Description

Technical Field

[0001] This utility model relates to the field of ink roller technology, specifically to an ink roller assembly for a cardboard printing machine. Background Technology

[0002] Currently, a printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, impression, and paper feeding (including folding). Its working principle is as follows: first, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the printing press to the areas on the printing plate containing the text and images, and then directly or indirectly transferred to paper or other substrates such as textiles, cardboard, plastics, and leather, thus reproducing a printed product identical to the printing plate. The inking roller assembly is the transfer device for applying ink. The inking roller is an essential structure for the operation of a printing press.

[0003] Utility model patent CN218343073U discloses an ink roller assembly for a cardboard printing machine. It solves the problem that ink roller assemblies for cardboard printing machines are typically fixedly connected and require dynamic connection to the transfer bearing, making maintenance or replacement extremely difficult and necessitating disassembly of the printing machine. The patent employs a locking ball groove on the outer diameter surface of a limiting sleeve, with the grooves evenly spaced around the circumferential surface of the limiting sleeve. The locking ball groove engages with a self-locking ball in a self-locking structure. When the limiting sleeve is inserted into the inner diameter surface of the ink roller adapter, the self-locking ball engages with the inner diameter surface of the locking ball groove, thus limiting the ink roller's disengagement. However, the aforementioned patent uses a locking structure combining a locking ball groove and a self-locking ball, which makes the device difficult to manufacture and complex, significantly increasing production and maintenance costs, and consequently leading to poor practicality. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide an ink roller assembly for a cardboard printing machine, which has the advantages of simple structure and ease of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ink roller assembly for a cardboard printing machine, comprising an ink roller body, a printing plate sleeve fitted on the surface of the ink roller body, an ink roller adapter on the left side of the ink roller body, an installation groove on the right side of the ink roller adapter, and an installation block slidably connected inside the installation groove, the installation block being fixedly connected to the ink roller body, a slot on the top of the installation block, a receiving groove on the top of the ink roller adapter, a locking frame slidably connected inside the receiving groove, the locking frame being inserted into the slot, the receiving groove communicating with the installation groove, a tension spring fixedly connected to the inner wall of the receiving groove, the other end of the tension spring being fixedly connected to the locking frame, and a limit component on the surface of the ink roller adapter.

[0006] In a preferred embodiment of this invention, the limiting component includes two sliding grooves disposed on the surface of the ink roller adapter, and a slider is slidably connected inside the sliding groove. A limiting frame is slidably connected to the surface of the ink roller adapter, and the limiting frame is fixedly connected to the slider.

[0007] As a preferred embodiment of this utility model, a fixing ring is fixedly connected to the surface of the ink roller adapter, a compression spring is fixedly connected to the right side of the fixing ring, the other end of the compression spring is fixedly connected to the limiting frame, and the surfaces of the tension spring and the compression spring are both coated with anti-rust paint.

[0008] As a preferred embodiment of this utility model, a handle is fixedly connected to the top of the locking frame, the handle is fitted with the limiting frame, and the surface of the handle is provided with anti-slip texture, and the number of anti-slip textures is several.

[0009] As a preferred embodiment of this utility model, the top of the limiting frame is fixedly connected with two levers, which are evenly distributed on the top of the limiting frame.

[0010] As a preferred embodiment of this utility model, the surface of the ink roller adapter is fixedly connected to a mounting ring, and the surface of the mounting ring is provided with mounting openings. The number of mounting openings is several, and the mounting openings are evenly distributed in a ring on the surface of the mounting ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model employs a plate sleeve fitted onto the surface of the ink roller body and a sliding connection structure between the ink roller adapter and the ink roller body, along with a locking frame and slot locking mechanism, significantly improving the maintenance convenience of the ink roller assembly. Traditional ink roller assemblies are mostly fixed connections, requiring disassembly of the entire printing press for replacement or maintenance, which is time-consuming and labor-intensive. In this design, however, the ink roller body can be easily separated from the ink roller adapter simply by releasing the locking frame using the limiting component and then pulling up the locking frame, without the need for complex tools or operations. This modular design greatly shortens maintenance time, reduces downtime costs, and improves production efficiency. Furthermore, the sliding fit structure between the mounting block and the mounting slot not only ensures connection stability but also effectively reduces wear during installation, extending the service life of the ink roller assembly. This device boasts the advantages of simple structure and ease of use.

[0013] 2. This utility model provides a reliable limiting function for the locking frame through the cooperation of the sliding groove, the sliding block, and the limiting frame. When the locking frame is inserted into the slot to lock the ink roller body and the ink roller adapter, the limiting frame can slide to the top of the locking frame to prevent the locking frame from disengaging from the slot due to vibration or accidental collision, ensuring the stability and reliability of the connection. Compared with the traditional single locking method, this double locking structure greatly improves the safety of the ink roller assembly during high-speed operation. At the same time, the sliding cooperation design of the sliding block and the sliding groove makes the movement of the limiting frame smoother and the operation more convenient. In addition, the setting of the limiting component can also effectively prevent dust, ink and other contaminants from entering the locking structure, reducing the probability of failure caused by contamination, and further improving the stability and service life of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4As shown, an ink roller assembly for a cardboard printing machine includes an ink roller body 1, a printing plate sleeve 2 fitted on the surface of the ink roller body 1, an ink roller adapter 3 on the left side of the ink roller body 1, an installation groove on the right side of the ink roller adapter 3, and an installation block 4 slidably connected inside the installation groove. The installation block 4 is fixedly connected to the ink roller body 1, and a slot is provided on the top of the installation block 4. A receiving groove is provided on the top of the ink roller adapter 3, and a locking frame 5 is slidably connected inside the receiving groove. The locking frame 5 is inserted into the slot, and the receiving groove communicates with the installation groove. A tension spring 6 is fixedly connected to the inner wall of the receiving groove, and the other end of the tension spring 6 is fixedly connected to the locking frame 5. A limit component 7 is provided on the surface of the ink roller adapter 3.

[0021] refer to Figure 2 The limiting component 7 includes two sliding grooves on the surface of the ink roller adapter 3, and a slider is slidably connected inside the sliding groove. A limiting frame 9 is slidably connected to the surface of the ink roller adapter 3, and the limiting frame 9 is fixedly connected to the slider.

[0022] As a technical optimization of this utility model, the locking frame 5 is reliably limited by the cooperation of the sliding groove, the slider, and the limiting frame 9. When the locking frame 5 is inserted into the slot to lock the ink roller body 1 and the ink roller adapter 3, the limiting frame 9 can slide to the top of the locking frame 5, preventing the locking frame 5 from dislodging from the slot due to vibration or accidental collision, thus ensuring the stability and reliability of the connection. Compared with the traditional single locking method, this double locking structure greatly improves the safety of the ink roller assembly during high-speed operation. At the same time, the sliding cooperation design of the slider and the sliding groove makes the movement of the limiting frame 9 smoother and the operation more convenient. In addition, the setting of the limiting component 7 can also effectively prevent dust, ink and other contaminants from entering the locking structure, reducing the probability of failure caused by contamination, and further improving the stability and service life of the equipment.

[0023] refer to Figure 1 A fixing ring 8 is fixedly connected to the surface of the ink roller adapter 3. A compression spring 10 is fixedly connected to the right side of the fixing ring 8. The other end of the compression spring 10 is fixedly connected to the limit frame 9. The surfaces of the tension spring 6 and the compression spring 10 are both coated with anti-rust paint.

[0024] As a technical optimization of this utility model, the performance of the limiting component 7 is further optimized by setting a fixing ring 8 and a compression spring 10 on the surface of the ink roller adapter 3, and spraying anti-rust paint on the surfaces of the tension spring 6 and the compression spring 10. The elastic effect of the compression spring 10 ensures that the limiting frame 9 always maintains pressure on the locking frame 5, ensuring that the locking frame 5 will not loosen during long-term use. Even when the equipment vibrates or is subjected to external impact, the compression spring 10 can absorb energy through its own deformation, maintaining the stable position of the limiting frame 9. The anti-rust paint on the surfaces of the tension spring 6 and the compression spring 10 effectively improves the corrosion resistance of the springs and extends their service life. In the working environment of a paperboard printing machine, ink, moisture, etc., can easily corrode metal parts, and the application of anti-rust paint can significantly reduce this risk, ensuring the elastic performance and working stability of the springs. This design not only reduces the frequency of spring replacement and lowers maintenance costs, but also improves the reliability and stability of the equipment.

[0025] refer to Figure 2 A handle 12 is fixedly connected to the top of the locking frame 5. The handle 12 fits against the limiting frame 9. The surface of the handle 12 is provided with anti-slip texture, and the number of anti-slip textures is several.

[0026] As a technical optimization of this utility model, by providing a handle 12 with anti-slip texture on the top of the locking frame 5, and by providing a lever 11 on the top of the limiting frame 9, the ease of operation is greatly improved. The handle 12 is designed according to ergonomic principles, making it convenient for operators to grip and apply pulling force, easily realizing the insertion and removal operation of the locking frame 5. The anti-slip texture increases the friction between the hand and the handle 12, effectively preventing slippage even when ink is smudged, ensuring the safety and reliability of operation.

[0027] refer to Figure 1 Two levers 11 are fixedly connected to the top of the limiting frame 9, and the levers 11 are evenly distributed on the top of the limiting frame 9.

[0028] As a technical optimization of this utility model, two levers 11 are evenly arranged on the top of the limiting frame 9, further optimizing the operating experience. The design of the two levers 11 allows operators to choose a more comfortable and convenient way to move the limiting frame 9 according to their operating habits and actual conditions. In situations with limited space, operators can move the limiting frame 9 by moving the levers 11 in different positions, avoiding operational difficulties caused by insufficient operating space. Furthermore, the even distribution of the levers 11 allows for more uniform force application by the operator, reducing the likelihood of jamming or shifting during the movement of the limiting frame 9, and improving the stability and accuracy of the operation. This design fully considers various situations in actual operation, providing operators with a more convenient and efficient operating method.

[0029] refer to Figure 1 The surface of the ink roller adapter 3 is fixedly connected to a mounting ring 13. The surface of the mounting ring 13 is provided with mounting openings 14. There are several mounting openings 14, which are evenly distributed in a ring on the surface of the mounting ring 13.

[0030] As a technical optimization of this utility model, by setting an installation ring 13 and opening multiple installation ports 14 on the surface of the ink roller adapter 3, the ink roller adapter 3 can be fixedly connected to the transfer shaft of the printing machine by bolts. The transfer shaft of the printing machine can drive the ink roller adapter 3 to rotate, thereby driving the installation block 4, the ink roller body 1 and the printing plate sleeve 2 to rotate. The ink roller body 1 and the printing plate sleeve 2 mentioned above are similar in principle to the ink roller and printing plate sleeve 2 mentioned in the utility model patent disclosed in CN218343073U, which discloses an ink roller assembly for a cardboard printing machine, and achieve the same effect. This application will not elaborate further.

[0031] The working principle and usage process of this utility model are as follows: When using the ink roller assembly of this paperboard printing machine, the first step is to prepare for installation. Next, connect the ink roller body 1 to the ink roller adapter 3. Place the ink roller adapter 3 in a suitable position, aligning the mounting groove with the mounting block 4 on the left side of the ink roller body 1. Slowly push the ink roller body 1, allowing the mounting block 4 to slide into the mounting groove until it is fully inserted. During this process, care must be taken to maintain the coaxiality of the ink roller body 1 and the ink roller adapter 3 to avoid collisions or jamming between the mounting block 4 and the mounting groove.

[0032] Then, the locking operation is performed. After the mounting block 4 is fully inserted into the mounting slot, the operator releases the locking bracket 5. The locking bracket 5 will automatically slide into the slot under the action of the tension spring 6, achieving initial locking of the mounting block 4. At this time, the operator releases the limiting bracket 9. Under the action of the compression spring 10, the limiting bracket 9 slides to the right, so that the handle 12 at the top of the locking bracket 5 should be in contact with the limiting bracket 9. This prevents the locking bracket 5 from moving upward and prevents it from dislodging from the slot due to vibration or accidental collision, thus completing the double locking.

[0033] Next, the components are installed on the printing press. Using the multiple mounting holes 14 on the mounting ring 13 of the ink roller adapter 3, bolts are used to securely connect the ink roller adapter 3 to the transfer shaft of the printing press. Ensure that the bolts are tightened firmly to ensure that the transfer shaft of the printing press can effectively drive the ink roller adapter 3 to rotate, thereby driving the ink roller body 1 and the printing plate sleeve 2 to rotate synchronously.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
