Description

Replace two-sided upset travelling apron voluntarily

Technical field

The utility model relates to a kind of transportation device, particularly travelling apron.

Background technology

Domestic and international existing travelling apron is a kind of material transfer equipment of being made up of adhesive tape for no reason, cylinder, carrying roller, driving and brake equipment, tightening device and the loading and unloading (chute) etc. of closure, as shown in Figure 1.Adhesive tape has the branch of carrying surface and non-bearing face.Advantages such as this load transfer device is simple because of having, high efficient and reliable, traffic cost are low, the big and easy maintenance of upwards of movement and being widely used.

The working process of this load transfer device is as follows: the material acceptance glide chute of sealing-tape machine afterbody is accepted material; Adhesive tape in the running (carrying surface) is accepted material and by moving of adhesive tape material is transported to forward in the chute of sealing-tape machine head under chute; Deliver to material on next sealing-tape machine or on the stocker, by the material acceptance glide chute of head until delivering to the destination.Inevitable because of the wearing and tearing of adhesive tape carrying surface, an adhesive tape stops service life at this point when may wear to belt carcass, just must change new adhesive tape; Perhaps using the adhesive tape carrying surface when belt carcass still has certain thickness, adhesive tape is being cut off to stand up again reuse former non-bearing face after the row splicing.The former must cause the waste of adhesive tape non-bearing cover glue resource, and latter's adhesive tape stands up utilization and must shut down and carry out, and time-consuming, take thing, expense is artificial.

Summary of the invention

The purpose of this utility model is to design a kind of simple in structure, the conveyer adhesive tape that in operational process, can overturn automatically, realize automatically the upset of adhesive tape carrying surface being the non-bearing face after adhesive tape moves a week, the upset of adhesive tape non-bearing face is carrying surface, the use that constantly moves in circles, what make that adhesive tape prolongs service life replaces two-sided upset travelling apron voluntarily.

For achieving the above object, the utility model comprises adhesive tape, supporting device, driver train, counterweight; Described supporting device comprises frame, a plurality of cylinder and a plurality of upper and lower carrying roller and respective holder; Described cylinder and upper and lower carrying roller and respective holder are fixedly connected on the frame, and wherein a cylinder connects counterweight; Driver train links with the cylinder that is arranged at the frame end; Adhesive tape is sheathed on cylinder, carrying roller becomes closed adhesive tape for no reason; Also comprise the adhesive tape switching mechanism, described adhesive tape switching mechanism comprises double-type nip rolls group of at least three groups and corresponding fixed frame, described nip rolls group successively in the shape of a spiral shape arrange and be fixed on the fixed frame, this fixed frame is fixed on the frame, the adhesive tape switching mechanism is installed in the zero load place of adhesive tape, promptly in the return of the adhesive tape way; Described adhesive tape is arranged in the nip rolls group of shape arrangement in the shape of a spiral, to realize the adhesive tape upset.In addition, adhesive tape adopts antarafacial to glued joint at closing end, and promptly the closed two ends pros and cons of adhesive tape (former carrying surface and non-bearing face) glued joint.So far, transferring adhesive tape has possessed automatic turn over function, after adhesive tape is finished a circular flow, promptly by once being the adhesive tape switching mechanism of 180 degree spiral fashion nip rolls groups successively, also just realizes the automatic 180 degree upsets in adhesive tape safety and steady ground.

Advantage of the present utility model is: by the zero load place at adhesive tape the adhesive tape switching mechanism is set, adhesive tape realizes that through the nip rolls group adhesive tape turns over turnback, constantly moves in circles, and adhesive tape is prolonged service life.

Concrete real trip mode

As shown in Figure 2, the utility model comprises adhesive tape 5, supporting device, driver train, counterweight 13; Described supporting device comprises frame 1, a plurality of cylinder 2,6,7,10 and respective holder and a plurality of upper and lower carrying roller 3,4; Described cylinder 2,6,7,10 and respective holder 11 and upper and lower carrying roller 3,4 are fixed on the frame 1, and wherein a cylinder 12 connects counterweight 13; Driver train links with the cylinder 2 that is arranged at the frame end; Adhesive tape 5 is sheathed on cylinder 2,6,7,10 and carrying roller 3,4 one-tenth closed adhesive tapes for no reason.

Adhesive tape switching mechanism 15 comprises five groups of double-type nip rolls groups 151,153,154,155,156 and corresponding fixed frame 152, this nip rolls group successively in the shape of a spiral shape arrange and be fixed on the fixed frame, wherein the nip rolls group 151,156 is horizontal nip rolls, nip rolls group 153 is turned over nip rolls in being, nip rolls group 154 is vertical nip rolls, nip rolls group 155 is the nip rolls that turns up, fixed frame 152 is fixed on the frame 1, this adhesive tape switching mechanism 15 is installed in the zero load place of adhesive tape 5, adhesive tape 5 is arranged in the nip rolls group of shape arrangement in the shape of a spiral, by turning over the nip rolls group 153 of nip rolls in the conduct, the nip rolls group 154 of vertical nip rolls and the nip rolls group 155 of the nip rolls that turns up, realize that adhesive tape 5 turns over turnback, as shown in Figure 3.

Can very transform all travelling aprons economically, impacted by material and operational throughput greatly and the travelling apron of adhesive tape quick abrasion.This invention device is economic, practical, simple in structure, safe, reliable, and is also simple to rebuilding old equipment, can be extensively should be in metallurgy, mining, coal, thermal electric generation, harbour etc. uses the industry of sealing-tape machine convey materials.
