KDF2 filter rod forming machine was introduced into our country in the middle 1990s, by now some parts and electrical component have been worn and needed over hauling and replacing. As some early design defects, the customers are keen to modify and repair these machines. According to the market demands, we proudly present the a series of maintenance and renovations for KDF2.

The maintenance & renovation for KDF2

l PLC renovation in electrical control system realizes the communication between PLC and servo system by adopting SIMENS S7-300 series controller and PROFIBUS-DP bus.

l The blooming rollers, threaded rollers and glycerin pump of AF2 are drove independently by servo-motor. It is easy to set parameter according to process requirement, which ensures the quality of product and reduces rejects.

l Main motor adopts AC frequency conversion motor instead of DC motor, which overcomes the fluctuation of DC motor and is convenient for maintenance.

l By improving bobbin splicing mechanics and servo motor, it accomplishes the replacement of the bobbin at a high speed. The renovation avoids the inferior quality caused by the change of speed when the bobbin is replaced.

Renovation for glycerin nebulization system

l The glycerin nebulization mechanics is to send the glycerin into a distribution by a high pressure pump, then pre-heat the glycerin through 7 heaters, and then be nebulized by 7 nozzles. The granular glycerin is meticulous and even, being spread over the tow well.

The auto-balance instrument for filter tow

It can keep the surface of the extracted tow in a height automatically ( including in replacing new & old tow bag ), which effectively improve the suction resistance of filter rod. Meanwhile a precise electronic platform scale is installed on the auto-balance instrument.

Technical parameter

l Max lifting height:1550mm

l Precision for height controller: 1mm

l Max lifting load: 800kg

l Range of the electronic scale: 1000kg

l Precision of the electronic scale: ±0.2 kg

l Power: 0.1 kw

Renovation for diameter inspection system

The hardware design of diameter inspection system introduces high-resolution CCD as photosensitive device and high-speed SCM to control the output of inspection system. It can measure the object which diameter is less than 10mm. The precision is 0.1mm.

Modification for specification of filter rod

We can modify the length and diameter of filter rods as per the customers' requirements.
