[0024] Example 1

[0025] like Figure 1-Figure 4As shown, a blade detection device for a shredder includes a feed screw 5 and a hook 8. The hook 8 is provided with a through hole 801 that matches the feed screw 5. The feed screw 5 passes through the through hole 801. The hook 8 is provided with a U-shaped groove 802. The hook 8 is clamped and connected with a connecting nut 6 through the U-shaped groove 802. The connecting nut 6 includes a cylindrical section 601. The cylindrical section 601 is provided with a clamping groove. The clamping groove includes a first flange 602 and a second flange 603. The distance between the first flange 602 and the second flange 603 is equal to the thickness of the hook 8. The U-shaped groove 802 is clamped in The design of the slot between the first flange 602 and the second flange 603 is to ensure that the hook 8 does not separate from the connecting nut 6, and to ensure the stability of the connection; a hexagonal prism section 604 is fixed at one end of the cylindrical section 601, and a connecting threaded hole 605 is provided on the cylindrical section 601 and the hexagonal prism section 604, and the connecting nut 6 is connected to the tie rod 7 by threads; since the surface of the round nut is smooth, it cannot be tightened when connected to the tie rod 7, and there is no suitable tool to tighten it on the tie rod 7, which easily leads to the connection between the connecting nut 6 and the tie rod 7 being loose and falling off the tie rod 7. Now, the hexagonal prism section 604 is provided at one end of the cylindrical section 601 to facilitate tightening the connecting nut 6 on the tie rod 7 and prevent the connecting nut 6 from loosening.

[0026] The hook 8 is provided with a slide groove 803 and a slot 804 that match the baffle 9; the baffle 9 includes a straight plate 901, one end of which is fixed with a lever 902, and the straight plate 901 is located in the slide groove 803 and the slot 804. The function of the baffle 9 is to lock the connecting nut 6 in the U-shaped groove 802 of the hook 8 to prevent the hook 8 from falling off the connecting nut 6; when the hook 8 and the connecting nut 6 need to be clamped, first pinch the lever 902 to pull the straight plate 901 out of the slide groove 803 and the slot 804, and then the baffle 9 will be locked. The hook 8 is pulled out from the slot 804, the open end of the U-shaped slot 802 is opened, and the U-shaped slot 802 is clamped between the first flange 602 and the second flange 603. The shift rod 902 is pushed to insert the straight plate 901 part of the baffle 9 into the slide groove 803 and the slot 804 until the shift rod 902 is stuck in the upper end of the slide groove 803 and cannot be pushed. The baffle 9 seals the open end of the U-shaped slot 802 of the hook 8 to prevent the hook 8 from falling off from the connecting nut 6 during the operation of the feed screw 5.

[0027] The feed screw 5 is fixedly connected to the feed rod 2, a position sensor 4 is provided on the feed rod 2, a first rotating shaft 201 is fixed on the feed rod 2, a clamping block 202 is rotatably connected to the first rotating shaft 201, the fan-shaped body 3 is rotatably connected to the fixed shaft 301, the fixed shaft 301 is fixed on the tool holder, a clamping groove is provided on the fan-shaped body 3, the clamping groove is tightly connected to the clamping block 202, a support 101 is provided at the lower end of the blade 1, the support 101 is slidably connected to the blade 1, and the support 101 is rotatably connected to the fan-shaped body 3 through the second rotating shaft 302.

[0028] Working principle:

[0029] The connecting nut 6 is tightened on the pull rod 7 through the threaded hole 605, and the U-shaped groove 802 of the hook 8 is clamped between the first flange 602 and the second flange 603 of the connecting nut 6. The straight plate 901 on the baffle 9 is inserted into the slide groove 803 and the slot 804 to seal the open end of the U-shaped groove 802 of the hook 8 to prevent the hook 8 from falling off the connecting nut 6. The feed screw 5 passes through the through hole 801 on the hook 8 and moves horizontally to the right, driving the feed rod 2 to move horizontally to the right. The position sensor 4 on the feed rod 2 will detect the displacement of the feed rod 2. The block 202 on the feed rod 2 rotates around the first rotating shaft 201. The rotation of the block 202 drives the fan-shaped body 3 to rotate counterclockwise around the fixed shaft 301. The rotation of the fan-shaped body 3 drives the support 101 to rotate around the second rotating shaft 302. The support 101 moves to the upper left and slides horizontally with the blade 1. The blade 1 is subjected to an upward force. The blade 1 moves upward within the restriction of the knife roller base 10 to complete the feeding of the blade 1. The extension amount of the blade 1 can be obtained by detecting the displacement of the feed rod 2 by the position sensor 4.

[0030] The technical solution of the present invention is to provide a slot on the connecting nut 6, and the hook 8 is clamped in the slot of the connecting nut 6 to ensure that the hook 8 will not fall off the connecting nut 6 during the movement of the feed screw 5, thereby ensuring the stable operation of the blade 1 detection device; the feed screw 5 drives the feed rod 2 to move, and the movement of the feed rod 2 drives the fan-shaped body 3 to rotate. The rotation of the fan-shaped body 3 will drive the blade 1 to move upward along the knife roller base 10, thereby realizing the feeding of the blade 1. The position sensor 4 can measure the extension amount of the blade 1 according to the position change of the feed rod 2.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
