The invention discloses production equipment of building materials, and particularly relates to an assembly line for producing plastic wall separating strip plates. The assembly line is a mechanics-electronics-hydraulics integrated full automatic assembly line and sequentially comprises a raw material transporting station, a mixing and stirring station, a forming station and a drying and hardening station; the assembly line is characterized in that the minimum takt time of the assembly line is 20-26 seconds, the time for producing a finished product of one plastic wall separating strip plate is 2 T, namely 40-52 seconds, the maximum time is for producing the finished product is 4-8 hours in a drying and maintaining process, each process is completed by a corresponding device, and the consumed times are respectively an integral multiple of the minimum takt time; the specific technology route comprises the steps of dry powder material automatic transporting, dry powder material distributing by measuring, dry mixing, wet mixing and stirring by adding a binder, forming, drying and hardening, and finished product storage. According to the technical scheme of the assembly line for producing the plastic wall separating strip plates, disclosed by the invention, the dry mixing and the wet mixing are divided, rhythm assembly line production is designed, energy-saving, environment-friendly, clean and continuous production of the plastic wall separating strip plates is realized, and meanwhile, the production quality stability of the plastic wall separating strip plates is ensured.
