Product Overview

The KR‑409 automatic cup‑body stiffness analyser is dedicated laboratory equipment for evaluating lateral bending‑resistance performance of disposable paper cups, paper bowls and similar paper‑made beverage containers. Driven by precision stepper‑motors, dual measuring probes apply controlled lateral displacement onto cup side‑walls; high‑precision force sensor captures the resistance load during cup‑body deformation. Stiffness readings quantify the cup’s anti‑collapse capacity, which helps manufacturers assess product resistance to squeezing and softening during handling and usage.

Designed following QB/T 2294‑2006, GB/T 2679.3 and JJG 157‑1995 requirements, this desktop unit is widely deployed by paper‑cup production plants, food‑packaging manufacturers, material‑R&D institutes and accredited third‑party QC laboratories for incoming‑material inspection, finished‑product release‑testing and paper‑formula comparative evaluation.

Core Product Competitive Advantages

1. Precision Dual‑Probe Motor‑Driven Transmission System High‑accuracy stepper‑motor controls forward‑backward travel of two symmetric measuring probes. It maintains standard test speed at (12.5 ± 1.2) mm/min and fixed relative probe displacement of (9.5 ± 0.2) mm. Minimised mechanical backlash ensures consistent movement trajectory for stable and repeatable test‑data across multiple specimen batches.
2. High‑Resolution Force‑Sensing Module Force‑sensor covers measuring range 1‑10 N with 0.01 N readout resolution. Indication error is controlled ≤0.1 % and indication variation ≤1 %. Delivers reliable stiffness‑force readings even for thin‑wall lightweight paper‑cup samples.
3. Intelligent MCU‑Controlled Full‑Automatic Test Workflow Microcontroller handles the complete sequence: probe motion control, real‑time force‑data acquisition, statistical calculation and result display. After reaching preset displacement threshold, probes automatically retract home. Operators avoid manual timing and reading‑recording work, lowering human‑induced error for high‑volume daily‑QC tasks.
4. Built‑In Thermal‑Printer For On‑Site Report Output Equipped with integrated thermal printing unit. Upon finishing each test group, maximum‑force, average‑value and deformation‑related data can be printed directly with test timestamp. No extra peripheral devices are needed for lab‑archiving and inspection‑report‑making.
5. Adjustable Specimen‑Stage & Compact Desktop Layout The specimen‑holding platform supports height adjustment, and probe‑to‑probe gap can be tuned within 40‑120 mm to fit cups / bowls of different calibres. Compact cabinet‑style body occupies little lab‑bench space. Clear front‑panel keys simplify operation for operators with limited instrument‑training background. Over‑force auto‑retract protection prevents sensor damage under overload‑conditions.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place instrument on stable, vibration‑free laboratory bench. Power‑on and run system self‑diagnosis. Condition paper‑cup specimens under standard temperature‑humidity environment. Adjust probe spacing and specimen‑platform height according to cup dimension, ensure probes contact roughly two‑thirds of cup‑body height.
2. Specimen Mounting Set paper‑cup sample centrally on the rotary specimen‑stage. Align cup side‑wall towards dual probes and secure sample position to prevent shifting during lateral‑loading process.
3. Start Automatic Stiffness Measurement Trigger test‑start command. Dual probes perform relative movement at standard speed and squeeze cup‑wall. Force‑sensor continuously records deformation‑resistance force. When reaching predefined travel limit, probes automatically retract back to standby‑position.
4. Data Review & Report Output Read peak‑stiffness value from LCD screen. Run multiple parallel‑specimen tests to obtain average‑value. Print inspection report with timestamp and statistical data via onboard thermal printer for filing purpose.
5. Post‑Test Tidying Remove tested paper‑cup specimen. Clear paper scraps from probe tips and specimen‑stage. Shut‑off main power‑supply after finishing test batches. Periodically verify force‑sensor accuracy to guarantee measuring‑credibility.
