DETAILED DESCRIPTION

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] In response to the problems that the metal chips generated by the existing dry polishing machine during the polishing process are not cleaned in time and manual cleaning is time-consuming and labor-intensive, this application designs an intelligent dry polishing machine that can automatically collect metal chips, which is described in detail below.

[0022] See also Figure 1-9 The present embodiment provides an intelligent dry polishing machine, including: a frame 10, a roller 20, a fixing fixture 24 and a cleaning mechanism; the roller 20 is rotatably connected to the frame 10, and the roller 20 is provided with a material port 21, and a material door 22 is openably and closably provided at the material port 21, and the material port 21 leads inward to a polishing cavity 25 provided inside the roller 20; the fixing fixture 24 is provided in the polishing cavity 25, and the fixing fixture 24 is fixedly connected to the roller 20 for positioning the workpiece; the cleaning mechanism is used to collect metal powder chips in the polishing cavity 25.

[0023] It will be appreciated that during the polishing process, the material gate 22 of the polishing machine of this embodiment is closed, and the cleaning mechanism within the drum 20 begins to absorb and collect the metal chips generated during the polishing process. The workpiece is secured within the drum 20 by a fixture 24, and the drum 20 rotates according to set parameters (such as speed, time, and direction of rotation) to ensure full contact between the workpiece and the abrasive, completing the polishing operation. After the polishing is completed, the material gate 22 opens, and the cleaning mechanism collects the collected metal chips for centralized processing. The operator can then conveniently clean the collected chips and prepare for the next round of polishing. This embodiment implements an automatic cleaning function during the polishing process, reducing manual intervention and labor intensity. Furthermore, this embodiment can promptly collect metal chips during the polishing process, preventing damage to the workpiece surface quality and equipment caused by chip accumulation, thereby improving cleaning efficiency.

[0024] In some embodiments, the cleaning mechanism includes: a first magnetic member 30, which is arranged on a side facing the light-sliding cavity 25 when the material door 22 is in a closed state.

[0025] In this embodiment, when the material door 22 is closed, the first magnetic component 30 is arranged on the side of the material door 22 facing the polishing chamber 25. The magnetic field generated by the first magnetic component 30 can absorb metal chips generated during the polishing process and can effectively collect metal chips.

[0026] In some embodiments, a receiving groove 23 is provided in the wall of the drum 20, and the receiving groove 23 is connected to the material port 21; a slide rail is provided extending from the material port 21 to the interior of the receiving groove 23, and the two sides of the material door 22 are respectively slidably connected to the two slide rails; the material door 22 can slide along the slide rail toward the material port 21 or the receiving groove 23, so that the material door 22 slides to a closed state or an open state; the cleaning mechanism includes a collection component, and the collection component includes a collection box 31 and a scraper 32. The collection box 31 is arranged to face the light cavity 25 when the material door 22 is in the open state. On one side, the opening of the collecting box 31 faces the material door 22 when it is in the open state, and the projection of the material door 22 toward the collecting box 31 when it is in the open state completely falls within the range of the opening of the collecting box 31; the scraper plate 32 is arranged at the opening of the collecting box 31, and the scraping side of the scraper plate 32 extends toward the sliding path of the material door 22; in the process of the material door 22 sliding to the open state, the first magnetic member 30 slides with the material door 22 and contacts the scraping side of the scraper plate 32, so that the metal powder adsorbed by the first magnetic member 30 is scraped into the collecting box 31.

[0027] It is understood that the material door 22 slides within the wall of the drum 20 via a slide rail to open and close the material port 21. The slide rail serves as a guide for the material door 22, ensuring that the material door 22 can move smoothly along a predetermined path. As the material door 22 moves open, it drives the first magnetic element 30 to move, causing it to come into contact with the scraping side of the scraper plate 32, thereby scraping the absorbed metal powder into the collection box 31.

[0028] Specifically, during the polishing process, the material door 22 is in a closed state, and the cleaning mechanism begins to absorb and collect metal chips in the polishing chamber 25. The workpiece is fixed inside the drum 20 by the fixing fixture 24, and the drum 20 rotates according to the set parameters to make the workpiece fully contact with the abrasive to complete the polishing operation. After the polishing is completed, the material door 22 is opened by sliding along the slide rail. In the process of the material door 22 sliding open, the material door 22 drives the first magnetic suction part 30 in the cleaning mechanism to move, and it conflicts with the scraper plate 32, and the metal chips are scraped into the collection box 31. This embodiment can collect the metal chips generated in the polishing process in a timely and thorough manner through the cooperation of the material door 22 translation and the scraper plate 32, avoid the damage to the surface quality of the workpiece and the equipment caused by the accumulation of chips, and significantly improve the cleaning efficiency.

[0029] In some embodiments, two elongated slots are provided on either side of the receiving tank 23. The collection assembly further includes a connecting rod 33 and an elastic member 34. The ends of the connecting rod 33 are slidably connected to the two elongated slots. The elastic member 34 is used to provide elastic force for the connecting rod 33 to move away from the collection box 31 and toward the sliding path of the material door 22. A scraper plate 32 is connected to the connecting rod 33. The elastic force of the elastic member 34 ensures that the scraper plate 32 always maintains close contact with the sliding path of the material door 22. Even if the material door 22 is subjected to certain impacts or vibrations during its sliding process, the scraper plate 32 can remain stable and effectively scrape off metal chips. The elastic force of the elastic member 34 allows the scraper plate 32 to more closely adhere to the sliding path of the material door 22, effectively scraping off metal chips and improving the thoroughness and efficiency of cleaning.

[0030] Furthermore, the scraping side includes a first wedge-shaped slope close to the material port 21, a second wedge-shaped slope away from the material port 21, and a top edge formed by the intersection of the first wedge-shaped slope and the second wedge-shaped slope; the first magnetic component 30 is provided with a third wedge-shaped slope on the side facing the open position of the material door 22, and the first magnetic component 30 is provided with a fourth wedge-shaped slope on the side facing the closed position of the material door 22; the first wedge-shaped slope corresponds to the third wedge-shaped slope and has the same slope, and the second wedge-shaped slope corresponds to the fourth wedge-shaped slope and has the same slope.

[0031] In some embodiments, the slide rail is provided with a power connection bar, which is electrically connected to a power source; the first magnetic component 30 is an electromagnet, and the first magnetic component 30 is provided with a power connection protrusion facing the slide rail, which is electrically connected to the electromagnet; wherein the power connection bar is provided in a relative area of ​​the slide rail corresponding to the closed state of the material door 22; when the material door 22 is in a closed state, the power connection protrusion contacts and is electrically connected to the power connection bar, so that the first magnetic component 30 is energized and generates a magnetic attraction force; when the material door 22 is in an open state, the power connection protrusion is separated from the power connection bar, so that the first magnetic component 30 is de-energized and the magnetic attraction force disappears.

[0032] Specifically, when the material door 22 moves along the slide rail to a closed position, the power-connection protrusion contacts the power bar, energizing the first electromagnet and beginning to attract the metal chips within the polishing chamber 25. After polishing is complete, the material door 22 slides open along the slide rail, the power-connection protrusion separates from the power bar, and the first electromagnet is de-energized, allowing the attracted metal chips to naturally fall under the action of gravity into the collection box 31. In this embodiment, the electromagnet's on and off are synchronized with the opening and closing of the material door 22, eliminating the need for additional control operations and further enhancing the automation level of the equipment. The first electromagnet is energized only when the material door 22 is closed, avoiding unnecessary energy consumption and improving energy efficiency.

[0033] Furthermore, a plurality of first magnetic members 30 are provided, and the plurality of first magnetic members 30 are spliced ​​along the direction of travel of the material door 22. The plurality of first magnetic members 30 are spliced ​​along the direction of travel of the material door 22 to form a continuous adsorption area, and each first magnetic member 30 is in contact with the power bar on the slide rail through the power connection protrusion to realize power on and power off control. In some embodiments, the collection box 31 is removably connected to the drum 20 in a drawer-type manner. The drawer-type collection box 31 allows operators to quickly and conveniently clean metal chips without complicated disassembly, reducing maintenance time and labor intensity. The sealed design of the collection box 31 effectively prevents metal chips from leaking, maintaining a clean working environment and reducing the impact on the operator's health.

[0034] In some embodiments, an electric conductor is provided at the end point where the material door 22 moves toward the accommodating groove 23, and the electric conductor is electrically connected to the power supply; the collection box 31 is provided with a power connection groove corresponding to the electric conductor, and the bottom of the collection box 31 is provided with a second magnetic component 311, the second magnetic component 311 is an electromagnet, and the second magnetic component 311 is electrically connected to the power connection groove; when the material door 22 moves into the accommodating groove 23 to an open state, the electric conductor is embedded in the power connection groove, so that the power supply is electrically connected to the second magnetic component 311 through the electric conductor and the power connection groove.

[0035] In this embodiment, an electric conductor is provided at the end point where the material door 22 moves toward the receiving groove 23, and the electric conductor is electrically connected to the power supply. The collection box 31 is provided with a power connection groove corresponding to the electric conductor, and the bottom of the collection box 31 is provided with a second magnetic component 311, which is an electromagnet and is electrically connected to the power connection groove. When the material door 22 moves into the receiving groove 23 to an open state, the electric conductor is embedded in the power connection groove, and the power supply is electrically connected to the second magnetic component 311 through the electric conductor and the power connection groove, so that the second magnetic component 311 is energized and generates a magnetic force to absorb the fallen metal chips. The second magnetic component 311 is energized when the material door 22 is opened, and further absorbs the fallen metal chips to prevent the chips from flying again, thereby improving the collection efficiency and cleaning effect.

[0036] This embodiment also provides a polishing process, including the following steps: S1: Operate the material door to open the material inlet, position the workpiece on the fixed fixture 24, and introduce the abrasive into the drum; S2: Operate the material door to close the material port, the pneumatic polishing machine rotates the drum, and the cleaning mechanism works to absorb the metal powder generated inside the drum during rotation; S3: Operate the material door to open the material opening, take the workpiece out of the fixing fixture 24, and take out the residual abrasive in the drum; S4: Operate the cleaning mechanism to dump the collected metal powder.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention.
