WDS/WDW 01-05 Single column Universal testing machine

Product Application

The WDS/W-1 Digital Display Electronic Universal Testing Machine is suitable for testing the tensile properties of plastic films, composite films, soft packaging materials, adhesives, adhesive tapes, self-adhesive materials, rubber, paper, plastic-aluminum sheets, enameled wires, non-woven fabrics, textiles, waterproof materials, V-belts, and more. It can also perform tests such as 180-degree peel, 90-degree peel strength, heat seal strength, and constant elongation tests. With configuration changes, it can be widely used for other materials such as paper, synthetic fibers, metal wires, and metal foils, measuring film tensile strength, tensile strength, elongation, and breaking length. It can measure aluminum foil and aluminum-plastic tape's tensile strength, peel strength, and elongation. Additionally, it measures the tensile strength, elongation, and tensile elastic modulus of plastic films, as well as the heat seal strength, tensile strength, and peel strength of food packaging bags. It tests the adhesive strength, sealing edge strength, tensile strength, and elongation of sanitary napkins, the peel strength and tensile strength of pressure-sensitive adhesive tapes, and the breaking force and elongation of synthetic filament yarns. It also measures the smoothness of zippers.

General Description:

The WDS/W-01 microcomputer-controlled electronic universal testing machine consists of the main machine, fixture accessories, and an electrical measurement and control system.

5.1 Main Machine:

The main machine includes the upper and lower beams, middle beam, columns, transmission assembly, fully enclosed protective device, load sensor, and large deformation extensometer. The structure is formed by the upper and lower beams and columns. By moving the middle beam, it can perform tension, compression, and bending tests.

· Upper and Lower Beams, Middle Beam: Made from 45# alloy steel forging, ensuring the required rigidity of the equipment. Precision machining guarantees dimensional tolerance and form tolerance, providing a solid foundation for coaxiality and parallelism of the entire equipment. The surface undergoes sandblasting and primer spraying, followed by topcoat spraying for double protection.

· Columns: Made from surface-chromed hard alloy steel shafts, processed by CNC lathes to ensure overall rigidity of the frame, reducing external factors' impact on testing accuracy and thus ensuring testing precision.

· Transmission Assembly: Composed of a servo motor, synchronous pulley, synchronous belt, ball screw, etc. It adopts an arc synchronous toothed belt and ball screw transmission, ensuring smooth transmission and low noise. The specially designed reducer and precision ball screw drive the movement of the machine's crossbeam, achieving gapless transmission. The reducer replaces the synchronous pulley reduction device, making operation more stable, extending the synchronous belt's lifespan, reducing the frequency of belt replacement, greatly saving maintenance costs, and improving work efficiency.

· Fully Enclosed Protective Device: Provides comprehensive protection, ensuring operator safety. The surface is coated with plastic, which has strong adhesion, prevents rust, and is aesthetically pleasing.

· Load Sensor: Developed by our company, this load sensor is particularly suitable for use in electronic universal testing machines. It has low zero drift, high sensitivity, and adopts imported strain gauges, offering high insulation and stable repeatability. The exterior is nickel-plated.

· Large Deformation Extensometer: Equipped with two high-precision encoders, it eliminates the impact of the extensometer on the test results by adding counterweights, allowing for more accurate deformation measurement.

5.2 Fixture Accessories:

Standard configuration: One set of wedge-shaped tensile fixtures.

5.3 Electrical Measurement and Control System:

Capable of simultaneously configuring two load sensors, one motor, three encoders, one limit switch, and one printer. Users can replace them as needed. The software database structure is open-ended. Test data is managed using a database approach, with the option to save all test data and print outputs.
