[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1 A tobacco leaf sample cutting device for determining the chemical composition of tobacco leaves, such as Figure 1-4 As shown, the device includes a lower plate 1 and a liftable movable plate 2; several annular cutters 4 are mounted on the movable plate 2; forming holes 11 that mate with the annular cutters 4 are provided at corresponding positions on the lower plate 1; a foot 17 is installed at the lower end of the lower plate 1; a spring 8 is connected to the lower part of the movable plate 2, and a pressure plate 3 is connected to the lower end of the spring 8; clearance holes 10 are provided at corresponding positions on the pressure plate 3. In this embodiment, there is only one pressure plate 3, and several springs 8 are provided.

[0021] The tobacco leaf sample cutting device for determining the chemical composition of tobacco leaves described above places the tobacco leaves to be cut on the lower plate 1. By controlling the moving plate 2 to descend, several ring cutters 4 and pressure plates 3 descend. The pressure plates 3 first come into contact with the tobacco leaves. As they continue to descend, the spring 8 is compressed, and the pressure plates 3 press the tobacco leaves tightly. The ring cutters 4 descend to cut the tobacco leaves, and the cut samples fall below the lower plate 1.

[0022] Specifically, a flexible pad 29 is provided at the lower part of the pressure plate 3. The flexible pad 29 can be a single sheet or a ring, and is located below the clearance hole 10. The function of the flexible pad 29 is to ensure that the area around the cut part remains compressed.

[0023] Specifically, a tray 12 is provided below the lower plate 1; casters 15 are installed at the bottom of the tray 12; and a sample collection dish 13 is placed on the tray 12. By placing the sample collection dish 13 on the tray 12 and pushing the tray 12 into the bottom of the lower plate 1, the cut tobacco leaf samples can fall into the sample collection dish 13 for easy removal.

[0024] Specifically, to prevent the sample collection dish 13 from moving, a placement groove 14 is installed on the tray 12; the sample collection dish 13 is placed in the placement groove 14; a right-angled positioning plate 16 is fixed to the bottom of the lower plate 1. The function of the positioning plate 16 is to position the tray 12 so that the sample collection dish 13 can be positioned exactly below each forming hole 11 of the lower plate 1.

[0025] Specifically, to facilitate the installation and removal of the ring cutter 4, the ring cutter 4 is mounted on the mounting base 24; the upper end face of the movable plate 2 is connected to the mounting part 28; the mounting base 24 is threadedly connected to the mounting part 28. When it is necessary to replace the ring cutter 4, simply unscrew the mounting base 24 for replacement.

[0026] Specifically, the side wall of the ring cutter 4 is connected to a wing plate 25; the bottom of the mounting base 24 has several threaded holes; one end of the screw 27 passes through the retaining ring 26 and the wing plate 25 in sequence and is screwed into the threaded hole of the mounting base 24. The retaining ring 26 clamps the wing plate 25 onto the mounting base 24, thereby enabling the ring cutter 4 to be detachably mounted on the mounting base 24. When the ring cutter 4 needs to be replaced, only the ring cutter 4 needs to be removed and replaced with a new one; there is no need to replace the mounting base 24.

[0027] Specifically, a lead screw 18 is rotatably mounted on one side of the lower plate 1; a nut seat 19 that mates with the lead screw 18 is mounted on the lower end of the movable plate 2; and a guide assembly is mounted on the lower plate 1.

[0028] Specifically, the guide assembly includes a guide post 20 fixed on the lower plate 1; and a guide sleeve 21 that mates with the guide post 20 is installed at the lower end of the movable plate 2.

[0029] Specifically, a top plate 22 is installed above the movable plate 2; the upper end of the guide post 20 is connected to the top plate 22; the upper end of the lead screw 18 is rotatably mounted on the top plate 22; and a drive assembly 23 for driving the lead screw 18 to rotate is installed on the top plate 22.

[0030] In another embodiment, the guide assembly can also use commercially available linear guides to replace the guide post 20 and guide sleeve 21, and a guide rail seat needs to be fixedly installed between the lower plate 1 and the top plate 22, the linear guide is installed on the guide rail seat, and the movable plate 2 is connected to the slider on the linear guide.

[0031] Furthermore, the drive assembly 23 includes a servo motor, a reducer, and a gear set. In another embodiment, the gear set can be replaced with a belt drive assembly or a chain drive assembly.

[0032] Example 2 A tobacco leaf sample cutting device for determining the chemical composition of tobacco leaves, such as Figure 5As shown, compared to Embodiment 1, the number of pressure plates 3 is multiple, and the specific number can be determined according to the number of rows or columns. Each pressure plate 3 is equipped with a number of springs 8. The remaining structure is the same as in Embodiment 1.

[0033] Example 3 A tobacco leaf sample cutting device for determining the chemical composition of tobacco leaves, such as Figure 6-7 As shown, only the connection structure of the pressure plate 2 was changed, and the pressure rod 5, the fixed cylinder 7, the slider 6, and the end cap 9 were added. The rest of the structure is the same as in Example 1.

[0034] Specifically, a fixed cylinder 7 is installed on the movable plate 2; a slider 6 is slidably installed inside the fixed cylinder 7; the upper end of the pressure rod 5 is connected to the slider 6, and the lower end is connected to the pressure plate 3; a spring 8 is sleeved on the outside of the pressure rod 5 and installed between the lower end of the fixed cylinder 7 and the upper end of the pressure plate 3. During descent, the slider 6 is located at the bottom of the fixed cylinder 7. As the movable plate 2 descends, the pressure plate 3 contacts the tobacco leaf. As it continues to descend, the spring 8 is compressed, and the pressure rod 5 and the slider 6 move upward relative to the fixed cylinder 7. The slider 6 and the fixed cylinder 7 cooperate to prevent the pressure plate 3 from moving horizontally.

[0035] Specifically, for easy disassembly and assembly, the top of the fixing cylinder 7 is open and an end cap 9 is installed.

[0036] The working principle of this utility model: The tobacco leaves to be cut are placed on the lower plate 1. The servo motor of the control drive assembly 23 is turned on, driving the lead screw 18 to rotate, which in turn causes the nut seat 19 to descend, thereby moving the moving plate 2, several ring cutters 4, and the pressure plate 3 downwards. The pressure plate 3 first contacts the tobacco leaves. As it continues to descend, the spring 8 is compressed, and the pressure plate 3 presses the tobacco leaves firmly. The ring cutters 4 descend and cut the tobacco leaves. The cut samples fall into the sample collection dish 13 below the lower plate 1. Then, the tray 12 is pulled out to remove the tobacco leaf sample. Then, the servo motor is reversed, causing the moving plate 2 to move upwards and reset.

[0037] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
