This application relates to a polyacrylamide spiral granulator, belonging to the field of granulators. It includes a feed cylinder, a motor, a spiral conveyor, a die plate, and a conveying cylinder. The conveying cylinder is horizontally positioned, and the feed cylinder is vertically positioned above it, with its lower end connected to the conveying cylinder. The spiral conveyor is disposed inside the conveying cylinder, and the motor is located on one side of the conveying cylinder and drives the spiral conveyor. The die plate includes a fixed plate and a rotating plate. The fixed plate has multiple discharge holes (first type), and the rotating plate has multiple discharge holes (second type). The rotating plate and the fixed plate rotate relative to each other. The conveying cylinder is equipped with a fixing component to fix the positions of both the rotating plate and the fixed plate. This application has the effect of allowing users to quickly adjust the particle size of the extruded polyacrylamide granules.

The application relates to the technical field of metal material surface strengthening, in particular to a self-adaptive laser shock peening method and system based on light path dynamic regulation and real-time monitoring. The method comprises the following steps: preprocessing and constructing a digital twin model, dividing different curvature processing areas and presetting peening parameters; dynamic focusing galvanometer and beam shaper are cooperated to ensure that laser is vertically incident and the spot shape and area are constant; an adjustable nozzle adaptively supplies a constraint layer, an ultrasonic sensor real-timely monitors water film thickness and feeds back adjustment; a high-speed spectrometer and an acoustic sensor collect multiple signals, plasma parameters are inversely deduced to evaluate the shock effect, energy compensation is triggered when an abnormality occurs, and closed-loop control is formed. The system corresponds to three-dimensional scanning, digital twin processing, dynamic beam adjustment, constraint layer supply, quality monitoring module and a control system. The method and system are suitable for complex curved surface workpieces, improve peening uniformity and stability, and are suitable for high-precision peening processing of materials such as titanium alloy.

This invention proposes a single-shear apparatus and shearing method for uniform shear strain distribution. The shearing method includes installing a shearing assembly, loading the sample into the stack of plates of the shearing assembly, installing a vertical loading device and a shear force loading device, applying a vertical load to the sample to consolidate the sample, installing a left-side sliding limit device, and applying a horizontal load to the consolidated sample for shearing. This invention can precisely control the shearing direction, solve the problem of shear force direction deflection in the prior art, and enable uniform shearing of the sample, ensuring uniform vertical shear strain distribution.
