[0002] In industrial processing, abrasive belts are a commonly used grinding tool, widely used in surface grinding and polishing of materials such as metal and wood. Traditional abrasive belts have a relatively simple structure, which easily leads to problems such as abrasive shedding, low grinding efficiency, and poor heat dissipation during grinding, making it difficult to meet the needs of high-precision and high-efficiency processing. Therefore, it is necessary to develop a composite structure superhard abrasive belt. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figures 1-4 The diagram shown is a structural schematic of an embodiment of a combined structure superhard abrasive belt according to this utility model. Please refer to [link / reference]. Figures 1-4 This paper provides a detailed introduction to a composite structure superhard abrasive belt.

[0023] A composite structure superhard abrasive belt includes a base belt 100. A plurality of longitudinal protrusions 101 are uniformly distributed along the length of the upper surface of the base belt 100. The upper edges of the longitudinal protrusions 101 transition in an arc shape on both sides, and grooves 102 are formed between adjacent longitudinal protrusions 101. The longitudinal protrusions 101 enhance the structural strength of the base belt 100, making it less prone to deformation during high-speed operation. Furthermore, the arc shape of the upper edges of the longitudinal protrusions 101 can guide the flow of debris during grinding, preventing debris accumulation from affecting the grinding effect.

[0024] The bottom of the groove 102 is provided with a plurality of drainage holes 103, which penetrate the base belt 100. During the use of the abrasive belt, especially in wet grinding conditions, the drainage holes 103 can drain the coolant or wastewater generated during grinding in time, preventing liquid from remaining on the abrasive belt and affecting the cutting performance of the abrasive. At the same time, it can also prevent the abrasive belt from slipping due to water accumulation, ensuring the stability of the grinding operation.

[0025] The top of the longitudinal protrusion 101 is provided with a dovetail groove 104 along its length. The top of the longitudinal protrusion 101 is adapted to the shape of the groove of the dovetail groove 104. A superhard abrasive layer 105 is provided on the top of the dovetail groove 104. The special shape of the dovetail groove 104 can make the superhard abrasive layer 105 more firmly embedded in the longitudinal protrusion 101, effectively preventing the abrasive from falling off under the action of grinding force and improving the service life of the abrasive belt. At the same time, since the abrasive layer is distributed on the top of the protrusion, it can exert a more complete grinding effect when in contact with the workpiece, thereby improving grinding efficiency.

[0026] The surface of the superhard abrasive layer 105 is formed by serrated abrasive strips 106, with the tips of the serrations facing the direction of movement of the abrasive belt. The serrated abrasive strips 106 increase the contact points between the superhard abrasive layer 105 and the workpiece, making the grinding sharper and enabling the rapid removal of excess material from the workpiece surface, thus improving machining accuracy. Moreover, with the tips of the serrations facing the direction of movement, they can also play a certain role in chip separation during grinding, further optimizing the chip removal effect.

[0027] The lower surface of the base belt 100 is provided with multiple transverse reinforcing ribs 107 at equal intervals along the width direction. The cross-section of the transverse reinforcing ribs 107 is triangular. The transverse reinforcing ribs 107 can enhance the transverse tensile strength of the base belt 100, prevent the abrasive belt from tearing when subjected to force in the width direction, and ensure the reliability of the abrasive belt in high-speed and high-load grinding operations. The triangular cross-section can provide good support strength and reduce the amount of material used, thereby reducing costs.

[0028] The lower surface of the base belt 100 between adjacent transverse reinforcing ribs 107 is provided with anti-slip texture 108; the anti-slip texture 108 can increase the friction between the sanding belt and the drive wheel and driven wheel, prevent the sanding belt from slipping during transmission, ensure the stable operation of the sanding belt, and thus ensure the continuity and precision of grinding.

[0029] The base belt 100 has inwardly rolled edges 109 on both sides. The inwardly rolled edges 109 are arc-shaped and their thickness is less than the thickness of the main body of the base belt 100. The arc-shaped inwardly rolled edges 109 can prevent the sanding belt from scratching operators or damaging surrounding equipment during installation and use. The thinner inwardly rolled edges 109 reduce the weight of the sanding belt edge without affecting the overall strength, which is conducive to maintaining the balance of the sanding belt when running at high speed, reducing vibration, and improving grinding quality.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
