Abstract

The utility model relates to automatic position limiting deviation preventing apparatus for overcoming the deviation of the rubber belt of rubber belt conveyers. Two position limiting depending wheels which can be freely rotated are arranged on both sides of the rubber belt, and the two depending wheels are connected with both ends of a supporting roller set which is supported on the lower part of the rubber belt and is freely swung. When the rubber belt is deviated to one side, the rope is tightened after the depending wheel rubbing the side is rotated, the supporting roller set is deflected to the other side so that side friction is produced to the rubber belt, and thus the rubber belt is returned to the original position.

Description

Automatic position-limiting & anti-deviating apparatus for rubber belt of conveyer

The utility model belongs to a kind of automatic spacing anti-deflection device that travelling apron prevents the transferring adhesive tape sideslip that is used for.

Travelling apron is to use very wide material transfer equipment in the production industry, in actual applications, because the aging distortion of adhesive tape, reasons such as the unbalance loading of material on adhesive tape and some mechanical breakdowns, to offset to one side on the frame be rubber belt from deviating to the adhesive tape that all can cause operation carrying, rubber belt from deviating can make the material of conveying scatter, adhesive tape is scratched, and influence is produced and caused economic loss, and existing deviation correcting device is because shortcoming structurally, make its tuningout amplitude little, dynamics is little, and it is big that adhesive tape is permitted the beat degree, and mechanism is dumb, often stuck, the rubber belt from deviating problem can not thoroughly be solved.

The purpose of this utility model is the shortcoming at existing deviation correcting device, studies a kind of going slick, the tuningout great efforts, and the little travelling apron anti-deflection device of beat degree is accurately permitted in the adhesive tape location.

Accompanying drawing is a structural representation of the present utility model.

Substance of the present utility model is at two rollers that can freely rotate of the both sides of adhesive tape installing, adorning a picking-up adhesive tape below adhesive tape also can be the carrying roller group that axle freely swings with the mid point, be connected by the end of the rope on roller with the carrying roller group, the friction roller makes it to rotate when rubber belt from deviating, tightening up a rope makes the carrying roller group to reversing sense deflection, forces adhesive tape to be returned to the home position.The specific embodiments of this design is as follows.

Install respectively in adhesive tape both sides 1. right roller 3. with left roller 4., make two rollers near adhesive tape edge 1., but do not contact, adhesive tape 1. below one of installing can hold adhesive tape 1. and can be with the centre swing carrying roller group that freely swings of axle 2., with rope 5. be wrapped in roller 3. with 4. several Zhou Houzai of roller with swing carrying roller group two ends 2. and be connected.According to actual conditions, can to roller 3., 4. roller install reduction gear apparatus additional, rope is 5. on deboost axle, to increase pulling force and to reduce carrying roller group swing speed 2..For the sealing-tape machine of folk prescription to operation, available two ropes connect the roller and the swing carrying roller group end 2. of respective side respectively.

When 1. sideslip takes place in adhesive tape to the right that advance, 3. the right roller that rubs makes it to rotate and tightly wraps rope 5., 2. pulling swing carrying roller group deflects left, 1. adhesive tape is produced a side-friction force left, make adhesive tape 1. be returned to original position left, as a same reason, when adhesive tape 1. to the left during sideslip, corrected return too to the right, when 1. adhesive tape moves backward, also can be corrected sideslip.

The utility model has the advantages that highly sensitively, correct the sideslip great efforts, adhesive tape is limited in the middle of two rollers on the very accurate position, makes the rectilinearity of adhesive tape operation be able to reliable assurance, has fundamentally prevented the sideslip of adhesive tape,

Claims

1, a kind of travelling apron automatic spacing anti-deflection device that constitutes by roller and swing carrying roller group, it is characterized in that said roller for be contained in respectively adhesive tape 1. both sides the right roller that can freely rotate 3. with left roller 4., two rollers are near adhesive tape edge 1., but do not contact, said swing carrying roller group be contained in transferring adhesive tape hold below 1. adhesive tape 1. and can be with the centre swing carrying roller group that freely swings of axle 2., be wrapped in roller by one and 3. 5. be connected with swing carrying roller group two ends 2. with the rope that 4. roller is gone up.

2,, it is characterized in that said roller can install reduction gear apparatus additional, to increase rope pulling force 5. and to reduce carrying roller group swing speed 2. according to the said anti-deflection device of claim 1.
