roller edge with adhesive tape like this, thus effectively prevent the generation of side roller edge torn adhesive tape accident, improve the service life of adhesive tape; 2) the utility model arranges back plate between two adjacent middle idler rollers, clearance filled by what formed between two middle idler rollers, therefore improve the support degree to adhesive tape, improve the service life of adhesive tape, back plate arranges motionless its and only plays supporting role, can not bring any impact to the operation of adhesive tape.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 be side roller, 2 be middle idler roller in figure, 3 be back plate, 4 for radiating groove.
Detailed description of the invention
The utility model comprises the side roller 1 of both sides and is arranged on the both sides being arranged on two side rollers 1 of two middle idler roller 2, two middle idler roller 2 symmetries between two side rollers 1; Establish horizontally disposed back plate 3 between two middle idler rollers 2, back plate 3 maintains static, and back plate 3 upper surface and two middle idler roller 2 end faces flush.
Described back plate 3 upper surface is plane, is arranged in the gap of formation between two middle idler rollers 2, and two middle idler rollers 2 of getting along well produce contact.
The utility model offers radiating groove 4 at back plate 3 upper surface, contacts because back plate 3 remains with adhesive tape, and both are cliding friction, and its heat produced is more, therefore by offering radiating groove distribute heat.
The utility model can apply heat dissipating layer further at the upper surface of back plate 3, to improve heat dispersion further, due to the existence of back plate 3, can overcome Classical adhesive tape and press down the defect causing the stressed increase of middle idler roller 2; Therefore the existence of back plate 3 not only improves the force environment of adhesive tape, also improves the force environment of middle idler roller 2 simultaneously, reduces the friction force between middle idler roller 2 and adhesive tape, can improve the service life of middle idler roller 2.
Claims (2)
1. isosceles triangle heavy carrier roller group, is characterized in that, the side roller (1) comprising both sides and two middle idler rollers (2) be arranged between two side rollers (1), the both sides being arranged on two side rollers (1) that two middle idler rollers (2) are symmetrical; Establish horizontally disposed back plate (3) between two middle idler rollers (2), back plate (3) maintains static, and back plate (3) upper surface and two middle idler rollers (2) end face flush.
2. isosceles triangle heavy carrier roller group according to claim 1, is characterized in that, described back plate (3) upper surface is plane, and be arranged in the gap of formation between two middle idler rollers (2), two middle idler rollers (2) of getting along well produce contact.
