Several blade holders are arranged side-by-side between the movable frame and the two partitions. Each blade holder has a cutting blade at its bottom end, and the top ends of the blade holders are movably connected by a first spring.

Furthermore, it is impossible to adjust the spacing between each blade holder according to cutting needs, reducing the adaptability of the adjustment. This solution has low adaptability for adjusting the blade spacing. Utility Model Content

It solves the problem that due to the large number of blade holders and the springs between each blade holder, the compressive force decreases due to the spring force, resulting in different spacing between the blade holders in the middle and making it impossible to adjust the spacing between each blade holder according to cutting needs, thus reducing the adaptability of adjustment.

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0021] Figures 1-4 As an embodiment of this utility model, a tape slitting machine with convenient blade spacing adjustment includes a U-shaped long plate 1. Insert plates 2 are slidably connected to the two ends of the U-shaped long plate 1, and two fixing rods 3 are arranged between the insert plates 2. Several limiting holes 4 are equidistantly opened on both sides of the fixing rods 3, and several sliding plates 5 are slidably connected to their surfaces. Sliding holes 6 that are adapted to the fixing rods 3 are opened on the surface of the sliding plates 5, and directional holes are symmetrically opened on the inner sidewall of the sliding holes 6. Springs 7 are arranged inside the directional holes, and one end of the springs 7 is connected to a limiting bead 8. Threaded holes 9 are opened on both sides of the top of the sliding plates 5 directly above the sliding holes 6, and threaded bolts 10 are arranged inside them.
[0022] The specific problem addressed by this embodiment is to solve the problem that, due to the large number of tool holders and the springs installed between each tool holder, the compressive force decreases due to the influence of the spring force, resulting in different spacing between the tool holders in the middle, and the inability to adjust the spacing between each tool holder according to cutting needs, thus reducing the adaptability of adjustment. This invention utilizes a sliding fit design between the slide plate 5, the sliding hole 6, and the fixed rod 3, combined with the elastic engagement of the spring 7 and the limiting bead 8 with the limiting hole 4. This enables the slide plate 5 to slide freely on the surface of the fixed rod 3 and achieves precise positioning at multiple positions, solving the problem of uneven blade spacing caused by spring distribution in existing technologies. Furthermore, the locking and fixing of the slide plate 5 by the threaded bolt 10 significantly improves the stability during cutting, ensuring adaptability to the slitting needs of tapes of different widths. The sliding guide design of the trapezoidal limiting groove 16 and the limiting rod 11 achieves precise positioning of the cutter 12 during vertical downward cutting, preventing blade deviation. Simultaneously, the detachable connection structure between the limiting rod 11 and the cutter 12 facilitates quick blade replacement or maintenance, solving the problems of complex blade adjustment and low replacement efficiency in traditional slitting machines.
[0023] A trapezoidal limiting groove 16 is provided at the bottom of the slide plate 5, and a limiting rod 11 is slidably connected inside. A cutter 12 is provided at the bottom of the limiting rod 11. An electric push rod 13 is provided at the top of the insert plate 2, and L-shaped support plates 14 are provided at both ends of the U-shaped long plate 1. A connecting plate 15 is provided at the top of the L-shaped support plate 14, and the bottom of the connecting plate 15 is fixedly connected to the top of the electric push rod 13. In this specific embodiment, during operation, the electric push rod 13 drives the insert plate 2 to move down along the vertical guide groove of the L-shaped support plate 14, which drives the fixing rod 3 and the slide plate 5 to descend as a whole, so that the cutter 12 contacts the tape to complete the cutting. When adjusting the blade spacing, the slide plate 5 is manually moved along the fixing rod 3. The spring 7 pushes the limiting bead 8 to engage in the limiting hole 4 at different positions to achieve initial positioning. Then, the threaded bolt 10 is tightened to press against the surface of the fixing rod 3 to lock the slide plate 5. The sliding cooperation between the trapezoidal limiting groove 16 and the limiting rod 11 ensures that the cutter 12 moves vertically and avoids deflection. By using the elastic engagement of the sliding hole 6 and the limiting hole 4, and the double locking of the threaded bolt 10, the blade spacing can be quickly adjusted and stable cutting can be achieved, solving the problem of uneven blade spacing in traditional slitting machines.
[0024] In this specific embodiment, the limiting bead 8 is a quenched steel bead with anti-slip texture on its surface, and its diameter is adapted to the diameter of the limiting hole 4 to form an interference fit.
[0025] The limiting bead 8 is made of hardened steel and has anti-slip texture on its surface. During implementation, when the slide plate 5 slides to the target position, the limiting bead 8 is pushed by the spring 7 and embedded in the limiting hole 4. Its interference fit design increases friction through the anti-slip texture to prevent the slide plate 5 from accidentally shifting when it is not locked. The interference fit and anti-slip texture of the limiting bead 8 improve the reliability of temporary positioning and reduce the micro-movement of the slide plate 5 after adjustment.
[0026] In this specific embodiment, the limiting rod 11 and the cutter 12 are detachably connected by bolts, and the inner wall of the trapezoidal limiting groove 16 is provided with a guide groove and the two sides of the limiting rod 11 are provided with protruding ribs that match the guide groove.
[0027] The limiting rod 11 is connected to the cutter 12 by bolts. When replacing the cutter 12, only the bolts need to be removed to remove the limiting rod 11. The guide groove on the inner wall of the trapezoidal limiting groove 16 slides in cooperation with the protrusions on both sides of the limiting rod 11, ensuring that the cutter 12 always moves in the vertical direction when it is raised and lowered. The detachable cutter 12 simplifies the maintenance process, and the cooperation between the guide groove and the protrusions prevents the cutter 12 from wobbling and improves cutting accuracy.
[0028] In this specific embodiment, a vertical guide groove is provided on the inner sidewall of the L-shaped support plate 14, and the two ends of the insert plate 2 are provided with protrusions that slide with the guide groove, and the surface of the protrusions is coated with a self-lubricating coating.
[0029] The protrusions at both ends of the insert plate 2 are embedded in the vertical guide grooves inside the L-shaped support plate 14. During the lifting and lowering process, the self-lubricating coating on the surface of the protrusions reduces the frictional resistance with the guide groove, making the insert plate 2 move more smoothly. The self-lubricating coating reduces the frictional loss when the insert plate 2 is lifted and lowered, ensuring the continuity of the cutting action.
[0030] In this specific embodiment, a wear-resistant ceramic layer is provided on the surface of the fixing rod 3, and a self-lubricating copper sleeve is embedded in the inner wall of the sliding hole 6 of the sliding plate 5.
[0031] The surface of the fixing rod 3 is coated with a wear-resistant ceramic layer, and the inner wall of the sliding hole 6 of the slide plate 5 is inlaid with a self-lubricating copper sleeve. When the slide plate 5 slides, the copper sleeve contacts the ceramic layer to reduce wear and extend the service life of the fixing rod 3.
[0032] In this specific embodiment, scale lines are provided on the surface of the U-shaped long plate 1 along the length direction and the spacing between the scale lines is consistent with the spacing between the limiting holes 4, and an anti-slip handle is provided at the end of the threaded bolt 10;
[0033] When adjusting the blade spacing, the operator aligns the slide plate 5 with the equidistant distribution of the scale lines on the surface of the U-shaped plate 1 and the limiting holes 4 to achieve intuitive calibration of the spacing. The anti-slip handle at the end of the threaded bolt 10 facilitates tightening and prevents hand slippage.
[0034] Working principle: The electric push rod 13 drives the insert plate 2 to move down along the vertical guide groove of the L-shaped support plate 14, which drives the fixing rod 3 and the slide plate 5 to descend as a whole, so that the cutter 12 at the bottom of the limiting rod 11 contacts the tape to complete the cutting. At the same time, the slide plate 5 is moved along the surface of the fixing rod 3 by manual sliding. The spring 7 pushes the limiting bead 8 to be inserted into the limiting hole 4 to achieve initial positioning. Then, the threaded bolt 10 is tightened to press against the fixing rod 3 to lock the spacing of the slide plate 5. The sliding guide of the trapezoidal limiting groove 16 and the limiting rod 11 ensures that the cutter 12 moves vertically. At the same time, the scale lines on the surface of the U-shaped long plate 1 help to adjust the spacing of the slide plate 5, and finally realize the flexible adjustment of the blade spacing and stable cutting.
