Resin short bed

The invention relates to a resin short bed which comprises a transparent square cylinder, a first sieve plate, a second sieve plate, an end cover, a bottom box and a square transparent resin bin, thefirst sieve plate and the second sieve plate are sealed and fixed to openings in the upper end and the lower end of the transparent square cylinder respectively, the end cover is sealed and fixed to the upper side of the first sieve plate, and an opening in the upper end of the bottom box is sealed and fixed to the lower side of the second sieve plate; the outer sides of openings in the upper endand the lower end of the transparent square cylinder are each fixedly sleeved with a flange ring. The square transparent resin bin is arranged in the transparent square cylinder; according to the invention, equivalent equal volume is realized, so that the flowing time of the material in the resin column is ensured to ensure that the material is in full contact with resin; meanwhile, the depth of each honeycomb-shaped flow
