Description

Technical Field

[0001] This invention relates to the field of antibacterial bottle strength testing technology, specifically to a strength testing device and method for the production of regenerated antibacterial bottles. Background Technology

[0002] The column-type pressure sensor is a classic configuration of a resistance strain gauge force sensor based on a smart sensor. Its core is a columnar elastic body, which is widely used in heavy-duty and precision force measurement scenarios in industry. Its main body is made of high-strength alloy steel or stainless steel, with a compact and robust structure. Resistance strain gauges are attached to the middle of the column and form a Wheatstone bridge. During operation, axial pressure causes micron-level deformation of the elastic body, and the resistance of the strain gauge changes linearly accordingly. The bridge outputs a millivolt signal that is proportional to the pressure. After amplification and compensation, it is converted into a standard electrical signal for system acquisition. This sensor has an extremely wide range, an accuracy of ±0.05% to ±0.5%, strong resistance to off-center loads and overloads, and good long-term stability. It is the mainstream equipment in the field of industrial force measurement.

[0003] Recycled antibacterial bottles are mostly made by blending and modifying recycled plastics with antibacterial masterbatch. The materials themselves have inherent characteristics such as uneven molecular weight distribution, high impurity content, and large fluctuations in flowability and molding shrinkage. Compared with virgin raw material bottles, they have poor molding consistency, lower rigidity and dimensional regularity. In the production process of recycled antibacterial bottles, the vertical load tester is the core testing equipment for determining the axial compressive strength of the bottle and ensuring the safety of storage, transportation and stacking. It can accurately assess the structural stability of the recycled material and the antibacterial modified bottle body, providing a quantitative basis for production quality control. The instrument uses a column pressure sensor as the core measuring component. With its high precision and strong anti-interference ability, the column pressure sensor can collect the pressure change curve in real time throughout the process, accurately capture the critical load from yield deformation to rupture of the bottle body, effectively avoid the problem of unstable bottle strength caused by batch fluctuations of recycled materials and differences in antibacterial coatings, and ensure the consistency of finished product quality.

[0004] However, in actual production and testing, due to the characteristics of recycled raw materials and molding processes, recycled antibacterial bottles are prone to molding deviations such as uneven bottoms and inherent tilting. Most existing instruments lack a specific vertical alignment structure, making it difficult to quickly correct the bottle's center position. This leads to eccentricity and tilting after placement, causing the pressure axis to align with the bottle's axis, affecting the accuracy of the test. Furthermore, most of these testing instruments are not equipped with specialized clamping components suitable for the bottle, resulting in a lack of stable constraints during pressure testing. This instability can distort the data collected by the pressure sensor, failing to accurately reflect the bottle's actual pressure resistance. Consequently, this leads to large deviations and poor repeatability in test results, reducing testing efficiency and impacting the production process's assessment of product quality.

[0005] In view of the above problems, there is an urgent need for innovative design based on the original. Summary of the Invention

[0006] The purpose of the present invention is to provide a strength detection device and method for the production of regenerated antibacterial bottles, so as to solve the problem proposed in the above background technology that the bottom of the regenerated antibacterial bottle is uneven and it is easy to be eccentric and inclined after being placed. The technical solution of the present invention provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A strength detection device and method for the production of regenerated antibacterial bottles, including a detection table, a pressing seat is slidably arranged on the surface of the detection table, a pressing plate is installed at the bottom end of the pressing seat, a leveling component is arranged in the detection table, a limiting plate is arranged in the leveling component, a sliding column is slidably installed at the central position of the limiting plate, a floating seat is arranged at the end of the sliding column, a fixed seat is fixed on the surface of the floating seat, a clamping component is arranged on the surface of the fixed seat, and a locking seat is installed on the surface of the detection table;

[0008] The leveling component includes a plurality of elastic telescopic columns installed on the surface of the limiting plate and two limiting columns fixed on both sides of the limiting plate. A locking rod is fixed at the end of the sliding column, two locking connecting rods are symmetrically and rotatably installed at the end of the locking rod, a limiting block is rotatably connected to the end of the locking connecting rod, and it further includes a sliding rod that is elastically slidable in the locking seat and presses the sliding column through the sliding rod.

[0009] Preferably, the strength detection device further includes a columnar pressure sensor, and the columnar pressure sensor is arranged in the pressing seat.

[0010] Preferably, the top end of the elastic telescopic column abuts against the lower surface of the floating seat, limiting grooves are formed on both sides of the floating seat, and the ends of the limiting columns are located in the limiting grooves.

[0011] Preferably, the end of the sliding column is located inside the floating seat, and the limiting block is closely attached to the inner wall of the floating seat.

[0012] Preferably, the sliding rod is designed in a U shape, both ends of the sliding rod are designed to be inclined, and both ends of the sliding rod are respectively closely attached to the side wall of the pressing plate and the bottom end of the sliding column.

[0013] Preferably, the clamping assembly includes a fixed ring fixed to the surface of a fixed base, the surface of the fixed ring having multiple rotating grooves, a rotating ring rotatably mounted inside the fixed ring, a guide groove on the surface of the rotating ring, multiple rotating blocks rotatably mounted on the surface of the fixed base, a rotating column and a guide column fixed to the surface of each rotating block, the rotating column being slidably connected to the rotating groove, the guide column being slidably connected to the guide groove, a pressing block slidably mounted inside each rotating block, and a first oil tank fixed inside a pressure plate, the first oil tank containing a first piston column, and a second oil tank rotatably mounted on the surface of the fixed base, the end of the second oil tank being slidably mounted to a second piston column, the end of the second piston column being rotatably connected to the side wall of the rotating ring.

[0014] Preferably, the rotating column is located in the rotating groove, and the guide column is located in the guide groove.

[0015] Preferably, a buffer spring is provided inside the rotating block, and the rotating block is connected to the pressing block through the buffer spring.

[0016] Preferably, the first oil tank and the second oil tank are filled with oil, and the first oil tank and the second oil tank are connected by a hose.

[0017] Preferably, the method includes the following steps:

[0018] S1: Place the regenerated antibacterial bottle to be tested inside the fixed ring of the fixed seat. The floating seat rotates around the limiting block under gravity. With the help of the elastic telescopic column, the limiting column and the limiting groove, the verticality of the bottle is aligned.

[0019] S2: The lower pressure seat drives the pressure plate to descend, the sliding rod resets and raises the sliding column and locking rod, and the locking linkage squeezes the limit block to stick to the inner wall of the floating seat, locking the floating seat to prevent displacement;

[0020] S3: The pressure plate continues to move downwards, and the first piston rod is compressed, causing the oil to drive the second piston rod to push the rotating ring, which in turn drives the rotating block and the clamping block to clamp the bottle body. The buffer spring prevents the bottle body from being rigidly damaged.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention, through the design of a lower pressure seat, locking seat, pressure plate, floating seat, and leveling component, allows the floating seat, in conjunction with the leveling component, to rotate freely when placing the regenerated antibacterial bottle. This adapts to molding errors such as uneven bottle bottoms and inherent bottle body tilt, automatically correcting the bottle's verticality without manual calibration, improving positioning accuracy, and simplifying operation. After the pressure plate descends, it automatically locks the floating seat, structurally restricting its rotation and displacement. This prevents the bottle from shaking, tilting, or being subjected to eccentric force during testing, thus preventing positional deviation during detection. This ensures that the data collected by the pressure sensor is more accurate and reliable, improving the reliability of the pressure resistance test results.

[0023] 2. In this invention, through the setting of a pressure plate, a fixing seat, and a clamping assembly, during the testing operation, the pressure plate gradually descends with the mechanism to contact the regenerated antibacterial bottle. While the bottle body is subjected to pressure, it acts in the opposite direction on the first piston column, driving the clamping assembly to clamp and circumferentially limit the bottom side of the regenerated antibacterial bottle, preventing the bottle body from shaking or shifting during the subsequent pressure test, ensuring that the pressure axis is consistent with the center of the bottle body, and improving the stability and authenticity of the test data. At the same time, the clamping block is connected to a buffer spring to avoid non-detection damage or deformation of the bottle body due to excessive rigid clamping force, thus protecting the bottle body structure.

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] Please see Figures 1-10 This invention provides a technical solution: a strength testing device and method for the production of recycled antibacterial bottles, including a testing platform 1, a lower pressure seat 101 slidably disposed on the surface of the testing platform 1, a pressure plate 2 installed at the bottom end of the lower pressure seat 101, a leveling component disposed inside the testing platform 1, a limit plate 3 disposed inside the leveling component, a sliding column 4 slidably disposed at the center position of the limit plate 3, a floating seat 5 disposed at the end of the sliding column 4, which can adapt to the molding error of the bottle and quickly complete the verticality alignment, a fixed seat 6 fixed on the surface of the floating seat 5, a clamping component disposed on the surface of the fixed seat 6, the fixed seat 6 on the surface of the floating seat 5 cooperates with the clamping component to reliably limit the bottle and prevent shaking and displacement during testing, and a locking seat 102 is installed on the surface of the testing platform 1;

[0037] The leveling assembly includes multiple elastic telescopic columns 301 mounted on the surface of the limiting plate 3, and two limiting columns 302 fixed on both sides of the limiting plate 3. A locking rod 401 is fixed to the end of the sliding column 4. Two locking links 402 are symmetrically rotatably mounted on the end of the locking rod 401. The end of the locking link 402 is rotatably connected to a limiting block 403. The multiple elastic telescopic columns 301 on the limiting plate 3, together with the limiting columns 302 on both sides, can support the floating seat 5 to achieve multi-angle adaptive adjustment, to deal with uneven bottle bottoms and bottle body tilting problems, and to complete automatic alignment. It also includes a sliding rod 9 that is elastically slidable in the locking seat 102. By pressing the sliding column 4 with the sliding rod 9, the floating seat 5 can be quickly locked, so that the leveled position is fixed and displacement is avoided during detection.

[0038] As one embodiment of the present invention, the strength testing device also includes a column pressure sensor 103, which is installed in the lower pressure seat 101. It can directly and accurately collect the axial force value during the pressure application process, truly reflect the pressure resistance of the bottle, and provide accurate and true quantitative basis for the strength determination of the regenerated antibacterial bottle.

[0039] In one embodiment of the present invention, the top end of the elastic telescopic column 301 abuts against the lower surface of the floating seat 5, providing uniform and stable elastic support for the floating seat 5. Limiting grooves 501 are opened on both sides of the floating seat 5, and the end of the limiting column 302 is located in the limiting groove 501. This can both constrain the range of motion of the floating seat 5 and prevent excessive deviation during the leveling process, and not restrict the normal angle adjustment of the floating seat 5.

[0040] In one embodiment of the present invention, the end of the sliding column 4 is located inside the floating seat 5, and the limiting block 403 is close to the inner wall of the floating seat 5, which can uniformly fix the floating seat 5 from the inside during the locking stage, so as to prevent the floating seat 5 from shaking or shifting during the detection process.

[0041] In one embodiment of the present invention, the sliding rod 9 is designed in the shape of a U-shape, with both ends of the sliding rod 9 being inclined. The two ends of the sliding rod 9 are respectively close to the side wall of the pressure plate 2 and the bottom end of the sliding column 4. The sliding rod 9 is synchronously linked with the pressure plate 2 and the sliding column 4. When the pressure plate 2 descends, the upper end of the sliding rod 9 loses the pressure of the pressure plate 2 and resets, while the inclined surface at the lower end can smoothly push the sliding column 4 upward, thereby triggering the subsequent locking action. At the same time, the inclined surface at the upper end of the sliding rod 9 ensures that when the pressure plate 2 resets and re-presses the end of the sliding rod 9, it smoothly enters the interior of the locking seat 102.

[0042] In one embodiment of the present invention, the clamping assembly includes a fixed ring 601 fixed to the surface of a fixed base 6, a plurality of rotating grooves 602 formed on the surface of the fixed ring 601, a rotating ring 7 rotatably mounted inside the fixed ring 601, a guide groove 701 formed on the surface of the rotating ring 7, a plurality of rotating blocks 8 rotatably mounted on the surface of the fixed base 6, a rotating column 801 and a guide column 802 fixed on the surface of the rotating block 8, the rotating column 801 and the rotating groove 602 being slidably connected, the guide column 802 and the guide groove 701 being slidably connected, a pressing block 803 being slidably mounted inside the rotating block 8, and a first oil tank 201 fixed inside the pressure plate 2, a first piston column 202 being provided inside the first oil tank 201, and a second oil tank 203 rotatably mounted on the surface of the fixed base 6, a second piston column 204 being slidably mounted at the end of the second oil tank 203, the end of the second piston column 204 being rotatably connected to the side wall of the rotating ring 7, thereby realizing the synchronous linkage between the descent of the pressure plate 2 and the clamping action.

[0043] In one embodiment of the present invention, the rotating column 801 is located in the rotating groove 602 and the guide column 802 is located in the guide groove 701. The rotating groove 602 and the guide groove 701 limit the movement trajectory of the rotating block 8, ensuring that multiple rotating blocks 8 can move synchronously and that the regenerated antibacterial bottle is clamped evenly and reliably.

[0044] As one embodiment of the present invention, a buffer spring 804 is provided inside the rotating block 8. The rotating block 8 is connected to the pressing block 803 through the buffer spring 804, which can play a flexible buffering role when clamping the bottle, avoiding non-detectable squeezing deformation or damage to the regenerated antibacterial bottle caused by rigid clamping, while still ensuring sufficient clamping and limiting effect to prevent the bottle from shaking and deviating during detection.

[0045] In one embodiment of the present invention, the first oil tank 201 and the second oil tank 203 are filled with oil. The first oil tank 201 and the second oil tank 203 are connected by a hose. The oil smoothly transmits pressure to ensure uniform power transmission. At the same time, the second oil tank 203 is rotatably mounted on the surface of the fixed base 6 to flexibly adapt to the rotation trajectory of the rotating ring 7 and prevent motion interference. When the pressure plate 2 is pressed down, the first piston column 202 is compressed and squeezes the oil, which synchronously drives the second piston column 204 to extend and drive the rotating ring 7 to rotate.

[0046] As one embodiment of the present invention, the method includes the following steps:

[0047] S1: Place the regenerated antibacterial bottle to be tested into the fixing ring 601 of the fixed seat 6. The floating seat 5 rotates around the limiting block 403 under gravity. It adapts to the elastic telescopic column 301, the limiting column 302 and the limiting groove 501 to complete the verticality alignment of the bottle.

[0048] S2: The lower pressure seat 101 drives the pressure plate 2 to descend, the sliding rod 9 resets and lifts the sliding column 4 and the locking rod 401, and the locking link 402 squeezes the limiting block 403 to stick to the inner wall of the floating seat 5, locking the floating seat 5 to prevent it from shifting.

[0049] S3: The pressure plate 2 continues to move down, the first piston column 202 is pressed and the oil drives the second piston column 204 to push the rotating ring 7, which in turn drives the rotating block 8 and the clamping block 803 to clamp the bottle body. The buffer spring 804 prevents the bottle body from being rigidly damaged.

[0050] Working principle: When using this strength testing device for the production of recycled antibacterial bottles, the operator first places the recycled antibacterial bottle to be tested in the center position of the fixing ring 601 on the surface of the fixed seat 6. Under the action of gravity, the center of gravity of the bottle body shifts, causing the floating seat 5 to swing and deflect slightly around the limiting block 403. At the same time, it presses down on the elastic telescopic column 301, causing the telescopic column 301 to elastically expand and contract with the force. The elastic deformation of the telescopic column 301 adaptively compensates for the height difference at various points of the bottle bottom. During this process, the limiting column 302 is always constrained in the limiting groove 501, which radially and circumferentially limits the swing stroke and deflection angle of the floating seat 5 to avoid excessive swing and misalignment. The floating seat 5 automatically levels itself within a reasonable range, and finally the central axis of the bottle body is naturally corrected to a vertical state without the need for additional manual correction, thus improving the efficiency and accuracy of the initial positioning.

[0051] The detection device is then activated, driving the lower pressure seat 101 to descend smoothly. The lower pressure seat 101 drives the pressure plate 2 to move downward synchronously. The sliding rod 9, which was originally elastically slidably installed in the locking seat 102, loses the squeezing constraint of the side wall of the pressure plate 2 at its upper end, and then automatically resets and extends out of the side wall of the locking seat 102. The lower end of the sliding rod 9 is simultaneously displaced, and under the guidance of the inclined end, it is smoothly squeezed into the bottom end of the sliding column 4, lifting the sliding column 4 upward. The sliding column 4 drives the locking rod 401 to rise synchronously. Since the limiting block 403 is set inside the floating seat 5, and the two ends of the locking link 402 are respectively rotatably connected to the locking rod 401 and the limiting block 403, when the locking rod 401 rises, the locking link 402 squeezes the limiting block 403, making it close to the inner wall of the floating seat 5, fixing the angle and position of the floating seat 5, preventing the floating seat 5 from shifting position during subsequent detection, and avoiding eccentric force affecting the accuracy of the detection data.

[0052] As the pressure plate 2 continues to descend, the first piston rod 202, located on the lower surface of the pressure plate 2, first contacts the regenerated antibacterial bottle to be tested. The bottle body, under pressure, acts in the opposite direction on the first piston rod 202, pushing it to slide into the first oil tank 201. The first oil tank 201 is filled with oil. Under pressure, the oil enters the second oil tank 203 through a hose, pushing the second piston rod 204 outward. Simultaneously, because the second oil tank 203 is rotatably mounted on the surface of the fixed base 6, and the end of the second piston rod 204 is rotatably connected to the side wall of the rotating ring 7, the outward extension of the second piston rod 204 pushes the rotating ring 7 to rotate inside the fixed ring 601. The rotating column 801 and guide column 802 fixed on the side wall of the moving block 8 are located in the rotating groove 602 and guide groove 701 respectively. When the rotating ring 7 rotates, it pushes the rotating block 8 to rotate around the rotating groove 602 toward the center position, which drives the clamping block 803 to squeeze the regenerated antibacterial bottle and limit the regenerated antibacterial bottle. At the same time, the clamping block 803 is connected to the rotating block 8 through the buffer spring 804. While the clamping block 803 clamps and limits the regenerated antibacterial bottle, the buffer spring 804 can flexibly buffer the clamping force to avoid non-detectable damage or deformation of the bottle body due to excessive rigid clamping force, protect the original structure of the bottle body, and effectively protect the bottle body structure while stabilizing the limit.

[0053] After the first piston column 202 is squeezed and moved to the limited position, the lower pressure seat 101 drives the pressure plate 2 to continue to descend. The pressure on the bottle body acts on the pressure plate 2 and the lower pressure seat 101. The pressure causes the elastic body in the column pressure sensor 103 set inside the lower pressure seat 101 to produce micron-level deformation, accurately collecting the axial force value during the pressure application process, truly reflecting the pressure resistance of the bottle body, and providing accurate and true quantitative basis for the strength determination of the regenerated antibacterial bottle.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
