Description

Technical Field

[0001] This utility model belongs to the field of printing machinery technology, and more specifically, it relates to a printing roller. Background Technology

[0002] Printing rollers are one of the core components of printing presses and have a wide range of applications. The surface of printing rollers is made with patterns and text information corresponding to the required printing content through processes such as engraving, etching, and laser imaging. Whether it is simple lines and letters or complex color images and exquisite patterns, they can be clearly presented. However, when commonly used printing rollers are worn or the printing content is changed during use, it is necessary to remake the plate, which increases the consumption of manpower and material resources. Therefore, a new type of printing roller is needed. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a printing plate roller, which solves the problem that existing printing plate rollers require remaking the plate when wear occurs or the printing content is changed, thus increasing the consumption of manpower and material resources.

[0004] This utility model relates to a printing roller, achieved through the following specific technical means:

[0005] A printing plate roller includes a support shaft, a movable baffle, and a cylinder;

[0006] The support shaft has a groove at its center end and round holes at both ends. The support shaft has four sets of threaded holes on the outer side of its left end. The roller is fitted onto the outer side of the support shaft. The roller has four sets of positioning holes one on its left end and four sets of positioning holes two on its right end. The movable baffle is fitted onto the outer side of the left end of the support shaft and has four sets of fixing bolts on the movable baffle, with the fixing bolts corresponding to the threaded holes.

[0007] Furthermore, the left and right ends of the support shaft are connected to limiters, and the left and right ends of the support shaft are provided with movable rods inside the circular holes, and springs are fitted on the movable rods, with the movable rods passing through the limiters.

[0008] Furthermore, a fixed baffle is fixedly connected to the outer side of the right end of the support shaft, and four sets of limiting rods A are fixedly connected to the left end of the fixed baffle, with the limiting rods A corresponding to the positioning holes.

[0009] Furthermore, four sets of limiting rods B are fixedly connected to the right side of the movable baffle, and the limiting rods B correspond to the positioning holes.

[0010] Furthermore, a rubber wheel is fixedly connected to the groove at the center end of the support shaft, and two sets of grooves are provided on the inner side of the roller, with an arc-shaped rubber plate fixedly connected in the two sets of grooves on the inner side of the roller.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model, by setting a movable baffle, facilitates the simple and quick installation and disassembly of the movable baffle by using four sets of fixing bolts on the movable baffle, with the fixing bolts corresponding to the threaded holes, making it convenient to replace the roller.

[0013] 2. This utility model uses a rubber wheel, which is fixedly connected to the groove at the center end of the support shaft. The friction between the rubber wheel and the arc-shaped rubber plate helps to maintain the stability of the relative position between the roller and the support shaft, preventing the roller from sliding randomly on the support shaft and ensuring the accuracy of printing.

[0014] 3. This utility model features a roller with four sets of positioning holes 1 on the left end and four sets of positioning holes 2 on the right end. Positioning holes 1 and 2 correspond to limiting rod B and limiting rod A, respectively. This design facilitates accurate installation of the roller on the support shaft during use, ensuring the roller's positional accuracy and thus improving the accuracy and stability of printing.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a printing plate roller, including a support shaft 1, a movable baffle 4, and a roller 6;

[0025] The support shaft 1 has a groove at its center end and round holes at both ends. The support shaft 1 has four sets of threaded holes 10 on the outer side of its left end. The roller 6 is fitted onto the outer side of the support shaft 1. The roller 6 has four sets of positioning holes 12 on its left end and four sets of positioning holes 23 on its right end. The movable baffle 4 is fitted onto the outer side of the left end of the support shaft 1 and has four sets of fixing bolts 5 on its movable baffle 4, with the fixing bolts 5 corresponding to the threaded holes 10.

[0026] Among them, such as Figure 1 and Figure 3 As shown, the left and right ends of the support shaft 1 are connected to limiting components 3. The left and right ends of the support shaft 1 are equipped with movable rods 2 inside the round holes, and springs 11 are fitted on the movable rods 2. The movable rods 2 pass through the limiting components 3. After the connection with the printing equipment is completed through the limiting components 3, its buffering and shock absorption mechanism will play a role. The movable rods are fitted with springs 11. During the working process of the printing plate roller, once it is subjected to axial impact force, the movable rod will move axially to a certain extent in the round holes at both ends of the support shaft. At this time, the springs 11 will be compressed or stretched according to the direction and magnitude of the impact force, thereby playing a role in buffering and shock absorption, protecting the overall structure of the printing plate roller, and extending its service life.

[0027] Among them, such as Figure 2 and Figure 4 As shown, a fixed baffle 7 is fixedly connected to the outer side of the right end of the support shaft 1. Four sets of limiting rods A9 are fixedly connected to the left end of the fixed baffle 7. The limiting rods A9 correspond to the positioning holes 13. Four sets of limiting rods B15 are fixedly connected to the right side of the movable baffle 4. The limiting rods B15 correspond to the positioning holes 12. The positioning holes 12 and 13 correspond to the limiting rods B15 and A9, respectively. During use, this facilitates the accurate installation of the roller 6 on the support shaft 1, ensuring the positional accuracy of the roller 6, thereby improving the accuracy and stability of printing.

[0028] Among them, such as Figure 3 and Figure 4 As shown, a rubber wheel 8 is fixedly connected in the groove at the center end of the support shaft 1. Two sets of grooves are provided on the inner side of the roller 6, and an arc-shaped rubber plate 14 is fixedly connected in the two sets of grooves on the inner side of the roller 6. The rubber wheel 8 can play a buffering and shock-absorbing role, reducing the impact of vibration on printing quality. The friction between the rubber wheel 8 and the arc-shaped rubber plate 14 helps to maintain the stability of the relative position of the roller 6 and the support shaft 1, preventing the roller 6 from sliding randomly on the support shaft 1.

[0029] The specific usage and function of this embodiment are as follows:

[0030] like Figures 1 to 4 As shown, in this utility model, the roller 6 is fitted onto the outside of the support shaft 1. The friction between the rubber wheel 8 and the arc-shaped rubber plate 14 helps to maintain the stability of the relative position between the roller 6 and the support shaft 1, preventing the roller 6 from sliding freely on the support shaft 1. The positioning holes 12 and 13 respectively cooperate with the limiting rods B15 and A9. During use, this facilitates the accurate installation of the roller 6 on the support shaft 1, ensuring the positional accuracy of the roller 6, thereby improving the accuracy and stability of printing.

[0031] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
