Description

A water vapor barrier membrane tensile tester Technical Field

[0001] This utility model relates to the technical field of diaphragm property testing equipment, specifically to a water vapor barrier membrane tensile tester. Background Technology

[0002] Water vapor barrier film is a thin film product used to prevent water vapor from penetrating. It mainly consists of a waterproof layer, a PET layer, and an adhesive layer. It has excellent water vapor barrier properties and optical properties, and is often used in electronic paper and battery packaging.

[0003] Because water vapor barrier films are applied to corresponding products or equipment, they are stretched taut to ensure tight adhesion. Therefore, it is necessary to test the tensile properties of the barrier film. However, current testing methods mainly involve directly stretching the film to both sides, which cannot accurately detect the film's resilience during the stretching process. To address this, a water vapor barrier film tensile tester is proposed. Summary of the Invention

[0004] The technical problem this invention aims to solve is that current testing methods primarily involve directly stretching the film to both sides, which cannot accurately detect the film's resilience during the stretching process. This invention provides a water vapor barrier film tensile tester that can detect the resilience of the barrier film during the stretching test, thereby improving the comprehensiveness and practicality of the test.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a water vapor barrier membrane tensile tester, including a processing table, a slide rail fixedly connected to the middle of the top side wall of the processing table, a fixed column fixedly connected to the top of the processing table and near one end edge, a tension column provided on the top of the slide rail, an inner groove opened in the tension column, a follower column slidably connected in the inner groove, an embedding groove opened on one end side wall of the inner groove, and a pressure sensor detachably embedded in the embedding groove.

[0006] As a preferred technical solution of this utility model, the top sidewall of the follower column is uniformly provided with grooves, the grooves are funnel-shaped, a cover plate is provided above the follower column, a pressing column is fixedly connected to the bottom of the cover plate and the sidewall opposite to the groove, and a rubber pad is fixedly connected to the inner wall of the groove.

[0007] As a preferred technical solution of this utility model, a follower block is fixedly connected to one side wall of the cover plate, a threaded post is threadedly connected in the middle of the follower block, a bearing block is rotatably connected to the bottom end of the threaded post, and the bearing block is fixedly connected to one side wall of the follower post through one end.

[0008] As a preferred technical solution of this utility model, a bottom groove is provided at the bottom of the inner groove and near both sides. A limiting block is slidably connected in the bottom groove. The limiting block is fixedly connected to the bottom side wall of the follower column through the top end. The structure of the fixed column is the same as that of the follower column.

[0009] As a preferred technical solution of this utility model, a telescopic rod is detachably embedded in one end of the slide rail, a slider is slidably connected inside the slide rail, and the slider is detachably connected to the output end of the telescopic rod at one end. Rollers are uniformly rotatably connected to the bottom side wall of the slide rail.

[0010] This invention has the following advantages: A pressure sensor is connected to one side wall of the inner groove. As the tension column moves, the follower column will gradually approach the pressure sensor under the pull of the barrier membrane. As the barrier membrane is gradually stretched and unfolded, the counter-tension force on the follower column becomes greater, and the pressure acting on the pressure sensor becomes greater. Therefore, the data transmitted by the pressure sensor can be used to determine the reverse rebound tension generated by the barrier membrane during the stretching test, thereby realizing the detection of the barrier membrane's rebound force data and improving the practicality and comprehensiveness of the test.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to Figures 1-3. The present invention provides a water vapor barrier membrane tensile tester, which includes a processing table 1. A slide rail 2 is fixedly connected to the middle of the top side wall of the processing table 1. A fixed column 13 is fixedly connected to the top of the processing table 1 and near one edge. A tension column 4 is provided on the top of the slide rail 2. An inner groove 5 is opened in the tension column 4. A follower column 6 is slidably connected in the inner groove 5. An embedding groove 14 is opened on one side wall of the inner groove 5. A pressure sensor 15 is detachably embedded in the embedding groove 14.

[0017] The top sidewall of the follower column 6 is evenly provided with grooves 7, which are funnel-shaped structures. A cover plate 8 is provided above the follower column 6. A pressing column 9 is fixedly connected to the bottom of the cover plate 8 and the sidewall opposite to the groove 7. A rubber pad is fixedly connected to the inner wall of the groove 7. A follower block 10 is fixedly connected to one sidewall of the cover plate 8. A threaded column 11 is threadedly connected in the middle of the follower block 10. A bearing block 12 is rotatably connected to the bottom end of the threaded column 11. The bearing block 12 is fixedly connected to one sidewall of the follower column 6 through one end.

[0018] The technical effects of this solution are as follows: Since the follower column 6 slides within the inner groove 5, when the tension column 4 moves, the follower column 6 will move in the opposite direction under the tension of the barrier membrane, thereby causing the follower column 6 to adhere to the pressure sensor 15. As the tension column 4 continues to move, it will cause the barrier membrane to unfold, generating a reaction force. The elasticity of the barrier membrane during the stretching process can be detected by the pressure exerted on the pressure sensor 15 by the reaction force. Furthermore, the tensile strength of the barrier membrane can be determined by the tension generated by the telescopic rod 18 based on the stretching of the barrier membrane driven by the tension column 4. Through these two detection effects, the comprehensiveness of the detection can be guaranteed, and the practicality of the equipment can be improved.

[0019] The inner groove 5 has bottom grooves 16 at the bottom and near both sides. A limiting block 17 is slidably connected in the bottom groove 16. The limiting block 17 is fixedly connected to the bottom side wall of the follower column 6 through the top. The structure of the fixed column 13 is the same as that of the follower column 6. A telescopic rod 18 is detachably embedded in the side wall of one end of the slide rail 2. A slider 3 is slidably connected in the slide rail 2. The slider 3 is detachably connected to the output end of the telescopic rod 18 through one end. Rollers 19 are uniformly rotatably connected to the bottom side wall of the slide rail 2.

[0020] The technical effects of this solution are as follows: the bottom groove 16 and the limiting block 17 ensure the smooth movement of the follower column 6 in the inner groove 5, avoiding skewness that would affect the detection of pressure. At the same time, the rotating connecting roller 19 at the bottom of the slide rail 2 reduces the friction when the slider 3 moves. Connecting the slider 3 to the output end of the telescopic rod 18 can drive the slider 3 and the tension column 4 to move along the slide rail 2. The tension data generated when the tension column 4 is pulled by the tension sensor 15 can be connected to the tension sensor 15.

[0021] Specifically, in use, the two ends of the barrier membrane are placed on the fixed column 13 and the follower column 6. Then, the threaded column 11 is rotated to drive the cover plate 8 to rise and fall through the threaded connection. As the cover plate 8 falls, the pressing column 9 will be inserted into the corresponding groove 7, thereby pressing the ends of the barrier membrane into the groove 7 to fix the two ends of the barrier membrane. However, it is necessary to ensure that the barrier membrane is taut and unfolded. Then, the telescopic rod 18 is activated to drive the slider 3 to move along the slide rail 2. This will cause the fixed barrier membrane to gradually stretch. As the stretching continues, the tensile strength of the barrier membrane can be tested. Because the follower column 6 slides in the inner groove 5, as the tension column 4 moves, the follower column 6 will gradually approach the pressure sensor 15. As the tension column 4 moves, the follower column 6 will press on the pressure sensor 15 under the reaction force of the barrier membrane. In this way, the rebound tension generated during the barrier membrane test can be obtained through the pressure data transmitted by the pressure sensor 15. This device realizes dual data detection to improve practicality and comprehensiveness.

[0022] A roller 19 is rotatably connected to the bottom side wall of the slide rail 2, and a tensioner is connected to the output end of the telescopic rod 18. The tensioner is connected to the slider 3, so the tension that the barrier membrane can withstand and its maximum extensibility can be detected. The roller 19 reduces the friction of the slider 3, improves its service life and the smoothness of the movement of the tension column 4.
