[0031] The cutting mechanism 2 can be used to cut the waste material belt 10, and the unit pressing mechanism 1 can be used to press the waste material belt 10 to be cut, and the cutting mechanism 2 and the unit pressing mechanism 1 are located at different heights on the frame 3 after being set. Then, the above-mentioned waste material belt 10 needs to be turned after passing through the unit pressing mechanism 1 to effectively ensure that the waste material belt 10 can extend to the cutting mechanism 2.

[0032] In this regard, the waste cutting device of the composite machine of the utility model also includes a steering mechanism 4. The number of the steering mechanisms 4 can be set according to the number of the unit clamping mechanisms 1. Preferably, a steering mechanism 4 is arranged between adjacent unit clamping mechanisms 1. In this embodiment, there are preferably two steering mechanisms 4.

[0035] The waste cutting device of the composite machine of the utility model further comprises a fixed tensioning column 9 , one end of which is fixedly embedded on the frame 3 .

[0036] When the utility model is in use, the waste material belt 10 can choose the number of continuous unit clamping mechanisms 1 that it needs to pass through according to its length. In this embodiment, the waste material belt 10 preferably needs to pass through two unit clamping mechanisms 1 continuously, and after passing through the last unit clamping mechanism 1, the waste material belt 10 can pass through the nearby steering mechanism 4, and then bypass the tensioning column 5 and the fixed tensioning column 9, and finally enter the cutting mechanism 2 for cutting.

[0037] Specifically, the waste belt 10 needs to pass through the unit pressing mechanism 1 in the following manner. The user can first rotate the nut 15 according to the thickness of the waste belt 10 to make the screw 16 rotate accordingly, and the movable roller seat 14 connected to the screw 16 can move up and down accordingly to adjust the distance between the upper pressing roller 11 and the lower pressing roller 12, so that the distance can adapt to the thickness of the waste belt 10, so that the waste belt 10 can be pressed to a certain extent when passing between the upper pressing roller 11 and the lower pressing roller 12.

[0038] In addition, in order to facilitate the waste material belt 10 to effectively pass through the gap between the upper pressure roller 11 and the lower pressure roller 12 at the beginning, the user can apply a certain force to the movable roller seat 14 through the handle 18, so that the movable roller seat 14 can move slightly to slightly increase the above-mentioned gap. After the waste material belt 10 passes through, the movable roller seat 14 can be reset by relying on the action of the spring 19 to maintain the clamping effect of the upper pressure roller 11 and the lower pressure roller 12.

[0039] When the waste belt 10 needs to pass through the steering mechanism 4, the user can adjust the inclination angle of the inclined plate 41 by turning the handle 44, and the waste belt 10 can bypass the inclined plate 41. The extension direction of the waste belt 10 can be adjusted by changing the direction of the inclined plate 41.

[0040] The specific waste material strip 10 can be cut by the cutting mechanism 2 in the following manner. The user can first rotate the adjusting bolt 241 according to the thickness of the waste material strip 10 so that the limiting roller seat 242 connected to the adjusting bolt 241 can move up and down accordingly to adjust the distance between the knife roller 21 and the limiting roller 22 so that the distance can adapt to the thickness of the waste material strip 10.

[0041] During cutting, the motor 23 can drive the knife roller 21 to rotate, and the rotation of the knife roller 21 can drive the limiting roller 22 to rotate synchronously through the gear, so that the waste material belt 10 can be pulled between the knife roller 21 and the limiting roller 22, and when the cross-cutting knife on the knife roller 21 contacts the limiting roller 22, the waste material belt 10 can be cut to form waste blocks, which can be discharged through the discharge channel 261.

[0042] When the waste material belt 10 needs to bypass the tensioning column 5 , the user can adjust the position of the tensioning column 5 by moving the slider 6 to match different bypassing requirements of the waste material belt 10 .

[0043] On the other hand, when the length of the waste material belt 10 cannot effectively meet the number of unit clamping mechanisms 1 currently passing through after a certain amount of cutting, the user can reduce the number of continuous unit clamping mechanisms 1 passed by the waste material belt 10, and then cut the waste material belt 10 to ensure effective cutting.

[0044] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
