Description
Technical field
The utility model belongs to amenities production equipment field, and in particular to a kind of switching mechanism of raw material.
Background technique
The splicing process of disposable sanitary articles material is usually to cut off the material for unreeling completion, then bond it to new
It unreels on material, double faced adhesive tape is typically sticked to head end and the alignment of new uncoiling material, removes release paper above, then
Material is led to splicer, keeps adhesive tape position corresponding with stitching position, when detection device detects that material runs low by material
Material cutting, then new material is pasted, and continuation is online not to shut down.This joint style has the disadvantage in that
1. it is askew to be easy patch when taping, patch wrinkle causes material sideslip or crumples.
2. it is not easy to operate when new material that is non-stop-machine while will posting adhesive tape is led into splicer, it may be useless in material
The material unreeled has been sticked in the case where complete causes scrap of the product.
3. disposable sanitary articles material is softer and adhesive tape is relatively hard, the non-woven fabrics at adhesive tape is posted in packing
Being not easy packing or adhesive tape can hinder material to cause to shut down by packing plate.
4. if having exposed adhesive tape that can be adhered on straining pulley or traction wheel adhesive tape patch is bad and causing to stop
Machine wastes material and wastes time.
Summary of the invention
The purpose of the utility model is to overcome the prior arts there are when spliced materials, by the way of taping, is easy patch
Askew, patch wrinkle defect, providing a kind of heating element heats is fused to materials at two layers itself together；Without rubberizing, people is avoided
Work tape bring patch it is askew, patch wrinkle the phenomenon that；Avoid manually in the case where not shutting down rubberizing generate scrap of the product can
The switching mechanism of the raw material of energy property.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of switching mechanism of raw material, packet
Base is included, knife fixing plate is fixed on base, cutting edge channel is provided through on knife fixing plate, the two sides of knife fixing plate are equipped with cylinder branch
, press cylinder and splicing cylinder are mounted on each cylinder saddle, press cylinder and the piston rod for splicing cylinder stretch square
To being arranged in parallel, the extension end of press cylinder and splicing cylinder is located at the two sides in cutting edge channel；Each press cylinder is used
Disposable sanitary articles material is pressed on knife fixing plate in by stretching out piston rod；It is fixed on the extension end of each splicing cylinder
There is fixed plate；One end of fixed plate is equipped with blade, and the other end is equipped with several heating elements；The cutting edge of blade moves rail
Mark extends in cutting edge channel；After the heating head of the heating element of knife fixing plate two sides is used to stretch out with the piston rod of splicing cylinder,
Two layers of disposable sanitary articles material is pressed against and is welded to one.
A kind of course of work of the switching mechanism of raw material of the utility model is as follows:
1. the first action phase: the heat seal splicing body two sides of the utility model are fixedly installed uncoiling material and to uncoiling
Material, a roll of material (uncoiling material) is finished in machine running process, changed in non-stop-machine situation an other roll of material (to
Uncoiling material), it at this moment just needs to use heat seal splicing body.It, just need to be by the C-material to uncoiling when the conveying of the B material of uncoiling
It is ready in heat seal splicing body.The piston rod of press cylinder and splicing cylinder is retracted first, it is empty to reserve enough operations
Between, then C-material led into heat seal splicing body, C-material connector has to the heating head more than heating element.
2. the second action phase: C-material is in state to be spliced at this time, and the press cylinder Work Promote extension end on right side will
C-material is pressed on knife fixing plate.
3. third action phase: after operation a period of time, when external detection device detects that B material needs change of lap, B
Material stop motion (operation material requested discharges storage material by subsequent tension mechanism), the press cylinder in left side push extension end
B material is pressed on knife fixing plate, at the same time left side splicing cylinder promotion under heating element heating head also by B material
It is pressed in the heating head of the heating element of relative position.The both ends of B material are fixed at this time, and blade can lead to B material in cutting edge
It is easily cut off at road.Meanwhile B material and C-material are pressed between the heating head of two heating elements, pass through heating element
Heating head heating, be clipped in the B between the heating head of two heating elements, C-material and itself be fused to together, then press cylinder and
Splice cylinder to reset, to complete two material splicings, changes C-material into and conveyed.
4. the 4th action phase: and then change the B material being finished into D material and wait for uncoiling, and be repeated in above first and second
The operation of action phase, wherein the left and right sequence of movement of each cylinder is exchanged.
The splicing cylinder of the utility model drives the heating head of heating element mobile, until two heating units being oppositely arranged
Heating head clamping B, the C-material of part, heating element heats are fused to materials at two layers itself together, and joint tensile strength is big；
