Description

TECHNICAL FIELD

[0001] The utility model relates to a guide structure, in particular to a guide structure of conveying belt. BACKGROUND

[0002] The current conveying mechanism includes a ring-shaped conveying belt, a driving roller, a driven roller, a plurality of guide rollers and a conveying motor, the driving roller, the driven roller and each guide roller are rotatably installed on a rack, the driving roller, the driven roller and each guide roller jointly tension the ring-shaped conveying belt, and the driving roller is in transmission connection with the output shaft of the conveying motor.

[0003] However, the ring-shaped conveying belt is prone to displacement on the roller surface of the driving roller, the driven roller and each guide roller during the conveying process, so that the conveying track deviates from the preset path, resulting in material deviation, dumping or even falling, and affecting the conveying continuity. In addition, the ring-shaped conveying belt has no guide constraint at the turning position, and is prone to twisting and folding due to tension fluctuation and material unbalanced loading, which may cause the conveying belt to be stuck and unable to convey, or even directly tear the belt and cause the equipment to stop. SUMMARY

[0004] The utility model wants to solve the problem of providing a guide structure of conveying belt, which can avoid the deviation of the ring-shaped conveying belt and ensure the conveying continuity.

[0005] In order to solve the above technical problems, the utility model adopts the technical scheme as follows:

[0006] A guide structure of conveying belt, comprising a rack, a ring-shaped conveying belt, a driving roller, a driven roller and a plurality of guide rollers, the driving roller, the driven roller and each guide roller are rotatably installed on the rack, the driving roller, the driven roller and each guide roller jointly tension the ring-shaped conveying belt, characterized in that: at least one guide wheel is further included, the back surface of the ring-shaped conveying belt is provided with a ring-shaped guide convex strip, the roller surface of the driving roller, the driven roller and each guide roller is provided with a first ring-shaped groove matched with the ring-shaped guide convex strip, the groove opening of the first ring-shaped groove faces outward, and the ring-shaped guide convex strip is located in each first ring-shaped groove; the guide wheel is rotatably installed on the rack and arranged between adjacent two guide rollers, a second ring-shaped groove is arranged on the wheel surface of the guide wheel, and one side edge of the ring-shaped conveying belt is located in the second ring-shaped groove.

[0007] Usually, the driving roller is in transmission connection with the output shaft of the conveying motor, and the conveying motor is used to drive the driving roller to rotate, so as to realize the conveying of the ring-shaped conveying belt.

[0008] The annular guide protrusions on the back of the annular conveying belt are always embedded in the first annular grooves on the surfaces of the driving roller, the driven roller and the guide rollers. The first annular grooves on the surfaces of the driving roller, the driven roller and the guide rollers limit the annular guide protrusions in the radial direction. When the annular conveying belt runs, the annular guide protrusions can only move along the conveying direction of the annular conveying belt and cannot deviate from the surfaces of the driving roller, the driven roller and the guide rollers, so that the annular conveying belt is prevented from deviating and the conveying continuity is ensured.

[0009] The second annular grooves on the surfaces of the guide wheels between the adjacent guide rollers accurately clamp the side edges of the annular conveying belt. When the annular conveying belt slightly deviates in the transverse direction due to uneven tension or uneven load of the materials, the side edges of the annular conveying belt are forced to be blocked by the groove walls of the second annular grooves and quickly return to the central position. Meanwhile, the second annular grooves of the guide wheels rigidly limit the side edges of the annular conveying belt at the turning positions of the annular conveying belt, so that the annular conveying belt is prevented from being twisted and folded and the turning process is smooth.

[0010] In the preferred embodiment, the rack is provided with an L-shaped support and a guide seat. The L-shaped support has an integrated transverse support plate and a longitudinal support plate. The transverse support plate is mounted on the rack. The longitudinal support plate is provided with a first slot. The guide seat is provided with a first through hole corresponding to the first slot. A first locking bolt is mounted in the first slot. A first nut is arranged on the rod portion of the first locking bolt. The guide wheel is rotatably mounted on the guide seat. The rod portion of the first locking bolt sequentially passes through the first slot and the first through hole. The head portion of the first locking bolt and the first nut jointly clamp the longitudinal support plate and the guide seat. The guide seat can move up and down along the first slot on the longitudinal support plate to accurately adjust the height of the guide wheel, so that the second annular groove perfectly matches the edges of the belt with different thicknesses and different tensions, and the guiding effect is optimal. The first locking bolt and the first nut clamp the longitudinal support plate and the guide seat, so that the positioning is firm after adjustment and the vibration is not loose.

[0011] In the further preferred embodiment, the transverse support plate is provided with a second slot. The rack is provided with a first screw hole corresponding to the second slot. A second locking bolt is mounted in the first screw hole. The rod portion of the second locking bolt passes through the second slot. The head portion of the second locking bolt and the rack jointly clamp the transverse support plate. The L-shaped support can move horizontally along the second slot on the transverse support plate to adjust the transverse position of the guide wheel, so that the second annular groove accurately clamps the edges of the belt and adapts to the annular conveying belt with different widths, thereby avoiding the guiding failure caused by the misalignment of the guide wheel and the edges of the annular conveying belt. The second locking bolt clamps the transverse support plate and the rack, so that the transverse position of the guide wheel is fixed and deviation is prevented.

[0012] Further preferably, a third strip-shaped hole is further arranged on the transverse support sheet, the third strip-shaped hole is located outside the second strip-shaped hole, a second screw hole corresponding to the third strip-shaped hole is arranged on the rack, a third locking bolt is installed in the second screw hole, the rod part of the third locking bolt passes through the third strip-shaped hole, and the head part of the third locking bolt clamps the transverse support sheet together with the rack. The second strip-shaped hole and the third strip-shaped hole, the second locking bolt and the third locking bolt form a double-hole double-bolt fixing mode, the contact area and the clamping force of the transverse support sheet and the rack are increased, compared with a single-hole single-bolt, the L-shaped support can be prevented from rotating and deviating under the action of belt tension and equipment vibration, and the position of the guide wheel is long-term stable.

[0013] Preferably, the cross section of the annular guide convex strip is trapezoidal or semicircular.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The utility model discloses a main guide locking core track of annular guide convex strip and each first annular groove, and the second annular groove of the guide wheel auxiliary guide completes the steering requirement, can avoid annular conveying belt deviation, and ensures the continuity of conveying.

[0021] For example, Figures 1-4As shown, the guide structure of the conveying belt in the embodiment includes a frame 1, a ring-shaped conveying belt 2, a driving roller 3, a driven roller 6, a plurality of guide rollers 4 and at least one guide wheel 5. The driving roller 3, the driven roller 6 and each guide roller 4 are rotatably installed on the frame 1. The driving roller 3, the driven roller 6 and each guide roller 4 jointly tension the ring-shaped conveying belt 2. The back surface of the ring-shaped conveying belt 2 is provided with a ring-shaped guide protrusion 21. The roller surface of the driving roller 3, the driven roller 6 and each guide roller 4 is provided with a first ring-shaped groove 41 matched with the ring-shaped guide protrusion 21. The notch of the first ring-shaped groove 41 faces outward, and the ring-shaped guide protrusion 21 is located in each first ring-shaped groove 41. The guide wheel 5 is rotatably installed on the frame 1 and arranged between two adjacent guide rollers 4. The wheel surface of the guide wheel 5 is provided with a second ring-shaped groove 51, and one side edge of the ring-shaped conveying belt 2 is located in the second ring-shaped groove 51.

[0022] Generally, the driving roller 3 is in driving connection with the output shaft of a conveying motor. The conveying motor is used to drive the driving roller 3 to rotate, so as to realize the conveying of the ring-shaped conveying belt 2.

[0023] The ring-shaped guide protrusion 21 on the back surface of the ring-shaped conveying belt 2 is always embedded in the first ring-shaped groove 41 of the roller surface of the driving roller 3, the driven roller 6 and each guide roller 4. Each first ring-shaped groove 41 forms radial limiting for the ring-shaped guide protrusion 21. When the ring-shaped conveying belt 2 runs, the ring-shaped guide protrusion 21 can only move along the conveying direction of the ring-shaped conveying belt 2 and cannot be offset on the roller surface of the driving roller 3, the driven roller 6 and each guide roller 4, so as to avoid the deviation of the ring-shaped conveying belt 2 and ensure the continuity of the conveying.

[0024] The second ring-shaped groove 51 on the wheel surface of the guide wheel 5 between two adjacent guide rollers 4 accurately clamps one side edge of the ring-shaped conveying belt 2. When the ring-shaped conveying belt 2 slightly deviates in the transverse direction due to uneven tension and material offloading, the side edge of the ring-shaped conveying belt 2 is forced to be blocked by the groove wall of the second ring-shaped groove 51 and quickly returns to the central position. Meanwhile, the second ring-shaped groove 51 of the guide wheel 5 forms rigid limiting for the side edge of the ring-shaped conveying belt 2 at the turning position of the ring-shaped conveying belt 2, so as to prevent the ring-shaped conveying belt 2 from being twisted and folded and ensure the smoothness of the turning process.

[0025] The rack 1 is provided with an L-shaped support 7 and a guide seat 8. The L-shaped support 7 is integrally provided with a transverse support plate 71 and a longitudinal support plate 72.

The head of the first locking bolt 722 and the first nut 723 jointly clamp the longitudinal support plate 72 and the guide seat 8. The guide seat 8 can move up and down along the first strip-shaped hole 721 on the longitudinal support plate 72, accurately adjust the height of the guide wheel 5, ensure that the second annular groove 51 perfectly matches the edge of the belt with different thicknesses and different tension degrees, and achieve the best guiding effect. The first locking bolt 722 and the first nut 723 clamp the longitudinal support plate 72 and the guide seat 8. After adjustment, the position is firm and does not loosen due to vibration.

[0026] The transverse support plate 71 is provided with a second strip-shaped hole 711. The rack 1 is provided with a first screw hole 11 corresponding to the second strip-shaped hole 711. A second locking bolt 12 is arranged in the first screw hole 11. The rod of the second locking bolt 12 penetrates the second strip-shaped hole 711. The head of the second locking bolt 12 and the rack 1 jointly clamp the transverse support plate 71. The L-shaped support 7 can move horizontally along the second strip-shaped hole 711 on the transverse support plate 71, adjust the transverse position of the guide wheel 5, ensure that the second annular groove 51 accurately clamps the edge of the belt, adapt to annular conveying belts 2 with different widths, and avoid guiding failure caused by misplacement of the guide wheel 5 and the edge of the annular conveying belt 2. The second locking bolt 12 clamps the transverse support plate 71 and the rack 1. The transverse position of the guide wheel 5 is fixed, and deviation is prevented.

The rod of the third locking bolt 14 penetrates the third strip-shaped hole 712. The head of the third locking bolt 14 and the rack 1 jointly clamp the transverse support plate 71. The second strip-shaped hole 711 and the third strip-shaped hole 712, the second locking bolt 12 and the third locking bolt 14 form a double-hole double-bolt fixing mode, which increases the contact area and clamping force of the transverse support plate 71 and the rack 1. Compared with a single-hole single-bolt, the L-shaped support 7 can be prevented from rotating and deviating under the action of belt tension and equipment vibration, so that the position of the guide wheel 5 is stable for a long time.

[0028] The cross section of the annular guide convex strip 21 is trapezoidal.
