Adaptive Rolling Device

technical field

The invention relates to an adaptive coiling aid device, in particular to an adaptive coiling aid device for a winder suitable for cooperating with a lead strip continuous casting machine, and belongs to the technical field of metal non-cutting processing.

Background technique

In recent years, in the battery manufacturing industry, advanced lead strip production equipment has been highly praised by manufacturers for its advantages of high efficiency, energy saving and low pollution, and has become the mainstream equipment for the production of battery grid lead strips. Due to the continuous operation of the lead strip production equipment, in order to meet the requirements for coil storage of lead strip products, at least two winders must be installed behind the lead strip production equipment. The working procedure is: when the first winder is full, it will The lead tape is cut off, so that the lead tape enters the second winding machine for winding operation, and then the fully rolled lead tape on the first winding machine is unloaded, ready to enter the next cycle. In this process, guiding the cut lead strip to enter the next winder is a frequently performed operation step, and it is also a key link affecting the continuous production of the lead strip.

The traditional way of guiding the lead tape is manual winding. The operator presses the head of the lead tape on the rotating main shaft by hand, so that the lead tape and the main shaft rotate synchronously for one revolution, and enters the normal winding process after the head of the lead tape is clamped. Since the feeding of the lead belt and the rotation of the main shaft of the winding machine are both running at high speed, manual winding not only has a low success rate, but also has major safety hazards. Hand pinching accidents occur frequently, and it also restricts the improvement of production efficiency. At present, foreign equipment manufacturers have introduced belt-type coiling aids and multi-roller-type coiling aids in the steel industry. Although the above problems have been solved to a certain extent, the disadvantages of large equipment, complex structures, and fragile The maintenance cost of the parts is relatively high, which limits the popularization and use of the roll-assisting device.

In order to solve the above technical problems, the patent 201220508203.8 discloses an automatic coiling device for a lead belt winder, which mainly includes a pinch roller assembly, a positioning mechanism, and a driving mechanism. The pinch roller assembly presses the take-up drum. The pinch roller assembly of this structure adopts a fixed radian of the pressure roller holder. When working, the driving mechanism drives two radian-fixed pressure roller holders to press against the reel. During use, because the radian of the pressing roller fixing seat is fixed, the radian of the pressing roller fixing seat cannot meet the purpose of winding as the diameter of the lead plate rewound by the rewinding drum increases during the rolling aid.

Contents of the invention

The present invention aims to provide an self-adaptive rolling aid device, the pinch roller assembly of which can self-adaptively adjust the pinch radian as the diameter of the rewinding drum changes during operation.

The present invention adopts the following technical solutions in order to achieve the above object:

The self-adaptive roll-assisting device includes a pinch roller assembly, a positioning mechanism, and a driving mechanism. The pinch roller assembly is arranged on the positioning mechanism, and the driving mechanism drives the pinch roller assembly to compress the winding drum. It is characterized in that: the pinch roller The assembly includes an arc-shaped pinch roller arm and a pinch roller arranged on the arc-shaped pinch roller arm. The arc-shaped pinch roller arm is composed of at least two sections, and each section is hingedly connected. The positioning mechanism includes a pinch arc The compacting structure of the crimping arm of the shaped compacting roller.

In the above technical solution, a tensioning structure is also included. The tensioning structure includes a wrapping belt, a tensioning wheel, and a tensioning drive mechanism. The tensioning wheel is connected to the tensioning drive mechanism. Tensioner.

In the above technical solution, the tension driving mechanism is a hydraulic cylinder or an air cylinder.

In the above technical solution, the positioning mechanism includes a guide rail and a slider, and the slider is arranged on the guide rail.

In the above technical solution, the drive mechanism is connected to the slider and drives the slider to slide on the guide rail, and the hinge of the movable arc-shaped crank arm is installed on the slider through a hinge shaft.

In the above technical solution, the pressing structure is a seat spring or a shrapnel, and the pressing structure is arranged on the slider to press the arc-shaped pressing roller arm.

In the above technical solution, the driving mechanism is a hydraulic cylinder or an air cylinder.

In the above technical solution, a guide angle is provided at the feed inlet of the crank arm of the arc-shaped pressure roller.

In the above technical solution, the pressure roller is arranged along the arc direction of the crank arm of the arc-shaped pressure roller.

The present invention has the following beneficial effects:

At present, the winders on the market can only rewind 2-5 laps and then cannot rewind. In actual work, the first few laps of winding are in the automatic system adjustment stage of the equipment, which is prone to failure. If the general winding and covering mechanism breaks down, it can only stop changing the disc. Restarting the machine again is time-consuming and wasteful. Because the arc-shaped pressing roller crank arm adopted by the present invention is composed of at least two sections, each section is hingedly connected, and it is pressed by a pressing structure. As the diameter becomes larger, the arc of the arc-shaped pinch roller arm also becomes larger adaptively, so that the automatic covering mechanism can wind up more than 50 laps, and the machine will stop working only when it is completely normal.

The driving mechanism is a hydraulic cylinder and an air cylinder. A guide angle is set at the feed inlet of the crank arm of the arc-shaped pressing roller.

After the lead plate exits the rolling mill, it enters the rolling shear to cut off the irregular lead plate. The rolling shear stops working, and the lead plate is sent into the sliding plate through the active bridge. The automatic rewinding introduction system is opened, the introduction slide plate is stretched out, and the cylinder tightens the belt covering frame and wraps it on the rewinding drum. The wrapping frame wraps inward, and the wrapping belt is wrapped on the winding cylinder under pressure to form a circular state, and the tension of the wrapping belt is increased to press the tension cylinder back to its position. The cladding frame is composed of two arc pinch roller arms, three pinch rollers and two sets of springs. Covering the branches on the frame, the curved arm of the pinch roller. There is a turning point in the middle and springs on both sides. When the covering frame hugs the reel tightly, the rollers on both sides first contact the reel under the thrust of the spring. Open up. When the intermediate roller touches the reel, the cylinder pressure is in place. The three rollers on the coating frame are close to the winding drum, and the coating belt is wrapped on the winding drum, and the rotation of the winding drum drives the belt to rotate, and the wrapping belt starts to run and enters the working state. The lead plate enters the wrapping belt through the guide slide, and the lead plate runs along with the reel. The lead plate relies on friction and tension on the winding drum, and automatically winds up after 3-5 turns. The introduction system introduces the slide plate, retracts the original position and exits the work, the cylinder pushes the covering frame to the space on both sides, exits the working state and stands by, and the equipment operates normally.
