4results about How to "Improve compaction quality" patented technology

This utility model relates to the field of disposable hygiene product production equipment, and particularly to an adult diaper compaction device that provides precise and uniform material conveying and mixing with good compaction effect. It includes a superabsorbent polymer (SAP) suction component, a SAP feeding component, a wood pulp fiber suction component, a feeding bin, a forming die wheel assembly, a first transfer wheel, a cotton core pressing component, a second transfer wheel, and an adsorption conveying component. The SAP feeding component is located at the output end of the SAP suction component. The feeding bin has a first inlet, a second inlet, and an outlet. The output ends of the SAP feeding component and the wood pulp fiber suction component are respectively connected to the first and second inlets of the feeding bin. The forming die wheel assembly is located at the outlet of the feeding bin. The first transfer wheel is located at the output end of the forming die wheel assembly. The cotton core pressing component and the second transfer wheel are located at the output end of the first transfer wheel.

The utility model discloses a rod valve element press structure, and relates to the technical field of rod valve element press structures, the rod valve element press structure comprises a bottom plate, a vertical shaft mounted on the bottom plate, an upper plate mounted at the end, away from the bottom plate, of the vertical shaft, a driving part mounted on the upper plate and a limiting part mounted on the bottom plate, and the limiting part is rotationally arranged on the bottom plate; the upper plate and the vertical shaft are detachably connected through a fastener, the output end of the driving part is further connected with an upper pressing head, the driving part is used for driving the upper pressing head to move in the axis direction of the driving part to achieve compaction, and the limiting part is used for positioning and assembling the valve element with the rod. The assembly and compaction device has the effects that assembly and compaction work of the valve element with the rod is efficiently completed, assembly, disassembly and adjustment of parts are facilitated, and the use flexibility and stability of equipment are improved.

A kind of ground treatment structure for the new and old filling interface area of airport pavement influence area belongs to ground structure technical field.The structure includes geogrid, over-excavation replacement layer, slope step, reinforcing step and filling layer, 2-4m over-excavation replacement layer is set on the top surface of original filling body, slope step is set on the slope of original filling body, the width of slope step is not less than 2m, one layer of reinforcing step is filled on the outside of every two slope steps, filling layer is filled outside reinforcing step again, the top of filling layer is filled to the same elevation as the top of over-excavation replacement layer, geogrid is laid on the interface of original filling body and filling layer top surface, the laying width of geogrid on filling layer and original filling body is 10-15m, and new pavement is built on the top surface of over-excavation replacement layer and filling layer.The structure improves the overall stability and reliability of new pavement foundation, reduces post-construction settlement and uneven settlement, and ensures the safety of upper pavement structure.

The invention discloses a double-drive single-steel-wheel road roller based on mechanical transmission and a control method of the double-drive single-steel-wheel road roller, and belongs to the technical field of road roller control. The road roller comprises an engine, a gearbox, a vibration system, a rear wheel mechanical driving system, a front wheel hydraulic driving system and a whole vehicle controller. The front wheel hydraulic driving system comprises a front wheel driving pump and a driving motor which are connected with the gearbox and is used for realizing front wheel auxiliary driving; the vehicle control unit controls the rotating speed of the engine and the displacement of the front wheel driving pump and the motor according to signals of the speed sensor. The control method comprises a transition mode, a common compaction mode, a high flat compaction mode and a high drive mode, distribution of driving force of front and rear wheels can be intelligently controlled according to different working conditions, energy conservation and high efficiency of mechanical transmission and flexibility and controllability of hydraulic drive are both achieved, and the working condition adaptability and operation quality of the road roller are improved.
