Technical Field

[0001] The utility model relates to the field of industrial brush equipment, in particular to a grinding brush disc and a brush roller. Background Art

[0002] Strip steel is usually made by hot rolling process. During the manufacturing process, rust, oxide scale, etc. will appear on the surface of the strip steel. Before the strip steel is coiled or before the coiled strip steel is actually used, the surface of the strip steel needs to be brushed to remove the rust or oxide scale.

[0003] The patent with publication number CN212553200U applied for and authorized by the inventor provides an industrial brush equipment and a brush roller, the brush roller is provided with a plurality of circular rings, a plurality of brush strip assemblies are evenly spaced on the outer circumference of the circular rings, a groove is provided on the inner circumference of the circular rings, a key base corresponding to the circular ring groove is provided in the axial direction of the outer wall of the brush roller shaft, the plurality of circular rings are restrictedly installed on the roller shaft, and finally the brush roller shaft is installed on the industrial brush equipment, and the brush strip assemblies on the circular rings are driven to rotate by the high-speed rotation of the brush roller to perform surface treatment of the strip steel.

[0004] In the actual implementation process of the above-mentioned brush roller, small holes are opened on both sides of the brush strip assembly, the brush strip assembly passes through the ring and then folds in half, and then iron wire is passed through the small holes on both sides of the brush strip assembly to bind the brush strip assembly and tighten it, so that each brush strip assembly is fixed on the outer circumference of the ring. During the high-speed rotation of the brush roller, the brush strip assembly will shake left and right due to the resistance of rust or oxide scale, the iron wire is easy to break, and the brush strip assembly falls off before it is worn, resulting in uneven grinding. In addition, when processing small holes on the outer circumference of the ring, the processing is time-consuming due to the large number of small holes; the iron wire can only be inserted manually when punching, and the hole diameter is relatively small, and the brush strip assembly is composed of multiple small-diameter brush strips, resulting in a relatively small probability of manual insertion of the iron wire. In addition, there are many brush strip assemblies on the outer circumference of the ring, and the manual workload is large and the efficiency is low. Summary of the invention

[0005] The utility model aims to overcome the deficiencies in the prior art and to provide a grinding brush disc. The production efficiency of the grinding brush disc is improved by passing each brush strip through a ring sheet and welding and fixing the folded brush strip strands by ultrasonic method.

[0006] Furthermore, a brush roller is provided, wherein the grinding brush discs are stacked on the roller body and fixed to the roller body in the circumferential direction.

[0007] The technical solution of the utility model is achieved in this way:

[0008] A grinding brush disc includes a ring sheet and a brush strip. The inner side of the outer circumference of the ring sheet is provided with a plurality of through holes along the circumferential direction. After passing through the through holes, the brush strip is folded in the direction away from the outer circumference of the ring sheet. Each folded brush strip forms two bundles of strands. The two bundles of strands are fixed by ultrasonic welding near the outer circumference of the ring sheet. The brush strip is folded in half to form two bundles of strands, which increases the number of brush heads of the grinding brush and makes the grinding brush strip steel more thorough. The two bundles of strands are fixed by ultrasonic welding. The ultrasonic welding strength is close to the brush strip assembly body, which can achieve efficient, clean and energy-saving welding. The welding strength is high and it is also easy to realize automated production to improve production efficiency.

[0009] Preferably, the through holes are evenly distributed along the outer circumference of the ring piece. The evenly distributed through holes on the outer circumference of the ring piece enable the brush strips to be evenly distributed on the outer circumference of the ring piece, and when the brush roller rotates at high speed, the brush strips on each ring piece can evenly brush the strip steel.

[0010] Preferably, the brush strip strand is composed of multiple brush strips, and the brush strips are based on resin material. The diameter of a single brush strip is small, and multiple brush strips form the brush strip strand, so that the strength of the brush strip strand is increased, which is more conducive to brushing; the brush strip resin material as a matrix can realize ultrasonic welding.

[0011] Preferably, after the brush strands are melted under the action of ultrasound, welding strips are formed at corresponding welding positions, and the welding strips fix the two folded strands. The brush strands are formed into welding strips under the action of ultrasound, and the welding strips fix the two strands on the outer circumference of the ring sheet, so that the brush strands will not be scattered and fall off under force during the brushing process.

[0012] Preferably, a brush plate further includes an annular belt, which surrounds the outer circumference of the annular sheet and is concentric with the annular sheet. The annular belt passes through all brush strips and is sandwiched between two bundles of strands at the overlap with each brush strip. The position where the annular belt passes through the brush strips corresponds to the welding position of the brush strips, so that the annular belt and the brush strips are fixed together by ultrasonic welding. The annular belt is added between the brush strips, and the inner sides of the two bundles of strands are melted and fixed on the annular belt during welding, so that the position of the brush strips is more stable during grinding.

[0013] Preferably, during ultrasonic welding, the inner side of the strands contacting the annular belt forms a welding zone, which increases the welding strength of the brush strips, and the two strands are not easily disconnected during high-speed brushing.

[0014] Preferably, the cross section of the annular belt is flat or circular, and the width of the annular belt is 0.5-3 mm. The flat or circular annular belt facilitates the inner contact of the two strands and is conducive to ultrasonic welding; the width range of the annular belt is not only set to cooperate with ultrasonic welding, but also can be selected according to the size of the brush load.

[0015] Preferably, the material of the endless belt is resin or plastic, which is more conducive to ultrasonic welding and melting.

[0016] Preferably, the radius of the annular band is 3-12 mm larger than the radius of the outer circumference of the ring sheet. The setting of the radius of the annular band enables the ultrasonic wave to weld and fix the brush strip strands to the annular band at a position close to the outer circumference of the ring sheet during welding without interfering with the ring sheet to affect the welding and the life of the ultrasonic welding head.

[0017] Furthermore, a brush roller is provided, comprising the above-mentioned grinding brush discs and a roller body, wherein the grinding brush discs are stacked on the roller body, and each grinding brush disc is circumferentially fixed to the roller body. The grinding brush discs are stacked on the roller body, so that the brush rod forms a certain length of dense brush strips; the grinding brush discs are circumferentially fixed to the roller body, and when the brush rod rotates at high speed, it can rotate with the grinding brush discs to grind the strip steel.

[0018] The design starting point, concept and beneficial effects of the utility model using the above technical solution are:

[0019] The technical solution folds the brush strips on the ring sheet of the grinding brush disc in half, and welds and fixes each of the folded brush strips in half by ultrasonic method.

[0020] The method of fixing the folded brush strip strands with ultrasonic welding can weld the brush strip strands efficiently, cleanly and energy-savingly, and improve the welding and fixing strength of the brush strip strands; it can also realize automatic welding, reduce labor costs, and improve the production efficiency of manufacturing grinding brush discs.

A plurality of through holes 101 are evenly arranged on the inner side of the outer circumference of the ring plate 1 along the circumferential direction. The brush strip strand 2 is composed of a plurality of brush strips, and the brush strips are based on resin material.

[0028] Specifically, Figure 1 and Figure 2 As shown, the brush strip strands 2 pass through the through hole 101 and are folded in half away from the outer circumference of the ring piece 1. Each folded brush strip strand 2 forms two bundles of strands 2a. The two bundles of strands 2a are fixed by ultrasonic welding and melting at positions close to the outer circumference of the ring piece 1. The brush strip strands 2 melt under the action of ultrasonic waves to form a circle of welding strips 201 at the corresponding welding positions. The welding strips 201 fix the two folded bundles of strands 2a.

[0029] Embodiment 2: This embodiment differs from Embodiment 1 in that Figure 3 , 4 As shown, a grinding brush disc also includes an annular band 3, the radius of which is 3-12mm larger than the radius of the outer circumference of the ring piece 1, the annular band 3 is concentric with the ring piece 1 and surrounds the outer circumference of the ring piece 1, the annular band 3 is made of resin or plastic, its cross-section is flat or circular, and the width of the annular band 3 is 0.5-3mm; the annular band 3 passes through all the brush strips 2 and is sandwiched between two bundles of sub-strands 2a at the overlap with each brush strip 2, the position where the annular band 3 passes through the brush strips 2 corresponds to the welding position of the brush strips 2, so that the annular band 3 and the brush strips 2 are fixed together by ultrasonic welding; the brush strips 2 melt under the action of ultrasonic waves, not only forming a circle of welding strips 201 at the corresponding welding position, but also forming a welding band 202 at the inner part of the sub-strand 2a that contacts the annular band 3.

[0030] Further explanation, both Example 1 and Example 2 use ultrasonic welding to weld and fix the folded brush strips. Ultrasonic welding is easy to automate and improve production efficiency.
