Description

Technical Field

[0001] The utility model relates to the technical field of circuit board recycling, in particular to a waste circuit board resource recycling device. Background Art

[0002] The names of circuit boards include: circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be called printed circuit boards or printed circuit boards, and the English name is (Printed Circuit Board) PCB. Since all parts of the circuit board have utilization value, the recycling and reuse of waste circuit boards is particularly important.

[0003] In the waste circuit board recycling system, the circuit boards need to be crushed first, but when the existing crushing rollers are in use, the gap between the two is fixed, so the volume of the material at the crushing point is fixed. When different crushing requirements are required, the fixed gap limits the flexibility of the crushing process. Circuit boards of different types or sizes may require different degrees of crushing, but since the gap is fixed, it cannot be adjusted according to specific needs, resulting in the inability to meet different crushing requirements. Therefore, it is necessary to redesign a waste circuit board resource recycling device to address the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3, a waste circuit board resource recycling device comprises a recycling box 1, the upper end of the recycling box 1 is open, and two groups of crushing rollers 11 are rotatably connected in the recycling box 1, and the outer walls of the two groups of crushing rollers 11 are conical. The inner wall of the recycling box 1 is rotatably connected with a threaded rod 2, and the threaded rod 2 is connected with a drop hopper 5 through a connecting mechanism. The drop hopper 5 is located just above the center point of the two groups of crushing rollers 11. A drop trough 12 is opened on the side wall of the recycling box 1, and the drop trough 12 is communicated with the inside of the recycling box 1. A drop plate 10 is fixedly connected to the inner wall of the recycling box 1, and the drop plate 10 extends to the outside of the recycling box 1. The connecting mechanism comprises a slider 4 threadedly connected to the threaded section of the threaded rod 2, and the slider 4 is connected to the drop hopper 5 through a connecting rod. The outer walls of the two groups of crushing rollers 11 are conical, so the old circuit boards can be put into different positions to crush the circuit boards to different degrees, and the drop hopper 5 can be guided. When putting in, it can be put in from the drop hopper 5, and the threaded rod 2 can accurately control the position of the drop hopper 5.

[0021] Reference Figure 1 and Figure 2 The inner wall of the recycling box 1 is fixedly connected with a limit rod 3, and the outer wall of the limit rod 3 is engraved with scale lines. The limit rod 3 is slidably connected with the slider 4. The scale lines set on the limit rod 3 can make the drop hopper 5 slide accurately to the specified position when driving it to move, so as to ensure the degree of crushing the circuit board.

[0022] Reference Figure 1 The outer wall of the recycling box 1 is rotated with two sets of gears 7, which are meshed with each other. The two sets of gears 7 are fixedly connected to the adjacent crushing rollers 11 respectively. The two sets of gears 7 are meshed with each other, and then the drop hopper 5 can be driven to slide through a single set of servo motors 9.

[0023] Reference Figure 2 and Figure 3 The outer wall of the recycling box 1 is fixedly connected with a fixed plate 8, the outer wall of the fixed plate 8 is L-shaped, the outer wall of the fixed plate 8 is fixedly connected with a servo motor 9, the output shaft of the servo motor 9 is fixedly connected with a gear 7, the outer wall of the recycling box 1 is rotatably connected with a turning handle 6, the turning handle 6 is coaxially fixedly connected with the threaded rod 2, and the outer wall of the turning handle 6 is provided with an anti-slip pad to increase the friction when the turning handle 6 is rotated.

[0024] In the utility model, when the device is used, the handle 6 is turned to drive the threaded rod 2 to rotate, and then the slider 4 on its threaded section drives the drop hopper 5 to slide horizontally, and the scale line on the limit rod 3 is observed. When it slides to the specified position, the servo motor 9 is started, and the output shaft of the servo motor 9 drives the adjacent gear 7 to rotate. With the help of the meshing of the two sets of gears 7, the two sets of crushing rollers 11 are synchronously driven to rotate. At this time, the circuit board to be crushed is put into the drop hopper 5. Since the crushing roller 11 is conical, when the drop hopper 5 is at different positions, the spacing between the two sets of crushing rollers 11 is not consistent, thereby meeting different degrees of crushing requirements, and the crushed circuit board slides out to the outside through the blanking plate 10.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
