Description

Technical Field

[0001] The utility model relates to the technical field of printing screens, and particularly relates to a printing screen which is convenient for quick cleaning. Background Art

[0002] A printing screen is a core component in the screen printing process, which consists of a strong screen frame and a screen (mostly made of synthetic fibers) tightly stretched thereon. As a medium for image transfer, the densely distributed mesh holes on the screen allow the ink to pass through, thereby forming patterns or characters on the printing substrate.

[0003] After the printing screen is used, it needs to be cleaned in time. Prepare cleaning agents such as anhydrous ethanol, banana water or thinners. First, evenly apply the cleaning agent on the screen, especially on the image part. Gently wipe it with a sponge or soft cloth to ensure that the mesh holes are not damaged. For the area with an image, first scrape it to the edge and then conduct a detailed cleaning. When cleaning, the screen should be placed flat to avoid changes in the screen tension caused by vertical cleaning. After cleaning, rinse the screen with clean water to ensure that there is no residue of the cleaning agent and prevent the generation of bubbles.

[0004] The deficiencies of the existing technical solutions are as follows: During the process of cleaning the printing screen, the techniques and forces of each operator vary significantly. If the force is too light, it is often difficult to completely remove the dirt and residues on the screen, resulting in low cleaning efficiency. If the force is too heavy, it may directly threaten the delicate patterns and lines on the screen. After multiple cleanings, it is easy to cause irreversible damage to the printing screen, thus making it difficult to ensure the cleaning efficiency and effect. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a printing screen which is convenient for quick cleaning, so as to solve the technical problem that in the process of cleaning the printing screen in the prior art, the techniques and forces of each operator vary significantly, thus making it difficult to ensure the cleaning efficiency and effect.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figure 1 - Figure 2As shown in the figure, a printing screen plate that is convenient for quick cleaning includes a screen frame 1. A screen printing mesh 2 is fixedly arranged inside the screen frame 1. The device further includes a cleaning mechanism 7 for cleaning the screen printing mesh 2. The cleaning mechanism 7 includes a scraper 701 for scraping off thick oil stains, a sponge 705 for moistening and wiping the screen printing mesh 2, and a brush plate 704 for cleaning the inner wall of the mesh holes. The bottom of the scraper 701 includes a soft brush, and the soft brush can extend into the mesh holes to play a role in dredging and cleaning. The scraper 701 and the brush plate 704 are arranged in parallel. Guide plates 706 that are parallel to each other are fixedly connected to both sides of the scraper 701 and the brush plate 704. The guide plates 706 connect the scraper 701 and the brush plate 704 together. The sponge 705 is arranged in cooperation between the scraper 701 and the brush plate 704. The scraper 701 and the brush plate 704 limit the sponge 705 by extrusion, which is convenient for replacing the sponge 705. Guide grooves 5 that cooperate with the guide plates 706 are arranged on the inner walls of both sides of the screen frame 1. The guide grooves 5 are responsible for guiding and limiting the cleaning mechanism 7, so as to ensure that the scraper 701, the sponge 705, and the brush plate 704 move along the middle straight line of the screen frame 1. An oil stain recovery assembly that cooperates with the scraper 701 is arranged at one end of the screen frame 1. Through other tools, the oil stains can be scraped into the oil stain recovery assembly to realize the collection of the oil stains.

[0023] In some specific implementation schemes, in order to facilitate the collection of oil stains, a scraper 703 is fixedly connected to the lower end of the scraper 701. The scraper 703 can be used to scrape off the thick oil stains sticking to the screen printing mesh 2. A material storage groove 702 for storing oil stains is opened at the lower end of the scraper 701. The inner wall of the material storage groove 702 is arranged as an arc-shaped groove wall along the upper edge of the scraper 703, so that the oil stains scraped off by the scraper 703 can enter the interior of the material storage groove 702 along the upper edge of the scraper 703 to realize the collection of the oil stains.

[0024] In some specific implementation schemes, in order to facilitate the recovery of oil stains, the oil stain recovery assembly includes a wedge-shaped slope block 3 fixedly arranged on one side inside the screen frame 1, and a collection channel 4 that cooperates with the wedge-shaped slope block 3 is opened on the screen frame 1. When the scraper 701 scrapes the thick oil stains on the screen printing mesh 2 to one side of the wedge-shaped slope block 3, the oil stains in the material storage groove 702 can be scraped onto the wedge-shaped slope block 3 through a scraping tool and pushed into the collection channel 4 along the wedge-shaped slope block 3, so as to facilitate the recovery of the oil stains.

[0025] In some specific embodiments, to facilitate the pushing of the scraping plate 701, the sponge 705, and the brushing plate 704, a gripping mechanism 6 is cooperatively provided at the upper ends of the scraping plate 701, the sponge 705, and the brushing plate 704. The gripping mechanism 6 includes a U-shaped top plate 601. Limit strips 707 are fixedly connected to the sides of the scraping plate 701 and the brushing plate 704 away from the sponge 705. Limit grooves 603 that cooperate with the limit strips 707 are formed on both sides of the bottom of the U-shaped top plate 601. When installing the U-shaped top plate 601, align the limit grooves 603 with the limit strips 707, and push the U-shaped top plate 601 so that the limit grooves 603 slide along the limit strips 707 until the limit strips 707 completely enter the interior of the limit grooves 603, thereby completing the connection between the gripping mechanism 6 and the cleaning mechanism 7. A push plate 602 is fixedly connected to the U-shaped top plate 601. Workers can push the U-shaped top plate 601 to move through the push plate 602, thereby pushing the scraping plate 701, the sponge 705, and the brushing plate 704 to move along the guide groove 5.

[0026] In some specific embodiments, to facilitate the disassembly of the cleaning mechanism 7, a disassembly notch 8 that communicates with the guide groove 5 and is slidably engaged with the guide plate 706 is formed at one end of the mesh frame 1 away from the collection channel 4. After the cleaning of this set of silk screen meshes 2 is completed, the push plate 602 can be pushed towards the disassembly notch 8 to align the guide plate 706 with the disassembly notch 8. Then, pull up the push plate 602. The push plate 602 drives the U-shaped top plate 601, the scraping plate 701, the sponge 705, and the brushing plate 704 to move upward. At this time, the guide plate 706 is slidably connected to the disassembly notch 8 until the guide plate 706 disengages from the disassembly notch 8, thereby completing the disassembly of the cleaning mechanism 7, which facilitates the cleaning of another set of silk screen meshes 2 through the cleaning mechanism 7 or facilitates the workers to clean the scraping plate 701, the sponge 705, and the brushing plate 704.

[0027] To facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be described in combination with a specific application scenario:

[0028] When installing the U-shaped top plate 601, the limit groove 603 can be aligned with the limit strip 707, and the U-shaped top plate 601 is pushed so that the limit groove 603 slides along the limit strip 707 until the limit strip 707 completely enters the inside of the limit groove 603, thus completing the connection between the gripping mechanism 6 and the cleaning mechanism 7. When it is necessary to clean the silk screen mesh 2, the screen frame 1 needs to be placed on a plane to ensure that the silk screen mesh 2 is flush with the plane. The guide plate 706 on the cleaning mechanism 7 is placed into the guide groove 5 along the disassembly notch 8, and the push plate 602 is pushed along the guide groove 5 to move, thereby driving the scraper 701, the sponge 705, and the brush plate 704 to move along the guide groove 5. The movement of the scraper 701 drives the scraper knife 703 to scrape the thicker oil stains on the silk screen mesh 2. The oil stains scraped off by the scraper knife 703 can enter the inside of the material storage groove 702 along the upper edge of the scraper knife 703 to achieve the collection of the oil stains. When the scraper 701 scrapes the thicker oil stains on the silk screen mesh 2 to one side of the wedge-shaped slope block 3 along the guide groove 5, the oil stains inside the material storage groove 702 can be scraped onto the wedge-shaped slope block 3 by a scraping tool and pushed into the collection channel 4 along the wedge-shaped slope block 3, thus facilitating the recovery of the oil stains, reducing the waste of resources, and due to the limiting effect of the guide groove 5, the pressure of the scraper 701, the sponge 705, and the brush plate 704 on the silk screen mesh 2 is fixed, which can effectively prevent the silk screen mesh 2 from physically deforming due to uneven pressure;

[0029] After the oil stains on the collection channel 4 are recovered, cleaning liquid is poured into the screen frame 1 to clean the remaining oil stains. The push plate 602 is repeatedly pushed, and the push plate 602 drives the scraper 701, the sponge 705, and the brush plate 704 to clean the silk screen mesh 2. Among them, the soft brush on the brush plate 704 can penetrate into the mesh holes of the silk screen mesh 2 to remove the tiny particles and oil stains attached to the inner wall of the mesh holes. The sponge 705 mainly plays the role of wetting and wiping, so as to effectively remove the oil stains and impurities. The scraper knife 703 on the scraper 701 scrapes the oil stains cleaned from the silk screen mesh 2, so as to achieve the rapid cleaning of the remaining oil stains;

[0030] After the cleaning of this group of silk screen meshes 2 is completed, the push plate 602 can be pushed towards the disassembly notch 8 so that the guide plate 706 is aligned with the disassembly notch 8, and then the push plate 602 is pulled up. The push plate 602 drives the U-shaped top plate 601, the scraper 701, the sponge 705, and the brush plate 704 to move upward. At this time, the guide plate 706 is slidably connected to the disassembly notch 8 until the guide plate 706 disengages from the disassembly notch 8, that is, the disassembly of the cleaning mechanism 7 is completed, thus facilitating the cleaning of another group of silk screen meshes 2 through the cleaning mechanism 7, or facilitating the staff to clean the scraper 701, the sponge 705, and the brush plate 704.

[0031] The above has described in detail an embodiment of the present utility model, but the above content is only a preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
