Description

Technical Field

[0001] The utility model relates to the technical field of roller beds, and particularly relates to a differential roller bed conveying roller which is convenient to adjust. Background Art

[0002] At present, the movement mode of the roller group of the roller bed is an active and driven structure, that is, the motor drives the active roller to run, and the active roller drives the driven roller to run through a belt or a chain, etc., and the material is conveyed on the belt or the chain. This transmission mode is that the driving roller drives the driven roller to run as a whole, and has relatively high requirements for the driving part. The working section area is modular, and the function of a single working section is relatively single. It is often difficult to program the movement track of the roller bed, and multi-stage speed change cannot be realized during the transportation process of the roller bed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a differential roller bed conveying roller which is convenient to adjust, so as to solve the problems existing in the above-mentioned prior art.

[0004] The above technical purpose of the utility model is realized through the following technical solutions:

[0005] A differential roller bed conveying roller which is convenient to adjust includes a roller bed body, a plurality of motors arranged at equal intervals from left to right on the front side of the roller bed body, a plurality of roller groups corresponding to the rotating shafts of the plurality of motors arranged close to the roller bed side one by one, and a control module fixedly installed on one side of the roller bed body. A plurality of first mounting holes are arranged at equal intervals from left to right on the front side of the roller bed body, and a plurality of second mounting holes are arranged at equal intervals from left to right on the rear side of the roller bed body. The positions of the plurality of motors correspond to the positions of the plurality of first mounting holes one by one, and the positions of the plurality of first mounting holes and the plurality of second mounting holes correspond to each other one by one. A first bearing seat is coaxially arranged on the front side of each of the plurality of first mounting holes, and the first bearing seat is fixedly connected with the roller bed body. A second bearing seat is coaxially arranged on the rear side of each of the plurality of second mounting holes, and the second bearing seat is fixedly connected with the roller bed body;

[0006] The roller group includes a first short driving roller, a second short driving roller and a coupling. The first short driving roller is rotatably installed in the first mounting hole, the front end of the first short driving roller is fixedly connected with the rotating shaft of the motor, a first driving wheel is welded on the first short driving roller, the rear end of the first short driving roller is fixedly connected with the front end of the coupling, the rear end of the coupling is fixedly connected with the front end of the second short driving roller, and the rear end of the second short driving roller is rotatably installed in the second bearing seat. A second driving wheel is welded on the second short driving roller;

[0007] The control module is electrically connected with the plurality of motors through wires.

[0008] By adopting the above technical solution, the roller bed only needs to rely on the driving roller driven by a single motor to operate. The entire roller group consists of two short driving rollers and a coupling. The driving wheel is welded on the short driving roller. The material does not need to be transported by belt drive. It can be directly transported by contacting the driving wheel. One advantage of this transportation method is that it can avoid the loss of force during the belt drive process and reduce consumption. Another advantage is that the running speed of each motor can be regulated through the control module, so as to realize the transportation of different roller groups at different speeds, and thus realize many functions. After the transmission tasks are assigned to each individual driving wheel, the requirements for the driving wheel and the motor are also reduced, and it is no longer necessary for the entire conveyor belt to rely on a single driving wheel to operate as before.

[0009] In a further embodiment, a plurality of brackets are provided on the roller bed body. Brackets are spaced at intervals on the left side of the plurality of roller groups, and the brackets are arranged parallel to the roller groups. The front side of the bracket is fixedly installed on the inner side wall of the front side of the roller bed, and the rear side of the bracket is fixedly installed on the inner side wall of the rear side of the roller bed.

[0010] By adopting the above technical solution, the bracket is fixed on the roller bed. Its main function is to be able to hoist objects such as short driving rollers and couplings by hoisting during the installation and maintenance of the roller group, so as to avoid the workpiece directly falling to the ground and causing damage to personnel or equipment.

[0011] In a further embodiment, a first retaining ring is welded on the front side of the first driving wheel, and an acute angle chamfering structure is provided on the outer edge of the rear side of the first retaining ring. A second retaining ring is welded on the rear side of the second driving wheel, and an acute angle chamfering structure is provided on the outer edge of the rear side of the second retaining ring.

[0012] By adopting the above technical solution, both the first retaining ring and the second retaining ring are used to limit the offset of the material during the transportation process on the driving wheel or the overall roller bed, improving the overall stability of the roller bed.

[0013] In a further embodiment, a first synchronous pulley is welded on the front side of the first driving wheel, and a second synchronous pulley is welded on the front side of the second driving wheel. A third mounting hole is provided between every two adjacent first mounting holes. A plurality of third mounting holes are horizontally arranged at equal intervals on the front side of the roller bed body. A fourth mounting hole is provided between every two adjacent second mounting holes. A plurality of fourth mounting holes are horizontally arranged at equal intervals on the rear side of the roller bed body. The positions of the plurality of third mounting holes correspond to those of the plurality of fourth mounting holes one by one.

[0014] By adopting the above technical solution, the synchronous pulley welded on the short driving roller is mainly for convenient combined use in a small range. For example, belt drive is adopted for a certain section, while for those with higher requirements for running track, speed, and acceleration, driving wheel drive can be adopted, which also facilitates the realization of some complex operation requirements and the sharing of production lines by multiple vehicle models.

[0015] In a further embodiment, third bearing seats are coaxially arranged on the front sides of the multiple third mounting holes. The third bearing seats are fixedly connected to the roller bed body. Fourth bearing seats are coaxially arranged on the front sides of the multiple fourth mounting holes. The fourth bearing seats are fixedly connected to the roller bed body. The front end of the driven roller is rotatably installed in the third bearing seat, and the rear end of the driven roller is rotatably installed in the fourth bearing seat. A first driven wheel is welded to the front end of the driven roller, and a second driven wheel is welded to the rear end of the driven roller.

[0016] By adopting the above technical solution, the transmission wheel can play a good auxiliary role relative to the driving wheel.

[0017] In a further embodiment, a first auxiliary synchronous pulley is welded to the front side of the first driven wheel, and a second auxiliary synchronous pulley is welded to the front side of the second driven wheel.

[0018] By adopting the above technical solution, in addition to the synchronous pulley being required on the roller group driven by the motor, in order to drive the driven roller, a synchronous pulley also needs to be provided on the driven roller, so that it can be driven after installing the synchronous belt.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. Through the setting of the control module and the roller group, each roller group can be equipped with a motor separately, and the integrated programming of the running track, speed, and acceleration can be realized through the control module, achieving the effect of realizing the complex operation requirements of the roller bed transportation and improving the flexibility of the production line;

[0021] 2. Through the setting of the driven roller, it can be combined and used within a small range on the entire roller bed, and part of it is adjusted to the synchronous belt connection structure of the driving roller and the driven roller, achieving the effect of improving the transportation flexibility.
