[0024] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The expandable conveying device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, the expandable conveying device of the embodiment of the present invention may include a first mounting frame 100 , a second mounting frame 200 , a transmission roller set 300 , an adjustment roller set 400 , a guide roller set 500 , a transmission belt 600 and an electric telescopic rod 700 .

[0027] The first mounting bracket 100 is slidably connected to the second mounting bracket 200 and is locked by quick release.

[0028] The two transfer roller sets 300 are rotatably disposed in the first mounting frame 100 and the second mounting frame 200 , respectively.

[0029] It should be noted that a drive motor 301 is also provided on the first mounting frame 100, and the output end of the drive motor 301 is connected to the transmission roller group 300 on the first mounting frame 100. In addition, to ensure transmission stability, the two transmission roller groups 300 can be maintained at the same horizontal height.

[0030] The two adjusting roller groups 400 are respectively slidably arranged in the first mounting frame 100 and the second mounting frame 200 and can be locked. Relevant staff can adjust the position of the adjusting roller group 400 to a suitable height as needed and then lock it.

[0031] The guide roller set 500 is disposed above between the two adjustment roller sets 400 and is rotatably disposed between the second mounting frames 200 .

[0032] The transmission roller set 300 , the adjustment roller set 400 and the guide roller set 500 are all length-adjustable roller sets. The transmission belt 600 connects the two transmission roller sets 300 , the two adjustment roller sets 400 and the guide roller set 500 .

[0033] As a possible scenario, Figure 4 As shown, the transmission roller set 300 , the adjustment roller set 400 and the guide roller set 500 each include a shaft sleeve 310 , a rotating shaft 320 , a rotating roller 330 and a limiting structure 340 .

[0034] Among them, the sleeve 310 is mounted on the rotating shaft 320 through an axial limiting structure 340 to ensure that the sleeve 310 and the rotating shaft 320 rotate synchronously. The sleeve 310 is slidably connected along the length direction of the rotating shaft 320 to achieve length adjustment. The two rotating rollers 330 are respectively arranged on the rotating shaft 320 and the sleeve 310, wherein the two rotating rollers 330 are both equipped with a transmission belt 600.

[0035] The electric telescopic rod 700 is disposed in the second mounting frame 200 to extend or retract the distance between two sides of the second mounting frame 200 .

[0036] Specifically, when the relevant staff are transporting items of different widths (such as pallets, cartons, etc.), first, the relevant staff controls the electric telescopic rod 700 according to the width required for the item transportation, so that the electric telescopic rod 700 pushes the two sides of the second mounting frame 200 to move closer to or away from each other, and then the first mounting frame 100 and the second mounting frame 200 are synchronously adjusted in position, so that the lengths of the transmission roller group 300, the adjustment roller group 400 and the guide roller group 500 change accordingly, that is, the relative distance between the sleeve 310 and the rotating shaft 320 changes, and after adjusting to the appropriate position, the electric telescopic rod 700 is closed. Since the electric telescopic rod 700 has its own limiting function, the width of the entire device will not continue to change after the adjustment is completed.

[0037] When the relevant staff needs to adjust the transmission distance, first, the relevant staff releases the lock on the up and down sliding of the adjusting roller group 400, and disassembles the quick release at the connection between the first mounting frame 100 and the second mounting frame 200, and then pulls the second mounting frame 200 to increase the relative distance between the transmission roller group 300 on the second mounting frame 200 and the transmission roller group 300 on the first mounting frame 100, thereby realizing a change in the transmission distance. At the same time, the relevant staff can move the position of the adjusting roller group 400 upwards so that the adjusting roller group 400 always maintains contact with the conveyor belt 600, and then locks the adjusting roller group 400 and the second mounting frame 200 to complete the adjustment of the transmission distance.

[0038] In one embodiment of the present invention, a slide rail seat 101 is provided on the first mounting frame 100 , and a sliding guide rail 201 is provided on the second mounting frame 200 . The sliding guide rail 201 is slidably provided on the slide rail seat 101 .

[0039] It should be noted that the slide rail seat 101 limits the sliding guide rail 201 from sliding along the length direction of the first mounting frame 100 to ensure the stability of the second mounting frame 200 when moving.

[0040] In one embodiment of the present invention, Figure 5 As shown, the two ends of the rotating shaft 320 and the sleeve 310 of the adjusting roller assembly 400 are respectively connected with connecting plates 401 . The connecting plates 401 are slidably arranged on the first mounting frame 100 or the second mounting frame 200 and are locked by a damping knob 402 .

[0041] It should be noted that a slide groove is provided on the first mounting frame 100 or the second mounting frame 200, and the damping knob 402 passes through the slide groove and is connected to the connecting plate 401. Relevant staff can limit the height of the adjustment roller group 400 by tightening the damping knob 402.

[0042] In addition, as a possible scenario, the limiting structure 340 includes a limiting groove 341 and a limiting bar 342 .

[0043] The inner wall of the sleeve 310 is provided with a limiting groove 341 along the length direction, and the outer wall of the rotating shaft 320 is provided with a limiting strip 342 along the length direction. When the sleeve 310 is sleeved on the rotating shaft 320, the limiting strip 342 is embedded in the limiting groove 341.

[0044] It should be noted that by embedding the limiting strip 342 in the limiting groove 341, the sleeve 310 and the rotating shaft 320 can rotate synchronously, so that the two rotating rollers 330 can rotate synchronously, so that the conveyor belt 600 on the two rotating rollers 330 can stably transmit items.

[0045] In order to further improve the flexibility of the present invention, the bottom of the first mounting frame 100 and the second mounting frame 200 are both provided with rollers for easy movement, and the rollers are universal wheels with a locking structure.

[0046] In one embodiment of the present invention, the first mounting frame 100 and the second mounting frame 200 each include two side panels disposed opposite to each other.

[0047] The mounting end of the electric telescopic rod 700 is fixedly arranged on one side plate of the second mounting frame 200 , and the telescopic end of the electric telescopic rod 700 is arranged on the other side plate of the second mounting frame 200 .

[0048] It should be noted that the control of the electric telescopic rod 700 by the relevant staff can push the two side panels on the second mounting frame 200 towards or away from each other. Since the first mounting frame 100 is connected to the second mounting frame 200 by sliding, the first mounting frame 100 can follow the second mounting frame 200 to move towards or away from each other synchronously, so that the two transmission roller groups 300, the two adjustment roller groups 400 and the guide roller group 500 can be adjusted synchronously to achieve changes in the transmission width.

[0049] In summary, according to the expandable conveying device of the embodiment of the present invention, the telescopic effect of the electric telescopic rod 700 can drive the length adjustment of the transmission roller group 300, the adjustment roller group 400 and the guide roller group 500, thereby realizing the change of the transmission width to meet the transmission requirements of different article widths, especially suitable for pallets, cartons and other articles with large size variations; by pulling the second mounting frame 200 and adjusting the height of the adjustment roller group 400, the transmission length can be changed to meet the requirements of different transmission distances.
