Description

Technical Field

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

[0002] Plates and strips are usually made by hot rolling process. Before actual use, rust, oxide scale, etc. will appear on the surface of the plate and strip, and the surface of the plate and strip needs to be brushed by brush rollers. To facilitate disassembly and maintenance, the structure of the brush roller is configured to have multiple brush discs mounted on the roller shaft, and the brush discs are circumferentially fixed to the roller shaft by key connection.

[0003] Announcement No. CN212553200 discloses a brush roller, which has multiple circular rings sleeved on the roller shaft, multiple through holes evenly spaced on the outer circumference of the circular rings, brush strip assemblies passed through the through holes, small holes are opened on both sides of the through holes through which the brush strip assemblies are passed on the circular rings, the brush strip assemblies are folded in half after passing through the through holes, and then iron wires are passed through the small holes on both sides of the brush strip assemblies to bundle the brush strip assemblies and tighten them, so that each brush strip assemblies are fixed on the outer circumference of the circular rings; but such a brush roller has disadvantages.

[0004] During the high-speed rotation of the brush roller, the brush bar assembly contacts the surface of the plate and strip when grinding the rust or oxide scale on the plate and strip, causing the brush bar assembly to swing left and right due to resistance. Since the only thing limiting the swing of the brush bar is the through hole on the ring, the swing amplitude of the brush bar is too large. After long-term use, the iron wire may loosen, causing the brush bar assembly on the brush roller to fall off before it is completely worn out, affecting the service life of the brush roller and subsequent plate and strip production. Summary of the invention

[0005] The utility model provides a brush disc, by arranging a plurality of inner and outer opposite through holes and positioning notches at intervals along the circumferential direction on the disc body, so that a limiting portion is formed between two positioning notches, the limiting portion can reduce the swing amplitude of the brush strip assembly, and reduce the risk of the brush strip assembly detaching from the disc body.

[0006] Furthermore, a brush roller is provided, in which multiple brush plates are sleeved on a roller shaft and the brush plates and the roller shaft are kept circumferentially fixed. The brush roller manufactured in this way reduces the number and cost of replacing the brush strips, and improves the service life of the brush roller and the subsequent production efficiency of the plate and strip.

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

[0008] A brush plate, comprising:

[0009] A disc body, wherein a plurality of through holes are arranged at intervals along the circumferential direction on the inner side of the outer circumference of the disc body, and a plurality of positioning notches are arranged along the circumferential direction on the outer side of the disc body corresponding to the positions of the through holes, and a limited position portion is formed between every two positioning notches;

[0010] The brush strip assembly comprises a plurality of parallel wires, which pass through the through hole and are folded in half in the outer circumferential direction away from the disc body and then close to each other, thereby forming two branches in the positioning notch, and the two branches are connected and fixed and then restricted between two adjacent limiting parts.

[0011] Preferably, the through holes and positioning notches are evenly distributed along the circumference of the disc body; the even distribution can make the grinding effect of the brush strip assembly more uniform and stable.

[0012] Preferably, along the radial direction of the disc body, the length of the limiting portion ranges from 3 to 7 mm.

[0013] Preferably, the two branch connections are fixed in the positioning notch, so that the limiting portion can better limit the swing of the brush strip assembly.

[0014] Preferably, the two branches are fixed in the positioning notch by ultrasonic welding to form a welding band, and the welding band is confined between two adjacent limiting parts; the ultrasonic welding method is simple and efficient, and has a good fixing effect.

[0015] Preferably, the two branches are fixed in the positioning notch by winding iron wire to form a winding belt, and the winding belt is confined between two adjacent limiting parts.

[0016] Preferably, the positioning notch is an outwardly open U-shaped notch, and the limiting portion is a rectangular plate structure between every two U-shaped notches; the U-shaped notch can accommodate enough filaments to make the brush disc have a better brushing effect, and the rectangular plate structure can provide a stable limiting force for the brush strip assembly.

[0017] Preferably, along the circumferential direction of the disk body, the width of the U-shaped notch ranges from 5 to 15 mm.

[0018] A brush roller comprises the above-mentioned brush disc and a roller shaft, wherein a plurality of brush discs are sleeved on the roller shaft, and each brush disc is circumferentially fixed to the roller shaft.

[0019] The beneficial effects of the utility model using the above technical solution are:

[0020] The outer circumference of the brush disc body is provided with positioning notches corresponding to the positions of the corresponding through holes, and a limiting portion is formed between every two positioning notches. After the brush strip assembly is passed through the through hole, the limiting portion is equivalent to adding a limiting force to the brush strip assembly to limit the swing of the brush strip assembly. In this way, when the brush strip assembly rubs the brush plate belt, the brush strip assembly will not separate from the disc body due to insufficient limiting force.

[0021] A plurality of brush discs are mounted on a roller shaft and assembled with the roller shaft to form a brush roller. When such a brush roller is used to grind a brush strip, the brush strip assembly will not often fall off, and there is no need to replace and maintain the brush strips of the brush roller, thereby reducing the number and cost of replacing the brush strips and increasing the service life of the brush roller and the production efficiency of subsequent strips.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1-5 As shown, the utility model has multiple implementation modes, and the specific implementation modes are as follows:

[0031] Example 1: Figure 1-4 As shown, this embodiment provides a brush plate, including:

[0032] The disk body 1 is a circular ring structure, wherein a plurality of through holes 11 are arranged at intervals along the circumferential direction on the inner side of the outer circumference of the disk body 1, and a plurality of positioning notches 14 are arranged along the circumferential direction on the outer side of the outer circumference of the disk body 1, which are opposite to the through holes 11, and a limited position portion 12 is formed between every two positioning notches 14;

[0033] The brush bar assembly comprises a plurality of side-by-side filaments 2, which are made of a resin material as a matrix. The filaments 2 pass through the through holes 11 and are folded in half in a direction away from the outer circumference of the disc body 1 and then brought together to form two sub-strands 21 in the positioning notch 14. After the two sub-strands 21 are connected and fixed, they are restricted between two adjacent limiting portions 12, so that the swing amplitude of the brush bar assembly when brushing the plate belt is within a reasonable range.

[0034] Furthermore, the through holes 11 and the positioning notches 14 are evenly distributed along the circumference of the disc body 1; the even distribution can make the grinding effect of the brush strip assembly more uniform and stable.

[0035] Furthermore, along the radial direction of the disc body 1, the length range of the limiting portion 12 is 3-7 mm, and this length range is relatively reasonable, so that the limiting portion 12 can provide sufficient limiting force for the swinging brush strip assembly.

[0036] Furthermore, the two strands 21 are connected and fixed at the position within the positioning notch 14; specifically, the two strands 21 are fixed in the positioning notch 14 by ultrasonic welding, the strands 21 melt under the action of ultrasonic waves, and welding bands 22 are formed at the corresponding welding positions, and the welding bands 22 fix the two folded strands 21; the welding bands 22 are limited between two adjacent limiting portions 12; the ultrasonic welding method is simple and efficient, and has a good fixing effect. After being fixed, the brush strip assembly is in the positioning notch 14. When grinding the brush plate strip, the welding band 22 on the brush strip assembly can have sufficient contact area with the limiting portion 12, so that the limiting portion 12 can better limit the swing of the brush strip assembly.

[0037] Furthermore, the positioning notch 14 is a U-shaped notch open outward, and the limiting portion 12 is a rectangular plate structure between every two U-shaped notches; along the circumferential direction of the disc body 1, the width range of the U-shaped notch is 5-15mm. The U-shaped notch has a reasonable structure and a moderate width, which can accommodate enough filaments to make the brush disc have a better brushing effect, and the limiting portion 12 of the rectangular plate structure can provide a stable limiting force for the brush strip assembly.

[0038] A brush roller is further provided, comprising the above-mentioned brush disc and a roller shaft (not shown), wherein a plurality of brush discs are sleeved on the roller shaft, and each brush disc is circumferentially fixed to the roller shaft; specifically, a slot 13 is provided on the inner circle of the disc body 1, and a key slot (not shown) is provided on the roller shaft, and each brush disc is circumferentially fixed to the roller shaft by the key respectively cooperating with the slot 13 and the key slot, so as to realize synchronous rotation.

[0039] Embodiment 2: This embodiment is different from the above embodiment in that Figure 5As shown, the brush strip assembly is fixed by winding with iron wire. Specifically, the two branches 21 are fixed by winding with iron wire in the positioning notch 14 and a winding belt 23 is formed. The winding belt 23 is limited between two adjacent limiting parts 12. The iron wire winding method can also be used to fix the two branches 21 of the brush strip assembly. The winding belt 23 can also contact with the limiting part 12 when the brush strip assembly swings, thereby increasing the limiting force of the brush strip assembly, thereby achieving the same effect as in Example 1.

[0040] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
