Description

Technical Field

[0001] This utility model relates to the field of tape testing technology, and in particular to a tensile testing device for tape production testing. Background Technology

[0002] As a common industrial product, tape is widely used in packaging, electronics, automobiles, medical and other fields. The quality of tape directly affects its performance and safety. Therefore, it is essential to conduct strict testing on tape during the production process. Tensile properties are one of the key indicators for tape quality testing, reflecting the deformation and fracture characteristics of tape under stress.

[0003] Traditional clamping devices typically employ simple jaw or clamp structures, which are ill-suited for tapes of varying widths and thicknesses. During the stretching process, uneven clamping force or insufficient clamping area can cause the tape to slip or detach, leading to inaccurate test results. Therefore, those skilled in the art have developed a tensile testing device for tape production inspection to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tensile testing device for tape production testing. The clamping device, through a third threaded rod and a moving plate, can adapt to tapes of different widths and thicknesses. At the same time, the teeth and grooves effectively prevent the tape from slipping or falling off during the stretching process, ensuring the accuracy of the test results.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tensile testing device for tape production testing, comprising a base, a rectangular groove at the center of the upper end face of the base, a rotary motor at the center of one side face of the base, the output end of the rotary motor passing through one side face of the base and extending into the rectangular groove, and a first threaded rod fixedly connected to the other end of the rotary motor, a second threaded rod fixedly connected to the other end of the first threaded rod, a clamping device sleeved on the outer side of the first threaded rod and the second threaded rod near the center connection, and a limiting device at the center of the front end face of each of the two clamping devices; Taking the clamping device located on one side as an example, the clamping device includes a movable seat, which is sleeved on the outer center of the first threaded rod on the other side. A third threaded rod is rotatably connected to the center of the upper end face of the movable seat via a bearing. A movable plate is threadedly sleeved on the outer center of the third threaded rod. Square grooves are provided on both sides of the rear end of the center of the upper end face of the movable seat. Square blocks are provided on both sides of the rear end of the center of the lower end face of the movable plate. Multiple teeth are arranged longitudinally on the center of the lower end face of the movable plate. Multiple tooth grooves are arranged longitudinally on the center of the upper end face of the movable seat. The above technical solution involves placing the tape on two movable seats, then rotating two third threaded rods to move the movable plate downwards to clamp the tape. The square block at the lower end of the movable plate engages with the square groove at the upper end of the movable seat, restricting the rotation of the movable plate and allowing it to move only axially. The teeth at the lower end of the movable plate mesh with the toothed groove at the upper end of the movable seat, increasing the contact area with the tape and thus improving the clamping force. The clamping device, through the third threaded rods and the movable plate, can adapt to tapes of different widths and thicknesses. At the same time, the teeth and toothed grooves effectively prevent the tape from slipping or falling off during the stretching process, ensuring the accuracy of the test results.

[0006] Furthermore, taking the limiting device at one side as an example, the limiting device includes a rotating frame, the rotating frame is located at the center of the front end face of the moving plate, three rubber strips are arranged vertically at the center of the two inner side walls of the rotating frame, three circular grooves are arranged vertically at the center of the front end face of the moving seat, springs are provided inside the three circular grooves, and trapezoidal blocks are provided at the center of the front end face of the three springs. The above technical solution involves rotating the rotating frame 90 degrees, then moving the plate down to press the clamping device to hold the tape, and then rotating the rotating frame back to its original position. During the rotation of the rotating frame, the trapezoidal block is squeezed, causing the spring to be compressed. After the rotating frame returns to its original position, the spring rebounds, causing the trapezoidal block to pop out inside the three rubber strips. The limiting device prevents the clamping device from loosening or shifting during the stretching process, ensuring that the tape is always in a stable clamping state during the test. At the same time, the clamping force of the two clamping devices is precisely adjusted.

[0007] Furthermore, a groove is provided at the rear center of the upper end surface of the base, and a measuring ruler is provided inside the groove; Through the above technical solution, the measuring ruler helps operators to understand the stretching of the tape in a timely manner, ensuring the smooth progress of the testing process.

[0008] Furthermore, a pointing seat is provided at the center of the rear end face of the movable seat; The above technical solution allows workers to more easily observe key parameters such as the break point of the tape using the pointing base.

[0009] Furthermore, the threads of the first threaded rod and the second threaded rod are reversed; By employing the above technical solution, the threads of the first threaded rod and the second threaded rod are set in opposite directions, so that when the first threaded rod and the second threaded rod rotate, the clamping device moves in opposite directions.

[0010] Furthermore, the three square blocks are correspondingly arranged with respect to the three square slots; The above technical solution uses a square block and a square slot to correspond and limit the movement of the moving plate when the third threaded rod rotates and drives the moving plate to descend, thus preventing the moving plate from rotating.

[0011] Furthermore, a rotating seat is provided at the center of the upper end face of the third threaded rod; The above technical solution allows workers to better manually control the rotation of the third threaded rod by using a rotating seat.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the clamping device of the tensile testing device for tape production testing can adapt to tapes of different widths and thicknesses through the third threaded rod and the moving plate. At the same time, the teeth and grooves effectively prevent the tape from sliding or falling off during the stretching process, ensuring the accuracy of the test results.

[0013] 2. In this utility model, the limiting device prevents the clamping device from loosening or shifting during the stretching process, ensuring that the tape is always in a stable clamping state during the test, while also precisely adjusting the clamping force of the two clamping devices.

[0016] 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.

[0017] Reference Figure 1-4 An embodiment of this utility model provides a tensile testing device for tape production testing, including a base 1, a rectangular groove 2 at the center of the upper surface of the base 1, a rotary motor 3 at the center of one side of the base 1, the output end of the rotary motor 3 passing through one side of the base 1 and extending into the rectangular groove 2, and the other end being fixedly connected to a first threaded rod 4, the other end of the first threaded rod 4 being fixedly connected to a second threaded rod 5, and clamping devices 6 being sleeved on the outer sides of the first threaded rod 4 and the second threaded rod 5 near the center connection, and limiting devices 7 being provided at the center of the front end face of the two clamping devices 6.

[0018] like Figure 2 As shown, taking the clamping device 6 on one side as an example, the clamping device 6 includes a movable seat 601, which is sleeved on the outer center of the first threaded rod 4 on the other side. A third threaded rod 602 is rotatably connected to the center of the upper end face of the movable seat 601 via a bearing. A movable plate 603 is threadedly sleeved on the outer center of the third threaded rod 602. Square grooves 605 are provided on both sides of the rear end of the upper end face of the movable seat 601. Square blocks 606 are provided on both sides of the rear end of the lower end face of the movable plate 603. Multiple teeth 607 are arranged longitudinally on the front side of the lower end face of the movable plate 603. Multiple toothed grooves 608 are arranged longitudinally on the front side of the upper end face of the movable seat 601. The tape is placed on both sides... On the movable seat 601, the two third threaded rods 602 are rotated to move the movable plate 603 downward to clamp the tape. The square block 606 at the lower end of the movable plate 603 cooperates with the square groove 605 at the upper end of the movable seat 601 to restrict the rotation of the movable plate 603, so that it can only move axially. The teeth 607 at the lower end of the movable plate 603 mesh with the toothed groove 608 at the upper end of the movable seat 601 to increase the contact area with the tape, thereby improving the clamping force. The clamping device 6 can adapt to tapes of different widths and thicknesses through the third threaded rods 602 and the movable plate 603. At the same time, the teeth 607 and toothed groove 608 effectively prevent the tape from slipping or falling off during the stretching process, ensuring the accuracy of the test results.

[0019] like Figure 2 and 3As shown, taking the limiting device 7 on one side as an example, the limiting device 7 includes a rotating frame 701, which is located at the center of the front end face of the moving plate 603. Three rubber strips 702 are arranged vertically at the center of the two inner side walls of the rotating frame 701. Three circular grooves 703 are arranged vertically at the center of the front end face of the moving plate 601. Each of the three circular grooves 703 contains a spring 704, and each of the three springs 704 has a trapezoidal block 705 at the center of its front end face. Rotating the rotating frame 701 90 degrees, and then the moving plate 603... The pressing clamping device 6 clamps the tape, and then the rotating frame 701 is rotated back to its original position. During the rotation of the rotating frame 701, the trapezoidal block 705 is squeezed, which compresses the spring 704. After the rotating frame 701 returns to its original position, the spring 704 rebounds, causing the trapezoidal block 705 to pop out inside the three rubber strips 702. The limiting device 7 prevents the clamping device 6 from loosening or shifting during the stretching process, ensuring that the tape is always in a stable clamping state during the test. At the same time, the clamping force of the two clamping devices 6 is precisely adjusted.

[0020] A groove 8 is provided at the rear center of the upper surface of the base 1. A measuring ruler 9 is provided inside the groove 8. The measuring ruler 9 helps the operator to understand the stretching of the tape in a timely manner and ensures the smooth progress of the test process.

[0021] A guide seat 609 is provided at the center of the rear end face of the movable seat 601. The guide seat 609 makes it easier for workers to observe key parameters such as the break point of the tape.

[0022] The threads of the first threaded rod 4 and the second threaded rod 5 are opposite. Because the threads of the first threaded rod 4 and the second threaded rod 5 are opposite, the clamping device 6 moves in opposite directions when the first threaded rod 4 and the second threaded rod 5 rotate.

[0023] The three square blocks 606 are correspondingly set with the three square slots 605. By setting the square blocks 606 and the square slots 605 in a corresponding manner, the third threaded rod 602 can rotate and drive the moving plate 603 to descend, thereby limiting the movement of the moving plate 603 and preventing the moving plate 603 from rotating.

[0024] A rotating seat 604 is provided at the center of the upper end face of the third threaded rod 602, which allows the operator to better manually control the rotation of the third threaded rod 602.

[0025] Working principle: When using the device, first place the tape on the two movable seats 601, then rotate the two third threaded rods 602 to move the movable plate 603 downwards to clamp the tape. The square block 606 at the lower end of the movable plate 603 engages with the square groove 605 at the upper end of the movable seat 601, restricting the rotation of the movable plate 603 so that it can only move axially. The teeth 607 at the lower end of the movable plate 603 mesh with the toothed groove 608 at the upper end of the movable seat 601, increasing the contact area with the tape and thus improving the clamping force. The clamping device 6, through the third threaded rods 602 and the movable plate 603, can adapt to tapes of different widths and thicknesses. At the same time, the teeth 607 and toothed groove 608 effectively prevent the tape from slipping or falling off during the stretching process, ensuring the accuracy of the test results. The rotating frame 701 rotates 90 degrees, and then the moving plate 603 presses down on the clamping device 6 to clamp the tape. Then the rotating frame 701 is rotated back to its original position. During the rotation of the rotating frame 701, the trapezoidal block 705 is squeezed, which compresses the spring 704. After the rotating frame 701 returns to its original position, the spring 704 rebounds, causing the trapezoidal block 705 to pop out inside the three rubber strips 702. The limiting device 7 prevents the clamping device 6 from loosening or shifting during the stretching process, ensuring that the tape is always in a stable clamping state during the test. At the same time, the clamping force of the two clamping devices 6 is precisely adjusted. Then the rotary motor 3 is started to drive the first threaded rod 4 and the second threaded rod 5 to rotate. By setting the threads in opposite directions, the two clamping devices 6 move in opposite directions to perform a stretch test on the tape.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
