  • Application
    The machine is the fully automatic shunt winding and cutting machine with foil-type materials. It is researched by Zhangjiagang Fineness Aluminum Foil Co., Ltd. in the latest time and applied to the shunt winding processing work of the soft foil materials.

    Because of this machine adopts advanced PLC as control system, realize the complete machine run, automatic feeding and baiting; aluminum foil cut long settings and display; stepless speed adjusting and display of the aluminum foil run line speed; shutoff control; fault auto-diagnosis etc. function. Aluminum foil transmit, the squirrel-cage rotation is adopt inverter and servo motor driver. Thus this machine has simple operation, safe and reliable, high automation degree and the highest production efficiency.
  • Main structure
    HAFA850 model household aluminum foil cutting machine, The major components of decoiling department, roller and foil materials traction system; rotary automatic received foil system, tube feeding system, winding system, ultraviolet disinfection system, due to its reasonable layout, thus complete machine is compact structure, beautiful appearance. Each part of the function, structural features and adjustment as follows:

    Decoiling department:
    The mechanism for centering and horizontal adjustment is established in this part to rotate the adjustable hand wheel in different mechanisms for the purpose of centering the volume and paralleling the volume axis and post roller axis. The stroke range of both centering and horizontal adjustment is ±20mm.

    Stretch roller:

    A group of post rollers and several stretching processes are established from the rolling-up to the traction roller so as to eliminate the tension pulsation and wrinkling phenomenon when the volume is out-of-round and ensure the flat and wrinkling free aluminum foil when the foil materials enters the winding parts.

    Foil material traction system:

    The traction system is the main power part for foil material transmission while the driving adopts AC frequency control inductor motor. The transmission utilizes the chain mode to ensure it is carried out on a steady and gapless basis. The rubber pressing roller action is in pneumatic compression mode. The height of the stop screw under the sliding blocks on both ends is adjusted and the size of the pressing force can be adjusted arbitrarily.

    Rotary automatic received foil system:

    The pneumatic sealing rotation squirrel-cage structure is adopted in this part, finishing rolling up, handover, winding, crosscut and place rolling down and other actions automatically. The system adopts imported electromagnetic clutch to control the tension and the slip torque number can be set arbitrarily. PLC is controlled automatically and the winding speed can be arbitrarily established and displayed in the operation panel and within the range of ≤ 50 meter/minute according to the production requirements. The cylinder electromagnetic valve is the products from Taiwan. Since the part is the core of the whole machine, it demands a high precision of processing and assembly. When the user carries out production, it is necessary to change the corresponding revolving knife according to the length of the paper core and then adjust the spacing of the flange rotary table along the direction of the squirrel-cage axis to make the upper and lower tube smooth. If the internal diameter of the die changes, professional maintenance personnel shall be sent to change the cone roof on the two flanges rotary tables accordingly.

    Tube feeding system:

    The automatic paper tube core, sizing, tube-sending positioning and other functions are established on the structure. The loading box of the paper tube is in loading mechanism of the slope electric vibration type to ensure smooth loading of in consequence. It is active type on both sides with the width of the ring offset 30-35mm. As for the adjustment of the spacing among the rings, the axial direction can be used to adjust three rubber rollers to adjust the spacing. The adjusted spacing shall be based on the spacing of two squirrel-cage flange tables. The sizing mechanism is realized by adopting the imprinted ring offset. The spring pressure on both ends of the rubber rollers shall be regulated to control the thickness of the gluing layer.

    Winding system:

    The winding system is divided into slope material receiving and stainless steel chain with take-up table for material receiving. After the squirrel-cage carries out blanking, it will rolls along the slope and finishes the winding of the material tail. When the revolving knife carries out action, the volume will accurately fall into the take-up table in the stainless steel chain by linkage mechanism. Finally, it will be brought out by the belt of the chain. The winding driving is in type of imported AC servo motor and the interval motion of which is controlled by PLC. Meanwhile, it will drive the rolling up driving and squirrel-cage which carry out synchronized motion to rotate on an interval basis.

    Ultraviolet disinfection system

    Ultraviolet disinfection system is established between the spring off-roller and traction roller to carry out ultraviolet disinfection to the positive and negative side of the aluminum foil at the same time to guarantee the health requirements of the food and package etc. When pulling through material or repairing the ultraviolet lamps, it is only necessary to open the front door of the disinfection box and it shall be closed when working. The number of the ultraviolet lamps is 2 in total with 20W for each one.

    When the adjustment interrupt cylinders, open the window of protective cover.
  • Operating
    1. Readiness for running:

    First, check the power voltage , switch on the main power, in turn switch on the frequency power switch, servo power switch and control parts power switch. Inverter, servo drive shows standby. Microcomputer controller to display name of our company and contact way.

    2. Automatic tube feeding:

    The servo motor will drive the squirrel-cage to rotate by pressing the upper tube electric button beside the lower frame. The paper tube can be clipped on the squirrel-cage automatically (note: the action works when the traction foil-feeding stops)

    3. Setting of the cutting length:

    The establishment of the cutting length means the length settings needed by each volume ofaluminum foil.
    The microcomputer controller researched by our company in the latest is able to set length within the range of <3-300 meters=""> with simple and visual setting process. The setting method is as follows:(if it’s siemens touch screen panel,Please refer to extra instruction)

    Press+ to introduce other interface and press + again to enter the working interface. Press S to enter the fixed-length setting and press S again until the number flashes. Press M to move the digit and press + --to modify number. Press S to keep setting and press + to exit. Press— to enter the working interface.

    4.Traction separation, traction stitching:

    The traction stitching and traction separation button on the operation panel of the electric box are used for controlling the separation and stitching of the traction roller of the aluminum foil.

    5. Operation:

    Open the disinfection lamp and start the gluing motor. Press the operation button the machine enters the operation working status.

    The traction motor starts foil delivery and the speed knob shall be regulated to make the speed of the traction foil feeding reach the preset speed.

    The microcomputer controller finishes tube feeding and foil break motion according to the set length automatically and then displays seed

    6. Stop the operation:

    Press the stop button on the operation panel of the electric box or the emergency button beside the frame to stop the operation of the equipment.
