Description

Technical Field

[0001] The invention belongs to the technical field of glass fiber testing, in particular to a continuous glass fiber weather resistance testing device. Background Art

[0002] Continuous glass fiber is an inorganic non-metallic material made from high-purity glass through stretching, and has excellent physical and chemical properties. Continuous glass fiber refers to a long and continuous fiber made directly from molten glass or drawn from molten glass balls, rods, etc., with a diameter usually between 10 and 20 microns and a slender cylindrical structure. When testing the performance of continuous glass fiber, its weather resistance is often tested, that is, by simulating different temperature and humidity environments to test the material properties of the glass fiber.

[0003] The weather resistance test device currently used for glass fiber is mainly composed of a clamping device and a testing device. When in use, a section of glass fiber is taken and placed in the clamping device. The glass fiber is fixed by manipulating the clamping device, and finally placed in a test box. The glass fiber is tested at different temperatures. This test method requires the clamping device to be operated before and after the test to achieve the fixing and releasing process of the glass fiber, which seriously affects the test efficiency during batch testing.

[0004] At the same time, the glass fiber is in a stationary state inside the test box during the test in the currently used test device. This test method requires a tensile test to be carried out later to test the tensile strength of the glass fiber under different environments. However, since the subsequent experiments have been separated from the current test environment, the data measured in the subsequent experiments have certain inaccuracies, which also affects the overall test efficiency. Summary of the invention

[0005] The object of the present invention is to provide a continuous glass fiber weather resistance testing device to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a continuous glass fiber weather resistance testing device, comprising a base, a cam divider is fixedly installed on the top of the base, a cylinder is fixedly installed on the output end of the cam divider, a mounting frame is fixedly installed on the output end of the cylinder, a turntable is axially evenly installed on the outer side of the mounting frame, slots are provided on both sides of the top of the turntable, a clamping assembly is movably connected inside the slot, a stretching assembly is installed on the bottom end of the turntable, the top of the stretching assembly is connected to the clamping assembly, and the base A frame is fixedly installed on one side, and a test box located directly above the turntable is fixedly installed on the top of the frame, a mixing box is fixedly connected to the middle of the top of the test box, and a three-way valve is fixedly connected to the top of the mixing box. A limit plate is installed in the middle of the inner side of the test box, and lateral guide rails are installed on the front and rear sides of the outer side of the test box. A main shaft is movably connected to the middle of the mixing box, and a power assembly located on one side of the lateral guide rail is installed on the front and rear ends of the main shaft. The power assembly is movably connected to the lateral guide rail, and the single rotation angle of the cam divider is one hundred and twenty degrees.

[0007] In actual use, the continuous glass fiber to be tested can be prepared. A section of the continuous glass fiber needs to be taken, and the three turntables are respectively corresponding to the loading, testing, and unloading positions. Three operators work together and prepare external high-speed hot air blowers and high-speed cold air blowers to complete the preliminary preparations before the test.

[0008] As a further technical solution of the present invention, the middle part of the main shaft is fixedly sleeved with an impeller located inside the mixing box, and the front and rear ends of the three-way valve are respectively connected to the high-speed hot air blower and the high-speed cold air blower.

[0009] Before the test, the external high-speed cooling air fan and high-speed hot air fan must be adjusted according to the required test environment to ensure that the hot air and cold air blown by the two can enter the interior of the three-way valve and form the environmental temperature required for the test after mixing inside the mixing box.

[0010] As a further technical solution of the present invention, the clamping assembly includes a card block, which is movably connected to the card slot, and a clamping block is provided directly above the card block. Extended ear plates are installed on both sides of the clamping block, and a guide rod is movably sleeved inside the extended ear plate.

[0011] As a further technical solution of the present invention, the extended ear plate moves up and down relative to the guide rod, the bottom end of the guide rod is connected to both sides of the top of the block, the outer side surface of the guide rod is movably sleeved with a limit spring, and the upper and lower ends of the limit spring are respectively connected to the bottom end of the extended ear plate and the top of the block.

[0012] As a further technical solution of the present invention, the top end of the guide rod passes through the top end of the extended ear plate and is fixedly connected to the limiting plate, anti-slip grooves are provided between the clamping block and the clamping block, an extension seat is fixedly installed in the middle of the top end of the clamping block, and an auxiliary wheel is movably installed at the top end of the extension seat.

[0013] As a further technical solution of the present invention, when the cylinder is extended to the extreme position, the top of the turntable completely enters the interior of the test box, and the bottom end of the turntable and the bottom end of the test box are on the same plane, and the outer side surface of the turntable contacts the inner side surface of the test box, and during the rising process of the turntable, the outer side surface of the auxiliary wheel contacts the bottom end of the limit plate, and when the turntable rises to the highest point, the auxiliary wheel approaches the block under the action of the limit plate and the distance between the two is reduced to the minimum value.

[0014] When testing glass fiber, the glass fiber to be tested can be placed between the two clamping components at the loading station, that is, the two ends of the glass fiber are placed between the two clamping blocks and the clamping blocks respectively. After the placement is completed, the cam divider can be started to drive the upper turntable to rotate until the turntable loaded with glass fiber rotates to the bottom of the test box. At this time, the cylinder can be started to drive the mounting frame and the turntable to rise until the top of the turntable rises to the inside of the test box, and finally the bottom end of the turntable and the bottom end of the test box are on the same plane, completing the sealing process of the bottom end of the test box;

[0015] When the turntable moves upward, the clamping assembly rises accordingly until the outer side of the auxiliary wheel contacts the bottom end of the limit plate, and as the turntable continues to rise, the limit plate can apply downward pressure to the auxiliary wheel, and the auxiliary wheel and the extension seat fall accordingly, and drive the clamping block to move downward, and the limit spring is compressed accordingly, and drives the extended ear plate to move downward relative to the clamping block, and the auxiliary wheel can roll relative to the limit plate when the clamping block moves left and right, and always maintains contact with the limit plate, and as the distance between the clamping block and the clamping block is reduced, the two ends of the glass fiber can be clamped between the two clamping blocks and the clamping block to complete the clamping process;

[0016] When the glass fiber test is completed, the cylinder can be turned on to control the turntable to descend. At this time, the limit plate no longer applies pressure to the clamping assembly. The limit spring automatically resets and drives the clamping block to automatically rise. At this time, the distance between the clamping block and the clamping block increases accordingly, and no pressure is applied to the two ends of the glass fiber, and the clamping process of the glass fiber is automatically released.

[0017] By setting the clamping assembly and the limit plate, and coordinating the rotation and rising process of the turntable, the limit plate can automatically apply pressure to the clamping assembly, that is, the glass fiber is automatically clamped during the test, and the clamping state is automatically released after the test. The whole process is completed automatically without manual control, so that the device does not need to be manually clamped and released during loading and unloading, which significantly shortens the loading and unloading time and improves the test efficiency.

[0018] As a further technical solution of the present invention, the stretching assembly includes a movable plate, a telescopic rod is installed in the middle of the top of the movable plate, the top of the telescopic rod is connected to the middle of the bottom of the turntable, and a transmission sleeve is vertically installed in the middle of the bottom of the movable plate. When the telescopic rod is in an initial state, the distance between the movable plate and the turntable is a maximum.

[0019] As a further technical solution of the present invention, a first fixed seat is installed on both sides of the left and right sides of the top of the movable plate, the first fixed seat is movably connected to a linkage rod on the side away from the movable plate through a rotating shaft, the linkage rod is movably connected to a second fixed seat on the side away from the first fixed seat through a rotating shaft, and the top of the second fixed seat is connected to the middle of the bottom end of the block.

[0020] In the initial state, that is, after the glass fiber is clamped, the telescopic rod is in the initial state, that is, the movable plate is at the lowest point and the transmission sleeve is also at the lowest point. At this time, the glass fiber sample is in the shortest state, that is, the initial state. When the transmission sleeve moves upward under the action of the power component, the telescopic rod can be shortened and drives the movable plate to move up. At this time, the two linkage rods are deflected, that is, the angle between the two linkage rods is increased, and a thrust is applied to the two blocks. At this time, the two blocks are relatively separated, and the glass fiber between the two blocks can be stretched to complete the stretching test. The reciprocating up and down displacement of the transmission sleeve can be realized through the action of the power component, and the reciprocating stretching and contraction of the glass fiber can be realized to complete the automatic stretching experiment process.

[0021] As a further technical solution of the present invention, the power assembly includes a first connecting rod, the first connecting rod is fixedly connected to one end of the main shaft, the end of the first connecting rod away from the main shaft is movably connected to the second connecting rod through a rotating shaft, the end of the second connecting rod away from the first connecting rod is movably connected to a fixed seat located on one side of the lateral guide rail through a rotating shaft, and an extension socket is installed at the end of the fixed seat close to the lateral guide rail, the extension socket is movably engaged with the lateral guide rail and can move up and down relative to the lateral guide rail, the extension socket is located on one side of the lateral guide rail and is fixedly installed with an electric push rod near the bottom end, and the output end of the electric push rod is fixedly installed with a transmission shaft compatible with the transmission sleeve.

[0022] As a further technical solution of the present invention, when the telescopic rod is in the initial state, the transmission sleeve is in the lowest point state, and when the bottom end of the turntable and the bottom end of the test box are in the same plane, the middle part of the transmission sleeve and the middle part of the transmission shaft are on the same central axis.

[0023] When the bottom of the turntable and the bottom of the test box are in the same plane, that is, when all the glass fiber samples enter the test box, the device is in the test state, and the transmission sleeve just corresponds to the transmission shaft. At this time, the electric push rod can be turned on to drive the transmission shaft to move, and drive the transmission shaft to insert into the transmission sleeve to complete the clamping process with the transmission sleeve. At this time, the power transmission between the power component and the tensile component can be realized;

[0024] At the same time, the mixed air can be introduced into the interior of the mixing box and into the interior of the test box by mixing the external high-speed hot air blower and the high-speed cold air blower, so as to change the temperature environment inside the test box and meet the test requirements. At the same time, when the high-speed air enters the mixing box, it can drive the impeller to rotate and drive the main shaft to rotate. When the main shaft rotates, it can drive the first connecting rod to rotate. At this time, the second connecting rod swings accordingly, and applies a downward thrust and an upward pull to the fixed seat. Under the guidance of the extension card seat and the lateral guide rail, the extension card seat is driven to reciprocate up and down, and the transmission shaft is driven to reciprocate up and down synchronously, that is, the reciprocating up and down displacement of the transmission sleeve is realized synchronously, and the stretching component is cooperated to automatically realize the stretching experiment inside the test box.

[0025] By utilizing the external air input to change the test environment during the glass fiber test, and coordinating with the automatic clamping of the clamping assembly and the automatic rise of the turntable, automatic sealing during the test is achieved. While changing the internal environment of the test box, the flowing air is used to transmit power to the tensile assembly, thereby completing the automatic tensile experiment under the test environment, ensuring the accuracy of the test data and improving the test efficiency.

[0026] During the test, the three turntables can work together at the same time, that is, when the turntable drops to the lowest point, the turntable at the loading station can load the glass fiber, and the turntable at the testing station is located directly below the test box waiting for testing. The turntable at the unloading station has completed the test process and the clamping assembly no longer clamps the turntable. At this time, the glass fiber can be directly taken out to complete the unloading. Through the equal-angle rotation of the cam divider and the rising and falling process of the turntable, loading, waiting for testing, and unloading can be completed at the same time.

[0027] Through the coordination between the cam divider, the cylinder and the turntable, as well as the coordination between the stretching assembly, the test box and the power assembly, the device can simultaneously perform the loading, waiting for testing and unloading processes when the turntable is at the lowest point, and when the turntable is at the highest point, it can also automatically realize the clamping and automatic stretching test processes. The entire test process has a high degree of automation, which significantly shortens the preparation time for batch experiments and improves the test efficiency during batch testing.

[0028] The beneficial effects of the present invention are as follows:

[0029] 1. The present invention provides a clamping assembly and a limit plate, and cooperates with the rotation and rising process of the turntable to automatically realize that the limit plate applies pressure to the clamping assembly, that is, the glass fiber is automatically clamped during testing, and the clamping state is automatically released after the test. The whole process is completed automatically without manual control, so that the device does not need to be manually clamped and released when loading and unloading, which significantly shortens the loading and unloading time and improves the test efficiency.

[0030] 2. The present invention utilizes the external air input during the glass fiber test to change the test environment, cooperates with the automatic clamping of the clamping assembly, and the automatic rise of the turntable to achieve automatic sealing during the test, and while changing the internal environment of the test box, utilizes the flowing air to achieve power transmission to the stretching assembly, thereby completing the automatic stretching experiment under the test environment, ensuring the accuracy of the test data and improving the test efficiency.

[0031] 3. The present invention achieves coordination between the cam divider, the cylinder and the turntable, as well as coordination between the stretching assembly, the test box and the power assembly, so that when the turntable is at the lowest point, the device can simultaneously perform the loading, waiting for testing and unloading processes, and when the turntable is at the highest point, it can also automatically realize the clamping and automatic stretching test processes. The entire test process has a high degree of automation, which significantly shortens the preparation time for batch experiments and improves the test efficiency during batch testing.

[0044] In actual use, the continuous glass fiber to be tested can be prepared. A section of the continuous glass fiber needs to be taken, and the three turntables 6 are respectively corresponding to the three stations of loading, testing, and discharging. Three operators work together, and external high-speed hot air blowers and high-speed cold air blowers are prepared to complete the preliminary preparations before the test.

[0045] like Figure 3 and Figure 5 as well as Figure 6 As shown, the middle part of the main shaft 16 is fixedly sleeved with an impeller 15 located inside the mixing box 14, and the front and rear ends of the three-way valve 13 are respectively connected to the high-speed hot air blower and the high-speed cold air blower.

[0046] Before the test, the external high-speed cooling air blower and high-speed hot air blower need to be adjusted according to the required test environment to ensure that the hot air and cold air blown by the two can enter the interior of the three-way valve 13 and form the required environmental temperature for the test after mixing in the mixing box 14.

[0047] like Figure 1 and Figure 7 as well as Figure 8 and Fig. 9As shown, the clamping assembly 8 includes a clamping block 801, which is movably clamped with the clamping slot 7. A clamping block 802 is provided directly above the clamping block 801, and extended ear plates 803 are installed on the left and right sides of the clamping block 802. The inner part of the extended ear plate 803 is movably sleeved with a guide rod 804, and the extended ear plate 803 moves up and down relative to the guide rod 804. The bottom end of the guide rod 804 is connected to the two sides of the top of the clamping block 801, and the outer side surface of the guide rod 804 is movably sleeved with a limit spring 806. The upper and lower ends of the limit spring 806 are respectively connected to the bottom end of the extended ear plate 803 and the top of the clamping block 801, and the top of the guide rod 804 passes through the top of the extended ear plate 803 and is fixedly connected to the limit plate 805, anti-slip grooves are provided between the clamping block 802 and the clamping block 801, an extension seat 807 is fixedly installed in the middle of the top of the clamping block 802, and an auxiliary wheel 808 is movably installed on the top of the extension seat 807. When the cylinder 4 is extended to the limit position, the top of the turntable 6 completely enters the interior of the test box 10, and the bottom end of the turntable 6 and the bottom end of the test box 10 are on the same plane, and the outer side surface of the turntable 6 is in contact with the inner side surface of the test box 10. During the rising process of the turntable 6, the outer side surface of the auxiliary wheel 808 is in contact with the bottom end of the limit plate 11, and when the turntable 6 rises to the highest point, the auxiliary wheel 808 approaches the clamping block 801 under the action of the limit plate 11 and the distance between the two is reduced to the minimum value.

[0048] Embodiment: When testing glass fibers, the glass fibers to be tested can be placed between the two clamping assemblies 8 at the loading station, that is, the two ends of the glass fibers are placed between the two clamping blocks 801 and the clamping blocks 802, respectively. After the placement is completed, the cam divider 3 can be started to drive the upper turntable 6 to rotate until the turntable 6 loaded with the glass fibers rotates to the bottom of the test box 10. At this time, the cylinder 4 can be started to drive the mounting frame 5 and the turntable 6 to rise until the top of the turntable 6 rises to the inside of the test box 10, and finally the bottom end of the turntable 6 and the bottom end of the test box 10 are on the same plane, completing the sealing process of the bottom end of the test box 10;

[0049] When the turntable 6 moves upward, the clamping assembly 8 rises accordingly until the outer side surface of the auxiliary wheel 808 contacts the bottom end of the limit plate 11, and as the turntable 6 continues to rise, the limit plate 11 can apply downward pressure to the auxiliary wheel 808, and the auxiliary wheel 808 and the extension seat 807 fall accordingly, and drive the clamping block 802 to move downward, and the limit spring 806 is compressed accordingly, and drives the extended ear plate 803 to move downward relative to the clamping block 801, and the auxiliary wheel 808 can roll relative to the limit plate 11 when the clamping block 801 moves left and right, and always maintains contact with the limit plate 11, and as the distance between the clamping block 801 and the clamping block 802 is reduced, the two ends of the glass fiber can be clamped between the two clamping blocks 801 and the clamping block 802 to complete the clamping process;

[0050] When the test of the glass fiber is completed, the cylinder 4 can be turned on to control the turntable 6 to descend. At this time, the limit plate 11 no longer applies pressure to the clamping assembly 8. At this time, the limit spring 806 automatically resets and drives the clamping block 802 to automatically rise. At this time, the distance between the clamping block 802 and the clamping block 801 increases accordingly, and no pressure is applied to the two ends of the glass fiber, and the clamping process of the glass fiber is automatically released.

[0051] By setting the clamping assembly 8 and the limit plate 11, and coordinating the rotation and rising process of the turntable 6, the limit plate 11 can automatically apply pressure to the clamping assembly 8, that is, the glass fiber is automatically clamped during testing, and the clamping state is automatically released after the test. The whole process is completed automatically without manual control, so that the device does not need to be manually clamped and released during loading and unloading, which significantly shortens the loading and unloading time and improves the test efficiency.

[0052] like Figure 1 and Figure 7 as well as Figure 8 As shown, the stretching assembly 9 includes a movable plate 901, a telescopic rod 902 is installed in the middle of the top of the movable plate 901, the top of the telescopic rod 902 is connected to the middle of the bottom of the turntable 6, a transmission sleeve 906 is vertically installed in the middle of the bottom of the movable plate 901, when the telescopic rod 902 is in the initial state, the distance between the movable plate 901 and the turntable 6 is the maximum value, and the left and right sides of the top of the movable plate 901 are installed with a first fixed seat 903, the side of the first fixed seat 903 away from the movable plate 901 is movably connected to a linkage rod 905 through a rotating shaft, and the side of the linkage rod 905 away from the first fixed seat 903 is movably connected to a second fixed seat 904 through a rotating shaft, and the top of the second fixed seat 904 is connected to the middle of the bottom end of the block 801.

[0053] In the initial state, that is, after the glass fiber is clamped, the telescopic rod 902 is in the initial state, that is, the movable plate 901 is at the lowest point and the transmission sleeve 906 is also at the lowest point. At this time, the glass fiber sample is in the shortest state, that is, the initial state. When the transmission sleeve 906 moves upward under the action of the power component 17, the telescopic rod 902 can be shortened and drives the movable plate 901 to move upward. At this time, the two linkage rods 905 are deflected accordingly, that is, the angle between the two linkage rods 905 is increased, and a thrust is applied to the two blocks 801. At this time, the two blocks 801 are relatively separated, and the glass fiber located between the two blocks 801 can be stretched to complete the stretching test. The reciprocating up and down displacement of the transmission sleeve 906 can be realized through the action of the power component 17, and the reciprocating stretching and contraction of the glass fiber can be realized to complete the automatic stretching experiment process.

[0054] like Figure 1 and Figure 3 as well as Figure 5 As shown, the power assembly 17 includes a first connecting rod 171, the first connecting rod 171 is fixedly connected to one end of the main shaft 16, the end of the first connecting rod 171 away from the main shaft 16 is movably connected to the second connecting rod 172 through a rotating shaft, and the end of the second connecting rod 172 away from the first connecting rod 171 is movably connected to a fixing seat 173 located on one side of the lateral guide rail 12 through a rotating shaft, and the end of the fixing seat 173 close to the lateral guide rail 12 is installed with an extension seat 174, and the extension seat 174 is movably connected to the lateral guide rail 12. And relative to the lateral guide rail 12, the extended card seat 174 is located on one side of the lateral guide rail 12 and is fixedly installed with an electric push rod 175 near the bottom end. The output end of the electric push rod 175 is fixedly installed with a transmission shaft 176 adapted to the transmission sleeve 906. When the telescopic rod 902 is in the initial state, the transmission sleeve 906 is in the lowest point state, and when the bottom end of the turntable 6 and the bottom end of the test box 10 are in the same plane, the middle part of the transmission sleeve 906 and the middle part of the transmission shaft 176 are on the same central axis.

[0055] Embodiment: When the bottom end of the turntable 6 and the bottom end of the test box 10 are in the same plane, that is, when all the glass fiber samples enter the test box 10, the device is in the test state, and the transmission sleeve 906 just corresponds to the transmission shaft 176. At this time, the electric push rod 175 can be turned on to drive the transmission shaft 176 to move, and drive the transmission shaft 176 to insert into the transmission sleeve 906, completing the clamping process with the transmission sleeve 906, and at this time, the power transmission between the power component 17 and the stretching component 9 can be realized;

[0056] At the same time, the mixed air can be introduced into the interior of the mixing box 14 and into the interior of the test box 10 by mixing the external high-speed hot air blower and the high-speed cold air blower, so as to change the temperature environment inside the test box 10 and meet the test requirements. At the same time, when the high-speed air enters the mixing box 14, it can drive the impeller 15 to rotate and drive the main shaft 16 to rotate. When the main shaft 16 rotates, it can drive the first connecting rod 171 to rotate. At this time, the second connecting rod 172 swings accordingly, and applies a downward thrust and an upward pull to the fixed seat 173, and drives the extended card seat 174 to reciprocate up and down under the guidance of the extended card seat 174 and the lateral guide rail 12, and synchronously drives the transmission shaft 176 to reciprocate up and down, that is, synchronously realizes the reciprocating up and down displacement of the transmission sleeve 906, and cooperates with the stretching component 9 to automatically realize the stretching experiment inside the test box 10.

[0057] By utilizing the external air input to change the test environment during the glass fiber test, and cooperating with the automatic clamping of the clamping assembly 8 and the automatic rise of the turntable 6, automatic sealing during the test is achieved, and while changing the internal environment of the test box 10, the flowing air is used to realize the power transmission to the stretching assembly 9, thereby completing the automatic stretching experiment under the test environment, ensuring the accuracy of the test data and improving the test efficiency.

[0058] During the test, the three turntables 6 can work together at the same time, that is, when the turntable 6 drops to the lowest point, the turntable 6 located at the loading station can load the glass fiber, and the turntable 6 located at the testing station is located directly below the test box 10 waiting for testing. The turntable 6 located at the unloading station has completed the test process and the clamping assembly 8 no longer clamps the turntable 6. At this time, the glass fiber can be directly taken out to complete the unloading. By rotating the cam divider 3 at equal angles and coordinating the rising and falling processes of the turntable 6, loading, waiting for testing, and unloading can be completed at the same time.

[0059] Through the cooperation between the cam divider 3, the cylinder 4 and the turntable 6, and the cooperation between the stretching component 9, the test box 10 and the power component 17, the device can simultaneously perform the loading, waiting for testing and unloading processes when the turntable 6 is at the lowest point, and when the turntable 6 is at the highest point, it can also automatically realize the clamping and automatic stretching test processes. The entire test process has a high degree of automation, which significantly shortens the preparation time for batch experiments and improves the test efficiency during batch testing.

[0060] Working principle and usage process:

[0061] In actual use, the continuous glass fiber to be tested can be prepared. A section of the continuous glass fiber needs to be taken, and the three turntables 6 correspond to the three positions of loading, testing, and discharging respectively. Three operators work together, and external high-speed hot air blowers and high-speed cold air blowers are prepared at the same time to complete the preliminary preparations before the test;

[0062] Before the test, the external high-speed cooling air blower and high-speed hot air blower need to be adjusted according to the required test environment to ensure that the hot air and cold air blown by the two can enter the interior of the three-way valve 13 and form the required environmental temperature for the test after being mixed in the mixing box 14;

[0063] When testing the glass fiber, the glass fiber to be tested can be placed between the two clamping assemblies 8 at the loading station, that is, the two ends of the glass fiber are placed between the two clamping blocks 801 and the clamping block 802 respectively. After the placement is completed, the cam divider 3 can be started to drive the upper turntable 6 to rotate until the turntable 6 loaded with the glass fiber rotates to the bottom of the test box 10. At this time, the cylinder 4 can be started to drive the mounting frame 5 and the turntable 6 to rise until the top of the turntable 6 rises to the inside of the test box 10, and finally the bottom end of the turntable 6 and the bottom end of the test box 10 are on the same plane, completing the sealing process of the bottom end of the test box 10;

[0064] When the turntable 6 moves upward, the clamping assembly 8 rises accordingly until the outer side surface of the auxiliary wheel 808 contacts the bottom end of the limit plate 11, and as the turntable 6 continues to rise, the limit plate 11 can apply downward pressure to the auxiliary wheel 808, and the auxiliary wheel 808 and the extension seat 807 fall accordingly, and drive the clamping block 802 to move downward, and the limit spring 806 is compressed accordingly, and drives the extended ear plate 803 to move downward relative to the clamping block 801, and the auxiliary wheel 808 can roll relative to the limit plate 11 when the clamping block 801 moves left and right, and always maintains contact with the limit plate 11, and as the distance between the clamping block 801 and the clamping block 802 is reduced, the two ends of the glass fiber can be clamped between the two clamping blocks 801 and the clamping block 802 to complete the clamping process;

[0065] When the bottom end of the turntable 6 and the bottom end of the test box 10 are in the same plane, that is, when all the glass fiber samples enter the test box 10, the device is in the test state, and the transmission sleeve 906 just corresponds to the transmission shaft 176. At this time, the electric push rod 175 can be turned on to drive the transmission shaft 176 to move, and drive the transmission shaft 176 to insert into the transmission sleeve 906, completing the clamping process with the transmission sleeve 906, and at this time, the power transmission between the power component 17 and the stretching component 9 can be realized;

[0066] In the initial state, that is, after the glass fiber is clamped, the telescopic rod 902 is in the initial state, that is, the movable plate 901 is at the lowest point and the transmission sleeve 906 is also at the lowest point. At this time, the glass fiber sample is in the shortest state, that is, the initial state. When the transmission sleeve 906 moves upward under the action of the power component 17, the telescopic rod 902 can be shortened and drives the movable plate 901 to move upward. At this time, the two linkage rods 905 are deflected accordingly, that is, the angle between the two linkage rods 905 is increased, and a thrust is applied to the two blocks 801. At this time, the two blocks 801 are relatively separated, and the glass fiber between the two blocks 801 can be stretched to complete the stretching test. The reciprocating up and down displacement of the transmission sleeve 906 can be realized through the action of the power component 17, and the reciprocating stretching and contraction of the glass fiber can be realized to complete the automatic stretching experiment process;

[0067] At the same time, the mixed air can be introduced into the interior of the mixing box 14 and into the interior of the test box 10 by mixing the external high-speed hot air blower and the high-speed cold air blower, so as to change the temperature environment inside the test box 10 and meet the test requirements. At the same time, when the high-speed air enters the mixing box 14, it can drive the impeller 15 to rotate and drive the main shaft 16 to rotate. When the main shaft 16 rotates, it can drive the first connecting rod 171 to rotate. At this time, the second connecting rod 172 swings accordingly, and applies a downward thrust and an upward pull to the fixed seat 173. Under the guidance of the extended card seat 174 and the lateral guide rail 12, the extended card seat 174 is driven to move up and down reciprocatingly, and the transmission shaft 176 is driven to move up and down reciprocatingly synchronously, that is, the reciprocating up and down displacement of the transmission sleeve 906 is synchronously realized, and the tensile test is automatically realized inside the test box 10 in cooperation with the tensile assembly 9;

[0068] When the glass fiber test is completed, the cylinder 4 can be turned on to control the turntable 6 to descend. At this time, the limit plate 11 no longer applies pressure to the clamping assembly 8. At this time, the limit spring 806 automatically resets and drives the clamping block 802 to automatically rise. At this time, the distance between the clamping block 802 and the clamping block 801 increases accordingly, and no pressure is applied to the two ends of the glass fiber, and the clamping process of the glass fiber is automatically released;

[0069] During the test, the three turntables 6 can work together at the same time, that is, when the turntable 6 drops to the lowest point, the turntable 6 located at the loading station can load the glass fiber, and the turntable 6 located at the testing station is located directly below the test box 10 waiting for testing. The turntable 6 located at the unloading station has completed the test process and the clamping assembly 8 no longer clamps the turntable 6. At this time, the glass fiber can be directly taken out to complete the unloading. By rotating the cam divider 3 at equal angles and coordinating the rising and falling processes of the turntable 6, loading, waiting for testing, and unloading can be completed at the same time.
