[0019] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0021] To facilitate the understanding of the sampling knife provided by the embodiments of the present application, first, the application scenarios thereof are described. The sampling knife provided by the embodiments of the present application is applied to a sampling device. In the prior art, when rubber is sampled, the sampling knife is used to cut the rubber to take the sample off the rubber. However, the sample is prone to falling off when the rubber is cut. Therefore, the embodiments of the present application provide a sampling knife to improve the sampling effect of the sampling knife. The sampling knife is described in detail below in combination with specific drawings and embodiments.
[0022] Reference Figure 1 illustrated, Figure 1 The structure of the sampling knife provided by the embodiments of the present application is shown in FIG. 1. The sampling knife provided by the embodiments of the present application includes a knife body 10, a top plate 30, and a pin assembly. The knife body 10 is used to cut a sample on rubber. The knife body 10 is a cylindrical structure and can accommodate the cut sample. The top plate 30 is located in the knife body 10. The top plate 30 can move relative to the knife body 10 to push the sample out of the knife body 10 when the sample is molded. The pin assembly is also arranged in the knife body 10. The pin assembly cooperates with the sample to fix the sample, thereby improving the stability of the sample in the knife body 10 and facilitating the sample to be taken off the rubber. The structure of the sampling knife is described in detail below in combination with specific embodiments and drawings.
[0023] Continuing to refer to Figure 1 illustrated, the knife body 10 provided by the embodiments of the present application is a cylindrical structure. For example, the knife body 10 can be open at one end or both ends. In specific arrangements, the embodiments of the present application do not make specific limitations. The knife body 10 has a cutting edge 11 and an accommodation cavity. The cutting edge 11 of the knife body 10 is located at the end (open end) of the knife body 10. When the knife body 10 is a cylindrical structure open at both ends, the cutting edge 11 is located at one of the open ends. That is, when the knife body 10 is a cylindrical structure, the cutting edge 11 is a ring-shaped cutting edge 11. When the rubber is cut, the cutting edge 11 is inserted into the rubber and can cut the sample from the rubber. The sample is retained in the cylindrical structure. The above-mentioned accommodation cavity is the space enclosed by the cylindrical structure. After the sample is cut by the cutting edge 11, the sample can be located in the accommodation cavity and accommodated by the accommodation cavity.
[0024] The top plate 30 is arranged in the knife body 10. The top plate 30 can slide relative to the knife body 10 to push the sample out of the accommodation cavity by the top plate 30 when sampling. In specific arrangements, the sliding direction of the top plate 30 is along the axis direction of the knife body 10. When the knife body 10 cuts the rubber, the top plate 30 is located in the accommodation cavity and away from the cutting edge 11. The top plate 30 and the cutting edge 11 form the above-mentioned accommodation cavity. The sample can be accommodated in the accommodation cavity. When the sample needs to be taken out, the top plate 30 moves towards the cutting edge 11. When the top plate 30 slides to the set position, the top plate 30 pushes the sample out of the accommodation cavity, thereby completing the sampling of the sample.
[0025] The needle assembly is also arranged in the cutter body 10. The needle assembly is used to fix the sample when the sample is in the accommodation cavity. Specifically, the needle assembly includes a plurality of needles 20 for fixing the sample, wherein each needle 20 is fixed in the cutter body 10, and the length direction of each needle 20 is along the axis direction of the cutter body 10. When cooperating with the top plate 30, the tip of each needle 20 can pass through the top plate 30 and is exposed.
[0026] In use, the needle 20 is used to insert into the sample to fix the sample. For example, when the cutting edge 11 cuts the sample, the needle 20 is inserted into the sample at the same time, and the sample and the needle 20 are fixed through the deformation of the sample. When the cutter body 10 is taken out of the rubber, since the sample is fixed by the needle 20, the sample can move synchronously with the cutter body 10 to remain in the accommodation cavity. In addition, when the cutting edge 11 of the cutter body 10 cuts the rubber, if there is a part that is not cut off, the sample piece can be taken off from the rubber through the pulling of the needle 20.
[0027] When the sample piece is taken out of the cutter body 10, the top plate 30 moves and pushes the sample to fall off from the needle 20, thereby completing the sampling of the sample piece.
[0028] As can be seen from the above description, the sampling cutter provided by the embodiment of the present application can fix the rubber sample formed by pre-cutting through the needle 20 before sampling, and can enhance the fixing effect of the sample piece through the needle 20 after cutting, thereby improving the effect that the sampling cutter can carry the sample to separate from the rubber after cutting the sample. Thus, the sampling effect is provided.
[0029] Continuing to refer to Figure 1 As shown, the number of the needle 20 provided by the embodiment of the present application is a plurality, such as three, four, five or the like, which only needs to be able to fix the sample piece. In an implementable scheme, the plurality of needles 20 are arranged around the axis of the cutter body 10. For example, Figure 1 As shown in the middle, the plurality of needles 20 are arranged in a ring shape. When the number of the needle 20 is other number, the needle 20 can be arranged in a ring shape or a plurality of ring shapes. In this way, the stability of the sample can be improved when the sample is fixed by the needle 20.
[0030] In an implementable scheme, the plurality of needles 20 are arranged in an equal interval manner, that is, the distance between any two adjacent needles 20 is equal when the plurality of needles 20 are arranged in a ring shape, so that the stress of the sample piece is uniform when the needle 20 is inserted into the sample piece, which facilitates the separation of the sample piece from the rubber and improves the stability of the sample piece in the cutter body 10.
[0031] Continuing to refer to Figure 1As shown, in one implementation, the cutter body 10 is a cylindrical structure, and when the pins 20 are arranged, the vertical distance d between each pin 20 and the axis of the cutter body 10 and the inner diameter r of the cutter body 10 satisfy: 1 / 4r≤d≤4 / 5r. The above arrangement can ensure that the pins 20 are neither close to the edge of the sample nor close to the center of the sample when the pins 20 are inserted into the sample, thereby ensuring the stability of the stress of the sample, and fewer pins 20 can be used to complete the fixation of the sample.
[0032] When the pins 20 are combined with the cutter body 10, different methods can be used, such as detachable fixed connection or non-detachable fixed connection between the pins 20 and the cutter body 10. For example, each pin 20 is threadedly connected with the cutter body 10. When threadedly connected, threads can be directly formed on the pin 20, and a threaded hole is formed on the cutter body 10 to fixedly connect the pin 20 with the cutter body 10 by threads. When the pin 20 is damaged or worn, it can be directly replaced.
[0033] In an optional solution, when the pin 20 is combined with the cutter body 10, the tip of the pin 20 is exposed outside the cutting edge 11 of the cutter body 10. When the sampling cutter cuts the rubber, the pin 20 is first inserted into the rubber, and then the cutting edge 11 of the sampling cutter is inserted into the rubber. When the above method is used, the sampling cutter can be fixed relative to the rubber by the pin 20, thereby ensuring the stability of the cutting edge 11 when it is inserted into the rubber. In one example, the length of the tip of the pin 20 exposed outside the cutter body 10 is between 5mm and 10mm. For example, the length of the tip of the pin 20 exposed outside the cutting edge 11 of the cutter body 10 can be 5mm, 6mm, 8mm, 10mm, etc. The specific length can be determined according to the thickness of the corresponding rubber. Of course, when the thickness of the rubber is small, the length of the tip of the pin 20 exposed can also be determined according to the thickness of the rubber.
[0034] In an optional solution, the pin 20 is provided with a barb to increase the reliability of the connection between the pin 20 and the sample.
[0035] Continuing to refer to Figure 1 As shown, when the top plate 30 is combined with the pin 20, the tip of the pin 20 is exposed outside the top plate 30. Specifically, the top plate 30 is provided with a passage for the pin 20 to pass through, which can be different, such as a notch or a through hole 31. In one example, the top plate 30 is provided with a plurality of through holes 31, and the plurality of through holes 31 correspond to the plurality of pins 20 one by one; each pin 20 is arranged in the corresponding through hole 31. In the above solution, the pin 20 can directly pass through the top plate 30 through the through hole 31, and when the top plate 30 moves, the through hole 31 in the top plate 30 can also ensure that the pin 20 and the top plate 30 do not interfere with each other.
[0036] The embodiment of the present application further provides a sampling device, which comprises a follow-up seat and the sampling cutter of any one of the above.
[0037] In the above technical solution, the rubber sample is fixed by the insertion needle 20 before sampling, and the fixing effect of the sample is enhanced by the insertion needle 20 after cutting, so that the sampling cutter can carry the sample to separate from the rubber after cutting the sample.
[0038] One or more embodiments of the present specification are intended to cover all such alternatives, modifications and variations falling within the broad scope of the appended claims. Therefore, any omission, modification, equivalent replacement, improvement and the like made in the spirit and principle of one or more embodiments of the present specification should be included in the protection scope of the present disclosure.
[0039] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
