Description

Inkjet printer modification method

The present invention relates to a method of retrofitting an ink jet printer. The present invention is based on a Chinese patent application filed on May 10, 2012, the application number of which is incorporated herein by reference.

Inkjet printers are a common type of printer on the market. The ink jet printer works by using an ink container as an ink source, and the ink is transported to the print head via a corresponding ink flow path, and the ink is ejected from the print head nozzle onto a printing medium such as paper by a printing signal.

Referring to FIG. 1 and FIG. 2, a conventional inkjet printer 1 mainly includes a housing 11 and a printing module housed in the housing. The printing module further includes a base 12, a waste ink recovery bin 13 mounted on the base 12, a movement 14 and a rotating spindle 16 for driving the printing medium to feed. The movement 14 is provided with a printing cart 141 for accommodating an ink supply cartridge (not shown), and the bottom of the printing cart 141 is provided with a printing nozzle (not visible in the drawing). A paper guide member 121 is further disposed on the base 12, and the paper guide member 121 is for holding printing paper (not shown) and guiding the printing paper in the direction of the movement 14. The waste ink recovery bin 13 is used to recover the ink for cleaning the print head.

Referring to FIG. 3, the rotating main shaft 16 is mounted on the upper surface of the base 12, and the bottom of the movement 14 extends in the direction of the base 12 with a cylindrical elastic body 142. The rotating main shaft 16 and the cylindrical elastic body 142 abut each other with a certain pressure therebetween, so that the rotating main shaft 16 is prevented from jumping in the radial direction. When the printer is in operation, the printing paper is outputted from the gap reserved between the base 12 and the movement 14 in the direction A, and when the printing paper is supplied to the contact point of the rotating main shaft 16 and the cylindrical elastic body 142, since the paper is thin, printing The paper is pressed by the rotating main shaft 16 and the cylindrical elastic body 142 and continues to be fed in the A direction, and the printing paper then passes through the printing area of the printing cart 141 and finishes printing. Among them, the rotation speed of the rotating main shaft 16 and the reciprocating speed of the printing carriage 141 are controlled by a preset program of the printer, and the two need precise matching to ensure a good printing effect.

A flatbed printer mainly refers to a printer that uses a plate-shaped medium as a printing medium, for example, a plate made of a material such as ceramic, wood, or plastic. There is no substantial difference between the flatbed printer and the ordinary inkjet printer in the printing principle. The main difference between the two is the material and conveying structure of the printing medium. The printing medium of a common inkjet printer is usually paper. In order to reduce the volume of a common inkjet printer as much as possible, the paper path is usually designed as a curved structure; the printing medium of the flatbed printer is hard medium, and cannot Bend, the print media path must be straight.

Figure 11 is a schematic view showing the structure of a portion of the flatbed printer after the modification of the present invention is completed.

Step 1: A conventional ink jet printer 1 as shown in Fig. 1 is provided. The screws on the housing 11 of the ink jet printer 1 are taken out to separate the housing 11 from the printing mold components. Further, the printing mold component is disassembled into a portion such as the base 12, the movement 14, and the rotating main shaft 16 as shown in FIG.

Step 2: The paper guiding member 121 of the base 12 is cut off, and the cut base is as shown in FIG. 4 .

Step 3: As shown in FIG. 5, the waste ink recovery bin 13 on the base 12 is cut along the illustrated pattern, and the base is split into a base remaining portion 129 and a waste ink recovery bin 13.

Step 4: Referring to Fig. 6, a platform 2 is provided to mount the remaining portion 129 of the base and the waste ink recovery bin 13 shown in Fig. 5 to the platform 2, respectively. Further, a pad (not visible in the figure) is added between the waste ink recovery bin 13 and the platform 2, and the height of the pad 21 is substantially the same as the thickness of the preset print template 4 (shown in FIG. 10, the same below). the same. That is to say, with the platform 2 as a reference surface, the bottom of the waste ink recovery bin 13 is higher than the bottom of the remaining portion 129 of the base. The rotating spindle 16 is mounted back to the original position of the remaining portion 129 of the base. In order to prevent the rotating spindle 16 from jumping in the radial direction, the rotating spindle 16 can be further fixed by the U-bolt 3.

Step 5: The movement 14 is mounted on the remaining portion 129 of the base and the waste ink recovery bin 13. Further, a spacer 22 is added to the bottom of the movement 14, and the height of the spacer 22 is substantially the same as the thickness of the preset printing template 4. Since the waste ink recovery bin 13 and the movement 14 are increased by the same height with respect to the platform 2, the distance between the print head on the movement 14 and the waste ink recovery bin 13 is still the same as that before the modification. When the print head performs the cleaning process, it can still form a good seal with the waste ink recovery bin 13.

Step 6: The first print template bracket 31 is added to the front portion of the base remaining portion 129 in the printing template feeding direction, and the second print template bracket 32 is added to the rear portion of the base along the printing template feeding direction. Referring to FIG. 8, a first conveying roller 313 is disposed on a surface of the first printing template bracket 31, and a second conveying roller 323 is disposed on a surface of the second printing template bracket 32. The bottom surface of the printing template 4 is tangent to the second conveying roller 323 and the rotating main shaft 16, so that the printing template 4 can always be in the same plane when the printing is fed.

Step 7: Referring to FIG. 9, the paper exit 111 of the printer casing 11 is further grooved, and the rear surface of the printer casing 11 opposite to the paper exit 111 is also grooved (not visible in the drawing). The purpose of the above-described grooving is to leave a feed space for the print template 4. The slotted casing 11 is overlaid on the modified flatbed printer.

Referring to Fig. 11, when the printer modification is completed, the wheelbase between the rotating main shaft 16 and the cylindrical elastic body 142 coincides with the thickness of the printing template 4. Thus, when the printing template 4 enters between the rotating main shaft 16 and the cylindrical elastic body 142, the printing template 4 will be squeezed by the two, and a frictional force is generated between the rotating main shaft 16 and the printing template 4, so that the printing template 4 is printed. It can be smoothly supplied to the print area to complete the printing.

In the above steps, the rotating main shaft 16 is first separated and reassembled from the base 12, and the purpose thereof is to avoid interference of the rotating main shaft 16 when the waste ink recovery bin 13 is cut, thereby causing damage to the rotating main shaft 16. Therefore, for the present modification method, the separation and reassembly of the rotating spindle 16 is a step that can be omitted, but in such a case, the operator should be very careful to avoid damage to the rotating spindle.

In the above steps, the step of cutting the paper guiding member 121 is also determined as the case may be. The paper guide member 121 may not be provided in some printers, so the step of cutting out may be omitted.

According to the modification method of the present invention, the modified flatbed printer uses the original system on the supply system of the printing template. Therefore, the rotation speed of the printing shaft in the flatbed printer matches the speed of the reciprocating motion of the printing vehicle very accurately, thereby ensuring the tablet. The printer has good printing results.
