Invention content
First purpose of the present invention is in view of the above-mentioned problems existing in the prior art, to provide a kind of environmentally friendly and final product quality
High spun lacing method net-forming process.
Second object of the present invention is to provide cutting device used in above-mentioned net-forming process.
First purpose of the present invention can be realized by following technical proposal：
A kind of spun lacing method net-forming process, the technique include the following steps：
A, it stocks up：The corium fabric net and non-woven fabrics of the standby common material of choosing；
B, high-pressure water-jet：Above-mentioned corium fabric net is fitted on non-woven fabrics to and is made the two retaining surface contact, is then utilized
Common spun-laced machine carries out high-pressure injection to corium fabric net, and corium fabric mesh portions are embedded in non-woven fabrics under high pressure water flow effect
It is interior, so that corium fabric net is stablized mutual obvolvent with non-woven fabrics, obtains blank；
C, drying：Above-mentioned blank is dried；
D, it winds：By the blank coiling after drying on material storage tube；
E：Cutting：Material storage tube with blank is moved to by winder station at cutting station, then in cutting station
The blank cutting of winding is the finished product spunlace non-woven cloth of setting length by place.
Corium fabric net is molded for head layer ox-hide particle by common fiber net-forming process.
This spun lacing method net-forming process creativeness interconnects corium fabric net with what non-woven fabrics was stablized, then according to
It is secondary through drying, winding and cutting, finally obtain the spunlace non-woven cloth of setting length.
In above-mentioned spun lacing method net-forming process, the pre- spun lacing pressure in the step B is 30-60/105Pa。
In above-mentioned spun lacing method net-forming process, blank is subjected to three-stage drying in the step C：Drying process one,
Two and drying process three are dried, blank is located successively through above-mentioned drying process one, drying process two and drying process three
Reason.
In above-mentioned spun lacing method net-forming process, the three-stage drying in the step C carries out in baking oven, in rack
For upper tool there are three baking oven, three baking ovens are a pair of with above-mentioned drying process one, drying process two and three process of drying process one respectively
It answers.

Degree is 60 DEG C-75 DEG C, and the drying time of the drying process two is 25-35 minutes, and drying temperature is 50 DEG C-65 DEG C, described
The drying time for being dried three is 40-60 minutes, and drying temperature is 35 DEG C-40 DEG C.
Second object of the present invention is realized by following technical proposal：
A kind of cutting device, including rack are axially fixed with shaft in the rack, storing are circumferentially fixed in shaft
Cylinder, which is characterized in that the present apparatus includes actuator, position limiting structure and cutter, and above-mentioned material storage tube is cylindrical on the outside of material storage tube
With several groovings being axially concaved along it, above-mentioned cutter includes tool apron in a ring and several blades being connected on tool apron,
Above-mentioned tool apron is connected in rack and tool apron and material storage tube end face, and insert is circumferentially connected on tool apron and blade section
It stretches out on the inside of tool apron, above-mentioned position limiting structure can be such that material storage tube stops between rack and material storage tube and after position limiting structure action
To setting position, insert is corresponded with grooving after position limiting structure limits material storage tube.
While shaft rotates, the axial material storage tube being connected on it with rotating together.The material storage tube of rotation will be thus will
Spunlace non-woven cloth bloom stable it is wound thereon.
After spunlace non-woven cloth bloom stable is wound on material storage tube, actuator pushes material storage tube to be moved to cutter.At this
Position limiting structure, which limits material storage tube, in the process ensures that several blades of cutter can be embedded in correspondence correspondingly in setting position
Grooving at, so that the spunlace non-woven cloth bloom stable on material storage tube be blocked.
Certainly, after material storage tube translation, spunlace non-woven cloth blank subsequently to be cut still can be adhered on material storage tube, above-mentioned
Only cutting is located at the part spunlace non-woven cloth on material storage tube for cutting.
Actuator is oil cylinder, and material storage tube can be pushed after the piston rod translation of oil cylinder.
In order to ensure to stablize cutting, also there is a Feed servo system part, Feed servo system part to be fixedly connected with tool apron in rack, leads to
Feed servo system part energy band moving knife seat is crossed to translate relative to material storage tube.
Meanwhile in order to avoid tool apron and position limiting structure card resistance, tool apron downside has perforative notch, leads to when tool apron translates
It crosses above-mentioned notch and can stablize and cross position limiting structure.
In above-mentioned cutting device, the material storage tube is cylindrical in shape and has recessed round-bead seat, the circle on the inside of it
There is ball in pearl seat and ball part is stretched out on the inside of material storage tube and is resisted against in shaft.
In above-mentioned cutting device, above-mentioned circumferential direction is distributed on round-bead seat and corresponding ball-point pen type on the inside of material storage tube
At an osculating element, two and two osculating elements of the quantity of the osculating element are located at material storage tube both ends.
It can guarantee that material storage tube is in rolling contact with shaft under the action of two osculating elements, position limiting structure can in this way will store up
It will not be by rigid shock power after barrel locking.
