Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a slitting machine with noise reduction and protection functions. Background Art

[0002] Slitting machine, also known as slitting machine, stripping machine or slitting machine, is a kind of equipment widely used in the metal processing industry. It is mainly used to cut wide metal coils (such as steel plates, aluminum plates, stainless steel plates, etc.) into several narrower coils along their length direction (i.e. longitudinal direction). Slitting machines are widely used in transformers, motors, home appliances, automobiles, building materials, packaging and other industries to meet the needs of metal strips of different widths. When the slitting machine is processing, the friction between the high-speed rotating blade and the metal during the cutting process will generate noise. If the human body is in a high-noise environment for a long time, it will suffer greater damage, and it is easy to have tinnitus, hearing loss and other problems, and even deafness in severe cases. Therefore, it is necessary to effectively control and deal with the noise generated by the slitting machine.

[0003] When some existing longitudinal shears are in use, the noise reduction mechanism arranged on them is often fixed, which makes it inconvenient to adjust the position of the noise reduction mechanism. There is a gap between the noise reduction mechanism and the metal strip, which causes the noise reduction cover to be unable to completely cover the noise source. Part of the noise can leak out through the gap, which is not conducive to improving the noise reduction effect.

[0004] For example, the publication number CN212761425U discloses a longitudinal shearing machine with a waste collection structure. The longitudinal shearing machine of this patent is equipped with a noise reduction cover and sound-absorbing cotton. The noise reduction cover is used to cover the processing and slitting, and the sound-absorbing cotton is used to absorb the noise generated during the processing, thereby greatly improving the noise reduction and environmental protection of the mechanism.

[0005] Although the slitting machine of the patent is equipped with a noise reduction cover, the noise reduction cover is fixedly set on the support plate, which means that it cannot be adjusted according to the needs of the metal sheet or operation. Since the size of the metal sheet may vary, the fixed noise reduction cover may not be able to completely cover the noise source, causing some noise to leak out through the gap, which is not conducive to improving the noise reduction effect.

[0006] Therefore, it is necessary to invent a slitting machine with noise reduction and protection function to solve the above problems. Utility Model Content

[0007] The utility model aims to provide a slitting machine with noise reduction and protection function to solve the above-mentioned technical problems.

[0009] The design of the electric push rod and loading axis allows the soundproof cover and shear mechanism to be flexibly raised and lowered to accommodate metal strips of different sizes; the combination of telescopic rods and springs ensures the stability and safety of the soundproof cover during the lifting process.

[0010] Preferably, a sound-absorbing cotton layer is fixedly connected to the inner wall of the soundproof cover, an observation window is opened on the front side of the soundproof cover, and a transparent PC soundproof board is installed inside the observation window.

[0011] The sound-absorbing cotton layer enhances the sound insulation effect, while the observation window is designed with a transparent PC sound insulation board, so that the operator can observe the shearing process without opening the sound insulation cover.

[0012] Preferably, rollers are installed at the four corners of the bottom of the sound insulation cover, and a sound-absorbing cotton strip is fixedly connected to the bottom edge of the sound insulation cover.

[0013] The rollers allow the metal strip to move smoothly at the bottom of the soundproof cover, while the sound-absorbing cotton strips further reduce noise leakage between the soundproof cover and the metal strip, thereby improving the noise reduction effect.

[0014] Preferably, the shearing mechanism comprises a suspension frame, the suspension frame is fixedly connected to the bottom of the loading shaft, and the bottom of the suspension frame is rotatably connected to a cutting roller.

[0015] The suspension frame serves as a fixed basis for the shearing mechanism, ensuring the stable operation of the cutting roller.

[0016] Preferably, a No. 1 motor is installed on one side of the suspension frame, and one end of the cutting roller is drivingly connected to the No. 1 motor.

[0017] The cutting roller is driven to rotate by the No. 1 motor to realize the automatic cutting operation.

[0018] Preferably, limit guide mechanisms are provided on both sides of the top of the workbench, and the two limit guide mechanisms are symmetrically distributed about the gantry bracket.

[0019] Through two symmetrically distributed limiting guide mechanisms, the direction of the metal strip can be accurately controlled to prevent deviation during the shearing process, thereby ensuring the shearing quality.

[0020] Preferably, the limiting guide mechanism includes a bidirectional lead screw, a slide groove is provided on the top of the workbench, the bidirectional lead screw is rotatably connected to the inside of the slide groove, a No. 2 motor is installed on one side of the workbench, and one end of the bidirectional lead screw is transmission-connected to the No. 2 motor.

[0021] The bidirectional lead screw can be driven to rotate by the No. 2 motor.

[0022] Preferably, two loading blocks are slidably connected inside the slide slot, and both loading blocks are connected to the bidirectional lead screw transmission. The top end of the loading block extends to the outside of the slide slot and is fixedly connected to a mounting frame, and a sliding roller is rotatably connected to one side of the mounting frame.

[0023] The two loading blocks are driven while the bidirectional lead screw rotates, so that the two loading blocks can move toward or away from each other, thereby quickly adjusting the distance between the two sliding rollers to accommodate metal strips of different widths, thereby improving the adaptability and working efficiency of the equipment.

[0024] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0025] 1. By equipping the top of the shearing mechanism with a soundproof cover, the soundproof cover and the sound-absorbing cotton layer inside it can limit the spread of noise. In addition, the adjustable design of the soundproof cover and the shearing mechanism enables the soundproof cover to maintain an appropriate gap with metal strips of different sizes, and the sound-absorbing cotton strips at the bottom of the soundproof cover can fill the gap to further prevent noise leakage, which is conducive to improving the noise reduction effect;

[0026] 2. By driving the bidirectional lead screw through the No. 2 motor, the movement of the two loading blocks and the mounting frame is controlled, so that the distance between the sliding rollers can be adjusted quickly and accurately to accommodate metal strips of different widths. This design not only simplifies the positioning and fixing process of the metal strip, but also ensures that the metal strip can move forward steadily during the cutting process, avoiding cutting accuracy problems caused by shaking or offset.

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual Figure 1-5 When using the utility model, firstly, the metal strip to be cut is placed on the workbench 1, and is passed between the sliding rollers 23 of the two limit guide mechanisms 17, and the second motor 20 is started, and the loading block 21 and the mounting frame 22 are driven to move by the rotation of the bidirectional lead screw 18, so as to adjust the distance between the two sliding rollers 23 to match the width of the metal strip, so as to ensure that the metal strip can move forward stably during the cutting process;

[0039] Before preparing for cutting, the soundproof cover 4 is first slowly lowered by the electric push rod 5, and the roller 12 at the bottom of the soundproof cover 4 will first contact the metal strip. As the electric push rod 5 continues to push, the loading shaft 7 gradually sinks into the inside of the soundproof cover 4, driving the shearing mechanism 3 to descend together, until the cutting roller 15 of the shearing mechanism 3 contacts the metal strip, and then the No. 1 motor 16 is started, and the cutting roller 15 is rotated through transmission to start cutting the metal strip;

[0042] Through the transparent PC sound insulation board 11 on the front side of the sound insulation cover 4, the cutting process can be clearly observed. If any abnormality is found, the machine can be stopped immediately for adjustment.
