Problems solved by technology

The surface of the packaging film of facial tissue often has complex and diverse printing patterns and colors. When the film roll "slips" on the conveyor roller, the film roll is pressed on the conveyor roller, and the film is prone to creases, and the patterns and colors on the film

Embodiment Construction

[0016] Below in conjunction with accompanying drawing, describe in detail as follows:

[0017] figure 1 and figure 2 Among them, the film unwinding servo motor 1 is connected with the film roll 3 through the synchronous belt transmission 2, and the corresponding synchronous belt transmission ratio is 1:1, the film feeding servo motor 15 is connected with the traction pair roller 11 via the synchronous belt transmission 14, and the corresponding synchronous belt The transmission ratio is 1:1, the film winds on the buffer roller group 6 and the fixed roller group 5, passes through the traction pair roller 11, the film pulls the buffer roller group 6 to move up and down, and the buffer roller group 6 drops to the bottom When the film deceleration compensation proximity switch 7 is triggered at the end, when the buffer roller group 6 moves upward, the film stop compensation proximity switch 8 just leaves the film stop compensation proximity switch 8, and the film acceleration co...

Abstract

The invention discloses a high-speed unreeling device for thin film intermittent feed and a control method, belongs to the technical field of automation, and relates to facial tissue pillow type packaging equipment and an electrical control method for thin film coil fast following during thin film quantitative feed. The system comprises a detection unit, a control unit and an executing mechanism,wherein the detection unit comprises a thin film accelerated compensation proximity switch, a thin film compensation stop proximity switch, a thin film decelerated compensation proximity switch, a thin film feed proximity switch and a thin film stop photoelectric switch which are connected with an input end of a servo motion controller; the control unit comprises a touch screen, a servo motion controller, a thin film feed servo driver and a thin film unreeling servo driver; the touch screen and the servo motion controller are electrically connected through a communication bus; the executing mechanism mainly comprises a thin film unreeling servo motor, a thin film feed servo motor, a thin film buffer roller set and a thin film traction roller; the thin film buffer roller set moves up and down through a linear guide rail; and the mechanisms are arranged on a wall board. The device and the control method thereof can guarantee high-speed synchronization of thin film unreeling and thin film feed and prevent the surface of a thin film coil from being damaged and creased.

Description

technical field [0001] The invention relates to the field of automation technology, and relates to facial tissue pillow packaging equipment, that is, an electrical control method for rapid follow-up of film rolls when film is fed quantitatively. Background technique [0002] In the technological process of facial tissue packaging equipment, film feeding and film unwinding are involved. The film is usually fed intermittently, that is, one sheet is fed, stopped, and another sheet is fed. In this feeding mode, the film unwinding requires fast start and fast stop. The traditional film unwinding control method is: the film roll is tightly pressed on the conveying roller, the film passes through the conveying roller, bypasses the tension device, and is sent to the feeding mechanism, and the conveying roller and the feeding mechanism are driven by the same motor. When the film feeding is required, the motor drives the film feeding mechanism and the conveying roller to run at the ...
