Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , the present invention provides a technical solution: a tensile test device for tape production that is convenient for end positioning, including a support base 1, a lower positioning plate 2, an upper positioning plate 3, an adjusting lead screw 4, an electric push rod 5, a tensile sensor 6, a friction block 7, a fixed toothed plate 8, a first linkage gear 9, a second linkage gear 10, a linkage toothed plate 11, a first magnet 12, a second magnet 13, a transmission piston column 14, and a fastening suction cup 15. The support base 1 has a groove on its surface. One side of the lower positioning plate 2 is slidably connected to the support base 1, and the other side of the lower positioning plate 2 is fixedly connected to the support base 1. The lower positioning plate 2 is slidably connected to the upper positioning plate 3, and the adjusting lead screw 4 is threadedly connected to the upper positioning plate 3. When using this device, first place both ends of the raw material on the surfaces of the two lower positioning plates 2 respectively. By rotating the adjusting lead screw 4, the upper positioning plate 3 is driven to descend, so that the lower positioning plate 2 and the upper positioning plate 3 clamp and limit both ends of the raw material. Subsequently, the electric push rod 5 and the tensile sensor 6 are used to drive one side of the lower positioning plate 2 to slide, facilitating the tensile test of the raw material by the two lower positioning plates 2.

[0031] There are two lower positioning plates 2 on the upper surface of the support base 1. An upper positioning plate 3 is installed above the lower positioning plate 2. One end of the tensile sensor 6 is fixedly connected to the surface of one side of the lower positioning plate 2. The friction block 7 is arc-shaped, and the friction blocks 7 of the lower positioning plate 2 and the upper positioning plate 3 are arranged in a staggered manner. The side surface of the fixed toothed plate 8 is provided with tooth blocks, and the fixed toothed plate 8 penetrates through the surface of the upper positioning plate 3 and is meshed with the first linkage gear 9. When the lower positioning plate 2 and the upper positioning plate 3 clamp the raw material, through the friction blocks 7 arranged in a staggered manner on the surfaces of the lower positioning plate 2 and the upper positioning plate 3, it is convenient to increase the contact area with the raw material, thereby increasing the friction force and enhancing the stability of the raw material clamping.

[0032] A regulating lead screw 4 is rotatably connected to the upper surface of one end of the lower positioning plate 2. An electric push rod 5 is fixedly connected to the inner wall of the groove of the support base 1. A tension sensor 6 is fixedly installed at the output end of the electric push rod 5. Friction blocks 7 are arranged on the opposite surfaces of the lower positioning plate 2 and the upper positioning plate 3. A fixed toothed plate 8 is arranged on the upper surface of the lower positioning plate 2. A cavity is arranged inside the upper positioning plate 3. A first linkage gear 9 is rotatably connected to the inner wall of the cavity of the upper positioning plate 3. Sprockets are arranged at one ends of the rotating shafts of the first linkage gear 9 and the second linkage gear 10. A transmission chain is arranged between the sprocket of the first linkage gear 9 and the sprocket of the second linkage gear 10. A tooth block is arranged on the lower surface of one end of the linkage toothed plate 11. The linkage toothed plate 11 is meshed with the second linkage gear 10 through the tooth block. When the upper positioning plate 3 descends, the upper positioning plate 3 drives the first linkage gear 9 to be meshed with the fixed toothed plate 8, so that the first linkage gear 9 rotates and drives the second linkage gear 10 to rotate through the transmission chain. The second linkage gear 10 drives the linkage toothed plate 11 to slide close to the transmission piston column 14.

[0033] A second linkage gear 10 is rotatably connected to the inner wall of the cavity of the upper positioning plate 3. A linkage toothed plate 11 is slidably connected to the inner wall of the cavity of the upper positioning plate 3. A first magnet 12 is fixedly connected to the lower surface of one end of the linkage toothed plate 11. A groove is arranged on the lower surface of the upper positioning plate 3. A transmission piston column 14 is slidably connected to the inner wall of the groove of the upper positioning plate 3. A second magnet 13 is fixed to the upper end of the transmission piston column 14. A fastening suction cup 15 is fixed to the inner wall of the groove of the upper positioning plate 3. The opposite ends of the first magnet 12 and the second magnet 13 have opposite magnetic poles. A spring is connected between the transmission piston column 14 and the upper positioning plate 3. The transmission piston column 14 is communicated with the fastening suction cup 15. After the first magnet 12 drives the corresponding second magnet 13 through the linkage toothed plate 11, the second magnet 13 is attracted to drive the transmission piston column 14 to slide and extract the air between the fastening suction cup 15 and the raw material, which is convenient for the fastening suction cup 15 to adsorb and fix the raw material under negative pressure, thereby further improving the stability and preventing the raw material from being torn and affecting the test result.

[0034] Working principle: When using the tensile test device for tape production that is convenient for end positioning, first rotate the regulating lead screw 4 to drive the lower positioning plate 2 and the upper positioning plate 3 to merge and clamp the raw material. The friction is increased through the friction blocks 7 for stability. The electric push rod 5 and the tension sensor 6 are used to drive the lower positioning plate 2 on one side to slide for testing. When the upper positioning plate 3 slides, the fixed toothed plate 8 drives the first linkage gear 9 to rotate, so that the first linkage gear 9 drives the second linkage gear 10 to rotate through the transmission chain. The second linkage gear 10 drives the linkage toothed plate 11 to move, so that the first magnet 12 attracts the second magnet 13 to drive the transmission piston column 14 to slide, so that the fastening suction cup 15 is evacuated and adsorbs and fixes the raw material under negative pressure, increasing the overall practicability.
