Description

Technical Field

[0001] This invention belongs to the field of woven bag testing technology, specifically referring to a device for testing the abrasion resistance of woven bags. Background Technology

[0002] With the widespread application of new material technologies in plastic products such as woven bags, the testing of their wear resistance before leaving the factory has become particularly urgent and necessary.

[0003] Traditional testing methods typically use empty or cut woven bag samples for outer wall testing. However, in actual use, the bag wall not only withstands friction from the external environment but also scratches and punctures caused by the relative movement of internal materials during transportation and handling. Existing testing equipment can only perform friction tests on the outer surface of the bag and cannot simulate the damage process of internal particles to the bag wall. Therefore, it is difficult to comprehensively evaluate the wear resistance of woven bags under actual use conditions. In addition, during actual transportation, vehicle bumps cause internal particles to generate high-frequency, small-amplitude impacts and dynamic scratches on the bag wall, including both normal impact force and tangential sliding friction. Existing testing equipment can only provide static sliding friction with constant pressure and constant speed, and cannot achieve the combined loading of dynamic impact and static friction, which is significantly different from the real transportation environment. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a device for testing the abrasion resistance of woven bags, which simulates actual working conditions and tests the abrasion resistance of the inner and outer walls of the woven bags simultaneously.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a woven bag abrasion resistance testing device, including a testing platform, a filling tensioning mechanism, an anti-shifting pressing mechanism, and a testing mechanism. A fixed frame is provided on the upper wall of the testing platform. The filling tensioning mechanism is located on one side of the fixed frame. A bidirectional moving component is provided on the fixed frame to drive two sets of anti-shifting pressing mechanisms to move synchronously in opposite directions. The anti-shifting pressing mechanism is located on the bidirectional moving component and is symmetrically arranged on both sides of the filling tensioning mechanism. The testing mechanism is symmetrically arranged on both sides of the filling tensioning mechanism and is located between the filling tensioning mechanism and the anti-shifting pressing mechanism. The filling tensioning mechanism includes a central fixed seat and tensioning components symmetrically arranged on both sides of the central fixed seat. A filling groove is opened on the upper wall of the central fixed seat. An elastic simulation element is fixedly covered on the top of the filling groove. The four sides of the elastic simulation element are fixedly connected to the four sides of the filling groove.

[0006] Furthermore, the detection mechanism includes a detection drive, an adjustment component, an upper detection frame, a lower detection frame, a fixed friction block, and an adjustable friction block. The detection drive is mounted on the detection platform, the adjustment component is mounted on the detection drive, and the upper and lower detection frames are mounted on the adjustment component. The upper and lower detection frames are symmetrically arranged on the upper and lower sides of the filling tensioning mechanism. A mounting rod is provided through the end of the upper detection frame, the fixed friction block is located at the upper end of the mounting rod, a vibrator is provided at the end of the upper detection frame, and a telescopic rod is provided at the bottom end of the vibrator. The telescopic rod slides through the end of the upper detection frame, and the adjustable friction block is located at the bottom end of the telescopic rod. The distance between the upper and lower detection frames is controlled by the adjustment component, so that the fixed friction block and the adjustable friction block respectively contact the outer surface of the bag. The vibrator drives the adjustable friction block to vibrate, simulating the dynamic impact of transportation bumps, realizing a combined loading of dynamic impact and static friction, closely resembling actual transportation conditions, and improving detection reliability.

[0007] More specifically, the upper end of the filling groove is provided with an installation groove along the circumference. The elastic simulation component includes an installation frame, an elastic base layer, and a simulation medium block. The installation frame is fixedly disposed in the installation groove and is fixedly connected to the installation groove by bolts. The elastic base layer is disposed in the installation frame, and the simulation medium block is fixedly adhered to the upper wall of the elastic base layer.

[0008] After the woven bag is placed outside the central fixed seat, the woven bag is stretched and tightened by the tensioning component. The inner wall of the woven bag is in contact with the simulated medium block, simulating the continuous scraping and micro-puncture of the bag wall by hard particles. The simulated medium block is set with different hardness and different particle size. By changing the elastic simulation component with different hardness and particle size of the simulated medium block, it is easy to simulate the wear of the inner surface under practical working conditions, which significantly improves the authenticity of the test.

[0009] Preferably, the tensioning assembly includes a tensioning bidirectional screw, a tensioning sleeve, a tensioning hinge, a mounting base, a roller frame, and a tensioning roller. The central fixed base has symmetrically arranged tensioning cavities on both sides, which are positioned along the length of the central fixed base. The tensioning bidirectional screw is rotatably disposed within the tensioning cavity, and its two ends are symmetrically provided with threads of opposite directions. The tensioning sleeves are symmetrically slidably disposed within the tensioning cavity, and the two tensioning sleeves are threadedly connected to the two ends of the tensioning bidirectional screw. The two ends of the tensioning hinge are hinged to the tensioning sleeve and the mounting base, respectively, and the tensioning hinges are symmetrically arranged. The mounting base is positioned between the two tensioning hinges. The roller frame is mounted on the side wall of the mounting base, and the tensioning roller is rotatably mounted on the roller frame.

[0010] Furthermore, the anti-slip clamping mechanism includes a clamping frame and symmetrically arranged clamping swing members. The bottom wall of the clamping frame is symmetrically provided with clamping hinge seats. The upper end of the clamping swing member is rotatably connected to the clamping hinge seat. The two ends of the clamping frame are symmetrically provided with extension plates. A spring is provided between the extension plate and the clamping swing member. The clamping swing member is inclined in a direction away from the center of the clamping frame. When the clamping frame moves towards the central fixed seat, the inclined clamping swing member contacts the bag body and rotates around the hinge seat. The spring provides a restoring force to make the clamping swing member press against the edge of the bag body, which is adaptive elastic clamping, effectively preventing the bag body from slipping and wrinkling, and ensuring the stability of the friction process.

[0011] More specifically, the clamping component includes a swing arm and a clamping shaft, the clamping shaft is fixedly disposed at the bottom end of the swing arm, and the outside of the clamping shaft is fixedly covered with an anti-slip layer.

[0012] Preferably, the diameter of the tensioning roller is equal to the thickness of the central fixed seat, ensuring that the inner surface of the woven bag fits against the upper and lower walls of the central fixed seat after it is stretched, eliminating gaps and wrinkles, and ensuring stable and reliable frictional contact.

[0013] As a further improvement to this solution, the roller frame is slidably mounted on the side wall of the mounting base, and a tension spring is provided between the roller frame and the mounting base. The tension spring provides elastic cushioning to avoid rigid expansion that could cause local tearing of the woven bag.

[0014] Furthermore, the fixed base is provided with a drive cavity, and the drive cavity is provided with a synchronous drive assembly. The synchronous drive assembly includes a dual-axis motor and bevel gear sets symmetrically arranged at both ends of the dual-axis motor. The dual-axis motor is located in the drive cavity. The bevel gear sets include a driving bevel gear and a driven bevel gear. The output end of the dual-axis motor is coaxially fixedly connected to the driving bevel gear. The driven bevel gear is coaxially fixedly connected to the tensioning bidirectional screw. The driving bevel gear meshes with the driven bevel gear. The dual-axis motor drives the driving bevel gear to rotate. The driving bevel gear drives the tensioning screw to rotate through the driven bevel gear. Through the dual-axis motor and the symmetrically arranged bevel gear sets, the two symmetrically arranged tensioning components can be driven to move synchronously, so as to realize that the two sets of tensioning components expand or retract synchronously to tension the woven bag. The tensioning action is highly synchronized, the left and right tension of the bag is consistent, avoiding skewing and slippage, and improving clamping consistency.

[0015] The detection drive includes an electric slide table one and an electric slide table two. The electric slide table one is disposed on the detection table and is arranged along the length direction of the filling tensioning mechanism. The electric slide table two is disposed on the electric slide table one and is arranged along the width direction of the filling tensioning mechanism. The adjustment component is disposed on the electric slide table two.

[0016] More specifically, the adjustment assembly includes an adjustment bracket, a bidirectional adjustment screw, and an adjustment slide. The adjustment bracket is mounted on the electric slide table, the bidirectional adjustment screw is rotatably mounted on the adjustment bracket, the adjustment bracket has a guide shaft arranged parallel to the bidirectional adjustment screw, the adjustment slide is symmetrically slidably mounted on the guide shaft, the two ends of the bidirectional adjustment screw are symmetrically provided with threads of opposite directions, the two symmetrical adjustment slides are respectively threaded to the two ends of the bidirectional adjustment screw, and the upper detection frame and the lower detection frame are respectively connected to the two adjustment slides.

[0017] As a further improvement to this solution, a pressure sensor is provided between the fixed friction block and the mounting rod, and a touch panel is provided on the detection platform.

[0018] Preferably, two sets of symmetrically arranged anti-slip pressing mechanisms are each equipped with an adjusting slide, and the adjusting slide is equipped with an image recognition mechanism. The image recognition mechanism on the lower anti-slip pressing mechanism is equipped with a supplementary light. The detection platform is equipped with a controller, which is electrically connected to the pressure sensor, the touch panel, and the image recognition mechanism. The supplementary light provides uniform illumination. The image recognition mechanism collects images of the bag surface in real time and transmits them to the controller to automatically identify defects such as damage, pilling, and thinning.

[0019] Furthermore, the bidirectional moving assembly includes a clamping motor, a clamping bidirectional screw, and a clamping screw seat. The testing platform is provided with a cover. The clamping bidirectional screw is rotatably disposed within the cover. The two ends of the clamping bidirectional screw are symmetrically provided with threads of opposite directions. The clamping screw seats are symmetrically slidably disposed within the cover. The two clamping screw seats are respectively threadedly connected to the two ends of the clamping bidirectional screw. An opening is provided on the side wall of the cover. A clamping connecting plate is provided on the side wall of the clamping frame. The end of the clamping connecting plate passes through the opening and is connected to the clamping screw seat. The clamping motor is disposed on the side wall of the cover. A belt drive assembly is provided between the output shaft of the clamping motor and the clamping bidirectional screw.

[0020] Preferably, the housing is provided with two bidirectional clamping screws, and a second belt drive assembly is provided between the two bidirectional clamping screws. The first belt drive assembly includes a main pulley, a driven pulley, and a drive belt. The main pulley is coaxially connected to the output shaft of the clamping motor, and the driven pulley is coaxially connected to the bidirectional clamping screws. The drive belt is wound around the outside of the main pulley and the driven pulley, and the drive belt is driven by gear meshing with the main pulley and the driven pulley. The first belt drive assembly and the second belt drive assembly have the same structure.

[0021] Furthermore, the telescopic rod includes a threaded outer sleeve and an inner screw. By turning the inner screw, the length of the telescopic rod can be adjusted, thereby adjusting the depth to which the adjustable friction block causes the woven bag to sink downward.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The internal scraping and external friction are integrated into the same detection mechanism. The fixed friction block contacts the outer surface of the bag from below to provide stable external friction, while the adjustable friction block presses down on the woven bag from above, so that the inner wall of the woven bag contacts the elastic simulation part. Together with the vibrator and the elastic simulation part, the dynamic scraping of internal particles is simulated. The vibrator drives the adjustable friction block to generate vertical vibration to simulate the dynamic impact during transportation bumps. At the same time, it simulates external friction and internal scraping, which more comprehensively reflects the actual use conditions.

[0023] 2. Simulated media blocks of different hardness and particle size are adhered to the upper wall of the elastic base layer to simulate the scraping characteristics of different materials. The elastic simulation component simulates the real flow of loose granular materials, which more realistically reflects the flow and displacement behavior of loose granular materials under pressure in the bag. When the vibrator drives the adjustable friction block to vibrate, the simulated media block will undulate slightly with the vibration under the elastic support of the elastic base layer, simulating the dynamic process of granular materials rearranging and flowing under vibration, which is closer to the real transportation scenario.

[0024] 3. The woven bag, which is fitted on the outside of the middle fixed seat, is stretched from the inside to the outside by the tensioning component, so that the woven bag is in a tensioned state during the test. The bag body is flat and wrinkle-free, simulating the tension state after filling. This is consistent with the stress state of the bag body after actual filling, and the test results are more valuable. At the same time, a filling groove is opened on the upper wall of the middle fixed seat to place the elastic simulation component, so that the inner wall of the bag fits with the simulation medium block, simulating the scratching of the bag wall by the internal particles.

[0025] 4. Two sets of symmetrically arranged clamping ornaments simultaneously press the edge of the woven bag from two opposite directions, forming a bidirectional anti-slip force. This effectively resists the horizontal sliding tension during the abrasion resistance test, preventing the bag from deviating. The clamping ornaments, in conjunction with springs, achieve elastic clamping that adapts to changes in thickness, locking the edge of the woven bag to the side wall of the central fixed seat. This, in conjunction with the tensioning mechanism, ensures constant tension during the test.

[0026] 5. The elastic base layer adapts to deformation, the inner wall of the woven bag fits seamlessly with the simulated medium block, there are no dead angles for scraping, and the internal wear detection data is stable and has good repeatability. Attached Figure Description

Dual-shaft motor 30 drives the tensioning double-axis screws 20 on both sides of the middle fixed seat 7 to rotate through bevel gear sets symmetrically arranged at both ends. Each tensioning double-axis screw 20 drives the two tensioning sleeves 21 on it to move towards each other and get closer. The tensioning sleeves 21 push the mounting seat 23 to move outward away from the middle fixed seat 7 through the tensioning hinge 22. The mounting seat 23 drives the roller frame 24 and the tensioning roller 25 to expand outward, opening the woven bag from the inside. When the woven bag is evenly tensioned and the bag body is flat and wrinkle-free, the dual-shaft motor 30 stops. The diameter of the tensioning roller 25 is equal to the thickness of the middle fixed seat 7, ensuring that the inner surface of the woven bag is in contact with the upper and lower walls of the middle fixed seat 7 after tensioning, eliminating gaps and wrinkles.Then, the bidirectional moving component 6 is activated, driving the two anti-shifting clamping mechanisms 3 to move towards each other and approach the filling tensioning mechanism 2, thereby clamping and fixing the woven bag to be tested between the anti-shifting clamping mechanism 3 and the filling tensioning mechanism 2. The clamping motor 40 drives the two clamping bidirectional screws 41 to rotate synchronously through belt drive component one and belt drive component two 45. The clamping bidirectional screws 41 drive the symmetrically arranged clamping screw seats 42 to move towards each other and approach. The clamping screw seats 42 drive the two anti-shifting clamping mechanisms 3 to move towards each other and approach the filling tensioning mechanism 2 through the clamping connecting plate 44. When the clamping pendant 34 is in contact with the woven bag, as the clamping screw seats 42 drive the anti-shifting clamping mechanisms 3 to continue moving towards the filling tensioning mechanism 2, the filling tensioning mechanism 2 pushes the clamping pendant 34 to rotate upward. When the pressing motor 40 stops operating, under the restoring force of the spring 37, the pressing swing member 34 presses the edge of the woven bag tightly between the pressing shaft 39 and the middle fixed seat 7. The two sets of symmetrically arranged pressing swing members 34 press the edge of the woven bag simultaneously from two opposite directions, forming a bidirectional constraint, effectively resisting the horizontal sliding tension during the wear resistance test, and preventing the bag from deviating. The pressing swing member 34 locks the edge of the woven bag to the side wall of the middle fixed seat 7, maintaining the bag tension established by the tensioning component 8, and ensuring constant tension during the test. Then, the bidirectional adjusting screw 52 is turned, which drives the two adjusting slides 53 to move towards each other. The two adjusting slides 53 respectively drive the upper detection frame 13 and the lower detection frame 14 to move towards each other, approaching the middle fixed seat 7. When the fixed friction block 15 is in close contact with the lower surface of the woven bag, the pressure sensor 55 generates an electrical signal under pressure. The controller 60 controls the pressure sensor 55 between the fixed friction block 15 and the mounting rod 17 to monitor the contact pressure in real time and displays it on the touch panel 56. Observe the pressure sensor 55 value on the touch panel 56 to confirm that the pressure has reached the set value, and stop rotating the adjusting bidirectional screw 52. At this time, the adjustable friction block 16 has been pressed against the upper surface of the woven bag and pushed the upper surface of the woven bag downwards. The elastic base layer 63 undergoes elastic deformation, allowing the simulated medium block 10 to conform to the inner wall of the woven bag. If further adjustment of the pressing depth is required, the length of the telescopic rod 19 can be adjusted by turning the inner screw to change the extension length of the adjustable friction block 16. Adjusting the adjustable friction block 16 to push the woven bag downwards, then starting the vibrator 18, and selecting the sliding direction according to the testing needs, when only the electric slide table 49 is started, the electric slide table 49 drives the adjustable friction block 16 and the fixed friction block 15 to slide back and forth along the length direction of the middle fixed seat 7, simulating external wear, which is convenient for testing the wear resistance of the woven bag in the first direction. When only the electric slide table 50 is started, the electric slide table 50 drives the adjustable friction block 16 and the fixed friction block 15 to slide back and forth along the width direction of the middle fixed seat 7, simulating external wear, which is convenient for testing the wear resistance of the woven bag in the second direction. When both the electric slide table 49 and the electric slide table 50 are started at the same time, a compound motion in two directions is achieved to simulate an irregular wear trajectory.The vibrator 18 drives the adjustable friction block 16 to generate vertical vibration. The elastic base layer 63 causes the simulated medium block 10 to conform to the deformation of the woven bag, so that the simulated medium block 10 applies pressure from the inside of the bag and slides relative to it, simulating the dynamic scraping and impact of the internal filling material on the inner wall of the woven bag. Combined with the horizontal sliding of the adjustable friction block 16, it realizes the real composite wear condition that cannot be reproduced by traditional static or single external friction detection. At the same time, the fixed friction block 15 below provides stable external friction, which together with the dynamic scraping of the adjustable friction block 16 above constitutes synchronous loading inside and outside. The supplementary light 59 provides... Provides uniform illumination. The image recognition mechanism 58 collects images of the bag surface in real time and transmits them to the controller 60, automatically identifying defects such as damage, pilling, and thinning. After reaching the preset number of friction cycles or time, the vibrator 18, electric slide, pressure motor 40, and dual-axis motor 30 are stopped sequentially. The bidirectional adjusting screw 52 is turned in the reverse direction to reset the upper and lower detection frames 14. The pressure motor 40 is started in the reverse direction to move the anti-displacement pressure mechanism 3 away from the central fixed seat 7. Then, the dual-axis motor 30 is started in the reverse direction to retract the tension roller 25, loosening the woven bag. The woven bag can then be removed to complete the abrasion resistance test of the woven bag.
