A code printer

Abstract

This invention relates to the field of inkjet printing technology, specifically to an inkjet printer, including a main body of an inkjet printing processing device. A first drive motor is installed on the outer wall of the main body of the inkjet printing processing device. When the air pump is started, the inkjet paper located on the upper surface of the second drive chain is attracted by the air extraction holes and thus tightly adheres to the outer wall of the extraction frame. The first drive motor is then started, and the second drive chain begins to move, carrying the inkjet paper adhered to the outer wall. During this movement, the paper is guided by a sliding shaft within an annular groove on the inner wall of the inkjet printing processing device. Due to the suction, the inkjet paper is not easily displaced during this movement. When the paper reaches the center position of the inkjet printing processing device, the inkjet printer is activated, and it begins to print ink onto the inkjet paper on the upper surface of the second drive chain directly below.

Description

Technical Field

[0001] This invention relates to the field of inkjet printing technology, specifically to an inkjet printer. Background Technology

[0002] A coding printer is a non-contact inkjet printing device that prints by ejecting ink particles from nozzles, charging them, and then deflecting them. Because this printing is non-contact, it can be used on uneven surfaces and soft materials. Coding printers offer the advantage of non-contact inkjet printing on targets, reducing the likelihood of printing defects and residues.

[0003] Currently, existing inkjet printers on the market typically use a conveyor to transport the inkjet paper during the continuous and automated printing process on paper and other items. However, the inkjet paper is prone to displacement or falling during transport, and clamping and limiting the transport of the inkjet paper would obstruct the printing position, thus failing to meet practical requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a coding printer to solve the problems mentioned in the background art. To achieve continuous automated printing on paper and other items, a conveying device is typically used to transport coding paper, and coding is performed during the transport process. However, existing coding printers are prone to paper displacement or falling during transport, and clamping and limiting the paper during transport would obstruct the coding position, thus failing to meet practical requirements. To achieve the above objective, this invention provides the following technical solution: a coding printer, including a coding printing processing device body, a first drive motor mounted on the outer wall of the coding printing processing device body, and a third drive gear rotatably disposed at the output end of the first drive motor, wherein two third drive gears are provided;

[0005] The outer walls of the two third transmission gears are meshed with second transmission chains. The outer walls of the second transmission chains have several evenly distributed transmission grooves. The inner walls of the several transmission grooves are rotatably connected to air extraction frames. An air extraction pump is installed on the outer wall of the air extraction frame. Several air extraction frames are provided, and the several air extraction frames are interconnected by corrugated air supply pipes. The corrugated air supply pipes are connected to the interior of the air extraction frames. A soft elastic sheet is fixedly connected to the outer wall of the air extraction frame. A transmission protrusion is fixedly connected to the end of the soft elastic sheet. A first sealing block is fixedly connected to the outer wall of the soft elastic sheet. An air extraction hole is opened on the outer wall of the air extraction frame. The inner contour of the air extraction hole matches the outer contour of the first sealing block.

[0006] As an alternative solution for the inkjet printer described in this invention, the output end of the first drive motor is fixedly connected to a first drive shaft, the other end of the first drive shaft is rotatably connected to the inner wall of the inkjet printing processing device body, and a first drive gear is fixedly connected to the outer wall of the first drive shaft.

[0007] As an alternative solution for the inkjet printer described in this invention, the outer wall of the first transmission gear is meshed with a first transmission chain, the inner wall of the first transmission chain is meshed with a second transmission gear, the inner wall of the second transmission gear is fixedly connected with a second transmission shaft, the other end of the second transmission shaft is rotatably connected to the inner wall of the inkjet printing processing device body, and the outer walls of both the first and second transmission shafts are fixedly connected to the inner wall of the third transmission gear.

[0008] As an alternative solution for the inkjet printer described in this invention, the end section of the transmission protrusion is set to an arc shape, the soft elastic sheet is set to a silicone rubber plate, a return spring is fixedly connected to the outer wall of the first sealing block, and the other end of the return spring is fixedly connected to the inner wall of the suction frame.

[0009] As an optional solution for the inkjet printer described in this invention, the outer wall of the second transmission chain is rotatably connected to a sliding shaft, and a plurality of sliding shafts are provided. The inner wall of the inkjet printing processing device body is provided with an annular groove, the cross-section of the annular groove is set to be annular, and the inner wall of the annular groove is slidably connected to the outer wall of the plurality of sliding shafts.

[0010] As an alternative solution for the inkjet printer described in this invention, a second drive motor is installed on the outer wall of the main body of the inkjet printing processing device, a fourth drive gear is fixedly connected to the output end of the second drive motor, and the other end of the fourth drive gear is rotatably connected to the inner wall of the main body of the inkjet printing processing device.

[0011] As an alternative solution for the inkjet printer described in this invention, the outer wall of the fourth transmission gear is respectively meshed with a first transmission rack and a second transmission rack, and the first transmission rack and the second transmission rack are arranged parallel to each other.

[0012] As an optional solution for the inkjet printer described in this invention, the ends of the first and second transmission racks are respectively fixedly connected to a first movable plate and a second movable plate, and the outer walls of the first and second movable plates are rotatably connected to inkjet paper smoothing rollers.

[0013] As an optional solution for the inkjet printer described in this invention, the inkjet paper smoothing roller and the second transmission chain are arranged parallel to each other.

[0014] As an alternative solution for the inkjet printer described in this invention, an inkjet printer is installed on the outer wall of the main body of the inkjet printing processing device, and the output end of the inkjet printer is arranged perpendicular to the second transmission chain.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In this invention, the inkjet printer first feeds the paper to be printed onto the upper surface of the second transmission chain. Then, the suction pump is started. At this time, the inkjet paper on the upper surface of the second transmission chain is attracted by the suction of the suction hole and thus tightly adheres to the outer wall of the suction frame. Then, the first transmission motor can be started. The second transmission chain will carry the inkjet paper adsorbed on the outer wall and start to move. During the movement, it is guided by the sliding shaft in the annular groove opened in the inner wall of the inkjet printing processing device body. During the movement, the inkjet paper is not easily displaced due to the suction. When it moves to the center position of the inkjet printing processing device body, the inkjet printer is started. The inkjet printer begins to perform inkjet printing operation on the inkjet paper that has moved to the upper surface of the second transmission chain directly below.

[0017] In this invention, when the suction frame corresponding to the inkjet paper moves to the leftmost end following the transmission chain of the second transmission chain, the teeth of the third transmission gear enter the transmission groove, thereby pressing against the transmission protrusion upwards. This causes the transmission protrusion to be subjected to an upward force. Simultaneously, the soft elastic sheet is also subjected to force due to the softness of its silicone rubber. This deformation causes the sealing block to move upwards, penetrating the inner wall of the suction hole and preventing the negative pressure inside the suction hole from adsorbing the inkjet paper. Thus, the inkjet paper is no longer subject to adsorption. This solves the problem that after inkjet printing, the inkjet paper needs to be conveyed and unloaded, but because the suction pump must be continuously running to ensure stable subsequent printing, the inkjet paper adheres to the upper surface of the second transmission chain, making unloading inconvenient.

[0018] In this invention, after the inkjet printer paper is placed above the second transmission chain, the second transmission motor is started. The second transmission motor drives the fourth transmission gear at the output end to rotate. During the rotation of the first transmission rack, the first and second transmission racks on both sides of the outer wall move through meshing. The first and second transmission racks move closer to each other in opposite directions. During the movement of the first and second transmission racks, the first and second movable plates fixedly connected to their corresponding ends move synchronously. The inkjet paper smoothing rollers rotatably connected to the ends of the first and second movable plates also move synchronously. The inkjet paper smoothing rollers move towards each other to smooth the inkjet paper adsorbed on the upper surface of the second transmission chain. This solves the problem that when the paper is adsorbed onto the upper surface of the second transmission chain, wrinkles or unevenness easily occur during placement due to the softness of the paper, which has a certain impact on the quality of the inkjet printing.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1

[0029] This embodiment aims to address the problem that, in order to achieve continuous automated printing on paper and other items, a conveyor device is typically used to transport inkjet paper and print the code during transport. However, existing inkjet printers are prone to paper displacement or falling during transport, and clamping and limiting the paper during transport can obstruct the printing position, thus failing to meet practical requirements. Please refer to [link to relevant documentation]. Figures 1-7 A coding printer includes a coding printing processing device body 1, a first drive motor 2 is installed on the outer wall of the coding printing processing device body 1, and a third drive gear 7 is rotatably provided at the output end of the first drive motor 2, and there are two third drive gears 7.

[0030] The outer walls of the two third transmission gears 7 are meshed with second transmission chains 8;

[0031] The output end of the first drive motor 2 is fixedly connected to the first drive shaft 201, the other end of the first drive shaft 201 is rotatably connected to the inner wall of the main body 1 of the inkjet printing processing device, and the outer wall of the first drive shaft 201 is fixedly connected to the first drive gear 3.

[0032] The outer wall of the first transmission gear 3 is meshed with the first transmission chain 4, the inner wall of the first transmission chain 4 is meshed with the second transmission gear 5, the inner wall of the second transmission gear 5 is fixedly connected with the second transmission shaft 6, the other end of the second transmission shaft 6 is rotatably connected to the inner wall of the main body 1 of the inkjet printing processing device, and the outer walls of the first transmission shaft 201 and the second transmission shaft 6 are both fixedly connected to the inner wall of the third transmission gear 7.

[0033] The outer wall of the second transmission chain 8 is rotatably connected to a sliding shaft 17. Several sliding shafts 17 are provided. The inner wall of the main body 1 of the inkjet printing processing device is provided with an annular groove 18. The cross-section of the annular groove 18 is annular. The inner wall of the annular groove 18 is slidably connected to the outer wall of several sliding shafts 17.

[0034] The outer wall of the main body 1 of the inkjet printing processing device is equipped with an inkjet printer 19, and the output end of the inkjet printer 19 is set perpendicular to the second transmission chain 8.

[0035] In this embodiment: First, the paper to be printed is fed onto the upper surface of the second transmission chain 8. Then, the vacuum pump 905 is started. After the vacuum pump 905 starts, it continuously draws air from the vacuum frame 9 through its output end. The vacuum frame 9 also draws air from adjacent vacuum frames 9 through the corrugated air supply pipe 10. At this time, several vacuum frames 9 draw outside air through their corresponding air extraction holes 11, generating a certain suction force through negative pressure. At this time, the inkjet paper located on the upper surface of the second transmission chain 8 is attracted by the air extraction holes 11 and thus tightly adheres to the outer wall of the vacuum frame 9. Then, the first transmission motor 2 can be started. The first transmission motor 2 drives the first transmission shaft 201 at its output end to rotate. During the rotation of the first transmission shaft 201, the first transmission gear 3 fixedly connected to the outer wall rotates together. At this time, the first transmission chain 4, which is meshed with the outer wall of the first transmission gear 3, rotates under the transmission of the first transmission gear 3. During the rotation of the first transmission chain 4... The second transmission gear 5, which is meshed with the inner wall, rotates. During the rotation of the second transmission gear 5, it will drive the second transmission shaft 6, which is fixedly connected to the inner wall, to rotate synchronously. At this time, the first transmission shaft 201 and the second transmission shaft 6 rotate in the same direction. The third transmission gear 7, which is fixedly connected to the outer wall of the first transmission shaft 201 and the second transmission shaft 6, also rotates in the same direction at the same time. During the rotation of the two third transmission gears 7, they will drive the second transmission chain 8, which is meshed with the outer wall, to rotate together. At this time, the second transmission chain 8 will carry the inkjet paper adsorbed on the outer wall to start moving. During the movement, it is guided by the sliding shaft 17 in the annular groove 18 opened in the inner wall of the inkjet printing processing device body 1. During the movement, the inkjet paper is not easy to move due to the suction force. When it moves to the center position of the inkjet printing processing device body 1, the inkjet printer 19 is activated. The inkjet printer 19 begins to perform inkjet printing operation on the inkjet paper on the upper surface of the second transmission chain 8 that has moved directly below.

[0036] To achieve continuous automated printing on paper and other items, a conveyor system is typically used to transport the inkjet paper and print the code during transport. However, existing inkjet printers are prone to paper displacement or falling during transport. Clamping and limiting the transport of the inkjet paper would obstruct the printing position, thus failing to meet practical requirements.

[0037] Example 2

[0038] This embodiment aims to address the problem that after the inkjet paper has finished inkjet printing, it needs to be conveyed and unloaded. However, because the vacuum pump 905 must be continuously running to ensure stable subsequent inkjet printing, the inkjet paper adheres to the upper surface of the second transmission chain 8, making unloading inconvenient. This embodiment is an improvement based on Embodiment 1. For details, please refer to [link to Embodiment 1]. Figures 1-7 The outer wall of the second transmission chain 8 is provided with several evenly distributed transmission grooves 801. The inner walls of the several transmission grooves 801 are rotatably connected to the air extraction frame 9. The outer wall of the air extraction frame 9 is equipped with an air extraction pump 905. Several air extraction frames 9 are provided. The several air extraction frames 9 are interconnected by corrugated air supply pipes 10. The corrugated air supply pipes 10 are connected to the interior of the air extraction frame 9. A soft elastic sheet 901 is fixedly connected to the outer wall of the air extraction frame 9. A transmission protrusion 902 is fixedly connected to the end of the soft elastic sheet 901. A first sealing block 903 is fixedly connected to the outer wall of the soft elastic sheet 901. An air extraction hole 11 is provided on the outer wall of the air extraction frame 9. The inner contour of the air extraction hole 11 matches the outer contour of the first sealing block 903.

[0039] The end section of the transmission protrusion 902 is set to an arc shape, the soft elastic sheet 901 is set to a silicone rubber plate, and a return spring 904 is fixedly connected to the outer wall of the first sealing block 903. The other end of the return spring 904 is fixedly connected to the inner wall of the air extraction frame 9.

[0040] In this embodiment: After the inkjet paper is finished with inkjet printing, it needs to be conveyed and unloaded. However, since the vacuum pump 905 must be continuously running to ensure the stability of subsequent inkjet printing, it is inconvenient to unload the inkjet paper adhering to the upper surface of the second transmission chain 8. Therefore, during the conveying process, when the vacuum frame 9 corresponding to the inkjet paper moves to the leftmost end with the transmission of the second transmission chain 8, the transmission groove 801 at the position of the vacuum frame 9 corresponding to the inkjet paper will mesh with the leftmost third transmission gear 7. During the meshing process, the teeth of the third transmission gear 7 will enter the transmission groove 801, thereby pressing against the transmission protrusion 902 and causing the transmission protrusion 902 to move upward. When subjected to an upward force, the transmission protrusion 902 is also subjected to the same force, and the soft elastic sheet 901 is also subjected to the same force. After being subjected to the force, the soft elastic sheet 901 will deform due to the softness of the silicone rubber sheet. After the soft elastic sheet 901 deforms, it will move the sealing block 903 upward. Since the outer contour of the sealing block 903 matches the inner contour of the air extraction hole 11, the sealing block 903 will penetrate the inner wall of the air extraction hole 11 when it moves upward, preventing the negative pressure in the air extraction hole 11 from adsorbing the inkjet paper. At this time, the inkjet paper is no longer subjected to adsorption force. After the second transmission chain 8 continues to move, it will fall into the pre-prepared container for collection through the left bend of the second transmission chain 8.

[0041] This invention addresses the problem that after the inkjet paper has finished inkjet printing, it needs to be conveyed and unloaded. However, because the vacuum pump 905 must be continuously running to ensure the stability of subsequent inkjet printing, the inkjet paper adheres to the upper surface of the second transmission chain 8, making it inconvenient to unload.

[0042] Example 3

[0043] This embodiment aims to address the problem that when paper is adsorbed onto the upper surface of the second drive chain 8, its softness can easily cause wrinkles or unevenness during placement, which can negatively impact the quality of the inkjet printing. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figures 1-7 The outer wall of the main body 1 of the inkjet printing processing device is equipped with a second drive motor 12. The output end of the second drive motor 12 is fixedly connected to a fourth drive gear 13. The other end of the fourth drive gear 13 is rotatably connected to the inner wall of the main body 1 of the inkjet printing processing device.

[0044] The outer wall of the fourth transmission gear 13 is respectively meshed with the first transmission rack 14 and the second transmission rack 15, and the first transmission rack 14 and the second transmission rack 15 are arranged parallel to each other.

[0045] The ends of the first transmission rack 14 and the second transmission rack 15 are respectively fixedly connected to the first movable plate 1401 and the second movable plate 1501, and the outer walls of the first movable plate 1401 and the second movable plate 1501 are rotatably connected to the inkjet paper smoothing roller 16.

[0046] The inkjet paper smoothing roller 16 and the second drive chain 8 are arranged parallel to each other.

[0047] In this embodiment: When the paper is adsorbed onto the upper surface of the second transmission chain 8, due to the softness of the paper, it is easy for wrinkles or unevenness to occur during placement, which will have a certain impact on the quality of the inkjet printing. Therefore, after the inkjet printing paper is placed above the second transmission chain 8, the second transmission motor 12 is started. The second transmission motor 12 will drive the fourth transmission gear 13 at the output end to rotate. During the rotation of the first transmission rack 14, it will drive the first transmission rack 14 and the second transmission rack 15 on both sides of the outer wall to move through the meshing relationship. The first transmission rack 14 and the second transmission rack 15 will move closer to each other in the opposite direction. During the movement of the first transmission rack 14 and the second transmission rack 15, the first movable plate 1401 and the second movable plate 1501 fixedly connected at their corresponding ends will move synchronously. The inkjet printing paper smoothing roller 16 rotatably connected at the ends of the first movable plate 1401 and the second movable plate 1501 will also move synchronously. The inkjet printing paper smoothing roller 16 will move towards each other to smooth the inkjet printing paper adsorbed on the upper surface of the second transmission chain 8.

[0048] This addresses the issue that when paper is adsorbed onto the upper surface of the second drive chain 8, its softness can easily cause wrinkles or unevenness during placement, which can negatively impact the quality of the inkjet printing.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
