Description

TECHNICAL FIELD [A layer of printing manufacturing device for plastic goods}

The present invention relates to a printing apparatus for plastic extrusion molded products, and more particularly, extrusion molding and printing process of plastic extruded products such as building interior and exterior materials are performed in one line, but when the interior and exterior materials for construction are determined to be defective, printing is automatically stopped. To prevent damage to the printing roller made of silicon material, and to install a separate ink transfer roller made of silicon material to supply ink coating amount more uniformly and accurately.

As a plastic extrusion molded product, various kinds of interior and exterior materials with beautiful patterns printed on the surface are used to decorate the interior of a building beautifully. In the past, the interior and exterior materials were manufactured from solid wood or plywood, but the cost is high, durability is weak, and easily decayed. Recently, the interior and exterior materials are extrusion molded into synthetic resin products, and various patterns are printed on the surface thereof.

Such building interior and exterior materials are processed by putting synthetic resins into an extrusion molding machine, extruding and storing raw materials of interior and exterior materials, and putting them in a separate printing process. Multi-color mixed color is applied, and this ink applicator is installed so that the lower part of the copper plate roller, which is imprinted on the surface of building interior and exterior materials, is immersed in the ink container, and the ink roller and copper plate which bury the ink on the pattern of the copper plate roller It consists of a silicon roller that is interviewed at the same time on the surface of the roller and the building interior and exterior materials and receives ink from the pattern engraving area and applies the pattern to the surface of the building interior and exterior materials. The ink is continuously buried and the ink is transferred to the copper roller roller that is interviewed. It is possible to transfer the ink corresponding to the pattern of the surface of the copper roller roller to the silicon roller interviewed with the copper roller, and the silicon roller can apply the ink having the pattern on the surface of the interior and exterior building materials, Two or three ink spreaders are installed in succession only in color, so that a pattern having various mixed colors of 2 ton or 3 ton can be applied.

However, when loading and storing the internal and external raw materials as described above and put them in a separate line, it takes a lot of work time, resulting in poor productivity, as well as poor surface condition due to the inflow of foreign matters, and extrusion molding the internal and external materials. Since the lines for printing the interior and exterior materials should be separate, there are a lot of space constraints due to the vast amount of equipment, and the cost of the equipment increases.

Therefore, in recent years, the extrusion molding and printing process of the building interior and exterior materials, which are plastic extruded products, are sequentially performed in one line, thereby solving the above problems. In this case, the width and thickness of the interior and exterior materials for construction are not uniform or many. Since the printing is continuously performed even in the case of defects such as bending, holes, or cracks, a problem arises in that the silicon roller performing the actual printing is in contact with the defective portion of the extruded molded product as it passes and scratches or tears.

In addition, it is difficult to apply the ink supplied from the ink container uniformly and evenly over the entire copper plated roller because the copper roller and the ink roller inscribed with the pattern to be printed are in direct contact with each other. Of course, it is necessary to have a means of, of course, it is impossible to obtain a high quality printing surface, and the material loss due to frequent defects is inevitable structural problems.

Therefore, the present invention was devised to solve these problems, and the extrusion frame and the printing process of the building interior and exterior materials, which are plastic extruded products, are sequentially performed in one line, but the support frame on which each roller of the ink applicator is installed is fixed to the frame. And a movable frame connected to the front and rear removably. The fixed frame is equipped with a silicon roller, and the movable frame is equipped with a copper roller, an ink transfer roller, an ink roller, and an ink container, and between the fixed frame and the movable frame. The cylinder is connected in the horizontal direction, the cylinder is connected in the upward direction to the axis of the silicon roller, and the optical sensor is provided in front of the extruder. When the interior and exterior materials for building are judged to be defective by this optical sensor, the movable frame is retracted to the silicon. Spaced apart between the roller and the copper plated roller to block rotational transfer, and then By raising the roller and separating it from building interior and exterior materials, it automatically stops printing to prevent damage to the silicon roller due to contact with defective parts of extruded products and prevents the manufacturer of defective interior and exterior materials, thereby improving the reliability of the product. The present invention is to provide a plastic extrusion molding machine.

In another aspect, by installing an ink transfer roller made of a flexible silicone material between the copper plate roller stamped with various patterns and the ink roller to supply the ink by immersing a part of the body to supply ink, the ink applied to the copper plate roller Since it is always evenly and uniformly applied, it is possible to form a high quality printing surface and to prevent occurrence of printing surface defects.

The guide pin 207a is inserted into the long hole 206a formed in the horizontal direction, respectively, and the movable frame 207 is connected to the back and forth, and the fixed frame 206 is provided with a silicon roller 205 and a movable frame. A copper plate roller 201, an ink transfer roller 204, an ink roller 202, and an ink container 203 are respectively installed at 207, and the piston rods 209a are connected to both fixed frames 206, respectively. Each movable frame 207 adjacent to the fixed frame 206 has a rear end of each cylinder 209 for operating each piston rod 209a. Each side is connected in the horizontal direction, and each of the fixed frame 206 is formed with a slider 206b to be opened in the upward direction, so that the shaft 205a of the silicon roller 205 is placed thereon, and the silicon roller ( The cylinders 208 are respectively provided on the upper portions of the shafts 205a of the 205, and the piston rods 208a are connected to the shafts 205a of the silicon roller 205, respectively. If (i) is defective, the cylinders 209 and 208 operate sequentially to block ink and rotational transfer. Each roller 201, 202, 204, 205 is engaged with each other. The power is received by the motor (not shown) of the silicon roller 205 is configured to be cut off the power when the silicon roller 205 is spaced apart from the copper roller 201.

Although not shown, a controller is provided to control the system so that each device is sequentially operated in a parallel state, and when a detection signal of the optical sensor 300 is input to the controller, the bending, width or Based on the uniformity of the thickness, the presence or absence of holes, the presence of cracks, and the like, a comparison operation with previously input data is used to determine whether there is a defect.

In the drawing, reference numerals 213 and 214 denote sliders for adjusting the axial positions of the copper roller 201 and the ink transfer roller 204, and 215 and 216 denote adjustment bolts.

The plastic extrusion molded product printing apparatus according to the present invention configured as described above functions as follows.

First, when the building interior and exterior interior material (i), which is an extruded synthetic resin material, is extruded through the extrusion molding machine 100, the optical sensor 300 passes in front of the building, and in this process, the optical sensor 300 is a building interior and exterior material (i). Detects the degree of warp, the uniformity of the width or thickness, the presence or absence of holes, the presence of cracks, etc. The detection signal is automatically input to the controller to determine whether or not the interior and exterior building materials (i) for building, the interior and exterior building materials (i If () is normal, the continuous work proceeds, and if it is determined that the defect is bad, each cylinder 209, 208 of the ink applicator 200 is sequentially operated.

That is, when the interior and exterior building materials (i) for construction is normal, it passes through the installation section of the optical sensor 300 and flows into the ink applicator 200, and the ink roller 202 of the ink applicator 200 has a lower portion in the ink container 203. It is dipped so that the ink is continuously buried on the surface, the ink can be delivered to the copper plated roller 201 via the ink transfer roller 204 that is interviewed, and the silicon roller 205 interviewed with the copper plated roller 201. ) And the ink corresponding to the pattern of the surface of the copper plated roller 201, the silicon roller 205 can be applied to the surface of the building interior and exterior materials (i), the ink in which the pattern is formed, the same type of ink Abandonment 200 is installed only two or three in succession only different colors, it is possible to apply a pattern having a color of 2 tons or 3 tons.

On the contrary, when the interior and exterior building material (i) for building is determined to be defective by calculating the detection signal through the optical sensor 300 in the controller, the fixed frame 206 and the movable frame 207 of the ink applicator 200 as shown in FIG. 3. ), The movable frame 209 is driven backward by driving the cylinder 209 provided between the, and when the movable frame 207 is reversed, the copper plate roller 201 and the ink transfer roller (201) installed in the movable frame 207 204, the ink roller 202, and the ink container 203 are all retracted so as to be spaced apart between the copper roller 201 and the silicon roller 205, thereby transferring ink and power from the copper roller 201. Is blocked.

However, since some ink was transferred from the copper plated roller 201 to the silicon roller 205 before the power transmission was interrupted, the surface of the silicon roller 205 was cleaned separately when the line was restarted after removing the ink. In this invention, even after the silicon roller 205 and the copper plated roller 201 are spaced apart, the interior and exterior building materials (i) are transferred a little more so that the silicon roller 205 is rotated two to three more times in place. In this case, the ink deposited on the surface of the silicon roller 205 is completely removed, and then the cylinder 208 installed on the shaft 205a of the silicon roller 205 is operated to operate as shown in FIG. As such, when the silicon roller 205 is raised, the silicon roller 205 is prevented from contacting the silicon roller 205 from the defective occurrence portion of the interior and exterior materials passing through the building interior and exterior materials i. By, and can prevent in advance the damage of the silicon roller, after removing the bad section of the building interior and exterior materials (i) is to resume operation of the line again.

After the interior and exterior building material (i) has passed through the ink applicator 200, it is cut to a certain length through a cutter through a U.V. coating machine, a U.V. dryer, and uses such building interior and exterior material for interior construction.

On the other hand, when the amount of ink set from the ink delivery roller is applied to the copper roller, the operator adjusts the gap between the copper roller and the ink delivery roller to finely adjust the amount of ink applied while tightening or releasing the adjusting bolt of the ink delivery roller. It can be adjusted and uniformly applied at all times to prevent defects caused by the printing surface during printing.

In addition, since the ink transfer roller is made of a flexible silicone material, the ink applied to the ink roller can be evenly applied with the same thickness.

As described above, the present invention can improve the workability and productivity because the extrusion molding process and the printing process are composed of one line, and the power of the silicon roller of the ink printer when the building interior and exterior materials, which are plastic extrusion moldings, are defective. Since the rollers are rotated a few laps while blocking the transmission, the silicon roller is also spaced apart from the interior and exterior materials for construction, preventing damage to the damaged parts of the interior and exterior materials passing through, and preventing the damage of the silicone rollers. It is very useful to improve the efficiency of the work by immediately operating the device without the need for cleaning.
