Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and more specifically, it relates to a tensile property testing device for fabric processing. Background Technology

[0002] A fabric tensile property testing device is an instrument specifically designed to evaluate the mechanical properties of textile fabrics under tensile stress. It measures parameters such as strength and elongation of the fabric throughout the entire process from stress to breakage by applying a controlled tensile load, thereby determining its key performance indicators such as strength, extensibility, and elastic recovery.

[0003] Existing tensile property testing devices for fabric processing suffer from slippage when used because the smooth surface of fabrics (such as polyester, nylon, and silk) results in insufficient friction. This slippage leads to lower measured breaking strength or even failure to record the true peak force, thus reducing the accuracy of the test results.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tensile performance testing device for fabric processing, which aims to solve the technical problem that the non-fixed fabric clamping affects the test results.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tensile performance testing device for fabric processing, comprising a base, a support plate fixedly installed on the upper left side of the base, a feeding roller movably connected to the upper left side of the support plate, a vertical plate fixedly installed on the upper right side of the base, a first electric cylinder fixedly installed on the middle right side of the vertical plate, a movable plate fixedly installed at the output end of the first electric cylinder, a pressing roller fixedly installed on the left side of the movable plate, a pressure sensor and a displacement sensor fixedly installed on the front and rear sides of the left side of the movable plate, a U-shaped groove opened on the right side of the support plate, a rubber plate fixedly installed on both the upper and lower sides of the right side of the support plate, three semi-circular grooves opened on the right side of the rubber plate, a second electric cylinder fixedly installed on both the upper and lower sides of the right side of the vertical plate, a rubber pressure plate fixedly installed at the output end of the second electric cylinder, and three rubber semi-circular pressure blocks fixedly installed on the left side of the rubber pressure plate.

[0007] The present invention is further configured such that a guide roller is movably connected to the upper end of the support plate.

[0008] The present invention is further configured such that the extrusion roller is located between the upper and lower rubber pressure plates.

[0009] The present invention is further configured such that the support plate and the upright plate maintain a parallel positional relationship.

[0010] In summary, this utility model has the following beneficial effects:

[0011] By setting a rubber plate with a semi-circular groove on the support plate and a rubber pressure plate with a rubber semi-circular pressure block driven by a second electric cylinder on the upright plate, a multi-point encircling clamping structure is formed with corresponding upper and lower parts. When the rubber semi-circular pressure block presses against the fabric and cooperates with the semi-circular groove, the high coefficient of friction and elastic deformation capacity of the rubber material are used to apply a uniform and firm clamping force to the fabric sample. This structure significantly increases the clamping contact area and friction, and is particularly suitable for smooth and slippery fabrics such as polyester, nylon, and silk. It fundamentally solves the problem of sample slippage caused by insecure clamping in the existing technology, ensuring that the tensile force can be effectively transmitted to the sample, thereby accurately measuring the true peak breaking strength and greatly improving the accuracy and reliability of the test results.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A tensile property testing device for fabric processing, such as Figures 1 to 3 As shown, the system includes a base 1, a support plate 2 fixedly mounted on the upper left side of the base 1, a feeding roller 3 movably connected to the upper left side of the support plate 2, a vertical plate 4 fixedly mounted on the upper right side of the base 1, a first electric cylinder 5 fixedly mounted on the middle right side of the vertical plate 4, a movable plate 6 fixedly mounted on the output end of the first electric cylinder 5, a pressing roller 7 fixedly mounted on the left side of the movable plate 6, a pressure sensor 8 and a displacement sensor 9 fixedly mounted on the front and rear sides of the left side of the movable plate 6, a U-shaped groove 10 opened on the right side of the support plate 2, a rubber plate 11 fixedly mounted on both the upper and lower sides of the right side of the support plate 2, three semi-circular grooves 12 opened on the right side of the rubber plate 11, and a second electric cylinder 13 fixedly mounted on both the upper and lower sides of the right side of the vertical plate 4. A rubber pressure plate 14 is fixedly installed at the output end of the two electric cylinders 13. Three rubber semi-circular pressure blocks 15 are fixedly installed at the left end of the rubber pressure plate 14. The clamping components (rubber plate 11, rubber pressure plate 14, and rubber semi-circular pressure blocks 15) are all made of flexible rubber material. During the clamping process, the rubber material will undergo elastic deformation and achieve surface or line contact with the fabric surface, rather than point contact or hard extrusion of rigid metal clamps. This flexible clamping method can evenly distribute the clamping pressure, effectively avoiding crushing, cutting, or stress concentration on the edge or surface of the fabric, ensuring the integrity of the sample in the non-test area, making the fracture more likely to occur in the middle of the sample, meeting the standard test requirements, and further ensuring the validity of the test data.

[0021] like Figure 1 As shown, a guide roller 16 is movably connected to the upper end of the support plate 2. The guide roller 16 is located at the upper end of the support plate 2, providing a smooth transition path for the fabric and preventing the fabric from rubbing, scratching or wrinkling with the edge of the support plate 2 during movement.

[0022] like Figure 1As shown, the extrusion roller 7 is located between the upper and lower rubber pressure plates 14. When the upper and lower rubber pressure plates 14 clamp the fabric sample, the entire clamping area forms a stable "clamping point". By precisely setting the extrusion roller 7, which applies tensile force, in the middle position of this upper and lower clamping point, it can be ensured that the line of action of the tensile force (i.e. the direction of the push of the first electric cylinder 5) is perpendicular to and passes through the center line of the clamping area.

[0023] The support plate 2 and the upright plate 4 are kept in a parallel position.

[0024] Working principle: The feed roller 3 is driven by the click behind the feed roller 3 to feed the fabric. Then, it contacts the guide roller 16 and guides the fabric vertically to the right side of the support plate 2 and the left side of the extrusion roller 7. When it is necessary to clamp and fix the fabric sample, the upper and lower second electric cylinders 13 are activated. The output end of the second electric cylinder 13 pushes the rubber pressure plate 14 to move to the left, which in turn drives the rubber semi-circular pressure block 15 to press against the fabric sample. Since the rubber pressure plate 14 and the rubber semi-circular pressure block 15 are both made of rubber material, they have good elasticity and friction performance. When the three rubber semi-circular pressure blocks 15 contact and press against the fabric sample, they work together with the three corresponding semi-circular grooves 12 on the rubber plate 11 to form three local and tight ring-shaped clamping points. This multi-point ring-shaped structure significantly increases the clamping contact area and friction, effectively preventing the smooth fabric from slipping during the test.

[0025] After clamping is complete, the first electric cylinder 5 is activated. The output end of the first electric cylinder 5 pushes the movable plate 6 to move to the left. The movable plate 6 drives the extrusion roller 7 to move to the left synchronously. The extrusion roller 7 applies a tensile force to the clamped and fixed fabric sample, causing it to undergo tensile deformation. During this process, the pressure sensor 8 and displacement sensor 9, fixed on the movable plate 6, are connected to an external power source via a power cord. The pressure sensor 8 is a force sensor, typically employing the strain gauge principle, with tiny metal strain gauges attached inside. When the pressure sensor 8 is subjected to an external force (i.e., the reaction force generated when the movable plate 6 drives the extrusion roller 7 to stretch the fabric), the pressure sensor detects the change in pressure. The elastic body of sensor 8 undergoes a slight deformation, causing the strain gauge to deform accordingly. The resistance value of the strain gauge changes due to the deformation. This change in resistance is converted into a weak voltage signal output through a Wheatstone bridge circuit. Displacement sensor 9 monitors and records the displacement of the extrusion roller 7 in real time, which is the elongation of the fabric. By collecting the force and displacement data, the tensile performance curve of the fabric can be plotted, and its key performance parameters such as breaking strength and breaking elongation can be calculated. After the test is completed, the second electric cylinder 13 retracts, and the rubber pressure plate 14 and the rubber semi-circular pressure block 15 release their clamping on the fabric, making it easy to replace the new sample for the next test.

[0026] In summary, by setting a rubber plate 11 with a semi-circular groove 12 on the support plate 2 and a rubber pressure plate 14 with a rubber semi-circular pressure block 15 driven by the second electric cylinder 13 on the upright plate 4, a multi-point encircling clamping structure with corresponding upper and lower parts is formed. When the rubber semi-circular pressure block 15 presses against the fabric and cooperates with the semi-circular groove 12, the high coefficient of friction and elastic deformation capacity of the rubber material are used to apply a uniform and firm clamping force to the fabric sample. This structure significantly increases the clamping contact area and friction, and is particularly suitable for smooth and slippery fabrics such as polyester, nylon, and silk. It fundamentally solves the problem of sample slippage caused by insecure clamping in the prior art, ensuring that the tensile force can be effectively transmitted to the sample, thereby accurately measuring the true peak breaking strength and greatly improving the accuracy and reliability of the test results.

[0027] It is worth noting that the motor disclosed in the above embodiments is specifically a Panasonic MI NAS A6 series, the first electric cylinder 5 and the second electric cylinder 13 are specifically Festo EGC series, the pressure sensor 8 is specifically a HBM (Germany) U10M series, and the displacement sensor 9 is a HE IDENHAI N (Germany) LS series. The external control switch group and the external power supply control the operation of the motor, the first electric cylinder 5 and the second electric cylinder 13 adopt methods commonly used in the prior art.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
