Description

A pressure roller automatic retraction adjustment mechanism of a winder

technical field

The utility model relates to the technical field of winding machines, in particular to an automatic retraction adjustment mechanism of a pressure roller of a winding machine.

Background technique

The winder of the gravure printing unit needs a guide roller to guide the paper during winding. As the diameter of the paper roll expands, the pressure roller needs to be continuously retracted so that it is always guided close to the paper roll without applying pressure to the paper roll. The retraction of the pressure roller is realized by the cylinder driving the guide roller frame to swing back, and the degree of expansion and contraction of the cylinder determines the swing degree of the guide roller frame. At present, the expansion and contraction of the cylinder is determined by the controller through the motor speed and rotation time. Every time the motor rotates, a layer of paper is rolled up. When the motor speed (even if the motor speed changes regularly) and the time are determined, for For the same paper, the change of its diameter is theoretically known, and the controller can control the cylinder to complete the process from the ejected state to the contracted state within a certain period of time.

In the actual production process, because the installation of the pressure roller and the winding shaft cannot be completely parallel, the sudden change of the motor current, and the vibration of the machine itself, the retraction of the pressure roller often cannot completely match the diameter change of the paper roll, which will The pressure roller directly presses on the paper roll, resulting in inconsistent paper winding pressure, uneven edges of the paper roll, severe core wrinkle, and increased reject rate.

Utility model content

The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology, and to provide an automatic retraction adjustment mechanism for the pressure roller of the winder. The pressure roller can quickly respond to the diameter change of the paper roll, thereby basically realizing maintaining The state of guiding close to the roll without exerting pressure on the roll.

The technical purpose of the utility model is achieved in that:

A pressure roller automatic retraction adjustment mechanism of a winder, characterized in that it includes a swing frame, a pair of guide rollers installed on the swing frame, and a pressure roller mounted on the free end of the swing frame, the hinged end of the swing frame passes through the pin The shaft is hinged between the two wall panels of the machine base, and the two sides of the swing frame are respectively connected with the ejector rod of a cylinder through connecting blocks. A distance sensor is arranged below, and the distance sensor, the solenoid valve of the air cylinder and the driving motor of the winding shaft are all connected with the controller of the gravure printing machine.

The axis of the distance sensor is arranged along the diameter direction of the winding shaft.

Compared with the prior art, the utility model has the following advantages: the utility model keeps the distance sensor perpendicular to the paper surface, monitors the thickness change of the paper roll at any time, adjusts the retraction degree of the cylinder accordingly, and basically realizes it in the whole winding process Keeping close to the paper roll for guidance but not exerting pressure on the paper roll, the overall structure is simple and easy to use.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing of description, the utility model is further described.

As shown in FIG. 1 , a pressure roller automatic retraction adjustment mechanism of a winder includes a swing frame 4 , a pair of guide rollers mounted on the swing frame and a pressure roller 6 mounted on the free end of the swing frame. The pressing roller is above the winding shaft and kept parallel with the winding shaft. The hinged end of the swing frame is hinged between the two wall panels 2 of the machine base 1 through the pin shaft 3, and the two sides of the swing frame are respectively connected with the ejector rod of a cylinder 9 through the connecting block 10, and the cylinder body of the cylinder is hinged on the machine base , The rewinding shaft 8 is installed on the top of the machine base, the distance sensor is arranged below the rewinding shaft, and the distance sensor, the solenoid valve of the cylinder and the driving motor of the rewinding shaft are all connected with the controller of the gravure printing machine. The axis of the distance sensor is arranged along the diameter direction of the winding shaft.

The working principle of the utility model is: the rewinding shaft 8 rotates under the drive of the drive motor, and the traction paper 5 is rewound on the rewinding shaft. As time increases, the paper is wound layer by layer, and the diameter of the paper roll 7 is constantly changing. Large, the distance from the distance sensor is getting closer and closer, the distance sensor keeps sending distance signals to the controller, and the controller adjusts the intake and exhaust of the cylinder in real time according to the distance signal, and adjusts the speed of the cylinder to keep the swing frame close The paper roll is guided but does not exert pressure on the paper roll. The winding process is completed by the winding shaft, and the paper winding is stable.

The above descriptions are only preferred embodiments of the present utility model, and for those skilled in the art, the present utility model can have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
