Is there any high speed train from linyi to weifang city? How to go?

I'm afraid train service is unavailable for the route, let alone high speed ones. You are suggested to travel by bus. At Linyi General Bus Station, direct buses are scheduled from 06:00 to 18:00 every half an hour. This is an easy way to go. The travel time is 3.5-4h and it costs CNY73 per person.
