Description

Technical Field

[0001] The utility model relates to the technical field of jewelry processing, and more specifically, to a precious metal jewelry polishing dust recovery machine. Background Art

[0002] During the processing of jewelry, it is usually necessary to polish the surface of the jewelry to make it shiny and mirror-like, thereby improving the beauty of the jewelry. For the polishing of jewelry, a cloth wheel polishing machine is generally used for processing. A lot of dust will be generated during the polishing process, which is not only easy to cause environmental pollution, but also for precious metals, the dust contains precious metal powder, which is directly discarded as garbage, which is easy to cause a waste of resources. Therefore, how to recycle the polishing dust of precious metal jewelry has become a problem.

[0003] In the prior art, the publication number is CN 217702870 U, which discloses a dust collection device for a cloth wheel polishing machine, which relates to the technical field of acrylic material processing equipment, and includes a mounting assembly, a dust collector body is fixed to the bottom wall of the inner cavity of the mounting assembly, a dust collection hose that penetrates the mounting assembly is fixed to the input end of the dust collector body, and a dust collection hood is fixedly connected to the end of the dust collection hose away from the dust collector body, and a transverse cylinder is fixed to the upper and lower ends of the side wall of the mounting assembly close to the dust collection hood, and a second push plate is fixed to the end of the horizontal output shaft of the two groups of transverse cylinders, and the outer wall of the second push plate is fixed to the outer wall of the dust collection hood. The present application drives the dust collection hood to move left and right to an appropriate position by starting the transverse cylinder to extend and retract, so that the dust collection hood is located directly behind the cloth wheel polishing machine, and then starts the dust collector body to automatically remove dust, and at the same time, the position of the dust collection hood can be fixed to avoid the situation where the dust collection efficiency is reduced due to the displacement of the dust collection hood caused by the vibration of the dust collector body during operation.

[0004] Although the existing dust collection device of the cloth wheel polishing machine can collect the jewelry polishing dust, the airflow adsorbed by the dust collection hood is the air around the cloth wheel, and the cloth wheel is exposed to the outside. The collected polishing dust may contain other impurities, such as hair of the staff, paper scraps in the workshop, etc. The mixing of impurities is not conducive to the subsequent separation and recycling of the polishing dust.

[0005] Therefore, a precious metal jewelry polishing dust recovery machine needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a precious metal jewelry polishing dust recovery machine in view of the above-mentioned deficiencies in the prior art, which can prevent other impurities from mixing into the polishing dust, thereby facilitating the subsequent separation and recovery of the polishing dust.

An inclined air collecting pipe 7 is provided on the workbench 2 below the cloth wheel 3. The air inlet of the air collecting pipe 7 can be a bell-shaped mouth. The air inlet of the air collecting pipe 7 faces directly below the cloth wheel 3, and a sieve plate 8 is threadedly connected to the air inlet of the air collecting pipe 7 for easy disassembly and assembly. A plurality of sieve holes 9 are provided on the top surface of the sieve plate 8, and the air outlet of the air collecting pipe 7 is connected to the dust collection component.

[0025] The jewelry polishing dust recovery machine of the utility model is provided with a transparent isolation cover 1 on the periphery of a cloth wheel 3, and a cloth cover 5 is provided on an operating channel 4. When polishing, a worker extends the handheld jewelry from the operating channel 4 into the isolation cover 1 for polishing. Since the elastic ring 6 is clamped on the arm of the worker, the gap between the arm and the operating channel 4 is replaced by the cloth cover 5. During the polishing process, the dust suction component extracts the dust generated by the polishing, and the external airflow needs to pass through the cloth cover 5 before entering the isolation cover 1, so that other impurities can be prevented from mixing into the polishing dust, thereby facilitating the subsequent separation and recycling of the polishing dust.

[0026] At the same time, the jewelry polishing dust recovery machine, by setting the air collecting pipe 7 to an inclined structure, and the air inlet is facing directly below the cloth wheel 3, the dust generated by jewelry polishing can be directly splashed into the air collecting pipe 7, which is more conducive to the suction of dust, while reducing the pollution to the inner wall of the workbench 2 and the isolation cover 1, and the detachable screen plate 7 is provided, which can reduce the mixing of cloth scraps dropped by the cloth wheel due to wear and tear into the dust, and is also convenient for disassembly and maintenance
