It is conceivable that, in order to realize the rotation of the cutting knife, the third power member and the cutting knife need to be rotated simultaneously, specifically, the included angles between the rubber hose and the movable blade 510 and the fixed blade 520 are mainly changed, thereby changing the incision angle of the rubber tube, meeting different process requirements, and if the requirements of fixing two to three angles are met, an air cylinder or a hydraulic motor can be directly used as the fourth driving member 540, and if more angles are required and precise adjustment is required, a servo motor can be used, so that the cutting tool can rotate at different angles, wherein the angle adjustment range of the cutting tool and the rubber tube is between 0 and 180 degrees, specifically, only one of the movable blade 510 or the fixed blade 520 is used as a reference, namely, the angle between the movable blade 510 or the fixed blade 520 and the rubber tube is adjusted within the range of 0 to 180 degrees.

Referring to fig. 1 and 2, in the present embodiment, the clamp includes an upper clamp 610 and a lower clamp 620, the lower clamp 620 is fixed at a discharging side of the pipe cutting assembly 500, the upper clamp 610 is fixed at a driving end of a fifth driving member 630, the fifth driving member 630 drives the upper clamp 610 to move away from or close to the lower clamp 620, when the upper clamp 610 and the lower clamp 620 are overlapped, a pipe matched with the shape of the rubber pipe is formed and the rubber pipe is fixed, and the rubber gasket is coated on a surface of the upper clamp 610 opposite to the lower clamp 620, so as to prevent the rubber pipe from being scratched or pinched.

The pipe cutting device of the embodiment at least has the following beneficial effects: by utilizing the detection assembly 200, whether the rubber tube is disconnected or not in the processing process can be found in time, and the machine can be stopped in time when the rubber tube is disconnected; the straightening assembly 300 is utilized to straighten the rubber tube firstly, and the rubber tube can be prevented from being curled to influence the incision angle and flatness of the rubber tube in the cutting process of the rubber tube; the cutting tool of the pipe cutting assembly 500 can be rotated, so that the angle of the cut of the rubber pipe can be adjusted, and the requirements of the cuts of different rubber pipes can be met; the fixed subassembly 600 of cooperation can guarantee that the rubber tube position keeps fixed when the cutting, can improve the notched precision of rubber tube and roughness effectively to improve production quality.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
