[0003] In view of the above related technologies, the inventor believes that, on the one hand, it is inconvenient to adjust the cutting spacing of traditional slitting machines, and it is difficult to quickly adapt to the slitting requirements of different widths, which affects production efficiency; on the other hand, the tension control of the tape during the slitting process is not good, and the tape is prone to looseness or breakage, resulting in unstable slitting quality. In addition, some slitting machines have complex structures and cumbersome operations, increasing the workload of operators and having a high maintenance cost. Summary of the Invention

[0026] The following is combined with Figure 1-7 This application is described in further detail.

[0027] The present application embodiment discloses a multifunctional PET tape slitting machine, referring to Figure 1-7 , including a base 1, a spacing adjustment component, a reeling component, a guide component and a tensioning component. Two vertical plates 2 are fixedly connected to the surface of the base 1. The tops of the two vertical plates 2 are fixedly connected to a door frame 25. The top wall of the door frame 25 is installed with an electric telescopic rod 3. The output end of the electric telescopic rod 3 passes through the top wall of the door frame 25 and is fixedly connected to a U-shaped plate 4. The top wall of the U-shaped plate 4 is fixedly connected to a servo motor 5. The output end of the servo motor 5 passes through the top wall of the U-shaped plate 4 and is fixedly connected to a screw rod 6 through a coupling. The external thread of the screw rod 6 is connected to a slide plate 7. The side of the slide plate 7 away from the U-shaped plate 8 is tightly fitted with the inner wall of the U-shaped plate 4.

[0028] Specifically, before starting the stripping operation, the operator needs to first determine the position of the cutting knife 11. The electric telescopic rod 3 installed on the top wall of the gantry 25 is started through the control panel 24. The output end of the electric telescopic rod 3 will drive the U-shaped plate 4 to move vertically downward, so that the cutting knife 11 fixed at the bottom of the sliding vertical rod 10 gradually approaches the tape strip 17, completing the preliminary positioning of the cutting knife 11 in the vertical direction. Then, the servo motor 5 on the top wall of the U-shaped plate 4 is started, and the output end of the servo motor 5 drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected to the slide plate 7, and the side of the slide plate 7 away from the U-shaped plate 8 is tightly fitted with the inner wall of the U-shaped plate 4, this structural design enables the rotational motion of the screw rod 6 to be converted into the linear motion of the slide plate 7 along the axial direction of the screw rod 6. The slide 7 is fixedly connected to the U-shaped plate 8, so when the slide 7 moves, it will drive the U-shaped plate 8 to move synchronously, thereby adjusting the position of the cutting blade 11 in the horizontal direction, thereby determining the starting position of the stripping. When the spacing between the cutting blades 11 needs to be adjusted to meet the stripping requirements of tape strips of different widths, the servo motor 5 is also started through the control panel 24. The operation of the servo motor 5 drives the screw 6 to rotate, thereby driving the slide 7 and the U-shaped plate 8 to move. During the movement of the U-shaped plate 8, the adjustment rod 13 fixedly connected to the sliding vertical rod 10 will slide in the inclined groove 12 inside the web of the U-shaped plate 8. The inclined groove 12 has a specific inclination angle, and this design is the key to achieving spacing adjustment. When the adjustment rod 13 slides in the inclined groove 12, according to the movement principle of the inclined plane, its sliding will be converted into a displacement of the sliding vertical rod 10 perpendicular to the tape feeding direction. Multiple sliding vertical rods 10 slide along the two limit rods 9, and the cutting blades 11 installed at the bottom also move accordingly, thereby achieving precise adjustment of the spacing between multiple cutting blades 11.

[0029] Reference Figure 1 、 Figure 2 and Figure 4 The unwinding assembly includes two fixed plates 14 fixedly connected to the left side of the base 1, one of the fixed plates 14 is fixedly connected to the outside of a driving motor 15, the output end of the driving motor 15 passes through the fixed plate 14 and is fixedly connected to a rotating shaft 16 through a coupling, and a tape strip 17 is wrapped around the outside of the rotating shaft 16.

[0030] Specifically, the unwinding assembly is located on the left side of the base 1 and consists of two fixed plates 14, a drive motor 15, and a rotating shaft 16. The drive motor 15 is fixedly mounted on the outside of one of the fixed plates 14, with its output end passing through the fixed plate 14 and fixedly connected to the rotating shaft 16 via a coupling. When the operator starts the drive motor 15 via the control panel 24, the rotor of the drive motor 15 begins to rotate, transmitting power to the rotating shaft 16 via the coupling, driving the rotating shaft 16 to rotate synchronously. The tape strip 17 wrapped around the outside of the rotating shaft 16 is gradually unwound as the rotating shaft 16 rotates, continuously providing tape for subsequent slitting operations and ensuring the continuity of the slitting operation. The tape strip 17 sequentially passes through the gap between the lower curved surface of the tensioning shaft 21 and the two guide rods 22.

[0031] Reference Figure 3 The tensioning assembly includes a U-shaped frame 18 fixedly connected to the surface of the base 1 and located between the vertical plate 2 and the fixed plate 14. The top wall of the U-shaped frame 18 is fixedly connected to a cylinder 19. The output end of the cylinder 19 passes through the top wall of the U-shaped frame 18 and is installed with a U-shaped beam 20. A tensioning shaft 21 is rotatably connected between the inner walls of the two flanges of the U-shaped beam 20.

[0032] Specifically, the tensioning assembly is mounted on the surface of the base 1, located between the riser 2 and the fixed plate 14. It consists of a U-shaped frame 18, a cylinder 19, a U-shaped beam 20, and a tensioning shaft 21. During the slitting process, the cylinder 19 plays a crucial role in ensuring that the tape strip 17 remains taut, thereby ensuring the accuracy and quality of the slitting. The cylinder 19 is fixed to the top wall of the U-shaped frame 18, with its output end extending through the top wall and connected to the U-shaped beam 20. When the tape strip 17 needs to be tightened, the output end of the cylinder 19 is controlled by the control panel 24 to extend downward, driving the U-shaped beam 20 to move downward, and the tensioning shaft 21 connected to the inner wall of the U-shaped beam 20 also moves downward, applying pressure to the tape strip 17 passing through the lower arc surface of the tensioning shaft 21, so that the tape strip 17 is tightened; when the tape strip 17 needs to be loosened, the output end of the cylinder 19 is retracted, and the tensioning shaft 21 moves upward, reducing the pressure on the tape strip 17, thereby realizing flexible adjustment of the tension of the tape strip 17

[0033] Reference Figure 1 and Figure 5 The guide assembly includes two guide rods 22 rotatably connected between the two vertical plates 2 and close to the left end.

[0034] Specifically, the guide assembly consists of two guide rods 22 rotatably connected between the two vertical plates 2, near their left ends. During the slitting process, the tape strip 17 unwound from the unwinding assembly sequentially passes through the gap between the lower curved surface of the tensioning shaft 21 and the two guide rods 22. The two guide rods 22 play a vital role in guiding the tape strip 17, providing a stable conveying path for it. By limiting the horizontal and vertical deviation of the tape strip 17, the tape strip 17 is ensured to follow a fixed trajectory through the cutting area, avoiding problems such as inaccurate strip dimensions or cutting deviations caused by the tape strip 17 running off course, thereby ensuring the accuracy and stability of the slitting process.

[0035] A conveyor belt 23 is installed between the two vertical boards 2 , and a control panel 24 is installed on the outer side of one of the vertical boards 2 .

[0036] After the cutter 11 has completed slitting the tape strips 17, the operator activates the conveyor belt 23 via the control panel 24. This conveyor belt 23 begins to operate, quickly and accurately transporting the slit tape to the designated location for subsequent collection and packaging. The control panel 24 serves as the control center for the entire slitting machine. The operator can use it to start and stop components such as the electric telescopic rod 3, servo motor 5, drive motor 15, and cylinder 19. The operator can also fine-tune and adjust the operating parameters of each component, such as motor speed and cylinder pressure, achieving intelligent control of the entire slitting process to meet diverse production needs.

[0037] The implementation principle of a multifunctional PET tape slitting machine in the embodiment of the present application is as follows: the electric telescopic rod 3 is preferably an LX600 type, the servo motor 5 is preferably an HBS57 type, and the cylinder 19 is preferably a TDA20 type. The multifunctional PET tape slitting machine achieves precise slitting through the coordinated operation of various components. Before the slitting operation, the operator starts the electric telescopic rod 3 and the servo motor 5 on the control panel 24 according to production requirements. The electric telescopic rod 3 is installed on the top wall of the door frame 25, and its output end drives the mold plate 4 to move vertically downward, so that the bottom cutting knife 11 is close to the tape strip 17, completing the initial vertical positioning; the servo motor 5 drives the screw rod 6 to rotate, and the thread opening angle of the outer screw rod 6 is 20 degrees. The self-locking condition of the thread must meet the following formula: self-locking condition = friction coefficient × tan (helix angle) ≥ 1, By utilizing the threaded transmission of the screw rod 6 and the slide plate 7, and the limiting cooperation between the slide plate 7 and the inner wall of the U-shaped plate 4, the slide plate 7 and the U-shaped plate 8 are driven to move horizontally to determine the starting position of the cutting knife 11 stripping. If the stripping width needs to be adjusted, the servo motor 5 is started again. When the U-shaped plate 8 moves, the adjusting rod 13 slides in the inclined groove 12, and its displacement is converted into the movement of the sliding vertical rod 10 perpendicular to the direction of tape conveying, so as to realize the precise adjustment of the spacing of the cutting knife 11. In the unwinding assembly, the driving motor 15 on the left side of the base 1 drives the rotating shaft 16 to rotate through the coupling to continuously release the wound tape strip 17. The released tape strip 17 first passes through the tensioning assembly. A cylinder 19 on the top wall of the U-shaped frame 18 on the surface of the base 1 controls the raising and lowering of the U-shaped beam 20 and the tensioning shaft 21, adjusting the tension of the tape strip 17 and preventing loosening that affects the slitting accuracy. The strip then passes through the guide assembly. Two guide rods 22 between the two vertical plates 2 plan a stable path for the tape strip 17 to prevent deviation. After cutting, the conveyor belt 23 between the vertical plates is activated under the control of the control panel 24, quickly transporting the slit tape to the designated location. Throughout the slitting process, the control panel 24 serves as the core control. The operator can flexibly start and stop components such as the electric telescopic rod 3, servo motor 5, drive motor 15, and cylinder 19, and precisely adjust the operating parameters of each component, achieving automated, intelligent, and high-precision control of the slitting operation, efficiently meeting diverse production needs.
