Description

Technical Field

[0001] The utility model belongs to the technical field of watch cover polishing tools and relates to a 3D watch cover bevel brush. Background Art

[0002] In order to ensure aesthetics and functionality, the groove walls of the 3D watch cover need to be polished. The use of a brush is low-cost and has moderate hardness and softness. It can effectively remove fine particles, dirt and oxide layers on the surface while avoiding scratches or damage. Traditional manual polishing requires people to hold a brush to operate, which is less efficient.

[0003] To this end, the Chinese patent application (application number: 201920406451.3) discloses a disc-type glass polishing brush, comprising a substrate and a large number of polishing brushes, the substrate comprising a fixed surface and a mounting surface, comprising a substrate and a large number of polishing brushes, the substrate is in the shape of a "disc", the upper and lower surfaces of the substrate are respectively the fixed surface and the mounting surface, a central through hole is provided at the center of the substrate, a guide hole passing through the substrate is provided on the mounting surface, a large number of polishing brushes are arranged on the fixed surface, the diameters of the substrate, the fixed surface and the mounting surface are the same, a large number of vertical blind holes of the same diameter are arranged in a "pyramid" manner around the center of the circle on the fixed surface, the polishing brush is composed of several bristles of the same length, the polishing brush is gap-fitted with the vertical blind hole, one end of the bristle is fixed with glue, a large number of polishing brushes are vertically arranged one by one on the vertical blind holes of the fixed surface, a large number of polishing brushes are fixed one by one on the vertical blind holes with glue, and several screw through holes of the same diameter are equidistantly provided on the periphery of the substrate.

[0004] However, the above method has the following drawbacks: 1. The polishing brushes installed on the fixed surface have uniform hardness, making it difficult to achieve a balance between softness and grinding force, thus limiting the polishing effect. 2. The polishing brush bristles are arranged substantially perpendicular to the fixed surface, making it difficult to adapt to complex or irregular grooves, making it difficult to fully polish the edges, corners, and walls of the grooves, thus affecting the polishing effect and making it less suitable for use. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a special-shaped crystal printing jig. The technical problem to be solved by this utility model is: how to ensure the polishing effect while improving the applicability.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a 3D watch cover bevel brush, comprising a base plate, on which bristles, a plurality of guide holes and a mounting hole for connecting a power source are provided, characterized in that an inclination angle is formed between the bristles and the surface of the base plate, and the bristles include soft bristles and hard bristles.

[0007] When working, align the brush with the surface of the product and bring it close to it. The power source drives the brush to rotate, and the polishing liquid flows through the guide holes, and the bristles polish the product. The bristles include soft bristles and hard bristles. The soft bristles give the brush a certain softness, while the hard bristles provide sufficient grinding force to ensure the polishing effect. An inclined angle is formed between the bristles and the surface of the substrate. Even for complex or irregular grooves, the bristles can effectively contact the edges, corners and walls of the grooves and fully polish them, ensuring the polishing effect while improving applicability. The setting of the guide holes can effectively guide the flow of polishing liquid and evenly distribute the polishing liquid. Reasonable setting of the guide holes can control the amount of polishing liquid used, avoid unnecessary waste, and improve economic efficiency.

[0008] The 3D beveled cover brush features alternating soft and hard bristles arranged circumferentially along the substrate. This arrangement evenly covers the substrate surface, allowing different areas to be polished simultaneously, thereby improving overall polishing uniformity and effectiveness. This alternating arrangement leverages the flexibility of the soft bristles and the abrasive force of the hard bristles within the same polishing process, achieving a more uniform polishing effect and effectively treating surfaces of varying materials. This alternating arrangement reduces wear on a single brush type, extending the lifespan of the entire brush, thereby reducing replacement frequency and maintenance costs.

[0009] The 3D beveled brush for watch covers features alternating soft and hard bristles along the substrate's radial direction. This alternation not only circumferentially but also radially creates a more even arrangement of soft and hard bristles, improving overall polishing uniformity and effectiveness, effectively treating surfaces of varying materials, and significantly reducing wear on a single brush type.

[0010] The above-mentioned 3D watch cover bevel brush, the soft bristles are made of rubber wire, and the hard bristles are made of sisal. The rubber wire has good flexibility and wear resistance, and can provide a better soft touch during the polishing process, reducing the risk of scratching soft surfaces. At the same time, the elasticity of the rubber wire enables it to effectively adapt to irregular shapes when contacting the surface, ensuring comprehensive polishing. Sisal is a tough and durable natural fiber with a high grinding force, which is suitable for polishing hard surfaces. At the same time, the hard bristles of sisal can effectively remove surface dirt and scratches, and improve the polishing effect. Both rubber wire and sisal are relatively environmentally friendly materials, which reduce dependence on synthetic materials, reduce the possibility of environmental pollution, and are in line with the trend of sustainable development.

[0011] The angle between the bristles and the substrate surface of the 3D cover bevel brush is 50° to 70°. This angle is within a suitable range, allowing the bristles to adhere closely to the substrate surface while ensuring evenly distributed contact pressure between the bristles and the substrate surface, avoiding localized overpressure or underpressure, thus balancing efficiency and service life, and ensuring a polishing effect.

[0012] The above-mentioned 3D watch cover bevel brush has at least one circle of guide holes circumferentially provided on the substrate. The guide holes arranged along the circumference can guide the flow of the polishing liquid more evenly, ensuring that the liquid is evenly distributed between the bristles, avoiding local liquid concentration or insufficiency, and the bristles can make full use of the polishing liquid during the polishing process, so that each contact area can be properly lubricated and ground, ensuring the polishing effect. When processing surfaces of different shapes or structures, the circumferential guide holes can adapt to different flow requirements, ensuring that a good polishing effect can be maintained on surfaces of complex shapes. Reasonably designed circumferential guide holes can control the amount of polishing liquid used, avoid waste caused by liquid concentration, and thus improve economy and environmental protection.

[0013] The aforementioned 3D watch cover bevel brush features at least two circumferential rings of guide holes on the base plate, with adjacent rings staggered radially along the base plate. This staggered arrangement not only guides the polishing fluid more evenly but also reduces the risk of a single hole becoming clogged. Even if one guide hole fails due to dirt or material accumulation, the remaining guide holes still ensure continuous flow of polishing fluid, unimpeding the polishing process.

[0014] Compared with the existing technology, this 3D watch cover bevel brush has the following advantages:

[0015] 1. The bristles of this 3D watch cover bevel brush include soft bristles and hard bristles. The soft bristles make the brush soft, while the hard bristles provide sufficient grinding force to ensure the polishing effect.

[0016] 2. In this 3D watch cover bevel brush, an inclination angle is formed between the bristles and the substrate surface. Even for complex or irregular grooves, the bristles can effectively contact the edges, corners and walls of the grooves and fully polish them, ensuring the polishing effect while improving applicability.

[0017] 3. In this 3D watch cover bevel brush, the setting of the guide holes can effectively guide the flow of polishing liquid and make the polishing liquid evenly distributed. Reasonable setting of the guide holes can control the amount of polishing liquid used, avoid unnecessary waste, and improve economy. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the 3D watch cover bevel brush includes a base plate 1, on which bristles 2, a plurality of guide holes 3 and a mounting hole 4 for connecting a power source are provided.

[0027] Specifically, the bristles 2 are bonded to the surface of the substrate 1 .

[0028] Specifically, the power source may be an electric motor.

[0029] The bristles 2 include soft bristles 2a and hard bristles 2b. The soft bristles 2a and hard bristles 2b are alternately arranged along the circumference of the substrate 1, and the soft bristles 2a and hard bristles 2b are alternately arranged along the radial direction of the substrate 1. The soft bristles 2a and hard bristles 2b are not only alternately arranged along the circumference of the substrate 1, but also alternately arranged along the radial direction of the substrate 1, which can evenly cover the surface of the substrate 1, so that different areas work simultaneously during polishing, thereby improving the uniformity and effect of the overall polishing. The alternating arrangement can fully utilize the softness of the soft bristles 2a and the grinding force of the hard bristles 2b in the same polishing process to achieve a more uniform polishing effect, which can more effectively process surfaces of different materials. The alternating arrangement can reduce the wear of a single type of brush, thereby extending the service life of the entire brush, thereby reducing the replacement frequency and maintenance costs.

[0030] Specifically, the soft bristles 2 a and the hard bristles 2 b each have a plurality of clusters, and the soft bristles 2 a and the hard bristles 2 b are sequentially adhered to the surface of the substrate 1 .

[0031] Specifically, the soft bristles 2a are made of rubber filaments, and the hard bristles 2b are made of sisal. The rubber filaments have good flexibility and wear resistance, and can provide a better soft touch during the polishing process, reducing the risk of scratching soft surfaces. At the same time, the elasticity of the rubber filaments enables them to effectively adapt to irregular shapes when contacting the surface, ensuring comprehensive polishing. Sisal is a tough and durable natural fiber with a high grinding force, suitable for polishing hard surfaces. At the same time, the sisal bristles 2b can effectively remove surface dirt and scratches, improving the polishing effect. Both rubber filaments and sisal are relatively environmentally friendly materials, reducing dependence on synthetic materials, reducing the possibility of environmental pollution, and conforming to the trend of sustainable development.

[0032] The bristles 2 and the surface of the substrate 1 form an inclination angle of 50° to 70°. The inclination angle between the bristles 2 and the surface of the substrate 1 is within a suitable range, allowing the bristles 2 to closely adhere to the surface of the substrate 1 while ensuring that the contact pressure between the bristles 2 and the surface of the substrate 1 is evenly distributed, avoiding local overpressure or underpressure, taking into account both efficiency and service life, and ensuring the polishing effect.

[0033] At least two circles of guide holes 3 are provided on the substrate 1 along the circumferential direction, and the guide holes 3 of adjacent circles are staggered radially along the substrate 1. The guide holes 3 are arranged circumferentially along the substrate 1, and the guide holes 3 of each circle are staggered radially along the substrate 1, which reduces the risk of a single guide hole 3 being blocked. Even if a certain guide hole 3 fails due to dirt or material accumulation, the other guide holes 3 can still ensure the continuous flow of the polishing liquid, so as not to affect the polishing process, and can guide the flow of the polishing liquid more evenly, ensuring that the liquid is evenly distributed between the bristles 2, avoiding local liquid concentration or insufficiency. The bristles 2 can make full use of the polishing liquid during the polishing process, so that each contact area can be properly lubricated and ground, ensuring the polishing effect. When processing surfaces of different shapes or structures, the circumferential guide holes 3 can adapt to different flow requirements to ensure that a good polishing effect can be maintained on surfaces of complex shapes. Reasonably designed circumferential guide holes 3 can control the amount of polishing liquid used, avoid waste caused by liquid concentration, and thus improve economy and environmental protection.

[0034] When working, align the brush with and bring it close to the surface of the product. The power source drives the brush to rotate, the polishing liquid flows through the guide hole 3, and the bristles 2 polish the product. The bristles 2 include soft bristles 2a and hard bristles 2b. The soft bristles 2a make the bristles 2 have a certain softness, and the hard bristles 2b provide sufficient grinding force to ensure the polishing effect. An inclination angle is formed between the bristles 2 and the surface of the substrate 1. Even for complex or irregular grooves, the bristles 2 can effectively contact the edges, corners and walls of the grooves and fully polish them, ensuring the polishing effect while improving applicability. The setting of the guide hole 3 can effectively guide the flow of the polishing liquid and evenly distribute the polishing liquid. The reasonably set guide hole 3 can control the amount of polishing liquid used, avoid unnecessary waste, and improve economy.

[0035] Although this document frequently uses the terms substrate 1, bristles 2, soft bristles 2a, hard bristles 2b, guide holes 3, and mounting holes 4, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
