Description

Technical Field

[0001] This utility model relates to the field of printing machine technology, and in particular to an ink cartridge support structure and a gravure printing machine. Background Technology

[0002] In gravure printing machines, the width of the ink cartridge is the same as the width of the gravure roller, thus spanning the entire working width. The ink cartridge needs to be in close contact with the gravure roller so that the gravure roller can carry ink from the ink cartridge to achieve the inking operation.

[0003] However, in actual production, the large width of the ink cartridge makes it prone to deformation, which in turn leads to uneven contact between the ink cartridge and the gravure roller, ultimately affecting the printing effect. Utility Model Content

[0004] To address at least one of the aforementioned technical problems, this utility model proposes an ink cartridge support structure and a gravure printing machine.

[0005] According to some embodiments of this utility model, an ink cartridge support structure is provided, comprising: an ink cartridge, wherein an ink inlet is provided on one side of the ink cartridge; a gravure roller, disposed on the side of the ink cartridge having the ink inlet, and the gravure roller abutting against the ink inlet; and a mounting beam, disposed on the side of the ink cartridge away from the ink inlet, wherein at least two cylinders are disposed on the mounting beam, the at least two cylinders being evenly distributed along the length direction of the mounting beam, and each cylinder being mounted with a cylinder connecting rod, the cylinder connecting rod being fixedly connected to the ink cartridge.

[0006] Based on the above scheme, the ink cartridge and the gravure roller are arranged horizontally. A mounting beam and multiple cylinders are set on the side of the ink cartridge away from the gravure roller. The cylinders are used to push the ink cartridge toward the gravure roller to prevent the ink cartridge from deforming and to ensure uniform contact between the ink cartridge and the gravure roller.

[0007] In some possible implementations, the mounting beam is a square steel tube, the cylinder is mounted on the side of the square steel tube away from the ink cartridge, and the cylinder connecting rod passes through the square steel tube and is connected to the ink cartridge.

[0008] Based on the above scheme, the mounting beam is selected to be a square steel tube. The mounting beam is set parallel to the ink cartridge and the gravure roller, and the structural strength of the mounting beam itself is large enough to ensure that the force applied by the cylinder to the ink cartridge is evenly distributed.

[0009] In some possible implementations, a control module is also included, which is connected to the cylinder and is used to drive and control the cylinder. A pressure sensor is provided on the cylinder connecting rod and is connected to the control module. The pressure sensor is used to obtain the pressure of the cylinder on the ink cartridge.

[0010] Based on the above solution, by detecting the real-time output force of the cylinders through pressure sensors, the output force of each cylinder can be precisely adjusted to ensure that the ink cartridge is subjected to uniform force, thereby ensuring that the ink cartridge can make uniform contact with the gravure roller.

[0011] In some possible implementations, a distance sensor is also included, which is connected to the control module and is used to measure the extension length of the cylinder connecting rod.

[0012] Based on the above solution, a distance sensor is used to further detect whether the ink cartridge has an angular offset, ensuring that the ink cartridge can make uniform contact with the gravure roller.

[0013] In some possible implementations, a motor is also included, which is drivenly connected to the gravure roller and is used to drive the gravure roller to rotate. The control module is connected to the motor and is also used to adjust the speed of the motor.

[0014] Based on the above scheme, the control module can adjust the motor speed according to the detection data of the pressure sensor and the distance sensor, so that the rotation speed of the gravure roller is related to the contact pressure of the ink cartridge, ensuring that the gravure roller can be inked evenly and fully.

[0015] In some possible implementations, a fixing component is also included, which includes a fixing beam and support seats disposed at both ends of the fixing beam, wherein the ink cartridge, the gravure roller and the mounting beam are all fixedly installed between the two support seats.

[0016] Based on the above solution, the gravure roller, ink cartridge, and mounting beam are integrated into one unit by fixing components, which further ensures the stability and reliability of the printing machine during operation.

[0017] According to some other embodiments of the present invention, a gravure printing machine is provided, including an ink cartridge support structure as described in any of the above embodiments.

[0018] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the present invention.

[0032] In gravure printing machines, the gravure roller comes into contact with the ink cartridge. As the roller rotates, it carries ink from the cartridge, achieving inking. However, problems such as insufficient or uneven inking can occur. These issues arise from factors such as excessive distance between the cartridge and the roller, small contact area between the roller and the cartridge opening, and cartridge deformation. Therefore, the contact surface between the cartridge and the roller significantly affects the inking effect, thus impacting the final printed product.

[0033] To solve the above-mentioned technical problems, this utility model provides an ink cartridge support structure, please refer to... Figure 1-2 The structure includes an ink cartridge 1, a gravure roller 5, and a mounting beam 2. The ink cartridge 1 is elongated and horizontally positioned. An ink inlet is provided on one side along its length. The gravure roller 5 is parallel to the ink cartridge 1 and is positioned on the side of the ink cartridge 1 with the ink inlet, and the gravure roller 5 abuts against the ink inlet. The mounting beam 2 is positioned on the side of the ink cartridge 1 away from the ink inlet and is also parallel to the ink cartridge 1. At least two cylinders 3 are provided on the mounting beam 2 and are evenly distributed along the length of the mounting beam 2. Each cylinder 3 is equipped with a cylinder connecting rod 4, which is fixedly connected to the ink cartridge 1. Each cylinder 3 provides a thrust to the ink cartridge 1 through its respective cylinder connecting rod 4, and the direction of the thrust is from the ink cartridge 1 towards the gravure roller 5.

[0034] Based on the above structure, the gravure roller 5 and the ink cartridge 1 are arranged laterally. The ink cartridge 1 is located on the side of the gravure roller 5. A mounting beam 2 is set on the side of the ink cartridge 1 away from the gravure roller 5. The length of the mounting beam 2 matches that of the ink cartridge 1. Multiple cylinders 3 evenly distributed on the mounting beam 2 can apply a thrust to the ink cartridge 1 so that the ink cartridge 1 and the gravure roller 5 are in uniform contact, thereby ensuring uniform ink application on the gravure roller 5 and thus ensuring the final printing effect.

[0035] This embodiment does not limit the specific structure of the mounting beam 2, nor does it limit the material selection. In some cases, the mounting beam 2 can be configured as a square steel tube, with the cylinder 3 installed on the side of the square steel tube away from the ink cartridge 1. The cylinder connecting rod 4 passes through the square steel tube and connects to the ink cartridge 1. The mounting beam 2 based on the square steel tube can ensure sufficient structural strength, thereby ensuring that the force applied by the cylinder 3 to the ink cartridge 1 is evenly distributed. In other cases, the mounting beam 2 can also be made of other structural profiles, such as T-shaped steel with reinforcing ribs, or bent steel plates.

[0036] In one specific embodiment, the mounting beam 2 is made of cast steel or bent steel plate with a plate thickness of 6mm-12mm, a mounting beam thickness of 50mm-80mm, and a height of 120-150mm.

[0037] This embodiment does not limit the number of cylinders 3 on the mounting beam 2. It should be understood that the number of cylinders 3 should be adjusted according to the length of the ink cartridge 1. In one specific case, the printing width of gravure printing is 1600mm-3200mm, and correspondingly, the length of the ink cartridge 1 is also 1600mm-3200mm. Similarly, the length of the mounting beam 2 is also 1600mm-3200mm. Based on this, the number of cylinders 3 can be 3-5. In another specific case, the distance between adjacent cylinders 3 is determined to be 500mm-650mm.

[0038] In this embodiment of the invention, the ink cartridge 1, the gravure roller 5, and the mounting beam 2 are integrated into a single unit via a fixing assembly. Specifically, the ink cartridge support structure further includes a fixing assembly comprising a fixing beam 6 and support seats (not shown in the figure) disposed at both ends of the fixing beam 6. The ink cartridge 1, the gravure roller 5, and the mounting beam 2 are all fixedly mounted between the two support seats. The fixing beam 6 is parallel to the mounting beam 2, and the fixing beam 6 and the support seats at both ends form a mounting platform. The support seats at both ends clamp the gravure roller 5, the ink cartridge 1, and the mounting beam 2. By integrating the gravure roller 5, the ink cartridge 1, and the mounting beam 2 into a single unit, positional misalignment between the gravure roller 5, the ink cartridge 1, and the mounting beam 2 can be avoided, thus preventing uneven ink application and ensuring the stability and reliability of the printing machine during operation.

[0039] One embodiment of the ink cartridge support structure of this utility model also includes a control module. The control module is connected to each cylinder 3 on the mounting beam 2. The control module is used to drive and control each cylinder 3, and can accurately control the output pressure of each cylinder 3, thereby ensuring that the ink cartridge 1 is subjected to uniform force. It should be understood that this embodiment does not limit the specific parameter selection of the cylinder 3. The specifications of the cylinder 3 should be related to the length, thickness and height of the ink cartridge 1.

[0040] In one specific implementation, the printing width of the gravure printing is 1600mm-3200mm, the length of the ink cartridge 1 is also 1600mm-3200mm, and correspondingly, the cylinder 3 can have a diameter of 32mm-40mm, the stroke of the cylinder connecting rod 4 is 25mm-30mm, and the pressure output of the cylinder 3 is 0.15mpa-0.8mpa.

[0041] In some embodiments, the control module can provide feedback control over the output pressure of cylinder 3. Specifically, a pressure sensor is provided on the cylinder connecting rod 4, and the pressure sensor is connected to the control module. The pressure sensor is used to acquire the pressure of cylinder 3 on ink cartridge 1. Based on the above scheme, the control module can accurately acquire the real-time output pressure of each cylinder 3 on ink cartridge 1 through the feedback signals from the pressure sensors on each cylinder connecting rod 4. When uneven output pressure is detected among the cylinders 3, the control module can adjust the output of cylinder 3 in a timely manner, thereby avoiding uneven ink application caused by differences in cylinder 3 output.

[0042] In a further embodiment, the ink cartridge support structure also includes a distance sensor connected to the control module. The distance sensor is used to measure the extension length of the cylinder connecting rod 4. In practical applications, there may be instances where the ink cartridge 1 is misaligned. In such cases, relying solely on the pressure detection of each cylinder 3 is insufficient to accurately adjust the pressure. Therefore, distance measurement is required to ensure that the output pressure of the cylinder 3 is accurate and appropriate. Specifically, the control module acquires the output pressure of each cylinder 3 and the extension length of the corresponding cylinder connecting rod 4. If the output pressure is uniform and the extension length is consistent, it is determined that the ink cartridge 1 is in uniform contact with the gravure roller 5; otherwise, the output of the corresponding cylinder 3 needs to be adjusted.

[0043] This embodiment does not limit the installation position of the ranging sensor. The ranging sensor can be installed on the mounting beam 2, the fixed beam 6, or the support base. This embodiment also does not limit the number of ranging sensors; there can be a single sensor or multiple sensors. In one specific implementation, the number of ranging sensors is the same as the number of cylinders 3. Furthermore, this embodiment does not limit the type of ranging sensor; the ranging sensor can be a radar ranging sensor, an infrared ranging sensor, a magnetic induction ranging sensor, or other types of ranging sensors.

[0044] In this embodiment of the invention, the ink cartridge support structure also includes a motor, which is connected to the gravure roller 5 for transmission. The motor drives the gravure roller 5 to rotate. A control module is connected to the motor and is also used to adjust the motor speed. Based on the above configuration, the control module can coordinately control the motor speed and the output pressure of each cylinder 3, so that the stroke and output pressure of the cylinder 3 vary at different motor speeds, thereby matching the actual printing conditions and ensuring optimal working conditions. For example, when the motor speed is low, the output pressure of the cylinder 3 decreases; as the motor speed increases, the output pressure of the cylinder 3 increases accordingly, ensuring that the gravure roller 5 can be inked evenly at different speeds.

[0045] The above embodiments have described in detail an ink cartridge support structure of this utility model. Based on this ink cartridge support structure, it is possible to ensure uniform contact between the ink cartridge and the gravure roller, thereby ensuring uniform ink application on the gravure roller and guaranteeing the printing effect. In addition, the cylinder output pressure is flexibly adjustable and easy to operate. Furthermore, the ink cartridge and the gravure roller adopt a horizontal side-by-side design, which is aesthetically pleasing and provides a novel design style for current textile gravure printing machines.

[0046] This utility model also provides a gravure printing machine, including an ink cartridge support structure as described in any of the above embodiments.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical applications, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
