Description
Technical Field
[0001] This utility model relates to the field of circuit board recycling technology, specifically a crushing device for circuit board recycling. Background Technology
[0002] Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, PCBs, aluminum-based boards, high-frequency boards, thick copper boards, impedance boards, ultra-thin circuit boards, and printed circuit boards (copper etching technology). Circuit boards miniaturize and visualize circuits, playing a crucial role in the mass production of fixed circuits and optimizing the layout of electrical appliances. They are characterized by high wiring density, light weight, thinness, and good flexibility. The emergence and development of FPC and PCB have spurred the development of this new product, rigid-flex PCB. Existing patent CN218902129U discloses a multi-stage crushing device for recycling waste circuit boards. This invention addresses the technical problem that most existing circuit board recycling crushing devices repeatedly crush circuit boards once or multiple times, resulting in excessively long crushing times and insufficient crushing of the circuit boards, thus reducing the crushing effect. The device includes a crushing chamber with a support leg at one corner and a discharge port at the bottom center. A rotating motor drives a rotating shaft, and crushing blades initially cut and crush the waste circuit boards, forming particles of different sizes that fall and come into contact with a rotating guide plate, throwing them onto an impact plate. Upon impact, the particles collide with a crushing cone, breaking them apart. The crushed particles then fall into a grinding tank where they are squeezed and ground by the teeth of two grinding gears, ensuring thorough crushing and improving the crushing effect.
[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In practical applications, due to the different sizes of circuit boards, the size of the crushing mechanism needs to be adjusted during subsequent use. If it is inconvenient to adjust the mechanism, the ease of use of the device will be affected. Therefore, we propose a crushing device for circuit board recycling to solve the above-mentioned problems. Utility Model Content
