The uncoiling mechanism is a crucial part of the uncoiler straightener feeder machine, and it has undergone significant improvements compared to the conventional uncoiling machine. The uncoiling part of the machine is equipped with a material support device, a material pressure device, and a clamping device, which work in tandem to ensure efficient and reliable uncoiling.
1.Material Support Device and Material Pressure Device
The material support device is positioned below the rolled material during the uncoiling process and helps with feeding. It provides additional support to the material to prevent it from sagging and helps maintain a consistent feed rate. The material pressure device works in conjunction with the uncoiling device to prevent the rolled material from loosening during the uncoiling process.
2.Improved Uncoiling Device
The uncoiling device has been improved from the traditional hand-operated expanding mode to an oil-pressure expanding mode. The rolled material cylinder adopts a wedge-shaped slide block structure that horizontally spans the frame of the uncoiling machine. The middle part of the cylinder is connected to a rotary joint that connects to the oil-pressure device. The four wedge-shaped slide blocks are driven to move axially by the push rod of the oil-pressure device.
3.Arc-Shaped Tile Plate Movement
The four arc-shaped tile plates are attached to the outer edge of the wedge-shaped slide blocks. These plates have connecting blocks set axially on the inside, which are connected to the wedge-shaped slide blocks through a connecting rod. The connecting block extends to the inner end of the arc-shaped tile plate and passes through a radial strip hole that faces the limit stop plate. The connecting block has a limit stop slide block on either side that prevents it from moving axially along the connecting rod.
The push rod of the oil-pressure device drives the end cap and the four wedge-shaped slide blocks to move axially, which in turn pulls the arc-shaped tile plate through the connecting rod. Since the connecting blocks on the inside of the arc-shaped tile plate are restricted by the limit stop slide block and limit stop plate, they cannot move axially, but can only move radially along the strip hole on the limit stop plate. This achieves the radial movement of the arc-shaped tile plate, which is used to tighten and loosen the rolled material.
The side of the uncoiling frame of the uncoiler straightener feeder machine is equipped with a clamping device. The clamping device includes a reliable oil cylinder and a clamping shaft driven by a reliable crank. The clamping shaft has two vertically arranged clamping rollers with adjustable spacing. This clamping device prevents the rolled material cylinder from moving axially along the spindle, ensuring the stable operation of the whole machine.
5.Induction Switch and Pneumatic Braking System
The uncoiling machine frame is also equipped with an induction switch and a pneumatic braking system for controlling the operation of the power device. The pneumatic braking system includes a brake disc mounted on the spindle and a pneumatic brake clamp. When the leveling and feeding part of the uncoiler straightener feeder machine stops running, a control signal is sent to the induction switch, which disconnects the power supply to the power device, causing it to stop supplying power. Due to inertia, the spindle will continue to rotate. At this time, the pneumatic braking system is started, and the brake clamp clamps the brake disc, producing friction force, which acts as a brake to rapidly stop the spindle from rotating.
The uncoiling part of the uncoiler straightener feeder machine is an essential component that has undergone significant improvements. It utilizes an oil-pressure expanding method and the wedge-shaped slide block structure drives the arc-shaped tile plate movement, which ensures low resistance, low wear, low failure rate, and a long service life. The addition of a material support device, material pressure device, and clamping device enhances the efficiency and reliability of the uncoiling process, while the induction switch and pneumatic braking system ensure the safety of the machine.
In summary, the uncoiling mechanism of the uncoiler straightener feeder machine is a highly advanced system that enables efficient and reliable uncoiling of rolled materials. Its improved design, with the use of an oil-pressure expanding method and wedge-shaped slide block structure, offers low resistance, low wear, and a long service life. The addition of a material support device, material pressure device, and clamping device ensures stable and precise uncoiling, while the induction switch and pneumatic braking system provide safety measures for the machine. With these advanced features, the uncoiling mechanism of the uncoiler straightener feeder machine sets a high standard for the industry, ensuring superior performance and reliability in the uncoiling process.
