Detailed Embodiments

[0016] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a capping device for the production of sampling tubes, including an annular conveyor belt 1, on which a lid placing device 2, a pressing device 3 and a screwing device 4 are sequentially arranged. There are several placing boxes 5 for placing sampling tubes 13 on the annular conveyor belt 1. A plurality of positioning holes 14 for placing the sampling tubes 13 are opened at the top of the placing box 5. An activity plate 11 capable of accommodating the sampling tubes 13 is movably arranged on several placing boxes 5. A plurality of placing holes 15 corresponding to the sampling tubes 13 one by one are opened on the activity plate 11. Two pressing plates 6 capable of clamping the sampling tubes 13 inward are arranged in the inner cavity of the placing box 5. Driving components for driving the pressing plates 6 to clamp inward are arranged on both sides of the inner side wall of the placing box 5.

[0018] In this embodiment, the lid placing device 2 is located at the first workstation on the annular conveyor belt 1 and is used to place the lid on the sampling tube 13. The device includes one or more robotic arms or vibratory bowls for accurately dropping the lid onto the top of the sampling tube 13.

[0019] The pressing device 3 follows the lid placing device 2 and is used to initially press the lid onto the sampling tube 13, which helps to ensure the initial contact between the lid and the mouth of the sampling tube 13 and prepares for the subsequent screwing operation.

[0020] The screwing device 4 is the last workstation and is used to completely screw the lid onto the sampling tube 13. The device may include one or more rotating heads that can precisely control the rotation force and angle to ensure the tight sealing of the lid.

[0021] It is arranged on the annular conveyor belt 1 for placing and fixing the sampling tubes 13. There are multiple positioning holes 14 at the top of each placing box 5 for accurately positioning the sampling tubes 13. At the same time, an activity plate 11 and a pressing plate 6 are also arranged in the placing box 5 to further fix the sampling tubes 13.

[0022] First, start the annular conveyor belt 1 to make it start circulating. Put the sampling tubes 13 one by one into the positioning holes 14 of the placing box 5, and adjust the activity plate 11 to make it descend and fix the sampling tubes 13. When the sampling tubes 13 reach the lid placing device 2, the lid placing device 2 places the lid on the top of the sampling tubes 13. Subsequently, the pressing device 3 initially presses the lid onto the sampling tubes 13. Finally, the screwing device 4 completely screws the lid onto the sampling tubes 13. After the screwing is completed, the sampling tubes 13 continue to move with the annular conveyor belt 1 to the next workstation or output end.

[0023] Furthermore, the clamping assembly includes several telescopic springs 7 and telescopic rods 16. Several telescopic springs 7 are fixedly connected between the inner side wall of the placing box 5 and both ends of the pressing plate 6. The telescopic rods 16 are fixedly connected between the inner side wall of the placing box 5 and the middle of the pressing plate 6. A plurality of receiving grooves 8 adapted to the sampling tubes 13 are opened on the inner side of the pressing plate 6.

[0024] Further, support plates 10 are provided at both ends of the outer side wall of the placement box 5. Threaded holes 9 are formed in the support plates 10, and bolts 12 pass through the threaded holes 9 and extend to the bottom of the movable plate 11.

[0025] In this embodiment, by rotating the bolt 12 to press against the movable plate 11, by rotating the bolt 12 forward, the bolt 12 is driven to move upward, thereby driving the movable plate 11 to move upward. By rotating the bolt 12 in reverse, the movable plate 11 is driven to move downward, realizing the sampling tubes 13 suitable for different heights, which is more convenient to use.

[0026] Further, sliding grooves 18 are formed in the side wall of the placement box 5. Convex blocks 17 adapted to the sliding grooves 18 are fixedly connected to both ends of the pressing plate 6.

[0027] In this embodiment, through the cooperation between the convex blocks 17 and the sliding grooves 18, the guiding effect of the pressing plate 6 during the moving process can be achieved, avoiding the problem of deviation during the moving process.

[0028] Further, a plurality of support legs 19 are fixedly connected to the bottom of the annular conveyor belt 1.

[0029] In this embodiment, on the basis of placing the support legs 19 at the predetermined positions at the bottom of the annular conveyor belt 1, the support legs 19 are firmly fixed to the base by welding or other fixing methods. For the support legs 19 that need to adjust the height, adjusting machines can be installed so that the height of the support legs 19 can be conveniently adjusted during subsequent maintenance or adjustment.

[0030] The working principle and usage process of the present utility model: After the present utility model is installed, the movable plate 11 is adjusted to adapt to the height of the sampling tube 13, and then the sampling tubes 13 are placed into the placement box 5 one by one, and the sampling tubes 13 are further fixed by the clamping assembly. Then, the annular conveyor belt 1 is started. When the sampling tube 13 reaches the lid placing device 2, the lid placing device 2 places the lid on the top of the sampling tube 13. Subsequently, the pressing device 3 presses the lid onto the sampling tube 13 preliminarily. Finally, the lid screwing device 4 screws the lid completely onto the sampling tube 13. After the lid is screwed, the sampling tube 13 continues to move along with the annular conveyor belt 1 to the next workstation.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
