Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of telescopic machines, in particular to a novel encrypted telescopic conveyor. Background Art
[0002] Telescopic conveyors are flexible and convenient, and do not take up space. When needed, they can be stretched out and used as ordinary conveyors. They can also be bent for conveying. When not in use, they can be retracted and placed, and do not take up space. However, existing telescopic conveyors have the following disadvantages: the distance between adjacent rollers is fixed, and sometimes during the conveying process, materials fall from between adjacent rollers. They cannot be used universally for different conveyed items. As the telescopic conveyor is pulled open, the roller spacing increases. It is not convenient for conveying small items. There are also encrypted telescopic conveyors on the market, but when the encrypted telescopic conveyor is just opened, the auxiliary rollers rise slowly, and the roller spacing is still large; the later lifting is large, and the stretching is 1mm, the corresponding lifting number is very small, and the actual use range is very small. In order to overcome this defect, a variety of mechanisms have also been designed, such as segmented stretching, but the structure is complex, the failure is frequent, and the cost is high. Therefore, it is necessary to improve the existing conveyor.
[0003] To this end, we propose a new type of encrypted telescopic conveyor. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The novel encrypted telescopic conveyor is provided with a lifting rod and a limit block. When the conveyor is lengthened, the two follower rotating rods rotate with the first bracket and the second bracket, so that the lifting rod rises along the slide groove and the fixed slider, and then the supporting slider and the rotating shaft are pushed up by the lifting spring. At the same time, the rocker arm rotates, and the rotation of the rocker arm makes the height of the limit block remain the same as that of the main roller. When the first bracket and the second bracket rotate to a large distance between two adjacent main rollers, the auxiliary roller is inserted between the adjacent main rollers under the action of the lifting spring to adapt to the conveying of small items. Then the upper section of the auxiliary roller is limited by the limit block to be on the same plane as the upper section of the main roller, so that the stretching range can be very large.
[0014] The novel encrypted telescopic conveyor is provided with a limit block. When the height of the auxiliary roller is raised to the same height as the main roller, the rotating shaft is inserted into the limit slot. When the first bracket and the second bracket continue to stretch, the limit block remains unchanged in height under the pull of the swing rod. As the lifting rod rises, a sliding connection is formed between the lifting rod and the two limit protrusions. The height of the auxiliary roller is limited by the limit block. When the conveyor is folded up, the follower rotating rod pulls the lifting rod downward, so that when the rotating shaft and the supporting slider slide to the top of the sliding slot, they are pulled to the bottom of the main roller by the lifting rod.

A lifting spring 9 is arranged between the fixed slider 8 and the supporting slider 10. By arranging the lifting rod 5 and the limit block 14, when the conveyor is stretched, the two follower rotating rods 4 rotate with the first bracket 1 and the second bracket 2, so that the lifting rod 5 rises along the slide groove and the fixed slider 8, and then the supporting slider 10 and the rotating shaft 11 are pushed up by the lift spring 9, and the rocker arm 13 rotates at the same time, and the rotation of the rocker arm 13 makes the height of the limit block 14 remain the same as that of the main roller 3. When the first bracket 1 and the second bracket 2 rotate to a large distance between two adjacent main rollers 3, the auxiliary roller 12 is inserted between the adjacent main rollers 3 under the action of the lift spring 9 to adapt to the transportation of small items, and then the upper section of the auxiliary roller 12 is limited by the limit block 14 to be on the same plane as the upper section of the main roller 3, so that the stretching range can be very large.
[0022] The bottom of the lifting spring 9 is fixedly installed with the top of the fixed sliding block 8 , and the top of the lifting spring 9 is tightly arranged with the bottom of the supporting sliding block 10 .
[0023] The first bracket 1 and the second bracket 2 have the same length, the auxiliary roller 12 has the same diameter as the main roller 3 , and the auxiliary roller 12 is located between two adjacent main rollers 3 .
[0024] The two ends of the limit block 14 are rotatably connected to the tops of the two swing rods 13 , respectively. The two swing rods 13 are symmetrically arranged at the two ends of the limit block 14 .
[0025] A limiting protrusion 16 is integrally provided on one side of the limiting block 14 . The thickness of the limiting protrusion 16 is the same as that of the lifting rod 5 .

When the first bracket 1 and the second bracket 2 continue to stretch, the limiting block 14 remains in a constant height under the pull of the rocker arm 13. As the lifting rod 5 rises, a sliding connection is penetrated between the lifting rod 5 and the two limiting protrusions 16, and the height of the auxiliary roller 12 is limited by the limiting block 14. When the conveyor is folded up, the follower rotating rod 4 pulls the lifting rod 5 downward, so that when the rotating shaft 11 and the supporting slider 10 slide to the top of the sliding groove 6, they are pulled to the bottom of the main roller 3 by the lifting rod 5.
[0027] The bottom of the sliding groove 6 is located above the rotation connection of the follower rotating rod 4 , and the length of the lifting rod 5 is smaller than the length of the first bracket 1 .
[0028] Working principle:
[0029] When the conveyor is extended, the two follower rotating rods 4 rotate with the first bracket 1 and the second bracket 2, so that the lifting rod 5 rises along the slide groove and the fixed slider 8, and then the supporting slider 10 and the rotating shaft 11 are pushed up by the lifting spring 9. At the same time, the swing rod 13 rotates, and the height of the limit block 14 is kept the same as that of the main roller 3 through the rotation of the swing rod 13. When the first bracket 1 and the second bracket 2 rotate to the distance between the two adjacent main rollers 3 is larger, the auxiliary roller 12 is inserted between the adjacent main rollers 3 under the action of the lifting spring 9. When the height of the auxiliary roller 12 is raised to the same height as the main roller 3, the rotating shaft 11 is locked. In the limiting slot 15, when the first bracket 1 and the second bracket 2 continue to stretch, the limiting block 14 remains in height under the pull of the rocker arm 13. As the lifting rod 5 rises, the lifting rod 5 is slidably connected with the two limiting protrusions 16, and the height of the auxiliary roller 12 is limited by the limiting block 14 to adapt to the conveying of small items. Then, the upper section of the auxiliary roller 12 is limited by the limiting block 14 to be on the same plane as the upper section of the main roller 3, so that the stretching range can be very large. When the conveyor is folded up, the follower rod 4 pulls the lifting rod 5 downward, so that when the rotating shaft 11 and the supporting slider 10 slide to the top of the sliding groove 6, they are pulled to the bottom of the main roller 3 by the lifting rod 5.
