Description

Technical Field

[0001] This invention relates to the field of grinding wheel technology, and more specifically, to a grinding wheel with a dust removal structure. Background Technology

[0002] A grinding wheel machine is a common piece of equipment used to sharpen various cutting tools and implements. It mainly consists of a machine base, a grinding wheel, a motor, and other accessories. During grinding, the high-speed friction between the grinding wheel and the workpiece generates a large amount of dust and large-diameter metal or grinding wheel particles. To improve the working environment, existing grinding wheel machines are typically equipped with dust collection devices. A fan draws dust-laden gas into a dust collection box, where it is filtered before being discharged or recirculated.

[0003] For example, Chinese patent application CN105290972B discloses a dust removal grinding wheel machine, belonging to the field of work technology. It solves the problem of insufficient types and varieties of existing dust removal grinding wheel machines. The dust removal grinding wheel machine includes a dust removal box and a grinding wheel machine. The body of the grinding wheel machine is fixed on the top surface of the dust removal box. A partition is fixed inside the dust removal box to divide the inner cavity of the dust removal box into a dust removal chamber and an exhaust chamber. The dust removal chamber is provided with a dust removal drawer and a dust removal filter plate. The dust removal drawer is located above the dust removal filter plate, and the dust inlet is directly opposite the cavity of the dust removal drawer. An air passage is opened on the partition. An exhaust hole is opened on the side plate and / or bottom plate of the exhaust chamber. A fan is provided in the exhaust chamber, and the air inlet of the fan is connected to the air passage. Sand, sparks, and dust generated during polishing are drawn into the dust collection box through the dust inlet by the airflow generated by the fan. Since the sand and sparks are relatively heavy, most of them fall naturally into the dust collection drawer. After the dust is filtered by the dust collection filter plate, the clean air is discharged from the exhaust port through the air vents, the fan, and the exhaust chamber.

[0004] However, existing dust removal devices for grinding wheels have the following problems in actual use: large-diameter flying particles generated during the operation of the grinding wheel are mixed with dust. The dust can be circulated with the airflow of the fan and intercepted by the filter screen, but large-diameter flying particles with high kinetic energy will directly impact and embed into the mesh of the filter screen, causing the filter screen to become clogged. Therefore, we propose a grinding wheel with a dust removal structure. Summary of the Invention

[0005] This invention provides a grinding wheel machine with a dust removal structure. This grinding wheel machine with a dust removal structure can solve the problem mentioned in the background art that when the grinding wheel machine is working, large-diameter flying particles and dust are mixed together. The dust can be circulated with the airflow of the fan and intercepted by the filter screen, but large-diameter flying particles with high kinetic energy will directly hit and embed into the mesh of the filter screen, causing the filter screen to be blocked.

[0006] To achieve the above objectives, this solution provides a grinding wheel machine with a dust removal structure, including a base, on which a grinding assembly and a dust removal assembly are provided. The grinding assembly includes a grinding wheel, which is rotatably mounted on the base. A motor for driving the grinding wheel to rotate is installed on the base. The dust removal assembly includes a dust collection box, which is installed on the side of the grinding wheel. The dust collection box is a semi-enclosed box, and the open part of the dust collection box is positioned corresponding to the grinding wheel. Multiple impact plates are installed inside the dust collection box and are arranged horizontally at equal intervals. The impact plates are made of stainless steel, and the distance between adjacent impact plates is less than 2 cm. A corrugated pipe mounting seat is provided on the side of the dust collection box away from the grinding wheel, and a filter screen is installed inside the corrugated pipe mounting seat. During dust removal, the flying particles generated by the grinding wheel impact the side wall of the impact plate and fall into the dust collection box.

[0007] Optionally, the grinding assembly further includes a drive shaft, which is rotatably mounted on the machine base. One end of the drive shaft is connected to the grinding wheel, and the other end of the drive shaft and the output shaft of the motor are both provided with synchronous pulleys, and a synchronous belt is connected between a pair of synchronous pulleys.

[0008] Optionally, the bottom surface of the dust collector is provided with an inclined plate, and a slag discharge port is opened at the bottom end of the dust collector. The slag discharge port is located at the bottom end of the inclined plate, and a bottom cover is detachably installed on the slag discharge port. After the flying particles generated by the grinding wheel hit the impact plate, they fall onto the inclined plate.

[0009] Optionally, the dust collection box has an open end equipped with a support plate for placing processed materials. The support plate is located at the bottom of the grinding wheel. A movable plate is provided on the inclined plate. The bottom end of the movable plate is hinged to the inclined plate, and the top end of the movable plate is located at the bottom of the support plate.

[0010] Optionally, a pair of spring plates are installed at the bottom of the impact plate, with the other end of the spring plates intermittently contacting the surface of the inclined plate.

[0011] Optionally, a cylinder is installed on the inner wall of the dust collection box, and the bottom end of the cylinder extension rod is rounded. After the cylinder is started, the end of the cylinder extension rod strikes the surface of the movable plate. A buffer pad is provided on the surface of the movable plate. The buffer pad is an elastic rubber pad and is located directly below the cylinder extension rod.

[0012] Optionally, a limit block is installed on the inner wall of the dust collection box, and after the movable plate is reset, the surface of the movable plate abuts against the limit block.

[0013] Optionally, a filter plate is installed inside the dust collection box. The filter plate is a stainless steel perforated plate and is installed on the side of the impact plate away from the grinding wheel.

[0014] Optionally, the movable plate is provided with a vertical plate, and the vertical plate is equipped with protrusions. There are multiple protrusions, and the multiple protrusions are distributed vertically and equally. The bottom end of the filter plate is provided with a horizontal bar, which is correspondingly provided with the vertical plate.

[0015] Optionally, the surface of the protrusion is set as an arc-shaped surface. When the movable plate moves, the protrusion intermittently contacts the crossbar. After the protrusion passes the crossbar, the filter plate vibrates.

[0016] Through the above technical solution, the grinding wheel machine with dust removal structure provided by this solution is used as follows: after the disordered large-diameter flying particles generated by the grinding wheel enter the dust removal box, they collide with the surface of the impact plate, thereby consuming a large amount of kinetic energy, preventing the flying particles from moving further with the airflow, and the large-diameter particles fall directly into the bottom of the dust removal box, preventing blockage of the subsequent filter structure. Furthermore, large-diameter flying particles fall onto the movable plate. As the cylinder starts periodically, the cylinder piston rod strikes the movable plate, and the movable plate vibrates with the help of the spring plate, gradually sliding the accumulated flying particles to the slag discharge port for easy cleaning later. Moreover, when the movable plate vibrates, the contact between the protrusion and the crossbar will cause the filter plate to vibrate synchronously, thereby shaking off the flying particles intercepted on the filter plate, reducing the manual maintenance cycle and increasing the practicality of the device.

[0017] Other features and advantages of this solution will be described in detail in the following detailed implementation section. Attached Figure Description

Detailed Implementation

[0027] To make the aforementioned objectives, features, and advantages of this solution more apparent and understandable, the specific embodiments of this solution are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this solution. However, this solution can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this solution. Therefore, this solution is not limited to the specific embodiments disclosed below.

[0028] In the description of this solution, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this solution and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this solution. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

[0029] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0030] According to some embodiments of this solution, a grinding wheel machine with a dust removal structure is provided, for reference. Figures 1 to 8 As shown, the grinding wheel with dust removal structure includes a base 101, the bottom of which is fixed to the ground or workbench by anchor bolts to ensure the stability of the equipment during operation. The bottom surface of the base 101 can also be equipped with vibration damping rubber pads to further reduce the vibration transmitted to the ground. The base 101 is equipped with grinding components and dust removal components.

[0031] The dust collection assembly includes a dust collection box 301, which is formed by sheet metal welding and fixedly mounted on the base 101 on the side of the grinding wheel 201 by bolts or brackets. The wall thickness of the dust collection box 301 is determined according to actual usage requirements, and cold-rolled steel plates with a thickness of 1.5 mm to 3 mm are usually selected to ensure structural strength while taking into account the overall weight control of the equipment.

[0032] The dust collection box 301 is set as a semi-enclosed box, and the opening of the dust collection box 301 is set to correspond to the grinding wheel 201 so that the operator can insert the workpiece for grinding, while preventing flying particles from splashing outward. The edges of the opening are ground to remove burrs, so as to prevent the operator from being scratched by sharp edges when picking up and putting down the workpiece.

[0033] The dust collector 301 is equipped with multiple impact plates 305, which are arranged horizontally and equidistantly. The impact plates 305 are made of stainless steel plates and are fixed to the inner wall of the dust collector 301 by welding or slots. The distance between adjacent impact plates 305 is less than 2 cm.

[0034] Therefore, after the high-speed airflow carrying flying particles enters the dust collector 301, it is forced to repeatedly change its flow direction in the narrow channel. Due to its large inertia, the large-diameter flying particles are difficult to follow the airflow and turn sharply, thus frequently hitting the surface of the impact plate 305. After transferring the kinetic energy it carries to the impact plate 305, it loses its forward momentum and finally falls downward under the action of gravity.

[0035] In practice, the surface of the impact plate 305 can also be sandblasted or brushed to increase surface roughness and further improve the interception efficiency of flying particles.

[0036] Specifically, a corrugated pipe mounting seat 303 is provided on the side of the dust collector 301 away from the grinding wheel 201. The corrugated pipe mounting seat 303 is connected to the dust collector 301 via a flange or thread and is used to connect the corrugated pipe of the external exhaust fan. The diameter of the corrugated pipe mounting seat 303 is designed to match the air volume parameters of the exhaust fan to ensure smooth airflow and reduce pipeline resistance loss. A filter screen 314 is snapped or bolted into the corrugated pipe mounting seat 303. The filter screen 314 is used to intercept medium-sized particles that penetrate the area of ​​the impact plate 305, serving as a fine filtration barrier. During dust removal, the external exhaust fan generates negative pressure, which draws the flying particles and dust generated by the grinding wheel 201 into the dust collector 301. After the disordered large-sized flying particles enter the dust collector 301, they collide with the surface of the impact plate 305, thereby consuming a large amount of kinetic energy and preventing the flying particles from moving further with the airflow. The large-sized flying particles fall directly into the interior of the dust collector 301, preventing blockage of the subsequent filter screen 314 structure.

[0037] It should be noted that the grinding assembly includes a grinding wheel 201, which is rotatably mounted on a machine base 101. A motor 202 is mounted on the machine base 101 to drive the grinding wheel 201. Specifically, the motor 202 is fixedly mounted on the machine base 101 via a motor bracket and bolts. The power and speed of the motor 202 can be selected and matched according to the diameter of the grinding wheel 201 and the grinding requirements; typically, a three-phase asynchronous motor is used. The grinding assembly also includes a drive shaft 205, which is rotatably mounted on the machine base 101 via bearings and bearing housings. The bearings are deep groove ball bearings or angular contact ball bearings to adapt to high-speed rotation conditions, and the bearing housings are filled with grease. It is equipped with a dustproof sealing ring. One end of the drive shaft 205 is connected to the grinding wheel 201 through a flange and a locking nut. During installation, attention should be paid to the fit between the flange and the end face of the grinding wheel 201, and an elastic gasket should be placed between them to avoid the grinding wheel 201 from breaking due to uneven clamping force. The other end of the drive shaft 205 and the output shaft of the motor 202 are both fixed with synchronous pulleys 203 by key connection. A synchronous belt 204 is connected between a pair of synchronous pulleys 203. The synchronous belt 204 is a toothed rubber belt or a polyurethane belt, which has the advantages of smooth transmission, low noise, and no need for additional lubrication. Anti-slip plates are set on both sides of the synchronous pulleys 203 to prevent the synchronous belt 204 from slipping during operation. Compared to the traditional V-belt drive, the synchronous belt drive can effectively avoid slippage and ensure that the speed of the grinding wheel 201 and the output speed of the motor 202 are precisely synchronized. After the motor 202 starts, it drives the transmission shaft 205 and the grinding wheel 201 to rotate at high speed through the synchronous belt 204 and the synchronous pulley 203 to realize the grinding operation. A protective cover is also installed on the machine base 101. The protective cover covers the upper part of the grinding wheel 201, exposing only the grinding area below, to prevent injury to the operator in case the grinding wheel breaks accidentally. The material of the protective cover is preferably transparent polycarbonate plate, which not only ensures the safety protection function, but also does not affect the operator's observation of the grinding process.

[0038] Specifically, the bottom surface of the dust collector 301 is welded with an inclined plate 306, which has a certain inclination angle (e.g., 30°-45°). The bottom end of the dust collector 301 is provided with a slag discharge port, which is located at the bottom end of the inclined plate 306. A bottom cover 307 is detachably installed on the slag discharge port by means of threads or buckles. A sealing rubber ring can also be set on the bottom cover 307 to prevent air leakage during negative pressure operation. Operators can periodically unscrew the bottom cover 307 to collect and remove the accumulated metal slag. The operation is simple and does not affect the normal operation of the equipment. After the flying particles generated by the grinding wheel 201 hit the impact plate 305, they fall on the inclined plate 306 and gather towards the slag discharge port under the action of gravity.

[0039] The dust collection box 301 has a support plate 302 for placing the processed materials installed at its open end by bolts. It is located at the bottom of the grinding wheel 201. The length and width of the support plate 302 are determined according to the size range of common workpieces to ensure that the workpiece has sufficient support area during grinding and to reduce operator fatigue. A movable plate 304 is provided on the inclined plate 306. The bottom end of the movable plate 304 is hinged to the inclined plate 306 by a hinge or pin, and the top end of the movable plate 304 is located at the bottom of the support plate 302. The movable plate 304 can swing back and forth around the hinge point within a certain angle range.

[0040] Specifically, a pair of spring plates 312 are installed at the bottom of the impact plate 305 by screws. The other end of the spring plate 312 hangs freely and intermittently contacts the surface of the inclined plate 306. The spring plate 312 is made of spring steel, which has good elasticity and fatigue life. Its free end maintains slight contact with the surface of the inclined plate 306 in its natural state. When the movable plate 304 vibrates, the spring plate 312 will undergo elastic deformation and repeatedly hit the surface of the inclined plate 306, helping to loosen the fine particles attached to the inclined plate 306 and make them slide down the inclined surface. The inner wall of the dust collector 301 is equipped with a cylinder 310 by a cylinder bracket and bolts. The bottom end of the cylinder 310 telescopic rod is rounded. After the cylinder 310 is started, the end of the cylinder 310 telescopic rod hits the surface of the movable plate 304.

[0041] To prevent rigid impacts from damaging the movable plate 304 or generating excessive noise, a buffer pad 313 is fixed to the surface of the movable plate 304 by adhesive or screws. The buffer pad 313 is an elastic rubber pad, and the buffer pad 313 is located directly below the telescopic rod of the cylinder 310.

[0042] The inner wall of the dust collector 301 is welded or bolted with a limit block 315. After the movable plate 304 is reset, the surface of the movable plate 304 abuts against the limit block 315 to limit the reset limit position of the movable plate 304.

[0043] Large-diameter fly particles fall onto the movable plate 304. As the cylinder 310 is periodically activated, the piston rod of the cylinder 310 strikes the movable plate 304, and the telescopic rod of the cylinder 310 strikes the movable plate 304 in an intermittent telescopic manner, causing the movable plate to oscillate back and forth around the hinge point. The movable plate 304 vibrates under the cooperation of the spring plate 312, gradually sliding the accumulated fly particles to the slag discharge port, which is convenient for later opening of the bottom cover 307 for cleaning. This process realizes the self-cleaning function of the bottom of the dust collector 301, effectively avoiding the problem of fly particles accumulating in large quantities at the bottom of the box, which affects the dust removal efficiency and airflow.

[0044] Through the above technical solution, when the grinding wheel machine with dust removal structure provided by this solution is in use, the disordered large-diameter flying particles generated by the grinding wheel 201 enter the dust collection box 301 and collide with the surface of the impact plate 305, thereby consuming a large amount of kinetic energy and preventing the flying particles from moving further with the airflow. The large-diameter particles fall directly into the bottom of the dust collection box 301, preventing blockage of the subsequent filter screen 314 structure. Moreover, the large-diameter flying particles fall onto the movable plate 304. As the cylinder 310 is periodically started, the piston rod of the cylinder 310 impacts the movable plate 304. The movable plate 304 vibrates under the cooperation of the spring plate 312, gradually sliding the accumulated flying particles to the slag discharge port, which is convenient for later cleaning.

[0045] In some implementations of this solution, reference is made to Figure 4 As shown, a filter plate 308 is slidably installed in the dust collection box 301 via a guide rail or slot. The filter plate 308 is a stainless steel mesh plate, and its mesh size is selected according to the dust particle size to be intercepted, so as to achieve a balance between filtration accuracy and air volume. The filter plate 308 is installed on the side of the impact plate 305 away from the grinding wheel 201.

[0046] A vertical plate 311 is welded or integrally formed on the movable plate 304. A protrusion 316 is installed on the vertical plate 311. Multiple protrusions 316 are provided and distributed vertically and equally. A horizontal bar 309 is welded or bolted to the bottom end of the filter plate 308. The horizontal bar 309 is correspondingly set with the vertical plate 311. The surface of the protrusion 316 is set as an arc surface. When the movable plate 304 moves, the protrusion 316 and the horizontal bar 309 intermittently contact each other. When the protrusion 316 passes the horizontal bar 309, the filter plate 308 resets under its own gravity or elastic deformation and vibrates.

[0047] When the movable plate 304 vibrates, the contact between the protrusion 316 and the crossbar 309 will cause the filter plate 308 to vibrate synchronously, thereby shaking off the flying particles and dust intercepted on the filter plate 308, reducing the manual maintenance cycle and increasing the practicality of the device.

[0048] It should be noted that, in practical implementation, the start and stop of cylinder 310 can be periodically controlled via a time relay or PLC controller. For example, cylinder 310 can be set to operate every 5-10 minutes, with each operation consisting of 3-5 strokes, to ensure the regular cleaning effect of the movable plate 304 and filter plate 308. The PLC controller can also automatically adjust the cleaning frequency based on the cumulative operating time of the equipment. For example, it can appropriately shorten the cleaning interval under continuous high-intensity operation conditions and appropriately extend the cleaning interval under intermittent light-load operation conditions, achieving intelligent adaptive control. In addition, a throttle valve can be installed on the air intake circuit of cylinder 310 to adjust the extension speed and impact force of the telescopic rod to adapt to the cleaning requirements of different particle sizes and accumulation amounts.

[0049] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0051] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
