This coating production line is specially designed for self-adhesive tape production equipment, which can be coated with solvent and water-based adhesive, PE and substrate technology

         You can also produce other tapes, those that need release coating, or those that only need glue coating

         Fortunately, the crawler with bearing film (drying and cooling part) can produce protective film tape at most temperatures

        We can make the following brief description

       ·Unwinding

       ·The film is pretreated, heated by a heating device and cooled by a cooling roller

       ·Release coating cam coating

      ·Direct coating, solvent or water-based, and the solvent or water evaporates

      ·Cooling of coating film, water cooling or air cooling

     ·Central control to minimize the gap between equipment

    The equipment structure can start from the standard structure, and then be integrated or transformed. Other institutions or equipment can be added to increase or expand the protective film process

  This technology has only been used in recent years, and pneumatic and electrical components have been upgraded to ensure stable product quality and reduce maintenance and accessories

                      The minimum length of the roll is 1000m and the maximum is 2000m, with longitudinal trimming (trimming the uncoated part), or cut into 5 layers with longitudinal trimming

· Maximum mechanical speed              200 m/min

·Maximum production speed            150 m/min following product chemical

                                                                                       According to the physical and chemical characteristics of the product

· Minimum production speed            10 m/min (for film tension goodmanagement) 

· Motor main motor                           CA，Frequency conversion control

· Man machine dialogue                       English

· colour                                                undetermined

· Installation environment                

                                                             Industrial environment, explosion-proof is not required

                                   Minimum + 5 ° C, maximum 42 ° C, maximum humidity 90%

           ·  Ambient temperature for heating reference      30°C

        · Device color

- Mechanical part                                      white 9010

- Control panel                                          ash 7035

- safeguard                                               yellow 1012

· Steel parts                                                   Protect with zinc or nickel plating

· Test element                                                I.S. International System 

· noise                                                               Less than 85 dB, with external exhaust fan and oven exhaust pipe. According to Guzzetti standard, the correction part is protected by sound isolation box

                                                         Because the operator needs to work here, the noise needs to be measured. The test point is usually one meter away from the equipment and 1.5 meters away from the ground
