Technical Field

The utility model relates to the technical field of printing processing, in particular to printing equipment, annular printing equipment and distributed printing equipment.

Background

In the prior art, various patterns need to be printed on the surface of a shoe material or a leather bag. Screen printing is also known as "screen printing" in which ink is transferred to a substrate through the mesh of an image-text portion by the extrusion of a squeegee to form an image-text identical to that of an original. The screen printing is widely applied because of simple equipment, convenient operation, simple printing and plate making, low cost and strong adaptability. In the existing multicolor screen printing, multi-printing system and multi-station printing are adopted, namely, on one printing production line, stations for printing each color are circularly arranged, and printing of a specific shape or a printing area is completed in one working procedure in a circulating manner. The arrangement of the whole printing production line is fixed, for example, the pattern to be printed has three colors, and the whole printing production line is designed according to the three colors so as to realize mass processing, but when the pattern to be printed has four colors, the whole printing production line cannot be suitable for use. The existing solution is to dismantle the original printing production line and then redesign and layout; or to find a new site to deploy a new printing line. The two solutions are not only high in cost, but also time-consuming and labor-consuming, and cannot quickly meet the printing requirement of the market on new patterns.

In addition, the existing printing production line occupies a large area, and for example, the chinese patent with application number CN200810142622.2 discloses a multicolor printing machine and a multicolor printing method thereof, the multicolor printing machine is arranged in a ring shape, which occupies a large area, is not beneficial to reducing factory rent of enterprises, and is not beneficial to reducing production cost of enterprises. In addition, the multicolor printing machine cannot meet the requirement that a certain color needs to be printed for multiple times, if the certain color needs to be printed for multiple times and be subjected to color register printing or the printing times required by each color are different, the printing of other stations needs to be suspended, and after one printing, printed products which are printed at one time need to be transferred among the processes and then return to the printing station for second printing, and the cost increase caused by the suspension of equipment and useless transfer among the printing processes is unacceptable for a production enterprise.

In order to solve the existing problems, the current chinese utility model patent with publication number CN210337230U discloses a full-automatic modular printing production line, including first lifting unit, feeding unit, second lifting unit and a plurality of printing module subassemblies, the both ends of printing production line are located respectively to first lifting unit and second lifting unit, and first lifting unit and printing module subassemblies are connected respectively to feeding unit's both ends, and between feeding unit and the second lifting unit are located to a plurality of printing module subassemblies that interconnect. The utility model discloses a can correspond the number that adopts printing module subassembly according to specific production conditions, solve the commonality problem of current printing production line effectively. Each printing module component can be repeatedly and circularly overprinted, the requirement that a certain color needs to be printed for multiple times can be effectively met without newly adding a printing device, the production cost is effectively saved while the production efficiency is improved, and a large amount of occupied area is saved. However, the above prior art still has the following disadvantages: the automatic feeding and discharging depends on the power of the conveying belt, and the conveying belt is worn too much after long-term use, so that problems are easy to occur in the conveying process; all the working procedures are positioned on the same linear conveying device, and the linear distance in the length direction of the required conveying track is longer, so that the requirement on the length of a field is greater, and the production cost is higher; the plate conveying mode is that a conveying belt is adopted, materials are conveyed to the plate by using friction force, and the abrasion to the conveying belt is large; the reliability and stability of the overall structure are to be enhanced.
