Description

Technical Field

[0001] This utility model relates to the field of transmission, and more specifically, to a device and transmission belt device for automatically adjusting the tension of a transmission belt in an industrial variable load equipment. Background Technology

[0002] In belt-driven equipment, belt tension often needs adjustment due to belt aging or load changes. In industrial production, the tension of transmission belts in large equipment is typically achieved by adjusting the distance between the motor and the equipment's sliding groove. However, this method often requires stopping production in large equipment, is time-consuming, and can only fix one tension level. Therefore, there is an urgent need for a device that can adjust tension online. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a device for automatically adjusting the tension of a transmission belt in an industrial variable load device. This device aims to improve at least one of the problems mentioned in the background art.

[0004] A device for automatically adjusting the tension of a transmission belt in an industrial variable load equipment includes a tension sensor detection roller, a tension sensor that is attached to the tension sensor detection roller, a transmission gear, a driven gear, a rotating support, and a connecting mounting plate. The tension sensor, the rotating support, and the driven gear are all mounted on the connecting mounting plate, and the transmission gear and the driven gear mesh with each other.

[0005] Optionally, the rotating lug includes an upper lug, a lower lug, and a shaft, with the shaft connected to the lower lug and a hole provided on the upper lug through which the shaft passes.

[0006] Optionally, the passive tooth is a fan-shaped tooth, and the toothless end of the passive tooth is connected to the upper ear.

[0007] This utility model also provides an automatic adjustment transmission belt device for industrial variable load equipment.

[0008] An automatic adjustment transmission belt device for industrial variable load equipment includes a driven pulley, a drive pulley, and a transmission V-belt assembly. It also includes the aforementioned device for automatically adjusting the tension of the transmission belt and a servo motor. The transmission V-belt assembly is pressed onto a tension sensor detection roller, and the transmission gear is connected to the servo motor.

[0009] Optionally, a protective shield may also be included.

[0010] Optionally, the protective cover is provided with a transparent protective plate.

[0011] Optionally, the transparent protective panel is an acrylic protective panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention is applicable to equipment with large load variations and heavy loads in each production cycle, such as industrial kneaders, where the load can vary from 300Nm to 10000Nm within 5-8 hours. In this invention, the transmission V-belt is controlled by a tension sensor. The tension signal of the V-belt is transmitted from the sensor's output line to the signal controller in the control box. The signal controller then precisely controls the servo motor to adjust the tension of the V-belt accordingly (it can be loosened or tightened). If the servo motor has adjusted the rotation angle of the driven gear to its maximum, an alarm is activated to remind personnel to replace the transmission V-belt assembly. The tension sensor has a timing function; for example, it sends a maintenance signal when the equipment reaches its scheduled maintenance period. The transparent protective cover allows inspectors to easily observe the equipment's operating status. This tensioning device can also be used on chain drive equipment. Attached Figure Description

[0023] Example 1

[0024] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the device for automatically adjusting the tension of the transmission belt in an industrial variable load equipment according to this utility model.

[0025] A device for automatically adjusting the tension of a transmission belt in an industrial variable load equipment includes a tension sensor detection roller 1, a tension sensor that is attached to the tension sensor detection roller 1, a transmission gear 4, a driven gear 5, a rotating support 6, and a connecting mounting plate 7.
