Description

Technical Field

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

[0002] Polyester fabric, as a commonly used textile material, is widely used in clothing, home textiles, industrial filter cloth and other fields. In the production and application of polyester fabric, its elastic tensile properties are one of the key indicators for measuring product quality, which directly affects the durability, wearing comfort and subsequent processing adaptability of the fabric.

[0003] Currently, most existing polyester fabric elastic tensile testing devices on the market use relatively simple methods to fix the polyester fabric, usually just by squeezing and fixing it with a flat pressure plate. This fixing method is prone to causing the polyester fabric to slip during the testing process, especially when the tensile force gradually increases. The relative displacement between the fabric and the fixing mechanism will cause the test data to deviate and cannot accurately reflect the true elastic tensile performance of the polyester fabric. Utility Model Content

[0004] The purpose of this invention is to provide a polyester fabric elastic tensile testing device with the advantages of multiple locking and fixing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyester fabric elastic tensile testing device, comprising an operating platform, with lower positioning frames on both sides of the top of the operating platform, a tension sensor installed on the right side of the left lower positioning frame, a tension rope on the right side of the tension sensor connected to the right lower positioning frame, an upper positioning frame installed at the upper end of the lower positioning frame, an adjusting screw threadedly installed in the middle of the upper positioning frame, an arc-shaped pressure plate rotatably installed at the lower end of the adjusting screw, positioning teeth symmetrically installed on both sides of the bottom of the arc-shaped pressure plate, a fixing column installed at the bottom of the inner cavity of the lower positioning frame, locking grooves aligned with the positioning teeth being opened on both sides of the top of the fixing column, a limit protrusion longitudinally installed at the center of the top of the fixing column, an electric cylinder installed on the outside of the lower positioning frame, a side reinforcement plate installed at the outer end of the electric cylinder, and the lower end of the side reinforcement plate connected to the end of the operating platform.

[0006] As a preferred embodiment, a clamping plate is installed on the top of the outer side of the upper positioning frame, and a bearing plate is installed below the outer side of the through groove inside the lower positioning frame, with the clamping plate correspondingly positioned above the bearing plate.

[0007] As a preferred embodiment, guide rods are vertically installed on both sides of the top of the arc-shaped pressure plate, and the upper end of the guide rods passes through the upper positioning frame and extends to the outside.

[0008] As a preferred embodiment, a support frame is fixedly installed at the rear end of the operating platform, and the upper end of the support frame extends above the operating platform and is equipped with an electric push rod. A lighting lamp is installed at the output end of the electric push rod.

[0009] As a preferred embodiment, the bottom of the operating platform is fixedly equipped with support legs on all four sides, and the front and rear sides of the top of the operating platform are fixedly equipped with transverse slide bars. The upper end of the transverse slide bars is embedded in the lower positioning frame and slidably installed.

[0010] As a preferred embodiment, the top of the upper positioning frame has movable slots on both sides corresponding to the positions where the guide rod moves, and one end of the guide rod is located inside the movable slot and is slidably installed.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses the positioning teeth at the bottom of the arc-shaped pressure plate to engage with the locking groove at the top of the fixed column, combined with the positioning function of the limiting protrusion and the secondary fixation of the pressure plate and the bearing plate, to form a multi-fixation structure. This effectively prevents the polyester fabric from slipping or shifting during tensile testing, ensuring accurate and reliable test data. The side reinforcement plate firmly connects the electric cylinder to the operating platform, preventing the electric cylinder from shaking during operation. At the same time, the transverse slide bar guides the movement of the lower positioning frame, preventing it from shifting laterally. The entire device operates stably during tensile testing, reducing equipment wear and extending its service life.

[0013] 2. This utility model uses a guide rod that passes through the upper positioning frame and extends to the outside. This provides strict constraint on the movement trajectory of the arc-shaped pressure plate as it moves up and down with the adjusting screw. This effectively prevents the arc-shaped pressure plate from shifting laterally due to the rotation of the adjusting screw, ensuring that the positioning teeth at the bottom of the arc-shaped pressure plate can be accurately aligned with the locking groove on the fixing column. This ensures the smooth completion of the fabric fixing step and improves the fixing accuracy. The electric push rod can drive the lighting lamp to move freely vertically. The operator can precisely adjust the lighting lamp to the optimal lighting position in the detection area according to the detection needs. Whether focusing on the fabric stretching node or clearly reading the tension sensor data, the adjustment can be adapted to effectively cope with different detection angles and operational needs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example 1:

[0021] Please see Figure 1 As shown, this utility model provides a polyester fabric elastic tensile testing device, including an operating platform 1. Lower positioning frames 5 are provided on both sides of the top of the operating platform 1. A tension sensor 6 is installed on the right side of the left lower positioning frame 5. The tension rope on the right side of the tension sensor 6 is connected to the right lower positioning frame 5. An upper positioning frame 7 is installed at the upper end of the lower positioning frame 5. An adjusting screw 8 is threadedly installed in the middle of the upper positioning frame 7. An arc-shaped pressure plate 10 is rotatably installed at the lower end of the adjusting screw 8. Positioning teeth 11 are symmetrically installed on both sides of the bottom of the arc-shaped pressure plate 10. A fixing column 12 is installed at the bottom of the inner cavity of the lower positioning frame 5. Locking grooves 13 aligned with the positioning teeth 11 are opened on both sides of the top of the fixing column 12. A limit protrusion 14 is longitudinally installed at the center of the top of the fixing column 12. An electric cylinder 18 is installed on the outside of the lower positioning frame 5. A side reinforcement plate 17 is installed on the outer end of the electric cylinder 18. The lower end of the side reinforcement plate 17 is connected to the end of the operating platform 1.

[0022] In this technical solution, the positioning teeth 11 at the bottom of the arc-shaped pressure plate 10 engage with the locking groove 13 at the top of the fixed column 12. Combined with the positioning function of the limiting protrusion 14 and the secondary fixation of the pressure plate 15 and the bearing plate 16, a multi-fixing structure is formed, which can effectively prevent the polyester fabric from slipping or shifting during the tensile testing process, ensuring accurate and reliable test data. The side reinforcement plate 17 firmly connects the electric cylinder 18 to the operating platform 1, preventing the electric cylinder 18 from shaking during operation. At the same time, the transverse slide bar 20 guides the movement of the lower positioning frame 5, preventing it from shifting laterally. The entire device operates stably during the tensile testing process, reducing equipment wear and extending its service life.

[0023] Example 2:

[0024] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, a clamping plate 15 is installed on the top of the outer side of the upper positioning frame 7, and a bearing plate 16 is installed below the outer side of the through groove inside the lower positioning frame 5. The clamping plate 15 is correspondingly positioned above the bearing plate 16.

[0025] Adopting such Figure 1 The technical solution shown uses the clamping plate 15 and the bearing plate 16 to clamp the edge of the fabric from above and below, which can effectively prevent the edge of the fabric from lifting or shifting during the stretching process. By simultaneously clamping the edge of the fabric, the phenomenon of local force concentration on the fabric can be reduced, and the tensile force can be transmitted more evenly to the whole fabric, avoiding the deviation of test data caused by loose edges and improving the accuracy of elastic tensile test results.

[0026] Secondly, in the technical solution, guide rods 9 are vertically installed on both sides of the top of the arc-shaped pressure plate 10. The upper end of the guide rods 9 passes through the upper positioning frame 7 and extends to the outside. A support frame 2 is fixedly installed at the rear end of the operating platform 1. The upper end of the support frame 2 extends to the top of the operating platform 1 and is equipped with an electric push rod 3. A lighting lamp 4 is installed at the output end of the electric push rod 3.

[0027] Its adoption is as follows Figure 1 The technical solution shown has a guide rod 9 that passes through the upper positioning frame 7 and extends to the outside. It can strictly constrain the movement trajectory of the arc-shaped pressure plate 10 as it moves up and down with the adjusting screw 8, effectively preventing the arc-shaped pressure plate 10 from shifting laterally due to the rotation of the adjusting screw 8. This ensures that the positioning teeth 11 at the bottom of the arc-shaped pressure plate 10 can be accurately aligned with the locking groove 13 on the fixing column 12, ensuring the smooth completion of the fabric fixing step and improving the fixing accuracy. The electric push rod 3 can drive the lighting lamp 4 to move freely vertically. The operator can accurately adjust the lighting lamp 4 to the best lighting position in the detection area according to the detection requirements. Whether focusing on the fabric stretching node or clearly reading the data from the tension sensor 6, it can be adapted through adjustment, effectively coping with different detection angles and operational requirements.

[0028] Example 3:

[0029] This utility model is as follows Figures 1-3 As shown, the bottom of the operating platform 1 is fixedly equipped with support legs 19 on all four sides, and the front and rear sides of the top of the operating platform 1 are fixedly equipped with horizontal slide bars 20. The upper end of the horizontal slide bar 20 is embedded in the lower positioning frame 5 and slidably installed. The upper positioning frame 7 has moving slots on both sides of the top and corresponding to the moving position of the guide rod 9. One end of the guide rod 9 is located in the moving slot and slidably installed.

[0030] By adopting the above technical solution, the transverse slide bar 20 can strictly constrain the movement direction of the lower positioning frame 5, ensuring that the lower positioning frame 5 moves only in a transverse straight line under the drive of the electric cylinder 18, avoiding its front-to-back offset or rotation, preventing the distortion of detection data due to the deviation of the stretching direction, and improving the reliability of the detection results; the moving groove is opened at the corresponding position of the guide rod 9, which can provide the guide rod 9 with dedicated moving space, avoiding the guide rod 9 from swaying or offseting left and right when it moves up and down with the arc-shaped pressure plate 10, and further strengthening the guiding effect on the arc-shaped pressure plate 10.

[0031] The working principle of this utility model is as follows: The two ends of the polyester fabric to be tested are placed on the fixing posts 12 of the lower positioning frame 5 on both sides, so that the middle part of the polyester fabric fits against the limiting protrusion 14. The limiting protrusion 14 can play a preliminary positioning role for the fabric. Then, the adjusting screw 8 is rotated. The adjusting screw 8 moves downward through the thread engagement with the upper positioning frame 7, which drives the arc-shaped pressure plate 10 to move downward synchronously until the positioning teeth 11 at the bottom of the arc-shaped pressure plate 10 are embedded in the locking groove 13. Through the engagement of the positioning teeth 11 and the locking groove 13, the polyester fabric is firmly fixed. At the same time, the pressing plate 15 on the outside of the upper positioning frame 7 and the bearing plate 16 inside the lower positioning frame 5 are firmly engaged to press the edge of the polyester fabric a second time, further improving the fixing effect.

[0032] The electric cylinder 18 is activated, which drives the lower positioning frames 5 on both sides to move in opposite directions along the horizontal slide bar 20 at the top of the operating platform 1, stretching the polyester fabric. The tension sensor 6 is connected to the lower positioning frame 5 on the right side through a tension rope. During the stretching process, the tension sensor 6 detects the magnitude of the tensile force in real time and transmits the data to an external display device for the operator to record and analyze. If the ambient light is insufficient during the test, the electric push rod 3 can be activated to adjust the vertical height of the lighting lamp 4 so that the lighting lamp 4 is aimed at the test area, providing the operator with a clear field of vision and ensuring the smooth progress of the test.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
