Description
Technical Field
[0001] This utility model belongs to the technical field of electric roller belt conveyors, specifically relating to an electric roller belt conveyor with a tensioning structure. Background Technology
[0002] A transmission belt conveyor generally refers to a mechanical device that uses a transmission belt (also known as a drive belt, synchronous belt, rubber belt, etc.) to transmit power and motion. Its working principle is based on friction, transmitting power through the friction between the belt and the drive and driven pulleys. In existing belt conveyor technology, especially in the field of electric roller belt conveyors, although the equipment is widely used in various material conveying scenarios, in certain specific environments, such as confined factory spaces, traditional belt conveyors, due to their fixed length, are difficult to flexibly adapt to space requirements. Furthermore, when two or more belt conveyors need to be used in conjunction, the curved design of the belt ends makes it easy for square packaging boxes to get stuck at the joint during transport, leading to poor or no transport. This has become a significant factor restricting the application range and efficiency of belt conveyors. Therefore, we propose an electric roller belt conveyor with a tensioning structure.

The tensioning roller 9 is connected to the tensioning mechanism box 4. Hydraulic cylinders 10 connected to both sides of the tensioning roller 9 are symmetrically fixed at the bottom of the box. Belts 11 are sequentially sleeved on the surfaces of the drive roller 5, transmission roller 6, and tensioning roller 9 on the inner sides of the first outer baffle 1 and the second outer baffle 2. The belts 11 are in close contact with the auxiliary roller 7. The hydraulic cylinder drives the tensioning roller to move along the slide groove, and the belt tension is quickly adjusted in conjunction with the auxiliary roller to adapt to changes in length or slack after long-term use. A belt length adjustment mechanism is provided between the first outer baffle 1 and the second outer baffle 2. The belt length adjustment mechanism includes a telescopic component and a locking component.
[0022] In this embodiment, preferably, the telescopic component includes a connecting groove 100 symmetrically opened at the end of the first outer baffle 1 and a connecting rod 101 symmetrically fixed at the end of the second outer baffle 2. The connecting rod 101 is slidably connected to the connecting groove 100, which can flexibly adjust the length of the belt conveyor according to the space requirements of the actual use scenario.
[0023] In this embodiment, preferably, guide grooves 200 are symmetrically provided on both sides of the connecting rod 101, and guide blocks 201 are symmetrically fixed on the inner wall of the connecting groove 100, and the guide blocks 201 are engaged with the guide grooves 200.
[0024] In this embodiment, preferably, the locking assembly includes locking holes 300 evenly spaced on the surface of the connecting rod 101 and screw holes 301 penetrating through the side of the first outer baffle 1. The side of the first outer baffle 1 is provided with a locking rod 302 that penetrates through the screw hole 301 and connects to the locking hole 300. The locking rod 302 is screwed and fixedly connected to the locking hole 300.
[0025] In this embodiment, preferably, the end of the second outer baffle 2 is provided with a splicing auxiliary feeding mechanism. The splicing auxiliary feeding mechanism includes a clamping plate 400 provided at the end of the second outer baffle 2. A flat plate 401 is fixed inside the clamping plate 400. Rotatable auxiliary feeding rollers 402 are connected at equal intervals on the inner side of the flat plate 401. Rotation holes are symmetrically opened through both sides of the clamping plate 400.
[0026] In this embodiment, preferably, the two sides of the second outer baffle 2 are symmetrically fixed with fixing seats 500, and the surface of the fixing seat 500 is fixed with fixing screws 501. The clamping plate 400 is sleeved on the surface of the fixing screws 501 through the rotating hole, and the square packaging box is smoothly guided to transition through the splicing seam by the rotatable auxiliary material passing roller, avoiding jamming.
[0027] In this embodiment, preferably, a fixing nut 502 that is screwed onto the surface of the fixing screw 501 and fits into the clamping plate 400 is provided. The design of the clamping plate 400 and the fixing screw 501 facilitates angle adjustment and fixation, thereby improving adaptability.
[0028] The working principle and usage process of this utility model are as follows: When using belt conveyors in small factory buildings, where there is only a small amount of space available, making it impossible to fit two belt conveyors together, the length of one of the belt conveyors can be shortened to meet the usage requirements. First, loosen the locking rods 302 on both sides of the first outer baffle 1, causing their ends to unscrew from the locking holes 300 and retract into the screw holes 301, thus releasing the positioning of the connecting rod 101. Then, push the second outer baffle 2, causing it to slide the connecting rod 101 into the connecting groove 100. The guide groove 200 slides on the surface of the guide block 201 to provide a guiding function. When the second outer baffle 2 is moved to a suitable position to meet the placement requirements, the second outer baffle 2 is stopped from being pushed, causing the connecting rod 101 to stop moving in the connecting groove 100. The locking hole 300 at the adjusted position is aligned with the screw hole 301. Then, the locking rods 302 on both sides of the first outer baffle 1 are tightened, causing them to rotate inside the screw hole 301 and engage with the locking hole 300 for a fixed connection. This locks and positions the connecting rod 101 inside the connecting groove 100, completing the length adjustment of the first outer baffle 1. Then, the... The hydraulic cylinder 10 inside the tensioning mechanism box 4 retracts the hydraulic rod, causing the tensioning roller 9 to move downwards through the slide groove 8 inside the tensioning mechanism box 4. This, in conjunction with the auxiliary roller 7, tensions the belt 11 fitted onto the surfaces of the drive roller 5 and transmission roller 6, completing the tension adjustment. The adjusted belt conveyor can then be spliced with another belt conveyor. However, because the ends of the belts at the splice point of the two belt conveyors are curved, when conveying some square packaging boxes, the boxes may get stuck at the belt splice point and repeatedly roll, preventing further conveying. In this case, the fixing screws can be loosened. Tighten the fixing nut 502 inside the fixing screw 501 to loosen it and separate it from the clamping plate 400, thus releasing the locking of the clamping plate 400. Then, rotate the clamping plate 400 inside the fixing screw 501 and embed the flat plate 401 inside the clamping plate 400 into the splice of the two belt conveyors. Then, tighten the fixing nut 502 so that it rotates and tightens inside the fixing screw 501 and is pressed and fixed to the clamping plate 400. This locks the angle position of the clamping plate 400, so that the square packaging box can be smoothly transported to the other belt conveyor by the auxiliary feeding roller 402 inside the flat plate 401 in conjunction with the belt conveyor at the splice.
