The two cutters 64 are arranged in parallel, and the distance between them is equal to the distance of 3 or 5 packaged straws (spoons). Since the packaging bag size of a single defective straw or spoon is small and the cutting distance is insufficient, it is necessary to cut off 1-2 good straws or spoons on both sides of the defect, depending on the packaging size.

[0038] As Figure 3 shown in the figure, the first clamping member 41 includes a moving seat 414, a first lower clamping plate 413, a first upper clamping plate 412 and a first clamping plate driving cylinder 411; the first lower clamping plate 413 is horizontally installed on the top surface of the moving seat 414, and the first clamping plate driving cylinder 411 is installed above the rear side of the moving seat 414 (the side close to the mounting plate 13) through a cylinder bracket and a connecting plate 416, and the cylinder piston rod extends vertically downward to connect the first upper clamping plate 412, and a first clamping opening is formed between the first upper clamping plate 412 and the first lower clamping plate 413.

[0040] The camera 51, the conveyor motor, the cutting cylinder 61, the first clamping plate driving cylinder 411, the second clamping plate driving cylinder 421, the hot melt strip 43 and the servo motor 71 are respectively connected to the controller 80 through wires. The controller 80 is preferably a PLC controller, and its control method is the prior art. An image recognition module is provided in the controller 80. The image recognition module compares the image collected by the camera with the standard image to determine whether there are defects in the packages in the packaging tape. The standard image is a picture of the packaging tape with good straws or spoons. This technology is the prior art, and its principle will not be elaborated.

[0041] When the device is in use:

[0042] The straw packaging tape or the spoon packaging tape is driven by the conveying assembly and moves along the first guiding assembly 31 - the tenth guiding assembly 310. The camera 51 continuously takes pictures of the moving packaging tape and transmits the picture-taking information to the controller 80. When the controller determines that a certain section of the packaging tape is lacking a straw or a spoon, or there are surface defects such as hair on the straw or the spoon, it calculates the time for the packaging tape to move from the detection point to the cutting point. When the time arrives, it controls the first clamping plate driving cylinder 411 and the second clamping plate driving cylinder 421 to act, clamps the defective packaging tape between the first clamping member and the second clamping member, and at the same time, the hot melt strip 43 is electrified and the conveying motor stops rotating. Then, the piston rod of the cutting cylinder 61 extends, driving the cutter to cut the two ends of the defective part of the packaging tape downward. The cut waste falls into the waste collection box through the waste dropping hole 121;

[0043] After cutting is completed, the cutting cylinder 61 retracts, driving the cutter back to the initial position. The servo motor 71 starts, driving the first clamping member 41 to move towards the second clamping member 42. The two ends of the packaging tape from which the defective part has been cut approach and are hot melt-connected into one body through the hot melt strip 43. At the same time, the servo motor 71 stops rotating;

[0044] After hot melting is completed, the hot melt strip 43 is powered off, and the servo motor 71 rotates in the reverse direction, driving the first clamping member 41 back to the initial position; the servo motor 71 stops rotating, and the conveying motor starts, driving the packaging tape to continue moving.

[0045] Embodiment 2

[0046] Refer to Figure 5 , this embodiment is basically the same as Embodiment 1, except that the cutting assembly includes a first cutter 601 and a second cutter 602, and the first cutter and the second cutter are respectively driven by a first rotary cylinder and a second rotary cylinder to rotate and cut the two ends of the defective part of the packaging tape.
