Description

Grass-wrapping net with weft lengthening design and manufacturing process thereof

Technical Field

The invention relates to a grass wrapping net with a weft lengthening design and a manufacturing process thereof.

Background

The grass wrapping net is mainly used for bundling the turf and is mainly suitable for the developed national farm at present, and the grass wrapping net is mainly operated by placing the turf on the grass wrapping net and then wrapping the turf into rolls. The existing grass-wrapping net structure (shown in fig. 1) comprises warp threads 101 and weft threads 102, wherein the intervals between the warp threads 101 are fixed during manufacturing, and the weft threads 102 penetrate between the warp threads 101 and form triangular meshes 103 at the intervals of the warp threads, as shown in fig. 1, the triangle is an isosceles triangle. During the use of the grass covering net, the warp threads 101 can be pulled and elongated, so that the distance between the bottom edges of the meshes 103 of the isosceles triangle is elongated, and the distance between the bottom edges of the meshes 103 of the isosceles triangle is elongated, so that the height of the bottom edges of the isosceles triangle is correspondingly reduced, the vertex of the isosceles triangle is close to the bottom edge, and the distance between the adjacent warp threads is reduced, so that the size of the original grass covering net in the whole width direction is reduced, and the grass covering effect is not ideal. In order to ensure that the grass wrapping net can wrap the two sides of the turf completely, the grass wrapping net needs to be designed in a wider width for the turf with the same width, and the material waste cost is increased.

Disclosure of Invention

In order to solve the above problems, the present invention is to provide a grass-covering net with weft lengthening design, which has a width that remains unchanged during use to achieve a more desirable grass-covering effect.

In order to achieve the purpose, the invention provides the following technical scheme: a grass-wrapping net with weft lengthening design is formed by weaving warp and weft, and is characterized in that: the weft is inserted into the warp, the weft forms isosceles triangle meshes in the intervals of the warp, the length of the waist of each isosceles triangle mesh is L, the distance between every two warps is d, and the relation formula of the L and the d is as follows:

. The warp threads located at the extreme sides have higher elasticity than the other warp threads.

According to the grass-wrapping net with the weft lengthening design, the isosceles triangle meshes formed by the weft are longer than the original isosceles triangle meshes in length, and therefore the isosceles triangle meshes are in a nonlinear bending state, in this way, when the grass-wrapping net is used, although the base distance of the isosceles triangle meshes is lengthened due to the fact that the warp is pulled and lengthened, the base length of the isosceles triangle meshes is in the nonlinear bending state, even if the waist is slowly stretched, the base is not completely straightened, the height of the base of the isosceles triangle cannot be changed, namely, the vertex of the isosceles triangle cannot be close to the base but stays in the original position, the distance between the adjacent warp cannot be changed, the size of the grass-wrapping net in the whole width direction cannot be reduced, the grass-wrapping net is exactly matched with complete wrapping of turf with the same width, a more ideal grass-wrapping effect is achieved, and meanwhile, the material is saved for the grass-wrapping net, and the cost is reduced. In addition, the warps positioned at the two most sides have higher elasticity than other warps, so after the turf is packed in a rolled manner, the warps at the two most sides of the grass-wrapping net can tightly wrap the two ends of the turf, and an ideal grass-wrapping effect is further achieved.

Meanwhile, the invention provides a manufacturing process of the grass wrapping net with the weft lengthening design, which is characterized in that: on a knitting machine, warps and wefts are respectively conveyed, weft knitting needles which move left and right are arranged between the warps, the wefts penetrate through holes at the ends of the weft knitting needles, the wefts are inserted into two adjacent warps to form isosceles triangle meshes when the weft knitting needles move left and right, and baffles are arranged on the left and right moving paths of the weft knitting needles and enable the weft knitting needles to deviate from the original paths and move for a longer distance.

The upper end face of the baffle is an arc surface, and the arc surface can be adjusted up and down.

The baffle include the base, the base on be equipped with the lift groove the lift inslot be equipped with the elevator, the elevator up end do the arc surface the elevator bottom is connected with the screw rod, the screw rod with the base spiro union the screw rod is kept away from the tip of elevator is installed the gear, corresponds the gear is equipped with the lead screw, this lead screw with the gear meshes mutually, the lead screw by motor drive.

Through the design, in the manufacturing process of the grass covering net, when the weft is in a walking position, the baffle is added, so that the weft knitting needle can deviate from the original path to walk for a longer distance, the length of the hooked weft is increased, and finally the waist length of the isosceles triangle mesh is increased to form allowance, so that the width of the manufactured grass covering net can be kept unchanged in the using process to achieve a more ideal grass covering effect; and the arc surface on the baffle can be adjusted from top to bottom, so that the allowance of the weft can be adjusted and controlled according to actual conditions.

The invention is further described with reference to the following figures and detailed description.

Detailed Description

The present invention will now be described specifically by way of examples.

As shown in figure 2, the invention discloses a grass-wrapping net with weft lengthening design, which is formed by weaving warp 1 and weft 2, wherein the weft 2 is inserted into the warp 1, the weft 2 forms isosceles triangle meshes 3 in the intervals of the warp 1, the length of the waist of the isosceles triangle meshes 3 is L, the distance between the warp 1 is d, and the relation formula of the L and the d is as follows:
