Description

Technical Field

[0001] The utility model relates to an edge correction device, in particular to an edge correction device for winding and releasing a film coil, and belongs to the technical field of film coil winding equipment. Background Art

[0002] Film rolls refer to products that are made by rolling up film materials (such as plastic film, composite film, etc.) in the form of rolls. Such rolls are often used in various fields, such as the packaging industry, the construction industry, agricultural covering, printing and electronics. Film rolls have poor flexural rigidity and are easily misaligned during the winding or unwinding process. Therefore, the position of the film edge needs to be adjusted at any time during the winding or unwinding process.

[0003] A side correction mechanism for retracting and releasing film coils is disclosed in the Chinese patent application publication specification CN203411128U. A photoelectric device monitors the position of the right edge of the film. When it is found that the right edge of the film deviates, an action signal is sent to start the motor to drive the lead screw, thereby adjusting the position of the right side plate on the upper and lower slide rails to the left and right, keeping the right edge of the film in the correct position, and the side correction effect is very good.

[0004] In actual applications, it is found that the device needs to drive the left plate through the cylinder, and the lead screw motor drives the right plate through the lead screw and the lead screw nut to complete the adjustment of the core position. In the process of adjusting the core position, it is necessary to ensure that the cylinder and the lead screw motor are synchronized. The stability of the device for adjusting the core position needs to be improved. At the same time, plastic film has electrostatic properties, which can easily attract and fix dust particles in the production environment, affecting the quality of the film. For this reason, we provide a side correction device for retracting and releasing film rolls. Utility Model Content
