[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example
[0024] Please refer to Figure 1-4 An electric punch grinder according to this embodiment includes a base plate 1, a support frame 2 fixedly installed on the top of the base plate 1, a top seat 3 fixedly installed on the top of the support frame 2, a grinder body 4 fixedly installed on the top of the top seat 3, grinding wheels 5 rotatably connected to both sides of the front of the grinder body 4, and a waste collection device 6 fixedly installed at the top front end of the top seat 3.
[0025] The waste collection device 6 includes a collection hopper 61 and a cleaning assembly 62. The collection hopper 61 is fixedly installed at the front center of the grinder body 4, and the cleaning assembly 62 is fixedly installed at the lower front end of the grinder body 4. The outer side of the cleaning assembly 62 is fitted and connected to the bottom of the grinding wheel 5. A filter assembly 63 is fixedly installed at the bottom of the collection hopper 61, and a suction fan 64 is fixedly installed at the bottom of the filter assembly 63. The input end of the suction fan 64 is connected to the bottom of the collection hopper 61. When this electric punch grinder is running, the waste collection device 6 works in conjunction with the grinder body 4 to achieve efficient waste processing. After the grinder body 4 is started, the grinding wheels 5 on both sides rotate at high speed to grind the punch. At this time, the waste collection device 6, located at the front center of the grinder body 4, collects the waste. The collection bucket 61, in conjunction with the negative pressure generated by the bottom suction fan 64, forms a powerful suction field, quickly drawing the debris generated during the grinding process into the collection bucket 61. At the same time, the cleaning assembly 62, fixed to the lower front of the grinder body 4, fits tightly against the bottom of the grinding wheel 5. As the grinding wheel 5 rotates, the cleaning assembly 62 continuously scrapes its surface, promptly removing the adhering debris and preventing secondary splashing of debris. This ensures that the debris can be successfully captured by the collection bucket 61. The debris drawn into the collection bucket 61 then enters the bottom filter assembly 63, where it is intercepted and separated by the filter screen 634. Solid debris is retained and collected, while the filtered air is discharged through the suction fan 64, achieving efficient collection of waste and air purification, ensuring a clean working environment and stable equipment operation.
[0026] Please refer to Figures 1-3The cleaning assembly 62 includes a support plate 621, which is fixedly connected to the lower front end of the grinder body 4. Inclined plates 622 are fixedly installed on both sides of the top of the support plate 621. A cleaning brush 623 is fixedly connected to the top of the inclined plates 622. The outer side of the cleaning brush 623 is fitted to the bottom of the grinding wheel 5. The overall shape of the inclined plates 622 and the support plate 621 is Y-shaped. The side shape of the collection hopper 61 is an inverted isosceles trapezoid. A front baffle 65 is fixedly installed at the front end of the top of the collection hopper 61, and side baffles 66 are fixedly connected to both sides of the top of the collection hopper 61. When this electric punch grinder is working, the cleaning assembly 62 and the collection hopper 61 cooperate to collect debris. When the grinding wheel 5 rotates at high speed for grinding, the support plate 621 fixed to the lower front end of the grinder body 4 remains stable, and its top is Y-shaped. The Y-shaped inclined plates 622 support the cleaning brush plate 623 at a suitable height, ensuring that the outer side of the cleaning brush plate 623 fits tightly against the bottom of the grinding wheel 5. As the grinding wheel 5 rotates, the cleaning brush plate 623 continuously brushes its surface, peeling off the debris adhering to the grinding wheel 5. The collection hopper 61 is an inverted isosceles trapezoid, a shape design that helps to expand the collection range. Its top front baffle 65 and side baffle 66 prevent debris from splashing in all directions. At the same time, the suction fan 64 operates to generate negative pressure, forming suction in the collection hopper 61. The peeled debris and the debris generated directly during the grinding process are quickly drawn into the collection hopper 61 by the suction and their own gravity, and separated by the bottom filter assembly 63. This efficiently completes the debris collection work during the grinding process, ensuring a clean working environment and normal equipment operation.
[0027] Please refer to Figures 1-2 and Figure 4The filter assembly 63 includes a collection box 631, which is fixedly installed at the bottom of the collection hopper 61. The top of the collection box 631 is connected to the bottom of the collection hopper 61. An opening 632 is provided on one side of the collection box 631. A collection drawer 633 is slidably connected inside the collection box 631. A filter screen 634 is fixedly installed at the bottom of the collection drawer 633. A sealing plate 635 is fixedly installed on the outside of the collection drawer 633, closing the outside of the opening 632. Mounting plates 636 are fixedly installed on both the front and back of the sealing plate 635. A mounting screw 637 is threaded to the end of the mounting plate 636. The end of the mounting screw 637 passes through the mounting plate 636 and connects to the outside of the collection box 631. The filter screen 634 has a V-shaped cross-section. A groove 638 is provided in the middle of the outer side of the sealing plate 635. During use, when the electric punch grinder is running, the debris collected by the collection hopper 61... Under the negative pressure of the suction fan 64, the debris enters the fixedly connected collection box 631 through the bottom of the collection hopper 61. The debris entering the collection box 631 falls into the internal collection drawer 633. The V-shaped filter screen 634 at the bottom of the drawer filters and separates the debris. Air passes through the filter screen 634 and is discharged by the suction fan 64, while the debris is intercepted by the filter screen. Because the filter screen 634 is V-shaped, the debris slides to both sides along the inclined surface of the filter screen and eventually falls to the bottom of both sides of the collection drawer 633, avoiding accumulation and clogging of the filter screen and ensuring filtration efficiency. When it is necessary to clean the collected debris or replace the filter screen 634, the operator can apply force through the groove 638 on the outside of the sealing plate 635, loosen the installation screw 637, and pull out the sealing plate 635, which will drive the collection drawer 633 to slide out from the opening 632 of the collection box 631 for convenient maintenance. After maintenance, the operation can be reversed to reinstall, ensuring that the filter assembly 63 continues to operate efficiently.
[0028] Operating principle and advantages: This device achieves dual optimization of debris collection and equipment maintenance during the grinding process through the systematic design of the waste collection device 6. When the grinding operation starts, the suction fan 64 operates synchronously. Utilizing the principle of negative pressure, a high-efficiency suction channel is formed through the collection box 631 and the collection hopper 61, which quickly sucks the debris generated during grinding into the filter component 63. The flow guiding design of the collection hopper 61 ensures that the debris is quickly and directionally transported, avoiding scattering. At the same time, when the grinding machine body 4 is running, the cleaning brush 623 installed on the inclined plate 622 on the top of the support plate 621 is closely attached to the surface of the grinding wheel 5. As the grinding wheel 5 rotates at high speed, the brush continuously performs dynamic cleaning, effectively removing the adhering debris. This not only improves the working accuracy of the grinding wheel 5, but also prevents secondary splashing of debris, significantly enhancing the overall collection efficiency. This synergistic operation of mechanical cleaning and negative pressure collection builds a comprehensive debris control system from the source to the end.
[0029] The filter assembly 63 of this device achieves efficient separation and long-term operation through structural innovation. The negative pressure generated by the suction fan 64 drives dust and debris into the collection box 631. The V-shaped filter screen 634 in the collection drawer 633 inside the box plays a key role: its inclined filter screen design uses gravity to automatically guide the debris to slide to both sides, avoiding accumulation and blockage, and ensuring that the air is discharged smoothly from the filter screen 634. This not only improves the filtration efficiency but also extends the service life of the filter screen 634. In addition, the collection drawer 633 adopts a quick-release structure. When it is necessary to clean or replace the filter screen 634, the operator only needs to turn the installation screw 637 and pull out the sealing plate 635 to quickly remove the collection drawer 633, which greatly simplifies the maintenance process. This design not only achieves precise separation and collection of waste, but also reduces the difficulty of equipment maintenance through modular design, taking into account both practicality and convenience.
