Description
Technical field
The present invention relates to field of machining, more particularly to a kind of cloth set composite and method.
Background technique
With the raising of people 's material life and the level of cultural life, requirement of the people to clothes is higher and higher, in material
On from pervious homogenous material type gradually develop into composite material type, develop into few seam type from pervious sewing type in appearance.
In the cloth manufacturing process of down jackets, the prior art is reached by the storage suede technique for carrying out lattice needle seam to fabric
Villus will not due to movement heap suede purpose, however the big technique of this method suture amount it is cumbersome, sewing during also can be to fabric
Intensity cause certain damage, villus can be caused to go out suede from pin hole because of suture amount greatly.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, proposing a kind of cloth set composite and method, by phase
Opposite is compounded with hot melt film base fabric in advance and face cloth is compound according to specific lines, makes to form storage suede sky between base fabric and face cloth
Between, instead of the storage suede technique of lattice needle in the prior art seam.
The invention is realized by the following technical scheme:
A kind of cloth set composite, for making to be formed base fabric and face cloth between base fabric and face cloth according to specific lines is compound
Store up suede space, the opposite face of base fabric and face cloth is compounded with hot melt film in advance, including rack, is rotatably provided in rack and phase
Mutually parallel base fabric hot-rolling, face cloth hot-rolling, flower roll and pressure roller, pressure roller can move between position of readiness and operating position, to
Pressure roller and flower roll arranged for interval when seat in the plane is set, at operating position, pressure roller is bonded with flower roll, and base fabric and face cloth are corresponding by base fabric
Enter the lines that protrusion is formed between flower roll and pressure roller, in flower roll after hot-rolling and the heating of face cloth hot-rolling, flower roll and pressure roller cooperate
Pressure keeps base fabric and face cloth compound at lines.
It further, further include support roller and actuator, support roller is parallel with the flower roll positioned opposite, and support roller can turn
It is dynamic be arranged on the rack and can the relatively described flower roll move horizontally, actuator can drive support roller to hold out against in the flower roll backwards to institute
The side of pressure roller is stated, support roller, which is provided with heating structure, can transfer heat to the flower roll.
Further, the actuator is the first cylinder or the first oil cylinder.
It further, further include mounting device for installing the pressure roller, which includes being supported on the pressure
The driving mechanism that two regulating mechanisms and the driving pressure roller at roller both ends act between operating position and position of readiness, adjusts machine
Structure includes crane, sliding rack, bearing block, lifting regulating mechanism, front and back regulating mechanism, and crane liftable is movably arranged at
In rack, lifting regulating mechanism for drive crane lifting moving adjust, sliding rack can the relatively described flower roll be movably arranged
On crane, bearing block can the relatively described flower roll be arranged on sliding rack movably forward and backward, front and back regulating mechanism can drive institute
It states bearing block and is moved forward and backward adjustment, the driving mechanism drives the sliding rack of two regulating mechanisms synchronous in operating position and standby position
It is moved between setting.
Further, the driving mechanism include the synchronizing shaft being rotatably provided between the crane of two regulating mechanisms,
Two swing arms at synchronizing shaft both ends are set, be arranged on sliding rack with the drive hole of swing arm cooperation and driving synchronizing shaft rotation the
Two cylinders, the bearing in drive hole is provided in swing arm, and the second cylinder passes through actuating arm and synchronous axis connection.
It further, further include the third cylinder of the mobile help roll of liftable and driving help roll lifting moving, this is auxiliary
Help roller to be arranged in the lower section of the flower roll, be movable in the flower roll be bonded, it is compound after cloth by help roll with it is described
Between flower roll, the cloth between help roll and the pressure roller is made to keep being bonded with the flower roll.
Further, the decalcomania is corrugated or dentation.
A kind of cloth complex method, for making to be formed base fabric and face cloth between base fabric and face cloth according to specific lines is compound
Suede space is stored up, is included the following steps:
Preparation: pressure roller, support roller, help roll are bonded flower roll and enter working condition, and base fabric hot-rolling, face cloth hot-rolling add
Heat to assigned temperature, flower roll is heated to assigned temperature by support roller；
Upper roller preheating: base fabric and face cloth enter in device, and base fabric upper roller is preheated in base fabric hot-rolling, and face cloth upper roller is in face
Cloth hot-rolling is preheated；
Hot-pressed printing: in flower roll, flower roll makes base fabric and face cloth at lines with pressure roller cooperation pressure for bottom and face cloth upper roller
It is compound；
Stablize compound: the cloth after compound passes through between help roll and flower roll, makes the cloth between help roll and the pressure roller
Material keeps being bonded with flower roll up to roller out；
Finished product goes out roller: cloth completion is compound, goes out roller from help roll.
The invention has the following beneficial effects:
1, compound according to specific lines by being compounded with hot melt film base fabric and face cloth in advance to cloth opposite face, make base fabric
Storage suede space is formed between the cloth of face, instead of the storage suede technique that lattice needle in the prior art stitches, can not destroy web surface
On the basis of carry out storage suede, technique is easier, and combined efficiency is high, and composite quality is good, is not easy to run suede.
2, flower roll is heated by support roller, prevents heating system from directly heating the situation for causing temperature excessively high to flower roll.
3, support roller pressure roller cooperates, and balances pressure suffered by flower roll horizontal direction, prevents flower roll from deforming because of external force.
4, the decalcomania of corrugated or dentation can prevent filling suede material from moving in cloth.
