Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses an environment-friendly non-woven needle loom, including frame 1, 3 hydraulic stretching cylinders 6 along the setting of perpendicular to frame roof of fixedly connected with on the 1 roof of frame, actuating lever 5 of expansion end fixedly connected with of each hydraulic stretching cylinder 6, actuating lever 5 sets up along the 1 roof direction of perpendicular to frame. One end of the driving rod 5, which is far away from the hydraulic telescopic cylinder 6, is connected to a rectangular needling board 4, and one side of the needling board 4, which is far away from the driving rod 5, is provided with a plurality of felting needles 42 with barbed hooks which are arranged in a rectangular array.

Referring to fig. 1 and 3, a rectangular mesh stripping plate 2 with two ends fixedly connected to the frame 1 is arranged below the needle plate 4, and a rectangular mesh supporting plate 3 with two ends fixedly connected to the frame 1 is arranged below the mesh stripping plate 2. The mesh stripping plate 2 and the mesh supporting plate 3 are both provided with through holes 21, and the through holes 21 correspond to the felting needles 42 one by one. In the needling process, the fiber web is positioned between the screen stripping plate 2 and the screen supporting plate 3, the felting needles 42 move downwards to penetrate through the through holes 21 to be inserted into the fiber web, then the felting needles 42 move upwards, the felting hooks on the felting needles 42 drive the fibers on the surface of the fiber web to pull the fibers along the direction vertical to the length direction of the fibers, so that the fibers are displaced up and down, and the fibers displaced up and down generate certain extrusion on the fiber web, so that the fibers in the fiber web are close to each other and compressed.

Referring to fig. 1 and 2, the interior of the needle plate 4 is hollow to form an air chamber 41, a hollow cylindrical connecting pipe is fixedly connected to the outer wall of the needle plate 4, an air inlet hose 101 is sleeved on the connecting pipe, and the air inlet hose 101 is clamped by a clamp. One end of the air inlet hose 101, which is far away from the connecting pipe, is connected with an air blower 10, and the air inlet hose 101 is communicated with an air outlet of the air blower 10. The outer wall of the frame 1 is fixedly connected with a supporting plate 11 for placing the blower 10. The inside of the puncture needle 42 on the puncture plate 4 is provided with a channel 421 along the length direction of the puncture needle 42, and the channel 421 is communicated with the air cavity 41. The puncture needle 42 is also provided with 3 rows of 12 air outlets 422 along the length direction of the puncture needle 42, and the air outlets 422 are communicated with the channel 421. During the needling process, the blower 10 blows air into the air cavity 41 through the air inlet hose 101, and the air flow passes through the channel 421 in the needle 42 and flows out from the air outlet 422 to blow air to the fiber web between the web peeling plate 2 and the web supporting plate 3, so that the broken fibers are separated from the fiber web.

Referring to fig. 1 and 2, a rectangular collecting box 7 with an open top is arranged below the screen supporting plate 3, the width of the collecting box 7 is larger than or equal to that of the screen supporting plate 3, and the top of the collecting box 7 is tightly attached to the screen supporting plate 3. Because the fibers are lighter in weight in the process of collecting broken fibers and can flap in other directions after being blown by airflows from other directions, the collecting box 7 is tightly attached to the net supporting plate 3, and the possibility that the broken fibers flap out of a gap between the collecting box 7 and the net supporting plate 3 can be reduced. An exhaust pipe 8 is inserted into the right side wall of the collecting box 7, one end of the exhaust pipe 8, which is far away from the collecting box 7, is connected with an exhaust fan 9, and the exhaust pipe 8 is connected with an exhaust opening of the exhaust fan 9. The exhaust fan 9 is arranged outside the frame 1. After blowing the broken fibres out of the web, the suction fan 9 starts to suck air so that the broken fibres are attracted downwards and thus sucked into a collecting box 7 located below the trawl board 3 so that the broken fibres can be collected in a concentrated manner.

Referring to fig. 4, the exhaust pipe 8 is divided into two sections, the two sections of the exhaust pipe 8 are connected by two connecting discs 81 arranged oppositely, and the two connecting discs 81 are both perpendicular to the exhaust pipe 8. The center of the connecting disc 81 is provided with an air hole communicated with the exhaust pipe 8, four corners of the connecting disc 81 are provided with four mounting holes, and the two connecting discs 81 are connected by penetrating through the mounting holes through bolts. One of the lands 81 is further provided with 2 bumps 812, and the other land 81 is provided with a slot 813 for the bumps 812 to be inserted. Because in the convulsions process, cracked fibre probably gets into in the exhaust column 8, can conveniently break off exhaust column 8 through connection pad 81 connection, regularly clear up the inside fibre residue of exhaust column 8. The opposite sides of two connection pads 81 all are equipped with the slot 811 of cross section for the rectangle, and two slots 811 surround and form the socket, and the socket interpolation is equipped with filter 82. The filter plate 82 is additionally arranged, so that sucked fibers can be blocked at the filter plate 82, and the possibility that the fibers enter a fan to cause damage to the fan is reduced.

The implementation principle of the embodiment is as follows: the blower 10 blows air into the air cavity 41 through the hose, the air flow flows out from the air outlet 422 through the channel 421 in the needle 42 and blows air to the fiber web on the net supporting plate 3, so that the broken fibers are separated from the fiber web, meanwhile, the air draft device starts to exhaust air, the broken fibers are attracted downwards, and then the broken fibers are sucked into the collecting device below the net supporting plate 3, the broken fibers can be collected in a centralized mode, and the possibility that the broken fibers scatter into the air is reduced.

The embodiments of the present invention are the preferred embodiments of the present invention, and the protection scope of the present invention is not limited by this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
