Description

manufacturing process of foaming pad with multiple lines

Technical Field

the present invention relates to a manufacturing technique of foaming material, and more particularly to a manufacturing method of a continuous foaming pad with multiple textures.

Background

Rubber is widely used in daily life due to its characteristics of high elasticity, good recovery, fatigue resistance, slip resistance, wear resistance, etc., and is one of the most common and important raw materials in industry.

The general manufacturing method of rubber foam can be roughly classified into two general types, i.e. a continuous extrusion method and a molding method, wherein the continuous extrusion method comprises pressing the mixed rubber raw material into a rubber sheet by an extruder, placing the rubber sheet on a conveyor belt of a conveyor, continuously feeding the rubber sheet into a vulcanization foaming box, vulcanizing and foaming the rubber sheet into rubber foam, and the hot-pressing method comprises heating and pressing the rubber raw material by a mold. The former patents related to the production of rubber foam are shown in Taiwan patent application No. 77101565, "manufacturing method of artificial rubber foamed foot pad", No. 82102866 "manufacturing method of rubber or artificial rubber foam", No. 88100802 "antistatic rubber foam and its manufacturing method", No. 91132350 "manufacturing method of continuous rolled elastic cloth laminated rubber material", No. 92100377 "continuous molding method of rubber-bonded metal plate material", No. 89106811 "carpet covering article with cushion having at least one integrated rubber protrusion", and No. 90115918 "manufacturing method of normal pressure continuous rolled rubber foamed embossing". Since the continuous extrusion method has a faster production speed than the molding method and a lower energy consumption, it is more economical and widely used in the industry.

from the above, it can be seen that, due to the requirement of product diversity, the rubber foamed products with simple and non-pattern finish gradually do not meet the market requirement, and with the increasing requirement of people for product texture, the foamed products obtained by the existing technology cannot be used all the time, so how to continuously develop the foamed products with different physical properties for improving the appearance and the application, which are different from the existing technology, is the object and the direction of the research and development breakthrough in the related industry.

the present inventors have considered this, and have made careful observation and study based on many years of experience in this field, and have applied this with the help of theory, to provide a rational and effective invention.

wherein the plurality of shaping structures formed on the surface of the shaping sheet 13 are porous structures of meshes, holes and gaps; furthermore, the surface of the shaping sheet 13 is more concave-convex to form a porous structure; however, the porous structure is of various shapes;

more specifically, the shaping sheet 13 described herein is any of various types of release fabric, shaping paper, shaping web, or continuous sheet with shaping function, and is preferably continuously supplied in a roll form; furthermore, in step S3, the stretching means applying an external force to the shaping sheet 13 to make it substantially flat and able to carry and transport a certain weight without deformation;

step S4: rolling and superposing: the flexible sheet 11 carries the elastic sheet body 12 and the shaping sheet 13 to move towards a first processing area 3, so that the flexible sheet 11, the elastic sheet body 12 and the shaping sheet 13 pass through the first processing area 3, and the flexible sheet 11, the elastic sheet body 12 and the shaping sheet 13 are rolled in the first processing area 3 and are overlapped with each other to form a sheet shape;

furthermore, the two pressing wheels 42 of the second processing area 4 are arranged at a predetermined distance, and the two pressing wheels 42 are driven by power to rotate in opposite directions and have a predetermined temperature H;

to be more specific, in step S5, the two ovens 41 have predetermined temperatures H, when the flexible sheet 11 carrying the elastic sheet 12 and the shaping sheet 13 moves to a second processing area 4 between the two ovens 41, wherein the predetermined temperature H of the oven 41 above the shaping sheet 13 is lower than the predetermined temperature H of the oven 41 below the flexible sheet 11, so that the flexible sheet 11 carrying the elastic sheet 12 and the shaping sheet 13 passes through the two ovens 41 and is affected by different temperatures, which causes the softening of the upper and lower end surfaces of the elastic sheet 12 to be different, and then the two pressing wheels 42 are pressed to control the combination; since the shaping sheet 13 is separated from the surface of the elastic sheet 12 at the end of the whole process, the flexible sheet 11 is not separated from the surface of the elastic sheet 12 at the end of the whole process; therefore, in step S5, the temperatures H of the two ovens 41 need to be adjusted and controlled, so that the predetermined temperature H of the oven 41 above the shaping sheet 13 is lower than the predetermined temperature H of the oven 41 below the flexible sheet 11, and the two pressing wheels 42 are used for pressing and controlling, so that the shaping sheet 13 is bonded to the surface of the elastic sheet 12 in a temporary bonding state; the flexible sheet 11 is attached to the surface of the elastic sheet 12 to form a permanent bonding state; so that the shaping sheet 13 can be easily separated from the surface of the elastic sheet 12 in the final process;
