Description

Technical Field

[0001] This application relates to the technical field of printing roller cleaning, and particularly relates to a printing roller cleaning device. Background Art

[0002] Printing technology is a technology for copying graphic and text information. Printed matter is an information carrier for spreading scientific and cultural knowledge. Printed matter is a carrier of characters and images, a tool for information transmission and a medium for cultural dissemination. It is the spiritual food and material basis of people's daily life and has become an indispensable part of human life. A printing press generally consists of mechanisms such as plate loading, inking, printing, and paper feeding. Its working principle is as follows: First, the characters and images to be printed are made into printing plates and installed on the printing press. Then, ink is applied to the areas with characters and images on the printing plate by manual or the printing press, and then directly or indirectly transferred to paper or other printing substrates, thereby replicating the same printed matter as the printing plate. Printing rollers are indispensable in the printing process. If the printing roller is not clean during ink coating and is mixed with other inks, it will inevitably cause color deviation and also result in dull colors. After the printing roller is used for a period of time, it needs to be cleaned to remove the stains on its surface to ensure that there will be no color deviation during its next use.

Detailed Description of the Invention

[0014] The following will further describe the present application in detail Figures 1-3 with reference to the attached drawings.

[0015] The embodiment of the present application discloses a printing roller cleaning device. Refer to Figures 1-3, including a water tank 1, a return frame 2, a printing roller body 5 and a slider 31. Grooves are formed at both ends of the top of the water tank 1. Both ends of the printing roller body 5 are respectively movably inserted into the two grooves, so that the printing roller body 5 is supported on the inner top of the water tank 1. The return frame 2 is installed above the water tank 1 through a support member 4. The support member 4 is composed of a return block 41 and a support block 42. The return block 41 is fixedly connected to one side of the water tank 1. One end of the support block 42 is fixedly connected to one end of the return frame 2. The bottom end of the support block 42 is movably inserted into the return block 41. The inner top wall of the support block 42 contacts one end of the top of the water tank 1, so that the return frame 2 can be supported above the printing roller body 5. The top end of the slider 31 slides inside the return frame 2. Two sides of the slider 31 are respectively attached to two inner side walls of the return frame 2. A driving member 6 for driving the slider 31 to slide is arranged at one end of the return frame 2. The driving member 6 is composed of a forward and reverse motor 61 and a one-way threaded rod 62. The forward and reverse motor 61 is fixedly installed on one side of the support block 42. The forward and reverse motor 61 is electrically connected to an external power supply through an external switch. The power shaft of the forward and reverse motor 61 rotates through the support block 42 and the return frame 2. The one-way threaded rod 62 is threaded through the slider 31. One end of the one-way threaded rod 62 is fixedly connected to the end of the power shaft of the forward and reverse motor 61. The other end of the one-way threaded rod 62 rotates through one inner side wall of the return frame 2. The power shaft of the forward and reverse motor 61 drives the one-way threaded rod 62 to rotate. During the rotation of the one-way threaded rod 62, a spiral thrust is applied to the slider 31, which can drive the slider 31 to move. The bottom end of the slider 31 is fixedly connected with a water collecting ring 32. A plurality of water permeable holes are formed in the inner side wall of the water collecting ring 32. A sealing ring 33 is fixedly connected to one side of the water collecting ring 32. A sponge ring 34 is fixedly connected to the inner side wall of the sealing ring 33. Both the water collecting ring 32 and the sponge ring 34 are movably sleeved on the outer surface of one end of the printing roller body 5. One side of the water collecting ring 32 is fixedly penetrated with a connector 35. One end of the connector 35 is fixedly sleeved with a hose 36. The hose 36 is communicated with the drainage port of an external water pump. When the water collecting ring 32 is sleeved on the outer surface of the printing roller body 5, and at the same time, the printing roller body 5 and the return frame 2 are moved, so that both ends of the printing roller body 5 are inserted into the two grooves, and at the same time, the support block 42 at one end of the return frame 2 is inserted into the return block 41. Then, the power shaft of the forward and reverse motor 61 drives the one-way threaded rod 62 to rotate. During the rotation of the one-way threaded rod 62, a spiral thrust is applied to the slider 31, which can push the slider 31 to move. The slider 31 drives the water collecting ring 32, the sealing ring 33 and the sponge ring 34 to move. During the movement of the water collecting ring 32, the external water pump injects water into the water collecting ring 32 through the hose 36 and the connector 35. The water in the water collecting ring 32 is sprayed out through a plurality of water holes onto the outer surface of the printing roller body 5 for cleaning. At the same time, the sponge ring 34 slides on the outer surface of the printing roller body 5 to wipe it, and the dust attached to the outer surface of the printing roller body 5 can be cleaned up.

[0016] Reference Figure 1 and Figure 2 At the middle part of the top end of the loop-shaped frame 2, a handle 7 is fixedly connected. Holding the handle 7 facilitates the movement of the loop-shaped frame 2. At the bottom end of one side of the water tank 1, a drain pipe 8 is fixedly penetrated. Through the drain pipe 8, the water in the water tank 1 can be discharged.

[0017] The implementation principle of a printing roller cleaning device according to an embodiment of the present application is as follows: When in use, first penetrate one end of the printing roller body 5 through the water collecting ring 32 and the sponge ring 34. Then hold the loop-shaped frame 2 and the printing roller body 5 to move, so that the two ends of the printing roller body 5 are respectively movably inserted into the two grooves, and at the same time, the support block 42 at one end of the loop-shaped frame 2 is inserted into the inside of the loop-shaped block 41. Then, use the external switch to start the forward and reverse motor 61. The forward and reverse motor 61 is preferably of the type TCH(V)22 - 100 - 140CB. The power shaft of the forward and reverse motor 61 drives the one-way threaded rod 62 to rotate. During the rotation of the one-way threaded rod 62, a spiral thrust will be applied to the slider 31, which can push the slider 31 to move. The slider 31 drives the water collecting ring 32, the sealing ring 33 and the sponge ring 34 to move. During the movement of the water collecting ring 32, an external water pump injects water into the water collecting ring 32 through the hose 36 and the connector 35. The water in the water collecting ring 32 is sprayed out through several water holes onto the outer surface of the printing roller body 5 for cleaning. At the same time, the sponge ring 34 slides on the outer surface of the printing roller body 5 to wipe it, and the stains attached to the outer surface of the printing roller body 5 can be cleaned up.
