Description

[0001] Technology

[0002] The invention relates to the technical field of material processing, and in particular to a new material grinding device. Background Art

[0003] New materials generally refer to structural materials with excellent performance and functional materials with special properties that have been recently developed or are being developed. Their material properties usually have better performance than traditional materials, such as higher strength, better toughness, lower density, etc. Therefore, they are widely used in various fields, such as aerospace, electronic information, environmental protection and energy conservation.

[0004] During the production or processing of new materials, burrs, scratches or other unevenness may occur on the surface. Through grinding, these defects can be removed to make the surface of the material smoother and more delicate. For new materials that have been welded, especially aluminum plates with a large number of welds such as hyperbolic aluminum veneers, grinding can significantly reduce or eliminate welding marks and improve the overall aesthetics of the product.

[0005] However, in the process of grinding new materials, grinding is usually done with abrasive tools. Long-term grinding may damage the abrasive tools and reduce the grinding efficiency. In particular, a large amount of impurities on the surface need to be removed during rough grinding, which increases the wear of the abrasive tools. The abrasive tools often need to be replaced during subsequent grinding, which reduces the grinding efficiency. Therefore, the present invention provides a new material grinding device that can improve the grinding efficiency, facilitate rough grinding of the surface of new materials, and extend the service life of the abrasive tools.

[0049] A coarse grinding mechanism for coarse grinding is provided above the grinding groove 2, and the coarse grinding mechanism includes a grinding disc 3, and a driving member is coaxially clamped on the top of the grinding disc 3, and the driving member is a motor 31. The two sides of the driving member are fixedly connected with a mounting frame 21 by bolts, and the mounting frame 21 is fixedly connected to the grinding groove 2; an injection chamber 32 is opened at the center of the grinding disc 3, and the injection chamber 32 is connected to a second pipe 51 for continuous air intake, and the end of the second pipe 51 away from the injection chamber 32 is fixedly connected to the mounting frame 21, and the end of the second pipe 51 away from the injection chamber 32 is connected to an air compressor (not shown in the figure), and the air compressor is a prior art and will not be repeated in this embodiment.

[0050] A reversing mechanism for changing the conveying direction of the new material block is provided between the first conveyor belt 1 and the grinding groove 2; the reversing mechanism includes a ball screw mechanism connected to the grinding groove 2, and the nut seat of the ball screw mechanism is fixedly connected with a moving block 23, and the moving block 23 and the arrangement direction of the grinding groove 2 are on the same horizontal plane.

[0051] The reversing mechanism also includes a mounting block 22 welded to the grinding groove 2, and the mounting block 22 is located at one end of the grinding groove 2 close to the first conveyor belt 1; the ball screw mechanism is located inside the mounting block 22, and the ball screw mechanism includes a power part welded to the mounting block 22. In this example, the power part is a servo motor, and a screw rod 26 is coaxially connected to the output end of the power part. The screw rod 26 rotates with the mounting block 22, the screw rod 26 slides with the moving block 23, and the moving block 23 slides with the mounting block 22.

[0052] The bottom of the moving block 23 is rotatably matched with a baffle 24, the baffle 24 is located on both sides of the moving block 23, a torsion spring (not shown in the figure) is connected between the baffle 24 and the moving block 23, one end of the torsion spring is fixedly connected to the baffle 24, and the other end of the torsion spring is fixedly connected to the moving block 23; and the side of the moving block 23 close to the baffle 24 is fixedly connected with a top block, and the side of the grinding groove 2 close to the mounting block 22 is provided with a matching groove 27; when the moving block 23 moves to the closest point to the grinding disc 3, the baffle 24 is against the top block and the new material block; when the moving block 23 moves to the farthest point from the grinding disc 3, the baffle 24 is located in the matching groove 27, and the baffle 24 is against the top block.

[0053] A storage tank 43 for collecting grinding powder of new material blocks is provided below the grinding tank 2. The storage tank 43 is connected to a powder conveying mechanism for conveying powder to the bottom of the moving block 23. When the new material block is conveyed to the grinding tank 2 via the first conveyor belt 1, the new material block is located below the moving block 23.

[0054] Among them, the powder conveying mechanism includes a support plate 4 located inside the grinding groove 2, and collecting grooves 41 are opened on both sides of the support plate 4, and the collecting grooves 41 are connected to the grinding groove 2; a filter screen 42 is provided between the accumulation groove 43 and the support plate 4, and the filter screen 42 is fixedly connected to the grinding groove 2; a powder conveying pump is provided in the accumulation groove 43, and the powder conveying pump is not shown in the figure. The powder conveying pump in this example is the prior art and is not described again; the input end of the powder conveying pump is connected to the accumulation groove 43, and the output end of the powder conveying pump is connected to the first tube 5, and the end of the first tube 5 away from the powder conveying pump is located above the grinding groove 2, and the first tube 5 is located on both sides of the moving block 23.

[0055] The specific implementation process is as follows:

[0056] Firstly, the supporting height of the first conveyor belt 1 and the grinding trough 2 is adjusted by the retractable telescopic rod, so that the staff can handle the equipment and the new material blocks in the grinding process, so as to facilitate manual operation; based on the height difference between the two ends of the first conveyor belt 1, the new material blocks can slide naturally into the grinding trough 2 due to their own gravity, and then the friction between the new material blocks and the first conveyor belt 1 can be reduced by the rotating conveying roller 11, so as to facilitate the movement of the new material blocks.

[0057] During the transmission process of the first conveyor belt 1, the screw rod 26 is driven to rotate by the power member to drive the moving block 23 on the screw rod 26 to reciprocate, so as to push the new material block in the grinding groove 2 to move in sequence; during the movement of the moving block 23 to the side close to the grinding disc 3, the baffle 24 is restricted by the top block so that the baffle 24 keeps limiting the new material block to push the new material block to move in the direction close to the grinding disc 3; and the new material block on the first conveyor belt 1 falls into the grinding groove 2 due to gravity to achieve continuous transportation of the new material block; during the reset process of the baffle 24 driven by the moving block 23, the baffle 24 is no longer restricted by the top block, so that the baffle 24 and the moving block 23 are rubbed against the new material block to achieve the grinding treatment of the surface of the new material block, and when the moving block 23 moves to the inside of the matching groove 27, the baffle 24 is no longer restricted by the new material block, and is reset based on the natural stretching of the elastic force of the torsion spring.

[0058] During the rough grinding process, since there is a lot of material to be removed, the friction contact between the grinding disc 3 and the material is more intense, which will not only generate a lot of heat, causing the abrasive tool to be thermally worn, but also generate a lot of dust. The remaining large particles of powder may form an inconsistent grinding path on the material surface, blocking the grinding track of the original grinding disc 3 and reducing the grinding efficiency. Therefore, the air is delivered to the jet chamber 32 by the air compressor, which is convenient for heat exchange between the air and the grinding disc 3, so that the air delivered by the air compressor through the second pipe 51 can continuously take away the heat of the grinding disc 3 during the grinding process, reducing the impact of high temperature during friction on the grinding disc 3; it is also convenient to remove the powder around the grinding disc 3 through the high-pressure airflow discharged from the jet chamber 32, reducing the impact of the powder generated after grinding on the subsequent grinding process of the new material block, so as to improve the grinding efficiency.

[0059] The powder after grinding by the grinding disc 3 falls into the collecting tank 41, and the large particles generated during the grinding process are filtered out by the filter 42 to reduce the blockage during the operation of the powder delivery pump to ensure the work efficiency. At the same time, the large particles are collected and processed by the filter 42 to ensure the particle size of the collected powder, so as to facilitate the recycling of the new material that can be recycled again. The powder is transported and processed by the powder delivery pump to be sprayed on the surface of the new material block to strengthen the friction between the new material block and the moving block 23, so as to facilitate the first grinding of the new material block; at the same time, the moving block 23 is driven by the ball screw mechanism to move, which can drive the new material block to contact with the grinding disc 3 to achieve rough grinding; at the same time, the moving block 23 rubs against the new material block during the resetting process to reduce the roughness of the surface of the new material block, thereby facilitating the subsequent grinding of the new material block, reducing the damage of the grinding disc 3 and improving the grinding efficiency.

[0060] At the same time, when the first tube 5 transports the powder to the top of the grinding tank 2, the greater the concentration of the powder particles in the powder discharged from the first tube 5, the heavier the weight. When the powder is discharged from the first tube 5, the heavy powder is not easily blown by the wind and falls to a distant place, so that the heavy powder is retained on the top of the new material block for extrusion and wear treatment, reducing the particle concentration in the powder, and facilitating the subsequent recycling of the powder.

[0061] Embodiment 2:

[0062] The difference from the first embodiment is that, in another embodiment, one end of the accumulation groove 43 close to the moving block 23 is lower than the other end of the accumulation groove 43 away from the moving block 23 .

[0063] The specific implementation process is as follows: through the height difference formed inside the accumulation tank 43, the powder inside the accumulation tank 43 can be collected and processed, and the powder conveying pump can be used to transport the powder.

[0064] Embodiment 3:

[0065] The difference from Example 2 is that a plurality of partitions are welded in the grinding tank 2 , the partitions are located between the support plate 4 and the filter screen 42 , and the partitions are located between adjacent collecting tanks 41 .

[0066] The specific implementation process is as follows: the powder dropped from the collecting tank 41 is collected separately by the partition to reduce the mixing of powder particles with different grinding degrees, so as to ensure the uniformity of the dust particles accumulated in the accumulation tank 43, and further ensure the smoothness of the powder delivery pump during operation.

[0067] Embodiment 4:

[0068] The difference from Example 3 is that an opening communicating with the outside is opened on one side of the jet chamber 32, and the opening is located on one side of the grinding disc 3. A temperature sensor is provided in the jet chamber 32, and the temperature sensor is electrically connected to the control panel.

[0069] The temperature sensor is used to measure the real-time heat value generated during the processing of the grinding disc 3 in real time, and send the real-time heat value to the control panel; the control panel is used to compare the real-time heat value with the set standard value. If the real-time heat value is greater than the standard value, a delay instruction is sent to the ball screw mechanism, and a power enhancement instruction is sent to the air compressor; if the real-time heat value is less than the standard value, a maintenance instruction is sent to the ball screw mechanism, and a maintenance instruction is sent to the air compressor.

[0070] For example, the real-time heat value is measured to determine whether the heat generated during the processing of the grinding disc 3 at the current time is close to the standard value, so as to control the movement rate of the moving block 23 driven by the ball screw mechanism, so as to extend the conveying time of the moving block 23 to convey the new material block, so as to facilitate the cooling of the grinding disc 3; at the same time, the air supply is strengthened through the air compressor to increase the flow rate of the air inside the jet chamber 32, so as to accelerate the removal of the heat of the grinding disc 3 by the air.

[0071] Embodiment 5:

[0072] The difference from Example 4 is that it also includes a laser irradiation mechanism, which includes a laser emitter 25 clamped to the moving block 23, and the laser emitter 25 is located on the side of the moving block 23 close to the grinding disc 3; a plurality of photoresistor sensors 33 are provided in the jet chamber 32, and the photoresistor sensors 33 are bonded to the grinding disc 3.

[0073] The photoresistor sensor 33 is used to measure the current change value when the laser emitter 25 is irradiated in real time, and send the current change value to the control panel; the control panel is used to record the corresponding continuous change time based on the current change value, and compare the continuous change time with the set standard time. If the continuous change time is greater than the standard time, a reminder instruction is sent to the outside world. In this embodiment, the outside world can be a mobile phone mobile terminal, a display screen, etc., and a power increase instruction is sent to the driving component; if the continuous change time is less than the standard time, a normal instruction is sent to the outside world, and a power reduction instruction is sent to the driving component.

[0074] For example, the laser emitter 25 continuously irradiates the photoresistor sensor 33 to determine the rotation speed of the grinding disc 3, so as to alert the outside world and judge whether it is necessary to adjust the grinding speed of the grinding disc 3 at the current time to ensure the rough grinding efficiency; at the same time, the power of the driving part is actively adjusted to ensure that the grinding disc 3 and the new material block rotate and rub within a certain range, overcome the friction force of the new material block on the grinding disc 3, and ensure the grinding efficiency.

[0075] The control panel is also used to enter and store the grinding speed corresponding to each new material type, and the grinding speed corresponds to a standard duration; when the continuous change time is greater than the standard duration, a reminder instruction is sent to the outside world, and a negative pressure adjustment instruction is sent to the air compressor; when the continuous change time is less than the standard duration, a normal instruction is sent to the outside world, and a maintenance instruction is sent to the air compressor.

[0076] For example, by entering different grinding speeds to determine whether the current grinding time is normal, when the continuous change time is greater than the standard time, the suction change of the air compressor is changed to adsorb the powder in the grinding process of the grinding wheel 3, so as to adsorb the powder into the jet chamber 32, so that the staff can determine the reason for the partial speed change through the powder to ensure the grinding accuracy.

[0077] Embodiment 6:

[0078] The difference from Example 5 is that it also includes a weight detection mechanism for measuring the weight of residual powder on the filter 42. In this embodiment, the weight detection mechanism is a pressure sensor (not shown in the figure), and the pressure sensor is located on both sides of the filter 42. The weight of the residual powder corresponding to the bottom of the conveying block is the first weight data, and the weight of the residual powder corresponding to the bottom of the grinding disc 3 is the second weight data.

[0079] The control panel is used to obtain the corresponding first comparison value and second comparison value based on the new material type, the first comparison value is the set comparison value of the residual powder weight corresponding to the bottom of the conveying block, and the second comparison value is the set comparison value of the residual powder weight corresponding to the bottom of the grinding disc 3; the first weight data is compared with the first comparison value, if the first weight data is greater than the first comparison value, a power increase instruction is sent to the driving component; if the first weight data is less than the first comparison value, a maintenance instruction is sent to the driving component; then the second weight data is compared with the second comparison value, if the second weight data is greater than the second comparison value, a power increase instruction is sent to the driving component, and a reminder instruction is sent to the outside world; if the second weight data is less than the second comparison value, a maintenance instruction is sent to the driving component.

[0080] For example, during the grinding process of a new material block, the uncertainty of the surface of the new material block and the wear and tear of the grinding disc 3 during the grinding process and the changes in the speed control may cause the particle size of the powder after grinding to change. By comparing the weight of the residual powder on the filter 42, the current grinding situation can be reconfirmed to determine whether the current grinding situation matches the situation during the grinding of the new material; so as to adjust the power of the drive component and remind the staff to ensure the grinding efficiency.

[0081] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
