[0002] At present, with the development of commercial advertising, screen printing is increasingly favored by the advertising printing industry for its advantages such as exquisite pictures and large sizes. Different printing platforms need to be selected for different canvases during the printing process. For example, some canvases are woven surfaces, and inkjet printing on their surfaces will cause ink penetration. After the ink penetrates into the printing platform, it will affect subsequent printing. At this time, it is necessary to select a printing platform whose surface does not contact the canvas and can handle the ink. For canvases that do not produce ink penetration, it is necessary to select a platform with a solid surface to eliminate processing errors and ensure printing effects. Therefore, corresponding printing platform tables need to be selected for printing processing of different canvases. The existing solution is to replace the processing table. This processing method is very troublesome, and frequent switching back seriously affects production efficiency.

The positioning mechanism includes an adjusting cylinder 5 and a positioning plate 6. There are two adjusting cylinders 5 and two positioning plates 6, which are respectively installed on two side panels. The two adjusting cylinders 5 are both vertically arranged and retract synchronously. A bearing member 7 is installed on the top of the piston rod of the adjusting cylinder 5.

The two positioning plates 6 are respectively installed on the two side panels and are respectively located on the top of the two adjusting cylinders 5. The platform assembly is installed on the printing frame 1 through the positioning mechanism and can be switched with the assistance of the positioning mechanism.

[0024] The platform assembly includes a mounting plate 2, an ink guide cylinder 3 and a plurality of printing tables. The mounting plate 2 is a polygonal plate and a mounting hole for installing the ink guide cylinder 3 is opened on its plate surface. There are two mounting plates 2 and the two are arranged parallel and opposite to each other. The plurality of printing tables are located between the two mounting plates 2. The two ends of the plurality of printing tables are respectively fixedly connected to the plate surfaces of the two mounting plates 2 to form an internal hollow cylinder structure. A limit plate 4 is fixedly provided on the plate surface of the mounting plate 2 away from the printing table. The limit plate 4 is a polygonal plate and the number of its sides is equal to the number of the printing tables. The plurality of plate edges of the limit plate 4 are respectively flush with the processing operation surfaces of the plurality of printing tables. When the processing surface of a printing table is horizontal, the plate edge of the limit plate 4 corresponding to it is horizontal. The ink guide cylinder 3 is a hollow cylinder. The ink guide cylinder 3 is fixedly inserted into the mounting holes of the two mounting plates 2 and its outer wall is fixedly connected to the mounting holes. The cylinder body of the ink guide cylinder 3 is located between the plurality of printing tables. The ink guide cylinder 3 is connected to the processing surface of one or more printing tables to recover the ink generated by printing.

[0025] Furthermore, the limiting plate 4 is a regular polygonal plate. As the best solution of this scheme, the limiting plate 4 and the mounting plate 2 are both equilateral triangular plates. The side length of the limiting plate 4 is smaller than the side length of the mounting plate 2 and the three plate edges of the limiting plate 4 are respectively parallel to the three plate edges of the mounting plate 2. The positioning plate 6 is a rectangular plate and one side plate edge is fixedly connected to the side plate of the printing frame 1. The positioning plate 6 is horizontally arranged and the plate edge of the positioning plate 6 away from the side plate on which it is located is located directly above the limiting plate 4. There are three printing platforms and they are the first platform plate 8, the second platform plate 9 and the third platform plate. 10, the first platform plate 8 and the second platform plate 9 are both rectangular plates, the edge of the mounting plate 2 corresponds to the edge of the second platform plate 9 and is flush with the surface of the second platform plate, when the printing cloth is ink-impermeable, the second platform plate can be used for printing, and when the second platform plate 9 is used for printing, the back of the printing cloth is attached to the surface of the second platform plate 9; two support rods are fixed on the first platform plate 8 along its length direction, and the two support rods are parallel to the length direction of the first platform plate 8 and are respectively close to the opposite side edges of the first platform plate 8, and the two support rods are square rods, and the mounting plate 2 corresponds to the first platform plate 8. The edge of a platform plate 8 is flush with the side edge of the support rod away from the first platform plate 8, and the support rod is used to support the printing cloth above the surface of the first platform plate 8 so that the printing cloth is spaced apart from the surface of the first platform plate 8; the surface of the third platform plate 10 is a V-shaped concave surface. As a further preferred embodiment, both side edges of the third platform plate 10 are provided with guide arc plates, and the edge of the mounting plate 2 corresponding to the third platform plate 8 is flush with the edge of the guide arc plates. When the third platform plate 10 is used for printing, the printing cloth is placed on the third platform plate 8 through two guide arc plates, and the third platform plate 8 There is space between the third platform plate 10 and the printing cloth, and multiple ink leakage ports connected to the ink guide tube 3 are provided on the lower edge of the concave surface of the third platform plate 10 and the plate surface of the first platform plate 8. The multiple ink leakage ports on the first platform plate 8 and the third platform plate 10 are evenly spaced and distributed in a direction parallel to the ink guide tube 3. The ink guide tube 3 is open at one end and closed at the other end. The open end of the ink guide tube 3 is connected to the negative pressure extraction device through a pipeline. When the first platform plate 8 or the third platform plate 10 is used for printing, the negative pressure extraction device will draw the ink dripping on the printing table surface into the ink guide tube and discharge it.

[0026] The printing platform of the device can quickly switch the printing platform to meet a variety of different printing requirements. When working, the two adjusting cylinders 5 are in an extended state. At this time, the printing platform at the top is in a working state, and the plate edge corresponding to the limit plate 4 is horizontally attached to the lower plate surface of the positioning plate 6. The adjusting cylinder 5 is in an extended state so that the platform assembly cannot rotate. When it is necessary to switch the printing platform, the adjusting cylinder 5 contracts to make the limit plate 4 move down a certain distance, and the platform assembly is rotated with the ink guide tube 3 as the axis to make the corresponding printing platform horizontal. The adjusting cylinder 5 is extended to make the plate edge of the limit plate 4 corresponding to the printing platform attached to the bottom surface of the positioning plate 6, thereby limiting the platform assembly. When printing on a printing cloth that will produce ink penetration, the first platform plate 8 or the third platform plate 10 is selected according to the ink penetration of the printing cloth. The ink enters the ink guide tube 3 through the ink leakage port and can be extracted by the negative pressure extraction device. When printing on a printing cloth that will not penetrate ink, the second platform plate 9 can be selected. The device can meet the printing requirements of various products, has a simple structural principle and is easy to use, which is conducive to popularization and use.

[0027] Example 2

[0028] Based on the structure of the printing frame and the positioning mechanism of Example 1, the mounting plate 2 and the limiting plate 4 of the platform assembly are both rectangular plates, there are four printing platforms and they are respectively the fourth platform plate, the fifth platform plate, the sixth platform plate and the seventh platform plate, the fourth platform plate and the sixth platform plate are located on the two opposite sides of the ink guide tube 3, the fourth platform plate and the sixth platform plate are respectively flush with the two long side edges of the mounting plate, the fifth platform plate and the seventh platform plate are respectively corresponding to the two short side edges of the mounting plate,

[0029] Two levers are fixedly provided on the upper edge of the fourth platform plate in the length direction, and the two levers are respectively located near the two side edges of the fourth platform plate, and the levers are square levers. The plate edge of the mounting plate corresponding to the fourth platform plate is flush with the side edge of the fourth platform plate away from the levers.

The structure and function of the fourth platform plate are similar to those of the first platform plate in Example 1; the sixth platform plate is a rectangular flat plate, and the plate edge of the mounting plate 2 corresponding to the sixth platform plate is flush with the plate surface of the sixth platform plate. The sixth platform plate has the same function as the second platform plate 9 in Example 1. The ink guide tube in this embodiment adopts the same structure as that in Example 1. The fifth platform plate and the seventh platform plate in this embodiment are used as auxiliary connecting elements to reinforce the structure of the platform assembly and are not used as printing platforms. Moreover, their widths are smaller than those of the fourth platform plate and the sixth platform plate. When printing on a printing cloth that may leak ink, the sixth platform plate is selected as the processing operation surface, and the leaked ink produced by printing is promptly extracted from the ink guide tube by the negative pressure device to avoid affecting the printing quality. When printing on a printing cloth that does not leak ink, the fourth platform plate is selected as the processing operation surface to meet the printing requirements. This embodiment, as a supplement to implementation 1, also has the advantages of easy use and convenient and quick switching of printing tables.
