Description

Technical Field

[0001] This utility model relates to the field of steel strip slitting technology, and in particular to an integrated device for longitudinal slitting, unslitting and rewinding of medical steel strips. Background Technology

[0002] After the steel strip is rolled, it is coiled to form a steel strip coil. However, it needs to be longitudinally slit into steel strips of different widths according to the production needs of different customers. For example, Chinese patent CN208392134U discloses a longitudinal slitting mechanism for stainless steel strip, which includes a conveying roller, a pressure roller support, an adjusting pressure roller, and a slitting knife assembly arranged sequentially along the conveying direction of the stainless steel strip. The pressure roller support is arranged perpendicular to the conveying direction of the stainless steel strip. A hinge seat is fixed on the pressure roller support. Both ends of the adjusting pressure roller are connected to hinge arms. The hinge arms are rotatably hinged to the hinge seat through a hinge shaft. An adjusting component for adjusting the height of the adjusting pressure roller is connected between the hinge arms and the pressure roller support.

[0003] In existing medical steel strip longitudinal slitting devices, since one end is unwound by an unwinding machine and the other end is wound by a winding machine, the steel strip is prone to breakage during transport due to the difference in unwinding and winding speeds, which affects the slitting efficiency of the steel strip.

Detailed Implementation

[0036] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1-5 This utility model provides a technical solution: a medical steel strip longitudinal slitting and unwinding integrated device, comprising:

[0039] Unwinder 1 is used to unwind the steel strip coil 9 to be slit;

[0040] Slitting machine 2 is used to slit the unwound steel strip of the steel strip coil 9 to be slit;

[0041] Flattening machine 3 is used to flatten the narrow steel strip formed by the cutting machine 2;

[0042] Winding machine 4 is used to wind up the flattened narrow steel strip;

[0043] Among them, a first groove 5 is provided on the ground between the slitting machine 2 and the unwinding machine 1, a first guide roller 51 is provided on the side of the first groove 5 facing the unwinding machine 1, and a first guide plate 52 is provided on the side of the slitting machine 2 facing the first groove 5.

[0044] A second groove 6 is provided on the ground between the slitting machine 2 and the flattening machine 3. A first guide frame 61 is provided on the side of the slitting machine 2 facing the second groove 6, and a second guide plate 62 is provided on the side of the flattening machine 3 facing the second groove 6.

[0045] A first straightening roller 7 is provided on the front side of the slitting machine 2. Several first annular partitions 71 are arranged on the first straightening roller 7 along its own axis. The narrow steel strip extends into the space between two adjacent first annular partitions 71 on the first straightening roller 7. A second straightening roller 8 is provided on the front side of the winding machine 4.

[0046] The first groove 5 on the front side of the slitting machine 2 and the second groove 6 on the front side of the flattening machine 3 allow the unwound steel strip and the slit narrow steel strip to hang down naturally with a certain length reserved, effectively avoiding breakage due to the difference in winding and unwinding speeds, and improving processing quality and efficiency.

[0047] The first straightening roller 7 on the front side of the flattener 3 and the second straightening roller 8 on the front side of the winding machine 4 limit the narrow steel strip during the conveying process, effectively ensuring the flattening and winding quality of the narrow steel strip.

[0048] The first guide frame 61 is equipped with several rollers 611, which are rotatably mounted on the first guide frame 61. The first guide frame 61 has an arc-shaped structure, and the rollers 611 guide the narrow steel strips cut by the slitting machine 2 into the second groove 6.

[0049] The first recess 5 is equipped with guardrails on both sides, which are fixedly installed on the ground. The guardrails effectively prevent people from accidentally entering the first recess 5, avoiding safety risks. The second recess 6 is similarly equipped with guardrails to ensure safety.

[0050] Working principle: When the medical steel strip is longitudinally slit, the steel strip roll 9 to be slit is unwound by the unwinder 1 and guided into the first groove 5 by the first guide roller 51, so that the steel strip hangs down naturally and leaves a certain length. Then the steel strip is guided into the slitting machine 2 by the first guide plate 52 for longitudinal slit. The narrow steel strip formed by the steel strip slit is guided into the second groove 6 by the first guide frame 61 and then guided into the flattening machine 3 by the second guide plate 62 for flattening. Finally, the flattened narrow steel strip is wound up by the winding machine 4.

[0052] This embodiment further improves upon the above embodiment by providing the following technical solution: The slitting machine 2 includes an upper slitting roller 21, a lower slitting roller, an upper pressure plate 22, and a lower pressure plate. The upper slitting roller 21 is positioned corresponding to the lower slitting roller. The steel strip is fed between the upper pressure plate 22 and the lower pressure plate. The upper pressure plate 22 includes several parallel upper plate bodies. The gap width between two adjacent upper plate bodies is greater than the thickness of the upper cutter disc of the upper slitting roller 21. The upper plate bodies are fixedly mounted on a cross support member 221, which is fixedly mounted on the frame of the slitting machine 2. The structure and installation method of the lower pressure plate are the same as those of the upper pressure plate 22.

[0053] When the steel strip is fed into the slitting machine 2, it is clamped between the upper pressure plate 22 and the lower pressure plate, and then longitudinally slitted by the upper slitting roller 21 and the lower slitting roller.

[0054] The slitting machine 2 has symmetrically arranged side guide frames 23 on both sides, and rotatable rollers 231 are installed on the side guide frames 23. The rollers 231 contact the side of the steel strip and guide the steel strip into the slitting machine 2, thereby improving the slitting quality.
