[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a device for cleaning oxide scale for processing tapered roller bearings, including a feed box 1 with an open top, the feed box 1 is used for placing the heat-treated tapered roller bearings, a conveying cylinder 2 is fixed on the side of the feed box 1, and a discharge port is provided at a position of the conveying cylinder 2 far from the feed box 1. An installation port communicating with the inner cavity of the conveying cylinder 2 is provided on the side of the feed box 1, and a screw conveyor mechanism 3 is installed in the installation port. One end of the screw conveyor mechanism 3 extends into the interior of the feed box 1, and the other end of the screw conveyor mechanism 3 extends to the discharge port. A driving component for driving the screw conveyor mechanism 3 to rotate is installed on the side of the feed box 1. The driving component includes a driving motor 4 installed on the side of the feed box 1. The output shaft of the driving motor 4 is fixedly connected to the end of the screw conveyor mechanism 3 through a coupling. By controlling the driving motor 4 to work, the screw conveyor mechanism 3 is driven to rotate, and the screw conveyor mechanism 3 conveys the bearing rollers in the feed box 1. During the movement of the bearing rollers, the bearing rollers rub against each other, so that the oxide scale on their outer surfaces falls off, facilitating the subsequent processing of the bearing rollers.

[0019] A plurality of slag discharge ports are provided in the lower part of the side of the conveying cylinder 2, and a collection frame 5 is fixed at a position of the side of the conveying cylinder 2 close to the slag discharge ports. After the oxide scale detaches from the outer surface of the bearing rollers, it falls to the outside through the slag discharge ports and is collected by the collection frame 5, preventing the detached oxide scale from being crushed after being squeezed for a long time and adhering to the outer surface of the tapered roller bearings, making it difficult to clean.

[0020] A feed hopper 6 is installed in the discharge port on the side of the conveying cylinder 2, and the feed hopper 6 is inclined. After the screw conveyor mechanism 3 conveys the bearing rollers to the end of the conveying cylinder 2, the bearing rollers are removed from the conveying cylinder 2 through the feed hopper 6 at the discharge port. A cleaning port communicating with the inner cavity of the collection frame 5 is provided on the side of the feed hopper 6, and a protective net 7 is installed in the cleaning port. A blowing component is installed on the side of the feed hopper 6, and the air outlet of the blowing component corresponds to the cleaning port. The blowing component includes a blower group 8 installed on the side of the feed hopper 6, and the air outlet of the blower group 8 corresponds to the cleaning port. When the bearing rollers move in the feed hopper 6, the working blower group 8 discharges air into the feed hopper 6, and the air acts on the bearing rollers to clean the debris adhering to their outer surfaces, and is also used for cleaning part of the oxide scale. Under the action of the air flow, the oxide scale enters the collection frame 5 through the protective net 7, and at the same time, the blower group 8 drives the air to move in the collection frame 5, facilitating the cleaning of the oxide scale collected in the collection frame 5.

[0021] A collection box 9 is provided on the lower side of the feeding box 1. A connecting pipe 12 is installed on the side of the collection box 9 and is communicated with its inner cavity. One end of the connecting pipe 12 away from the collection box 9 is fixed on the side of the collection frame 5 and is communicated with the inner cavity of the collection frame 5. The scale in the collection frame 5 enters the collection box 9 through the connecting pipe 12 under the action of air flow. An air outlet is provided on the side of the collection box 9, and a filter screen 10 is installed at the air outlet. The filter screen 10 is used for filtering the scale and scale debris in the air, preventing the debris from being carried out of the collection box 9 by the air flow. The scale accumulates in the collection box 9. A cleaning port communicated with its inner cavity is provided on the side of the collection box 9, and a box door 11 for shielding and sealing the cleaning port is provided on the side of the collection box 9. After the box door 11 is opened, the scale accumulated in the collection box 9 can be cleaned through the cleaning port.

[0022] An insertion port is provided on the side of the feeding box 1. A limiting plate 13 is slidably arranged in the insertion port, and the limiting plate 13 is located above the auger conveying mechanism 3. A positioning plate 14 for supporting and limiting the limiting plate 13 is fixed in the feeding box 1. By moving the limiting plate 13, the entering amount of the bearing rollers can be controlled, preventing too many bearing rollers from entering the conveying cylinder 2 and causing mutual extrusion deformation, which is convenient for the auger conveying mechanism 3 to convey the bearing rollers.

[0023] The driving motor 4, the blower set 8, etc. used in the present utility model are all common electronic components in the prior art. Their working modes and circuit structures are all well-known technologies, and the electronic components in the present utility model are controlled to work through an externally provided switch group or a PLC controller. This method is a common technical means for technicians and will not be elaborated here.

[0024] The parts not disclosed in the present utility model are all prior art, and their specific structures, materials and working principles will not be elaborated. Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
