[0031] The utility model embodiment discloses a chip sweeping device of a permanent magnet chip conveyor.

[0032] Reference Figure 1-Figure 8 A permanent magnetic chip removal device comprises a frame 1 and a conveyor belt 2 arranged on the frame 1, and a protective cover 3 is arranged at the conveying end (chip outlet) of the conveyor belt 2. Figure 1 and Figure 3 As shown, the protective cover 3 covers the chip outlet, which can prevent chips from splashing, so that the chips can be swept out from the chip outlet in a concentrated manner. The frame 1 is rotatably provided with a cleaning drive shaft 15, and the frame 1 is provided with a driving mechanism for driving the cleaning drive shaft 15 to rotate. The driving mechanism serves as a power mechanism of the cleaning drive shaft 15 and also has the function of driving the conveyor belt 2 to rotate, that is, it also serves as a power mechanism of the conveyor belt 2.

[0033] Reference Figure 6-Figure 8 A cleaning drive bearing 18 is provided at the end of the cleaning drive shaft 15, and a scraper plate 16 is connected to the outer wall of the cleaning drive shaft 15. The scraper plate 16 is extended along the axial direction of the cleaning drive shaft 15, and the scraper plate 16 is located above the conveyor belt 2, and the bottom end of the scraper plate 16 contacts the conveyor belt 2. The rotation direction of the cleaning drive shaft 15 is opposite to the rotation direction of the conveyor belt 2, so that the rotation direction of the scraper plate 16 is opposite to the rotation direction of the conveyor belt 2 to ensure that the chips on the conveyor belt 2 can be swept out. The scraper plate 16 and the cleaning drive shaft 15 are both located in the protective cover 3. When the scraper plate 16 sweeps out the chips on the conveyor belt 2, the setting of the protective cover 3 can prevent the chips from splashing.

[0034] The cleaning drive shaft 15 is connected with a pressing plate 17, which is extended along the length direction of the cleaning drive shaft 15, and the width of the pressing plate 17 is smaller than the width of the scraper plate 16. The scraper plate 16 is located between the pressing plate 17 and the cleaning drive shaft 15. The arrangement of the pressing plate 17 can increase the strength of the connection between the scraper plate 16 and the cleaning drive shaft 15, further increase the strength of the scraper plate 16, and improve the service life of the scraper plate 16. Furthermore, the cleaning drive shaft 15, the scraper plate 16 and the pressing plate 17 are connected by screws, which can facilitate the removal and replacement of the scraper plate 16, thereby improving convenience.

[0035] Reference Figure 1 and Figure 4 The driving mechanism includes a reducer 5, which is installed above the frame 1. The output shaft of the reducer 5 is coaxially connected with the second driving sprocket 11. The frame 1 is provided with a driven sprocket 12 for driving the conveyor belt 2 to rotate. The second driving sprocket 11 is meshed with the driven sprocket 12 and is connected with a second transmission chain 13. The reducer 5 is started to drive the second driving sprocket 11 to rotate. The second driving sprocket 11 rotates so that the second driving sprocket 11 is meshed with the second transmission chain 13, thereby driving the second transmission chain 13 to rotate, and then driving the driven sprocket 12 to rotate, thereby achieving the purpose of driving the conveyor belt 2 to rotate.

[0036] The driving mechanism also includes a first driving sprocket 6 coaxially connected to the output shaft of the reducer 5, the frame 1 is provided with a tensioning sprocket 8, the tensioning sprocket 8 is connected to the frame 1 through a tensioning shaft 9, the tensioning shaft 9 is provided with a tensioning bearing 10, the tensioning sprocket 8 is rotatably connected to the frame 1, the first driving sprocket 6 and the tensioning sprocket 8 are meshedly connected with a first transmission chain 7, and the cleaning drive shaft 15 is coaxially connected with a cleaning drive sprocket 14. In this embodiment, the cleaning drive sprocket 14 is located at the lower left of the first transmission chain 7, and the cleaning drive sprocket 14 is not at the same height as the tensioning sprocket 8. Figure 4 As shown, when the first transmission chain 7 rotates, the cleaning transmission sprocket 14 rotates under the rotation of the first transmission chain 7, and the rotation direction of the cleaning transmission sprocket 14 is opposite to that of the tensioning sprocket 8.

[0037] In this embodiment, the reducer 5 rotates forward, the first driving sprocket 6, the first transmission chain 7, the tensioning sprocket 8, the second driving sprocket 11, the second transmission chain 13 and the driven sprocket 12 all rotate forward, that is, the rotation direction is the same, while the cleaning transmission sprocket 14 rotates in the reverse direction. When the cleaning transmission sprocket 14 rotates, it drives the cleaning drive shaft 15 to rotate, and then drives the scraper plate 16 to rotate. The rotation direction of the scraper plate 16 is opposite to the conveying direction of the conveyor belt 2, so as to sweep the chips on the conveyor belt 2 off the conveyor belt 2.

[0038] Reference Figure 5-Figure 6 The frame 1 is provided with an adjustment slot 19, which is inclined upward and is in a long strip shape. The tensioning shaft 9 is installed in the adjustment slot 19 by bolts and nuts. The setting of the adjustment slot 19 can adjust the position of the tensioning shaft 9, and then adjust the position of the tensioning sprocket 8, so as to adjust the tensioning force of the first transmission chain 7.

[0039] The adjusting groove 19 is a waist-shaped groove. The setting of the waist-shaped groove can make the tensioning shaft 9 fit more closely with the groove wall of the adjusting groove 19, thereby improving the fit and stability of the installation.

[0040] Reference Figure 1 The frame 1 is provided with a chain box 4, and the driving mechanism is located in the chain box 4. The arrangement of the chain box 4 can protect the driving mechanism.
