Background

The grass binding net is a fabric for binding straws, pasture and other forage grass, and is named for the use function of the grass binding net. The straw-tying net is a warp-knitted fabric, also called a knotless fishing net, and is generally produced by knitting with a warp knitting machine. The structure of the prior grass-bundling net is that a plurality of groups of parallel and same warp-knitted chains are arranged in the longitudinal direction, weft insertion is arranged in the transverse direction, and the longitudinal knitted chains are connected by the weft insertion to form a mesh fabric.

Further, when the roll length of the conventional grass net exceeds 3000m, the roll diameter becomes too large, and some of the grass binding facilities cannot be mounted, and the versatility of the grass binding facilities is poor, which is why it is difficult to make the roll length of the grass net having a narrow width longer.

The length of a roll of netting determines whether it is durable, i.e. the longer the roll length of the netting, the longer it takes, and the less frequent the change of the netting. If the length of the roll can be increased under the condition of meeting the requirements of the roll diameter and the weight of the grass binding net, the replacement frequency of the grass binding net and the time waste caused by the replacement frequency can be reduced, the labor capacity of a user is reduced, and the working efficiency is improved.

The structure, ratio, size and the like shown in the drawings of the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by people familiar with the technology, and are not used for limiting the limit conditions which can be implemented by the present invention, so that the present invention does not have the substantial significance in the technology, and any structure modification, ratio relationship change or size adjustment should still fall within the range which can be covered by the technical content disclosed by the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

Fig. 1 shows the structure of the grass baling net of the present invention, which includes a winding drum 1 and a net roll 2 located outside the winding drum 1, wherein the net roll 2 is formed by winding a net 3 on the winding drum 1 to form a cylindrical rolled grass baling net product. The winding drum 1 is generally a hollow cylindrical hard paper tube or hard plastic tube. The width of the web 3, i.e. the width of the roll 2 wound on the reel 1, is referred to as "width in weft" in this embodiment, and is indicated by "W" in fig. 1; the maximum diameter of the web roll 2, referred to as the "roll diameter", is indicated by "D" in fig. 1; the total length of the web 3 wound on the reel 1 is indicated by "L" in figure 1.

Referring to fig. 2, the net 3 comprises a plurality of warp-wise arranged braids 3-1, and two adjacent braids 3-1 are connected through wefts 3-2 to form a large-mesh net. The chaining 3-1 is formed by connecting chain links woven by looped fibers 3-1a in series, the chain links are formed by looping through a warp knitting process, and three strands of silk yarns are arranged at any position of the chaining 3-1. In the straw binding net, the warp-wise chaining 3-1 mainly plays a role in binding, and the tensile strength of the warp-wise chaining determines whether the straw binding net is easy to damage; the weft 3-2 is mainly used for connecting each chain 3-1 into a net. In the straw-tying net, at least part of the plaiting chain 3-1 further comprises a lining warp 3-1b, and the lining warp 3-1b is lined into the chain link of the plaiting chain 3-1 along the warp direction in a substantially straight manner. As a preferred embodiment, each chain 3-1 of the grass netting may have a structure with a warp 3-1 b. In some embodiments, part of the chaining 3-1 in the middle area of the straw netting can be provided with the lining warp 3-1b, and the chaining 3-1 close to the two sides is not provided with the lining warp 3-1b; it is also possible that the chaining 3-1 with the lining warp 3-1b and the chaining 3-1 without the lining warp 3-1b are alternately arranged. By adopting the warp lining technology, when the weaving chain 3-1 is pulled, the chain links and the warp lining 3-1b can jointly exert the tensile property, the strength loss caused by the looping and bending of the looped fibers 3-1a can be reduced, and the comprehensive tensile strength of the woven straw binding net is improved. Thus, when the grass net can exert the same maximum tensile strength, the denier of the loop forming fiber 3-1a and the padding warp 3-1b can be further reduced, and the unit square gram weight of the grass net can be effectively controlled, so that the gram weight of the grass net can be further reduced.

In the present example, the grammage of the knitted net 3 was controlled to 5.5g/m ² ～7.5g/m ² The unit square gram weight of the grass binding net is obviously lower than that of the prior grass binding net with the same performance, the cost of the grass binding net can be reduced, and the strength performance of the grass binding net can be fully exerted. Because the unit square gram weight of the net 3 is well reduced, the length of the grass baling net wound on the winding drum can be increased under the condition of meeting the requirements of the diameter and the weight of the grass baling net, the length L of the net 3 wound on the winding drum 1 in the embodiment is (3000-5000) ± 50m, which is beneficial to reducing the replacement frequency and the time waste of the grass baling net in the use process, lightening the labor intensity of a user and improving the working efficiency.

It should be noted that, in the case of the straw netting product, the length thereof is generally marked in the product information, such as the length 3000 ± 50m, 4000 ± 50m, 5000 ± 50m, etc. The winding length L of the grass baling net is generally measured by a meter counter in the production process, and plus or minus 50m is an allowable error range. If there is no parameter identification associated with the web, the length of the rolled web is typically obtained in two ways: one is to put the rolled straw net product on the device to be rolled again and measure the length of the straw net again; another method is to cut 1 meter of net 3 from the rolled straw netting product, weigh 1 meter of net 3 to obtain a grammage M, and divide the net weight M of the net roll 2 by 1 meter of net 3 to obtain the total length L of the net 3. The net weight M of the roll 2 can be obtained by weighing after removing the reel 1.

For the unit square gram weight of the net 3, 1 meter of the net 3 can be cut from a rolled straw netting product, the gram weight m of the 1 meter of the net 3 is weighed, and then the unit square gram weight of the net 3 is equal to the unit square gram weight of the net 3 after the unit square gram weight m is divided by the weft width W of the net 3; alternatively, when the total length L of the web 3 is known, the net weight M of the roll 2 may be divided by the widthwise width W of the web 3 and then divided by the total length of the web 3, to convert the unit square grammage of the web 3.

As a further preferred embodiment, the grammage of the web 3 can be controlled to 6g/m ² ～7g/m ² E.g. can be designed as 6g/m ² 、6.5g/m ² 、7g/m ² And the like. The length L of the web 3 wound on the roll 1 is (3500 to 4500). + -. 50m, and may be 3500. + -.50 m, 4000. + -.50 m, 4500. + -.50 m, or the like. Generally, when the length L of the net 3 is (3500 to 4500) ± 50m, the latitudinal width W of the net 3 is preferably 1.4m or less, and when the latitudinal width W of the net 3 is equal to or exceeds 1.4m, the length L of the net 3 is preferably selected to be (3000 to 3500) ± 50m, so that the weight of the whole roll of the grass net can be ensured to be moderate, and the grass net can be accepted by users more easily.

Further, when the latitudinal width W of the web 3 is less than 1.4m, the length L of the web 3 wound on the reel 1 is 4000 ± 50m, for example, when the latitudinal width W of the web 3 is 0.2m, 0.3m, 1.05m, 1.23m and 1.25m, the length L of the web 3 can be designed to be 4000 ± 50m. When the latitudinal width W of the web 3 is 1.4m or more, the length L of the web 3 wound on the winding drum 1 is 3000 ± 50m, and for example, when the latitudinal width W of the web 3 is 1.40m, 1.50m, 1.60m and 1.70m, the length L of the web 3 can be designed to be 3000 ± 50m. Generally, the net 3 is wound on the reel 1 along the warp direction, the width W of the net 3 in the weft direction is not more than 2m, the width W of the net 3 in the weft direction is generally determined by the width of the grass baling equipment, and the widest grass baling net in the market currently has a width of about 1.70 m.

Since the unit square gram weight of the net 3 is reduced, the denier of the loop forming fiber 3-1a and the back warp 3-1b can also be reduced, under the condition of not changing the material, the intuitive embodiment is that the fiber silk used for weaving can be thinner, and the winding diameter of the net roll can be smaller after the net roll is wound. In this embodiment, when the length L of the net 3 is 4000. + -.50 m, the roll diameter D of the net roll 2 is 25 to 26cm; when the length L of the net 3 is 3000 + -50 m, the roll diameter D of the net roll 2 is 21-22 cm. When the roll diameter D of the net roll 2 is 25-26 cm, the longest length of the prior grass baling net can only be 3000m; when the diameter D of the net roll 2 is 21-22 cm, the longest length of the prior grass baling net can only reach 2000m.

As shown in fig. 1 and 2, the weft 3-2 is connected between two adjacent chaining chains 3-1 in a zigzag manner, and the weft 3-2 between two adjacent chaining chains 3-1 is alternately inserted into the corresponding chain link to connect the two adjacent chaining chains 3-1. The connection points of the same chaining 3-1 and the weft 3-2 at the two sides are staggered. The distance between two adjacent plaiting chains 3-1 is preferably 2-4 cm. In the chaining 3-1 with the lining warp 3-1b, the lining warp 3-1b can be alternately arranged in each chain link of the chaining 3-1 up and down, and can also be arranged once every several chain links.

In order to enable the chaining 3-1 with the lining warp 3-1b to exert the maximum tensile performance at a lower gram weight, the denier ratio of the single filament between the two needs to be further considered, and experiments prove that the ratio of the denier of the loop-forming fiber 3-1a to the denier of the lining warp 3-1b is controlled to be 0.2-0.7 optimally, so that the chaining has stronger tensile strength under the condition of lower unit gram weight of the grass binding net, and the cost of the grass binding net can be effectively controlled. In addition, the total denier of the pillar 3-1 with the warp 3-1b is preferably controlled to 900 to 1300 denier. Weft yarns 3-2 serve primarily to connect the plurality of stringers 3-1 and not bear the warp direction load, and thus may define a denier of weft yarn 3-2 that is no greater than the denier of the looped fibers 3-1 a. Specifically, the monofilaments of the looping fiber 3-1a, the warp lining 3-1b and the weft 3-2 which are adopted can all adopt plastic flat filaments with the same thickness, the monofilament width of the looping fiber 3-1a and the weft 3-2 is 0.8 +/-0.2 mm, and the monofilament width of the warp lining 3-1b is 1.5 +/-0.2 mm. The plastic flat filament can be obtained by cutting, stretching and heating and shaping a polyethylene plastic film through a filament cutting machine.

In addition, since the lining warp 3-1b is inserted into the chain link of the chain 3-1 in a straight manner and has no connection relationship in the warp direction, the synergy effect between the two when the chain is subjected to the warp direction load needs to be considered, and if the chain 3-1 with the lining warp 3-1b is broken asynchronously when being pulled, the maximum effect of the two is difficult to be fully exerted. For this reason, the ratio of the elongation at break of the looped fibers 3-1a to the elongation at break of the backing yarns 3-1b is required to be 1.4 to 1.7 in this example. Experiments prove that the knitting chain 3-1 and the lining warp 3-1b knitted by the looped fibers 3-1a can have approximate breaking elongation by adopting the setting of the breaking elongation, so that the warp chain of the grass net can exert the maximum tensile performance. This is particularly important in the case of the chain 3-1 with the warp threads 3-1b, whereas the prior art mostly ignores the influence of the elongation at break on the warp-wise tensile strength of the grass net.

For the material itself, the breaking elongation belongs to the inherent property, and the breaking elongation of the monofilament can be changed by softening, section shape and the like. .

The utility model discloses a bundle grass net compares with current bundle grass net and has following advantage:

1. the warp lining technology is utilized to improve the tensile strength of the woven straw baling net, so that the gram weight of the straw baling net is reduced, the length of the straw baling net wound on the winding drum can be increased under the condition of meeting the requirements of the winding diameter and the weight of the straw baling net, the length of the straw baling net reaches more than 3000m, the replacement frequency and the time waste of the straw baling net in the use process are favorably reduced, the labor intensity of a user is reduced, and the working efficiency is improved.

2. By optimally designing the denier ratio and the breaking elongation of the looped fibers and the padding warp, the knitted chain has stronger tensile strength under the condition of lower unit gram weight of the grass-tying net, and the warp-wise chain of the grass-tying net can exert the maximum tensile performance.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, the technical scheme and the embodiments similar to the above technical scheme are not creatively designed without departing from the spirit of the present invention, and the present invention shall fall within the protection scope of the present invention.
