Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a belt wheel position adjustment device for a belt grinding machine. Background Technology

[0002] Belt grinding machines are widely used for surface processing of materials such as metal, wood, and plastic. The belt wheel is one of the most crucial components of a belt grinding machine, responsible for providing power to the belt during the grinding process. With continuous technological advancements, belt grinding machines have increasingly higher requirements for precision and efficiency. As a key component, the belt wheel position adjustment device needs to maintain a certain level of accuracy and flexibility during operation to ensure stable belt operation and uniform grinding results.

[0003] Currently, the position of the abrasive belt wheel is not easily adjustable during grinding, which may lead to problems such as belt misalignment, uneven grinding, excessive wear, and belt damage, thus affecting processing accuracy and efficiency. Furthermore, when the abrasive belt wheel needs to be replaced or repaired, it is inconvenient to disassemble, increasing maintenance time and reducing work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a belt wheel position adjustment device for a belt grinding machine.

[0005] This utility model is achieved using the following technical solution: a belt wheel position adjustment device for a belt grinding machine, comprising a fixed plate, a support leg fixedly connected to the bottom of the fixed plate, a universal wheel fixedly connected to the bottom of the support leg, and a main body fixedly connected to the top of the fixed plate, and further comprising: an adjustment mechanism, the adjustment mechanism comprising an adjustment housing fixedly connected to the right side of the main body, a first motor fixedly connected to the inner wall of the right side of the adjustment housing, a bidirectional threaded rod fixedly connected to the output end of the first motor, an adjustment block threadedly connected to the outer side of the bidirectional threaded rod, a transmission shaft rotatably connected inside the adjustment block, a first sliding plate rotatably connected to the outer side of the transmission shaft, and a first bevel gear fixedly connected to the outer side of the transmission shaft.

[0006] The above technical solution allows the first motor to be started to drive the bidirectional threaded rod to rotate, thereby adjusting the distance between the adjusting blocks, which in turn adjusts the distance between the transmission shafts, and finally adjusts the distance between the sanding belt wheels. At the same time, the transmission shaft can be moved inside the main body by the first sliding plate.

[0007] As a further improvement to the above solution, there are two adjusting blocks, and the two adjusting blocks are respectively threaded to the outside of the bidirectional threaded rod in different thread directions, and the first sliding plate is slidably connected to the inside of the fixed plate.

[0008] As a further improvement to the above solution, a power mechanism is provided on the top of the fixing plate. The power mechanism includes a power housing fixedly connected to the right side of the main body. A second motor is fixedly connected to the inner wall of the right side of the power housing. A convex shaft is fixedly connected to the output end of the second motor. A sliding sleeve is slidably connected to the outside of the convex shaft. A second bevel gear is fixedly connected to the outside of the sliding sleeve. A connecting block is rotatably connected to the outside of the sliding sleeve.

[0009] The above technical solution allows the second motor to be started to drive the cam shaft to rotate, causing the second bevel gear to mesh with the first bevel gear, thus providing power for the rotation of the transmission shaft. At the same time, when the transmission shaft moves, the connecting block can drive the sliding sleeve on the cam shaft to move synchronously.

[0010] As a further improvement to the above scheme, the second bevel gear meshes with the first bevel gear, the transmission shaft is rotatably connected inside the connecting block, and the adjusting block is fixedly connected to the front of the connecting block.

[0011] As a further improvement to the above solution, a quick-release mechanism is provided on the top of the fixing plate. The quick-release mechanism includes a fixing block fixedly connected to the front of the drive shaft, a spring fixedly connected inside the fixing block, a limit post fixedly connected inside the fixing block, a pressing shell slidably connected to the outside of the limit post, a locking block fixedly connected to the outside of the pressing shell, a grooved block sleeved on the outside of the fixing block, a sanding belt wheel fixedly connected to the front of the grooved block, and a sanding belt drivingly connected to the outside of the sanding belt wheel.

[0012] The above technical solution allows the sanding belt wheel to be fixed by engaging the locking block and the grooved block on the outside of the pressing shell, thus connecting the sanding belt wheel to the fixing block. At the same time, the spring can automatically rebound after the pressing shell is pressed.

[0013] As a further improvement to the above solution, the spring is fixedly connected to the bottom of the pressing shell, the pressing shell is slidably connected to the inside of the fixing block, three sanding belt wheels are provided, and the sanding belt drive is connected to the outside of the three sanding belt wheels.

[0014] As a further improvement to the above solution, an angle adjustment mechanism is provided on the top of the fixed plate. The angle adjustment mechanism includes a telescopic outer shell fixedly connected to the right side of the fixed plate. A hydraulic rod is fixedly connected to the inner wall of the right side of the telescopic outer shell. A sliding block is fixedly connected to the left end of the hydraulic rod. A rotating column is rotatably connected inside the sliding block. A second sliding plate is rotatably connected to the outside of the rotating column.

[0015] Through the above technical solution, the hydraulic rod can push the sliding block to move inside the main body, thereby moving the rotating column and adjusting the angle of the sanding belt. At the same time, the second sliding plate can make the rotating column move inside the main body.

[0016] As a further improvement to the above solution, the sliding block is slidably connected to the bottom inner wall of the main body, and the second sliding plate is slidably connected inside the main body.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention provides dual functions of tension and angle adjustment through its adjustable and power mechanisms. Especially when adjusting the tension of the abrasive belt, the first motor drives a bidirectional threaded rod to adjust the position of the adjusting block, making the tension adjustment of the abrasive belt faster and more stable, meeting the requirements of different grinding tasks. Simultaneously, the sliding block controlled by a hydraulic rod adjusts the angle of the abrasive belt wheel, improving processing flexibility, adapting to various workpiece shapes, and enhancing processing accuracy and efficiency.

[0019] This utility model features a quick-release mechanism that allows for easy disassembly of the slotted block and removal of the sanding wheel when replacement or maintenance is required. The spring-loaded design ensures rapid response of the device, reducing labor intensity during parts replacement. During installation, simply align the device with the fixing block and slip the slotted block on to secure it, simplifying the replacement process and improving work efficiency.

[0034] The second bevel gear 305 meshes with the first bevel gear 207, the drive shaft 205 is rotatably connected inside the connecting block 306, and the adjusting block 204 is fixedly connected to the front of the connecting block 306.

[0035] The top of the fixed plate 1 is provided with a quick release mechanism 4. The quick release mechanism 4 includes a fixed block 401 fixedly connected to the front of the drive shaft 205. A spring 402 is fixedly connected inside the fixed block 401. A limit post 403 is fixedly connected inside the fixed block 401. A pressing shell 404 is slidably connected to the outside of the limit post 403. A locking block 405 is fixedly connected to the outside of the pressing shell 404.

[0039] The implementation principle of the belt wheel position adjustment device for a belt grinder in this embodiment is as follows: During operation, the device is first moved to a suitable position using the caster wheel 12. After reaching the suitable position, the second motor 302 is started to drive the cam shaft 303 to rotate, thereby causing the cam shaft 303 to drive the sliding sleeve 304 to rotate, which in turn causes the second bevel gear 305 to rotate. Through the meshing of the second bevel gear 305 and the first bevel gear 207, the transmission shaft 205 is driven to rotate, causing the transmission shaft 205 to drive the fixed block 401 to rotate, which in turn causes the belt wheel 407 to drive the belt 408 to rotate. At this time, the material to be ground can be ground. If the tension of the belt 408 needs to be adjusted during use, the first motor 202 can be started to drive the bidirectional threaded rod 203 to rotate, causing the adjusting blocks 204 threaded to the outside of different thread directions of the bidirectional threaded rod 203 to move, thereby adjusting the distance between the adjusting blocks 204. Through the movement of the adjusting blocks 204, the transmission shaft 205 is driven to rotate. The first sliding plate 206 moves within the main body 13, thereby adjusting the distance between the sanding belt wheels 407 and thus the tension of the sanding belt 408. When it is necessary to adjust the angle of the sanding belt 408, the hydraulic rod 502 can be activated to move the sliding block 503 along the bottom inner wall of the main body 13, allowing the rotating column 504 to move within the main body 13 via the second sliding plate 505, which in turn moves the sanding belt wheels 407 to adjust the angle of the sanding belt 408. When the sanding belt wheel 407 needs to be replaced or repaired, the pressing shell 404 can be pressed to disengage the locking block 405 from the grooved block 406, and the grooved block 406 can be removed to complete the separation. At this time, the pressing shell 404 will spring back under the action of the spring 402 to complete the removal. During installation, press the pressing shell 404 to align the grooved block 406 with the position of the fixing block 401, then put the grooved block 406 on the outside of the fixing block 401, and release the pressing shell 404 so that the locking block 405 limits the grooved block 406 to complete the installation.
