[0039] In other words, as Figures 1 to 4 shown, the waste collecting pipeline according to the embodiment of the utility model mainly includes negative pressure collecting pipe 10 and crushing assembly 20, the negative pressure collecting pipe 10 is hard tube, the negative pressure collecting pipe 10 is equipped with at least two openings, one opening can be inlet, and the other opening can be outlet, and the waste 200, such as strip waste 200, can enter the waste collecting pipeline from inlet and can be discharged from outlet. Crushing assembly 20 is installed in negative pressure collecting pipe 10, and crushing assembly 20 is located between inlet and outlet, so that crushing assembly 20 is located on the path of waste 200, so that the waste 200 can be crushed by crushing assembly 20, and the waste 200 with large volume such as strip can be crushed into waste 200 with small volume, and then the waste 200 can be avoided to be blocked by winding into a group.

[0040] Therefore, according to the waste collecting pipeline provided by the embodiment, the waste 200 with large volume such as strip can be effectively crushed into waste 200 with small volume by the crushing assembly 20 arranged in negative pressure collecting pipe 10, so that the waste 200 can flow smoothly in negative pressure collecting pipe 10, effectively avoiding the waste 200 to be blocked by winding in the pipeline, thereby effectively improving the efficiency of waste 200 collection, so that the waste 200 can quickly and stably enter from inlet and be discharged from outlet, reducing the downtime of pole piece production equipment 100 caused by pipeline blockage, and effectively improving the efficiency and continuity of pole piece production.

[0041] In some specific embodiments of the utility model, negative pressure collecting pipe 10 is equipped with at least one bending part 11, and the first bending part 11 is equipped with crushing assembly 20 on the side close to inlet in the direction from inlet to outlet.

[0042] That is, negative pressure collecting pipe 10 can be straight pipe, and can also be pipeline with one or more bending parts 11.
