Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and more specifically, to a printing grid of a printing machine. Background Art

[0002] The printing machine belongs to a relatively representative printing device among stencil printing machines. Its printing plate is a silk screen woven from materials such as silk, with a criss-cross pattern and distinct warp and weft. There are already various types of screen printing machines, including flat, curved, formed, printing and dyeing, printed circuit, and new rotary types. Among them, the new rotary screen printing machine has relatively high speed and productivity. Its characteristic is that the screen is installed on a drum, and the ink is poured into the drum. When the machine is working, the drum rotates, and the rubber squeegee quickly prints the pattern onto the printing material. Screen printing was initially manually operated, with only one plate rack, one screen plate, and one template at that time. It was not until modern times that screen printing became mechanized and automated.

[0003] When the existing printing machine is printing, it generally presses the paper on the printing grid by moving the printing plate downward. However, since the items, patterns, and sizes to be printed each time are different, when it is necessary to adjust the size of the printing frame during later use, it does not have the ability to adjust, resulting in a problem of excessive blank printing area and waste of printing pigments. Therefore, a printing grid of a printing machine is introduced to solve such problems. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a printing grid of a printing machine. The technical problem to be solved by the utility model is: when the existing printing machine needs to adjust the size of the printing frame, it does not have the ability to adjust, resulting in a problem of excessive blank printing area and waste of printing pigments.

[0005] To achieve the above object, the utility model provides the following technical solution: a printing grid of a printing machine, including a grid assembly, and a lifting assembly is arranged on one side of the grid assembly;

[0006] The grid assembly includes a plurality of telescopic mechanisms;

[0007] The telescopic mechanism includes a first fixing rod, a first fixing piece is fixedly connected to one side of the first fixing rod, a bolt is arranged at the center of the first fixing piece, a telescopic rod is fixedly connected to the side of the first fixing rod away from the first fixing piece, a first locking hole is formed through the surface of the telescopic rod, a second fixing rod is sleeved on the surface of the telescopic rod, a second fixing piece is fixedly connected to the side of the second fixing rod away from the first fixing rod, a telescopic cavity is formed at the intersection of the second fixing rod and the telescopic rod, a plurality of second locking holes are formed on the surface of the second fixing rod, and clamping grooves are formed on one side of both the first fixing rod and the second fixing rod.

[0008] In a preferred embodiment, the grid assembly includes a fixed grid, on the outer sides of which clamping bars are fixedly connected. A printing screen is fixedly connected to the inner cavity of the fixed grid. A plurality of telescopic mechanisms are arranged on the outer side of the fixed grid. Fixing plates are fixedly connected to the outer sides of the telescopic mechanisms on both sides, and a plurality of fixing holes are formed on the surfaces of the fixing plates.

[0009] In a preferred embodiment, the lifting assembly includes a connecting bar, through which a locking bolt is penetrated. One end of the connecting bar is fixedly connected to a connecting column, and supporting legs are fixedly connected to the bottoms of the connecting columns. A telescopic column is fixedly connected to the top of the connecting column, and a cylinder is sleeved on the outer surface of the telescopic column.

[0010] In a preferred embodiment, a plurality of telescopic mechanisms are provided, and the plurality of telescopic mechanisms are connected by bolts.

[0011] In a preferred embodiment, the clamping bar fits with the clamping groove, and the thickness of the fixed grid is the same as that of the first fixing rod and the second fixing rod.

[0012] In a preferred embodiment, a lifting assembly is arranged on one side of each fixing plate, and the fixing plate and the lifting assembly are connected by a locking bolt to connect the fixing plate and the connecting bar.

[0013] The technical effects and advantages of the present utility model:

[0014] 1. By providing a grid assembly and a lifting assembly, the present utility model can directly control the telescoping between the cylinder and the telescopic column during later use. The telescopic column drives the connecting column and the connecting bar to move up and down, and the movement of the connecting bar drives the entire grid assembly to move, ensuring that the printed material can be smoothly removed after printing and the material to be printed can enter the printing area again.

[0015] 2. By providing a telescopic mechanism, during later use, since the size of each printing plate is different, the fixing method needs to be changed accordingly. Only by taking out the locking columns in a plurality of second locking holes and stretching the distance between the first fixing rod and the second fixing rod, the plurality of telescopic mechanisms can completely clamp the clamping bar, solving the problem that the existing printing machine lacks the adjustment ability when the printing frame size needs to be adjusted, resulting in too large blank printing area and wasting printing pigments.

A printing screen 13 is fixedly connected to the inner cavity of the fixed grid 11. A plurality of telescopic mechanisms 14 are arranged on the outer side of the fixed grid 11. Fixed plates 15 are fixedly connected to the outer sides of the telescopic mechanisms 14 on both sides. A plurality of fixing holes 16 are formed on the surfaces of the fixed plates 15.

[0027] Among them, the lifting component 2 includes a connecting strip 21. A locking bolt 22 penetrates through the surface of the connecting strip 21. One end of the connecting strip 21 is fixedly connected to a connecting column 23. Supporting legs 24 are fixedly connected to the bottoms of the connecting columns 23.
