AI Technical Summary
During the lifting and lowering test of the existing polymer PVT characteristic curve tester, the telescopic cylinder drives the moving block to move up and down, and cannot limit the moving position, resulting in a shifting position easily, resulting in deviations in the sealing position, and the test data are deviated, and accurate data cannot be obtained.
The lifting mechanism and positioning mechanism are adopted. The lifting mechanism drives the moving block up and down through the electric cylinder, and combines the moving groove to limit the movement direction and stroke. The positioning mechanism uses the moving rod and the positioning rod to cooperate with the limiting groove to detect polymers of different diameters to prevent structural damage.
The automated operation of polymer detection is realized, ensuring the normal use and position accuracy of the mobile block, improving the accuracy of the test data, and adapting to the detection needs of polymers of different diameters.

The bottom of the extension rod 402 is fixedly connected to the output end of the electric cylinder 401. The bottom of the moving block 403 is fixedly connected to the top of the extension rod 402. A moving groove 5 is formed on the front side of the lifting table 3. The rear side of the moving block 403 is movably connected to the inside of the moving groove 5. Limiting columns 6 are fixedly connected to both the left and right sides of the front side of the lifting table 3. The moving block 403 is sleeved on the surface of the limiting column 6. A sealing cover 7 is fixedly connected to the bottom of the moving block 403. An extrusion hole 8 is formed on the bottom of the lifting table 3. The diameter of the extrusion hole 8 is larger than the diameter of the sealing cover 7.
[0029] Through the lifting mechanism 4, when detecting the polymer, the electric cylinder 401 drives the moving block 403 to move up and down, which is convenient for the staff to operate and increases the automation of the device. By setting the moving groove 5, when the moving block 403 moves, the moving direction and stroke of the moving block 403 are restricted, ensuring the normal use of the lifting mechanism 4.
[0030] Embodiment 2
[0031] As Figures 3 - 5 shown, in one embodiment, a placement plate 9 is fixedly connected to the top of the operation table 1. A placement groove 10 is movably connected to the top of the placement plate 9. A positioning block 11 is fixedly connected to the top of the placement plate 9. A cavity 12 is formed inside the positioning block 11. A positioning mechanism 13 is arranged inside the cavity 12. The positioning mechanism 13 includes a moving rod 1301, a positioning rod 1302 and a tension spring 1303. The front side of the moving rod 1301 penetrates through the cavity 12 and extends to the front side of the positioning block 11. The rear side of the moving rod 1301 penetrates to the inside of the cavity 12. The front side of the positioning rod 1302 is fixedly connected to the rear side of the moving rod 1301. The right side of the tension spring 1303 is fixedly connected to the left side of the positioning rod 1302. The left side of the tension spring 1303 is fixedly connected to the inner wall of the cavity 12. The left side of the positioning rod 1302 penetrates to the inside of the placement groove 10. A fixing groove 14 is formed inside the placement groove 10. The left side of the positioning rod 1302 is movably connected to the inside of the fixing groove 14.

The bottom of the limiting rod 16 is movably connected to the inside of the limiting groove 15.
[0032] Through the positioning mechanism 13, when detecting polymers with different diameters, the moving rod 1301 is pulled.

The electric cylinder 401 drives the extension rod 402 to move downward. The extension rod 402 drives the moving block 403 to move downward. The moving block 403 moves downward along the movement track provided by the moving groove 5. The moving block 403 drives the sealing cover 7 to move downward to seal the placement groove 10 and detect the polymer. When detecting polymers of different sizes, pull the moving rod 1301 to the right. The moving rod 1301 drives the positioning rod 1302 to move to the right. While the positioning rod 1302 moves to the right along the movement track provided by the limiting groove 15, the tension spring 1303 is stretched, causing the positioning rod 1302 to move into the cavity 12. At this time, the placement groove 10 can be replaced. After completion, release the moving rod 1301. The positioning rod 1302 is inserted back into the fixing groove 14 by the pulling force of the tension spring 1303 to fix the placement groove 10, and the polymer can be detected again.
