Weaving method of knotted mesh fabric

Technical Field

The invention relates to the technical field of fishing net weaving, in particular to a weaving method of knotted net-shaped fabric.

Background

At present, knotted fishing net machines are used for producing various net tools such as fishing nets, building safety nets, plant protection nets, bird prevention nets, sports nets and the like. In practical application, the amount of the knotted fishing net accounts for about 95 percent of the total amount of the net, and the type of the net for fresh water, mariculture and fishing is generally the knotted net.

The net sheet of the present knotted net device has single knot, double knot, U-shaped knot, etc. The single knot type is simple, only suitable for polyethylene multifilament, nylon multifilament etc. but easy slip knot, and is not suitable for the monofilament even more, and the U type knot is suitable for the monofilament, but the knot type is big, and the output is low when producing. Therefore, a new net with small net-sheet knot, non-slip knot and high yield is desired.

2) the upper hook reversely rotates clockwise or anticlockwise for 0.25-0.5 circles, in the process, the weft pushing plate moves upwards to lift and wind the weft in the upper hook to form weft loops, then the weft pushing plate moves downwards to reset, and the upper hook continuously rotates clockwise or anticlockwise for 0.5-0.25 circles until the hook tip of the upper hook aligns with the pore plate and stops;

3) the lower hook moves towards the upper hook and penetrates through the warp coil and the weft coil on the upper hook, at the moment, the lower hook moves to the position close to the pore plate, the pore plate guides the warp to wind in the lower hook, then the lower hook hooks the warp to penetrate through the warp coil and the weft coil, the warp is pulled out, and the warp is sleeved in the shuttle;

4) and (4) separating the warp loops and the weft loops by hooking motion to form knots initially, and then tensioning the knots under the action of a knot tensioning roller to complete knot tying.

As a specific embodiment, in step 1), the upper hook rotates around itself counterclockwise or clockwise for a total of 2 turns.

As a specific embodiment, the upper hook rotates clockwise or counterclockwise for 0.75 circles in step 2).

As a specific embodiment, the hole plate guides the warp thread to form 1 loop on the upper hook in the step 1); and 2) the weft ejection plate guides the weft to be hooked into 1 circle.

Compared with the prior art, the invention has the following beneficial effects:

in the weaving process, the pore plate is adopted to guide the warp threads to form 1 circle on the upper hook, and the weft jacking plate is adopted to guide the weft threads to form 1 circle on the upper hook, so that the knot forming is more convenient, the action in the knot forming process is compact, and the working efficiency is high; meanwhile, the net knots woven by the method have small knot shapes, cannot slip knots and have high yield.

Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1 to 8, a weaving method of a knotted mesh fabric adopts a weaving machine comprising an upper hook 1, a lower hook 2, a pore plate 3, a weft pushing plate 4, a shuttle 5 and a wire coil, wherein warp threads 6 penetrate through the pore plate 3, and weft threads 7 are wound in the wire coil. In this example, the method comprises the steps of:

1) when the operation surface looks backward, the upper hook 1 is reset to the right or left of the hook point of the upper hook, and the hook point of the rear upper hook 1 swings to one side of the pore plate 3 and rotates counterclockwise by 0.25-0.5 circle, in the process, the pore plate 3 guides the warp 6 to wind in the upper hook 1, and the upper hook 1 hooks the warp 6 and then rotates counterclockwise by 1.75-1.5 circles to form a warp coil; in the initial position, the pore plate 3 is at a lower position relative to the upper hook in the up-down direction, the upper hook 1 swings to the position that the upper hook 1 is reset to the right of the hook tip of the upper hook when viewed from the operation surface to the machine, the pore plate 3 guides the warp 6 to move upwards when the upper hook 1 rotates, as shown in fig. 1, the pore plate 3 moves to the upper part of the left side of the upper hook 1 and then winds the warp 6 in the upper hook 1, and then the pore plate 3 is reset downwards, as shown in fig. 2, the upper hook 1 continues to drive the warp 6 to rotate anticlockwise to form warp loops, wherein the upper hook 1 rotates anticlockwise for 2 loops altogether, and of course, the upper hook 1 can also form warp loops in a clockwise rotation mode;

2) the upper hook 1 stops after rotating counterclockwise for 2 circles, as shown in figure 3, and then rotates clockwise for 0.25-0.5 circles, in the process, the weft thread 7 is lifted and wound in the upper hook 1 by the upward movement of the weft ejecting plate 4 to form a weft thread loop, as shown in figure 4, and then the weft ejecting plate 4 moves downwards to reset, and the upper hook 1 stops after continuing to rotate clockwise for 0.5-0.25 circles, and the hook tip of the upper hook aligns with the orifice plate, as shown in figure 5, wherein the upper hook 1 rotates clockwise for 0.75 circles;

3) the lower hook 2 moves towards the upper hook 1 and penetrates through the warp thread loop and the weft thread loop on the upper hook 1, at the moment, the lower hook 2 moves to the vicinity of the pore plate 3, the pore plate 3 guides the warp thread 6 to wind in the lower hook 2 from left to right (seen from the operation surface to the back of the machine), as shown in fig. 6, the warp thread 6 can also wind in the lower hook 2 from right to left, as shown in fig. 7, the lower hook 2 hooks the warp thread 6 to pass through the warp thread loop and the weft thread loop, then pulls out the warp thread 6, and sleeves the warp thread 6 in the shuttle 5, as shown in fig. 8;

4) the upper hook 1 moves to separate the warp loops and the weft loops to form knots initially, and then the knots are tightened under the action of a tightening roller (not shown in the figure) to finish knotting.

Here, the hole plate guides the warp thread to make 1 turn on the upper hook in step 1), and the top weft plate guides the weft thread to make 1 turn on the upper hook in step 2).

According to the weaving method, the pore plate is adopted to guide the warp threads to be hooked into 1 circle, and the weft jacking plate is adopted to drive the weft threads to be hooked into 1 circle, so that the knot forming is more convenient, the action in the knot forming process is compact, and the working efficiency is high; meanwhile, the net knots woven by the method have small knot shapes, cannot slip knots and have high yield.
