When we are reading, we will see plastic size measuring instruments, which usually include rulers, triangles, and protractors. These drawing instruments are the enlightenment tools we know about the world. Straight rulers are used to draw straight lines, measuring the length of line segments, triangles are used to draw vertical lines, right angles, and protractors are used to draw angles and arcs. You may be concerned about how the text and scales on these stationery are printed?
There is no doubt that screen printing is still the best printing method. The consistency and three-dimensionality of the thickness of the ink layer that it has is still an advantage that other printing methods cannot match.
Initially, semi-automatic screen printing machines were widely used for printing. With the soaring labor costs in China, the inefficiency of semi-automatic printing presses has become increasingly unsuitable for the market's expansion demand for such measuring instruments. Screen printing machines for fully automatic measuring instruments. It came into being.
Some companies sell their products in a single product. They produce rulers, triangles, and protractors that are not delivered to customers in a complete package. They prefer a screen-fixing machine with a single fixture when purchasing screen printing machines. For example, the workbench only sets A fixture model for an instrument that prints only one product.
This type of screen printer is not the best option for companies that deliver products to customers in sets, because you may need to replace the fixtures of many instruments to print different products. These companies like to install different types on the workbench. Fixture model. For example, on the workbench, the model of the ruler, the set of triangles and the protractor is simultaneously made with a set of fixtures, and one machine can simultaneously print many types of products.
We can briefly introduce the fully automatic screen printing machine of this structure.
1) Feeding system.
How many kinds of instrument models are set on the workbench, how many kinds of stacking troughs are set above the feeding system, when the workbench drives the jig to move over the stacking trough, the product is automatically placed on the jig model, and then the workbench automatically rotates to printing The location is printed.
2) Workbench
The workbench can have four stations, six stations, eight stations, or even more. The more stations, the larger the size of the rotary table of the screen printing machine.
3) Screen printing system
The changes in the screen printing machine mainly vary around the workbench, the feeding system and the curing system, and the changes in the screen printing system are small. For those customers who require high precision, servo drive can be used.
4) Robot
A core element of traditional semi-automatic screen printing machine automation is the addition of a robot that can transfer printed products to the next process. At present, those who struggle to be at the forefront of the silk screen industry may be adding robots to their existing machines in the transitional stage before accepting automated baptism. Although there has not been a noticeable improvement in actual printing speed, there is no doubt that labor saving and labor intensity are reduced.
5) Curing system
Whether it is a UV curing device or an IR drying system is difficult to separate. The IR system achieves higher ink adhesion and lower machine cost. If you require high gloss and instant cure of the ink layer, then you can choose a UV curing system.
