[0028] First embodiment

[0029] Please refer to Figures 1-4 As shown, a flat screen printing machine for clothing fabrics includes a body 1, a conveyor belt 2 and a scraping device 3. The conveyor belt 2 is installed on the body 1 and is driven by a motor for conveying fabrics;

[0030] A sieve mesh 4, which is fixedly installed on the scraping device 3 for supporting dyes;

[0031] The scraping device 3 includes a first scraper 5 and a second scraper 6. Both the first scraper 5 and the second scraper 6 are controlled by a motor to slide back and forth on the surface of the sieve mesh 4;

[0032] The surface of the body 1 is fixedly connected with a feeding box 8. The surface of the feeding box 8 is provided with a material distribution box 9. A plurality of discharge holes are opened on the surface of the material distribution box 9. The surface of the material distribution box 9 is rotatably connected with a baffle 12 through a hinge. An elastic sheet 17 is arranged between the material distribution box 9 and the baffle 12;

[0033] A switch mechanism is provided on the surface of the material distribution box 9, and the switch mechanism includes a support rod 14, a horizontal axis 19 is fixedly connected to the surface of the support rod 14, and a squeeze plate 11 is rotatably connected to the surface of the horizontal axis 19 through a torsion spring, and a plug 22 is fixedly connected to the surface of the baffle 12, and the plug 22 is truncated and made of rubber. The squeeze plate 11 is approximately "L" shaped, and the long arm end of the squeeze plate 11 contacts the baffle 12, and the short arm end of the squeeze plate 11 contacts the scraper 5;

[0034] During operation, the dye is first poured into the loading box 8, and then the cloth to be dyed is placed on the surface of the conveyor belt 2, and the conveyor belt 2 is turned on. At this time, the conveyor belt 2 drives the cloth to move under the screen 4, and then, driven by the motor, drives the printing mechanism to move downward, and at the same time drives the screen 4 to fit the surface of the cloth. At this time, the motor controls the scraper 1 5 and the scraper 2 6 to be misaligned with each other, and controls the scraper 2 6 to fit the surface of the screen 4. Then, when the scraper 2 6 moves toward the loading box 8, the dye is printed on the surface of the cloth. When the scraper 2 6 moves to the extreme position, the scraper 1 5 will first squeeze the squeezing plate 11, so that the squeezing plate 11 rotates around the horizontal axis 19, and at the same time squeezes the torsion spring to generate elastic force. At this time, the long arm end of the squeezing plate 11 will fit the surface of the baffle 12, and the baffle 12 is moved to make the baffle The plate 12 moves around the hinge, and the plug 22 on the surface of the baffle 12 will be separated from the discharge port on the surface of the powder box. At this time, the dye in the distribution box 9 will fall between the scraper 1 5 and the scraper 2 6. At this time, the motor drives the scraper 2 6 to lift up and the scraper 1 5 to drop, so that the scraper 1 5 fits on the surface of the screen 4. While the scraper 1 5 fits on the screen 4, it will be separated from the short arm end of the squeezing plate 11. At this time, the spring piece 17 will drive the baffle 12 to reset, and the rubber plug 22 will be re-inserted into the discharge port, and the distribution box 9 will be closed to prevent excess dye from leaking out. Through the design of the baffle 12 and the squeezing plate 11, the scraper 1 5 can be used to add the dye in a timely and quantitative manner to avoid the inaccuracy of manual addition, avoid excess dye overflow, and prevent drying, and also ensure the cleanliness of the workbench.

[0035] A connecting plate 16 is provided between the feeding box 8 and the distributing box 9. The feeding box 8, the connecting plate 16 and the distributing box 9 are all designed to be interconnected. A rubber sheet 15 is fixedly connected to the surface of the connecting plate 16. A quantitative mechanism is provided on the surface of the distributing box 9. The quantitative mechanism includes an inclined rod 23. The surface of the inclined rod 23 is slidably connected to a push rod 7 through a spring. One end of the push rod 7 is in contact with the scraper 5. The end of the push rod 7 away from the scraper 5 is slidably connected to a top plate 26 through a spring. The top plate 26 is used to squeeze and close the rubber sheet 15. A main magnetic block 21 is fixedly connected to the surface of the push rod 7. A sliding rod 24 is slidably connected to the surface of the inclined rod 23 through a spring. A secondary magnetic block 25 is fixedly connected to the end of the sliding rod 24. The main magnetic block 21 and the secondary magnetic block 25 are attracted out of phase with each other.

[0036] During operation, before the second scraper 6 moves to the extreme position, the first scraper 5 will first squeeze the ejector rod 7, causing the ejector rod 7 to slide on the surface of the inclined rod 23 and simultaneously squeezing the spring to generate elastic force. At this time, the ejector rod 7 will drive the top plate 26 to move, making the top plate 26 fit on the surface of the rubber sheet 15. Then the first scraper 5 continues to move, causing the top plate 26 to squeeze the rubber sheet 15. Since the connecting plate 16 is arranged between the material distribution box 9 and the feeding box 8 and is in a communicating state, and the three sides of the connecting plate 16 are made of soft material, the squeezed rubber sheet 15 will close the material discharge hole in the middle of the connecting plate 16, thus preventing the dye from continuously being conveyed into the material distribution box 9. When the first scraper 5 is about to move to the extreme position and squeeze the extrusion plate 11, the ejector rod 7 will contract into the top plate 26, thus avoiding jamming. While the ejector rod 7 contracts into the top plate 26, it will drive the main magnet 21 to move. When the main magnet 21 moves below the secondary magnet 25, due to the principle of opposite-phase attraction, the secondary magnet 25 will move towards the direction of the main magnet 21 and drive the slide rod 24 to move at the same time. When the main magnet 21 passes through the secondary magnet 25, the spring drives the slide rod 24 to reset, causing the slide rod 24 to strike the material distribution box 9, so that the dye in the material distribution box 9 can completely fall.
