Description

Technical Field

[0001] This utility model belongs to the technical field of steel coil baling machine equipment, and specifically relates to a biting gripping mechanism for a steel coil baling machine. Background Technology

[0002] Steel coil baling machines belong to the field of metal processing post-processing technology within industrial automation equipment. Specifically applied in the steel industry, they are primarily used in the final stage of the steel production process to automatically bundle (usually using steel strapping or PET strapping) finished hot-rolled or cold-rolled steel coils. This ensures they maintain a tight and stable shape during transportation, hoisting, and storage, preventing loosening and deformation, guaranteeing product quality, and facilitating subsequent logistics operations. Their core functions include automatic strapping, winding, locking, and cutting. They are one of the key pieces of equipment for modern steel enterprises to improve packaging efficiency, ensure product safety, and reduce labor costs.

[0003] In stainless steel strip hot annealing and pickling production lines, steel coil bundling machines are key equipment in the later stages of steel production. Their main function is to efficiently and stably package rolled steel coils using automated bundling processes to meet the needs of transportation, storage, and subsequent processing. The snap-lock unit is the core component of the steel coil bundling machine. Its principle involves a piston rod pushing the snap-lock unit into a pre-snap state, i.e., single-end clamping. When the cylinder is pressurized, the snap-lock unit is pushed into the snap-lock state to complete the buckling and cutting of the strapping.

[0004] The design patent with patent number 2021305691134 discloses a gripper claw (the outer gripper claw of the baler's gripper module). In the aforementioned prior art, due to prolonged use and excessive wear, damage to the gripper claw within the gripper unit can lead to the following problems: 1. Inability to bundle: Damaged grippers prevent the gripper unit from completing the binding, requiring manual bundling and increasing labor costs; 2. Risk of loose strapping: Insecure gripping cannot ensure the steel coil's stability during storage, transportation, or hoisting, leading to loose strapping and affecting production efficiency; 3. Decreased product quality: Deviation can cause uneven cooling of the strip steel, affecting its mechanical properties and surface quality. Therefore, the gripper claw needs to be replaced after a period of use.

[0005] However, the aforementioned existing technologies are integrated designs, requiring the entire system to be replaced during replacement, which is costly and needs further improvement. Utility Model Content
