This tension sensor is equipped with a self-aligning bearing inside, which can be inserted with the roller shaft.

[0003] However, dust and impurities on the roller are easily accumulated on both sides of the roller, and will also be mixed with water stains. After a long period of accumulation, the sludge is easy to accumulate and form cakes. When rotating, it is easy to enter the bearing of the tension sensor. That is, the dirt is easily brought into the sensor directly with the smooth roller, causing blockage of the internal bearing of the tension sensor and affecting the operation of the sensor. In addition, it is not easy to add lubricating oil to the bearing for maintenance of this tension sensor after installation. Utility Model Content

[0016] like Figure 1 - Figure 2As shown, the utility model provides a tension sensor protection device, including a sensor body 1 and a roller 2, a bearing 3 is installed in the sensor body 1, a support plate 4 is fixedly installed on the sensor body 1, a scraper 5 is installed on the support plate 4, a groove 6 is opened on the roller 2, the scraper 5 is matched with the groove 6, a baffle 7 is fixedly connected to the roller 2 and located on the side of the groove 6, and a cover plate 8 is fixedly installed on the right side of the sensor body 1. When in use, the roller 2 is plugged and installed on the bearing 3 of the tension sensor body 1, and the dirt on the roller 2 can easily enter the bearing 3 part when rotating. The groove 6 and the baffle 7 can prevent sewage and sludge from entering with the roller 2. When there is too much dirt in the groove 6, the scraper 5 can scrape the dirt in the groove 6. Since the roller 2 is rotating during use, the scraper 5 can scrape the dirt in the groove 6. The bearing 3 part is further blocked by the cover plate 8, which can effectively protect the bearing 3 part of the tension sensor.
