[0002] Belt sander is a common machining tool, which consists of motor, bearing, pulley, sanding belt and other parts. Belt sander has a high-speed rotating sanding belt, which can grind, polish and polish the surface of various materials. Belt sander has the characteristics of simple structure, easy operation and high efficiency, and is widely used in metal processing, furniture manufacturing, automobile maintenance and other fields.

[0003] In the long-term operation of the existing belt sander, the power consumption will increase when the interface between the belt and the workpiece is too large. In addition, a large amount of wood chips or iron chips are easy to adhere to the belt during sand polishing, and the belt is easy to heat up, thereby shortening the service life of the belt. However, replacing the belt requires removing the grinding wheel or the drive motor from the machine tool processing position for replacement, which prolongs the working time and reduces production efficiency.

[0004] Therefore, a polishing belt machine is proposed. Utility Model Content

[0005] The utility model aims to provide a polishing belt machine to solve the problem that when replacing a belt, a grinding wheel or a driving motor needs to be removed from a machine tool processing position for replacement, which prolongs the working time and reduces production efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A polishing belt machine comprises a workbench, wherein a transmission mechanism is arranged on the outer wall surface of the workbench, a downward supporting leg is fixedly connected to the bottom of the workbench, a side panel is arranged on the top rear side of the workbench, a polishing machine is arranged on the front side of the side panel, a belt is arranged inside the polishing machine, an upper and lower symmetrical movable blocks are arranged inside the belt, threaded holes and through holes are respectively provided on the left and right sides inside the movable blocks, mirror-imaged top panels are fixedly connected to the sides of the movable blocks away from each other, placement grooves are provided on the sides of the top panels away from each other, a relaxing component with a lifting function is provided inside the side panel, and a cleaning component with a cleaning function is provided on the front side of the workbench.

[0008] Furthermore, the relaxation component includes a rectangular hole opened inside the side plate, a first stepper motor is fixedly connected to the left side of the inner bottom end of the rectangular hole, a rotating shaft is fixedly connected to the output end of the first stepper motor, and threaded structures with opposite rotation directions are respectively provided at the upper and lower ends of the outer wall of the rotating shaft, and a fixing rod is fixedly connected to the right side of the inner bottom end of the rectangular hole.

[0009] Furthermore, the movable blocks are respectively threadedly connected to the threaded structures with opposite rotation directions through threaded holes, and the movable blocks are movably connected to the outer wall surface of the fixed rod through the through holes.

[0010] Furthermore, the top rear side of the workbench is fixedly connected with equidistantly arranged hydraulic rods, and the bottom of the side plate is fixedly connected to the top of the hydraulic rods.

[0011] Furthermore, the cleaning component includes a rectangular groove opened on the front side of the top of the workbench, and limiting holes are opened on the left and right sides of the rectangular groove. A tooth plate is movably connected inside the rectangular groove, and a second stepper motor is fixedly connected to the front center of the workbench, and the output end of the second stepper motor is fixedly connected to a second rotating shaft, and the output end of the second rotating shaft is fixedly connected to a gear, and the gear and the tooth plate are meshed with each other. A vertical pole is arranged on the left side of the interior of the rectangular groove, and a brush is fixedly connected to the side wall of the vertical pole.

[0012] Furthermore, a rectangular block is fixedly connected to the rear right end of the tooth plate, a limiting groove is provided inside the rectangular block, springs are fixedly connected to the left and right sides of the bottom end of the vertical rod, and the output ends of the springs are fixedly connected to limiting blocks arranged in a mirror image, and the limiting blocks are respectively located on the left and right sides of the limiting groove.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. When the belt needs to be replaced, the utility model drives the movable block to move upward and downward respectively through the relaxation component until the upper end makes the belt located inside the placement groove. The belt loses tension through the stretching of the movable block, and the belt can be taken out and replaced with a new one. The belt replacement requires the grinding wheel or the driving motor to be removed from the processing position of the machine tool for replacement, which prolongs the working time and reduces the production efficiency. The driving cleaning component cleans the dust on the top of the transmission mechanism to prevent the dust from falling into the inside of the belt.

[0015] 2. The utility model sets a relaxation component. First, the external controller is started, and then the first stepper motor is started.

The movable block pulls the belt through the top plate and the placement groove, causing the belt to lose tension and the belt can be easily replaced.

[0016] 3. The utility model sets a cleaning component. When it is necessary to clean the dust on the top of the transmission mechanism, the external controller is started, the second stepper motor is started, and the second shaft is driven to rotate through the output end. The second shaft drives the gear to rotate, and the gear then drives the toothed plate meshing with it to slide to the left. The toothed plate drives the vertical rod to move to the left through the limiting hole, and the vertical rod then drives the brush to clean the top of the transmission mechanism. When cleaning is not needed, the limiting blocks are manually pinched close to each other, the spring is deformed and contracted by the pressure, and then the vertical rod is held and moved upward, so that the bottom of the vertical rod and the limiting block are separated from the inside of the limiting groove, so that the brush is separated from the top of the transmission mechanism.
