Description
Technical field
The utility model is related to produce the equipment of paper diaper.
Background technology
The production of paper diaper at present is entirely to be operated using automatic assembly line, is realized on automatic assembly line outer
The compound fixation of the components such as cover, absorptive core, three-dimensional shield, frontal waist plaster and Velcro.The structure of three-dimensional shield as shown in Figure 1,
It is made of the containment flaps 1a of rear barricade water repellent nonwovens 1 and both sides, containment flaps are by flank water repellent nonwovens 2 and elastic 3
It forms, 2 one side of flank water repellent nonwovens is fixed in rear barricade water repellent nonwovens 1, and another side is coated elastic 3 by glue
Firmly.1 position of barricade water repellent nonwovens is in the rear of paper diaper afterwards, is mainly used for preventing urine rearward leakage, containment flaps
Position is in the both sides of paper diaper width direction, and containment flaps are mainly used for preventing the lateral leakage of urine.Three-dimensional shield specifically into
Type process is as follows：1. barricade water repellent nonwovens are cut off after, and rear barricade water repellent nonwovens are fed by the first haulage gear, the first glue
Then rifle cuts off rear barricade water repellent nonwovens glue spraying by cutter；2. containment flaps are molded, first by flank water repellent nonwoven
Cloth will packet elastic side dig come, the elastic packet by hot melt adhesive is sprayed then is turned down in flank water repellent nonwovens 2, with another road
Hot melt adhesive carries out edge sealing, passes through cladding plate aftershaping；3. flank water repellent nonwovens 2 are sticked in rear barricade water repellent nonwovens 1.
After existing cut-out barricade water repellent nonwovens cutter as shown in Fig. 2, cutter include tool apron, cutter a and
Bottom knife roller b, cutter a are single-blade thickness blade, and cutter a thickness between 12-15mm, refuse by cutter a barricades after being cut with bottom knife roller b
For vertical cut state during water non-woven fabrics, i.e. cutter a is overlapped with bottom knife roller b diameter extended lines, during cutoff action after barricade water repellent nonwoven
The linear speed V3 ＜ cutter linear speed V1=bottom knife roller linear speed V2 ＜ composite material linear speed V4 of cloth go out bottom knife roller when power causes to cut greatly
It is unstable to there is rotation, has moment to pause and overshoot phenomenon, causes rear barricade water repellent nonwovens Cutting Length unstable.
Barricade water repellent nonwovens will carry out hot melt adhesive glue spraying processing before cutting afterwards, and the sizing temperature of hot melt adhesive is at 110 °
Between~160 DEG C, general melting temperature can glue very much at 60 ° after melting, and rear barricade water repellent nonwovens heat in cutting process
Glue can be transferred on the blade of cutter, and band glue can be more serious after repeatedly cutting for blade, needs to shut down cleaning cutter, influence
Production efficiency.When containment flaps are molded, the hot melt adhesive dosage for spraying elastic is larger, since hot melt adhesive is very viscous, is coated in elastic
Hot melt adhesive can ooze out flank water repellent nonwovens and be transferred on cladding plate on a small quantity in journey, and cladding plate band glue can be more next after long-play
It is more serious, it eventually leads to flank water repellent nonwovens and is wrapped by plate and cling and break, cause machine down, product rejection, influence to give birth to
Produce efficiency.
In conclusion the former of existing paper diaper three-dimensional shield there are the problem of it is as follows：Barricade water repellent nonwoven after 1.
Cloth Cutting Length is unstable；2. barricade water repellent nonwovens hot melt adhesive in cutting process can be transferred on the blade of cutter after；3.
Hot melt adhesive can ooze out flank water repellent nonwovens and be transferred on cladding plate during elastic cladding.

The tool apron 62 of part has good conductibility, cutter 63 is freezed simultaneously by the conduction of tool apron, cutter 63 is coated with height in cutting
When warming the rear barricade water repellent nonwovens 1 of melten gel, hot melt adhesive curing is not transferred on cutter；
(2) containment flaps 1a is molded while rear barricade water repellent nonwovens 1 are cut off, and flank water repellent nonwovens 2 pass through the
Two traction feed arrangements 13 are fed to 9 direction of coating unit, first by flank water repellent nonwovens 2 will the side of packet elastic 3 dig, the
Two glue rifles 12 to by 2 glue spraying of flank water repellent nonwovens；Elastic 3 passes through third while flank water repellent nonwovens 2 are fed
Draw feed arrangement 11 to 9 direction of coating unit feed, third glue rifle 10 to by 3 glue spraying of elastic；At coating unit 9,
The elastic 3 for spraying hot melt adhesive is wrapped in flank water repellent nonwovens 2, edge sealing is carried out with hot melt adhesive, the packet arranged by splayed
Cladding plate aftershaping, when containment flaps 1a is between two blocks of cladding plates, the second refrigeration machine 81 passes through the second coolant connecting tube 82
Coolant is sent into two coldplates 83, cooling processing is carried out to coldplate 83 and cladding plate 92, cladding plate 92 is controlled 0~10
Between DEG C, cured to the cold by the hot melt adhesive around the flank water repellent nonwovens 2 of cladding plate 92 and its interior elastic 3, elastic 3 exists
Hot melt adhesive will not ooze out flank water repellent nonwovens 2 and be transferred on cladding plate 92 during cladding, when ensureing containment flaps 1a moldings
Flank water repellent nonwovens 2 are not wrapped by plate 92 and cling and break；
