Abstract

The invention discloses a laboratory paper sheet making machine, and belongs to the field of paper making experimental equipment. The laboratory paper sheet making machine comprises a transmission device, a swing arm, an air cylinder and a pulp storage tank, the bottom of the pulp storage tank is connected with a buffer tank in a sealed mode, and a manual opening device is arranged. A lower filter device is arranged at the position, closely attached to the bottom of the pulp storage tank, in the buffer tank, the bottom of the buffer tank is connected with a white water tank through a pipeline with a bottom regulating valve, and an upper filter device capable of moving along the inner wall of the pulp storage tank is arranged in the pulp storage tank. A plurality of air blowing holes are evenly formed in the bottom of the pulp storage tank, and are connected with an air blowing pipe. The transmission device is connected with the swing arm, the air cylinder is fixed to the swing arm, and a piston rod of the air cylinder is connected with the upper filter device. According to the laboratory paper sheet making machine, single-face dehydration and double-face dehydration of the laboratory paper sheet making machine can be achieved, the distribution condition of fine fibers and fillers in the paper thickness direction of top mesh forming and clamping mesh forming is simulated well, the structure is simple, manufacturing cost is low, use is convenient, and the laboratory paper sheet making machine has good use prospects.

Description

technical field [0001] The invention belongs to an experimental device in the field of pulping and papermaking, and in particular relates to a laboratory sheet copying device. Background technique [0002] The paper sheet copying machine is also called the paper sheet copying machine. It is an experimental instrument used to prepare hand-made paper sheets for paper performance tests, identification of pulp raw material properties and beating process specifications. It is a must for paper-making related scientific research units. One of the experimental equipment prepared. The duty of the paper copying machine is to make hand-written paper sheets that are closer to industrial paper. According to the requirements of the industrialized paper production process, the papermaking process mainly consists of the mixing of pulp and chemicals, sheet forming, pressing and drying. [0003] The sheet forming process is a key component of the sheet copying machine. Paper forming mainly...
