In daily operations, the slitting machine constantly faces sheets of material, and its primary task is to provide complete cutting data for the sheets. Throughout the processing, the roller components bear the main part of the operation, so during the operation of the slitting machine, it is common to encounter reasons for the slow rolling of the rollers. If the rollers on the slitting machine are not flexible, there must be some reason affecting them.
Reasons and Solutions for Slow Rotation of Slitting Machine Rollers
In daily operations,Slitting Machinefacing the sheets all day, its primary job is to inform the complete cutting of the sheets into corresponding scale data. Throughout the processing, the roller components bear the main part of the operation, so during theSlitting Machineoperation, it is common to encounter reasons for slow roller rotation.
The rollers on the slitting machine are not flexible, and there must be some reasons affecting this. For example, the thickness of the processed sheet has exceeded the rated size of the slitting machine, causing the rollers to get stuck. Therefore, if you want to encounter such data in the future, it must be handled first before performing longitudinal cutting. On the other hand, if the drive chain on the slitting machine's drive device falls off or breaks, the same problem will occur. In this case, the chain needs to be adjusted from the beginning or replaced directly.
Another possibility is that the motor has issues, such as poor contact of its start button, malfunctioning contactor, unpowered circuits, or burning out, etc. All these can lead to the rollers of the slitting machine not rotating.
Processing Capacity and Maintenance of Slitting Machine Blades
The slitting machine uses metal coils for rewinding, leveling, and cutting, and can process various materials, such as coated stainless steel surfaces, as well as cold-rolled and hot-rolled carbon steel. The automation level of the slitting machine is very high, and the operation is very simple and convenient. It can also be used for longitudinal cutting of metal strips, with high cutting quality.
Therefore, not only is the material utilization rate high, but the efficiency of material use is also high, avoiding waste and saving costs for enterprises and resources for society. The cutting speed of the slitting machine is also steplessly adjustable, allowing it to longitudinally cut metal materials, then cut them, and roll the cut materials into rolls.
Vertical Slitting MachineNo two different types of materials are allowed on the blade, and multiple layers cannot overlap during cutting. The blade should not remain on the metal sheet or tabletop during feeding, and fingers should be at least 200mm away from the opening during cutting.
We should have dedicated personnel to oversee the blades of the slitting machine. Operators should fully understand the performance and structure of the machine tool. When overloaded, they should not use the blades of the slitting machine and should not harden high carbon steel, alloy steel, high-speed steel, etc., ensuring that the blade edges are sharp. If they become dull, they should be promptly sharpened or replaced.
After rough cutting of the raw materials for the slitting machine, they reach the buffer pit. After adjustment in the buffer pit, the straight edge is determined on the tabletop according to the product's set dimensions, and then cut off with a hydraulic kopis, automatically falling onto the discharge tabletop of the slitting straightening machine. The rough part must track the position of the raw materials in the pit to adjust the speed, and the product size and line speed are set directly on the touchscreen.
Considering system reasons,Slitting Machinethe inverter uses multi-speed PLC control, with four photoelectric sensors installed in the pit to detect the position of the raw materials, then sends the position signal to the PLC, which controls the speed of the inverter. When the position of the raw materials is fed back to the specified position, the inverter operates at high, medium, and low speeds, then stops.
