Relatively weak defect, the utility model provide a kind of compact-sized, the strong idle pulley strainer for being used to push away case of cushioning ability.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
It is a kind of that for pushing away the idle pulley strainer of case, the idle pulley strainer is arranged in the rack for pushing away draw box mechanism,
The rack includes the horizontal carrier bar positioned at the side plate of two sides and for carrier package object, is symmetrically arranged with wheel group on both side plate
Part, the wheel assembly include driving wheel, driven wheel and tensioning idle pulley, and the driving wheel, driven wheel and tensioning on each side plate are lazy
Wheel is sequentially connected by chain, and the push rod for pushing packing material is fixed on the chain, and the side plate is equipped with waist
Hole, the tensioning idle pulley wheel shaft can be slided along waist hole；
The idle pulley strainer includes tensioning screw and the tensioning screw support that is fixed on side plate, the tensioning
Screw rod one end is connected with tensioning idle pulley, and the tensioning screw support is equipped with first passed through for the tensioning screw other end and leads to
Hole has been threadedly engaged tensioning nut, the tensioning nut and tensioning screw in the two sides of through-hole on the tensioning screw
Cushion is equipped between support.
Further, the central axis of the tensioning screw and the length direction of waist hole are parallel.
Further, plain washer is equipped between the tensioning nut and cushion.
Further, the tensioning screw is described by tensioning folded plate and the wheel axis connection for being tensioned idle pulley
Being tensioned folded plate includes along the tensioning symmetrically arranged two L-type plates of idle pulley, and one end of L-type plate is equipped with the second through-hole, the wheel shaft
In be equipped with a bolt, also cross the second through-hole, the other end of L-type plate is equipped with to be passed through the bolt for tensioning screw
Third through-hole is threaded on the tensioning screw and two folded plate bottom ends is overlapped to fixed the first nut and the second spiral shell
It is female.
Further, the cushion is polyurethane cushion.
The utility model has the advantages that tensioning idle pulley and chain do not need too big tensile force, but right during pushing away case work
Damping property has certain requirement, compared to the strainer of original spring, the strainer of the utility model can with compared with
Small spatial volume meets tensioning needs, avoids cumbersome Spring Selection and calculates, while also compared with spring on damping performance
Formula strainer is more excellent, is more able to satisfy actual requirement.

Specific embodiment
Such as Fig. 1~3, a kind of for pushing away the idle pulley strainer of case, the rack for pushing away draw box mechanism is arranged in idle pulley strainer
On, rack includes the horizontal carrier bar positioned at the side plate 1 of two sides and for carrier package object, it is symmetrically arranged with wheel assembly on both side plate 1,
Wheel assembly includes driving wheel 9, driven wheel 10 and tensioning idle pulley 2, is connected with driving mechanism on driving wheel 10, driving mechanism is generally
Motor, driving wheel 9, driven wheel 10 and tensioning idle pulley 2 on each side plate 1 are sequentially connected by chain, and whole is not drawn into figure
Chain, is fixed with the push rod 8 for pushing packing material on chain, and the movement of chain-driving push rod 8 completes to push away case movement, on side plate 1
It equipped with waist hole, is tensioned in 2 wheel shaft of idle pulley and passes through a bolt, bolt slides in waist hole, and bolt end is combined with nut, tightens
Nut can be such that wheel shaft is against on the inner wall of side plate 1；
Idle pulley strainer includes tensioning screw 7 and the tensioning screw support 6 that is fixed on side plate 1,7 one end of tensioning screw
With tensioning idle pulley 2, connection, tensioning screw support 6 is equipped with the first through hole passed through for 7 other end of tensioning screw, tensioning screw 7
On in the two sides of through-hole be threadedly engaged tensioning nut 4, cushion 5 is equipped between tensioning nut 4 and tensioning screw support 6,
Cushion 5 is polyurethane cushion 5.
The central axis of tensioning screw 7 and the length direction of waist hole are parallel.
Plain washer is equipped between tensioning nut 4 and cushion 5.
For tensioning screw 7 by the wheel axis connection of tensioning folded plate 3 and tensioning idle pulley 2, tensioning folded plate 3 includes along tensioning idle pulley 2
Symmetrically arranged two L-type plates, one end of L-type plate are equipped with the second through-hole, and the bolt in the wheel shaft is logical also cross second
Hole, the other end of L-type plate are equipped with the third through-hole passed through for tensioning screw 7, are threaded on tensioning screw 7 by two folded plates
