Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to tension rollers for belt conveyors. Background Technology

[0002] When a belt conveyor is in operation, the belt may become loose and elongated in some areas due to long-term operation of transporting goods, or the tension on the belt surface may be insufficient due to assembly factors. In this case, the belt may slip or the entire belt may shift, making it impossible to continue transporting goods. To solve this problem, a belt conveyor tensioning roller was designed. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to propose a tensioning roller for a belt conveyor, which enables tensioning of the belt, real-time monitoring of the belt tension for timely adjustment, and also achieves precise positioning of the belt.

[0004] The belt conveyor tension roller proposed in this utility model includes symmetrically arranged mounting plates. A geared motor is fixed to the side wall of each mounting plate. The output end of the geared motor passes through the mounting plate, and a mounting plate is provided at the output end of the geared motor. A torque sensor is fixed between the mounting plate and the output end of the geared motor. Two rollers are movably mounted between the mounting plates. Guide plates are symmetrically and movably mounted on the surface of each roller. An adjusting rod is threaded onto the surface of the mounting plate. A guide rod is movably mounted through the surface of the mounting plate, and both the guide rod and the adjusting rod are movably mounted to the guide plate on the same side.

[0005] Preferably, both ends of the roller body are provided with threaded ends, the surface of the threaded ends is fitted with bearings, and both ends of the roller body are threadedly fitted with end caps.

[0006] Preferably, the surface of the mounting plate has a threaded hole for threaded mounting of the adjusting rod, a fitting hole for movably fitting the guide rod, and symmetrical assembly holes for fitting the roller body.

[0007] Preferably, the surface of the guide disc is symmetrically provided with through holes for mounting the roller.

[0008] Preferably, a turntable is fixed to the end of the adjusting rod away from the mounting plate.

[0009] Preferably, a limiting plate is fixed to the end of the guide rod away from the mounting plate.

[0010] The beneficial effects of this utility model are: by setting two rollers and assembling them on the upper and lower sides of the belt of the belt conveyor, and by starting the reduction motor to drive the two rollers to rotate, the belt is guided to form an "S" shape in a local area, thereby achieving belt tensioning. A torque sensor is also provided to detect the belt tension in real time, ensuring that the belt receives appropriate tension.

[0011] It is also equipped with a guide plate to squeeze and position the belt from both sides to prevent the belt from shifting during assembly. When the belt tension is insufficient, the belt is prone to displacement. The guide plate can limit the belt. Attached Figure Description

[0017] Reference Figure 1-4The belt conveyor tension roller includes symmetrically arranged mounting plates 1. The specific structure of the mounting plates 1 can be adjusted according to the actual assembly situation. This tension roller can be assembled on the bottom or side wall of the belt conveyor housing. The mounting plate 1 structure provided in this embodiment is to fix the tension roller to the bottom of the belt conveyor housing, and leave a window at the corresponding position at the bottom of the housing to guide the belt. If it is installed on the side wall of the belt conveyor housing, the structure of the mounting plate 1 is a vertical plate. A reduction motor 2 is fixed on the side wall of the mounting plate 1. The output end of the reduction motor 2 passes through the mounting plate 1. The output end of the reduction motor 2 is provided with a mounting plate 3. A torque sensor 4 is fixed between the mounting plate 3 and the output end of the reduction motor 2. The torque sensor 4 of model MT-85 M / T / R can be used. Two roller bodies 5 are movably installed between the mounting plates 3. Guide plates 6 are symmetrically and movably installed on the surface of the roller bodies 5. Adjusting rods 7 are threaded on the surface of the mounting plates 3. Guide rods 8 are movably installed through the surface of the mounting plates 3. The guide rods 8 and the adjusting rods 7 are movably installed with the guide plates 6 on the same side.

[0018] Both ends of the roller body 5 are provided with threaded ends 51, and bearings 52 are fitted on the surface of the threaded ends 51. End caps 53 are threadedly installed on both ends of the roller body 5.

[0019] The surface of the mounting plate 3 has a threaded hole 31 for threaded installation of the adjusting rod 7, a fitting hole 32 for movable fitting of the guide rod 8, and symmetrical assembly holes 33 for fitting of the roller body 5. The bearing 52 of the roller body 5 is fitted into the assembly hole 33.

[0020] The surface of the guide plate 6 is symmetrically provided with through holes 61 for mounting the roller body 5.

[0021] A turntable 71 is fixed to the end of the adjusting rod 7 away from the mounting plate 3, making it easier to rotate the adjusting rod 7 by setting the turntable 71.

[0022] A limit plate 81 is fixed to the end of the guide rod 8 away from the mounting plate 3 to prevent the guide rod 8 from detaching.

[0023] During assembly, one of the mounting plates 1 is first fixed to the bottom of the belt conveyor. Then, two rollers 5 are fitted onto the side wall of the mounting plate 3 on that side. The rollers 5 pass through the guide plate 6 and the mounting plate 3 on that side. The bearing 52 at one end of the roller 5 is fitted into the mounting hole 33 of the mounting plate 3, and the end cap 53 is threaded on to achieve the positioning of the two rollers 5. The belt of the belt conveyor is guided through the space between the two rollers 5, so that the two rollers 5 are above and below the belt respectively. Next, another mounting plate 3 is fitted onto the side wall of the other end of the roller 5, and passes through the guide plate 6 on the other side. Finally, the mounting plate 1 on the other side is fixed to the bottom of the belt conveyor to complete the assembly. At this time, the belt is located between the two guide plates 6, and the upper and lower surfaces of the belt are in contact with the two rollers 5 respectively.

[0024] When using this device, first adjust the adjusting rods 7 on both sides according to the position of the belt being installed, so that the guide disc 6 just contacts the side wall of the belt. Then, make slight left and right adjustments to the position of the guide disc 6 according to the belt's assembly position on the conveyor. The guide disc 6 presses the belt, positioning it in a position suitable for the conveyor, thus assisting in belt positioning. Then, start the two reduction motors 2 on both sides to work synchronously. The reduction motors 2 drive the mounting disc 3 to rotate, which in turn drives the two rollers 5 to rotate around the center line of the mounting disc 3. The rollers 5 apply pressure to both sides of the belt from both above and below, causing the belt to rotate in an "S" shape in some areas. The system achieves overall belt tensioning. During the process, torque sensor 4 transmits torque data in real time. This torque data can directly reflect the magnitude of the tensioning force received on the belt surface. The gear motor 2 can be adjusted according to the torque data. If the torque is small, it means that the belt tension is small and further tensioning is required. If the torque is large, it means that the belt tension is large and the gear motor 2 needs to be reversed appropriately to reduce the torque and prevent the belt from breaking. Torque sensors 4 are set on both sides, and the gear motor 2 on one side can be adjusted separately according to the data to ensure that the output torque on both sides is the same, prevent local deformation of the belt, and better protect the belt.
