Description

Technical Field

[0001] The present invention relates to the field of conveying equipment, and particularly to a synchronous belt tensioning device. Background Art

[0002] For a wire vertical core reel conveying system, generally, rollers and a synchronous belt are used in combination for driving. After the synchronous belt is used for a period of time, it will elongate. Since the tension of the synchronous belt cannot be adjusted, when the tension is too low, the synchronous belt will skip teeth during operation. At the moment of tooth skipping, the synchronous belt will break prematurely due to excessive tension. At the same time, the synchronous belt will rub against the roller track support, easily causing wear and breakage of the synchronous belt and obstruction of operation, resulting in production interruption. Summary of the Invention

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a synchronous belt tensioning device to solve the technical problem that the synchronous belt elongates after being used for a period of time in the prior art.

[0004] To achieve the above object and other related objects, the present invention provides a synchronous belt tensioning device, including a mounting plate, on which a plurality of rollers are provided, and a synchronous belt is provided on the rollers, characterized in that:

[0005] A bottom plate, the bottom plate is arranged on the mounting plate, and a driver is provided on the bottom plate;

[0006] An adjuster, the adjuster is located between any two adjacent rollers, one end of the adjuster is a fixed end, and the other end is a movable end. The fixed end is arranged on the bottom plate, and the movable end is connected to the movable end of the driver. The driver is used to make the movable end approach or move away from the synchronous belt.

[0007] The advantage of adopting the above technical solution is that by providing an adjuster and connecting the movable end of one end thereof to the movable end of the driver, the driver can drive the movable end of the adjuster to approach or move away from the synchronous belt. In this way, when the synchronous belt elongates and causes insufficient tension, the position of the adjuster can be adjusted by the driver, thereby effectively adjusting the tension of the synchronous belt and avoiding tooth skipping and breakage.

[0008] Optionally, the bottom plate is arranged at the edge of the mounting plate, and the bottom plate is perpendicular to the mounting plate.

[0012] Optionally, the driver includes a screw rod and a hinge part. A screw hole is provided on the bottom plate. The screw rod is threadedly arranged in the screw hole. The hinge part is arranged at the end of the screw rod close to the adjuster. A connecting rod is also provided in the middle of the two support plates, and the hinge part is hinged to the connecting rod.

[0016] Optionally, a guard plate is further provided on the mounting plate. The guard plate is arranged opposite to the bottom plate, perpendicular to the mounting plate, and on the same side of the mounting plate as the bottom plate.

[0017] As described above, a synchronous belt tensioning device of the present invention has the following beneficial effects: By providing an adjuster and connecting the movable end at one end thereof to the movable end of the driver, the driver can drive the movable end of the adjuster to approach or move away from the synchronous belt. In this way, when the synchronous belt is stretched and the tension is insufficient, the position of the adjuster can be adjusted by the driver, thereby effectively adjusting the tension of the synchronous belt and avoiding the occurrence of tooth skipping and breakage.

[0028] Please see Figure 1 As shown, the present invention provides a synchronous belt tensioning device, including a mounting plate 1. A plurality of rollers 101 are provided on the mounting plate 1, and a synchronous belt 102 is provided on the rollers 101. It is characterized in that:

[0029] A bottom plate 2, the bottom plate 2 is arranged on the mounting plate 1, and a driver 3 is provided on the bottom plate 2;

[0030] An adjuster 4, the adjuster 4 is located between any two adjacent rollers 101. One end of the adjuster 4 is a fixed end, and the other end is a movable end. The fixed end is arranged on the bottom plate 2, and the movable end is connected to the movable end of the driver 3. The driver is used to make the movable end approach or move away from the synchronous belt 102.

[0031] It should also be noted that by setting the adjuster 4 and connecting the movable end of one end thereof to the movable end of the driver 3, the driver 3 can drive the movable end of the adjuster 4 to approach or move away from the synchronous belt 102. In this way, when the synchronous belt is stretched and the tension is insufficient, the position of the adjuster 4 can be adjusted by the driver 3, so as to effectively adjust the tension of the synchronous belt and avoid the occurrence of tooth skipping and breakage.

[0032] Exemplarily, the bottom plate 2 is arranged at the edge of the mounting plate 1, and the bottom plate 2 is perpendicular to the mounting plate 1.

[0033] It should also be noted that as the support structure of the driver 3 and the adjuster 4, the vertical installation of the bottom plate 2 can ensure that these components are stably and firmly fixed on the mounting plate 1. This vertical arrangement provides the necessary rigidity and stability, preventing the driver 3 and the adjuster 4 from shifting or loosening during operation.

[0034] Exemplarily, a roller is arranged at the end of the movable end of the adjuster 4.

[0035] It should also be noted that the setting of the roller reduces the direct contact between the movable end of the adjuster 4 and the synchronous belt 102 or other components, thereby reducing the friction and wear. This helps to extend the service life of the synchronous belt and the adjuster 4. The roller enables the movable end of the adjuster 4 to approach or move away from the synchronous belt 102 more smoothly. During the adjustment process, the roller can roll rather than slide, thereby reducing the force and time required for adjustment.

[0036] Exemplarily, a hinge seat is arranged on the bottom plate 2, the fixed end of the adjuster 4 is hinged to the hinge seat, and the axis of the rotation shaft of the adjuster 4 is parallel to the axis of the rotation shaft of the roller 101.

[0037] It should also be noted that through the setting of the hinge seat, the adjuster 4 can rotate flexibly within a certain range. This flexibility enables the movable end of the adjuster 4 to more easily approach or move away from the synchronous belt 102, so as to achieve precise adjustment of the tension of the synchronous belt. The axis of the rotation shaft of the adjuster 4 is parallel to the axis of the rotation shaft of the roller 101, which can ensure that during the process of adjusting the tension of the synchronous belt, the synchronous belt will not generate unnecessary offset or distortion due to the movement of the adjuster. This helps to maintain the stable operation of the synchronous belt and reduce the vibration and impact generated by the adjustment.

[0038] Exemplarily, the adjuster 4 includes two support plates. The support plates are strip-shaped plates. The two ends of the two support plates are respectively connected by a connecting shaft. The roller is arranged on one of the connecting shafts, and the hinge seat is arranged on the other connecting shaft.

[0039] It should also be noted that the two support plates, as the main structure of the adjuster 4, are connected by a connecting shaft to form a movable frame. This structure provides stable support for the rollers and the hinge seats, enabling the adjuster 4 to flexibly adjust the tension of the synchronous belt when needed. The rollers are arranged on one of the connecting shafts and are used to directly contact the synchronous belt, reducing friction and wear through rolling, and at the same time realizing the tension adjustment of the synchronous belt. The hinge seats are arranged on the other connecting shaft and are hinged with the hinge seats on the bottom plate 2, allowing the adjuster 4 to rotate within a certain range, thereby realizing the precise adjustment of the tension of the synchronous belt.

[0040] Exemplarily, the driver 3 includes a screw rod and a hinge portion. A threaded hole is provided on the bottom plate 2, the screw rod is threadedly arranged in the threaded hole, the hinge portion is arranged at the end of the screw rod close to the adjuster 4, and a connecting rod is further provided in the middle of the two support plates, and the hinge portion is hinged with the connecting rod.

[0041] It should also be noted that the threaded fit between the screw rod and the threaded hole allows the screw rod to perform precise linear movement on the bottom plate 2. When the screw rod rotates, it moves up and down along the threaded hole, thereby driving the hinge portion and the connecting rod to perform linear displacement. The hinged connection between the hinge portion and the connecting rod allows the adjuster 4 to perform corresponding rotational adjustment according to the movement of the screw rod. This design enables the adjuster 4 to flexibly change the distance between it and the synchronous belt 102, realizing precise tension adjustment.

[0042] Exemplarily, a protective layer is further provided on the outer wall of the roller.

[0043] Exemplarily, the protective layer is rubber.

[0044] It should also be noted that the rubber protective layer can cover the outer wall of the roller, effectively isolating the erosion of dust, moisture, corrosive substances, etc. in the external environment on the metal matrix of the roller, thereby protecting the surface of the roller from damage. The rubber material has good wear resistance and can significantly extend the service life of the roller. When the roller interacts with the synchronous belt or other contact surfaces, the rubber protective layer can reduce friction and wear and keep the roller in good operating condition.

[0045] Exemplarily, threads are provided at both ends of the connecting shaft, connecting holes are provided at both ends of the support plate, both ends of the connecting shaft respectively extend out from the corresponding connecting holes, and nuts are provided at the extending ends of the connecting shaft.

[0046] It should also be noted that by setting threads at both ends of the connecting shaft and corresponding connecting holes at both ends of the support plate, the connecting shaft and the support plate can be conveniently connected. When it is necessary to disassemble or replace components, simply loosen the nuts to easily separate the connecting shaft and the support plate without the need to use complex tools or perform destructive disassembly. Since threads are provided at both ends of the connecting shaft and can be tightened by nuts, the distance between the two support plates can be conveniently adjusted. This adjustment function may be very important in certain applications. For example, when it is necessary to change the overall length of the adjuster 4 to adapt to different installation environments or usage requirements.

[0047] Exemplarily, a guard plate is further provided on the mounting plate 1. The guard plate is disposed opposite to the bottom plate 2, perpendicular to the mounting plate 1, and the guard plate and the bottom plate 2 are on the same side of the mounting plate 1.

[0048] It should also be noted that the presence of the guard plate provides an additional protective layer for the key components of the device, such as the bottom plate 2 and the components thereon. In complex or harsh working environments, the guard plate can effectively prevent sundries, dust, moisture, etc. from entering the interior of the device, reduce the risk of component damage, and protect the operating environment of the roller 101 and the synchronous belt 102.

[0049] In summary, by adopting a synchronous belt tensioning device of the present invention, an adjuster 4 is provided, and the movable end of one end thereof is connected to the movable end of the driver 3. The driver 3 can drive the movable end of the adjuster 4 to approach or move away from the synchronous belt 102. In this way, when the synchronous belt is stretched and the tension is insufficient, the position of the adjuster 4 can be adjusted by the driver 3, thereby effectively adjusting the tension of the synchronous belt and avoiding tooth skipping and breakage.
