That is, the raw material mixing dough of the present invention forms a compounding barrel device portion 1a toward the front of the main body 1 so as to equip the compounding barrel 3 having the upper portion with an open portion 3b, but two in the compounding chamber 3a. Of the roller rollers (4) and (4a) side by side to expose the rotary shafts (4) and (4) of the two rollers to the outside of the mixing barrel (3) to expose the rotary shaft (4 ') of the driving side rollers (4'). 1a) Two dough rollers are rotated to face each other in the mixing barrel by installing them with shaft pipes (2) and (2a) fixed to the outside to secure the connecting gears (401, 402) at the ends of the two rotating shafts (4) and (4). It is also configured to form a protruding piece 301 on the outside of the mixing barrel (3) to form a shaft hole in its opening to mount the shaft rod 303 of the nut earth 302, and the screw groove in the nut support center hole 304 is formed to screw the rotary screw rod 5a to connect the lower end of the rotary screw rod with the left and right rotary devices 5 and 5b provided on the movable plate 501. It is configured to rotate the inlet (3) inlet to the inside and the outside, and in the opening portion (3b) of the compounding cylinder (3) there is a pressure plate (7) operated up and down by the hydraulic cylinder (6) installed in the main body (1) It is provided and is comprised so that the opening part of the mixing chamber 3a may be opened and closed.

Therefore, the pressure plate 7 is raised and rubber and lime are added to the compounding chamber 3a at a ratio of 5: 5, and then, a predetermined amount of plastic material is added, the compounding container 3 is established, and the pressure plate 7 is lowered. Keeping the opening of 3a) at a certain height, and then driving the driving roller (4) to rotate the kneading rollers (4) and (4a), the two kneading rollers face each other in the mixing chamber and force rubber and lime in the mixing chamber. When the rubber melts due to the frictional heat generated and mixes with the lime, it becomes a wet dough state.When complete dough, stops the rotation of the driving side roller, raises the pressure plate, and tilts the mixing barrel forward to drive the side roller. Rotating the raw material kneaded in the mixing chamber will go out of the mixing vessel.

Therefore, the mixing and kneading of raw materials can be done quickly, and mechanical work that does not depend on human power is possible, so that it is possible to achieve uniform mixing and perfect dough without effort. Is the perfect raw material to make a good reputation.

3 illustrates the plate making machine (b) of the present invention.

That is, the plate making machine used in the present invention is a pair of two rollers from the upper side of the plate making base (8) to the lower side and the rotation ratio is 10: 8 and the two plate rollers rotate to face each other (9) (9a) (10) (10a) (11) (11a) has a primary plate making unit with three or more stages installed, and the compression roller (13) (13a) (13 b) has three sets in the lower part with a rotation ratio of 10: 8: 6. (2) 14th (14a) (14b) (15) (15a) (15b) The second plate making unit is provided in three stages, and the final compression roller (16) (16a) is installed outside the lowest end. Since it is comprised so that a rubber plate of thickness can be manufactured quickly, the rubber plate 17a of desired thickness can be obtained by one pass.

This rubber plate is characterized by dense structure, smooth surface, and smoothness, and it is secured by reinforcing elasticity and firmness by injecting it into a heat hardening device.

4 illustrates a heat curing apparatus of the present invention.

That is, in the heat curing apparatus of the present invention, a heating roller 20 having a large outer diameter, which is heated by steam, is installed at the center of the heating transition body main body 18, and the heating roller 21 and the guide roller are small up and down. 22) is placed on the surface A stainless steel heating belt 23, which is an endless belt type, can be rolled up so that it can be rolled up, and a guide roller 19 is provided on the side to adjust tension, and a hydraulic cylinder 19a is placed on the shaft for adjusting the tension. The rubber plate 17a is inserted between the heating roller 20 and the stainless steel heating belt 23 to be heated and pressed in the process of forced transfer and hardened in the transfer process. On the other hand, the heating rollers 20 and 21 used in this process use a steam heating roller, the configuration of which is illustrated in FIG.

That is, in the heating roller of the present invention, the inside of the main body becomes the steam accommodating part 20 and the steam supply pipe 201 is introduced into one central shaft pipe 20a and the drain pipe 202 is inserted into the other central side pipe 20b. The inner side of the drain pipe is bent at a right angle and connected to the reservoir to forcibly remove the liquefied water that accumulates at the bottom of the heating roller 20, thereby continuously supplying high-temperature steam to the inside of the heating roller 20. The bearing device 20c is installed so as not to be disturbed by the rotation of the roller 20 so as to continuously supply steam to the rotating heating roller 20, and the stainless steel heating belt 23 is heated. It is heated by contact with the rollers 20 and 21 to impart heat and pressure necessary for the heat curing action of the rubber plate.

Therefore, the rubber plate passed between the stainless steel heating belt and the heating roller 20 can be hardened while being heated and compressed to harden into a rubber plate having a dense structure and a smooth surface. The process of falling to (24) is cooled by the film treatment agent and is coated and lifted to the outside while passing between the sponge plates (25) and (25a), the film treatment agent on the front and back surface is hardened and passed over the elastic conveyor belt (26). In the cutting roller 27 is cut to a certain standard based on the cutter 28, the finished product 17 is stacked at the outer end of the conveyor.

The present invention prepared as described above is in the process of mixing the rubber raw material with lime and adding the plastic material in the process of mixing and kneading based on the frictional heat and pressure, forming the raw material into a thin plate and heat-curing it in a flat state to cut the lamination. It is possible to manufacture rubber sheets quickly and efficiently by processing a series of manufacturing processes all together, and each process uses a mechanical device that is suitable for the purpose of the process, enabling mass production of high quality rubber plates. It is a rubber plate which is good to be used and is durable, and can obtain an advantage of being easy to use.
