Description

A kind of knotless load-bearing net and its weaving method

technical field

The invention relates to the field of anti-drop load-bearing nets for manhole covers, in particular to a knotless load-bearing net and a weaving method thereof. the

Background technique

Manhole covers in cities are prone to fall accidents after being stolen or lost. At present, the more recognized prevention method is to set a load-bearing net under the manhole cover. fell into the manhole. In the process of load-bearing nets, the traditional way is to use multi-strand weft threads 4 to tie each other to form a net, and at the same time, according to the load-bearing strength requirements of the net, the multi-strand braided threads are twisted and braided to increase the strength. To form the braided weft 4. However, the net made by this process has the following disadvantages: First, because it is knotted into a net, it is difficult to process it quickly on the machine, and it will inevitably use a lot of labor. At the same time, each knot is tied by hand. Its strength is difficult to guarantee; second, when the net made by forming a net covers the goods, its protruding knots will damage the surface of the goods after being pulled in; third, multi-strand braided wires are twisted into braided weft The method 4 has a certain stretch and damage to the braided wire itself, and the actual strengthening effect is not as good as that directly braided with multiple strands. the

There is also an improved knotless net, as shown in a kind of knotless net and its weaving method announced by the domestic invention patent, which includes several net ropes one and two net ropes arranged at intervals, and net rope one and net rope two are both It is a two-strand braided structure, in which each net rope two passes between the two strands of the net rope one located in front of it, and then the two strands of the net rope two are separated and separated from the two strands of the net rope one respectively. Wrapped sideways to form twist points. The knotless net weaving method of this invention has improved efficiency, but this method must be completed with corresponding custom-made equipment, so the cost is relatively high, and his weaving method is one-time weaving The strength of multiple braided wires cannot guarantee the load-bearing requirements, so they can only be used as fishing nets. the

As a preference, the first braided thread, the second braided thread and the braided serif are all composed of a plurality of braided net ropes arranged in a natural circular arrangement. the

As a preference, the first braiding thread, the second braiding thread and the braiding serif are all braided at the same time by a plurality of braiding net ropes that compose them when braiding the braiding weft and the connecting weft of. the

As a preference, the knitting methods of the connecting weft yarn and the weaving weft yarn are both looped and knotted. the

In summary, the present invention has the following advantages:

A knotless load-bearing net and a weaving method thereof, comprising a braided wire I and a braided wire two, the braided wire I and the braided wire two are arranged at intervals, and the braided wire I and the braided wire two are respectively braided into Weaving weft, the knitting line one and the adjacent knitting line two are jointly woven into a connecting weft when intersecting, the weaving method of the connecting weft is the same as that of the weaving weft, and the connecting weft and the The weaving wefts together form a mesh body. The advantage of this weaving method is that the traditional knot design is cancelled, and the connecting weft is used instead, and the connecting weft and the weaving weft use the same weaving method, and the composition of the connecting weft and the weaving weft is the same, so that it can be used in ordinary The warp knitting machine is shaped at one time, and there is no need to customize special equipment to complete the process, which improves production efficiency and reduces the equipment cost of production investment; at the same time, because the principle of netting is the bridge connection of the same braiding wire method, so The strength of the net is also very high, and the local structure will not be too loose due to the overly complicated weaving structure; another advantage of using this weaving method is that the weft threads of the net are connected by the same weaving instead of knotting. , so that the net is relatively flat and will not cause damage to the surface of the object when covering the object.

In the present invention, preferably, the braided weft thread further includes a braided serif, and both the braided thread one and the braided thread two are braided around the braided serif. After adding the weaving serif, the bearing force of the weft weft in the longitudinal direction is increased, which increases the firmness of the net. the

In the present invention, it is preferred that the first braided thread, the second braided thread and the braided serif are all composed of a plurality of braided net ropes arranged in a natural circular arrangement. This increases the strength of the individual braided wires. the

In the present invention, the first braiding thread, the second braiding thread and the braiding serif are all woven simultaneously by a plurality of braiding net ropes that form them when weaving the braided weft and the connecting weft . In this way, the efficiency can be improved, and there is no need to weave the braided wire first and then weave the net as in the traditional craft. the

In the present invention, the knitting methods of the connecting weft and the weaving weft are preferably looped and knotted. With this most basic weaving method, the most basic warp knitting machine can be used for weaving, which reduces the cost and achieves reliable strength at the same time. the

Detailed ways

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

As shown in Figure 1, the present invention uses three rows of bars in the use of the bars of the warp knitting machine, which are respectively bar one 7, bar two 8 and serif bar 9, and the singular position of bar one 7 Woven thread one 1 is worn, and braided thread two 2 is worn on the even-numbered position of bar two 8, and braided serif 3 is all worn on all positions of serif bar 9. Among them, braided thread 1, braided thread 2 and braided serif 3 are all arranged side by side by multiple braided mesh ropes, and the number of braided mesh ropes arranged in parallel is about 7 to 20 each time, and the specific number depends on the braided mesh used. The material of the net rope is determined, and then the weaving of the net is completed through the following steps. the

Step 1, after the weaving starts, the braided thread one 1 of bar one 7 and the braided thread two 2 of bar two 8 and the braided serif 3 on the serif bar 9 at the corresponding position pass through warp knitting together The knotting action of the machine is knotted, and the formed braided loop knots are looped and connected to each other to form the braided weft 4. the

Step 2, after the length of weaving weft 4 meets the design requirements, bar one 7 moves half a bit to the right, bar two 8 moves half a bit to the left, and serif bar 9 does not move. At this time, weaving line one 1 and weaving Line two and 2 intersect, and the knitting of the connecting loop knot is jointly completed through the knotting action of the warp knitting machine, and the connecting loop knot is connected with the loop to form the connecting weft thread 5 . the

Step 3, after the length of the connecting weft 5 meets the design requirements, bar 1 7 continues to move half a bit to the right, bar 2 8 continues to move half a bit to the left, and the serif bar 9 continues to move. At this time, weaving line 1 1 Separate from braided wire two 2 and braided wire one 1 and braided wire two 2 exchange positions, the braided wire one 1 of bar one 7 and the braided thread two 2 of bar two 8 and the serif comb on the corresponding position The braided serifs 3 on the bar 9 are jointly knotted through the knotting action of the warp knitting machine, and the braided loop knots formed are looped and connected to each other to form the braided wefts 4 . the

Step 4: Repeat the knitting action from step 2 to step 3 until the bar of the warp knitting machine has finished its travel, bar 1 7 and bar 2 8 start to move in the opposite direction, and the action process is the same as step 2 and step 3. the

Step five, repeat steps two to four to complete the weaving cycle according to the size of the net. the

In step 6, the edge of the net is processed into a weaving net edge 6 with an edge beating machine. the
