Description

Technical Field

[0001] This utility model relates to the field of material testing equipment technology, specifically a benchtop multi-functional tensile testing machine. Background Technology

[0002] In the field of multi-category material testing, peel strength (such as fusible interlinings for clothing, composite fabrics, tapes, medical bandages, etc.) and sweater tensile strength (tensile properties under constant force conditions) are two key testing indicators. Currently, most tensile testing machines on the market are single-function designs: equipment for peel strength testing is only compatible with special fixtures and cannot meet the constant force control requirements of sweater tensile strength testing; equipment for sweater tensile strength testing, due to its fixed needle plate structure, is not compatible with peel testing of other materials.

[0003] This single-function design necessitates the configuration of multiple devices in the laboratory, increasing procurement costs and space requirements. Furthermore, it necessitates switching and debugging devices between different testing scenarios, resulting in cumbersome operations and low testing efficiency. Simultaneously, some devices lack data storage and remote control capabilities, requiring manual recording of test data, which is prone to errors and lacks real-time data interaction with computers. This makes it difficult to meet the demands of modern laboratories for testing accuracy, data traceability, and ease of operation. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a benchtop multi-functional tensile testing machine that can quickly switch between peel strength testing and sweater tensile strength testing without requiring complex mechanical modifications, thereby improving testing efficiency and equipment utilization.

[0005] The technical solution is as follows: A benchtop multi-functional tensile testing machine, characterized in that it includes a body, the top of which is provided with an elongated sliding groove and a fixing groove, a fixing block for connecting a tensile sensor is installed in the fixing groove, a slider is installed in the elongated sliding groove, the slider is connected to a drive mechanism installed inside the body, and threaded mounting holes are provided on both the fixing block and the slider, and a needle plate mechanism or a clamping mechanism is installed on the threaded mounting holes.

[0006] A further feature is that the drive mechanism includes a lead screw mechanism, one end of which is connected to a stepper motor via a pulley; The test needle plate mechanism includes a peel test stretch end needle plate mounted on the slider and a peel test fixed end needle plate mounted on the fixed block, or a sweater stretch end needle plate mounted on the slider and a sweater stretch fixed end needle plate mounted on the fixed block. The clamping mechanism is a composite fabric stretching end clamp mounted on the slider and a composite fabric fixing end clamp mounted on the fixing block, or a tape test stretching end clamp assembly mounted on the slider and a tape test fixing end stainless steel assembly mounted on the fixing block. The machine body is equipped with a drive module and a power module for driving the stepper motor; The outer wall of the machine body is equipped with a display screen; The elongated chute consists of two parallel chutes, and the fixed groove consists of two through grooves.

[0007] By adopting this utility model, a suitable needle plate mechanism or clamping mechanism can be selected and installed on the slider and the fixed block as needed. The item to be tested is placed on the needle plate mechanism or clamping mechanism, and the slider movement provides tension to the item, which is detected by the tension sensor. This realizes the switching between peel strength and sweater tensile strength testing. There is no need to configure multiple devices and complicated mechanical modifications, which improves the testing efficiency and equipment utilization, reduces laboratory costs, and saves space.

Detailed Implementation

[0009] See Figure 1 , Figure 2As shown, a benchtop multi-functional tensile testing machine includes a body 1. The top of the body 1 has an elongated sliding groove 4-5 and a fixing groove. A fixing block 4-10 connected to a tensile sensor 4-9 is installed in the fixing groove. A slider 4-6 is installed in the elongated sliding groove, and the slider 4-6 is connected to a drive mechanism installed inside the body. The drive mechanism includes a lead screw mechanism 4-4, one end of which is connected to a stepper motor 4-1 via a pulley 4-3. The stepper motor 4-1 is connected to a drive module 4-2, which is connected to a microcontroller module 4-7. The body 1 also contains a power module 4-8 for the stepper motor 4-1, drive module 4-2, tensile sensor 4-9, and microcontroller module 4-7. A display screen 3 is installed on the outer wall of the body 1. The elongated sliding groove 4-5 consists of two parallel sliding grooves, and the fixing groove consists of two through grooves. The machine adopts a benchtop design, is compact, and suitable for use on a laboratory desktop. A suitable microcontroller is used to meet the requirements of tensile data processing and multi-mechanism control; the tensile sensor is model L6C-C3-20kg-2B, with a range of 0-100N and an accuracy of 0.1%FS, ensuring the accuracy of tensile data acquisition; the stepper motor is model 57HBP56AL4-TCO, which, together with the lead screw, realizes the smooth linear movement of the slider, with a control accuracy of up to 0.01mm; the display screen is a 3.2-inch model COB12864, which supports synchronous display of values; in the power module, the large power supply is model S-100-24 (24V) and the small power supply is model JMD10-55T (5V).

[0010] Both the fixed block 4-10 and the slider 4-6 have threaded mounting holes 2, on which a needle plate mechanism or a clamping mechanism is mounted. The drive module 4-2 drives the stepper motor 4-1 to rotate at a predetermined speed and direction. The stepper motor 4-1 drives the lead screw 4-4 to rotate through the pulley 4-3. The lead screw 4-4 is threadedly engaged with the slider 4-6, causing the slider 4-6 mounted on the lead screw 4-4 to move the needle plate or clamp away from the needle plate or clamp on the fixed block at a uniform speed, thereby stretching the sample clamped at both ends.

[0011] The following section explains the different test pin plate mechanisms and fixture mechanisms.

[0012] See Figure 3 As shown, the test needle plate mechanism consists of a peel test tensile end needle plate 2-1-2 mounted on the slider 4-6 and a peel test fixed end needle plate 2-1-3 mounted on the fixed block 4-10. The sample made in conjunction with the sample tool 2-1-1, such as the two ends of an adhesive lining for clothing, is fixed on the peel test tensile end needle plate 2-1-2 and the peel test fixed end needle plate 2-1-3. The slider 4-6 moves at a constant speed to peel the sample. The tensile force can be measured by the tensile sensor 4-9 using the principle of force interaction.

[0013] See Figure 4 As shown, the clamping mechanism consists of a composite fabric stretching end clamp 2-2-2 mounted on the slider 4-6 and a composite fabric fixing end clamp 2-2-1 mounted on the fixing block 4-10. It can clamp both ends of the composite fabric to test the tensile strength of the composite fabric.

[0014] See Figure 5 As shown, the test needle plate mechanism consists of a sweater stretching end needle plate 2-3-2 mounted on slider 4-6 and a sweater stretching fixed end needle plate 2-3-1 mounted on fixed block 4-10. The sweater sample with the counted coils is aligned and installed on the needle plate. The sweater stretching end needle plate 2-3-2 moves to stretch the sweater, and the tension is measured by the tension sensor 4-9.

[0015] See Figure 6 As shown, the clamping mechanism consists of a tape test tension end clamping assembly 2-4-2 mounted on the slider 4-6 and a tape test fixed end stainless steel assembly 2-4-3 mounted on the fixed block 4-10. One end of the tape is attached to the tape test fixed end stainless steel assembly 2-4-3, and the tape test pressure roller 2-4-1 is used to press it repeatedly several times to make the tape stick to the tape test fixed end stainless steel assembly 2-4-3. Then, the tape test tension end clamping assembly 2-4-2 on the slider 4-6, which clamps the other end of the tape, moves, and the tension is measured by the tension sensor 4-9.
