[0025] The utility model discloses a chain track section automatic uniform material distribution device, such as Figure 1 As shown, it includes a conveyor belt 1, a guide rail 2 and an automatic positioning device 3, and the guide rail 2 and the automatic positioning device 3 are arranged on both sides of the conveyor belt 1. The automatic positioning device 3 performs telescopic movement relative to the guide rail 2 at a preset frequency. When the automatic positioning device 3 is extended, it cooperates with the guide rail 2 to limit the movement of the chain track segments on the conveyor belt 1. When the automatic positioning device 3 is retracted, the restriction on the chain track segments on the conveyor belt 1 is released, so that the distance between the chain track segments on the conveyor belt 1 is uniform.

[0026] like Figure 2 As shown, in some embodiments, the automatic positioning device 3 includes a pushing mechanism 5, and a positioning adjustment plate 4 is provided at one end of the pushing mechanism 5. A vertical first positioning groove 41 and a second positioning groove 43 along the axial direction of the conveyor belt 1 are provided on the side of the positioning adjustment plate 4 close to the conveyor belt 1, and a first positioning pin 42 is slidably connected in the first positioning groove 41, and a second positioning pin 44 is slidably connected in the second positioning groove 43. By the second positioning pin 44 sliding horizontally in the second positioning groove 43, the spacing between the front and rear chain track sections can be adjusted. Among them, the second positioning groove 43 includes a plurality of positioning grooves distributed vertically along the axial direction of the conveyor belt 1. By the first positioning pin 42 sliding vertically in the first positioning groove 41, and selecting the second positioning grooves 43 in different vertical directions, chain track sections of different models can be matched.

[0027] like Figure 3-4 As shown, in some embodiments, the pushing mechanism 5 includes a base 51, and a cylinder 53 and two sliding guide rails 54 parallel to the cylinder 53 are connected to the base 51. The base 51 includes a bottom plate 511, a vertical plate 512 and a cylinder seat 52. The sliding guide rails 54 are fixedly arranged on the vertical plate 512 through the guide rail mounting holes 513, and the two sliding guide rails 54 are respectively provided with positioning telescopic rods 55 slidably connected thereto, and one end of the positioning telescopic rods 55 is fixedly connected to the positioning adjustment plate 4. The cylinder seat 52 is fixedly arranged on the vertical plate 512 through fasteners, and includes a cylinder bracket 521 and a cylinder connecting plate 523, and the cylinder connecting plate 523 is provided with a bracket mounting hole 522, and the cylinder bracket 521 is fixedly connected to the vertical plate 512 through the bracket mounting hole 522. The cylinder 53 includes a cylinder barrel fixed on the cylinder seat 52 and a cylinder telescopic rod 531 that can telescope and slide relative to the cylinder barrel. Preferably, the cylinder 53 adopts a thin cylinder. One end of the cylinder telescopic rod 531 passes through the vertical plate 512 and is connected to the positioning adjustment plate 4. The telescopic movement of the cylinder telescopic rod 531 drives the positioning adjustment plate 4 to reciprocate relative to the guide rail 2. When the cylinder telescopic rod 531 drives the positioning adjustment plate 4 to extend, the first positioning pin 42 and the second positioning pin 44 cooperate with the guide rail 2 to limit the movement of the chain track segment on the conveyor belt 1. When the cylinder telescopic rod 531 drives the positioning adjustment plate 4 to retract, the restriction on the chain track segment on the conveyor belt 1 is released, so that the chain track segment spacing on the conveyor belt 1 is uniform.

[0028] In some embodiments, a positioning assembly 56 is provided at one end of the positioning telescopic rod 55 away from the positioning adjustment plate 3, and the positioning assembly 56 includes a positioning plate 561, and a length-adjustable positioning bolt 562 is provided inside the positioning plate 561. When the cylinder telescopic rod 531 drives the positioning adjustment plate 4 to extend, the positioning bolt 562 cooperates with the vertical plate 512 of the base 51 to define the distance between the positioning adjustment plate 4 and the guide rail 1. At the same time, by adjusting the length of the positioning bolt 562, the distance between the positioning adjustment plate 4 and the guide rail 1 can be adjusted.

[0029] In some embodiments, a limit block 57 is provided in the middle of the positioning telescopic rod 55. When the cylinder telescopic rod 531 drives the positioning adjustment plate 4 to extend or retract, the limit block 57 cooperates with the sliding guide rail 54 to limit the maximum stroke of the positioning telescopic rod 55 to protect the automatic positioning device 3.

[0030] In some embodiments, the automatic uniform distribution device for the chain track further includes a controller and a sensor, wherein the controller is electrically connected to the cylinder 53 and is used to control the cylinder 53 to operate at a preset frequency. The sensor is electrically connected to the controller and is used to obtain the position of the chain track on the conveyor belt 1 and transmit relevant data to the controller.

[0031] When the track segment starts to be laid through the conveyor belt 1, the automatic uniform material distribution device of the track segment recognizes the feeding through the sensor. After a predetermined time, the controller controls the pushing mechanism 5 to act, and drives the positioning adjustment plate 4 to approach the guide rail 1 through the cylinder 53, which is used to constrain the gaps on both sides of the track segment. The first and second track segments adjacent to each other in front and back stop after encountering the first positioning pin 42 and the second positioning pin 44, respectively, to locate the positions of the two track segments. After a predetermined time, the pushing mechanism 5 is reset, and the positioning adjustment plate 4 is driven to retract through the cylinder 53, and the first and second track segments on the conveyor belt 1 continue to move forward. After a predetermined time, the pushing mechanism 5 is activated again. At this time, the first track segment has left the range of the positioning adjustment plate 4 and continues to move forward on the conveyor belt 1. The second track segment stops after moving to the second positioning pin 44, and the third track segment stops after moving to the first positioning pin 42. Through the repeated actions of the pushing mechanism 5 at a preset frequency, it is ensured that the track segments on the conveyor belt 1 always start to move from the first positioning pin 42 and the second positioning pin 44, so that the spacing between the adjacent track segments in front and back is always consistent. When in use, the spacing between the positioning adjustment plate 4 and the guide rail 1 can be adjusted by adjusting the positioning bolt 562 to control the gap between the chain track segment and the sensor. Chain track segments of different sizes can be matched by vertically sliding the first positioning pin 42 in the first positioning groove 41 and selecting the second positioning groove 43 in different vertical directions. The spacing between the front and rear chain track segments on the conveyor belt 1 can be adjusted by horizontally sliding the second positioning pin 44 in the second positioning groove 43.

[0032] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
