[0002] A printing machine is a widely used piece of equipment in industries such as textiles, clothing, home furnishings, and advertising. It is mainly used to print patterns, text, or logos on the surface of various materials. An oval printing machine is a type of printing machine whose core feature is its printing platform designed with elliptical (or circular) guide rails, distinguishing it from traditional flat or roller-type structures.

[0003] The printing plate (also known as the printing platform or worktable) of a printing machine is mainly used to fix the substrate (such as fabric, paper, plastic, etc.) to ensure that it remains flat and stable during the printing process, so as to achieve accurate alignment and high-quality printing.

[0004] Most existing printing machines use fixed, non-removable printing plates, limiting their application. A large printing plate is used to print large fabric pieces, a pattern-making machine to print finished garments, and so on, making it impossible to use one machine for multiple purposes. While some printing machines allow for plate replacement, the process is cumbersome. It requires disassembling screws, reassembling, and leveling, among other things, which is very troublesome, time-consuming, and labor-intensive. Utility Model Content

[0051] Reference Figures 1-14 A quick-change device for a printing machine printing table includes a printing arm 1 and a table 2 mounted on the printing arm 1. The printing arm 1 is mounted on the body of the printing machine 3. Multiple support adjustment devices 4 are installed on both sides of the printing arm 1 along the length direction to support the table 2 and adjust the height and level of the table 2. The support adjustment devices 4 shown in the figure are six in total, three on each side, and arranged symmetrically in pairs.

[0052] The printing arm 1 is equipped with a cover plate 5, both of which are detachable for easy replacement and maintenance. Two positioning plates 6 are installed side by side along the length of the bottom of the cover plate 5, and a spring 7 connects the two positioning plates 6 to keep them taut. Two first arc-shaped grooves 8 are symmetrically opened at both ends of each positioning plate 6. The two first arc-shaped grooves 8 on one positioning plate 6 are reversed and mirrored with the two first arc-shaped grooves 8 on the other positioning plate 6, but the specifications and shapes of each arc-shaped groove are the same. A first connecting member 9 is inserted into the first arc-shaped groove 8 of each positioning plate 6. The first connecting member 9 can be used to limit the positioning plate 7 to move along the arc-shaped groove 8. Each positioning plate 6 is movably connected to the cover plate 5 through the first connecting member 9. Multiple positioning grooves 10 are opened on both sides of the cover plate 5, a total of six in the figure, three on each side, symmetrically arranged in pairs.

[0053] A handle is mounted on the top of the cover plate 5 between the two positioning plates 6 via a connecting shaft 11; two second arc-shaped grooves 12 are correspondingly opened on the cover plate 5 between the two positioning plates 6, and a second connecting piece 13 is correspondingly placed in each second arc-shaped groove 12. The second connecting piece 13 can move along the second arc-shaped groove 12, and one end of the second connecting piece 13 is connected to the handle 14. The two second arc-shaped grooves 12 and the two second connecting pieces 13 are symmetrically arranged with the connecting shaft as the center. The first connecting piece 9 and the second connecting piece 13 can be pins or shafts, etc.

[0054] Multiple limiting plates 15 are arranged side by side along the length of the bottom of the table plate 2. Three plates are shown in the figure. Each limiting plate 15 has a hook 151 symmetrically arranged at both ends of its bottom. The angle between the hook 151 and the limiting plate 15 is an acute angle. The hook 151 can be used to clamp or release the clamping plate 6 and the cover plate 5. The two ends of the limiting plate 15 are placed on the support adjustment device 4 located on both sides of the printing arm 1. Each hook 151 is inserted into the clamping groove 10 on both sides of the cover plate 5. The clamping groove 10 is a rectangular or square through groove that passes through the cover plate 5. A V-shaped notch 10a is opened on each clamping groove 10 on one side to facilitate the hook 151 to enter or exit the clamping groove 10.

[0055] When using, first adjust the height of each support adjustment device 4 so that the support surface of each support adjustment device 4 is on the same horizontal plane, thereby ensuring the levelness of the platform 2 when it is placed flat on it; each support adjustment device 4 only needs to be adjusted once, and there is no need to adjust it again when replacing the platform 2, which is convenient and quick.

[0056] When installing the platform 2, first turn the handle 14. The two second connectors 13 slide along the two second arc grooves 12 in an arc. The two second connectors 13 push the two locking plates 6 to move in opposite directions, one to the left and the other to the right. The spring 7 between the two locking plates 6 will be stretched and elongated. During this process, due to the restriction of the first connector 9, the two locking plates 6 can only slide along the first arc groove 8 in an arc. As a result, the area of ​​the two locking plates 6 that blocks the locking groove 10 on one side gradually decreases, and finally there is enough space for the hooks 151 to be inserted. Then, the hooks 151 of the platform 2 are inserted into the corresponding locking grooves 10, and the bottom surface of the platform 2 is placed flat on the support surface of each support adjustment device 4.

[0057] By rotating the handle 14 in the opposite direction or releasing the handle 14, under the action of the spring 7, the two locking plates 6 simultaneously slide back to their initial state along the first arc groove 8, so that one side of the two locking plates 6 abuts against the hook 151. The hook 151 hooks the two locking plates 6 and keeps them tight under the action of the spring 7, so that the table plate 2 is connected and fixed to the printing arm 1. If you want to replace the table plate 2 with a different specification, you can use the same method as when installing the table plate 2, remove the original table plate 2 and then install the new table plate 2.

[0058] This application allows for the prior adjustment of the height and level of each support adjustment device 4, thereby ensuring the height and level of the table plate 2. Only one adjustment is needed, and no further adjustment is required when replacing the table plate 2, making it convenient and quick. The table plate 2 is easy to install, replace, and disassemble, facilitating the replacement of table plates 2 of different specifications. This enables one printing machine 3 to process a variety of products of different specifications, achieving multi-purpose functionality and solving the problems of existing factories needing to equip multiple models, resulting in large investments, large footprints, and low utilization rates.

[0059] In some embodiments, the support adjustment device 4 includes a support base 400 connected to the printing arm 1, a threaded connector 401 threadedly connected to the support base 400, and a support block 402 mounted on the top of the threaded connector 401. The top of the support block 402 is flat, and the bottom planes of both ends of the limiting plate 15 are placed flat on the support block 402. The threaded connector 401 can be a bolt or a threaded rod. The support base 400 can be L-shaped or T-shaped, etc., and the support block 402 can be cylindrical or square, etc. The support block 402 is used to support the platform 2. By rotating the threaded connector 401, the support block 402 can be raised or lowered, thereby adjusting the height and level of the platform 2. The above structure is simple, low in cost, and easy to use.

[0060] In some embodiments, the support block 402 is threadedly connected to the screw connector 401 for easy installation and disassembly. Both ends of the connection between the screw connector 401 and the support base 400 are provided with a washer 403 and a nut 404. The washer 403 can be used to prevent loosening and to buffer vibration, while the nut 404 can further limit and lock the screw connector 401 to prevent it from loosening and to ensure that the height and level of the platform 2 remain constant.

[0061] In some embodiments, each limiting plate 15 is U-shaped, and each limiting plate 15 has a limiting groove 150 at its bottom, which is a U-shaped groove. The support block 402 extends into the limiting groove 150, which can limit the movement range of the support block 402 and prevent it from falling off. The hook 151 is located at the bottom of the limiting plate 15 on both sides of the limiting groove 150 to avoid blocking the support block.

[0062] In some embodiments, the handle 14 includes a circular plate 140 placed parallel to the top of the cover plate 5, an extension plate 141 located on one side of the plate 140, which extends to the outside of one side of the cover plate 5 for easy operation, and a push-pull plate 142 is vertically provided at the end of the extension plate 141 for easy pushing and pulling by hand to control the handle 14 to rotate forward or backward.

[0063] In some embodiments, the printing arm 1 and the cover plate 5 are U-shaped to reduce weight. The cover plate 5 covers the top of the printing arm 1, and the two are connected by fasteners such as screws and bolts. Multiple reinforcing plates 100 are installed side by side along the length of the printing arm 1 to improve strength and stability. Multiple through holes 101 are provided on the reinforcing plates 100 and the printing arm 1 to dissipate heat and reduce weight. The printing arm 1 can be made of stainless steel. This printing arm 1 has high strength, large support force, strong compressive strength, stable structure, and is not easy to deform or sink, thus improving printing accuracy.

[0064] In some embodiments, the printing plate 2 can be made of aluminum-magnesium alloy, including a front panel 200, a back panel 201, and a honeycomb polygonal aluminum foil 202 disposed between the front panel 200 and the back panel 201. Edge sealing 203 is fixed around the printing plate 2, sealing all parts of the printing plate 2 into a whole. The honeycomb polygonal aluminum foil can be formed by bonding or welding multiple layers of aluminum foil to create a hexagonal (or other polygonal) honeycomb core, which is then covered with the aluminum front panel 200 to form a lightweight and high-strength sandwich structure. The polygonal units (such as hexagons) provide excellent compressive and shear strength while achieving high porosity of the material. This printing plate 2 is lightweight, has fast heat conduction and dissipation, and high flatness. When the printing plate 2 is transferred from the flash drying position of the printing machine 3 to the cooling position, it dissipates heat quickly. After cooling, it is moved under the printing head, and the screen descends for squeegee printing. This printing plate 2 can prevent excessive temperature and the resulting clumping of the ink on the screen, which could lead to screen blockage.

[0065] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
