Description

Technical Field

[0001] This utility model relates to the field of trademark printing equipment technology, and in particular to a scraper pressing mechanism and trademark printing equipment. Background Technology

[0002] Screen printing refers to the process of creating a screen printing plate with images and text using a photosensitive method. Screen printing consists of five main elements: the screen printing plate, the squeegee, the ink, the printing table, and the substrate. It utilizes the basic principle that ink can pass through the mesh openings of the screen printing plate in the image areas, while ink cannot pass through the openings in the non-image areas. During printing, ink is poured into one end of the screen printing plate, and a squeegee applies pressure to the ink areas while moving at a constant speed towards the other end. As the squeegee moves, the ink is forced through the mesh openings in the image areas onto the substrate.

[0003] The existing invention patent application with publication number CN110789216A discloses a silk scarf printing device. Through the setting of a linkage mechanism, a positioning mechanism, and a conveying mechanism, the linkage mechanism drives the movable frame of the positioning mechanism to move up and down. When the printing frame presses down on the silk scarf, the scraper automatically scrapes and presses it. When the printing frame is lifted, the scraper lifts back to its original position. At the same time, the silk scarf is moved by the conveying mechanism, which reduces the labor intensity of workers and improves work efficiency.

[0004] However, the pressure between the squeegee and the printing plate in this printing device cannot be adjusted. When the equipment is used with materials of different hardness, it is necessary to adjust the pressure between the squeegee and the printing plate to effectively print clearly on materials with different hardness. Therefore, in view of these issues, there is an urgent need to develop a squeegee pressing mechanism and a trademark printing device to meet the needs of practical use. Utility Model Content

[0005] The purpose of this invention is to provide a scraper pressing mechanism and a trademark printing equipment to solve the above-mentioned defects.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] For this embodiment, please refer to Figures 1-3 The scraper 64 pressing mechanism 6, specifically implemented therein, includes a scraper 64, a first pressing cylinder 61, a crossbeam 63, and a swing arm 65. Both ends of the scraper 64 are movably connected to both ends of the crossbeam 63 through the swing arm 65. The crossbeam 63 and the first pressing cylinder 61 are movably connected through a connecting top plate 62 and a flexible connecting column 66. The output end of the first pressing cylinder 61 is fixedly connected to the middle of the connecting top plate 62. One end of the flexible connecting column 66 is fixedly connected to the connecting top plate 62, and the other end of the flexible connecting column 66 is movably connected to the crossbeam 63. The flexible connecting column 66 can move vertically in the middle of the crossbeam 63.

[0024] By using a swing arm 65 with its two ends movably connected to the crossbeam 63 and the scraper 64 respectively, the scraper 64 can be swung by the swing arm 65 when it just makes contact with the printing tray 42, thereby increasing the contact angle of the scraper 64 and avoiding the defect of uneven ink coverage. At the same time, the flexible connecting column 66 can adjust the contact pressure between the scraper 64 and the printing tray 42, so that the scraper 64 pressing mechanism 6 can adapt to materials with different hard surfaces and clearly print trademarks on the materials.

[0025] Specifically, such as Figure 2 and 3 As shown, the top of the flexible connecting column 66 is a threaded end 661, the bottom of the flexible connecting column 66 is a limiting end 64, and a spring 663 is sleeved in the middle of the flexible connecting column 66. The flexible connecting column 66 passes directly downward and upward through the limiting end 64 through the crossbeam 63 to form a limiting structure. The flexible connecting column 66 is threadedly connected to the connecting top plate 62 through the threaded end 661. The spring 663 is disposed between the crossbeam 63 and the connecting top plate 62. Rotating the flexible connecting column 66 can adjust the distance gap between the crossbeam 63 and the connecting top plate 62, thereby changing the compression stroke of the spring 663, so that the scraper 64 can obtain different pressures. This allows the scraper 64 pressing mechanism 6 to adapt to materials with different hard surfaces, enabling clear printing of trademarks on the materials.

[0026] Please see Figures 4-7 The trademark printing equipment specifically implemented therein includes a frame 1, a printing tray 42, a fixing fixture 2, and the aforementioned scraper 64 pressing mechanism 6. The fixing fixture 2 is located at the front end of the frame 1, and the frame 1 has an upwardly extending upright 3 in the middle. The printing tray 42 is located above the fixing fixture 2 via the tray pressing mechanism 4. The tray pressing mechanism 4 is movably located in the middle of the upright 3. The tray pressing mechanism 4 is located inside the tray pressing mechanism 4 via a horizontal drive mechanism 5.

[0027] Specifically, such as Figure 6 As shown, the pallet pressing mechanism 4 includes a support plate 41 and a second pressing cylinder 43. The edge of the support plate 41 is movably connected to the upright 3, and the second pressing cylinder 43 is fixedly connected to the top of the upright 3. The printing pallet 42 is fixedly connected to the front end of the support plate 41, and the horizontal drive mechanism 5 is located inside the support plate 41.

[0028] Specifically, such as Figure 5As shown, the horizontal drive mechanism 5 includes a sleeve 51, a mounting plate 52, and a horizontal drive cylinder 54. The sleeve 51 is a central structure and is horizontally fixedly connected to the inside of the bearing plate 41. The mounting plate 52 has guide posts 53 at both ends that match the sleeve 51. The guide posts 53 are movably sleeved inside the sleeve 51. The output end of the horizontal drive cylinder 54 is fixedly connected to one end face of the mounting plate 52, and the end face of the mounting plate 52 away from the horizontal drive cylinder 54 is fixedly connected to the first pressing cylinder 61.

[0029] Specifically, such as Figure 7 As shown, the machine frame 1 is also equipped with a finished product unloading mechanism 7. The finished product unloading mechanism 7 includes a fixed frame 71 and a third cylinder 73. The bottom of the fixed frame 71 is movably connected to the machine frame 1 through a guide rail slider assembly 74. The bottom end face of the fixed fixture 2 is provided with a downwardly protruding rotary joint 72. The fixed fixture 2 is movably connected to the top of the fixed frame 71 through the rotary joint 72. The bottom of the third cylinder 73 is rotatably connected to the bottom of the fixed frame 71. The output end of the third cylinder 73 is rotatably connected to one side of the fixed fixture 2.

[0030] The working process of a trademark printing equipment is as follows: The material is placed in the fixed fixture 2. The second pressing cylinder 43 drives the bearing plate 41 to move downward, so that the printing tray 42 contacts the surface of the material. Then, the first pressing cylinder 61 drives the connecting top plate 62 to move downward, so that the crossbeam 63 and the scraper 64 move vertically into the printing tray 42 at the same time. When the scraper 64 moves downward, the spring 663 between the crossbeam 63 and the connecting top plate 62 can apply appropriate pressure to the scraper 64. Finally, the horizontal driving cylinder 54 drives the mounting plate 52 to move horizontally. The scraper 64 pressing mechanism 6 can follow the mounting plate 52 to move horizontally, and the scraper 64 can be located in the printing tray 42 to scrape ink, thus completing the trademark printing.

[0031] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
