Technical Field

[0001] The utility model relates to the field of tension belt conveyors, in particular to a tension regulating device for a tension belt conveyor. Background Art

[0002] The pull-out belt conveyor is also called a long-distance belt conveyor. It is a device used in the sorting of the logistics industry to transport logistics packages. The pull-out belt conveyor is prone to loosening after long-term use, which affects the transportation of logistics packages. Currently, the tensioning wheel is adjusted manually, and the adjustment efficiency is low. Therefore, in order to solve the shortcomings of the existing technology, a tension adjustment device for the pull-out belt conveyor with a simple structure needs to be designed. Utility Model Content

[0005] As a further improvement, an extension rod is provided on the outer side of the second rack, and the second tensioning wheel is rotatably disposed on the outer end of the extension rod.

[0006] As a further improvement, a pay-off wheel 1 is provided at the rear end of the driving wheel 1, a guide wheel 1 is provided between the pay-off wheel 1 and the weight 1, a pay-off wheel 2 is provided at the rear end of the driving wheel 2, and a guide wheel 2 is provided between the pay-off wheel 2 and the weight 2.

[0008] As a further improvement, a fixing base is provided at the lower end of the fixing sleeve and the fixing rod.

[0009] Compared with the prior art, the tensioning adjustment device of the utility model for the pull-length belt conveyor has the following beneficial effects:

[0010] When the belt is loose, the weight one drives the driving wheel one to rotate counterclockwise, and the weight two drives the driving wheel two to rotate clockwise, thereby driving the gear one to rotate counterclockwise and the gear two to rotate clockwise, driving the rack one to rise and drive the tensioning wheel one to move upward, driving the rack two to move downward and drive the tensioning wheel two to move downward. The structure is simple, and the linkage assembly cooperates with the gravity of the weight to realize automatic tensioning of the belt by the tensioning wheel one and the tensioning wheel two. The traditional tensioning method using the elastic force of the spring will partially fail after long-term use. In comparison, this structure is maintenance-free. Moreover, due to the long length of the long-distance belt conveyor and the large amount of belt slack, two sets of tensioning wheels two are used in conjunction with the middle tensioning wheel one to greatly increase the belt tensioning amount and achieve better effect.

[0018] A tensioning and adjusting device for a tensioning belt conveyor, comprising: a tensioning wheel 11, a tensioning wheel 2 12, a rack 1 21, a rack 22, a gear 1 31, a gear 2 32, a driving wheel 1 41, a driving wheel 2 42, a weight 1 51 and a weight 2 52, wherein the tensioning wheel 2 12 is symmetrically arranged on both sides of the tensioning wheel 1 11, the rack 1 21 is connected to the rear end of the tensioning wheel 1 11, and the rack 2 22 is arranged on both sides of the rack 1 21 and connected to the rear end of the tensioning wheel 2 12 The gear 1 31 is meshedly connected to the rack 1 21 and the rack 2 22 on the left side, the gear 2 32 is meshedly connected to the rack 1 21 and the rack 2 22 on the right side, the driving wheel 1 41 is connected to the gear 1 31, the driving wheel 2 42 is connected to the gear 2 32 and is meshedly connected to the driving wheel 1 41, the weight 1 51 is connected to the driving wheel 1 41, the weight 2 52 is connected to the driving wheel 2 42, and the tensioning wheel 1 11 and the tensioning wheel 2 12 are connected with a belt 6.

[0019] like Figure 1-2 As shown, the use principle of the present invention is as follows: according to the weight 1 51 and the weight 2 52 on the left and right sides, when the belt 6 is loose, the weight 1 51 drives the driving wheel 1 41 to rotate counterclockwise, and the weight 2 52 drives the driving wheel 2 42 to rotate clockwise, thereby driving the gear 1 31 to rotate counterclockwise, and the gear 2 32 to rotate clockwise, driving the rack 1 21 to rise and drive the tensioning wheel 11 to move upward, driving the rack 22 to descend and drive the tensioning wheel 2 11 to move downward.
