Description

Apparatus and method for weaving lawn and lawn

Technical field

The present invention relates to an apparatus and method for weaving a lawn and a lawn.

Background technique

The existing lawn tufting machines use a fixed needle to sew the lawn. Each needle has a straw line. Each knitted grass from the head to the tail is fixed in color, resulting in a whole row of needles. The lawn weaved to the end has a single color. As shown in Figure 1, the grass line inserted in the a needle is the grass line in the A-line, and the grass line of the A-line is a fixed single color, so the weaving of the grass thread is on the track. The color of the grass is the same as the color of the grass in the A-line. The color of the grass in the A-line determines the color of the grass on the grass track, resulting in a single color of the artificial grass. However, in practical applications, such as the line boundary of a football field, it needs various colors such as green, fruit green and white. The specific construction steps of the existing artificial soccer field are as follows:

1. The worker paved the entire site with a number of green lawn rolls and glued them together to make the entire sports field covered with green artificial turf;

2. The workers cut the lawn in the corresponding position according to the requirements of the drawings, and remove the green lawn of a certain width;

3. Remove the green lawn position, add it with a white lawn, and glue it with glue;

4. After the steps of cutting-removing-replenishing-bonding, the site is paved and then filled with sand and particles.

It can be seen that there should be a complete football field. Because the lawn itself has a single color and no pattern, it requires a lot of cutting, trimming and splicing work during the paving, which not only leads to a significant increase in the vulnerability rate of the entire sports field, but also has manual cutting and splicing. Large errors affect the use.

In view of this, the present invention has been specifically proposed.

And weaving together with the lawn backing when weaving the lawn.

In summary, according to the apparatus and knitting method of the woven lawn provided by the embodiment, the structure of the existing lawn tufting machine is improved, and the operation of controlling a plurality of needle bodies connected with different color bobbins is controlled by the control device, according to The color structure distribution information of the paving site is used to realize the switching of the plurality of needle bodies, so that the lawn tufting machine has the function of the woven pattern lawn, and the weaving process of the above technical scheme and the description of the weaving process, the weaving provided by the embodiment The equipment and methods of the lawn and the lawn have the following beneficial effects:

1. The degree of standardization is high. All functional line positions are calculated by computer and woven by controlled machines, reducing the intervention of human factors and making the marking line of the entire sports venue accurate.

2, the vulnerability rate is reduced, due to less seams, no splicing, resulting in higher durability of the entire sports venue.

3, can be customized, can produce complex patterns of lawns, such as maps, according to customer requirements.

4. Reduce waste of resources. For example, if the lawn of an individual area is damaged, it is only necessary to retrieve the early data and separately produce the lawn roll at that position, without all being removed.

5, personality differentiation highlights, can weave different lengths of grass on the same roll lawn, the control device as a whole coordinates the various parts of the lawn tufting machine, the degree of personalization is higher, in theory, the needle can be used for each needle The lengths are different, the knitting density of each needle is different, and the color of each needle is different.

6. The lawn woven by this technology can be easily reused for replacement. Because the turf is better integrated, it is still a separate complete turf roll when it is removed. It is easier to replace the site.

7, good elasticity, reduce the athlete's injury, the buffer layer effectively protects the athletes' individual weight-bearing joints, and the buffering effect is obvious.

8. Since the buffer layer and the lawn are integrated, the paving procedure in the actual construction is reduced, and the damage rate of the lawn is reduced.

9. Less pollution and less waste. In traditional lawn paving, some lawns need to be removed, and other colors are used. The color of the lawn is filled, and the lawn that has been removed has caused a lot of waste, while the lawn with its own pattern does not need to be trimmed and removed, and there is no waste.

10. Since there is no cutting, no culling, no repair, the amount of glue binder used in the construction process is reduced, and the environmental protection coefficient is higher.
