When the existing brush strip polishes a rusted steel plate, the surface of a polishing object is contacted and polished by the scale breaking roller, the abrasive wire is a consumable material, the exposed abrasive wire at the upper end of the steel belt is gradually worn in the polishing process, the abrasive wire cannot be continuously used when worn to the upper end of the steel belt for about 1cm long, otherwise, the shorter abrasive wire can make the steel belt and the polishing object generate touching friction in the rust removing process, the rust removing cannot be polished, the steel belt and the polishing object can be damaged, and the rest abrasive wire comprises left residual sections and right residual sections which are respectively positioned at two sides of the steel wire; while the left and right remaining segments are generally in parallel or intersecting states. When polishing cannot be continued, the brush bar is generally removed and replaced with a new brush bar to continue rust removal. The brush strip can be recovered after being taken down, and the recovery method disclosed in the invention patent No. CN202011576641.3 is characterized in that firstly, steel wires in one end of the brush strip are forcibly pulled out, the steel wires are fixed on a steel wire rolling disc, and the steel belt is driven to feed by a plurality of groups of shaping wheels to press the flanging at two sides of the steel belt to be flat and then is rolled up, so that the brush strip can be separated and recovered finally.

The mode adopts forced drawing and driving of the brush bar to feed, and the larger bending deflection of the brush bar can lead the brush bar to generate reverse acting force to resist, and the steel belt and the abrasive wire in the brush bar have certain rigidity, so the requirements on equipment are higher; in actual production, a plurality of groups of shaping wheels for flaring and flanging the steel belt are also frequently damaged, flaring and flanging cannot be continuously carried out, shutdown adjustment is needed, and production efficiency is reduced.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a polishing belt recycling treatment method, which is characterized in that after a grinding wire excess material section is firstly allocated and the pressing depth of a pressing flanging wheel is increased, the pressing flanging wheel is enabled to perform flaring flanging, so that the steel belt can be flared flanging while the grinding wire excess material section is automatically allocated in the follow-up continuous flaring flanging, the requirement on equipment is lower, the stability is higher, and the production efficiency is effectively improved.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a polishing belt recycling method comprises the following steps:
s1, transversely arranging a brush strip winding roller below a workbench, sleeving a brush strip which is detached from a descaling roller and still keeps a ring shape on the brush strip winding roller, and pulling 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 arranged up and down, the brush strip is pulled to the limiting wheel for positioning the brush strip left and right, a left residual section and a right residual section of the abrasive wire are stirred towards the left side and the right side of the length direction of the brush strip to form an in-band pressing down channel, the pressing flanging wheel moves downwards along the in-band pressing down channel and presses down into the steel belt, a pressing ring arranged on the pressing flanging wheel is pressed into the steel belt in a protruding manner to perform preliminary flaring flanging on the steel belt, and the left residual section and the right residual section are respectively positioned at two sides of the pressing flanging wheel to be opened outwards;
s3, continuously driving the pressing flanging wheel to move downwards until the steel wire enters a containing groove formed in the pressing ring protrusion, stopping moving downwards so as to further perform flaring flanging on the steel belt, and increasing the outwards-opened angles of the left residual section and the right residual section positioned at the two sides of the pressing flanging wheel; maintaining the current state; the strip-shaped brush separating section which leaves the pressing flanging wheel after flaring flanging;
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 pressing channel and continuously distributes left and right left residual sections and left and right sides of the steel strip along with the feeding of the brush strip; pulling and separating the steel wire from the steel belt in the separation section, wherein the abrasive wire falls off in the pulling and separating process;
s5, the pressing flanging wheel and the limiting wheel are kept to synchronously rotate so as to enable the steel belt to continuously feed, and the steel belt and the steel wire are respectively rolled and recovered while the dropped abrasive wires are collected in the feeding process until the flaring flanging of the brush strip is completed.
The brush strip winding roller is arranged so as to facilitate the feeding of the brush strip, and the brush strip still maintains the original winding shape, namely the ring-shaped shape, when being detached from the descaling roller, and after being sleeved on the brush strip winding roller, the brush strip is driven to feed so as to pull the brush strip winding roller to rotate together. Then, one end of the brush strip is pulled to the limiting wheel, the left remaining section and the right remaining section of the abrasive wire are stirred to form an in-band downward pressing channel at two sides, so that the left remaining section and the right remaining section can be conveniently placed in a state of being opened to two sides all the time when the abutting flanging wheel is pressed down, and the left remaining section and the right remaining section can be allocated and pressed to the left side and the right side together with the left side and the right side of the steel belt when the abutting flanging wheel is pressed down.
The holding groove which is arranged on the abutting-pressing flanging wheel in a protruding manner and used for abutting the pressing ring can enable the depth of the abutting-pressing ring which is pressed down to be deeper, on one hand, the steel belt can be further flared and flanging, on the other hand, the left remaining section and the right remaining section can be opened to be larger in angle, so that the steel wire is distributed more thoroughly, the steel wire is exposed and then is pulled out more easily, and the abrasive wire is also taken out more easily. In the flaring flanging process, the abutting flanging wheel is always positioned in the in-band pressing down channel, so that the left remaining section and the right remaining section in the steel band can be allocated to the left side and the right side by the abutting ring in a protruding manner in the feeding process of the brush strip, and the left side and the right side of the steel band can be flared flanging. The synchronous rotation of the pressing flanging wheel and the limiting wheel can drive the brush strip to continuously feed, and meanwhile, the flaring flanging is stable, and slipping is avoided.
In a further scheme, in the step S2, two outer eaves are formed at the notch of the accommodating groove by pressing the flanging wheel, and the thickness of the two outer eaves is set in the range of 0.5-1.5mm, so that the pressing ring is pressed down into the steel belt.
The smaller the thickness of the outer eave is, the smaller the distance between the outer sides of the two outer eaves at the notch is, the easier the steel strip is to be pressed down from the in-band pressing channel into the steel strip in the pressing process, and the easier and smoother the steel strip is when the steel strip is pressed down to abut against the press ring and then be flared and turned over on the left side and the right side.
In a further scheme, in the step S2, the limiting wheel is provided with a limiting ring groove matched with the pressing ring protrusion, the brush strip is placed in the limiting ring groove when preliminary flaring flanging is carried out, and the pressing ring protrusion is accurately moved from the in-band pressing channel to the inside of the steel belt to realize flaring flanging and avoid steel wires through positioning of the limiting ring groove.
The limiting ring groove can limit the brush strip when the brush strip is fed, prevent the offset of the brush strip and facilitate the initial positioning of the brush strip when the brush strip is initially fed, and can accurately position the brush strip by only pulling the brush strip into the limiting ring groove, and the edge pressing and flanging wheel is aligned to the middle position of the steel strip when being pressed downwards, and can cooperate with the edge pressing ring to perform flaring and flanging on the steel strip.
In a further scheme, before the step S2 is carried out, a brush bar guiding mechanism is further arranged on the workbench, and the brush bar guiding mechanism is formed by matching upper supporting wheels and lower limiting wheels which are arranged up and down; the upper propping wheel is arranged at the rear side of the lower limiting wheel in the feeding direction of the brush strip, and the upper propping wheel and the axle center of the lower limiting wheel are staggered to form an inclined guide channel so as to conform to the bending radian of the brush strip and prevent the brush strip from jumping off and shifting, and the brush strip is led into the guide channel and then pulled between the propping flanging wheel and the limiting wheel.
The brush strip guiding mechanism is used for stably feeding the brush strip, the shaking condition in the feeding process does not occur, the upper supporting wheel and the lower limiting wheel are arranged in a staggered mode, so that an inclined guiding channel is formed between the upper supporting wheel and the lower limiting wheel, the inclined guiding channel can avoid the bending radian of the brush strip during feeding, the brush strip is prevented from generating a reaction force to resist feeding and flaring flanging, and meanwhile the guiding channel can also prevent the brush strip from tripping during feeding.
In a further scheme, limit grooves are formed in the circumferential surface of the lower limit wheel to limit the left and right deflection of the brush strip, and the upper supporting wheel is a smooth wheel with a smooth surface.
The limiting groove arranged on the lower limiting wheel can limit the brush strip left and right, prevent the brush strip from shifting, and can effectively prevent the brush strip from tripping and deflecting by being matched with the limiting of the upper supporting wheel in the upper and lower directions.
In a further scheme, the specific working steps of the brush bar guiding mechanism are as follows: according to the exposed length of the abrasive wire on the brush strip, the upper supporting wheel is adjusted to a position 1-2cm away from the upper end of the abrasive wire, and when the brush strip is driven to feed, the upper supporting wheel and the lower limiting wheel cooperate to limit the trip deflection of the brush strip.
The lengths of the exposed steel strips of the abrasive wires are different due to different degrees of abrasion of the brush strips, the smooth feeding of the brush strips can be allowed at intervals of 1-2cm, and meanwhile, the condition that the brush strips jump out of the limit grooves can not occur.
In a further scheme, before the step S2 is carried out, the welding section at the end part of the brush bar is cut off in advance, so that the pressing ring is pressed into the steel belt in a protruding mode.
In a further scheme, the steel strip is pulled downwards while the steel wire exposed in the step S5 is pulled upwards, by the following means: the steel belt and the steel wire are led into a flow dividing device, the flow dividing device is at least composed of a scraping rod which is vertically arranged in the feeding direction of the brush bar, and the steel belt and the steel wire respectively pass through abrasive wires which are used for dividing and scraping the steel wire from the upper side and the lower side of the scraping rod.
The split device can be convenient for automatically separating the steel wire and the steel belt from each other, does not need to be manually pulled all the time after flaring and flanging, and can scrape abrasive wires possibly adhered on the steel wire by the scraping rod when the steel belt and the steel wire are separated.
In a further aspect, the brush bar is introduced into the pre-guide assembly prior to feeding the brush bar into the brush bar guide mechanism; the pre-guide assembly is composed of two brush strip guide rollers which are symmetrically and vertically connected to the front side of the brush strip guide mechanism, and the length of the brush strip guide path is increased by matching with the brush strip guide mechanism.
The pre-guide assembly can prolong the length of the brush strip guide path, so that the brush strip can be pre-guided before entering the guide mechanism, the guide of the brush strip is smoother, and the brush strip is prevented from deflecting greatly in the feeding direction while being adapted to the bending radian of the brush strip.
In a further scheme, the synchronous rotation of the pressing flanging wheel and the limiting wheel drives the brush strip to feed in the following manner: the pressing flanging wheel and the limiting wheel are respectively connected with the output end of the gear box through two universal shafts, and the motor drives the gear box to rotate so as to drive the universal shafts to synchronously rotate.
Compared with the prior art, the invention has the beneficial effects that:
1. the abrasive wire excess material sections are allocated firstly, and then the pressing flanging wheel is pressed downwards to perform preliminary flaring flanging, so that the pressing flanging wheel can automatically allocate the abrasive wire excess material sections while carrying out flaring flanging on the steel belt, and the subsequent separation and recovery are facilitated;
2. the holding groove arranged on the pressing flanging wheel can avoid the obstruction of the steel wire, and can improve the pressing depth of the pressing flanging wheel, so that the flaring flanging effect is better, and the distribution of the abrasive wire excess material section is smoother;

Detailed Description
The following describes the embodiments of the present invention in detail with reference to the drawings.
In this embodiment, a polishing belt recycling method is disclosed, as shown in fig. 1-13, comprising the following steps: s1, transversely arranging a brush strip winding roller below a workbench, sleeving a brush strip which is detached from a descaling roller and still keeps a ring shape on the brush strip winding roller, and pulling 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 arranged up and down, the brush strip is pulled to the limiting wheel for positioning the brush strip left and right, a left residual section and a right residual section of the abrasive wire are stirred towards the left side and the right side of the length direction of the brush strip to form an in-band pressing down channel, the pressing flanging wheel moves downwards along the in-band pressing down channel and presses down into the steel belt, a pressing ring arranged on the pressing flanging wheel is pressed into the steel belt in a protruding manner to perform preliminary flaring flanging on the steel belt, and the left residual section and the right residual section are respectively positioned at two sides of the pressing flanging wheel to be opened outwards;
s3, continuously driving the pressing flanging wheel to move downwards until the steel wire enters a containing groove formed in the pressing ring protrusion, stopping moving downwards so as to further perform flaring flanging on the steel belt, and increasing the outwards-opened angles of the left residual section and the right residual section positioned at the two sides of the pressing flanging wheel; maintaining the current state; the strip-shaped brush separating section which leaves the pressing flanging wheel after flaring flanging;
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 pressing channel and continuously distributes left and right left residual sections and left and right sides of the steel strip along with the feeding of the brush strip; pulling and separating the steel wire from the steel belt in the separation section, wherein the abrasive wire falls off in the pulling and separating process;
s5, the pressing flanging wheel and the limiting wheel are kept to synchronously rotate so as to enable the steel belt to continuously feed, and the steel belt and the steel wire are respectively rolled and recovered while the dropped abrasive wires are collected in the feeding process until the flaring flanging of the brush strip is completed.
The brush strip is tightly wound on the scale breaking roller, so that the original winding shape, namely the ring shape, can be maintained after the brush strip is detached, therefore, when the brush strip is fed, only the brush strip winding roller 2 is needed to be inserted between the rings, so that 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 detached, one end of the brush strip is pulled out of 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 above the workbench 1 so as to be detached.
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 as to prevent the brush strip from jumping in the feeding process to influence the splitting of the brush strip. The brush bar guiding mechanism 4 mainly comprises a lower limit wheel 402 and an upper supporting wheel 403, wherein 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 the lower guide seat 405, and the lower guide seat 405 is connected to the raising seat 5 for fixing; the upper end of the upper supporting wheel 403 is connected with an air cylinder 409, the air cylinder 409 is connected to the raising seat 5 through a mounting seat 408, and the mounting seat 408 has a certain thickness, so that the axes of the upper supporting wheel 403 and the lower limiting wheel 402 are staggered, the staggered distance D is the thickness of the mounting seat 408, and the upper supporting wheel 403 is positioned at the rear side of the lower limiting wheel 402 in the brush strip feeding 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 between the lower limiting wheel 402 and the upper supporting wheel 403 and is placed in the limiting groove 406, and then the air cylinder 409 also drives the upper guide seat 407 to move downwards so as to drive the upper supporting wheel 403 to move and press against the lower limiting wheel 402, wherein a guide channel 401 formed between the lower limiting wheel 402 and the upper supporting wheel 403 is inclined so as to adapt to the bending radian of the brush strip; the brush bar has a certain radian when the flaring is turned over, and the staggered arrangement of the upper supporting wheel 403 and the lower limiting wheel 402 enables the upper supporting wheel 403 to avoid the bending radian of the brush bar, L in fig. 4 and 9 is the feeding path of the brush bar, and the brush bar has a certain bending radian, so that the brush bar is prevented from generating reverse acting force to resist the guiding and flaring.
Moreover, since the abrasion degree of the brush bar is different at each position in the actual brushing process, the lengths of the remaining abrasive wires exposed out of the steel belt are also different, so that in the actual guiding of the brush bar, the position of the upper supporting wheel 403 needs to be adjusted according to the approximately exposed length of the brush bar. When the exposed length of the rest abrasive wires is longer, the cylinder 409 drives the upper supporting wheel 403 to move to the position of 1-2cm, preferably 1cm, of the upper end of the abrasive wires, so that the part with the longer abrasive wires can pass through, is not blocked, and can limit the brush strip to jump out of the guide channel 401, thereby affecting the subsequent flaring and flanging; when the exposed length of the rest abrasive wires is shorter, the cylinder 409 drives the upper supporting wheel 403 to move and press against the circumferential surface of the lower limiting wheel 402, so that the brush strip can only move and feed in the limiting groove 406, and is not easy to trip.
