Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a dust removal mechanism for high-speed slitting machines. Background Art

[0002] A slitting machine is a mechanical device that cuts wide paper, mica tape or film into multiple narrow materials. It is commonly used for slitting non-woven fabrics, mica tape, paper, insulation materials and various film materials. Material debris and dust are inevitable when the slitting machine is processing. The accumulation of material debris and dust at the slitting machine will affect the working environment. In addition, material debris and dust are flammable and pose a safety hazard, so a corresponding dust removal mechanism is required to collect the material debris and dust.

[0003] After searching, the Chinese patent with the existing application number CN202222313593.X discloses a dust removal mechanism for a high-speed slitting machine. By starting the rotating motor, the first rotating shaft rotates, thereby rotating the first half gear, and moving the double-sided toothed plates outward. At the same time, the rotation of the first rotating shaft drives the belt assembly to move, and then the second rotating shaft rotates synchronously, so that the second half gear rotates, and then the double-sided toothed plates move inward, that is, the double-sided toothed plates move back and forth inward and outward, so that the movable frame drives the dust collection hood to move back and forth, which is beneficial to increase the dust collection range, thereby performing comprehensive dust collection on the side of the cutting blade, which can help prevent the plastic waste generated by cutting from splashing everywhere, reduce the pollution of the waste to the surrounding environment, reduce the absorption of waste by the staff, and at the same time help improve the safety of the working environment.

[0004] The above technical solution has the following defects: although the dust removal mechanism of such a high-speed slitting machine can collect the waste chips generated by cutting through a movable dust suction hood, during actual use, the cutting tool cuts the material, and the material debris and dust will splash out from both sides. If it is collected only on one side, the dust removal effect is poor. In order to further ensure the dust removal effect and perform dust removal on multiple cutting points, a dust removal mechanism for a high-speed slitting machine is proposed. A wide dust removal hopper is provided in the slitting machine, which can be fitted with the cutting points of multiple cutting rollers, so that the cut debris dust can be effectively absorbed and collected, and a debris dust collection box is provided to facilitate the collection and treatment of the debris dust so that it can be discharged uniformly.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the dust hopper is installed at the bottom of the slitting roller, and the length of the dust hopper is adapted to the length of the slitting roller, so that the dust hopper can extract and collect the debris and dust generated by cutting at the bottom, thereby achieving a better dust removal effect.

[0011] Furthermore, the protective net is configured as an arc-shaped structure, and the arc-shaped protective net can be more fully close to the cutting part of the fabric, thereby collecting the generated debris and dust.

[0012] Furthermore, the dust collecting box is fixedly installed with an air bag, the air bag is fixedly connected to an electromagnetic pulse valve, and the electromagnetic pulse valve is fixedly connected to a blow pipe.

[0016] The utility model provides a dust removal mechanism for a high-speed slitting machine, which has the following advantages:

[0017] 1. The fabric is fed into the slitting machine from the coil feeder, bent by multiple guide rollers, slit by the slitting rollers, and then wound up on two winding rollers. The hydraulic cylinder in the load-bearing bracket is activated to drive the mounting bracket to press down, and the rotating motor is activated to rotate the slitting rollers to drive the slitting disc to rotate, so that the fabric passing at high speed can be quickly slit;

[0018] 2. Start the exhaust fan during slitting. The exhaust fan can extract the air in the dust box so that the debris dust generated by the slitting roller can be extracted and collected by the dust hopper. The protective net can prevent large debris from being sucked in. The debris dust is transmitted to the dust box through the dust hopper. The dust filter in the filter frame can intercept the debris dust and prevent it from entering the exhaust fan. Start the electromagnetic pulse valve to spray the air at the air bag from the injection pipe, so that the debris dust intercepted in the dust filter can be blown to the bottom of the inner wall of the dust box. Open the discharge valve to discharge the collected debris dust.
