[0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc., are fabrics that do not require spinning or weaving. Screen printing is a wet printing method that prints graphics onto a flat surface and is a type of orifice printing. Screen printing uses the principle that the mesh holes in the graphic part of the screen printing plate can pass through the slurry, while the mesh holes in the rest of the screen are blocked and cannot pass through the slurry, forming a blank on the substrate, thereby achieving printing.

[0003] Currently, screen printing devices are used to print non-woven fabrics. These devices often require different patterns, and the screen often needs to be replaced to print different patterns. This requires a long downtime for the equipment to change screens, which affects the printing efficiency of the non-woven fabrics.

DETAILED DESCRIPTION

[0022] like Figures 1 to 7As shown, the utility model relates to an automatic screen printing device for non-woven fabrics, comprising a mounting platform 101 and a conveying mechanism 200 and a printing mechanism 300 provided on the mounting platform 101, and a screen changing mechanism 400 on the printing mechanism 300. The upper end of the mounting platform 101 is symmetrically mounted with a first support plate 102, and a roller 103 is rotatably mounted between the first support plates 102. The printing mechanism 300 comprises a mounting frame 301 rotatably mounted on the upper end of the mounting platform 101, a support rod 302 is installed on the upper end of the mounting frame 301, a first mounting plate 303 is installed at the end of the support rod 302, and the first mounting plate 303 is symmetrically mounted with a first support plate 102. 03 is rotatably mounted on the front end thereof with an adjustment plate 304 in contact with the roller 103. A second motor 305 driving the adjustment plate 304 is disposed at the rear end of the first mounting plate 303. A fixing plate 308 is mounted on the upper end of the mounting frame 301 on one side of the support rod 302. Positioning rods 309 are mounted between the fixing plates 308. Sliding blocks 310 are sleeved on the positioning rods 309. A sliding frame 311 is mounted between the sliding blocks 310. A scraper 312 is disposed at the lower end of the sliding frame 311. The screen changing mechanism 400 includes a second support plate 401, a second mounting plate 402, a storage cylinder 403, and a printing screen 405. The present invention can automatically perform screen printing on non-woven fabrics and facilitates the replacement of the printing screen 405, thereby effectively improving screen printing efficiency.

[0023] Specifically, a mounting groove is provided on one side of the upper end surface of the mounting platform 101. A driving wheel and a driven wheel are symmetrically mounted in the mounting groove. A conveyor belt 201 is provided between the driving wheel and the driven wheel. A first motor 202 is provided at the side end of the mounting platform 101 to drive the driving wheel. When the first motor 202 is turned on, the driving wheel rotates, thereby turning the conveyor belt 201 on to transport the non-woven fabric.

[0024] Furthermore, a first rotating rod 306 is fixedly mounted on the front end of the adjustment plate 304. A second rotating rod 307 is rotatably mounted on the distal end of the first rotating rod 306. The distal end of the second rotating rod 307 is rotatably connected to a sliding frame 311. The first rotating rod 306 is configured to pull the second rotating rod 307, which in turn pulls the sliding frame 311 to move, thereby moving the scraper 312 to scrape the ink for screen printing.

[0025] It is worth noting that the adjustment plate 304 includes a circular portion and a fan-shaped portion. The starting point of the first rotating rod 306 is located at the axis of the circular portion. The fan-shaped portion is arranged on the outside of the circular portion, and the corners of the fan-shaped portion are rounded. The arrangement of the circular portion and the fan-shaped portion of the adjustment plate 304 can complete the angle adjustment of the mounting frame 301 and the movement adjustment of the scraper 312. It can also raise the printing mechanism 300 when replacing the printing screen 405, making it easy to clearly see the adjusted position of the printing screen 405 and the pattern of the printing screen 405, preventing errors in the pattern of the printing screen 405 after adjustment and replacement, and ensuring the accuracy of the screen pattern when replacing the printing screen 405.

[0026] It is worth noting that the lower end surface of the mounting frame 301 is located below the scraper 312 and is fixed with a screen frame 313 via bolts. The lower end surface of the screen frame 313 is provided with a groove, and a rubber layer 314 is provided in the groove. The provision of the rubber layer 314 can prevent the printing screen 405 from being worn when the printing screen 405 is replaced, and can also facilitate the sealing between the printing screen 405 and the screen frame 313.

[0027] It is worth noting that the second support plate 401 is installed at the upper end of the mounting frame 301, and a second mounting plate 402 is installed at the end of the second support plate 401. A storage cylinder 403 is rotatably installed between the second mounting plates 402. Two storage cylinders 403 are provided, and the two storage cylinders 403 are symmetrically distributed. A printing screen 405 is rolled up on the storage cylinder 403, and the printing screen 405 contacts the rubber layer 314 through the lower end of the screen frame 313. The rotating shaft of the storage cylinder 403 extends to the side end of the second mounting plate 402 and a limiting buckle 404 is installed. The limiting buckle 404 includes a telescopic rod, which is installed at the end of the rotating shaft of the storage cylinder 403. A limiting plate is installed on the outer surface of the telescopic rod. The front end of the limiting plate is installed with a first tooth, and the side end of the second mounting plate 402 is installed with a second tooth corresponding to the first tooth. The first latching tooth is engaged with the second latching tooth to fix the storage tube 403 and prevent the storage tube 403 from rotating. Pulling the limit plate can make the first latching tooth disengage from the second latching tooth to loosen the fixation of the storage tube 403. Pressing the limit plate can make the telescopic rod extend and retract, so that the first latching tooth is re-engaged with the second latching tooth.

[0028] Working principle: This embodiment provides an automatic screen printing device for non-woven fabrics. When in use, the first motor 202 drives the conveyor belt 201 to work, and the non-woven fabric printing device is transported on the conveyor belt 201. The conveying stops when it is transported to the bottom of the printing mechanism 300, and the second motor 305 drives the adjustment plate 304 to rotate. During the rotation of the adjustment plate 304, the circular part contacts the roller 103 to adjust the angle of the mounting frame 301, so that the printing mechanism 300 in front of the mounting frame 301 can be lowered, so that the printing screen 405 contacts the non-woven fabric, and the adjustment plate 304 continues to rotate to make the circular part roll on the roller 103. The second rotating rod 307 can be pulled by the first rotating rod 306, so that the scraper 312 scrapes on the printing screen 405, so that the ink penetrates from the mesh to form a pattern on the non-woven fabric, and the adjustment plate 304 continues to rotate. During the process, when the fan-shaped part contacts the roller 103, the angle of the mounting bracket 301 can be adjusted again to make the printing mechanism 300 rise. At this time, the conveyor belt 201 continues to transport the printed non-woven fabric, and the unprinted non-woven fabric is located under the printing mechanism 300. When the fan-shaped part continues to rotate and contacts the roller 103, the scraper 312 can be returned to its original position. When the printing screen 405 needs to be replaced, the equipment stops working, and the limit plate is manually pulled to disengage the first tooth from between the second tooth. When it is manually rotated, the storage cylinder 403 rotates, so that the two storage cylinders 403 can be wound up and unwound one by one, so that the printing screens 405 with different patterns are located at the lower end of the screen frame 313. After adjustment, the two storage cylinders 403 are fixed by the limit buckle 404, and the replacement of the printing screen 405 can be completed, and the equipment can continue to work.
