Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking machinery and relates to a paper-leading water needle traction structure. Background Art

[0002] The operating structure of the paper water needle head of the household paper machine is mostly as follows: Figure 1 As shown in the figure, the water needle seat moves back and forth on the linear track through the forward and reverse rotation of the motor, thereby achieving the purpose of cutting the wet paper surface. The back and forth movement is completed by the main sprocket, the driven sprocket and the chain traction.

[0003] Current defects: 1. The engagement stability between the water needle seat 5 and the track 4 is not good, and derailment and jamming are frequent; 2. The transmission chain 3 is relatively long. In order to reduce the chain drop and ensure the smooth operation of the chain, the chain connection is generally protected by a pipe, which will cause the link and the pipe mouth to get stuck, affecting the stability of the reciprocating motion.
