The work aims to design a stamping pulp feeding machine with respect to great labor intensity, low efficiency and high labor costs by artificial operation of current stamping pulp feeding. By using the conflict resolution principle of TRIZ, the stamping pulp automatic feeding machine was designed. Problems in the design process were summarized and analyzed. According to the conflict matrix of automatic feeding machine, the corresponding innovative design principle was obtained and the best principle was chosen to solve the problem of the technical conflict in the design through analysis and comparison. And mechanical analysis was conducted by using finite element software for sliding sleeve. Automatic feeding machine designed based on TRIZ theory may realize automatic material searching, automatic clamping, automatic lifting, automatic rotation and automatic feeding. This feeding machine has completely replaced manual operation, with an increase of 38% in the production efficiency.
