Description

Foam pad system with multiple lines

The present invention relates to the process technology of the foam, and more specifically to a process method of continuous and multi-grain foaming pad.

According to its high elasticity, good recovery, fatigue resistance, slip resistance and wear resistance, rubber is widely used in daily life and has become one of the most common and important raw materials in the industry.

Generally, the conventional rubber foam can be divided into two types: a continuous extrusion method and a molding method. The continuous extrusion method presses the rubber raw material after the mixing into a rubber sheet by using an extruder, and places the rubber sheet. On the conveyor belt of the conveying machine, the sulfur is added to the vulcanization foaming box to form a rubber foam, and the hot pressing method uses a mold to heat and press the rubber material. Patent application for the production method of rubber foam, such as Invention No. 77101565 "Method for making artificial rubber foaming mat", No. 82102866 "Improved method for rubber or artificial rubber foam", No. 88100802 "Resistance" "Electrostatic rubber foam and its preparation method", No. 91132350 "Manufacturing method of a continuous roll elastic cloth bonding rubber material", No. 92100377 "Continuous molding method of rubber bonded metal sheet", No. 89180811 "containing at least one Buffered carpeted floor coverings with integrated rubber protrusions and No. 90115918 "Normal pressure continuous roll rubber foam embossing method" The case shown. Since the continuous extrusion method is faster than the molding method and the energy consumption is low, it is more economical and widely used in the industry.

The elastic sheet 12 and the shaped sheet 13 are rolled to overlap each other in a sheet form; further, the first treatment zone 3 of the present invention mentioned in step S4 has a roller pressure. The sheet machine 30 uses the roller tablet press 30 to roll the flexible sheet 11, the elastic sheet 12 and the shaped sheet 13 to be superposed on each other in a sheet form; wherein the roller The tablet press 30 has two pressing wheels 31 which are disposed at a predetermined distance apart, and the two pressing wheels 31 are driven by the power in a state opposite to the rotation direction and have a predetermined temperature H; and the two pressing wheels 31 are interposed therebetween. The distance position can be adjusted to adjust the gap to an appropriate gap to determine the flexible sheet 11, the elastic sheet 12 and the plastic The sheet 13 is rolled to be superposed on each other in a sheet-like shape; step S5: thermocompression bonding: after being rolled and laminated, the elastic sheet 11 is carried by the flexible sheet 11 and the shaped sheet The material 13 is moved toward a second processing zone 4, so that the flexible sheet 11, the elastic sheet 12 and the shaped sheet 13 pass through the second processing zone 4, and the temperature is utilized in the second processing zone 4. H controls the degree of softening of the elastic sheet 12 as a whole, thereby controlling the degree of adhesion (permanent bonding) of the flexible sheet 11 to the surface of the elastic sheet 12; and bonding the elastic sheet 13 to the elastic sheet 13 The surface of the sheet 12 has a degree of adhesion (temporary bonding); wherein, in the step S5, the second processing area 4 has two types; the second processing area 4 for the two types is further described as follows: First, the second processing zone 4 is selected from the two ovens 41, and the flexible sheet 11 after rolling and lamination, the elastic sheet 12 and the shaping sheet 13 are disposed between the two ovens 41. Heating at a high temperature to control the overall degree of softening; and two pressurizing wheels 42 that are driven by power to be in a rotating state; The sheet 11 , the elastic sheet body 12 and the shaping sheet 13 are pressurized between the two pressing wheels 42 to control the degree of bonding; in addition, the second processing zone 4 two pressing wheel 42 The two pressurizing wheels 42 are driven by the power to rotate in opposite directions and have a predetermined temperature H. Further, in the step S5, the second oven 41 has a predetermined temperature H. When the flexible sheet 11 carries the elastic sheet 12 and the shaped sheet 13 is moved between the second processing zone 4 and the second oven 41, the oven 41 above the shaping sheet 13 The predetermined temperature H is lower than the predetermined temperature H of the oven 41 below the flexible sheet 11, whereby the flexible sheet 11 carries the elastic sheet 12 and the shaped sheet 13 passes therethrough. After the two ovens 41 are affected by different temperatures, the degree of softening of the upper and lower end faces of the elastic sheet body 12 is different, and the degree of bonding is controlled by the pressure between the two pressing wheels 42; The sheet 13 is finally separated from the surface of the elastic sheet 12 in the overall process, and the flexible sheet 11 is finished. The process does not need to be separated from the surface of the elastic sheet 12 at the end; therefore, the temperature H of the two ovens 41 must be adjusted and controlled in step S5, so that the oven 41 located above the shaped sheet 13 The predetermined temperature H is lower than the predetermined temperature H of the oven 41 below the flexible sheet 11, and is controlled by the pressure between the two pressure rollers 42 so that the shaped sheet 13 is bonded to The surface of the elastic sheet 12 is temporarily bonded; and the flexible sheet 11 is adhered to the surface of the elastic sheet 12 to exhibit a permanent bonding state; thereby, the shaped sheet 13 can be easily separated in the final process. The elastic sheet body 12 has its surface; the second processing zone 4 is selected from a heating roller 43 which is driven by the power to be in a rotating state; and a resisting member 44 which is in a semi-arc shape as a whole.

When the channel 45 is transported, the predetermined temperature H of the oven 46 above the shaped sheet 13 is lower than the predetermined temperature H of the heating roller 43 below the flexible sheet 11, thereby making the deflection The sheet 11 carries the elastic sheet 12 and the shaped sheet 13 passes through the transport channel 45. The influence of the different temperature H of the heating roller 43 and the oven 46 causes the elastic sheet body 12 to have different degrees of softening on the upper and lower end faces thereof, and then the pressure is controlled by the pressing member 44 to control the degree of bonding; The sheet 13 is finally separated from the surface of the elastic sheet 12 in the overall process, and the flexible sheet 11 does not need to be separated from the surface of the elastic sheet 12 in the overall process; therefore, it must be in step S5. The temperature H of the heating roller 43 and the oven 46 needs to be adjusted and controlled, so that the oven 46 located above the shaping sheet 13 has a predetermined temperature H lower than that below the flexible sheet 11. Heating the roller 43 at a predetermined temperature H, and controlling the degree of pressurization between the resisting members 44, so that the shaped sheet 13 is bonded to the surface of the elastic sheet body 12 to exhibit a temporary bonding state; and the flexible sheet material 11 is adhered to the surface of the elastic sheet 12 to exhibit a permanent bonding state; thereby, the shaped sheet 13 can be easily separated from the surface of the elastic sheet 12 in the final process; Step S6: Surface grain forming treatment: After the thermocompression bonding, the flexibility The sheet 11 carries the elastic sheet 12 and the shaped sheet 13 to move to a third processing zone 5, so that the flexible sheet 11, the elastic sheet 12 and the shaped sheet 13 pass the third treatment.
