Description

Technical Field

[0001] The present invention relates to the technical field of glove testing, and specifically to a testing device for the abrasion resistance of the rubber surface of labor protection coated gloves. Background Art

[0002] In many labor-intensive industries and various work scenarios involving hand operations, labor protection coated gloves, as an important personal protective equipment, are widely used in fields such as construction, machinery manufacturing, logistics handling, and mining. Its main function is to protect the hands of workers from mechanical abrasion, cutting, stabbing, and chemical erosion. The abrasion resistance of the rubber surface of the gloves directly affects the service life and protective performance of the gloves. With the continuous progress of industrial technology, the production process of labor protection gloves has become increasingly complex, and new coating materials and formulations emerge in an endless stream, aiming to improve the comprehensive performance of the rubber surface of the gloves, such as abrasion resistance, anti-slip, acid and alkali resistance. However, the matching scientific, accurate, and efficient abrasion resistance testing technology has developed relatively slowly. Under the existing technology, an abrasion resistance test is carried out by contacting a rotatable friction roller with the labor protection gloves. The friction form is relatively single. In the logistics handling link, the packaging materials of goods are diverse, including cardboard boxes, wooden boxes, items wrapped in plastic film, etc. The fiber burrs on the surface of the cardboard box, the knots and textures of the wooden box, and the smooth and slightly sticky characteristics of the plastic film produce different friction effects on the gloves. The rotatable friction roller cannot simulate the unique friction characteristics of each packaging material and can only apply uniform and standardized sliding friction, unable to accurately capture the wear differences of the gloves when handling different packaged goods, resulting in enterprises being difficult to optimize glove products according to the test data to meet the actual needs of logistics handling.

[0003] The existing single friction roller test method cannot comprehensively cover and simulate the complex wear conditions of the gloves when contacting multiple substances in actual use in different industries. The reference value of the obtained test results is greatly reduced, making it difficult to effectively guide the research and development, production, and quality control of labor protection gloves. Therefore, we propose a testing device for the abrasion resistance of the rubber surface of labor protection coated gloves to solve the above problems. Summary of the Invention

[0019] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0020] Please refer to Figures 1-7 , the present invention provides a testing device for the abrasion resistance of the rubber surface of labor protection coated gloves. This device takes the workbench 1 as the core bearing platform. On one side of the workbench 1, a support base 2 is fixedly connected, and on the other side, a control panel 101 is integrated, and a scrap box 102 is configured on the top. On the side of the support base 2 facing the workbench 1, a guide rail 201 is fixedly installed. A moving table 202 is slidably connected to the guide rail 201. A hand mold base 203 is fixedly installed at the bottom of the moving table 202. The hand mold base 203 is used to sleeve the glove body 3 to be tested. A friction roller 5 is correspondingly arranged below the glove body 3. The friction roller 5 is connected to the fixed base 4 through a connection assembly 6. The fixed base 4 is fixed to the support base 2, and a motor 401 is installed on its back to drive the friction roller 5 to rotate.

[0021] The workbench 1 serves as a basic carrier for carrying various functional components and providing a stable testing platform. The support base 2 is vertically fixed on one side of the workbench 1, and its height and structural design ensure the overall stability. The control panel 101 integrates an operation interface and a control module for inputting test parameters and monitoring the operating state. The scrap box 102 is placed on the top of the workbench 1 for collecting the rubber surface debris generated during the test. Its position is adapted to the structure of the workbench 1 for easy cleaning.

[0022] The guide rail 201 inside the support base 2 provides a vertical movement track for the moving table 202. The moving table 202 can slide up and down along the guide rail 201, and its driving method (such as an electric push rod or a lead screw nut mechanism) is controlled by the control panel 101 to achieve precise height adjustment. The hand mold base 203 fixed to the bottom of the moving table 202 simulates the contour of the human hand, and its surface is designed to fit the shape of the glove socket, ensuring that the glove body 3 is firmly installed and the rubber surface is facing downwards and aligned with the friction roller 5.

[0023] Fixed seat 4 and power transmission structure The fixed seat 4 is fixed to the support base 2. An assembly window 404 is opened on its front surface for inserting the friction roller 5; a motor 401 is installed on the back. The motor 401 is connected to the fixed seat 4 through a fixing ring 402 to ensure the stability of power transmission. The driving roller 403 at the output end of the motor 401 is slidably connected to the driving groove 501 at the end of the friction roller 5. When the friction roller 5 is inserted into the assembly window 404, the driving roller 403 automatically fits into the driving groove 501 to form a power connection, enabling the motor 401 to drive the friction roller 5 to rotate.

[0024] Quick replacement connection component 6 On the surface of one end of the friction roller 5 close to the fixed seat 4, an assembly ring groove 601 is opened. A plurality of mounting seats 602 are evenly distributed circumferentially at the bottom of the ring groove. An installation window 603 is opened on one side of the mounting seat 602. Each mounting seat 602 houses a rotating roller 605, a coil spring 606, and a limit seat 607. Both ends of the rotating roller 605 are connected to the mounting seat 602 through the coil spring 606. Under normal conditions, the coil spring 606 pushes the limit seat 607 to protrude outwards; both sides of the limit seat 607 are inclined surfaces 608, which cooperate with the inner wall of the guide groove 609 at the edge of the assembly window 404 of the fixed seat 4.

[0025] Installation process of the friction roller 5 When replacing the friction roller 5, align it with the assembly window 404 of the fixed seat 4 and insert it. The mounting seat 602 slides along the guide groove 609. During the insertion process, the inner wall of the guide groove 609 presses against the inclined surface 608 of the limit seat 607. The rotating roller 605 inside the installation groove 604 is stressed, forcing the rotating roller 605 to compress the coil spring 606 and contract inward. The limit seat 607 is temporarily retracted into the assembly ring groove 601. When the mounting seat 602 slides to the limit groove 610 at the end of the guide groove 609, the elastic force of the coil spring 606 is released, pushing the limit seat 607 to snap into the limit groove 610, using the cooperation of the inclined surface 608 to achieve the locking connection between the friction roller 5 and the fixed seat 4. At the same time, the driving roller 403 and the driving groove 501 are docked to ensure power transmission.

[0026] Disassembly process of the friction roller 5 During disassembly, pull the friction roller 5 outwards. The limit seat 607 compresses the coil spring 606 under the guidance of the inclined surface 608 of the limit groove 610, disengages from the limit groove 610 and is received into the assembly ring groove 601. The mounting seat 602 slides reversely along the guide groove 609 until the friction roller 5 is completely separated from the fixed seat 4. The whole process does not require tools, achieving quick disassembly and assembly.

[0027] Glove sleeving: Control the lifting of the mobile platform 202 through the control panel 101, raise the hand mold base 203 to a convenient operating position, put the glove body 3 to be tested on the hand mold base 203, ensure that the rubber surface completely covers the surface of the hand mold base 203 and hangs down naturally. The glove wrist can be fixed by an elastic member to avoid displacement during testing.

[0028] Position calibration: Control the lowering of the mobile platform 202 to gradually bring the glove rubber surface close to the friction roller 5, and assist in alignment through vision or sensors to ensure that the center of the rubber surface is aligned with the center area of the surface of the friction roller 5, providing uniform contact conditions for subsequent testing.

[0029] Contact force and rotation speed setting: Input the target contact force (i.e., the pressure between the glove rubber surface and the friction roller 5) and the rotation speed of the friction roller 5 through the control panel 101. The contact force is adjusted by controlling the lowering amplitude of the mobile platform 202 or applying pressure, and the rotation speed is adjusted by the drive module of the motor 401. Both can be continuously adjusted within a certain range to simulate the wear conditions in different usage scenarios.

[0030] Test run: Start the motor 401, the friction roller 5 rotates driven by the drive roller 403, and at the same time, the mobile platform 202 maintains a constant contact force, so that the glove rubber surface continuously rubs against the surface of the friction roller 5. The debris generated during the test naturally falls into the waste debris box 102 on the top of the workbench 1, avoiding polluting the test environment.

[0031] The device supports replacing the friction roller 5 with different designs, including but not limited to friction rollers 5 with different textures (such as rigid and elastic materials), different surface structures (such as smooth, rough, and toothed surfaces), to simulate the wear conditions of gloves when contacting various substances such as metals, sands, and chemical coatings in industries such as construction, machinery, and chemical engineering. By quickly replacing the friction roller 5 and adjusting the contact force and rotation speed, various wear scenarios from extremely harsh to normal use can be covered to ensure that the test results are close to the actual application requirements.

[0032] The vertical movement accuracy of the mobile platform 202 directly affects the contact uniformity between the glove and the friction roller 5, and its drive system needs to have stable positioning ability to ensure that the contact force remains constant during the test. The shape design of the hand mold base 203 fits the characteristics of the human hand, making the rubber surface of the glove flat and stretched after sleeving, avoiding test errors caused by wrinkles or slack.

[0033] The connecting component 6 realizes the quick locking and reliable connection of the friction roller 5 through the elastic force of the coil spring 606 and the geometric fit of the limit seat 607 and the limit groove 610. During the rotation of the friction roller 5, the engaging structure of the limit seat 607 and the limit groove 610 bears the axial force, preventing the friction roller 5 from loosening and ensuring the stability of power transmission and the safety of the testing process.

[0034] The control panel 101 integrates sensor feedback and control algorithms, monitors parameters such as contact force and rotational speed in real time, and automatically adjusts the position of the moving table 202 and the output of the motor 401 according to the set values to achieve closed-loop control. The operation interface supports parameter presetting, data recording, and curve display, facilitating the operator to intuitively evaluate the testing process and results.

[0035] Regularly clean the surface of the guide rail 201 to ensure smooth sliding of the moving table 202 and avoid foreign object jamming affecting the height adjustment accuracy. Check the elasticity of the coil spring 606 and the wear condition of the limit seat 607. If it is found that the locking force decreases or the engagement is not smooth, replace the relevant components in time to ensure the reliability of the installation of the friction roller 5. After each test, clean the waste box 102 to keep the workbench 1 clean and avoid debris accumulation affecting subsequent tests.

[0036] By combining the replaceable friction roller 5 with intelligent control technology, this device breaks through the limitations of traditional single wear tests, supports quick switching between different friction rollers 5, covers complex wear scenarios of multi-substance contact, and the test results are closer to the actual usage requirements. The mechanical structure of the friction roller 5 with "insertion and locking" does not require tools, and the replacement process can be completed in a short time, significantly improving the test efficiency. Accurately control the contact force and rotational speed, and cooperate with the standardized glove clamping and friction roller 5 connection design to ensure the consistency and repeatability of test data.

[0037] Working principle: In the glove installation and preparation stage, the control panel 101 controls the moving table 202 to rise, raises the hand mold base 203 to a convenient operation position, and the operator puts the glove body 3 to be tested on the hand mold base 203, and the glove wrist is fixed through an elastic component. Subsequently, the moving table 202 descends, and with the aid of vision or sensors, the center of the glove rubber surface is accurately aligned with the center area of the surface of the friction roller 5 to ensure uniform contact during testing. For the adaptation link of the friction roller 5, the device adopts a quick-change connection component 6. When replacing the friction roller 5, it is inserted into the assembly window 404 of the fixed seat 4 after alignment. The mounting seat 602 slides along the guiding groove 609, and the inner wall of the guiding groove 609 presses against the inclined surface 608 of the limiting seat 607, causing the rotating roller 605 to compress the coil spring 606 and contract inward. When the mounting seat 602 slides to the limiting groove 610 at the end of the guiding groove 609, the elastic force of the coil spring 606 is released, pushing the limiting seat 607 into the limiting groove 610 to complete the locking connection between the friction roller 5 and the fixed seat 4. At the same time, the driving roller 403 is docked with the driving groove 501 to achieve power transmission. The disassembly process is the opposite. Pull the friction roller 5 outwards, and the limiting seat 607 compresses the coil spring 606 under the guidance of the inclined surface 608 of the limiting groove 610 and disengages from the limiting groove 610, thus quickly disassembling the friction roller 5. This design supports the replacement of friction rollers 5 with different textures and surface structures to simulate various wear conditions. During the test run phase, the target contact force and the rotation speed of the friction roller 5 are input through the control panel 101. The contact force is adjusted by controlling the descending amplitude of the moving table 202 or applying pressure, and the rotation speed is controlled by the driving module of the motor 401. After starting the motor 401, the driving roller 403 drives the friction roller 5 to rotate, and the moving table 202 maintains a constant contact force, enabling the rubber surface of the glove to continuously rub against the friction roller 5, and the generated debris falls into the waste box 102. During the test process, the sensors integrated in the control panel 101 continuously monitor parameters such as the contact force and rotation speed, and automatically adjust the position of the moving table 202 and the output of the motor 401 through a control algorithm according to the set values to form a closed-loop control. The operation interface can preset parameters, record data, and display curves, facilitating the operator to evaluate the test process and results. In addition, the device is equipped with a perfect safety protection mechanism. When the contact force exceeds the threshold value or the friction roller 5 jams, the control system automatically cuts off the power supply and stops the machine; the independent emergency stop button can quickly cut off the power supply in case of an emergency to ensure the safety of the operator. During daily maintenance, measures such as cleaning the guide rail 201, checking the coil spring 606 and the limiting seat 607 are taken to ensure the continuous and stable operation of the device. In summary, through the organic combination of each functional module, the device realizes the full-process automation and precise control from glove installation, friction roller 5 replacement to multi-condition testing, providing efficient and reliable technical support for the wear resistance evaluation of labor protection gloves.

[0038] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
