[0002] A Mooney viscometer can measure the shear resistance generated by the rotor rotation of a mixed rubber within a certain temperature, pressure, and time, and is a common instrument for characterizing the processing performance of a mixed rubber. The sample size for Mooney viscosity testing is two circular films with a diameter of approximately 50 mm and a thickness of approximately 6 mm. One of the films has a circular hole with a diameter of approximately 8 mm in the center to facilitate the rotor to pass through. However, when using a cutting knife for sample preparation, since the diameter of the cutting knife for punching is small, it is not stable when placed on the circular film, posing a safety hazard of falling and injuring people. Sometimes, punching even requires the assistance of others. At the same time, when punching, it is not easy to find the center accurately, which will cause uneven placement of the sample, resulting in the rubber material not being able to fill the mold cavity completely, leading to errors in the test results.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-4 , a specimen preparation device for a Mooney viscometer, including a large cutting knife 1. A first card slot 11, a second card slot 12, and a through slot 13 are opened inside the large cutting knife 1. The first card slot 11 is communicated with the through slot 13, and the second card slot 12 is communicated with the through slot 13. Through the design of the through slot 13, the buckle 21 can slide from the first card slot 11 into the second card slot 12. A small cutting knife 2 is movably connected inside the large cutting knife 1.
[0020] Please refer to Figures 2-4 , a buckle 21 is fixedly connected to the outside of the small cutting knife 2. The number of buckles 21 is two, and the two buckles 21 are symmetrically distributed on the small cutting knife 2. Through the design of the buckle 21, the position of the small cutting knife 2 can be conveniently moved. The buckle 21 is slidably connected with the first card slot 11. A push plate 3 is slidably connected inside the small cutting knife 2. A clamping block 31 is fixedly connected to the side of the push plate 3 close to the large cutting knife 1. The clamping block 31 is slidably connected with the small cutting knife 2 and the large cutting knife 1. Through the design of the clamping block 31, the small cutting knife 2 can be limited.
[0021] Please refer to Figures 2-4 , a sliding rod 32 is fixedly connected to the side of the push plate 3 away from the clamping block 31. The sliding rod 32 is slidably connected inside the small cutting knife 2. A limiting ring 33 is fixedly connected inside the small cutting knife 2. The sliding rod 32 is slidably connected inside the limiting ring 33. Through the design of the limiting ring 33, the sliding rod 32 can be limited. A spring 34 is arranged inside the small cutting knife 2. One end of the spring 34 contacts the sliding rod 32, and the other end of the spring 34 contacts the small cutting knife 2. Through the design of the spring 34, the clamping block 31 can be driven to limit the small cutting knife 2.
[0022] The specific implementation process of the present utility model is as follows: When the large cutting knife 1 is in use, when the buckle 21 of the small cutting knife 2 remains in the first card slot 11, the large cutting knife 1 can make a circular film;
[0023] By moving the push plate 3 in a direction away from the large cutting knife 1, the push plate 3 drives the slide rod 32 to slide within the limit ring 33, causing the slide rod 32 to squeeze the spring 34, driving the clamping block 31 to move by the push plate 3, and making the clamping block 31 slide out of the large cutting knife 1, thus releasing the limit on the small cutting knife 2. Then, rotate the buckle 21 so that the buckle 21 slides within the first card slot 11, slides into the through slot 13, and then slides into the second card slot 12 through the through slot 13. In this way, the buckle 21 can drive the small cutting knife 2 to move downward until the bottom of the small cutting knife 2 is flush with the bottom of the large cutting knife 1. Then, release the push plate 3, and the elastic force of the spring 34 can drive the slide rod 32 to move, causing the slide rod 32 to drive the push plate 3 to move, and the push plate 3 to drive the clamping block 31 to slide into the large cutting knife 1, thus re-limiting the small cutting knife 2. At this time, the large cutting knife 1 can produce a circular film with a circular hole in the center.
