Description

Technical Field

[0001] The utility model relates to the technical field of material conveying equipment, in particular to a forward and reverse conveyor. Background Art

[0002] In most industrial production processes, conveyors are needed to transport materials during or after production and processing. Existing belt conveyors require pre-buried foundations, which are inconvenient to move and disassemble. At the same time, most existing belt conveyors cannot discharge materials in both directions, but can only transport in one direction, which is inefficient and cannot meet diverse feeding needs.

[0003] Therefore, a bidirectional conveyor is developed, such as a mobile bidirectional discharging belt conveyor proposed in the patent with publication number CN108190388A. By setting a first electric roller and a second electric roller that can be actively rotated, the conveyor belt can realize conveying and transmission in two directions, the discharging is stable, and the material switching speed is fast. However, it still has one set of loading ports and two sets of discharging ports. Bidirectional feeding refers to the forward and reverse rotation of the belt, which transports the material from the loading port to the first discharging port and switches to the second discharging port, which cannot meet the use requirements of discharging in two directions at the same time.

[0004] Therefore, the patent with publication number CN105905525A proposes a belt conveyor capable of two-way transportation at the same time. By setting a transmission roller, the return section of the belt is pulled out from the bottom and extended to the side of the upper feeding section for reverse material transportation, achieving the effect of the same set of power to transport materials in two directions at the same time. However, the return section extended by the device cannot exceed the length range of the original feeding belt, and the scope of use is still limited. Because the device needs to pull the return section out through the transmission roller, the transmission belt can only be limited to the flexible belt. The upper and lower sections of the belt work at the same time, and the high load strength makes it easy to be damaged. Utility Model Content

[0005] The utility model aims to provide a forward and reverse conveyor to solve the technical problems that the existing bidirectional conveyor conveys materials in two directions at the same time, the conveying effect is limited, and the conveyor belt is easily damaged due to the flexibility of the conveyor belt.

[0006] The embodiments of the present invention are implemented by the following technical solutions:

[0007] A forward and reverse conveyor comprises a frame and a forward conveyor belt and a reverse conveyor belt arranged on the frame in different conveying directions, and also comprises a main driving shaft for driving the forward conveyor belt, the main driving shaft is drivingly connected to a first steering gear, the output shaft of the first steering gear is drivingly connected to a rotating shaft group, the rotating shaft group is drivingly connected to a second steering gear, and the second steering gear is drivingly connected to a secondary driving shaft for driving the reverse conveyor belt.

[0008] Preferably, the rotating shaft group includes a first rotating shaft and a second rotating shaft which are respectively transmission-connected to the first steering gear and the second steering gear, and the first rotating shaft and the second rotating shaft are transmission-connected via a transmission mechanism.

[0009] Preferably, the transmission mechanism includes a first coupling connecting the first rotating shaft and the second rotating shaft.

[0010] Preferably, the transmission mechanism further includes a second coupling and a self-aligning bearing seat connecting the first coupling and the second coupling, and the first coupling is connected to the second rotating shaft through the second coupling.

[0011] Preferably, the transmission mechanism further includes a second coupling and a third steering gear connecting the first coupling and the second coupling.

[0012] Preferably, it also includes a driving device, which is connected to the main driving shaft through a reducer.

[0013] Preferably, the positive conveyor belt and the reverse conveyor belt are configured as chain plates.

[0014] By adopting the technical scheme, only one set of driving devices is set, and the driving force is transmitted to another secondary driving shaft by adding a first steering gear, a second steering gear and a rotating shaft group through modification. By changing the direction of the steering gear, the rotation direction of the secondary driving shaft can be changed to be opposite to the rotation direction of the main driving shaft. When working, the driving device decelerates and increases the torque through the reducer, thereby increasing the rotation force of the main driving shaft and the secondary driving shaft. After the rotation is transmitted to the main driving shaft, the main driving shaft is transmitted to the first rotating shaft through the first steering gear, and the first rotating shaft is transmitted to the second rotating shaft through the transmission mechanism. The second rotating shaft is transmitted to this driving shaft to drive the reverse feeding belt to rotate. The setting of the first rotating shaft and the second rotating shaft can be designed according to the specific feeding length, and the forward and reverse feeding lengths are not restricted to each other. The modification and installation are simple. It is only necessary to install two sets of commutators on the side of the original conveyor belt to connect the driving shafts of the two conveyor belts respectively, and the two sets of commutators are connected through couplings and transmission mechanisms to complete the modification and installation. One set of driving devices is used to realize forward and reverse material transportation at the same time, thereby reducing the modification cost.

[0015] When the transmission mechanism is set as a self-aligning bearing seat, the first rotating shaft and the second rotating shaft are arranged in parallel to realize parallel forward and reverse conveying of materials;

[0016] The transmission mechanism can be set as an additional diverter to achieve vertical or inclined settings of the forward conveyor belt and the reverse conveyor belt, so that it can be applied to more usage scenarios.

[0017] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0018] 1. The utility model realizes the simultaneous conveying of forward and reverse materials through multiple sets of commutators and rotating shafts, and the forward and reverse feeding lengths are not restricted to each other, and the modification and installation are simple. One set of driving devices is used to simultaneously realize the forward and reverse material conveying, thereby reducing the modification cost;

[0019] 2. The transmission mechanism of the utility model can be set as another diverter to realize the vertical or inclined setting of the positive conveyor belt and the reverse conveyor belt, so that it can be applied to more usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment, the rotating shaft group includes a first rotating shaft 51 and a second rotating shaft 52 which are respectively connected to the first steering gear 41 and the second steering gear 42 , and the first rotating shaft 51 and the second rotating shaft 52 are connected to each other via a transmission mechanism.

[0034] In this embodiment, the transmission mechanism includes a first coupling 61 connecting the first rotating shaft 51 and the second rotating shaft 52 .

[0035] In this embodiment, the transmission mechanism further includes a second coupling 62 and a self-aligning bearing seat 63 connecting the first coupling 61 and the second coupling 62 , and the first coupling 61 is connected to the second rotating shaft 52 through the second coupling 62 .

[0036] In this embodiment, a driving device 2 is further included, and the driving device 2 is connected to the main driving shaft 21 via a reducer 7 .

[0037] In this embodiment, the positive conveyor belt 31 and the reverse conveyor belt 32 are configured as chain plates.

[0038] Working principle and usage process:

[0039] During installation, only one set of driving device 2 is provided. By modifying and adding the first steering gear 41, the second steering gear 42 and the rotating shaft group, the driving force is transmitted to another secondary driving shaft 22. By changing the direction of the steering gear, the rotation direction of the secondary driving shaft 22 can be changed to be opposite to the rotation direction of the main driving shaft 21.

[0040] During operation, the driving device 2 slows down and increases the torque through the reducer 7, thereby increasing the rotation force of the main driving shaft 21 and the secondary driving shaft 22.

[0041] Example 2

[0042] The only difference between this embodiment and the first embodiment is that, in this embodiment, the transmission mechanism does not include the self-aligning bearing seat 63 , but is replaced by a third steering gear 43 connecting the first coupling 61 and the second coupling 62 .

[0043] Working principle and usage process:

[0044] When working, the transmission mechanism can be set as another diverter to realize the vertical or inclined setting of the positive conveyor belt 31 and the reverse conveyor belt 32, so that it can be applied to more usage scenarios.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
