Description

Technical Field

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

[0002] In the field of industrial processing, belt abrasive wheels are widely used as important grinding tools. Traditional belt abrasive wheels usually adopt an integral structure, with the abrasive belt and wheel body fixedly connected. When the abrasive belt wears out and needs to be replaced, the entire belt abrasive wheel often needs to be disassembled and replaced, which is not only cumbersome and wasteful of time and effort, but also increases production costs.

[0003] Existing technologies have the following problems:

[0004] While some existing sanding belt designs feature replaceable sanding belts, most suffer from complex connection structures and inconvenient assembly and disassembly. For example, some use bolt fixing, requiring tools for operation and resulting in low replacement efficiency. Others use snap-fit ​​connections, but these snaps are prone to damage, leading to poor connection stability. During high-speed rotation of the sanding belt, there is a potential safety hazard of the sanding belt falling off, affecting processing quality and production safety.

[0005] To address these shortcomings, we proposed a replaceable abrasive belt wheel. Utility Model Content

[0006] The purpose of this invention is to provide a replaceable abrasive belt wheel to overcome the shortcomings of existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a replaceable sanding belt wheel, comprising a sanding belt wheel support body and a replaceable sanding belt body. The surface of the sanding belt wheel support body is provided with a mating groove, and a mating block is inserted into the mating groove. One end of the mating block is fixedly connected to one side surface of the replaceable sanding belt body. The surface of the mating block is provided with a locking groove, and a locking block is used in conjunction with the locking groove. A connecting rod is provided through the surface of the sanding belt wheel support body, and a pull block is installed at one end of the connecting rod. A groove is provided on the surface of the sanding belt wheel support body at the position corresponding to the pull block. A storage groove is provided inside the sanding belt wheel support body, and the storage groove is used in conjunction with the locking block. A spring is sleeved inside the sanding belt support body outside the connecting rod.

[0008] Preferably, the surface of the abrasive belt wheel support body has a central hole.

[0009] Preferably, there are multiple replaceable sanding belt bodies, and the multiple replaceable sanding belt bodies are arranged in a ring array on the surface of the sanding belt wheel support.

[0010] Preferably, the volume of the storage slot is larger than the volume of the locking block.

[0011] Preferably, the end of the locking block near the locking groove is an inclined surface.

[0012] Preferably, the volume of the groove is larger than the volume of the pull block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention achieves the fixation of the replaceable sanding belt body by inserting the mating block into the mating groove and the locking block into the locking groove. Specifically, when the replaceable sanding belt body needs to be installed, simply align the mating block with the mating groove and insert it. Then, under the elastic force of the spring, push the pull block, which moves the locking block through the connecting rod, allowing the locking block to insert into the locking groove, thus completing the fixation. The operation is simple and quick, requiring no tools. When the sanding belt is worn and needs to be replaced, simply pull the pull block to remove the locking block from the locking groove, and then pull the replaceable sanding belt body out of the mating groove. This greatly improves replacement efficiency, reduces downtime, and lowers production costs. At the same time, this connection method has a stable structure, and the tight fit between the mating block and the mating groove, and between the locking block and the locking groove, effectively prevents the replaceable sanding belt body from falling off during the high-speed rotation of the sanding wheel, improving safety and stability during processing and ensuring processing quality.

[0023] Please refer to Figure 1-3 A replaceable abrasive belt wheel includes an abrasive belt wheel support body 1 and a replaceable abrasive belt body 3. The surface of the abrasive belt wheel support body 1 is provided with a mating groove 4, and a mating block 5 is inserted into the mating groove 4. One end of the mating block 5 is fixedly connected to one side surface of the replaceable abrasive belt body 3. The surface of the mating block 5 is provided with a locking groove 6, and a locking block 8 is used in conjunction with the locking groove 6. A connecting rod 9 is provided through the surface of the abrasive belt wheel support body 1, and a pull block 11 is installed at one end of the connecting rod 9. A groove 10 is provided on the surface of the abrasive belt wheel support body 1 at the position corresponding to the pull block 11. A storage groove 7 is provided inside the abrasive belt wheel support body 1, and the storage groove 7 is used in conjunction with the locking block 8. A spring 12 is sleeved inside the abrasive belt wheel support body 1 outside the connecting rod 9.

[0024] In use, the sanding belt is installed on a drive device, such as a motor shaft, through the center hole 2 of the sanding belt support to achieve power transmission. When installing the replaceable sanding belt body 3, the mating block 5 on one side is aligned with the mating groove 4 on the surface of the sanding belt support 1 and inserted along the guide direction to initially fix the replaceable sanding belt body 3 to the outer periphery of the sanding belt support 1. At this time, the locking block 8 inside the sanding belt support 1, under the action of the spring 12, is pushed by the connecting rod 9 to slide the inclined end of its end close to the locking groove 6 along the surface of the mating block 5 until it falls completely into the locking groove 6, forming a mechanical lock and completing the installation. The spring 12, sleeved on the outside of the connecting rod 9, continuously provides locking force to ensure stable connection during high-speed rotation. When changing the sanding belt, the pull block 11 in the outer groove 10 of the sanding belt support 1 is pulled outward. The pull block 11, through the connecting rod 9, drives the locking block 8 to overcome the spring 12's elasticity, exit from the locking groove 6, and retract into the storage groove 7. Inside, since the volume of the storage groove 7 is larger than the volume of the locking block 8, it provides space for the locking block 8 to move. At this time, the replaceable sanding belt body 3 can be pulled out from the fitting groove 4. When disassembling and replacing the new sanding belt, repeat the above installation steps.

[0025] In this implementation scheme: the surface of the abrasive belt wheel support 1 is provided with a central hole 2 for the abrasive belt wheel support.

[0026] Specifically, the center hole 2 of the abrasive belt wheel support is used to connect with the shaft of the drive equipment, such as by key connection or interference fit, so that the abrasive belt wheel can rotate synchronously with the drive equipment to transmit the torque required for grinding.

[0027] In this embodiment, there are multiple replaceable sanding belt bodies 3, and the multiple replaceable sanding belt bodies 3 are arranged in a ring array on the surface of the sanding belt wheel support 1.

[0028] Specifically, multiple replaceable abrasive belt bodies 3 are arranged in a ring array on the surface of the abrasive belt wheel support 1 to evenly distribute the grinding force, avoid vibration caused by uneven force on the abrasive belt wheel, and at the same time increase the grinding area and improve processing efficiency. Each replaceable abrasive belt body 3 is independently detachable. When part of the abrasive belt is worn, only the abrasive belt at the corresponding position needs to be replaced, without replacing the whole belt, thus reducing the cost of use.

[0029] In this implementation scheme: the volume of the storage slot 7 is larger than the volume of the locking block 8.

[0030] Specifically, the storage slot 7 provides ample space for the locking block 8 to move, ensuring that the locking block 8 can retract smoothly under the action of the pull block 11, avoiding interference with the internal structure of the sanding wheel support 1, while also accommodating slight displacement of the locking block 8 during movement, ensuring smooth disassembly and assembly operations.

[0031] In this implementation scheme: the end of the locking block 8 near the locking groove 6 is an inclined surface.

[0032] Specifically, the beveled design allows the locking block 8 to automatically slide into the locking groove 6 after contacting the mating block 5 during installation, reducing insertion resistance and improving installation convenience. At the same time, when the sanding wheel rotates, the beveled structure can generate a wedge-tightening effect, enhancing locking reliability and preventing the locking block 8 from popping out due to centrifugal force.

[0033] In this embodiment, the volume of the trough 10 is greater than the volume of the pull block 11.

[0034] Specifically, the groove 10 provides space for the pull block 11 to move, making it easy for the operator to pull or push the pull block 11. At the same time, it avoids frictional interference between the pull block 11 and the surface of the sander wheel support 1, ensuring that the locking block 8 can achieve stable locking and unlocking actions through the connecting rod 9.

[0035] Working principle: In use, the sanding belt is installed on a drive device such as a motor shaft through the center hole 2 of the sanding belt support to achieve power transmission. When installing the replaceable sanding belt body 3, the mating block 5 on one side is aligned with the mating groove 4 on the surface of the sanding belt support 1 and inserted along the guide direction to initially fix the replaceable sanding belt body 3 to the outer periphery of the sanding belt support 1. At this time, the locking block 8 inside the sanding belt support 1, under the action of the spring 12, is pushed by the connecting rod 9 to slide the inclined end of its end close to the locking groove 6 along the surface of the mating block 5 until it falls completely into the locking groove 6, forming a mechanical lock and completing the installation. The spring 12 is sleeved on the outside of the connecting rod 9 to continuously provide locking force to ensure stable connection during high-speed rotation. When changing the sanding belt, the pull block 11 in the outer groove 10 of the sanding belt support 1 is pulled outward. The pull block 11 drives the locking block 8 to overcome the spring 12's elasticity, exit from the locking groove 6, and retract into the storage groove 7. Inside, since the volume of the storage groove 7 is larger than the volume of the locking block 8, it provides space for the locking block 8 to move. At this time, the replaceable sanding belt body 3 can be pulled out from the fitting groove 4. When disassembling and replacing the new sanding belt, repeat the above installation steps.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
