[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A scraper device for a screen printing machine comprises two fixed plates, each of which has a groove on its upper end, each of which is slidably connected to a movable plate, each of which has a scraper fixedly connected to its upper end, each of which has a limiting slide groove on its inner wall, each of which has a buffer mechanism for buffering the scrapers on the same side, a movable mechanism for moving the two scrapers is arranged between the two fixed plates, and the movable mechanism comprises a power motor arranged between the two fixed plates, a drive rod is fixedly connected to the end of the output shaft of the power motor, and a gear is fixedly sleeved on the end of the drive rod.

[0007] Preferably, racks are fixedly connected to the side walls at opposite ends of the two fixing plates, and the racks on both sides are respectively meshed with the two sides of the gear.

[0008] Preferably, the buffer mechanism includes two symmetrically arranged limit sliding blocks slidably connected in the limit sliding groove, a movable plate is slidably connected in the groove, the lower ends of the two movable plates are fixedly connected to two symmetrically arranged fixed blocks, and the two fixed blocks are rotationally connected to the two limit sliding blocks through rotating rods respectively.

[0009] Preferably, the side walls of the two limiting sliding blocks are elastically connected to the inner wall of the limiting sliding groove via springs, and the two springs on the same side are symmetrically arranged.

[0010] Preferably, the two fixing plates are symmetrically arranged, and the two scrapers are also symmetrically arranged.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting up a moving mechanism, when in use, the output shaft of the driving power motor rotates, driving the driving rod and the gear to rotate, so that the rack meshing with it moves, so that the fixed plates and scrapers on both sides move, and the two scrapers are staggered and separated, and the scraper at the bottom scrapes to one side to complete the ink scraping. After completing one ink scraping, the moving mechanism is used to exchange the positions of the scrapers on both sides, and the ink scraping can be completed from the other side, which can greatly improve work efficiency.

[0013] 2. By setting up a buffer mechanism, the scraper will continue to rub against the screen printing plate, which is prone to wear. After a long time, the scraper cannot fit tightly. Under the action of the spring, the scraper and the screen printing plate fit tightly, which can greatly improve the ink scraping effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Reference Figure 1-4 A scraper device for a screen printing machine includes two fixed plates 1. A groove 3 is provided at the upper end of the two fixed plates 1. A movable plate 11 is slidably connected in the two grooves 3. A scraper 4 is fixedly connected to the upper end of the two movable plates 11. The two fixed plates 1 are symmetrically arranged, and the two scrapers 4 are also symmetrically arranged. It should be noted that the opposite sides of the scrapers 4 on both sides are inclined surfaces, which can better complete the scraping operation.

[0021] In this embodiment, limiting slots 5 are provided on the inner walls of the two grooves 3, and buffer mechanisms for buffering the scraper 4 on the same side are provided inside the two limiting slots 5. The buffer mechanism includes two symmetrically arranged limiting sliders 6 slidably connected in the limiting slots 5, and a movable plate 11 is slidably connected in the groove 3. The lower ends of the two movable plates 11 are fixedly connected with two symmetrically arranged fixed blocks 10, and the two fixed blocks 10 are rotatably connected to the two limiting sliders 6 respectively through rotating rods. The side walls of the two limiting sliders 6 are elastically connected to the inner walls of the limiting slots 5 through springs 7, and the two springs 7 on the same side are symmetrically arranged. It is worth mentioning that under the action of the buffer mechanism, the scraper 4 can be buffered. The screen printing plate and the scraper 4 are prone to wear due to long-term friction. Under the action of the spring 7, the scraper 4 can fit closely with the screen printing plate, which can improve the printing effect.

[0022] In this embodiment, a moving mechanism for moving the two scrapers 4 is arranged between the two fixed plates 1, and the moving mechanism includes a power motor 2 arranged between the two fixed plates 1, and the end of the output shaft of the power motor 2 is fixedly connected to a driving rod 8, and the end of the driving rod 8 is fixedly sleeved with a gear 9. Racks 12 are fixedly connected to the side walls at opposite ends of the two fixed plates 1, and the racks 12 on both sides are respectively meshed with the two sides of the gear 9. The gear 9 and the rack 12 are used to promote the staggered movement of the fixed plates 1 and the scrapers 4 on both sides.

[0023] When the utility model is used, the fixed plates 1 on both sides are installed on the printing machine. During the use of the machine, the output shaft of the power motor 2 is first driven to rotate, driving the driving rod 8 and the gear 9 to rotate. The rotation of the gear 9 can drive the racks 12 on both sides that are meshed with it to move, so that the fixed plates 1 on both sides and the scraper 4 move alternately, and the scraper 4 located below contacts the screen printing plate. Subsequently, the fixed plate 1 is moved to drive the scraper 4 to move, and ink scraping is completed.

[0024] After the ink scraping is completed, the output shaft of the driving power motor 2 is reversed, driving the driving rod 8 and the gear 9 to reverse, driving the racks 12 on both sides to move alternately, so that the fixed plates 1 on both sides and the scrapers 4 on both sides exchange positions, and the fixed plate 1 and the scraper 4 on the other side move down to contact the screen printing plate, and then move the fixed plate 1 and the scraper 4 in the opposite direction to complete the printing again. Printing can be continuously performed from both sides, greatly improving the processing efficiency of the device.
