The tapered part 222 is arranged between the small-diameter straight part 221 and the large-diameter straight part 223 to form an inclined angle, so that the mixture of the powder and the cooling water can enter a gap between the outer peripheral surface of the large-diameter straight part 223 and the surrounding wall of the mounting groove 213 only through a 'climbing' action to form a plurality of 'protective layers', and the mixture of the powder and the cooling water can be effectively prevented from entering the rotary connection part of the roller shaft 212 and the connecting seat 211 during the edge chamfering operation; moreover, the bristles 224 are arranged on the outer peripheral surface of the tapered part 222, and the bristles 224 are flexible, so that the normal rotation of the roller shaft 212 is not influenced even if the bristles 224 abut against the surrounding wall of the mounting groove 213, and the bristles 224 can also play a role of blocking protection, so that the mixture of the powder and the cooling water can be effectively prevented from easily entering a gap between the outer peripheral surface of the large-diameter straight part 223 and the surrounding wall of the mounting groove 213 through a climbing action during the chamfering operation, the possibility that the mixture of the powder and the cooling water enters the rotating connection part of the roller shaft 212 and the connecting seat 211 during the chamfering operation is further reduced, and the service life of the equipment is prolonged. Preferably, the bristles 224 are arranged on a reel which can be opened and closed, the reel is detachably sleeved on the outer peripheral surface of the conical part 222 and is fixed through a clamp spring, when the bristles 224 are damaged after being used for a period of time and need to be replaced, the clamp spring is detached, then the reel is pulled out of the conical part 222, and the reel with new bristles 224 is sleeved again and is fixed through the clamp spring; further preferably, the head end of the winding drum is provided with a female buckle, the tail end of the winding drum is provided with a male buckle matched with the female buckle, and the winding drum can be enclosed into a closed cavity in a buckling mode.
As shown in fig. 1, 3 and 5, in some embodiments of the present invention, a connection plate 310 is slidably connected to one side of the roller conveyor, the connection plate 310 is driven by a driving mechanism to move along the length direction of the rack 100, a chamfering grinding disc 330 driven by a first motor 320 to rotate is disposed on the connection plate 310, and a water nozzle 340 for spraying cooling water is disposed on one side of the chamfering grinding disc 330. According to the arrangement, after the roller way conveying mechanism conveys the stone to be chamfered to the chamfering station, the roller way conveying mechanism stops and clamps the stone, the first motor 320 is started to drive the chamfering grinding disc 330 to rotate, and the driving mechanism drives the stone to move along the length direction of the rack 100, so that the lower end edge of the stone is chamfered; by arranging the water spray nozzles 340, the water spray nozzles 340 spray cooling water to the contact positions of the chamfering grinding disc 330 and the stone in the chamfering operation process to reduce the temperature, so that the chamfering grinding disc 330 is prevented from being damaged due to overheating in the chamfering operation process.
As shown in fig. 3 and 5, preferably, the driving mechanism includes a lead screw 351 disposed along a length direction of the rack 100, one end of the lead screw 351 is provided with a second motor 352 for driving the lead screw 351 to rotate, the lead screw 351 is provided with a nut seat 353, the connecting plate 310 is mounted on the nut seat 353, two slide rails 354 are symmetrically disposed on two sides of the lead screw 351, and a lower end of the connecting plate 310 is slidably connected to the slide rails 354 through a slider 311. In the process of chamfering, the second motor 352 drives the lead screw 351 to rotate, and because both ends of the lead screw 351 are rotatably connected to the rack 100, in the process of rotating the lead screw 351, the slider 311 moves relative to the length direction of the lead screw 351, thereby driving the connecting plate 310 to move along the length direction of the rack 100, further driving the chamfering disk 330 to rotate and simultaneously move stably along the length direction of the rack 100, and because the nut seat 353 is driven by the lead screw 351 to feed uniformly, the chamfering disk 330 can machine chamfering with good quality on the stone. Meanwhile, the sliding rails 354 are arranged on the two sides of the lead screw 351, and the connecting plate 310 is connected to the sliding rails 354 in a sliding mode through the sliding blocks 311, so that the connecting plate 310 is guaranteed to move smoothly and stably under the driving of the lead screw 351, and the chamfering quality of the stone is further improved.
