Description

Technical Field

[0001] This utility model relates to the field of grinding and shaping technology, specifically to a high-efficiency flat sander for grinding and shaping. Background Technology

[0002] A flat sander is a mechanical device used for sanding and polishing flat surfaces. It is widely used in woodworking, metal processing, and furniture manufacturing industries. As the requirements for surface smoothness and gloss in industries such as furniture, electronics, and automobiles continue to increase (e.g., high-end furniture finishes need to achieve a mirror-like effect), the low efficiency and poor consistency of traditional manual sanding have become increasingly prominent. This has spurred the development of mechanized sanding equipment. Industrialized mass production demands improved sanding efficiency and reduced labor costs. Flat sanders, through standardized operating procedures, can quickly process large-area workpieces (such as wood panels and metal sheets), meeting the needs of assembly line production.

[0003] Existing flatbed sanders require manual adjustment of equipment parameters when processing workpieces of different thicknesses. Furthermore, when the machine sands the workpiece, debris is generated and splashes onto the worktable, requiring subsequent cleaning, slowing down processing efficiency, and potentially interfering with the accuracy of subsequent processing. Summary of the Invention

[0004] This utility model provides a high-efficiency flat sander for grinding and shaping. The housing design can effectively collect debris, thus preventing debris from splashing and making cleaning inconvenient. The combined use of components such as cylinders, telescopic rods, and the first fixed plate can effectively adjust for different thicknesses.

[0005] To achieve the above objectives, a high-efficiency flat sander for grinding and shaping is provided, comprising a main body, a housing fixedly connected to the upper surface of the main body, dust curtains fixedly installed on both sides of the housing, a grinding mechanism and a cleaning mechanism fixedly connected inside the housing, a clamping mechanism fixedly installed on the inner side wall, a dust suction mechanism fixedly connected to the top of the main body, an air pump fixedly connected to the upper surface of the main body, a filter assembly fixedly connected to the side of the upper surface of the main body near the transmission pipe, a transmission pipe fixedly connecting the air pump and the filter assembly, a circular roller movably installed on one side of the housing, a transmission belt sleeved on the circular roller, a first motor sleeved on one end of the transmission belt, and a fixing plate fixedly connected to the lower surface of the first motor. The housing effectively prevents debris from splashing, the dust curtains on both sides of the housing prevent debris from splashing during workpiece loading and unloading, the grinding mechanism can effectively grind workpieces of different thicknesses, and the air pump, transmission pipe, and filter assembly effectively collect debris.

[0006] According to the aforementioned high-efficiency flat sander for grinding and shaping, the cleaning mechanism includes a limiting block, a second spring, a connecting rod, a second fixing plate, and a cleaning roller. The lower surface of the limiting block is fixedly connected to the upper surface of the connecting rod. The cleaning mechanism can effectively perform preliminary cleaning of the ground workpiece, and the cleaning roller is equipped with a flexible brush for effective cleaning.

[0007] According to the aforementioned high-efficiency flat sander for grinding and shaping, the second spring is sleeved and installed on the outer wall of the connecting rod. The lower surface of the connecting rod is fixedly connected to the upper surface of the second fixed plate, and a cleaning roller is movably connected to the lower part of the second fixed plate. Under the action of the second spring, workpieces of different thicknesses can be effectively cleaned.

[0008] According to the aforementioned high-efficiency flat sander for grinding and shaping, the grinding mechanism includes a cylinder, a telescopic rod, a first fixed plate, a grinding roller, a second motor, and a third motor. The cylinder is fixedly mounted on the upper surface of the housing, and the telescopic rod is fixedly connected to the output end of the cylinder. The cylinder and telescopic rod on the grinding assembly can effectively adjust the height, thereby facilitating the grinding of workpieces of different thicknesses.

[0009] According to the aforementioned high-efficiency flat sander for grinding and shaping, the lower surface of the telescopic rod is fixedly connected to the upper surface of the first fixed plate. Two sets of grinding rollers are movably connected below the first fixed plate. A second motor is fixedly connected to one end of each grinding roller, and a third motor is fixedly connected to the side of the grinding roller closest to the second motor. Two grinding rollers are arranged below the first fixed plate, and each grinding roller has a motor at one end, facilitating the provision of power to the grinding rollers.

[0010] According to the aforementioned high-efficiency flat sander for grinding and shaping, the clamping mechanism includes a groove, a first spring, a slider, and a rubber roller. The groove is formed on the side wall inside the housing, and the slider is movably installed within the groove. This clamping mechanism effectively clamps and fixes the workpiece, thereby facilitating its processing.

[0011] According to the aforementioned high-efficiency flat sander for grinding and shaping, a first spring is fixedly connected above the slider, and a rubber roller is movably connected to the side wall of the slider. The rubber roller moves under the action of the conveyor belt, and the rubber roller and the slider are movably connected. Rubber rollers of different thicknesses will apply different pressures to the first spring, and at the same time, the elastic force of the first spring will react on the workpiece, thereby fixing the workpiece and facilitating grinding by the grinding mechanism.

[0012] The beneficial effects of this utility model are as follows: by setting up mechanisms such as cylinders, telescopic rods and first fixed plates in the grinding mechanism, it is possible to effectively adjust workpieces of different thicknesses; the setting of the box body can effectively prevent debris from flying; and the setting of the dust collection mechanism can effectively collect debris and prevent it from accumulating.

[0024] The cleaning mechanism 6 includes a limiting block 601, a second spring 602, a connecting rod 603, a second fixing plate 604, and a cleaning roller 605. The lower surface of the limiting block 601 is fixedly connected to the upper surface of the connecting rod 603. The second spring 602 is sleeved and installed on the outer wall of the connecting rod 603. The lower surface of the connecting rod 603 is fixedly connected to the upper surface of the second fixing plate 604. The cleaning roller 605 is movably connected to the lower part of the second fixing plate 604. The polishing mechanism 4 includes a cylinder 401, a telescopic rod 402, a first fixing plate 403, a polishing roller 404, a second motor 405, and a third motor 406. The cylinder 401 is fixedly installed on the upper surface of the housing 2. The output end of the cylinder 401 is fixedly connected to the telescopic rod 402.

[0025] The lower surface of the telescopic rod 402 is fixedly connected to the upper surface of the first fixed plate 403. Two sets of grinding rollers 404 are movably connected below the first fixed plate 403. One end of the grinding roller 404 is fixedly connected to the second motor 405. The side of the grinding roller 404 near the second motor 405 is fixedly connected to the third motor 406. The pressing mechanism 10 includes a slide groove 101, a first spring 102, a slider 103 and a rubber roller 104. The slide groove 101 is opened on the side wall inside the housing 2. The slider 103 is movably installed in the slide groove 101. The first spring 102 is fixedly connected above the slider 103. The rubber roller 104 is movably connected to the side wall of the slider 103.

[0026] Working principle: The workpiece to be ground is placed on the upper surface of the conveyor belt and enters through the inlet. The dust curtain 3 at the inlet effectively prevents debris from splashing. After the workpiece enters the housing 2, the change in workpiece thickness causes a change in the distance between the rubber roller 104 and the conveyor belt surface. The upper end of the first spring 102 is fixedly connected to the upper surface inside the slide groove 101, and the lower end is fixedly connected to the slider 103. The slider 103 and the rubber roller 104 drive the first spring 102 to slide inside the slide groove 101 according to the thickness of the workpiece, which compresses the first spring 102. The elastic force of the first spring 102 then reacts to the workpiece, thereby fixing the workpiece. An external air source starts the cylinder 401. The telescopic rod 402 on the lower surface of the cylinder 401 drives the first fixed plate 4. 03. Vertical movement is performed, and the second motor 405 and the third motor 406 are started by the external power supply, which facilitates the grinding of workpieces of different thicknesses. Then, it enters the cleaning mechanism 6. Similar to the clamping mechanism 10, it adjusts itself according to the thickness of the workpiece. The second fixed plate 604 and the cleaning roller 605 are movably connected. When the conveyor belt moves the workpiece, the cleaning roller 605 slides off the workpiece to perform preliminary cleaning. The cleaning roller 605 is equipped with multiple sets of small flexible brushes. The air pump 502 is started by the external power supply. The filter assembly 503, the air pump 502 and the box 2 are interconnected through the transmission pipe 501. Under the action of the air pump 502, the debris inside the box 2 is sucked out to prevent the accumulation of debris. The filter assembly 503 can effectively collect and filter debris.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
