Different machines are suitable for slitting different types and specifications of tape.
[0003] The adjustable slitting machine for PCBI fixed tape mainly uses an unwinding mechanism to unfold a large roll of tape, and then a slitting mechanism to cut the tape to a set width. During the cutting process, a transmission mechanism drives the tape to move at a constant speed, ensuring cutting accuracy and stability. The winding mechanism then winds up the slit tape rolls, while a tension control system adjusts the tape tension to prevent slack or stretching deformation during slitting and winding.
[0004] In existing technologies, the width between the blades of some tape slitting machines is fixed, which can only cut tape of a fixed width.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an adjustable slitting device for PCBI fixed tape, comprising two outer casings 1. The outer casings 1 serve as the external frame of the entire slitting device, providing mounting foundations and support for internal components, protecting them from external impacts and dust interference, and ensuring the overall structural stability of the device. A round rod 2 is rotatably connected to one side of each of the two outer casings 1. The round rod 2 enables the rotatable connection between the two outer casings 1 and simultaneously provides support and a rotation shaft for a load-bearing plate 11, allowing the load-bearing plate 11 to rotate within a certain angle range to adapt to the angle adjustment requirements of different working scenarios. The load-bearing plate 11 is fixedly connected to the outer side of the round rod 2. As an important load-bearing platform, the load-bearing plate 11 is fixedly connected to key components such as the protective cover 3 and the slide rail 12, bearing the weight of these components and various forces generated during operation, ensuring the relative position stability of each component during operation.
[0033] A protective cover 3 is fixedly connected to the left side of the support plate 11. The protective cover 3 provides protection and support for the internal components. A motor 4 is fixedly connected inside the protective cover 3. The motor 4 serves as the power source for the entire tool distance adjustment assembly, providing rotational power to the drive wheel 5, which in turn drives the belt 6, threaded rod 7, and other components to operate, ultimately achieving the adjustment of the blade 13 position. The drive end of the motor 4 is fixedly connected to the drive wheel 5. The drive wheel 5 transmits the rotational motion output by the motor 4 to the belt 6, and the friction between the drive wheel 5 and the belt 6 drives the belt 6 to rotate, which is a key link in the power transmission chain. The outer side of the drive wheel 5 is rotatably connected to the belt 6. The belt 6 serves as the intermediate medium for power transmission, transmitting the rotational motion of the drive wheel 5 to the threaded rod 7. The other end of the belt 6 is rotatably connected to the threaded rod 7. The threaded rod 7 converts the motion of the belt 6 into its own rotational motion, and then uses the threaded structure to drive the fixed block 8 to move linearly on the threaded rod 7.
[0034] A fixing block 8 is threadedly connected to the outer side of the threaded rod 7. The fixing block 8, as a key component connecting the threaded rod 7 and the sliding plate 10, transmits its linear movement to the sliding plate 10 under the drive of the threaded rod 7, thereby adjusting the position of the blade 13. Two support blocks 9 are rotatably connected to both ends of the threaded rod 7, providing support and ensuring the stability of the threaded rod 7 during high-speed rotation. The sliding plate 10 is fixedly connected to the rear side of the fixing block 8. Under the drive of the fixing block 8, the sliding plate 10 allows the blade 13 to slide on the slide rail 12, thereby adjusting the distance between the blades 13 to meet the requirements of cutting tape of different widths. Two slide rails 12 are fixedly connected to the front side of the load-bearing plate 11. The two slide rails 12 provide guidance for the movement of the sliding plate 10 and the blade 13, ensuring that the blade 13 can move along a predetermined straight line during the adjustment of position and the cutting of tape. Multiple blades 13 are slidably connected to the outer side of each slide rail 12. The blade 13 is the core execution component of the slitting equipment, which directly cuts the tape and cuts the large roll of tape into multiple small rolls of tape according to the set width. A limit post 14 is fixedly connected to the front side of the blade 13. The limit post 14 slides in the groove on the inner side of the sliding plate 10 to realize the sliding of the blade 13 and thus realize the distance adjustment. Anti-deviation components for preventing tape deviation are provided on the adjacent side of the two machine body shells 1.
[0035] Reference Figures 2 to 4The anti-deviation assembly includes two support plates 16, with both sides of the two support plates 16 fixedly connected to adjacent sides of the two outer casings 1. The support plates 16 serve as the basic support structure for the anti-deviation assembly, connecting and fixing other components. Two slide rails 18 are fixedly connected to the bottom of the support plates 16, providing precise guidance for the movement of sliders 19, ensuring that sliders 19 can slide smoothly along a predetermined straight line. Multiple sliders 19 are slidably connected to the outer side of the slide rails 18. Slider 19 connects to components such as an electric push rod 17, a rack 22, and a clamping block 20, transmitting the pushing or pulling force generated by the electric push rod 17 to the clamping block 20, allowing the clamping block 20 to move and adjust its gripping position on the tape. An electric push rod 17 is fixedly connected to the left side of one of the sliders 19. By controlling the extension and retraction length of the electric push rod 17, the gripping position of the clamping block 20 on the tape can be precisely controlled to adapt to the slitting requirements of tapes of different widths and to correct tape deviation.
[0036] Each slider 19 has a rack 22 fixedly connected to its adjacent side. In the anti-deviation assembly, the rack 22 converts the linear motion of slider 19 into the rotational motion of gear 23, and transmits the rotational motion of gear 23 to other sliders 19, thus achieving synchronous movement of multiple clamping blocks 20. Multiple gears 23 are rotatably connected to the bottom end of the support plate 16. The gears 23 convert linear motion into rotational motion, coordinating the movement of multiple sliders 19 and enabling the clamping blocks 20 to move synchronously. The outer side of the rack 22 is meshed with the outer side of the gear 23. A clamping block 20 is fixedly connected to the bottom end of slider 19. The clamping block 20 acts directly on the tape, clamping and guiding the tape by adjusting its position to prevent deviation during the slitting process.
[0037] Reference Figure 1 , Figure 3 , Figure 4 Two sliders 15 are slidably connected to the rear side of the sliding plate 10, and the rear sides of both sliders 15 are fixedly connected to the front side of the support plate 11. The sliders 15 connect the sliding plate 10 to the support plate 11, allowing the sliding plate 10 to move smoothly in the vertical direction under the action of the fixed block 8. Trapezoidal plates 24 are fixedly connected to the front sides of both casings 1. The trapezoidal plates 24 are mainly used to install and support the film roll 25, providing a stable fulcrum for the rotation of the film roll 25 and ensuring that the film roll 25 can unfold smoothly during the slitting process. The film roll 25 is rotatably connected to the adjacent side of the trapezoidal plates 24.
[0038] The sliding plate 10 has multiple grooves inside, providing space for the installation and sliding of the limiting post 14. This allows the limiting post 14 to be flexibly adjusted within the grooves to meet the limiting position requirements when cutting tapes of different widths. The outer side of the limiting post 14 is slidably connected to the inner side of the groove, and the rear side of the sliding plate 10 is in contact with the front side of the blade 13. The rear sides of the two support blocks 9 are fixedly connected to the inner wall of the protective cover 3, further enhancing the connection stability between the threaded rod 7 and the protective cover 3. The inner side of the blade 13 is slidably connected to the outer side of the support plate 11. The front sides of the two sliders 19 are fixedly connected to the connecting rod 21, which transmits the power of the left slider 19 to the other sliders 19 connected to it. The top end of the connecting rod 21 is in contact with the bottom end of the support plate 16. The top end of the rack 22 is slidably connected to the bottom end of the slide rail 18, and the top end of the slider 19 is in contact with the bottom end of the support plate 16.
[0039] Working principle: The tape master roll is installed on the machine, and the motor 4 is started. The motor 4 starts working, driving the drive wheel 5 fixedly connected to its drive end to start rotating. The outer side of the drive wheel 5 is rotatably connected to the belt 6, which transmits the power of the drive wheel 5 to the threaded rod 7, causing the threaded rod 7 to rotate. The threaded rod 7 is threadedly connected to the fixed block 8, so that the circular motion of the threaded rod 7 is converted into the vertical linear motion of the fixed block 8. The movement of the fixed block 8 causes the sliding plate 10 to slide up and down in the vertical direction. The movement of the sliding plate 10 causes the limiting post 14 to slide inside the groove on the sliding plate 10. At this time, the blade 13 connected to the limiting post 14 also begins to slide on the bearing plate 11, thereby realizing the adjustment of the blade 13 spacing, improving the slitting accuracy and flexibility of the equipment, avoiding tape waste caused by slitting errors, reducing raw material costs, and improving production efficiency.
[0040] When the electric push rod 17 is activated, it begins to operate, causing the two sliders 19, which are fixedly connected to the drive end of the electric push rod 17, to slide on the slide rail 18. Both sliders 19 are connected to the connecting rod 21. At this time, the movement of the electric push rod 17 drives the two sliders 19 to move. Simultaneously, the rack 22 connected to the sliders 19 also begins to move. The gear 23 rotates with the movement of the rack 22, driving the other rack 22 that meshes with it to move. This causes the opposing clamping block 20 to tighten inward, restricting the already slit film roll 25 and preventing the slit film roll 25 from shifting. This ensures that the tape maintains a stable running trajectory during the slitting process, effectively improving the accuracy and quality of slitting, reducing the defect rate caused by tape shift, reducing the frequency of manual intervention and adjustment, and improving production efficiency.
[0041] 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.
