Description

Technical Field

[0001] The present invention belongs to the technical field of glass fiber testing, and specifically relates to a weather resistance testing device for continuous glass fibers. Background Art

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

[0003] Currently, the weather resistance testing devices used for glass fibers mainly consist of a clamping device and a testing device. When in use, a section of glass fiber is taken and placed in the clamping device, and the glass fiber is fixed by controlling the clamping device. Finally, it is placed in a testing chamber, and the testing process of the glass fiber is realized by different temperatures. This testing method requires operations on the clamping device before and after testing to fix and release the glass fiber. During batch testing, the testing efficiency is seriously affected.

[0004] At the same time, the glass fiber in the current testing device is in a static state inside the testing chamber during testing. This testing method also requires a tensile experiment in the later stage to test the tensile strength of the glass fiber in different environments. However, since the subsequent experiment is out of the current testing environment, the data measured in the subsequent experiment is somewhat inaccurate, and the overall testing efficiency is also affected. Summary of the Invention

[0005] The purpose of the present invention is to provide a weather resistance testing device for continuous glass fibers to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A continuous glass fiber weather resistance testing device, including a base, on the top of the base is fixedly installed a cam divider, the output end of the cam divider is fixedly installed with a cylinder, the output end of the cylinder is fixedly installed with a mounting frame, on the outer side surface of the mounting frame are axially equidistantly installed turntables, on both sides of the top of each turntable are provided card slots, inside the card slots are movably clamped clamping components, at the bottom of the turntable is installed a stretching component, the top of the stretching component is connected to the clamping component, on one side of the base is fixedly installed a frame, on the top of the frame is fixedly installed a testing box located directly above the turntable, in the middle of the top of the testing box is fixedly communicated with a mixing box, on the top of the mixing box is fixedly communicated with a three-way valve, in the middle of the inner side surface of the testing box is installed a first limiting plate, on the front and rear sides of the outer side surface of the testing box are installed lateral guide rails, in the middle of the mixing box is movably connected a main shaft, at both ends of the front and rear of the main shaft are installed power components located on one side of the lateral guide rails, the power components are movably clamped with the lateral guide rails, and the single rotation angle of the cam divider is one hundred and twenty degrees.

[0007] During actual use, continuous glass fibers to be tested can be prepared. A section of the continuous glass fibers needs to be taken, and the three turntables are respectively corresponding to the feeding, testing, and discharging stations, and three operators work together. At the same time, an external high-speed hot air blower and a high-speed cold air blower are prepared to complete the preliminary preparation before the test.

[0008] As a further technical solution of the present invention, in the middle 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 cold 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 inside 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 component includes a clamping block, the clamping block is movably clamped with the card slot, above the clamping block is provided a clamping plate, on the left and right sides of the clamping plate are installed extended ear plates, and inside the extended ear plates are movably sleeved with guide rods.

[0011] As a further technical solution of the present invention, the extended ear plates displace up and down relative to the guide rods, the bottom ends of the guide rods are connected to both sides of the top of the clamping block, and on the outer side surface of the guide rods are movably sleeved with limiting springs, and the upper and lower ends of the limiting springs are respectively connected to the bottom end of the extended ear plate and the top of the clamping block.

[0012] As a further technical solution of the present invention, the top end of the guiding rod penetrates through the top end of the extended ear plate and is fixedly connected with a second limiting plate. Anti-slip grooves are formed between the clamping blocks and the clamping blocks. The middle part of the top end of the clamping block is fixedly installed with an extended seat, and an auxiliary wheel is movably installed at the top end of the extended seat.

[0013] As a further technical solution of the present invention, when the cylinder extends to the limit position, the top end of the turntable completely enters the inside of the test box, and the bottom end of the turntable is on the same plane as the bottom end of the test box, and the outer side surface of the turntable is in contact with the inner side surface of the test box. During the rising process of the turntable, the outer side surface of the auxiliary wheel is in contact with the bottom end of the first limiting plate, and when the turntable rises to the highest point, the auxiliary wheel approaches the clamping block under the action of the first limiting 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 assemblies at the loading station, that is, the two ends of the glass fiber are respectively placed at the positions between the two clamping blocks and the clamping blocks. 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 directly below the test box. At this time, the cylinder can be opened to drive the mounting frame and the turntable to rise until the top end of the turntable rises into the inside of the test box, and finally the bottom end of the turntable is on the same plane as the bottom end of the test box, 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 surface of the auxiliary wheel is in contact with the bottom end of the first limiting plate. As the turntable continues to rise, the first limiting plate can apply a downward pressure to the auxiliary wheel. At this time, the auxiliary wheel and the extended seat descend accordingly, driving the clamping block to move downward. At this time, the limiting spring is compressed, driving the extended ear plate to move downward relative to the clamping block. The auxiliary wheel can roll relative to the first limiting plate when the clamping block moves left and right and always remains in contact with the first limiting plate. As the distance between the clamping block and the clamping block decreases, the two ends of the glass fiber can be clamped between the two clamping blocks and the clamping blocks to complete the clamping process;

[0016] When the test of the glass fiber is completed, the cylinder can be opened to control the turntable to descend. At this time, the first limiting plate no longer applies pressure to the clamping assembly. At this time, the limiting spring automatically resets, driving the clamping block to rise automatically. At this time, the distance between the clamping block and the clamping block increases, no longer applying pressure to the two ends of the glass fiber, and automatically releasing the clamping process of the glass fiber.

[0017] By setting the clamping assembly and the first limiting plate, and cooperating with the rotation and rising process of the turntable, the first limiting plate can automatically apply pressure to the clamping assembly. That is, when testing the glass fiber, the clamping process is automatically realized. At the same time, after the test is completed, the clamping state is automatically released. The whole process is automatically completed without manual control, so that the device does not need to be manually clamped and released during loading and unloading, significantly shortening the loading and unloading time and improving 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 end of the movable plate, and the top end of the telescopic rod is connected to the middle of the bottom end of the turntable. A transmission sleeve is vertically installed in the middle of the bottom end of the movable plate. When the telescopic rod is in the initial state, the distance between the movable plate and the turntable is the maximum value.

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

[0020] In the initial state, that is, after the glass fiber is clamped, at this time the telescopic rod is in the initial state, that is, at this time 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 assembly, the telescopic rod can be shortened at this time, and the movable plate is driven to move upward. At this time, the two linkage rods deflect accordingly, that is, the included angle between the two linkage rods is increased, and a thrust is applied to the two clamping blocks. At this time, the two clamping blocks move relatively away from each other, and the glass fiber located between the two clamping blocks can be stretched to complete the tensile test. Through the action of the power assembly, the reciprocating up and down displacement of the transmission sleeve can be realized, 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. One end of the first connecting rod away from the main shaft is movably connected to a second connecting rod through a rotating shaft. One end of each second connecting rod away from the first connecting rod is movably connected to a fixing seat located on one side of the lateral guide rail through a rotating shaft. An extended clamping seat is installed at one end of each fixing seat close to the lateral guide rail. The extended clamping seat is movably clamped with the lateral guide rail and moves up and down relative to the lateral guide rail. An electric push rod is fixedly installed at a position on one side of the extended clamping seat close to the bottom end of the lateral guide rail. The output end of the electric push rod is fixedly installed with a transmission shaft adapted to 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 state, and when the bottom end of the turntable is in the same plane as the bottom end of the test box, the middle of the transmission sleeve and the middle of the transmission shaft are on the same central axis.

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

[0024] At the same time, by mixing the external high-speed hot air blower and the high-speed cold air blower, the mixed air can be introduced into the interior of the mixing box and enter the interior of the test box to change the temperature environment inside the test box to meet the test requirements. At the same time, when the high-speed air enters the mixing box, it can push 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, applying a downward thrust and an upward pulling force to the fixed seat, and driving the extended clamping seat to reciprocate up and down under the guiding action of the extended clamping seat and the lateral guide rail, and synchronously driving the transmission shaft to reciprocate up and down, that is, synchronously realizing the reciprocating up and down displacement of the transmission sleeve, and automatically realizing the stretching experiment inside the test box in cooperation with the stretching component.

[0025] By using the external air input during the fiberglass test to change the test environment, and cooperating with the automatic clamping of the clamping component and the automatic rising of the turntable, the automatic sealing during the test is realized. While changing the internal environment of the test box, the power transmission to the stretching component is realized by using the flowing air, thereby completing the automatic stretching experiment under the test environment, ensuring the accuracy of the test data and improving the test efficiency at the same time.

[0026] During the test, the three turntables can work together at the same time. That is, when the turntable descends to the lowest point, the turntable located at the feeding station can perform the feeding work of the fiberglass, while the turntable located at the test station is waiting for testing directly below the test box. For the turntable located at the discharging station, the test process has been completed and the clamping component no longer clamps the turntable. At this time, the fiberglass can be directly taken out to complete the discharging. And through the equal-angle rotation of the cam divider, in cooperation with the rising and falling process of the turntable, the feeding, waiting for testing, and discharging can be carried out simultaneously.

[0027] Through the cooperation between the cam divider, the cylinder and the turntable, as well as the cooperation between the stretching component, the test box and the power component, when the turntable is at the lowest point, the device can simultaneously perform the feeding, waiting for testing, and discharging processes. When the turntable is at the highest point, it can also automatically achieve the clamping and automatic stretching experiment processes. The degree of automation of the entire testing process is relatively high, significantly shortening the preparation time during batch experiments and improving the testing efficiency during batch testing.

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

[0029] 1. By setting the clamping component and the first limiting plate and cooperating with the rotation and rising process of the turntable, the present invention can automatically apply pressure to the clamping component by the first limiting plate, that is, when testing the glass fiber, the clamping process is automatically achieved, and at the same time, the clamping state is automatically released after the test. The entire process is automatically completed without manual control, so that the device does not need to be manually clamped and released during feeding and discharging, significantly shortening the loading and unloading time and improving the testing efficiency;

[0030] 2. By utilizing the external air input during the glass fiber test to change the test environment, cooperating with the automatic clamping of the clamping component, and the automatic rising of the turntable, the present invention realizes automatic sealing during the test, and while changing the internal environment of the test box, uses the flowing air to achieve power transmission to the stretching component, thereby completing the automatic stretching experiment under the test environment, ensuring the accuracy of the test data and improving the testing efficiency at the same time;

[0031] 3. Through the cooperation between the cam divider, the cylinder and the turntable, as well as the cooperation between the stretching component, the test box and the power component, when the turntable is at the lowest point, the device can simultaneously perform the feeding, waiting for testing, and discharging processes. When the turntable is at the highest point, it can also automatically achieve the clamping and automatic stretching experiment processes. The degree of automation of the entire testing process is relatively high, significantly shortening the preparation time during batch experiments and improving the testing efficiency during batch testing.

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Such as Figures 1 to 9As shown in the figure, in an embodiment of the present invention, a continuous glass fiber weather resistance test device includes a base 1. A cam divider 3 is fixedly installed at the top end of the base 1. The output end of the cam divider 3 is fixedly installed with a cylinder 4. The output end of the cylinder 4 is fixedly installed with a mounting frame 5. The outer side surface of the mounting frame 5 is axially and equidistantly installed with turntables 6. Slots 7 are provided on both sides of the top end of the turntable 6. A clamping assembly 8 is movably clamped inside the slots 7. A stretching assembly 9 is installed at the bottom end of the turntable 6. The top end of the stretching assembly 9 is connected to the clamping assembly 8. A frame 2 is fixedly installed on one side of the base 1. A test chamber 10 located directly above the turntable 6 is fixedly installed at the top end of the frame 2. A mixing chamber 14 is fixedly communicated with the middle of the top end of the test chamber 10. A three-way valve 13 is fixedly communicated with the top end of the mixing chamber 14. A first limiting plate 11 is installed in the middle of the inner side surface of the test chamber 10. Lateral guide rails 12 are installed on both the front and rear sides of the outer side surface of the test chamber 10. The middle of the mixing chamber 14 is movably connected with a main shaft 16. Power assemblies 17 are installed at both the front and rear ends of the main shaft 16 on one side of the lateral guide rails 12. The power assemblies 17 are movably clamped with the lateral guide rails 12. The single rotation angle of the cam divider 3 is 120 degrees.

[0044] During actual use, continuous glass fibers to be tested can be prepared. A section of the continuous glass fibers is taken, and the three turntables 6 are respectively corresponded to the feeding, testing, and discharging stations, and three operators work together. At the same time, an external high-speed hot air blower and a high-speed cold air blower are prepared to complete the preliminary preparation before the test.

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

[0046] Before the test, the external high-speed cold 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 in by the two can enter the inside of the three-way valve 13 and form the environmental temperature required for the test after mixing inside the mixing chamber 14.

[0047] As Figure 1 and Figure 7 and Figure 8 and Figure 9As shown, the clamping assembly 8 includes a clamping block 801, which is movably clamped with the clamping groove 7. Above the clamping block 801, there is a clamping plate 802. On both the left and right sides of the clamping plate 802, extension ear plates 803 are installed. A guide rod 804 is movably sleeved inside the extension ear plates 803. The extension ear plates 803 are displaced up and down relative to the guide rod 804. The bottom end of the guide rod 804 is connected to both sides of the top end of the clamping block 801. A limiting spring 806 is movably sleeved on the outer side of the guide rod 804. The upper and lower ends of the limiting spring 806 are respectively connected to the bottom end of the extension ear plate 803 and the top end of the clamping block 801. The top end of the guide rod 804 penetrates through the top end of the extension ear plate 803 and is fixedly connected with a second limiting plate 805. Anti-slip grooves are formed between the clamping plate 802 and the clamping block 801. In the middle of the top end of the clamping plate 802, an extension seat 807 is fixedly installed. An auxiliary wheel 808 is movably installed at the top end of the extension seat 807. When the air cylinder 4 extends to the limit position, the top end of the turntable 6 completely enters the interior of the test box 10, and the bottom end of the turntable 6 is on the same plane as the bottom end of the test box 10, and the outer side of the turntable 6 is in contact with the inner side of the test box 10. During the rising process of the turntable 6, the outer side of the auxiliary wheel 808 is in contact with the bottom end of the first limiting plate 11. When the turntable 6 rises to the highest point, the auxiliary wheel 808 approaches the clamping block 801 under the action of the first limiting plate 11, and the distance between them is reduced to the minimum value.

[0048] Embodiment: When testing glass fiber, the glass fiber to be tested can be placed between the two clamping assemblies 8 at the loading station, that is, both ends of the glass fiber are respectively placed between the two clamping blocks 801 and the clamping plates 802. 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 directly below the test box 10. At this time, the air cylinder 4 can be started to drive the mounting frame 5 and the turntable 6 to rise until the top end of the turntable 6 rises into the interior of the test box 10, and finally the bottom end of the turntable 6 is on the same plane as the bottom end of the test box 10, 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 of the auxiliary wheel 808 is in contact with the bottom end of the first limiting plate 11. As the turntable 6 continues to rise, the first limiting plate 11 can apply a downward pressure on the auxiliary wheel 808. At this time, the auxiliary wheel 808 and the extension seat 807 descend accordingly, driving the clamping plate 802 to move downward. At this time, the limiting spring 806 is compressed accordingly, driving the extension ear plate 803 to move downward relative to the clamping block 801. And the auxiliary wheel 808 can roll relative to the first limiting plate 11 when the clamping block 801 moves left and right, and always maintain contact with the first limiting plate 11. As the distance between the clamping block 801 and the clamping plate 802 is reduced, both ends of the glass fiber can be clamped between the two clamping blocks 801 and the clamping plates 802 to complete the clamping process;

[0050] When the test of the glass fiber is completed, the air cylinder 4 can be activated to control the turntable 6 to descend. At this time, the first 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 rise automatically. At this time, the distance between the clamping block 802 and the clamping block 801 increases, and no longer applies pressure to both ends of the glass fiber, automatically releasing the clamping process of the glass fiber.

[0051] By setting the clamping assembly 8 and the first limit plate 11, and cooperating with the rotation and rising process of the turntable 6, the first limit plate 11 can automatically apply pressure to the clamping assembly 8, that is, when the glass fiber is tested, the clamping process is automatically realized. At the same time, the clamping state is automatically released after the test is completed. The whole process is automatically completed without manual control, so that the device does not need to be manually clamped and released during loading and unloading, significantly shortening the loading and unloading time and improving the test efficiency.

[0052] As Figure 1 and Figure 7 and Figure 8 As shown in the figure, the stretching assembly 9 includes a movable plate 901. In the middle of the top of the movable plate 901, a telescopic rod 902 is installed. The top of the telescopic rod 902 is connected to the middle of the bottom of the turntable 6. Vertically installed at the middle of the bottom of the movable plate 901 is a transmission sleeve 906. 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. On the left and right sides of the top of the movable plate 901, first fixing seats 903 are installed. On the side of the first fixing seat 903 away from the movable plate 901, a linkage rod 905 is movably connected through a rotating shaft. On the side of the linkage rod 905 away from the first fixing seat 903, a second fixing seat 904 is movably connected through a rotating shaft. The top of the second fixing seat 904 is connected to the middle of the bottom of the clamping block 801.

[0053] In the initial state, that is, after the glass fiber is clamped, at this time the telescopic rod 902 is in the initial state, that is, at this time the movable plate 901 is at the lowest point and the transmission sleeve 906 is also at the lowest point position. 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 assembly 17, at this time the telescopic rod 902 can be shortened and drive the movable plate 901 to move upward. At this time, the two linkage rods 905 deflect accordingly, that is, the angle between the two linkage rods 905 is increased, and a thrust is applied to the two clamping blocks 801. At this time, the two clamping blocks 801 move relatively away from each other, and the glass fiber located between the two clamping blocks 801 can be stretched to complete the stretching test. By the action of the power assembly 17, the reciprocating up and down displacement of the transmission sleeve 906 can be realized, and the reciprocating stretching and contraction of the glass fiber can be realized, completing the automatic stretching experiment process.

[0054] As Figure 1and Figure 3 as well as Figure 5 As shown in Figure 5 , the power assembly 17 includes a first connecting rod 171. One end of 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 a second connecting rod 172 through a rotating shaft. The ends of the second connecting rod 172 away from the first connecting rod 171 are all movably connected to a fixed seat 173 on one side of the lateral guide rail 12 through a rotating shaft. An extended clamping seat 174 is installed at one end of the fixed seat 173 close to the lateral guide rail 12. The extended clamping seat 174 is movably clamped with the lateral guide rail 12 and is displaced up and down relative to the lateral guide rail 12. An electric push rod 175 is fixedly installed at a position on one side of the lateral guide rail 12 and close to the bottom end of the extended clamping seat 174. A transmission shaft 176 adapted to the transmission sleeve 906 is fixedly installed at the output end of the electric push rod 175. 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 is in the same plane as the bottom end of the test box 10, the middle parts of the transmission sleeve 906 and the transmission shaft 176 are on the same central axis.

[0055] Embodiment: When the bottom end of the turntable 6 is in the same plane as the bottom end of the test box 10, that is, when all the fiberglass samples enter the interior of the test box 10, the device is in the test state at this time, and at this time 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 displace, and drive the transmission shaft 176 to insert into the interior of the transmission sleeve 906, completing the clamping process with the transmission sleeve 906. At this time, the power transmission between the power assembly 17 and the stretching assembly 9 can be realized;

[0056] At the same time, by mixing an external high-speed hot air blower and a high-speed cold air blower, the mixed air can be introduced into the interior of the mixing box 14 and enter the interior of the test box 10 to change the temperature environment inside the test box 10 to meet the test requirements. At the same time, when the high-speed air enters the mixing box 14, it can push 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 exerts a downward thrust and an upward pulling force on the fixed seat 173, and drives the extended clamping seat 174 to reciprocate up and down under the guiding action of the extended clamping 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 automatically cooperates with the stretching assembly 9 to perform a stretching experiment inside the test box 10.

[0057] By using the external air input during the glass fiber test to change the test environment, cooperating with the automatic clamping of the clamping assembly 8, and the automatic rising of the turntable 6, automatic sealing during the test is achieved. While changing the internal environment of the test chamber 10, the flowing air is used to achieve power transmission to the stretching assembly 9, and then the automatic stretching experiment under the test environment is completed, ensuring the accuracy of the test data and improving the test efficiency at the same time.

[0058] During the test, the three turntables 6 can work together simultaneously. That is, when the turntable 6 descends to the lowest point, the turntable 6 located at the loading station can perform the loading work of the glass fiber, while the turntable 6 located at the test station is directly below the test chamber 10 waiting for testing. And for the turntable 6 located at the unloading station, the test process has been completed 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. And through the equal-angle rotation of the cam divider 3, cooperating with the rising and falling process of the turntable 6, the loading, waiting for testing, and unloading can be carried out simultaneously.

[0059] Through the cooperation between the cam divider 3, the cylinder 4, and the turntable 6, as well as the cooperation between the stretching assembly 9, the test chamber 10, and the power assembly 17, when the turntable 6 is at the lowest point, the device can simultaneously perform the loading, waiting for testing, and unloading processes. And when the turntable 6 is at the highest point, the clamping and the automatic stretching experiment process can also be automatically realized. The degree of automation of the entire test process is relatively high, significantly shortening the preparation time during batch experiments and improving the test efficiency during batch testing.

[0060] Working principle and usage process:

[0061] During actual use, continuous glass fibers 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 loading, testing, and unloading stations, and three operators work together. At the same time, an external high-speed hot air blower and a high-speed cold air blower are prepared to complete the preliminary preparation before the test;

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

[0063] When testing fiberglass, the fiberglass to be tested can be placed between two clamping components 8 at the loading station, that is, the two ends of the fiberglass are respectively placed between the two clamping blocks 801 and the clamping jaws 802. 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 fiberglass rotates to directly below the test chamber 10. At this time, the air cylinder 4 can be activated to drive the mounting bracket 5 and the turntable 6 to rise until the top of the turntable 6 rises into the test chamber 10, and finally the bottom end of the turntable 6 is on the same plane as the bottom end of the test chamber 10, completing the sealing process of the bottom end of the test chamber 10;

[0064] When the turntable 6 moves upward, the clamping component 8 rises accordingly until the outer side of the auxiliary wheel 808 contacts the bottom end of the first limiting plate 11. As the turntable 6 continues to rise, the first limiting plate 11 can exert a downward pressure on the auxiliary wheel 808. At this time, the auxiliary wheel 808 and the extension seat 807 descend accordingly, driving the clamping jaw 802 to move downward. At this time, the limiting spring 806 is compressed accordingly, driving the extension ear plate 803 to move downward relative to the clamping block 801. And the auxiliary wheel 808 can roll relative to the first limiting plate 11 when the clamping block 801 moves left and right, and always maintain contact with the first limiting plate 11. As the distance between the clamping block 801 and the clamping jaw 802 decreases, the two ends of the fiberglass can be clamped between the two clamping blocks 801 and the clamping jaw 802 to complete the clamping process;

[0065] When the bottom end of the turntable 6 is on the same plane as the bottom end of the test chamber 10, that is, when all the fiberglass samples enter the test chamber 10, the device is in the test state, and at this time the transmission sleeve 906 just corresponds to the transmission shaft 176. At this time, the electric push rod 175 can be activated 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. 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. At this time, 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, driving the movable plate 901 to move upward. At this time, the two linkage rods 905 deflect accordingly, that is, the included angle between the two linkage rods 905 is increased, and a thrust is applied to the two clamping blocks 801. At this time, the two clamping blocks 801 move relatively away from each other, and the glass fiber located between the two clamping blocks 801 can be stretched to complete the tensile test. Through the action of the power component 17, the reciprocating up and down displacement of the transmission sleeve 906 can be realized, and the reciprocating stretching and contraction of the glass fiber can be achieved, completing the automatic stretching experiment process;

[0067] At the same time, by mixing the external high-speed hot air blower and high-speed cold air blower, the mixed air can be introduced into the interior of the mixing box 14 and enter the interior of the test box 10 to change the temperature environment inside the test box 10 to meet the test requirements. At the same time, when the high-speed air enters the mixing box 14, it can push 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, applying a downward thrust and an upward pulling force to the fixed seat 173, and driving the extended clamping seat 174 to reciprocate up and down under the guiding action of the extended clamping seat 174 and the lateral guide rail 12, and synchronously driving the transmission shaft 176 to reciprocate up and down, that is, synchronously realizing the reciprocating up and down displacement of the transmission sleeve 906, and cooperating with the stretching component 9 to automatically carry out the stretching experiment inside the test box 10;

[0068] After the test of the glass fiber is completed, the air cylinder 4 can be activated to control the turntable 6 to descend. At this time, the first limit plate 11 no longer applies pressure to the clamping component 8. At this time, the limit spring 806 automatically resets, driving the clamping block 802 to automatically rise. At this time, the distance between the clamping block 802 and the clamping block 801 increases, and no pressure is applied to both ends of the glass fiber, automatically releasing the clamping process of the glass fiber;

[0069] During the test, the three turntables 6 can work together simultaneously. That is, when the turntable 6 descends to the lowest point, the turntable 6 located at the feeding station can carry out the feeding work of the glass fiber, while the turntable 6 located at the test station is located directly below the test box 10 waiting for testing. For the turntable 6 located at the discharging station, the test process has been completed and the clamping component 8 no longer clamps the turntable 6. At this time, the glass fiber can be directly taken out to complete the discharging. And through the equal-angle rotation of the cam divider 3, cooperating with the ascending and descending processes of the turntable 6, the feeding, waiting for testing, and discharging can be carried out simultaneously.
