Utility model works principle and main structure：
, by a sprocket wheel with pretightning force as chain swelling wheel, pretightning force is by installed in swelling wheel back sleeve for the device
Interior compression spring is produced, the size that tightening force can be changed by the front and back position of regulating sleeve guide holder, and by pull bar
The upper final fixed guide seat of adjusting nut is put, when chain is when relaxing or shaking, can be increased by adjusting adjusting screw rod position
Swelling stroke, so that increasing spring pressure solves the problems, such as that chain conveying is unstable.
The swelling device is a part for whole chain circulation, is produced with fatigue wear when being conducted oneself with dignity due to chain in course of conveying
During raw relaxation, the device is installed at chain lax place, chain enters more than chain along the fixed chain wheels on chain pulley seat from left side
Amount part, chain run trace, can be by a chain expansion mechanism in chain walking process in " Ω " shape, the swelling machine
Swelling sprocket wheel in structure tenses lax chain, and pulling force is from the pressure bullet installed in swelling sprocket wheel back sleeve and socket cover
Spring, and swelling sprocket wheel is passed to by piston shape pull bar and the drawhead installed, form is similar to cylinder ante-chamber supply extruding cylinder
The principle of bar piston, simply the energy source of this set expansion mechanism is spring mechanical formula rather than Pneumatic-control type, and this form ensures swollen
Clamp force does not disappear persistently, reliable and stable, will not there is the hypodynamic phenomenon of swelling because of the change of chain, and sleeve is pacified by axle sleeve
On guide holder, sleeve can in right amount adjust angle, eliminate chain conveying jitter phenomenon, and the gathering sill on the downside of guide holder can edge
Support base floor level slides, and the adjusting screw rod of guide holder back is put by adjusting nut fixed guide seat, so ensures length
Time operates the holding of rear chain tension force, and is easy to the later stage to unclamp the dismounting chain maintenance of chain swelling surplus and change, right
Plant maintenance has positive role, fullys meet expected design effect after tested in practice.
The device is also replaced by belt and belt wheel swelling, applies in V belt translation conveying equipment, effectively solve chain and
Production precision and inefficiency problem that belt slack is caused.
The device is simple, easy-to-use, durable, adjustable, easily change, and improves the stability of conveying, reduces noise, overcomes it
The shortcomings of its form of device is complicated, volume is big.
It is above-mentioned with reference to embodiment to being applied to the detailed description that carries out of swelling device of chain conveying, be it is illustrative without
It is limited；Therefore changing and modifications in the case where the utility model general plotting is not departed from, should belong to protection of the present utility model
Within the scope of.
