Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rubber performance detection, and in particular to a material detection test device for rubber preparation. BACKGROUND

[0002] Rubber preparation is an industrial activity that produces various rubber products by taking natural rubber, synthetic rubber or recyclable waste rubber as core raw materials and through processes such as mixing, vulcanization and molding. The products are widely used in fields such as daily consumption, medical health and industrial manufacturing. The performance stability of rubber products directly determines the use safety and efficiency of downstream application scenarios. Therefore, in the whole process of rubber preparation, detecting the key performance such as material strength and durability of rubber products is a core link for guaranteeing product quality and optimizing production processes.

[0003] A rubber material performance detection test device is disclosed in the prior art, which comprises a test base, a test sample clamping mechanism, a power drive assembly and a data acquisition module. The support frame is fixedly installed on the test base. The clamping mechanism is matched with the elastic pressing plate through the threaded pressing column to achieve firm fixation of the rubber test sample, and the clamping position can be adjusted according to the size of the test sample. The power drive assembly is matched with a speed reducer through a transmission shaft connected to the clamping mechanism. The folding performance detection device drives the clamping mechanism to make periodic reciprocating swing to simulate the bending stress scenario of the rubber product. The twisting performance detection device drives the clamping mechanism to rotate around the test sample axis to apply a torsional load to test the torsional performance. The data acquisition module integrates force sensors, angle sensors and temperature control components to record the load size, deformation angle and environmental parameters in real time during the detection process, and ensures the detection accuracy through a closed-loop control system.

[0004] However, the current performance detection of rubber products can only realize step-by-step operation of single-dimensional folding detection and single-dimensional twisting detection. Two performance tests need to be completed by different devices or different operating modes of the same device, which not only increases the operation steps of device switching and test sample re-clamping, but also leads to a complicated detection process and a large amount of time cost. In addition, the detection scenario is significantly different from the actual use conditions of the rubber product. In the real application environment, the rubber product often bears complex combined forces of folding and twisting. Single-dimensional step-by-step detection cannot truly simulate such complex stress state, which leads to the difficulty in accurately reflecting the performance of the product in actual use, and further affects the judgment of product quality and the optimization effect of production process.

[0019] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application discloses a testing apparatus for materials used in rubber preparation. (Refer to...) Figures 1-8 The device includes a base 1, a slide 3, a slide block 5, a drive component 2, a guide sleeve 4, a mounting rod 6, and an interface assembly 7. The slide 3 is mounted above the base 1. The slide block 5 is slidably connected to the slide 3. The drive component 2 is connected to the bottom of the slide block 5, providing driving force for the slide block 5 to move along the slide 3. The guide sleeve 4 is located on the side of the slide 3 away from the base 1, and a guide groove 401 is formed on the inner wall of the guide sleeve 4. The guide groove 401 includes a horizontal section and a spiral section, which are connected. The mounting rod 6 is connected to the slide block 5 along the length of the slide 3 and is located inside the guide sleeve 4. A guide block 601 is provided at one end of the mounting rod 6 near the horizontal section, and the guide block 601 is slidably connected in the guide groove 401. The other end of the mounting rod 6 extends out of the guide sleeve 4. The interface assembly 7 is located at one end of the guide sleeve 4 near the spiral section and is used to fix the material to be tested.

[0021] Specifically, base 1 provides a stable support foundation, slide groove 3 limits the sliding trajectory of slide 5 to prevent deviation, slide 5 provides a bearing and mounting carrier for mounting rod 6, and can drive mounting rod 6 to move synchronously; drive component 2 provides controllable driving force for slide 5 to slide, guide sleeve 4 provides mounting base for guide groove 401, the horizontal section of its inner wall guide groove 401 can guide guide block 601 to make linear movement, the spiral section can force guide block 601 to rotate around the axis of mounting rod 6 to realize the change of movement direction, interface component 7 is used to fix the rubber material to be tested and seal the port of the rubber material to be tested to prevent the material from falling off and shifting during the test; drive component 2 drives slide 5 to slide along slide groove 3, and mounting rod 6 moves synchronously in the horizontal section and spiral section of guide groove 401 through guide block 601, so that the material to be tested simultaneously bears the folding force in the linear direction and the torsional force in the rotational direction, realizing the synchronous integration of folding and torsional composite force detection, without the need for step operation or equipment switching.

[0022] During implementation, one end of the material to be tested is fixed to the interface component 7, and the other end is fixed to the end of the mounting rod 6 away from the guide block 601. After the drive component 2 is started, it drives the slide 5 to move along the slide groove 3. When the mounting rod 6 moves with the slide 5, the guide block 601 slides in the guide groove 401, and successively passes through the linear motion of the horizontal section and the rotational motion of the spiral section, thereby driving the mounting rod 6 and the material to be tested to simultaneously produce linear folding and rotational twisting, thus completing the composite performance test.

[0023] In an exemplary embodiment, see Figures 2-5 The bottom of the slide block 5 is provided with a slider 501, and the driving component 2 is connected to the slider 501. The driving component 2 includes a driving motor 201, a first driving rod 202, and a second driving rod 203. The driving motor 201 is located on the base 1, at the end near the slide groove 3 and away from the interface component 7. One end of the first driving rod 202 is fixedly connected to the driving motor 201. One end of the second driving rod 203 is rotatably connected to the end of the first driving rod 202 away from the driving motor 201, and the other end of the second driving rod 203 is rotatably connected to the slider 501.

[0024] Specifically, the slider 501 at the bottom of the slide block 5 makes the slide block 5 slide more smoothly and stably; the drive motor 201, as the power output source, can provide a stable and controllable driving force; the first drive rod 202 is fixedly connected to the drive motor 201 to realize power transmission; the two ends of the second drive rod 203 are rotatably connected to the first drive rod 202 and the slider 501 respectively, which can adapt to changes in motion angle and realize flexible power transmission. At the same time, it drives the slide block 5 to perform reciprocating linear motion, forming a compact crank-connecting rod type drive structure with stable power transmission. It can accurately control the movement speed and stroke of the slide block 5, ensuring the repeatability and accuracy of the detection process.

[0025] During implementation, after the drive motor 201 starts, it drives the first drive rod 202 to rotate around the motor output shaft. The first drive rod 202 drives the second drive rod 203 to move through a rotatable connection. The second drive rod 203 further pulls or pushes the slider 501, causing the slider 501 to drive the slide block 5 to make reciprocating linear motion along the slide groove 3, providing stable power for the compound motion of the mounting rod 6.

[0026] In an exemplary embodiment, see Figure 2 and Figure 7 The interface component 7 includes a fixed plug 701, a push rod 702, a connecting seat 703, and a limiting ball 7034. The fixed plug 701 includes a cover plate and a piston, which are coaxially arranged and have a through-hole 7011 at their center. The side of the cover plate facing away from the piston is connected to the port of the guide sleeve 4. Multiple push rods 702 are evenly spaced along the edge of the cover plate near the piston. The connecting seat 703 has a through-hole 7035 at its center. The plug is slidably connected in the receiving port 7035. The connecting seat 703 has a connecting groove 7031 on the side near the piston. The pushing end of the push rod 702 is connected in the connecting groove 7031. The connecting seat 703 has a limiting groove 7032 on the side away from the connecting groove 7031. The limiting groove 7032 has multiple spherical grooves 7033 spaced circumferentially on the side near the receiving port 7035. Multiple limiting balls 7034 are movably disposed in the spherical grooves 7033.

[0027] Specifically, the cover plate of the fixing plug 701 is used to connect with the port of the guide sleeve 4 to achieve fixed installation of the interface assembly 7. The piston is coaxial with the cover plate and can slide in the receiving port 7035 of the connecting seat 703. The clearance port 7011 provides clearance space for the mounting rod 6. The push rod 702 is evenly distributed along the edge of the cover plate, which can transmit the fixing force of the cover plate to the connecting seat 703 and limit the connecting seat 703 to prevent the connecting seat 703 from shifting. The receiving port 7035 of the connecting seat 703 realizes the connection between the fixing plug 701 and the connecting seat 703. 3. Sliding fit: The connecting groove 7031 fixes the pushing end of the push rod 702 to ensure a firm connection. The limiting groove 7032 is used to accommodate the end of the material to be tested. The spherical grooves 7033 are distributed circumferentially to adapt to materials of different thicknesses. The limiting ball 7034 is movably disposed in the spherical groove 7033, which can fit the material surface to enhance the fixing stability and fit, forming a multi-dimensional fixing structure. The material to be tested is firmly fixed and the surface is not easily damaged. At the same time, it can adapt to rubber materials of different sizes and shapes, improving the versatility of the device.

[0028] During implementation, the cover plate of the fixing plug 701 is fixed to the port of the guide sleeve 4, so that the piston slides into the receiving port 7035 of the connecting seat 703. The pushing end of the push rod 702 is embedded in the connecting groove 7031 of the connecting seat 703 to achieve limiting. Then, the end of the material to be tested is inserted into the limiting groove 7032 of the connecting seat 703. The limiting ball 7034 adheres to its surface under the extrusion of the material to form multi-point positioning. At the same time, the piston inserted into the receiving port 7035 can achieve sealing of the port of the material to be tested, thus completing the stable fixation of the material to be tested and facilitating further testing of the material.

[0029] In an exemplary embodiment, see Figure 1 An air pump 9 is provided on one side of the slide 3. The air inlet of the air pump 9 extends through the fixed plug 701 into the receiving port 7035.

[0030] Specifically, the air pump 9 works in conjunction with the interface component 7 to enable the device to perform stress testing on rubber composite materials under simulated air pressure, further closely reflecting the actual application conditions of products such as sealing rubber and rubber for pneumatic components, thereby improving the authenticity and reference value of the test results.

[0031] During implementation, after the material to be tested is fixed to the interface component 7, the air pump 9 is started. The air pump 9 inflates the accommodating port 7035 with air through the air inlet to the preset air pressure, applying air pressure load to the material to be tested. At the same time, the driving component 2 is started to drive the device to perform folding and torsion combined force detection, realizing multi-condition collaborative simulation detection.

[0032] In an exemplary embodiment, see Figure 2 There are two interface components 7, and the other one is detachably connected to one end of the mounting rod 6 that extends out of the guide sleeve 4. The two interface components 7 are used to fix the material to be tested.

[0033] Specifically, two interface components 7 are respectively located at the end of the guide sleeve 4 and the protruding end of the mounting rod 6, which can be fixed from both ends of the material to be tested. Compared with a single interface component 7, this can avoid the problems of one end being loose and uneven force during material testing. The other interface component 7 adopts a detachable connection method, which makes it easy to adjust the distance between the two interface components 7 according to the length of the material to be tested. It can adapt to rubber materials of different lengths and specifications, so as to achieve stable and adjustable fixation at both ends of the material to be tested. This ensures uniform force and consistent deformation during composite stress testing of the material, while expanding the device's adaptability range for materials of different sizes.

[0034] During implementation, one interface component 7 is fixed to one end of the guide sleeve 4 near the spiral section. According to the length of the material to be tested, another interface component 7 is installed at the corresponding position where the mounting rod 6 extends out of the guide sleeve 4. Then, the two ends of the material to be tested are inserted into the limiting grooves 7032 of the two interface components 7 respectively. The two ends are fixed by the limiting ball 7034, and the test is completed in conjunction with the movement of the mounting rod 6.

[0035] In an exemplary embodiment, see Figure 5 One end of the mounting rod 6 is a threaded section 602 for mounting interface assembly 7. The interface assembly 7 is fixed to the threaded section 602 of the mounting rod 6 by a nut.

[0036] Specifically, the threaded section 602 provides a detachable connection point for the interface assembly 7, which is simple in structure and reliable in connection; the nut cooperates with the threaded section 602, and the interface assembly 7 is firmly fixed to the mounting rod 6 by the thread locking force. The interface assembly 7 can be quickly disassembled by loosening the nut, which is convenient to operate.

[0037] During implementation, the fixing plug 701 of the interface component 7 is fitted onto the threaded section 602 of the mounting rod 6, so that the interface component 7 fits the preset position of the mounting rod 6. Then, the nut is screwed into the threaded section 602 and tightened. The locking and fixing are achieved by the nut fitting against the end face of the interface component 7. When the position needs to be adjusted or disassembled, the interface component 7 can be moved or removed by loosening the nut.

[0038] For example, between the two interface components 7, the mounting rod 6 is also provided with a plurality of inner support components 8 at even intervals.

[0039] Specifically, the internal support components 8 provide support from within the material under test, preventing excessive shrinkage, collapse, or localized stress concentration under combined folding and torsional stress. Multiple internal support components 8 are evenly spaced along the mounting rod 6, supporting different sections of the material and ensuring overall structural stability and uniform stress distribution. The internal support components 8, together with the interface components 7 at both ends, form a dual-protection structure of external fixation and internal support, effectively preventing deviations in test results caused by structural instability. This is particularly suitable for testing hollow rubber materials such as tubular and cylindrical shapes.

[0040] In an exemplary embodiment, see Figure 8The internal support assembly 8 includes a mounting component 801, a drive disc 805, a main gear 807, a micro motor 806, a mounting plate 8013, and an extension rod 802. The mounting component 801 includes a connecting ring 8011 and multiple adjusting grooves 8012. One side of each adjusting groove 8012 is open, and the multiple adjusting grooves 8012 are evenly spaced circumferentially along the connecting ring 8011. The connecting ring 8011 is fixedly connected to the mounting rod 6. The drive disc 805 has a through hole at its shaft center, and multiple drive grooves 8051 are evenly spaced axially on its surface. The drive disc 805 has teeth at its edge. The hole is coaxially arranged with the connecting ring 8011; the main gear 807 meshes with the teeth at the edge of the drive disk 805; the drive end of the micro motor 806 is coaxially connected with the main gear 807; the mounting plate 8013 is located on the outer periphery of the connecting ring 8011 and between any two adjacent adjustment slots 8012, and the micro motor 806 is mounted on the mounting plate 8013; the extension rod 802 is slidably connected in the adjustment slot 8012, and the side of the extension rod 802 near the drive disk 805 has a drive block 803 at one end of the connecting ring 8011 and an inner support bar 804 at the other end of the extension rod 802.

[0041] Specifically, the connecting ring 8011 of the mounting component 801 fixes the inner support assembly 8 to the mounting rod 6, ensuring that the inner support assembly 8 moves synchronously with the mounting rod 6. Multiple adjusting grooves 8012 are evenly distributed circumferentially along the connecting ring 8011, providing sliding guidance for the extension rod 802. The through hole of the drive disc 805 is coaxially set with the connecting ring 8011 to avoid interference with the connecting ring 8011 during rotation. The drive groove 8051 is used to drive the drive block 803 of the extension rod 802, and the teeth mesh with the main gear 807 to achieve power transmission. The main gear 807... 07 is coaxially connected to the drive end of the micro motor 806, transmitting the motor's rotational motion to the drive disk 805; the micro motor 806 provides precise power for the expansion and contraction of the inner support assembly 8; the mounting plate 8013 is fixed to the outer periphery of the connecting ring 8011, providing a stable mounting base for the micro motor 806; the extension rod 802 slides along the adjustment groove 8012, transmitting driving force to the inner support bar 804; the drive block 803 cooperates with the drive groove 8051 to realize the change of movement direction; the inner support bar 804 directly contacts the inner wall of the material to provide support force. The above features work together to form an adjustable inner support structure, through which the expansion range of the inner support bar 804 can be precisely controlled by the micro motor 806, adapting to hollow rubber materials with different inner diameter specifications, and the support force is uniform and controllable.

[0042] During implementation, the micro motor 806 is started, which drives the main gear 807 to rotate. The main gear 807 meshes with the drive disk 805, driving the drive disk 805 to rotate around the connecting ring 8011. The drive groove 8051 on the drive disk 805 slides with the drive block 803 of the extension rod 802, pushing the extension rod 802 to extend outward along the adjustment groove 8012, causing the inner support bar 804 to expand and fit against the inner wall of the material to form support. When it is necessary to retract the inner support bar 804, the micro motor 806 is started in reverse, the drive disk 805 rotates in the opposite direction, the extension rod 802 retracts along the adjustment groove 8012, and the inner support bar 804 disengages from the inner wall of the material.

[0043] In an exemplary embodiment, see Figure 8 The drive slot 8051 is arc-shaped, and the drive block 803 can move along the adjustment slot 8012 under the drive of the drive slot 8051.

[0044] Specifically, the arc-shaped drive groove 8051 enables the drive block 803 to obtain a smooth driving force during the rotation of the drive disk 805, avoiding movement jamming or impact. At the same time, it can precisely control the moving speed and stroke of the extension rod 802, ensuring that the expansion range of the inner support bar 804 is uniform.

[0045] When the drive disc 805 rotates during implementation, the inner wall of the arc-shaped drive groove 8051 slides in contact with the side of the drive block 803. Through the guiding effect of the arc surface, the drive block 803 drives the extension rod 802 to move smoothly along the adjustment groove 8012, so as to realize the uniform expansion or contraction of the inner support bar 804 and ensure the stability of the inner support bar 804 in the process of adhering to the inner wall of the material.

[0046] In an exemplary embodiment, see Figure 8 The inner support bar 804 is arc-shaped, and multiple inner support bars 804 form a ring when they are connected end to end.

[0047] Specifically, the arc-shaped inner support strip 804 can better fit the inner curved surface of the hollow rubber material, increase the contact area with the inner wall of the material, and avoid excessive local pressure that could damage the material; when multiple inner support strips 804 are connected end to end, they form a ring, which can provide full circumferential support to the inner wall of the material, ensuring that the material is subjected to uniform force in the circumferential direction and avoiding local deformation.

[0048] The operational process of this application will now be described in a common application scenario. It should be noted that this common implementation scheme should not be used as the basis for determining the essential features for understanding the technical problem claimed to be solved by this application; it is merely an example.

[0049] The implementation principle of the rubber preparation material testing device in this application embodiment is as follows: When using the rubber preparation material testing device, firstly, several inner support components 8 are evenly fixed on the mounting rod 6 through connecting rings 8011. Then, the micro motor 806 of the inner support component 8 is started, and the motor drives the main gear 807 to rotate. The main gear 807 meshes with the drive disk 805 to drive the drive disk 805 to rotate. The arc-shaped drive groove 8051 on the drive disk 805 pushes the extension rod 802 along the adjustment groove 8012 through the drive block 803. Extend outwards to allow the arc-shaped inner support bar 804 to expand synchronously. Then, fit the material onto the outside of the mounting rod 6 and the inner support assembly 8. Next, fit the interface assembly 7 onto the threaded section 602 of the guide sleeve 4 extending from the mounting rod 6. After adjusting the position according to the material length, tighten it with a nut. Then, insert both ends of the material to be tested into the limiting grooves 7032 of the connecting seats 703 of the two interface assemblies 7, respectively. The limiting balls 7034 in the spherical grooves 7033 inside the grooves adhere to the material surface under the material compression, forming a multi-point circumferential fixation. If it is necessary to simulate air pressure conditions, start the air pump. 9. The air pump 9 inflates the connecting seat 703 into the receiving port 7035 of the connecting seat 703 through the air inlet of the fixed plug 701 to the preset air pressure; then the drive motor 201 of the drive component 2 is started, the motor drives the first drive rod 202 to rotate, the first drive rod 202 drives the second drive rod 203 to move through the rotational connection, the second drive rod 203 pulls the slider 501 at the bottom of the slide block 5 to make reciprocating linear motion along the slide groove 3 above the base 1, the slide block 5 drives the mounting rod 6 to move synchronously, the mounting rod 6 extends into the guide block 601 at one end of the guide sleeve 4 first. Sliding within the horizontal section of guide groove 401, the mounting rod 6 drives the material to perform a linear folding motion. As the slide block 5 continues to move, the guide block 601 enters the spiral section of guide groove 401. The trajectory of the spiral section forces the guide block 601 to drive the mounting rod 6 to rotate around its own axis, ultimately causing the material to simultaneously bear linear folding force and rotational torsional force, completing the composite stress performance test. Throughout the process, the slide groove 3 ensures the accurate movement trajectory of the slide block 5, the inner support component 8 prevents the hollow material from collapsing, and the interface component 7 ensures that the material does not shift, achieving integrated composite testing.
