Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1, a rubber conveyor belt for preventing a work from falling down includes a frame 1.

As shown in fig. 1 to 4, a conveyor belt body 2 for conveying a workpiece 22 is provided on the frame 1, and a driving device 3 for driving the conveyor belt body 2 to convey is further provided on the frame 1. The specific transmission connection between the driving device 3 and the belt body 2 is conventional, and in this embodiment, it will not be described in detail. In order to stably convey the workpiece 22, the outer surface of the conveyor belt body 2 is provided with a plurality of baffle plates 4 at equal intervals. When the conveyor belt is used, the workpiece 22 is placed between the two baffle plates 4, the workpiece 22 is abutted against the side wall of the subsequent baffle plate 4 in the conveying direction relative to the conveyor belt body 2, and the baffle plate 4 can stably push the workpiece 22 to convey under the driving of the conveyor belt body 2.

It should be noted that, for convenience of description and understanding, the side wall of the baffle 4 and the side wall of the conveyor belt body 2 in the same conveying direction is defined as the interference surface 5 in the present embodiment.

In order to prevent the workpiece 22 from falling down during the conveying process, the abutting surface 5 is provided with a clamping mechanism 6 for clamping the workpiece 22. Further, the clamping mechanism 6 comprises two clamping plates 7 slidably connected to the abutting surfaces 5. When the workpiece 22 abuts against the abutting surface 5, the two clamping plates 7 can slide towards each other, so that the workpiece 22 in the middle is clamped, and the workpiece 22 is prevented from falling. Meanwhile, in order to improve the usability of the clamping plates 7, a driving assembly 8 for driving the two clamping plates 7 to slide towards each other is further arranged on the baffle plate 4.

Specifically, be provided with installation cavity 9 in the baffle 4, above-mentioned drive assembly 8 is including sliding the connection on conflict face 5 to can be to the gliding actuating lever 10 of installation cavity 9 inside one side. And both sides of the driving rod 10 in the mounting cavity 9 are rotatably connected with a first gear 11, and both side walls of the driving rod 10 facing the two first gears 11 are provided with a first tooth-shaped structure 12, and the first tooth-shaped structure 12 is meshed with the first gear 11 on the same side. Obviously, the sliding driving rod 10 can drive the gear 11 to rotate through the tooth structure one 12. And a cable 13 is connected between the first gear 11 and the clamping plate 7 on the same side, and when the first gear 11 rotates, the cable 13 can be wound or unfolded according to the corresponding rotating direction.

The specific process of the driving assembly 8 driving the two clamping plates 7 to slide towards each other will be explained below. That is to say that the temperature of the molten steel,

during the abutment of the workpiece 22 against the abutment surface 5, the workpiece 22 presses the drive rod 10 into the mounting chamber 9. The sliding driving rod 10 drives the two gears one 11 to rotate through the first tooth-shaped structure 12, and the rotating gears one 11 wind the cable 13, so that the cable 13 is continuously tightened, and the two clamping plates 7 are driven to move towards each other, so as to realize stable clamping of the workpiece 22.

In order to enable the two clamping plates 7 and the driving rod 10 to automatically return to the initial positions when the workpiece 22 is separated, a first return spring 14 is connected between the two clamping plates 7, and a second return spring 15 is arranged between the driving rod 10 and the inner wall of the mounting cavity 9. The first return spring 14 has an elastic force that pushes the two clamp plates 7 away from each other, and the second return spring 15 has an elastic force that pushes the drive rod 10 away from the mounting cavity 9. It should be noted that the elastic force of the second return spring 15 should not be too strong, and only needs to be enough to push the driving rod 10 to the initial position again. In other words, when the workpiece 22 pushes the driving rod 10 into the mounting cavity 9, the elastic force of the second return spring 15 is sufficient for the usability of not pushing the workpiece 22 away from the baffle 4.

It will be appreciated that in the above arrangement, a relative movement of the workpiece 22 and the shutter 4 is required to drive the drive rod 10 into the mounting cavity 9. Thus, in practical applications, the worker is required to manually push the workpiece 22 to press the driving rod 10 into the mounting cavity 9, which is inconvenient in use.

Aiming at the problems, the two side walls of the conveyor belt body 2 are provided with the plurality of second tooth-shaped structures 16 at intervals, and the second tooth-shaped structures 16 on the two sides are symmetrical structures. In other words, the second tooth structures 16 on the two sides have a one-to-one corresponding position relationship. Meanwhile, the two sides of the conveyor belt body 2 of the frame 1 are rotatably connected with a second gear 17, and the two second gears 17 are in a relative position relationship. The second gear 17 is configured to be capable of engaging with the second toothed structure 16 on the same side, so that when the second toothed structure 16 moves along one side of the conveying direction under the driving of the conveyor belt body 2, the second toothed structure 16 engages with the second gear 17, and the second gear 17 is driven to rotate. And a gear third 18 is coaxially arranged on the gear second 17, and the gear third 18 can rotate along with the rotation of the gear second 17. In addition, the rack 19 which can slide into the conveyor belt body 2 is also connected to the two sides of the conveyor belt body 2 of the frame 1 in a sliding manner, and the rack 19 is meshed with the gear wheel III 18 on the same side.

The specific transmission process and the use effect of the above structure will be explained below. That is to say that the first and second electrodes,

the second toothed structure 16 drives the second gear 17 to rotate under the driving of the conveyor belt body 2, and at this time, the third gear 18 rotates together with the second gear 17, so as to drive the two racks 19 to slide towards one side of the conveyor belt body 2 simultaneously. When the two racks 19 slide in opposite directions, the two racks 19 can clamp the workpiece 22 therebetween, so that the workpiece 22 has a fixed position relative to the baffle 4, that is, the baffle 4 is driven by the conveyor belt body 2 to move toward the workpiece 22. In the process, the workpiece 22 presses the driving rod 10 into the mounting cavity 9, so that the two clamping plates 7 move towards each other to clamp the workpiece 22.

Thus, during use of the conveyor, the worker does not need to manually hold the workpiece 22 to push the drive rod 10, but merely places the workpiece 22 between the two blocking plates 4 and slightly adjusts the desired orientation of the workpiece 22.

It is worth mentioning that the opposite ends of the two racks 19 are provided with elastic portions 20. The elastic portion 20 can compensate for the stroke of the rack 19. The principle is as follows: when the two racks 19 already clamp the workpiece 22, since the baffle 4 needs to move to the workpiece 22 side to push the driving rod 10 into the installation cavity 9, and the racks 19 still have a tendency to slide toward each other under the driving of the third gear 18, the sliding racks 19 press the elastic portion 20, so that the racks 19 and the third gear 18 are not easily interfered. Preferably, the elastic part 20 includes a rubber block.

In addition, in order to achieve self-resetting of the rack 19, a return spring three 21 is provided in the slide chamber of the rack 19, and the return spring three 21 acts with an elastic force that pulls the rack 19 back into the slide chamber. When the second toothed structure 16 is disengaged from the second gear 17, the third return spring 21 will return to its natural state, thereby drawing the rack 19 back into the sliding cavity for clamping the next workpiece 22. And at this moment, the two racks 19 no longer have clamping force on the workpiece 22, and the baffle 4 can smoothly drive the workpiece 22 to be conveyed.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise form disclosed herein and is not to be construed as limited to the exclusion of other embodiments, and that various other combinations, modifications, and environments may be used and modifications may be made within the scope of the concepts described herein, either by the above teachings or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
