Equipped with ultra-large-scale integrated circuits and controlled by a microcomputer with a Chinese touch screen for human-machine interaction, this touch screen labeling machine allows operators to easily input various data through the touch screen and fully control the operation of the labeling machine after startup; Model LT-330 PLC-controlled horizontal round bottle self-adhesive labeling machine is an upgraded product of our company, featuring a simple and reasonable structure and easy operation, its production capacity can be steplessly adjusted according to the specifications and characteristics of bottles and labels, and it has strong adaptability to bottles, which can achieve satisfactory labeling results on glass and plastic bottles of various specifications for food, pharmaceutical, cosmetic and other industries with either transparent or opaque self-adhesive labels, its main specifications and technical parameters are as follows: labeling speed: 80-200 bottles per minute (depending on labeled objects and label length), applicable bottle outer diameter: φ10-30mm, applicable bottle height: 20-100mm, label size: length 10-100mm, height 20-80mm, power: 600W, voltage: 220V 50/60Hz, overall dimension: 18008001500mm, weight: 250Kg, and the machine is mainly composed of feeding unit, conveying unit, machine frame, label unwinding unit, labeling head and electric control part. The equipment controller consists of a microcomputer control section (touch screen, system control board and signal interface board), a signal sensing section (diffuse reflection photoelectric sensor and through-beam photoelectric sensor), a stepper motor and drive section (stepper motor and stepper motor driver), a voltage-stabilized power supply section (power transformer and voltage-stabilized power supply board) and other components. The system adopts ultra-large-scale integrated circuits and high-quality imported components, delivering fast labeling speed, high reliability and excellent stability. Developed on the basis of traditional liquid crystal controllers, this controller features an enlarged human-machine interface as well as added graphic display and Chinese message prompt functions compared with previous liquid crystal controllers, enabling convenient, efficient and more humanized control operations. In particular, it adds digital control for speed-regulating motors, allowing operators to adjust, start and stop bottle separating speed, label winding speed and bottle conveying speed via the controller operation interface, thus truly realizing the goal of controlling the overall mechanical operation through the controller.
