Description

Pulp package steel wire shearing device

Technical Field

The utility model belongs to the technical field of fiber production, and particularly relates to a pulp ladle steel wire shearing device.

Background

In the fiber production process, pulp is an intermediate product that requires further processing to form fibers. After the pulp is produced, the pulp needs to be transferred to the next production and addition equipment for processing due to different production and manufacturing environments. The pulp is transferred by forming small bags by first forming large bags, stacking the small bags to form large bags, bundling the large bags by steel wires, and fixing the stacked large bags to avoid the large bags from being decomposed. The usual way of stacking is to stack the packets in two columns, each column overlapping 4 packets, i.e. a total of 8 packets are combined into one large packet.

However, the pulp bale also needs to be split before it is transferred to the next production process. The existing splitting mode is to cut the steel wire by adopting a manual hand-held cutting pliers. The steel wires can be tightened when the pulp bale is bound, so that the pulp bale is ensured not to be decomposed. Therefore, when a worker shears the steel wire, the originally tightened steel wire can be sprung out during shearing, so that the damage to the worker is easy to cause, and the danger degree is high.
