Description

Technical Field

[0001] The utility model relates to the technical field of silk screen printing, in particular to an oil return scraper device. Background Art

[0002] Silk screen printing is the most adaptable and widely used printing method in the world. The silk screen is used as the base, and a silk screen disc with a pattern is made through the photosensitive plate making method. The printed clothing is placed on the printing table, and the ink is transferred to the clothing through the silk screen printing plate using a scraper to form a pattern. For multi-color printing, a printing plate must be made for each ink color, and each color is applied separately in a separate layer.

[0003] When ink is applied to the screen printing plate and the clothing is printed through the through holes on the screen printing plate, the ink will seep down along the small holes and then print on the surface of the material. During the scraping process, the ink will accumulate in the direction of the scraper (similar to scraping cream), resulting in ink accumulation in the front, that is, the accumulated ink is scraped to one side, which will cause too much ink to be used on one side of the pattern during screen printing, resulting in the pattern being too dark.

[0021] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0022] Please refer to Figure 1-Figure 3 The utility model proposes an oil return scraper device, including a support seat 1, a hydraulic lifting seat 2 is slidably arranged on the support seat 1, a lateral moving mechanism 3 is arranged on one side of the hydraulic lifting seat 2, the lateral moving mechanism 3 includes a lateral guide rail 31, the lateral guide rail 31 is fixed on one side of the hydraulic lifting seat 2, the lateral guide rail 31 is slidably connected to the lateral moving seat 32, the lateral moving seat 32 is provided with a lifting mechanism 4, the lifting mechanism 4 includes a fixed seat 41, the fixed seat 41 is fixed on the lateral moving seat 32, the fixed seat 41 is slidably connected to the first lifting rod 42, the lower end of the first lifting rod 42 is installed with a scraper 43, a screen printing plate 5 is installed on the hydraulic lifting seat 2, and the screen printing plate 5 is installed on the hydraulic lifting seat 2. The disk 5 is located below the scraper 43, and an oil receiving assembly is provided on one side of the scraper 43. The surface of the screen printing disk 5 is provided with an infiltration hole, and the ink is coated on the surface of the screen printing disk 5. The hydraulic lifting seat 2 descends on the support seat 1 and approaches the material below the screen printing disk 5. Before this, the first lifting rod 42 pushes the scraper 43 to descend and contact the surface of the screen printing disk 5. The transverse moving seat 32 moves transversely on the transverse guide rail 31. At this time, the scraper 43 scrapes on the screen printing disk 5, scrapes the ink on the surface of the screen printing disk 5, and flattens the ink, thereby improving the screen printing effect of the screen printing disk 5 on the material. The hydraulic lifting seat 2, the transverse moving seat 32, and the first lifting rod 42 are all driven by a hydraulic cylinder.

[0023] In this embodiment, the oil receiving assembly includes a second lifting rod 6, which is slidably connected to the fixed seat 41, and the lower end of the second lifting rod 6 is fixedly connected to the clamping member 7, and a shielding plate 8 is installed at the lower end of the clamping member 7. One side of the shielding plate 8 is fixedly connected to the supporting plate 9. When the transverse moving seat 32 moves transversely on the transverse guide rail 31, when the scraper 43 scrapes on the screen printing plate 5, when the ink on the surface of the screen printing plate 5 is scraped flat, the excess ink will be pushed in the moving direction until the scraper reaches the other side of the screen printing plate 5. The excess ink gathers on the other side of the screen printing plate 5. When screen printing, it will cause too much pattern ink on one side, which will cause the pattern here to be darker and uneven in depth from other parts of the pattern. At this time, by setting the shielding plate 8, the shielding plate 8 is located on one side of the scraper 43. When the excess pattern is scraped to the other side of the screen printing plate 5, part of the ink overflows to the supporting plate 9 on the side of the shielding plate 8, thereby reducing the amount of ink accumulated on the screen printing plate 5.

[0024] The scraper 43 is mounted on the movable clamping assembly 11, and the rotating rod 10 is rotatably connected to the movable clamping assembly 11. The rotating rod 10 is rotatably connected to the movable clamping assembly 11, and the outer side of the rotating rod 10 is rotatably connected to the two support plates 12, and the round rod 13 is rotatably connected between the two support plates 12. The first lifting rod 42 is hinged on one side of the cylinder 14, and the telescopic rod of the cylinder 14 is fixedly connected to the round rod 13. When the transverse moving seat 32 moves transversely on the transverse guide rail 31, the cylinder 14 pushes the round rod 13, so that the movable clamping assembly 11 drives the scraper 43 to swing back and forth. The rotation direction of the scraper 43 is to rotate toward the inner side of the baffle plate 8 to scrape the ink, and the ink will be scraped to the inner side of the baffle plate 8, and the ink will be connected with the scraper 43, so that the accumulated ink will not stay on the silk screen disk 5, avoiding the situation of darker patterns.

[0025] In this embodiment, the movable clamping assembly 11 includes a fixed block 111, which is rotatably connected to the rotating rod 10. A clamp 112 is provided below the fixed block 111. The clamp 112 is used to clamp the scraper 43. A square groove is provided on the upper surface of the clamp 112, which cooperates with the fixed block 111. Clamping protrusions 113 are provided on both sides of the clamp 112. Two clamping rings 114 are placed on the fixed block 111. The clamping ring 114 is provided with a placement groove for fitting the fixed block 111. The side wall of the placement groove is provided with a clamping groove 115. The clamping groove 115 cooperates with the clamping protrusion 113 of the clamp 112. The clamp 112 The scraper 43 is clamped, and the raised part of the clamp 112 is clamped in the groove 115 on the clamping ring 114. Since the scraper 43 has an arc trajectory when it swings, the distance between it and the screen printing plate 5 is changing. In order to keep the bottom of the scraper 43 always in contact with the screen printing plate 5, when the scraper 43 swings, the scraper 43 and the clamp 112 slide in the groove 115 on the clamping ring 114, which can change the distance between the bottom of the scraper 43 and the fixed block 111, and adapt to the change in the distance from the fixed block 111 to the bottom of the scraper 43 when the scraper 43 swings, so that when the scraper 43 swings, the bottom of the scraper 43 always contacts the screen printing plate 5, and the ink on the surface of the screen printing plate 5 is scraped.

[0026] In this embodiment, a mounting groove is provided at the lower end of the clamp 112, and the mounting groove is used to place the scraper 43. A through hole is provided on the side wall of the clamp 112, and the through hole is connected to the mounting groove. The scraper 43 is placed in the mounting groove, and a threaded rod 15 and a fastening nut are installed in the through hole. The mounting groove is squeezed to squeeze and fix the scraper 43, which is convenient for installation and disassembly.

[0027] In this embodiment, the two clamping rings 114 are both threadedly connected to the threaded rod 15, and the threaded rod 15 passes through the clamping ring 114 and is threadedly connected to the clamping ring 114. The threaded rod 15 is rotated, and the sliding range of the clamp 112 and the scraper 43 is controlled by the distance between the lower end of the threaded rod 15 and the fixed block 111. This sliding range can be adjusted according to the rotation amplitude of the scraper 43.

[0028] In this embodiment, the upper ends of the threaded rods 15 are fixedly connected to the control blocks 16 to facilitate the rotation of the threaded rods 15 .

[0029] In this embodiment, a threaded hole is provided on the upper surface of the fixing block 111 near the two ends of the fixing block 111, and the threaded holes are connected to the limit rods 17. The clamping ring 114 is located between the two limit rods 17. The lower end of the clamping ring 114 is clamped by the clamp 112, and the two sides are blocked by the limit rods 17 to prevent the clamping ring 114 from falling off.

[0030] Working principle: ink is coated on the surface of the screen printing plate 5, and the hydraulic lifting seat 2 descends on the support seat 1 and approaches the material under the screen printing plate 5. Before this, the first lifting rod 42 pushes the scraper 43 to descend and contact the surface of the screen printing plate 5. The transverse moving seat 32 moves transversely on the transverse guide rail 31, and the cylinder 14 pushes the round rod 13, so that the movable clamping assembly 11 drives the scraper 43 to swing back and forth. The rotation direction of the scraper 43 is toward the inner side of the baffle plate 8 to rotate and scrape the ink. The ink will be scraped to the inner side of the baffle plate 8 and connected with the scraper 43, so that the accumulated ink will not stay on the screen printing plate 5.

[0031] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
