Description

Technical Field

[0001] This utility model relates to the field of glass fiber mesh testing technology, and more specifically, to a glass fiber mesh strength testing device. Background Technology

[0002] Fiberglass mesh is a common building material, mainly used to enhance the strength and stability of walls, floors and other surfaces. It has excellent tensile strength, corrosion resistance and high temperature resistance, and is widely used in many fields such as construction, decoration and road construction.

[0003] According to a patent publication number CN117110060B, a method for testing the tensile strength of alkali-resistant glass fiber mesh fabric includes the following steps: sampling, gluing a reinforcing sheet, and testing. A horizontal moving mechanism is provided on one side of the gluing device and clamping device. The gluing device includes a height adjustment mechanism and a clamping mechanism, and the clamping device includes a stretching mechanism and a clamping mechanism. In this method, a double-headed bidirectional screw is driven by another drive motor within the processing table, causing relative movement of the opposing clamping plates. The toothed surface of the clamping plates clamps the rough, toothed outer surface of the reinforcing sheet. Through the action of the pulley and transmission belt, the two opposing unidirectional screws and the double-headed bidirectional screw rotate synchronously, allowing the upper and lower ends of the clamping plates to advance simultaneously, thus clamping the sample fabric and preventing slippage during stretching. This invention, by only conducting tensile strength tests, cannot fully reflect the comprehensive performance of alkali-resistant glass fiber mesh. In practical applications, the mesh also needs to possess multiple properties such as good alkali resistance, fatigue resistance, heat resistance, and aging resistance. Existing testing methods fail to cover these important indicators, which may lead to problems in actual use.

[0004] Therefore, it is necessary to design a glass fiber mesh strength testing device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a glass fiber mesh strength testing device.

[0006] The technical solution is as follows: A glass fiber mesh strength testing device includes a support frame, a tensile strength mechanism, a displacement mechanism, and an impact strength mechanism. The support frame is equipped with the tensile strength mechanism, and the displacement mechanism is located behind the support frame. The displacement mechanism is equipped with the impact strength mechanism. The impact strength mechanism includes a cylinder, a connecting frame, a second electric push rod, and a gravity block. The cylinder is mounted on the displacement mechanism, and the connecting frame is connected to the telescopic end of the cylinder. A feeding port is opened on the part of the connecting frame near the middle of the support frame. The second electric push rod is mounted on the telescopic end of the cylinder, and the telescopic end of the second electric push rod is slidably connected to the connecting frame. A gravity block is placed in the middle of the connecting frame.

[0007] Optionally, at least six gravity blocks are provided.

[0008] Optionally, it also includes a collection frame and a cushioning pad, with the collection frame connected to the middle of the support frame and the cushioning pad connected to the inner bottom surface of the collection frame.

[0009] Optionally, the tensile strength mechanism includes a guide plate, a first sliding plate, a connecting plate, a second sliding plate, a lifting plate, a first electric push rod, and an electric slide rail.

A first electric push rod is symmetrically installed on the support frame, and a lifting plate is connected to the telescopic end of each first electric push rod. The second sliding plates are slidably connected to the lifting plates, and the second sliding plates are located between the lifting plates.

[0010] Optionally, the displacement mechanism includes a fixed frame and a first sliding block. The fixed frame is located behind the support frame, and the first sliding block is slidably connected to the fixed frame. A cylinder is mounted on the first sliding block.

[0011] Optionally, it also includes a second sliding block and a return spring. The second sliding block is slidably connected inside the connecting frame. The initial position of the second sliding block is located on the side of the feed port closer to the gravity block. A return spring is connected between the second sliding block and the connecting frame. The initial state of the return spring is a compressed state.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] Example: A glass fiber mesh strength testing device, such as... Figures 1-6 As shown, the device includes a support frame 1, a tensile strength mechanism, a displacement mechanism, and an impact strength mechanism. The support frame 1 is equipped with the tensile strength mechanism, and a displacement mechanism is located behind the support frame 1. The displacement mechanism is equipped with the impact strength mechanism. The impact strength mechanism includes a cylinder 12, a connecting frame 13, a second electric push rod 14, and gravity blocks 17. The cylinder 12 is mounted on the displacement mechanism, and the connecting frame 13 is welded to the telescopic end of the cylinder 12. A discharge port is opened on the part of the connecting frame 13 near the middle of the support frame 1. The second electric push rod 14 is bolted to the telescopic end of the cylinder 12. The telescopic end of the second electric push rod 14 is slidably connected to the connecting frame 13. At least six gravity blocks 17 are placed in the middle of the connecting frame 13 to enhance the test strength. The second electric push rod 14 pushes the gravity blocks 17 forward with its telescopic end. When the gravity blocks 17 are aligned with the discharge port on the connecting frame 13, the gravity blocks 17 will fall quickly onto the glass fiber mesh sample due to their own weight.

[0023] like Figure 2 and Figure 3As shown, it also includes a collection frame 8 and a buffer pad 9. The collection frame 8 is connected to the middle of the support frame 1, and the buffer pad 9 is connected to the inner bottom surface of the collection frame 8. The broken sample will fall into the collection frame 8 for easy subsequent unified processing. The buffer pad 9 can effectively reduce the impact on the equipment when the sample breaks, while protecting the sample part that is not completely broken.

[0024] like Figures 1-4 As shown, the tensile strength mechanism includes a guide plate 2, a first sliding plate 3, a connecting plate 31, a second sliding plate 4, a lifting plate 5, a first electric push rod 6, and an electric slide rail 7. Guide plates 2 are symmetrically connected to the support frame 1 from left to right. Electric slide rails 7 are symmetrically installed on each guide plate 2 via fixing components. A first sliding plate 3 is slidably connected to the electric slide rail 7 on the same side. A connecting plate 31 is symmetrically connected to each first sliding plate 3 from front to back. A second sliding plate 4 is slidably connected to the connecting plate 31 on the same side. A first electric push rod 6 is symmetrically installed on the support frame 1 from front to back via connecting components. A lifting plate 5 is connected to the telescopic end of each first electric push rod 6. The second sliding plates 4 are slidably connected to the lifting plates 5 from top to bottom, and the second sliding plates 4 are located between the lifting plates 5. The electric slide rail 7 is activated, allowing it to carry the clamped sample's first sliding plate 3 and second sliding plate 4 in opposite directions, thereby stretching the glass fiber mesh sample until it breaks. The maximum load value at sample breakage is recorded to evaluate its maximum load-bearing capacity under tensile force.

[0025] like Figure 2 and Figure 5 As shown, the displacement mechanism includes a fixed frame 10 and a first sliding block 11. The fixed frame 10 is provided behind the support frame 1, and the first sliding block 11 is slidably connected to the fixed frame 10. The cylinder 12 is installed on the first sliding block 11.

[0026] like Figure 5 and Figure 6 As shown, it also includes a second sliding block 15 and a return spring 16. The second sliding block 15 is slidably connected to the inside of the connecting frame 13. The initial position of the second sliding block 15 is located on the side of the feed port near the gravity block 17. The second sliding block 15 and the connecting frame 13 are connected by a spring seat and the return spring 16. The initial state of the return spring 16 is the compressed state.

[0027] When using this device, first adjust the distance between the two first sliding plates 3 according to the length of the fiberglass mesh sample to be tested. Then, activate the electric slide rail 7 to move the first sliding plates 3 to the desired position, and then stop the operation of the electric slide rail 7. Next, place the fiberglass mesh sample to be tested on the first sliding plate 3, activate the first electric push rod 6 to cause the lifting plate 5 to descend along the connecting plate 31, thereby driving the second sliding plate 4 to approach the first sliding plate 3 until the second sliding plate 4 contacts the fiberglass mesh and continues to descend to ensure it is firmly clamped. Then, reactivate the electric slide rail 7 to move the clamped first sliding plate 3 and the second sliding plate 4 in opposite directions, thus stretching the fiberglass mesh sample until it breaks. Record the maximum load value when the sample breaks to assess its maximum load-bearing capacity under tension. The broken sample will fall into the collection frame 8 for subsequent unified processing. The buffer pad 9 effectively reduces the impact on the equipment when the sample breaks, while protecting the partially broken sample portion. If further processing of the fiberglass mesh sample is required... To conduct an impact strength test, another sample from the same batch as before is selected and fixed according to the above steps. Then, cylinder 12 is activated, raising the collection frame 8 to a predetermined height. The second electric push rod 14 is then operated, pushing the gravity block 17 forward with its extension end. This causes the second sliding block 15 to move forward with the gravity block 17, and the return spring 16 is compressed accordingly. When the gravity block 17 aligns with the discharge port on the connecting frame 13, the gravity block 17 will fall rapidly onto the fiberglass mesh sample due to its own weight. The second electric push rod 14 continues to move forward, adjusting the position of the second sliding block 15, thereby changing the horizontal position of the falling gravity block 17. This simulates the scenario of falling objects or external force impacts that the fiberglass mesh sample may encounter in actual applications, evaluating its impact resistance and durability in the face of sudden impacts. Therefore, this device has the ability to conduct tensile strength and impact strength tests, and can evaluate the performance of the fiberglass mesh sample from multiple perspectives, improving the comprehensiveness and accuracy of the test, and fully meeting the high standards required by modern industry for material performance testing.
