Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 7, the utility model discloses a this kind of a multistage breaker for drawing metallic copper from old and useless circuit board, including one-level crushing mechanism 10 and second grade crushing mechanism 11, one-level crushing mechanism 10 is connected with second grade crushing mechanism 11 through connecting pipe 12.
The primary crushing mechanism 10 includes a hopper 13, a first motor 14, a second motor 15, a first air cylinder 16, a first cutting roller 17, and a second cutting roller 18. The first cutting roller 17 and the second cutting roller 18 are both mounted in the hopper 13, and the first motor 14 and the second motor 15 are mounted outside the hopper 13. The first motor 14 is connected with the first cutting roller 17, the second motor 15 is connected with the second cutting roller 18, a bearing seat 19 is arranged at the other end of the second cutting roller 18, the first air cylinder 16 is installed on the outer wall of the hopper 13, and the first air cylinder 16 is connected to both the second motor 15 and the bearing seat 19. While an annular groove 131 is provided on the hopper 13, and the second cutting roller 18 is mounted in the annular groove 131. The second cutting roller 18 is movable in the annular groove 131.
The first cutting roller 17 is circular in cross section and the second cutting roller 18 is elliptical in cross section.
When crushing is required, the first motor 14 and the second motor 15 rotate, the first cutting roller 17 does not move, and the second cutting roller 18 can move under the push of the first air cylinder 16. Since the cross section of the second cutting roller 18 is elliptical, when the longer end is close to the first cutting roller 17, the first air cylinder 16 pushes the second cutting roller 18 away from the first cutting roller 17. And when approaching, the first cylinder 16 pulls the second cutting roller 18 back. Therefore, the crushing is convenient, and the blanking blockage can be prevented.
The upper ends of the first cutting roller 17 and the second cutting roller 18 are provided with a material guide plate 191, the material guide plate 191 is arranged on the inner wall of the hopper 13, and the material guide plate 191 can conveniently guide circuit boards to be crushed into the hopper 13.
