Problems solved by technology
[0002] After the pulp is uniformly treated in the papermaking process, due to the large amount of water in the pulp, it is necessary to squeeze out the water during the forming process of the paper product. The vacuum roller support is a commonly used dewatering part on the paper machine. In the process of processing and production, it is necessary to use a drilling machine to drill holes. Now some drilling machines have unreasonable drill structure settings, poor drilling results, and low drilling accuracy.

Description
technical field [0001] The invention relates to the technical field of papermaking technology, in particular to a spindle box structure. Background technique [0002] After the pulp is uniformly treated in the papermaking process, due to the large amount of water in the pulp, it is necessary to squeeze out the water during the forming process of the paper product. The vacuum roller support is a commonly used dewatering part on the paper machine. In the process of processing and production, it is necessary to use a drilling machine to drill the water-absorbing hole. Now some drilling machines have unreasonable drill structure settings, poor drilling effect, and low drilling accuracy. Contents of the invention [0003] In order to solve the above problems, the present invention provides a spindle box structure, which is compact in structure and reasonable in design, ensuring the drilling accuracy of the drill bit. [0004] Its technical solution is as follows: a spindle box...
