Detailed Implementation

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] Example:

[0026] like Figures 1-4 As shown, a knife sharpening machine includes a machine body 10, a sharpening device 20, a cleaning mechanism, and a waste chip bin 11. The sharpening device 20 is mounted on the top of the machine body 10 via a track. The waste chip bin 11 is located at the bottom of one side of the machine body 10 and communicates with the bottom inner side of the machine body 10. The cleaning mechanism includes a first support shaft 31, a second support shaft 32, a first pulley 33, a second pulley 34, and a scraper. The first support shaft 31 and the second support shaft 32 are respectively rotatably mounted on opposite sides of the machine body 10 via bearings. The first pulley 33 includes two pulleys, which are respectively located at both ends of the first support shaft 31 near the side wall of the machine body 10. The second pulley 34 includes two pulleys, which are respectively located at both ends of the second support shaft 32 near the side wall of the machine body 10. The first pulley 33 and the second pulley 34 on the same side are connected to the first support shaft 32. A drive belt 35 is provided between each pulley 34; the scraping component includes a connecting block 41 and a scraper 42 located at the bottom of the connecting block 41. Connecting grooves 43 matching the width of the drive belt 35 are provided on both sides of the top of the connecting block 41. The connecting grooves 43 pass through both sides corresponding to the moving direction of the drive belt 35. A buckle plate 44 is provided on the top of the connecting groove 43. A first connecting hole 45 is provided on the buckle plate 44. A second connecting hole is provided on the drive belt 35. A screw hole is provided at the bottom of the connecting groove 43. A bolt is provided on the buckle plate 44 that passes through the first connecting hole 45 and the second connecting hole and connects to the screw hole. The connecting block 41 is connected to the drive belt 35 by bolt connection, which is stable and easy to disassemble and assemble; one end of the first support shaft 31 extends to the outside of the machine body 10 and is connected to a handle 36.

[0027] The working principle of the above technical solution is as follows:

[0028] Before cleaning, move the scraper to the side of the machine body 10 away from the waste bin 11. When it is necessary to clean the debris inside the bottom of the machine body 10, the operator only needs to turn the handle 36 outside the machine body 10, turn the first support shaft 31, drive the first pulley 33 to rotate, and drive the second pulley 34 and the second support shaft 32 to rotate through the transmission belt 35. The scraper on the bottom side of the transmission belt 35 moves to the side of the waste bin 11, scraping the debris inside the bottom of the machine body 10 during the movement until the scraper 42 moves to the waste bin 11, and collects the debris into the waste bin 11. After cleaning, turn the handle 36 in the opposite direction to restore the position of the scraper. The scraper only moves on the bottom side of the first pulley 33 and the second pulley 34.

[0029] In another embodiment, such as Figure 4 As shown, the two sides of the scraper 42 are bent toward the side of the machine body 10 corresponding to the waste bin 11, and are set at an obtuse angle with the middle of the scraper 42. The two side edges of the scraper 42 abut against the inner side wall of the machine body 10, and the bottom side of the scraper 42 abuts against the inner bottom wall of the machine body 10, so as to prevent debris from leaking out from the gap between the scraper 42 and the machine body 10. The scraper 42 can be made of rubber.

[0030] The scraper 42 is bent on both sides, which helps the debris to concentrate in the middle of the scraper 42.

[0031] In another embodiment, such as Figure 2-3 As shown, the bottom of the machine body 10 is provided with a support platform 12 on both sides parallel to the transmission belt 35. The two sides of the connecting block 41 are movably connected to the support platform 12. Optionally, rollers 46 are provided at the bottom of both sides of the connecting block 41. After the support platform 12 is provided, the two sides of the tube plate are changed to abut against the side wall of the support platform 12.

[0032] The support platform 12 supports the connecting block 41, reduces the weight of the transmission belt 35, and ensures the smooth operation of the transmission belt 35. The support platform 12 is connected by rollers 46, which provides support while reducing the resistance to movement.

[0033] In another embodiment, Figure 1-4 As shown, a strip-shaped opening 13 is provided on one side of the body 10 parallel to the transmission belt 35, and the strip-shaped opening 13 is set parallel to the transmission belt 35; an observation column 47 is provided on the side of the connecting block 41, which extends through the strip-shaped opening 13 to the outside of the body 10, and the length of the strip-shaped opening 13 is greater than the length of the horizontal movement range of the observation column 47.

[0034] The observation column 47 allows the operator to observe the position of the scraper 42 from outside the machine body 10.

[0035] In another embodiment, such as Figure 2 As shown, the waste bin 11 has an opening on one side, and a collection box 14 that can be pulled out and placed inside the waste bin 11 is provided.

[0036] The collection box 14 can be removed separately for easy cleaning of debris. If it is necessary to clean or remove the scraper, the collection box 14 can be removed and the scraper can be temporarily inserted into the machine body 10 from the waste bin 11 when the scraper is on the side of the waste bin 11.

[0037] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
