Abstract

Synthetic resin in a complex vibrating apparatus(6) extrudes from the nozzle of a die(8) form strands. This strand drops into a roller tank(6), which is attached to (6). The clearence of the driving rollers(1,2) is adjustable. The first roller(1) contacts with water surface. The height of the second roller is greater than the first and it can be adjusted. the strand passes through the rollers(3,4) which draw the cooled strand through the water. The thickness, velocity, and density of the strand can be changed by adjusting the driving rollers(1,2). After passing the rollers, the strand is adheared to a floor mat.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a floor mat and a device thereof, and more particularly, to a method of manufacturing a flow mat in which a multi-layered flexible synthetic strand is formed on a surface of a sheet substrate.

Conventionally, there have been many kinds of such floor mats, and many of them have formed protrusions on sheet substrates and mats such as artificial turf. However, these mats are defective in elasticity, generate heat during friction, or slip due to moisture or moisture when laid on a porch in rainy weather.

The present invention improves this coupling to form strands on coils on the sheet substrate of the mat.

The present inventors have diligently studied and studied to manufacture such a mat, and found that the part for producing the strand formed on the sheet substrate was kept secret, and the other part could be easily made by known technology.

An embodiment of the present invention will be described below with reference to the drawings.

1 is a perspective view of a floor mat made in accordance with the present invention.

2 shows a schematic view of the process of the invention placed on top, bottom, left and right continuous compound oscillators 6, in which the extruder a has a die 8 with a hopper and a nozzle.

Put the resin used for the strand into the hopper. In this case, examples of the resin used include soft synthetic resins such as polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polyethylene, polypropylene, polyamide, and the like.

The synthetic resin extruded while vibrating up and down, left and right, and back and forth by the continuous composite vibrator 6 forms a strand through the die 8 provided with a plurality of nozzles, which falls on the roller forming roller tank b. do. The tank (b) is a device for forming and entangled strands. The rollers (1) and the rollers (2) can be adjusted at regular intervals, such as 5 to 50 mm, depending on the thickness and swelling properties of the strands required. (b) can be vibrated up and down, left and right, back and forth or by vibrating, vibrating or compound vibration. In addition, the roller (2) may be located higher than or equal to the roller (1), but this allows to be arbitrarily adjusted according to the water level (水位). Therefore, the roller 2 is attached to the lever (not shown in figure) which can adjust its position.

이 로울러(1)보다 높게 위치시키는 것이다. 또한 노즐이 부착된 다이 단부와 로울러(1)의 상단부 거리(H)는 스트랜드의 물성을 정하는 인자로 작용한다. 즉 이거리(H)의 차에 따라 스트랜드의 굵기, 부풀음상태, 스트랜드사이의 밀도 등이 변화하나, 일반적으로 10~30mm내로 조정함이 바람직하다.However, the difference between the position of the roller 1 and the roller 2 varies depending on the strand to be obtained, but preferably, the position of the roller 2 and the roller 1 is higher than the position of the roller 2 and the roller 1, more preferably. (2) of radius

It is located higher than this roller (1). In addition, the distance H between the die end to which the nozzle is attached and the upper end portion of the roller 1 serves as a factor for determining the physical properties of the strand. That is, the thickness of the strands, the swelling state, the density between the strands and the like changes depending on the difference in the distance (H), but in general it is preferable to adjust within 10 ~ 30mm.

The strands from the nozzles of the die fall to the position of the rollers (2) on the water surface, the rollers (1) which are in close contact with the water surface. The thickness and swelling are different and the strands passing through the rollers (1) and (2) are entangled to pass through the rollers (3) and (4). The distance between the rollers (1) and (2) is adjusted to a constant interval, preferably 5 to 50 mm, unlike rollers used in the manufacture of ordinary sheets. Of course, the speeds of the rollers 1 and 2 are adjusted according to the desired strands.

The entangled strands passing through the rollers 3 and 4 pass through the rollers 5 and then pass through the tank d in which the sol is impregnated to allow the strands to mate with each other. This is because the strands passing through the tank (b) are not completely fused to each other, so that they are secondarily sol-coated and bonded. The interlaced strand that has passed through the tank d is wound around the winding machine g via the oven e and the side cutting machine f. The strand thus produced differs in thickness depending on the speed of the roller and the type of resin, but is preferably adjusted to a thickness of 0.2 to 5 mm in diameter. The strand thus made can then be attached to the sheet substrate and used to produce the floor mat.

On the other hand, in order to make this a continuous process, the strand passed through the tank (b) and passed through the conveyor (c) above is passed through a sheet substrate, preferably a roller (h) on which an unfoamed sheet substrate is wound, and then a foaming oven. (i), passing through the drying oven (j), in which the strand passing through the dry oven is attached by attaching a device capable of applying a separate sol-like adhesive. The passed mat is wound around the winding machine 1 via the side cutting machine k. The sheet substrate is preferably a foam sheet, and these materials have a softening point homogeneous to or close to that of the strand, for example, polyvinyl chloride, a polyurethane foam sheet having a low melting point, and an appropriate amount of poly in polyurethane. Polyurethane foam sheet blended with foamed vinyl chloride, foamed foam sheet formed by polymerizing polyurethane foam and polyvinyl chloride foam sheet, and the like may be cited. It can be used and its thickness can be selected for convenience, but it is preferably about 2 ~ 50mm.

As described above, according to the present invention, the desired floor mat can be manufactured with extremely high efficiency.

In addition, the strand forming tank (b), which is the main apparatus of the present invention, has the advantage that its parts, that is, the rollers and the tank, can be changed according to the purpose, and the desired strand can be obtained by fixing or vibrating the entire tank.
