The invention discloses a kind of preparation method of acupuncture cotton, its drip irrigation device be successively include following preparation technology, shredding tentatively combing formed fibre thin layer lapping pinprick reinforcement have a shave flash removed apply sizing material cooling stamp cut-out packaging.The sizing material coated on the surface of acupuncture cotton causes the surface of acupuncture cotton to assign layer protective layer, it is to avoid the problem of the tear that occurs under prolonged use.
Description
Technical field
The present invention relates to acupuncture cotton field, more particularly to a kind of preparation method of acupuncture cotton.
Background technology
Acupuncture cotton be it is a kind of without weaving, directly by fiber acupuncture into flocculus product, with natural cotton, cashmere,
The acupuncture cotton of the making such as wool, camel hair, flaxen fiber, bamboo fibre, zein fiber, soybean fiber does filler or base material, production
Product are soft, fluffy, breathe freely, and the life with us compares to press close to, and can be not only used for the filling of clothes, dress ornament, cushion, household articles
Material, it can also be used to the decoration of indoor wall, it is also possible to make the material of shoe-pad.
The preparation method of conventional acupuncture cotton is：
(1) fiber is uniformly mixed, feeding opener carries out shredding；
(2) through carding machine cards；
(3) lapping is carried out by lapping machine；
(4) through needing machine, lower thorn and upper thorn；
(5) toasted through baking oven；
(6) shaped through pressure roller cooling, final output finished product acupuncture cotton.
But the acupuncture cotton of general common material is trampled and occurs that acupuncture cotton skin is broken for a long time in the bed course as sole
The phenomenon of damage, structure is slightly not excellent enough, and using effect is poor.
The content of the invention
Should in view of the deficienciess of the prior art, being utilized it is an object of the invention to provide a kind of preparation method of acupuncture cotton
The raw material of acupuncture cotton production has excellent structure strong.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of preparation method of acupuncture cotton, including following preparation technology,
Step 1：Cotton fiber is added into the shredding into thick opener, the fiber of block curling compacting is obtained preliminary shredding, passes through
The cotton fiber of preliminary shredding is tentatively combed through carding machine；
Step 2：Cotton fiber through tentatively combing is defeated fixed to cotton storage tank through air delivery pipe, and photoelectric control is made in cotton amount, cotton storage tank
Cotton fiber is combed by carding machine；
Step 3：Cotton fiber after combing is entered to after vibration-type cotton feeder through feed roll motor through refined opener shredding and after combing
And doffer；Step 4：Cotton-supplying roller is entered to by the cotton fiber of doffer, the effect through double cylinders, two pass husband is combed into Double-level Reticulated
Shape fibre thin layer；
Step 5：Gripping of the reticular fibre thin layer through clamping carbon curtain is conveyed, makes cotton fiber in the presence of not by external force, passes through
Reciprocating lapping is up to 7~18 layers；
Step 6：Fibrous layer in step 5 is fed into needing machine, reinforced through pre-needling, after main pinprick reinforcement, pinprick reinforcement of having a shave
Cloth is stored up through preliminary tension bracket；
Step 7：Cellucotton in step 6 is had a shave except deburring through heat conduction roller；
Step 8：Heated after the cellucotton in step 7 is coated into sizing material through gluing machine through heat conduction roller；
Step 9：The cellucotton heated through heat conduction roller is through air-cooled cooling；
Step 10：Cellucotton after cooling is through printing machine printed patterns, and the cellucotton after printing is through air-cooled cooling；
Step 11：Cellucotton after air-cooled cooling is cut to full-length through shut-off mechanism.
By above-mentioned technical proposal, the process in step 1 Jing Guo thick shredding can cause the cotton fiber of block curling compacting to obtain
To preliminary shredding, then cotton fiber is just at the fluffy state of comparison, then can be removed by preliminary combing in cotton fiber
The impurity such as iron nail；Cotton storage tank will be delivered to by the cotton fiber tentatively combed in step 2, be then combed again through carding machine again
Enable to cotton fiber scattered more uniform, and relatively fine impurity can be removed；Refined opener shredding in step 3
Process enables to scattered more uniform of fiber, and then cotton fiber is stretched by feed roll motor and doffer；In step 4
Two layers of reticular fibre thin layer can be formed by double cylinder and double doffer after cotton-supplying roller, so can be by scattered fiber
It is preliminary crosslinked together in screen cloth；The lapping of reciprocating in step 5, the stratum reticulare being paved into during lapping is defeated outward
Send, then will form edge staggeredly；Being reinforced in step 5 through pre-needling causes the fiber of lower floor and the fiber on upper strata to be crosslinked,
The thickness of lapping simultaneously reduces, and the cotton fiber on upper strata and the cotton fibre of lower floor then can be further caused by main pinprick reinforcement
Dimension crosslinking, is then enabling to upper strata and the surface of lower floor to be substantially at smooth state by pinprick reinforcement of having a shave；Step 7
Middle process heat conduction rolling is had a shave and the burr on acupuncture cotton surface can plate, and surface is more smooth；Cellucotton coating adhesive in step 8
Material enables to the structural strength of cellucotton to increase, and is difficult to be torn in the state of under tension, then adds by heat conduction roller
It is rapid that heat enables to sizing material to dry；Air-cooled energy in step 9 enable the acupuncture cotton after high temperature drying quickly to cool down；Step
It can assign acupuncture cotton different colors acupuncture cotton printing in rapid 10, then the shut-off mechanism in step 11 can be transported conveniently
It is defeated.
The present invention is further arranged to：Thick opener is made up of 10 pieces of steel nail-plates in step 2, and rotating speed is 1200~1250
Rev/min.
The shredding of cellucotton can be facilitated in the scope by rotating speed control by above-mentioned technical proposal, in thick opener.
The present invention is further arranged to：Refined opener is made up of 10 pieces of steel nail-plates in step 3, and rotating speed is 1400~1420
Rev/min.
By above-mentioned technical proposal, the rotating speed control of refined opener can cause cellucotton to run through within the range, by
In the process by step 1 and step 2, the cellucotton reached in step 3 has been more loose, so the rotation of smart shredding
Speed within the range, starts excellent effect.
The present invention is further arranged to：Selection pre-needling machine is reinforced in pre-needling in step 6, and pre-needling machine is pin on single needle plate
Thorn machine, Needle Board density is 4500 pieces/meter, and pinhole diameter is 4.2mm；
Main pinprick reinforcement selects crosspointer plate dystopy Double felting needle felting machine, and Needle Board density is 13000 pieces/meter, and pinhole diameter is
1.83mm；Pinprick reinforcement of having a shave selects needing machine tow sides acupuncture of having a shave, and Needle Board density is 14000 pieces/meter, and pin hole is straight
Footpath is 1.83mm.
By above-mentioned technical proposal, the thickness ratio by the process cellucotton with acupuncture is larger, so Needle Board density
Small, pinhole diameter is big, facilitates acupuncture course；Selected in main acupuncture course needle plate density increase pinhole diameter reduce, be because
To reduce by with the thickness of the cellucotton after acupuncture, aspect acupuncture is passed through；Acupuncture of finally having a shave is mainly by cellucotton surface
Burr knit flat, surfacing.
The present invention is further arranged to：The heating-up temperature of heat conduction roller is 130~170 DEG C in step 7.
By above-mentioned technical proposal, the temperature of heat conduction roller within the range, is dried quickly, and enable to sizing material to stick
On the surface of cellucotton, stick firmly.
The present invention is further arranged to：Sizing material in step 8 includes the component of following parts by weight, 80~100 parts of poly- second
