Abstract

The present invention provides a continuous production method for spliced mats, which firstly carries out a continuous pre-foaming and an independent pre-foaming simultaneously. The continuous pre-foaming is configured to have a first elastic foaming sheet foamed and ripened incompletely and continuously via a first tunnel-type foaming box and output afterward. The independent pre-foaming is configured to use an independent foaming box to perform continuously and incompletely foaming and ripening and then outputting several second elastic foaming sheets. Several second elastic foaming sheets are then attached to the surface of the first elastic foaming sheet that are moving. Finally, the laminated first and second elastic foaming sheets are continuously fed into a second tunnel-type foaming box for foaming and ripening completely, so as to obtain a spliced mat with two-layered elastic materials.

Description

Continuous production method of splicing mat

The present invention is related to children's splicing floor mats, and more specifically refers to a continuous method for splicing mats.

According to, there are two methods for making spliced floor mats. One is to continuously input sheet-shaped elastic foaming materials into a tunnel-type foaming box and then output them after foaming, and then cut them into spliced floor mats. The second is to repeat them. The action of feeding the elastic foam material into a single or multiple molds of an independent foam box (such as a flat foam machine) after foaming is completed. The production efficiency of continuous foaming using tunnel-type foaming box is high, but it will produce cutting waste, while independent foaming box can be directly foamed to complete the splicing floor mat of the predetermined shape without cutting waste, but it is non-continuous The production efficiency of the foaming process is not as good as that of the continuous foaming process using the tunnel foam box.

Secondly, although most of the conventional spliced floor mats are made of a single material (such as EVA, etc.) foamed, in order to have both softness and anti-slip properties, some spliced floor mats are made of foam materials of different materials. However, the double-layer (including above) splicing floor mats made of different materials of foam materials are prone to problems of poor service life and easy damage due to the degree of expansion, hardness or density of different layers of heterogeneous materials. .

Please refer to Fig. 1 and Fig. 2, the continuous method 100 of splicing mat 10 according to a preferred embodiment of the present invention, the first step is dual-mode synchronous pre-foaming 110: a continuous pre-foaming 111 is carried out simultaneously The step and the step of an independent pre-foaming 112, the step of the continuous pre-foaming 111 is to output a first elastic foam sheet 12 continuously through a first tunnel-type foaming box 1 after incomplete foaming and maturation The step of the independent pre-foaming 112 is to continuously input the sheet-shaped elastic foaming material into the mold 3 of the independent foaming box 2, and output the connected, unbroken, incompletely foamed and matured plural second foaming materials with a predetermined shape. The elastic foam sheet 14 (the second elastic foam sheet 14 is connected, and the unbroken part is not placed in the mold and not foamed). The first tunnel-type foaming box 1 is a vulcanized foaming box installed on a conveyor belt in the conventional continuous foaming process of rubber materials. The flat-plate foaming vulcanization equipment for foaming one or several foam parts, the detailed structure of the first tunnel-type foaming box 1 and the independent foaming box 2 will not be described here. The first elastic foam sheet 12 and each second elastic foam sheet 14 are made of different elastic foam materials. The first elastic foam sheet 12 is placed on the conveyor belt and adopts PV (PVC) elastic foam material. But not limited, the degree of pre-foaming through the first tunnel-type foaming box 1 is 30-50%, lower than the foaming degree of each of the second elastic foam sheets 14 passing through the independent foaming box 2 60-80% , each of the second elastic foam sheets 14 is made of PU elastic foam material, but not limited thereto.

The second step of the present invention is pasting 120: it is first to apply an adhesive material 16 on the surface of the first elastic foam sheet 12, and to be glued, and then each of the second elastic foam sheets 14 is applied by a rolling machine 4 Sequentially stick to the first elastic that continues to move The surface of the foam sheet 12.

As for the first elastic foam sheet 12 and the second elastic foam sheet 14 The type of elastic foam material to be used depends on whether the first tunnel-type foam box 1 or the independent foam box 2 is suitable for pre-foaming, which is only a material choice.

In addition, the first elastic foam sheet 12 and the second elastic foam sheet 14 can also use polar (hydrophilic) and non-polar (lipophilic) elastic foam materials (polar waste materials such as those containing nylon or PET) respectively. Polymers, non-polar waste materials such as polyolefin polymers, etc.) (at this time, the first elastic foam sheet 12 and the second elastic foam sheet 14 are heterogeneous materials), and the surface of the first elastic foam sheet 12 The coated adhesive material 16 can be composed of the elastic foam materials of the first elastic foam sheet 12 and the second elastic foam sheet 14 mixed. Thereby, the first elastic foam sheet 12 and the second elastic foam sheet 14 can be bonded through the adhesive material 16 including the material characteristics of the first elastic foam sheet 12 and the second elastic foam sheet 14, which can further improve The bonding strength of the first elastic foam sheet 12 and the second elastic foam sheet 14 after foaming.
