Description

Apparatus for the application of latex to artificial turf pile {AN APPARATUS FOR APPILCAION OF LATEX TO ARTIFICIAL TURF PILE}

The present invention not only makes it easy to adjust the amount of latex coating, but also improves the structure of the knife to enable more effective application with a smaller amount of latex, thereby making it easier to control the amount of latex and reducing the amount of latex input. The present invention relates to an apparatus and a method for applying latex to an artificial turf pile, which can produce a tufted artificial turf having a pull strength of not less than that of the turf.

As a method of manufacturing artificial turf, a single rashel method, a double rashel method, a tufting method and the like have been used.

In the case of the double raschel method, pile yarns are entangled and woven together on two grounds of artificial turf at the same time, so that the center sliting process of cutting the center portion of the artificial turf pile is added with a knife, thereby increasing the complexity of the process. In order to establish the cutting conditions of the center slitting process, a lot of product loss occurs, and the center slitting process frequently occurs while the artificial grass pile entangled on two grounds is not upright. There was a problem that the pile height of the initial part and the end part of the product after the casting process is not uniform. In addition, the single-lasel method can increase the pulling strength and pile height of the pile without a separate center slitting process, but has a disadvantage of low artificial grass production efficiency. On the other hand, in the case of the tufting method used in the manufacture of most artificial turf, there was a problem that the pull-out strength (tear strength) of the artificial turf pile falls and the pile surface is not uniform.

The artificial turf produced by the tufting method has superior productivity compared to the artificial turf produced by the Raschel method or other methods, but since the file is easily detached, the latex (latex) and the application amount of the artificial turf file fixed to the bubble paper Is one of the important points in producing artificial turf.

Latex coating of artificial turf is roughly divided into a pile down method and a pile up method. The pile down method is a method in which the latex is applied to the upper end of the pile while the pile surface of the fabric is positioned below, and then latex is applied using a roll or the like. In this method, the coating of latex can be performed sufficiently and uniformly, but latex consumption is high in comparison with the pile up method, and in some cases, latex flows down to the pile surface, thereby damaging the product quality. On the other hand, the pile up method is to install a plate containing latex at the bottom of the pile while the pile surface of the fabric is upward, install a roll that can be constantly buried on the pile surface, apply latex, and then use a knife or the like. By adjusting the coating amount. Compared to the pile-down method, this method has a small amount of latex coating, but a relatively uncoated portion easily occurs, and it is not easy to control the amount of latex coating.

Accordingly, the inventors of the present invention have made an effort to control the amount of latex and to reduce the amount of latex by adjusting the structure of the knife so that the amount of latex can be easily controlled and the amount of latex can be more effectively applied. In addition, the present invention has devised an apparatus and method for the application of latex to artificial turf piles that can produce tufted artificial turf having a pull strength of not less than that of existing tufted artificial turf.

The present invention not only facilitates the adjustment of latex coating amount and reduces the amount of latex input, but also can produce a tufted artificial turf having a pull strength of not less than that of conventional tufted artificial turf. It is an object to provide an apparatus and method for the application of latex.

The present invention is a device for applying the latex to the artificial turf pile in a pile up method, the latex holding plate 10 and the latex supply device 20 connected to the latex holding plate 10 on the bottom of the artificial grass pile ), A roll 30 to apply the latex to the artificial turf pile, and a knife 40 to adjust the amount of latex application, the knife 40 is the end portion of the artificial turf file is passed through the irregularities configured at regular intervals Provided is an apparatus which can concentrate latex application only.

The knife 40 has a different unevenness interval for each direction, it is preferable that the angle can be adjusted, because only the portion passing the artificial turf pile can concentrate the latex application, it is possible to properly adjust the amount of latex application.

 In addition, the knife 40 has a different unevenness interval for each direction, it is preferable that the angle can be adjusted, because it can correspond appropriately according to the needle spacing of the tufting base, and thus can appropriately adjust the amount of latex coating to be.

Apparatus for applying the latex to the artificial turf pile in a pile up method of the present invention is the portion of the knife 40, the artificial turf pile directly close to the left and right bent around the center of the latex is not required May further comprise a latex recovery means for returning back to the latex retaining plate 10 after it has fallen below the knife and collected at the knife central portion.

The latex recovery means flows the latex removed from the artificial turf pile in a predetermined direction in front of the knife 40 to return to the latex holding plate 10.

Apparatus for applying the latex to the artificial turf pile in the pile up method of the present invention is a pile of artificial turf woven in a tufted form of gauge, such as 5/32, 3/8 or 1/8 It can be used to increase the latex coating efficiency by applying a latex to the.

The process of applying the latex to the artificial turf pile will vary depending on the expected form, but generally consists of three steps: the introduction of the tufted fabric into the coating machine; Applying a latex to the tufted fabric using a roll with latex embedded therein; And controlling the amount of latex applied by using a knife on the tufted fabric having latex embedded therein.

The apparatus for applying the latex to the artificial turf pile by the pile up method of the present invention also goes through the three-step process as described above, but as described above, the latex application amount is controlled by providing an improved knife and latex recovery means. It can facilitate and reduce the amount of latex input.

According to the present invention, it is easy to control the amount of latex coating, but by improving the structure of the knife to enable more effective application with a smaller amount of latex, it is possible to facilitate the adjustment of the amount of latex and to reduce the amount of latex input In addition, it is possible to produce a tufted artificial turf having a pull strength of not less than that of existing tufted artificial turf.
