Description

A tensile strength testing device for adhesive tape Technical Field

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

[0002] Simply put, tape is made by evenly coating an adhesive onto the surface of a tape substrate, using the adhesive to bond objects together, and then using the tape substrate to bond the objects together.

[0003] Existing equipment performs simple tensile tests on tapes, but does not test the performance of tapes of different lengths under tension. However, it still has the following drawbacks: it requires manually unscrewing the fixing knob to adjust the position of the clamp according to the length of the tape, and then using a motor push rod to move the mechanical tension gauge to test the tensile properties of the tape. Therefore, it is very inconvenient to manually adjust the device according to the length of the tape before each test. To address this, this application discloses a tensile strength testing device for tapes. Summary of the Invention

[0004] The purpose of this invention is to address existing problems by providing a tensile strength testing device for adhesive tape.

[0005] This utility model is achieved through the following technical solution: a tensile strength testing device for adhesive tape, including a base, a vertical frame connected to one side of the base, a top frame connected to the top of the frame, symmetrical hanging plates suspended on the outer side of the top frame, an upper roller rotatably connected between the hanging plates, a lower roller arranged below the upper roller, the lower roller rotatably connected to the base through a support plate, a torque meter connected to one end of the lower roller's end shaft, the torque meter electrically connected to a display screen, and a ring handle fitted onto the end of the lower roller away from the torque meter.

[0006] As a further improvement to the above solution, a pin hole is provided through one end shaft of the upper roller.

[0007] The upper roller is restricted from rotating by using pin holes.

[0008] As a further improvement to the above solution, a fixing plate is connected to one side of the top frame, and a pin is movably installed through the fixing plate, with a pull ring connected to the upper end of the pin;

[0009] The pin is supported by a fixed plate, and the pin can be easily lifted and slid by a pull ring.

[0010] As a further improvement to the above solution, the centerline of the pin hole coincides with the centerline of the pin rod.

[0011] This facilitates the insertion of the pin into the pin hole, thereby restricting the rotation of the upper roller.

[0012] As a further improvement to the above solution, a plug groove is provided through the outer curved surface of the upper roller and the lower roller;

[0013] The tape is inserted into the end of the groove, and the tape overlaps and wraps around the lower and upper rollers. The tape end is pressed tightly by the surrounding tape loop.

[0014] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. By rotating the lower roller, the tape overlapping and wrapped on the upper and lower rollers is continuously tightened, so that the torque meter on the shaft of the lower roller senses the magnitude of the torque and displays it on the display screen. In addition, the upper roller is inserted into the pin hole on the shaft of the upper roller through a pin rod to limit the rotation of the upper roller at the upper end of the tape being wrapped, ensuring that the rotation of the lower roller can effectively stretch the tape. This device can be used to stretch tapes of many different lengths, and excess tape can be overlapped and wrapped on the two rollers. Fixing the ends of the tape is also very simple and does not require complicated operations. Attached Figure Description

[0015] Figure 1 is a schematic diagram of the structure of this utility model.

[0016] Figure 2 is a schematic diagram of the structure of the upper and lower rollers with the tape wound on them. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] As shown in Figures 1 and 2, a tensile strength testing device for adhesive tape includes a base 1. A vertical frame 2 is connected to one side of the base 1, and a top frame 3 is connected to the top of the frame 2. Suspension plates 4 are symmetrically suspended on the outside of the top frame 3. An upper roller 5 is rotatably connected between the suspension plates 4. A lower roller 6 is arranged below the upper roller 5. The lower roller 6 is rotatably connected to the base 1 through a support plate 7. One end of the end shaft of the lower roller 6 is connected to a torque meter 8. The torque meter 8 is electrically connected to a display screen 10. A ring handle 11 is fitted onto the end of the lower roller 6 away from the torque meter 8.

[0019] As a further improvement to the above solution, a pin hole 13 is provided through one end shaft of the upper roller 5.

[0020] The upper roller 5 is restricted from rotating by using the pin hole 13.

[0021] As a further improvement to the above solution, a fixing plate 16 is connected to one side of the top frame 3, and a pin 15 is movably installed through the fixing plate 16, with a pull ring 16 connected to the upper end of the pin 15.

[0022] The pin 15 is supported by the fixed plate 16, and the pin 15 can be easily lifted and slid by the pull ring 16.

[0023] As a further improvement to the above solution, the centerline of the pin hole 13 coincides with the centerline of the pin rod 15.

[0024] This facilitates the insertion of the pin 15 into the pin hole 13, thereby restricting the rotation of the upper roller 5.

[0025] As a further improvement to the above solution, a plug groove 17 is provided through the outer curved surface of the upper roller 5 and the lower roller 6;

[0026] The tape is inserted into the end of the tape through the groove 17, and the tape overlaps and wraps around the lower roller 6 and the upper roller 5, and the tape end inside is pressed by the surrounding tape ring.

[0027] As a further improvement to the above solution, a pad 12 is connected at the corner of the lower surface of the base 1 to provide stable support for the base 1.

[0028] The working principle of a tape tensile strength testing device is as follows: by rotating the lower roller 6, the tape overlapping and wound on the upper roller 5 and the lower roller 6 is continuously tightened, so that the torque meter 8 on the end shaft of the lower roller 6 senses the magnitude of the torque and displays it on the display screen. In addition, the upper roller 5 is inserted into the pin hole 13 on the end shaft of the upper roller 5 through the pin rod 15 to limit the rotation of the upper roller 5 at the upper end of the tape being wound, so as to ensure that the rotation of the lower roller 6 can effectively stretch the tape.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
