[0026] Reference Figure 1-4This utility model provides an embodiment of a rapid measurement and cutting device for CT images, comprising a printer 1, characterized in that: an output port 2 is provided on one side of the printer 1, a base 3 is provided at the lower end of the printer 1, a movable door 4 is provided on one side of the base 3, a handle 5 is provided on one side of the movable door 4, a feeding roller 6 is provided inside the base 3, a rotating roller 7 is provided on one side of the feeding roller 6, a rotating shaft 8 is provided at one end of the rotating roller 7, a connecting rod 9 is provided at one end of the rotating shaft 8, a feeding roller 10 is provided on one side of the rotating roller 7, a rubber pad 11 is provided on the surface of the feeding roller 10, a motor 12 is provided at one end of the feeding roller 10, a rotating rod 13 is provided at one end of the motor 12, a cutting device 14 is provided on one side of the feeding roller 10, a measuring device 15 is provided on one side of the cutting device 14, a pulley 16 is provided at the lower end of the measuring device 15, a cylinder 17 is provided at the upper end of the cutting device 14, and a cutting blade 18 is provided at the lower end of the cylinder 17.
[0027] Specifically, the motor 12 drives two sets of feeding rollers 10 to rotate synchronously in opposite directions through a bidirectional gearbox. The gearbox has a built-in electromagnetic clutch that is electrically connected to the PLC controller of the metering device 15. The photoelectric encoder of the metering device 15 monitors the number of rotations of the pulley 16 in real time. When the film length reaches the preset value, the PLC controller sends a stop signal to the motor 12 and a start signal to the cylinder 17 in sequence, and resets after cutting.
[0028] Measurement principle: The measurement device 15 includes a photoelectric encoder and an infrared distance sensor. The film conveying length is calculated by the number of rotations of the pulley 16. Formula: Length = circumference of pulley × number of rotations.
[0029] After the preset length threshold is reached, the encoder signal is transmitted to the PLC controller, triggering the motor 12 to stop.
[0030] Cutting trigger logic: The PLC controller synchronously sends a signal to the solenoid valve of cylinder 17, driving the cutting blade 18 to press down to complete the cutting, and then resets after a delay of 0.5 seconds.
[0031] Specifically, the output port 2 is located on one side of the printer 1 and is rectangular in shape. The printed negative is transmitted through it. The base 3 is fixedly connected to the lower end of the printer 1, providing support for the entire device and improving its overall stability. The movable door 4 is movably connected to one side of the base 3, and a handle 5 is provided on one side. The movable door 4 is opened through the handle 5, making it convenient to open and inspect the interior and replace the negative.
[0032] Specifically, the feeding roller 6 is movably connected inside the base 3, fixing the bottom sheet at its upper end for easy removal. It is movably connected to the inner wall of the base 3. The rotating roller 7 is movably connected to one side of the feeding roller 6, and there are two sets of them. They are used to position the bottom sheet and prevent it from deviating and causing scratches. The rotating shaft 8 is fixedly connected to both ends of the rotating roller 7, increasing the flexibility of the rotating roller 7 and making it rotate synchronously when positioning the bottom sheet to prevent friction from damaging the bottom sheet. One end of the rotating roller 7 is fixedly connected to the connecting rod 9, which increases its stability. The rotating roller 7 is fixedly connected inside the base 3 through the connecting rod 9.
[0033] Specifically, two sets of feeding rollers 10 are movably connected to one side of the rotating roller 7 to transport the substrate to the front end, increasing its convenience. Several sets of rubber pads 11 are fixedly connected to the surface of the feeding roller 10 to increase the friction between the pads and the substrate, making the adsorption force stronger during the transmission process. A motor 12 is fixedly connected to one end of the feeding roller 10, and a rotating rod 13 is fixedly connected to one end of the motor. The feeding roller 10 drives the rotating rod 13 to rotate through the motor 12, which increases its convenience and improves work efficiency.
[0034] Specifically, the two sets of feeding rollers 10 are driven by the same motor 12. The motor output shaft is connected to a bidirectional gearbox, which splits the power into two opposing output shaft rotating rods 13, ensuring that the two rollers rotate synchronously in opposite directions.
[0035] The gearbox has a built-in electromagnetic clutch that can immediately cut off or restore power transmission after receiving a signal from the metering device 15, enabling on-demand start and stop.
[0036] The surface of rubber pad 11 is designed with a serrated texture to enhance friction with the substrate;
[0037] A tension sensor is installed between the rotating roller 7 and the feeding roller 10 to provide real-time feedback on the tightness of the film. The rotation speed is dynamically adjusted by the motor speed control module to prevent the film from being stretched and deformed.
[0038] Specifically, the cutting device 14 is fixedly connected to one side of the feeding roller 10, which is located at the rear end of the printer 1. The metering device 15 is fixedly connected to one side of the cutting device 14, and there are two sets of them. After reaching a certain length, the feeding roller 10 stops to prevent waste of the film. The pulley 16 is movably connected to the lower end of the metering device 15, and there are two sets of them. The film passes over the upper end to prevent wear on the film.
[0039] Film transport path: Feed roller 6 → Rotating roller 7 → Feeding roller 10 → Printer head inside the printer → Output port 2. The rotating roller 7 maintains constant pressure through a spring mechanism to prevent the film from deviating.
[0040] Cutting and printing in tandem: The cut film is pushed by the feed roller 10 to the paper inlet of the printer 1, and the print head completes the image printing on the stationary film, and finally outputs it through the output port 2.
[0041] Specifically, cylinder 17 is fixedly connected to the upper end of cutting device 14, and cutting blade 18 is movably connected to the lower end of cylinder 17. Its blade is beveled, which makes the cutting smoother. A connecting rod 9 is fixedly connected to the upper end of cutting blade 18. One end of connecting rod 9 is fixedly connected to cylinder 17. Cutting blade 18 pushes connecting rod 9 through cylinder 17 to cut, which improves its cutting efficiency.
[0042] Working principle and process: The operator turns on the equipment, connects the computer to printer 1, and prints after adjusting the parameters. The feeding roller 10 drives the rotating rod 13 to rotate through the motor 12, which transmits the film to the printer 1. During the transmission process, the rotating roller 7 stretches and positions the film. The metering device 15 measures the film. When a certain length is reached, the feeding roller 10 stops rotating. The upper cylinder 17 pushes the connecting rod 9 to lower the cutting blade 18 to cut the film. After cutting, the printer prints the film and sends it out through the output port 2.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
