[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 5 As shown, a printmaking rubber roller that is easy to clean comprises a roller body 1 and a support frame 2. The support frame 2 is internally equipped with a rotatable roller body 1 through a hinge bolt 7. A connector 3 is welded and fixed on the outer side of the support frame 2. A handle 4 is bonded to the outer end of the connector 3. A cleaning liquid containing cavity 11 is provided inside the handle 4. A filling port 8 is provided on the end surface of the handle 4. A tail cover 5 is provided at the end of the handle 4. A stud 9 is fixed on the inner end surface of the tail cover 5. The stud 9 is screwed together with the filling port 8 through a thread. A guide tube 13 is provided inside the connector 3, and the right end of the guide tube 13 is connected to the cleaning liquid containing cavity 11. The left end of the guide tube 13 passes through the support frame 2 and is flush with its surface. A rubber plug 6 is sealed and connected to the outer end of the guide tube 13. This design solves the problems of the existing printmaking rubber roller itself having dead angles, being difficult and time-consuming to clean, the ink solution easily splashing during cleaning to cause pollution to clothes and desktops, and the cumbersome and repetitive cleaning process.

[0027] In this embodiment, the left and right end surfaces of the roller body 1 are connected to the circumferential surface with an arc surface structure, and the connection between the arc surface and the end surface is a stepped structure. The appearance of the arc surface causes the front end of the rubber roller to become wider. The cleaning efficiency should be improved under the premise of sacrificing the portability of the rubber roller. The width of the single-side arc surface is preferably 10 mm to 25 mm. The width of the single-side arc surface of the special model non-universal size rubber roller should be greater than 10% and less than 20% of the width of the overall roller. The design designs the left and right sides of the roller body 1 into an arc surface structure. Since the arc surface does not contact the screen, it is not easy to be stained with paint stains, which is easy to clean. It can minimize the dead corners and gaps in the coloring area, so that when cleaning, there will be no situation where the cleaning is not in place due to cleaning dead corners, and the cleaning process is time-consuming and labor-intensive. The arc surface structure is designed to be stepped to ensure the convenience and accuracy of the coloring operation, will not interfere with the coloring operation, and ensure the accuracy of plate making and coloring.

[0028] In this embodiment, the handle 4 is made of a transparent acrylic material, which is convenient for observing the liquid level change of the internal cleaning liquid, making the remaining amount of the cleaning liquid clear at a glance and convenient for timely replenishment. The handle 4 is set to an unconventional cylindrical structure with a narrow left end and a wide right end, which is ergonomic and more convenient to hold and more comfortable to hold than a conventional cylindrical curved surface.

[0029] In this embodiment, multiple groups of reinforcing ribs 12 are evenly arranged near the left end of the inner wall of the cleaning liquid holding cavity 11, and the multiple groups of reinforcing ribs 12 are an integrated structure with the handle 4. The multiple groups of reinforcing ribs 12 can support the handle 4 from the inside, significantly enhancing the structural strength and stability of the handle 4, which not only helps to resist external pressure and prevent the handle 4 from deforming or breaking during use, but also effectively disperses the pressure of the cleaning liquid on the inner wall of the cleaning liquid holding cavity 11, ensuring the integrity and sealing of the cleaning liquid holding cavity 11.

[0030] In this embodiment, the tail cover 5 is configured as a conical structure with a larger left end and a smaller right end, and the left end thereof is smoothly connected to the right end of the handle 4, and two groups of concave anti-skid grooves 10 are symmetrically provided on the annular surface of the tail cover 5. This design makes the connection between the tail cover 5 and the right end of the handle 4 more smoothly transitioned, and enhances the overall aesthetics. At the same time, the anti-skid grooves 10 provided can increase the friction between the hand and the tail cover 5. When opening or closing the tail cover 5, the fingers can be pressed tightly against the anti-skid grooves 10, which facilitates the fingers to rotate the tail cover 5, prevents the tail cover 5 from slipping in the user's hand, and facilitates the user to open and close the tail cover 5.

[0031] In this embodiment, the outer edge of the filling port 8 is chamfered to form an arc-shaped groove. The arc-shaped groove also helps to guide the cleaning liquid to flow smoothly into the filling port 8, reducing the splashing or dripping that may occur during the filling process, which not only makes the filling process more convenient and efficient, but also helps to keep the working environment clean and hygienic.

[0032] In this embodiment, an oleophobic plastic powder coating layer is provided on the inner wall of the guide tube 13. The inner wall of the guide tube 13 needs to be in contact with the oily solution for a long time. The oleophobic plastic powder coating layer can effectively reduce the adhesion and residue of the cleaning liquid on the inner wall of the guide tube 13, thereby ensuring the smooth flow of the cleaning liquid. At the same time, it can reduce the corrosion of the oily solution to the inner wall of the guide tube 13 and extend its service life.

[0033] The working principle of the printmaking rubber roller that is easy to clean is as follows: when in use, first place the used rubber roller properly, unscrew the tail cover 5, and inject the prepared ink cleaning liquid into the cleaning liquid holding cavity 11 through the filling port 8 at the tail end of the handle 4. At the same time, the groove on the filling port 8 can prevent the liquid from splashing, which helps to guide the cleaning liquid to flow smoothly into the filling port 8. Then tighten the tail cover 5, place the handle 4 vertically on the ground and place the roller body 1 on the lower side of the handle 4, and then open the rubber plug 6, so that the cleaning liquid in the cleaning liquid holding cavity 11 naturally flows down along the conduit and drips onto the surface of the roller body 1, soaking the roller body 1. Then, while keeping the handle 4 vertical, control the roller body 1 to roll back and forth on the coloring pad, so that the cleaning liquid completely covers and soaks the surface of the roller body 1, cleans the roller body 1, and can clean the coloring pad at the same time. Then, after adding an appropriate amount of cleaning liquid, re-cover the rubber plug 6 to close the guide tube 13 for next use. Use a scouring pad to wipe the part of the roller body 1 that needs to be cleaned, and wipe the side of the roller body 1 at the same time. You can use your thumb to stick the scouring pad to its curved side surface, and rotate the roller body 1 at the same time to maintain and improve the cleaning efficiency, without repeatedly wetting and wiping with cleaning liquid.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
