Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nitrile glove tensile test, in particular to a medical nitrile glove detection device. BACKGROUND

[0002] In many fields such as medical protection and industrial operation, nitrile gloves are widely used due to their excellent wear resistance, chemical resistance and good flexibility. The tensile performance is a key indicator for measuring the quality and durability of nitrile gloves, and accurate testing is crucial to ensure product safety. In the prior art, after the production of nitrile gloves is completed, the gloves are usually cut to obtain certain test samples, and then the samples are placed on a tensile testing machine for tensile testing.

[0003] However, this traditional testing method has obvious drawbacks. On the one hand, destructive cutting of nitrile gloves causes the cut samples to lose their functionality, resulting in resource waste. On the other hand, the existing tensile testing machine structure and testing principle have limitations, making it difficult to simultaneously test the tensile performance of multiple finger sleeves of a glove without damaging the overall structure of the glove. Not only is the testing efficiency low, but it also cannot fully and truly reflect the tensile performance of different finger sleeve parts of the whole glove. SUMMARY

[0004] Therefore, the purpose of the present application is to provide a medical nitrile glove detection device to solve the technical problems in the background art.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a medical nitrile glove detection device, comprising a main body, wherein the top of the main body is movably connected with a sleeving mechanism, and a profiling sleeving plate of the sleeving mechanism is used for sleeving the nitrile glove. Specifically, the fingertips of the five-finger part of the profiling sleeving plate and the profiling sleeving plate are slidably connected through an expansion plate. When the fingertips of the finger sleeve are stretched, the fingertips serve as a synchronous passive movement. The expansion plate slides in the same direction as the finger structure of the profiling sleeving plate. The end of the profiling sleeving plate is fixed with a turnover shaft, and the turnover shaft and the fingertips of the main body are rotatably connected through two groups of support frames. The turnover shaft and the support frame are connected through a damping rotation connection structure. The top of the main body is fixed with a finger sleeve root bottom end bearing mechanism, which comprises a plurality of bearing heads for bearing the finger sleeve root bottom end. The outer side of the sleeving mechanism is movably connected with a finger sleeve root top end pressing mechanism, which comprises a plurality of pressing heads for pressing the finger sleeve root top end. The finger sleeve root top end pressing mechanism and the finger sleeve root bottom end bearing mechanism cooperate to clamp and fix the finger sleeve root. Multiple sets of clamping heads are fixed inside the clamping plate, and the clamping plate is movably connected to the flipping shaft through two sets of flipping frames. Two sets of rotating power modules are installed on the top of the main body to provide flipping power to the flipping frames, so that after flipping, they work with multiple sets of bearing heads to clamp and fix the root of the finger sleeve. Multiple sets of the bearing heads are fixed to the top of the bearing plate, and the bearing plate and the main body are fixedly supported and connected by a fixing frame; The top of the main body slides with multiple sets of stretching mechanisms, and the stretching direction of the stretching mechanisms is consistent with the direction of the finger part of the contour sleeve plate. The stretching mechanism includes a fingertip base and a fingertip pressure plate for clamping and fixing the fingertip of the finger sleeve. The fingertip pressure plate flips under the action of the moving frame to press and fix the top of the fingertip of the finger sleeve. The top of the main body is fixed with multiple sets of guide mechanisms that cooperate with the stretching mechanism, and the stretching mechanism moves along the guide mechanisms to play a role in stretching detection of the finger sleeve. The fingertip pressure plate is rotatably connected to the fingertip base via a rotating shaft. Gears are fixed on the outer sides of both ends of the rotating shaft. A sliding tension seat is fixed at the bottom of the fingertip base. A movable frame is slidably connected to one side of the sliding tension seat. A rack that passes through the sliding tension seat and meshes with the gear is fixed at both ends of one side of the movable frame. The movable frame drives the rack to move and causes the rack to mesh with the gear to rotate. The rotating shaft drives the fingertip pressure plate to flip and close relative to the fingertip base. Each set of movable frames has a transmission rod fixed at both ends on the outside, and a transmission frame is connected to the outside of the transmission rod. The width of the through hole on the inside of the transmission frame is the same as the diameter of the transmission rod, and the length of the through hole is much larger than the diameter of the transmission rod, so as to play the role of adaptive passive adjustment of the transmission rod. A follower plate is fixed at the top end of the sliding stretching seat, and the follower plate is positioned corresponding to the position of the moving frame. It serves to move the sliding stretching seat through the follower plate. Magnetic blocks are fixed at corresponding positions on the inner sides of the follower plate and the moving frame, and the magnetic poles of the two sets of magnetic blocks are opposite, achieving the effect of opposite poles attracting each other. A pressure sensor is installed on the inner side of the bottom of the transmission frame, and a clamping force sensor is fixed on the top of the fingertip pressure plate. Its sensing head extends through the fingertip pressure plate to its inner side and is fixedly connected to a pad at the end. The guiding mechanism includes multiple sets of guide rails, and the orientation of the guide rails is consistent with the orientation of the finger part of the contour sleeve plate. The multiple sets of guide rails are used for the sliding guidance of the stretching mechanism. Through the collaborative design of the contouring fitting plate, the finger root clamping mechanism, and multiple sets of tensile mechanisms, non-destructive synchronous testing of the tensile performance of nitrile gloves is achieved. At the same time, the contouring fitting plate is used to simulate the natural stretching state of the glove, avoiding cutting that would damage the integrity of the glove and reducing resource waste. The rotating power module drives the clamping head and the bearing head to clamp the finger root, and the fingertip clamping plate with gear and rack transmission clamps the fingertip, ensuring that the finger of the glove is fixed and stable during the tensile test. A drive mechanism is installed at the top of the main body, and a power plate is fixed to the cylinder output end of the drive mechanism. Multiple mounting plates connected to multiple pressure sensors are fixed on the top of the power plate. A control box is set at the bottom of the main body, and the control box plays the role of device control.

[0006] By adopting the above technical solution, the cylinder drives the tensioning mechanism to move along the guide rail, and simultaneously performs tensile testing on the five finger sleeves. The pressure sensor and clamping force sensor collect data in real time, and the control box automatically compensates for the damping force and the sliding friction of the telescopic plate, accurately obtaining the tensile strength data of each group of finger sleeves. This device can test multiple groups of finger sleeves at the same time, and the testing efficiency is 5 times higher than that of the traditional method. Moreover, the gloves are not damaged after testing, and it can comprehensively and truly reflect the tensile performance of different parts of the entire glove. It is suitable for quality testing and R&D testing of medical nitrile gloves.

[0007] Furthermore, a stop block corresponding to the rack is fixed on one side of the fingertip base.

[0008] By adopting the above technical solution, the stop block plays a blocking role after the rack is reset.

[0009] In summary, the present invention has the following advantages: Through the collaborative design of a contoured fitting plate, a finger cot root clamping mechanism, and multiple sets of stretching mechanisms, the present invention achieves non-destructive synchronous testing of the tensile performance of nitrile gloves. Simultaneously, the contoured fitting plate simulates the natural, relaxed state of the glove, avoiding damage to the glove's integrity during cutting and reducing resource waste. A rotating power module drives the clamping head and bearing head to clamp the finger cot root, while a gear-rack driven fingertip clamping plate clamps the fingertips, ensuring stable finger cot fixation during tensile testing. A cylinder drives the stretching mechanism to move along a guide rail, simultaneously performing tensile testing on all five finger cots. Pressure sensors and clamping force sensors collect data in real time, and the control box automatically compensates for damping forces and sliding friction of the telescopic plate, accurately obtaining tensile strength data for each set of finger cots. This device can test multiple sets of finger cots simultaneously, increasing testing efficiency by 5 times compared to traditional methods, and leaves the glove undamaged after testing. It comprehensively and accurately reflects the tensile performance of different parts of the entire glove, making it suitable for quality testing and R&D testing of medical nitrile gloves.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0013] The embodiments of the present invention will now be described.

[0014] Example like Figures 1-9 As shown, the testing device provided in this embodiment mainly consists of a main body 1, a sleeve mechanism 2, a finger cot root top pressing mechanism 3, a finger cot root bottom bearing mechanism 4, a guide mechanism 5, a tensioning mechanism 6, a drive mechanism 7, and a control box 8. It achieves non-destructive testing of glove tensile performance through contour sleeve and multi-finger synchronous tensioning. The main body 1 adopts a metal frame structure, with a sleeve mechanism 2, a finger sleeve root top pressing mechanism 3, a finger sleeve root bottom bearing mechanism 4 and a guide mechanism 5 installed at the top, and a control box 8 fixed at the bottom, containing a built-in circuit board and data processing module; The control box 8 integrates a PLC controller, power module and data interface, and communicates with an external display screen via a connection cable to display tensile test data in real time. Two sets of support frames 201 of the sleeve mechanism 2 are fixed to the top of the main body 1, supporting the flip shaft 202. The flip shaft 202 is connected to the support frame 201 with damping rotation, and the end is fixed with the contour sleeve plate 203. The contouring fitting plate 203 is a five-finger shaped plastic plate, and the fingertips 204 are slidably connected to the main body through the telescopic plate 205 to simulate the natural extended state of the glove. The flipping frame 301 is connected to the clamping plate 302, and the bottom is provided with a clamping head 303. The flipping is driven by a rotary power module 304, such as a stepper motor. The bearing plate 401 is fixed to the main body 1 by the fixing bracket 403, and the top is provided with a bearing head 402, which cooperates with the pressing head 303 to clamp the root of the finger sleeve. The bottom of the sliding stretching seat 601 is slidably connected to the guide rail 501, and the top is fixed with the fingertip base 602; The fingertip pressure plate 603 is rotatably connected to the fingertip base 602 via a rotating shaft 604. The gears 605 on both sides mesh with the rack 607 and are driven by the movable frame 606 to flip and clamp the fingertip. After the follower plate 611 is attached to the moving frame 606, it is attracted by the magnetic block 612. The transmission rod 608 and the transmission frame 609 cooperate to adapt to different stretching directions. Multiple sets of guide rails 501 are fixed on the main body 1, and the guiding direction is consistent with the finger direction of the contouring sleeve plate 203 to ensure accurate stretching direction; The output end of the cylinder 701 of the drive mechanism 7 is connected to the power plate 702, and the top mounting plate 703 is connected to the pressure sensor 610, which drives the tensioning mechanism 6 to move. The clamping force sensor 613 is fixed to the fingertip pressure plate 603 to detect the fingertip clamping force; The pressure sensor 610 is installed on the transmission frame 609 to collect tensile force data in real time during the stretching process; Glove application and securing Preparation: Start the control box 8, initialize the system parameters, set the stretching speed, such as 50mm / min and the maximum stretching displacement, such as 200mm, manually flip the sleeve mechanism 2 and the finger sleeve root top pressing mechanism 3, and open the operating space. Glove fitting: Put the nitrile gloves on the outside of the contour fitting plate 203, ensuring that the five fingers are fully extended, and the base of the finger gloves is aligned with the position of the bearing head 402 after flipping. Root clamping: Start the rotation power module 304 to drive the finger sleeve root top clamping mechanism 3 to flip, and the clamping head 303 and the bearing head 402 cooperate to clamp the root of the finger sleeve; Tensile testing operation Fingertip clamping: Cylinder 701 slowly extends, driving pressure sensor 610 and transmission frame 609 to move. Moving frame 606 drives gear 605 to rotate through rack 607. Fingertip pressure plate 603 flips to press the fingertip. When moving frame 606 is in contact with follower plate 611, clamping force sensor 613 detects that the pressure just reaches the set clamping pressure. As moving frame 606 drives sliding tension seat 601 to continue moving, under the action of rack 607 and gear 605, the fingertip pressure plate 603 always maintains a constant pressure state. Synchronous stretching: Cylinder 701 continues to extend, and the moving frame 606 drives the sliding stretching seat 601 to move along the guide rail 501 through the follower plate 611. The fingertip 204 passively slides with the telescopic plate 205, and the pressure sensor 610 records the tension-displacement curve of each group of finger sleeves in real time. Data acquisition: When the tensile displacement reaches the set value or the tensile force exceeds the rated value, the cylinder 701 stops automatically, the control box 8 records the peak tensile force and the fracture displacement, and simultaneously subtracts the damping force of the fingertips of the sliding tension seat 601 and the guide rail 501 and the sliding friction force of the fingertips of the telescopic plate 205 and the contour sleeve plate 203, and finally generates a test report. Reset after detection The cylinder 701 slowly retracts, first driving the sliding tension seat 601 to reset via the magnetic block 612. The continued retraction and reset of the cylinder 701 then separates the magnetic block 612, causing the fingertip pressure plate 603 to open. Then, the pressing mechanism 3 at the base of the finger sleeve is flipped over, the glove is removed, and the test is completed.

[0015] The working principle of this invention is as follows: When in use, the device is powered and controlled by the control box 8 connected to the bottom of the main body 1. At the same time, it can be electrically connected to an external display screen through the connection port on the back, so that the tensile data after the test can be displayed and recorded. When in use, the staff manually flips the sleeve mechanism 2 and the finger glove root top pressing mechanism 3 open to a certain angle, and makes the finger glove root top pressing mechanism 3 rotate along the flipping axis 202 to a certain angle, so that it is separated from the sleeve mechanism 2 by a certain distance, which facilitates the staff to put on the nitrile gloves to be tested. During the fitting process, the staff manually slipped the nitrile glove to be tested onto the outside of the conformal fitting plate 203. The structure of each finger part of the conformal fitting plate 203 is designed to be the stretched state of the nitrile glove itself, so that each finger part of the nitrile glove can be kept in a straight position after fitting, which facilitates the subsequent tensile testing of each finger part. After the nitrile gloves to be tested are put on, the staff manually rotates the putting mechanism 2 along the flipping shaft 202 at a certain angle so that the putting mechanism 2 is rotated to a horizontal state. At this time, the root of the finger cot of the nitrile glove is located at the top of the bearing mechanism 4 at the bottom of the root of the finger cot of the corresponding finger, while the fingertip of the nitrile glove is located on the fingertip base 602 of the stretching mechanism 6. Then, the rotation power module 304 is activated. Under its power, the pressing mechanism 3 at the top of the finger sleeve root is rotated at a certain angle, so that its multiple pressing heads 303 are pressed at the position of the finger sleeve root. Together with the bearing head 402 of the bearing mechanism 4 at the bottom of each finger sleeve root, they form a clamping and fixing effect on the root of each finger sleeve. This avoids the connection between the finger sleeve root and the glove palm when the stretching mechanism 6 stretches the finger tip of the finger sleeve, which affects the stretching test. Furthermore, both the pressing head 303 and the bearing head 402 have rubber sheets with anti-slip textures fixed on their inner sides, which ensures a stable clamping force on the root of the finger sleeve and prevents loosening and slippage. At the same time, since the finger part of the contoured sleeve plate 203 is located inside the nitrile glove, the finger root structure of the contoured sleeve plate 203 will provide support on the inner side of the root of the finger sleeve. After the pressing head 303 applies force, the clamping and fixing effect of the root of the finger sleeve is further improved. Once the nitrile glove to be tested is fixed at the base, the cylinder 701 of the drive mechanism 7 extends. When the cylinder 701 extends, it drives the five sets of mounting plates 703 to move as a whole through the power plate 702. Each set of mounting plates 703 is connected to a pressure sensor 610 on one side, and the pressure sensor 610 is connected to the corresponding tension mechanism 6 on one side. Thus, with the cooperation of the tension mechanism 6 and the pressure sensor 610, the tensile strength of each finger of the nitrile glove can be tested simultaneously. Specifically, when cylinder 701 extends, it first drives transmission frame 609 to move via pressure sensor 610. Then, transmission frame 609 drives moving frame 606 via two sets of transmission rods 608. At this time, moving frame 606 first moves relative to sliding tension seat 601. When the moving frame 606 moves, it drives the two sets of racks 607 to mesh with the gears 605 to rotate. The rotation of the gears 605 then drives the fingertip pressure plate 603 to flip and close relative to the fingertip base 602 through the rotating shaft 604. At this time, the fingertip pressure plate 603, which is closed relative to the fingertip base 602, presses down and clamps the fingertip part of the finger sleeve. At the same time, the clamping force generated by the fingertip pressure plate 603 makes the fingertip part of the finger sleeve and the outer side of the fingertip 204 press and stick together. As the moving frame 606 continues to move until it is in contact with the follower plate 611, the two sets of magnets 612 attract each other with opposite polarities. At this point, that is, the clamping force of the fingertip pressure plate 603 on the fingertip of the finger sleeve reaches the set value, which can maintain a stable clamping force without damaging the glove and avoid detachment during the stretching process. Under the detection of the clamping force sensor 613, the signal of stable clamping of the fingertip is transmitted to the controller, and then the controller transmits the signal to the corresponding pressure sensor 610 to perform a zeroing operation. Then, cylinder 701 continues to extend, and the moving frame 606 moves, driving the sliding tension seat 601 and fingertip base 602 to slide along the corresponding guide rail 501 via follower plate 611. As cylinder 701 gradually extends, each group of finger parts of the nitrile glove to be tested is simultaneously stretched and tested. This achieves the goal of simultaneously stretching and testing multiple groups of finger parts of the nitrile glove without damaging it, resulting in good overall testing performance. When the transmission frame 609 drives the transmission rod 608 to move, the direction of movement of the tensioning mechanism 6 and the direction of extension of the cylinder 701 are inconsistent. As a result, the transmission rod 608 passively slides laterally inside the transmission frame 609 to ensure the tensioning force without affecting the movement of the tensioning mechanism 6 along the guide mechanism 5 in different directions. Furthermore, when the fingertip base 602 and the fingertip pressure plate 603 clamp the fingertip part of the finger sleeve for stretching, each group of fingertips 204 slides relative to the contouring sleeve plate 203 through the telescopic plate 205. In other words, the contouring sleeve plate 203 will not affect the stretching test operation of each group of finger sleeves of the nitrile glove. Furthermore, the extension direction of each group of guide rails 501 is consistent with the orientation of each group of finger structures of the contour sleeve plate 203, thereby enabling each group of finger sleeves to perform tensile testing along its natural direction, thus improving the overall tensile testing accuracy. The sliding tension seat 601 and the corresponding guide rail 501 are connected by damping sliding. When the moving frame 606 initially moves and causes the fingertip pressure plate 603 to flip, the sliding tension seat 601 will not move along the guide rail 501, thus not affecting the clamping effect of the fingertip. Finally, after the tensile test is completed, the controller and circuit board and other electrical components in the control box 8 make the data generated by the pressure sensor 610 subtract the sliding damping force of the fingertip of the sliding tension seat 601 and the guide rail 501, and also subtract the sliding friction force generated when the telescopic plate 205 extends relative to the conformal sleeve plate 203, so as to obtain the tensile strength data of each set of finger sleeves. The overall use effect is good. After the tensile test structure is completed, the cylinder 701 retracts and returns to its original position. During the retraction process, the moving frame 606 and the follower plate 611 are attracted by opposite magnetic blocks 612. The magnetic force is greater than the damping force between the sliding tension seat 601 and the guide rail 501. In other words, during the retraction operation, the fingertip pressure plate 603 is still clamping and fixing the fingertip of the finger sleeve. After the sliding tension seat 601 returns to its initial state, the cylinder 701 continues to retract, causing the two sets of magnetic blocks 612 to separate from each other. This allows the moving frame 606 to slide relative to the sliding tension seat 601, and the fingertip pressure plate 603 to open relative to the fingertip base 602. This prevents the nitrile glove from rebounding rapidly after stretching, ensuring the safety of the operator.
