Product Overview

The KR‑410 paper‑tube compression‑strength tester is a dedicated electromechanical lab instrument for evaluating radial flat‑crush performance of paper cores, yarn‑winding tubes, composite paper cans and similar tubular containers. Under constant‑speed vertical compression, it captures peak crush‑load and deformation data when specimens collapse, delivering objective strength indicators to assess tubular‑product anti‑pressure capacity for stacking, transit and storage scenarios.

This bench‑top system adheres to BB/T 0032, ISO 11093‑9, GB/T 22906.9 and GB/T 27591‑2011 specifications. It serves paper‑tube production workshops, textile‑yarn factories, packaging‑manufacturing plants, material‑R&D departments and accredited third‑party QC laboratories for incoming‑material acceptance, finished‑goods grading and product‑formula optimisation.

Core Product Competitive Advantages

1. High‑Precision Load‑Cell Sensing System Premium force‑sensor hardware delivers 1/20000 high‑resolution data acquisition with measurement accuracy controlled within ±0.5 %. Multiple‑range capacity options (200 kg / 500 kg / 1000 kg) are selectable to fit light‑duty thin‑wall tubes as well as heavy‑wall industrial‑grade paper‑core samples.
2. Adjustable Stepper‑Motor Driven Compression Speed Continuously configurable test‑speed from 10 mm/min up to 200 mm/min. Operators set compression velocity in accordance with different standard‑test requirements. Stable stepper‑motor drive guarantees uniform downward movement of pressing platen and minimises mechanical disturbance to force‑readings.
3. Multi‑Unit Switchable Intelligent Control & On‑Site Print‑Out Large‑screen digital display presents real‑time load‑value and test‑progress. Supports quick unit‑conversion between N, kgf and lbf. Built‑in miniature thermal printer outputs hard‑copy test‑reports right after each run, eliminating extra PC‑printing operations for fast‑paced production‑lab workflows.
4. Rigid Large‑Area Parallel Press‑Platen Assembly 300 × 300 mm heavy‑duty parallel pressing platens maintain good parallelism during compression cycles. The platen gap can be custom‑configured beyond the standard 300 mm dimension, adapting to diverse paper‑tube length specifications. Robust welded frame resists deflection under high‑load compression‑tests.
5. User‑Friendly All‑In‑One Cabinet Layout Integrated cabinet‑style mechanical‑structure consolidates drive‑unit, sensor and control panel. All operating buttons are centrally arranged on the front‑side panel for straightforward setup. After‑test auto‑return function reduces repetitive manual‑handling workload for batch‑specimen testing.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place tester on rigid, vibration‑isolated level floor. Power‑on equipment and finish system self‑check. Prepare paper‑tube specimens cut to standard length, condition samples under specified temperature‑humidity environment. Select appropriate load‑range and configure compression‑speed on control panel.
2. Specimen Placement Position paper‑tube sample vertically and centred on lower press‑platen. Ensure the two end‑faces of tube keep full flat contact with upper‑and‑lower platens to avoid eccentric‑loading which would cause distorted test‑results.
3. Launch Compression‑Crush Test Trigger test‑start command. Motor‑driven upper platen descends at preset constant speed and applies vertical compression load onto paper‑tube. System continuously collects force‑signal until specimen reaches collapse point.
4. Data Review & Report Output Instrument captures peak crush‑strength value automatically. Read result from digital display. Complete repeated parallel‑specimen tests. Print inspection record by onboard thermal printer as required for lab‑file‑keeping.
5. Post‑Test Reset & Tidying Press platen automatically returns to original standby‑height. Remove crushed specimen fragments. Clear debris from platen surfaces. Shut‑off main power‑supply after finishing all test batches. Conduct periodic sensor‑calibration to sustain measuring‑reliability.
