Abstract

The invention discloses a crushing device for a wasted circuit board, and relates to the field of circuit board recycling devices. The crushing device for the wasted circuit board comprises a support,a discharging port which is formed in the support and is used for discharging the broken circuit board, a screening plate which is positioned at the upper part of the discharging port, a second crusher which is arranged at the upper part of the support, a first crusher which is mounted on the upper surface of the second crusher, and a feeding device which is arranged at an opening in one side ofthe first crusher and is used for conveying the wasted circuit board. According to the crushing device for the wasted circuit board, the circuit board is pre-crushed through the first crusher and is crushed for the second time through the second crusher, and thus the problem of serious splashing is caused by the wasted circuit board in rapid contact with a high-speed rotating crushing cutter during direct crushing in the prior art can be solved.

Description

technical field [0001] The present application relates to the field of circuit board recycling devices, in particular to a crushing device for waste circuit boards. Background technique [0002] Existing waste circuit boards are usually in the form of plates. During recycling and crushing, there will be serious splashing problems when they are directly in contact with the high-speed rotating crushing knife. Secondly, the crushed waste circuit boards are not crushed when they pass through the screen plate. Larger waste circuit boards will continue to remain on the screen plate causing clogging of waste circuit boards. [0003] For example, the Chinese utility model with the notification number CN 202909793U discloses a circuit board crusher, which includes a frame, a power mechanism, a transmission device and a crushing mechanism. The feed inlet is arranged on one side of the top of the box and communicated with it, the screen is arranged at the bottom of the box, and the ou...
