Description

Technical Field

[0001] The invention relates to the technical field of spectacle frame processing, in particular to a precision polishing processing device for spectacle frames. Background Art

[0002] In the production and processing of eyeglass frames, polishing is one of the key processes, the purpose of which is to make the surface of the eyeglass frames smooth and flawless, and to improve the appearance quality and wearing comfort of the product. At present, a drum polisher is one of the commonly used polishing equipment. Its working principle is to put the eyeglass frames and polishing sand into a drum together, and the eyeglass frames and polishing sand are rubbed against each other through the rotation of the drum, so as to achieve the polishing effect. However, the existing drum polisher still has the following shortcomings in practical applications, which makes it difficult to meet the requirements of the modern eyewear manufacturing industry for high efficiency, high quality, low energy consumption and convenient operation; After the existing drum polisher finishes polishing, a small amount of polishing sand often remains on the surface of the eyeglass frame. If these residues are not thoroughly cleaned, the subsequent processing and final quality of the eyeglass frame will be affected. The current cleaning methods are mostly manual cleaning or simple mechanical blowing, which has low cleaning efficiency and is not thorough. It is easy to miss the polishing sand in small parts, increasing the defective rate. In the polishing process of eyeglass frames, it is usually necessary to perform rough polishing first and then fine polishing to achieve the ideal surface finish; however, the existing drum polishing machines mostly require manual operation when switching between coarse and fine polishing sands, which is not only time-consuming and labor-intensive, but also prone to polishing sand contamination or mixing due to improper operation, affecting the polishing effect; in addition, frequent manual intervention also reduces the automation degree and production efficiency of the equipment; Polishing sand will gradually wear out during use. When it is worn to a certain extent, its polishing effect will be significantly reduced. Existing drum polishing machines usually need to replace the polishing sand regularly, which not only increases production costs, but also wastes a large amount of sand that still has a certain polishing ability. To this end, the present invention proposes a novel eyeglass frame precision polishing processing equipment which can efficiently clean, automatically switch polishing sand, save costs, reduce energy consumption and is easy to operate.

[0013] The present invention provides a precision polishing equipment for eyeglass frames, which has the following beneficial effects: (1) A precision polishing processing equipment for eyeglass frames. When using the device, first unfasten the connection buckle between the door and the drum, and snap the eyeglass frame into the slot on the surface of the fixed plate, and then close the door; the second driving mechanism is started, and the first motor drives the second gear ring to rotate through the first transmission gear, thereby driving the drum and the polishing sand inside it to roll, so that the polishing sand contacts the eyeglass frame to achieve surface polishing; after polishing is completed, the drum stops rotating, the air pump is started, and the impeller is driven to rotate by the high-speed airflow, thereby driving the large gear, the small gear and the rotating shaft to rotate, so that the fixed plate and the eyeglass frame flip over, causing the residual polishing sand to fall off; at the same time, the rotation of the rotating shaft drives the rubber rod to periodically contact and separate from the wind rod, and the reaction force generated by the rubber rod when restoring its deformation causes the rotating shaft to vibrate, further cleaning the polishing sand on the surface of the eyeglass frame; in addition, the air in the wind slot enters the wind rod through the exhaust pipe, and is blown to the surface of the eyeglass frame through the air outlet, achieving the third cleaning; the entire process makes full use of the wind power of the air pump for recycling, efficiently cleans the residual polishing sand on the surface of the eyeglass frame, and reduces energy consumption; (2) A precision polishing equipment for eyeglass frames, after the polishing process is completed, the coarse polishing sand in the drum naturally settles to the bottom of the drum due to gravity; at this time, the second motor is started to drive the second transmission gear to rotate, thereby driving the switching drum inside the drum to rotate synchronously; the opening of the switching drum is precisely aligned with the coarse polishing sand storage bin below during the rotation process, so that the inside of the drum is connected to the storage bin; under the action of gravity, the coarse polishing sand smoothly falls from the drum into the storage bin for storage; then, the second motor continues to drive the switching drum to rotate, so that the opening and the connecting channel of the coarse polishing sand storage bin are misaligned, thereby closing the storage bin and ensuring the safe storage of the coarse polishing sand; the switching drum continues to rotate, and its opening is precisely aligned with the fine polishing sand storage bin above, and the fine polishing sand then falls from the storage bin into the drum, completing the automatic switching from coarse polishing sand to fine polishing sand; this process realizes that the equipment automatically switches to the fine polishing process without manual intervention after the coarse polishing process is completed, which not only improves the polishing accuracy, but also significantly reduces manual operation, greatly improves the automation level and operation convenience of the equipment, and provides an efficient and reliable solution for the precision polishing of eyeglass frames; (3) In the precision polishing processing equipment for eyeglass frames, when fine polishing sand is being polished inside the drum, the slide plate at the bottom of the coarse polishing sand storage bin is operated to slide and pull it out, thereby opening the passage between the coarse polishing sand storage bin and the waste sand tank; at this time, the coarse polishing sand in the storage bin rolls inside the storage bin driven by the rotation of the drum; during the rolling process, the coarse polishing sand is screened by the sieve plate, and the sand particles with severe wear and small particles can pass through the sieve plate and fall into the waste sand tank below; when the opening of the waste sand tank faces downward, the waste sand is automatically discharged, thereby realizing the automatic elimination of the polishing sand with severe wear and avoiding the polishing effect caused by excessive wear of the polishing sand. In addition, during the rotation of the drum, the connecting rod rotates synchronously with the drum; since one end of the connecting rod is connected to the screen plate, the other end is always in contact with the edge of the guide plate under the tension of the spring; the undulating structure of the edge of the guide plate enables the connecting rod to reciprocate horizontally during the rotation, thereby driving the screen plate to move back and forth accordingly; this design further enhances the screening effect of the screen plate, improves the screening efficiency of waste sand, and ensures that the coarse polishing sand in the storage bin always maintains good polishing performance, thereby extending the service life of the polishing sand and improving the overall operation efficiency and polishing quality of the equipment.

[0014] This solves the problems of poor cleaning effect after polishing, complicated polishing sand switching operation, large polishing sand loss and high maintenance cost of existing polishing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

While the connecting rod 509 rotates, under the pulling force of the spring 506, one end of the connecting rod 509 can always keep in contact with the edge of the guide plate 510, and the undulating structure of the edge of the guide plate 510 enables the connecting rod 509 to reciprocate in the horizontal direction, so that the connecting rod 509 can drive the sieve plate 507 to move back and forth, which is beneficial to further improve the effect of screening out waste sand.
