Disclosure of Invention

The invention aims to provide a conveyor belt cleaning device, which solves the technical problem that a scraper of the conveyor belt cleaning device in the prior art cannot always ensure a better cleaning effect.

In order to achieve the purpose, the basic scheme of the invention is as follows: conveyer belt cleaning device, including base and rotation direction and the opposite floating roll of conveyer belt rotation direction, the circumference equipartition of floating roll has a plurality of scraper units, the floating roll passes through the supporting mechanism fluctuation and connects on the base, the scraper unit includes the clearance scraper mechanism of scraper and clearance adhesion debris on the scraper, clearance scraper mechanism includes the sealed pipeline of fixed connection in floating roll circumference, the sealed pipeline is along the central direction opening of floating roll circumference towards keeping away from the floating roll, sealed pipeline opening part seals respectively and sliding connection has the driven slider that initiative slider and one side and scraper surface offset, along with the rotation of floating roll, the initiative slider at first receives the extrusion of conveyer belt to the central direction slip of floating roll, initiative slider, driven slider pass through the spring and are connected with the bottom of sealed pipeline.

The working principle of the basic scheme has the beneficial effects that: because a plurality of scraper units are uniformly distributed in the circumferential direction of the floating roller, when each scraper unit is contacted with the conveyor belt, the floating roller is pressed by the conveyor belt and vertically floats downwards through the supporting mechanism, so that the cleaning effect of the scraper on the conveyor belt is ensured; when the device is used for cleaning sundries with large adhesion on the conveying belt, the cleaning scraper mechanism can also clean the sundries adhered on the scraper except the scraper in each scraper unit, and the better cleaning effect of the scraper on the sundries on the conveying belt is always ensured.

When the scraper cleans the sundries on the conveyor belt, the sundries can enter a scraper unit formed by enclosing of the driving sliding block, the sealing pipeline and the scraper, and part of the sundries cleaned last time can be adhered to one side of the scraper close to the driven sliding block; when the floating roller rotates, a driving sliding block in one scraper unit is firstly extruded by the conveyor belt to slide towards the center direction of the floating roller, the volume in the sealed pipeline is reduced, and a driven sliding block slides towards the direction far away from the center of the floating roller; because the driven slide block is close to the scraper, and sundries are partially adhered to one end, close to the driven slide block, of the scraper, the driven slide block can separate the sundries adhered to the scraper from the scraper in the process of sliding towards the center direction far away from the floating roller, and the cleaning effect of the scraper on the sundries on the conveying belt is guaranteed.

The handle is rotated to control the screw rod to enter the L-shaped cavity pipeline and control the inner volume of the L-shaped cavity pipeline.

Furthermore, the scraper unit also comprises a recovery cylinder arranged on one side of the floating roller, and sundries can be poured into the recovery cylinder along with the rotation of the floating roller. The unrecoverable sundries enter the recovery cylinder to facilitate the uniform treatment of the sundries; and the recyclable sundries can enter the recycling cylinder to be recycled conveniently and uniformly.

Further, a plurality of heating plates are embedded on the floating roller close to the scraper unit, the heating plates are used for heating air in the sealing pipeline to dry sundries in the scraper unit, and the moisture of the sundries is reduced, so that the adhesion force of the sundries is favorably reduced, and the sundries are favorably discharged.

Further, the bottom of L type cavity pipeline is equipped with the elastic component of trompil, vertical branch passes through the elastic component and is connected with the bottom of L type cavity pipeline, the elastic component is the working of plastics of vertical trompil. The setting of working of plastics can further increase the stability of backup pad (floating roll) fluctuation, can further control the distance that backup pad (floating roll) floated from top to bottom through changing the working of plastics of co-altitude not.
