Abstract
The invention belongs to an extension roller for a strap wrapping machine solving the defects of the prior art like complex structure, expensive cost, large energy consumption and multifarious manufacture, etc. The technical measures of the invention are that the extension roller essentially consists of a mandrel (1), rolling bearings (2) at two ends of the mandrel (1), a drum (3) and an adjustor (8). The drum (3) consists of a middle drum (4) and two side drums (5) symmetrically arranged at two sides of the middle drum (4). The middle drum (4) and the mandrel (1) are arranged in wringing fit. The side drums (5) and the mandrel (1) are arranged in loose fit. The outer diameter of the middle drum (4) is larger than the outer diameters of the side drums (5). The mandrel (1) at the external side of the side drums (5) is provided with a limiting check ring (6). The middle drum (4) is provided with an underlayer (9). The invention realizes automatic deviation rectifying within a small range during the running process of the strap and has the advantages of simple structure, convenient maintenance and great reduction on the off tracking times of the strap.
Description
Technical field
The present invention relates to the belt transportation driving device, belong to the idler roller of strap rolling-assisting device exactly.
Background technology
At present, idler roller is to copy Japanese rolling-assisting device principle to come design-calculated mostly on the strap rolling-assisting device, all idler rollers all do not have the automatic deviation correction function in its roller system, have only the tolerance clearance of manhole on eccentric bushing that two adjustable idler rollers rely on both sides and the fixed bearing to regulate, the axis angle of the adjustable idler roller of promptly artificial adjusting is improved the sideslip of belt.Such control method can not well solve practical problems, and adjust finish after, can't make corresponding automatic deviation correction according to the belt deviation phenomenon that actual conditions take place at all.Because in process of production, the plate shape fluctuation of steel plate, roller and the wearing and tearing inequality, the accumulated error that a lot of factors such as working accuracy, setting accuracy, reel precision and micro-deformation of objective problem such as the tension force of belt own, became uneven and each assembly of frame cause very easily makes belt produce deviation phenomenon.Therefore in the operational process, belt often is in the abnormal running state, and producers often need the absent-mindedness belt tension, belt is drawn be put into the idler roller midway location, and then recovers to use, and constantly repeats this loaded down with trivial details, dangerous work.Simultaneously, the sideslip of belt has also been accelerated the degree of wear of belt, and very easily be torn, break, initiating failure, thus influence ordinary production.At present, people are the sideslip problem that prevents that sheet metal strip, non-metal band are in operation, and have taked many technical measures, but carry out automatic deviation correction control by the array mode that adopts light, electricity, liquid, control quaternity mostly.Its complex structure involves great expense, is inconvenient to safeguard, and a large amount of consumes energy.Other has the mode of some corrections, though simple, certain effect is arranged, can not solve the belt deviation problem at all.As the Chinese patent notification number is the patent documentation of CN2206268Y " anti-beat belt roller ", it discloses, and a kind of surface at roller axially equidistantly distributes and the anti-beat technology of the boss of circumferencial direction osed top one ring ring surface slyness, though it is simple in structure, and adopt the part theory of machines to prevent sideslip.But its weak point:
(1): this design-calculated roll surface must make the belt of operation thereon jitter phenomenon occur, and the speed of belt operation is high more, and the shake that is taken place is big more, so the loads on the belt must reach certain weight and just can for loose unpacked material.Otherwise, still want sideslip.
(2): whole belt still is same horizontal surface contact with contacting of roll surface, also is very limited so prevent the effect of the horizontal sideslip of belt.
(3): complex manufacturing technology, productive costs height.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of do not need independent deviation correction mechanism, simple in structure, adopt theory of machines to the sideslip of belt among a small circle, carry out the adjustable automatically deviation rectifying leather belt roller of automatic deviation correction.
Realize the technical measures of above-mentioned purpose:
A kind of adjustable automatically deviation rectifying leather belt roller, mainly form by mandrel, roller, regulating control and the antifriction-bearing box one that is installed on the described regulating control at mandrel two ends, it is: the limit portion roller on roller both sides was formed in the middle of roller was installed in by middle roller, symmetry, middle roller and mandrel flush fit are installed, and install for easy fit between limit portion roller and the mandrel; The external diameter of middle roller is greater than the external diameter of limit portion roller; On the mandrel in the limit portion roller outside, spacing back-up ring is installed; On the middle roller lining is housed; On the mandrel at the two ends of each limit portion roller, antifriction-bearing box two is housed.
It is: the length of middle roller is 1~3 times of two limit portion roller sums.
It is: between middle roller and the limit portion roller 0.8~3 mm clearance is arranged.
It is: the external diameter of middle roller is bigger 2~10 millimeters than the external diameter of limit portion roller.
It is: the surface of limit portion roller is smooth.
It is: the driving surface of spacing back-up ring is smooth.
Realize the mechanism of automatic deviation correction:
The present invention utilizes belt in a circumferential direction always to the principle of the big direction sideslip of friction force that tension force produced, and belt is carried out automatic deviation correction.Because leather belt roller of the present invention is three-section type, promptly be installed on the mandrel and along with mandrel rotates together, gapped between limit portion roller and the mandrel, limit portion roller can freely rotate with respect to mandrel by middle roller.That is to say that the middle part roller can the relative rotation of making different rotating speeds freely around same axis with limit portion roller.Because its constructional feature, cause belt different with the limit portion suffered friction force of roller at the middle part roller.In order to strengthen the friction force between belt and the middle part roller, so the external diameter of roller (4) is 1.5~3 times of two limit portion rollers (5) sum, middle roller (4) technical measures for polyamine fat or chlorine tincture rubber than the external diameter length big 2~10 millimeters, middle roller (4) of limit portion roller (5) in the middle of taking.
When sideslip appears in belt, because the effect of spacing back-up ring (6) makes belt stop sideslip.Simultaneously, again because the surface of limit portion roller (5) is smooth, and the friction force of middle roller (4) is big, and the principle that moves to the big direction of friction force according to belt is so realized automatic deviation correction.
The present invention compared with prior art, the length of contact of belt and middle roller remains on 50~80%, realized automatic deviation correction interior among a small circle in the belt operation process, and it is simple in structure, easy to maintenance, prolonged the service life of belt and belt transportation mechanism, improve operating rate, thereby cause the reduction of productive costs, association area is used in the same way.
