Description

Friction Tension Winder

technical field

The utility model relates to a friction tension winding machine.

Background technique

When slitting high-end copper strips such as electroplating materials, the requirements for controlling scratches on the surface of the strip are relatively high. Generally, the slitting line tension control method has a large scratch on the surface of the strip, and the initial investment cost of the basic business is very high. Commonly used tension control methods for copper strip slitting lines are: 1) belt tension machine control method. 2) Vacuum roll control mode.

The reel of the traditional slitting line is an expandable structure. When the strip is rewound, it is glued to the paper sleeve of the reel of the reel or the strip is clamped by the jaws. When the line is running, the strip rotates synchronously with the reel. The belt tensioner uses the clamping force to generate friction between the strip and the felt or the belt, thereby controlling the winding tension. The vacuum roll uses vacuum suction before the winder to generate friction between the strip and the felt on the vacuum roll to control the winding tension. Both of these control methods need to dig pits in the workshop to store the strips to adjust the winding speed. When the production line is running, only the strips have tension between the belt tensioner or the vacuum roller and the winder, and the rest of the strips have no tension. . When the strip is cut and slit by the slitting machine, it is necessary to use a pressure plate or a rubber ring to press the strip to prevent the strip from being deformed and deviating in the slitting machine, thereby affecting the cutting quality.

The generation of winding tension in the above two tension control methods requires contact with the strip to generate friction, which makes the surface of the copper strip prone to large scratches or indentations, which cannot be satisfied when slitting high-end strips such as electroplating materials. product requirement. In order to solve this problem, it is necessary to change the tension control method when the strip is slitting to reduce the surface friction of the strip, so as to achieve higher surface quality requirements.

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a friction tension winder.

The purpose of this utility model is achieved through the following technical solutions:

The friction tension winder is characterized in that: an uncoiler, a correction roller, a slitting machine and a winder are sequentially arranged along the strip conveying direction, and the winder includes a winding shaft, a winding disc and a pull rod, and the winding shaft There is an axial through hole in the center of the center, and a spacer and a radial keyway are provided on its outer edge. Friction plates are provided on both sides of the reel, and the friction plates are placed in the radial keyway. A pull rod is installed in the axial through hole, and a pressure plate is installed on the shaft end of the pull rod. The inner surface of the pressure plate is pressed against the spacer sleeve, and the movement of the pull rod makes the pressure plate press the spacer sleeve.

Furthermore, in the friction tension winder mentioned above, a front tensioner is provided between the uncoiler and the correction roller.

Furthermore, in the above-mentioned friction tension winder, a rear tensioner is provided between the slitting machine and the winder.

Furthermore, in the above-mentioned friction tension winder, one end of the pull rod is connected with the piston rod of the air cylinder.

Still further, in the above-mentioned friction tension winder, wherein, the pressure plate is fixed to the shaft end of the pull rod through a lock nut.

The substantive features and progress of the technical solution of the utility model are mainly reflected in:

① It can avoid scratches on the surface of the strip, and it takes up less space than ordinary slitting lines. There is no need to dig a loop hole for the foundation of the plant, saving plant space and construction costs. And other high-end strip production requirements.

② When the production line is running, the speed is controlled by the uncoiler, and the tension is controlled by the winder; in order to maintain stable tension and speed, the winder uses a reel to rewind; The sliding friction of the disc and the winding shaft produces strip tension, which avoids scratches on the strip. When the production line is running, the strip runs with tension on the whole line. When the strip is slitting in the slitting machine, because the strip has a tensile force, the strip is not easy to wrinkle and deviate during cutting and slitting, so there is no need in the slitting machine. Increase the pressure plate, thereby further reducing the surface abrasion of the strip.

③When the production line is working, the cylinder drives the pull rod to move, so that the pressure plate is pressed against the spacer. When the rewinding shaft rotates, friction is generated between the friction plate and the rewinding reel, between the rewinding reel and the rewinding shaft, which can be adjusted by controlling the pressure of the cylinder Pressure on the side of the platen, and then the tension is controlled by changing the friction. In order to keep the tension of the winding strip constant, the adjustment of the cylinder pressure is changed in real time with the change of the coil diameter, and is automatically controlled by electricity. When the production line is running, the line speed of the winder is faster than that of the production line, so as to ensure that the relative sliding between the winding disc and the friction plate is always maintained to ensure the stability of the strip tension, and each strip winding disc is relatively independent , can effectively eliminate the length difference between the single materials after cutting, so that the tension of each strip is balanced.

As shown in Figure 2, the winder includes a winding shaft 601, a winding disc 606 and a pull rod 603. The center of the winding shaft 601 has an axial through hole, and its outer edge is provided with a spacer 602 and has a radial keyway. Both sides of the reel 606 are provided with friction plates 607, and the friction plates 607 are placed in radial key grooves. A pull rod 603 is installed in the axial through hole of the winding shaft, and a pressure plate 604 is installed on the shaft end of the pull rod 603. The pressure plate 604 passes through The locking nut 605 is fixed, the inner surface of the pressure plate 604 is pressed against the spacer 602 , one end of the pull rod 603 is connected with the piston rod of the cylinder, and the movement of the pull rod 603 makes the pressure plate 604 compress the spacer 602 .

Wherein, the winding reel 606 can rotate freely on the rewinding shaft 601, and there are friction sheets 607 on both sides of the rewinding reel 606, and the friction sheets 607 rotate synchronously with the rewinding shaft 601 through the key grooves on the rewinding shaft. When the production line is working, the cylinder drives the pull rod 603 to move, so that the pressure plate 604 presses the spacer 602, and when the rewinding shaft 601 rotates, friction is generated between the friction plate 607 and the reel 606, and between the reel 606 and the reel 601. The side pressure of the pressure plate 604 is adjusted by controlling the pressure of the cylinder, and then the tension is controlled by changing the friction.

In order to maintain a stable tension and speed, the winder 6 adopts a winding reel for winding. The reel 606 and the reel shaft 601 can slide relative to each other, and the strip tension is generated by the sliding friction between the reel 606 and the reel shaft 601 , thus avoiding scratches on the tape A. When the production line is running, the strip A runs with tension on the whole line. When the strip is slit in the slitting machine 4, because the strip has a tensile force, the strip is not easy to wrinkle and deviate during cutting and slitting. Therefore, the slitting machine 4 There is no need to increase the pressure plate inside, so as to further reduce the abrasion of the strip surface.
