[0009] Preferably, there are two equipment plates, and the lead screw is rotatably connected to one equipment plate through a bearing, the limiting rod is fixedly installed to the other equipment plate, the movable frame is movably connected to the lead screw through a nut sleeve, and both the movable frame and the tensile tester are provided with clamping structures.

[0010] Preferably, the hydraulic push rod and the equipment plate are fixedly installed by the base, and the first protective cover, the second protective cover and the hydraulic push rod are fixedly installed by the mounting bracket. The second extension cover and the first protective cover have limiting grooves inside that match the limiting block. The first extension cover and the second extension cover, and the second extension cover and the first protective cover are all movably connected by the limiting block and the limiting groove.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model sets up a first protective cover, a second protective cover, a first extension cover, and a second extension cover. Two hydraulic push rods drive the mounting frame, the first protective cover, and the second protective cover to approach and fit together with the sealing strip. The magnetic block at the top of the first extension cover is attracted and fixed to the bottom of the moving frame. When the first protective cover moves up with the moving frame, it moves on the second extension cover through the limiting block and the limiting groove, and gradually drives the second extension cover to move up and extend.

[0016] Secondly, this utility model, by setting up an electric push rod, a locking frame, a hardness detector, and a detection head, immediately controls the electric push rod to extend the locking frame at the output end as soon as the sealing strip begins to straighten. This causes the locking frame to lock the sealing strip, achieving a limit. Simultaneously, the cylinder is controlled to extend the hardness detector and detection head at the output end. The detection head adheres to the fixed sealing strip and continuously squeezes it to achieve hardness detection. The detection data is sent to the management platform through the hardness detector. Furthermore, a secondary test can be performed when the sealing strip is stretched to a certain extent. The tension and hardness of the sealing strip can be tested sequentially in a short time, improving the testing efficiency. Attached Figure Description

The device plate 2 is fitted with a second extension cover 707. A lead screw 4 is movably mounted on the inner side of the device plate 2. A motor 3 is installed at the bottom end of the lead screw 4, and a nut sleeve 5 is movably mounted on the outer side of the lead screw 4. A movable frame 6 is fixed to one side of the nut sleeve 5, and a movable sleeve head 10 is located on the left side of the movable frame 6.

The second extension cover 707 and the first protective cover 703 are fixedly installed via mounting bracket 702. The interiors of the second extension cover 707 and the first protective cover 703 have limiting grooves that match the limiting block 706. The first extension cover 704 and the second extension cover 707, and the second extension cover 707 and the first protective cover 703 are movably connected via the limiting block 706 and the limiting groove. The first extension cover 704 and the movable frame 6 are fixed by magnetic attraction block 705. The interiors of the first protective cover 703 and the second protective cover 708 are each equipped with the first extension cover 704 and the second extension cover 707. When testing the tensile strength of the sealing strip, first fix both ends of the sealing strip to the clamping structure on the movable frame 6 and the tensile strength tester 8, respectively. At this time, control the motor 3 to run. The internal technology of the motor 3 is existing technology. After the motor 3 runs... The screw 4 at the output end rotates, and when the screw 4 rotates, it drives the moving frame 6 to move upward through the engagement of the thread and the nut sleeve 5. When the moving frame 6 moves upward, the movable sleeve 10 on its left side moves upward along with the moving frame 6 outside the limit rod 11, thereby limiting the smooth movement of the moving frame 6. When the moving frame 6 moves, it drives the sealing strip to straighten and gradually increases the tension. At this time, the tension tester 8 detects the tension, and the hydraulic push rod 701 on the control device board 2 runs. The internal technology of the hydraulic push rod 701 is existing technology. After the two hydraulic push rods 701 run, they drive the mounting bracket 702 at the output end and the first protective cover 703 and the second protective cover 708 to move closer to the sealing strip.

The device immediately controls the pressure when the sealing strip begins to straighten. The electric push rod 901 is operated. The internal technology of the electric push rod 901 is existing technology. After the electric push rod 901 is operated, it drives the locking frame 902 at the output end to extend, so that the locking frame 902 locks the sealing strip when it extends, realizing the limit. At the same time, it controls the operation of the cylinder 903. The cylinder 903 drives the hardness detector 904 and the detection head 905 at the output end to extend. The detection head 905 fits against the fixed sealing strip and continuously squeezes the sealing strip to realize hardness detection. The detection data is sent to the management platform through the hardness detector 904. When the sealing strip is stretched to a certain extent, a secondary detection can be performed. The tension and hardness of the sealing strip can be detected sequentially in a short time, improving the detection efficiency.

[0029] When testing the tensile strength of the sealing strip, first fix both ends of the sealing strip to the clamping structures on the moving frame 6 and the tensile testing instrument 8, respectively. Then, control the motor 3 to run. The internal technology of the motor 3 is existing technology. After the motor 3 runs, it drives the lead screw 4 at the output end to rotate. When the lead screw 4 rotates, it drives the moving frame 6 to move upward through the engagement of the thread and the nut sleeve 5. When the moving frame 6 moves upward, the movable sleeve 10 on its left side moves upward along with the moving frame 6 outside the limit rod 11, thereby limiting the smooth movement of the moving frame 6. The moving frame 6 moves while carrying... The dynamic sealing strip is straightened and the tension is gradually increased. At this time, the tension tester 8 detects the tension, and the hydraulic push rod 701 on the control device board 2 is activated. The internal technology of the hydraulic push rod 701 is existing technology. After the two hydraulic push rods 701 are activated, they drive the mounting bracket 702 at the output end and the first protective cover 703 and the second protective cover 708 to move closer to the sealing strip. Finally, the first protective cover 703 and the second protective cover 708 are attached together, and the magnetic block 705 at the top of the first extension cover 704 is attracted and fixed to the bottom of the moving frame 6. Then the first protective cover 704... 03 As the moving frame 6 moves upward, it moves on the second extension cover 707 via the limiting block 706 and the limiting groove, gradually causing the second extension cover 707 to move upward and extend. Thus, a set of first protective covers 703, second protective covers 708, first extension covers 704, and second extension covers 707 are always located outside the sealing strip, providing protection and preventing it from popping out if the sealing strip breaks. As soon as the sealing strip begins to straighten, the electric push rod 901 is immediately controlled to operate. The internal technology of the electric push rod 901 is existing technology. After the electric push rod 901 operates, it drives the locking frame 9 at the output end. When the 02 extends, the locking frame 902 engages the sealing strip, achieving a limit. Simultaneously, the cylinder 903 is controlled to operate, causing the hardness detector 904 and the detection head 905 at the output end to extend. The detection head 905 adheres to the fixed sealing strip and continuously squeezes the sealing strip to achieve hardness detection. The detection data is sent to the management platform through the hardness detector 904. When the sealing strip is stretched to a certain extent, a secondary detection can be performed. The tension and hardness of the sealing strip can be detected sequentially in a short time, improving detection efficiency.
