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 technology
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 cut-out, then new material stickup get on, continue to reach the standard grade and not shut down.This joint style has the following disadvantages：
1. it is askew to be easy patch when taping, patch wrinkle causes material sideslip or crumples.
2. it is not easy to operate in non-stop-machine while while leading the new material for posting adhesive tape into splicer, it may be useless in material
The material unreeled has been sticked in the case of complete causes product rejection.
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 adhesive tape patch is bad, there is exposed adhesive tape that can be adhered on straining pulley or traction wheel and cause to stop
Machine wastes material and wastes time.
In addition, there is some to be used for the cutting heat seal splicing body of disposable sanitary articles material, have a disadvantage in that with slotting
Since slotting cutting edge is zigzag when cutting edge cuts off material, and long material especially soft to some fibers, which can't cut, to be caused to spell
It connects and unsuccessfully shuts down；And it is complicated, it generally requires to use multiple cylinder cooperatings, it is inconvenient.
Invention content
The purpose of the utility model is to overcome the prior arts there are when the cutting heat seal splicing of disposable sanitary articles material, adopts
And long material especially soft to some fibers with slotting cutting edge, which can't cut, causes splicing unsuccessfully to be shut down；And it is complicated, often
It needs to use multiple cylinder cooperatings, unhandy defect provides one kind and carries out material by the heating element that fuses
Fusing is very suitable for disconnecting the especially soft and long material of fiber instead of the slotting cutting edge in cutting heat seal splicing body；Energy
Fusing splicing is not shut down, immediate stability is spliced, it is easy to operate, improve working efficiency and Improving The Quality of Products；Mechanism is simplified,
It is stretched in opposite directions using only a pair of of cylinder, the switching mechanism of easy to operate raw material.
Technical solution adopted by the utility model to solve its technical problems is：A kind of switching mechanism of raw material, packet
Including rack is fixed with intermediate backplate in rack, and two cylinder fixed seats are relatively arranged on the both sides of intermediate backplate, and each cylinder is fixed
It is equipped with transfer passage between seat and intermediate backplate, splicing cylinder is mounted in each cylinder fixed seat, two splice cylinder
External part is oppositely arranged；It is respectively and fixedly provided with fixed block on the external part of each splicing cylinder；Along transfer passage, on each fixed block
It is sequentially installed with elastic telescopic component, fusing heating element and splicing heating element；Elastic telescopic component includes flexible
Bar, spring and holding pad are provided with blind hole on fixed block, and the oral area of blind hole coaxially fixes restraining position ring block, and the internal diameter of spacing ring is less than
The internal diameter of blind hole；Telescopic rod is arranged in spacing ring, and telescopic rod is located at the end in blind hole and is fixed with flange, and the diameter of flange is big
In the internal diameter of spacing ring, spring pocket is set on telescopic rod, and is located between spacing ring and holding pad；In the piston of splicing cylinder
When bar is in longest stretching state, the fever head of each holding pad and each fusing heating element fits in intermediate backplate
On, and the fever head of two splicing heating elements is bonded to each other.
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 both sides of the heat seal splicing body of the utility model are fixedly installed uncoiling material B and wait for
Uncoiling material C, uncoiling material B is finished in machine running process, waits for uncoiling material C in non-stop-machine change, at this moment
Need to use the heat seal splicing body of the utility model.When uncoiling material B is conveyed, it need to will just wait for that uncoiling material C is ready to
In heat seal splicing body.The piston rod of the splicing cylinder on right side is retracted first, flows out enough operating spaces, then will wait for uncoiling
Material C is led into heat seal splicing body, and it is more than the heating head for splicing heating element to wait for that uncoiling material C is had to.
2. the second action phase：The piston rod of the splicing cylinder on right side is extended into initial position at this time.
3. third action phase：Automatically control or manual control on the right side of splicing cylinder piston rod push right side binder
Plate will wait for uncoiling material C to be pressed on intermediate backplate and wait for uncoiling.
4. third action phase：After running a period of time, change of lap is needed when detection device detects that uncoiling material B is used up soon
When, uncoiling material B stop motions (operation material requested discharges storage material by follow-up tension mechanism), left side holding pad is in left side
Splicing cylinder promotion under uncoiling material B is pushed down, at the same time left and right two splicing cylinders work at the same time, two splicing fever
Component pushes down two materials, and materials at two layers itself is fused to together by transient heating；And two fusing heating elements are equal
Material is pressed in the both sides plate face of splicing body intermediate bulkhead 11, fusing heating element heating on the left of automatic or manual control
Uncoiling material B is fused, so latter two splicing cylinder resets, and to complete two material splicings, changes C-material work into.
5. the 5th action phase：Then the uncoiling material B being finished is changed into and waits for uncoiling material D, and be repeated in above
One, the first operation of two, three action phases (wherein, the left and right sequence of movement of each cylinder is exchanged).
The utility model drives splicing heating element movement by splicing cylinder, until two splicing hairs being oppositely arranged
Hot component clamps B, C-material, is generated heat by controller or the fusing heating element of manual control B material side, fusing hair
B material is pressed on intermediate backplate and fuses by hot component, and incision position is carefully and neatly done；At the same time, splicing heating element pushes down C
Material is contacted with another splicing heating element, so that materials at two layers itself is fused to together, joint tensile strength is big；This reality
With novel askew, the patch wrinkle phenomenon that avoids the artificial patch brought of taping together of being fused to by materials at two layers itself；It can be in former material
In the case that material is finished, successfully two materials is welded to not shutting down and is avoided together manually in the feelings for not shutting down rubberizing
The possibility of product rejection is generated under condition；It can be avoided simultaneously because of adhesive tape much smootherly by straining pulley, traction wheel and packing mechanism
The bad or splicing of patch unsuccessfully causes machine down to waste time, and the mechanism is easy to operate, quick reliable, economical and efficient.In addition,
The heating element that fuses is located between the heating head and holding pad of splicing heating element, convenient for molten between two fixing points
It is disconnected；The utility model fuses to B material by the heating element that fuses, instead of slotting cutting in cutting heat seal splicing body
