The invention discloses a paper pulp raw material treatment device. The paper pulp raw material treatment device comprises a papermaking machine, a power cavity is formed in the papermaking machine, and motor sliding grooves are formed in the front end wall and the rear end wall of the power cavity. According to the paper pulp raw material treatment device, a set of operation of feeding, crushing,stirring, mixing, heating, forming and discharging can be completed, the problem of low efficiency of traditional manual paper making is solved, the ecological production efficiency is improved, meanwhile, the paper pulp raw material treatment device can be small in size and can be used in an office, thus waste paper in the office can be directly produced into new paper, and energy sources are saved; according to the paper pulp raw material treatment device, through transmission cooperation of machines, the working efficiency of the paper pulp raw material treatment device is improved, the possibility of errors is decreased, meanwhile, a single motor is adopted to realize multiple functions, the cost of the paper pulp raw material treatment device is lowered, and energy consumption is saved; and the paper pulp raw material treatment device can reprocess the waste paper into paper pulp to be used for paper making.
