Description

Technical Field

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

[0002] In the tape production process, in order to ensure that its mechanical properties meet the requirements for use, it is usually necessary to cut a section of tape sample and perform a stretching treatment to test its tensile strength.

[0003] When performing tensile testing on tapes, most existing tensile testing devices can only be used in normal temperature and humidity environments. This testing method has certain limitations because some special-purpose tapes (such as industrial tapes for high-temperature environments, waterproof tapes, etc.) may face extreme environmental conditions such as high temperature and high humidity during actual use. Therefore, the tensile performance test results under normal conditions often cannot accurately reflect the performance of these tapes in real use environments, affecting the accuracy of the test data. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a tape tensile testing device that can simulate high temperature and high humidity environments during the testing process, more accurately reflect the performance of special tapes under actual use conditions, and thus effectively ensure the accuracy of test data.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The tape tensile testing device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, the tape tensile testing device of this utility model embodiment may include a housing 10, two clamping mechanisms 30, a rotating mechanism 40, a water supply mechanism 60, and a hot air supply mechanism 70. The top surface of the housing 10 is provided with a through hole 11, and electric push rods 20 are provided on both sides of the housing 10. The piston ends of the two electric push rods 20 pass through the two side walls of the housing 10 and are connected to the two clamping mechanisms 30.

[0024] The rotating mechanism 40 is located on the top surface of the housing 10. The rotating mechanism 40 is connected to the rotating plate 51 through the through hole 11. The bottom surface of the rotating plate 51 is provided with a water storage shell 52 and an air supply pipe 53 on both sides. The bottom surface of the water storage shell 52 is connected to multiple nozzles 54, and the bottom surface of the air supply pipe 53 is connected to multiple blowers 55. The water supply mechanism 60 and the hot air supply mechanism 70 are respectively located on the rotating mechanism 40. The water supply mechanism 60 is connected to the water storage shell 52 through the through hole 11, and the hot air supply mechanism 70 is connected to the air supply pipe 53 through the through hole 11.

[0025] It should be noted that the water storage shell 52 is located above the two clamping mechanisms 30. When the positions of the water storage shell 52 and the air supply pipe 53 are interchanged by the rotating mechanism 40, the air supply pipe 53 will move above the clamping mechanism 30.

[0026] Specifically, the staff first opens the box 10, starts the two electric push rods 20, and shortens the distance between the two clamping mechanisms 30 by controlling the piston end of the electric push rods 20 to adapt to the length of the tape sample. Then, the two ends of the tape sample are placed on the two clamping mechanisms 30 respectively, and the clamping mechanisms 30 are used to clamp and fix the tape sample.

[0027] When the tensile properties of the tape need to be tested under humidified conditions, the staff starts the water supply mechanism 60 to deliver water into the water storage tank 52, and then sprays water onto the tape through multiple nozzles 54 to humidify it. Then, the piston ends of the two electric push rods 20 are controlled to retract to stretch the tape. After the tensile properties test is completed, the tape sample is removed from the clamping mechanism 30 and the condition of the tape is observed.

[0028] When it is necessary to test the tensile properties of the tape under heating, repeat the above steps to clamp the new tape sample using the clamping mechanism 30. Then, the operator starts the rotating mechanism 40 to rotate the rotating plate 51 180 degrees. When the positions of the water tank 52 and the air supply pipe 53 are changed, the air supply pipe 53 is moved above the clamping mechanism 30. The hot air supply mechanism 70 is started, and hot air enters the air supply pipe 53. Then, multiple blowers 55 are used to deliver the hot air to the surface of the tape for heating treatment. Then, the piston ends of the two electric push rods 20 are controlled to retract to test the tensile properties of the tape.

[0029] The tape tensile testing device of this utility model can simulate high temperature and high humidity environment during the testing process, and more accurately reflect the performance of special tapes under actual use conditions, thereby effectively ensuring the accuracy of test data.

[0030] In one embodiment of this utility model, such as Figure 1 As shown, the clamping mechanism 30 includes a clamping frame 31, an adjusting bolt 32, a clamping plate 33, and a guide post 34. The clamping frame 31 is connected to the piston end of the electric push rod 20, the adjusting bolt 32 is threadedly connected to the clamping frame 31, the clamping plate 33 is connected to the adjusting bolt 32, the guide post 34 passes through the clamping frame 31 and is connected to the clamping plate 33, and the guide post 34 is slidably connected to the clamping frame 31.

[0031] It should be noted that by rotating the adjusting bolt 32, the staff can move the clamping plate 33. Under the guidance of the guide post 34, the clamping plate 33 will move in a straight line, placing the tape in the clamping frame 31. The tape is clamped and fixed by the cooperation of the clamping plate 33 and the clamping frame 31.

[0032] In one embodiment of this utility model, such as Figure 1 and Figure 3As shown, the rotating mechanism 40 includes a driver 41, a gear 42, a gear disk 43, multiple support rods 44, an annular groove 45, and a fixed rod 46. The driver 41 is mounted on the housing 10, the gear 42 is mounted on the output end of the driver 41, the gear disk 43 meshes with the gear 42, the multiple support rods 44 are respectively connected to the gear disk 43, and the multiple support rods 44 are respectively slidably connected to the annular groove 45. The annular groove 45 is mounted on the housing 10 and is located outside the through hole 11. The fixed rod 46 is mounted between the gear disk 43 and the rotating plate 51.

[0033] It should be noted that the driver 41 described in this embodiment can be a servo motor. The driver 41 is connected to the controller, which can control the driver 41. The driver 41 drives the gear 42 and the gear disk 43 to rotate, causing the gear disk 43 to rotate 180 degrees, thereby changing the position of the water supply mechanism 60 and the hot air supply mechanism 70. The gear disk 43 will drive the fixed rod 46 and the rotating plate 51 to rotate 180 degrees, thereby changing the position of the water storage shell 52 and the air supply pipe 53 to adapt to the position of the water supply mechanism 60 and the hot air supply mechanism 70, preventing the pipe from twisting. During this process, multiple support rods 44 slide in the annular groove 45 respectively, providing support for the gear disk 43.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the water supply mechanism 60 includes a water tank 61 and a water supply pipe 62. The water tank 61 is mounted on the gear plate 43, and the water supply pipe 62 is connected to the water tank 61. The water supply pipe 62 passes through the rotating plate 51 and is connected to the water storage shell 52.

[0035] It should be noted that the bottom of the water tank 61 is provided with a drain pipe, which passes through the toothed disc 43 and is connected to the water supply pipe 62. The drain pipe is equipped with a valve to control the water supply. The water supply pipe 62 is a flexible hose. The water in the water tank 61 enters the water supply pipe 62 by gravity and then flows into the water storage shell 52. The water is sprayed onto the tape through multiple nozzles 54 to humidify it.

[0036] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the hot air supply mechanism 70 includes a hot air blower 71 and an air duct 72. The hot air blower 71 is mounted on the gear plate 43, and the air duct 72 is connected to the output end of the hot air blower 71. The air duct 72 passes through the gear plate 43 and the rotating plate 51 in sequence and is connected to the air supply pipe 53.

[0037] It should be noted that the hot air blower 71 delivers hot air to the air duct 72, and the hot air then enters the air supply duct 53. Multiple blowers 55 then deliver the hot air to the surface of the conveyor belt for heating treatment.

[0038] In one embodiment of this utility model, such as Figure 1 As shown, the inner bottom wall of the box 10 is provided with a water collection tank 80.

[0039] Understandably, the water collection tank 80 can collect the water sprayed from the nozzle 54, keeping the inside of the housing 10 clean.

[0040] In summary, the tape tensile testing device of this utility model can simulate high temperature and high humidity environments during the testing process, and more accurately reflect the performance of special tapes under actual use conditions, thereby effectively ensuring the accuracy of test data.
