Description
Technical field
The present invention relates to a kind of device of producing deadening felt, especially relate to a kind of supper-fast shaped device and application thereof of deadening felt.
Background technology
At present, deadening felt production technology is such: on production line, flat the semi-finished product of deadening felt felt is produced, then be transported to formation mould workshop and carry out moulding and die-cut, this technique is roughly such: the first step, felt is produced, felt is produced and is completed on felt production line, after felt production line need to mix various fibers, through baking oven, heating makes in fleece chemical fibre partly melt after combing, air lay, bonding is cotton fine by being cooled to felt, namely produces the semi-finished product of special-shaped deadening felt; Second step, molding press cutting, the flat felt of semi-finished product moves to finished product workshop, and baking oven post bake 140 seconds, melts chemical fibre completely, and felt blanket is put into mold cools down moulding approximately 160 seconds.The shortcoming of doing is like this: 1) the single part production cycle long, baking oven post bake time and moulding are about 300 seconds cool time, i.e. approximately 300 seconds single part production cycles; 2) baking oven post bake, energy consumption is high; 3) semi-finished product felt moves on to workshop, and station is many, and operation is many.Above 3 are just enough to make this explained hereafter not preponderated in the modern society of costization market economy with keen competition.High and the high production method of various kinds cost for energy consumption like this, the present invention proposes a kind of supper-fast shaped device and application thereof of deadening felt.
Summary of the invention
Object of the present invention is exactly to provide in order to overcome the defect that above-mentioned prior art exists that a kind of production efficiency is high, production cost is low, supper-fast shaped device and the application thereof of the deadening felt of low energy consumption.
Object of the present invention can be achieved through the following technical solutions:
A kind of supper-fast shaped device of deadening felt, this device comprises the felt materials distribution mesh mould, baking oven heating mesh mould, fast cooling shaping mesh mould and the die cutting die that connect successively by conveyer belt, the porch of described felt materials distribution mesh mould is provided with the traction roller of a pair of positive and negative rotation, in the die cavity of described felt materials distribution mesh mould, be provided with successively from front to back 10 independently spaces, each space is provided with an independently air door.
Described baking oven heating mesh mould comprises mold and bed die, and described bed die is provided with blowing mouth.Baking oven heating mesh mould has two effects, and the one, chemical fibre is melted cottonseed cake heating, the 2nd, by cottonseed cake preformed, obtain felt blanket.
Described fast cooling shaping mesh mould comprises mesh patrix and mesh counterdie, in described mesh patrix and the profile of mesh counterdie, is laid with aperture, and described mesh patrix is provided with suction opeing, and described mesh counterdie is provided with air inlet.
An application for the supper-fast shaped device of deadening felt, this application comprises the following steps:
(1) fibrous material mixing, under the centrifugal force of traction roller and the suction acting in conjunction of felt materials distribution mesh mould, enters in felt materials distribution mesh mould;
(2) when in felt materials distribution mesh mould in the time that air door corresponding to first space is opened, fibrous material is just blown in first space, how many fibrous materials that the time that air door is opened is needed by each spatial volume decides, in felt materials distribution mesh mould, 10 air doors corresponding to space open and close one by one like this, fibrous material is evenly distributed in 10 spaces, obtains well-distributed cottonseed cake;
(3) cottonseed cake, by heating and preformed in conveyer belt input baking oven heating mesh mould, obtains felt blanket;
(4) felt blanket obtains the flat felt of semi-finished product after by fast cooling shaping mesh mould molding;
(5) the flat felt of semi-finished product obtains deadening felt after die cutting die is die-cut.
The temperature of the heating described in step (3) is 180～200 ℃, and hot blast, from cottonseed cake bottom to blowing up, heats cottonseed cake.
The thickness of the felt blanket that step (3) obtains is the half of cottonseed cake thickness, and the object of forcing down half is the feature that occurs in forming process that for fear of cottonseed cake part material is many, causes collapsing and the phenomenon such as lamination.
The concrete steps of step (4) are: the felt blanket obtaining from baking oven heating mesh mould enters fast cooling shaping mesh mould, mesh patrix and mesh counterdie close and close, the rapid exhausting of suction opeing, so just form the draught head of mesh patrix and mesh counterdie, form the negative pressure cabin of mesh patrix and the malleation storehouse of mesh counterdie, between malleation storehouse and negative pressure cabin, just form like this air-flow, air moves to mesh patrix from mesh counterdie, the heat of the felt blanket between mesh patrix and mesh counterdie is taken away by air-flow like this, thereby realize the rapid cooling forming to felt blanket, obtain the flat felt of semi-finished product.
In step (4), the temperature in fast cooling shaping mesh mould is 3～7 ℃, and the time that felt blanket stops in fast cooling shaping mesh mould is 35～45 seconds.
Just completed the production of deadening felt part through four moulds, the coherent of whole process just completed the single part production cycle in 1 minute, realized supper-fast part and produced.
Compared with prior art, the present invention has the following advantages:
One, whole deadening felt production process completed in 1 minute, had realized supper-fast deadening felt and had produced, and had greatly improved production efficiency, reduce production costs, and the leading position in industry in this type of part level of production.
Two, eliminated the unnecessary energy loss for the second time felt blanket heating being produced in old explained hereafter, eliminate the second logistic that felt blanket in old technical process is transported to press workshop, so summary of the invention has reduced the production cost of part, this type of thermoforming part is produced towards low energy consumption, low-carbon (LC), environmental protection future development.
Three, in production, mould distribute heat is few, reduces shopwork temperature, improves circumstance.
Four, the present invention has wide market prospects.
