[0002] With the popularity of non-woven fabrics, the demand for non-woven fabrics increases year by year, and a large number of non-woven fabric production equipment are put into production. Among them, the feeding device of the needling machine is an essential part of the production line. The feeding device of the needling machine is located between the lapping machine and the needling machine and is used to compress the lap layer output by the lapping machine and then feed it into the needling machine for needling. The feeding device generally has an upper conveying curtain and a lower conveying curtain. An included angle is formed between the two conveying curtains for clamping the lap layer, and by extending the lower conveying curtain and enabling one end thereof to rotate, it is convenient to connect the output port of the lapping machine. However, since the positions of the output ports of different models of lapping machines are different, if the position of the output port is too low, the inclination gradient of the lower conveying curtain will be greater, and the lap layer will enter the included angle between the two conveying curtains obliquely. Although the lap layer can be fed into the needling machine horizontally by adjusting the different conveying speeds between the upper and lower conveying curtains, it is ultimately obstructive to the feeding of the lap layer, and once the speed difference adjusted is too large, the lap layer may be damaged.

The upper and lower triangular members 23 and 33 are symmetrically arranged vertically and define a gap between them for the passage of the laying layer. The upper triangular member 23 forms an acute angle at one end of the upper conveyor curtain 2, and the lower triangular member 33 forms an acute angle at one end of the lower conveyor curtain 3.

[0020] In this embodiment, the lower conveying curtain 3 and the connecting conveying curtain 4 are respectively driven to rotate simultaneously by a main drive motor 7 installed on the wall panel 1 and located below the lower conveying curtain 3. The main drive motor 7 is fixedly installed on one side wall panel 1 through a main drive motor reduction box 71. The main drive motor reduction box 71 is composed of a main drive motor reduction box output shaft 72. A main drive wheel 73 is fixed on the main drive motor reduction box output shaft 72. The main drive wheel 73 drives the lower conveying curtain 3 and the connecting conveying curtain 4 to rotate respectively through a main drive chain 74; the lower conveying curtain 3 includes a lower conveying curtain driven roller 31 rotatably supported between the two wall panels 1 and a lower conveying curtain active roller 32 rotatably supported between the two wall panels 1. The two ends of the lower conveying curtain driven roller 31 are respectively rotatably mounted with the corresponding wall panel 1 through a lower conveying curtain driven roller bearing 311, and the two ends of the lower conveying curtain active roller 32 are respectively rotatably mounted with the corresponding wall panel 1 through a lower conveying curtain active roller bearing 322. One end portion of the aforementioned connecting conveying curtain active roller 42 is provided with a lower conveying curtain active roller transmission wheel 321; the aforementioned connecting conveying curtain 4 includes a pair of connecting conveying curtain mounting plates 41, a connecting conveying curtain active roller 42 which is rotatably mounted with the corresponding connecting conveying curtain mounting plate 41 through a connecting conveying curtain active roller bearing 422, and a connecting conveying curtain driven roller 43 which is rotatably mounted with the corresponding connecting conveying curtain mounting plate 41 through a connecting conveying curtain driven roller bearing 431. One end portion of the aforementioned connecting conveying curtain active roller 42 is provided with a connecting conveying curtain active roller transmission wheel 421, and the aforementioned connecting conveying curtain active roller transmission wheel 421, the lower conveying curtain active roller transmission wheel 321 and the main driving wheel 73 are connected by a main driving chain 74 for transmission, and the two ends of the aforementioned connecting conveying curtain active roller 42 are respectively rotatably supported on the wall panels 1 on both sides; the aforementioned rotation driving mechanism 5 is respectively mounted on both sides of the connecting conveying curtain mounting plate 41, and one end of the aforementioned rotation driving mechanism 5 is hinged to the middle part of the corresponding connecting conveying curtain mounting plate 41, and the other end is hinged to the corresponding wall panel 1.

[0021] Furthermore, the aforementioned rotary drive mechanism 5 includes a worm gear box 51, a screw 52 driven by the worm gear box 51, a worm gear box seat 53 hinged to the middle of the corresponding conveyor curtain mounting plate 41, and a screw hinge plate 54 fixed on the corresponding wall panel 1. The worm gear box 51 is installed on the worm gear box seat 53, one end of the screw 52 is hinged to the screw hinge plate 54, and the other end extends upward after passing through the worm gear box 51 and the worm gear box seat 53.

[0022] Please continue reading Figure 1 、 Figure 2, before use, first adjust the worm and gear box 51 of the aforementioned rotary drive mechanism 5 to make the worm and gear box 51 lift along the screw rod 52. During the lifting process, the aforementioned connecting conveying curtain 4 rotates between the wall panels 1 around the connecting conveying curtain driving roller 42 until the free end of the connecting conveying curtain 4 is connected to the corresponding output port of the cross-lapper; the cross-lapped layer 8 output from the cross-lapper is conveyed to between the lower conveying curtain 3 and the upper conveying curtain 2 along the free end of the connecting conveying curtain 4. The lower surface of the cross-lapped layer 8 contacts the lower conveying curtain 3, and the upper surface contacts the upper conveying curtain 2; then adjust the rotational speeds of the aforementioned main drive motor 7 and the upper conveying curtain drive motor 6 to make the transmission speed of the lower conveying curtain 3 less than the transmission speed of the upper conveying curtain 2. At this time, the cross-lapped layer 8 is horizontally conveyed to one end where the lower conveying curtain 3 and the upper conveying curtain 2 approach under the action of the speed difference between the lower conveying curtain 3 and the upper conveying curtain 2, and is extruded and conveyed to the needle punching machine after passing through the upper triangular member 23 and the lower triangular member 33. Since the connection with the cross-lapper is realized by adding the connecting conveying curtain 4, the structure of extending the length of the lower conveying curtain 3 in the prior art is abandoned, effectively avoiding the problem that the cross-lapped layer cannot be horizontally input due to the too large inclination angle of the lower conveying curtain 3 and the too large speed difference between the upper conveying curtain 2 and the lower conveying curtain 3.
