In the embodiment, a polishing belt recycling method is disclosed, as shown in fig. 1 to 13, and includes the following steps: s1, arranging a brush strip winding roller transversely below the workbench, sleeving a brush strip which is detached from the scale breaking roller and still keeps a ring shape on the brush strip winding roller, and drawing one end of the brush strip into a steel strip flaring mechanism above the workbench;
s2, the steel belt flaring mechanism is composed of a pressing flanging wheel and a limiting wheel which are vertically arranged, the brush strip is pulled to the limiting wheel used for positioning the brush strip left and right, the left residual section and the right residual section of the grinding material wire are shifted towards the left side and the right side of the brush strip in the length direction to form an in-belt downward pressing channel, the pressing flanging wheel moves downwards along the in-belt downward pressing channel and presses the steel belt downwards, a pressing ring arranged on the pressing flanging wheel presses the steel belt in a protruding mode to perform preliminary flaring and flanging on the steel belt, and the left residual section and the right residual section are respectively located on two sides of the pressing flanging wheel and are opened outwards;
s3, continuing to drive the pressing flanging wheel to move downwards until the steel wire enters an accommodating groove formed in the pressing ring protrusion, stopping moving downwards to further perform flaring and flanging on the steel belt, and increasing the outward opening angle of the left residual section and the right residual section on the two sides of the pressing flanging wheel; keeping the current state; after flaring and flanging, the brush strip leaving the pressing flanging wheel forms a separation section;
s4, driving the pressing flanging wheel and the limiting wheel to synchronously rotate so as to drive the brush strip to feed, wherein the pressing flanging wheel is always positioned in the in-band lower pressing channel and continuously distributes the left residual section, the right residual section and the left side and the right side of the steel band along with the feeding of the brush strip; pulling and separating the steel wire and the steel belt in the separation section, wherein the abrasive wire falls off in the pulling and separating process;
s5, keeping the pressing flanging wheel and the limiting wheel to synchronously rotate so as to enable the steel belt to continuously feed, and collecting the falling grinding wires and simultaneously respectively rolling and recovering the steel belt and the steel wires until the flaring and flanging of the brush strip are completed.
The brush strip is tightly wound on the scale breaking roller, so that the original winding shape can be still kept after the brush strip is detached, namely, the shape of a ring is kept, when the brush strip is fed, only the brush strip winding roller 2 is inserted between the rings, the brush strip is sleeved on the brush strip winding roller 2, the brush strip winding roller 2 is arranged below the workbench 1, when the brush strip is split, one end of the brush strip is pulled out from the brush strip winding roller 2, then the welding section at one end of the brush strip is cut off, and then the brush strip is pulled to the upper side of the workbench 1 so as to be split.
Before the brush strip enters the flaring channel 301 in the steel strip flaring mechanism 3, the brush strip is led into the brush strip guiding mechanism 4, so that the influence of the jumping of the brush strip in the feeding process on the splitting of the brush strip is prevented. The brush bar guiding mechanism 4 is mainly composed of a lower limit wheel 402 and an upper supporting wheel 403, the upper supporting wheel 403 is a smooth wheel, and a limit groove 406 is arranged on the circumferential surface of the lower limit wheel 402. The lower limit wheel 402 is rotatably connected to a lower guide seat 405, and the lower guide seat 405 is connected to the raising seat 5 for fixing; go up to push against the wheel 403 upper end and then be connected with cylinder 409, cylinder 409 is owing to be connected to through mount pad 408 and choose high seat 5 on, and because mount pad 408 has certain thickness for the axle center of going up to push against wheel 403 and lower limit wheel 402 staggers and arranges, and staggered distance D is the thickness of mount pad 408, goes up to push against wheel 403 and is located the rear side of lower limit wheel 402 in the brush strip feed direction.
In actual production, the upper guide seat 407 is driven by the air cylinder 409 to move so as to drive the upper supporting wheel 403 to move upwards, then one end of the brush strip passes through the space between the lower limit wheel 402 and the upper supporting wheel 403 and is placed in the limit groove 406, then the air cylinder 409 drives the upper guide seat 407 to move downwards so as to drive the upper supporting wheel 403 to move and support and press the lower limit wheel 402, and at the moment, a guide channel 401 formed between the lower limit wheel 402 and the upper supporting wheel 403 is inclined so as to adapt to the bending radian of the brush strip; the brush strip has a certain radian when the flaring flanging is fed, the upper supporting wheel 403 and the lower limiting wheel 402 are arranged in a staggered mode, so that the upper supporting wheel 403 can avoid the bent radian of the brush strip, L in the figures 4 and 9 is a feeding path of the brush strip, and the brush strip has a certain bent radian, so that the brush strip is prevented from generating reverse acting force to resist guiding and flaring.
Moreover, since the degree of wear of the brush bar at each position during the actual brushing process varies, the length of the remaining abrasive filaments exposed out of the steel belt varies, and therefore, in the actual guiding of the brush bar, the position of the upper abutment wheel 403 needs to be adjusted according to the approximate exposed length of the brush bar.
