Description

Technical Field

[0001] This utility model relates to the field of screen printing equipment for curtain fabrics, and in particular to a quick color-changing structure for multi-color curtain textile printing. Background Technology

[0002] To print color overlays on curtain fabric, screen printing equipment is needed. The screen is pressed onto the curtain fabric, and then the ink on the top surface of the screen is scraped by a squeegee, allowing the ink to adhere to the curtain fabric. By continuously switching screen frames, different inks and patterns are applied to the curtain fabric to complete the overlay printing.

[0003] In existing curtain fabric printing equipment, multiple screens are arranged side by side. As the curtain fabric is conveyed, it passes through each screen in turn for printing. The screen frames that fix the screens are fixed on the lifting structure. As a result, when the pattern of the curtain fabric is adjusted, it is necessary to disassemble and assemble multiple screen frames one by one in order to change the pattern. This is a cumbersome operation. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a quick color-changing structure for multi-color curtain textile printing that allows for rapid frame replacement.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A quick color-changing structure for multi-color curtain textile printing includes a curtain fabric conveyor frame. A base is provided on one side of the curtain fabric conveyor frame. A lifting frame is fixed in the middle of the inner wall of the bottom of the base. A prism-shaped switching shaft is rotatably connected to the top surface of the lifting frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 6 This embodiment provides a quick color-changing structure for multi-color curtain textile printing, including a curtain fabric conveyor 1, a base 2 on one side of the curtain fabric conveyor 1, a lifting frame 3 fixed in the middle of the bottom inner wall of the base 2, and a prism-shaped switching shaft 4 rotatably connected to the top surface of the lifting frame 3, with the upper end of the switching shaft 4 passing through the top surface of the base 2 and extending above the base 2.

[0024] A worm gear 5 is fixed on the outer wall of the switching shaft 4. A worm 6 is rotatably connected to the top surface of the lifting plate 302 through a bearing. The worm 6 is meshed with the worm gear 5. A motor 7 is fixed on the top surface of the lifting plate 302. The end of the worm 6 is fixed to the output end of the motor 7.

[0025] A cross 8 is fixed to the top of the switching shaft 4. L-shaped mounting strips 9 are fixed to the four ends of the cross 8. A mesh frame 10 is slidably inserted into the inner wall of the mounting strip 9. A groove 11 is opened on the inner wall of the mounting strip 9 near the switching shaft 4. The groove 11 is arranged horizontally. A slide rail 12 is fixed on the outer wall of the mesh frame 10 near the switching shaft 4. The slide rail 12 is slidably inserted into the inner side of the groove 11.

[0026] One of the mounting strips 9 is located directly above the curtain fabric conveyor 1, and a linear motor 137 is fixed on the outer wall of the mounting strip 9. A crossbar 14 is fixed to the moving end of the linear motor 137, and a rubber scraper 15 is fixed on the outer wall of the crossbar 14. The lower end of the rubber scraper 15 extends to the inner side of the mesh frame 10.

[0027] After the curtain fabric is delivered to the position, the lifting frame 3 is retracted, which allows the mounting strip 9 facing the curtain fabric conveying frame 1 to descend, so that the screen frame 10 is attached to the curtain fabric. Then, the linear motor 137 drives the rubber scraper 15 to scrape the ink on the inner surface of the screen frame 10 for printing. Then, the lifting frame 3 rises, and the motor 7 drives the worm gear 6 to rotate, which in turn drives the worm wheel 5 to rotate, causing the switching shaft 4 to rotate 90 degrees, switching a screen frame 10 to the top of the curtain fabric conveying frame 1. Then, the printing work continues, and screen frames 10 of different colors and patterns are continuously switched to the top of the curtain fabric conveying frame 1.

[0028] The lifting frame 3 includes four telescopic rods 301 symmetrically fixed at the middle position of the bottom inner wall of the base 2. The extended ends of the four telescopic rods 301 are fixed with lifting plates 302. The switching shaft 4 is rotatably connected to the middle of the lifting plate 302 through bearings. An electric push rod 303 is fixed at the middle of the bottom inner wall of the base 2. The extended end of the electric push rod 303 is fixed to the bottom surface of the lifting plate 302. The mesh frame 10 is driven to rise and fall. The lifting plate 302 can be raised and lowered by driving the electric push rod 303 to extend and retract.

[0029] A sleeve 16 is slidably fitted on the outer wall of the upper end of the switching shaft 4. Four connecting strips 17 are symmetrically fixed on the outer wall of the sleeve 16. Each connecting strip 17 corresponds to a mesh frame 10. The end of the connecting strip 17 near the mesh frame 10 is slidably connected to a pin 18 through a sliding hole. Both ends of the pin 18 have annular protrusions. The top surface of the pin 18 is inclined. A slot 19 is opened on the bottom surface of the mesh frame 10 opposite the pin 18. The top of the pin 18 is engaged in the slot 19. A spring 20 is fitted on the outer side of the upper end of the pin 18. One end of the spring 20 is pressed against the outer wall of an annular protrusion at the upper end. The other end of the spring 20 is pressed against the top surface of the connecting strip 17. A threaded hole is opened on the side wall of the sleeve 16. A bolt 21 is threadedly connected in the threaded hole. One end of the bolt 21 abuts against the outer wall of the switching shaft 4. A knob 22 is fixed on the end of the bolt 21 away from the switching shaft 4.

[0030] When inserting the wire frame 10 into the mounting strip 9, align the slide rail 12 with the slide groove 11, and then insert the slide rail 12 into the slide groove 11 continuously. During the insertion process, the outer wall of the wire frame 10 will abut against the inclined surface of the pin 18, forcing the inclined surface to slide downward to compress the spring 20 to store force until the wire frame 10 is inserted and installed in place. At this time, the pin 18 is facing the slot 19. Then the spring 20 rebounds and pushes the pin 18 into the slot 19, completing the positioning of the wire frame 10.

[0031] When the pattern of the printed curtain fabric changes, the knob 22 is turned so that the bolt 21 moves away from the switching shaft 4, allowing the sleeve 16 to slide downwards. This allows multiple pins 18 to be pulled out of the slots 19 simultaneously, thus unlocking the four frames 10 at the same time without having to unlock them sequentially. The frames 10 can then be pulled out. After all four frames 10 have been pulled out, the sleeve 16 can be pushed up to reset it. Then, the knob 22 is turned so that the end of the bolt 21 abuts against the outer wall of the switching shaft 4, where it can be engaged by the pins 18 during the subsequent insertion of the frames 10.

[0032] On the outer wall of the switching shaft 4, there are limit protrusions fixed at both ends of the sleeve 16. When the pin 18 is in the position of engaging the mesh frame 10, the top of the sleeve 16 abuts against a limit protrusion at the upper end. After the knob 22 is turned to unlock the sleeve 16, the sleeve 16 is lowered and slides down to a limit protrusion at the lower end.

[0033] In summary, this utility model significantly reduces the number of assembly and disassembly steps for the mesh frame 10 by sliding and inserting it onto the mounting strip 9 and positioning the mesh frame 10 on the mounting strip 9 through a snap-fit ​​mechanism. This is significantly different from traditional fixing methods such as bolts 21 or welding. By mounting the connecting strip 17 of the connecting pin 18 together on a sleeve 16, when disassembling the mesh frame 10, it is only necessary to move the sleeve 16 downwards to unlock all four snap-fit ​​structures simultaneously, thus unlocking all four mesh frames 10 at the same time. This eliminates the need for sequential operation, further saving steps and making it more convenient to use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
