Description

Technical Field

[0001] The present invention relates to the technical field of tensile strength detection, and in particular to a tensile detection device for glass fiber products, and in particular to a detection method for the tensile detection device for glass fiber products. Background Art

[0002] Finished glass fiber products include glass fiber cloth, mesh cloth and fiber tube. In order to understand the performance and life of finished glass fiber products in actual applications, they will be tested for tensile strength. The glass fiber mesh cloth is usually tested by clamping the two ends of the glass fiber mesh cloth through a clamping mechanism, and then pulling the glass fiber mesh cloth to measure the deformation of the glass fiber mesh cloth and whether it is damaged or broken, so as to ensure the quality and reliability of the product.

[0003] The Chinese patent CN117890192B discloses a tensile strength testing device for finished glass fiber products, and its working principle is as follows: first fix the base on the external workbench, then manually pass the end of the glass fiber cloth through the corresponding two pressure rods, then push the limit plate and compress the compression spring, the limit plate drives the connecting plate to rotate, and the connecting plate drives the corresponding movable rectangular block to move toward the relatively fixed rectangular block through the track groove on the shaft column, so that the corresponding two pressure rods squeeze the glass fiber cloth, then manually rotate the screw rod to screw the screw rod into the screw hole to adjust the squeezing force of the two pressure rods corresponding to the glass fiber cloth, and fix the limit plate to keep the pressure rod clamping the glass fiber cloth, and wait for After the two ends of glass fiber cloths of different lengths are connected to the corresponding pulling mechanisms, an external motor is installed on the base to drive the rotating shaft to rotate. At this time, the torque force required for the external motor to drive the vertical plate and the pulling mechanism on the vertical plate to rotate through the rotating shaft is A. Then, as the external motor rotates, the torque force changes from A to A+B, so that the pulling force on the glass fiber cloth is changed by changing the value of B, and then the deformation and damage of the glass fiber cloth under different pulling forces are observed. In addition, the distance between the T-block and the rotating shaft increases from front to back in the corresponding T-slot, so that the tensile performance of glass fiber cloths of different lengths under the same tensile force can be compared to determine whether the tensile performance of the glass fiber cloth is qualified.

[0004] The above scheme still has the following problem: when the staff clamped the two ends of the glass fiber cloth, they did not adjust the position of the glass fiber cloth. Since the direction of the force of the pulling mechanism is fixed, if the fiber filaments on the glass fiber cloth are not parallel to the direction of the force of the pulling mechanism, there will be a large deviation between the tensile performance measured by the pulling mechanism and the actual tensile performance of the glass fiber cloth.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a calibration mechanism, an adjustment mechanism and a stretching mechanism. One end of the glass fiber product passes through the first first clamping structure, the stretching mechanism and the second first clamping structure in sequence, and the two ends thereof are clamped by the two first clamping structures. The calibration laser marking line transmitter emits a straight marking line and projects it onto the glass fiber product. If the marking line intersects with the fiber filaments on the glass fiber product, the rotating adjustment structure starts to work and drives the support plate to rotate around its own central axis. Since the support plate drives the glass fiber product to rotate together through the two first clamping structures, the glass fiber product will also rotate around its central axis to adjust the direction of the fiber filaments on the glass fiber product. When a fiber filament on the glass fiber product completely coincides with the marking line, the rotating adjustment structure stops working. At this time, it can be considered that all the fiber filaments along one direction on the glass fiber product are parallel to the direction of the force applied by the stretching mechanism. The stretching mechanism starts to perform a stretching test on the glass fiber product.

The second rotating shaft drives the support plate to rotate around the axis of the second rotating shaft. The worm gear transmission structure has a self-locking ability. When the rotary driver stops working, the friction between the worm wheel and the worm will prevent them from continuing to rotate relative to each other. Therefore, no matter to which angle the support plate is rotated, once the rotary driver stops working, the support plate will immediately stop at this position and will not continue to rotate due to inertia or other external factors, thereby realizing precise rotation and stop control of the support plate and the glass fiber product on its upper end.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1 to 12 As shown: A glass fiber product stretching detection device includes a base plate 1, a calibration mechanism 2, an adjustment mechanism 3 and a stretching mechanism 4; the base plate 1 is horizontally arranged, and a plurality of supporting legs 11 are arranged at the lower end of the base plate 1, and the plurality of supporting legs 11 are used to keep the base plate 1 in a horizontal state; the calibration mechanism 2 is arranged above the base plate 1, and the calibration mechanism 2 includes a calibration laser marking line transmitter 21, and the calibration laser marking line transmitter 21 is used to emit a straight marking line to calibrate the fiber direction of the glass fiber product, and the calibration laser marking line transmitter 21 is arranged by setting a gantry 22 is mounted above the base plate 1; the adjusting mechanism 3 is arranged on the base plate 1, the adjusting mechanism 3 includes a supporting plate 31, a rotating adjusting structure 32 and two first clamping structures 33, the supporting plate 31 is arranged in parallel at the upper end of the base plate 1, the rotating adjusting structure 32 is arranged at the lower end of the supporting plate 31, the rotating adjusting structure 32 is used to drive the supporting plate 31 to rotate around its own central axis, the two first clamping structures 33 are respectively arranged at both ends of the supporting plate 31; the stretching mechanism 4 is arranged between the two first clamping structures 33, and is used for performing a tensile test on the glass fiber products.

[0033] The staff passes one end of the glass fiber product through the first first clamping structure 33, the stretching mechanism 4 and the second first clamping structure 33 in sequence, and clamps its two ends with the two first clamping structures 33, completing the preparation and fixation of the test sample. The calibrated laser marking line transmitter 21 emits a straight marking line and projects it on the glass fiber product. If the marking line intersects with the fiber filaments on the glass fiber product, it means that the direction of the fiber filaments is not parallel to the marking line, that is, there is a deviation. Then the rotating adjustment structure 32 starts to work, driving the support plate 31 to rotate around its own central axis. Since the support plate 31 passes through the two first clamping structures 33 drives the glass fiber product to rotate together, so the glass fiber product will also rotate around its central axis to adjust the direction of the fiber filaments on the glass fiber product. When a fiber filament on the glass fiber product completely coincides with the marking line, the rotation adjustment structure 32 stops working. At this time, it can be considered that all the fiber filaments along one direction on the glass fiber product are parallel to the direction of the force applied by the stretching mechanism 4. The stretching mechanism 4 starts to perform a stretching test on the glass fiber product. Since the fiber filaments are parallel to the stretching direction, the stretching force can act on the fiber filaments more directly, thereby being able to more accurately detect the tensile properties of the glass fiber product.

[0034] Reference Figure 3 , Figure 4 and Figure 5 As shown: the rotation adjustment structure 32 includes a second rotating shaft 321, a worm gear transmission structure 322 and a rotation driver 323; the second rotating shaft 321 is vertically arranged, one end of the second rotating shaft 321 is connected to the support plate 31, the other end of the second rotating shaft 321 passes downward through the base plate 1, and the second rotating shaft 321 and the base plate 1 are connected through a bearing; the worm gear transmission structure 322 is arranged at the lower end of the second rotating shaft 321, the worm wheel is connected to the second rotating shaft 321, and the worm is connected to the rotation driver 323; the rotation driver 323 is connected to the worm gear transmission structure 322.

[0035] The marking line emitted by the calibration laser marking line transmitter 21 is projected onto different glass fiber products. The angles between the marking line and the fiber filaments on different glass fiber products are different. Therefore, the support plate 31 needs to be able to rotate to different angles to ensure that the fiber filaments are parallel to the marking line. By setting the second rotating shaft 321, the worm gear transmission structure 322 and the rotation driver 323, the rotation driver 323 drives the worm to rotate, and the worm drives the worm wheel to rotate, thereby driving the second rotating shaft 321 connected to the worm wheel to rotate, and the second rotating shaft 321 drives the support plate 31 to rotate around the axis of the second rotating shaft 321. The worm gear transmission structure 322 has a self-locking ability. When the rotation driver 323 stops working, the friction between the worm wheel and the worm will prevent them from continuing to rotate relative to each other. Therefore, no matter to which angle the support plate 31 is rotated, once the rotation driver 323 stops working, the support plate 31 will immediately stop at this position, and will not continue to rotate due to inertia or other external factors, thereby achieving precise rotation and stop control of the support plate 31 and the glass fiber product on its upper end.

[0036] Reference Figure 3 , Figure 4 and Figure 6As shown, the first clamping structure 33 includes a mounting seat 331, a guide roller group 332, a pressing roller group 333 and a pressing assembly 334; the mounting seat 331 is arranged on the support plate 31; the guide roller group 332 is arranged on the mounting seat 331, and the guide roller group 332 has n rollers; the pressing roller group 333 is arranged in parallel at the upper end of the guide roller group 332, and the pressing roller group 333 has n-1 rollers. The rollers in the guide roller group 332 are arranged alternately; the pressing assembly 334 is arranged at the upper end of the pressing roller group 333, and the pressing assembly 334 is used to apply a downward force to the pressing roller group 333. The pressing assembly 334 includes a first U-shaped plate 3341, a lower pressing plate 3342, two second guide columns 3343, two first springs 3344, a bolt 3345 and a screw sleeve 3346. The two ends of the first U-shaped plate 3341 The two ends of the second guide column 3343 are respectively connected to the two ends of the mounting seat 331, the lower pressure plate 3342 is arranged inside the first U-shaped plate 3341, the lower pressure plate 3342 is connected to the clamping roller group 333, the two second guide columns 3343 are respectively arranged at the two ends of the lower pressure plate 3342, one end of the second guide column 3343 is connected to the lower pressure plate 3342, and the other end of the second guide column 3343 passes through the first U-shaped plate 3341 upward, the two first springs 3344 are respectively sleeved on the two second guide columns 3343, the two ends of the first spring 3344 are respectively abutted against the end of the second guide column 3343 and the first U-shaped plate 3341, one end of the bolt 3345 passes through the first U-shaped plate 3341 from top to bottom and abuts against the lower pressure plate 3342, the screw sleeve 3346 is sleeved on the bolt 3345, the screw sleeve 3346 is transmission connected to the bolt 3345, and the screw sleeve 3346 is fixedly connected to the first U-shaped plate 3341.

[0037] When the staff passes the glass fiber product through the first first clamping structure 33, the lower surface of the glass fiber product contacts the guide roller set 332. When the staff pulls the glass fiber product to move, rolling friction occurs between the glass fiber product and the guide roller set 332 to prevent the surface of the glass fiber product from being scratched. After one end of the glass fiber product passes through the second first clamping structure 33, the staff first operates the second first clamping structure 33 to clamp one end of the glass fiber product, and then operates the first first clamping structure 33 to clamp the other end of the glass fiber product. The staff rotates the bolt 3345, and the bolt 3345 is in The screw sleeve 3346 moves toward the guide roller group 332, the bolt 3345 applies a downward force to the lower pressure plate 3342, and the lower pressure plate 3342 pushes the clamping roller group 333 to move toward the guide roller. The clamping roller group 333 and the guide roller group 332 are arranged alternately. When a downward force is applied to the clamping roller group 333 by the lower pressure assembly 334, the two work together to clamp the fiberglass product to form a wavy shape, thereby increasing the contact area between the product and the roller, and improving the uniformity and stability of the clamping force, thereby effectively preventing the fiberglass product from being displaced during the adjustment process.

[0038] Reference Figure 3 , Figure 4 and Figure 7 As shown: the adjustment mechanism 3 also includes a tensioning structure 34, which is arranged inside the support plate 31. The tensioning structure 34 is used to drive the two first clamping structures 33 to move closer to or away from each other. The tensioning structure 34 includes a first guide cross bar 341, two first sliders 342, two second springs 343, a second linear driver 344 and two first driving plates 345. The two ends of the first guide cross bar 341 are respectively connected to the two ends of the support plate 31, the two first sliders 342 are both slidably arranged on the first guide cross bar 341, and the two first sliders 342 are respectively connected to the two mounting seats 331, the two second springs 343 are respectively sleeved on the two ends of the first guide cross bar 341, and the two ends of the second spring 343 are respectively abutted against the first slider 342 and the end of the support plate 31, the second linear driver 344 is arranged in the middle of the support plate 31, and the two first driving plates 345 are respectively arranged on both sides of the second linear driver 344, and the two ends of the first driving plate 345 are respectively hinged to the first slider 342 and the second linear driver 344.

[0039] The two first clamping structures 33 clamp the two ends of the glass fiber product. As the glass fiber product falls due to gravity, the length of the glass fiber product will be greater than the distance between the two first clamping structures 33. The glass fiber product in a bent state will shake when subjected to a slight external force. Therefore, it is difficult to determine whether the marking line emitted by the calibration laser marking line transmitter 21 coincides with the fiber filaments in the glass fiber product. By setting the tensioning structure 34, the second linear driver 344 applies a thrust to the two first driving plates 345, and the first driving plates 345 transmit the thrust to the first slider 342. The force applied to the first slider 342 will decompose into a component force along the axial direction of the first guide cross bar 341. The component force pushes the first slider 342 to move along the first guide cross bar 341, and the two first sliders 342 move away from each other. The two first sliders 342 drive the two first clamping structures 33 to move away from each other. The two first clamping structures 33 tighten the glass fiber product, so the glass fiber product is difficult to shake, thereby facilitating the observation of the position state between the marking line and the fiber filaments on the glass fiber product.

[0040] Reference Figure 3 and Figure 8 As shown, the calibration mechanism 2 further includes a visual monitor 23 . There are two visual monitors 23 . The two visual monitors 23 are respectively arranged on both sides of the calibration laser marking line transmitter 21 , and the connection line between the two visual monitors 23 extends to both ends of the support plate 31 .

[0041] If the position status between the marking line and the fiber filaments on the glass fiber product is observed by the staff, it is easily affected by various factors such as the staff's viewing angle, lighting conditions, and fatigue level, resulting in subjectivity and uncertainty in the judgment result. By setting two visual monitors 23, the visual monitors 23 are located directly above the marking line and can monitor both ends of the marking line at the same time, so that the visual monitors 23 can more accurately determine whether the marking line and the fiber filaments coincide with each other, thereby achieving more accurate and objective monitoring of the position status between the marking line and the fiber filaments, and improving the accuracy and efficiency of calibration.

[0042] Reference Figure 3 , Fig. 9 and Fig.10As shown: the calibration mechanism 2 also includes a transmitter adjustment structure 24, which is arranged at the upper end of the calibration laser marking line transmitter 21, and the transmitter adjustment structure 24 includes a first rectangular frame 241, a first rotating shaft 242 and a swinging assembly 243; the first rectangular frame 241 is arranged parallel to the bottom plate 1; the two ends of the first rotating shaft 242 are respectively axially connected to the two ends of the first rectangular frame 241, and the axis of the first rotating shaft 242 is parallel to the connecting line of the two visual monitors 23, the calibration laser marking line transmitter 21 is hoisted at the lower end of the first rotating shaft 242, and the calibration laser marking line transmitter 21 rotates synchronously with the first rotating shaft 242; the swinging assembly 243 is arranged at the upper end of the first rotating shaft 242, and the swinging assembly 243 is used to drive the first rotating shaft 242 to rotate.

[0043] The intersection of the marking line and the fiber filament may not coincide with the axis of the second rotating shaft 321. The standard fiber filament will deviate from one side of the marking line when rotating, which makes it difficult to determine whether the fiber filament has rotated to the position that is most conducive to detection. By setting the transmitter adjustment structure 24, the adjustment mechanism 3 first rotates the standard fiber filament to one side of the marking line. Since it is impossible to determine whether the standard fiber filament is parallel to the marking line, the swing assembly 243 drives the first rotating shaft 242 to rotate, and the first rotating shaft 242 drives the calibration laser marking line transmitter 21 to translate toward one side. If the marking line still has only one intersection with the fiber filament after translation, the adjustment mechanism 3 adjusts the position of the glass fiber product as needed, and the swing assembly 243 drives the marking line to translate as needed until the marking line and the fiber filament completely coincide with each other, thereby achieving precise adjustment of the calibration laser marking line transmitter 21, so that the fiber filament can be adjusted to the optimal position.

[0044] Reference Fig. 9 and Fig.10 As shown: the swing assembly 243 includes a transmission plate 2431, a driving shaft 2432 and a first linear driver 2433; one end of the transmission plate 2431 is fixedly connected to the middle of the first rotating shaft 242, and the other end of the transmission plate 2431 is provided with a limiting slide groove; the driving shaft 2432 is arranged in the limiting slide groove; the first linear driver 2433 is installed on the first rectangular frame 241, and the output end of the first linear driver 2433 is connected to the driving shaft 2432.

[0045] The first linear drive 2433 pushes the driving shaft 2432 to move horizontally in the limiting slide groove. Since one end of the transmission plate 2431 is fixedly connected to the first rotating shaft 242, and the other end is connected to the driving shaft 2432 through the limiting slide groove, the horizontal movement of the driving shaft 2432 will be converted into the rotation of the transmission plate 2431 around the first rotating shaft 242. The driving shaft 2432 can move to different positions inside the limiting slide groove, and each position corresponds to a specific rotation angle of the first rotating shaft 242, so that the angle adjustment has good flexibility, so that the system can adjust the calibration laser marking line transmitter 21 to any desired angle position as needed, thereby realizing precise angle adjustment of the calibration laser marking line transmitter 21.

[0046] Reference Fig. 9 and Fig.10 As shown: the swing assembly 243 also includes a second rectangular frame 2434 and two first guide pillars 2435; the second rectangular frame 2434 is covered on the outside of the transmission plate 2431, and both ends of the driving shaft 2432 are connected to the second rectangular frame 2434; the two first guide pillars 2435 are respectively set at both ends of the second rectangular frame 2434, one end of the first guide pillar 2435 is connected to the second rectangular frame 2434, and the other end of the first guide pillar 2435 is slidably connected to the first rectangular frame 241.
