Description

Technical Field

[0001] This utility model relates to the field of ramie fabric testing technology, specifically a testing device for ramie fabric. Background Technology

[0002] Ramie, as an important natural fiber, possesses numerous excellent properties such as good breathability, strong moisture absorption, and antibacterial and mildew-resistant characteristics, and is widely used in clothing, home textiles, and other fields. In the research and development and production of ramie fabrics, due to the varying quality and characteristics of different fabrics, the fiber fineness, strength, uniformity, fabric structure, and density have a crucial impact on the fabric's performance. To understand the various characteristic parameters of new fabrics, it is necessary to conduct various tests on ramie fabrics using testing equipment.

[0003] Among the various property tests, the tensile strength and abrasion resistance of fabrics are crucial and are mandatory test items. During the testing process, in order to prevent fabric displacement, the fabric needs to be clamped and fixed by a limiting structure. Traditional testing devices for fabric clamping mostly adopt clamp-type clamping structures. Since the fabric is thin, it is difficult to ensure the clamping stability and uniform force distribution of the fabric after clamping with traditional flat clamps. This can easily lead to deviations in test results due to localized force, affecting the accuracy of the test. Furthermore, for property testing, existing equipment can only perform single property tests, which is relatively limited in functionality. Therefore, a testing device for ramie fabric is proposed.

[0027] Example

[0028] Please see Figure 1-6 This utility model provides a technical solution: a testing device for ramie fabric, comprising a first testing mechanism and a second testing mechanism for testing ramie fabric, specifically:

[0029] The first testing mechanism is used for loading and tensile testing of ramie fabric. The first testing mechanism includes a support base 1, a channel rail support 2, a sliding platform 3, a fixed platform 4, a first cylinder 5, and a drive motor 6. The channel rail support 2 serves as a sliding guide support for the sliding platform 3, as shown in the attached diagram. Figure 3 As shown, the rail support 2 is fixedly fitted into the mounting slot in the middle of the support base 1 by bolts. The fixed platform 4 is fixedly installed on the upper rear side of the rail support 2. The sliding platform 3 is slidably installed on the upper part of the support base 1 by the rail support 2. In order to facilitate the guide support installation of the sliding platform 3, a guide rail is provided in parallel on the upper part of the rail support 2. The rail groove at the lower part of the sliding platform 3 is slidably fitted into the guide rail for support installation, which can improve the sliding stability of the sliding platform 3.

[0030] Both the sliding platform 3 and the fixed platform 4 have a loading roller 7 mounted on their upper parts via a drive motor 6. See attached diagram for details. Figure 3As shown, the drive motors 6 are arranged in pairs, each with its own reducer. The reducer is located on the drive side of the drive motor 6. The reducers of the two sets of drive motors 6 are fixedly installed on the sides of the sliding platform 3 and the fixed platform 4 respectively by bolts. The rotating shaft end of the drive motor 6 is fixedly installed to the drive input rotating shaft end of the reducer. In order to achieve the support and drive installation of the loading roller 7, as shown in the attached figure... Figure 5 As shown, a mounting column 9 is fixedly installed at the drive output shaft end of the reducer of the drive motor 6. The loading roller 7 is positioned and fitted into the upper part of the mounting column 9 through the slot. In order to improve the working support stability of the mounting column 9, an end shaft support 10 is fixedly installed in the connecting slot provided on the outer side of the sliding table 3 by bolts. The end shaft part of the mounting column 9 is rotatably supported and installed with the shaft hole part on the upper part of the end shaft support 10.

[0031] To facilitate the installation and positioning of the fabric end, a limiting groove block 8 is installed on the upper part of the feeding roller 7 through a slot, as shown in the attached figure. Figure 5 As shown, to facilitate the connection and installation of the limiting groove block 8, an installation groove 11 is axially opened through the outer periphery of the feeding roller 7. The limiting groove block 8 is fitted into the inner side of the installation groove 11. To achieve the installation limitation of the limiting groove block 8, limiting rubber strips 12 are fixedly installed on both sides of the limiting groove block 8. After installation, the limiting rubber strips 12 are fitted and snapped into the grooves on the inner side of the installation groove 11, which facilitates the disassembly and assembly of the limiting groove block 8. The fabric loading structure adopts a roller-wrap type, using two sets of feeding rollers 7 driven by the drive motor 6 as the fabric loading structure. During installation, the two sets of feeding rollers 7 driven by the drive motor 6 are used as the fabric loading structure. The limiting groove block 8 is used to lock and limit the end of the fabric. With the directional winding of the loading roller 7, the fabric is stably installed. After installation, the fabric is evenly distributed and subjected to uniform force, which is conducive to improving the accuracy of characteristic test results. After installation, the limiting groove block 8 is locked by the fabric wrapping limit to lock the end of the fabric. With the fabric wrapping friction, the loading stability of the fabric can be effectively improved. In order to facilitate the limiting connection of the end of the fabric, the limiting pins are evenly arranged at equal intervals in the lower part of the limiting groove block 8. After installation, the limiting pins are aligned and inserted into the pin holes on the bottom side of the mounting groove 11.

[0032] The first cylinder 5 is a high-thrust servo electric cylinder in the prior art. The first cylinder 5 is installed on the sliding drive side of the sliding stage 3 and is used for the sliding drive of the sliding stage 3. Specifically, see attached... Figure 2 As shown, the first cylinder 5 is fixedly installed on the rear middle of the fixed platform 4 by bolts. The push rod end of the first cylinder 5 moves through the fixed platform 4 and is fixedly installed on the rear middle of the sliding platform 3. In order to improve the accuracy of tensile force detection, a pressure sensor for thrust detection is set at the end rod connection of the first cylinder 5. While realizing the sliding drive of the sliding platform 3, it can provide tensile driving force for the tensile test of the fabric.

[0033] To prevent damage to the transmission part of drive motor 6 due to high torque, as shown in the attached... Figure 4 As shown, a locking screw seat 13 is fixedly installed on the side of the sliding stage 3. A locking bolt 14 is installed in the hole in the middle of the locking screw seat 13. After installation, the end of the locking bolt 14 passes through the locking screw seat 13 and is threaded into the screw hole on the upper part of the mounting column 9. When testing the tensile properties of thick fabric, the axial locking of the locking bolt 14 can ensure that the mounting column 9 is in a stable locking state.

[0034] The second testing mechanism is used for testing the abrasion resistance of the fabric. The second testing mechanism includes an edge support 15, a second cylinder 16, an end docking seat 17, and a testing end 18. The second cylinder 16 is vertically mounted in the middle of the support base 1, supported by the edge support 15. Specifically, see attached... Figure 6 As shown, the lower part of the side support 15 is fixedly installed to the side of the support base 1 by means of a slot fitting and bolt fastening. The second cylinder 16 is a servo electric cylinder in the prior art. The second cylinder 16 is fixedly installed to the top seat of the side support 15 by means of bolt fastening. The push rod end of the second cylinder 16 moves through the top seat of the side support 15. The end docking seat 17 is fixedly installed on the push rod end of the second cylinder 16. In order to realize contact pressure control detection, a pressure sensor is set in the slot in the middle of the bottom side of the end docking seat 17. In order to improve the stability of the moving support of the end docking seat 17, support guide columns 1 are fixedly installed on both sides of the upper part of the end docking seat 17. 9. The upper part of the support guide column 19 and the middle part of the top seat of the side support 15 are slidably connected and installed with the insertion hole. The structure is set up in an integrated manner for tensile and abrasion resistance testing. The two assembly roller columns 7 are driven by the drive motor 6. While limiting the winding of the fabric, the reciprocating lateral movement of the fabric can be realized through synchronous periodic rotation. In the limiting clamping state, it can form a tensile testing mechanism with the first cylinder 5 to complete the tensile characteristics testing of the fabric. In the rotation driving state, it can form an abrasion resistance testing mechanism with the second cylinder 16 to complete the abrasion resistance testing of the fabric. One machine can perform multiple functions and complete tensile and abrasion resistance testing with a single device, which greatly improves the functionality of the device.

[0035] The detection end 18 is detachably mounted to the push rod end of the second cylinder block 16 via the end docking seat 17, as detailed in the attached document. Figure 6 As shown, the upper part of the detection end 18 is positioned and fitted into the lower part of the end docking seat 17 through a slot. A limiting bolt 20 is installed in the limiting insertion hole in the middle of the end docking seat 17. The detection end 18 is fixedly installed in the lower part of the end docking seat 17 by the limiting bolt 20. Both the loading roller 7 and the detection end 18 adopt a detachable structure, which is convenient for disassembly and replacement. During operation, the loading roller 7 and the detection end 18 can be flexibly selected and replaced according to the detection requirements, which can meet the detection requirements of different types of fabrics and greatly improve the working flexibility of the device.

[0036] Working principle or structural principle: Before operation, the loading roller 7 and the detection end 18 are selected and installed according to the fabric size and detection requirements. When installing the fabric, the limiting pin at the bottom of the limiting groove 8 is inserted into the fabric end in a flat state. Then, the limiting groove 8 is installed into the inner side of the installation groove 11 by the fitting and pressing. After installation, the limiting groove 8 is installed and limited by the fitting and locking of the limiting rubber strip 12 with the inner edge groove of the installation groove 11. Then, the driving motor 6 is controlled by the operation panel to drive the loading roller 7 to rotate slowly. The fabric loading and installation are completed by directional winding. After installation, the limiting groove 8 is locked by the fabric wrapping and limiting self-locking to lock the fabric end. Combined with the fabric wrapping friction, the loading stability of the fabric can be effectively improved. The loading and installation of the other end of the fabric is completed in the same way, and the fabric installation work is completed.

[0037] During tensile testing, to avoid damage to the transmission structure of the drive motor 6 (for thick fabrics), after the fabric is loaded, two sets of locking pins 14 are installed into the holes in the middle of the locking screw seat 13 at the locking position. The mounting shaft 9 is locked in place by the fastening of the lower end of the locking pin 14 to the upper screw hole of the mounting shaft 9. Then, the first cylinder 5 drives the sliding stage 3 to move outward to tension the fabric and check the flatness of the fabric. After that, the first cylinder 5 drives the sliding stage 3 to move slowly and gradually apply tensile force until the fabric breaks. The tensile test is completed by recording the maximum tensile force.

[0038] During abrasion resistance testing, ensure that the locking pin 14 is in the removed state. After the fabric is loaded, the fabric is tensioned by the first cylinder 5. Then, the second cylinder 16 drives the detection end 18 to move down and contact the middle of the fabric. Set the testing parameters through the operation panel. Then, the two loading rollers 7 are driven by the drive motor 6 to rotate synchronously and periodically in the forward and reverse directions. The second cylinder 16 drives the detection end 18 to move down and maintain a periodically changing or constant contact pressure with the middle of the fabric. The abrasion resistance test of the fabric is completed through sliding friction.

[0039] In summary, this device employs a roller-wrap fabric loading structure, using two sets of loading rollers 7 driven by drive motor 6 as the fabric loading structure. During installation, limiting slots 8 are used to lock and limit the fabric ends, and the directional winding of the loading rollers 7 ensures stable fabric installation. After installation, the fabric is evenly distributed and subjected to uniform force, which is beneficial to improving the accuracy of characteristic test results. Furthermore, after installation, the limiting slots 8 are self-locking due to the fabric wrapping, effectively locking and limiting the fabric ends. Combined with the friction of the fabric wrapping, this effectively improves the stability of the fabric loading. The device adopts an integrated structure for tensile and abrasion resistance testing. The two loading rollers 7 are driven by drive motor 6, and while limiting the fabric winding, synchronous periodic rotation can achieve... The reciprocating lateral movement drive of the fabric, when in the limited clamping state, cooperates with the first cylinder 5 to form a tensile testing mechanism, completing the tensile property test of the fabric. When in the rotational driving state, it cooperates with the second cylinder 16 to form an abrasion resistance testing mechanism, completing the abrasion resistance test of the fabric. This multi-purpose device can complete tensile and abrasion resistance tests with a single unit, greatly improving the functionality of the device. The key components of the device adopt a modular structure. The feeding roller 7 and the testing end 18 are both designed for easy disassembly and replacement. During operation, the feeding roller 7 and the testing end 18 can be flexibly selected and replaced according to the testing requirements, which can meet the testing needs of different types of fabrics and greatly improve the working flexibility of the device.
