Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically a tear strength testing machine for radiation-proof peach skin yarn-dyed fabric. Background Technology

[0002] Peach skin velvet yarn-dyed fabric is a type of imitation leather fabric with certain radiation protection functions. During the fabric production process, tear strength testing is required. This is done by clamping both ends of the fabric and then moving them apart to test for tearing. For example, a fabric tear strength testing device with announcement number CN205426687U includes a base, on which a fabric clamping device, a fabric tearing device, and a fabric tear force transmission device are mounted. The fabric clamping device includes two parallel fixed seats forming a tear seam between them. A moving block is mounted on each fixed seat. The fixed seats are U-shaped, and the fixed seats and moving blocks form a fabric clamping groove. An adjusting screw is connected to the moving block and is located inside the base. The tear force is transmitted to a display screen via a transmitter to accurately read the fabric tear force. However, this tear strength testing device still has the following drawbacks in actual use:

[0003] Traditional testing machines mostly rely solely on stretching the fabric during testing, resulting in a limited testing method. Furthermore, fabrics are susceptible to various forms of tearing during use, leading to inaccurate test results. To address these issues, there is an urgent need for innovative designs based on existing tear strength testing machines. Utility Model Content

[0004] The purpose of this utility model is to provide a tear strength testing machine for radiation-proof peach skin yarn-dyed fabric, so as to solve the problem that the traditional testing machines mentioned in the background technology mostly rely on pulling the fabric during the testing process, so the testing method is relatively simple. Furthermore, the fabric is easily subjected to different forms of tearing during use, resulting in inaccurate test results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tear strength testing machine for radiation-proof peach skin velvet yarn-dyed fabric, comprising a test platform, an electric motor mounted on the side of the test platform by bolts, and a lead screw connected to the output shaft of the electric motor, two threaded grooves symmetrically arranged on the lead screw, and the lead screw and the bottom of the support plate being threadedly connected, a through groove being opened on the test platform on the outer side of the support plate, and the support plate and the test platform forming a sliding structure through the through groove;

[0006] It also includes: a connecting plate, which is disposed above the support plate. A collar is fixed to the top of the connecting plate, and a base passes through the inside of the collar. An adjusting rod is rotatably disposed on the upper end face of the base, and a clamping plate is threaded on the outer side of the adjusting rod. A guiding mechanism is disposed at the end of the base, and the guiding mechanism is used to guide the base to rotate.

[0007] Preferably, the inner wall of the through groove is provided with fixing blocks at equal intervals, and the fixing blocks are in close contact with the side of the support plate. When the support plate moves, it generates vibration through contact with the fixing blocks.

[0008] Preferably, the top of the support plate is connected to the connecting plate via a connecting block, and the connecting block is made of rubber. When vibration occurs, the vibration force can be transmitted to the connecting plate through the setting of the connecting block.

[0009] Preferably, the base and the collar form a rotating structure, and the upper end face of the base and the lower end face of the clamp are both serrated. The side of the clamp and the inner side of the base slide together, and the adjusting rod can be driven to rise and fall through the threaded transmission with the clamp.

[0010] Preferably, the guiding mechanism includes a fixed rod fixed to the base, and the end of the fixed rod away from the base is connected to the fixed cylinder. When the base moves, it drives the fixed rod to move synchronously and extends into the fixed cylinder.

[0011] Preferably, the fixing cylinder is fixed above both ends of the test bench, and the inner wall of the fixing cylinder is provided with a guide groove. The fixing rod has an "L" shaped structure. When the fixing rod moves, it contacts the guide groove in the fixing bench, so that the fixing rod can be guided to rotate.

[0012] Preferably, the vertical end of the fixing rod is slidably connected to the guide groove, and the guide groove has a spiral structure. The guide grooves in the two fixing cylinders are in opposite directions, and the base rotates synchronously when the fixing rod rotates.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the tear strength testing machine for the radiation-proof peach skin yarn-dyed fabric can add the method of rotating the fabric and vibrating it during the bidirectional tensile process, thereby increasing the diversity of the test and improving the accuracy of the tear test results. The specific details are as follows:

[0014] 1. When the support plate moves in the through groove, it can contact the fixed block. Since the connecting block is made of rubber, the vibration generated by the contact is transmitted to the connecting plate through the connecting block. In this way, when the tear test is carried out by horizontal movement, the diversity of the test can be improved by vibration.

[0015] 2. When the two bases move away from each other, they drive the two fixed rods to move away synchronously, and the fixed rods can contact the inner wall of the fixed cylinder. The fixed rods can rotate when they move through the guide groove, which in turn drives the bases to rotate synchronously. In this way, when testing the fabric, the fabric can be twisted to achieve different testing methods. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution:

[0025] To address the problems existing in the prior art, this embodiment provides the following technical solution: a tear strength testing machine for radiation-proof peach skin velvet woven fabric, comprising a test bench 1, a motor 2 bolted to the side of the test bench 1, and a lead screw 3 connected to the output shaft of the motor 2, two symmetrically arranged threaded grooves on the lead screw 3, and the lead screw 3 and the bottom of the support plate 4 being threadedly connected, a through groove 5 opened on the test bench 1 outside the support plate 4, and the support plate 4 and the test bench 1 forming a sliding structure through the through groove 5; further comprising: a connecting plate 8, disposed above the support plate 4, a collar 12 fixed to the top of the connecting plate 8, and a base 9 penetrating through the inside of the collar 12, an adjusting rod 10 rotatably disposed on the upper end face of the base 9, and a clamping plate 11 threadedly sleeved on the outer side of the adjusting rod 10, and a guiding mechanism disposed at the end of the base 9, the guiding mechanism being used to guide the rotation of the base 9.

[0026] Existing testing machines mostly rely solely on stretching the fabric during testing, resulting in a limited testing method. Fabrics are susceptible to various forms of tearing during use, leading to inaccurate test results. The inner wall of the through-slot 5 is equipped with evenly spaced fixing blocks 6, which are in close contact with the side of the support plate 4. The top of the support plate 4 is connected to the connecting plate 8 via a connecting block 7, which is made of rubber. The base 9 and the collar 12 form a rotating structure, with the upper surface of the base 9 and the lower surface of the clamping plate 11 both being serrated. The side of the clamping plate 11 slides against the inner side of the base 9. First, the edge of the fabric to be tested is placed on the base 9. The rotating adjusting rod 10 drives the clamping plate 11 to descend through the threaded transmission with the clamping plate 11. When the clamping plate 11 descends to fit against the base 9, the fabric can be clamped. Then, the motor 2 drives the lead screw 3 to rotate. Through the threaded transmission between the lead screw 3 and the support plate 4, the two support plates 4 are driven away from each other, which in turn drives the base 9 and the clamping plate 11 to move away from each other to achieve the tear test of the fabric. When the support plate 4 moves, it can slide in the through groove 5 and contact the fixed block 6. The vibration generated by the contact between the two is transmitted to the connecting plate 8 through the connecting block 7. In this way, when the tear test is carried out in a horizontal movement, the diversity of the test can be improved by vibration, thereby improving the accuracy of the test results.

[0027] The guiding mechanism includes a fixed rod 13 fixed to the base 9, and the end of the fixed rod 13 away from the base 9 is connected to a fixed cylinder 14. The fixed cylinder 14 is fixed above both ends of the test bench 1, and the inner wall of the fixed cylinder 14 is provided with a guide groove 15. The fixed rod 13 has an "L" shaped structure. The vertical end of the fixed rod 13 is slidably connected to the guide groove 15, and the guide groove 15 has a spiral structure. The directions of the guide grooves 15 in the two fixed cylinders 14 are opposite. When the two bases 9 move away from each other, the two fixed rods 13 move away synchronously. When the fixed rod 13 moves, it can contact the inner wall of the fixed cylinder 14. Through the guidance of the guide groove 15, the fixed rod 13 can rotate when it moves, thereby driving the base 9 to rotate synchronously. In this way, when testing the fabric, it can not only be tested by pulling, but also by twisting the fabric to achieve different testing methods. Since the directions of the guide grooves 15 in the two fixed cylinders 14 are opposite, the directions of rotation of the two ends of the fabric are also different.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
