Automatic release paper roll unreeling and replacing mechanism of sanitary towel packaging machine

Abstract

The invention discloses an automatic release paper roll unreeling and replacing mechanism of a sanitary towel packaging machine. The mechanism consists of a release paper roll unreeling device and a release paper roll replacing device. In the release paper roll replacing device, a servomotor drives a synchronous belt pulley to drive a transmission shaft and a connecting plate to synchronously rotate, wherein the connecting plate is symmetrically provided with an upper release paper roll unreeling air expanding shaft and a lower release paper roll unreeling air expanding shaft. In the release paper roll unreeling device, a servomotor drives a driving synchronous belt pulley to drive a rotating bearing bush to synchronously rotate, wherein the rotating bearing bush synchronously drives an upper driven synchronous belt pulley or a lower driven synchronous belt pulley to be correspondingly linked with the upper release paper roll unreeling air expanding shaft or the lower release paper roll unreeling air expanding shaft. Compared with the prior art, the automatic release paper roll unreeling and replacing mechanism carries out the automatic material replacing and receiving of release paper under the control of a PLC (programmable logic controller), so as to improve the working efficiency and reduce the packaging cost.

Description

technical field [0001] The invention relates to a sanitary napkin packaging device, in particular to a release paper changing and splicing device integrating the functions of automatic roll unwinding and roll changing. Background technique [0002] At present, the replacement of the release paper in the sanitary napkin packaging equipment needs to be done manually, the packaging cost is high, and the work efficiency is low, especially it cannot adapt to other supporting devices that operate at high speed in the sanitary napkin packaging machine. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a release paper automatic releasing and roll changing mechanism of a sanitary napkin packaging machine. The release paper automatic release and roll change mechanism can realize the automatic material change and connection function of the release paper, which improves work efficiency and reduces packaging costs. [0004] To achie...
