Description

A method for weaving a four-layer rectangular knotless net

Technical Field

The invention relates to the technical field of braiding machines, in particular to a four-layer rectangular knotless net braiding method.

Background Art

Knotless net is a mesh fabric without knots, which is made of mesh wires or individual strands of mesh wires interwoven with each other. According to its structure, it can be divided into warp knitted mesh structure, braided mesh structure, twisted mesh structure, inserted twisted mesh structure, flat woven mesh structure and formed mesh structure. The wires in the net are connected, and it has the advantages of uniform force, tensile resistance, wear resistance, flat net body and impact resistance. It is not only used for fishing operations, but also widely used in safety protection, sports and leisure places;

At present, the weaving of knotless nets in China mainly relies on rapier looms and warp knitting machines. Rapier looms have the problems of low production efficiency and uneven quality, and the quality of fabrics is greatly affected by mechanical precision; warp knitted fabrics are made of looped yarns knitted in chains, the fabric is elastic, the mesh size will fluctuate within a certain range, and the curling of the yarn will cause partial strength loss. Relatively speaking, the knotless nets produced by two-dimensional weaving technology have small yarn buckling in the fabric structure and smaller strength loss. HeinzBerger, Harry Reiche l, Holm W and others proposed to use this weaving method to produce knotless nets, and gave several different styles of knotless net weaving cases, but their theory is difficult to solve the general weaving method of knotless nets with different numbers of mesh feet, and it is difficult to solve the problem of spindle interference during the mutual transformation of mesh feet and mesh knots;

At the same time, the spindle rails on the warp knitting machine do not have the effect of automatic lubrication when working, which causes the machine to need to be stopped for lubrication after working for a period of time, affecting the overall production efficiency.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in Fig. 1-15, the present invention provides a four-layer rectangular knotless mesh weaving method, which realizes the weaving and forming of the knotless mesh feet with the maximum number of strands of the four-slot angle wheel by determining the movement path of the spindles and the distribution of the spindles;

Eight yarns are selected for mesh foot weaving, and the orbital paths of mesh foot weaving and mesh knot weaving spindles are planned on the weaving base plate 1. At the same time, the orbits are numbered and changed in style to avoid interference between spindles at the intersections at any time, and the initial distribution plan of spindles with a feasible spiral trajectory is determined;

The mesh foot uses eight yarns for traditional cross-section weaving. The mesh knot is formed by cross-weaving of the yarns of the two mesh feet. The mesh knot structure is determined by the movement track of the weaving machine spindles and the initial distribution of the spindles.

When n four-slotted corner wheels are used to weave mesh feet, a maximum of 2n yarns can be woven. The two spindle tracks use a complementary spindle arrangement rule with a period of n to avoid interference between spindles during the weaving process.

When two adjacent mesh foot structures with n 4-slot corner wheels are weaving a mesh structure, the spindle arrangement on the two spindle tracks adopts a complementary spindle arrangement rule with a period of 2n, and the first n positions and the last n positions in each spindle arrangement period are complementary, when a single mesh foot is weaving, the spindles do not interfere with the adjacent mesh feet, and when the mesh knots are interwoven, the spindles do not interfere with each other.

During the process of converting the mesh feet into mesh knots, when the angle wheels drive all the mesh foot spindles to move to the required position consistent with the mesh knot weaving system, the state of the track change turntable located between two adjacent mesh foot tracks is adjusted to avoid interference between the spindles when the mesh feet are interwoven.

Research on the transformation method of mesh feet and knots:

The first step is to put the spindle in place. Figure 3 shows the initial weaving state of the mesh foot weaving system.

Among them, the solid spindles are circled with large circles. In order to make the spindle arrangement after the mesh foot weaving system in FIG3 move consistent with FIG12, the movement paths of spindles a and b should be changed to track 3 and track 4 respectively;

According to the weaving unit of FIG12, the spiral track knotless net weaving process of FIG4 to FIG12 is obtained, that is, before the corner wheel rotates, FIG4 is the initial state of the spiral track knotless net, and the spindle in each weaving unit is consistent with the state of FIG12 at the slot position; the two ends of the track unit (at the intersection 1 and 2) are disconnected, and run one step to obtain the weaving state of FIG5;

The second step is to realize track conversion. Figure 6 shows the weaving system after changing the state of the track change device at the intersections 3 and 4 (closing the middle track) and continuing to run 7 steps to complete the weaving of the net knots in the first half cycle. Turn the track change device at the intersections at both ends to close the two ends of the track, convert the net knot weaving system into the net foot weaving system shown in Figure 7, and run 1 step;

The track changing devices at the middle are rotated respectively and rotated to the initial state, so as to transform the weaving system into the initial state shown in FIG8 ;

Continue to rotate the track changing devices at both ends respectively, and run one step to transform the weaving system into the weaving state shown in FIG. 9 , where some of the horizontal web feet are transformed into vertical weaving;

Figure 10 shows a weaving system that changes the state of the track change device at the middle of the track and continues to run for 7 steps to complete the weaving of the net knots in the second half cycle. The track change device states at both ends of the track are closed and run for 1 step, and the net knot weaving system in the second half cycle is transformed into the net foot weaving system shown in Figure 11;

Finally, the track changing device in the middle is turned to transform the weaving system into the mesh foot weaving system shown in FIG12 to complete the weaving of a complete cycle of knotless nets. The above steps are repeated to obtain the weaving of spiral track knotless nets of different mesh sizes.

The weaving base plate 1 is provided with a plurality of groups of spindle rails 11, and the weaving base plate 1 serves as the core working area of the warp knitting machine. A mounting plate 12 is provided on the outer wall of the weaving base plate 1 near a group of spindle rails 11, and delivery pipes 13 are fixedly provided at both ends of the mounting plate 12. An end of the delivery pipe 13 away from the mounting plate 12 is connected with an oil delivery pipe 14, and an end of the oil delivery pipe 14 away from the delivery pipe 13 is inserted into the spindle rail 11, and the oil delivery pipe 14 is communicated with the inside of the spindle rail 11, and an oil inlet pipe 131 is installed on the top of the delivery pipe 13, and a one-way valve 132 is installed on the end of the oil inlet pipe 131 close to the delivery pipe 13. A horizontally arranged cross plate 2 is penetrated at the inner middle end of the mounting plate 12, and a rectangular groove 21 is penetrated at the middle end of the cross plate 2, and an arc groove 22 is provided at the diagonal of the rectangular groove 21. 1 is provided with a vertically arranged rotating rod 23 at the middle end, and a push block 24 arranged in a Y shape is fixedly provided at the upper end of the rotating rod 23, and the end of the push block 24 can be against the rectangular groove 21, and long rods 25 are fixedly provided at both ends of the cross plate 2, and a slider 26 is fixedly provided at the end of the long rod 25, and the slider 26 is slidably arranged in the mounting plate 12, and a piston rod 27 is fixedly provided at the end of the slider 26, and the end of the piston rod 27 away from the slider 26 is inserted in the conveying pipe 13 and fixed with a piston plate 28, and a protective cover 3 is fixedly installed at the bottom of the mounting plate 12, and the bottom of the rotating rod 23 is rotatably arranged in the protective cover 3, and a driving gear 33 is fixedly provided at one end of the rotating rod 23 located in the protective cover 3, and a vertically arranged driving shaft 31 is rotatably provided in the protective cover 3, and a fan-shaped gear 32 meshing with the driving gear 33 is fixedly provided on the driving shaft 31.

The protective cover 3 is fixedly provided with a vertically arranged connecting shaft 34 near the driving shaft 31, and a small gear 35 is fixedly provided on the connecting shaft 34. A large gear 36 meshing with the small gear 35 is fixedly provided on the driving shaft 31. A rotating shaft 41 is rotatably provided in the middle of the spindle track 11 on the weaving base plate 1, and a dial 4 is fixedly provided on the top of the rotating shaft 41. A pulley 37 is fixedly provided between the rotating shaft 41 and the connecting shaft 34, and a synchronous belt 38 is provided on the pulley 37 for common transmission.

Working principle: When the warp knitting machine is working, the dial 4 on the weaving base plate 1 will be driven to rotate. At this time, the rotating shaft 41 on the dial 4 will also work together, so as to cooperate with the pulley 37 and the synchronous belt 38 to drive the connecting shaft 34 to rotate. At this time, the connecting shaft 34 will drive the large gear 36 to rotate through the small gear 35, and the large gear 36 will drive the driving shaft 31 fixed thereto to rotate. At this time, the fan gear 32 fixed on the driving shaft 31 will intermittently drive the driving gear 33 engaged to rotate. At this time, the driving gear 33 will drive the top push block 24 to rotate. First, one end of the push block 24 will abut against the side wall of the rectangular groove 21, so that the push block 24 will push the cross plate 2 toward the side in contact with the rectangular groove 21. As the machine rotates, the cross plate 2 will move toward the side in contact with the rectangular groove 21. The rod 23 rotates continuously, and the side of the push block 24 that contacts the rectangular groove 21 will move into the arc groove 22. At this time, the other end of the push block 24 will abut against the other side of the rectangular groove 21, thereby pushing the cross plate 2 back to its original position, and so on and so forth. Driven by the rotating rod 23, the cross plate 2 will be driven to move back and forth continuously. At this time, the long rod 25 and the slider 26 on the cross plate 2 will push the piston rod 27 and the piston plate 28 to squeeze the lubricant in the delivery pipe 13 into the spindle track 11 through the oil delivery pipe 14. Subsequently, as the base at the bottom of the spindle slides in the spindle track 11, the lubricant will be brought into other positions of the track, thereby completing the purpose of automatic lubrication, improving the convenience of operation, ensuring the stability of the movement of the spindle base in the spindle track 11, and improving the service life.

At the same time, driven by the small gear 35 and the large gear 36, the rotation speed of the driving shaft 31 can be reduced. At the same time, the sector gear 32 drives the driving gear 33 to rotate, which can further control the rotation speed of the rotating rod 23, thereby reducing the working frequency of the piston rod 27 and the piston plate 28. In the case of automatic lubrication, the input of lubricating oil is controlled, the utilization of resources is improved, and excessive lubrication is prevented from affecting the overall working efficiency of the warp knitting machine spindle.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
