Description

Pattern conveyor belt

Technical field:

The utility model relates to the band that a kind of rubber or plastics are made, particularly a kind of band with surperficial outshot.

Background technology:

Existing pattern conveyor belt, the load-transfer device that promptly has the outshot decorative pattern on the band body surface, its typical structure has following several: Chevy Trucks, waveform decorative pattern and sparrow pecked etc., be applicable to respectively and carry different materials, be applicable to the bulk cargo transportation as Chevy Trucks and waveform decorative pattern, sparrow pecked is applicable to carries the monolithic devices material.Existing pattern conveyor belt is to tilt at full bandwidth to arrange the decorative pattern slanted bar, when being applied to large conveying quantity, long distance, the transportation of high spud angle bulk cargo, has following defective:

1, the area of contact of decorative pattern and cylinder is little, so the specific pressure that decorative pattern bears is big, even the value of overstepping the extreme limit, thereby the service life of decorative pattern is very short.

2,, be only applicable to single drum driven mode (as Fig. 1) and do the little freight volume conveying of short range owing to the restriction of specific pressure;

3, bonding with the cold bonding technology between pattern rib and the load-transfer device body, bond strength is low, and when decorative pattern process cylinder, pattern rib easily peels off;

4, when adopting four carrying roller deep trouth angle high spud angles to carry, its groove forming character is relatively poor, and when no-load run, load-transfer device easily produces the ribbon phenomenon;

5, owing to the existence of decorative pattern face, load-transfer device lifts fluctuation of service on the roller in backhaul, so backhaul lifts the carrying roller (as the comb shape carrying roller) that roller need adopt special shape, the increase equipment cost.

Summary of the invention:

The technical problems to be solved in the utility model provides a kind of improved pattern conveyor belt, and it can prolong the service life of decorative pattern, improves groove forming character, is fit to long distance, large conveying quantity, high spud angle conveying, and operates steadily.

The technical scheme in the invention for solving the above technical problem is: be laid with the decorative pattern slanted bar at the middle part of load-transfer device body, dual-side at the load-transfer device body is laid with riglet, between each decorative pattern slanted bar medial extremity, be provided with spacing between each decorative pattern slanted bar external side end and two riglets.

Riglet thickness is greater than decorative pattern slanted bar thickness.

Its two riglet of the utility model mat increases the area of contact of band and cylinder, reduce decorative pattern slanted bar specific pressure, increase the service life of decorative pattern, and can adopt twin-roll to drive, thereby be fit to long distance, large conveying quantity, high spud angle conveying, spacing setting between its decorative pattern slanted bar and the riglet, increased the groove forming character of pattern conveyor belt load-transfer device when four carrying roller deep trouth angle high spud angles are carried, thickness difference setting between its decorative pattern slanted bar and the riglet, make load-transfer device when homeward journey, the contact of decorative pattern slanted bar discord carrying roller, thus load-transfer device is operated steadily.

Description of drawings:

Fig. 2 is a load-transfer device twin-roll type of drive scheme drawing.

Fig. 3 is a load-transfer device decorative pattern slanted bar symmetric offset spread scheme drawing.

Fig. 4 is the alternate scheme drawing that is staggered of load-transfer device decorative pattern slanted bar.

Fig. 5 is the cross-sectional scheme drawing of looking of load-transfer device.

The specific embodiment:

With reference to Fig. 1, single drum driven mode of diagram load-transfer device includes driving drum 1, changed course cylinder 2 and pattern conveyor belt 3, and this kind type of drive is suitable for the transportation of short range, little freight volume high spud angle.

With reference to Fig. 2, the twin-roll type of drive of diagram load-transfer device includes pattern conveyor belt 3, driving drum (one) 4 driving drum (two) 5 and changed course cylinder 6, and this kind type of drive is suitable for long distance, large conveying quantity, high spud angle transportation.

With reference to Fig. 3, Fig. 4, Fig. 5, pattern conveyor belt 3 includes load-transfer device body 9, decorative pattern slanted bar 8 and riglet 7, and whole sulfuration, makes decorative pattern slanted bar 8 incrust when the pile warp cylinder, thereby improves the service life of decorative pattern slanted bar 8;

Decorative pattern slanted bar 8 is the middle parts that are laid in load-transfer device body 9, and evenly distributed continuously along the length direction of load-transfer device 3, its arrangement mode is symmetry, and the equal symmetry of the medial extremity of each decorative pattern slanted bar 8 is positioned at the line of centers of load-transfer device body 9, as shown in Figure 3, form the V-type pattern structure; The another kind of mode of arranging is alternate and is staggered, and the medial extremity of each decorative pattern slanted bar 8 is alternate to be staggered in the line of centers both sides of load-transfer device body 9, as shown in Figure 4, forms chevron shaped pattern structure; No matter that a kind of pattern structure, load-transfer device body 9 line of centerss all have two row decorative pattern slanted bars 8 relatively, maintain a spacing b (shown in Fig. 3,4) between the medial extremity of each decorative pattern slanted bar 8 of both sides, the width B value of this spacing b value and load-transfer device body 9 is determined by following equation:

b＝(1/30～1/10)B；

Spacing b can increase the groove forming character of load-transfer device 3 when four carrying rollers, deep trouth angle, high spud angle conveying; Each decorative pattern slanted bar 8 all is certain angle of inclination and is respectively in load-transfer device body 9 line of centers both sides, can be according to the difference of convey materials, the angle of inclination that select to adapt to, promptly angle α (shown in Fig. 3, the 4) value between each decorative pattern slanted bar 8 and load-transfer device body 9 line of centerss is 5 ° and does not wait to 65 °;

Riglet 7 is the dual-sides that are laid in load-transfer device body 9 respectively, and arrange along the length direction Symmetrical Continuous of load-transfer device 3, shown in Fig. 3,4, the riglet of setting up 7 can obviously reduce the specific pressure of decorative pattern slanted bar 8, thereby can make load-transfer device 3 satisfy large conveying quantity, long distance, the conveying of high spud angle bulk cargo, the width a of each riglet and the width B value of load-transfer device body 9 can be determined by following equation:

a＝(1/10～1/3)B；

In order to increase the groove forming character of load-transfer device 3 when four carrying rollers, deep trouth angle, high spud angle are carried, maintain a spacing c (shown in Fig. 3,4) between the external side end of the inner side edge of two riglets 7 and two each decorative pattern slanted bar 8 of row, the width B value of this spacing c value and load-transfer device body 9 is determined by following equation:

c＝(1/30～1/10)B；

With reference to Fig. 5, riglet 2 is different with the height of decorative pattern slanted bar 8 projection on the base plane of load-transfer device body 9, be the thickness of the thickness of riglet 7 greater than pattern rib 8, this structure makes load-transfer device 3 when homeward journey, the 8 discord carrying roller contacts of decorative pattern slanted bar, use maintenance load-transfer device 3 and operate steadily, the discrepancy in elevation h (as shown in Figure 5) between riglet 7 and the decorative pattern slanted bar 8 can determine by following equation:

H=0+ (plus tolerance)～5mm;

The utility model has reduced the specific pressure of decorative pattern slanted bar 8, increases the service life of decorative pattern slanted bar 8, and can enlarge Applicable scope, can improve groove forming character simultaneously, improves the drive ability of load-transfer device 3.
