Disclosure of Invention

In view of the above, the present invention is directed to a recycling apparatus for waste nonwoven fabric, which can recycle the cut part of the nonwoven fabric, resulting in less waste.

In order to solve the technical problem, the technical scheme of the invention is as follows: the utility model provides a non-woven fabrics waste material reuse equipment, includes the screw extruder one that is used for supplying with the master batch, the lateral wall department of screw extruder one has seted up the feed supplement mouth, the feed supplement mouth with the inner chamber of screw extruder one is linked together, the side of screw extruder one is provided with screw extruder two, the discharge gate of screw extruder two with the feed supplement mouth is linked together.

Through the technical scheme, during use, the cut part of the non-woven fabric is placed into the feed inlet of the screw extruder II, the cut part of the non-woven fabric is heated to a molten state by the screw extruder II, and the non-woven fabric is fed into the screw extruder I through the feeding port, so that waste is reduced, and the production cost is reduced.

Preferably, the second screw extruder is parallel to the first screw extruder, a bent pipe is arranged at a discharge port of the second screw extruder, and the bent pipe is connected with the feeding port.

Through above-mentioned technical scheme, screw extruder one is parallel with screw extruder two-phase, and the non-woven fabrics fertilizer reuse equipment occupation space that so sets up is less. The second screw extruder can feed the molten raw material generated by heating the waste into the first screw extruder through a bent pipe.

Preferably, the surface of the bent pipe is coated with heat-insulating asbestos.

Through above-mentioned technical scheme, the heat preservation asbestos is used for keeping warm to the bending tube for the difficult cooling hardening of the inside melting form raw materials of bending tube.

When the waste material passes through the carding knife, the carding knife can be used for carding the waste material, so that the waste material is not easy to knot. When the waste materials are knotted, the knife edge of the carding knife can be used for cutting off the knot, and the knotted waste materials cannot easily plug the feed inlet of the screw extruder II.

Preferably, the carding knife comprises a housing hinged on the second screw extruder, an elastic piece connected with the housing and the second screw extruder, a cutting edge connected with the second screw extruder in a sliding manner, and a driving mechanism used for driving the cutting edge to slide along the vertical direction; an opening is formed in the side wall of the outer cover, which is far away from the screw extruder II, two carding edges are symmetrically arranged on two sides of the opening, and cutting edges of the two carding edges are abutted tightly; the cutting edge is arranged inside the outer cover, and the cutting edge of the combing edge faces to one side of the opening.

Through above-mentioned technical scheme, the carding sword blade that is located the opening both sides supports tightly each other, so when the waste material passes from carding sword, the carding sword can comb the waste material for the waste material is difficult for knoing. When the waste material knotting condition occurs, the two carding blades are matched to cut the knot end, so that the feed inlet of the screw extruder II is not easily blocked by the knotted waste material. When the waste material knotting condition is serious and the combing knife can not completely cut the knot, the knot can drive the outer cover to rotate towards one side of the screw extruder II. When the cutting edge positioned in the inner part of the outer cover is contacted with the carding edge, the cutting edge can push the carding edge to the two sides. When the cutting edge is exposed between the two combing edges, the cutting edge is controlled by the driving mechanism to reciprocate along the vertical direction so as to cut open the knot. The cutting blade can conveniently cut the knot in the process of reciprocating motion along the vertical direction, so that the feed inlet of the screw extruder II is not easily blocked by knotted waste materials. When the knot is cut open, the elastic piece drives the outer cover to rotate towards the side far away from the screw extruder II, so that the cutting edge gradually retracts into the outer cover.

Preferably, a tearing plate is hinged to the joint of the carding edge and the outer cover, and tearing teeth are arranged on the tearing plate close to the side wall of the carding edge; the carding blade is provided with a through hole in a penetrating mode, and when the tearing plate is abutted to the carding blade, the tearing teeth penetrate through the through hole.

Through the technical scheme, when the outer cover rotates towards one side of the screw extruder II, the cutting blade is gradually close to the tearing plate. When the cutting edge is abutted against the tearing plate, the cutting edge can drive the tearing plate to rotate towards one side of the carding edge. When the tear-off plate is in contact with the carding edge, the tear-off teeth pass through the through-holes and catch the waste material. Later the cutting edge can push away tearing the board and combing the sword to both sides, and it can tear the waste material to tear the tooth to weaken the degree of knoing of waste material, make the knot of waste material can be more easily cut open by the cutting edge.

Preferably, a shifting lever is arranged on the side wall of the tearing plate, which is away from the combing blade, and the shifting lever is abutted to the cutting blade.

Through the technical scheme, when the outer cover and the cutting edge rotate relatively, the cutting edge can drive the tearing plate to comb the edge to rotate through the deflector rod.

Preferably, a protruding block is arranged on the side wall of the cutting edge, and the protruding block is abutted to the side wall, far away from the opening, of the shifting lever.

Through above-mentioned technical scheme, the lug of cutting sword lateral wall department keeps away from open-ended lateral wall with the driving lever and offsets, so the cutting sword can more conveniently order about the driving lever around the pin joint and rotate.

Preferably, the driving mechanism comprises a driving motor and a cam arranged on an output shaft of the driving motor, and the outer edge of the cam is abutted against the bottom of the cutting edge.

Through above-mentioned technical scheme, driving motor during operation drive cam rotates, can be with cutting edge periodic jack-up when the cam rotates.

Preferably, the inner wall department of dustcoat is provided with travel switch one and travel switch two, the lateral wall department of cutting edge is provided with the trigger block, works as the trigger block with travel switch one collides when touching, travel switch one will driving motor closes, works as the trigger block with travel switch two collides when touching, travel switch two will driving motor opens.
