[0027] Specifically, after the mounting plate 4 is fixedly installed on the upper end of the base 5, the fixing plate 8 can be fixedly installed on the upper end of the front end between the two mounting plates 4 by bolts. After the fixing plate 8 is installed and fixed, the first electric telescopic rod 13 can be embedded and installed on the upper end of the fixing plate 8. After the guide plate 15 is fixedly installed on the lower end of the first electric telescopic rod 13, the first electric telescopic rod 13 can drive the guide plate 15 to adjust the height, so that the guide plate 15 can guide and convey the paper straw. Fixing rods are provided on both sides of the upper end of the guide plate 15, and embedding rods are also fixedly installed on both sides of the lower end of the fixing plate 8. After the two fixing rods and the embedding rods are fitted and connected, they can play an auxiliary adjustment role for the lifting and adjusting fixing plate 8.

[0028] After the adjustment plate 2 is movably embedded in the lower end of the front face of the base plate, the second electric telescopic rod 14 can be fixed between the adjustment plate 2 and the inner wall of the base 5. The second electric telescopic rod 14 can drive the adjustment plate 2 to move in position, thereby adjusting the length of the extended paper straw. After the extended end of the paper straw contacts the rear end face of the adjustment plate 2, the first servo motor 11 will drive the cutter disc 7 and blade 3 fixed at the output end to cut the paper straw, thereby cutting the paper straw. At the same time, the conveyor shaft 10 set at the rear end between the mounting plates 4 can play an auxiliary conveying role for the paper straw that needs to be cut.

[0029] Reference Figure 1 and Figure 2 Both first servo motors 11 have a cutter head 7 fixedly mounted on their output ends, and both cutter heads 7 have blades 3 fixedly mounted on their upper ends by bolts.

[0030] Specifically, after the cutter head 7 is installed and fixed at the output end of the first servo motor 11, the blade 3 can be installed and fixed on the upper end face of the cutter head 7 using bolts. This allows the first servo motor 11 to drive the blade 3 to rotate and cut the paper suction tube. The first servo motor 11 adopts existing conventional technical solutions and needs to be connected to an external power supply via a line. The two first servo motors 11 can be connected using a synchronous controller, which can start the two first servo motors 11 synchronously. The synchronous controller is also an existing conventional technical solution.

[0031] Reference Figure 3 and Figure 5 Each of the two mounting plates 4 has a fixed bracket 16 on one side near the front end, and a mounting block 19 is movably embedded at the midpoint of the lower end face of each of the two fixed brackets 16.

[0032] Specifically, after fixing the mounting bracket 16 on one side of the two mounting plates 4, the mounting block 19 can be movably embedded in the lower end face of the two mounting brackets 16, so that the mounting block 19 can move up and down on the lower end face of the mounting bracket 16.

[0033] Reference Figure 3 and Figure 5 Springs 17 are fixedly installed on the upper surfaces of the two mounting plates 4. The upper ends of the two springs 17 are fixedly connected to the inner top surfaces of the two fixing brackets 16 respectively. A rotating shaft 18 is rotatably embedded between the two mounting blocks 19. The positioning shaft 9 is fixedly sleeved on the outer surface of the rotating shaft 18.

At the same time, after the rotating shaft 18 is rotated and embedded between the two mounting blocks 19, the lifting and moving mounting blocks 19 can also drive the rotating shaft 18 to move up and down. After fixing the positioning shaft 9 on the outer surface of the rotating shaft 18, the spring 17 can push the positioning shaft 9 to squeeze the paper straw, thereby assisting in the positioning of the paper straw.

[0035] Reference Figure 3 and Figure 4 One of the two mounting plates 4 has a second servo motor 12 fixedly mounted on one side near the rear end. The output end of the second servo motor 12 is fixedly connected to one end of the conveyor shaft 10.

[0036] Specifically, after the second servo motor 12 is fixedly installed on one side of a mounting plate 4, the output end of the second servo motor 12 can be fixedly connected to one end of the conveyor shaft 10, so that the second servo motor 12 can drive the conveyor shaft 10 to rotate. The outer surface of the conveyor shaft 10 is wrapped with rubber, so that the paper straw can be conveyed better. At the same time, the second servo motor 12 also adopts the existing conventional technical solution, and the second servo motor 12 also needs to be connected to an external power supply through a line.

[0037] Reference Figure 3 and Figure 4 The conveyor shaft 10 is rotatably embedded between the two mounting plates 4 at the rear end, and the end of the second electric telescopic rod 14 away from the adjusting plate 2 is fixedly set on the inner wall of the base 5.

At the same time, after the rear end of the second electric telescopic rod 14 is fixedly connected to the inner wall of one side of the base 5, the second electric telescopic rod 14 can better drive the adjusting plate 2 to move in position.

[0039] Reference Figure 1 and Figure 2 The two mounting plates 4 are fitted with protective plates 1 at the upper end of their front ends, and the base 5 is fixed with support frames 6 on both sides of its lower end.

[0040] Specifically, after the protective plate 1 is fixed to the front end of the mounting plate 4 with bolts, it can surround the outer side of the blade 3, thereby protecting the workers and preventing them from being injured when the blade 3 rotates. The support frame 6 fixed on the lower end of the base 5 can support and fix the cutting equipment.

[0041] Working principle: During use, the operator can adjust the length of the paper straw as needed by extending the second electric telescopic rod 14 via an external controller, thereby driving the adjustment plate 2 to extend and retract. After moving the adjustment plate 2 to the appropriate position, the paper straw can be placed on the upper surface of the base 5. After connecting the second servo motor 12 to the power supply, the second servo motor 12 can be started to drive the conveyor shaft 10 to rotate, thereby conveying the paper straw. At the same time, the first electric telescopic rod 13 can be extended and retracted via the external controller, causing the first electric telescopic rod 13 to drive the guide plate 15 to squeeze the paper straw, thereby guiding and extending the paper straw. After the front end of the paper straw contacts the rear end of the adjustment plate 2, the two first servo motors 11 can be connected to the power supply. After starting the first servo motors 11, the blade 3 can be driven to cut the paper straw.
