Description
Technical Field
The invention belongs to the technical field of warp knitting machines, and relates to a novel warp knitting machine for knitting a grass-binding net.
Background
The grass binding net is a large mesh (hole) fabric for binding plants such as straw, pasture, etc., and is named because of its use function. The grass tying net is a warp knitting fabric, also called a knotless fishing net, and is generally produced by knitting with a warp knitting machine. The grass bundling net has the structure comprising several parallel warp knitting chains and weft inserted to connect the longitudinal warp knitting chains to form netted fabric. The straw bundling net has the structural characteristics that the braiding wires are thicker (the machine number is high), the meshes are large, and the distance between transverse braiding chains and the distance between longitudinal braiding chains (meshes) are large, and the maximum is one inch.
Fig. 1 and 2 show a latch needle or a compound needle single needle bar warp knitting machine adopted in the current production of a grass-binding net, and the core structure of the latch needle or compound needle single needle bar warp knitting machine is a looping device, and concretely comprises a knitting needle 1 (latch needle or compound needle, 1 is a compound needle in fig. 1 and comprises 1-1 groove needles and 1-2 needle cores), a looper (needle) plate 2, a subsidence 3 and a guide bar 4 motion device, and the knitting needle, the looper (needle) plate, the subsidence and the guide bar (yarn guide needle) are also called looping parts.
For warp knitting machines that knit strapped grass meshes, bar 4 is again composed of a knitting chain bar 4-1 and a weft insertion bar 4-2. The guide bar 4 swings along the front and back direction (shown in figure 1) of the whole machine and linearly and reciprocally moves transversely along the left and right direction (shown in transverse figure 2) of the whole machine (a traversing device 10, shown in figure 2), the swinging and traversing of the knitting chain guide bar 4-1 realizes the yarn padding of knitting yarns on the knitting needles 1, and then the knitting yarns are looped under the action of the loopers 2 to form knitting chains; for the weft insertion guide bar 4-2, knitting yarns do not need to be looped, only the back of the knitting needle 1 is required to be transversely moved, and the front of the knitting needle 1 is not required to be transversely moved, namely, the back of the knitting needle 1 is required to be transversely moved along the left and right (transverse) reciprocating straight line of the whole machine, so that the weft insertion of the knitting yarns between two adjacent parallel knitting chains can be realized, and therefore, the front and back swinging of the weft insertion guide bar 4-2 is redundant. The weft insertion guide bar 4-2 and the knitting guide bar 4-1 are swung together, and although the swinging of the weft insertion guide bar 4-2 does not affect the result of weft insertion, the redundant swinging of the weft insertion guide bar 4-2 not only increases the complexity of the machine structure, but also increases the movement inertia force (moment) and affects the running speed of the whole machine.
In the existing machines shown in fig. 1 and 2, a and B are respectively a groove needle bed and a needle core bed pendulum shaft, C is a guide bar pendulum shaft, and the groove needle 1-1, the needle core 1-2 and the guide bar 4 swing around the groove needle bed pendulum shaft a, the needle core bed pendulum shaft B and the guide bar pendulum shaft C, respectively.
Structurally, a plurality of looping spindle seats 5 with the same structure are arranged on the upper surface of an oil tank along the left and right directions of the machine, and a groove needle swinging shaft A and a needle core swinging shaft B are arranged in holes of the looping spindle seat 5 to realize swinging of the groove needle 1-1 and the needle core 1-2 as shown in figure 2. The guide bar pendulum shaft C is arranged in a hole of the guide bar hanger 7, the hanger 7 is arranged below the cross beam 8, two ends of the cross beam 8 are arranged on the upper surfaces of the left wall plate 6-1 and the right wall plate 6-2, and the left wall plate 6-1 and the right wall plate 6-2 are respectively arranged on two sides of the upper surface of the oil tank 9. The structure has the problems that: because the mounting holes of the groove needle pendulum shaft A, the needle core pendulum shaft B and the guide bar pendulum shaft C are not arranged on the same part, the position accuracy between the groove needle pendulum shaft A, the needle core pendulum shaft B and the guide bar pendulum shaft C is required to be ensured by means of mounting and debugging, the mounting and debugging cost is increased, the accuracy is difficult to ensure, and in addition, the mechanical structure rigidity of a looping region is poor.
The invention designs a novel structure grass-binding net warp knitting machine aiming at the problem that the weft insertion guide bar does not need to move and the mechanical structures of a needle bed swing shaft, a needle core bed swing shaft and a guide bar swing shaft are unreasonable.
