Description

Technical Field

[0001] The utility model particularly relates to a sand cleaning machine for graphite plates. Background Art

[0002] After the graphite plate is sintered, a layer of molding sand will form on its surface, which is usually removed by machinery and equipment. For example, the Chinese patent with application number 201821275268.6 discloses a graphite plate cleaning device, including a workbench and a cleaning box arranged on the workbench; the cleaning box is a rectangular shell structure, and the front of the cleaning box is open, and the two sides of the inner wall of the cleaning box are provided with slots for placing graphite plates, and the upper and lower parts of the graphite plate are symmetrically provided with dust removal components, and the dust removal components include a dust removal rod, a brush plate and a dust suction head fixed on the dust removal rod, and the brush plate and the dust suction head are close to the surface of the graphite plate, and the dust suction head is also connected to the suction pipe arranged inside the dust removal rod, and the two dust removal rods are connected by an intermediate plate, and the intermediate plate is connected to the lead screw transmission at the front of the cleaning box, and the lead screw is mounted on a transmission base fixed to the workbench.

[0003] In the above scheme, the graphite plate is inserted into the slot and cleaned with a brush. However, some graphite plates have different thicknesses, and it is difficult to change the size of the slot and the length of the brush in the above scheme. When the graphite plate is thicker, it may be difficult to insert it into the slot. When the graphite plate is thinner, the brush may be too short to contact the surface of the graphite plate. The above scheme is difficult to apply to graphite plates of different thicknesses. Utility Model Content

[0004] The utility model aims to provide a graphite plate sand cleaning machine which can clean the graphite plates with different thicknesses.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sand cleaning machine for graphite plates, comprising a conveyor belt for transporting graphite plate workpieces, a dust collecting hood with a downward opening is provided above the conveyor belt, the dust collecting hood extends along the width direction of the conveyor belt, and a space for the graphite plate workpiece to pass through is formed between the dust collecting hood and the conveyor belt; a rotatable brush roller is provided in the dust collecting hood, the outer wall of the brush roller is evenly covered with bristles for cleaning the molding sand on the surface of the graphite plate workpiece, the dust collecting hood is fixed on a lifting assembly, and the dust collecting hood passes through the lifting assembly so that the distance between the lower end of the dust collecting hood and the conveyor belt can be adjusted.

[0006] When the graphite plate workpiece is sanded, the operator places the graphite plate workpiece on the conveyor belt, and the conveyor belt conveys the graphite plate to the lower end of the dust collecting cover, and the brush roller rotates at the same time, and the bristles perform sand removal on the graphite plate workpiece. Among them, the brush roller can be any existing roller that can rotate and perform sand removal.

[0007] The dust hood is adjusted by a lifting assembly to make the distance between the lower end of the dust hood and the brush roller and the conveyor belt adjustable, so that it can be applied to graphite plates of different thicknesses. When the graphite plate is thicker, the distance between the dust hood and the conveyor belt is increased; when the graphite plate is thinner, the distance between the dust hood and the brush roller and the conveyor belt is reduced, so as to ensure that the bristles can contact the surface of the graphite plate. Among them, the lifting assembly can adopt any existing assembly that can realize the height adjustment of the dust hood and the brush roller, such as setting the dust hood at the lower end of the cylinder or the electric push rod.

[0008] This solution realizes the conveyance of the graphite plate by placing the graphite plate on the conveyor belt. The distance between the dust collecting hood and the brush roller and the conveyor belt can be adjusted by the lifting component, so that it can be suitable for sand cleaning of graphite plates of different thicknesses.

[0018] The clamping member can clamp the graphite plate workpiece, so that the friction between the graphite plate workpiece and the conveyor belt becomes larger, thereby preventing the graphite plate workpiece from slipping on the conveyor belt, so that the graphite plate workpiece will not slip when the brush roller cleans the molding sand on the surface of the graphite plate workpiece; at the same time, when the clamping member clamps the graphite plate workpiece, the two are in rolling contact, and the friction between the clamping member and the graphite plate workpiece is small, which will not affect the movement of the graphite plate workpiece. The clamping member can be a sphere or a roller.

[0019] Preferably, the pressing member is a roller, which can be fixed better than a ball.

[0020] Preferably, the pressing member is rotatably connected to one end of the rotating shaft, the other end of the rotating shaft is directly or indirectly fixed to a fixed block, and the height position of the rotating shaft on the fixed block is adjustable.

[0021] The height position of the rotating shaft is adjustable, so that the distance between the clamping member and the conveyor belt can be changed to adapt to graphite plate workpieces of different thicknesses. Among them, a number of fixing holes with different height positions can be opened on the fixed block, and the rotating shaft can be directly inserted into the fixing holes at different heights to achieve the height position adjustment of the rotating shaft; an electric push rod can also be set on the fixed block, and the driving direction of the electric push rod is vertical, and the rotating shaft is fixed to the output end of the electric push rod to achieve the height position adjustment of the rotating shaft; the rotating shaft can also be fixed on a rotating rod, and the rotating rod is rotated to achieve the height position adjustment of the rotating shaft, etc.

[0023] The rotating rod rotates on the fixed block to adjust the height position of the rotating shaft. After the height position of the rotating shaft is adjusted, the locking member is locked between the rotating rod and the fixed block, so that the rotating rod is fixed and the height position of the rotating shaft cannot be changed after adjustment. The locking member can be a combination of a bolt and a nut; or the bolt can be directly locked with the thread of the fixed block.

[0024] Preferably, a dust suction port opening upward is provided on the top of the dust collecting hood, and a dust suction device is connected to the dust suction port.

[0025] The dust suction port is connected to a dust suction device, so that the molding sand of the graphite plate workpiece can be sucked away by the dust suction device in time after being brushed away. The dust suction device can be any existing device that can be used for cleaning and dusting molding sand.
