[0028] Please refer to Figure 1 and Figure 2 , a degreasing device for fasteners, comprising an equipment rack 1, a feed hopper 2, a bobbin 3 and a motor 4.

[0029] The equipment rack 1 is provided with an oil collecting tank 1a. The top surface of the oil collecting tank 1a is provided with an oil outlet 1a1, and a valve 1a2 for controlling opening and closing is arranged on the oil outlet 1a1. Specifically, the equipment rack 1 may include a frame body and an oil collecting tank body. The frame body is welded by angle irons, and the top surface is a rectangular frame. The four edges of the top opening of the oil collecting tank body are welded and fixed to this rectangular frame.

[0030] The feed hopper 2 is fixedly connected to the first side position of the equipment rack 1. The top surface of the feed hopper 2 is open, which is the first feed port 2a, and the vertical side wall on the second side of the feed hopper 2 is provided with a first discharge port 2b. That is, the side wall on the first side of the feed hopper 2 is inclined, and the fasteners entering the feed hopper 2 from the first feed port 2a slide along this side wall to the first discharge port 2b.

[0031] The bobbin 3 is rotatably connected to the equipment rack 1. The rotational connection of the bobbin 3 to the equipment rack 1 can be completed by using support rollers. A plurality of mesh holes are distributed on the barrel wall (for the convenience of representation, these mesh holes are not shown in the drawings), that is, a plurality of mesh holes are evenly arranged and distributed on the barrel wall. The first end opening of the bobbin 3 is the second feed port 3a, which is connected to the first discharge port 2b of the feed hopper 2. Specifically, a material pipe 2b1 extending into the second feed port 3a may be provided on the first discharge port 2b. The second end opening of the bobbin 3 is the second discharge port 3b. Specifically, a guide plate 1b may be fixedly provided on the equipment rack 1, and the first side of the guide plate 1b is located below the second discharge port 3b.

[0032] Please refer to Figure 2 , Figure 3and Figure 4 In some embodiments, the degreasing device for fasteners further includes a shaft 5, and the bobbin 3 is rotatably connected to the equipment rack 1 through the shaft 5. The second end of the shaft 5 is fixedly connected to the second side position of the equipment rack 1. The first end of the shaft 5 passes through the bobbin 3 and is fixedly connected to the position of the first discharge port 2b of the feed hopper 2. Specifically, a horizontal first connecting block 2b2 may be fixedly connected to the first discharge port 2b, and the first end of the shaft 5 is fixedly connected to the first connecting block 2b2. Correspondingly, the fasteners can enter the bobbin 3 from the part of the first discharge port 2b below the first connecting block 2b2. The second end of the bobbin 3 rotates on the shaft 5. Specifically, a second connecting block 3b1 may be fixedly connected to the second discharge port 3b. Correspondingly, during the rotation of the bobbin 3, the fasteners can leave the bobbin 3 from the second discharge port 3b. A groove is provided on the second connecting block 3b1, and a bearing 3b2 is provided in the groove. The second end of the shaft 5 is stepped and is fitted to a shaft retaining ring to fix the bearing 3b2. The first end of the bobbin 3 rotates at the position of the first discharge port 2b of the feed hopper 2. Specifically, the second feed port 3a may be in the shape of a regular polygon, and universal balls 3a1 are fixed on each edge. By these universal balls 3a1 abutting against the outer wall of the feed pipe 2b1 of the first discharge port 2b, the rotational connection is completed.

[0033] In this way, the connection between the bobbin 3 and the equipment rack 1 is stable, and at the same time, the assembly is more convenient, and the disassembly is also more convenient, which is convenient for later maintenance and repair. Specifically, by disconnecting the connection between the shaft 5 and the equipment rack 1 and the feed hopper 2, the shaft 5 and the bobbin 3 can be moved along the shaft 5, so that the bobbin 3 and the feed hopper 2 are separated, and then the shaft 5 and the bobbin 3 can be removed together. By removing the shaft retaining ring on the shaft 5, the shaft 5 and the bobbin 3 can be disassembled.

[0034] Please refer to Figure 2 , the inner side of the barrel wall of the bobbin 3 also has a spiral blade 3c. According to the rotation direction of the spiral blade 3c, the rotation direction and rotation speed of the bobbin 3 are controlled, so that: the fasteners entering the bobbin 3 from the feed hopper 2 remain on the inner wall of the lower part of the bobbin 3. As the bobbin 3 rotates, these fasteners move from the second feed port 3a towards the second discharge port 3b under the action of the spiral blade 3c.

[0035] The lower part of the bobbin 3 is located in the oil sump 1a, so that: the above-mentioned "fasteners remain on the inner wall of the lower part of the bobbin 3" is equivalent to that the fasteners do not exceed the oil sump 1a. In this way, under the action of gravity and centrifugal force, the oil on the fasteners in the bobbin 3 falls out from the mesh holes and enters the oil sump 1a.

[0036] In some embodiments, the part of the bobbin 3 near the second end is frustum-shaped, and the diameter gradually increases along the direction from the second end to the first end.

[0037] In this way, when the fastener passes through this part of the bobbin 3, the oil is more likely to fall off. At the same time, after the diameter of the second end of the bobbin 3 is reduced, the setting between the bobbin 3 and the equipment rack 1 is more convenient.

[0038] The motor 4 drives the bobbin 3 to rotate. Specifically, a servo motor 4 with a reducer can be used and connected to the bobbin 3 through gear transmission 4a, belt drive, etc. In the attached drawing, a gear 4a is fixedly connected to the output shaft 5 of the motor 4, and a gear ring 3d meshing with the gear 4a is fixedly connected to the bobbin 3.

[0039] Please refer to Figure 2 and Figure 4 , in some embodiments, the motor 4 is located below the feed hopper 2. Specifically, on the first side position of the equipment rack 1, a mounting plate 1c is fixedly connected to the inner wall of the oil collecting tank 1a, the second side of the feed hopper 2 is supported by the mounting plate 1c, and the motor 4 is mounted on the bottom surface of the mounting plate 1c.

[0040] Please refer to Figure 5 , in some embodiments, the fastener degreasing device further includes an air pump 6. The shaft 5 is hollow and is provided with a plurality of downward jet nozzles 5a. The air pump 6 is connected to the second end of the shaft 5. Specifically, a hose can be used to connect the two (the hose is not shown in the attached drawing for convenience of representation).

[0041] In this way, through the air pump 6, the jet nozzles 5a jet air downward, so that the oil on the fastener is more likely to be separated and fall out from the mesh holes of the bobbin 3, and the surface of the fastener can also be dried.
