[0069] Specifically, the conveying assembly is arranged on the supporting assembly, and the supporting assembly is used to support the conveying assembly; the conveying assembly and the slitting assembly are arranged along the first direction 4, where the first direction 4 is as follows Figure 3 In actual use, the conveying assembly can convey the belt 39, and the slitting assembly can slit the belt 39 conveyed by the conveying assembly.

[0070] Furthermore, the supporting assembly includes a platform 36, a supporting column 37 and a supporting platform 38; wherein the platform 36 and the supporting platform 38 are respectively arranged at both ends of the supporting column 37; the conveying assembly is arranged on the supporting platform 38; preferably, the supporting platform 38 is tilted, and an angle of 30° is formed between it and the platform 36.

[0071] Specifically, the slitting assembly has a pad portion and a cutting portion spaced apart from the pad portion along a second direction 5, so that a cutting space 6 is formed between the pad portion and the cutting portion; the second direction 5 here refers to the vertical direction in the figure.

[0072] Furthermore, the receiving portion can receive the belt 39 transmitted by the transmission component, and the cutting portion can cut the belt 39 on the receiving portion.

[0073] Furthermore, the conveying assembly can convey the belt 39 to the cutting space 6 and receive it by the receiving portion. In the cutting space 6, the belt 39 is cut by the cutting portion.

[0074] In summary, the present application utilizes a conveying component to convey the belt 39 to the cutting space 6, utilizes a receiving part to receive the belt 39 in the cutting space 6, and finally utilizes a cutting part to cut the belt 39. The entire process does not require manual operation and work efficiency is significantly improved.

[0075] In this embodiment, the cushioning portion includes a driving member, a first rotating shaft 8 and a cushion sleeve.

[0076] Specifically, the output shaft of the driving member is connected to the first rotating shaft 8, and the first rotating shaft 8 extends along the third direction 19; the third direction 19 is as follows: Figure 5 As shown in ; preferably, the driving member is a driving motor.

[0077] Furthermore, the gasket is sleeved on the first rotating shaft 8; preferably, the gasket is made of rubber. When the belt 39 is cut by the cutting part, the cutting part is likely to cut through the belt 39 and abut against the first rotating shaft 8, which is likely to damage the cutting part. In this embodiment, a gasket is sleeved on the first rotating shaft 8. In this way, the cutting part can be well protected and prevented from being damaged due to abutting against the first rotating shaft 8.

[0078] In this embodiment, the cutting part includes a second rotating shaft 9 and a cutting blade 10 .

[0079] Specifically, the second rotating shaft 9 is arranged parallel to the first rotating shaft 8 , the cutting knife 10 is sleeved on the second rotating shaft 9 , and a cutting space 6 is formed between the sleeve and the cutting knife 10 .

[0080] Furthermore, a plurality of cutting knives 10 are provided, and the plurality of cutting knives 10 are arranged at intervals. The specific number of cutting knives 10 and the distance between adjacent cutting knives 10 are determined by actual conditions. Note that the distance between adjacent cutting knives 10 is the desired width of the belt 39 after slitting.

[0081] Specifically, a main gear is sleeved on the output shaft of the driving motor, a first gear is sleeved on the end of the first rotating shaft 8 close to the driving motor, and a second gear is sleeved on the end of the second rotating shaft 9 close to the driving motor. The main gear is respectively engaged with the first gear and the second gear. That is, when the driving motor is working, the meshing action of the main gear and the first gear and the second gear can drive the first rotating shaft 8 and the second rotating shaft 9 to rotate relative to each other.

[0082] In other words, when the first gear rotates clockwise, the second gear can rotate counterclockwise, that is, the function of transmitting the belt 39 while cutting the belt 39 can be realized.

[0083] In this embodiment, the cutting part further includes an auxiliary block 11 , a handle 12 and a resetting member 13 .

[0084] Specifically, the second rotating shaft 9 passes through the auxiliary block 11 and is connected with the main gear of the driving member.

[0088] It is worth noting that: in actual use, the handle 12 may also be driven by electric drive.

[0089] In this embodiment, the slitting device further comprises a limiting assembly, which is arranged on the supporting assembly and extends toward the auxiliary block 11 , that is, the limiting assembly is arranged on the supporting platform 38 and extends toward the auxiliary block 11 .

[0090] Specifically, the limiting assembly includes a base 14 and an adjusting screw 15. The base 14 is disposed on the supporting platform 38, and the adjusting screw 15 is disposed on a side of the base 14 facing the auxiliary block 11 and is threadedly connected to the base 14.

[0091] During actual use: when the handle 12 is pressed down, the auxiliary block 11 can abut against the head of the screw, that is, the limit assembly can determine the size of the cutting space 6, and the size here refers more to the height of the cutting space 6; then adjusting the height of the adjusting screw 15 exposed from the base 14 can adjust the distance between the auxiliary block 11 and the second rotating shaft 9, and then can adjust the height of the cutting space 6. Adjusting the height of the cutting space 6 can be suitable for belts 39 of different thicknesses.

[0092] In this embodiment, the transmission assembly includes a limiting plate 17 and a first adjustment assembly.

[0093] Specifically, a plurality of limit plates 17 are provided, and the plurality of limit plates 17 extend along the third direction 19 , and a transmission space 20 is formed between adjacent limit plates 17 ; the following takes the case where two limit plates 17 are provided as an example, and a transmission space 20 is formed between the two limit plates 17 .

[0099] Specifically, the limiting plate 17 is disposed on the second adjusting plate, and the adjusting handle 23 is disposed on the first adjusting plate 21 .

[0100] In actual use, the adjusting handle 23 is first used to drive the limit plate 17 to move along the third direction 19 to achieve the initial adjustment of the width of the conveying space 20 (the initial adjustment can also be understood as a coarse adjustment); then by screwing the nut 25 on the screw 24, the first adjustment plate 21 can be moved closer to or away from the second adjustment plate, and then the limit plate 17 can be driven to move along the third direction 19 again to achieve the final adjustment of the size of the conveying space 20 (the final adjustment can be understood as a fine adjustment).

[0104] During actual use, the pin shaft 29 is screwed toward the inside of the limit plate 17. Under the action of the spring, the top connection block can be abutted against the first rotating shaft 8 to prevent the belt 39 from deviating in the conveying space 20. Since the end of the top connection block facing the cutting space 6 is an arc-shaped surface, it can fit the first rotating shaft 8 in a contour.
