Domestic aluminum-plating transfer gold and silver cards and aluminized transfer laser paperboards are mostly processed using imported equipment. The imported equipment is expensive, and is about US$900,000/machine. Most manufacturers are unable to purchase them. Domestic equipment supply market. The purpose of the development of this equipment is to produce aluminum-plated transfer gold and silver paperboard and aluminum-plated transfer laser paperboard units that have international standards and exceed international standards in order to replace imported equipment, meet user needs, and promote the development of China's packaging industry.
The wet composite process of transferring aluminum-plated film to paper is: transfer aluminized film (second unwinding), web (first unwinding) → sizing → compounding → drying → cooling → winding aluminized film The process of compounding and coloring with paper is: transfer of aluminized film (second unwinding) → sizing → paper (first unwinding) → compounding → coloring → drying → cooling → rewinding of the base layer of direct aluminized paper The surface coating process is: paper (φ1250) (first unwinding) → reticulate coating → drying → rewetting → setting → cooling → reeling Membrane - paper roll (first unwinding) → peeling → film rewinding (carrier film can be reused 8 to 10 times)
Coloring→drying→cooling→selection principle of matching parts for winding machinery According to the product quality, performance, reliability and longevity of domestic and imported parts, based on domestic preference, the principle of selection of electrical components shall take into account domestic electrical components. The use of quality, performance, reliability and life, etc., the key parts of the imported components, other based on domestic production.
Color coating using gravure roller coating method. In coating production, uniformity control of the coating is the most difficult and requires uniform coating under high speed conditions. The device has a variety of adjustment function of the scraper mechanism, can be used for three-dimensional adjustable, and a damping plate, and the pressure roller at both ends of the fine-tuning positioning mechanism, can improve the large-format coating accuracy and uniformity.
The sizing (stripping) gluing mechanism adopts a three-roll sizing mechanism, and its coating amount (coating thickness) can be adjusted by adjusting the gap pressure of the rubber roller (stainless steel roller) and the sizing roller (rubber roller). The φ500mm compound hot-cylinder spoke surface is chrome-plated and mirror-finished. The heat-conducting medium is circulated and heated in the spiral groove of the roller. The heating temperature is controlled by a randomly configured oil die temperature machine. When using the peeling function, remove the steel roller. Replace the aluminum guide roller assembly so that film peeling prevents film scratches.
Due to the flexibility of the carrier film, strict tension control is required. In order to make the coated products reach the mirror surface requirements, and the coating during the production process is free of scratches, strains or crushing, after repeated trials, constant tension unwinding was selected and the tension was controlled by active unwinding. Tapered reducing tension control Large roll diameter center winding and photoelectric servo tracking winding device successfully solves the key technical problem that the surface of the product coating is easily scratched, pulled, and crushed at the time of high speed coating. The peeling is completely clean. , The product meets the mirror requirements.
The drying system is where the energy consumption of the device is highest. In order to make the product completely dry, and the energy consumption is low, a combined drying tunnel was developed after repeated trials. The drying tunnel is an infrared-hot air circulation combined drying tunnel designed according to the mechanism of the coating drying process, so as to avoid that a single hot air oven is prone to surface conjunctiva and the inner layer is not dry, and the single far-infrared drying and drying efficiency can be avoided. The coating is difficult to dry and other defects, is a high-performance drying tunnel.
The unit control mode adopts digital automatic control, and collects and sends on-site data and control commands through the fieldbus (PROFIBUS). The rapid rate reaches 12M; the lower machine adopts Siemens or Omron high-performance PLC, the upper computer adopts Chinese color touch screen and imports. Industrial control machine; unit operation is very intuitive and convenient, the system provides online help, detection, remote monitoring, diagnostics and other functions; temperature control system uses PLD intelligent temperature control.
FTBl800 computer automatic multi-function coating unit has the following structural features:
Driving system: paper unwinding part, film retracting reel part, paper, film reeling part are driven by DC motor; glueing compound (peeling) part, coloring, drying tunnel, cooling traction part are driven by AC variable frequency vector motor, Realize dynamic synchronization control of the whole machine.
Unwinding part: The unwinding device adopts active unwinding for tension control and automatic constant tension control (adjustable). Correct the use of infrared photoelectric hydraulic corrective device to ensure the neat edge.
Winding part: taper tension control Large roll diameter center rewinding using DC motor control, equipped with encoder speed, automatic gap tracking device (adjustable contact pressure) SMC air control tracking system, photoelectric gap detection device, winding tension closed loop control System, automatic tension controller, roll stop automatic alarm device to ensure that the technical indicators have reached the level of imported equipment.
Drying part: divided into five sections of intelligent temperature control, the temperature can be adjusted according to the work needs, and the drying tunnel is opened for each independent point to ensure the drying effect and save energy.
The electrical control part of the whole machine: Each important organization is controlled by the electronic control box of each organization, and it is equipped with a color touch screen man-machine interface operation control system, which is convenient and intuitive.
Other important devices: The retracting reel adopts the air-rising shaft, the blade pressure is pneumatically controlled, and there are functions such as static elimination, automatic metering and line speed display to ensure the product quality.
