[0048] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0049] like Figure 1 As shown, this utility model embodiment provides a polycrystalline silicon packaging bag sample preparation device, including a support plate 10, a support rod 20, a drive assembly 30, and a cutter 40. The support plate 10 includes a first support plate 101, a second support plate 102, and a third support plate 103 that are parallel to each other. One end of the support rod 20 is connected to the first support plate 101, and the other end is connected to the third support plate 103. The drive assembly 30 is disposed on the top of the first support plate 101, and the cutter 40 is disposed on the bottom of the second support plate 102. The second support plate 102 is slidably connected to the support rod 20, and the output end of the drive assembly 30 is connected to the top of the second support plate 102.

[0050] In this embodiment, sliders are provided above the plate surface at each of the four corners of the second support plate 102. Each slider and the plate surface at each corner are connected through a support rod 20. The second support plate 102 can slide on the support rod 20 through the sliders. In addition, support blocks are provided below the plate surface at each of the four corners. The support blocks can slide with the second support plate 102 on the support rod 20 to keep the second support plate 102 in a horizontal state.

[0051] In use, the plastic film is placed on the third support plate 103, and the drive assembly 30 is activated to push the second support plate 102 down along the support rod 20, so that the cutter 40 on the second support plate 102 cuts the plastic film under pressure, thereby replacing manual cutting. This not only improves work efficiency, but also improves the cutting accuracy, reduces human error, and ensures the accuracy of the test data.

[0052] Specifically, such as Figure 2 As shown, the drive assembly 30 includes a motor 301, a reducer 302, a drive gear 303, a driven gear 304, and a screw 305. The motor 301 is connected to the reducer 302, and the output end of the reducer 302 is connected to the drive gear 303. The drive gear 303 meshes with the driven gear 304. The screw 305 includes a smooth section 3051 and a threaded section 3052. The driven gear 304 is sleeved on the smooth section 3051, and the threaded section 3052 passes through the first support plate 101 and is screwed with a nut 50. The outer wall of the nut 50 is fitted with a round tube 60, which is axially sleeved on the outside of the threaded section 3052 and fixed to the second support plate 102 through a connecting part 601. In this embodiment, the part of the nut 50 that connects to the round tube 60 is provided with an external thread structure, and the inner wall of the part of the round tube 60 that mates with the nut 50 is provided with an internal thread structure suitable for cooperating with the external thread structure. In addition, in order to relieve the pressure on the first support plate 101 when the round tube 60 rises, the bottom of the first support plate 101 is provided with a gasket corresponding to the round tube 60.

[0053] In order to reduce the rotational speed and increase the torque, the diameter of the driving gear 303 is smaller than the diameter of the driven gear 304.

[0054] When the drive assembly 30 is started, the motor 301 and the reducer 320 drive the drive gear 303 to rotate, which in turn drives the driven gear 304 to rotate. This drives the screw 305 to rotate, which in turn drives the nut 50 to move the round tube 60 in a straight line on the screw 305, thereby creating a thrust on the second support plate 102.

[0055] More specifically, such as Figure 3 As shown, the driven gear 304 includes a toothed portion 3041 and an assembly portion 3042 integrally formed with the toothed portion 3041. The assembly portion 3042 is engaged with the smooth section 3051 and has a mating groove 30421 recessed inside. The smooth section 3051 has a through hole, through which a pin 30511 adapted to the mating groove 30421 passes. In this embodiment, by using the pin 30511 passing through the smooth section 3051 and the mating groove 3042 of the assembly portion 3042 to engage, relative rotational motion between the driven gear 304 and the screw 305 can be effectively prevented, so that the screw 305 can only rotate synchronously with the rotation of the driven gear 304.

[0056] Furthermore, the motor 301 and the reducer 302 are provided with a housing 306, and the drive gear 303 and the driven gear 304 are provided with a gearbox 307. The housing 306 is located on top of the gearbox 307 to protect the drive assembly 30.

[0057] Furthermore, the bottom of the gearbox 307 is provided with a support base 308, which is fixed on the first support plate 101 to support the drive assembly 30.

[0058] To ensure the smooth rotation of the screw 305, the top end of the smooth section 3051 is connected to the top of the gearbox 307 via a first bearing. A second bearing 70 is fitted on the smooth section 3051 at the lower end of the driven gear 304. The second bearing 70 is fixed on the support base 308, and the outer ring of the second bearing 70 abuts against the assembly part 3042.

[0059] In this embodiment, the actual required packaging bag samples include three types of samples: tensile, puncture, and impact. To improve sample preparation efficiency, such as... Figure 4 As shown, the cutting tool 40 includes a first cutting tool 401, a second cutting tool 402 and a third cutting tool 403. The first cutting tool 401, the second cutting tool 402 and the third cutting tool 403 are evenly distributed at the bottom of the second support plate 102, so that three kinds of samples can be obtained at the same time when the second support plate 102 is pressed down once.

[0060] Specifically, the first cutter 401 is a tensile sample, which is a strip shape of 15×250mm; the second cutter 402 is a puncture sample, which is a circle with a diameter of 100mm; and the third cutter 403 is an impact sample, which is a rectangle of 120×150mm. The cutters 40 are fixed to the bottom of the second support plate 102 by bolts. In this embodiment, the spacing between each pair of the first cutter 401, the second cutter 402, and the third cutter 403 is preferably 2mm, thereby ensuring the accuracy of each sample while reducing waste of plastic film.

[0061] In order to further improve the cutting efficiency, the plastic film can be neatly stacked on the third support plate 103 during use, so that each sample can be pressed down once by the second support plate 102 and multiple packaging bag samples can be obtained at the same time.

[0062] In order to buffer the pressure when the second support plate 102 descends, thereby providing cushioning protection for the third support plate 103, a pad 80 is provided on the top of the third support plate 103; when in use, placing a plastic film on the pad 80 can also have an anti-slip effect.

[0063] Furthermore, the third support plate 103 has a base 90 at its bottom for supporting the entire device.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
