[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] The following describes a conveyor belt flipping and multiplexing method based on a belt conveyor according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0036] like Figures 1 to 6 As shown, the conveyor belt flipping and multiplexing method based on the belt conveyor of the embodiment of the present invention comprises the following steps:

[0037] The conveyor belt 2 is loosened, and then the conveyor belt 2 is cut so that the conveyor belt 2 has a first end 21 and a second end 22. Specifically, a belt clamp is set on the conveyor belt 2, the conveyor belt 2 is lifted to a set height, and then the conveyor belt 2 is cut along the width direction of the conveyor belt 2, one end of the conveyor belt 2 at the cut forms the first end 21, and the other end of the cut forms the second end 22.

[0038] The conveyor belt 2 is driven to rotate so that there is a set distance between the first end 21 and the second end 22. Specifically, the first end 21 is pulled to move away from the second end 22, so that the distance between the first end 21 and the second end 22 increases to the set distance. Thus, it is convenient to set a plurality of turning rollers 3 between the first end 21 and the second end 22.

[0039] The rubber layer of the conveyor belt 2 at the first end 21 and the second end 22 is peeled off to expose the steel wire rope, and a plurality of turning rollers 3 are installed at set intervals. Specifically, the conveyor belt 2 is a steel wire rope core conveyor belt 2, and the core rubber layer and the covering rubber layer of the conveyor belt 2 at the first end 21 and the second end 22 are peeled off to expose the steel wire rope at the first end 21 and the second end 22 by a set length.

[0040] Multiple turning rollers 3 are arranged at intervals along the length direction of the conveyor belt 2, and the angle between the axial direction of the multiple turning rollers 3 and the width direction of the belt conveyor 1 gradually increases along the length direction of the belt conveyor 1 to drive the conveyor belt 2 to twist along the length direction of the conveyor belt 2.

[0041] The steel wire rope is turned over and passed through the plurality of turning rollers 3. Specifically, the steel wire rope at the first end 21 is extended through the plurality of turning rollers 3 along the extension direction of the plurality of turning rollers 3, and the steel wire rope at the first end 21 passes through the plurality of turning rollers 3, so that the end of the steel wire rope at the first end 21 is close to the second end 22.

[0042] The steel wire rope at the first end 21 and the steel wire rope at the second end 22 are connected and fixed. Specifically, the steel wire rope at the first end 21 and the steel wire rope at the second end 22 are detachably connected, thereby connecting the first end 21 and the second end 22 through the steel wire rope at the first end 21 and the steel wire rope at the second end 22, so that the cut conveyor belt 2 is closed to form a ring, which facilitates the conveyor belt 2 to rotate under the drive of the conveyor.

[0043] The conveyor belt 2 is driven to rotate one circle to turn the conveyor belt 2 over completely. Specifically, the belt conveyor 1 drives the conveyor belt 2 connected by the steel wire rope of the first section and the steel wire rope of the second end 22 along the Figure 2 The first end 21 rotates one circle in the direction a shown in the figure, and passes through a plurality of turning rollers 3 under the traction of the steel wire rope of the first end 21, so that the conveyor belt 2 downstream of the first end 21 passes through a plurality of turning rollers 3, and the conveyor belt 2 turns half a circle along the circumference of the conveyor belt 2 when passing through the plurality of turning rollers 3.

[0044] When the conveyor belt 2 rotates one circle until the plurality of turning rollers 3 are located between the first end 21 and the second end 22, the belt conveyor 1 stops driving the conveyor belt 2 to rotate. Thus, the conveyor belt 2 is completely turned over half a circle by the turning mechanism, the bearing surface of the conveyor belt 2 in contact with the material is turned over to the side of the conveyor belt 2 facing away from the material, and the side of the conveyor belt 2 in contact with the belt conveyor 1 is turned over to the side in contact with the material.

[0045] Remove multiple turning rollers 3, and then use a vulcanization process to connect the first end 21 and the second end 22 of the conveyor belt 2. Specifically, remove multiple turning rollers 3, disconnect the steel wire ropes at the first end 21 and the steel wire ropes at the second end 22, so that the steel wire ropes at the first end 21 and the steel wire ropes at the second end 22 are arranged in a staggered manner, and then core rubber is coated on the outer peripheral side of the steel wire ropes at the first end 21 and the steel wire ropes at the second end 22, and after the core rubber is cured to form a core rubber layer, a covering rubber is coated on the outer peripheral side of the core rubber, and after the cured rubber layer is cured to form a covering rubber layer.

[0046] The conveyor belt flipping and reuse method based on a belt conveyor in an embodiment of the present invention is achieved by arranging a plurality of detachable flip rollers 3 on the belt conveyor 1, and then driving the conveyor belt 2 to pass through the plurality of flip rollers 3. When the conveyor belt 2 passes through the flip rollers 3, the conveyor belt 2 flips half a circle along the extension direction of the flip rollers 3, so that the bearing surface of the conveyor belt 2 in contact with the material is flipped to the side of the conveyor belt 2 away from the material, and the side of the conveyor belt 2 in contact with the belt conveyor 1 is flipped to the side in contact with the material. The conveyor belt flipping and reuse method based on a belt conveyor in an embodiment of the present invention does not require the conveyor belt 2 to be completely disassembled from the belt conveyor 1, thus saving the time and space occupied by the flipping and reused conveyor belt 2, and thus has the advantage of high flipping efficiency.

[0047] In some embodiments, the plurality of turning rollers 3 are arranged in a double spiral. Figure 3 and Figure 4 As shown, the planes where the rotating axes of the multiple turning rollers 3 are located are arranged at intervals and parallel to each other along the length direction of the conveyor belt 2, and the angle between the axial direction of the multiple turning rollers 3 and the width direction of the belt conveyor 1 gradually increases along the length direction of the belt conveyor 1.

[0048] The turning roller 3 has a first end 21 and a second end 22. The line connecting the first ends 21 of the plurality of turning rollers 3 forms a first spiral line, and the line connecting the second ends 22 of the plurality of turning rollers 3 forms a second spiral line. The first spiral line and the second spiral line are cylindrical spiral lines. The central axis of the first spiral line and the central axis of the second spiral line are parallel to the length direction of the belt conveyor 1. The first spiral line and the second spiral line have the same rotation direction, the same lead, the same axes, and the phase difference along the length direction is a semicircle.

[0049] Thus, when the conveyor belt 2 passes through the plurality of reversing rollers 3 , it is twisted along the extending direction of the reversing rollers 3 , and when the conveyor belt 2 is twisted between the plurality of reversing rollers 3 , it takes a double helix shape.

[0050] In some embodiments, the extension directions of the plurality of turning rollers 3 and the angles α between the turning rollers 3 and the conveyor belt 2 within the set interval are arranged in an arithmetic progression.

[0051] Specifically, the angle α of the turning roller 3 is the angle between the central axis of the turning roller 3 and the width direction of the belt conveyor 1, and the angles between the central axes of two adjacent turning rollers 3 are the same. Therefore, when the conveyor belt 2 passes through multiple turning rollers 3 and twists, the twist angle of the conveyor belt 2 is uniform, so that the conveyor belt 2 is uniformly stressed when it turns, avoiding damage to the conveyor belt 2 due to uneven stress.

[0052] In some embodiments, the multiple turning rollers 3 include a first roller, a second roller 32, a third roller 33, a fourth roller 34 and a fifth roller 35, the angle α of the first roller 31 is 30 degrees, the angle α of the second roller 32 is 60 degrees, the angle α of the third roller 33 is 90 degrees, the angle α of the fourth roller 34 is 120 degrees, and the angle α of the fifth roller 35 is 150 degrees.

[0053] Specifically, Figure 4 As shown, there are five turning rollers 3, and the angle α of the turning rollers 3 is the angle between the central axis of the turning rollers 3 and the width direction of the belt conveyor 1. The angle α of the first roller 31 is 1 is 30 degrees, the angle α of the second roller 32 2 is 60 degrees, the angle α of the third roller 33 3 is 90 degrees, the angle α of the fourth roller 34 4 is 120 degrees, the angle α of the fifth roller 35 5 The axial included angle of two adjacent turning rollers 3 is the same at 150 degrees.

[0054] Therefore, when the conveyor belt 2 passes through a plurality of turning rollers 3 and is twisted, the twisting angle of the conveyor belt 2 is uniform, so that the conveyor belt 2 is subjected to uniform force when it is turned over, thereby preventing the conveyor belt 2 from being damaged due to uneven force.

[0055] In some embodiments, the distance between two adjacent turning rollers 3 along the length direction of the belt conveyor 1 is 2 meters. Therefore, the distance between two adjacent turning rollers 3 is large, which reduces the degree of torsion when the conveyor belt 2 is turned over, preventing the conveyor belt 2 from twisting excessively and thus damaging the conveyor belt 2.

[0056] In some embodiments, the steel wire rope at the first end 21 and the steel wire rope at the second end 22 are detachably connected via a connector 4. Specifically, Figure 5 and Figure 6As shown, the connecting member 4 is a rope clamp, and the steel wire rope at the first end 21 and the steel wire rope at the second end 22 form multiple steel wire rope strands. The connecting member 4 connects the steel wire rope strands at the first end 21 and the steel wire rope strands at the second end 22, thereby connecting the steel wire rope at the first end 21 and the steel wire rope strands at the second end 22.

[0057] Therefore, the steel wire rope strands at the first end 21 and the steel wire rope strands at the second end 22 are connected by a rope clamp, which on the one hand improves the strength of the connection between the steel wire rope at the first end 21 and the steel wire rope at the second end 22, and on the other hand reduces the workload of connecting the steel wire rope at the first end 21 and the steel wire rope at the second end 22, thereby improving the work efficiency of connecting the steel wire rope at the first end 21 and the steel wire rope at the second end 22.

[0058] In some embodiments, before vulcanizing the conveyor belt 2, the following steps are included: loosening the conveyor belt 2 and disassembling the connector 4. Specifically, before vulcanizing the conveyor belt 2, multiple turning rollers 3 are removed, and the steel wire ropes at the first end 21 and the steel wire ropes at the second end 22 are disconnected, so that the steel wire ropes at the first end 21 and the steel wire ropes at the second end 22 are arranged in a staggered manner, and then core rubber is coated on the outer peripheral side of the steel wire ropes at the first end 21 and the steel wire ropes at the second end 22, and after the core rubber is cured to form a core rubber layer, a covering rubber is coated on the outer peripheral side of the core rubber, and after the cured rubber layer is cured, a covering rubber layer is formed.

[0059] Thus, the conveyor belt 2 is loosened and the connector 4 is disassembled to adjust the spacing between the first end 21 and the second end 22 so that the steel wire ropes at the first end 21 and the steel wire ropes at the second end 22 are arranged alternately, and then the first end 21 and the second end 22 are sent to the vulcanizer for vulcanization.

[0060] In some embodiments, when connecting and fixing the steel wire rope at the first end 21 and the steel wire rope at the second end 22, the following steps are included: the steel wire rope at the first end 21 has a first rope strand 211 and a second rope strand 212, the steel wire rope at the second end 22 has a third rope strand 221 and a fourth rope strand 222, the connecting piece 4 includes a first piece 41 and a second piece 42, the first piece 41 detachably connects the first rope strand 211 and the third rope strand 221, and the second piece 42 detachably connects the second rope strand 212 and the fourth rope strand 222.

[0061] Specifically, Figure 5 As shown, the front half of the first rope strand 211 overlaps with the rear half of the third rope strand 221, and the first piece 41 is located between the front end of the first rope strand 211 and the rear end of the third rope strand 221, and the first piece 41 fastens and connects the overlapping portion of the front half of the first rope strand 211 and the rear end of the third rope strand 221; the front half of the second rope strand 212 overlaps with the rear half of the fourth rope strand 222, and the second piece 42 is located between the front end of the second rope strand 212 and the rear end of the fourth rope strand 222, and the second piece 42 fastens and connects the overlapping portion of the front half of the second rope strand 212 and the rear half of the fourth rope strand 222.

[0062] The first piece 41 fastens and connects the front half of the first rope strand 211 and the rear half of the third rope strand 221, thereby increasing the contact area between the first rope strand 211 and the third rope strand 221, thereby increasing the friction between the first rope strand 211 and the third rope strand 221. The second piece 42 fastens and connects the front half of the second rope strand 212 and the rear half of the fourth rope strand 222, thereby increasing the contact area between the second rope strand 212 and the fourth rope strand 222, thereby increasing the friction between the second rope strand 212 and the fourth rope strand 222.

[0063] Thus, the first end 21 and the second end 22 are connected by utilizing the friction between the first rope strand 211 and the third rope strand 221 and the friction between the second rope strand 212 and the fourth rope strand 222, thereby improving the connection effect between the first end 21 and the second end 22 and achieving a flexible connection between the first end 21 and the second end 22.

[0064] In some embodiments, the first rope strand 211 is located at one end of the first end 21 in the width direction of the conveyor belt 2, the second rope strand 212 is located at the other end of the first end 21 in the width direction of the conveyor belt 2, the third rope strand 221 is located at one end of the second end 22 in the width direction of the conveyor belt 2 and corresponds to the first rope strand 211, and the fourth rope strand 222 is located at the other end of the second end 22 in the width direction of the conveyor belt 2 and corresponds to the second rope strand 212.

[0065] Specifically, the first end 21 has a plurality of steel wire ropes arranged in parallel and at intervals along the width direction of the conveyor belt 2, the plurality of steel wire ropes on the rightmost side of the first end 21 are gathered to form a first rope strand 211, the plurality of steel wire ropes on the leftmost side of the first end 21 are gathered to form a second steel wire rope strand, the plurality of steel wire ropes on the rightmost side of the second end 22 are gathered to form a third rope strand 221, and the plurality of steel wire ropes on the leftmost side of the second end 22 are gathered to form a fourth rope strand 222.

[0066] Therefore, when the first end 21 and the second end 22 are connected, the distance between the combination of the first rope strand 211 and the third rope strand 221 and the combination of the second rope strand 212 and the fourth rope strand 222 is the largest. When the conveyor belt 2 is twisted, the stabilizing torque between the first end 21 and the second end 22 is increased to offset the tangential force when the conveyor belt 2 is twisted, thereby improving the stability of the conveyor belt 2 when it is flipped and preventing the conveyor belt 2 from falling off the belt conveyor 1.

[0067] In some embodiments, the belt conveyor 1 includes a frame 11, a tensioning mechanism 13, and a driving mechanism 12. The conveyor belt 2 is wrapped around the outer peripheral side of the frame 11 and rotates around the circumference of the frame 11. The driving mechanism 12 is located on one side of the length direction of the frame 11. The driving mechanism 12 is frictionally connected to the conveyor belt 2 to drive the conveyor belt 2 to rotate. The tensioning mechanism 13 is located between the driving mechanism 12 and the frame 11 to adjust the tightness of the fit between the belt and the frame 11.

[0068] Specifically, Figure 2 As shown, the frame 11 is provided with a plurality of rollers, which are rotatably connected to the frame 11, and are arranged in parallel and spaced apart along the length direction of the frame 11. The conveyor belt 2 is located on the upper side of the rollers and contacts the rollers. The rollers can rotate freely relative to the frame 11 so that the friction between the conveyor belt 2 and the frame 11 is rolling friction, thereby reducing the friction between the conveyor belt 2 and the frame 11.

[0069] In some embodiments, the plurality of rollers are detachably connected to the frame 11. When installing the plurality of turning rollers 3 on the frame 11, the plurality of rollers within a set interval are first removed, and then the plurality of turning rollers 3 are installed within the set interval.

[0070] Multiple turning rollers 3 are located on the upper surface of the frame 11 and are detachably connected to the frame 11. Therefore, when the conveyor belt 2 is turned over and reused, the multiple turning rollers 3 are placed on the frame 11 to drive the conveyor belt 2 to turn over. When the belt conveyor 1 works normally, the multiple turning rollers 3 are removed to avoid the conveyor belt 2.

[0071] The conveyor belt 2 is wrapped around the outer peripheral side of the frame 11 and connected with the upper groove roller, the unloading roller, the guide roller and the bottom groove roller. The conveyor belt 2 moves in a circle around the frame 11 to transport the material from the guide roller to the unloading roller.

[0072] The driving mechanism 12 includes a driving roller 121 , which is located at the rear end of the frame 11 . The conveyor belt 2 is wound around the outer circumference of the driving roller 121 and connected to the driving roller 121 so that the driving roller 121 can drive the conveyor belt 2 to rotate.

[0073] The tensioning mechanism 13 is located between the driving mechanism 12 and the frame 11 . The tensioning mechanism 13 includes a tensioning wheel. The outer peripheral side of the tensioning wheel is connected to the conveyor belt 2 . The position of the tensioning wheel relative to the frame 11 is adjustable to adjust the tension of the conveyor belt 2 .

[0074] In some embodiments, the driving mechanism 12 includes a driving roller 121, the conveyor belt 2 is located on the outer peripheral side of the driving roller 121 and is frictionally connected to the outer peripheral side of the driving roller 121, the tensioning mechanism 13 includes a tensioning roller 131, the outer peripheral side of the tensioning roller 131 is connected to the conveyor belt 2, and the position of the tensioning roller 131 relative to the frame 11 is adjustable to be suitable for adjusting the tensioning force of the conveyor belt 2.

[0075] Specifically, Figure 2 As shown, the driving roller 121 extends along the width direction of the frame 11, and one end of the driving roller 121 is connected to a motor (not shown in the figure). The driving roller 121 rotates under the drive of the motor. The tensioning roller 131 is located between the driving mechanism 12 and the frame 11. The tensioning roller 131 is located on the lower side of the conveyor belt 2. The tensioning roller 131 can move in the up and down directions. When the tensioning roller 131 moves upward, the conveyor belt 2 is tightened, and when the tensioning roller 131 moves downward, the conveyor belt 2 is loosened.

[0076] Therefore, the tensioning mechanism 13 can adjust the tightness of the fit between the conveyor belt 2 and the belt conveyor 1. Before cutting the conveyor belt 2 and vulcanizing the joint, the tensioning mechanism 13 loosens the conveyor belt 2 to facilitate cutting the conveyor belt 2 and vulcanizing the first end 21 and the second end 22. Before the conveyor belt 2 runs one circle, the tensioning mechanism 13 tightens the conveyor belt 2 to increase the friction between the driving roller 121 and the conveyor belt 2, so as to facilitate the driving mechanism 12 to drive the conveyor belt 2 to run one circle.
