Description

Technical Field

[0001] This utility model relates to the field of abrasive belt technology, and in particular to a magnetically attached abrasive belt. Background Technology

[0002] Abrasive belts are commonly used tools for surface grinding and polishing, and are widely used in woodworking, metal processing, automotive repair, and other fields. They work by using friction between the abrasive and the surface to remove unevenness, oxide layers, or rust, improving the smoothness and precision of the workpiece and often achieving high-quality processing results.

[0003] Traditional abrasive belts typically consist of an abrasive layer, a substrate, and a binder. The abrasive layer determines the belt's cutting performance and durability, the substrate provides support and strength, and the binder secures the abrasive to the substrate, ensuring stability and longevity.

[0004] The inconvenience of using traditional abrasive belts lies in their cumbersome replacement and installation process. Due to variations in belt size and usage conditions, manual adjustment or reinstallation is required each time a belt is replaced, increasing both time and difficulty. Furthermore, the heat generated by prolonged friction during use leads to performance degradation of traditional belts, and even affects machining quality if not replaced in a timely manner. This complex operation and inconvenient maintenance not only reduce work efficiency and increase production costs but also pose potential safety risks to equipment and operators. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a magnetically attached abrasive belt, which aims to improve the problem that traditional abrasive belts accumulate heat during use due to long-term friction, leading to performance degradation and even affecting processing quality if not replaced in time.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a magnetically attached abrasive belt, comprising:

[0007] A flexible baseband, made of a flexible material, is used as a base carrier for abrasive belts;

[0008] A magnetic layer, the sidewall of which is fixedly connected to one side surface of the flexible base tape, is used to remove the grinding surface;

[0009] An abrasive layer, the sidewall of which is fixedly connected to the sidewall of the magnetic layer, a magnetic matrix is ​​provided inside the abrasive layer, and abrasive particles are provided on the outer wall of the abrasive layer for direct contact with the workpiece;

[0010] Multiple edge reinforcing strips are fixedly connected to the upper and lower surfaces of the flexible base strip.

[0011] As a further description of the above technical solution:

[0012] The magnetic layer is a flexible magnetic sheet made by mixing and pressing permanent magnet powder with rubber binder, and is used to disassemble the abrasive layer.

[0013] As a further description of the above technical solution:

[0014] The flexible baseband is provided with anti-slip components on its sidewalls to prevent slippage during grinding.

[0015] As a further description of the above technical solution:

[0016] The anti-slip component includes anti-slip textures, and a plurality of the anti-slip textures are formed on the sidewall of the flexible baseband.

[0017] As a further description of the above technical solution:

[0018] The abrasive layer is provided with a positioning component on its sidewall to prevent displacement of the abrasive layer.

[0019] As a further description of the above technical solution:

[0020] The positioning component includes multiple positioning protrusions, and the sidewalls of the multiple positioning protrusions are fixedly connected to the sidewall of the abrasive layer.

[0021] As a further description of the above technical solution:

[0022] The magnetic layer has multiple positioning grooves inside, which engage with positioning protrusions to restrict the displacement of the abrasive layer.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the magnetic layer and the magnetic substrate of the abrasive layer are firstly attracted to each other, so that the abrasive layer can be quickly disassembled and replaced. Compared with the cumbersome process of manual adjustment or reinstallation of traditional sanding belts, the maintenance operation is greatly simplified and the replacement time is saved. The positioning protrusions of the abrasive layer and the positioning grooves of the magnetic layer engage with each other, effectively limiting the displacement of the abrasive layer during the grinding process, ensuring grinding accuracy, and avoiding the impact of the abrasive layer sliding on the processing quality.

[0025] 2. In this utility model, the overall strength of the sanding belt is enhanced by the edge reinforcing strip, reducing tearing caused by friction at the edge and extending its service life; the anti-slip texture on the side wall of the flexible base belt enhances the friction between the sanding belt and the grinding equipment, preventing slippage during grinding, improving operational safety, solving the problems of inconvenient replacement and easy slippage of traditional sanding belts, adapting to different curved surface grinding needs, and improving work efficiency and processing stability.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 One embodiment of this utility model is a magnetically attached abrasive belt, comprising:

[0033] Flexible baseband 1, made of flexible material, is used as the base carrier of the abrasive belt;

[0034] Magnetic layer 2, the sidewall of magnetic layer 2 is fixedly connected to one side surface of flexible base tape 1, for disassembling the grinding surface, so that the abrasive layer 3 can be quickly replaced after wear, reducing the time cost of replacement operation and improving the continuity of grinding operation;

[0035] Abrasive layer 3 has its sidewalls fixedly connected to the sidewalls of magnetic layer 2. The sidewalls of abrasive layer 3 are connected to the sidewalls of magnetic layer 2 by the attraction force of magnetic layer 2. The abrasive particles on the outer wall directly contact the workpiece surface, thereby removing burrs, oxide layers and other defects on the workpiece surface through friction, achieving grinding and polishing of the workpiece, and improving the smoothness and precision of the workpiece surface. Abrasive layer 3 and magnetic layer 2 are magnetically connected, achieving the effect of quick assembly and disassembly of abrasive layer 3 without tools, which makes it easy to replace the abrasive layer 3 with the corresponding grit size according to different workpiece materials.

[0036] Multiple edge reinforcing strips 4 are fixedly connected to the upper and lower surfaces of the flexible base belt 1. These edge reinforcing strips 4 enhance the structural strength of the edges of the flexible base belt 1, thereby preventing tearing of the abrasive belt due to repeated stress during high-speed grinding, extending the overall service life of the abrasive belt, and reducing the cost of frequent belt replacements. The magnetic layer 2 is a flexible magnetic sheet made by mixing and pressing permanent magnet powder with a rubber binder. Its function is to generate a stable magnetic attraction force to fix and remove the abrasive layer 3. This is a common application based on the properties of magnetic materials and is common knowledge, so it will not be elaborated further here. The sidewall of the flexible base belt 1 is provided with anti-slip components. These anti-slip components prevent slippage during grinding, and the positioning protrusions 6 cooperate with the positioning grooves 5. The engagement motion prevents the abrasive layer 3 from shifting laterally during grinding, ensuring the accuracy of the contact position between the grinding particles and the workpiece. The anti-slip component includes anti-slip textures 7, which work in conjunction with the contact surface between the flexible base belt 1 and the grinding equipment to improve the stability of the connection between the abrasive belt and the equipment. Multiple anti-slip textures 7 are formed on the side wall of the flexible base belt 1. The side wall of the abrasive layer 3 is provided with positioning components to prevent displacement of the abrasive layer 3. The positioning components include multiple positioning protrusions 6, which are fixedly connected to the side wall of the abrasive layer 3. Multiple positioning grooves 5 are formed inside the magnetic layer 2, which engage with the positioning protrusions 6 to restrict the displacement of the abrasive layer 3.

[0037] Working principle: During grinding, the anti-slip texture 7 on the side wall of the flexible base belt 1 enhances the friction between the sanding belt and the grinding equipment, preventing the sanding belt from slipping. Meanwhile, the multiple edge reinforcing strips 4 fixed on the upper and lower surfaces of the flexible base belt 1 enhance the overall strength of the sanding belt, preventing the edges from tearing due to friction. The abrasive particles on the outer wall of the abrasive layer 3 directly contact the workpiece surface, and the workpiece is ground through friction. When the abrasive layer 3 is worn, the magnetic adsorption properties of the magnetic layer 2 can be used to easily remove the abrasive layer 3 and replace it with a new one, achieving rapid maintenance.
