Printing method and printer with fine-tunable print head

Abstract

The present invention discloses a method for fine-tuning a print head and a printer, which relates to the technical field of printers and includes a machine body, a paper feed assembly, and a printing assembly. The front outer side of the machine body is provided with a paper feed assembly, and the paper feed assembly includes a paper feed ramp, a push seat, a card slot, a positioning plate, and a locking button. When the resistor of the present invention is working, the electromagnet will also lose power. After the electromagnet loses power, the lifting seat will be ejected by the reset spring due to the loss of adsorption force. During the ejection process, the lifting seat can drive the print head to move downward through a connecting rod. The print head is located at a position slightly higher than the top of the ink outlet. By displacing the print head, the print head can extend out of the ink outlet, so that the print head can act as a guide head to cooperate with the dripping of ink. At the same time, the downward displacement of the lifting seat can also cooperate with the bubbles caused by evaporation to push the ink out, which can reduce the situation where the ink cannot drip smoothly due to reasons such as excessive ink viscosity and insufficient heating head temperature.

Description

Technical Field

[0001] The present invention relates to the technical field of printers, and in particular to a printing method with fine-tunable print heads and a printer. Background Art

[0002] A printer is a computer output device used to print computer processing results onto a medium. There are many types of printers. Depending on whether the printing element strikes the paper, they are categorized as impact printers and non-impact printers. Based on the structure of printed characters, they are categorized as full-width printers and dot-matrix printers. Based on the way a line of characters is formed on paper, they are categorized as serial printers and line printers. Based on the technology used, printers are categorized as cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, and LED printers. Inkjet printers are the most widely used, and are widely used in the production of books, posters, promotional posters, and advertising banners.

[0003] Large papers such as posters, promotional posters, and advertising canvases are usually stored in a roll-up format. This causes the paper to easily curl during printing, resulting in misaligned prints. Common inkjet printers on the market are usually unable to resolve this problem. In addition, due to various reasons, inkjet printers are prone to various problems such as ink stains remaining on the paper and ink breaks resulting in missing prints.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a printing method and printer with fine-tuning of the print head are proposed. Summary of the Invention

[0015] Furthermore, the expansion airbag is connected to the re-suction chamber through an electric control valve, and the re-suction chamber is connected to the reflux chamber.

[0016] The present invention provides a printing method and a printer with fine-tunable print head, which have the following beneficial effects:

[0017] 1. The staff of the present invention can release the lock between the paper feeding ramp and the pushing seat by loosening the locking button. The staff can adjust the spacing between the positioning plates on both sides of the top of the paper feeding ramp by sliding the pushing seat. The paper feeding ramp can limit the paper entering the device to prevent the paper from being deflected during the printing process when entering the device. By adjusting the spacing between the positioning plates, the device can use paper of different sizes. After the paper enters the body, the driving roller stops rotating. At this time, the suction pump works, which can transmit the suction force to the adsorption groove of the adsorption seat through the connecting pipe. Through this design, The adsorption seat adsorbs the paper, and after the paper is adsorbed, the electric-controlled displacement seat works to drive the adsorption seat to move toward the edge of the machine body. The displacement of the adsorption seat can stretch and straighten the paper. Because large paper is often rolled up during storage, it is easy for the paper to be misplaced due to rewinding during printing. However, this design can also prevent accidental displacement of the paper during printing for ordinary paper. The positioning of the positioning plate and the stretching and locking of the adsorption seat can greatly improve the printing accuracy of the equipment.

[0018] 2. When the resistor of the present invention is working, the electromagnet will also lose power at the same time. After the electromagnet loses power, the lifting seat will be ejected by the reset spring due to the loss of adsorption force. During the ejection process, the lifting seat can drive the print head to move downward through the connecting rod. The print head is located at a position slightly higher than the top of the ink outlet hole. By displacing the print head, the print head can extend out of the ink outlet hole, which enables the print head to act as a guide head to cooperate with the dripping of ink. At the same time, the downward displacement of the lifting seat can also cooperate with the bubbles caused by evaporation to push the ink out, which can reduce the situation where the ink cannot drip smoothly due to reasons such as high ink viscosity and the heating head temperature not being reached, which can improve the stability of the equipment. After the ink dripping is completed, the electromagnet is energized again, which can retract the print head, which enables the print head to frequently move in and out of the ink outlet hole, which can effectively avoid the blockage of the ink outlet hole.

[0019] 3. The suction integrated pump of the present invention transmits gas, which can allow the gas to enter the expansion airbag through the vent pipe, the first connecting groove, the connecting pipe, and the second connecting groove, so that the expansion airbag can be expanded. After the expansion airbag is expanded, the opening diameter of the ink outlet hole can be adjusted, which allows the ink output of the device to be adjusted. By adjusting the ink output amount by the print head, the device can achieve a larger unit coating area when printing graffiti and heavy fonts, which can avoid the need for a large movement frequency of the printing plate and paper to achieve a large coating area, which can improve printing efficiency and speed. When printing small fonts, the font accuracy can be improved by reducing the ink output. It can effectively reduce the blurring of the edges of the fonts. After the ink dripping is completed, the integrated suction pump works to draw back the gas inside the inflated airbag. During the withdrawal process, the electronically controlled valve opens, allowing the inflated airbag to communicate with the back-suction chamber, which enables the suction force to be transmitted to the reflux chamber. After the ink dripping is completed, residual ink will remain at the tip of the print head and will be transmitted to the reflux chamber through the suction force, which enables the device to suck the residual ink into the back-suction chamber for storage. This can effectively prevent the residual ink from dripping onto the paper, causing stains on the paper. This function, combined with the retraction of the print head and the adsorption of the paper by the adsorption seat, can greatly prevent the paper from rubbing with ink.

[0031] The specific operation is as follows: before using the device, the staff can release the lock between the paper feeding inclined plate 201 and the pushing seat 202 by loosening the locking button 205. The staff can slide the pushing seat 202 to adjust the spacing of the positioning plates 204 on both sides of the top of the paper feeding inclined plate 201. The paper feeding inclined plate 201 can limit the paper entering the device to prevent the paper from being deflected during the printing process when entering the device. By adjusting the spacing of the positioning plates 204, the device can use paper of different sizes. After the spacing adjustment of the positioning plates 204 is completed, the staff will insert the paper to be printed into the body 1. At this time, the driving roller 4 works to drive the paper into the body 1. Thanks to the positioning of the positioning plates 204, the paper can be effectively prevented from tilting. After the paper enters the body 1, the driving roller 4 works to drive the paper into the body 1. The movable roller 4 stops rotating, and the suction pump 501 works at this time, which can transmit the suction force to the adsorption groove 504 of the adsorption seat 503 through the connecting tube 502. Through this design, the adsorption seat 503 can adsorb the paper. After the paper is adsorbed, the electric-controlled displacement seat 505 works, which can drive the adsorption seat 503 to move toward the edge of the body 1. The displacement of the adsorption seat 503 can stretch and straighten the paper. Because large paper is often rolled up during storage, it is easy for the paper to be misplaced due to rewinding during printing. For ordinary paper, this design can also avoid accidental displacement of the paper during printing. The positioning of the positioning plate 204 and the stretching and locking of the adsorption seat 503 can greatly improve the printing accuracy of the equipment.

The vent pipe 702 is connected to the second communication groove 716 through the first communication groove 714 and the communication pipe 715. The second communication groove 716 is connected to the expansion airbag 709. The expansion airbag 709 is connected to the back suction chamber 711 through the electric control valve 710. The back suction chamber 711 is connected to the reflux chamber 713. A one-way reflux valve 718 is provided between the back suction chamber 711 and the reflux chamber 713.

[0033] The specific operation is as follows: after the paper positioning is completed, the electric control screw 602 works to drive the sliding seat 603 to move inside the support seat 601, so that the printing plate 606 can move to the printing position specified by the paper. At this time, the resistor 705 works to heat the heating head 706. After the heating head 706 is heated, the ink around it can evaporate, thereby generating bubbles around the heating head 706. After the bubbles are generated, they can push the nearby ink to move, so that the ink can drip out from the ink outlet 609. After the ink drips onto the surface of the paper, the paper can be printed. At the same time as the resistor 705 is working, the electromagnet 717 will also be de-energized. After the electromagnet 717 is de-energized, the lifting seat 704 will be reset by the spring 703 due to the loss of adsorption force. When the lifting seat 704 is ejected, the connecting rod 707 can be used to drive the print head 708 to move downward. The print head 708 is located at a slightly higher position than the top of the ink outlet 609. By displacing the print head 708, the print head 708 can extend out of the ink outlet 609, which enables the print head 708 to act as a guide head to cooperate with the dripping of ink. At the same time, the downward displacement of the lifting seat 704 can also cooperate with the bubbles caused by evaporation to push the ink out. This can reduce the situation where the ink cannot drip smoothly due to reasons such as the ink viscosity being too high or the temperature of the heating head 706 not being reached. This can improve the stability of the device. After the ink dripping is completed, the electromagnet 717 is energized again, which can retract the print head 708. 8 can frequently move in and out of the ink outlet hole 609, which can effectively avoid the blockage of the ink outlet hole 609. The suction integrated pump 605 can transmit gas, which can allow the gas to enter the expansion airbag 709 through the vent pipe 702, the first connecting groove 714, the connecting pipe 715, and the second connecting groove 716, so that the expansion airbag 709 can be expanded. After the expansion airbag 709 is expanded, the opening diameter of the ink outlet hole 609 can be adjusted, which makes the ink output of the device adjustable. By adjusting the ink output amount through the print head 708, the device can achieve a larger unit coating area when printing graffiti and heavy fonts, which can avoid the need for the printing plate and paper to move at a very high frequency to achieve a large coating area, which can improve the efficiency and speed of printing. When printing small fonts, the font accuracy can be improved by reducing the ink output, which can effectively reduce the blurring of the font edges. After the ink dripping is completed, the suction integrated pump 605 works to draw back the gas inside the expansion airbag 709. During the withdrawal process, the electric control valve 710 opens, which enables the expansion airbag 709 to be connected to the back-suction chamber 711, so that the suction force can be transmitted to the reflux chamber 713. After the ink dripping is completed, the residual ink will remain at the tip of the print head 708. The suction force is transmitted to the reflux chamber 713, which enables the device to suck the residual ink into the back-suction chamber 711 for storage. This can effectively prevent the residual ink from dripping onto the paper, causing stains on the paper. This function cooperates with the retraction of the print head 708 and the adsorption of the paper by the adsorption seat 503.This can greatly prevent ink from rubbing against the paper. When the suction integrated pump 605 supplies air to the expansion airbag 709 the next time, the electronically controlled valve 710 opens, allowing air to enter the reflux chamber 713. This allows the residual ink stored in the reflux chamber 713 to flow back into the ink storage chamber 608 through the one-way discharge valve 712. This prevents excessive residual ink in the reflux chamber 713 from entering the expansion airbag 709.

[0034] In summary, the present invention relates to a method and a printer for fine-tuning a print head. When the device is used, first, before use, the staff releases the lock between the paper feed ramp 201 and the push seat 202 by loosening the locking button 205. The staff slides the push seat 202 to adjust the spacing between the positioning plates 204 on both sides of the top of the paper feed ramp 201. The paper feed ramp 201 can limit the paper entering the device to prevent the paper from being deflected during the printing process when entering the device. By adjusting the spacing between the positioning plates 204, the device can use paper of different sizes. After the spacing between the positioning plates 204 is adjusted, the staff inserts the paper to be printed into the body 1. At this time, the driving roller 4 works to drive the paper into the body 1. Thanks to the positioning of the positioning plates 204, the paper can be effectively prevented from tilting.

[0035] Then, after the paper enters the interior of the machine body 1, the driving roller 4 stops rotating. At this time, the suction pump 501 works, and the suction force can be transmitted to the adsorption groove 504 of the adsorption seat 503 through the connecting tube 502. Through this design, the adsorption seat 503 can adsorb the paper. After the paper is adsorbed, the electric-controlled displacement seat 505 works, which can drive the adsorption seat 503 to move toward the edge of the machine body 1. The displacement of the adsorption seat 503 can stretch and straighten the paper. Because large paper is often rolled up during storage, it is easy for the paper to be misplaced during printing due to rewinding. However, for ordinary paper, this design can also prevent the paper from accidentally moving during printing. The positioning of the positioning plate 204 and the stretching and locking of the adsorption seat 503 can greatly improve the printing accuracy of the equipment.

[0036] After the paper is positioned, the electric-controlled screw rod 602 works to drive the sliding seat 603 to move inside the support seat 601, which enables the printing plate 606 to move to the designated printing position of the paper. At this time, the resistor 705 works to heat the heating head 706. After the heating head 706 is heated, the ink around it evaporates, thereby generating bubbles around the heating head 706. After the bubbles are generated, they can push the nearby ink to move, thereby enabling the ink to drip out from the ink outlet 609. After the ink drips onto the surface of the paper, the paper can be printed. At the same time as the resistor 705 is working, the electromagnet 717 will also lose power. After the electromagnet 717 loses power, the lifting seat 704 will be ejected by the return spring 703 due to the loss of adsorption force. During the ejection process, the lifting seat 704 can drive the print head 708 to move downward through the connecting rod 707. The print head 708 is located at a position slightly higher than the top of the ink outlet hole 609. By displacing the print head 708, the print head 708 can extend out of the ink outlet hole 609, so that the print head 708 can act as a guide head to cooperate with the dripping of ink. At the same time, the downward displacement of the lifting seat 704 can also cooperate with the bubbles caused by evaporation to push the ink out. This can reduce the situation where the ink cannot drip smoothly due to reasons such as too high ink viscosity or the temperature of the heating head 706 not being reached, thereby improving the stability of the device.

[0037] After the ink dripping is completed, the electromagnet 717 is energized again, which can cause the print head 708 to retract, so that the print head 708 can frequently move in and out of the ink outlet 609, which can effectively prevent the ink outlet 609 from being blocked. The suction integrated pump 605 supplies gas, which can allow the gas to enter the expansion airbag 709 through the vent pipe 702, the first connecting groove 714, the connecting pipe 715, and the second connecting groove 716, so that the expansion airbag 709 can expand. After the expansion airbag 709 expands, the opening diameter of the ink outlet 609 can be adjusted, which allows the ink output of the device to be adjusted. By adjusting the ink output by the print head 708, the device can achieve a larger unit coating area when printing graffiti and heavy fonts, which can avoid the need for the printing plate and paper to move at a very high frequency to achieve a large coating area, which can improve printing efficiency and speed. When printing small fonts, the font accuracy can be improved by reducing the ink output, which can effectively reduce the blurring of the font edges.

[0038] Finally, after the ink dripping is completed, the suction integrated pump 605 works to draw back the gas inside the expansion airbag 709. During the withdrawal process, the electric control valve 710 is opened, which enables the expansion airbag 709 to be connected to the back-suction chamber 711, so that the suction force can be transmitted to the reflux chamber 713. After the ink dripping is completed, the residual ink will remain at the tip of the print head 708. The suction force is transmitted to the reflux chamber 713, which enables the device to suck the residual ink into the back-suction chamber 711 for storage, which can effectively prevent the residual ink from dripping on the paper, causing the paper to be damaged. In the event of stains on the paper, this function, combined with the retraction of the print head 708 and the adsorption of the paper by the adsorption seat 503, can greatly prevent the paper from being rubbed with ink. When the suction integrated pump 605 supplies air to the expansion airbag 709 next time, the electric control valve 710 is opened to allow gas to enter the reflux chamber 713, which allows the residual ink stored in the reflux chamber 713 to flow back to the ink storage chamber 608 through the one-way discharge valve 712, which can prevent excessive residual ink in the reflux chamber 713 from entering the expansion airbag 709.
