Description

Embossing rollers and its manufacturing method {the method and a roller to manufacture seats}

The present invention relates to an embossing roller for embossing the surface of a synthetic sheet or wallpaper, in particular, by adopting a method of filling by using a centrifugal force when filling the molten cast iron during the production of the roller, more robust, high temperature Also relates to a durable embossing roller and its manufacturing method.

In general, embossing is applied to the surface of synthetic resin sheets, wallpaper, and leather, and an embossing method is employed in which the embossing of the roller is transferred to the surface of the sheet or wallpaper by passing an embossed roller on the surface thereof.

At this time, in order to make the embossing work more efficient, it must be pressed under moderate pressure with a hot roller.

Therefore, the embossing roller and its manufacturing method for this work has been developed a lot.

So here's a look at the developed process, looking at the problems in detail.

First, in manufacturing a roller used for embossing on the surface of a conventional synthetic resin sheet, wallpaper or leather, a method of corrosion by transfer has been used.

That is, in order to transfer the concave-convex pattern on the surface of the synthetic resin sheet or the like, the silicone is coated and cured, and then cured to separate the sample and the transfer plate made of silicon.

The surface of the separated transfer plate is nickel plated again, a transfer liquid is applied to the nickel plated transfer plate surface, and the transfer pattern is transferred to the roller.

At this time, the transfer method to the roller is a method of corroding the surface of the roller.

This conventional corrosion method is difficult to manufacture, the transfer surface is not smooth to transfer by the corrosion, the pattern is not clear compared to the pattern of the sample.

Therefore, it was almost impossible to express delicate patterns.

Secondly, in order to solve this problem, the conventional patent (patent registration No. 279327) embosses by plating nickel on the inner circumferential surface through a silicon plate manufacturing process for forming an uneven pattern and a tube manufacturing process for forming the silicon plate in a cylindrical shape. It adopts a method of transferring.

In other words, the nickel plating electroplating process is a silver diameter treatment on the inner embossed surface of the silicon tube, and then repeated this process to remove a certain thickness of nickel plating (nickel pipe), to remove the external silicon tube.

Also, the shaft of the roller is inserted into the inner center of the nickel pipe, and the inside of the nickel pipe is filled with a filler mixed with a ceramic adhesive, a water reducing agent, a fluidizing agent, and a retarder to complete the embossing roller.

However, even when the embossing roller manufactured in this way, there are many problems when embossing at high temperature and high pressure.

In other words, filling the oil in the center of the shaft to maintain the high temperature, pressurized to high pressure, when the embossing work on the synthetic resin sheet, the ceramic filling layer formed in the middle layer of the embossing roller is broken due to the high temperature, high pressure durability is broken The embossing was not efficient because of poor thermal conductivity.

Third, a method developed to solve such a problem is a "method of manufacturing an embossed roller" that has been recently filed and published (Patent Publication No. 2001-16311).

However, this method also solves the above-described problem to some extent, but the problem is described in detail with reference to FIGS. 9 and 10.

 The present invention starts with a transfer plate manufacturing process 100 for manufacturing a transfer plate 110 having a concave-convex pattern is formed from a sample disc such as fabric, leather or embossed material, the transfer plate obtained through the transfer plate manufacturing process 100 The plate 110 is rolled up to form a tubular body and coupled to the rolled roller 210 to undergo a transfer tube manufacturing process 200 for manufacturing the transfer tube 220.

In addition, the degreasing step 300 for removing foreign substances such as oil squeezed in the transfer tube 220 and the plating tube 510 in the transfer tube 220 from which impurities are removed through the degreasing step 300. In order to facilitate the peeling in the manufacturing process using a peeling agent cloth tool 410 is subjected to a peeling treatment step 400 of coating the peeling agent according to the peeling treatment means by the peeling treatment.

In addition, a plating tube manufacturing process 500 for manufacturing a plated tube by coating a synthetic resin on the transfer tube peeled through the peeling treatment process, and by rotating the cover to cover the plating tube on the inner surface of the plating cube. Conductive impregnation process (600) for conducting conductive spray by spraying a silver liquid consisting of silver nitrate mixed with ammonia water and a reducing agent consisting of hydridine and sodium hydroxide with silver liquid application sphere for imparting conductivity, and plating for conductive treatment through the conductive impurity process A plated nickel tube manufacturing process 700 for immersing a tube in a plating solution to form a plated nickel tube, inserting a shaft member into the plated nickel tube obtained through the plated nickel tube manufacturing process, and between the shaft member and the plated nickel tube. The embossing roller is produced by going through the filler filling process 800 for filling the metal filler in the space.

However, as mentioned earlier, this approach is tricky and expensive.

In addition, a lot of bubbles are generated inside the filler filling step of pouring the molten metal as it is, and its robustness is questioned.

In addition, the silver liquid used during the conductive imparting process is severely corroded, and it is corroded black even after being exposed to air for a certain period of time, and its shape change is severe.

Therefore, it is expected that the surface of the manufactured embossed roller will not be finely smooth either.

In addition, in the case of the electroconductive imparting process of this method, the silver liquid is drawn out in the direction of the arrow shown in FIG. 10, and the mold is immersed in the plating liquid, so that the mold may be eroded, and there are a lot of defects because the temperature change is unbalanced.

In addition, due to the improper drug circulation due to the flow of the silver liquid rubbing to the appearance of the titanium basket, bubbles are likely to occur.

These bubbles interfere with the plating process and eventually do not produce a smooth embossed surface.

The present invention, which solves the above-mentioned problems, relates to an embossing roller for embossing a surface of a synthetic resin sheet or a wallpaper, and in particular, adopts a method of filling using a centrifugal force when filling a molten cast iron during roller manufacturing. It is to provide a more robust, strong durability even at high temperatures embossing rollers and a method of manufacturing the same.

In another aspect, the present invention is to provide an embossing roller manufactured through a silicon transfer plate manufacturing process, a silicon transfer tube manufacturing process, a conductive imparting process, a plating alloy pipe manufacturing process, a fusion process step, a cast iron filling process step.

In addition, the present invention is a plating liquid using a plating apparatus consisting of a titanium basket having a pore on the outer circumferential surface to spray the plating solution, a plating frame support for lifting the plating mold to the upper portion of the plating liquid and a spray preventing plate formed to prevent the plating frame from eroding. It is intended to provide a plating apparatus for plating by spinning in a spiral manner.

The present invention relates to a method for producing an embossing roller for embossing a surface of a synthetic resin sheet or a wallpaper, and an embossing roller and a plating apparatus thereof.

Therefore, the present invention will be described in detail with the drawings shown.

That is, the present invention manufactures an embossing roller through the following steps, the process of the first step is shown in FIG.

The first step is a manufacturing process of the silicon transfer plate 11 which is embossed by applying silicon to the transfer frame 10 to which the surface of the synthetic resin sheet or wallpaper is transferred.

That is, a silicone layer is applied on the transfer frame in which the appearance is transferred from the surfaces of sheets, sheets, wallpaper, and leather.

Next, the second step is as shown in Figures 1 and 2, the silicon transfer plate 11 through the manufacturing process and the silicon transfer plate (11) removed from the transfer frame 10 to form a silicon tube Tube 20 goes through the manufacturing process.

That is, in the transfer frame 10 and the silicon transfer plate layer 11 formed of two layers in one step, only the silicon transfer plate layer is detached and rolled into a cylindrical tube like a roller as shown in FIG. It is a process.

The next third step is an electroconductive imparting process of coating the alloy film 21 by spraying an alloy liquid (nickel or chromium) to impart conductivity for plating on the inner circumferential surface of the silicon transfer tube 20.

That is, as shown in Figure 3, the inner circumferential surface of the silicon transfer tube 20 in order to facilitate the detachment and ease of plating in the prior invention in the operation of spraying the silver liquid, the present invention is a phenomenon that the silver film is corroded In order to prevent the sprayed molten alloy solution.

At this time, the alloy liquid is sprayed a variety of metals can be used, the most useful metal will be nickel or chromium.

Next, in the fourth step, as shown in FIG. 4, the electroplating process is performed by immersing the plating solution of the plating apparatus on the silicon transfer tube 20 coated with the alloy film 21 on the inner circumferential surface thereof. And the like to form a plating alloy tube to be formed.

That is, a process of replating the alloying solution to the inner circumferential surface of the alloy film 21 thinly coated on the inner circumferential surface of the silicon transfer tube 20, the method is the electroplating method of "+" titanium basket as shown in Figure 8 The plating proceeds until the alloy liquid (nickel or the like) contained in the plate is coated on the inner surface of the silicon transfer tube 20 charged with "-"

In the next step, in the fifth step, the fusion process of rotating the plated alloy pipe (shown in FIG. 5; 22) manufactured through the above steps, and pouring the cast iron 30 thereinto fusion to the inner circumferential surface using centrifugal force This is going on.

That is, as shown in FIG. 6, if the molten cast iron 30 is put into the plating alloy tube 22 and the plating alloy tube 22 is rotated at high speed, the molten cast iron is plated alloy tube by centrifugal force. Strongly adhered to the inner circumferential surface of the stiffened.

Accordingly, the cast iron layer 30 does not generate bubbles and has strong durability.

Next, the final step is the sixth step through the fusion process, the casting cast iron filling the cast iron (30 ') between the shaft 36 is inserted into the plating alloy pipe fused to the outer peripheral surface cast iron 30 The process proceeds.

That is, the cast iron 30 'is poured into the space portion between the shaft 36 and the plated alloy pipe 22 to which the primary cast iron layer 30 is applied to harden.

Therefore, the embossing roller of the present invention manufactured by the above method is durable even when used at high temperature and high pressure, and is capable of precise surface treatment.

Then, the structure of the embossed roller manufactured by the above method will be described in detail with reference to FIG. 7.

That is, on the outermost surface, there is a plating alloy tube layer 22 with an embossed alloy layer (nickel or the like), and the first cast iron layer 30 fused by centrifugal force is formed therein.

Next, a secondary cast iron layer 30 ′ formed by pouring molten cast iron is cured, and a shaft 36 is formed at the center thereof.

The following is another embodiment of the method for manufacturing the embossing roller of the present invention is a method of achieving the process from step 1 to step 3 through the silicon transfer tube produced in one process.

That is, this is to use the conductive graphite fine particles in the silicon transfer tube 20 coated with the alloy film 21, which imparted conductivity to the inner circumferential surface of the silicon transfer tube 20 through the second and third steps.

Therefore, conductive graphite particles are mixed with resins (silicone resin, epoxy resin, PU resin, etc.) capable of forming a silicon layer on the transfer plate, but the ratio of graphite is 50:50.

Then, by dispersing them by force, to manufacture a silicon transfer tube capable of the next step of plating using the conductivity of graphite.

In addition, there is also a feature of the present invention is a plating apparatus for performing plating, as shown in Figure 8 and Figure 10 of the conventional invention, a plating container for plating and a plating frame wrapped around the outer peripheral surface of the plating alloy tube therein, " It is somewhat similar in that it is a plating apparatus consisting of plating liquid pumps for supplying a plating liquid to a charged titanium basket.

However, in the plating apparatus of the present invention, a tubular titanium basket 43 having pores 42 formed on the outer circumferential surface of the plating liquid pump 40 through the plating liquid pump 40 is formed, and the upper portion of the plating liquid 41 is formed. Furnace plating plate 44 is provided at the bottom of the plating frame base 45 for lifting.

Accordingly, the plating frame is prevented from being corroded, and the injection preventing plate 46 formed to prevent the plating frame 44 from being eroded from the plating solution 41 sprayed onto the plating frame 45 is further prevented. To prevent it.

Therefore, the plating device in which the above-mentioned components (small) are organically combined has a drug flowing into the titanium mesh outline, which is a problem caused by the conventional invention shown in FIG. 10.

The bubble is generated in order to spray the plating liquid 41 in a spiral manner through the pores 42 of the titanium basket 43, thereby preventing the generation of bubbles in advance.

That is, the vortex that is injected and sprayed alloy liquid will be properly evenly sprayed on the embossed portion.

Of course, since the plating mold is completely exposed to the upper portion of the alloy liquid (plating solution), there is no risk of corrosion.

The embossing roller manufacturing method of the present invention is a useful invention in which the manufacturing process is relatively simple and completely solves the phenomenon of the corrosion of the silver film generated in the conventional manufacturing process.

In addition, it is durable to form a cast iron layer using centrifugal force, so that it does not break or deteriorate in thermal conductivity even when used at high temperature and high pressure.

Therefore, it is easy to emboss the appearance of a synthetic resin sheet, leather, etc., and the pattern is delicate.
