Shelf is a combination of the base plate and pillars to place miscellaneous items shelves. Mostly supported by the bar bracket, with the base plate for support, unique shape, design, easy to load and unload, clean and bright, open design, so that storage is visible at a glance.
As the application of shelves in family life is becoming more and more widespread, many types of household goods are becoming more and more, so you need a shelf that can be tidied up and put away these household goods, and the design of the shelf is very simple and generous at the same time with the dexterity, so it is very useful for putting away household goods, the key is to facilitate the life goods can be very good to take without a lot of effort to find.
(1), unique structure: the combination of carbon steel chrome-plated mesh and pillar, its unique shape structure, dexterous design, easy to load and unload, clean and bright, strong carbon steel chrome-plated mesh can promote air circulation, reduce the accumulation of dust, open design, so that storage visible at a glance.
2, the hardness of the printing plastic head RTV silicone rubber in the vulcanization process by adjusting the amount of softener to control the hardness of the printing head. Hardness is usually expressed in terms of Shore hardness, which reflects the ability of the print head to resist deformation. When printing flat workpieces and gradation patterns, the hardness of the rubber head should be selected to obtain smaller deformation and lower dot gain; and when printing curved surface workpieces, softer rubber heads should be used to achieve relatively large Deformation. However, when the graphic on the flatbed printing plate is transferred to the surface of the surface of the substrate, it will be deformed. If the hardness of the plastic head is softer, the deformation will be greater. The choice of controlling the deformation of the printing head only depends on the hardness of the printing head. It is necessary to compensate for deformation when making a printing plate according to the deformation trend.
3. Deformation of the printing head The deformation of the printing head is the basis for ink transfer. However, this deformation is also the main reason for the deformation of the imprint. The complete transfer of the imprinting does not result in significant deformation, and it is best to control. The deformation amount is below 10MM, which means that the choice of the effective value of the cross-sectional area of ​​the printing head is 110% of the area of ​​the graphics when the center part is compressed 10MM. Sometimes the shape of the surface of the substrate is rather special. It can be designed as a plastic head whose deformation cross-sectional area is similar to the surface of the substrate according to the specific conditions to control the compression amount below 10 mm. Of course, the amount of deformation of the print head is related to the hardness. Selecting a harder head under the premise of controlling the amount of deformation below 10 mm can obtain an ideal print.
Fourth, pad printing equipment Pad printing machinery is a relatively simple structure in the printing machinery, mostly consists of the following components:
1. The workbench bench is used to place fixtures and substrates. The workbench of a monochrome pad printer is usually a three-part mechanism capable of three-dimensional position adjustment; the two-color pad printer workbench is mainly based on a shuttle workbench and can The two printing positions move back and forth to realize two-tone color printing; the multi-color printing machine includes a rotary table and a rotary table, which can perform continuous color printing, and the productivity is relatively high.
The automatic up and down of the printing plate reflects the direction of the development of modern printing machines. It greatly reduces the labor intensity of workers, can reduce production costs and increase labor productivity. In particular, pad printers for professional products, such as optical disc printers, do not need to manually disassemble worktables for printing materials.
2. Printing device The printing device is the core of the pad printing machine. It consists of a plastic head translation mechanism and a plastic head drop mechanism. The drop mechanism mainly completes the basic operations of ink sticking and lifting and printing and lifting; the plastic head translation mechanism uses To complete the reciprocating transformation of the rubber head at the plate position and the substrate position. Modern pad printing machines mainly have the basic movement of pneumatically controlled printing devices.
The adjustment of the drop motion of the glue head in the printing device is performed by adjusting the position of the magnetic induction switch of the machine side wall. The drop stroke of the rubber head directly affects the stamping force of the rubber head.
3. Ink supply device and squeegee device The ink supply device of the pad printer is also very simple. There are two ways to supply ink, ink cartridges for ink and ink roller for ink. Ink supply ink is ink and diluent is adjusted and packaged in the ink cartridge, inverted on the printing plate, using its own magnetic suction to the thin steel plate, the ink rod connected to the piston shaft can be reciprocally moved , To achieve overwrite ink and scrape ink. Most of the current printers in the domestic market are ink rollers for ink supply, the printing plate is placed at the front of the ink tank, and the scraper device with the ink and diluent at the rear end and the translation device of the plastic head are fixed together carries the ink coating roller itself. In the ink coating stage, the squeegee blade is in the raised position, and the ink coating roller is immersed in the ink tank. When the plastic head seat moves forward, the ink coating roller is driven to the surface of the printing plate to start coating, and then the squeegee falls down and scrapes the ink. Ink roller back to the starting position.
4. Control system The control system is used to arrange the above mechanical actions in an orderly manner to make the printing process automatic. Now the pad printer basically realizes microcomputer control, and the performance is relatively stable and reliable.
During the commissioning phase, the machine must be able to perform single-body motion tests, such as a plastic head dropping motion, a cyclic motion, and an idle stroke uniform ink motion. These actions have a single function button for individual control operations; in the normal production phase, the magnetic induction switch is equivalent. The position sensor sends a signal to the central microprocessor after detecting the position signal of the plastic head piston shaft. The central microprocessor then sends a voltage command to each control solenoid valve to push the cylinder to move. The printing machine continuously prints according to the printing process requirements.
Fifth, the status quo and development trend of the printing process Progress of printing technology is mainly reflected in the mainstream of printing, printing process is basically no much improvement, whether it is desktop publishing or direct plate-making, digital printing has no effect on the printing process, The ubiquitous printing industry that still exists in the special printing industry is still taking the photo film, corroding the printing plate, and printing a simple text block pattern with a pad printing device. With the progress of society, the use of printing methods to print beautifully-printed prints will become a kind of fashion. The printing process of printing will slowly move forward in the direction of environmental protection, security, digitalization, and high quality.
(2), flexible and versatile: the pillar has a groove circle for every inch, and the height of the mesh can be adjusted at will (increasing or decreasing every inch). Can be combined at will according to actual needs, can be extended to the left and right at will (the same width) or forward and backward at will connected (the same length). Plus a variety of accessories, can be combined into a variety of functional products, such as plus V hooks, light body tube, can be combined into a Coat Rack; plus the direction of the handle, wheels, can be combined into a food cart or cart; plus the separation piece, side piece, can be combined into a bookcase and so on.
(3), wide range of uses: product models and specifications are very complete, can be suitable for the needs of any space, can be composed of a series of products for different purposes, such as kitchen series, living room series, bedroom series, study office series, as well as shopping malls, hotels, factories or household series, product display shelves series, etc.
(4), the force is great: micro series can carry 50KG per layer of mesh, household series can carry 100-250KG per layer of mesh.
