Description

Technical Field

[0001] This invention relates to the technical field of viscosity testing, and more particularly to a resin viscosity testing device and a manufacturing process for a breather winding composite gas cylinder. Background Technology

[0002] In the winding process, the resin needs to impregnate the fiber and be evenly coated. The resin viscosity directly affects the impregnation effect.

[0003] Stable viscosity ensures the mechanical properties of the resin after curing during winding molding, which is a key process guarantee for the core properties of gas cylinders such as pressure resistance and fatigue resistance. Therefore, resin viscosity testing is a key link in material research and development, production and application, ensuring the adaptability and reliability of the resin in various application scenarios.

[0004] However, in existing technologies, due to varying resin testing accuracy requirements in different application scenarios, it is necessary to change the rotor to achieve accurate measurement of resins with different viscosity grades and flow characteristics, ensuring data reliability and applicability. Therefore, to adapt to resin samples with different viscosity ranges, the corresponding rotor needs to be changed during testing. The rotor and rotor connector of the viscometer are themselves relatively small in size. As the core component that directly contacts the resin being tested, the threaded structure on the top of the rotor for connection is delicate and fragile. The threaded hole of the rotor connector is also small. In actual installation, the operator must first use one hand to hold and fix the rotor connector to prevent the connector from rotating during installation. However, due to the small size of the connector, the palm and fingers inevitably completely cover the connector surface, causing the threaded hole on the rotor connector to be completely obscured. The operator cannot visually observe the specific position and angle of the threaded hole. This complete visual obstruction makes the installation process lack the most basic intuitive reference. The operator can only rely on past experience to operate, first aligning the thread on the top of the rotor with the threaded hole of the rotor connector. For experienced operators... While it's true that even without visual reference, one can roughly judge the alignment direction through long-term practice, those lacking sufficient operational experience often struggle to accurately and quickly grasp the relative position of the rotor and connector. Repeated attempts are frequently necessary to find the approximate alignment, significantly extending installation time. Furthermore, when attempting threaded connections, the lack of visual inspection of the thread engagement means that if the rotor's top thread and the connector's threaded hole are not accurately aligned, thread misalignment is highly likely during rotor rotation. Continued forceful rotation at this point can damage the threaded structure of both the rotor and connector, leading to issues like stripped threads and chipped teeth. Uneven stress can also cause the rotor to bend and deform, potentially damaging the rotor connector. This results in significant instability in installation quality. Even experienced operators may experience installation deviations due to fatigue or lack of concentration, leading to frequent instances of loose threaded connections. During subsequent viscosity testing, the rotor may loosen or even fall off due to vibration, affecting the accuracy of test data. A fallen rotor could also damage other equipment components or the sample container, causing losses. Summary of the Invention

[0005] The purpose of this invention is to provide a resin viscosity testing device and a manufacturing process for a breather winding composite gas cylinder, solving the problem of inconvenience in changing different models of rotors.

[0006] This invention proposes a resin viscosity testing device, comprising a lifting frame, a drive tester disposed outside the lifting frame, a rotor disposed below the drive tester, a shaft disk fixedly connected to the output end of the drive tester, two clamping members rotatably connected to the shaft disk, a support rod fixedly connected to the bottom of the shaft disk, a locking member slidably connected to the support rod, a locking rod disposed inside the support rod, a reinforcing member disposed on one side of the support rod, a connecting rod rotatably connected at one end to the clamping member, a push bar rotatably connected to the other end of the connecting rod, and two protective plates fixedly connected below the shaft disk. The top end of the rotor is located between the clamping member and the support rod. The two clamping members are symmetrical about the central axis of the shaft disk. The number and position of the push bar, connecting rod, and clamping member correspond one-to-one. The push bar is slidably connected to the shaft disk. The locking member is used to fix the clamping member. By the rotor pressing the locking member, the bottom end of the clamping member is joined with the bottom end of the support rod to reinforce the top end of the rotor. The locking rod locks the bottom end of the clamping member.

[0007] Furthermore, the drive tester is provided with a control wheel on its exterior, two guide grooves are provided on the shaft disk, and two protrusions are provided on the bottom of the shaft disk. The two guide grooves and protrusions are symmetrical about the central axis of the shaft disk, and the connection point between the connecting rod and the push bar is located inside the guide groove.

[0008] Furthermore, the clamping member includes a pressure bar disposed at the bottom of the shaft plate, a round shaft fixedly connected to the pressure bar, and a torsion spring connected between the pressure bar and the protrusion. The round shaft is rotatably connected inside the protrusion. A round groove is provided at the bottom end of the pressure bar. A through groove is provided on the pressure bar. The rotation angle of the torsion spring is greater than 90 degrees. An arc plate is provided on one side of the pressure bar.

[0009] Furthermore, a shaft is provided at the bottom of the support rod, and an inner groove and a square groove are provided on the support rod. The square groove is located above the shaft, and the diameter of the circular groove is equal to the outer diameter of the shaft.

[0010] Furthermore, the locking component includes a crossbar disposed on one side of the support rod, a square rod fixedly connected to the crossbar, two shafts respectively located at one end of the crossbar, a sleeve fixedly connected to the square rod, and a return spring connected between the support rod and the crossbar.

[0011] Furthermore, the sleeve rod is located on the other side of the support rod, and the square rod passes through the square groove and is fixedly connected to the sleeve rod. The sleeve rod and the inner groove have the same shape and size. The bottom end of the sleeve rod is located outside the shaft. The diameter of the shaft rod is the same as the diameter of the through groove.

[0012] Furthermore, the locking rod includes a push rod slidably connected inside the shaft strip, and a return spring is connected between the push rod and the shaft strip. The push rod has a vertical slot at one end near the reinforcing member, and an arc groove at the other end. When the return spring is not deformed, the width of the arc groove is less than the distance between the arc plate and the pressure bar.

[0013] Furthermore, the connecting rod does not contact the torsion spring and the shaft, and one end of the connecting rod is rotatably connected to the outside of the ferrule.

[0014] Furthermore, the reinforcement includes a thin rod slidably connected to one side of the support rod, a weak spring connecting the thin rod and the guard plate, and the bottom end of the thin rod and the end of the push rod with the vertical slot are both set to be arc-shaped.

[0015] This invention provides, in one aspect and in another, a manufacturing process for a respirator-wound composite gas cylinder, employing a resin viscosity testing device, comprising the following steps:

[0016] Step 1: Test the resin viscosity using a drive tester and rotor to ensure the resin's adhesion, while also ensuring that the carbon fiber quality and winding parameters meet the requirements.

[0017] Step 2: Impregnate the carbon fibers with the prepared resin system containing carbon nanotubes to allow the resin to fully penetrate the carbon fibers.

[0018] Step 3: Wrap the impregnated carbon fiber to form the blank of the composite gas cylinder.

[0019] Step 4: Curing treatment is performed on the composite gas cylinder blank to ensure that the resin is fully cured, resulting in the final wound composite gas cylinder.

[0020] The beneficial effects of this invention are:

[0021] The rotor is mechanically clamped and positioned using clamping components and support rods. Operators only need to push the rotor directly by hand to fix it, avoiding visual obstruction. The mechanical structure makes the relative positional relationship between the rotor and components clear during installation. Whether experienced or inexperienced, the installation can be completed automatically by simply pushing the rotor, reducing the difficulty of operation and shortening the installation time.

[0022] The clamping components are double-locked by locking rods and reinforcements, ensuring a firm connection of the rotor during testing. This effectively prevents the rotor from loosening or even falling off, guaranteeing the safety of the testing process. At the same time, the stable rotor connection ensures the stability of the testing process, thereby guaranteeing the accuracy of the test data. This provides a reliable process guarantee for resin viscosity testing, and the rotor can be quickly changed to adapt to the testing needs of resins with different viscosity ranges.

[0023] The rotor squeezes the sleeve rod to unlock the locking mechanism. The pressure bar automatically engages with the torsion spring, and the push rod pushes to complete the secondary locking. Structurally, it relies on the torsion spring and return spring to provide power. During locking, the pressure bar's circular groove and the shaft bar assemble to achieve the first-level locking. The push rod's circular groove squeezes the arc plate and the thin rod locks the push rod to complete the second-level locking. The double mechanical locking ensures rotor stability and safety. Moreover, the standardized components such as springs and shafts have low procurement and replacement costs, are easy to maintain, and have strong environmental adaptability.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Example 1, refer to 1- Figure 9 This invention provides a resin viscosity testing device, comprising a lifting frame 1, a drive tester 2 disposed outside the lifting frame 1, a rotor 3 disposed below the drive tester 2, a shaft disk 4 fixedly connected to the output end of the drive tester 2, two clamping members 5 rotatably connected to the shaft disk 4, a support rod 6 fixedly connected to the bottom of the shaft disk 4, a locking member 7 slidably connected to the support rod 6, a locking rod 8 disposed inside the support rod 6, a reinforcing member 9 disposed on one side of the support rod 6, and a connecting rod 10 rotatably connected at one end to the clamping member 5. The other end of the connecting rod 10 is rotatably connected to the push bar 11, and there are two guard plates 12 that are fixedly connected below the shaft disk 4. The top of the rotor 3 is located between the clamping member 5 and the support rod 6. The two clamping members 5 are symmetrical about the central axis of the shaft disk 4. The number and position of the push bar 11, the connecting rod 10 and the clamping member 5 correspond one-to-one. The push bar 11 is slidably connected to the shaft disk 4. The locking member 7 is used to fix the clamping member 5. By the rotor 3 pressing the locking member 7, the bottom end of the clamping member 5 is joined with the bottom end of the support rod 6 to reinforce the top of the rotor 3. The locking rod 8 is used to lock the bottom end of the clamping member 5.

[0037] Specifically, a clamping structure is formed by the clamping member 5 and the support rod 6. The width of the top of the rotor 3 is equal to the distance between the clamping member 5 and the support rod 6. A transmission link is formed by the locking member 7. The operator installs the top of the rotor 3 on the support rod 6, thereby using the rotor 3 to push the locking member 7 to release the locking member 5. At this time, the top of the rotor 3 has been placed between the clamping member 5 and the support rod 6, thus achieving initial positioning through the clamping member 5. At the same time, the locking rod 8 presses the clamping member 5 to form a secondary lock. That is, the primary lock is formed by the connection between the support rod 6 and the clamping member 5. When the clamping member 5 is in place, the secondary locking is completed by the locking rod 8 inside the support rod 6. After the clamping member 5 and the support rod 6 are assembled, the locking rod 8 is pushed to form a double locking of radial fixation and axial limitation. That is, the top of the rotor 3 is placed between the clamping member 5 and the support rod 6, so that the clamping member 5 and the support rod 6 can be assembled. When replacing the rotor 3, it is only necessary to push the push bar 11 to separate the clamping member 5 and reset the clamping member 5. When the drive tester 2 is not started, the shaft disk 4 can be rotated at will to adjust the position, which is convenient for the placement of the rotor 3.

[0038] Reference Figures 1-5The drive tester 2 is equipped with a control wheel 21 on its exterior. By controlling the control wheel 21, the height of the drive tester 2 can be controlled, thereby adjusting the height of the rotor 3. Two guide grooves 401 are opened on the shaft disk 4, and two protrusions 41 are provided on the bottom of the shaft disk 4. The two guide grooves 401 and the protrusions 41 are symmetrical about the central axis of the shaft disk 4. The connection point between the connecting rod 10 and the push bar 11 is located inside the guide groove 401.

[0039] Specifically, a control wheel 21 is specially provided on the outside of the drive tester 2. By rotating the control wheel 21, the operator can precisely control the drive tester 2 to move up and down along the lifting frame 1, thereby driving the shaft disk 4, clamping parts 5 and other components connected below it to rise and fall synchronously, ultimately realizing the flexible adjustment of the rotor 3 height. This ensures that the rotor 3 can be accurately immersed to the appropriate depth according to the amount of resin sample to be tested and the testing requirements. In addition, the guide groove 401 restricts the movement path of the connection point between the connecting rod 10 and the push bar 11. When the push bar 11 slides on the shaft disk 4, the connection point between the connecting rod 10 and the push bar 11 moves along the inside of the guide groove 401, effectively restricting the movement trajectory of the push bar 11 and the connecting rod 10, ensuring the stability and accuracy of the transmission process, and preventing the components from shifting or jamming during movement. At the same time, the protrusion 41 supports the clamping parts 5.

[0040] When the clamping member 5 rotates, it pulls the connecting rod 10, which in turn pulls the push bar 11 to move horizontally. This pushes the push bar 11 back, which in turn pulls the connecting rod 10. The connecting rod 10 then pulls the clamping member 5, thus resetting the clamping member 5.

[0041] Reference Figures 1-7 The clamping member 5 includes a pressure bar 51 set at the bottom of the shaft plate 4, a round shaft 52 fixedly connected to the pressure bar 51, and a torsion spring 53 connected between the pressure bar 51 and the protrusion 41. The round shaft 52 is rotatably connected to the inside of the protrusion 41. A round groove 501 is opened at the bottom end of the pressure bar 51, and a through groove 502 is opened on the pressure bar 51. The rotational force of the torsion spring 53 is used to rotate the pressure bar 51, so that the two pressure bars 51 finally fit together. The rotation angle of the torsion spring 53 is greater than 90 degrees, which strengthens the fitting force of the two pressure bars 51, thereby ensuring the stability of the rotor 3. When the pressure bar 51 is not blocked by the locking member 7, an arc plate 512 is provided on one side of the pressure bar 51.

[0042] Specifically, the locking piece 7 is inserted into the through slot 502 to fix the pressure strip 51. The round shaft 52 is fixedly connected to the pressure strip 51 and rotatably connected inside the protrusion 41, so that the pressure strip 51 can rotate around the round shaft 52 as the axis, providing rotational support for the opening and closing action of the pressure strip 51. The torsion spring 53 is connected between the pressure strip 51 and the protrusion 41. The rotational force can drive the pressure strip 51 to rotate. In the natural state, with the help of the force of the torsion spring 53, the two pressure strips 51 can be fitted together. Moreover, the rotation angle of the torsion spring 53 is greater than 90 degrees, which strengthens the fitting force between the two pressure strips 51, thereby locking one side of the top of the rotor 3 more tightly and ensuring the stability of the rotor 3 during the test.

[0043] Reference Figures 2-7 The bottom of the support rod 6 is provided with a shaft 61. The support rod 6 has an inner groove 601 and a square slot 602. The square slot 602 is located above the shaft 61. The diameter of the circular groove 501 is equal to the outer diameter of the shaft 61, so that the bottom ends of the two pressure strips 51 are joined with the shaft 61 to form a closed space, thereby locking the rotor 3 in it.

[0044] Specifically, the square slot 602 is located above the shaft 61, providing a path for the installation and movement of the locking component 7, ensuring that the locking component 7 can smoothly perform the fixing operation of the pressure strip 51. The circular groove 501 opened at the bottom of the pressure strip 51 has a diameter equal to the outer diameter of the shaft 61. When the two pressure strips 51 rotate and fit together under the action of the torsion spring 53, the circular groove 501 at the bottom of the pressure strip 51 will precisely fit with the shaft 61, so that the bottom ends of the two pressure strips 51 and the shaft 61 together form a closed space. The top of the rotor 3 is firmly locked in this closed space, effectively preventing the rotor 3 from shifting during the test, and further ensuring the stability and reliability of the rotor 3 installation.

[0045] Reference Figures 2-8 The locking component 7 includes a crossbar 71 disposed on one side of the support rod 6, a square rod 72 fixedly connected to the crossbar 71, two shafts 73 respectively located at one end of the crossbar 71, a sleeve rod 74 fixedly connected to the square rod 72, and a return spring 75 connected between the support rod 6 and the crossbar 71.

[0046] Reference Figures 2-7 The sleeve rod 74 is located on the other side of the support rod 6. The square rod 72 passes through the square groove 602 and is fixedly connected to the sleeve rod 74. The sleeve rod 74 and the inner groove 601 have the same shape and size. The bottom end of the sleeve rod 74 is located outside the shaft 61. The diameter of the shaft 73 is the same as the diameter of the through groove 502.

[0047] Specifically, when the sleeve rod 74 is pressed by the top of the rotor 3, it will enter the inner groove 601. At the same time, after the sleeve rod 74 moves, the square rod 72 and the cross rod 71 will move synchronously. After the cross rod 71 deviates from the initial position, it will stretch the return spring 75. When the pressure bar 51 moves back, the rotor 3 loses its compression. The return spring 75 can be used to make the cross rod 71 return to the initial state. The shaft rods 73 at both ends of the cross rod 71 will enter the corresponding through grooves 502, which will fix the pressure bar 51.

[0048] Reference Figures 1-8 The locking rod 8 includes a push rod 81 slidably connected inside the shaft 61. A return spring 82 is connected between the push rod 81 and the shaft 61. The push rod 81 has a vertical slot 801 at one end near the reinforcing member 9 and an arc groove 811 at the other end. When the return spring 82 is not deformed, the width of the arc groove 811 is less than the distance between the arc plate 512 and the pressure strip 51. Therefore, when the push rod 81 is pushed, the push rod 81 will squeeze the arc plate 512 located in the arc groove 811, so that the arc plate 512 is locked, thereby further fixing the pressure strip 51.

[0049] Specifically, push rod 81 is slidably connected inside shaft 61 and can reciprocate within shaft 61. Return spring 82 is connected between push rod 81 and shaft 61, providing return power for push rod 81. Reinforcing member 9 uses vertical slot 801 to fix push rod 81. The shape of arc groove 811 is adapted to the arc disk 512 on one side of pressure bar 51. When push rod 81 is pushed, push rod 81 slides along shaft 61. At this time, arc disk 512 located in arc groove 811 will be squeezed by push rod 81. Due to the dimensional relationship between the width of arc groove 811 and the distance between arc disk 512 and pressure bar 51, the squeezing will deform arc disk 512, thus locking it firmly in arc groove 811, further fixing the position of pressure bar 51 and enhancing the clamping stability of pressure bar 51 on rotor 3. When the external force is removed, push rod 81 will return to its initial position under the action of return spring 82, releasing the lock on arc disk 512.

[0050] Reference Figures 1-9 The connecting rod 10 does not contact the torsion spring 53 and the shaft 73, and one end of the connecting rod 10 is rotatably connected to the outside of the sleeve 511.

[0051] Reference Figures 1-9The reinforcement 9 includes a thin rod 91 slidably connected to one side of the support rod 6, and a weak spring 92 connected between the thin rod 91 and the guard plate 12. The bottom end of the thin rod 91 and the end of the push rod 81 with the vertical slot 801 are both set to be arc-shaped. When the push rod 81 moves, its arc surface will squeeze the arc surface of the thin rod 91, causing the thin rod 91 to move upward and compress the weak spring 92. When the thin rod 91 is aligned with the arc groove 811, the thin rod 91 will enter the arc groove 811, thereby locking the push rod 81 with the thin rod 91. When resetting, the thin rod 91 will be pulled to separate the thin rod 91 from the push rod 81. At this time, the push rod 81 will be pushed back to its original position by the compressed reset spring 82, and then the pressure strip 51 can be reset by the push bar 11.

[0052] The working principle of this invention is as follows: The operator places the top of the rotor 3 between the pressure bar 51 and the support rod 6. The top of the rotor 3 presses against the sleeve rod 74, causing the sleeve rod 74 to enter the inner groove 601. The sleeve rod 74 drives the square rod 72 to move along the square groove opening 602. The square rod 72 pulls the crossbar 71 away from its initial position, stretching the return spring 75. The shaft 73 on the crossbar 71 exits from the through groove 502 of the pressure bar 51, releasing the lock on the pressure bar 51. The torsion spring 53 rotates, and the pressure bar 51 rotates around the circular shaft 52. At the same time, during the rotation of the pressure bar 51, the connecting rod 10 is pulled. The connecting rod 10 drives the push bar 11 to slide along the shaft disc 4. When the top of the rotor 3 is fully inserted, the circular groove 501 at the bottom of the pressure bar 51 and the shaft 61 at the bottom of the support rod 6 are joined together to form a closed space for pressing the top of the rotor 3. Initial locking is achieved at the first level. Subsequently, the operator pushes the push rod 81, which slides along the shaft 61 and compresses the return spring 82. During the movement of the push rod 81, its arc surface presses against the arc surface of the thin rod 91 of the reinforcement 9, causing the thin rod 91 to move upward and compress the weak spring 92. When the thin rod 91 aligns with the vertical slot 801 of the push rod 81, the thin rod 91 enters the vertical slot 801 under the action of the weak spring 92, locking the push rod 81. Furthermore, since the width of the arc groove 811 is less than the distance between the arc plate 512 and the pressure bar 51, the push rod 81 compresses the arc plate 512, firmly locking the arc plate 512 within the arc groove 811, further fixing the pressure bar 51 and completing the second level of locking. This forms a dual locking system of radial fixation and axial limitation, ensuring the stable installation of the rotor 3.

[0053] During reset, the operator pulls the thin rod 91, causing it to exit from the vertical slot 801 of the push rod 81, releasing the lock on the push rod 81. Under the elastic force of the reset spring 82, the push rod 81 slides along the shaft 61 back to its initial position, releasing the pressure of the arc groove 811 on the arc disk 512, and the secondary lock fails. At this time, the push bar 11 is pushed, and the push bar 11 slides along the shaft disk 4 and pulls the connecting rod 10. The connecting rod 10 drives the pressure bar 51 to rotate in the opposite direction around the circular shaft 52. The circular groove 50 at the bottom of the pressure bar 51... 1. Separate from the shaft 61 to release the first-level lock on the rotor 3. At the same time, when the pressure bar 51 rotates, the torsion spring 53 is compressed by rotation. As the pressure bar 51 moves back, the compression of the rotor 3 on the sleeve rod 74 disappears. Under the elastic force of the return spring 75, the cross bar 71 drives the square bar 72 and the sleeve rod 74 to return to the initial position. The sleeve rod 74 exits the inner groove 601. The shaft 73 on the cross bar 71 is reinserted into the through groove 502 of the pressure bar 51 to fix the pressure bar 51. The rotor 3 can then be taken out and wait for the next test operation.

[0054] Example 2, refer to 1- Figure 9 The second embodiment of the present invention provides a manufacturing process for a respirator winding composite gas cylinder, which employs a resin viscosity testing device and includes the following steps:

[0055] Step 1: Test the resin viscosity using the drive tester 2 and rotor 3 to ensure the resin's adhesion. At the same time, adjust the resin according to the ratio and remove air bubbles to ensure its flowability and wettability meet the winding requirements. Prepare the cleaned inner lining to ensure that the carbon fiber quality and winding parameters meet the requirements.

[0056] Step 2: Impregnate the carbon fibers with the prepared resin system containing carbon nanotubes to allow the resin to fully penetrate the carbon fibers.

[0057] Step 3: After impregnating the pretreated fibers with resin using a winding machine, the fibers are precisely wound onto the inner lining surface of the gas cylinder along a preset path. The viscosity characteristics of the resin are used to ensure that the fibers are fully impregnated and evenly distributed, forming the blank of the composite gas cylinder.

[0058] Step Four: The wound cylinder blank is placed in a curing oven and cured according to a specific temperature curve. By controlling the curing time and temperature, the resin is fully cross-linked and hardened, firmly bonding the fiber and lining into a whole, forming stable mechanical properties. Ensuring complete resin curing yields the final wound composite gas cylinder. Simultaneously, the cured cylinder undergoes post-treatment such as trimming and polishing to remove excess material and refine its appearance. Following this, comprehensive testing is conducted, including hydrostatic testing, airtightness testing, and ultrasonic flaw detection, to verify the cylinder's pressure resistance, structural integrity, and safety. Only after passing these tests can the cylinder be shipped and put into use.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
