Large paper diaper lug part short-cutting longitudinal pitching method and system for realizing method

Abstract

The invention discloses a large paper diaper lug part short-cutting longitudinal pitching method. The method comprises the following steps: S10, carrying out continuous and sequential slitting on a large lug part material belt by adopting a lug part short-cutting device, thus forming a left lug part A and a right lug part B; and S20, adsorbing the cut left lug part A and right lug part B by a first adsorbing cutter anvil and a second adsorbing cutter anvil, respectively, and enabling the cut left lug part A and right lug part B to rotate along with the first adsorbing cutter anvil and the second adsorbing cutter anvil. The invention further provides a system for realizing the large paper diaper lug part short-cutting longitudinal pitching method. The system comprises the lug part short-cutting device, a transmission-side longitudinal pitching device, an operation-side longitudinal pitching device and a left-right side lug part pitching device, and the transmission-side longitudinal pitching device and the operation-side longitudinal pitching device are respectively arranged at the outer side of the lug part short-cutting device. The method and the system have the advantages that the structure is simple, the use is convenient, the stability is good, and the waste caused by raw material cutting can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of production of disposable sanitary products, in particular to a method and a system thereof for longitudinally changing the length of large ear pieces of diapers. Background technique [0002] At present, the degree of automation of the diaper production line is getting higher and higher. The existing diaper production equipment inevitably needs to cut the raw materials, and the discontinuous semi-finished products are transferred or transferred at variable speeds. There are often side materials, waste of materials, and the pitch-changing mechanism is huge, and the product size cannot be fully guaranteed. In order to make the manufacturing process simple and the product size guaranteed, there is an urgent need for a simple structure, easy to use, good stability, and can be used. The method and the system thereof can effectively avoid the waste caused by the cutting of raw materials. Contents of the inven...
