Description

Technical Field

[0001] This invention belongs to the field of slitting blade assembly technology, and in particular relates to a flat-push slitting blade assembly mechanism. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide sheets of paper, mica tape, or film into multiple narrow strips. In practical applications, depending on the machine's operating conditions and the different materials it processes, the depth of cut needs to be adjusted. However, most current slitting machine blade assemblies currently use a bracket rotation to adjust the feed rate, achieved manually by adjusting the worm gear structure. This is inconvenient for judgment and therefore cannot precisely adjust the depth of cut.

[0003] Therefore, there is an urgent need for a simple and reasonably designed flat-push slitting blade assembly mechanism. By using the adjusting pad on the upper blade shaft component to fit the lower blade shaft component, the cutting depth of the upper and lower blade shaft components can be accurately adjusted, making operation convenient. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flat-push slitting blade assembly mechanism that addresses the shortcomings of the prior art. The mechanism has a simple structure and reasonable design. By using the adjusting pad on the upper blade shaft assembly to fit against the lower blade shaft assembly, the cutting depth of the upper and lower blade shaft assemblies can be accurately adjusted, and the operation is convenient.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a flat-push slitting blade assembly mechanism, characterized in that: it includes two symmetrically arranged sliding bases, an upper blade shaft component and a lower blade shaft component disposed between the two sliding bases, and an adjustment pad block disposed on the upper blade shaft component;

The adjusting shim of the present invention is detachably set on the side of the upper tool holder near the lower tool holder, so that the thickness of the adjusting shim can be adjusted to meet the different cutting depth adjustment requirements of the upper tool shaft component and the lower tool shaft component.

[0039] The bottom of the connecting plate 9-1 is provided with a handle 9-2.

[0040] In this embodiment, the sliding base 20 includes a base 1 and a first slide rail 10-1 and a second slide rail 10-2 arranged parallel to each other on the base 1. The first U-shaped slider 3-1 is arranged on the first slide rail 10-1, and the second U-shaped slider 8-2 is arranged on the second slide rail 10-2. The bottom of the lower tool holder 3 is provided with an integrally formed I-shaped seat 3-2. The first U-shaped slider 3-1 is arranged at the bottom of the I-shaped seat 3-2. The side of the lower tool holder 3 near the upper tool holder 8 is provided with a lower tool shaft pressure plate 5.

[0041] The upper tool holder 8 is provided with an upper tool shaft pressure plate 8-1 at its top, and an L-shaped receiving groove 8-3 is provided at the bottom outer side of the upper tool holder 8. The horizontal top of the L-shaped receiving groove 8-3 is flush with the top of the I-shaped seat 3-2.

[0042] In this embodiment, the upper tool holder 8 is provided with a groove on the side near the lower tool holder 3, a magnetic stone 7 is provided in the groove, the adjusting pad 6 is located in the groove, and the adjusting pad 6 extends out of the top of the upper tool holder 8.

[0043] In this embodiment, the first slide rail 10-1 and the second slide rail 10-2 are attached to the rear limiting plate 2 and the front limiting plate 13.

[0044] In this embodiment, the lower cutter shaft 4 is installed in the lower cutter holder 3 via bearings and then the lower cutter shaft pressure plate 5 is installed via bolts; the upper cutter shaft 9 is installed in the upper cutter holder 8 via bearings and then the upper cutter shaft pressure plate 8-1 is installed via bolts.

[0045] In this embodiment, the bolts on the shim 6 and the lower cutter shaft pressure plate 5 are staggered by adjusting the arrangement.

[0046] In this embodiment, an adjustment pad 6 is provided on the upper tool holder 8, and the adjustment pad 6 is close to the side of the lower tool holder 3 so that the adjustment pad 6 can slide along the sliding base 20 synchronously with the upper tool shaft component until the adjustment pad is in contact with the lower tool holder 3, thereby ensuring that the cutting depth of the upper tool shaft component and the lower tool shaft component is adjusted in place, thereby achieving precise adjustment, convenient operation, and easy intuitive judgment.

[0047] In this embodiment, the adjusting shim 6 is detachably mounted on the side of the upper tool holder 8 near the lower tool holder 3 via a magnetic stone 7, thereby allowing the thickness of the adjusting shim 6 to be adjusted to meet the different cutting depth adjustment requirements of the upper and lower tool shaft components.

[0048] In this embodiment, a rear limiting plate 2 is set to limit the lower tool holder 3, thereby ensuring the limiting of the lower tool shaft component;

[0049] The front limit plate 13 is set to limit the upper tool holder 8 and the push rod 11, thereby ensuring the movement limit of the upper tool shaft component.

[0050] In this embodiment, during actual use, multiple lower blades are installed on the lower blade shaft 4, and multiple upper blades are installed on the upper blade shaft 9 to achieve slitting.

[0051] In this embodiment, the handle 9-2 is provided so that the connecting plate 9-1 can be pushed by the handle 9-2, thereby pushing the upper cutter shaft component closer to the lower cutter shaft component.

[0052] In this embodiment, the extension plate 13-1 is provided to enable the installation of the push rod 11. After the upper cutter shaft component is adjusted to the correct position, the push rod 11 and the extension plate 13-1 are locked by adjusting the nut 11-1, thereby locking the upper cutter shaft component.

[0053] In this embodiment, the L-shaped receiving groove 8-3 is provided so that the upper tool holder 8 can slide along the second slide rail 10-2 to make way for the upper tool shaft component. In addition, after the upper tool shaft component is locked, the upper tool holder 8 presses against the I-shaped seat 3-2 to achieve positioning.

[0054] In this embodiment, the two second slide rails 10-2 on the two sliding bases 20 are arranged between the two first slide rails 10-1.

[0055] In specific use, the lower tool holder 3 and the I-shaped seat 3-2 move along the first slide rail 10-1 via the first U-shaped slider 3-1 until the lower tool holder 3 contacts the rear limiting plate 2;

[0056] Loosen the adjusting nut 11-1, and push the connecting plate 9-1 along the second slide rail 10-2 via the handle 9-2, which pushes the upper tool holder 8 and the upper tool shaft 9 closer to the lower tool holder 3. During this sliding process, the top of the L-shaped receiving groove 8-3 slides along the top of the I-shaped seat 3-2 until the adjusting shim 6 is in contact with the lower tool shaft pressure plate 5. The upper tool shaft component is then adjusted into place. Tighten the adjusting nut 11-1 to engage with the extension plate 13-1, thus locking the top rod 11 and the extension plate 13-1, thereby locking the upper tool shaft component. The L-shaped receiving groove 8-3 of the upper tool holder 8 presses against the top of the I-shaped seat 3-2, thus positioning the lower tool shaft component. By adjusting the shim 6 to engage with the lower tool shaft component, the depth of cut of the upper and lower tool shaft components is precisely adjusted, making operation convenient.
