Curved Screen Printing Industry Has A Long Way To Go

     Curved screen printing refers to screen printing on round shaped surfaces, such as various chemical bottles, medicine bottles, wine bottles, etc. most of them are cylindrical or almost cylindrical surfaces (the arc surface of flat bottles belongs to cylindrical surfaces), and there are few conical and spherical surfaces. Curved Screen Printing Industry Has A Long Way To Go

      No matter what kind of surface, there is only one printing principle, that is, the silk screen printing surface should make a pure rolling motion with the screen. During the rolling, the surface is tangent to the screen to deal with the falling point of the rubber scraper, and its extension line always points to the center of the circle.Curved Screen Printing Industry Has A Long Way To Go

      The design of curved screen printing machine is also based on this principle, which is generally driven by the toothed transmission of gear and rack. In telecontrol, the mesh plate is equivalent to a rack, the curved surface is equivalent to a gear, and the radius of the curved surface is the same as the radius of the common degree circle of the gear. Curved Screen Printing Industry Has A Long Way To Go

     During printing, the center of the curved surface and the center of the gear are coaxially adjusted.Curved Screen Printing Industry Has A Long Way To Go

       The screen printing rack and screen plate move horizontally and linearly, and the gear and the printing hand rotate around the concentric circle of the curved surface under the pull of the rack.Curved Screen Printing Industry Has A Long Way To Go

       In general, the bottle is clamped by positioning the bottle low and then jacking the bottle mouth tightly. For round bottles, there is a distance between the center of the bottle and the center of the circle. Curved Screen Printing Industry Has A Long Way To Go

      When printing circles and merging, there are two ways; One is to fix the center of the circle, the glue cannot be scraped, the bottle rotates around the center of the circle, and the screen moves horizontally. It is generally used for full automata.Curved Screen Printing Industry Has A Long Way To Go

      At present, the widely used curved screen printing models are mostly semi-automatic machines. Because this model is more suitable for some small and medium-sized enterprises and manufacturers with small batch orders,Curved Screen Printing Industry Has A Long Way To Go

      it has fast variety replacement and easy operation, and the purchase cost is lower than that of full-automatic screen printing machines. However, more workers are required to operate the surface treatment machine and curing machine.Curved Screen Printing Industry Has A Long Way To Go

       The automatic screen printing machine integrates automatic feeding, flame surface treatment, screen printing and curing. It has high efficiency and less labor. It is more suitable for manufacturers in large quantities.

       Automata can be divided into monochromatic automata and polychromatic automata. Multicolor automata are generally suitable for large quantities of orders over the years. Curved Screen Printing Industry Has A Long Way To Go

     They can print two to five colors on one machine, with the fastest production efficiency of 5000 P / h.Curved Screen Printing Industry Has A Long Way To Go

       Due to the high price of the full-automatic screen printing machine, the model must be selected when purchasing. The functions of the full-automatic machine produced by each factory are basically the same, but the structural design is very different. Curved Screen Printing Industry Has A Long Way To Go

      The key of mechanical design is the high efficiency, high-speed operation, smooth transfer of bottles and accurate chromatic printing of full automata. There are many defects in the mechanical design of the traditional silk screen printing machine.Curved Screen Printing Industry Has A Long Way To Go

       Let’s divide the board with monochrome automata (collectively referred to as 101).Curved Screen Printing Industry Has A Long Way To Go

1. When the bottle is moved from one station to another, the starting angle is small. It is easy to touch the groove edge and produce deviation when moving. Curved Screen Printing Industry Has A Long Way To Go

      Then when it is moved to the next groove position, the deviation falls. In this way, the more the transmission is, the more the deviation is, and the transmission will not be stable.Curved Screen Printing Industry Has A Long Way To Go

2. The transmission mechanism also has near dead center iron, large impact, vulnerable mechanism and can not run at high speed.Curved Screen Printing Industry Has A Long Way To Go

3. The swing of the silk screen printing position also affects the accuracy of the set.Curved Screen Printing Industry Has A Long Way To Go

4. The adjustment mechanism is cumbersome, and the adjustment personnel do not know its principle. In order to find the correct position, it takes a lot of effort, and it needs quite skilled adjustment personnel to adjust it well. Curved Screen Printing Industry Has A Long Way To Go

      In this way, it is not troublesome for many manufacturers to recruit workers of various types of work. Sometimes the manufacturers buy machines but can not find staff who can adjust the machines.Curved Screen Printing Industry Has A Long Way To Go

To solve this problem, some companies produce more stable and fast machinery. The mechanism is fully adjusted before leaving the factory. Its advantages are:Curved Screen Printing Industry Has A Long Way To Go

1. The iron degree of bottle delivery is 180 degrees, and the bottle is vertical at the moment of taking off and falling, so it will not touch the slot.Curved Screen Printing Industry Has A Long Way To Go

2. Large transmission angle, far away from the dead center, small force and high speed.Curved Screen Printing Industry Has A Long Way To Go

3. The silk screen printing mechanism is strengthened, which will not swing left and right, making the overprint accurate.Curved Screen Printing Industry Has A Long Way To Go

4. When changing varieties and tooling, it has many advantages, such as few transfers.Curved Screen Printing Industry Has A Long Way To Go

In recent years, due to t       he progress and development of other packaging printing processes, it has brought great impact to the curved screen printing industry (table labeling, set labeling). Curved Screen Printing Industry Has A Long Way To Go

       Therefore, some people think that curved screen printing has fallen behind, and some manufacturers love it to a certain extent.Curved Screen Printing Industry Has A Long Way To Go 

      However, we believe that the potential of curved screen printing has not been fully tapped, and there is still a long way to go for people in the industry to make continuous efforts.Curved Screen Printing Industry Has A Long Way To Go
