This invention discloses a waste recycling device for FIBC (Flexible Intermediate Bulk Container) processing, relating to the field of comprehensive environmental utilization of solid waste. The device includes a hollow frame, a hydraulic rod mounted on the hollow frame, and a pressure plate mounted on the hydraulic rod. The equipment continuously feeds FIBC waste into a flattening machine. The pressure plate is automatically triggered by the weight of the waste, achieving a complete automatic cycle of feeding, weighting, triggering, compaction, resetting, and locking, thus improving waste recycling efficiency. When not in operation, the pressure plate is rigidly limited by a limiting mechanism, preventing hydraulic system depressurization or accidental drop. This ensures uniform compaction density of the plastic waste, reducing the mixing and adhesion of plastic and impurities due to insufficient compaction, facilitating subsequent separation of plastic from other components. It also protects core components such as the hydraulic rod and pressure plate, extending equipment lifespan, reducing maintenance costs, and contributing to the resource-based recycling of plastic waste and comprehensive utilization of solid waste.

This utility model discloses a diamond composite grinding disc, comprising a mounting substrate and a diamond grinding layer. Beneficial effects: The mounting substrate and the base post are integrally connected. The shear force generated during grinding is transferred to the base post through the insertion hole, and then to the mounting substrate through the base post. The base post, instead of the adhesive, bears most of the shear force, thus significantly improving its integrity and shear resistance, avoiding peeling, and enhancing stability in use. Simultaneously, the top surface of the mounting substrate is integrally connected to top fins, which expand the heat dissipation area of ​​the top surface of the mounting substrate.
