Description

Technical Field

[0001] The invention mainly relates to the technical field of sample packaging, and in particular to a sample packaging mechanism. Background Art

[0002] Carbon and hydrogen are the main components of coal organic matter, and together with oxygen, they account for more than 95% of coal organic matter; and nitrogen is the only element in coal that exists completely in organic form. Therefore, understanding the carbon, hydrogen and nitrogen content in coal is of great significance for understanding the properties of coal, checking the test results of other indicators, and estimating indicators such as heat, materials, and pollutant emissions during the coal application process.

[0003] The existing methods for detecting carbon, hydrogen and nitrogen in coal are based on a variety of detection instruments, but these detection instruments can only automatically complete the detection process after the sample to be tested enters the detection instrument. For sample packaging work, such as the compression and packaging of the sample carrier (i.e., tin foil cup) of the carbon, hydrogen and nitrogen element analyzer (this process is referred to as sample packaging), it is currently operated manually by staff. Manual operation may cause the tin foil compression and exhaust production results to be affected by human factors, such as mood, finger strength control, and glove cleanliness. Moreover, when a large amount of tin foil needs to be produced, it is also a job that requires a lot of mental and physical labor for the operator.

[0004] How to realize the automatic wrapping and forming of the tin foil cup containing the sample is a problem that the technicians in this field need to solve urgently. Summary of the invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a sample packaging mechanism which has a simple structure, is easy to operate, can effectively reduce labor intensity, and can automatically package and shape samples.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A sample packaging mechanism includes a sample packaging base, a clamping assembly, a push rod, and a driving device. The clamping assembly includes a plurality of triangular clamping blocks. The sample packaging base is used to accommodate the clamping assembly. One end of the push rod is connected to any one of the triangular clamping blocks, and the other end is connected to the driving device. The plurality of triangular clamping blocks are connected in pairs by sliding fit. The driving device is used to drive the push rod to move so as to drive the triangular clamping blocks to move in the opposite direction along the push rod movement direction, and further drive the plurality of triangular clamping blocks to move to form a nearly circular contraction to achieve tight packaging of the sample carrier.

[0008] As a further improvement of the present invention, it also includes a cover plate, which is arranged above the material clamping assembly, and a placement opening for placing the tin foil cup is opened in the center of the cover plate.

[0009] As a further improvement of the present invention: the push rod comprises a first push rod and a second push rod which are arranged in parallel and symmetrically, and the first push rod and the second push rod are respectively connected to the upper top surface and the lower bottom surface of the triangular material clamping block.

[0010] As a further improvement of the present invention: the upper top surface and the lower bottom surface of the triangular material clamping block connected to the push rod are both provided with bosses, and the first push rod and the second push rod are connected to the triangular material clamping block via the bosses.

[0011] As a further improvement of the present invention: a slot hole matching with the boss is provided on the cover plate.

[0012] As a further improvement of the present invention: a guide groove for accommodating the boss is provided on the lower bottom surface of the sample packaging base.

[0013] As a further improvement of the present invention: the bosses are evenly or symmetrically arranged on a plurality of triangular material clamping blocks.

[0014] As a further improvement of the present invention: an opening and closing mechanism is provided under the sample packaging base, and a first sample carrier fixing part and a second sample carrier fixing part are arranged opposite to each other. The first sample carrier fixing part and the second sample carrier fixing part are arranged on the opening and closing mechanism, and the opening and closing mechanism drives the first sample carrier fixing part and the second sample carrier fixing part arranged opposite to each other to move closer to and separate from each other along a straight line.

[0015] As a further improvement of the present invention: a sample injection channel is provided below the first sample carrier fixing part and the second sample carrier fixing part.

[0016] As a further improvement of the present invention: it also includes a base bracket, and the sample bag base is installed on the base bracket.

[0017] As a further improvement of the present invention: it also includes a connecting frame, and the driving device is connected to the base support through the connecting frame.

[0018] Compared with the prior art, the advantages of the present invention are: when the sample packing mechanism of the present invention is used, the sample carrier (such as a tin foil cup) is placed from the sample opening, and the driving device drives the push rod to move, thereby driving the triangular material clamping block connected to the push rod to move. Since multiple triangular material clamping blocks are connected by sliding fit in pairs, when the triangular material clamping block connected to the push rod moves, the other triangular material clamping blocks move synchronously, and the vertex angles of the triangular material clamping blocks approach the center of the circle, thereby gradually closing in a nearly circular shape to complete the clamping of the tin foil cup mouth. The entire mechanism has a simple structure, is easy to operate, and can automatically and efficiently complete the sample packing work of the sample carrier, greatly reducing the labor intensity.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 8 As shown, the present invention discloses a sample packing mechanism, including a sample packing base 1, a material clamping assembly 2, a push rod 3, and a driving device 4. The material clamping assembly 2 includes a plurality of triangular material clamping blocks 21. The sample packing base 1 is used to accommodate the material clamping assembly 2; one end of the push rod 3 is connected to any one of the triangular material clamping blocks 21, and the other end is connected to the driving device 4. The plurality of triangular material clamping blocks 21 are connected in pairs by sliding fit. The driving device 4 is used to drive the push rod 3 to move so as to drive the triangular material clamping blocks 21 to move in the opposite direction along the moving direction of the push rod 3, and further drive the plurality of triangular material clamping blocks 21 to move in a nearly circular shape and gather to achieve sample carrier packing. The whole mechanism has a simple structure, is easy to operate, and can automatically and efficiently complete the sample packing work of the sample carrier, greatly reducing the labor intensity.

[0031] In this embodiment, the material clamping assembly 2 is composed of 9 triangular material clamping blocks 21 of the same size and specification, and the vertex angle of each triangular material clamping block 21 is 40°. It should be noted that the number of triangular material clamping blocks 21 is not limited to 9, as long as the vertex angles of the multiple triangular material clamping blocks 21 add up to 360°.

[0032] In this embodiment, a cover plate 5 is further included. The cover plate 5 is arranged above the material clamping assembly 2, and a placement opening 51 for placing the tin foil cup is opened in the center of the cover plate 5.

[0033] In this embodiment, the push rod 3 includes a first push rod 31 and a second push rod 32 which are arranged in parallel and symmetrically, and the first push rod 31 and the second push rod 32 are respectively connected to the upper top surface and the lower bottom surface of the triangular clamping block 21. The push rod 3 is arranged in parallel and symmetrically, which can ensure that the triangular clamping block 21 is symmetrically stressed from top to bottom, thereby avoiding the jamming phenomenon of multiple triangular clamping blocks 21 when moving in the sample packaging base 1.

[0034] In this embodiment, a boss 6 is also included, and the boss 6 is arranged on the upper top surface and the lower bottom surface of the triangular clamping block 21 connected to the push rod 3, and the first push rod 31 and the second push rod 32 are connected to the triangular clamping block 21 through the boss 6. In the preferred embodiment, in addition to the boss 6 being arranged on the upper top surface and the lower bottom surface of the triangular clamping block 21 connected to the push rod 3, the boss 6 is also arranged on the upper top surface and the lower bottom surface of the other two triangular clamping blocks 21 on both sides of the triangular clamping block 21, which are separated by two triangular clamping blocks 21, so as to ensure that the triangular clamping blocks 21 provided with the boss 6 are evenly arranged, and ensure that the entire clamping assembly 2 can be balanced in force. In addition, the boss 6 on the upper top surface and the lower bottom surface of the triangular clamping block 21 is designed as a symmetrical structure to ensure uniform force, so that the driving force of the driving device 4 can act evenly on the triangular clamping block 21.

[0035] In this embodiment, the cover plate 5 is provided with through holes that match the number of bosses 6 and have matching structures, and the lower bottom surface of the sample packaging base 1 is provided with guide grooves for accommodating the bosses 6, and the number of guide grooves matches the number of bosses 6. In this embodiment, a triangular material clamping block 21 with a boss 6 is provided every two triangular material clamping blocks 21 among the 9 triangular material clamping blocks 21, and three matching through holes are provided on the cover plate 5, and three matching guide grooves are provided on the lower bottom surface of the sample packaging base 1. During installation, the cover plate 5 is first installed on the material clamping assembly 2, and the boss 6 passes through the through hole to connect with the first push rod 31, and then the material clamping assembly 2 is placed in the sample packaging base 1, and the boss 6 on the lower bottom surface of the material clamping assembly 2 passes through the guide groove of the sample packaging base 1 to connect with the second push rod 32.

[0036] In this embodiment, a base bracket 7 is also included, and the sample packaging base 1 is installed on the base bracket 7. The driving device 4 is connected to the base bracket 7 through a connecting frame 8.

[0037] In the present embodiment, an opening and closing mechanism 9 is provided below the sample packaging base 1, and a first sample carrier fixing part 91 and a second sample carrier fixing part 92 are relatively arranged. The first sample carrier fixing part 91 and the second sample carrier fixing part 92 are arranged on the opening and closing mechanism 9, and the opening and closing mechanism 9 drives the first sample carrier fixing part 91 and the second sample carrier fixing part 92 that are relatively arranged to move closer to and apart from each other along a straight line; an injection channel 10 is provided below the first sample carrier fixing part 91 and the second sample carrier fixing part 92.

[0038] When in use, the sample carrier (such as a tin foil cup) is placed from the sample placement port 51 through an external clamping transfer mechanism or manually. At this time, the first sample carrier fixing part 91 and the second sample carrier fixing part 92 are moved closer to each other under the action of the opening and closing mechanism 9, and can clamp the sample carrier to prevent the sample carrier from falling; the driving device 4 drives the push rod 3 to move, thereby driving the triangular clamping block 21 connected to the push rod 3 to move. Since a plurality of triangular clamping blocks 21 are slidably matched with each other, when the triangular clamping block 21 connected to the push rod 3 moves, the other triangular clamping blocks 21 move synchronously, and the top angle of the triangular clamping block 21 approaches the center of the circle, so that it gradually closes in a nearly circular shape to complete the clamping of the tin foil cup mouth. When the sample carrier is wrapped, the first sample carrier fixing part 91 and the second sample carrier fixing part 92 are separated from each other under the action of the opening and closing mechanism 9. At this time, the wrapped sample falls into the analysis instrument from the injection channel 10 below the first sample carrier fixing part 91 and the second sample carrier fixing part 92 for automatic testing.

[0039] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
