Technical Field

The invention relates to the technical field of electric wire production, in particular to an electric wire plastic-coating production system.

Background

The wire is a product in which a plastic insulating layer is coated on a metal monofilament or a multi-strand metal core wire. A head for producing an electric wire is generally called a squeeze coating head, and an electric wire extrusion coating molding (also called electric wire overmolding) process: the molten plastic enters the machine head from the machine barrel through the grid plate, and the core wire enters the machine head from the wire feeding device. The melting material is uniformly coated on the core wire in the machine head, and the required product is obtained by cooling and coiling under the action of the traction device.

The plastic particles contain partial powder, and other substances such as dust, scrap iron and the like can be mixed in the powder. When plastic particles enter the interior of the extruder from the feed hopper, the impurities can enter the extruder and be melted, and the quality of the extruded electric wire is affected. Or a part of powder impurities which cannot be melted can be embedded into the extruded cable, thereby reducing the quality of the electric wire.

Disclosure of Invention

The invention aims to provide a wire plastic coating production system which can remove impurities from plastic particles entering an extruder and avoid the influence of the impurities entering the extruder on the extrusion quality of a wire.

In order to achieve the purpose, the invention adopts the following technical scheme:

a wire plastic-coating production system comprises an extruder and a plastic particle dust removal mechanism, wherein the plastic particle dust removal mechanism comprises a storage box and an impurity removal box, the storage box is positioned on one side of the extruder, and the impurity removal box is positioned above a machine barrel of the extruder;

the impurity removing box comprises a vertical feeding cylinder and a conical impurity removing cylinder arranged below the feeding cylinder; the feeding cylinder comprises an outer cylinder, a middle cylinder and an inner cylinder, wherein the inner cylinder is provided with an air hole, a primary impurity removal channel is formed between the inner cylinder and the middle cylinder of the feeding cylinder, an air outlet channel is formed between the outer cylinder and the middle cylinder, and a plastic particle channel is formed on the inner side of the inner cylinder; the impurity removing barrel comprises a plurality of impurity removing plates, the impurity removing plates surround to form a conical impurity removing barrel, impurity removing gaps are formed between adjacent impurity removing plates, a magnetic plate used for blocking the impurity removing gaps is arranged below the impurity removing gaps, the top ends of the impurity removing gaps are communicated with the bottom of the plastic particle channel, the tail ends of the gaps are communicated with discharge pipelines, and the discharge pipelines are communicated with a machine barrel of the extruder; a lower air pipe with a U-shaped cross section is fixed below the magnetic plate, the top of the upper air pipe is communicated with the air inlet channel, an inverted U-shaped upper air pipe is arranged above the impurity removal gap, the bottom of the upper air pipe is communicated with the bottom of the lower air pipe, the top of the upper air pipe is communicated with the bottom of the air outlet channel, and the top of the air outlet channel is communicated with a dust removal bag;

the storage box is communicated with a high-pressure air pump, and the discharge end of the storage box is communicated with the plastic particle channel through a feeding pipeline.

The principle of the scheme is as follows:

in the plastic granules passageway of an edulcoration section of thick bamboo was blown to the plastic granules of storage incasement to high compression pump, plastic granules whereabouts under the action of gravity, dust and iron fillings impurity among the plastic granules then get into once through the wind hole in the edulcoration passageway, this process is the edulcoration to plastic granules for the first time.

After the plastic granules after the impurity removal for the first time fall to the bottom of the plastic granules channel, the plastic granules enter the impurity removal gap below the plastic granules and move in the inclined impurity removal gap, the magnetic plate is in contact with the plastic granules, and the residual iron chips on the plastic granules are adsorbed by the upper surface of the magnetic plate. In the air current of downward motion gets into each leeward in the edulcoration passageway of once, iron fillings in the air current are adsorbed by the lower surface of magnetic sheet, and the air current of detaching iron fillings continues to move in the leeward, takes away the remaining dust on the plastic granules in the edulcoration gap, and this process is the secondary edulcoration. The airflow which takes away the dust enters the air outlet channel again, and the airflow moves upwards in the air outlet channel and finally the dust is removed in the dust bag.

This scheme of adoption can reach following technological effect:

1. carry out impurity removal and edulcoration gap and carry out the edulcoration of second time to plastic granules through an edulcoration passageway, plastic granules edulcoration is effectual, and in plastic granules after the edulcoration got into the barrel of extruder, the extrusion quality of impurity influence electric wire in the plastic granules can be avoided.

2. Set up impurity removal passageway on the one hand and can play preliminary edulcoration effect to plastic granules, on the other hand, high compression pump blows plastic granules and a large amount of wind to the plastic granules passageway in, if plastic granules and wind directly get into in the edulcoration gap, plastic granules can pass through fast in the edulcoration gap under the effect of air current, thereby it is relatively poor to lead to the edulcoration effect of plastic granules in the edulcoration gap, once impurity removal passageway can lead away the wind that gets into in the plastic granules passageway, consequently a large amount of wind gets into once in the impurity removal passageway rather than getting into in the impurity removal gap, thereby make plastic granules slow down at the interior velocity of motion of impurity removal gap, the edulcoration is effectual.

3. The air current when the secondary edulcoration derives from the air current of primary edulcoration, and the dust after the edulcoration divides with iron fillings and collects, is convenient for carry out the reutilization to iron fillings.

Further, the bottom of the plastic particle channel is provided with a conical guide plate. After plastic particles moving in the plastic particle channel fall to the bottom of the plastic particle channel, the plastic particles can automatically enter the peculiar smell discharge gap under the action of the conical guide plate, so that the plastic particles are prevented from being accumulated at the bottom of the plastic particle channel and being difficult to enter the impurity removal gap.

Further, the storage case is located the oblique below of edulcoration case. The storage box is located lower position, and the people of being convenient for supplements the plastic granules in the storage box in lower department.

Further, the feeding cylinder is connected with a supporting mechanism. The supporting mechanism can support the feeding cylinder.

Furthermore, the supporting mechanism comprises an anchor ear fixed on the outer wall of the outer cylinder of the feeding cylinder and a vertical supporting frame fixed on the anchor ear. During actual installation, the support frame can be supported on the ground, and the support frame can also be supported on the extruder, so that the feeding cylinder is vertically supported.

Further, the number of the dust removal bags is one. The dust removal effect can be achieved by only adopting one dust removal bag.

Further, the number of the dust removal bags is at least three. Because the air outlet channel is annular, more than three dust removal bags have better dust removal effect.

Further, the magnetic plate can be detachably connected to the bottom of the impurity removal gap. When the iron filings adsorbed on the magnetic plate are more, the magnetic plate can be detached to clean the iron filings on the magnetic plate.

Furthermore, the bottom of the lower air duct is detachably connected with a plywood. When the magnetic plate needs to be detached, the magnetic plate can be detached by opening the opening plate.

Further, the discharge pipelines are all obliquely arranged. When the plastic granules who accomplishes the edulcoration move in the ejection of compact pipeline that the slope set up, can play the effect of speed reduction and buffering, speed too big when avoiding plastic granules to get into in the barrel of extruder.
