[0030] Embodiment 2

[0031] Reference Figure 2 A plurality of adjusting chutes 10 are provided on the side of the chassis 1 and are respectively located above the stable conveying roller 21 and the stable supporting roller 31. The rotating shaft of the adjusting conveying roller 2 is slidably arranged in the adjusting chutes 10 above the stable conveying roller 21, and the rotating shaft of the adjusting supporting roller 3 is slidably arranged in the adjusting chutes 10 above the stable supporting roller 31.

[0032] Specifically, the adjusting rails 221 are symmetrically arranged inside the chassis 1, and the adjusting frame 22 is slidably arranged on the two adjusting rails 221, and the rotating shafts of the adjusting conveying roller 2 and the adjusting supporting roller 3 are both rotatably connected to the side of the adjusting frame 22 through the adjusting slide slot 10;

[0036] Embodiment 3

[0037] Based on the above embodiments, the present application provides the following embodiments, referring to Figure 1 As shown,

[0038] A number of straw positions 20 are provided on the surfaces of the stable conveying roller 21, the adjustable conveying roller 2, the stable support roller 31 and the adjustable support roller 3. Since the paper straws are cylindrical, they may slip during the conveying process, causing the paper straws to deviate from the conveying angle during the slitting and conveying process, which may easily lead to the slit paper straws having different lengths. Therefore, a number of straw positions 20 are provided on the surfaces of the stable conveying roller 21, the adjustable conveying roller 2, the stable support roller 31 and the adjustable support roller 3. This can effectively ensure that during the slitting process of the paper straws, there will be no deviation or sliding.

[0040] During operation, the entire paper straw to be cut is passed through the stable conveying roller 21 and the adjustable conveying roller 2, and then passed through the stable support roller 31 and the adjustable support roller 3, and then the slitting blade 4 is driven to rotate by the slitting motor 41, and then the sliding seat 40 drives the slitting motor 41 to move toward the slitting window 11. At this time, the cutting of the paper straw can make the end face of the paper straw flush. After the slitting blade 4 cuts the end face of the paper straw flush, the paper straw moves forward. During transportation, the sliding seat 40 moves to retract the slitting motor 41 and the slitting blade 4 into the interior of the chassis 1, and then the angle of the support tube 431 is adjusted by the telescopic adjustment of the slitting cylinder 43 to adjust the angle of the universal shaft 42. At this time, the slitting blade 4 can be adjusted to be tilted, and then the paper straws can be cut at an angle by controlling the movement of the sliding seat 40. At this time, paper straws with one flat end and the other end being an angled end can be obtained. This process is repeated repeatedly, and each paper straw has a flat end and an inclined end.

[0041] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
