[0002] In the actual production process, a weaving production equipment is often used to interweave biodegradable warp threads and weft threads to produce biodegradable dust-proof nets, so as to produce biodegradable dust-proof nets quickly and in batches. During the weaving process, generally, the warp thread combing block and the weft thread combing block are respectively installed on the warp thread driving plate and the weft thread driving plate, and the thread needles are installed on the needle plate. On the one hand, the warp thread driving plate and the weft thread driving plate are respectively driven by a transverse movement driving mechanism to move horizontally back and forth. On the other hand, a swing driving mechanism composed of multiple cylinders or motors is used to drive the warp thread driving plate and the weft thread driving plate to swing horizontally back and forth and drive the needle plate to move up and down, so as to complete the weaving of the dust-proof net. The structure of the existing biodegradable dust-proof net production equipment is relatively complex. Especially, its swing driving mechanism requires multiple cylinders or motors to complete, with poor running stability, high input and maintenance costs, large floor area, low intensification degree, and it is difficult to meet the actual use requirements.

Secondly, the transverse movement driving mechanism can be used to drive the warp thread driving plate and the weft thread driving plate to move horizontally back and forth respectively. And because the swing can be decomposed into a horizontal component movement and a vertical component movement, combined with the swing driving mechanism, the swing cam and the lifting cam can be rotated simultaneously by the same swing motor, so as to drive the warp thread driving plate, the weft thread driving plate and the needle plate on the swing arm to swing back and forth, and further realize the horizontal back-and-forth swing of the warp thread driving plate and the weft thread driving plate and the up-and-down movement of the needle plate.

First, the woven dust-proof net can be pulled out from one side of the upper end of the discharging plate by the discharging mechanism and drive each warp and weft to feed; secondly, the transverse movement driving mechanism can drive the warp driving plate and the weft driving plate to reciprocate horizontally respectively. And since the swing can be decomposed into a horizontal component motion and a vertical component motion, combined with the swing driving mechanism, the swing cam and the lifting cam can be rotated simultaneously by the same swing motor, so as to drive the warp driving plate, the weft driving plate and the needle plate on the swing arm to swing reciprocally, thereby realizing the lateral reciprocating swing of the warp driving plate and the weft driving plate and the up and down lifting movement of the needle plate.

The woven dust-proof net is tightly clamped between the discharging rollers 92, and the discharging motor 91 drives the discharging rollers 92 to rotate to convey the dust-proof net outwards.

[0033] The working principle of the biodegradable dust-proof net of the present invention: First, the woven dust-proof net is tightly clamped between the discharging rollers 92. The discharging motor 91 drives the discharging rollers 92 to rotate to convey the dust-proof net outwards, and drives each warp thread and weft thread that has not been woven to feed respectively. One feeding mechanism 2 is used to provide multiple warp threads from above, and the other feeding mechanism 2 is used to provide multiple weft threads from above. Then, in combination with Figures 2 to 4 , the warp threads pass through the warp holes 41 and feed the thread needles 30 downwards to form loops of the warp threads, and the weft threads pass through the weft thread tubes 50 and feed the thread needles 30 downwards to reciprocally pass through two adjacent warp threads; specifically, the process of forming loops of the warp threads is as Figure 4 shown. In the first step, the swing motor 81 of the swing drive mechanism 8 drives the lifting cam 83 to rotate, driving the thread needles 30 on the needle plate 3 to rise from the needle grooves 60. At this time, the needle tongues 301 turn downwards to form an angle with the sides of the thread needles 30, and the old warp loops are located between the needle tongues 301 and the thread needles 30. The transverse movement drive mechanism 7 drives the weft thread transverse movement plate 5 to transversely move the weft thread through the angle between the old warp loops and the warp threads that have not yet formed loops to achieve the action of the weft thread passing through the warp loops; in the second step, the swing motor 81 of the swing drive mechanism 8 drives the swing cam 82 to rotate to drive the swing arm 11 to swing laterally and drives the warp thread drive plate 4 to transversely move through the transverse movement drive mechanism 7, winding the warp threads on the warp thread drive plate 4 around the needle hooks 300; in the third step, the swing motor 81 of the swing drive mechanism 8 drives the lifting cam 83 to rotate, driving the thread needles 30 on the needle plate 3 to descend from the needle grooves 60. At this time, the needle tongues 301 turn upwards under the action of the front end of the old warp loops to close the needle hooks 300 until the thread needles 30 are lower than the old warp loops to complete the loop withdrawal; in the fourth step, under the pulling of the discharging mechanism 9, the woven dust-proof net is pulled outwards from one side of the upper end of the discharging plate 6. At this time, the warp threads hooked downwards in the second step form new warp loops. The swing motor 81 of the swing drive mechanism 8 drives the lifting cam 83 to rotate, driving the thread needles 30 on the needle plate 3 to rise from the needle grooves 60. Under the push of the new warp loops, the needle tongues 301 turn downwards to form an angle with the sides of the thread needles 30 until the new warp loops are located between the needle tongues 301 and the thread needles 30. Thus, the forming action of an entire warp loop is completed. Repeating the above first to fourth steps can perform the forming action of the next warp loop.
