Description

Technical Field

[0001] The utility model specifically relates to the technical field of printing machines, in particular to a multi-station printing machine. Background Art

[0002] A printing press is a mechanical device used to transfer information such as text and images onto paper or other media. During printing, ink is filled in the concave part of the printing plate, and then a scraper is used to scrape off the excess ink on the surface. The ink in the concave part is transferred to the paper through pressure. There are many types of printing presses, such as monochrome printing presses and two-color printing presses. Two-color printing presses can also achieve monochrome printing.

[0003] However, in practice, people have noticed that there are two printing units inside a two-color printing press. When using a two-color printing press for single-color printing, only one of the printing mechanisms will be used, which will lose some efficiency and lead to reduced efficiency. In addition, the feed and discharge mechanisms need to be adjusted when switching between single-color printing and two-color printing. Since the feed and discharge mechanisms are very complicated, they are prone to damage when adjusted privately, resulting in the printing press being unusable. In addition, current printing presses cannot achieve single-color printing of two different patterns, so their use occasions are greatly limited. Utility Model Content

[0004] The purpose of the present utility model is to provide a multi-station printing machine that, by providing different numbers of material placement seats on an outer frame and switching between multiple stations, enables simultaneous material replacement or adjustment and printing, thereby improving printing efficiency, meeting different printing requirements, and enabling switching between two-color and single-color printing. In addition, the structure between the multi-station movable table and the material placement seats is relatively simple, making maintenance easier. The purpose is to solve the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A multi-station printing machine comprises a workbench, printing mechanisms are symmetrically mounted above the workbench, and a multi-station moving platform is arranged between two of the printing mechanisms;

[0010] As a further technical solution of the present invention, four groups of symmetrically arranged magnet blocks are provided in the outer frame, and each group of magnet blocks is embedded in the side surface of the outer frame in a rectangular array.

[0011] As a further technical solution of the present invention, a material placement seat is installed on the top of the multi-station mobile platform, and the material placement seat includes a supporting cross plate placed in the outer frame, and both ends of the supporting cross plate are integrally provided with limiting protrusions that are slidably connected to the positioning slide, and the limiting protrusions are placed in the positioning slide.

[0012] As a further technical solution of the present invention, magnetic metal is embedded on both sides of the supporting horizontal plate, and the magnetic metal on either side of the supporting horizontal plate is in contact with the magnet block;

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-10 The embodiment of the present utility model provides a multi-station printing machine, comprising a workbench 2, a printing mechanism symmetrically mounted above the workbench 2, and a multi-station moving platform 9 disposed between the two printing mechanisms;

[0034] The multi-station movable platform 9 includes an outer frame 91, which is provided with two groups of symmetrical positioning slots 92, and each group of the positioning slots 92 is movably connected to a supporting cross plate 101, and the bottom of the outer frame 91 is also fixedly connected to two symmetrical movable slide rails 95.

[0035] In this embodiment, a fixed slide groove 8 corresponding to the movable slide rail 95 is fixedly connected to the workbench 2, and the fixed slide groove 8 and the movable slide rail 95 are slidably connected.

[0036] In this embodiment, the bottom of the outer frame 91 is provided with reinforcing cross bars 94 in a rectangular array, and the bottom of the reinforcing cross bars 94 is fixedly connected to the movable slide rail 95 .

[0037] In this embodiment, four groups of symmetrically arranged magnet blocks 93 are provided in the outer frame 91 , and each group of magnet blocks 93 is embedded in the side surface of the outer frame 91 in a rectangular array.

[0038] In this embodiment, a material placement seat 10 is installed at the top of the multi-station movable table 9, and the material placement seat 10 includes a supporting cross plate 101 placed in the outer frame 91, and the two ends of the supporting cross plate 101 are integrally provided with a limiting protrusion 104 that is slidably connected to the positioning slide 92, and the limiting protrusion 104 is placed in the positioning slide 92.

[0039] In this embodiment, magnetic metal 102 is embedded on both sides of the supporting horizontal plate 101, and the magnetic metal 102 on any side of the supporting horizontal plate 101 is in contact with the magnet block 93;

[0040] The supporting transverse plate 101 is located above the reinforcing crossbar 94 , and a positioning groove 103 for positioning materials is provided above the supporting transverse plate 101 .

[0041] In this embodiment, the printing mechanism includes a column frame 3, a lifting plate 4 is slidably connected to the column frame 3, an electric push rod is provided above the column frame 3, the end of the electric push rod is fixedly connected to the lifting plate 4, and a printing template 6 is also provided on the side of the lifting plate 4.

[0042] In this embodiment, a printing plate cylinder 7 is movably connected above the printing template 6 , a printing drive mechanism 5 is further provided on the lifting plate 4 , and an end of the printing drive mechanism 5 is transmission-connected to the printing plate cylinder 7 .

[0043] By adopting the above technical solution, according to the printing requirements, when two-color printing is required, two material placement seats 10 can be placed diagonally in the outer frame 91, and the material is placed in the positioning groove 103 on the left support horizontal plate 101, and the outer frame 91 is pushed to move to the right until the left support horizontal plate 101 moves to the bottom of the printing mechanism on either side, and then the printing mechanism prints the material on the left. While printing, the staff places the material in the positioning groove 103 on the right support horizontal plate 101. When the material on the left is printed, the outer frame 91 is pushed to move to the left to print the material on the right, and at the same time, the left support horizontal plate 101 is pushed to move to the left. The supporting horizontal plate 101 slides to the other side in the outer frame 91, and then pushes the outer frame 91 to move to the right again. At this time, the material on the left moves to the bottom of the printing mechanism on the other side for secondary printing. At the same time, the supporting horizontal plate 101 on the right also slides to the side of the printing mechanism on the other side. The multi-station movable table 9 slides to the left again to perform secondary printing on the material on the right and replace the material on the left at the same time, and repeats this process in sequence, thereby realizing two-color printing of the material. At the same time, four material placement seats 10 can also be placed in a rectangular array in the outer frame 91 for monochrome printing, thereby improving printing efficiency and being suitable for multi-functional printing with different requirements.

[0044] In this embodiment, the column frame 3 is mainly composed of a mounting plate at the top and four support columns arranged in a rectangular array at the bottom, wherein the electric push rod is fixedly connected to the mounting plate, and the lifting plate 4 is slidably connected to the support columns; the electric push rod drives the lifting plate 4 to slide up and down in the support columns, thereby driving the printing template 6 to move.

[0045] In this embodiment, the bottom of the plate cylinder 7 is in contact with the printing template 6, and the printing drive mechanism 5 pushes the plate cylinder 7 to move on the printing template 6, and the ink on the plate cylinder 7 is printed on the workpiece through the holes on the printing template 6. Specific embodiments Example

[0046] When performing single-color printing of a single pattern, four identical material placement seats 10 are placed in a rectangular array on the inner side of the outer frame 91, and the pattern colors of the printing templates 6 in the two printing mechanisms are consistent;

[0047] Place the material in the left supporting horizontal plate 101 and place it in the positioning groove 103. Then push the outer frame 91 to move. The movable slide rail 95 at the bottom of the outer frame 91 slides in the fixed slide groove 8 to move the material on the left to the bottom of the printing mechanism.

[0048] The electric push rod in the printing mechanism drives the printing template 6 to fit on the material through the lifting plate 4, and the printing drive mechanism 5 drives the plate cylinder 7 to move on the printing template 6, so that the ink is printed on the material through the holes on the printing template 6. During the printing process, since the right support horizontal plate 101 is located on the side of the printing mechanism and does not participate in printing, the material to be printed is placed on the right support horizontal plate 101. After printing is completed, the electric push rod drives the lifting plate 4 to reset;

[0049] Push the outer frame 91 to the left, move the material on the right support horizontal plate 101 to the bottom of the printing mechanism for printing, then remove the material on the left support horizontal plate 101, and place the unprinted material again, and repeat this process to achieve monochrome printing of a single pattern. Specific embodiments Example

[0050] When performing monochrome printing of two patterns, four identical material placement seats 10 are placed in a rectangular array on the inner side of the outer frame 91, and the patterns and colors of the printing templates 6 in the two printing mechanisms are different;

[0051] Place the material in the left supporting horizontal plate 101 and place it in the positioning groove 103. Then push the outer frame 91 to move. The movable slide rail 95 at the bottom of the outer frame 91 slides in the fixed slide groove 8 to move the material on the left to the bottom of the printing mechanism.

[0052] The electric push rod in the printing mechanism drives the printing template 6 to fit on the material through the lifting plate 4, and the printing drive mechanism 5 drives the plate cylinder 7 to move on the printing template 6, so that the ink is printed on the material through the holes on the printing template 6. During the printing process, since the right support horizontal plate 101 is located on the side of the printing mechanism and does not participate in printing, the material to be printed is placed on the right support horizontal plate 101. After printing is completed, the electric push rod drives the lifting plate 4 to reset;

[0053] Push the outer frame 91 to the left, move the material on the right supporting horizontal plate 101 to the bottom of the printing mechanism for printing, then remove the material on the left supporting horizontal plate 101, and place the unprinted material again, and repeat this process to achieve monochrome printing of multiple patterns. Specific embodiments Example

[0054] When a pattern needs to be printed in two colors, two material placement seats 10 are taken and placed diagonally into the outer frame 91. The printing templates 6 in the two printing mechanisms have the same pattern but different colors.

[0055] Place material A into the positioning groove 103 on the left supporting horizontal plate 101, push the outer frame 91 to move to the right until the left supporting horizontal plate 101 moves to the bottom of the printing mechanism on either side, and then the printing mechanism prints the material A on the left. While printing, the staff places material B into the positioning groove 103 on the right supporting horizontal plate 101. When the left material A is printed, push the outer frame 91 to move to the left to print the right material B. At the same time, push the left supporting horizontal plate 101 to slide to the other side in the outer frame 91, so that the left material A moves to the side of the printing mechanism on the other side;

[0056] After the material B on the right is printed, the outer frame 91 is pushed to the right. At this time, the material A on the left is moved to the bottom of the printing mechanism on the other side for secondary printing. At the same time, the supporting horizontal plate 101 on the right also slides to the side of the printing mechanism on the other side, so that the material B on the right is moved to the side of the printing mechanism on the other side. After the material A on the left is printed, the multi-station movable table 9 slides to the left again to perform secondary printing on the material B on the right.

[0057] At the same time, the material A on the left side that has completed two-color printing is replaced, and the new material C is placed on the supporting horizontal plate 101 on the left. After the material B on the right is printed, the multi-station movable table 9 slides to the right again, and the material C on the left is moved to the printing mechanism on one side for printing, and the material B on the right is replaced at the same time. This cycle is repeated to achieve fast two-color printing.

[0058] The working principle of the present invention is as follows: when printing in monochrome, first take four identical material placement seats 10, and place the four identical material placement seats 10 in a rectangular array on the inner side of the outer frame 91, and place the material on the left support cross plate 101, and move the outer frame 91 to the right, so that the material on the left is moved to the bottom of the printing template 6 in the printing mechanism, and then the printing mechanisms on both sides work at the same time, and the electric push rod pushes the lifting plate 4 to move until the printing template 6 is attached to the surface of the material, and then the printing drive mechanism 5 drives the printing plate cylinder 7 to move on the printing template 6 to print the pattern on the material. At the same time, another group of materials is placed on the right support cross plate 101. After the printing of the material on the left is completed, the multi-station moving table 9 is pushed to the left to move, and the material on the right is moved to the bottom of the printing mechanism for printing. While printing, the printed material on the left is removed, and the material to be printed is placed again, and this process is repeated in sequence. By switching between multiple stations, monochrome rapid printing is achieved, thereby improving efficiency.

[0059] At the same time, it can also meet the requirements of two-color printing. Take two material placement seats 10, place the material placement seats 10 diagonally into the outer frame 91, place the material into the positioning groove 103 on the left support horizontal plate 101, push the outer frame 91 to move to the right until the left support horizontal plate 101 moves to the bottom of the printing mechanism on either side, and then the printing mechanism prints the material on the left. While printing, the staff places the material into the positioning groove 103 on the right support horizontal plate 101. When the material on the left is printed, push the outer frame 91 to the left. The multi-station movable table 9 slides to the left again to print the material on the right, and at the same time pushes the left supporting horizontal plate 101 to slide to the other side in the outer frame 91, and then pushes the outer frame 91 to move to the right again. At this time, the material on the left moves to the bottom of the printing mechanism on the other side for secondary printing. At the same time, the right supporting horizontal plate 101 also slides to the side of the printing mechanism on the other side, and the multi-station movable table 9 slides to the left again to print the material on the right for the secondary printing, and at the same time replaces the material on the left, and repeats in sequence to achieve fast two-color printing, which can meet the different requirements of occasions and increase usage functions.
