Description

Technical Field

[0001] The utility model relates to the technical field of tape performance testing, in particular to a tape tear resistance performance testing device. Background Technique

[0002] After the tape is formed and produced, it needs to be sampled and tested. The tensile property test of the tape is one of the test items. By applying an external force to cause the tape to deform, it is used to detect whether the tape can maintain tension and not break under the premise of a limited force value. At present, in the process of tape tensile force detection, usually two clamping mechanisms are used to fix both ends of the tape, and then stretching is carried out. However, the ends of the tape are not convenient to be installed in the clamping mechanism, and during the stretching process, the effect of tensile force detection is affected, and the detection efficiency is low.

[0003] After retrieval, Chinese Patent Publication (Announcement) No. 202220231972 discloses a new type of tensile testing machine for tape testing. This patent makes the force on the tape more uniform during the stretching process by increasing the contact force area with the tape. The tensile force detection mechanism drives the tape at the top of the movable plate to stretch, achieving the purpose of tape tensile force detection work. Although the above patent has the function of convenient clamping, the position for fixing the tape is not convenient to clean. Since the tape surface itself has an adhesive layer, during the stretching process after the tape is fixed, the gum on the surface will stick to the clamping position. If not cleaned in time, it will accumulate and make the fixation not firm enough, and it is very troublesome to clean. And the current test device can only perform tensile force tests and does not have the effect of multi-functional tests such as puncture and tensile force, making the function single. Therefore, it is very necessary to design a tape tear resistance performance testing device. Summary of the Utility Model

A lead screw 3 is rotatably connected to the inner side wall of the chute. One end of the lead screw 3 penetrates through the inner side wall of the chute and extends to the outer surface of the top plate 1. A slider 4 is threadedly connected to the outer surface of the lead screw 3. The slider 4 is slidably connected to the chute. One side of the slider 4 is fixedly connected to a tensile force sensor 5. One end of the tensile force sensor 5 is fixedly connected to a movable frame 6;

[0025] In this embodiment, the movable frame 6 is slidably connected to the top plate 1. A transmission roller 7 is rotatably connected to the inner side wall of the movable frame 6. A belt 8 is lapped on the outer surface of the transmission roller 7. A support plate is fixedly connected to one side of the inner wall of the movable frame 6. A threaded column 9 is threadedly connected to the upper surface of the movable frame 6. The bottom end of the threaded column 9 is rotatably connected to a clamping plate 10. A fixed frame 11 is fixedly connected to one side of the upper surface of the top plate 1.

[0026] During specific use, first stick the adhesive layer of the tape downward on the belt 8. Rotate the threaded column 9 to move the clamping plate 10 downward. After continuous rotation, the clamping plate 10 tightly adheres to the belt 8. At the same time, the support plate supports from below so that the tape can be clamped between the belt 8 and the clamping plate 10. After fixing both ends of the tape respectively, by rotating the lead screw 3, the slider 4 is driven to slide outward, so that the tensile force sensor 5 pulls the movable frame 6 to tighten the tape. The lead screw 3 continues to rotate until the tape is torn. The tensile force data is detected by the tensile force sensor 5 to reach the anti-tear test experiment. After the tape is torn, loosen the threaded column 9, and then rotate the transmission roller 7 to drive the belt 8 to rotate the clean surface of the other side of the belt 8 under the clamping plate 10 for the second group of tests. At this time, the belt 8 with adhered glue is exposed, which is convenient for the staff to clean the residual glue.

[0027] In this embodiment, a crank 12 is fixedly connected to one end of the transmission roller 7. A motor 13 is installed on one side of the outer surface of the top plate 1. The output end of the motor 13 is fixedly connected to the lead screw 3.

[0028] During specific use, by starting the motor 13, the lead screw 3 is driven to rotate, which is convenient for the slider 4 to slide under the action of force. By turning the crank 12, it is convenient to rotate the transmission roller 7 so that the belt 8 has a conveying function.

[0029] In this embodiment, a bidirectional screw rod 14 is rotatably connected to one side of the outer surface of the bottom plate 2, and a sliding plate 15 is threadedly connected to the outer surface of the bidirectional screw rod 14.

[0030] During specific use, due to the threaded connection effect between the bidirectional screw rod 14 and the sliding plate 15, after the bidirectional screw rod 14 rotates forward, it can drive the two groups of sliding plates 15 to move away from each other, and after rotating in the reverse direction, it can drive the sliding plates 15 to move closer to each other.

[0032] During specific use, when the two groups of sliding plates 15 are subjected to a force and move away from each other, the top plate 1 is pulled downward through the top rod 16. When the sliding plates 15 move closer to each other, the top plate 1 can be pushed upward through the top rod 16.

[0033] In this embodiment, a support cylinder 17 is fixedly connected to one side of the upper surface of the bottom plate 2, and a column 18 is sleeved on the top end of the support cylinder 17.

[0034] During specific use, by utilizing the sleeved effect of the column 18 in the support cylinder 17 and being supported by four groups of support cylinders 17, the top plate 1 only has the effect of moving up and down.

[0035] In this embodiment, the top plate 1 is fixedly connected to the column 18, and a through hole 19 is opened in the middle of the upper surface of the top plate 1.

[0036] During specific use, by the up and down movement of the top plate 1, the movable frame 6 and the fixed frame 11 can be driven to move up and down, and the through hole 19 is convenient for performing a puncture experiment.

[0037] In this embodiment, a vertical rod 20 is fixedly connected to the middle of the upper surface of the bottom plate 2, a pressure sensor 21 is fixedly connected to the top end of the vertical rod 20, and a puncture needle 22 is threadedly connected to the upper surface of the pressure sensor 21.

[0038] During specific use, the tape is close to the puncture needle 22. After being punctured, the pressure data can be detected by the pressure sensor 21 at this time.

[0039] Working principle: During use, first stick the adhesive layer of the tape downward on the belt 8. By rotating the threaded column 9, the clamping plate 10 moves downward. After continuous rotation, the clamping plate 10 closely adheres to the belt 8. At the same time, the support plate supports from below, so that the tape can be clamped between the belt 8 and the clamping plate 10. After fixing the two ends of the tape respectively, by rotating the screw rod 3, the slider 4 slides outward, so that the tension sensor 5 pulls the movable frame 6 to tighten the tape. The screw rod 3 continues to rotate until the tape is torn. Through the tension sensor 5, the tension data is detected to achieve the anti-tearing test experiment. After the tape is torn, loosen the threaded column 9, and then rotate the driving roller 7 to drive the belt 8, and rotate the surface of the other clean belt 8 under the clamping plate 10 for the second group of tests. At this time, the belt 8 with glue adhered is exposed, which is convenient for the staff to clean the residual glue, so as to achieve convenient cleaning and avoid affecting the next group of tests. When a puncture test is required, first fix the puncture needle 22 on the pressure sensor 21, and then fix the two ends of the tape respectively and rotate the bidirectional screw rod 14, so that the two groups of sliding plates 15 move away from each other under the action force, so as to pull the top plate 1 downward through the ejector rod 16, and the fixing frame 11 and the movable frame 6 descend, driving the tape close to the puncture needle 22. The pressure sensor 21 is supported by the vertical rod 20. After continuously rotating the bidirectional screw rod 14 until the tape is punctured, the test force can be detected through the pressure sensor 21 at this time, achieving the function of not only having a tearing test but also having a puncture test, with complete functions.
