DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] The embodiment of the present application provides a tensioning device for a chain conveyor, which can solve the problem of different lengths of chains required for different conveying strokes in the related art.

[0030] Please refer to Figures 1 to 5 A tensioning device for a chain conveyor comprises two sprockets 1, an adjusting wheel 2, and a horizontal moving structure 4. The adjusting wheel 2 and the two sprockets 1 are located on the same plane, and the adjusting wheel 2 and the two sprockets 1 are wound with a chain 3. The horizontal moving structure 4 comprises a sleeve 41, a moving column 42, and a hinge 43. The sleeve 41 is connected with the adjusting wheel 2, the moving column 42 is located in the sleeve 41, and the hinge 43 is connected with the moving column 42. The sleeve 41 is provided with a sliding groove 44, and the moving column 42 is provided with a sliding block 45 which is slidingly connected in the sliding groove 44.

[0031] In the embodiment, the two sprockets 1 and the adjusting wheel 2 are located on the same plane. The distance between the two sprockets 1 is confirmed by a conveying stroke, and then the position of the adjusting wheel 2 is adjusted to control the distance between the two sprockets 1 and the adjusting wheel 2, so that the chain 3 is wound around the adjusting wheel 2 and the two sprockets 1, and the chain appears to be loose.

[0032] When the adjusting wheel 2 rotates, the adjusting wheel 2 drives the sleeve 41, and through the sliding groove 44 and the sliding block 45, the sleeve 41 drives the moving column 42 to rotate on the hinge 43, as shown in Figure 3 In order to make the adjusting wheel 2 suitable for different widths of the frame, the position of the moving column 42 in the sleeve 41 needs to be adjusted.

[0033] Further, in the embodiment, the horizontal moving structure 4 further comprises a rotating cover 46, a first screw rod 47, a screw hole 48, an expansion groove 49, an expansion block 410, a synchronous ring 411, a matching ring 412, the rotating cover 46 is rotationally connected in the adjusting wheel 2, the rotating cover 46 is connected with the first screw rod 47, the screw hole 48 is arranged on the moving column 42, the first screw rod 47 is matched with the screw hole 48, the expansion groove 49 is arranged on the rotating cover 46, the expansion block 410 is connected on the first screw rod 47, the expansion block 410 is slidingly connected on the expansion groove 49, the rotating cover 46 is slidingly connected, the synchronous ring 411 is connected with the rotating cover 46, the matching ring 412 is connected with the adjusting wheel 2, the synchronous ring 411 can be inserted into the matching ring 412;

[0034] When the distance between the adjusting wheel 2 and the articulated member 43 needs to be adjusted, the rotating cover 46 is pressed, so that the synchronous ring 411 is separated from the matching block 412, and the state of being not matched is adjusted, and the operation of the chain 3 is stopped, at this time, the adjusting wheel 2 cannot rotate due to the action of the chain 3, the rotating cover 46 and the first screw rod 47 can rotate on the adjusting wheel 2, because the adjusting wheel 2 cannot rotate, the sleeve 41, the moving column 42 and the articulated member 43 cannot rotate, when the first screw rod 47 rotates, under the action of the screw thread, the moving column 42 is expanded or contracted in the sleeve 41, the distance between the adjusting wheel 2 and the articulated member 43 is controlled by rotating the rotating cover 46, and then the distance between the adjusting wheel 2 and the articulated member 43 is controlled;

[0035] After the adjustment is completed, the rotating cover 46 is pulled outward, so that the synchronous ring 411 is embedded with the matching block 412, when the adjusting wheel 2 rotates, the rotating cover 46 rotates synchronously, and the first screw rod 47 rotates synchronously with the sleeve 41 and the moving column 42, so as to avoid that the first screw rod 47 rotates due to the rotation of the adjusting wheel 2, and then the distance between the adjusting wheel 2 and the articulated member 43 is adjusted;

[0036] It should be pointed out that the expansion block 410 and the expansion groove 49 are as shown in Figure 3 , and the expansion block 410 is located in the expansion groove 49, under the self-locking property of the first screw rod 47, the function that the rotating cover 46 moves on the first screw rod 47 and the rotating cover 46 can drive the first screw rod 47 to rotate is realized.

[0037] Further, in the embodiment, two support structures 5 are further included, the support structure 5 comprises a support rod 51, a sliding block 52, a second screw rod 53, two meshing gears 55, one end of the support rod 51 is connected with the articulated member 43, the other end of the support rod 51 is hinged with the sliding block 52, the second screw rod 53 is rotationally connected on the frame 54, the second screw rod 53 passes through the sliding block 52, and the screw rod is matched with the sliding block 52, the two meshing gears 55 are connected on the second screw rod 53;

[0038] As Figure 2As shown, the frame 54 is rotatably connected with two second screw rods 53, the meshing gears 55 on the two different second screw rods 53 are meshed with each other, so that when one of the second screw rods 53 is driven by the motor or manually, the other second screw rod 53 can be simultaneously driven, so that the two second screw rods 53 are synchronously rotated, and the two sliding blocks 52 are conveniently driven to approach or move away from each other. In the process that the two sliding blocks 52 approach each other, the two supporting rods 51 will push the adjusting wheel 2 and the horizontal moving structure 4 upwards, so as to raise the height of the adjusting wheel 2. In the process that the two sliding blocks 52 move away from each other, the two supporting rods 51 will pull the adjusting wheel 2 and the horizontal moving structure 4 downwards, so as to lower the height of the adjusting wheel 2. In conclusion, the driving of one of the second screw rods 53 controls the height of the adjusting wheel 2, and further controls the distance between the adjusting wheel 2 and the two chain wheels 1.
