The finished shoe bending resistance testing machine is a core equipment used in the footwear manufacturing industry to evaluate the fatigue resistance performance of the sole, upper, and seams. Its design characteristics directly affect the testing accuracy and operational safety, and a scientific maintenance plan is the key to ensuring the long-term stable operation of the equipment. The following analysis will be conducted from two aspects: design features and maintenance plans.

1、 Design feature: Balancing functionality and safety

Modular structure and adjustable parameters

Modern testing machines generally adopt a dual station or six station design, supporting simultaneous testing of multiple pairs of shoes and improving efficiency. for exampleCS-6050DThe model is adjusted in front and back position through a screw fixture, which can be adapted to different shoe sizes（18-45Code); Bending angle（0°-90°）Frequency（50-300time/Both minutes and speed can be passedPLCFlexible setting of control system or touch screen to meet the requirementsSATRA TM92TheGB/T 3903.1Waiting for domestic and international standards.

High precision transmission and low-noise design

The combination of mechanical eccentric bearings and precision variable frequency motors ensures smooth bending action without impact, reducing testing errors. Some models (such asENThe shoe sole bending test machine adopts a crank connecting rod mechanism to simulate the dynamic stress distribution during human foot walking, and the test data is closer to the actual usage scenario. The operating noise of the equipment is lower than60Decibel, in compliance with industrial environmental requirements.

Safety protection and humanized operation

The transparent protective cover is equipped with an open stop sensing device to prevent operators from accidentally touching the dangerous area;LEDThe display box supports menu operations in both Chinese and English, simplifying the parameter setting process. For example,CS-6050DThe protective cover of the model adopts impact resistancePCThe material, combined with the emergency stop button, forms a dual safety guarantee.

Corrosion resistant materials and long-life design

The mechanical components are made of non corrosive structural aluminum and stainless steel, and the surface is treated with DuPont powder electrostatic spraying, which is resistant to moisture and chemical corrosion. High precision bearings and lubrication free transmission system reduce maintenance frequency and extend equipment service life to10Years or more.

2、 Maintenance plan: Emphasize both preventive maintenance and troubleshooting

Daily cleaning and inspection

Cleaning: After each test, wipe the fixture, protective cover, and control panel with a dry cloth to avoid dust accumulation that may affect sensor accuracy.

Inspection: Confirm that the power cord is not damaged and the fuse specifications match (usually5A/250V）The emergency stop button reset is normal.

Regular lubrication and component replacement

Bearing lubrication: every3Add lithium based grease to the transmission bearings every month to reduce wear.

Fixture adjustment: every6Check the wear of the fixture every month, replace deformed or loose screws and clamps, and ensure stable fixation.

Belt maintenance: If the equipment uses belt transmission, the belt tension should be checked monthly to avoid slipping or breakage.

Sensor calibration and data validation

Angle sensor: Use a standard protractor to calibrate the bending angle every year, and the error should be controlled within±1°Within.

Counter verification: By manually counting and comparing with the device display value, ensure accurate recording of bending times.

Temperature control: If the device is equipped with heating function, the accuracy of the temperature controller should be checked regularly to avoid changes in shoe material performance caused by high temperature.

Emergency handling of faults

Unable to start: Check the status of the power supply, fuse, and emergency stop button.

Bending abnormality: Adjust the fixture position and confirm that the shoe size matches the test parameters.

Excessive noise: Check the lubrication condition of the bearings and replace worn parts.

3、 Application Value and Industry Trends

The design evolution and maintenance optimization of the bending resistance testing machine for finished shoes directly promote the improvement of quality control level in the footwear industry. In the future, with the development of IoT technology, devices will integrate remote monitoring and data analysis functions to achieve automatic optimization of testing parameters and fault warning. For example, by uploading real-time bending times and crack propagation data to the cloud through sensors, combined withAIAlgorithms predict the lifespan of shoe materials, providing accurate basis for product development.

Through scientific design and maintenance, the finished shoe bending resistance testing machine can not only efficiently complete bending resistance performance testing, but also become an important tool for shoe companies to enhance product competitiveness and shorten research and development cycles.
