Technical Field

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

[0002] A conveyor is a material handling machine that continuously transports materials along a certain route. The conveyor can carry out horizontal, inclined and vertical transportation, and can also form a spatial transportation route. According to the operation mode, it can be divided into: belt conveyor, screw conveyor, bucket elevator, roller conveyor, metering conveyor, plate chain conveyor, mesh belt conveyor and chain conveyor.

[0003] The existing conveyor tensioning device installs a screw on one side, and rotates the screw to drive the roller on one side to move on the conveyor side plate to tighten the conveyor belt and achieve tension. However, when tensioning, since the roller on one side drives the conveyor belt to be tightened and straightened, a gap may appear between the conveyor belt and the auxiliary roller in the middle, resulting in the problem that the conveyor belt cannot fit with the auxiliary roller. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a conveyor belt tensioning device, which solves the problem that when the conveyor belt is tensioned, a roller on one side drives the conveyor belt to be tightened and straightened, which may cause a gap between the conveyor belt and the auxiliary roller in the middle, resulting in the conveyor belt being unable to fit with the auxiliary roller.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a conveyor belt tensioning device comprises a conveyor, and a tensioning structure is arranged at one end of the conveyor.

[0006] The tensioning structure includes a bearing seat and a sliding plate, the upper and lower ends of the bearing seat are slidably sleeved with sliding rails, one end of the bearing seat is provided with a mounting ring, the inner cavity of the mounting ring is rotatably sleeved with a screw rod, and one end of the screw rod is integrally extended with an extrusion head, the surface of the screw rod is threadedly sleeved with a mounting plate, the top of the sliding plate is symmetrically fixedly connected with a spring, and the top of the spring is fixedly connected with a mounting bracket, the bottom of the sliding plate is symmetrically fixedly connected with a connecting plate, the connecting plate is rotatably sleeved with a rotating shaft, and both ends of the sliding plate are fixedly connected with moving plates, and the inner cavity of the moving plate is integrally extended with an inclined extrusion end.

[0012] Beneficial Effects

[0013] The utility model provides a conveyor belt tensioning device. Compared with the prior art, it has the following beneficial effects:

[0014] 1. The conveyor belt tensioning device drives the bearing seat to move and pulls one side of the installed main roller conveyor belt to be straightened by rotating the screw rod. At the same time, the extrusion head will squeeze the inclined extrusion end, and drive the sliding plate to move downward through the moving plate, so that the rotating shaft is against the conveyor belt below. By tensioning one side and the bottom at the same time, the upper conveyor belt will fit closely on the auxiliary roller, avoiding gaps and achieving better tensioning effect.

[0015] 2. The conveyor belt tensioning device will leave the inner cavity of the inclined extrusion end and the moving plate through the extrusion head at one end of the screw rod, so that after the inclined extrusion end loses the extrusion force, the rotating shaft and the sliding plate will be driven to automatically reset under the elastic force of the spring.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 3-4 The tensioning structure 2 includes a bearing seat 23 and a sliding plate 22, and then the main roller shaft on one side is fixedly sleeved in the bearing seat 23, and one end of the sliding plate 22 is slidably sleeved in the slide groove, and the upper and lower ends of the bearing seat 23 are slidably sleeved with a slide rail 21, and one end of the bearing seat 23 is provided with a mounting ring 24, and the inner cavity of the mounting ring 24 is rotatably sleeved with a screw rod 25, and one end of the screw rod 25 is integrally extended with an extrusion head 27, and the extrusion head 27 is arc-shaped, one end of the screw rod 25 is located in the inner cavity of the extrusion head 27, and the surface of the screw rod 25 is threadedly sleeved with a mounting plate 26, and the top of the sliding plate 22 is symmetrically fixedly connected with a spring 211, and the top of the spring 211 is fixedly connected with a mounting bracket 29, and the mounting bracket 29 is fixedly installed on the inner side of the conveyor 1, that is, it is installed above the slide groove opened on the side plate.

[0024] The bottom of the sliding plate 22 is symmetrically fixedly connected with a connecting plate 28, and the connecting plate 28 is rotatably sleeved with a rotating shaft 210, and the two ends of the sliding plate 22 are fixedly connected with a moving plate 212, the inner cavity diameters of the extrusion head 27 and the moving plate 212 are consistent with each other, and the inner cavity of the moving plate 212 is integrally extended with an inclined extrusion end 214, and the extrusion head 27 and the inclined extrusion end 214 are rubber-abutted against each other, and the slide rail 21 and the mounting plate 26 are fixedly installed on the side of the conveyor 1, that is, installed on the side plate.

[0025] During use, when tensioning is performed, the nut 213 on both sides is clamped by a tool, and the nut 213 is rotated to make the screw rod 25 threadedly rotate on the mounting plate 26, thereby driving the bearing seat 23 to move outward on the slide rail 21 by rotating the connected mounting ring 24, so that the main roller in the bearing seat 23 pulls the conveyor belt on the surface to straighten it, thereby achieving tensioning. At the same time, when the screw rod 25 moves to one side through thread rotation, it will drive the extrusion head 27 at one end to enter the inner cavity of the moving plate 212 and squeeze the inclined extrusion end 214, so that the inclined extrusion end 214 will move downward, and drive the sliding plate 22 to move downward in the slide groove at the beginning of the conveyor 1, so that the rotating shaft 210 is against the conveyor belt below, driving the conveyor belt part below to be squeezed downward, so that the upper conveyor belt will be tightly fitted on the auxiliary roller, avoiding gaps and making the tensioning effect better.

[0026] In addition, when it is necessary to loosen, the screw rod 25 is reversed according to the above steps to reset the bearing seat 23, thereby loosening the conveyor belt. Next, the extrusion head 27 at one end of the screw rod 25 will leave the inner cavity of the inclined extrusion end 214 and the movable plate 212. In this way, after the inclined extrusion end 214 loses the extrusion force, it will drive the rotating shaft 210 and the sliding plate 22 to reset under the elastic force of the spring 211, thereby loosening the tension on the conveyor belt below. In this way, when the conveyor belt is loosened, it is also convenient for maintenance.
