[0002] A screen printer is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics, thereby replicating a printed product identical to the printing plate.

[0003] After the screen printer completes printing, there will be ink adhesion on the screen printing workbench. The commonly used method is to wipe it manually with a cloth, but this method requires human intervention. Therefore, a cleaning process needs to be added during the screen printing process, resulting in frequent manual operations, a waste of time and effort, and a low degree of automation.

[0030] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] Please see attached Figure 1 The utility model is an ink cleaning mechanism, comprising a screen printing workbench 1, a sliding component 2 and a cleaning component 3, wherein the sliding component 2 drives the cleaning component 3 to slide on the surface of the screen printing workbench 1; wherein the cleaning component 3 comprises a support frame 31 connected to the sliding component 2, a cleaning member 32 and a first motor 33, wherein the first motor 33 is drivingly connected to the cleaning member 32 and is fixedly connected to one side of the support frame 31, one end of the cleaning member 32 is movably connected to the support frame 31, and the other end of the cleaning member 32 passes through the support frame 31 and is connected to the first motor 33.

[0034] The screen printing workbench 1 is used to place the substrate to be printed, such as a metal plate. The cleaning component 3 is used to clean the ink on the screen printing workbench 1. The sliding component 2 is used to drive the cleaning component 3 to move so as to wipe the screen printing workbench 1. When the cleaning component 32 finishes wiping, the first motor 33 rotates, driving the cleaning component 32 to rotate a certain angle,

[0035] Through the ink cleaning mechanism, its action process is as follows: after the screen printing is completed, the sliding component 2 is started to drive the cleaning member 32 to move toward the surface of the screen printing workbench 1, so that the cleaning member 32 wipes the screen printing workbench 1, thereby wiping the ink on the screen printing workbench 1 clean. After the wiping is completed, the first motor 33 is started to drive the cleaning member 32 to rotate a certain angle, so that the cleaning member 32 with stains is removed, and the clean cleaning member 32 is brought into contact with the screen printing workbench 1, and then the cleaning member 32 is moved to the initial position through the sliding component 2, which can effectively ensure the cleanliness of the wiping. Among them, each action of the ink cleaning mechanism can be realized by the existing PLC control.

[0036] Through the design of the cleaning mechanism, the cleaning component 3 and the sliding component 2 cooperate with each other, so that the cleaning member 32 moves on the surface of the screen printing workbench 1 through the sliding component 2 to wipe it, thereby replacing manual work. After each screen printing, there is a cleaning mechanism to clean and wipe the screen printing workbench 1, which reduces the frequency of manual operation, saves trouble, and correspondingly improves the degree of automation.

[0037] And by adopting the coordinated action of the first motor 33 and the cleaning member 32, when the cleaning member 32 wipes once, there will be stains at the corresponding position. After each wiping is completed, the first motor 33 will rotate a certain angle accordingly, so that the cleaning member 32 will move the stained position away, effectively realizing the continuity of cleaning.

[0038] Please see attached Figure 2 The cleaning member 32 includes a first rotating shaft 321, a cleaning roller 322, an adhesive layer 323 and an adhesive rag 324. The first rotating shaft 321 is drivingly connected to the first motor 33. The cleaning roller 322 passes through the first rotating shaft 321 and is fixedly connected to the first rotating shaft 321. The adhesive layer 323 is connected to the surface of the cleaning roller 322. The adhesive rag 324 is detachably connected to the adhesive layer 323. Specifically, the adhesive layer 323 can be Velcro. It is easy to replace the adhesive rag 324, and the operation is simple and convenient. In addition, the adhesive rag 324 can be a disposable adhesive rag 324.

[0039] When the cleaning member 32 moves and wipes on the screen printing workbench 1 through the sliding member 2, the first motor 33 does not move. After the cleaning member 32 finishes wiping, it stops on the screen printing workbench 1, and then the first motor 33 is started to drive the first rotating shaft 321 to drive the cleaning roller 322 to rotate a certain angle. After the cleaning roller 322 rotates until the clean sticky rag 324 contacts the screen printing workbench 1, the first motor 33 stops moving, and the sliding member 2 drives the cleaning member 32 back and forth to the initial position, thereby ensuring the cleanliness of wiping and preparing for the next cleaning. Among them, when the first motor 33 drives the cleaning roller 322 to rotate, the sticky rag 324 can further rotate and wipe the screen printing workbench 1 to improve the cleanliness of wiping. Effectively ensure the cleaning power of the cleaning member 32 on the screen printing workbench 1. In addition, when the sticky rag 324 is covered with stains, the sticky rag 324 can be directly torn off, and a new sticky rag 324 can be pasted with the adhesive layer 323, thereby completing the update of the rag, which is convenient to operate.

[0040] Specifically, the cleaning roller 322 is a cylindrical cleaning roller 322 , so that the first motor 33 can drive the cleaning roller 322 to rotate.

[0041] Please see attached Figure 3 The sliding component 2 includes a slide rail 21, a push cylinder 22 and a slider 23. The slide rail 21 is arranged on both sides of the screen printing workbench 1. The push cylinder 22 is fixedly connected to the slider 23 and drives the slider 23 to move on the slide rail 21. Preferably, two push cylinders 22 are provided. Through this setting, the operation process of the sliding component 2 driving the cleaning component 3 is: start the push cylinder 22, push the slider 23 to move on the slide rail 21, so that the cleaning component 3 moves back and forth on the screen printing workbench 1. The cleaning component 3 can be set to move back and forth 1-3 times on the screen printing workbench 1, which can be flexibly set according to the specific situation. Ensure the normal operation of the cleaning component 3.

[0042] Embodiment 2:

[0043] The difference between this embodiment and embodiment 1 is that, see Figure 4-Figure 5 , the cleaning roller 322 is a polyhedral cylindrical cleaning roller 322. The cleaning component 3 also includes a lifting cylinder 34, which is connected between the sliding component 2 and the support frame 31. Through this setting, when the cleaning roller 322 is set as a polyhedral cylinder, one side of the cleaning roller 322 is in contact with the screen printing workbench 1, which correspondingly increases the contact area between the two and improves the cleaning strength. However, for the polyhedral cylindrical cleaning roller 322, before the cleaning roller 322 needs to be rotated, the lifting cylinder 34 needs to be started, so that the cleaning component 3 rises to a certain height, and then the cleaning roller 322 is rotated to another clean surface, and then the lifting cylinder 34 drives the cleaning component 3 to descend, so that the clean surface of the cleaning roller 322 is in contact with the screen printing workbench 1, and then the cleaning roller 322 is brought back to the initial position through the sliding component 2. Through this setting, the contact area between the rag and the screen printing workbench 1 is effectively increased, thereby improving the cleaning ability. And by setting the lifting cylinder 34, the smoothness of the rotation of the cleaning roller 322 can be ensured to avoid collision. Among them, the operation process of the lifting cylinder 34 and other components can be realized by the existing PLC program control.

[0044] Embodiment 3:

[0045] The difference between this embodiment and embodiment 1 is that, see Figure 6-7 The cleaning component 3 further includes an ink scraper 35 and a second motor 36. The ink scraper 35 is arranged in parallel with the cleaning component 32 and is arranged close to one side of the screen printing workbench 1. The second motor 36 is drivingly connected to the ink scraper 35 and is fixedly connected to one side of the support frame 31. One end of the ink scraper 35 is movably connected to the support frame 31, and the other end of the ink scraper 35 passes through the support frame 31 and is connected to the second motor 36. The ink scraper 35 includes a second rotating shaft 351 and a scraper 352. The second rotating shaft 351 is drivingly connected to the second motor 36, and the scraper 352 is fixedly connected to the middle position of the second rotating shaft 351.

[0046] In this embodiment, when the screen printing machine is just started, or when the ink becomes dry, the second motor 36 can be started to drive the second rotating shaft 351 to rotate, so that the scraper 352 is downwardly contacted with the screen printing workbench 1, and then when the sliding component 2 drives the cleaning component 3 to move, the ink scraping member 35 scrapes the screen printing workbench 1 in front of the movement, and the cleaning member 32 located at the rear of the movement wipes the screen printing workbench 1. When the sliding component 2 drives the cleaning component 3 to reset, the second motor 36 drives the second rotating shaft 351 to rotate, so that the scraper 352 is not in contact with the screen printing workbench 1. At the same time, the cleaning roller 322 is driven by the first motor 33 to rotate a certain angle, and then the cleaning component 3 is reset through the sliding component 2. Among them, the ink scraping member 35 and the second motor 36 are started by a manual button, and the operation process of the ink scraping member 35, the second motor 36 and other components can be realized by the existing PLC program control. Effectively improve the cleaning ability, can handle and clean inks in different states, and the cleaning force is correspondingly strengthened.
