As shown in fig. 4 to 6, the welding conveyor 1 according to this embodiment has a structure and an operation principle substantially the same as those of the first embodiment, and includes a conveyor 16, a base 11, a fixed platform 13, a stepping platform 12, and a conveyor driving mechanism 15, and the conveyor driving mechanism 15 includes a driving roller 151, a first guide roller 152, a second guide roller 153, and a tension roller 154.

Unlike the first embodiment, in the conveyor belt driving mechanism 15 of the first embodiment, the second guide roller 153 is mounted at the bottom of the stepping platform 12, that is, the second guide roller 153 is hidden under the stepping platform 12. With this arrangement, the portion of the conveyor belt 16 wound around the second guide roller 153 is also hidden under the stepping platform 12, which eventually causes inconvenience in the installation and adjustment process of the conveyor belt 16. This second embodiment thus optimizes the conveyor belt drive mechanism 15 of the first embodiment.

For the sake of brevity, in this embodiment, we only make a specific description of the differences, and please refer to the relevant contents in the above first embodiment directly for the rest.

As shown in fig. 4 to 5, the welding conveying device 1 in this embodiment further includes a mounting bracket 123, a first end of the mounting bracket 123 is connected to the bottom of the stepping platform 12, a second end of the mounting bracket 123 extends outward to an end of the stepping platform 12 away from the fixed platform 13, and the second guide roller 153 is mounted at the second end of the mounting bracket 123 and located below the first guide roller 152, so that the second guide roller 153 is located outside the stepping platform 12.

As shown in fig. 6, by providing the mounting bracket 123 and indirectly mounting the second guiding roller 153 at the bottom of the stepping platform 12 through the mounting bracket 123, it can be ensured that the second guiding roller 153 extends outward to the outside of the stepping platform 12, and thus, the conveyor belt 16 wound around the second guiding roller 153 can also be exposed outside the stepping platform 12, thereby facilitating the installation and adjustment of the conveyor belt.

Third embodiment

The conveyor belt driving mechanism 15 in the first and second embodiments includes four roller structures, i.e., the drive roller 151, the first guide roller 152, the second guide roller 153, and the tension roller 154, and the structure is complicated. In the first and second embodiments, when the conveyor belt 16 passes around the second guide roller 153, the conveying surface (front surface) of the conveyor belt 16 directly contacts the second guide roller 153, and therefore the conveying surface of the conveyor belt 16 is easily worn by the second guide roller 153.

In view of the above, the present embodiment provides a conveyor belt driving mechanism with a simpler structure, and with the conveyor belt driving mechanism, the conveying surface of the conveyor belt 16 does not contact the guide rollers, thereby reducing the wear of the conveying surface of the conveyor belt and prolonging the service life of the conveyor belt.

The structure and the operation principle of the welding conveyor 1 provided in the present embodiment are similar to those of the first embodiment, and there are differences in that: the conveyor belt driving mechanism 15 in the present embodiment is different from the conveyor belt driving mechanism 15 in the first embodiment in terms of structure.

during the step of the stepping platform 12 away from the fixed platform 13, the rotating bracket 157 is configured to rotate toward the stepping platform 12, so that the part of the conveyor belt 16 extending in steps on the stepping platform 12 is the part of the conveyor belt released by the rotating bracket 157 through rotation, and meanwhile, the conveyor belt 16 is kept tensioned by the tensioning roller 158 on the rotating bracket 157; during the stepping of the stepping platform 12 towards the stationary platform 13, the rotating bracket 157 is configured to rotate away from the stepping platform 12, so that the extended portion of the conveyor belt 16 can be guided downwards by the tensioning rollers 158 and the guide rollers 159 on the rotating bracket 157 and keep the conveyor belt 16 tensioned.

In order to drive the rotating bracket 157 to rotate, a rotating bracket driving mechanism may be further provided in the present embodiment, and various known driving mechanisms may be adopted for the rotating bracket driving mechanism, such as a driving cylinder, and the like, and this embodiment is not particularly limited thereto.

As can be seen, in the present embodiment, the structure of the conveyor belt driving mechanism 15 provided with the drive roller 151, the guide roller 159, the tension roller 158, and the rotating bracket 157 is simpler and maintenance is facilitated.
